Correlation Between Handgrip Strength and Bone Density and Fragility Fracture Risk Among Older Adults: A Cross-Sectional Study.
J Nurs Res
January 2025
Department of Medical Research, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan.
Background: Population aging has led to a surge in elderly care needs worldwide. Bone aging, skeletal muscle degeneration, and osteoporosis pose critical health challenges for the elderly. The process of bone and skeletal muscle aging not only impacts the functional abilities but also increases fragility fracture risk.

BACKGROUND Infection is a cause of morbidity and mortality in solid-organ transplantation (SOT). We evaluated a new score that is applied during the first month after transplantation. The score comprises biomarkers of innate and acquired immunity to predict infections in SOT.

Background: The topic of the effect of the patient table on attenuation in myocardial perfusion imaging (MPI) SPECT is gaining new relevance due to deep learning methods. Existing studies on this effect are old, rare and only consider phantom measurements, not patient studies. This study investigates the effect of the patient table on attenuation based on the difference between reconstructions of phantom scans and polar maps of patient studies.

Unlabelled: Right-to-left shunt may be a cause of paradoxical embolization (and cryptogenic cerebral ischemic events). Patent foramen ovale and pulmonary arterio-venous malformations are the most common cause of paradoxical embolization; however, some rare cardiovascular lesions may cause a right-to-left shunt with consequent paradoxical embolization. We describe a case of a young child with superior sinus venosus atrial septal defect who underwent surgical closure and developed a cryptogenic cerebral ischemic attack due to a rare cause of paradoxical embolization, during a long-term follow-up.
View Article and Find Full Text PDFCardiac chambers emerge from a heart tube that balloons and bends to create expanded ventricular and atrial structures, each containing a convex outer curvature (OC) and a recessed inner curvature (IC). A comprehensive understanding of the cellular and molecular mechanisms underlying the formation of these characteristic curvatures remains lacking. Here, we demonstrate in zebrafish that the initially similar populations of OC and IC ventricular cardiomyocytes diverge in the organization of their actomyosin cytoskeleton and subsequently acquire distinct OC and IC cell shapes.
