243 Background: AA and D have been shown in separate trials to increase overall survival in patients with mCSPC compared to Androgen Derivation Therapy (ADT). In the absence of head to head clinical trials and to provide clinical guidance, we performed an indirect comparison of AA and D using network meta-analysis. Methods: We performed a search of MEDLINE, EMBASE, Cochrane Library, and Cochrane Central Register of Controlled Trials to identify relevant clinical trials. Collected data included hazard ratio and confidence interval (CI) for Overall Survival (OS) and number of adverse events in each study arm. Risk for bias was assessed using the Cochrane Collaboration’s tool. Bayesian network meta-analysis was conducted using WinBUGS 1.4.3 software (MRC Biostatistics Unit, Cambridge, UK) to perform an indirect comparison of D and AA. Results: Five clinical trials were included in this analysis. Two trials (LATITUDE, STAMPEDE) compared AA to ADT and three trials (CHAARTED,STAMPEDE, GETUG-AFU 15 study) compared D to ADT. Results from both fixed effect and random effect network meta-analyses for the primary outcome (OS) revealed no statistical significance between AA and D (HR 0.81,95%CI 0.65-1.01; HR 0.81, 95%CI 0.40-1.82) respectively. Comparatively, abiraterone had statistically significant fewer events of anemia (OR 0.14,95%CI 0.08-0.23), neutropenia (OR 0.06,95%CI 0.03-0.12), peripheral edema (OR 0.21,95%CI 0.09-0.44), dyspnea (OR 0.22,95%CI 0.08-0.51), nausea (OR 0.09,95%CI 0.02-0.24), diarrhea (OR 0.06,95%CI 0.02-0.15), constipation (OR 0.25,95%CI 0.11-0.53), and fatigue (OR 0.12,95%CI 0.07-0.20). AA had statistically significant more events of hot flashes (OR 3.85, 95% CI2.33-6.25). For other adverse events, both drugs were statistically similar. Conclusions: There is no difference in OS using AA for longer periods in CSPC than a regimen of a limited number of cycles of D. There are significant differences in side effect profile of these drugs. Further analyses are needed to determine cost effectiveness of AA vs D under consideration of comparative efficacy and safety.

Purpose: To evaluate a healthy eating and physical activity intervention for immigrant families, derived through community-based participatory research. Design: The Healthy Immigrant Families study was a randomized controlled trial with delayed intervention control group, with families as the randomization unit. Setting: US Midwest city. Participants: Participants were recruited by community partners from Hispanic, Somali, and Sudanese immigrant communities. Intervention: Family health promoters from participating communities delivered 6 healthy eating modules, 4 physical activity modules, and 2 modules synthesizing information in 12 home visits (60-90 minutes) within the first 6 months. Up to 12 follow-up phone calls to each participant occurred within the second 6 months. Measures: Primary measures were dietary quality measured with weekday 24-hour recall and reported as Healthy Eating Index score (0-100) and physical activity measured with accelerometers (14 wear days) at baseline, 6, 12, and 24 months. Results: In total, 151 persons (81 adolescents and 70 adults; 44 families) were randomly assigned. At 12 months, significant improvement occurred in Healthy Eating Index scores for adults in the intervention group compared with controls (change, +8.6 vs −4.4; P < .01) and persisted at 24 months (+7.4 from baseline; P < .01). No differences were observed for adolescents and no significant differences occurred between groups for physical activity. Conclusion: This intervention produced sustained dietary quality improvement among adults but not among adolescents. Program outcomes are relevant to communities working to decrease cardiovascular risk among immigrant populations.

