Objective: Concussion symptoms can be clustered into domains and understanding how multiple symptom domains present clinically may guide more accurate interventions. We investigate the associations between concurrent symptom domains and clinical recovery outcomes, as well as the role of sex in these relationships.
Methods: We analysed data from the Ivy League-Big Ten Epidemiology of Concussion Study and included sport-related concussions (SRC) across five academic years 2015-2016/2019-2020 with complete data (n=1160).
Objective: Describe the factor structure of the 22-symptom Sport Concussion Assessment Tool (SCAT), using confirmatory factor analysis (CFA) for a priori hypothesized symptom domains.
Study Design: Prospective observational study.
Setting/participants: Collegiate student-athletes with concussion.
Purpose: To evaluate outer retinal organization in normal subjects and those using hydroxychloroquine (HCQ) with ultrahigh resolution visible light optical coherence tomography (VIS-OCT).
Methods: Forty eyes of 22 adult subjects were recruited from a tertiary care retina practice including controls (20 eyes, 12 subjects, mean age 40±22yrs, mean logMAR BCVA 0.19, 90% female) and subjects with a history of HCQ use (20 eyes, 10 subjects, mean age 62±17yrs, mean logMAR BCVA 0.
Background: Growing interest has motivated recent studies to examine differences in recovery after sport-related concussion (SRC) by sex. However, heterogeneity in study design, participants, and recovery outcomes has led to mixed findings. Further work is needed to evaluate potential differences by sex and to investigate the role of related characteristics, such as sport contact-level, in recovery timelines.

- Traumatic brain injury (TBI) is often overlooked in civilian women, with existing definitions from the CDC and DOD/VA focusing mainly on athletes and military personnel.
- This study analyzed electronic health records to compare these definitions and introduced a new, broader definition called the Penn definition to better identify TBI cases in women.
- The results showed that the Penn definition identified nearly twice as many TBI patients compared to the existing definitions, allowing for more comprehensive research on this condition.
