Conocimientos, prácticas y actitudes del manejo programático de la tuberculosis en estudiantes de medicina de Colombia / Knowledge, practices and attitudes of the programmatic management of tuberculosis among Colombian medical students

Introducción: La tuberculosis es una enfermedad infecciosa con alta carga de la enfermedad en Colombia, por lo que se espera que la educación médica sea estándar en todas las regiones y los estudiantes de medicina tengan competencias en el manejo operativo de la tuberculosis. Este estudio evaluó los conocimientos, actitudes y prácticas en tuberculosis en estudiantes de medicina de Colombia y los factores relacionados. Métodos: Cuestionario de evaluación de conocimientos, actitudes y prácticas en tuberculosis en estudiantes de medicina en Colombia, que cursaban semestre clínico y se encontraban inscritos en la reunión anual 2020 de la Asociación de Sociedades Científicas de Estudiantes de Medicina de Colombia (ASCEMCOL) para establecer el nivel de conocimientos en tuberculosis. Resultados: Se evidenció que los estudiantes de regiones con mayor carga de la enfermedad como el Eje Cafetero presenta puntajes más altos de forma diferencial a las otras regiones. Por otra parte, se observó que la experiencia propia del estudiante en el tamizaje para tuberculosis (prueba cutánea de la tuberculina PPD - Mantoux) y la experiencia en la atención de pacientes con tuberculosis en el entorno clínico están relacionadas a los conocimientos del manejo programático de la tuberculosis. Conclusión: El estudio demuestra bajo nivel de conocimientos, actitudes y prácticas del manejo programático de la tuberculosis en los estudiantes de medicina que cursaban semestres clínicos en Colombia.

Background: The tuberculosis is an infectious disease with high disease burden in Colombia, so medical education is expected to be standard in all regions and medical students have competencies in the operative management of tuberculosis. This study evaluated the knowledge, attitudes, and practices in tuberculosis in medical students in Colombia and related factors. Methods: Questionnaire for the evaluation of knowledge, attitudes, and practices in tuberculosis in medical students in Colombia, who were in clinical semesters and were registered at the 2020 annual meeting of the Asociación de Sociedades Científicas de Estudiantes de Medicina de Colombia (ASCEMCOL) to establish the level of knowledge in tuberculosis. Result: The study found that students from regions with a higher burden of disease, such as the Eje Cafetero had higher scores that those from other regions. On the other hand, it was observed that the student´s own experience in tuberculosis screening (tuberculin skin test PPD – Mantoux) and the clinical experience in care patients with tuberculosis are related to the knowledge of the programmatic management of tuberculosis. Conclusions: The study shows a low level of knowledge, attitudes, and practices of programmatic management of tuberculosis in medical students in clinical semester in Colombia. (AU)

Pattern Electroretinogram Parameters Are Associated with Optic Nerve Morphology in Preperimetric Glaucoma after Adjusting for Disc Area.

PURPOSE: We examined the relationships between pattern electroretinogram and optical coherence tomography derived optic nerve head measurements, after controlling for disc area. METHODS: Thirty-two eyes from 20 subjects with preperimetric glaucoma underwent pattern electroretinogram and optical coherence tomography. Pattern electroretinogram parameters (Magnitude, MagnitudeD, and MagnitudeD/Magnitude ratio) and optic nerve head measurements (rim area, average cup to disc ratio, vertical cup to disc ratio, cup volume, retinal nerve fiber layer thickness sectors, and Bruch's membrane opening-minimum rim width thickness sectors) were analyzed after controlling for disc area. RESULTS: Magnitude and MagnitudeD were significantly associated with rim area (r ≥ 0.503, p ≤ 0.004). All pattern electroretinogram parameters significantly correlated with Bruch's membrane opening-minimum rim width sectors-temporal superior and nasal inferior (r = 0.400, p=0.039)-and retinal nerve fiber layer sectors-superior, nasal superior, and inferior (r ≥ 0.428, p ≤ 0.026). Magnitude and MagnitudeD explained an additional 26.8% and 25.2% of variance in rim area (B = 0.174 (95% CI: 0.065, 0.283), p=0.003, and B = 0.160 (95% CI: 0.056, 0.265), p=0.004), respectively. MagnitudeD and MagnitudeD/Magnitude ratio explained an additional 13.4% and 12.8% of the variance in Bruch's membrane opening-minimum rim width global (B = 38.921 [95% CI: 3.872, 73.970], p=0.031, and B = 129.024 (95% CI: 9.589, 248.460), p=0.035), respectively. All Bruch's membrane opening-minimum rim width sectors and retinal nerve fiber layer sectors (nasal superior, nasal inferior, and inferior) were significantly correlated with rim area (r ≥ 0.389, p ≤ 0.045). CONCLUSION: PERG abnormalities can predict rim area loss in preperimetric glaucoma after controlling for disc area. We recommend controlling for disc area to increase diagnostic accuracy in early glaucoma.
