Clerkship Students' Use of Clinical Reasoning Concepts After a Pre-clinical Reasoning Course.

Background: Many medical schools have incorporated clinical reasoning (CR) courses into their pre-clinical curricula to address the quality and safety issue of diagnostic error. It is unknown how students use concepts and practices from pre-clinical CR courses once in clerkships.

Objective: We sought to understand how students utilize CR concepts from a pre-clinical course during clerkships and to identify facilitators and barriers to the use of reasoning concepts.

Impact of tent shade on heat exposures and simulated heat strain for people experiencing homelessness.

Concurrent increases in homelessness and heat intensity, duration, and frequency translate to an urban heat risk trap for the unsheltered population. Homelessness is both a driver and consequence of poor health, co-creating distinct geographies with various risk factors that exacerbate heat vulnerability. We tested the efficacy of different tent shadings over identical tents often observed in the Phoenix area (white bedsheet, mylar, tarp, and aluminum foil) and compared them to a control tent (uncovered) and ambient conditions.

Guidelines for management of actual or suspected inadvertent intra-arterial injection of sclerosants.

Background: Inadvertent intra-arterial injection of sclerosants is an uncommon adverse event of both ultrasound-guided and direct vision sclerotherapy. This complication can result in significant tissue or limb loss and significant long-term morbidity.

Objectives: To provide recommendations for diagnosis and immediate management of an unintentional intra-arterial injection of sclerosing agents.
