RESUMEN
PURPOSE: Doctors of Tomorrow (DoT) is a pipeline program between the University of Michigan Medical School and Cass Technical High School in Detroit where the overall mission is to encourage youth from communities that are underrepresented in medicine to pursue their interests in healthcare careers. Students have the opportunity to apply for a summer internship between 9th grade and 10th grade. There is limited literature on the effectiveness of experiential-learning opportunities in pipeline programs to support development of personal and professional skills. The purpose of this study was to examine the experiences of students participating in the DoT summer internship program in order to better understand how their engagement influenced personal and professional development. METHOD: An exploratory qualitative study was conducted using responses from 27 students who participated in the DoT summer internship program between 2014 and 2018. Students engaged in self-reflective practices prompted by weekly surveys. Data were analyzed through an inductive process by coding and thematic analysis. RESULTS: Four overarching themes were identified: (1) engagement in authentic experiential-learning opportunities; (2) development of professional skills; (3) self-reflection and actualization; and (4) real world barriers in experiential-learning. CONCLUSIONS: High school students engaged in a variety of different community internships and shared insights that illustrated depth and diversity of understanding health in their community. Their reflections illustrate the added value of experiential-education in pipeline programs.

INTRODUCTION: Altered DNA methylation (DNAm) levels of hypothalamic-pituitary-adrenal (HPA) axis genes has been associated with exposure to childhood maltreatment (CM) and depression; however, it is unknown whether CM and depression have joint and potentially interacting effects on the glucocorticoid receptor (NR3C1) DNAm. We investigated the impact of CM and lifetime major depressive disorder (MDD) on NR3C1 DNAm and gene expression (GE) in 147 adult participants from the Detroit Neighborhood Health Study. METHODS: NR3C1 promoter region DNAm was assessed via pyrosequencing using whole blood-derived DNA. Quantitative RT-PCR assays measured GE from leukocyte-derived RNA. Linear regression models were used to examine the relationship among CM, MDD, and DNAm. RESULTS: Both CM and MDD were significant predictors of NR3C1 DNAm: CM was associated with an increase in DNAm in an EGR1 transcription factor binding site (TFBS), whereas MDD was associated with a decrease in DNAm downstream of the TFBS. No significant CM-MDD interactions were observed. CM alone was associated with significantly lower NR3C1 GE. LIMITATIONS: Our report of CM is a retrospective self-report of abuse, which may introduce recall bias. DNAm was measured in whole blood and may not reflect brain-derived DNAm levels. CONCLUSIONS: CM and MDD are both associated with altered DNAm levels in the NR3C1 promoter region, however the location and direction of effects differ between the two exposures, and the functional effects, as measured by GE, appear to be limited to CM exposure alone. CM exposure may be biologically embedded in this key HPA axis gene.
