ABSTRACT

El objetivo fue identificar los factores asociados al éxito académico de los estudiantes de medicina distinguidos con diploma de honor por la Universidad de Buenos Aires. En 2011 se aplicó un cuestionario a 142 graduados con esta distinción en el 2006 que incluyó 59 preguntas sobre aspectos sociodemográficos, condiciones de vida e integración social, motivación para el estudio, capacidad de aprendizaje y estado de salud durante la carrera. En comparación con los demás alumnos, los exitosos habitaban más frecuentemente en la ciudad, provenían de escuelas medias privadas o universitarias, tenían menor necesidad de trabajar para financiarse, casi todos eran solteros y sin hijos, una proporción mayor vivía lejos de su familia, tenían más progenitores profesionales y eran financiados por ellos; nunca consideraron la salida laboral para elegir la carrera, para ellos era importante alcanzar el éxito y éste dependía principalmente del esfuerzo propio; solían manejar la ansiedad, eran sociables aunque independientes y preferían la experiencia concreta a la conceptualización abstracta para adquirir información. Con el actual sistema de ingreso, estos resultados sirven para cuantificar los mecanismos latentes de autoselección durante la carrera o en un régimen restrictivo, para seleccionar los candidatos a alcanzar el éxito académico. El análisis de los factores demográficos indica algún grado de inequidad para los estudiantes menos favorecidos socialmente. Quizás, un sistema de ingreso basado solo en las capacidades intelectuales, ayudaría a individualizar y apoyar a los mejores candidatos, independientemente de su contexto social.


The aim of this study was to identify common factors relating to the academic success of medical students who were distinguished with honors at the Buenos Aires University. In 2011, 142 graduates were surveyed; the questionnaire included 59 questions on their sociodemographic environment, living conditions and social integration, motivation to study, learning capacity and health quality during their career. Compared to other students, these distinguished students more often lived in the city, far from their families; had been educated at private or universitary high schools, their economic needs were financed by their parents, who were on the whole professionals. Most of them were single and childless. The possibility of future employment oportunities (work) did not influence their choice of a medical career, academic success was important to them and they believed that success depended largely on personal effort; they knew how to handle anxiety, were sociable but independent and preferred solid experience to abstract conceptuality in order to obtain information. Our conclusion, within the current system of candidate selection, these results serve to calculate the covert self-selection mechanisms during the career, or in a more restrictive regime, to select those likely to reach academic success due to their privileged ambience. The analysis of demographic factors indicates some degree of inequality for socially disadvantaged students. Perhaps, a selection system based only on intellectual abilities would help identify and support the best candidates regardless of their social context.

ABSTRACT

El objetivo fue explorar la utilidad del EuroSCORE logístico para estratificar las curvas de supervivencia alejada en una muestra de pacientes sometidos a cirugía cardíaca. Se analizaron los resultados a 8 años de 390 pacientes sometidos a cirugía cardíaca entre 2003-2004, de acuerdo al puntaje inicial del EuroSCORE logístico, divididos en tres grupos de riesgo: < 5%, 5-14.9% y ≥15%. La supervivencia por Kaplan-Meier a 8 años de la cirugía coronaria dividida por el EuroSCORE fue 83.5% para un riesgo inicial < 5%, 65.2% para un riesgo inicial entre 5 y 14.9% y 40.0% para un riesgo inicial ≥15% (p = 0.000); mientras que de la cirugía valvular o combinada fue 86.1%, 60.0% y 18.2% respectivamente (p = 0.0000). Para el total de pacientes, el área ROC fue 0.759 (p = 0.000), para un EuroSCORE <5% fue 0.689 (p = 0.002), entre 5 y 14.9% fue 0.544 (p = 0.499) y para ≥15% fue 0.725 (p = 0.067). En conclusión, el EuroSCORE logístico permitió estratificar adecuadamente las curvas de supervivencia alejada en una muestra de pacientes sometidos a cirugía cardíaca, tanto en la cirugía coronaria como en la valvular o combinada. La estratificación de los resultados a largo plazo separados por riesgo constituye una forma razonable de presentar el pronóstico.


The objective was to explore the usefulness of the logistic EuroSCORE to stratify the long-term survival curves in a sample of patients undergoing cardiac surgery. The 8-year survival of 390 patients undergoing cardiac surgery between 2003 and 2004 was analyzed, according to the basal value of the EuroSCORE, patients were classified into three risk groups: < 5%, 5-14.9% and ≥15%. Eight-years Kaplan-Meier's survival after coronary artery bypass grafting divided by the basal EuroSCORE was 83.5% for a basal risk < 5%, 65.2% for a basal risk 5 to 14.9% and 40.0% for a basal risk ≥15% (p = 0.000); whereas for valve or combined surgery it was 86.1%, 60.0% and 18.2% respectively (p = 0.0000). For all patients, ROC area was 0.759 (p=0.000), for a EuroSCORE <5% it was 0.689 (p = 0.002), between 5 and 14.9% it was 0.544 (p = 0.499) and for ≥15% it was 0.725 (p = 0.067). In conclusion, the logistic EuroSCORE allowed properly stratify the long-term survival curves in a sample of patients undergoing cardiac surgery, both the coronary and valve or combined surgery. Long-term results stratified by risk are a reasonable way to present late postoperative survival.
