TITLE: Effects of valsartan alone versus valsartan/simvastatin combination on ambulatory blood pressure, C-reactive protein, lipoproteins, and monocyte chemoattractant protein-1 in patients with hyperlipidemia and hypertension.ABSTRACT: Angiotensin receptor blockers have been hypothesized to have synergistic effects with statins. We evaluated the effects of valsartan alone or combined with simvastatin on blood pressure (BP) and indexes of inflammation and oxidant stress in hypertensive patients with hyperlipidemia. In this double-blind trial, 404 patients were randomized to 12 weeks valsartan 160 mg (V) or valsartan 160 mg plus simvastatin 20 mg (V/S20) or 80 mg (V/S80). Twenty-four-hour mean ambulatory BP and biochemical marker measurements were recorded at baseline and study end. There were no statistically significant between-treatment differences for least-square mean reductions from baseline in systolic BP (V, -9.22; V/S20, -9.25; V/S80, -9.58 mm Hg; p <0.0001 for all within-treatment changes vs baseline). Plasma high-sensitivity C-reactive protein decreased with the combinations but not with V alone (least-square mean median change from baseline, -0.16, -0.20, -0.70 mg/L; p = 0.0001 for V/S80 vs baseline; p = 0.045 for V/S20 vs baseline; p = 0.0023 for V/S80 vs V/S20; p = 0.0045 for V/S80 vs V). Monocyte chemoattractant protein-1 was reduced by V, with no evidence for additional lowering with V/S combinations. In conclusion, addition of simvastatin to valsartan did not incrementally lower BP. However, V/S80 was superior to V and V/S20 in reducing high-sensitivity C-reactive protein.

TITLE: Efficacy and tolerability of naratriptan for short-term prevention of menstrually related migraine: data from two randomized, double-blind, placebo-controlled studies.ABSTRACT: In a pilot study, naratriptan was significantly more effective than placebo in preventing menstrually related migraine (MRM) when given as 1 mg twice daily for 5 days beginning 2 days before the predicted onset of MRM for up to 4 menstrual cycles.To evaluate the efficacy and tolerability of naratriptan for short-term prevention of MRM in 2 large, identically designed, randomized, double-blind, placebo-controlled, parallel-group studies.MRM was defined as any migraine beginning during the perimenstrual period (PMP). By definition, the PMP consisted of Days -2, -1, 1, 2, 3, and 4, with Day 1 being the first day of menstrual flow. Adult women were eligible if they reported a history of MRM, had regular menstrual cycles, and could predict within 2 days both the onset of menstrual flow and MRM. The studies comprised a baseline phase and a treatment phase. During the baseline phase, patients prophylactically treated their first PMP after the screening visit with single-blind placebo. Patients who documented an MRM while receiving placebo were eligible for the treatment phase. During the treatment phase, patients were randomized to receive either naratriptan 1 mg twice daily or placebo beginning 3 days before the predicted onset of MRM for a total of 6 days for 4 PMPs or 6 months, whichever occurred sooner. The primary efficacy endpoint was the mean percentage of treated PMPs without MRM per patient. Secondary efficacy endpoints included the percentage of patients who were free of MRM during all treated PMPs, the median number of days with MRM over 4 PMPs, and patient satisfaction. Safety and tolerability measures included adverse events, standard clinical laboratory tests, and vital signs.The intent-to-treat population was 287 in Study 1 (149 in the naratriptan group and 138 in the placebo group) and 346 in Study 2 (173 in each treatment group). Approximately 20% of randomized patients in each treatment group in Study 1 and 10% in each treatment group in Study 2 withdrew prematurely from the studies over the 4-month treatment period. The mean percentage of PMPs without MRM per patient was 38% and 34% among naratriptan-treated patients treating at least 1 PMP compared with 29% and 24% among placebo-treated patients in each respective study (P < .05 naratriptan vs placebo for both studies). Efficacy of naratriptan did not vary as a function of age, use of oral contraceptives, or use of migraine prophylaxis. More patients who had received naratriptan reported attacks posttreatment compared to patients who had received placebo. Among patients treating at least 1 PMP, the percentage of patients with no MRM in any treated PMP was significantly (P < .05) higher in the naratriptan group (11%; 19/173) than the placebo group (3%; 6 of 173) in Study 2. There were no differences in the percentages of patients with no MRM in any treated PMP in Study 1. The number of MRM days per patient across 4 PMPs was significantly lower in the naratriptan group than in the placebo group in both studies (median 5.0 days vs 6.5 days in Study 1 [P= .005] and 5.3 days vs 6.0 days in Study 2 [P= .018]). Significantly more patients receiving naratriptan were satisfied with the ability of naratriptan to control MRM either by preventing their occurrence or reducing their severity or duration compared with patients receiving placebo. No single drug-related adverse event was reported by more than 2% of patients in a treatment group in either study, and no serious drug-related adverse events were reported.Naratriptan 1 mg twice daily for 6 days per month is effective and well tolerated when used for short-term prevention of MRM. More patients receiving naratriptan than placebo were satisfied with treatment. The observed increase in posttreatment attacks needs further study.

TITLE: Continuous versus interrupted sutures for repair of episiotomy or second-degree perineal tears: a randomised controlled trial.ABSTRACT: To evaluate the repair techniques of continuous and interrupted methods for episiotomy or perineal tears.A randomised controlled trial.The Hospital Universitario Principe de Asturias, a state hospital belonging to the community of Madrid.Four hundred forty-five women who had undergone vaginal deliveries with episiotomies or second-grade tearing of the perineum between September 2005 and July 2007.One group was repaired with continuous, nonlocking sutures involving the vagina, perineum, and subcutaneous tissues. The other group had continuous, locking sutures of the vagina, interrupted sutures in the perineal muscles, and interrupted transcutaneous sutures. The threads used for stitching were identical in both groups.The participants were questioned regarding the sensation of pain and the use of painkillers on the second and the tenth days, and 3 months postpartum.When comparing the group with continuous suture to the group with interrupted sutures, the differences included less repair time (1 minute; P= 0.017) and less suture material used (relative risk [RR], 3.2, 95% CI: 2.6-4.0). The comparison of pain on the second and tenth days, and 3 months postpartum were not statistically different between the two techniques (RR, 1.08, 95% CI: 0.74-1.57; RR, 0.96, 95% CI: 0.59-1.55; and RR, 0.68, 95% CI: 0.19-2.46, respectively).Although we did not demonstrate that one technique was better than the other in the incidence of pain in the short or long term, we showed that episiotomy and perineal tear repairs with continuous suturing were quicker and used less suture material without an increase in complication than interrupted suturing.

TITLE: Efficacy and safety of a routine early invasive strategy in relation to time from symptom onset to fibrinolysis (a subgroup analysis of TRANSFER-AMI).ABSTRACT: The aim of this study was to assess the efficacy and safety of an early invasive strategy post-fibrinolysis in relation to time from symptom onset to fibrinolysis in patients with ST-elevation myocardial infarction (STEMI). The Trial of Routine Angioplasty and Stenting after Fibrinolysis to Enhance Reperfusion in Acute Myocardial Infarction (TRANSFER-AMI) randomized 1,059 patients receiving fibrinolysis for STEMI to an early invasive strategy versus standard therapy. The primary end point was the composite of death, reinfarction, recurrent ischemia, new or worsening heart failure, or cardiogenic shock at 30 days. In this post hoc subgroup analysis, we examined the effect of an early invasive strategy on efficacy and safety outcomes after stratification by time from symptom onset to fibrinolysis (<2 or ≥2 hours). Of 1,059 patients in TRANSFER-AMI, 557 (53%) received fibrinolysis <2 hours and 502 (47%) ≥2 hours after symptom onset. Compared to patients who received fibrinolysis within 2 hours of symptoms, patients who received fibrinolysis ≥2 hours after symptom onset had higher Global Registry of Acute Coronary Events risk scores (median 127 vs 122, p = 0.004). The effect of an early invasive strategy did not differ between symptom-to-fibrinolysis time strata for the primary efficacy end point (p-heterogeneity = 0.67), 30-day mortality, the composite of death or reinfarction at 30 days, 6 months, or 1 year, or bleeding (all p-heterogeneity >0.40). In conclusion, the efficacy and safety of an early invasive strategy in patients undergoing fibrinolysis for STEMI do not vary in relation to time (<2 or ≥2 hours) from symptom onset to fibrinolysis.

TITLE: Relaxin for the treatment of patients with acute heart failure (Pre-RELAX-AHF): a multicentre, randomised, placebo-controlled, parallel-group, dose-finding phase IIb study.ABSTRACT: Most patients admitted for acute heart failure have normal or increase blood pressure. Relaxin is a natural human peptide that affects multiple vascular control pathways, suggesting potential mechanisms of benefit for such patients. We assessed the dose response of relaxin's effect on symptom relief, other clinical outcomes, and safety.In a placebo-controlled, parallel-group, dose-ranging study, 234 patients with acute heart failure, dyspnoea, congestion on chest radiograph, and increased brain natriuretic peptide (BNP) or N-terminal prohormone of BNP, mild-to-moderate renal insufficiency, and systolic blood pressure greater than 125 mm Hg were recruited from 54 sites in eight countries and enrolled within 16 h of presentation. Patients were randomly assigned, in a double-blind manner via a telephone-based interactive voice response system, to standard care plus 48-h intravenous infusion of placebo (n=62) or relaxin 10 microg/kg (n=40), 30 microg/kg (n=43), 100 microg/kg (n=39), or 250 microg/kg (n=50) per day. Several clinical endpoints were explored to assess whether intravenous relaxin should be pursued in larger studies of acute heart failure, to identify an optimum dose, and to help to assess endpoint selection and power calculations. Analysis was by modified intention to treat. This study is registered with ClinicalTrials.gov, number NCT00520806.In the modified intention-to-treat population, 61 patients were assessed in the placebo group, 40 in the relaxin 10 microg/kg per day group, 42 in the relaxin 30 microg/kg per day group, 37 in the relaxin 100 microg/kg per day group, and 49 in the relaxin 250 microg/kg per day group. Dyspnoea improved with relaxin 30 microg/kg compared with placebo, as assessed by Likert scale (17 of 42 patients [40%] moderately or markedly improved at 6 h, 12 h, and 24 h vs 14 of 61 [23%]; p=0.044) and visual analogue scale through day 14 (8214 mm x h [SD 8712] vs 4622 mm x h [9003]; p=0.053). Length of stay was 10.2 days (SD 6.1) for relaxin-treated patients versus 12.0 days (7.3) for those given placebo, and days alive out of hospital were 47.9 (10.1) versus 44.2 (14.2). Cardiovascular death or readmission due to heart or renal failure at day 60 was reduced with relaxin (2.6% [95% CI 0.4-16.8] vs 17.2% [9.6-29.6]; p=0.053). The number of serious adverse events was similar between groups.When given to patients with acute heart failure and normal-to-increased blood pressure, relaxin was associated with favourable relief of dyspnoea and other clinical outcomes, with acceptable safety.

TITLE: Effect of heart rate on the pharmacokinetics of fentanyl in dogs anesthetized with isoflurane and hydromorphone.ABSTRACT: To compare the pharmacokinetics of fentanyl at lower (LHR) or higher heart rate (HHR) in dogs anesthetized with isoflurane.Prospective, randomized, crossover controlled trial.A group of six healthy 13-month-old male Beagle dogs weighing 9.9 ± 0.7 kg (mean ± standard deviation).Dogs were allocated to two treatments: LHR (HR: 45-75 beats minute) and HHR (HR: 100-130 beats minute). Anesthesia was maintained with isoflurane and hydromorphone (0.1 mg kg followed by 0.02-0.10 mg kg hour) for both treatments. Glycopyrrolate was administered in HHR to maintain HR within the desired range. Afterwards, fentanyl (20 μg kg) was intravenously administered over 5 minutes. Arterial blood samples were collected for plasma fentanyl concentration measurement by liquid chromatography/mass spectrometry. The pharmacokinetics of fentanyl were compared between treatments and the differences were considered significant at p < 0.05.A three-compartment model best fitted the changes in plasma fentanyl concentration. Clearance (CL; mL minute kg) was 33.2 (24.0-48.0) and 61.3 (44.5-72.7), maximum concentration (ng mL) 33.6 (23.4-36.6) and 20.0 (16.7-28.0), apparent volume of the rapid peripheral compartment (mL kg) 436 (352-723) and 925 (499-1887), apparent volume at steady state (mL kg) 4064 (3453-6546) and 7195 (5077-8601), cardiac index (CI; mL minute m) 2.83 (1.98-3.67) and 4.91 (3.22-6.09) and HR (beats minute) 68 (49-72) and 120 (102-129) for LHR and HHR, respectively, with significant differences between treatments. Significant correlations (0.92 and 0.90) were found between CI and CL, and between HR and CL, respectively.The increase in HR and the resultant improvement in cardiac output increased fentanyl CL and volume of distribution, which resulted in a decrease in plasma fentanyl concentration in isoflurane-anesthetized dogs.

TITLE: Quercetin reduces illness but not immune perturbations after intensive exercise.ABSTRACT: To investigate the effects of quercetin supplementation on incidence of upper respiratory tract infections (URTI) and exercise-induced changes in immune function.Trained male cyclists (N=40) were randomized to quercetin (N=20) or placebo (N=20) groups and, under double-blind procedures, received 3 wk quercetin (1000 mg.d(-1)) or placebo before, during, and for 2 wk after a 3-d period in which subjects cycled for 3 h.d(-1) at approximately 57% Wmax. Blood and saliva samples were collected before and after each of the three exercise sessions and assayed for natural killer cell activity (NKCA), PHA-stimulated lymphocyte proliferation (PHA-LP), polymorphonuclear oxidative-burst activity (POBA), and salivary IgA output (sIgA).Pre- to postexercise changes in NKCA, PHA-LP, POBA, and sIgA did not differ significantly between quercetin and placebo groups. URTI incidence during the 2-wk postexercise period differed significantly between groups (quercetin=1/20 vs placebo=9/20, Kaplan-Meier analysis statistic=8.31, P=0.004).Quercetin versus placebo ingestion did not alter exercise-induced changes in several measures of immune function, but it significantly reduced URTI incidence in cyclists during the 2-wk period after intensified exercise.

TITLE: Pattern of iron chelation therapy in Egyptian beta thalassemic patients: Mansoura University Children's Hospital experience.ABSTRACT: The simultaneous use of deferoxamine (DFO) and deferiprone (DFP) has an additive effect in iron excretion in transfusion-dependent thalassemic patients.To evaluate the efficacy and safety of a prospective alternating therapy with DFO and DFP in patients with beta-thalassemia major (TM) and increased serum ferritin with DFO monotherapy alone.Sixty patients with beta-TM (mean age +/- SD, 13.05 +/- 6.1, range 10-20 years) with iron overload (serum ferritin > 2000 ng/ml) were studied. They received DFO at a daily dose of 40 mg/kg/day for 5-7 nights/week for the past several years. These patients were randomly assigned either to continue treatment with DFO alone (DFO group, n = 30) or prospectively receive additional alternating therapy with DFP at 75 mg/kg/day for 4 days/week and DFO for the other 2 days/week (alternating therapy group, n = 30). The efficacy of both groups was assessed by measurements of serum ferritin, echocardiography, and 24 h urine iron excretion (UIE) levels throughout 1 year follow-up.In the 60 evaluable patients, the mean serum ferritin ( +/- SD) fell dramatically from 4500 ( +/- 1250) ng/ml at the start of the study to 1250 ( +/- 750) ng/ml (alternate therapy group; P < 0.001) at the end of the study. There was also a significant improvement in the myocardial function as assessed by the ejection fraction (P < 0.002) and fractional shortening (P < 0.01) in those patients on alternate therapy for 1 year. Their mean urinary iron excretion elevated from 0.41 +/- 0.27 to 0.76 +/- 0.49 mg/kg/24 h (P < 0.003). There was a significant difference between both groups as regard the studied parameters at the end of the study. Whereas, there was no statistical difference as regard the studied parameters at the start and the end of the study in the DFO group. No significant adverse effects had occurred in both groups that necessitated withdrawal from the study.beta-Thalassemic major patients with transfusional iron overload can be safely and effectively treated with an alternate therapy of DFO/DFP with a progressive fall in the mean serum ferritin and significant improvement of myocardial performance.

TITLE: The effect of a multispecies probiotic on the intestinal microbiota and bowel movements in healthy volunteers taking the antibiotic amoxycillin.ABSTRACT: One of the side effects of antimicrobial therapy is a disturbance of the intestinal microbiota potentially resulting in antibiotic-associated diarrhea (AAD). In this placebo-controlled double-blind study, the effect of a multispecies probiotic on the composition and metabolic activity of the intestinal microbiota and bowel habits was studied in healthy volunteers taking amoxycillin.Forty-one healthy volunteers were given 500 mg amoxycillin twice daily for 7 days and were randomized to either 5 g of a multispecies probiotic, Ecologic AAD (10(9) cfu/g), or placebo, twice daily for 14 days. Feces and questionnaires were collected on day 0, 7, 14, and 63. Feces was analyzed as to the composition of the intestinal microbiota, and beta-glucosidase activity, endotoxin concentration, Clostridium difficile toxin A, short chain fatty acids (SCFAs), and pH were determined. Bowel movements were scored according to the Bristol stool form scale.Mean number of enterococci increased significantly from log 4.1 at day 0 to log 5.8 (day 7) and log 6.9 (day 14) cfu/g feces (P < 0.05) during probiotic intake. Although no other significant differences were observed between both intervention groups, within each group significant changes were found over time in both microbial composition and metabolic activity. Moreover, bowel movements with a frequency >or=3 per day for at least 2 days and/or a consistency >or=5 for at least 2 days were reported less frequently in the probiotic compared to the placebo group (48%vs 79%, P < 0.05).Apart from an increase in enterococci no significant differences in microbial composition and metabolic activity were observed in the probiotic compared with the placebo group. However, changes over time were present in both groups, which differed significantly between the probiotic and the placebo arm, suggesting that the amoxycillin effect was modulated by probiotic intake. Moreover, the intake of a multispecies probiotic significantly reduced diarrhea-like bowel movements in healthy volunteers receiving amoxycillin.

TITLE: Prophylactic mesh placement to prevent parastomal hernia, early results of a prospective multicentre randomized trial.ABSTRACT: Parastomal hernia (PSH) is a common complication after colostomy formation. Recent studies indicate that mesh implantation during formation of a colostomy might prevent a PSH. To determine if placement of a retromuscular mesh at the colostomy site is a feasible, safe and effective procedure in preventing a parastomal hernia, we performed a multicentre randomized controlled trial in 11 large teaching hospitals and three university centres in The Netherlands.Augmentation of the abdominal wall with a retromuscular light-weight polypropylene mesh (Parietene Light™, Covidien) around the trephine was compared with traditional colostomy formation. Patients undergoing elective open formation of a permanent end-colostomy were eligible. 150 patients were randomized between 2010 and 2012. Primary endpoint of the PREVENT trial is the incidence of parastomal hernia. Secondary endpoints are morbidity, pain, quality of life, mortality and cost-effectiveness. This article focussed on the early results of the PREVENT trial and, therefore, operation time, postoperative morbidity, pain, and quality of life were measured.Outcomes represent results after 3 months of follow-up. A total of 150 patients were randomized. Mean operation time of the mesh group (N = 72) was significantly longer than in the control group (N = 78) (182.6 vs. 156.8 min; P = 0.018). Four (2.7 %) peristomal infections occurred of which one (1.4 %) in the mesh group. No infection of the mesh occurred. Most of the other infections were infections of the perineal wound, equally distributed over both groups. No statistical differences were discovered in stoma or mesh-related complications, fistula or stricture formation, pain, or quality of life.During open and elective formation of an end-colostomy, primary placement of a retromuscular light-weight polypropylene mesh for prevention of a parastomal hernia is a safe and feasible procedure. The PREVENT trial is registered at: http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=2018 .

TITLE: Bone mineral density and inflammatory and bone biomarkers after darunavir-ritonavir combined with either raltegravir or tenofovir-emtricitabine in antiretroviral-naive adults with HIV-1: a substudy of the NEAT001/ANRS143 randomised trial.ABSTRACT: Osteopenia, osteoporosis, and low bone mineral density are frequent in patients with HIV. We assessed the 96 week loss of bone mineral density associated with a nucleoside or nucleotide reverse transcriptase inhibitor (NtRTI)-sparing regimen.Antiretroviral-naive adults with HIV were enrolled in 78 clinical sites in 15 European countries into a randomised (1:1), open-label, non-inferiority trial (NEAT001/ANRS143) assessing the efficacy and safety of darunavir (800 mg once per day) and ritonavir (100 mg once per day) plus either raltegravir (400 mg twice per day; NtRTI-sparing regimen) or tenofovir (245 mg once per day) and emtricitabine (200 mg once per day; standard regimen). For this bone-health substudy, 20 of the original sites in six countries participated, and any patient enrolled at one of these sites who met the following criteria was eligible: plasma viral loads greater than 1000 HIV RNA copies per mL and CD4 cell counts of fewer than 500 cells per μL, except in those with symptomatic HIV infection. Exclusion criteria included treatment for malignant disease, testing positive for hepatitis B virus surface antigen, pregnancy, creatinine clearance less than 60 mL per min, treatment for osteoporosis, systemic steroids, or oestrogen-replacement therapy. The two primary endpoints were the mean percentage changes in lumbar spine and total hip bone mineral density at week 48, assessed by dual energy x-ray absorptiometry (DXA) scans. We did the analysis with an intention-to-treat-exposed approach with antiretroviral modifications ignored. The parent trial is registered with ClinicalTrials.gov, number NCT01066962, and is closed to new participants.Between Aug 2, 2010, and April 18, 2011, we recruited 146 patients to the substudy, 70 assigned to the NtRTI-sparing regimen and 76 to the standard regimen. DXA data were available for 129, 121 and 107 patients at baseline, 48 and 96 weeks respectively. At week 48, the mean percentage loss in bone mineral density in the lumbar spine was greater in the standard group than in the NtRTI-sparing group (mean percentage change -2.49% vs -1.00%, mean percentage difference -1.49, 95% CI -2.94 to -0.04; p=0.046). Total hip bone mineral density loss was similarly greater at week 48 in the standard group than in the NtRTI-sparing group (mean percentage change -3.30% vs -0.73%; mean percentage difference -2.57, 95% CI -3.75 to -1.35; p<0.0001). Seven new fractures occurred during the trial (two in the NtRTI-sparing group and five in the standard group).A raltegravir-based regimen was associated with significantly less loss of bone mineral density than a standard regimen containing tenofovir disoproxil fumarate, and might be a treatment option for patients at high risk of osteopenia or osteoporosis who are not suitable for NtRTIs such as abacavir or tenofovir alafenamide.The European Union Sixth Framework Programme, Inserm-ANRS, Ministerio de Sanidad y Asuntos Sociales de España, Gilead Sciences, Janssen Pharmaceuticals, and Merck Laboratories.

