"Oh, you're my health care provider?" Recounting the experiences of people of African descent in Nova Scotia pursuing or working in health professions.

BACKGROUND: Increasing, supporting and cultivating diversity in health programs is key to addressing health inequities. We sought to investigate barriers and facilitators that could affect enrolment and success in health professions among people of African descent in Nova Scotia, Canada. METHODS: We conducted semistructured interviews with people who self-identified as being of African descent who resided or grew up in Nova Scotia, who were working in or pursuing a career in a health profession, and who had participated in culturally specific mentorship programs. Semistructured interviews explored participant experiences that shaped their pursuit of a health profession, as a person of African descent. We thematically analyzed transcribed interviews using constructivist grounded theory. RESULTS: We interviewed 23 participants. Thematic coding showed 4 major themes. The theme of "stand on my shoulders" spoke to the importance of mentorship within the Black community. "Growing through pain" spoke to resilience amidst race-related challenges. "Never the student; ever the teacher" showed the repeated need to educate on issues of race or diversity. The final theme, "change," highlighted next steps, including the need for improvement in curricula, for development of Black faculty and for initiatives that offer support. INTERPRETATION: We found that mentorship, particularly within the community, was instrumental to promoting feelings of belonging. However, participants described the need for resilience in the face of discrimination during training and in practice in health care professions. Rather than focusing on their education, many had to educate those around them. Increased representation, support programs and updated curricula are needed to promote change.

N2b Reflects the Cognitive Changes in Executive Functioning After Concussion: A Scoping Review.

Objectives: The N2b is an event-related potential (ERP) component thought to index higher-order executive function. While the impact of concussion on executive functioning is frequently discussed in the literature, limited research has been done on the role of N2b in evaluating executive functioning in patients with concussion. The aims of this review are to consolidate an understanding of the cognitive functions reflected by the N2b and to account for discrepancies in literature findings regarding the N2b and concussion. Methods: A scoping review was conducted on studies that used the N2b to measure cognitive functioning in healthy control populations, as well as in people with concussions. Results: Sixty-six articles that met inclusion criteria demonstrated that the N2b effectively represents stimulus-response conflict management, response selection, and response inhibition. However, the 19 included articles investigating head injury (using terms such as concussion, mild head injury, and mild traumatic brain injury) found widely varied results: some studies found the amplitude of the N2b to be increased in the concussion group, while others found it to be decreased or unchanged. Conclusion: Based on the available evidence, differences in the amplitude of the N2b have been linked to response selection, conflict, and inhibition deficits in concussion. However, due to large variations in methodology across studies, findings about the directionality of this effect remain inconclusive. The results of this review suggest that future research should be conducted with greater standardization and consistency.
