Therapeutic trials with high-dose lansoprazole and omeprazole have been shown to be sensitive clinical tools for diagnosing patients gastro-oesophageal reflux disease-related non-cardiac chest pain.To determine the value of a therapeutic trial rabeprazole over 7 days in detecting pain.Double-blind, randomized, placebo-controlled, crossover study. Patients referred by cardiologist after comprehensive cardiac work-up were enrolled into Oesophageal mucosal disease was determined upper endoscopy...
In a prospective, randomised, double‐blind study of 60 patients who had an elective Caesarean section under spinal anaesthesia we compared 0.1 mg intrathecal morphine with saline placebo. All received intravenously by patient‐controlled analgesia after the operation. Pain, satisfaction and side‐effects were assessed at 4 24 h Pain measured 100‐mm visual analogue scale was less in group both times (p <0.05) consumption lower <0.01). At more pruritus <0.001) but there no difference...
Cognitive load theory, focusing on limits of the working memory, is relevant to medical education; however, factors associated with cognitive during procedural skills training are not well characterized. The authors sought determine how features learners, patients/tasks, settings, and supervisors were three types among learners performing a specific procedure, colonoscopy, identify implications for teaching.Data collected through an electronically administered survey sent 1,061 U.S....
Few studies have investigated cognitive factors affecting learning of procedural skills in medical education. Cognitive load theory, which focuses on working memory, is highly relevant, but methods for measuring during training are not well understood. Using colonoscopy as an exemplar, we used theory to develop a self-report instrument measure three types (intrinsic, extraneous and germane load) provide evidence validity.We developed the (the Load Inventory Colonoscopy [CLIC]) using...
The use of the p-value in quantitative research, particularly its threshold "P < 0.05" for determining "statistical significance," has long been a cornerstone statistical analysis research. However, this standard increasingly scrutinized potential to mislead findings, especially when practical significance, number comparisons, or suitability tests are not properly considered. In response controversy around p-values, American Statistical Association published statement 2016 that challenged...
Introduction. Objective Structured Clinical Examinations (OSCEs) are widely used to assess medical students' communication skills, but scoring interview-based assessments is time-consuming and potentially subject human bias. This study explored the potential of large language models (LLMs) automate OSCE evaluations using Master Interview Rating Scale (MIRS). Methods. We compared performance four state-of-the-art LLMs (GPT-4o, Claude 3.5, Llama 3.1, Gemini 1.5 Pro) in evaluating transcripts...
Inflammatory bowel disease (IBD) is increasingly common among non-Caucasian populations, but interracial differences in characteristics and management are not well-characterized. We tested the hypothesis that vary by race IBD patients an ethnically diverse healthcare system. A retrospective study of safety net system San Francisco, CA, from 1996 to 2009 was undertaken. Patient records with International Classification Diseases, 9th Revision (ICD9) codes 555.xx, 556.xx, 558.xx were reviewed....

Rates of inflammatory bowel disease (IBD) appear to be increasing among nonwhite populations outside the United States, but national data describing incidence and prevalence IBD are not available for minority patients. The aim this study was examine time trends hospital discharge patients with IBD.Nationally representative discharges were obtained from National Hospital Discharge Survey years 1994 2006. Race-specific annual proportions hospitalizations including a diagnosis ulcerative...
Demand for endoscopic procedures scheduled with anesthesia is increasing and no-show to appointments carries significant patient health financial impact, yet little known about predictors of no-show. We performed a 16-month retrospective observational cohort study patients outpatient endoscopy at county hospital serving the safety-net healthcare system San Francisco. Multivariate logistic regression analysis was evaluate associations between attendance In total, 511 underwent during period....
Health-care disparities exist for patients of minority race and low socioeconomic status (SES) in many chronic disease states, but little is known regarding health-care with inflammatory bowel (IBD). Using nationally representative data, we sought to determine whether use immunomodulators anti-tumor necrosis factor (TNF) agents differed by race/ethnicity SES among ambulatory IBD.We used data from the National Ambulatory Medical Care Survey Hospital 1998 2010. We identified visits associated...
Although autoimmune hepatitis (AIH) is more common in women and affects people of all races/ethnicities, there currently limited information regarding the relationship between race/ethnicity AIH, especially context underserved populations. We aim to evaluate AIH better characterize its clinical features among different racial groups. conducted a 15-year retrospective analysis, from January 2002 June 2017, patients seen at Zuckerberg San Francisco General Hospital (ZSFG).

Abstract Objectives Cognitive load theory (CLT) focuses on the limited bandwidth of working memory. Core to CLT is concept cognitive overload, which occurs when memory demands exceed capacity, and learning performance suffer. Within health professions education (HPE), workplace settings are very complex, placing learners at high risk overload. Although continuous monitoring physiologic parameters can indicate states load, how practically identify cognitively overloaded within everyday not...
