Development and Validation of an Interpretable Machine Learning Model for Osteoporosis Prediction Using Multimodal Musculoskeletal Ultrasound and Clinical Features

Objectives This study aimed to develop and validate an interpretable machine learning model for osteoporosis prediction based on multimodal ultrasound and clinical features. Methods Participants with suspected osteoporosis were enrolled from 2 medical centers. Clinical variables...

Three-decade trends in nonalcoholic fatty liver disease across 204 countries and territories

Nonalcoholic fatty liver disease (NAFLD) has emerged as a leading chronic liver disease globally, driven by the rising incidence of obesity, type 2 diabetes, and metabolic syndrome. Despite the increasing burden, most studies focus on prevalence rather than incidence, leaving a g...

Suspended patient-specific instrument-assisted femur-first osteotomy for fixed-bearing unicompartmental knee arthroplasty: technical note and preliminary clinical results

This study designed a novel suspended patient-specific instrument (SPSI), described its design rationale and the surgical workflow of femur-first osteotomy based on this instrument, and explored its feasibility and early clinical outcomes in fixed-bearing unicompartmental knee ar...

Association between cardiometabolic index and incident electrocardiographic abnormalities in older adults

Electrocardiographic (ECG) abnormalities are important predictors of cardiovascular events in older adults, yet their early identification remains challenging. The cardiometabolic index (CMI), which integrates central obesity and lipid metabolism, has emerged as a potential marke...

Stepwise diagnosis and minimally invasive management of obscure gastrointestinal bleeding secondary to a Meckel’s diverticulum: a case report

Abstract Background Obscure gastrointestinal bleeding (OGIB) presents a significant diagnostic challenge for clinicians due to the anatomical characteristics and inaccessibility of the small intestine. Preoperative diagnosis is particularly challenging, and optimal management rel...
