Physical activity and mental health: a systematic review and best-evidence synthesis of mediation and moderation studies.

Background: While evidence consistently demonstrates that physical activity is beneficial to mental health, it remains relatively unknown how physical activity benefits mental health, and which factors influence the effect of physical activity on mental health. This understanding could vastly increase our capacity to design, recommend, and prescribe physical activity in more optimal ways. The purpose of this study was to systematically review and synthesise evidence of all mediators and moderators of the relationship between physical activity and mental health.

Lessons learned from implementing a Human Factors programme into an NHS trust.

The interest in employing Human Factors (HF) in healthcare is increasing. There are very few papers that outline an approach to embedding the practical application of HF in healthcare and the lessons that can be learned. The SCReaM HF and Team Resource Management (TRM) programme is not only aimed at raising the awareness and understanding of the science of HF within healthcare, but also to embed its practical application to support staff improve their safety and wellbeing and that of their patients.

Large-Scale Study on AI's Impact on Identifying Chest Radiographs with No Actionable Disease in Outpatient Imaging.

Rationale And Objectives: Given the high volume of chest radiographs, radiologists frequently encounter heavy workloads. In outpatient imaging, a substantial portion of chest radiographs show no actionable findings. Automatically identifying these cases could improve efficiency by facilitating shorter reading workflows.
