Performance of Black and Indigenous applicants in a medical school admissions process.

Background: Diversity in medical schools has lagged behind Canada's growing multicultural population. Dalhousie medical school allows Black and Indigenous applicants to self-identify. We examined how these applicants performed and progressed through the admissions process compared to Other group (applicants who did not self-identify).

Sleep Parameters and Overnight Urinary Melatonin Production in Children With Persistent Post-concussion Symptoms.

Background: Sleep disturbance is common after a mild traumatic brain injury (mTBI) in children, yet its biology is poorly understood. We aimed to explore sleep-related problems (SRPs), sleep-activity patterns, and endogenous melatonin production in children with different recovery trajectories following mTBI. We hypothesized that children with delayed recovery would have more SRPs and abnormal sleep-activity patterns, which would correlate with lower overnight melatonin production.
