Associations between early trajectories of amygdala development and later school-age anxiety in two longitudinal samples.

Amygdala function is implicated in the pathogenesis of autism spectrum disorder (ASD) and anxiety. We investigated associations between early trajectories of amygdala growth and anxiety and ASD outcomes at school age in two longitudinal studies: high- and low-familial likelihood for ASD, Infant Brain Imaging Study (IBIS, n = 257) and typically developing (TD) community sample, Early Brain Development Study (EBDS, n = 158). Infants underwent MRI scanning at up to 3 timepoints from neonate to 24 months. Anxiety was assessed at 6-12 years. Linear multilevel modeling tested whether amygdala volume growth was associated with anxiety symptoms at school age. In the IBIS sample, children with higher anxiety showed accelerated amygdala growth from 6 to 24 months. ASD diagnosis and ASD familial likelihood were not significant predictors. In the EBDS sample, amygdala growth from birth to 24 months was associated with anxiety. More anxious children had smaller amygdala volume and slower rates of amygdala growth. We explore reasons for the contrasting results between high-familial likelihood for ASD and TD samples, grounding results in the broader literature of variable associations between early amygdala volume and later anxiety. Results have the potential to identify mechanisms linking early amygdala growth to later anxiety in certain groups.

Faculty bridging individual and organizational resilience: results of a qualitative analysis.

BACKGROUND: Medical student burnout and anxiety has received growing attention in the past decade. The culture of competition and assessment has resulted in increasing stress levels amongst medical students, causing a decline in their academic performance and overall mental health. The objective of this qualitative analysis was to characterize recommendations from educational experts to aid students' academic progress. METHODS: At an international meeting in 2019, worksheets were completed by medical educators during a panel discussion. Participants responded to four scenarios representing common challenges medical students face in school (eg. Postponing Step 1, failing clerkships, etc.). For each case, participants addressed what students, faculty and medical schools could do to mitigate the challenge. Inductive thematic analysis was conducted by two authors followed by deductive categorization using an individual-organizational resilience model. RESULTS: Across the four cases, common suggestions made for students, faculty and medical schools were aligned to a resilience model representing the complex interplay between individuals and organizations and the impact on student wellbeing. DISCUSSION: Using suggestions from medical educators from across the US, we were able to identify recommendations for students, faculty, and medical schools to help students succeed in medical school. By applying a model of resilience, faculty serve as a critical bridge to connect students to the medical school administration. Our findings also support a pass/fail curriculum to ease the competition and burden students place on themselves.
