Persistent organic pollutants and fatty acids in humpback whales: Antarctic and Chilean feeding and Brazilian breeding sites.

This study investigated the fatty acid composition and persistent organic pollutant (POP) levels in humpback whales across the Southern Ocean, Chilean and Brazilian coast. We found significant regional variations in both fatty acids and POPs. Whales from the Strait of Magellan exhibited a distinct fatty acid profile, indicative of a specialized diet rich in higher trophic level prey.

Advocating with Community: A Community-Engaged Advocacy Curriculum for Internal Medicine Residents.

Background: In 2022, the Accreditation Council for Graduate Medical Education updated its competencies for residents in all specialties to include health policy advocacy. A recent systematic review shows that while a growing number of residency curricula include policy advocacy, few programs join in policy advocacy efforts with community partners.

Aim: To create a community-engaged advocacy curriculum for residents that is part of a mutually beneficial partnership with community-based organizations (CBOs).

Anthropogenic debris in three sympatric seal species of the Western Antarctic Peninsula.

Litter pollution is a growing concern, including for Antarctica and the species that inhabit this ecosystem. In this study, we investigated the microplastic contamination in three seal species that inhabit the Western Antarctic Peninsula: crabeater (Lobodon carcinophaga), leopard (Hydrurga leptonyx) and Weddell (Leptonychotes weddellii) seals. Given the worldwide ubiquity of this type of contaminant, including the Southern Ocean, we hypothesized that the three seal species would present anthropogenic debris in their feces.

Assessing clinicians' and trainees' knowledge and practice of the IDSA guidelines for asymptomatic bacteriuria in older adults.

A survey of advanced practice clinicians (APCs), physicians, residents, and medical students at an academic medical center and community practices in southeastern Texas revealed a gap in knowledge and practice related to testing and treatment for asymptomatic bacteriuria (ASB) in older adults.
