Physical activity and quality of life among breast cancer survivors: Pink SWAN.

Purpose: To describe physical activity (PA) trajectories across 10 years post-breast cancer diagnosis and examine their association with quality of life (QoL).

Methods: Participants from the longitudinal Study of Women's Health Across the Nation who developed incident breast cancer completed the Quality of Life in Adult Cancer Survivors scale (QLACS) which has 12 domains. Breast cancer survivors (BCS) with at least one post-diagnosis measure of the Kaiser Physical Activity Survey (PA) were included (n = 96).

FAF2 is a bifunctional regulator of peroxisomal homeostasis and saturated lipid responses.

Exposure to saturated fatty acids (SFAs), such as palmitic acid, can lead to cellular metabolic dysfunction known as lipotoxicity. Although canonical adaptive metabolic processes like lipid storage or desaturation are known cellular responses to saturated fat exposure, the link between SFA metabolism and organellar biology remains an area of active inquiry. We performed a genome-wide CRISPR knockout screen in human epithelial cells to identify modulators of SFA toxicity.

Development of a physical performance summary score in middle age: Findings from the CARDIA Function study.

Few physical performance batteries exist that appropriately evaluate physical limitations in middle-aged adults. We aimed to develop a physical performance summary score that is appropriate for use in epidemiology studies of middle-aged adults using data from the Coronary Artery Risk Development in Young Adults (CARDIA) Function study, which assessed self-reported function (PROMIS-SF20a) and physical performance measures (gait speed, balance, lower-body strength, grip strength, and cardiovascular endurance). The CARDIA Physical Performance (CAPP) score was developed using sex-specific quartiles, assigning points based on these quartiles (0 for not attempted, 1-4 for each quartile), and summing points across all performance measures (0-20, higher scores reflect greater performance).

Community-Engaged Development of a Nutrition Curriculum: The Go Healthy Indigenous-Supported Agriculture Study.

Objective: To understand how Osage Nation community members define healthy eating and develop a corresponding nutrition curriculum through community engagement.

Design: This project comprised a concurrent embedded mixed methods group concept mapping (GCM) study followed by focus group discussions (FGD) to provide feedback on a nutrition curriculum.

Setting: Osage Nation, Oklahoma.
