Beyond our "ancient roots": Toward a broader understanding of the motivational power of societal meta-narratives.

The "historical myths" addressed in the target article are but one type of societal meta-narrative, a cognitive framework for understanding the story of one's group: Its origins, purpose, turning points, threats and opportunities, key relationships, and the appropriate affect for group members. Engagement with the broader literature on meta-narratives, including political and sacred myths, and on group entitativity is recommended.

Vcam1+ Fibro-adipogenic Progenitors Mark Fatty Infiltration in Chronic Limb Threatening Ischemia.

Skeletal muscle health and function is a critical determinant of clinical outcomes in patients with peripheral arterial disease (PAD). Herein, we identify fatty infiltration, the ectopic deposition of adipocytes in skeletal muscle, as a histological hallmark of end-stage PAD, also known as chronic limb threatening ischemia (CLTI). Leveraging single cell transcriptome mapping in mouse models of PAD, we identify a pro-adipogenic mesenchymal stromal cell population marked by expression of Vcam1 (termed Vcam1+ FAPs) that expands in the ischemic limb.

Cost-effectiveness of Intervention Implementation Support for Reducing Eating Disorder Symptoms Among College Students.

Implementation support for prevention interventions is receiving increased attention, as many organizations receive training in evidence-based practices but do not deliver the interventions optimally. The Body Project, a four-session program, significantly reduces eating disorder symptoms and future disorder onset among group participants when delivered by peer educators at colleges/universities. Costs and cost-effectiveness of the program were examined using data from a randomized trial that compared three levels of implementation support at 63 colleges: (1) a train-the-trainer (TTT) workshop alone, (2) TTT plus a technical assistance (TA) workshop, or (3) TTT plus TA plus monthly quality assurance (QA) consultations.

Factors Associated with Provider Practices Related to Infant Feeding in Primary Care Settings: Results from a Pilot Survey.

In 2020, only 25.6% of dyads in the US were exclusively breastfeeding at six months. Previous research has shown that breastfeeding continuation improves when patients receive both prenatal and postpartum support.
