Adherence to Accelerometer Use in Older Adults Undergoing mHealth Cardiac Rehabilitation: Secondary Analysis of a Randomized Clinical Trial

Background: Wearable accelerometers, which continuously record physical activity metrics, are commonly used in mobile health–enabled cardiac rehabilitation (mHealth-CR). The association between adherence to accelerometer use during mHealth-CR and improvement in clinical outcomes, such as functional capacity, is understudied. The emergence of artificial intelligence (AI) technology provides novel opportunities to investigate accelerometry use patterns in relation […]

Machine Learning in the Prediction of Venous Thromboembolism: Systematic Review and Meta-Analysis

Background: With the increasing use of machine learning (ML)-based risk prediction models for venous thromboembolism (VTE) in patients, the quality and applicability of these models in practice and future research remain unknown. The prediction mechanism of ML and the number of selected factors have been research hotspots in VTE prediction. Objective: To systematically review the […]

Researchers are getting organoids pregnant with human embryos

At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining of the uterus and then grips tight, burrowing in as the first tendrils of a future placenta appear.  This is implantation—the moment that pregnancy officially begins. Only none of it is happening inside a […]

Characterizing Digital Communication Device Use Among Young People From 4 European Countries: Cross-Sectional Survey Study

Background: Digital communication device use is changing rapidly among young people, and current research on this topic is limited or outdated. Objective: We aimed to describe the use of digital communication devices of young people from four European countries and investigate its socioeconomic and demographic characteristics. Methods: In 2023, we administered an online survey to […]