TITLE: Singular and combined effects of nebivolol and lifestyle modification on large artery stiffness in hypertensive adults.ABSTRACT: We hypothesized that the combination of nebivolol and lifestyle modification would reduce large artery stiffness in middle-aged and older hypertensive adults more than either intervention alone.To address this, 45 men and women (age 40-75 years) with stage I hypertension were randomized to receive either nebivolol (NB; forced titration to 10 mg OD; n = 15; age 57.2 ± 11.4 years; body mass index [BMI] 30.8 ± 5.8 kg/m(2)), lifestyle modification (LM; 5-10% weight loss via calorie restriction and physical activity; n = 15; age 52.7 ± 8.5 years; BMI 33.9 ± 7.2 kg/m(2)) or nebivolol plus lifestyle modification (NBLM; n = 15; age 58.9 ± 9.4 years; BMI 32.5 ± 4.9 kg/m(2)) for 12 weeks. β-stiffness index, a blood-pressure-independent measure of arterial stiffness, and arterial compliance were measured via high-resolution ultrasound and tonometry at baseline and after the 12-week intervention. There was no difference between groups in age, body weight or composition, blood pressure, or in β-stiffness index or arterial compliance at baseline (all p > 0.05).Following the 12-week intervention, body weight decreased ~5% (p < 0.05) in the LM and NBLM groups but did not change from baseline in the NB group (p > 0.05). Supine brachial and carotid systolic and diastolic blood pressure declined following treatment in each of the groups (p < 0.05). However, the magnitude of reduction was not different (p < 0.05) between groups. β-stiffness index declined (-2.03 ± 0.60, -1.87 ± 0.83 and -2.51 ± 0.90 U) and arterial compliance increased similarly (both p > 0.05) in the NB, LM and NBLM groups, respectively.In summary, our findings indicate that the combination of nebivolol and lifestyle modification reduced large artery stiffness to a similar degree as either intervention alone in middle-aged and older hypertensive adults.

TITLE: Metoclopramide role in preventing ileus after cesarean, a clinical trial.ABSTRACT: Ileus is a common event following cesarean section. Early post-cesarean recovery is very important not only for the mother but also for the baby who is dependent on breastfeeding. This article aims to demonstrate the efficacy of metoclopramide for the prevention of ileus after cesarean.In this randomized controlled trial, 696 women scheduled for cesarean were randomized in two groups. Three hundred fifty-three persons settled in control group and 343 were assigned in intervention group who received an injection of 10-mg intramuscular metoclopramide prior to operation. After cesarean, the participants recorded the first flatus, defecation, feeling of hunger, feeding and ambulation in a questionnaire, and also their sense of bloating in a visual analog scale under supervision of a research assistant. The data was analyzed by SPSS 17, t test, and chi-square, while p < 0.05 was considered significant.The interval between cesarean and the first flatus (p < 0.0001), defecation (p < 0.0001), feeling of hunger (p < 0.0001), feeding (p = 0.007), and ambulation (p < 0.0001) were significantly shorter in the metoclopramide group. In addition, polytomous logistic regression analysis showed the metoclopramide group had less bloating with significant difference (OR = 2.83 and CI 1.91-4.21).Our study proved the functionality of metoclopramide in preventing ileus. As this drug is safe, tolerable, harmless, inexpensive and available, and also no definite method has been developed to prevent ileus after cesarean; yet, metoclopramide could be considered as a suitable option. Certainly with regard to some limitations in our study, further comprehensive studies are still required to ensure validity of the obtained results.

TITLE: The effects of probiotics on mental health and hypothalamic-pituitary-adrenal axis: A randomized, double-blind, placebo-controlled trial in petrochemical workers.ABSTRACT: The aim of this study was to determine effects of probiotic yogurt and multispecies probiotic capsule supplementation on mental health and hypothalamic-pituitary-adrenal axis in petrochemical workers.The present randomized double-blind, placebo-controlled trial was conducted on 70 petrochemical workers. Subjects were randomly divided into three groups to receive 100 g/day probiotic yogurt + one placebo capsule (n = 25) or one probiotic capsule daily + 100 g/day conventional yogurt (n = 25) or 100 g/day conventional yogurt + one placebo capsule (n = 20) for 6 weeks. Mental health parameters including general health questionnaire (GHQ) and depression anxiety and stress scale (DASS) scores were measured. Fasting blood samples were obtained at the beginning and 6 weeks after the intervention to quantify hypothalamic-pituitary-adrenal axis.After 6 weeks of intervention, a significant improvement of GHQ was observed in the probiotic yogurt (18.0 ± 1.5 vs. 13.5 ± 1.9, P = 0.007) and in the probiotic capsule group (16.9 ± 1.8 vs. 9.8 ± 1.9, P = 0.001), as well as a significant improvement in DASS scores in the probiotic yogurt (23.3 ± 3.7 vs. 13.0 ± 3.7, P = 0.02) and the probiotic capsule group (18.9 ± 3.2 vs. 9.4 ± 4.0, P = 0.006). However, there was no significant improvement in the conventional yogurt group (P = 0.05 for GHQ and P = 0.08 for DASS).The consumption of probiotic yogurt or a multispecies probiotic capsule had beneficial effects on mental health parameters in petrochemical workers.

TITLE: Docosahexaenoic acid supplementation and time at achievement of gross motor milestones in healthy infants: a randomized, prospective, double-blind, placebo-controlled trial.ABSTRACT: Docosahexaenoic acid (DHA) intake throughout the first year of life is associated with neurodevelopmental and neuropsychological benefits. Few studies have evaluated the role of DHA intakes on age at achievement of gross motor milestones.The objective was to assess the effects of DHA supplementation throughout the first year of life on the achievement of four gross motor milestones in healthy infants.In this multicenter prospective, randomized, double-blind, placebo-controlled trial, 1160 healthy neonates were assigned to receive supplementation with either 20 mg liquid DHA (n = 580) or placebo (n = 580) orally once daily throughout the first year of life. The primary endpoint was the time at achievement of 4 gross motor milestones (sitting without support, hands-and-knees crawling, standing alone, and walking alone). All analyses were performed on an intention-to-treat basis.The time to achievement of sitting without support was shorter (P < 0.001) in infants who received DHA [median: 26 wk; interquartile range (IQR): 24-29 wk] than in those who received placebo (27 wk; 26-31 wk). No significant difference between infants who received DHA or placebo was found for hands-and-knees crawling [39 wk (34-44 wk) compared with 40 wk (35-44 wk), respectively], standing alone [49 wk (43-55 wk) compared with 49 wk (44-57 wk), respectively], and walking alone [55 wk (50-60 wk) compared with 56 wk (52-61 wk), respectively].Despite the 1-wk advance in sitting without support associated with DHA supplementation, no demonstrable persistent effects of DHA supplementation on later motor development milestones were found. Thus, the long-term clinical significance of the 1-wk change in sitting without support, if any, remains unknown. This trial is registered at (clinicaltrials.gov) as NCT00610922.

TITLE: Fixation Using Alternative Implants for the Treatment of Hip Fractures (FAITH-2): The Clinical Outcomes of a Multicenter 2 × 2 Factorial Randomized Controlled Pilot Trial in Young Femoral Neck Fracture Patients.ABSTRACT: To assess whether the fixation method and vitamin D supplementation affect the risk of patient-important outcomes within 12 months of injury in nongeriatric femoral neck fracture patients.A pilot factorial randomized controlled trial.Fifteen North American clinical sites.Ninety-one adults 18-60 years of age with a femoral neck fracture requiring surgical fixation.Participants were randomized to a surgical intervention (sliding hip screw or cancellous screws) and a vitamin D intervention (vitamin D3 4000 IU daily vs. placebo for 6 months).The primary clinical outcome was a composite of patient-important complications (reoperation, femoral head osteonecrosis, severe femoral neck malunion, and nonunion). Secondary outcomes included fracture-healing complications and radiographic fracture healing.Eighty-six participants with a mean age of 41 years were included. We found no statistically significant difference in the risk of patient-important outcomes between the surgical treatment arms (hazard ratio 0.90, 95% confidence interval 0.40-2.02, P = 0.80) and vitamin D supplementation treatment arms (hazard ratio 0.96, 95% confidence interval 0.42-2.18, P = 0.92).These pilot trial results continue to describe the results of current fixation implants, inform the challenges of improving outcomes in this fracture population, and may guide future vitamin D trials to improve healing outcomes in young fracture populations. Although the pilot trial was not adequately powered to detect treatment effects, publishing these results may facilitate future meta-analyses on this topic.Therapeutic Level II.

TITLE: Randomized phase 2 study of irinotecan plus cisplatin versus gemcitabine plus vinorelbine as first-line chemotherapy with second-line crossover in patients with advanced nonsmall cell lung cancer.ABSTRACT: The current study was performed to compare the nonplatinum-based combination of gemcitabine and vinorelbine (GV) with the combination of irinotecan and cisplatin (IP) as first-line chemotherapy with second-line crossover in patients with advanced nonsmall cell lung cancer (NSCLC).Patients were randomly assigned to received either irinotecan at a dose of 65 mg/m(2) plus cisplatin at a dose of 30 mg/m(2) (Arm A) or gemcitabine at a dose of 900 mg/m(2) plus vinorelbine at a dose of 25 mg/m(2) (Arm B), each of which was administered on Days 1 and 8 every 3 weeks as the first-line therapy followed by crossover at the time of disease progression.A total of 146 patients were enrolled (75 patients in Arm A and 71 patients in Arm B); 138 patients were evaluable for tumor response and toxicity. During first-line therapy, IP was found to result in more grade 2+ nausea and vomiting (toxicity was graded according to the National Cancer Institute Common Toxicity Criteria [version 2.0]) (41% vs 12%; P = .0001) and alopecia (36% vs 10%; P = .0003). Pneumonitis was noted only with GV therapy (7% vs 0%; P = .058). During second-line therapy, IP was found to result in more grade 3 diarrhea (17% vs 2%; P = .039) and GV featured more cases of grade 3+ neutropenia (78% vs 40%; P = .0003). IP tended to generate more tumor responses (38% vs 26% as first-line therapy, and 30% vs 13% as second-line therapy) compared with GV. IP also demonstrated a favorable trend in median progression-free survival (4.6 months vs 3.8 months as first-line therapy and 4.5 months vs 2.6 months as second-line therapy) and overall survival (15.9 months vs 13.1 months; P = .3), but this difference was not statistically significant. The majority of patients who were refractory to IP also failed to respond to GV in the second-line setting.The platinum-based IP regimen appeared to be superior to the GV combination in terms of response rate. However, given the similar survival and better tolerability of the nonplatinum GV regimen, either treatment sequence would appear to be acceptable for the treatment of patients with advanced NSCLC.

TITLE: Luteal phase administration of paroxetine for the treatment of premenstrual dysphoric disorder: a randomized, double-blind, placebo-controlled trial in Canadian women.ABSTRACT: To evaluate the efficacy and safety of intermittent, luteal phase-only administration of paroxetine (10 mg and 20 mg) in the treatment of premenstrual dysphoric disorder (PMDD).In this multicenter trial, female outpatients (aged 18-45 years) from 4 Canadian health centers meeting DSM-IV criteria for PMDD were asked to perform daily ratings of their premenstrual symptoms for 2 consecutive menstrual cycles. Those displaying the symptoms of irritability and/or depressed mood in the luteal phases but not in the follicular phases of their menstrual cycles were randomly assigned to intermittent, luteal phase-only treatment with paroxetine 10 mg or 20 mg or placebo for 4 additional cycles. The primary efficacy endpoint was the percent change from baseline at study endpoint on the visual analog scale irritability score. Treatment differences were tested using analysis of covariance ad hoc. Estimated treatment mean differences and their associated 95% confidence intervals were also calculated. Data were collected from May 1999 to November 2002.Ninety-nine patients were included in the intention-to-treat population. When compared with placebo, patients treated with paroxetine 20 mg attained a significant reduction in irritability (difference in median percent change: -23.9, 95% CI = -51.3 to -6.2, p = .014; difference in mean absolute change: -18.6, 95% CI = -32.5 to -4.6, p = .007). A statistically significant difference was not observed when the patients treated with the lower dose of paroxetine (10 mg) were compared with placebo. Treatment was well tolerated with no unexpected side effects.Intermittent administration of paroxetine 20 mg significantly reduced irritability symptoms in patients with PMDD. These results are consistent with previous studies suggesting that PMDD may be treated effectively by luteal phase-only administration of a selective serotonin reuptake inhibitor.clinicaltrials.gov Identifier: NCT00620581.

TITLE: Randomized clinical trial comparing LigaSure haemorrhoidectomy with open diathermy haemorrhoidectomy.ABSTRACT: Milligan-Morgan excision haem-orrhoidectomy remains a very popular treatment modality for third and fourth degree haemorrhoids due to its cost effectiveness and good long-term results. The LigaSure tissue-sealing device is an alternative technique used in haemorrhoidectomy that has been shown to produce favourable results. The aim of this study was to assess the effectiveness of the LigaSure tissue sealing device in comparison with conventional diathermy haemorrhoidectomy.A prospective clinical trial was conducted. Patients with newly diagnosed haemorrhoids requiring haemorrhoidectomy were randomized to either LigaSure haemorrhoidectomy or diathermy haemorrhoidectomy. Surgical technique and postoperative care was standardized. Outcome measures were operative time and bleeding, postoperative pain (measured on a visual analogue scale) and rate of wound healing.We randomized 44 patients, 22 to LigaSure and 22 to diathermy; 43 patients were evaluated. They were aged between 19 and 71 years. There were no differences in patient demographics or type of haemorrhoid being operated on. LigaSure haemorrhoidectomy had a significantly lower mean operative time and intraoperative bleeding. At 3 weeks after surgery, haemorrhoidectomy performed with LigaSure had an odds ratio for complete epithelialization of 3.1 over diathermy (95% CI 1.2-8.2). There was no difference in postoperative pain.LigaSure haemorrhoidectomy is superior to diathermy for open haemorrhoidectomy.

TITLE: A randomised, parallel-group comparison study of diquafosol ophthalmic solution in patients with dry eye in China and Singapore.ABSTRACT: To compare the efficacy and safety of 3% diquafosol ophthalmic solution with those of 0.1% sodium hyaluronate ophthalmic solution in patients with dry eye in China and Singapore.A total of 497 patients with dry eye (Schirmer's test, 5 mm; fluorescein and RB score, 3 points) from China and Singapore were randomised to receive either diquafosol ophthalmic solution (diquafosol) or sodium hyaluronate ophthalmic solution (HA) at 1:1 ratio. The fluorescein staining scores and rose bengal (RB) subjective symptom scores and tear film breakup time were evaluated before treatment and 2 and 4 weeks after start of treatment.In the diquafosol group, changes in fluorescein and RB scores compared with baseline at week 4 or at the time of discontinuation were -2.1±1.5 and -2.5±2.0, respectively. Compared with the HA group, changes in fluorescein score were non-inferior and changes in RB score were superior (p=0.019). In addition, diquafosol and HA improved tear film breakup time by 1.046±1.797 and 0.832±1.775 s, respectively (no significant intergroup difference). Adverse event onset rates were 16.3% (40 of 246 subjects) and 10.0% (25 of 251 subjects) in the diquafosol group and HA group, respectively, with borderline significant intergroup differences (p=0.046), while adverse drug reaction incidence rates were 12.2% (30 of 246 subjects) and 6.0% (15 of 251 subjects), respectively (p=0.019). Only mild adverse drug reactions (>2%) in the form of eye discharge, itching or irritation were observed.Diquafosol improved fluorescein staining score in a manner similar to HA, and significantly improved RB score compared with HA.NCT01101984.

TITLE: Prevention of Early Ventilator-Associated Pneumonia after Cardiac Arrest.ABSTRACT: Patients who are treated with targeted temperature management after out-of-hospital cardiac arrest with shockable rhythm are at increased risk for ventilator-associated pneumonia. The benefit of preventive short-term antibiotic therapy has not been shown.We conducted a multicenter, double-blind, randomized, placebo-controlled trial involving adult patients (>18 years of age) in intensive care units (ICUs) who were being mechanically ventilated after out-of-hospital cardiac arrest related to initial shockable rhythm and treated with targeted temperature management at 32 to 34°C. Patients with ongoing antibiotic therapy, chronic colonization with multidrug-resistant bacteria, or moribund status were excluded. Either intravenous amoxicillin-clavulanate (at doses of 1 g and 200 mg, respectively) or placebo was administered three times a day for 2 days, starting less than 6 hours after the cardiac arrest. The primary outcome was early ventilator-associated pneumonia (during the first 7 days of hospitalization). An independent adjudication committee determined diagnoses of ventilator-associated pneumonia.A total of 198 patients underwent randomization, and 194 were included in the analysis. After adjudication, 60 cases of ventilator-associated pneumonia were confirmed, including 51 of early ventilator-associated pneumonia. The incidence of early ventilator-associated pneumonia was lower with antibiotic prophylaxis than with placebo (19 patients [19%] vs. 32 [34%]; hazard ratio, 0.53; 95% confidence interval, 0.31 to 0.92; P = 0.03). No significant differences between the antibiotic group and the control group were observed with respect to the incidence of late ventilator-associated pneumonia (4% and 5%, respectively), the number of ventilator-free days (21 days and 19 days), ICU length of stay (5 days and 8 days if patients were discharged and 7 days and 7 days if patients had died), and mortality at day 28 (41% and 37%). At day 7, no increase in resistant bacteria was identified. Serious adverse events did not differ significantly between the two groups.A 2-day course of antibiotic therapy with amoxicillin-clavulanate in patients receiving a 32-to-34°C targeted temperature management strategy after out-of-hospital cardiac arrest with initial shockable rhythm resulted in a lower incidence of early ventilator-associated pneumonia than placebo. No significant between-group differences were observed for other key clinical variables, such as ventilator-free days and mortality at day 28.

TITLE: Treatment-Induced Changes in Plasma Adiponectin Do Not Reduce Urinary Albumin Excretion in the Diabetes Prevention Program Cohort.ABSTRACT: Molecular data suggests that adiponectin may directly regulate urinary albumin excretion. In the Diabetes Prevention Program (DPP) we measured adiponectin and albuminuria before and after intervention, and we previously reported increases in adiponectin with interventions. Here we have used the DPP dataset to test the hypothesis that treatment-related increases in adiponectin may reduce albuminuria in obesity.We evaluated cross-sectional correlations between plasma adiponectin and urinary albumin excretion at baseline, and the relationship of treatment-related changes in adiponectin and albuminuria. Baseline and follow-up urine albumin to creatinine ratios (ACR (albumin to creatinine ratio)) and plasma adiponectin concentration were available in 2553 subjects.Adjusting for age, sex and race/ethnicity, we observed a statistically significant but weak inverse relationship between adiponectin and ACR at baseline (conditional Spearman's rho = (-) 0.04, p = 0.04). Although DPP treatments significantly increased plasma adiponectin, there were no treatment effects on ACR and no differences in ACR across treatment groups. There was a weak direct (not inverse) association between change in adiponectin and change in albuminuria (adjusted Spearman's rho = (+) 0.04, p = 0.03).In a large, well-characterized cohort of obese dysglycemic subjects we observed a weak inverse association between circulating adiponectin concentrations and urinary albumin excretion at baseline. Contrary to the hypothesized effect, treatment-related increases in plasma adiponectin were not associated with a reduction in ACR. The association of change in adiponectin with change in ACR should be assessed in populations with overt albuminuria before excluding a beneficial effect of increasing adiponectin to reduce ACR in obesity.

TITLE: A behavioral intervention reduces HIV transmission risk by promoting sustained serosorting practices among HIV-infected men who have sex with men.ABSTRACT: To examine factors that explain the effect of a cognitive-behavioral intervention on reductions in HIV transmission risk among HIV-infected men who have sex with men (MSM).Of the 1910 HIV-infected MSM screened, 616 participants considered to be at risk of transmitting HIV were randomized to a 15-session, individually delivered cognitive-behavioral intervention (n=301) or a wait-list control (n=315).Consistent with previous intent-to-treat findings, there was an overall reduction in transmission risk acts among MSM in both intervention and control arms, with significant intervention effects observed at the 5-, 10-, 15-, and 20-month assessments (risk ratios=0.78, 0.62, 0.48, and 0.38, respectively). These intervention-related decreases in HIV transmission risk acts seemed to be partially due to sustained serosorting practices. MSM in the intervention condition reported a significantly greater proportion of sexual partners who were HIV infected at the 5- and 10-month assessments (risk ratios=1.14 and 1.18).The Healthy Living Project, a cognitive-behavioral intervention, is efficacious in reducing transmission risk acts among MSM. This seems to have been due in large part to the fact that MSM in the intervention condition reported sustained serosorting practices.

TITLE: Assessment of the efficacy of a novel tailored vitamin K dosing regimen in lowering the International Normalised Ratio in over-anticoagulated patients: a randomised clinical trial.ABSTRACT: Current guidelines advocate using fixed-doses of oral vitamin K to reverse excessive anticoagulation in warfarinised patients who are either asymptomatic or have minor bleeds. Over-anticoagulated patients present with a wide range of International Normalised Ratio (INR) values and response to fixed doses of vitamin K varies. Consequently a significant proportion of patients remain outside their target INR after vitamin K administration, making them prone to either haemorrhage or thromboembolism. We compared the performance of a novel tailored vitamin K dosing regimen to that of a fixed-dose regimen with the primary measure being the proportion of over-anticoagulated patients returning to their target INR within 24 h. One hundred and eighty-one patients with an index INR > 6·0 (asymptomatic or with minor bleeding) were randomly allocated to receive oral administration of either a tailored dose (based upon index INR and body surface area) or a fixed-dose (1 or 2 mg) of vitamin K. A greater proportion of patients treated with the tailored dose returned to within target INR range compared to the fixed-dose regimen (68·9% vs. 52·8%; P = 0·026), whilst a smaller proportion of patients remained above target INR range (12·2% vs. 34·0%; P < 0·001). Individualised vitamin K dosing is more accurate than fixed-dose regimen in lowering INR to within target range in excessively anticoagulated patients.

TITLE: Predictors of Recurrent Ischemic Stroke in Patients with Embolic Strokes of Undetermined Source and Effects of Rivaroxaban Versus Aspirin According to Risk Status: The NAVIGATE ESUS Trial.ABSTRACT: Embolic stroke of undetermined source (ESUS) identifies patients with cryptogenic ischemic stroke presumed due to embolism from several unidentified sources. Among patients with recent ESUS, we sought to determine independent predictors of recurrent ischemic stroke during treatment with aspirin or rivaroxaban and to assess the relative effects of these treatments according to risk.Exploratory analyses of 7213 participants in the NAVIGATE ESUS international trial who were randomized to aspirin 100 mg/day or rivaroxaban 15 mg/day and followed for a median of 11 months, during which time there were 309 first recurrent ischemic strokes (4.6% per year). Baseline features were correlated with recurrent stroke by multivariate analysis.The 7 independent predictors of recurrent stroke were stroke or transient ischemic attack (TIA) prior to the qualifying stroke (hazard ratio [HR] 2.03 95% confidence internal [CI] 1.58-2.60), current tobacco user (HR 1.62, 95% CI 1.24-2.12), age (HR 1.02 per year increase, 95%CI 1.01-1.03), diabetes (HR 1.28, 95% CI 1.01-1.64), multiple acute infarcts on neuroimaging (HR 1.49, 95% CI 1.09-2.02), aspirin use prior to qualifying stroke (HR 1.34, 95% CI 1.02-1.70), and time from qualifying stroke to randomization (HR .98, 95% CI .97-.99). The rate of recurrent stroke rate was 2.6% per year for participants without any of these risk factors, and increased by an average of 45% for each independent predictor (P < .001). There were no significant interactions between treatment effects and independent stroke predictors or stroke risk status.In this large cohort of ESUS patients, several features including prior stroke or TIA, advanced age, current tobacco user, multiple acute infarcts on neuroimaging, and diabetes independently identified those with an increased risk of ischemic stroke recurrence. The relative effects of rivaroxaban and aspirin were similar across the spectrum of independent stroke predictors and recurrent stroke risk status.

