A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Longitudinal Echocardiographic Surveillance of Aortic Dilation in a Phenotype‐Enriched Turner Syndrome Cohort

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...
