Objective: To evaluate the association of leisure-time physical activity and sedentary behavior with body image concern and satisfaction in Brazilian adolescents.
Methods: Data were extracted from the 2015 Brazilian National Adolescent School-based Health Survey (Pesquisa Nacional de Saúde do Escolar [PeNSE]). Information regarding body image concern and satisfaction, as well as exposures (physical activity and sedentary behavior) and covariates (maternal education, age, smoking, and alcohol intake), were assessed through a questionnaire.
Results: Logistic regression analysis revealed that engagement in recommended levels of physical activity (≥ 300 min/week) was associated with a decreased concern with body image and a high satisfaction in boys. Four or more hours spent in sedentary activities were associated with increased concern with body image and dissatisfaction among boys and girls.
Conclusion: These findings support the relevance of programs aiming to promote physical activity and reduce sedentary behavior in the adolescent population. Such programs play a protective role against body dissatisfaction and are important for the development of a healthy body image in adolescence.

Unsupervised domain adaptation teacher-student network for retinal vessel segmentation via full-resolution refined model.

Retinal blood vessels are the only blood vessels in the human body that can be observed non-invasively. Changes in vessel morphology are closely associated with hypertension, diabetes, cardiovascular disease and other systemic diseases, and computers can help doctors identify these changes by automatically segmenting blood vessels in fundus images. If we train a highly accurate segmentation model on one dataset (source domain) and apply it to another dataset (target domain) with a different data distribution, the segmentation accuracy will drop sharply, which is called the domain shift problem.

Department of Emergency Medicine, Rush University Medical Center, Chicago, Illinois.
Importance: Lung ultrasound (LUS) aids in the diagnosis of patients with dyspnea, including those with cardiogenic pulmonary edema, but requires technical proficiency for image acquisition. Previous research has demonstrated the effectiveness of artificial intelligence (AI) in guiding novice users to acquire high-quality cardiac ultrasound images, suggesting its potential for broader use in LUS.
Objective: To evaluate the ability of AI to guide acquisition of diagnostic-quality LUS images by trained health care professionals (THCPs).

This study examined how postpartum mothers experience social media within the context of mothering and their postpartum body. A subsample of 20 mothers (age 23-42) of infants aged 0-6 months who were exposed to body-focused social media posts as part of an experimental study designed to test social media's impact on body dissatisfaction took part in semi-structured interviews. We used thematic analysis to identify themes and subthemes generated from the data.