TITLE: Impact of male partner involvement on mother-to-child transmission of HIV and HIV-free survival among HIV-exposed infants in rural South Africa: Results from a two phase randomised controlled trial.ABSTRACT: The Sub-Saharan Africa region still remains the epicentre of the global HIV/AIDS epidemic. With regards to new paediatric HIV infections, almost 90% of new HIV infections are among children (aged 0-14 years), largely through mother to child transmission. Male Partner Involvement in Prevention of Mother to Child Transmission programmes is now strongly advocated as being key in improving infant outcomes. This study describes the role of Male Partner Involvement on infant HIV infection and mortality survival in the first year among HIV-exposed infants born from HIV positive mothers.This study was a two-phase, two condition (intervention or control) longitudinal study as part of a clinic-randomized Prevention of Mother to Child Transmission controlled trial. For Phase 1, female participants were recruited without their male partners. In Phase 2, both female and male participants were enrolled in the study as couples in order to encourage active Male Partner Involvement during pregnancy. Participants had two assessments prenatally (8-24 weeks and 32 weeks) and three assessments postnatally (6 weeks, 6 months, and 12 months).About 1424 women were eligible for recruitment into the study and 18 eligible women declined to participate. All women had a partner; 54% were unmarried, 26% were cohabiting, and 20% were married. Just over half (55%) of the women had been diagnosed with HIV during the current pregnancy. Phase 1 had significantly more HIV-infected infants than Phase 2 at 12-months postpartum (aOR = 4.55 [1.38, 15.07]). Increased depressive symptoms were associated with infant HIV infection at 12-months (aOR = 1.06 [1.01, 1.10]). Phase 1 also had a significantly greater proportion of dead and HIV-infected infants than Phase 2 at 12-months (aOR = 1.98 [1.33, 2.94]).Male partner involvement in antenatal care is critical in ensuring infant survival and HIV infection among children born to HIV-positive mothers. This study highlights the high risk of ante-and-post natal depression and underscores the need of screening for depression during pregnancy.ClinicalTrials.Gov; Trial Number NCT02085356.

TITLE: Efficacy and safety of etanercept in children and adolescents aged > or = 8 years with severe plaque psoriasis.ABSTRACT: Etanercept, a fully human soluble tumor necrosis factor (TNF)-alpha receptor, is approved in Europe for treatment of severe plaque psoriasis in children > or = 8 years. The efficacy and safety of etanercept for this population was evaluated in a retrospective analysis of a previous study, which included 211 children (4-17 years) with psoriasis involving > or = 10% body surface area and Psoriasis Area and Severity Index (PASI) > or = 12. In this subanalysis, subjects aged 8-17 years received once-weekly subcutaneous etanercept 0.8 mg/kg (< or = 50 mg) or placebo in double-blind fashion for 12 weeks, followed by 24 weeks of open-label etanercept. Baseline demographics and disease characteristics were similar across treatment arms (etanercept n = 95, placebo n = 97). At week 12, 54.7% subjects receiving etanercept versus 11.3% receiving placebo achieved 75% or greater improvement in PASI (PASI 75) compared with baseline (p < 0.001). PASI 50, PASI 90, and static Physician Global Assessment of psoriasis followed a similar pattern (p < 0.001). Efficacy during the open-label phase was sustained through Week 36. Exposure-adjusted rates of adverse events for etanercept were similar or lower than those for placebo. No appreciable differences were noted in the efficacy and safety profiles between the subjects aged > or = 8 years in this analysis and those in the original study population aged 4-17 years. In conclusion, etanercept provided significant, sustained improvement in disease severity and was well tolerated in children > or = 8 years with severe plaque psoriasis.

TITLE: Prediction of nonspecific side effects in rheumatoid arthritis patients by beliefs about medicines.ABSTRACT: This study examines the determinants of patients' side effects from arthritis medication. Proposed predictors were patients' beliefs about medications, objective disease activity, treatment regimen, and psychiatric and rheumatoid arthritis symptoms.In a longitudinal design, 100 rheumatoid arthritis outpatients were investigated at baseline and again at 6 months after receiving both pharmacologic and psychosocial treatment.Multivariate analyses showed no influence of disease status, type of treatment, or psychiatric or arthritis symptoms on side effects. Heightened concerns about arthritis medication at baseline predicted side effects at baseline (partial correlation r = 0.37, P < 0.001) and at 6 months (partial correlation r = 0.25, P < 0.001) after controlling for relevant disease- and treatment-related variables. In a cross-lagged panel analysis, prior experience with side effects from arthritis medication was ruled out as a cause of heightened concerns, indicating that negative beliefs genuinely contribute to side effects. A comparison of patients who did and did not start new medications showed no difference in side effects in patients with positive beliefs about medications, but led to significantly more side effects in patients with negative beliefs.Patients' beliefs about arthritis medications were stable and consistently associated with side effects. Patients with greater concerns about their arthritis medications are at higher risk for developing side effects, especially when starting new drugs. Identifying those patients is important to avoid premature drug discontinuation. Research into cause and preventability of negative attitudes to prescribed medicines is needed.

TITLE: Sex hormone binding globulin and sex steroids among premenopausal women in the diabetes prevention program.ABSTRACT: It is unknown whether intensive lifestyle modification (ILS) or metformin changes sex steroids among premenopausal women without a history of polycystic ovarian syndrome (PCOS).We examined 1-year intervention impact on sex steroids (estradiol, testosterone, dehydroepiandrosterone, and androstenedione [A4]) and SHBG and differences by race/ethnicity.A subgroup of Diabetes Prevention Program participants who were premenopausal, not using estrogen, without a history of PCOS or irregular menses, and who reported non-Hispanic white (NHW), Hispanic, or African-American race/ethnicity (n = 301).Randomization arms were 1) ILS with the goals of weight reduction of 7% of initial weight and 150 minutes per week of moderate intensity exercise, 2) metformin 850 mg twice a day, or 3) placebo.Neither intervention changed sex steroids compared to placebo. ILS, but not metformin, increased median SHBG by 3.1 nmol/L (~11%) compared to decreases of 1.1 nmol/L in the placebo arm (P < .05). This comparison remained significant after adjustment for changes in covariates including waist circumference. However, associations with glucose were not significant. Median baseline A4 was lower in Hispanics compared to NHWs (5.7 nmol/L vs 6.5 nmol/L, P < .05) and increases in A4 were greater in Hispanics compared to NHWs (3.0 nmol/ vs 1.2 nmol/L, P < .05), and these differences did not differ significantly by intervention arm. No other racial/ethnic differences were significant.Among premenopausal glucose-intolerant women, no intervention changed sex steroids. ILS increased SHBG, although associations with glucose were not significant. SHBG and sex steroids were similar by race/ethnicity, with the possible exception of lower baseline A4 levels in Hispanics compared to NHWs.

TITLE: Postoperative fentanyl patch versus subacromial bupivacaine infusion in arthroscopic shoulder surgery.ABSTRACT: The purpose of our study was to compare the effectiveness of subacromial bupivacaine infusion and a transdermal fentanyl patch in the treatment of postoperative pain after arthroscopic shoulder surgery.Sixty patients with rotator cuff disease scheduled for elective arthroscopic shoulder surgery were enrolled in the study. For the treatment of postoperative pain, 30 patients constituted group F and received a 12.0-μg/h fentanyl patch for 72 hours and saline solution infusion in a subacromial manner at the rate of 4 mL/h. The remaining 30 patients constituted group B and received a placebo patch and an infusion of 2.5-mg/mL bupivacaine in a subacromial manner for 72 hours. The primary outcome measure was the postoperative numerical rating scale pain score. The consumption of opioids, ibuprofen, and acetaminophen was also recorded. The Constant scores and general recovery were followed up until the 90th postoperative day.There was no statistically significant difference in the numerical rating scale scores (P = .60) between the groups. No differences in the use of rescue analgesic were observed except that the patients receiving bupivacaine used more ibuprofen (median, 1,200 mg v 600 mg) during the day of surgery (P = .042). No difference was found in general recovery between the groups.A fentanyl patch delivering 12-μg/h fentanyl offers an easy and safe treatment option as a part of multimodal analgesia with few adverse effects in the treatment of postoperative pain in a carefully selected patient group after arthroscopic shoulder surgery.Level I, randomized controlled trial.

TITLE: The role of therapeutic alliance in mindfulness interventions: therapeutic alliance in mindfulness training for smokers.ABSTRACT: Mindfulness-based interventions have enjoyed a marked increase in support within biomedical and psychological research and practice in the past two decades. Despite the widespread application of these treatments for a range of psychological and medical conditions, there remains a lack of consensus regarding mechanisms through which these interventions effect change. One plausible yet underexplored mechanism is the therapeutic alliance between participants and mindfulness instructors.In this report, data are presented on therapeutic alliance from the mindfulness arm (n = 37) of a randomized controlled trial of a mindfulness-based smoking cessation treatment.Results suggest that client-reported therapeutic alliance measured midtreatment did not significantly predict primary smoking outcomes. Alliance did predict improvement in posttreatment scores on several outcome variables linked to mindfulness practice, including emotion regulation (β = -.24, p = .042), mindfulness (β = .33, p = .007), negative affect (β = -.33, p = .040), as well as treatment compliance (β = .39, p = .011).Implications of these relationships and the possible role of therapeutic alliance in mindfulness treatments are explored.

TITLE: The long-term efficacy of medical male circumcision against HIV acquisition.ABSTRACT: In three randomized trials, medical male circumcision (MMC) reduced HIV acquisition in heterosexual men in sub-Saharan Africa by approximately 60%, after 21-24 months of follow-up. We estimated the 72-month efficacy of MMC against HIV among men retained in the Kisumu randomized trial, in which HIV acquisition was reduced by 60% after 24 months.From 2002 to 2005, 2784 men aged 18-24 were enrolled and randomized 1 : 1 to immediate circumcision or control. At trial end in December 2006, control men were offered free circumcision. Follow-up continued to September 2010. Cox proportional hazards regression incorporating stabilized inverse probability of treatment and censoring weights generated through marginal structural modeling, was used to account for potential time-varying confounding and censoring to estimate the efficacy of MMC on HIV risk.The cumulative 72-month HIV incidence was 7.21% [95% confidence interval (CI): 5.98-8.68%]: 4.81% among circumcised men, 11.0% among uncircumcised men. The crude hazard ratio of HIV seroconversion for circumcised vs. uncircumcised men was 0.38 [95% CI: 0.26-0.55]. In weight-adjusted Cox regression, the hazard ratio was 0.42 [95% CI: 0.26-0.66].The efficacy of MMC was sustained at 58% at 72 months, similar to overall findings of the three trials under conditions of randomization. These findings provide an estimate of the long-term efficacy of circumcision against HIV acquisition. Our results support programmatic scale-up recommendations that are based on assumptions of sustained efficacy.

TITLE: Combined effects of goserelin and tamoxifen on estradiol level, breast density, and endometrial thickness in premenopausal and perimenopausal women with early-stage hormone receptor-positive breast cancer: a randomised controlled clinical trial.ABSTRACT: This study is to investigate the effects of geserelin+tamoxifen (TAM) on estradiol level, breast density (BD), endometrial thickness (ET), and blood lipids in premenopausal and perimenopausal women with hormone receptor-positive early-stage breast cancer.This study recruited 110 premenopausal and perimenopausal patients with hormone receptor-positive early-stage breast cancer between 22 June 2008 and 31 December 2009 and randomly assigned them to receive either goserelin plus TAM or TAM alone for 1.5 years. Blood levels of sex hormones and lipids and ET were determined at 0, 3, 6, 12, and 18 months. Contralateral BD was also measured at 0, 12, and 18 months.Five participants dropped out of the goserelin plus TAM group, and two participants dropped out of the TAM-alone group before initiation of endocrine therapy. The rest of patients received scheduled treatment and 3 years of median follow-up. No serious adverse effects were observed, and only two local recurrences have been observed in these patients. Estradiol level and BD were lower in the goserelin plus TAM group than in the TAM-alone group (P<0.05). The endometrium in the goserelin plus TAM group was significantly thinner than that in the TAM-alone group (P<0.05), and women in the TAM-alone group exhibited endometrial thickening over the course of the study. Furthermore, no significant differences in blood lipid levels were reported between the two groups.The data from the current study demonstrated that the addition of goserelin to TAM results in downregulation of estradiol level, followed by significant reduction in BD and ET in premenopausal and perimenopausal women with hormone receptor-positive breast cancer, which may eventually lead to better outcome in these patients.

TITLE: The effect of bevacizumab versus ranibizumab in the treatment of corneal neovascularization: a preliminary study.ABSTRACT: To compare the short term effects of bevacizumab and ranibizumab injections on the regression of corneal neovascularization (NV).Sixteen eyes of 16 patients with corneal NV were randomly assigned for an injection with 2.5 mg of bevacizumab (group 1, n = 8) or 1 mg of ranibizumab (group 2, n = 8) through subconjunctival and intrastromal routes. The patients were prospectively followed-up for one month after the injections. Corneal NV areas, as shown on corneal slit-lamp photographs stored in JPEG format, were calculated using Image J software before the injection, one week after the injection, and one month after the injection. The corneal NV areas were compared before and after the injections.Seven women and nine men, with an average age of 51 years, presented with corneal NV secondary to herpetic keratitis (7 cases), graft rejection (6), chemical burn (1), pemphigoid (1), and recurrent ulcer (1). In group I, the preoperative corneal NV area (8.75 ± 4.33%) was significantly decreased to 5.62 ± 3.86% one week after the injection and to 6.35 ± 3.02% one month after the injection (p = 0.012, 0.012, respectively). The corneal NV area in group 2 also exhibited a significant change, from 7.37 ± 4.33% to 6.72 ± 4.16% one week after the injection (p = 0.012). However, no significant change was observed one month after the injection. The mean decrease in corneal NV area one month after injection in group 1 (28.4 ± 9.01%) was significantly higher than in group 2 (4.51 ± 11.64%, p = 0.001).Bevacizumab injection resulted in a more effective and stable regression of corneal NV compared to the ranibizumab injection. The potency and dose of these two drugs for the regression of corneal NV require further investigation.

TITLE: Insecticide-treated plastic sheeting for emergency malaria prevention and shelter among displaced populations: an observational cohort study in a refugee setting in Sierra Leone.ABSTRACT: A double-blind phase III malaria prevention trial was conducted in two refugee camps using pre-manufactured insecticide-treated plastic sheeting (ITPS) or untreated polyethylene sheeting (UPS) randomly deployed to defined sectors of each camp. In Largo camp the ITPS or UPS was attached to inner walls and ceilings of shelters, whereas in Tobanda the ITPS or UPS was used to line only the ceiling and roof. In Largo the Plasmodium falciparum incidence rate in children up to 3 years of age who were cleared of parasites and monitored for 8 months was 163/100 person-years under UPS and 63 under ITPS (adjusted odds ratio [AOR] = 0.40, 95% confidence interval [CI] = 0.33-0.47). In Tobanda incidence was 157/100 person-years under UPS and 134 under ITPS (AOR = 0.85, 95% CI = 0.75-0.95). Protective efficacy was 61% under fully lined ITPS and 15% under roof lined ITPS. Anemia rates improved under ITPS in both camps. This novel tool proved to be a convenient, safe, and long-lasting method of malaria control when used as a full shelter lining in an emergency setting.

TITLE: Lurasidone in the treatment of schizophrenia: a 6-week, placebo-controlled study.ABSTRACT: There is an unmet need in the treatment of schizophrenia for effective medications with fewer adverse effects.This study aims to evaluate the efficacy and safety of lurasidone, an atypical antipsychotic, for the treatment of schizophrenia.Patients with an acute exacerbation of schizophrenia were randomized to 6 weeks of double-blind treatment with once-daily, fixed-dose lurasidone 40 mg (N = 50), lurasidone 120 mg (N = 49), or placebo (N = 50). The primary efficacy measure was mean change from baseline to day 42 (last observation carried forward) in the Brief Psychiatric Rating Scale derived (BPRSd) from the Positive and Negative Syndrome Scale (PANSS).Mean change in BPRSd was significantly greater in patients receiving lurasidone 40 and 120 mg/day versus placebo (-9.4 and -11.0 versus -3.8; p = 0.018 and 0.004, respectively). Treatment with lurasidone 120 mg/day was superior to placebo across all secondary measures, including PANSS total (p = 0.009), PANSS positive (p = 0.005), PANSS negative (p = 0.011), and PANSS general psychopathology (p = 0.023) subscales and Clinical Global Impression of Severity (CGI-S; p = 0.001). Treatment with lurasidone 40 mg/day was superior to placebo on the PANSS positive subscale (p = 0.018) and CGI-S (p = 0.002). The most common adverse events for patients receiving lurasidone were nausea (16.2 versus 4.0 % for placebo) and sedation (16.2 versus 10.0 % for placebo). Minimal changes in weight, cholesterol, triglyceride, and glucose levels were observed.In this study, which was limited by a relatively high discontinuation rate, lurasidone provided effective treatment for patients with acute exacerbation of chronic schizophrenia and had minimal effects on weight and metabolic parameters.

TITLE: Epidural fentanyl for postoperative analgesia after lumbar canal decompression: a randomized controlled trial.ABSTRACT: Postoperative back pain is common after decompression surgery for lumbar stenosis and often delays discharge from hospital. Achieving regional analgesia by intraoperative delivery of epidural opiates after lumbar canal decompression is a promising approach to reduce postoperative pain and enhance early mobilization. However, there have been concerns about opiate-related complications, such as respiratory depression and urinary retention in what is generally an elderly population of patients.To assess the analgesic efficacy of bolus epidural fentanyl administered intraoperatively after lumbar decompression for degenerative canal stenosis.Patient-blinded randomized controlled trial conducted at two university neurosurgical centers.Adults (older than 18 years) with neurogenic claudication and/or lower limb radiculopathy and concordant lumbar spinal canal stenosis demonstrated on magnetic resonance imaging. Patients with previous lumbar spinal surgery, a contraindication to fentanyl, or requiring instrumentation were excluded.The primary outcome measure was patient-reported Visual Analogue Score (VAS) for pain recorded preoperatively, in recovery, and on the first and second postoperative days if the patient remained in the hospital. Secondary outcomes were duration of surgery, length of stay, and any side effects or complications.Patients underwent a one to three level lumbar canal decompression as required, via a midline incision, under general anesthesia. Before wound closure either no drug (control) or a 100-μg bolus of fentanyl was administered via an epidural catheter inserted 10 cm rostral to the operated level. Patients were blinded to group allocation, and analysis was by intention to treat. The trial was approved by the National Health Service Research Ethics Service and the Medicines and Healthcare products Regulatory Agency. No commercial or other source of funding was received.Sixty patients were randomized, 29 to fentanyl and 31 to control. Demographics, duration of surgery, and preoperative VAS were not significantly different between the groups. VAS in recovery was significantly lower in patients treated with fentanyl (mean [standard deviation]: 2.6 [2.7] vs. 4.7 [2.4]; p=.003). Later VAS and postoperative length of stay were similar between groups. More patients in the fentanyl group required temporary urinary catheterization, but there was no significant difference in the incidence of side effects.Bolus epidural fentanyl provides effective short-term postoperative analgesia after lumbar canal decompression and may be a useful adjunct to pain management in patients undergoing lumbar spine surgery.

TITLE: 2-year clinical and angiographic outcomes from a randomized trial of polymer-free dual drug-eluting stents versus polymer-based Cypher and Endeavor [corrected] drug-eluting stents.ABSTRACT: In the ISAR-TEST-2 (Intracoronary Stenting and Angiographic Results: Test Efficacy of Three Limus-Eluting Stents) randomized trial, a new-generation sirolimus- and probucol-eluting stent (Dual-DES) demonstrated a 12-month efficacy that was comparable to sirolimus-eluting stents (SES) (Cypher, Cordis Corp., Warren, New Jersey) and superior to zotarolimus-eluting stents (ZES) (Endeavor, Medtronic CardioVascular, Santa Rosa, California). The aim of the current study was to investigate the comparative clinical and angiographic effectiveness of SES, Dual-DES, and ZES between 1 and 2 years.Long-term polymer residue is implicated in adverse events associated with delayed vessel healing after drug-eluting stent therapy. The second-generation ZES utilizes an enhanced biocompatibility polymer system whereas a new-generation Dual-DES employs a polymer-free drug-release system.A total of 1,007 patients undergoing coronary stenting of de novo lesions in native vessels were randomized to treatment with SES (n = 335), Dual-DES (n = 333), or ZES (n = 339). Clinical follow-up was performed to 2 years. Angiographic follow-up was scheduled at 6 to 8 months and 2 years.There were no significant differences between groups regarding death/myocardial infarction (SES: 10.2% vs. Dual-DES: 7.8% vs. ZES: 9.2%; p = 0.61) or definite stent thrombosis (SES: 0.9% vs. Dual-DES: 0.9% vs. ZES: 0.6%; p = 0.87). Two-year target lesion revascularization (TLR) was 10.7%, 7.7%, and 14.3% lesions in the SES, Dual-DES, and ZES groups, respectively (p = 0.009). Incident TLR between 1 and 2 years in the Dual-DES group (0.9%) was significantly lower than in the Cypher SES group (3.6%) (p = 0.009), but comparable to the Endeavor ZES group (0.7%) (p = 0.72). These findings mirrored those observed for binary restenosis.At 2 years, there was no signal of a differential safety profile between the 3 stent platforms. Furthermore, the antirestenotic efficacy of both Dual-DES and ZES remained durable between 1 and 2 years, with Dual-DES maintaining an advantage over the entire 2-year period.

