CONCLUSION: The Koori Quit Pack mailout smoking cessation program was feasible to support Aboriginal and Torres Strait Islander people. The intervention resulted in a high smoking cessation rate and should be upscaled, implemented and evaluated nationally.

We examined whether a community engagement approach and jurisdictional attributes were associated with local action to restrict the sale of flavored tobacco products in Los Angeles County during 2019-2022.

CONCLUSIONS: Competing in an ultra-marathon leads to a transient increase in cardiac injury biomarkers, mild lung-fluid accumulation, and impairments in lung diffusion. Reductions in DLco are predominantly caused by a reduced Vc and possible pulmonary capillary de-recruitment at rest. However, impairments in alveolar-capillary recruitment and Dm both contribute to a fall in exertional DLco following an ultra-marathon. Perturbations in lung diffusion were evident across a range of event distances...
