Low Risk of Cardiac Complications in Collegiate Athletes After Asymptomatic or Mild COVID-19 Infection.

Objective: The objective of this study was to determine the utility of "standard" cardiac screening with EKG, echocardiography, and serum troponin T (hs-Tn T) testing after COVID infection in competitive college athletes.

Design: Prospective cohort study.

Setting: Tertiary cardiology clinic, university training room.

Variability and trends in corticosteroid use by male United States participants with Duchenne muscular dystrophy in the Duchenne Registry.

Background: Treatment options for Duchenne muscular dystrophy remain limited, although consensus treatment guidelines recommend corticosteroid use.

Methods: This retrospective analysis assessed corticosteroid use in ambulatory and nonambulatory US males with Duchenne, age 35 and under, or Becker muscular dystrophy, who enrolled in The Duchenne Registry from 2007 to 2016 (formerly DuchenneConnect).

Results: The mean (SD) age of corticosteroid use initiation was 5.
