Identifying Community-Built Environment's Effect on Physical Activity and Depressive Symptoms Trajectories Among Middle-aged and Older Adults: Chinese National Longitudinal Study.
JMIR Public Health Surveill
January 2025
Faculty of Human-Environment Studies, Kyushu University, Fukuoka, Japan.
Background: The effects of physical activity (PA) across different domains and intensities on depressive symptoms remain inconclusive. Incorporating the community-built environment (CBE) into longitudinal analyses of PA's impact on depressive symptoms is crucial.
Objective: This study aims to examine the effects of PA at different intensities-low-intensity PA (eg, walking activities) and moderate-to-vigorous-intensity PA (eg, activities requiring substantial effort and causing faster breathing or shortness of breath)-across leisure-time and occupational domains on depressive symptom trajectories among middle-aged and older adults.
Manipulation of Surface Spin Configurations for Enhanced Performance in Oxygen Evolution Reactions.
Nano Lett

studies of the relationship between surface spin configurations and spin-related electrocatalytic reactions are crucial for understanding how magnetic catalysts enhance oxygen evolution reaction (OER) performance under magnetic fields. In this work, 2D FeSe nanosheets with rich surface spin configurations are synthesized via chemical vapor deposition. magnetic force microscopy and Raman spectroscopy reveal that a 200 mT magnetic field eliminates spin-disordered domain walls, forming a spin-ordered single-domain structure, which lowers the OER energy barrier, as confirmed by theoretical calculations.

January 2025
Department of Cardiology, Division of Heart & Lungs, University Medical Center Utrecht, University of Utrecht, Utrecht, The Netherlands.
Background: Hyponatremia is one of the complicating findings in acute decompensated heart failure. Decrease in cardiac output and systemic blood pressure triggers activation of renin-angiotensin-aldosterone system, antidiuretic hormone, and norepinephrine due to the perceived hypovolemia. Fluid-overloaded heart failure patients are commonly treated with loop diuretics, acutely decompensated heart failure patients tend to be less responsive to conventional oral doses of a loop diuretic, while other different diuretics could work in different part of nephron circulation system.

Matern Child Health J
January 2025
Faculty of Medicine, University of Parakou, Parakou, Benin.
Introduction: Globally, the prevalence of undernutrition is highest in the sub-Saharan African region with over a third of the world's stunted children residing in this region. Many studies have explored child nutrition in sub-Saharan Africa, but they often overlook the intricate nuances of maternal knowledge. We examined the association between maternal nutritional knowledge and childhood nutritional outcomes.
