The delivery of a high and consistent [Formula: see text] is imperative to treat acute hypoxemia. The objective of this study was to analyze the effective inspired oxygen concentration delivered by different low-flow oxygen therapy systems challenged with different oxygen flows and respiratory patterns in an experimental lung model. ⋯ Lung oxygen concentration values delivered by the double-trunk mask were higher than those obtained with other oxygen delivery systems, especially when leaks were present.

Observational Study
Physical Activity and Sedentary Behavior in Adults With Cystic Fibrosis: Association With Aerobic Capacity, Lung Function, Sleep, Well-Being, and Quality of Life.
Physical activity (PA) and sedentary behavior (SB) have marked impact on key prognostic indicators such as aerobic capacity and lung function in people with cystic fibrosis (CF) and may have associations with sleep, well-being, and health-related quality of life (HRQOL). ⋯ Most participants did not meet PA targets. PA levels correlated to aerobic capacity, FEV1, and self-reported sleep quality, and this should be considered in longitudinal studies and in PA interventions.

Review Meta Analysis
Pulmonary Rehabilitation for Patients After COPD Exacerbation.
The aim of this study was to clarify the effectiveness of pulmonary rehabilitation in patients after exacerbations of COPD and to explore the initiation timing of pulmonary rehabilitation. ⋯ Pulmonary rehabilitation showed short-term effects for subjects with exacerbations of COPD even if initiated within 1 week; however, further study is required to determine its long-term effects.

Although prior studies have established the association of asthma with smoking and obesity, literature on difference-in-differences analyses involving sexual identity is sparse. Therefore, this study aimed to examine the between and within sexual identity-group differences in asthma prevalence among individuals who smoke and are obese. ⋯ Smoking and obesity show heightened odds for asthma, with significant odds for sexual minorities in asthma diagnosis relative to heterosexuals. These findings provide formative information for future longitudinal and experimental studies to explore these mechanisms of asthma risks among sexual and gender minorities.
