The development of an end-to-end service solution to support lupus patients and improve their experience in clinical trials.

Objective: To develop an end-to-end clinical trial service to improve patient experience during trials, reduce the burden of participating in a trial, and increase trial retention.

Methods: A literature search and stakeholder interviews were used to identify current challenges and unmet needs of systemic lupus erythematosus patients and other systemic lupus erythematosus clinical trial stakeholders. The results from the literature search and interviews were used to create a five-phase map describing the current clinical trial experience of all stakeholders.

Physical activity intensity, bout-duration, and cardiometabolic risk markers in children and adolescents.

Objectives: To determine the role of physical activity intensity and bout-duration in modulating associations between physical activity and cardiometabolic risk markers.

Methods: A cross-sectional study using the International Children's Accelerometry Database (ICAD) including 38,306 observations (in 29,734 individuals aged 4-18 years). Accelerometry data was summarized as time accumulated in 16 combinations of intensity thresholds (≥500 to ≥3000 counts/min) and bout-durations (≥1 to ≥10 min).