Abstract Aims This study was designed to evaluate the safety, tolerability and haemodynamic effects of BMS-986231, a novel second-generation nitroxyl donor with potential inotropic, lusitropic and vasodilatory effects in patients hospitalized with decompensated heart failure and reduced ejection fraction (HFrEF). Methods and results Forty-six patients hospitalized with decompensated HFrEF were enrolled into four sequential dose-escalation cohorts in this double-blind, randomized, placebo-controlled Phase 2a study. Patients with baseline pulmonary capillary wedge pressure (PCWP) of ≥20 mmHg and a cardiac index of ≤2.5 L/min/m2 received one 6-h i.v. infusion of BMS-986231 (at 3, 5, 7 or 12 µg/kg/min) or placebo. BMS-986231 produced rapid and sustained reductions in PCWP, as well as consistent reductions in time-averaged pulmonary arterial systolic pressure, pulmonary arterial diastolic pressure and right atrial pressure. BMS-986231 increased non-invasively measured time-averaged stroke volume index, cardiac index and cardiac power index values, and decreased total peripheral vascular resistance. There was no evidence of increased heart rate, drug-related arrhythmia or symptomatic hypotension with BMS-986231. Analyses of adverse events throughout the 30-day follow-up did not identify any toxicities specific to BMS-986231, with the potential exception of infrequent mild-to-moderate headaches during infusion. There were no treatment-related serious adverse events. Conclusions BMS-986231 demonstrated a favourable safety and haemodynamic profile in patients hospitalized with advanced heart failure. Based on preclinical data and these study's findings, it is possible that the haemodynamic benefits may be mediated by inotropic and/or lusitropic as well as vasodilatory effects. The therapeutic potential of BMS-986231 should be further assessed in patients with heart failure.

Purpose The purpose of this pilot feasibility project was to examine the potential effectiveness of a digital storytelling intervention designed through a community-based participatory research (CBPR) approach for immigrants and refugees with type 2 diabetes mellitus (T2DM). Methods The intervention was a 12-minute culturally and linguistically tailored video consisting of an introduction, 4 stories, and a concluding educational message. A structured interview was used to assess the intervention for acceptability, interest level, and usefulness among 25 participants with T2DM (15 Latino, 10 Somali) across 5 primary care clinical sites. After watching the video, participants rated their confidence and motivation about managing T2DM as a result of the intervention. Baseline A1C and follow-up values (up to 6 months) were abstracted from medical records. Results All participants reported that the intervention got their attention, was interesting, and was useful; 96% reported that they were more confident about managing their T2DM than before they watched the video, and 92% reported that the video motivated them to change a specific behavior related to T2DM self-management. The mean baseline A1C level for the intervention participants was 9.3% (78 mmol/mol). The change from baseline to first follow-up A1C level was −0.8% (−10 mmol/mol) ( P < .05). Conclusions Implementation of a digital storytelling intervention for T2DM among immigrant populations in primary care settings is feasible and resulted in self-rated improvement in psychosocial constructs that are associated with healthy T2DM self-management behaviors, and there was some evidence of improvement in glycemic control. A large-scale efficacy trial of the intervention is warranted.

AbstractAfter decades on the margins of primary health care, surgical and anaesthesia care is gaining increasing priority within the global development arena. The 2015 publications of the Disease Control Priorities third edition on Essential Surgery and the Lancet Commission on Global Surgery created a compelling evidenced‐based argument for the fundamental role of surgery and anaesthesia within cost‐effective health systems strengthening global strategy. The launch of the Global Alliance for Surgical, Obstetric, Trauma, and Anaesthesia Care in 2015 has further coordinated efforts to build priority for surgical care and anaesthesia. These combined efforts culminated in the approval of a World Health Assembly resolution recognizing the role of surgical care and anaesthesia as part of universal health coverage. Momentum gained from these milestones highlights the need to identify consensus goals, targets and indicators to guide policy implementation and track progress at the national level. Through an open consultative process that incorporated input from stakeholders from around the globe, a global target calling for safe surgical and anaesthesia care for 80% of the world by 2030 was proposed. In order to achieve this target, we also propose 15 consensus indicators that build on existing surgical systems metrics and expand the ability to prioritize surgical systems strengthening around the world.

