Abstract Background and Aims Colchicine is an anti-inflammatory drug that may prevent post-operative atrial fibrillation (POAF). The effect of this drug has been inconsistently shown in previous clinical trials. We aimed to compare the efficacy and safety of colchicine vs. placebo to prevent POAF in patients undergoing cardiac surgery. Methods and results A systematic search of EMBASE, MEDLINE, SCOPUS, ClinicalTrials.gov, and the Cochrane Library for randomized controlled trials (RCTs) was conducted from inception till April 2023. The primary outcome was the incidence of POAF after any cardiac surgery. The secondary outcome was the rate of drug discontinuation due to adverse events and adverse gastrointestinal events. Risk ratios (RR) were reported using the Mantel Haenszel method. A total of eight RCTs comprising 1885 patients were included. There was a statistically significant lower risk of developing POAF with colchicine vs. placebo (RR: 0.70; 95% CI: 0.59–0.82; P < 0.01, I2 = 0%), and this effect persisted across different subgroups. There was a significantly higher risk of adverse gastrointestinal events (RR: 2.20; 95% CI: 1.38–3.51; P < 0.01, I2 = 55%) with no difference in the risk of drug discontinuation in patients receiving colchicine vs. placebo (RR: 1.33; 95% CI: 0.93–1.89; P = 0.11, I2 = 0%). Conclusion This meta-analysis of eight RCTs shows that colchicine is effective at preventing POAF, with a significantly higher risk of adverse gastrointestinal events but no difference in the rate of drug discontinuation. Future studies are required to define the optimal duration and dose of colchicine for the prevention of POAF.

AbstractIntroductionMost patients undergoing a left atrial appendage occlusion (LAAO) procedure are admitted for overnight observation. A same‐day discharge strategy offers the opportunity to improve resource utilization without compromising patient safety. We compared the patient safety outcomes and post‐discharge complications between same‐day discharge versus hospital admission (HA) (>1 day) in patients undergoing LAAO procedure.MethodsA systematic search of MEDLINE and Embase was conducted. Outcomes of interest included peri‐procedural complications, re‐admissions, discharge complications including major bleeding and vascular complications, ischemic stroke, all‐cause mortality, and peri‐device leak >5 mm. Mantel–Haenszel risk ratios (RRs) with 95% CIs were calculated.ResultsA total of seven observational studies met the inclusion criteria. There was no statistically significant difference between same‐day discharge versus HA regarding readmission (RR: 0.61; 95% confidence interval [CI]: [0.29–1.31]; p = .21), ischemic stroke after discharge (RR: 1.16; 95% CI: [0.49–2.73]), peri‐device leak >5 mm (RR: 1.27; 95% CI: [0.42–3.85], and all‐cause mortality (RR: 0.60; 95% CI: [0.36–1.02]). The same‐day discharge study group had significantly lower major bleeding or vascular complications (RR: 0.71; 95% CI: [0.54–0.94]).ConclusionsThis meta‐analysis of seven observational studies showed no significant difference in patient safety outcomes and post‐discharge complications between same‐day discharge versus HA. These findings provide a solid basis to perform a randomized control trial to eliminate any potential confounders.

INTRODUCTION: To describe the clinical, endoscopic, and histopathology features of esophageal graft-vs-host disease (GVHD). Methods: Patients with biopsy-proven esophageal GVHD diagnosed at Mayo Clinic between 2000 and 2021 were included. Results: In 43 esophageal patients, other organ GVHD was present in 58% before and 86% at esophageal GVHD diagnosis. Esophageal specific symptoms were uncommon (dysphagia 26% and odynophagia/heartburn 5%). Esophagogastroduodenoscopy was abnormal in 72% patients demonstrating erosive esophagitis, ulceration, desquamation, or rings/furrows in a diffuse or focal pattern. DISCUSSION: There should be a low threshold for esophageal biopsies for GVHD because esophageal symptoms and endoscopic findings may be nonspecific or absent.

INTRODUCTION: We examined national Google Trends and local healthcare utilization after 3 high-impact gastroenterology publications. METHODS: Changes in US Google Trends and Olmsted County health utilization were studied. RESULTS: Publication views within 30 days were 51,458 ( Imperiale ), 49,759 ( Pimentel ), and 18,750 ( Gomm ). Colonoscopy searches ( P = 0.04) and Cologuard tests performed ( P < 0.01) increased while colonoscopies decreased ( P < 0.01). Searches for rifaximin ( P = 0.05), irritable bowel syndrome ( P < 0.01), diarrhea ( P < 0.01), and rifaximin prescriptions ( P = 0.02) increased. Increase in hydrogen-2 blocker searches ( P = 0.02) and prescriptions ( P < 0.01) and gastroesophageal reflux disease ( P < 0.01) and dementia office visits ( P < 0.01) occurred. DISCUSSION: High-impact gastroenterology publications influence Google searches and local population-based healthcare utilization.
