ObjectiveTo investigate the bidirectional causal relationship between metabolic syndrome (MS) and inflammatory bowel disease (IBD) using Mendelian randomization (MR). MethodsWe extracted genetic variants with strong correlations from genome-wide association study data on MS as instrumental variables. Inverse variance weighting, MR-Egger regression methods, and weighted median methods were used to estimate the causal effect of MS and risk of developing IBD. ResultsInverse variance weighting found that genetically predicted MS was associated with an increased risk of developing IBD overall (OR=1.113, 95%CI 1.020 to 1.216, P=0.017) and Crohn's disease (OR=1.195, 95%CI 1.072 to 1.333, P=0.001). And inverse MR analysis found ulcerative colitis was associated with a reduced risk of developing MS (OR=0.969, 95%CI 0.948 to 0.991, P=0.005). ConclusionThe results based on MR analysis suggest that genetically predicted MS is associated with the risk of IBD as a whole and Crohn's disease and ulcerative colitis are associated with a reduced risk of developing MS.
Objective To evaluate and summarize the evidence related to non-pharmacological interventions in community-dwelling elderly with sarcopenia and to provide an evidence-based basis for guiding community health professionals to effectively manage older patients with sarcopenia. Methods We searched all evidence about non-pharmacological interventions in community-dwelling elderly with sarcopenia from BMJ Best Practice, UpToDate, Guidelines International Network, National Institute for Health and Care Excellence, Scottish Intercollegiate Guidelines Network, Registered Nurses' Association of Ontario, Canadian Medical Association Clinical Practice Guidelines Infobase, American Society for Nutrition, Australian JBI Evidence-Based Health Care Centre Database, CINAHL, PubMed, Cochrane Library, Web of Science, CBM, CNKI, WanFang Data and VIP Databases. The types of literature included guidelines, expert consensus, systematic reviews, evidence summaries and meta-analyses. The retrieval time ranged from January 1, 2019 to May 31, 2024. Results A total of 14 publications were included, including 2 guidelines, 3 expert consensuses, and 9 systematic reviews. Twenty-four pieces of evidence were summarized in 3 areas, including screening, assessment, and non-pharmacological interventions for sarcopenia. Conclusion We summarize the best evidence for initial screening, systematic assessment, and comprehensive non-pharmacological interventions for elderly patients with sarcopenia in the community, and provide a guidance and reference for community medical staff to efficiently manage elderly patients with sarcopenia.