TITLE: Piperacillin-tazobactam versus carbapenem therapy with and without amikacin as empirical treatment of febrile neutropenia in cancer patients: results of an open randomized trial at a university hospital.ABSTRACT: Empirical beta-lactam monotherapy has become the standard therapy in febrile neutropenia. The aim of this study was to compare the efficacy and safety of piperacillin-tazobactam versus carbapenem therapy with or without amikacin in adult patients with febrile neutropenia.In this prospective, open, single-center study, 127 episodes were randomized to receive either piperacillin-tazobactam (4 x 4.5 g IV/day) or carbapenem [meropenem (3 x 1 g IV/day) or imipenem (4 x 500 mg IV/day)] with or without amikacin (1 g IV/day). Doses were adjusted according to renal function. Clinical response was determined during and at completion of therapy.One hundred and twenty episodes were assessable for efficacy (59 piperacillin-tazobactam, 61 carbapenem). Mean duration of treatment was 14.8 +/- 9.6 days in the piperacillin-tazobactam group and 14.7 +/- 8.8 days in the carbapenem group (P > 0.05). Mean days of fever resolution were 5.97 and 4.48 days for piperacillin-tazobactam and carbapenem groups, respectively (P > 0.05). Similar rates of success without modification were found in the piperacillin-tazobactam (87.9%) and in the carbapenem groups (75.4%; P > 0.05). Fungal infection occurrence rates were 30.5 and 18% in piperacillin-tazobactam and carbapenem groups, respectively (P = 0.05). Antibiotic modification rates were 30.5 and 13.1% (P = 0.02) and the addition of glycopeptides to empirical antibiotic regimens rates were 15.3 and 44.3% for piperacillin-tazobactam and carbapenem groups, respectively (P = 0.001). The rude mortality rates were 14% (6/43) and 29.3% (12/41) in piperacillin-tazobactam and carbapenem groups, respectively (P = 0.08).The effect of empirical regimen of piperacillin-tazobactam regimen is equivalent to carbapenem in adult febrile neutropenic patients.

TITLE: Afatinib versus methotrexate as second-line treatment in patients with recurrent or metastatic squamous-cell carcinoma of the head and neck progressing on or after platinum-based therapy (LUX-Head & Neck 1): an open-label, randomised phase 3 trial.ABSTRACT: Patients with recurrent or metastatic squamous-cell carcinoma of the head and neck (HNSCC) progressing after first-line platinum regimens have a poor prognosis and few treatment options. Afatinib, an irreversible ERBB family blocker, has shown efficacy in a phase 2 study in this setting. We aimed to assess the efficacy and safety of afatinib compared with methotrexate as second-line treatment in patients with recurrent or metastatic HNSCC progressing on or after platinum-based therapy.In this open-label, phase 3, randomised controlled trial conducted in 101 centres in 19 countries, we enrolled patients aged 18 years or older with histologically or cytologically confirmed HNSCC that was recurrent, metastatic, or both who had progressed on or after first-line platinum-based therapy, were not amenable for salvage surgery or radiotherapy, and who had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Previous treatment with more than one systemic regimen in this setting was not allowed; previous treatment with EGFR-targeted antibody therapy (but not EGFR-targeted tyrosine-kinase inhibitors) was allowed. We randomly assigned eligible patients in a 2:1 ratio to receive oral afatinib (40 mg/day) or intravenous methotrexate (40 mg/m(2) per week), stratified by ECOG performance status and previous EGFR-targeted antibody therapy for recurrent or metastatic disease. Randomisation was done centrally with an interactive voice or web-based response system. Clinicians and patients were not masked to treatment allocation; independent review of tumour response was done in a blinded manner. The primary endpoint was progression-free survival as assessed by an independent, central imaging review committee. Efficacy analyses were done in the intention-to-treat population and safety analyses were done in patients who received at least one dose of study drug. This ongoing study is registered with ClinicalTrials.gov, number NCT01345682.Between Jan 10, 2012, and Dec 12, 2013, we enrolled 483 patients and randomly assigned 322 to afatinib and 161 to methotrexate. After a median follow-up of 6·7 months (IQR 3·1-9·0), progression-free survival was longer in the afatinib group than in the methotrexate group (median 2·6 months [95% CI 2·0-2·7] for the afatinib group vs 1·7 months [1·5-2·4] for the methotrexate group; hazard ratio [HR] 0·80 [95% CI 0·65-0·98], p=0·030). The most frequent grade 3 or 4 drug-related adverse events were rash or acne (31 [10%] of 320 patients in the afatinib group vs none of 160 patients in the methotrexate group), diarrhoea (30 [9%] vs three [2%]), stomatitis (20 [6%] vs 13 [8%]), fatigue (18 [6%] vs five [3%]), and neutropenia (1 [<1%] vs 11 [7%]); serious adverse events occurred in 44 (14%) of afatinib-treated patients and 18 (11%) of methotrexate-treated patients.Afatinib was associated with significant improvements in progression-free survival and had a manageable safety profile. These findings provide important new insights into the treatment of this patient population and support further investigations with irreversible ERBB family blockers in HNSCC.Boehringer Ingelheim.

TITLE: Change of insulin sensitivity in hepatitis C patients with normal insulin sensitivity: a 5-year prospective follow-up study variation of insulin sensitivity in HCV patients.ABSTRACT: Hepatitis C virus (HCV) infection is associated with a high prevalence of diabetes mellitus (DM). Insulin resistance (IR) is known to play a crucial role in the development of DM in chronic hepatitis C (CHC) patients. We prospectively investigated changes of insulin sensitivity in CHC patients during a 5-year period and analysed the factors significantly associated with IR.Sixty-two CHC patients with normal insulin sensitivity (CHC group), and a healthy control group of 172 subjects matched by age, gender, body mass index and lifestyles were studied. We compared the initial baseline insulin sensitivity, metabolic parameters and incidence of IR at the end of the follow-up period between the two groups. The changes in insulin sensitivity, metabolic parameters and the development of IR were analysed as well as factors associated with the development of IR.IR developed in 22.5% of 62 CHC patients and 5.2% of 172 normal individuals (P < 0.001). HCV infection per se and the genotype 1 were independent risk factors for the development of IR. The duration of infection > or = 120 months, initial fasting glucose 90-100 mg/dL, fasting insulin > or = 10 microIU/mL and the homeostasis model assessment (HOMA-IR) 2.3-2.7 were significantly associated with the development of IR in the CHC group.HCV infection was an independent risk factor for the development of IR. All CHC patients, even those with normal insulin sensitivity, require careful monitoring for the development of IR.

TITLE: Improving contraceptive use among Latina adolescents: A cluster-randomized controlled trial evaluating an mHealth application, Health-E You/Salud iTu.ABSTRACT: To evaluate the effectiveness of Health-E You/Salud iTu, a mobile health application (app), on increasing knowledge, self-efficacy and contraception use among Latina adolescents, its impact on visit quality, and app satisfaction.This study used cluster-randomized controlled trial (CRCT) of 18 school-based health centers (SBHCs). Prior to the visit, intervention participants received the patient-centered contraceptive decision-making support app and controls answered sexual health questions on iPads. Participants completed a previsit questionnaire and 3 follow-up surveys (48 hours, 3-, and 6-months) after the recruitment visit (where intervention participants completed the app). Differences in adolescents' contraceptive knowledge, self-efficacy, and use over the 6-month follow-up were assessed by generalized mixed effects regression models.A total of 1,360 Latina adolescents participated; 57.2% responded to the 48-hour survey, 50.1% to the 3-month, 49.7% to the 6-month, and 42.3% to both the 3- and 6-month surveys. Health-E You users' demonstrated significant increases in pre-post knowledge (p < 0.001). Intervention participants who completed the follow-up survey reported greater increases in mean self-efficacy from baseline (23.2 intervention vs. 22.5 controls) to 6 months (26.1 vs. 23.4; b = 1.58, 95% CI 0.38-2.77, p = 0.01), and greater increases in non-barrier contraceptive use from baseline (29% intervention vs. 30% controls) to 3 months (63% vs. 45%; OR = 3.29, 95% CI 1.04-10.36, p = 0.04) and 6 months (63% vs. 44%; OR = 5.54, 95% CI 1.70-18.06, p = 0.005). Providers and adolescents reported high app satisfaction and stated it improved visit quality.While data suggest that Health-E You improved outcomes, findings must be interpreted cautiously. Intervention participants had higher baseline sexual activity rates, more recruitment visits for pregnancy testing, emergency contraception or birth control, and lower completion rates of follow-up surveys than controls.Despite declines in adolescent pregnancy in the United States, Latinas continue to have disproportionately high rates compared to white females. The Health-E You app may be an effective support tool for both adolescents and providers in SBHCs, and possibly other clinical settings, across the country to increase contraceptive use and thereby decrease unintended pregnancies. It could potentially reduce disparities in adolescent pregnancies and create more efficient visit time spent between clients and their providers.

TITLE: Randomized Trial of a Vaccine Regimen to Prevent Chronic HCV Infection.ABSTRACT: A safe and effective vaccine to prevent chronic hepatitis C virus (HCV) infection is a critical component of efforts to eliminate the disease.In this phase 1-2 randomized, double-blind, placebo-controlled trial, we evaluated a recombinant chimpanzee adenovirus 3 vector priming vaccination followed by a recombinant modified vaccinia Ankara boost; both vaccines encode HCV nonstructural proteins. Adults who were considered to be at risk for HCV infection on the basis of a history of recent injection drug use were randomly assigned (in a 1:1 ratio) to receive vaccine or placebo on days 0 and 56. Vaccine-related serious adverse events, severe local or systemic adverse events, and laboratory adverse events were the primary safety end points. The primary efficacy end point was chronic HCV infection, defined as persistent viremia for 6 months.A total of 548 participants underwent randomization, with 274 assigned to each group. There was no significant difference in the incidence of chronic HCV infection between the groups. In the per-protocol population, chronic HCV infection developed in 14 participants in each group (hazard ratio [vaccine vs. placebo], 1.53; 95% confidence interval [CI], 0.66 to 3.55; vaccine efficacy, -53%; 95% CI, -255 to 34). In the modified intention-to-treat population, chronic HCV infection developed in 19 participants in the vaccine group and 17 in placebo group (hazard ratio, 1.66; 95% CI, 0.79 to 3.50; vaccine efficacy, -66%; 95% CI, -250 to 21). The geometric mean peak HCV RNA level after infection differed between the vaccine group and the placebo group (152.51×10 IU per milliliter and 1804.93×10 IU per milliliter, respectively). T-cell responses to HCV were detected in 78% of the participants in the vaccine group. The percentages of participants with serious adverse events were similar in the two groups.In this trial, the HCV vaccine regimen did not cause serious adverse events, produced HCV-specific T-cell responses, and lowered the peak HCV RNA level, but it did not prevent chronic HCV infection.

TITLE: Evaluation of the gut microbiota after metformin intervention in children with obesity: A metagenomic study of a randomized controlled trial.ABSTRACT: Metformin, a first-line oral antidiabetic agent that has shown promising results in terms of treating childhood and adolescent obesity, might influence the composition of the gut microbiota. We aimed to evaluate whether the gut microbiota of non-diabetic children with obesity changes after a metformin intervention.The study was a multicenter and double-blind randomized controlled trial in 160 children with obesity. Children were randomly assigned to receive either metformin (1 g/day) or placebo for 6 months in combination with healthy lifestyle recommendations in both groups. Then, we conducted a metagenomic analysis in a subsample obtained from 33 children (15 metformin, 18 placebo). A linear mixed-effects model (LMM) was used to determine the abundance changes from baseline to six months according to treatment. To analyze the data by clusters, a principal component analysis was performed to understand whether lifestyle habits have a different influence on the microbiota depending on the treatment group.Actinobacteria abundance was higher after placebo treatment compared with metformin. However, the interaction time x treatment just showed a trend to be significant (4.6% to 8.1% after placebo vs. 3.8 % to 2.6 % after metformin treatment, p = 0.055). At genus level, only the abundance of Bacillus was significantly higher after the placebo intervention compared with metformin (2.5% to 5.7% after placebo vs. 1.5 % to 0.8 % after metformin treatment, p = 0.044). Furthermore, different ensembles formed by Firmicutes, Bacteroidetes, and Verrucomicrobia were found according to the interventions under a similar food consumption.Further studies with a large sample size controlled by lifestyle patterns are required in obese children and adolescents to clarify whether metformin might trigger gut microbiota alterations.Registered on the European Clinical Trials Database (EudraCT, ID: 2010-023061-21) on 14 November 2011.

TITLE: Secukinumab in patients with psoriatic arthritis and axial manifestations: results from the double-blind, randomised, phase 3 MAXIMISE trial.ABSTRACT: MAXIMISE (Managing AXIal Manifestations in psorIatic arthritis with SEcukinumab) trial was designed to evaluate the efficacy of secukinumab in the management of axial manifestations of psoriatic arthritis (PsA).This phase 3b, double-blind, placebo-controlled, multi-centre 52-week trial included patients (≥18 years) diagnosed with PsA and classified by ClASsification criteria for Psoriatic Arthritis (CASPAR) criteria, with spinal pain Visual Analogue Score ≥40/100 and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score ≥4 despite use of at least two non-steroidal anti-inflammatory drugs (NSAIDs). Patients were randomised (1:1:1) to secukinumab 300 mg, secukinumab 150 mg or placebo weekly for 4 weeks and every 4 weeks thereafter. At week 12, placebo patients were re-randomised to secukinumab 300/150 mg. Primary endpoint was ASAS20 (Assessment of SpondyloArthritis international Society) response with secukinumab 300 mg at week 12.Patients were randomly assigned; 167 to secukinumab 300 mg, 165 to secukinumab 150 mg and 166 to placebo. Secukinumab 300 mg and 150 mg significantly improved ASAS20 response versus placebo at week 12 (63% and 66% vs 31% placebo). The OR (95% CI) comparing secukinumab 300 mg and 150 mg versus placebo, using a logistic regression model after multiple imputation, was 3.8 (2.4 and 6.1) and 4.4 (2.7 and 7.0; p<0.0001).Secukinumab 300 mg and 150 mg provided significant improvement in signs and symptoms of axial disease compared with placebo in patients with PsA and axial manifestations with inadequate response to NSAIDs.NCT02721966.

TITLE: Bortezomib plus rituximab versus rituximab alone in patients with relapsed, rituximab-naive or rituximab-sensitive, follicular lymphoma: a randomised phase 3 trial.ABSTRACT: Bortezomib and rituximab have shown additive activity in preclinical models of lymphoma, and have been shown to be active and generally well tolerated in a randomised phase 2 study in patients with follicular and marginal zone lymphoma. We compared the efficacy and safety of rituximab alone or combined with bortezomib in patients with relapsed or refractory follicular lymphoma in a phase 3 setting.In this multicentre phase 3 trial, rituximab-naive or rituximab-sensitive patients aged 18 years or older with relapsed grade 1 or 2 follicular lymphoma were randomly assigned (1:1) to receive five 35-day cycles consisting of intravenous infusions of rituximab 375 mg/m(2) on days 1, 8, 15, and 22 of cycle 1, and on day 1 of cycles 2-5, either alone or with bortezomib 1·6 mg/m(2), administered by intravenous injection on days 1, 8, 15, and 22 of all cycles. Randomisation was stratified by FLIPI score, previous use of rituximab, time since last therapy, and region. Treatment assignment was based on a computer-generated randomisation schedule prepared by the sponsor. Patients and treating physicians were not masked to treatment allocation. The primary endpoint was progression-free survival analysed by intention to treat. This trial has been completed and is registered with ClinicalTrials.gov, number NCT00312845.Between April 10, 2006, and Aug 12, 2008, 676 patients were randomised to receive rituximab (n=340) or bortezomib plus rituximab (n=336). After a median follow-up of 33·9 months (IQR 26·4-39·7), median progression-free survival was 11·0 months (95% CI 9·1-12·0) in the rituximab group and 12·8 months (11·5-15·0) in the bortezomib plus rituximab group (hazard ratio 0·82, 95% CI 0·68-0·99; p=0·039). The magnitude of clinical benefit was not as large as the anticipated prespecified improvement of 33% in progression-free survival. Patients in both groups received a median of five treatment cycles (range 1-5); 245 of 339 (72%) and 237 of 334 (71%) patients in the rituximab and bortezomib plus rituximab groups, respectively, completed five cycles. Of patients who did not complete five cycles, most discontinued early because of disease progression (77 [23%] patients in the rituximab group, and 56 [17%] patients in the bortezomib plus rituximab group). Rates of adverse events of grade 3 or higher (70 [21%] of 339 rituximab-treated patients vs 152 [46%] of 334 bortezomib plus rituximab treated patients), and serious adverse events (37 [11%] patients vs 59 [18%] patients) were lower in the rituximab group than in the combination group. The most common adverse events of grade 3 or higher were neutropenia (15 [4%] patients in the rituximab group and 37 [11%] patients in the bortezomib plus rituximab group), infection (15 [4%] patients and 36 [11%] patients, respectively), diarrhoea (no patients and 25 [7%] patients, respectively), herpes zoster (one [<1%] patient and 12 [4%] patients, respectively), nausea or vomiting (two [<1%] patients and 10 [3%] patients, respectively) and thrombocytopenia (two [<1%] patients and 10 [3%] patients, respectively). No individual serious adverse event was reported by more than three patients in the rituximab group; in the bortezomib plus rituximab group, only pneumonia (seven patients [2%]) and pyrexia (six patients [2%]) were reported in more than five patients. In the bortezomib plus rituximab group 57 (17%) of 334 patients had peripheral neuropathy (including sensory, motor, and sensorimotor neuropathy), including nine (3%) with grade 3 or higher, compared with three (1%) of 339 patients in the rituximab group (no events of grade ≥3). No patients in the rituximab group but three (1%) patients in the bortezomib plus rituximab group died of adverse events considered at least possibly related to treatment.Although a regimen of bortezomib plus rituximab is feasible, the improvement in progression-free survival provided by this regimen versus rituximab alone was not as great as expected. The regimen might represent a useful addition to the armamentarium, particularly for some subgroups of patients.Johnson & Johnson Pharmaceutical Research & Development and Millennium Pharmaceuticals, Inc.

TITLE: Effect of the gonadotropin-releasing hormone analogue triptorelin on the occurrence of chemotherapy-induced early menopause in premenopausal women with breast cancer: a randomized trial.ABSTRACT: Premenopausal patients with breast cancer are at high risk of premature ovarian failure induced by systemic treatments, but no standard strategies for preventing this adverse effect are yet available.To determine the effect of the temporary ovarian suppression obtained by administering the gonadotropin-releasing hormone analogue triptorelin during chemotherapy on the incidence of early menopause in young patients with breast cancer undergoing adjuvant or neoadjuvant chemotherapy.The PROMISE-GIM6 (Prevention of Menopause Induced by Chemotherapy: A Study in Early Breast Cancer Patients-Gruppo Italiano Mammella 6) study, a parallel, randomized, open-label, phase 3 superiority trial, was conducted at 16 sites in Italy and enrolled 281 patients between October 2003 and January 2008. The patients were premenopausal women with stage I through III breast cancer who were candidates for adjuvant or neoadjuvant chemotherapy. Assuming a 60% rate of early menopause in the group treated with chemotherapy alone, it was estimated that 280 patients had to be enrolled to detect a 20% absolute reduction in early menopause in the group treated with chemotherapy plus triptorelin. The intention-to-treat analysis was performed by including all randomized patients and using imputed values for missing data.Before beginning chemotherapy, patients were randomly allocated to receive chemotherapy alone or combined with triptorelin. Triptorelin was administered intramuscularly at a dose of 3.75 mg at least 1 week before the start of chemotherapy and then every 4 weeks for the duration of chemotherapy.Incidence of early menopause (defined as no resumption of menstrual activity and postmenopausal levels of follicle-stimulating hormone and estradiol 1 year after the last cycle of chemotherapy).The clinical and tumor characteristics of the 133 patients randomized to chemotherapy alone and the 148 patients randomized to chemotherapy plus triptorelin were similar. Twelve months after the last cycle of chemotherapy (last follow-up, August 18, 2009), the rate of early menopause was 25.9% in the chemotherapy-alone group and 8.9% in the chemotherapy plus triptorelin group, an absolute difference of -17% (95% confidence interval, -26% to -7.9%; P < .001). The odds ratio for treatment-related early menopause was 0.28 (95% confidence interval, 0.14 to 0.59; P < .001).The use of triptorelin-induced temporary ovarian suppression during chemotherapy in premenopausal patients with early-stage breast cancer reduced the occurrence of chemotherapy-induced early menopause.clinicaltrials.gov Identifier: NCT00311636.

TITLE: The impact of anesthesia on glycine absorption in operative hysteroscopy: a randomized controlled trial.ABSTRACT: Operative hysteroscopy requires the use of a distension medium and its absorption can lead to serious consequences from intravascular volume overload and water intoxication. We compared the impact of 2 types of anesthesia (general anesthesia and local anesthesia with sedation) on the absorption of glycine solution in operative hysteroscopy.A randomized controlled trial was conducted over a 17-month period. Eligible patients undergoing operative hysteroscopy for abnormal uterine bleeding were randomized in 2 groups: a general anesthesia group and a local anesthesia with sedation group. The primary outcome was the median absorption of the glycine solution (10th-90th percentile) measured with an automated tandem canister system. Secondary outcomes included incidence of absorption >1000 mL, discontinued surgery because of excessive absorption, median change in serum sodium, postoperative hyponatremia, and patients' postoperative quality of life at 24 hours (8-item Short Form Health Survey questionnaire). Nonparametric analyses (Mann-Whitney U test, χ(2) test, and Fisher exact test) were used.Of 142 eligible patients, 95 agreed to participate and were randomized. Women who underwent general anesthesia had a higher median absorption of the glycine solution (10th-90th percentile) compared with women who underwent local anesthesia with sedation (480 mL [76-1300 mL] vs 253 mL [70-728 mL]; P = 0.005). General anesthesia was also associated with a higher rate of glycine solution absorption (>1000 mL [20% vs 4%; P = 0.009]) and a more rapid rate of decrease in serum sodium (≥10 mEq/L [8% vs 0%; P = 0.005]) than local anesthesia with sedation. Postoperative quality of life measures as rated by the patients were comparable between the 2 groups.Compared with general anesthesia, local anesthesia with sedation is associated with less glycine absorption and should be considered the preferred method of anesthesia for operative hysteroscopy.

TITLE: Acupuncture for 'frequent attenders' with medically unexplained symptoms: a randomised controlled trial (CACTUS study).ABSTRACT: Medically unexplained physical symptoms (MUPS) are common and difficult to treat.To investigate the effectiveness of adding five-element acupuncture to usual care in 'frequent attenders' with MUPS.Randomised controlled trial in four London general practices.Participants were 80 adults with MUPS, consulting GPs ≥8 times/year. The intervention was individualised five-element acupuncture, ≥12 sessions, immediately (acupuncture group) and after 26 weeks (control group). The primary outcome was 26-week Measure Yourself Medical Outcome Profile (MYMOP); secondary outcomes were wellbeing (W-BQ12), EQ-5D, and GP consultation rate. Intention-to-treat analysis was used, adjusting for baseline outcomes.Participants (80% female, mean age 50 years, mixed ethnicity) had high health-resource use. Problems were 59% musculoskeletal; 65% >1 year duration. The 26-week questionnaire response rate was 89%. Compared to baseline, the mean 26-week MYMOP improved by 1.0 (95% confidence interval [CI] = 0.4 to 1.5) in the acupuncture group and 0.6 (95% CI = 0.3 to 0.9) in the control group (adjusted mean difference: acupuncture versus control -0.6 [95% CI = -1.1 to 0] P = 0.05). Other between-group adjusted mean differences were: W-BQ12 4.4 (95% CI = 1.6 to 7.2) P = 0.002; EQ-5D index 0.03 (95% CI = -0.11 to 0.16) P = 0.70; consultation rate ratio 0.90 (95% CI = 0.70 to 1.15) P = 0.4; and number of medications 0.56 (95% CI = 0.47 to 1.6) P = 0.28. All differences favoured the acupuncture group. Imputation for missing values reduced the MYMOP adjusted mean difference to -0.4 (95% CI = -0.9 to 0.1) P = 0.12. Improvements in MYMOP and W-BQ12 were maintained at 52 weeks.The addition of 12 sessions of five-element acupuncture to usual care resulted in improved health status and wellbeing that was sustained for 12 months.

