Aim: To study the safety and utility of performing an oesophago-gastro-duodenoscopy (EGD) in the setting of an acute myocardial infarction (AMI).
Methods: Case records of all patients who underwent an EGD for various indications within 4 weeks of an AMI between January 2001 and April 2006 were analyzed. Demographic data, indications for endoscopy, outcomes and complications were noted. Main outcome measures included safety and utility of endoscopy in AMI.
Results: A total of 87 EGDs were performed on 85 patients with AMI. Seventy (83%) patients had a non-ST elevation MI, whereas 15 (17%) had ST elevation MI. Mean time between EGD and AMI was 6+/-1.8 days. Indications for EGD were hematemesis and/or melena on presentation in 38 (44.7%), hematemesis and/or melena post anticoagulation in 27 (31.8%). EGD findings were gastric ulcer/erosions in 30 (34%), oesophago-gastric varices in 20 (22%), erosive oesophagitis in 17 (20%) and duodenal ulcer in 11 (13%). Diagnostic yield of EGD was 88%. Endoscopic interventions were performed in 26 (30%) patients with high risk of bleeding lesion. There were no EGD-related mortality, whereas 14 patients re-bled. A total of 21 patients died, including 7/14 (50%) who re-bled, compared with 14/71 (19%) without rebleed (P=0.008). There were no EGD-related deaths. Fourteen patients were on mechanical ventilation and 6/14 (43%) of these died as compared with 15/88 (17%) who were not ventilated (P=0.027).
Conclusion: EGD is safe and useful in diagnosis and management of gastrointestinal hemorrhage in patients with AMI, and allows decisions about anticoagulation. Re-bleed and need for mechanical ventilation predicts poor outcome in these patients.

Background: To identify the relationship between BMI or lipid metabolism and diabetic neuropathy using a Mendelian randomization (MR) study.
Methods: Body constitution-related phenotypes, namely BMI (kg/m), total cholesterol (TC), and triglyceride (TG), were investigated in this study. Despite the disparate origins of these data, all were accessible through the IEU OPEN GWAS database ( https://gwas.
Evaluation of an enhanced ResNet-18 classification model for rapid On-site diagnosis in respiratory cytology.

Department of Pathology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, 325000, Zhejiang, China.
Objective: Rapid on-site evaluation (ROSE) of respiratory cytology specimens is a critical technique for accurate and timely diagnosis of lung cancer. However, in China, limited familiarity with the Diff-Quik staining method and a shortage of trained cytopathologists hamper utilization of ROSE. Therefore, developing an improved deep learning model to assist clinicians in promptly and accurately evaluating Diff-Quik stained cytology samples during ROSE has important clinical value.

Background: Human placental hydrolysate (hPH) contains anti-inflammatory substances. This study aimed to analyze whether injecting hPH into the subacromial space could reduce pain in patients with shoulder impingement syndrome.
Methods: This single-blind, randomized controlled study enrolled 50 patients with shoulder impingement syndrome who were randomly assigned to either the hPH or placebo groups.
Development of a Preliminary Patient Safety Classification System for Generative AI.
BMJ Qual Saf
January 2025
National Center for Human Factors in Healthcare, MedStar Health Research Institute, Washington, District of Columbia, USA.
Generative artificial intelligence (AI) technologies have the potential to revolutionise healthcare delivery but require classification and monitoring of patient safety risks. To address this need, we developed and evaluated a preliminary classification system for categorising generative AI patient safety errors. Our classification system is organised around two AI system stages (input and output) with specific error types by stage.

External quality assessment (EQA) enhances patient safety through the evaluation of the quality of laboratory-based and point of care testing. Regulatory agencies and accreditation organizations utilize the results and the laboratory's response to them as part of assessing the laboratory's fitness to practice. In addition, where EQA samples are commutable and the assigned value has been determined using reference measurement procedures (RMPs), EQA data contributes to the verification of metrological traceability of assays as part of the post-market surveillance of diagnostic (IVD) medical devices (IVD-MDs).
