RESUMO

OBJECTIVE: Since 2002, the Klingenstein Third Generation Foundation (KTGF) has supported a network of medical student mentorship programs (MSMPs) across the USA with the explicit aim of enhancing interest in, and eventual recruitment into the field of child and adolescent psychiatry (CAP). The authors conducted a multisite, retrospective cohort analysis to examine the impact of the program on career selection, as reflected by graduation match rates into psychiatry or pediatrics. METHODS: The authors collected graduating match information (2008-2019) from fourteen participating medical schools (Exposed) and thirteen non-participating schools (Control). Control schools were selected based on region, comparable student body and faculty size, national standing, and rank in NIH funding. Match rates into psychiatry and pediatrics were compared between Exposed and Control groups. RESULTS: Exposed schools had significantly higher match rates into psychiatry as compared to unexposed schools (6.1% and 4.8%, respectively; OR [95%CI] = 1.29 [1.18, 1.40]; X2 = 32.036, p < 0.001). In contrast, during the same time period, exposed schools had significantly lower match rates into pediatrics than unexposed ones (11.6 and 10.5%, respectively; OR [95%CI] = 0.89 (0.83, 0.95); X2 = 12.127, p < 0.001). These findings persisted even after adjustment for secular trends in match rates. CONCLUSIONS: Seventeen years after its inception, the KTGF medical student mentorship program network has had a positive impact on match rates into general psychiatry. Future studies will address whether these results translate to trainees' eventual selection of careers in CAP.

RESUMO

Glucocorticoids (GCs) and dehydroepiandrosterone (DHEA) are steroids secreted by the adrenal glands into circulation to effect distant target tissues and coordinate physiological processes. This classic systemic view of steroids has been challenged by evidence that other tissues can independently synthesize their own steroids. Little is known however regarding circumstances that can promote this extra-adrenal steroidogenesis. Here we tested if fasting can induce tissues to increase GC and DHEA synthesis in the brown anole lizard Anolis sagrei. Lizards fasted for eight days lost body mass and increased fatty acid oxidation. Fasting also increased plasma concentrations of DHEA and corticosterone, but not cortisol. Corticosterone concentration within the adrenals, heart, intestines, lungs and liver exceeded that in plasma, with the latter two increasing with fasting. Levels of DHEA in the adrenals and heart were higher than in plasma, but no significant effect of fasting was observed, expect for a noticeable increase in intestinal DHEA. Two steroidogenic genes, the steroidogenic acute regulatory (Star) protein and Cyp17a1, a cytochrome P450 enzyme, were expressed in several tissues including the liver, lungs and intestines, which were increased with fasting. Continued research should aim to test for expression of additional enzymes further along the steroidogenic pathway. Nonetheless these data document potential extra-adrenal steroidogenesis as a possible mechanism for coping with energy shortages, although much work remains to be done to determine the specific roles of locally synthesized steroids in each tissue.
