Effect of Recombinant Human Growth Hormone (rhGH) Use on Genetic Methylation Patterns and Their Relationship with Body Composition in Small-for-Gestational-Age (SGA) Newborns
Background: Low birth weight in newborns is of multifactorial origin (fetal, maternal, placental, and environmental factors), and in one-third of cases, the cause is of unknown origin, with high infant morbidity and mortality. The main treatment for regaining weight and height in children with low birth weight is the application of growth hormones. However, their role as a protective factor to prevent an increase in body composition and the development of metabolic diseases is still poorly understood. Methodology: A case–control study was conducted in a cohort of patients consulted at the CES Pediatric Endocrinology Clinic, Medellín, Colombia, between 2008 and 2018. We evaluated sociodemographic and clinical variables. Additionally, the identification of differential patterns of genomic methylation between cases (treated with growth hormone) and controls (without growth hormone treatment) was performed. The groups were compared using Fisher’s exact test for qualitative variables and Student’s t-test for the difference in means in independent samples. The correlation was evaluated with the Pearson coefficient. Results: Regarding clinical manifestations, body mass index (BMI) was higher in children who did not receive growth hormone treatment, higher doses of growth hormone treatment helped reduce body mass index (R: −0.21, and p = 0.067), and the use of growth hormone was related to a decrease in triglyceride blood concentrations (p = 0.06); these results tended towards significance. Regarding genome-wide methylation patterns, the following genes were found to be hypermethylated: MDGA1, HOXA5, LINC01168, ZFYVE19, ASAH1, MYH15, DNAJC17, PAMR1, MROCKI, CNDP2, CBY2, ZADH2, HOOK2, C9orf129, NXPH2, OSCP1, ZMIZ2, RUNX1, PTPRS, TEX26, EIF2A4K, MYO1F, C2orf69, and ZSCAN1. Meanwhile, the following genes were found hypomethylated: C10orf71-AS1, ZDHHC13, RPL17, EMC4, RPRD2, OBSCN-AS1, ZNF714, MUC4, SUGT1P4, TRIM38, C3, SPON1, NGF-AS1, CCSER2, P2RX2, LOC284379, GGTA1, NLRP5, OR51A4, HLA-H, and TTLL8. Conclusions: Using growth hormone as a treatment in SGA newborns helps regain weight and height. Additionally, it could be a protective factor against the increase in adolescent body composition.

Percepción de médicos internos sobre el aprendizaje en un servicio de urgencias
Introducción: pese a estar incluida en los currículos universitarios, la medicina de urgencias en Colombia enfrenta desafíos en la formación adecuada de profesionales; la enseñanza en este campo es limitada y poco investigada, afectando la atención de pacientes críticos. Se propone reorientar la educación médica para mejorar el aprendizaje en este ámbito. Objetivo: comprender el significado del aprendizaje en urgencias para los estudiantes de internado en la Clínica CES, describiendo cómo ellos perciben este entorno, las interacciones educativas que experimentan y cómo la práctica profesional en urgencias contribuye a su formación médica. Materiales y método: estudio cualitativo basado en el interaccionismo simbólico y la teoría fundamentada. Se realizaron entrevistas semiestructuradas a internos de medicina, con un análisis iterativo que permitió identificar categorías clave sobre su aprendizaje en urgencias. Resultados: se identificaron tres categorías clave: 1) el entorno de urgencias como espacio integral de aprendizaje; 2) la importancia de las interacciones educativas con docentes y personal de salud, y 3) el desarrollo del profesionalismo médico, ganando confianza y autonomía. Conclusiones: es esencial adaptar las interacciones educativas a las necesidades emocionales y cognitivas de los internos. El apoyo docente y el entorno de urgencias se reconocen como espacios significativos para el aprendizaje. La formación pedagógica de los docentes mejora la retroalimentación y el aprendizaje en este contexto.