TITLE: Obesity and COPD: associated symptoms, health-related quality of life, and medication use.ABSTRACT: There is little data about the combined effects of COPD and obesity. We compared dyspnea, health-related quality of life (HRQoL), exacerbations, and inhaled medication use among patients who are overweight and obese to those of normal weight with COPD.We performed secondary data analysis on 364 Veterans with COPD. We categorized subjects by body mass index (BMI). We assessed dyspnea using the Medical Research Council (MRC) dyspnea scale and HRQoL using the St. George's Respiratory Questionnaire. We identified treatment for an exacerbation and inhaled medication use in the past year. We used multiple logistic and linear regression models as appropriate, with adjustment for age, COPD severity, smoking status, and co-morbidities.The majority of our population was male (n = 355, 98%) and either overweight (n = 115, 32%) or obese (n = 138, 38%). Obese and overweight subjects had better lung function (obese: mean FEV(1) 55.4% ±19.9% predicted, overweight: mean FEV(1) 50.0% ±20.4% predicted) than normal weight subjects (mean FEV(1) 44.2% ±19.4% predicted), yet obese subjects reported increased dyspnea [adjusted OR of MRC score ≥2 = 4.91 (95% CI 1.80, 13.39], poorer HRQoL, and were prescribed more inhaled medications than normal weight subjects. There was no difference in any outcome between overweight and normal weight patients.Despite having less severe lung disease, obese patients reported increased dyspnea and poorer HRQoL than normal weight patients. The greater number of inhaled medications prescribed for obese patients may represent overuse. Obese patients with COPD likely need alternative strategies for symptom control in addition to those currently recommended.

TITLE: Impact of stimulant pharmacotherapy on sleep quality: post hoc analyses of 2 large, double-blind, randomized, placebo-controlled trials.ABSTRACT: Sleep disturbances may cause distress among individuals with attention-deficit/hyperactivity disorder (ADHD), but few studies have examined the impact of stimulant pharmacotherapy for ADHD on sleep in adults.These post hoc analyses included sleep data collected with the Pittsburgh Sleep Quality Index (PSQI), a self-rated questionnaire, from 831 adults with DSM-IV-TR-defined ADHD in 2 large, randomized, double-blind, placebo-controlled, forced-dose titration studies of lisdexamfetamine (N = 420; conducted from May 25, 2006, to November 16, 2006) and triple-bead mixed amphetamine salts (MAS) (N = 411; conducted from April 25, 2005, to November 4, 2005). Change from baseline to endpoint in PSQI clinically meaningful change categories (ie, "decrease," "no change," or "increase") was analyzed by treatment group in each study using the χ² test. The Cochran-Mantel-Haenszel method was used (1) to determine whether there was a statistically significant difference in Clinical Global Impressions-Improvement (CGI-I) score of 1 or 2 (improved) versus > 2 (not improved) relative to a decrease or an increase in PSQI and (2) to analyze shifts from good sleep at baseline (PSQI ≤ 5) to poor sleep at endpoint (PSQI > 5).Impaired sleep (PSQI score > 5) relative to baseline was demonstrated in 8.3% and 9.7% of the treatment and placebo groups, respectively (P = .18), in the MAS study and 7.7% and 8.2%, respectively (P = .03), in the lisdexamfetamine study. Clinically meaningful change in baseline to endpoint PSQI was not statistically significantly different between treatment and placebo groups in either study. A significant difference in CGI-I 1 and 2 relative to an increase or decrease in PSQI was found in both the triple-bead MAS (P < .0001) and the lisdexamfetamine (P = .0008) trials. More subjects with improved CGI-I rating of 1 or 2 had improvement in PSQI than had worsening.Approximately one-third of subjects receiving treatment or placebo had clinically meaningful sleep improvement, emphasizing that change in sleep quality during treatment may not necessarily be related to stimulant therapy. When managing complaints of sleep difficulties in ADHD subjects, clinicians should undertake a broad assessment and consider underlying conditions that may contribute to sleep disruption.clinicaltrials.gov Identifiers: NCT00334880 and NCT00152022.

TITLE: Central obesity and cardiovascular outcomes in patients with acute coronary syndrome: observations from the MERLIN-TIMI 36 trial.ABSTRACT: Despite the association of obesity with incident cardiovascular disease, obese patients with acute coronary syndrome (ACS) appear to have more favourable short-term outcomes. A study was undertaken to determine whether this 'obesity paradox' persists in the long term and to examine the specific relationship of central obesity with outcomes after ACS.The relationship was investigated between two measures of obesity-body mass index (BMI) and waist circumference (WC)-and 30-day and 1-year outcomes after ACS. 6560 patients with non-ST elevation ACS in the MERLIN-TIMI 36 trial were followed for 1 year. Patients were stratified into three BMI groups (<25, 25-30, ≥30 kg/m2) and gender-specific tertiles of WC. The primary endpoint was cardiovascular death, myocardial infarction or recurrent ischaemia.Patients with BMI ≥30 kg/m2 had a significantly lower risk of the primary endpoint than those with BMI <25 kg/m(2) (HR 0.64; 95% CI 0.51 to 0.81, p<0.0001) at 30 days. However, after the 30-day acute phase, landmark analysis from 30 days to 1 year showed no difference in risk between BMI groups (HR 1.09; 95% CI 0.92 to 1.29, p=0.34). WC tertiles demonstrated a similar relationship. When BMI groups were stratified by WC there was a trend towards more adverse outcomes in higher WC groups among those in lower BMI groups. The group with the lowest BMI and highest WC had the highest risk (HR 2.8; 95% CI 0.93 to 8.3; p=0.067).Obesity is associated with more favourable short-term outcomes after ACS. However, in the longer term the obesity paradox is no longer present and may reverse. Those with WC out of proportion to BMI suggestive of significant central adiposity may be at highest risk following ACS.

TITLE: Oral prednisone use and risk of keratinocyte carcinoma in non-transplant population. The VATTC trial.ABSTRACT: Glucorticosteroids (GC) are potent anti-inflammatory medications with immunosuppressive property. Few retrospective studies have reported the increased risk of development of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) associated with GC use.We aimed to assess the effect of oral GC use on the risk of BCC and SCC using prospective data.We analysed data from the Veterans Affairs Topical Tretinoin Chemoprevention Trial, which followed up patients from 1998 to 2004. Exposure to oral GCs was defined as (1) use of any oral GCs at any point during follow-up and (2) use of GCs for a month or longer. Outcome was occurrence of new BCC or SCC. Cox proportional hazard models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs).Among the 1051 study participants, 148 patients (14%) had prednisone prescription filled during study period, and 63 (6%) used prednisone for over a month. A total of 472 patients (45%) developed at least one BCC during study: 394 (44%) among non-users of prednisone and 78 (53%) among any time users. The total number of new SCC was 309 (29%): 258 (29%) among non-users of prednisone and 51 (34%) among users. Among any time prednisone users, the adjusted HR was 1.11 (95% CI, 0.87-1.42) for BCC, and 1.05 (95% CI, 0.76-1.45) for SCC. Among those who used prednisone for 30 or more days, the HR was 1.26 (95% CI, 0.90-1.78) for BCC, and 1.03 (95% CI, 0.66-1.60) for SCC.This study does not support the existence of association between use of oral GCs and risk of BCC or SCC.

TITLE: Carotid intima-media thickness, electrocardiographic left ventricular hypertrophy, and incidence of intracerebral hemorrhage.ABSTRACT: Carotid intima-media thickness and electrocardiographic left ventricular hypertrophy are 2 subclinical cardiovascular disease measures associated with increased risk of total and ischemic strokes. Increased intima-media thickness and electrocardiographic left ventricular hypertrophy also may reflect end-organ hypertensive effects. Information is scant on the associations of these subclinical measures with intracerebral hemorrhage (ICH). We hypothesized that greater carotid intima-media thickness and the presence of electrocardiographic left ventricular hypertrophy would be independently associated with increased ICH incidence.Among 18,155 participants initially free of stroke in the Atherosclerosis Risk in Communities Study (ARIC) and the Cardiovascular Health Study (CHS), we assessed carotid intima-media thickness, carotid plaque, and electrocardiographic left ventricular hypertrophy. Over a median of 18 years of follow-up, 162 incident ICH events occurred.After adjustment for other ICH risk factors, carotid intima-media thickness was associated positively with incidence of ICH in both ARIC and CHS. The risk was lowest in study-specific Quartile 1, elevated 1.6- to 2.6-fold in Quartiles 2 to 3, and elevated 2.5 to 3.7-fold in Quartile 4 (P<0.05 for both studies). In CHS, having a carotid plaque was associated with a 2-fold (95% CI, 1.1-3.4) greater ICH risk than having no plaque, but only 1.2-fold (95% CI, 0.76-2.0) greater ICH risk in ARIC. Electrocardiographic left ventricular hypertrophy carried a hazard ratio of ICH of 1.7 (95% CI, 0.77-3.7) in CHS and 2.8 (95% CI, 1.2-6.4) in ARIC.Our data suggest that people with carotid atherosclerosis and possibly left ventricular hypertrophy are at increased risk not only of ischemic stroke, but also of ICH.

TITLE: Assessing food appeal and desire to eat: the effects of portion size & energy density.ABSTRACT: Visual presentation of food provides considerable information such as its potential for palatability and availability, both of which can impact eating behavior.We investigated the subjective ratings for food appeal and desire to eat when exposed to food pictures in a fed sample (n=129) using the computer paradigm ImageRate. Food appeal and desire to eat were analyzed for the effects of food group, portion size and energy density of the foods presented as well as by participant characteristics.Food appeal ratings were significantly higher than those for desire to eat (57.9±11.6 v. 44.7±18.0; p<0.05). Body mass index was positively correlated to desire to eat (r=0.20; p<0.05), but not food appeal. Food category analyses revealed that fruit was the highest rated food category for both appeal and desire, followed by discretionary foods. Additionally, overweight individuals reported higher ratings of desire to eat large portions of food compared to smaller portions (p<0.001), although these effects were relatively small. Energy density of the foods was inversely correlated with ratings for both appeal and desire (r's=-0.27; p's<0.01).Results support the hypothesis that individuals differentiate between food appeal and desire to eat foods when assessing these ratings using the same type of metric. Additionally, relations among food appeal and desire to eat ratings and body mass show overweight individuals could be more responsive to visual foods cues in a manner that contributes to obesity.

TITLE: Efficacy and tolerability of a 20-mg dose of methylphenidate for the treatment of daytime sleepiness in adult patients with myotonic dystrophy type 1: a 2-center, randomized, double-blind, placebo-controlled, 3-week crossover trial.ABSTRACT: Despite the fact that excessive daytime sleepiness (EDS) is one of the most common manifestations in patients with myotonic dystrophy type 1 (DM1), no treatment is yet available. Methylphenidate is being studied for prospective use in the treatment of EDS.The aim of this investigator-initiated study was to evaluate the efficacy and tolerability of a single 20-mg morning dose of methylphenidate for the treatment of EDS in adults with DM1.This randomized, double-blind, placebo-controlled, 3-week crossover trial was conducted at 2 sites in Quebec. French-Canadian patients with DM1 with an Epworth Sleepiness Scale score ≥10 were invited to participate in this crossover trial of 20 mg/d of methylphenidate versus placebo, with 3 weeks in each arm of the study separated by a 2-week washout period. The primary efficacy end points were the Daytime Sleepiness Scale and the Epworth Sleepiness Scale at week 3. Secondary end points included the energy/vitality scale of the RAND 36-Item Health Survey, the Profile of Mood States questionnaire, and the mean sleep latency test. Assessment of tolerability profile included a physical examination, measurement of blood pressure, standard 12-lead ECG, and laboratory tests. Adverse event assessments were recorded based on patient reporting at each visit on clinical report forms.In a total of 24 patients (12 men, 12 women; mean [SD] age, 46 [13] years), 17 completed the study. Treatment with methylphenidate showed a significant change in median scores on the Daytime Sleepiness Scale (-3.0 vs -0.5; P = 0.003) and the Epworth Sleepiness Scale (-3.0 vs -1.5; P = 0.039). The Profile of Mood States and the energy/vitality scale from the RAND 36-Item Health Survey showed no significant changes. Likewise, there was no significant change in mean sleep latency test results. One patient died during the trial, but the autopsy results eliminated methylphenidate as cause of death. Three patients discontinued methylphenidate due to treatment-emergent adverse events (1, diarrhea; 2, nervousness and irritability). Loss of appetite, nausea, and palpitations were the most common adverse events reported by more patients treated with methylphenidate than those receiving placebo.A single 20-mg dose of methylphenidate significantly reduced daytime sleepiness in this small selected population of patients with DM1.

TITLE: Low-Sodium Versus Standard-Sodium Peritoneal Dialysis Solution in Hypertensive Patients: A Randomized Controlled Trial.ABSTRACT: Peritoneal dialysis (PD) solutions with reduced sodium content may have advantages for hypertensive patients; however, they have lower osmolarity and solvent drag, so the achieved Kt/Vurea may be lower. Furthermore, the increased transperitoneal membrane sodium gradient can influence sodium balance with consequences for blood pressure (BP) control.Prospective, randomized, double-blind clinical trial to prove the noninferiority of total weekly Kt/Vurea with low-sodium versus standard-sodium PD solution, with the lower confidence limit above the clinically accepted difference of -0.5.Hypertensive patients (≥ 1 antihypertensive drug, including diuretics, or office systolic BP ≥ 130 mmHg) on continuous ambulatory PD therapy from 17 sites.108 patients were randomly assigned (1:1) to 6-month treatments with either low-sodium (125 mmol/L of sodium; 1.5%, 2.3%, or 4.25% glucose; osmolarity, 338-491 mOsm/L) or standard-sodium (134 mmol/L of sodium; 1.5%, 2.3%, or 4.25% glucose; osmolarity, 356-509 mOsm/L) PD solution.Primary end point: weekly total Kt/Vurea; secondary outcomes: BP control, safety, and tolerability.Total Kt/Vurea was determined from 24-hour dialysate and urine collection; BP, by office measurement.Total Kt/Vurea after 12 weeks was 2.53 ± 0.89 in the low-sodium group (n = 40) and 2.97 ± 1.58 in the control group (n = 42). The noninferiority of total Kt/Vurea could not be confirmed. There was no difference for peritoneal Kt/Vurea (1.70 ± 0.38 with low sodium, 1.77 ± 0.44 with standard sodium), but there was a difference in renal Kt/Vurea (0.83 ± 0.80 with low sodium, 1.20 ± 1.54 with standard sodium). Mean daily sodium removal with dialysate at week 12 was 1.188 g higher in the low-sodium group (P < 0.001). BP changed marginally with standard-sodium solution, but decreased with low-sodium PD solution, resulting in less antihypertensive medication.Broader variability of study population than anticipated, particularly regarding residual kidney function.The noninferiority of the low-sodium PD solution for total Kt/Vurea could not be proved; however, it showed beneficial clinical effects on sodium removal and BP.

TITLE: The impact of access blood flow surveillance on reduction of thrombosis in native arteriovenous fistula: a randomized clinical trial.ABSTRACT: The usefulness of access blood flow (QA) measurement is an ongoing controversy. Although all vascular access (VA) clinical guidelines recommend monitoring and surveillance protocols to prevent VA thrombosis, randomized clinical trials (RCTs) have failed to consistently show the benefits of QA-based surveillance protocols. We present a 3-year follow-up multicenter, prospective, open-label, controlled RCT, to evaluate the usefulness of QA measurement using Doppler ultrasound (DU) and ultrasound dilution method (UDM), in a prevalent hemodialysis population with native arteriovenous fistula (AVF).Classical monitoring and surveillance methods are applied in all patients, the control group (n = 98) and the QA group (n = 98). Besides this, DU and UDM are performed in the QA group every three months. When QA is under 500 ml/min or there is a >25% decrease in QA the patient goes for fistulography, surgery or close clinical/surveillance observation. Thrombosis rate, assisted primary patency rate, primary patency rate and secondary patency rate are measured.After one-year follow-up we found a significant reduction in thrombosis rate (0.022 thrombosis/patient/year at risk in the QA group compared to 0.099 thrombosis/patient/year at risk in the control group [p = 0.030]). Assisted primary patency rate was significantly higher in the QA group than in control AVF (hazard ratio [HR] 0.23, 95% confidence interval [CI] 0.05-0.99; p = 0.030). In the QA group, the numbers unddergoing angioplasty and surgery were higher but with no significant difference in non-assisted primary patency rate (HR 1.41, 95% CI 0.72-2.84; p = 0.293). There was a non-significant improvement in secondary patency rate in the QA group (HR 0.510, 95% CI 0.17-1.50; p = 0.207).The measurement of QA combining DU and UDM shows a reduction in thrombosis rate and an increased assisted primary patency rate in AVF after one-year follow-up.ClinicalTrials.gov Identifier: NCT02111655.

TITLE: BRAzil magnesium (BRAMAG) trial: a double-masked randomized clinical trial of oral magnesium supplementation in pregnancy.ABSTRACT: There is conflicting evidence about the role of oral magnesium supplementation in the prevention of preterm birth and related adverse outcomes. The objective of this study was to compare magnesium citrate with placebo in the prevention of adverse perinatal and maternal outcomes among women at higher risk.This multicenter, double-masked, placebo-controlled randomized superiority clinical trial compared oral magnesium citrate 300 mg to matched placebo, from 12 to 20 weeks' gestation until delivery. This trial was completed in three centers in northeastern Brazil. Eligible women were those with a singleton pregnancy and ≥ 1 risk factor, such as prior preterm birth or preeclampsia, or current chronic hypertension or pre-pregnancy diabetes mellitus, age > 35 years or elevated body mass index. The primary perinatal composite outcome comprised preterm birth < 37 weeks' gestation, stillbirth > 20 weeks, neonatal death or NICU admission < 28 days after birth, or small for gestational age birthweight < 3rd percentile. The co-primary maternal composite outcome comprised preeclampsia or eclampsia < 37 weeks, severe gestational hypertension < 37 weeks, placental abruption, or maternal stroke or death during pregnancy or ≤ 7 days after delivery.Analyses comprised 407 women who received magnesium citrate and 422 who received placebo. The perinatal composite outcome occurred among 75 (18.4%) in the magnesium arm and 76 (18.0%) in the placebo group - an adjusted odds ratio (aOR) of 1.10 (95% CI 0.72-1.68). The maternal composite outcome occurred among 49 (12.0%) women in the magnesium arm and 41 women (9.7%) in the placebo group - an aOR of 1.29 (95% CI 0.83-2.00).Oral magnesium citrate supplementation did not appear to reduce adverse perinatal or maternal outcomes in high-risk singleton pregnancies.ClinicalTrials.gov NCT02032186, registered January 9, 2014.

TITLE: FTY720 versus MMF with cyclosporine in de novo renal transplantation: a 1-year, randomized controlled trial in Europe and Australasia.ABSTRACT: FTY720 is a novel immunomodulator investigated in de novo renal transplantation and other therapeutic areas including multiple sclerosis. This 1-year multicenter, randomized, phase III study in 668 de novo renal transplant patients compared FTY720 2.5 mg plus full-dose cyclosporine (FDC) or FTY720 5.0 mg plus reduced-dose cyclosporine (RDC), with mycophenolate mofetil (MMF) plus FDC. The primary efficacy endpoint was the composite incidence of first treated biopsy-proven acute rejection (BPAR), graft loss, death or premature study discontinuation at month 12. Primary efficacy with FTY720 2.5 mg and MMF (32.4% and 30.2%; p = NS), plus mortality and BPAR incidence, were comparable. Patients receiving FTY720 5.0 mg plus RDC were discontinued from treatment due to increased risk of acute rejection (primary endpoint incidence 47.3%). FTY720 was associated with lower creatinine clearance (month 12: 53.1, 56.0 vs. 65.1 mL/min; p < 0.001) and more macular edema cases (2.2% and 1.3% vs. 0%), whereas cytomegalovirus infections were higher with MMF (6.2% and 10.6% vs. 18.1% p < 0.0001 and p = 0.0139, respectively). FTY720 2.5 mg provided comparable rejection prophylaxis over 12 months versus MMF; however, FTY720 5.0 mg did not support a 50% reduction in cyclosporine exposure. The cause of macular edema cases and lower creatinine clearance with FTY720 in de novo transplantation needs further investigation.

TITLE: Prospective multicenter study of quality of life before and after lower extremity vein bypass in 1404 patients with critical limb ischemia.ABSTRACT: Patients with critical limb ischemia (CLI) have multiple comorbidities and limited life spans. The ability of infrainguinal vein bypass to improve quality of life (QoL) in patients with CLI has therefore been questioned. Prospective preoperative and postoperative QoL data for patients undergoing lower extremity vein bypass for CLI are presented.A validated, disease-specific QoL questionnaire (VascuQoL) with activity, symptom, pain, emotional, and social domains and responses scored 1 (lowest QoL) to 7 (best QoL) was administered before surgery and at 3 and 12 months after lower extremity vein bypass for CLI. Changes in QoL at 3 and 12 months after lower extremity vein bypass and multiple predetermined variables potentially influencing QoL after lower extremity vein bypass were analyzed to determine the effect of lower extremity vein bypass on QoL in CLI patients.A total of 1404 patients had lower extremity vein bypass for CLI at 83 centers in the United States and Canada as part of the PREVENT III clinical trial. Surveys were completed in 1296 patients at baseline, 862 patients at 3 months, and 732 patients at 12 months. The global QoL score (mean +/- SD) was 2.8 +/- 1.1 at baseline and was 4.7 +/- 1.4 and 5.1 +/- 1.4 at 3 and 12 months, respectively. Mean changes from baseline at 3 and 12 months were statistically significant (P < .0001). Improved QoL scores extended across all domains. Diabetes and the development of graft-related events were associated with decreased improvement in QoL scores, though the mean relative change from baseline remained positive.Patients with CLI have a low QoL at baseline that is improved at 3 and 12 months after lower extremity vein bypass. QoL improvements are lower in diabetic patients and those who develop graft-related events. Successful revascularization can be expected to improve QoL in patients with CLI, with benefits that are sustained to at least 1 year.

