Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Membrane Vesicles Can Contribute to Cellulose Degradation by Teredinibacter turnerae, a Cultivable Intracellular Endosymbiont of Shipworms.

Teredinibacter turnerae is a cultivable cellulolytic Gammaproteobacterium (Cellvibrionaceae) that commonly occurs as an intracellular endosymbiont in the gills of wood-eating bivalves of the family Teredinidae (shipworms). The genome of T. turnerae encodes a broad range of enzymes that deconstruct cellulose, hemicellulose and pectin and contribute to wood (lignocellulose) digestion in the shipworm gut.

Music to Their Ears: Reducing Antipsychotic Use With a Personalized Music Intervention for Rural Veterans.

Background This project investigates a music intervention to deprescribe antipsychotics in rural Veterans with dementia.  Methods The Veterans Health Administration Home-Based Primary Care Program is care provided in the home by an interdisciplinary team with the goals of decreasing hospitalizations and falls, providing education to patients and caregivers, and improving quality of life. Eighteen Home Based Primary Care Veterans with dementia and active antipsychotic prescriptions were identified with the goal to deprescribe antipsychotics in 50% of them using a music intervention.

Navigating COPD in Aging Populations: Insights Into Pathophysiology and Comprehensive Care.

Chronic obstructive pulmonary disease (COPD) poses a significant and growing health burden among aging populations, marked by increasing prevalence and complex management challenges specific to elderly patients. This review explores the multifaceted interplay between COPD and aging, highlighting overlapping pathophysiological processes and comorbidities that complicate diagnosis and treatment. We examine age-specific management strategies, emphasizing the need for tailored approaches that account for the unique physical, cognitive, and health-related quality of life impacts on older adults.
