To identify what features of online social networks can increase physical activity, we conducted a 4-arm randomized controlled trial in 2014 in Philadelphia, PA. Students (n = 790, mean age = 25.2) at an university were randomly assigned to one of four conditions composed of either supportive or competitive relationships and either with individual or team incentives for attending exercise classes. The social comparison condition placed participants into 6-person competitive networks with individual incentives. The social support condition placed participants into 6-person teams with team incentives. The combined condition with both supportive and competitive relationships placed participants into 6-person teams, where participants could compare their team’s performance to 5 other teams' performances. The control condition only allowed participants to attend classes with individual incentives. Rewards were based on the total number of classes attended by an individual, or the average number of classes attended by the members of a team. The outcome was the number of classes that participants attended. Data were analyzed using multilevel models in 2014. The mean attendance numbers per week were 35.7, 38.5, 20.3, and 16.8 in the social comparison, the combined, the control, and the social support conditions. Attendance numbers were 90% higher in the social comparison and the combined conditions (mean = 1.9, SE = 0.2) in contrast to the two conditions without comparison (mean = 1.0, SE = 0.2) (p = 0.003). Social comparison was more effective for increasing physical activity than social support and its effects did not depend on individual or team incentives.
Previous meta-analyses comparing the efficacy of psychotherapeutic interventions for depression were clouded by a limited number of within-study treatment comparisons. This study used network meta-analysis, a novel methodological approach that integrates direct and indirect evidence from randomised controlled studies, to re-examine the comparative efficacy of seven psychotherapeutic interventions for adult depression.

As reports on possible associations between microbes and the host increase in number, more meaningful interpretations of this information require an ability to compare data sets across studies. This is dependent upon standardization of workflows to ensure comparability both within and between studies. Here we propose the standard use of an alternate collection and stabilization method that would facilitate such comparisons. The DNA Genotek OMNIgene∙Gut Stool Microbiome Kit was compared to the currently accepted community standard of freezing to store human stool samples prior to whole genome sequencing (WGS) for microbiome studies. This stabilization and collection device allows for ambient temperature storage, automation, and ease of shipping/transfer of samples. The device permitted the same data reproducibility as with frozen samples, and yielded higher recovery of nucleic acids. Collection and stabilization of stool microbiome samples with the DNA Genotek collection device, combined with our extraction and WGS, provides a robust, reproducible workflow that enables standardized global collection, storage, and analysis of stool for microbiome studies.
PURPOSE: To compare nylon monofilament suture with polytetrafluoroethylene sheet for frontalis suspension surgery to treat eyes with congenital ptosis. DESIGN: Retrospective, nonrandomized, comparative, interventional case series. METHODS: We reviewed the medical records of 49 patients who had undergone 79 eyelid frontalis suspension surgeries to treat congenital ptosis. All of the patients were younger than 16 years and had congenital ptosis with poor levator muscle function. They were treated with frontalis suspension surgery with either a nylon suture or a polytetrafluoroethylene sheet and were followed up for at least 1 year. A single rhomboid loop sling was used for the nylon suture surgery. For the polytetrafluoroethylene sheet, an incision was made in the eyelid crease, and one end of the sheet was fixed to the tarsus and the other was fixed to the frontalis muscle. The main outcome measures were postoperative recurrences and complications. RESULTS: We evaluated 37 eyelids of 25 patients after nylon suture surgery and 42 eyelids of 31 patients after polytetrafluoroethylene sheet surgery. Among these, 9 eyelids of 7 patients were included in both groups. The median postoperative follow-up period was 32 months in both groups. The recurrence rates were 62.2% for the nylon suture group and 0% for the polytetrafluoroethylene sheet group (P < .001). The postoperative complication rates were 0% for the nylon suture group and 7.1% for the polytetrafluoroethylene sheet group (P > .05). CONCLUSIONS: Frontalis suspension using a polytetrafluoroethylene sheet with direct tarsus and frontalis muscle fixation is a reasonable technique with low rates of recurrences and complications.

The aim of this study was to compare the effects of 5-week high-intensity interval training (HIIT) and moderate-to-vigorous intensity continuous training (MVCT) on cardiometabolic health outcomes and enjoyment of exercise in obese young women.
Bold claims have been made for the ability of the WHO surgical checklist to reduce surgical morbidity and mortality and improve patient safety regardless of the setting. Little is known about how far the challenges faced by low-income countries are the same as those in high-income countries or different. We aimed to identify and compare the influences on checklist implementation and compliance in the UK and Africa.
