RESUMEN
BACKGROUND & AIMS: Endoscopic sphincterotomy (ES) is not mandatory before biliary stenting. The impact of ES before biliary stent placement remains uncertain. Previous studies have reported that ES can increase adverse event rates by up to 4.5 times compared to no ES. We aimed to assess the occurrence of post-ERCP adverse events following biliary stent placement with and without ES. METHODS: PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials. The primary outcome was post-ERCP pancreatitis (PEP). Subgroup analyses were performed with patients undergoing biliary drainage due to obstruction, using metal stents, and using plastic stents. Secondary outcomes included were post-procedure bleeding, perforation, stent/catheter occlusion, stent/catheter migration, and cholangitis. Heterogeneity was examined using I2 statistics, and a random-effects model was employed. Review manager 5.4 was used for statistical analyses. RESULTS: Seven RCTs with 1,022 patients were included. There was no significant difference between ES and non-ES groups (OR 0.46; 95% 0.19 to 1.09; p = 0.08; I2 = 59%) regarding PEP; however, a significant difference in bleeding rates was found between groups, favoring non-ES (OR 7.55; 95% CI 2.46 to 23.21; p = 0.0004; I2 = 0%). The analysis of the occurrence of cholangitis (OR 1.25; 95% CI 0.58 to 2.69; p = 0.56; I2 = 67%); perforation (OR 1.95; 95% CI 0.07 to 55.73; p = 0.70; I2 = 58%); stent/catheter migration (OR 1.95; 95% CI 0.07 to 55.73; p = 0.23; I2 = 6%); and stent/catheter occlusion (OR 0.90; 95% CI 0.37 to 2.19; p = 0.81; I2 = 0%) did not favor either group. CONCLUSION: Performing ES before biliary drainage does not impact the PEP rate but is associated with an increased postprocedure bleeding rate.
RESUMEN
INTRODUCTION: Knee pain is a major cause of disability worldwide, particularly among the elderly. Current treatments, including nonsteroidal anti-inflammatory drugs and analgesics, often lead to adverse effects. Krill oil is being explored as a potential alternative, however its efficacy in managing knee symptoms remains unclear. METHODS: MEDLINE, Embase, and Cochrane databases were searched until May 2024 for studies comparing krill oil and placebo in knee pain patients. Endpoints included knee pain, stiffness, physical function, and lipid profiles (HDL-C, LDL-C, triglycerides, and total cholesterol). A restricted maximum likelihood random-effects model with standardized mean differences (SMD) and 95% confidence intervals (CI) was used. A trial sequential analysis was conducted to evaluate further research implications. RESULTS: We included five trials with 700 patients using krill oil for knee pain. Results showed no significant difference between krill oil and placebo for knee pain, knee stiffness, and lipid profiles. However, krill oil demonstrated a significant small effect in improving knee physical function (SMD -0.24, 95% CI [-0.41; -0.08], I2 = 0%).Trial sequential analysis provided certainty that krill oil enhances knee physical function compared to placebo and indicated no improvement in knee pain, but the findings for knee stiffness need to be confirmed by further research. CONCLUSION: This study found that krill oil supplementation did not significantly improve knee pain, stiffness, or lipid profile, although it may help knee physical function. Based on these findings, krill oil supplementation is not yet justified for knee pain.