The sequence of events that lead to inflammation and fibrosing nonalcoholic steatohepatitis (NASH) is incompletely understood. Hence, we investigated the chronology of whole body, tissue, and cellular events that occur during the evolution of diet-induced NASH. Male C57Bl/6 mice were assigned to a fast-food (FF; high calorie, high cholesterol, high fructose) or standard-chow (SC) diet over a period of 36 wk. Liver histology, body composition, mitochondrial respiration, metabolic rate, gene expression, and hepatic lipid content were analyzed. Insulin resistance [homeostasis model assessment-insulin resistance (HOMA-IR)] increased 10-fold after 4 wk. Fibrosing NASH was fully established by 16 wk. Total hepatic lipids increased by 4 wk and remained two- to threefold increased throughout. Hepatic triglycerides declined from sixfold increase at 8 wk to threefold increase by 36 wk. In contrast, hepatic cholesterol levels steadily increased from baseline at 8 wk to twofold by 36 wk. The hepatic immune cell population altered over time with macrophages persisting beyond 16 wk. Mitochondrial oxygen flux rates of FF mice diet were uniformly lower with all the tested substrates (13–276 pmol·s−1·ml−1 per unit citrate synthase) than SC mice (17–394 pmol·s−1·ml−1 per unit citrate synthase) and was accompanied by decreased mitochondrial:nuclear gene copy number ratios after 4 wk. Metabolic rate was lower in FF mice. Mitochondrial glutathione was significantly decreased at 24 wk in FF mice. Expression of dismutases and catalase was also decreased in FF mice. The evolution of NASH in the FF diet-induced model is multiphasic, particularly in terms of hepatic lipid composition. Insulin resistance precedes hepatic inflammation and fibrosis. Mitochondrial dysfunction and depletion occur after the histological features of NASH are apparent. Collectively, these observations provide a unique overview of the sequence of changes that coevolve with the histological evolution of NASH. NEW & NOTEWORTHY This study demonstrates in a first of kind longitudinal analysis, the evolution of nonalcoholic steatohepatitis (NASH) on a fast-food diet-induced model. Key findings include 1) hepatic lipid composition changes in a multiphasic fashion as NASH evolves; 2) insulin resistance precedes hepatic inflammation and fibrosis, answering a longstanding chicken-and-egg question regarding the relationship of insulin resistance to liver histology in NASH; and 3) mitochondrial dysfunction and depletion occur after the histological features of NASH are apparent.

Abstract Objective Behçet's disease ( BD ) is a chronic, relapsing, inflammatory vascular disease with no pathognomonic test. Low sensitivity of the currently applied International Study Group ( ISG ) clinical diagnostic criteria led to their reassessment. Methods An International Team for the Revision of the International Criteria for BD (from 27 countries) submitted data from 2556 clinically diagnosed BD patients and 1163 controls with BD ‐mimicking diseases or presenting at least one major BD sign. These were randomly divided into training and validation sets. Logistic regression, ‘leave‐one‐country‐out’ cross‐validation and clinical judgement were employed to develop new International Criteria for BD ( ICBD ) with the training data. Existing and new criteria were tested for their performance in the validation set. Results For the ICBD , ocular lesions, oral aphthosis and genital aphthosis are each assigned 2 points, while skin lesions, central nervous system involvement and vascular manifestations 1 point each. The pathergy test, when used, was assigned 1 point. A patient scoring ≥4 points is classified as having BD . In the training set, 93.9% sensitivity and 92.1% specificity were assessed compared with 81.2% sensitivity and 95.9% specificity for the ISG criteria. In the validation set, ICBD demonstrated an unbiased estimate of sensitivity of 94.8% (95% CI : 93.4–95.9%), considerably higher than that of the ISG criteria (85.0%). Specificity (90.5%, 95% CI : 87.9–92.8%) was lower than that of the ISG ‐criteria (96.0%), yet still reasonably high. For countries with at least 90%‐of‐cases and controls having a pathergy test, adding 1 point for pathergy test increased the estimate of sensitivity from 95.5% to 98.5%, while barely reducing specificity from 92.1% to 91.6%. Conclusion The new proposed criteria derived from multinational data exhibits much improved sensitivity over the ISG criteria while maintaining reasonable specificity. It is proposed that the ICBD criteria to be adopted both as a guide for diagnosis and classification of BD .
