There is a lack of evidence-based treatment standards for low-velocity gunshot wounds (GSW). This review focuses on the best available evidence for the management of civilian, low velocity GSWs to an extremity.

When comparing three commercially available hs-cTn assays, results differed dramatically from one assay to another. The difference was great enough to impact patient care decisions, such as admission, discharge, or further testing.

Febrile infants <90 days who were COVID positive had lower rates of serious bacterial infection (SBI) when compared to age and gender matched COVID negative febrile infants.

Medical students felt more confident in rapidly assessing patients after a single shift in ED triage in which they repeatedly performed quick screening exams.
