Abstract To investigate the association and potential causal relationship between accelerometer-assessed physical activity (PA) and the risk of senile cataract (SC). The study population was derived from the UK Biobank database. Triaxial accelerometer data from wearable devices, collected over a continuous 7-day wear period (accounting for potential seasonal variation), were used to define PA at light (LPA), moderate (MPA), and vigorous (VPA) intensities.

Abstract Limited data exist on long-term trajectories of functional scores before and after stroke diagnosis. We analyzed 1325, 754, 3907, and 2902 incident strokes from China Health and Retirement Longitudinal Study (CHARLS), English Longitudinal Study of Ageing (ELSA), Health and Retirement Study (HRS), and Survey of Health, Ageing and Retirement in Europe (SHARE), respectively. Two non-stroke participants were matched to each stroke case by age and gender.

Abstract The rising burden of endocrine and metabolic diseases demands scalable and accessible screening tools. Here we developed Reti-Pioneer, a multitask retinal imaging framework that integrates quality-aware modules with pre-trained foundation models for efficient, multidisease detection.
