Evaluation of Quality of Diabetic Foot Examination on YouTube

Introduction: Foot ulcers and amputations are common conditions in people with diabetes and can considerably impact quality of life, necessitate a lengthy hospital stay and increase mortality. Preventative foot care and examination can prevent or delay ulceration, and individuals may seek information from publicly available social media resources such as YouTube. Therefore, the purpose of this study is to evaluate the educational quality and reliability of publicly available YouTube videos on diabetes foot examinations.  Method: A YouTube search for “diabetic foot examination” was conducted, and the first 100 relevant English videos focused on examining the diabetic foot were included for evaluation. The Journal of the American Medical Association (JAMA) standards were used to measure video reliability. The Global Quality Score (GQS) and the Diabetes UK Annual Foot Check (DUK-C) checklist were used to assess video educational quality. Differences in JAMA, GQS, and DUK-C ratings were analysed after videos were sorted by topic and source.  Results: The mean number of views per video was 101,311.9 ± 348,383.6, and the mean video power index was 41.6 ± 170.0. The most common upload source was from physicians (28%) and, the most popular material category was diabetes foot examination (58 videos). In terms of video reliability, 36% of videos scored 0. According to the GQS standards, only 5% of the videos are of excellent quality, while 34% are of poor quality, with 24 videos scoring between 0 and 1 on the DUK-C scale.  Conclusion: While foot care examination videos have a substantial audience, the majority are considered low in quality and reliability. Videos on comprehensive diabetic foot examination should be accessed on reputable sources that guarantee standardisations of video quality and take into account the simplification of information transmission in order to reach lay audiences.</p

The importance of physical activity in management of type 2 diabetes and COVID-19

Over time, various guidelines have emphasised the importance of physical activity and exercise training in the management of type 2 diabetes, chronic diseases, including cardiovascular disease and musculoskeletal disorders. The aim of this review is to evaluate the effectiveness of physical activity in people with type 2 diabetes and COVID-19. Most research to date indicates that people with type 2 diabetes who engage in both aerobic and resistance exercise see the greatest improvements in insulin sensitivity. Physical activity is now also known to be effective at reducing hospitalisation rates of respiratory viral diseases, such as COVID-19, due to the beneficial impacts of exercise on the immune system. Preliminary result indicates that home-based exercise may be an essential component in future physical activity recommendations given the current COVID-19 pandemic and the need for social distancing. This home-based physical exercise can be easily regulated and monitored using step counters and activity trackers, enabling individuals to manage health issues that benefit from physical exercise

Physical activity and risk of chronic kidney disease: systematic review and meta-analysis of 12 cohort studies involving 1,281,727 participants

The role of regular physical activity in preventing vascular and non-vascular disease is well established. Chronic kidney disease (CKD) is a major cause of global morbidity and mortality and largely preventable, but it is uncertain if regular physical activity can reduce the risk of CKD. Using a systematic review and meta-analysis of published observational cohort studies in the general population, we sought to assess the association between physical activity and CKD risk. Relevant studies with at least one-year of follow-up were sought from inception until 02 May 2022 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Relative risks (RRs) with 95% confidence intervals (CIs) for the maximum versus the minimal amount of physical activity groups were pooled using random effects meta-analysis. The quality of the evidence was evaluated using the GRADE tool. A total of 12 observational cohort studies comprising 1,281,727 participants and 66,217 CKD events were eligible for the analysis. The pooled multivariable-adjusted RR (95% CI) of CKD comparing the most versus the least physically active groups was 0.91 (0.85–0.97). The association was consistent across several study level subgroups. Exclusion of any single study at a time from the meta-analysis did not change the direction or significance of the association. There was no evidence of small study effects among contributing studies. The GRADE quality of the evidence was low. In the general population, individuals who are most physically active have a lowered risk of CKD compared to those who are not or least physically active. CRD42022327640

The effects of weight-lowering pharmacotherapies on physical activity, function and fitness: A systematic review and meta-analysis of randomized controlled trials

Weight-lowering pharmacotherapies provide an option for weight management; however, their effects on physical activity, function, and cardiorespiratory fitness are not fully understood. We conducted a systematic review and meta-analysis of randomized controlled trials to investigate the effect of licensed weight loss pharmacotherapies on physical activity, physical function, and cardiorespiratory fitness in individuals with obesity. Fourteen trials met our prespecified inclusion criteria: Five investigated liraglutide, four semaglutide, three naltrexone/bupropion, and two phentermine/topiramate. All 14 trials included a self-reported measure of physical function, with the pooled findings suggesting an improvement favoring the pharmacotherapy intervention groups (SMD: 0.27; 95% CI: 0.22 to 0.32) and effects generally consistent across different therapies. Results were also consistent when stratified by the two most commonly used measures: The Short-Form 36-Item Questionnaire (SF-36) (0.24; 0.17 to 0.32) and the Impact of Weight on Quality Of Life-Lite (IWQOL-Lite) (0.29; 0.23 to 0.35). Meta-regression confirmed a significant association between pharmacotherapy induced weight loss and improved physical function for IWQOL-Lite (p = 0.003). None of the studies reported a physical activity outcome, and only one study reported objectively measured cardiorespiratory fitness. Improvements in self-reported physical function were observed with weight loss therapy, but the effect on physical activity or objectively measured physical function and fitness could not be determined
