Background Effective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach enhance prediction efficacy over multiple time intervals. Methods We utilized...

Abstract Objectives The US Preventive Services Task Force lowered the recommended starting age for colorectal cancer (CRC) screening in average‐risk adults from 50 to 45 years. We aimed estimate global burden and trends of aged 20–49 years (early‐onset CRC). Methods This is an analysis Global Burden Diseases, Injuries, Risk Factors Study 2019 (GBD 2019). GBD estimation methods were used describe incidence, mortality, disability‐adjusted life (DALYs) early CRC 1990 2019. Data 204 countries...

Background: Currently, no large, nationwide studies have been conducted to analyze the demographic factors, underlying comorbidities, clinical outcomes, and health care utilization in rhabdomyolysis patients with without acute kidney injury (AKI). Methods: We queried National Inpatient Sample of Healthcare Cost Utilization Project (HCUP) from 2016 2018. The chi-squared test was used compare categorical variables, adjusted Wald employed quantitative variables. logistic regression model...

Abstract Cholecystectomy is the standard treatment for acute cholecystitis, but it may not be suitable all patients. For those who cannot undergo surgery, a percutaneous cholecystostomy tube (PCT) and ERCP-guided transpapillary gallbladder drainage are viable options. We aimed to perform nationwide study assess 30-day readmission rates, adverse events (AEs), mortality rates in these two cohorts. conducted cohort using data from Nationwide Readmissions Database (NRD) 2016 2019. identified...

Prior international studies have shown mixed results regarding the association of hepatitis B and C with adverse pregnancy outcomes. We performed an updated evaluation prevalence associated outcomes evaluated trends over time diagnosis chronic (HBV) (HCV) in pregnant women a national database. All HBV HCV were identified from National Inpatient Sample database 2012 to 2018. Multivariate logistic regression analyses compare pregnancy-related complications, including rates...

Abstract Background An increasing incidence of pediatric-onset inflammatory bowel disease (PIBD) has been reported in many countries. However, the global burden and distribution this remain less understood. We aimed to examine epidemiology trends PIBD from 1990 2019. Methods Data 2019 Global Burden Disease Study, covering 204 countries, were analyzed. assessed key measures like incidence, prevalence, mortality, disability-adjusted life years (DALYs) using linear regression calculate annual...

Background Alzheimer disease and related dementias (ADRD) rank as the sixth leading cause of death in United States, underlining importance accurate ADRD risk prediction. While recent advancements prediction have primarily relied on imaging analysis, not all patients undergo medical before an diagnosis. Merging machine learning with claims data can reveal additional factors uncover interconnections among diverse codes. Objective The study aims to use graph neural networks (GNNs) claim for...

INTRODUCTION: Liver disease is a significant public health problem in the United States, with notable racial disparities mortality. This study examines liver mortality trends among Black and White populations during 1999–2020. METHODS: We used CDC WONDER database to ascertain age-standardized rates Americans. Annual percent change was calculated. Age-standardized absolute rate difference ratios were computed by subtracting dividing population's from that of population. RESULTS: diseases...

Background: There is increasing evidence that cold endoscopic mucosal resection (c-EMR) can effectively treat large colorectal polyps. We aim to appraise the current literature and evaluate outcomes following c-EMR for nonpedunculated colonic polyps ≥20 mm. Methods: Major databases were searched. Primary included recurrence rate adverse events. Meta-analysis was performed using a random-effects model. Results: Nine articles in final analysis, which 817 patients 1077 Average polyp size 28.8...
