Living with COPD and its psychological effects on participating in community-based physical activity in Brazil: a qualitative study. Findings from the Breathe Well group.

Physical activity (PA) improves dyspnoea, psychological wellbeing and quality of life (QoL) for people with COPD reducing their risk of exacerbation. However, engagement in PA is low especially amongst those with anxiety and depression, and PA programmes are limited in countries with limited resources such as Brazil. We explored perceptions of 21 people with COPD about the impact of their disease on taking part in community-based PA programmes in Sao Paulo, Brazil through semi-structured telephone interviews from October 2020 to April 2021.

Strengthening Clinician-Researchers' Communication and Knowledge Translation Skills: An Innovative Game Model From the Breathe Well Group.

Communication is a core component of a clinician's role; however, when clinicians conduct research, communicating the emerging findings and recommendations to different types of stakeholders can be unfamiliar territory. Communicating research to advocate for change can be even more challenging. Clinician researchers seeking to be agents for change need to conceive and craft specific, evidence-based messages and communicate these effectively to different stakeholders to negotiate action.

Prediction of mortality among severely injured trauma patients A comparison between TRISS and machine learning-based predictive models.

Background: Given the huge impact of trauma on hospital systems around the world, several attempts have been made to develop predictive models for the outcomes of trauma victims. The most used, and in many studies most accurate predictive model, is the "Trauma Score and Injury Severity Score" (TRISS). Although it has proven to be fairly accurate and is widely used, it has faced criticism for its inability to classify more complex cases.

The prevalence of early contained vascular injury of spleen.

Contained vascular injuries (CVI) of spleen include pseudoaneurysms (PSA) and arterio-venous fistulae (AV-fistulae), and their reported prevalence varies. Our purpose was to assess the prevalence of early splenic CVI seen on admission CT in patients with splenic trauma admitted to a single level 1 trauma center in 2013-2021, and its detection in different CT protocols. A retrospective, single-center longitudinal cohort study.
