Carbohydrate antigen 125 and clinical outcomes in heart failure: systematic review and meta-analysis - BMC Cardiovascular Disorders
Introduction Carbohydrate Antigen 125 (CA125) has emerged as a potential biomarker in patients with heart failure (HF). This meta-analysis comprehensively evaluates the association between CA125 levels and clinical outcomes across HF populations. Methods We conducted this study based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). We systematically searched PubMed, Scopus, Web of Science, and Embase libraries up to April 2025. We selected the original English-language investigations that reported the association between CA125 levels and clinical outcomes in cases with HF. The random-effects model and Hartung-Knapp-Sidik-Jonkman method were used to pool effect sizes and report summary statistics. The current review was registered in PROSPERO (CRD420251023141). Results A total of 20,458 cases were included from 29 studies, with an average age of 70.3 years, and 36.1% of cases were women. The average cut-off level was 37.78 U/mL, and 35 U/mL was mainly used as the CA125 cut-off level. A meta-analysis of nine studies that reported the risk of experiencing endpoint events (death or HF-related hospitalization) showed significantly higher risk (HR 2.23, 95% CI 1.69–2.93; p < 0.01; I2 = 75.0%) among the patients with higher CA125 levels compared to those with lower levels. The increased risk remained significant across the acute heart failure (AHF) (HR based on two studies: 1.88, 95% CI 1.54–2.30; p < 0.01; I2 = 39.6%) and chronic heart failure (CHF) (HR based on seven studies: 2.52, 95% CI 1.69–3.77; p < 0.01; I2 = 77.4%) subgroups. Furthermore, a correlation meta-analysis of 13 studies revealed a significant direct correlation between CA125 and pro-BNP levels (r = 0.42; 95% CI 0.30 to 0.54; p < 0.01; I2 = 96.9%). Conclusion The current review findings revealed CA125 as a significant prognostic factor of mortality and hospitalization risks in HF population. Furthermore, CA125 could be a non-invasive and operator-independent tool for evaluating disease severity and monitoring response to therapy. We suggested CA125 for monitoring various treatments in individuals with HF, specifically diuretic therapy. Further prospective studies are needed to determine the optimal cut-off for CA125 levels in HF.

GLP-1 receptor agonists (GLP-1RAs) boost weight loss and help fight #WeightRegain after #BariatricSurgery, according to the latest #MetaAnalysis. Early treatment shows greater effects. Most side effects are mild and gastrointestinal. More long-term data needed! link.springer.com/article/10.1...
The role of glucagon-like peptide-1 receptor agonists in weight regain treatment or prevention after bariatric surgery: a systematic review and meta-analysis - Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity
Background Weight regain (WR) and insufficient weight loss (WL) occur in 20–25% of patients after bariatric surgery due to various factors. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown promise in promoting WL; however, evidence regarding their effectiveness in managing WL and preventing WR post-bariatric surgery remains limited. Objective This study aims to evaluate the role of GLP-1RAs in treating and preventing WR following bariatric surgery. Methods A systematic search was conducted across PubMed, Scopus, and Web of Science for studies assessing the impact of GLP-1RAs on WR after bariatric surgery. Results Our search identified 27 original studies, with 10 included in the meta-analysis involving 769 participants (392 treated with GLP-1RAs). The mean age was 44.05 years, with 30.47% male. The time interval from surgery to the initiation of GLP-1RAs treatment ranged from 1.5 to 86.7 months, with treatment durations between 4 and 12 months. The analysis showed significantly greater WL in the GLP-1RAs group compared to placebo (SMD = 0.82, 95% CI 0.23 to 1.42). Subgroup analysis for treatment durations ≤ 6 months indicated a higher WL in the GLP-1RAs group (SMD = 0.79, 95% CI 0.25 to 1.34). Adverse events were primarily gastrointestinal, with nausea significantly more frequently in the GLP-1RAs group (OR = 2.01, 95% CI 1.24 to 3.27). Conclusion GLP-1RAs effectively promote WL among participants experiencing WR after bariatric surgery. Initiating GLP-1RAs therapy shortly after surgery may help prevent WR. Further research is warranted to explore long-term outcomes and optimize treatment protocols for this patient population. Graphical Abstract
