Relationship between adipokines and androgens in children and young adults with congenital adrenal hyperplasia.

Introduction: Children and young adults with congenital adrenal hyperplasia (CAH) are at increased risk of obesity and insulin resistance. There is evidence that children with CAH have increased visceral adiposity, which has been linked to metabolic syndrome and cardiovascular disease (CVD). The adipokine adiponectin has been shown to correlate with reduced metabolic risk, whereas the adipokines visfatin and leptin have been linked to visceral fat and adipocyte inflammation and can serve as biomarkers of increased metabolic risk. Few studies to date have characterized adipokine levels in children and young adults with congenital adrenal hyperplasia. We sought to investigate the relationship between adiponectin, leptin and visfatin levels to metabolic risk factors and androgen levels in children and young adults with CAH. Methods: Fasting blood was obtained for visfatin, leptin, adiponectin, glucose, insulin, CRP, lipid panel, total cholesterol (TC), triglycerides (TG) and HbA1c, as well as standard laboratory tests to assess adrenal control, from children with CAH due to 21-hydroxylase deficiency. HOMA-IR was calculated based on fasting glucose and insulin. Anthropomorphic measurements of BMI and waist-to-hip ratio were also obtained. Results: Adiponectin and androstenedione were inversely correlated (R = -0.57, p =0.016). There was a positive correlation between leptin and BMI percentile (R = 0.63, p <0.001) as well as leptin and HOMA-IR (R = 0.63, p <0.01). Glucocorticoid dose had a positive correlation with HOMA-IR (R=0.56, p = 0.021). Visfatin was inversely correlated with HDL cholesterol (R = -0.54, p = 0.026) and total cholesterol (R = -0.49, p <0.05). Overweight children and young adults had a significantly higher leptin (p = 0.02) and HOMA-IR (p=0.001) than non-overweight children and young adults. Conclusion: The inverse relationship between adiponectin and androstenedione suggests that better CAH control can reduce the risk of insulin resistance and metabolic syndrome. However, a high glucocorticoid dose appears to increase the risk of insulin resistance, underscoring the delicate balance required when treating CAH.

Virtual Clinical Shadowing for Pre-Clinical Medical Students in an Emergency Medicine-Based Leadership Course.

Purpose: The COVID-19 pandemic limited pre-clinical medical students from participating in traditional clinical in-person shadowing. Rather than eliminating clinical shadowing from an established leadership course, we describe the experience of six pre-clinical medical students shadowing physician preceptors remotely through virtual platforms. Methods: Six pre-clinical medical students enrolled in 2020's Weill Cornell Medicine's Healthcare Leadership and Management Scholars Program were prepared with training materials for on-camera patient care. Students shadowed emergency medicine (EM) physicians providing clinical care in one of our New York Presbyterian emergency departments (EDs) and through telemedicine. Pre- and postsurveys were provided to these students. Results: From three different U.S. time zones, students were safely able to shadow EM physicians. The educational fidelity was maintained in physician-student relationships, but revealed opportunities for improvement in students' clinical learning, in ED clinical care, and in telemedicine visits. Conclusions: Virtual clinical shadowing is a viable option for pre-clinical students, when in-person options are not available. With logistical adjustments, this medium may be a long-term educational option especially for telemedicine.
