Impact of considering United States Medical Licensing Examination Step 1 pass/fail on diversity in dermatology residency recruitment.

The University of Chicago dermatology residency program considered the United States Medical Licensing Examination (USMLE) Step 1 pass/fail during the 2020-2021 application cycle with the goal of recruiting diverse dermatology residency candidates. We conducted a retrospective multiyear cross-sectional study among applicants to the dermatology residency program during the 2018-2019 and 2020-2021 application cycles, the latter excluding use of USMLE Step 1 cutoff scores as a screening tool. Of the applicants, 69.8% (n = 419) and 94.5% (n = 605) had their residency applications reviewed by our program during the 2018-2019 and 2020-2021 application cycles, respectively. There was a statistically significant upward trend in the number of underrepresented in medicine (URiM) applicants offered an interview from 10.4% (n = 5) to 37.7% (n = 20) across the application cycles. Multiple linear regression demonstrated there was a statistically significant decrease in the mean USMLE Step 1 score among applicants reviewed across application cycle and URiM status independently, and as a factor of their interaction (P = .016 and P = .001). By de-emphasizing the USMLE Step 1 score and using the test as originally intended, a marker for licensure, our program significantly increased the number of URiM applicants who were offered an interview and implemented a holistic review process focused on individual attributes and cultural competence.

Vitiligo-like manifestations of graft-versus-host disease in a pediatric population.

Vitiligo-like changes are an uncommon cutaneous manifestation of graft-versus-host disease (GVHD). We report three cases and review the literature of pediatric patients with vitiligo-like changes associated with GVHD. Improved characterization of this phenomenon may lend insight into the biologic pathways that underlie both vitiligo and GVHD.

Qualitative Study of Interprofessional Collaboration in Radiation Oncology Clinics: Is There a Need for Further Education?

PURPOSE: Interprofessional education (IPE) is gaining recognition as a means of improving health care delivery and patient outcomes. A primary goal of IPE is improved interprofessional collaboration (IPC). The multidisciplinary team in the radiation oncology clinic requires effective IPC for optimal delivery of radiation therapy. However, there are limited data on IPE and IPC in radiation oncology. This qualitative study aims to characterize IPC in radiation oncology. METHODS AND MATERIALS: Semistructured phone interviews were performed from June to August 2019 with radiation oncologists, nurses, dosimetrists, radiation therapists, medical physicists, and medical students across a single academic medical center and affiliated network sites. Interviews were recorded, de-identified, and transcribed verbatim. Resulting transcripts were analyzed using thematic analysis. RESULTS: Seventeen interviews were performed with 4 radiation oncologists, 2 nurses, 2 dosimetrists, 4 radiation therapists, 2 medical physicists, and 3 medical students. Thematic analysis identified 4 themes: (1) management of the radiation oncology clinic, (2) potential impact of interprofessional training in radiation oncology, (3) current climate of interprofessional education in radiation oncology, and (4) creating an interprofessional training program in radiation oncology. Each theme elicited between 2 and 7 subthemes. CONCLUSIONS: From the analytical themes that emerged, it is hypothesized that misunderstanding professionals' roles can lead to communication breakdown, which creates less efficient clinic management and disorganized patient care. Although other medical professionals shadow physicians during their training, physicians are not learning about other professions in the same way. Interviewees from each professional category recommend a formal shadowing program for radiation oncology trainees at the medical student or resident level. Having structured opportunities for IPE is important given competing demands of learners during medical student rotations and residency. This study suggests an unmet need for exposure of radiation oncology medical trainees to IPE with the ultimate goal of improving IPC in the radiation oncology clinic.

Ecstasy (MDMA) Alters Cardiac Gene Expression and DNA Methylation: Implications for Circadian Rhythm Dysfunction in the Heart.

MDMA (ecstasy) is an illicit drug that stimulates monoamine neurotransmitter release and inhibits reuptake. MDMA's acute cardiotoxicity includes tachycardia and arrhythmia which are associated with cardiomyopathy. MDMA acute cardiotoxicity has been explored, but neither long-term MDMA cardiac pathological changes nor epigenetic changes have been evaluated. Microarray analyses were employed to identify cardiac gene expression changes and epigenetic DNA methylation changes. To identify permanent MDMA-induced pathogenetic changes, mice received daily 10- or 35-day MDMA, or daily 10-day MDMA followed by 25-day saline washout (10 + 25 days). MDMA treatment caused differential gene expression (p < .05, fold change >1.5) in 752 genes following 10 days, 558 genes following 35 days, and 113 genes following 10-day MDMA + 25-day saline washout. Changes in MAPK and circadian rhythm gene expression were identified as early as 10 days. After 35 days, circadian rhythm genes (Per3, CLOCK, ARNTL, and NPAS2) persisted to be differentially expressed. MDMA caused DNA hypermethylation and hypomethylation that was independent of gene expression; hypermethylation of genes was found to be 71% at 10 days, 68% at 35 days, and 91% at 10 + 25 days washout. Differential gene expression paralleled DNA methylation in 22% of genes at 10-day treatment, 17% at 35 days, and 48% at 10 + 25 days washout. We show here that MDMA induced cardiac epigenetic changes in DNA methylation where hypermethylation predominated. Moreover, MDMA induced gene expression of key elements of circadian rhythm regulatory genes. This suggests a fundamental organism-level event to explain some of the etiologies of MDMA dysfunction in the heart.