TITLE: Randomized phase II trial of gemcitabine plus weekly versus three-weekly paclitaxel in previously untreated advanced non-small-cell lung cancer.ABSTRACT: Gemcitabine and paclitaxel (Taxol) each provides an efficacious non-platinum option for the treatment of advanced non-small-cell lung cancer (NSCLC), but the optimal dosage and schedule of the two agents used in combination are not well defined.Previously untreated patients with advanced NSCLC were randomized to receive gemcitabine-paclitaxel on a traditional three-weekly schedule (Arm A) or a novel weekly schedule (Arm B) as follows-Arm A (three-weekly): gemcitabine 1000 mg/m2 infused>30 min on days 1 and 8 and paclitaxel 200 mg/m2 infused>3 h on day 1 of a 21-day cycle or Arm B (weekly): gemcitabine 1000 mg/m2 infused>30 min and paclitaxel 100 mg/m2 infused>1 h, both administered on days 1 and 8 of a 21-day cycle.One hundred patients received at least one dose of treatment. The weekly schedule, Arm B, was more efficacious and less hematologically toxic than Arm A. Confirmed complete and partial response rates were 28.2% and 26.8%, respectively. Median survival was 10.3 months on Arm B and 7.9 months on Arm A (log-rank P=0.10); 1- and 2-year survival rates also favor Arm B: 42.0% versus 34.0% and 18.0% versus 6.0%. Progression-free survival was 5.8 versus 4.8 months, again favoring Arm B (log-rank P=0.06). There was a two-fold lower frequency of grade 3/4 hematologic events with Arm B as follows: neutropenia (16% versus 30%), thrombocytopenia (4% versus 8%), and anemia (2% versus 6%). One patient (2%) in each treatment group developed febrile neutropenia.In this trial, both schedules were efficacious and tolerable, although the weekly schedule resulted in improved survival and lower hematologic toxicity compared with a three-weekly schedule. The weekly schedule of gemcitabine-paclitaxel indicates an improved therapeutic index.

TITLE: Effect of various diuretic treatments on rosiglitazone-induced fluid retention.ABSTRACT: The efficacy of diuretics in the management of rosiglitazone (RSG)-induced fluid retention was evaluated in a multicenter, randomized, open-label, parallel-group, proof-of-concept study. Of 381 patients who had type 2 diabetes and were on treatment with sulfonylurea or sulfonylurea plus metformin, 260 (63% male, 37% female) showed evidence of volume expansion as defined by an absolute reduction in hematocrit (Hct) of > or =0.5% after 12 wk of rosiglitazone 4 mg twice daily. They were randomly assigned to five treatments for 7 d: (1) Continuation of RSG (RSG-C), (2) RSG + furosemide (RSG+FRUS), (3) RSG + hydrochlorothiazide (RSG+HCTZ), (4) RSG + spironolactone (RSG+SPIRO), and (5) discontinuation of RSG. The primary end point was change in Hct at day 7 of diuretic treatment phase, powered to compare each diuretic group and the RSG discontinuation with the control group of RSG-C, with adjustments for multiple testing. After 12 wk on RSG, Hct fell by mean of 2.92% (95% confidence interval [CI] -3.10 to -2.63%; P < 0.001) and extracellular fluid volume increased by 0.62 L/1.73 m(2) (95% CI 0.26 to 0.90 L/1.73 m(2); P < 0.001). After treatment, the RSG+SPIRO group only showed a mean increase in Hct of 0.24%. The estimated mean difference in Hct reduction was significant: 1.14% (95% CI 0.29 to 1.98%) for RSG+SPIRO (P = 0.004) and 0.87% (95% CI 0.03 to 1.71%) for RSG+HCTZ (P = 0.041) only. In additional analyses of between-diuretic treatment effects SPIRO induced a greater Hct rescue at 0.88% (95% CI -0.12 to 1.87%; P = 0.095) and extracellular fluid volume reduction of -0.75 L/1.73 m(2) (95% CI -1.52 to 0.03 L/1.73 m(2); P = 0.06) compared with FRUS, suggesting superiority in the management of RSG-associated fluid retention. There were no significant differences between SPIRO and HCTZ. These findings are consistent with peroxisome proliferator-activated receptor-gamma agonist activation of the epithelial sodium channel in the distal collecting duct, a site of action of SPIRO and a potential target for thiazide diuretics.

TITLE: Improving knowledge about mental illness through family-led education: the journey of hope.ABSTRACT: Families often do not receive the information that they need to care for their adult relatives with mental illness. This study examined the effectiveness of a family-led education intervention, the Journey of Hope, in improving participants' knowledge about mental illness and its treatment and decreasing their information needs.A total of 462 family members of adults with mental illness in Louisiana participated in the study; 231 were randomly assigned to immediate receipt of the Journey of Hope course (intervention group), and 231 were randomly assigned to a nine-month waiting list for the course (control group). Participants completed in-person, structured interviews assessing their knowledge of mental illness and problem-solving skills and their information needs at study enrollment (baseline), three months postbaseline, and eight months postbaseline.Random regression analyses indicate that at three and eight months postbaseline, compared with participants assigned to the control group, those in the intervention group reported greater knowledge gains (beta=.84, p< or =.01) and fewer needs for information on coping with positive symptoms (beta=-.63, p< or =.05), coping with negative symptoms (beta=-.80, p< or =.001), problem management (beta=-1.00, p< or =.001), basic facts about mental illness and its treatment (beta=-.73, p< or =.01), and community resources (beta=-.07, p< or =.05). These significant differences in knowledge and information needs were maintained over time and were significant even when controlling for participants' demographic characteristics and their relatives' clinical characteristics.Participation in family-led education interventions, such as the Journey of Hope, may provide families with the information they need to better cope with their relative's mental illness.

TITLE: A 1-year safety and efficacy study of duloxetine in patients with fibromyalgia.ABSTRACT: Evaluate the efficacy and safety of duloxetine at doses up to 120 mg once daily in patients with fibromyalgia.This was a phase 3, 60-week study, which included an 8-week open-label period followed by a 52-week, randomized, double-blind period. Patients received duloxetine 30 mg daily for 1 week and duloxetine 60 mg daily for 7 weeks and were then randomized to receive either 60 or 120 mg daily (1:2 ratio).Enrolled patients (N=350, 95.7% female) exhibited moderate disease symptoms at study entry (Brief Pain Inventory average pain=6.7, Clinical Global Impression of Severity=4.1, and Patient's Global Impression of Severity=4.1). Significant pain reduction in patients was observed during the open-label study phase. This pain reduction continued during the 52-week double-blind study phase, as demonstrated by additional mean decreases in the Brief Pain Inventory average pain score within both duloxetine groups. The most common (> or =15%) treatment-emergent adverse events (overall phase) were nausea, headache, insomnia, dizziness, constipation, and dry mouth. Seventy-four (21.1%) patients reported adverse events as a reason for discontinuation [most common (>1%) were insomnia, vomiting, diarrhea, dizziness, and nausea]. The mean change (SD) in sitting systolic blood pressure (mm Hg) was -0.1 (14.4), in sitting diastolic blood pressure was -0.2 (9.6), in sitting pulse rate was 1.9 (10.4) bpm, and in weight was 0.7 (4.3) kg.The profile of duloxetine for the long-term treatment of fibromyalgia was consistent with that seen in other indications for which the drug is currently marketed.

TITLE: Daclizumab versus antithymocyte globulin in high-immunological-risk renal transplant recipients.ABSTRACT: Nondepleting anti-CD25 monoclonal antibodies (daclizumab) and depleting polyclonal antithymocyte globulin (Thymoglobulin) both prevent acute rejection, but these therapies have not been directly compared in a high-risk, HLA-sensitized renal transplant population. We randomly assigned 227 patients, who were about to receive a kidney graft from a deceased donor, to either Thymoglobulin or daclizumab if they met one of the following risk factors: current panel reactive antibodies (PRA) >30%; peak PRA >50%; loss of a first kidney graft from rejection within 2 yr of transplantation; or two or three previous grafts. Maintenance immunosuppression comprised tacrolimus, mycophenolate mofetil, and steroids. Compared with the daclizumab group, patients treated with Thymoglobulin had a lower incidence of both biopsy-proven acute rejection (15.0% versus 27.2%; P = 0.016) and steroid-resistant rejection (2.7% versus 14.9%; P = 0.002) at one year. One-year graft and patient survival rates were similar between the two groups. In a comparison of rejectors and nonrejectors, overall graft survival was significantly higher in the rejection-free group (87.2% versus 75.0%; P = 0.037). In conclusion, among high-immunological-risk renal transplant recipients, Thymoglobulin is superior to daclizumab for the prevention of biopsy-proven acute rejection, but there is no significant benefit to one-year graft or patient survival.

TITLE: Survival benefit with erlotinib maintenance therapy in patients with advanced non-small-cell lung cancer (NSCLC) according to response to first-line chemotherapy.ABSTRACT: In the placebo-controlled phase III SATURN study, maintenance erlotinib after first-line chemotherapy demonstrated significantly prolonged progression-free survival (PFS) and overall survival (OS) in the overall study population of patients with advanced non-small-cell lung cancer (NSCLC).After four cycles of platinum-based doublet chemotherapy, patients without progressive disease (PD) were randomised to erlotinib (150 mg/day) or placebo until PD or unacceptable toxicity. In this pre-planned analysis, data are assessed according to response to first-line chemotherapy (complete/partial response [CR/PR] or stable disease [SD]).Following first-line chemotherapy, 889 non-PD patients were included in the intention-to-treat population (55% SD; 44% CR/PR; <1% unknown response). Erlotinib maintenance therapy significantly prolonged PFS in both the SD (hazard ratio [HR] = 0.68; P < 0.0001) and CR/PR (HR = 0.74; P = 0.0059) groups, while OS was significantly prolonged in the SD group only (HR = 0.72; P = 0.0019). The erlotinib-related OS benefit in the SD group remained significant across subgroups, irrespective of tumour histology and/or EGFR mutation status. The incidence of adverse events was similar in the SD group and the overall population, and erlotinib treatment did not negatively impact quality of life.Patients with advanced NSCLC and SD following first-line platinum-based doublet chemotherapy derive a significant OS benefit from maintenance erlotinib therapy.

TITLE: Efficient implementation of patient-specific simulated rehearsal for the carotid artery stenting procedure: part-task rehearsal.ABSTRACT: Patient-specific simulated rehearsal (PsR) is a technological advance within the domain of endovascular virtual reality (VR) simulation. It allows incorporation of patient-specific computed tomography Digital Imaging and Communications in Medicine (CT DICOM) data into the simulation and subsequent rehearsal of real patient cases. This study aimed to evaluate whether a part-task rehearsal (PTr) of a carotid artery stenting procedure (CAS) on a VR simulator is as effective as a full-task (FTr) preoperative run through.Medical trainees were trained in the CAS procedure and randomised to a PTr or FTr of a challenging CAS case (Type-II arch). PTr consisted of 30 min of repeated catheterisations of the common carotid artery (CCA). Thereafter, both groups performed the CAS procedure in a fully functional simulated operating suite (SOS) with an interventional team. Technical performances were assessed using simulator-based metrics and expert ratings. Other aspects of performance were assessed using the Non-Technical Skills for Surgeons (NOTSS) scoring.Twenty trainees were evenly randomised to either PTr or FTr. No differences in performance were seen except for the total time the embolic protection device (EPD) was deployed (9.4 min for the PT vs. 8.1 min for the FT, p = 0.02). Total time (26.3 vs. 25.5 min, p = 0.94), fluoroscopy time (15.8 vs. 14.4 min, p = 0.68), number of roadmaps (10.5 vs. 11.0, p = 0.54), amount of contrast (53.5 vs. 58.0 ml, p = 0.33), time to deploy the EPD (0.9 vs. 0.8 min, p = 0.31) and time to catheterise the CCA (9.2 vs. 8.9 min, p = 0.94) were similar. Qualitative performances as measured by expert ratings (score 24 vs. 24, p = 0.49) and NOTSS (p > 0.05 for all categories) were also comparable.Part- and full-task rehearsals are equally effective with respect to the operative performance of a simulated CAS intervention. This finding makes a patient-specific rehearsal more efficient and may increase the feasibility of implementation of this technology into medical practice.

TITLE: Gambling and adverse life events among urban adolescents.ABSTRACT: This study explored the cross sectional association between adverse life events and gambling in a sample of 515 urban adolescents (average age 17, 55% male, 88% African American). Approximately half of the sample had gambled in the past year (51%); 78% of the gamblers gambled monthly and 39% had a gambling-related problem. On the other hand, 88% of the sample had experienced at least one life event in the past year, and those experiencing events tended to live in more disadvantaged neighborhoods. The mere acknowledgement of experiencing a stressful life event in the past year (yes/no) was not associated with an increase in odds of being a gambler, with gambling more frequently, or with having a gambling problem. However, when the context of the event was considered, an association was found between directly experiencing threatening and deviant/violent types of events and frequent gambling (OR > 2). Additionally, the probability of being a gambler increased as the number of events experienced increased (aOR = 1.07, 95% CI = 1.01, 1.13, P = 0.013), but problems among gamblers were not associated with the number of events experienced (aOR = 1.01, 95% CI = 0.92, 1.11, P = 0.876). During adolescence, life events appear to be connected more with the frequency of gambling rather than with problems related to gambling.

TITLE: Outcome comparison of 600- and 300-mg loading doses of clopidogrel in patients undergoing primary percutaneous coronary intervention for ST-segment elevation myocardial infarction: results from the ARMYDA-6 MI (Antiplatelet therapy for Reduction of MYocardial Damage during Angioplasty-Myocardial Infarction) randomized study.ABSTRACT: The purpose of this study was to compare 600- and 300-mg clopidogrel loading doses in patients with ST-segment elevation myocardial infarction (STEMI).Given the high thrombotic risk of patients with STEMI, greater platelet inhibition may improve outcome in those patients receiving percutaneous coronary intervention (PCI). Although observational data suggest that pretreatment with a 600-mg clopidogrel loading dose may be more effective than the 300-mg regimen in primary PCI, this hypothesis has never been tested in a randomized study.A total of 201 patients undergoing primary PCI for STEMI randomly received a 600-mg (n = 103) or 300-mg (n = 98) clopidogrel loading dose before the procedure. The primary endpoint was the evaluation of the infarct size, defined as the area under the curve of cardiac markers.Infarct size was significantly lower in the high-dose regimen: median creatine kinase-myocardial band 2,070 ng/ml (interquartile range [IQR]: 815 to 2,847 ng/ml) versus 3,049 ng/ml (IQR: 1,050 to 7,031 ng/ml) in the 300-mg group, p = 0.0001; troponin-I 255 ng/ml (IQR: 130 to 461 ng/ml) versus 380 ng/ml (IQR: 134 to 1,406 ng/ml), p < 0.0001. In the 600-mg arm, Thrombolysis In Myocardial Infarction flow grade <3 after PCI was less frequent (5.8% vs. 16.3%, p = 0.031), left ventricular ejection fraction at discharge was improved (52.1 ± 9.5% vs. 48.8 ± 11.3%, p = 0.026), 30-day major adverse cardiovascular events were fewer (5.8% vs. 15%, p = 0.049), and bleeding/entry site complications were not increased (secondary endpoints).In STEMI patients, pre-treatment with a 600-mg clopidogrel loading dose before primary PCI was associated with a reduction of the infarct size compared with a 300-mg loading dose, as well as with improvement of angiographic results, residual cardiac function, and 30-day major adverse cardiovascular events; further studies are warranted to evaluate impact of such strategy on survival.

TITLE: Integration of antiretroviral therapy with tuberculosis treatment.ABSTRACT: We previously reported that integrating antiretroviral therapy (ART) with tuberculosis treatment reduces mortality. However, the timing for the initiation of ART during tuberculosis treatment remains unresolved.We conducted a three-group, open-label, randomized, controlled trial in South Africa involving 642 ambulatory patients, all with tuberculosis (confirmed by a positive sputum smear for acid-fast bacilli), human immunodeficiency virus infection, and a CD4+ T-cell count of less than 500 per cubic millimeter. Findings in the earlier-ART group (ART initiated within 4 weeks after the start of tuberculosis treatment, 214 patients) and later-ART group (ART initiated during the first 4 weeks of the continuation phase of tuberculosis treatment, 215 patients) are presented here.At baseline, the median CD4+ T-cell count was 150 per cubic millimeter, and the median viral load was 161,000 copies per milliliter, with no significant differences between the two groups. The incidence rate of the acquired immunodeficiency syndrome (AIDS) or death was 6.9 cases per 100 person-years in the earlier-ART group (18 cases) as compared with 7.8 per 100 person-years in the later-ART group (19 cases) (incidence-rate ratio, 0.89; 95% confidence interval [CI], 0.44 to 1.79; P=0.73). However, among patients with CD4+ T-cell counts of less than 50 per cubic millimeter, the incidence rates of AIDS or death were 8.5 and 26.3 cases per 100 person-years, respectively (incidence-rate ratio, 0.32; 95% CI, 0.07 to 1.13; P=0.06). The incidence rates of the immune reconstitution inflammatory syndrome (IRIS) were 20.1 and 7.7 cases per 100 person-years, respectively (incidence-rate ratio, 2.62; 95% CI, 1.48 to 4.82; P<0.001). Adverse events requiring a switching of antiretroviral drugs occurred in 10 patients in the earlier-ART group and 1 patient in the later-ART group (P=0.006).Early initiation of ART in patients with CD4+ T-cell counts of less than 50 per cubic millimeter increased AIDS-free survival. Deferral of the initiation of ART to the first 4 weeks of the continuation phase of tuberculosis therapy in those with higher CD4+ T-cell counts reduced the risks of IRIS and other adverse events related to ART without increasing the risk of AIDS or death.

TITLE: Selective decontamination of the oral and digestive tract in surgical versus non-surgical patients in intensive care in a cluster-randomized trial.ABSTRACT: Selective digestive decontamination (SDD) and selective oropharyngeal decontamination (SOD) are effective in improving survival in patients under intensive care. In this study possible differential effects in surgical and non-surgical patients were investigated.This was a post hoc subgroup analysis of data from a cluster-randomized multicentre trial comparing three groups (SDD, SOD or standard care) to quantify effects among surgical and non-surgical patients. The primary study outcome was 28-day mortality rate. Duration of mechanical ventilation, duration of intensive care unit (ICU) and hospital length of stay, and bacteraemia rates were secondary outcomes.The subgroup analyses included a total of 2762 surgical and 3165 non-surgical patients. Compared with standard care, adjusted odds ratios (ORs) for mortality were comparable in SDD-treated surgical and non-surgical patients: 0·86 (95 per cent confidence interval 0·69 to 1·09; P = 0·220) and 0·85 (0·70 to 1·03; P = 0·095) respectively. However, duration of mechanical ventilation, ICU stay and hospital stay were significantly reduced in surgical patients who had SDD. SOD did not reduce mortality compared with standard treatment in surgical patients (adjusted OR 0·97, 0·77 to 1·22; P = 0·801); in non-surgical patients it reduced mortality (adjusted OR 0·77, 0·63 to 0·94; P = 0·009) by 16·6 per cent, representing an absolute mortality reduction of 5·5 per cent with number needed to treat of 18.Subgroup analysis found similar effects of SDD in reducing mortality in surgical and non-surgical ICU patients, whereas SOD reduced mortality only in non-surgical patients. The hypothesis-generating findings mandate investigation into mechanisms between different ICU populations.

TITLE: Usefulness of minimum stent cross sectional area as a predictor of angiographic restenosis after primary percutaneous coronary intervention in acute myocardial infarction (from the HORIZONS-AMI Trial IVUS substudy).ABSTRACT: HORIZONS-AMI was a prospective dual-arm randomized trial of different antithrombotic regimens and stent types in patients with ST-segment elevation myocardial infarction. A formal intravascular ultrasound (IVUS) substudy enrolled 464 patients with baseline and 13-month follow-up at 36 centers. Of them, 318 patients with 355 lesions were evaluated for this study. Angiographic restenosis occurred in 45 of 355 lesions (12.7%). Bare-metal stent use (45.5% vs 21.2%, p <0.001) and diabetes mellitus (29.5% vs 10.9%, p <0.001) were more prevalent in patients with versus without restenosis. Postprocedure IVUS minimum lumen area (5.6 mm(2), 5.0 to 6.1, vs 6.7 mm(2), 6.5 to 6.9, p <0.001), minimum stent area (5.7 mm(2), 5.1 to 6.3, vs 6.9 mm(2), 6.6 to 7.1, p <0.001), and reference average lumen area (7.7 mm(2), 6.8 to 8.6, vs 9.7 mm(2), 9.3 to 10.1, p <0.001) were smaller in restenotic versus nonrestenotic lesions. By multivariable analysis, minimum stent area was an independent predictor of angiographic restenosis (odds ratio 0.75, 95% confidence interval 0.61 to 0.93, p = 0.009) in addition to diabetes, bare-metal stent use, and longer stent length. Attenuated plaque behind the stent struts had a trend to predict less binary restenosis (p = 0.07). In conclusion, a smaller IVUS minimum stent area was an independent predictor of angiographic restenosis after primary percutaneous intervention in patients with ST-segment elevation myocardial infarction, similar to patients with stable coronary artery disease.

TITLE: HIV-1 protease inhibitors and clinical malaria: a secondary analysis of the AIDS Clinical Trials Group A5208 study.ABSTRACT: HIV-1 protease inhibitors (PIs) have antimalarial activity in vitro and in murine models. The potential beneficial effect of HIV-1 PIs on malaria has not been studied in clinical settings. We used data from Adult AIDS Clinical Trials Group A5208 sites where malaria is endemic to compare the incidence of clinically diagnosed malaria among HIV-infected adult women randomized to either lopinavir/ritonavir (LPV/r)-based antiretroviral therapy (ART) or to nevirapine (NVP)-based ART. We calculated hazard ratios and 95% confidence intervals. We conducted a recurrent events analysis that included both first and second clinical malarial episodes and also conducted analyses to assess the sensitivity of results to outcome misclassification. Among the 445 women in this analysis, 137 (31%) received a clinical diagnosis of malaria at least once during follow-up. Of these 137, 72 (53%) were randomized to LPV/r-based ART. Assignment to the LPV/r treatment group (n = 226) was not consistent with a large decrease in the hazard of first clinical malarial episode (hazard ratio = 1.11 [0.79 to 1.56]). The results were similar in the recurrent events analysis. Sensitivity analyses indicated the results were robust to reasonable levels of outcome misclassification. In this study, the treatment with LPV/r compared to NVP had no apparent beneficial effect on the incidence of clinical malaria among HIV-infected adult women. Additional research concerning the effects of PI-based therapy on the incidence of malaria diagnosed by more specific criteria and among groups at a higher risk for severe disease is warranted.

TITLE: Antiandrogen monotherapy in patients with localized or locally advanced prostate cancer: final results from the bicalutamide Early Prostate Cancer programme at a median follow-up of 9.7 years.ABSTRACT: To evaluate the efficacy and tolerability of bicalutamide 150 mg once-daily as immediate hormonal therapy in patients with prostate cancer or as adjuvant to radical prostatectomy or radiotherapy.In all, 8113 patients with localized (T1-2, N0/Nx) or locally advanced (T3-4, any N; or any T, N+) prostate cancer (all M0) were enrolled in three complementary, double-blind, placebo-controlled trials. Patients were randomized to receive standard care plus either oral bicalutamide 150 mg once-daily or oral placebo. Primary endpoints were progression-free survival (PFS) and overall survival (OS). Data were collated from individual trials and evaluated in a combined analysis.Overall, at a median follow-up of 9.7 years, bicalutamide significantly improved PFS (hazard ratio 0.85, 95% confidence interval 0.79-0.91; P= 0.001). Compared with placebo there was no difference in OS (hazard ratio 1.01, P= 0.77). Patients who derived benefit from bicalutamide in terms of PFS were those with locally advanced disease, with OS significantly favouring bicalutamide in patients with locally advanced disease undergoing radiotherapy (P= 0.031). Patients with localized disease showed no clinically or statistically significant improvements in PFS; there was a survival trend in favour of placebo in patients with localized disease undergoing watchful waiting (P= 0.054). The overall tolerability of bicalutamide was consistent with previous analyses, with breast pain (73.7%) and gynaecomastia (68.8%) the most frequently reported adverse events in patients randomized to bicalutamide.Bicalutamide 150 mg, either as monotherapy or adjuvant to standard care, improved PFS in patients with locally advanced prostate cancer, but not in patients with localized disease. A pre-planned subset analysis showed a benefit for OS in patients with locally advanced disease undergoing radiotherapy. Bicalutamide 150 mg might represent an alternative for patients with locally advanced prostate cancer considering androgen-deprivation therapy.

