Review Meta Analysis
Sensitivity of diffusion-weighted magnetic resonance imaging in transient global amnesia as a function of time from symptom onset.
The objective was to systematically evaluate the sensitivity of diffusion-weighted magnetic resonance imaging (DW-MRI) for transient global amnesia (TGA) across various time frames compared to the reference-standard clinical criteria. ⋯ DW-MRI lesions are uncommon in patients with TGA early after symptom onset, but the sensitivity (i.e., positivity rate) of DW-MRI increases with time. Despite the limited quality of existing evidence, obtaining an early DW-MRI in patients with clinical diagnosis of TGA in the acute setting is likely a low-yield test.

Observational Study
Resource utilization and outcomes among children risk stratified by pediatric appendicitis risk calculator (pARC) at a tertiary pediatric center.
Appendicitis is a common pediatric condition requiring surgery. The pediatric appendicitis risk calculator (pARC) was recently developed to guide clinical care. The objective of this study is to describe resource utilization and clinical outcomes among children with appendix ultrasound (US) scans risk stratified by pARC score. ⋯ There is a high rate of resource utilization among patients who are low appendicitis risk by pARC score. Outcome variation by pARC scores presents future opportunity to selectively reduce resource utilization in pediatric patients.