RESUMEN
BACKGROUND: Catheter ablation has become a widely accepted treatment for atrial fibrillation, but early recurrences remain a challenge, often attributed to inflammatory responses triggered during the procedure. This systematic review and meta-analysis aimed to evaluate the effectiveness of colchicine in preventing short-term AF recurrence post-ablation. METHOD: PubMed, Embase, and Cochrane Library were searched for studies comparing use of colchicine and placebo in patients after AF ablation. Outcomes included AF recurrence, GI side effects, and hospitalization. R program (version 4.3.2) was used for statistical analysis. Heterogeneity was assessed with I2 statistics. RESULTS: Five studies, including 1592 patients, were analyzed. Pooled results revealed no statistically significant decrease in AF recurrence (OR 0.74; 95% CI 0.48-1.12; p = 0.153) and pericarditis rates (OR 0.67; 95% CI 0.26-1.72; p = 0.403) with colchicine use. No significant difference in hospitalization rates was observed between colchicine and placebo groups (OR 1.00; 95% CI 0.63-1.59; p = 0.996). In addition, gastrointestinal side effects were notably higher in the colchicine group (OR 4.84; 95% CI 2.58-9.05; p < 0.001). CONCLUSION: Prophylactic use of colchicine after atrial ablation was not associated with a reduction in AF recurrence and pericarditis rates. In addition, there was no difference in the rate of all-cause hospitalization between the groups, and colchicine use was associated with gastrointestinal adverse events.
RESUMEN
BACKGROUND: The efficacy and safety of adjunctive statin therapy in hospitalized patients with coronavirus disease 2019 (Covid-19) remains uncertain. METHODS: We systematically searched Medline, Embase, Cochrane, and ClinicalTrials.gov databases from inception to late April 2024 for randomized controlled trials (RCTs) comparing statin versus no statin use in patients hospitalized with Covid-19. We pooled risk ratios (RRs) and hazard ratios (HRs) with 95% confidence intervals (CIs) applying a random-effects model. R version 4.3.1 was used for statistical analyses. RESULTS: We included 7 RCTs comprising 4,262 patients, of whom 2,645 (62%) were randomized to receive statin therapy. Compared with no statin, statin use significantly reduced case-fatality rate (RR 0.88; 95% CI 0.80-0.98; I2 = 0%). In a time-to-event analysis, we found similar results (HR 0.86; 95% CI 0.75-0.99; I2 = 0%). Statin use also significantly reduced World Health Organization (WHO) scale at 14 days (mean difference -0.27; 95% CI -0.54 to -0.01; I2 = 0%). There was no statistically significant difference between the two groups in length of hospital stay, elevation of liver enzymes, and C-reactive protein levels. CONCLUSIONS: In patients hospitalized with Covid-19, statins significantly reduced case-fatality rate and WHO scale score. REGISTRATION: A prospective register was recorded in International Prospective Register of Systematic Reviews (PROSPERO) with the number CRD42023479007.
RESUMEN
Ustekinumab and vedolizumab are key treatment options for Crohn's disease patients who fail anti-tumor necrosis factor (TNF) therapy. This updated meta-analysis aims to compare the efficacy and safety of these two drugs. We performed a systematic review in PubMed, Embase , and Cochrane databases searching for randomized and nonrandomized studies comparing vedolizumab versus ustekinumab in patients with Crohn's disease with previous anti-TNF failure or intolerance. The primary outcome was steroid-free clinical remission (SFR) at the pos-induction (12-16 weeks) and maintenance period (48-52 weeks). The odds ratio (OR) was used for binary outcomes with their respective 95% confidence interval (CI). Heterogeneity was assessed using the Cochran Q test and I2 statistics. This meta-analysis included 11 studies and 2724 patients. There was a significant difference favoring ustekinumab in SFR at pos-induction (OR, 1.44; 95% CI, 1.11-1.88; P â =â 0.006; I2 â =â 27%) and maintenance periods (OR, 1.86; 95% CI, 1.23-2.82; P â =â 0.003; I2 â =â 80%), in clinical remission at pos-induction period (OR, 2.04; 95% CI, 1.58-2.63; P â <â 0.001; I2 â =â 3%), and in treatment discontinuation due to adverse events (OR, 0.31; 95% CI, 0.16-0.60; P â <â 0.001; I2 â =â 0%). In patients with Crohn's disease with prior anti-TNF failure, ustekinumab showed higher SFR during both the pos-induction and maintenance period and a lower rate of treatment discontinuation due to adverse events.