TITLE: Comparison of late results of percutaneous coronary intervention among stable patients ≤65 versus >65 years of age with an occluded infarct related artery (from the Occluded Artery Trial).ABSTRACT: Although opening an occluded infarct-related artery >24 hours after myocardial infarction in stable patients in the Occluded Artery Trial (OAT) did not reduce events over 7 years, there was a suggestion that the effect of treatment might differ by patient age. Baseline characteristics and outcomes by treatment with percutaneous coronary intervention (PCI) versus optimal medical therapy alone were compared by prespecified stratification at age 65 years. A p value <0.01 was prespecified as significant for OAT secondary analyses. The primary outcome was death, myocardial infarction, or New York Heart Association class IV heart failure. Patients aged >65 years (n = 641) were more likely to be female, to be nonsmokers, and to have hypertension, lower estimated glomerular filtration rates, and multivessel disease compared to younger patients (aged ≤65 years, n = 1,560) (p <0.001). There was no significant observed interaction between treatment assignment and age for the primary outcome after adjustment (p = 0.10), and there was no difference between PCI and optimal medical therapy observed in either age group. At 7-year follow-up, younger patients tended to have angina more often compared to the older group (hazard ratio 1.21, 99% confidence interval 1.00 to 1.46, p = 0.01). The 7-year composite primary outcome was more common in older patients (p <0.001), and age remained significant after covariate adjustment (hazard ratio 1.42, 99% confidence interval 1.09 to 1.84). The rate of early PCI complications was low in the 2 age groups. The trend toward a differential effect of PCI in the young versus the old for the primary outcome was likely driven by measured and unmeasured confounders and by chance. PCI reduces angina to a similar degree in the young and old. In conclusion, there is no indication for routine PCI to open a persistently occluded infarct-related artery in stable patients after myocardial infarction, regardless of age.

TITLE: Six-month versus 12-month dual antiplatelet therapy after implantation of drug-eluting stents: the Efficacy of Xience/Promus Versus Cypher to Reduce Late Loss After Stenting (EXCELLENT) randomized, multicenter study.ABSTRACT: The optimal duration of dual antiplatelet therapy (DAPT) after implantation of drug-eluting coronary stents remains undetermined. We aimed to test whether 6-month DAPT would be noninferior to 12-month DAPT after implantation of drug-eluting stents.We randomly assigned 1443 patients undergoing implantation of drug-eluting stents to receive 6- or 12-month DAPT (in a 1:1 ratio). The primary end point was a target vessel failure, defined as the composite of cardiac death, myocardial infarction, or ischemia-driven target vessel revascularization at 12 months. Rates of target vessel failure at 12 months were 4.8% in the 6-month DAPT group and 4.3% in the 12-month DAPT group (the upper limit of 1-sided 95% confidence interval, 2.4%; P=0.001 for noninferiority with a predefined noninferiority margin of 4.0%). Although stent thrombosis tended to occur more frequently in the 6-month DAPT group than in the 12-month group (0.9% versus 0.1%; hazard ratio, 6.02; 95% confidence interval, 0.72-49.96; P=0.10), the risk of death or myocardial infarction did not differ in the 2 groups (2.4% versus 1.9%; hazard ratio, 1.21; 95% confidence interval, 0.60-2.47; P=0.58). In the prespecified subgroup analysis, target vessel failure occurred more frequently in the 6-month DAPT group than in the 12-month group (hazard ratio, 3.16; 95% confidence interval, 1.42-7.03; P=0.005) among diabetic patients.Six-month DAPT did not increase the risk of target vessel failure at 12 months after implantation of drug-eluting stents compared with 12-month DAPT. However, the noninferiority margin was wide, and the study was underpowered for death or myocardial infarction. Our results need to be confirmed in larger trials.URL: http://www.clinicaltrials.gov.

TITLE: Comparison of Lichtenstein and laparoscopic transabdominal preperitoneal repair of recurrent inguinal hernias.ABSTRACT: The aim of our study was the comparative analysis of the results of two surgical methods: tension-free repair by the Lichtenstein technique and laparoscopic transabdominal preperitoneal (TAPP) repair. In total 52 patients with recurrent inguinal hernia were randomly assigned to the two groups: Lichtenstein (28 patients) and TAPP (24 patients). Comparisons between these groups were done by several preoperative, intraoperative, and postoperative factors. For postoperative factors both short-term and long-term results were considered. Average operation time for Lichtenstein group was 59.6 +/- 9.9 minutes, compared with 64.4 +/- 8.4 minutes for TAPP patients (P = 0.068). In TAPP patients there was less pain in the postoperative period (P = 0.002) and fewer sick-leave days (13.4 +/- 1.7 versus 17.5 +/- 2.6 days; P < 0.001) and, correspondingly, faster recovery. In the Lichtenstein group a total of 4 postoperative complications (infection, hematoma, seroma, urinary retention) were observed, compared with 8 in the TAPP group (P = 0.19). Statistically significant difference was only by urinary retention (0 for Lichtenstein, 4 for TAPP; P = 0.039). There were no cases of hernia recurrence observed during the followup. Chronic pain developed in 5 patients from the Lichtenstein group (17.9%) and 2 patients from the TAPP group (8.3%; P = 0.28) more than 1 year after the operation; 4 Lichtenstein patients (14.3%) and 1 TAPP patient (4.2%; P = 0.23) more than 2 years after the operation; and 3 Lichtenstein patients (10.7%) and 1 TAPP patient (4.2%; P = 0.36) more than 3 years after the operation. For the treatment of recurrent inguinal hernias, which are developed after use of conventional (nonmesh) methods, the first choice should be given to the laparoscopic method, especially for young, physically active, nonobese patients, and if there are any contraindications for the laparoscopy, the Lichtenstein approach should be recommended.

TITLE: Effect of aliskiren on post-discharge outcomes among diabetic and non-diabetic patients hospitalized for heart failure: insights from the ASTRONAUT trial.ABSTRACT: The objective of the Aliskiren Trial on Acute Heart Failure Outcomes (ASTRONAUT) was to determine whether aliskiren, a direct renin inhibitor, would improve post-discharge outcomes in patients with hospitalization for heart failure (HHF) with reduced ejection fraction. Pre-specified subgroup analyses suggested potential heterogeneity in post-discharge outcomes with aliskiren in patients with and without baseline diabetes mellitus (DM).ASTRONAUT included 953 patients without DM (aliskiren 489; placebo 464) and 662 patients with DM (aliskiren 319; placebo 343) (as reported by study investigators). Study endpoints included the first occurrence of cardiovascular death or HHF within 6 and 12 months, all-cause death within 6 and 12 months, and change from baseline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) at 1, 6, and 12 months. Data regarding risk of hyperkalaemia, renal impairment, and hypotension, and changes in additional serum biomarkers were collected. The effect of aliskiren on cardiovascular death or HHF within 6 months (primary endpoint) did not significantly differ by baseline DM status (P = 0.08 for interaction), but reached statistical significance at 12 months (non-DM: HR: 0.80, 95% CI: 0.64-0.99; DM: HR: 1.16, 95% CI: 0.91-1.47; P = 0.03 for interaction). Risk of 12-month all-cause death with aliskiren significantly differed by the presence of baseline DM (non-DM: HR: 0.69, 95% CI: 0.50-0.94; DM: HR: 1.64, 95% CI: 1.15-2.33; P < 0.01 for interaction). Among non-diabetics, aliskiren significantly reduced NT-proBNP through 6 months and plasma troponin I and aldosterone through 12 months, as compared to placebo. Among diabetic patients, aliskiren reduced plasma troponin I and aldosterone relative to placebo through 1 month only. There was a trend towards differing risk of post-baseline potassium ≥6 mmol/L with aliskiren by underlying DM status (non-DM: HR: 1.17, 95% CI: 0.71-1.93; DM: HR: 2.39, 95% CI: 1.30-4.42; P = 0.07 for interaction).This pre-specified subgroup analysis from the ASTRONAUT trial generates the hypothesis that the addition of aliskiren to standard HHF therapy in non-diabetic patients is generally well-tolerated and improves post-discharge outcomes and biomarker profiles. In contrast, diabetic patients receiving aliskiren appear to have worse post-discharge outcomes. Future prospective investigations are needed to confirm potential benefits of renin inhibition in a large cohort of HHF patients without DM.

TITLE: Long-term Survival Outcomes of 'Low Risk' Ductal Carcinoma in situ from a Territory-wide Cancer Registry.ABSTRACT: The LORIS trial is an ongoing phase III clinical trial on low risk ductal carcinoma in situ (DCIS). DCIS patients aged ≥46 years with screen-detected low/intermediate nuclear grade were considered low risk and were randomised into surveillance or standard surgery. Here we review the 10-year territory-wide breast cancer registry database and evaluate the clinical outcomes of low versus high risk DCIS patients.This was a retrospective study of a prospectively maintained territory-wide breast cancer registry in Hong Kong.Between 1997 and 2006, 1391 DCIS patients were identified from the Hong Kong cancer registry breast cancer database. The mean age at diagnosis was 49.2 years (range 30-70). In total, 372 patients were classified as 'low risk', whereas the remaining 777 patients were classified as 'high risk'. After a median follow-up of 11.6 years, the 10-year overall breast cancer-specific survival of the entire DCIS cohort was 1136/1149 (98.9%). Overall breast cancer-specific survival of low risk DCIS was 99.5%, whereas that in high risk DCIS was 98.6% (Log-rank test, P = 0.208). Forty-six (12.4%) patients in the LORIS low risk group did not receive surgery, whereas 93 (12%) patients in the LORIS high risk group did not receive surgery. The 10-year breast cancer-specific survival in the non-operated low risk DCIS group was 97.8%; that in the non-operated high risk DCIS group was 96.7% (P = 1).Long-term survival of DCIS was excellent, especially in low risk DCIS, regardless of surgical treatment.

TITLE: Computerized clinical decision support during medication ordering for long-term care residents with renal insufficiency.ABSTRACT: OBJECTIVE To determine whether a computerized clinical decision support system providing patient-specific recommendations in real-time improves the quality of prescribing for long-term care residents with renal insufficiency. DESIGN Randomized trial within the long-stay units of a large long-term care facility. Randomization was within blocks by unit type. Alerts related to medication prescribing for residents with renal insufficiency were displayed to prescribers in the intervention units and hidden but tracked in control units. Measurement The proportions of final drug orders that were appropriate were compared between intervention and control units within alert categories: (1) recommended medication doses; (2) recommended administration frequencies; (3) recommendations to avoid the drug; (4) warnings of missing information. RESULTS The rates of alerts were nearly equal in the intervention and control units: 2.5 per 1,000 resident days in the intervention units and 2.4 in the control units. The proportions of dose alerts for which the final drug orders were appropriate were similar between the intervention and control units (relative risk 0.95, 95% confidence interval 0.83, 1.1) for the remaining alert categories significantly higher proportions of final drug orders were appropriate in the intervention units: relative risk 2.4 for maximum frequency (1.4, 4.4); 2.6 for drugs that should be avoided (1.4, 5.0); and 1.8 for alerts to acquire missing information (1.1, 3.4). Overall, final drug orders were appropriate significantly more often in the intervention units-relative risk 1.2 (1.0, 1.4). CONCLUSIONS Clinical decision support for physicians prescribing medications for long-term care residents with renal insufficiency can improve the quality of prescribing decisions.http://clinicaltrials.gov Identifier: NCT00599209.

TITLE: Effect of trimetazidine on quality of life in elderly patients with ischemic dilated cardiomyopathy.ABSTRACT: Elderly patients have an increased incidence of ischemic dilated cardiomyopathy, often related to diffuse coronary artery disease. Data have been cumulated to suggest that trimetazidine improves myocardial ischemia in patients with ischemic heart disease and improves left ventricular function in elderly patients with ischemic cardiomyopathy. The purpose of the present study was to assess the effects of trimetazidine in addition to standard cardiovascular therapy on left ventricular function and quality of life (QOL) parameters in elderly patients with ischemic heart disease and reduced left ventricular function.Patients were randomized to receive either trimetazidine (twice daily) or placebo (twice daily) in addition to standard therapy, and were evaluated at baseline and after 6 months.Forty-seven patients completed the study (40 male, seven female; mean [+/-SD] age 78+/-3.4 years). Demographic data were comparable between the two groups with respect to sex, age, and race. At 6 months there was a significant improvement in the number of angina episodes per week in the trimetazidine group (-2.3+/-1, P=0.023). The overall assessment of QOL by a visual analog scale showed an improvement in patients randomized to trimetazidine at 6 months (from 4.1+/-0.6 to 6.4+/-0.8, P<0.01) and no changes in patients randomized to placebo (from 4.3+/-0.7 to 4.2+/-0.9, P>0.05). Physical QOL, evaluated by a MacNew Quality of Life After Myocardial Infarction questionnaire (MacNewQLMI), improved in patients randomized to trimetazidine but not in those allocated to placebo (32%+/-5% vs. -1%+/-3%, P<0.01). Similar results were obtained on social QOL evaluated by MacNewQLMI with trimetazidine compared with placebo (39%+/-4% vs. -2%+/-5%, P<0.01).In elderly patients with ischemic heart disease and reduced ventricular function, trimetazidine improves clinical condition and QOL.

TITLE: Efficacy of gemfibrozil in the primary prevention of atrial fibrillation in a large randomized controlled trial.ABSTRACT: Peroxisome proliferator-activated receptor alpha (PPARalpha) activators reduce inflammation and oxidative stress. Inflammation plays an important role in the initiation and maintenance of atrial fibrillation (AF). It has been suggested that PPARalpha activators may have antiarrhythmic properties, but no clinical data exist. The objective of this study was to investigate whether the PPARalpha activator gemfibrozil prevents or delays the development of AF in patients with coronary heart disease.We retrospectively analyzed the electrocardiograms (ECGs) performed in the Veterans Affairs High-Density Lipoprotein Cholesterol Intervention Trial, a multicenter, randomized, double-blinded, secondary prevention trial of gemfibrozil and matching placebo. The ECGs were performed annually or biannually and when clinically indicated. Participants who were in AF on baseline ECG were excluded from the present analysis. Relative risk for AF was calculated from Cox regression with death as a competing risk factor.A total of 12,605 ECGs from 2,130 participants were interpreted (5.9 +/- 2.1 ECGs per participant, range 2-20). At baseline, the gemfibrozil (n = 1,070) and placebo (n = 1,060) groups were well matched. Mean age was 64.1 +/- 7.1 years. Over 4.4 +/- 1.5 years of follow-up, 123 (5.8%) participants developed new AF. There was no difference in AF incidence between the gemfibrozil and placebo groups (64/1,070 vs 59/1,060, respectively; P = .33). In Cox regression, the risk of AF was similar between the 2 study groups (hazard ratio 1.04, 95% CI 0.73-1.49, P = .82).In this post hoc analysis of a multicenter, double-blinded, randomized controlled trial, the PPARalpha activator gemfibrozil did not reduce the 4-year incidence of AF among men with coronary heart disease.

TITLE: Long-term outcome of endovascular treatment versus medical care for carotid artery stenosis in patients not suitable for surgery and randomised in the Carotid and Vertebral Artery Transluminal Angioplasty study (CAVATAS).ABSTRACT: Optimal treatment of carotid stenosis in patients not suitable for surgery is unclear. The Carotid and Vertebral Artery Transluminal Angioplasty study contained a trial comparing medical and endovascular treatment in patients not suitable for surgery.Forty patients were randomised to medical or endovascular treatment in equal numbers, and patients were followed up for up to 10 years. The primary outcome measure was defined as stroke or death during follow-up, analysed by intention-to-treat. Secondary analyses included disabling stroke, death, any stroke, any stroke or transient ischemic attack (TIA), all during follow-up.Baseline characteristics were similar. The risk of stroke, retinal infarction or death within 30 days of endovascular treatment was 5% (95% CI: 0.1-24.9%). By the study end, >50% of patients had suffered a recurrent TIA, stroke or died. One third of events were non-stroke deaths. Overall, there was no significant difference between medical and endovascular treatment in the primary outcome rate of stroke or death after randomisation (hazard ratio: 0.98, 95% CI: 0.39-2.48) or the rate of any stroke or TIA (hazard ratio: 1.43, 95% CI: 0.54-3.75).We failed to show superiority of endovascular treatment above medical care alone for carotid stenosis in a very small group of patients not suitable for surgical treatment. However, the trial randomised only 40 patients, and was therefore severely underpowered to detect clinically relevant treatment differences. Ongoing trials of carotid stenting will need to demonstrate improved safety and efficacy before endovascular treatment should enter routine practice.

TITLE: Safety and tolerability of duloxetine at 60 mg once daily in elderly patients with major depressive disorder.ABSTRACT: To compare the safety and tolerability profile of duloxetine versus placebo in elderly (> or = 65 years) patients with major depressive disorder (MDD).Patients were randomized (2:1) to duloxetine 60 mg/d (once daily) (n = 207) or placebo (n = 104) for 8 weeks. Safety and tolerability measures were analyzed in the total cohort of patients, as well as in subgroups defined by age and preexisting hypertension.Patients had a median age of 72 years (65-90 years). No deaths occurred in the study. Discontinuation rates due to adverse events were similar for duloxetine and placebo (9.7% vs 8.7%). Treatment-emergent dry mouth, nausea, and diarrhea occurred significantly (P < or = 0.05) more frequently with duloxetine compared with placebo. Changes in supine and standing blood pressure (BP) and pulse and in corrected QT (QTc) interval were not significantly different between duloxetine and placebo, except for change in orthostatic systolic BP (-2.45 vs 0.93 mm Hg; P = .017). Incidences of sustained elevation in BP and treatment-emergent orthostatic hypotension were similar for duloxetine compared with placebo (0.5% vs 1.0% and 15.6% vs 20.5%, respectively). The duloxetine group showed significant weight loss compared with the placebo group (-0.73 kg vs -0.13 kg; P = 0.009). Of 5 hepatic analytes, the only significant difference was an increase in alkaline phosphatase in duloxetine compared with placebo (P = 0.017); this difference was not considered clinically relevant. The incidence of 1 or more discontinuation-emergent adverse events was not significantly different between the duloxetine and placebo groups (17.3% vs 11.3%).This study suggests that duloxetine is safe and well tolerated in elderly patients with major depressive disorder.

TITLE: Functional impact of high clopidogrel maintenance dosing in patients undergoing elective percutaneous coronary interventions. Results of a randomized study.ABSTRACT: The currently recommended maintenance dose of clopidogrel is often associated with inadequate platelet inhibition, suggesting the need for a higher dose. The aim of this pilot study was to assess the functional impact of a high (150 mg/day) maintenance dose of clopidogrel in patients undergoing elective percutaneous coronary intervention (PCI). This is a prospective, randomized, platelet function study which was performed in elective PCI patients assigned to treatment with either a 75 mg (n = 20) or 150 mg (n = 20) daily maintenance dose of clopidogrel for 30 days; afterwards, all patients resumed standard dosing. Platelet aggregation was performed using light transmittance aggregometry following 20 microM and 5 microM adenosine diphosphate (ADP) stimuli 30 days after randomization and 30 days after resuming standard dosing. Patients treated with 150 mg/day clopidogrel had lower 20 microM ADP-induced platelet aggregation compared to patients on 75 mg/day (52.1 +/- 9% vs. 64.0 +/- 8%; p < 0.001; primary endpoint). The dose-dependent effect was confirmed by the absolute and relative increase in platelet aggregation after resuming standard dosing (p < 0.001). No changes were observed in patients randomized to standard dosing. Parallel findings were observed following 5 microM ADP stimuli for all assessments. A broad variability in clopidogrel-induced antiplatelet effects was observed irrespective of dosing. In conclusion, a 150 mg/day maintenance dose regimen of clopidogrel is associated with reduced platelet reactivity and enhanced platelet inhibition compared to that achieved with the currently recommended 75 mg/day in patients undergoing elective PCI.

TITLE: Tranexamic acid reduces perioperative blood loss in cervical laminoplasty: a prospective randomized study.ABSTRACT: A prospective randomized comparative study.To evaluate the effect of tranexamic acid (TXA) on decreasing perioperative blood loss in cervical laminoplasty, in which the surgical procedure is identical in all cases.TXA, an inhibitor of fibrinolysis, has proven to be effective in reducing perioperative blood loss in patients undergoing total hip and knee arthroplasty. However, only a limited number of well-controlled spinal surgery trials have been conducted due to heterogeneity in the performed surgical procedures.Forty consecutive patients with cervical compressive myelopathy were prospectively randomized into groups that received 15 mg/kg body weight of TXA or placebo intravenously before the skin incision was made. "French-door" cervical laminoplasty from C3 to C6 was performed for all patients by using a consistent procedure. Intraoperative and postoperative blood loss was compared between the groups. The surgery and follow-up were conducted at a single institution.There were no statistically significant differences between the TXA and control groups in terms of age, sex, body mass index, and operating time. Intraoperative blood loss in the TXA group (49.1 ± 30.6 mL) was not significantly different from that in the control group (63.4 ± 53.0 mL, P = 0.30). However, in the TXA group, postoperative blood loss during the first 16 hours was reduced by 37% as compared to the control group (132.0 ± 45.3 vs. 211.0 ± 41.5 mL; P < 0.01). The total blood loss (intraoperative plus postoperative blood loss during the first 40 hours) in the TXA group (264.1 ± 75.1 mL) was significantly lower than that in the control group (353.9 ± 60.8 mL, P < 0.01). No thromboembolic events or complications occurred in either group.TXA significantly reduced perioperative blood loss, primarily through a reduction in postoperative blood loss, in cervical laminoplasty.

TITLE: Misoprostol vaginal insert for successful labor induction: a randomized controlled trial.ABSTRACT: To compare three doses of misoprostol vaginal insert for successful labor induction measured by the proportion of vaginal deliveries within 24 hours.A total of 374 women with modified Bishop scores of 4 or lower before induction of labor were randomly assigned to receive misoprostol vaginal insert (MVI) 100 (n=118), MVI 150 (n=125), or MVI 200 (n=131) micrograms. The insert was removed for onset of active labor or adverse event. The primary outcome was proportion of vaginal deliveries within 24 hours. The comparison group was MVI 100. Safety was assessed by comparing rates of cesarean deliveries and adverse events.Twenty-four percent of women receiving MVI 200 failed to achieve vaginal delivery within 24 hours compared with 36.3% of those receiving MVI 100 (P=.057, relative risk [RR] 0.66, 95% confidence interval [CI] 0.42-1.04). Compared with MVI 100, MVI 200 reduced median time to vaginal delivery (1,181 compared with 1,744 minutes, P=.02) and need for oxytocin (48.9% compared with 70.9%, P<.001, RR 0.70, 95% CI 0.56-0.85). The cesarean rates for women assigned to MVI 200 and 100 were 22.9% (30/131) and 31.4% (37/118) (P=.15, RR 0.73, 95% CI 0.48-1.10). Misoprostol vaginal insert 200 was associated with an increased rate of tachysystole (41.2%) compared with MVI 100 (19.5%) (P<.001, RR 2.11, 95% CI 1.39-3.22).Compared with MVI 100, MVI 200 was associated with a significant reduction in time to vaginal delivery, but did not improve proportion with vaginal delivery by 24 hours.ClinicalTrials.gov, www.clinicaltrials.gov, NCT00828711.

TITLE: Reduced darunavir dose is as effective in maintaining HIV suppression as the standard dose in virologically suppressed HIV-infected patients: a randomized clinical trial.ABSTRACT: Maximizing ART efficiency is of growing interest. This study assessed the efficacy, safety, pharmacokinetics and economics of a darunavir dose-reduction strategy.This was a multicentre, randomized, open-label clinical trial in HIV-infected patients with plasma HIV-1 RNA <50 copies/mL while receiving triple ART including 800 mg of darunavir once daily. Participants were randomized to continue 800 mg of darunavir (DRV800) or to 600 mg of darunavir (DRV600), both once daily. Treatment failure was defined as two consecutive HIV-1 RNA determinations >50 copies/mL or discontinuation of study treatment by week 48. The study was registered at https://www.clinicaltrialsregister.eu (trial number 2011-006272-39).Fifty participants were allocated to each arm. The mean (SD) CD4+ T cell count at baseline was 562 (303) cells/mm(3) and HIV-1 RNA had been <50 copies/mL for a median (IQR) of 106.9 (43.4-227.9) weeks before enrolment. At week 48 no treatment failure had occurred in 45/50 (90%) DRV600 patients and in 47/50 (94%) DRV800 patients (difference -4%; 95% CI lower limit, -12.9%). When only patients with virological data were considered, that endpoint was met by 45/48 (94%) in the DRV600 arm and 47/49 (96%) in the DRV800 arm (difference -2.2%; 95% CI lower limit, -9.6%). Darunavir exposure was similar in the two arms. The average reduction in annual cost per successfully treated DRV600-arm patient was US$7273.The efficacy of a darunavir daily dose of 600 mg seemed to be similar to the efficacy of the standard 800 mg dose in virologically suppressed HIV-infected patients on triple ART. This strategy can potentially translate to substantial savings in the cost of care of HIV-infected patients.

TITLE: Efficacy and Safety of Varenicline for Adolescent Smoking Cessation: A Randomized Clinical Trial.ABSTRACT: Cigarette smoking is the leading cause of preventable morbidity and mortality in the United States and worldwide, and most tobacco users begin smoking in adolescence. Although advances have yielded efficacious pharmacotherapies to complement smoking cessation counseling in adults, far less progress has been made in addressing tobacco use in adolescence.To evaluate the efficacy and safety of varenicline tartrate for smoking cessation in adolescents and young adults.This 2-group randomized, placebo-controlled, double-blind intention-to-treat clinical trial enrolled a volunteer sample of treatment-seeking adolescent and young adult cigarette smokers (n = 157) aged 14 to 21 years at an outpatient clinical site in Charleston, South Carolina, from August 15, 2012, to October 20, 2017. Follow-up was completed on January 25, 2018. Data were analyzed from March 19, 2018, to August 11, 2018, with further revisions completed April 10, 2019.Participants were randomized in a 1:1 ratio to a 12-week course of varenicline (n = 77) or placebo (n = 80). All participants received weekly smoking cessation counseling.The preselected primary efficacy outcome was urine cotinine level-confirmed 7-day abstinence at the end of treatment. Secondary efficacy outcomes included weekly abstinence throughout active treatment, abstinence at posttreatment follow-up visits, and time to first 7-day abstinence. The primary safety outcome was the frequency of treatment-emergent adverse events.A total of 157 participants were enrolled (94 male [59.9%]; mean [SD] age, 19.1 [1.5] years). The varenicline and placebo groups did not differ in the primary outcome of cotinine-confirmed self-reported 7-day abstinence at the end of treatment (varenicline group, 4 of 45 [8.9%]; placebo group, 4 of 45 [8.9%]; risk ratio [RR], 0.97; 95% CI, 0.29-2.99; P = .96). However, among secondary outcomes, the varenicline group achieved self-reported earlier abstinence of at least 7 days (hazard ratio, 1.91; 95% CI, 1.12-3.27) and demonstrated higher rates of self-reported weekly abstinence during the full course of treatment (RR, 1.81; 95% CI, 1.09-2.99; P = .02) and at posttreatment follow-up (RR, 1.82; 95% CI, 1.01-3.28; P = .02). Study medication was generally well tolerated, and treatment-emergent adverse events did not differ between groups (any adverse events, 55 [71.4%] in the varenicline group vs 60 [75.0%] in the placebo group; RR, 0.95; 95% CI, 0.79-1.15; P = .61).When added to weekly cessation counseling for adolescent cigarette smokers, varenicline, compared with placebo, was well tolerated but did not improve end-of-treatment abstinence. However, varenicline may hasten abstinence and yield improvements in posttreatment abstinence outcomes.ClinicalTrials.gov identifier: NCT01509547.

TITLE: Subgroup analysis of Japanese patients in a Phase 3 study of atezolizumab in advanced triple-negative breast cancer (IMpassion130).ABSTRACT: In the randomised Phase 3 IMpassion130 trial, atezolizumab combined with nab-paclitaxel (atezo + nab-P) in 902 patients with triple-negative breast cancer (TNBC) showed prolonged progression-free survival (PFS) in both the intention-to-treat (ITT) population and programmed death-ligand 1 (PD-L1)-positive subgroup compared with placebo plus nab-P (plac + nab-P). This study assessed the efficacy and safety of atezo + nab-P in the IMpassion130 Japanese subpopulation.Eligible patients had unresectable locally advanced or metastatic TNBC previously untreated with chemotherapy for metastatic disease. Patients were randomised 1:1 to receive either atezo + nab-P or plac + nab-P. Co-primary endpoints were investigator-assessed PFS and overall survival (ITT population and PD-L1-positive subgroup). These were also assessed in the Japanese subpopulation.There were 65 Japanese patients (34 atezo + nab-P; 31 plac + nab-P). The PD-L1-positive subgroup included 25 patients (12 atezo + nab-P; 13 plac + nab-P). Median PFS was 7.4 months (atezo + nab-P) versus 4.6 months (plac + nab-P; hazard ratio [HR], 0.47; 95% CI, 0.25-0.90). In the PD-L1-positive subgroup, median PFS was 10.8 months (atezo + nab-P) versus 3.8 months (plac + nab-P; HR, 0.04; 95% CI, <0.01-0.35). Safety results in the Japanese subgroup were consistent with those in the overall population. The Japanese subgroup had a lower incidence of adverse events leading to treatment withdrawal than the overall population. More patients in the atezo + nab-P arm had neutrophil count decreases and stomatitis than patients in the plac + nab-P arm.Atezo + nab-P efficacy in Japanese patients was consistent with the overall IMpassion130 population. No new safety signals were observed, and tolerability was consistent with that of the overall population.

TITLE: Multicentre, controlled, randomised and blinded field study comparing efficacy of suxibuzone and phenylbutazone in lame horses.ABSTRACT: In horses, it has been demonstrated that suxibuzone (SBZ) has a lower gastric ulcerogenic effect than phenylbutazone (PBZ). However, no field trials have been reported comparing the efficacy of the drugs in alleviating lameness.To compare the therapeutic effect of SBZ to that of PBZ when administered orally in lame horses. Acceptability of both products was also compared.Lame horses (n = 155) were used in a multicentre, controlled, randomised and double-blinded clinical trial. Horses were treated orally with either SBZ or PBZ at equivalent therapeutic dosages. PBZ was given to 79 horses at a dose of 4.4 mg/kg bwt/12 h for 2 days, followed by 2.2 mg/kg bwt/12 h for 6 days. SBZ was given to 76 horses at 6.6 mg/kg bwt/12 h for 2 days, followed by 3.3 mg/kg bwt/ 12 h for 6 days. Efficacy of treatments was evaluated by clinicians in equine practices according to lameness progression throughout the study. Product ingestion was checked daily to evaluate product acceptability.Although SBZ showed a statistically significant tendency to have a better efficacy than PBZ (Odds ratio = 2.7; P = 0.016), significance dissipated once the analysis was adjusted for some imbalanced baseline covariates, confirming that they were actually related to the apparent advantage of SBZ over PBZ. Product acceptability was significantly higher in the SBZ group than in the PBZ group (96.1% vs. 77.2%; P = 0.001).SBZ and PBZ did not show significant differences in alleviating lameness in horses. However, SBZ had better product acceptability when administered orally with some food.SBZ is a good therapeutic alternative to PBZ in horses since there is no significant difference in alleviating lameness between the 2 therapies.

TITLE: Effective removal of leptin via hemodiafiltration with on-line endogenous reinfusion therapy.ABSTRACT: Leptin is a middle-molecular weight uremic toxin. Hemodiafiltration with on-line endogenous reinfusion (HFR) is a novel dialytic method combining the processes of diffusion, convection and adsorption. We performed a prospective crossover study of patients with end-stage renal disease to investigate the effect of HFR therapy on the level of leptin as compared to conventional low flux hemodialysis (LHD).Eleven stable hemodialysis patients were treated with LHD for 12 weeks and then treated with HFR (SG30 Plus; Sorin Group Italia S.r.1, Mirandola, Italy) for 12 weeks.After 12 weeks of HFR treatment, serum leptin levels significantly decreased (17.1 (2.66 - 39.5) at Week 12 vs. 12.3 (1.80 - 24.3) ng/ml at Week 24, p = 0.014). Although serum adiponectin levels also decreased (1.66 (1.44 - 1.86) at Week 12 vs. 1.12 (0.79 - 1.34) g/ml at Week 24, p = 0.001), the ratio of leptin to adiponectin did not increase after HFR treatment. Serum beta2-microglobulin (beta2M) levels significantly decreased (37.7 (29.8 - 42.6) at Week 12 vs. 28.3 (26.5 - 32.2) mg/dl at Week 24, p = 0.002). Dry weight, Kt/V(urea), normalized protein equivalent of nitrogen appearance, subjective global assessment, and serum albumin levels of the patients were not changed after HFR treatment. There was no difference in the serum levels of C-reactive protein or interleukin-6 between Week 12 and Week 24.The results of our study indicate that HFR may be a better therapy than LHD for removal of middle-molecular-weight uremic toxins such as leptin and b2M.

TITLE: Prostate-Only Versus Whole-Pelvic Radiation Therapy in High-Risk and Very High-Risk Prostate Cancer (POP-RT): Outcomes From Phase III Randomized Controlled Trial.ABSTRACT: We report the clinical outcomes of a randomized trial comparing prophylactic whole-pelvic nodal radiotherapy to prostate-only radiotherapy (PORT) in high-risk prostate cancer.This phase III, single center, randomized controlled trial enrolled eligible patients undergoing radical radiotherapy for node-negative prostate adenocarcinoma, with estimated nodal risk ≥ 20%. Randomization was 1:1 to PORT (68 Gy/25# to prostate) or whole-pelvic radiotherapy (WPRT, 68 Gy/25# to prostate, 50 Gy/25# to pelvic nodes, including common iliac) using computerized stratified block randomization, stratified by Gleason score, type of androgen deprivation, prostate-specific antigen at diagnosis, and prior transurethral resection of the prostate. All patients received image-guided, intensity-modulated radiotherapy and minimum 2 years of androgen deprivation therapy. The primary end point was 5-year biochemical failure-free survival (BFFS), and secondary end points were disease-free survival (DFS) and overall survival (OS).From November 2011 to August 2017, a total of 224 patients were randomly assigned (PORT = 114, WPRT = 110). At a median follow-up of 68 months, 36 biochemical failures (PORT = 25, WPRT = 7) and 24 deaths (PORT = 13, WPRT = 11) were recorded. Five-year BFFS was 95.0% (95% CI, 88.4 to 97.9) with WPRT versus 81.2% (95% CI, 71.6 to 87.8) with PORT, with an unadjusted hazard ratio (HR) of 0.23 (95% CI, 0.10 to 0.52; < .0001). WPRT also showed higher 5-year DFS (89.5% 77.2%; HR, 0.40; 95% CI, 0.22 to 0.73; = .002), but 5-year OS did not appear to differ (92.5% 90.8%; HR, 0.92; 95% CI, 0.41 to 2.05; = .83). Distant metastasis-free survival was also higher with WPRT (95.9% 89.2%; HR, 0.35; 95% CI, 0.15 to 0.82; = .01). Benefit in BFFS and DFS was maintained across prognostic subgroups.Prophylactic pelvic irradiation for high-risk, locally advanced prostate cancer improved BFFS and DFS as compared with PORT, but OS did not appear to differ.

TITLE: Effects of oral clotrimazole troches on the pharmacokinetics of oral and intravenous midazolam.ABSTRACT: The aim of the study was to determine the effects of oral clotrimazole troches on the pharmacokinetics of oral and intravenous midazolam in the plasma.We conducted a randomized, open-label, four-way crossover study in 10 healthy volunteers. Each volunteer received oral midazolam 2 mg or intravenous midazolam 0.025 mg kg(-1) with and without oral clotrimazole troches 10 mg taken three times daily for 5 days. Each study period was separated by 14 days. Serial blood samples were collected up to 24 h after oral midazolam and 6 h after intravenous midazolam. Plasma concentrations for midazolam and its metabolite 1-hydroxymidazolam were measured and fitted to a noncompartmental model to estimate the pharmacokinetic parameters.Ten healthy volunteers aged 21-26 years provided written informed consent and were enrolled into the study. Clotrimazole decreased the apparent oral clearance of midazolam from 57 +/- 13 l h(-1)[95% confidence interval 48, 66] to 36 +/- 9.8 l h(-1) (95% confidence interval 29, 43) (P= 0.003). These changes were accompanied by a decrease in the area under the concentration-time curve (mean difference 22 microg h(-1) l(-1), P= 0.001) and bioavailability (mean difference 0.21, P= NS). There were no significant differences in the systemic clearance of midazolam with or without clotrimazole troches.Oral clotrimazole troches decreased the apparent oral clearance of midazolam; no significant differences in the systemic clearance of midazolam were found.

TITLE: Predictors of embolization during protected renal artery angioplasty and stenting: Role of antiplatelet therapy.ABSTRACT: The objective of this study was to identify the predictors of distal embolization (DE) during protected renal artery angioplasty and stenting.DE may contribute to worsening renal function after renal artery stenting. The factors associated with DE, rates of platelet-rich emboli, and treatments that may prevent DE during renal stenting have not been evaluated.The current study evaluated patients randomized to receive an embolic protection device (EPD) in the RESIST trial. Forty-two patients were identified for inclusion in this study. These patients were further randomized to abciximab (N = 22) or placebo (N = 20). Modification in Diet in Renal Disease glomerular filtration rate (GFR) was used as the primary measure of renal function. Creatinine was measured by a modified Jaffe reaction using the IDMS-traceable assay. The primary endpoint was capture of platelet rich emboli in the angioguard basket.DE occurred in 15/42 (35%) of the patients and platelet rich DE in 10 (24%) of the patients who received an EPD. Of the angiographic characteristics only lesion length was significantly higher in patients with DE (16 +/- 7 mm vs. 10 +/- 5 mm, P = 0.04). Preprocedural abciximab reduced DE from 42 to 8% (P = 0.02). The rate of platelet rich emboli was 50% with neither abciximab nor a thienopyridine, 36% with thienopyridine only, 15% abciximab only, and 0% in patients who received both a thienopyridine and abciximab. Only Abciximab use was associated with improved renal function at 1-month, thienopyridine was not. Angiographic characteristics including percent stenosis, minimal luminal diameter (MLD), reference diameter, change in MLD, contrast volume, and procedure time were not predictors of DE during renal stenting.Capture of DE and specifically platelet DE are common during protected renal stenting using a filter-type EPD. Abciximab use, and potentially combined thienopyridine and abciximab use, decreased the rate of platelet rich DE; however, only abciximab improved renal function at 1-month.

TITLE: Estradiol valerate plus dienogest versus ethinylestradiol plus levonorgestrel for the treatment of primary dysmenorrhea.ABSTRACT: To demonstrate the superiority of estradiol valerate plus dienogest (E(2)V/DNG) over ethinylestradiol plus levonorgestrel (EE/LNG) in reducing the number of days with dysmenorrheic pain among women with primary dysmenorrhea.In a phase IIIb trial conducted at 44 centers worldwide between April 2009 and November 2010, otherwise healthy women aged 14-50 years requesting contraception were randomized to daily oral administration of E(2)V/DNG (n = 253) or EE/LNG (n = 254) for three 28-daycycles. The primary efficacy variable was number of days with dysmenorrheic pain, the category of which (none, mild, moderate, severe) was self-assessed on a daily basis (irrespective of menstrual bleeding status) and recorded on diary cards. Notably, the women documented their pain as they experienced it before taking any (permitted) rescue medication.Overall, 217 and 209 women receiving E(2)V/DNG and EE/LNG, respectively, completed the study. The mean ± SD change from baseline in number of days with dysmenorrheic pain was -4.6 ± 4.6 days and -4.2 ± 4.2 days for the E(2)V/DNG and EE/LNG groups, respectively (P = 0.34).Both E(2)V/DNG and EE/LNG led to considerable relief of dysmenorrheic complaints among women with primary dysmenorrhea, decreasing the number of days with dysmenorrheic pain from baseline to a similar extent.

TITLE: Effect of repaglinide on endothelial dysfunction during a glucose tolerance test in subjects with impaired glucose tolerance.ABSTRACT: Impaired glucose tolerance (IGT) is associated with increased cardiovascular risk. The pathophysiological mechanisms linking post-challenge hyperglycemia to accelerated atherosclerosis, however remain to be elucidated.A prospective, open, randomised, cross-over study was performed to investigate the effect of 2 mg repaglinide on hyperglycemia and endothelial function during an oral glucose tolerance test (75 g glucose) in 12 subjects with diagnosed IGT. Blood samples for determination of plasma glucose were drawn fasting, 1 and 2 hours after glucose ingestion. Endothelial function was assessed by measuring flow-mediated dilatation (FMD) of the brachial artery with high-resolution ultrasound.Administration of repaglinide resulted in a significant reduction of plasma glucose at 2 hours (172.8+/-48.4 vs. 138.3+/-41.2 mg/dl; p < 0.001). The flow-mediated dilatation (FMD) 2 hours after the glucose-load was significantly reduced in comparison to fasting in the control group (6.21+/-2.69 vs. 7.98+/-2.24 %; p = 0.028), whereas after theadministration of repaglinide the FMD was not significantly different to fasting values (7.24+/-2.57 vs. 8.18+/-2.93 %; p = n.s.). Linear and logistic regression analysis revealed that only the change of glucose was significantly correlated to the change of FMD observed (p < 0.001). Regression analysis after grouping for treatment and time confirmed the strong negative association of the changes of plasma glucose and FMD and indicate that the effect of repaglinide observed is based on the reduction glycemia.In subjects with IGT, the endothelial dysfunction observed after a glucose challenge is related to the extent of hyperglycemia. Reduction of hyperglycemia by repaglinide reduces endothelial dysfunction in a glucose dependent manner.

TITLE: Prevention of atrial fibrillation by bucindolol is dependent on the beta₁389 Arg/Gly adrenergic receptor polymorphism.ABSTRACT: This study assessed the impact of bucindolol, a beta-blocker/sympatholytic agent, on the development of atrial fibrillation (AF) in advanced chronic heart failure with reduced left ventricular ejection fraction (HFREF) patients enrolled in the BEST (Beta-Blocker Evaluation of Survival Trial).β-blockers have modest efficacy for AF prevention in HFREF patients. Bucindolol's effects on HF and ventricular arrhythmic endpoints are genetically modulated by β₁- and α(2c)-adrenergic receptor (AR) polymorphisms that can be used to subdivide HFREF populations into those with bucindolol effectiveness levels that are enhanced, unchanged, or lost.BEST enrolled 2,708 New York Heart Association (NYHA) class III to IV HFREF patients. A substudy in which 1,040 patients' DNA was genotyped for the β₁-AR position 389 Arg/Gly and the α(2c)322-325 wild type (Wt)/deletion (Del) polymorphisms, and new-onset AF was assessed from adverse event case report forms or electrocardiograms at baseline and at 3 and 12 months.In the entire cohort, bucindolol reduced the rate of new-onset AF compared to placebo by 41% (hazard ratio [HR]: 0.59 [95% confidence interval (CI): 0.44 to 0.79], p = 0.0004). In the 493 β₁389 arginine homozygotes (Arg/Arg) in the DNA substudy, bucindolol reduced new-onset AF by 74% (HR: 0.26 [95% CI: 0.12 to 0.57]), with no effect in β₁389 Gly carriers (HR: 1.01 [95% CI: 0.56 to 1.84], interaction test = 0.008). When β₁389 Gly carriers were subdivided by α(2c) Wt homozygotes (n = 413, HR: 0.94 [95% CI: 0.48 to 1.82], p = 0.84) or Del variant carriers (n = 134, HR: 1.33 [95% CI: 0.32 to 5.64], p = 0.70), there was a positive interaction test (p = 0.016) when analyzed with β₁389 Arg homozygotes.Bucindolol prevented new-onset AF; β₁ and α(2c) polymorphisms predicted therapeutic response; and the 47% of patients who were β₁389 Arg homozygotes had an enhanced effect size of 74%.

TITLE: Anthocyanin Intake and Physical Activity: Associations with the Lipid Profile of a US Working Population.ABSTRACT: While growing evidence exists on the independent associations between anthocyanins and physical activity on cardiovascular disease (CVD) risk determinants, the possible interaction between these exposures has not yet been studied. We aimed to study the potential synergism between anthocyanin intake and physical activity on lipid profile measures. This cross-sectional study was conducted among 249 US career firefighters participating in the trial. Anthocyanin intake was calculated using a validated food frequency questionnaire (FFQ) and physical activity level by a validated questionnaire. Multivariable linear regression models determined the extent to which anthocyanin intake and physical activity predicted lipid parameters. Generalized linear models were used for joint effect and interaction analyses on the multiplicative and additive scales. Both anthocyanins and physical activity were independently inversely associated with total cholesterol:high density lipoprotein (HDL) cholesterol. Only physical activity was inversely associated with triglycerides, low density lipoprotein (LDL) cholesterol:HDL, and triglycerides (TG):HDL. Although the combined exposure of low anthocyanin intake and low physical activity was associated with lower (RR = 2.83; 95% CI: 1.42 to 5.67) HDL cholesterol <40 mg/dL, neither multiplicative ( = 0.72) nor additive interactions were detected (relative excess risk due to interaction (RERI): 0.02; 95% CI: -1.63 to 1.66; = 0.98). Our findings provide insight on the potential synergism between anthocyanin intake and physical activity on the lipid profile.
