Objective: Cardiovascular diseases are the most important causes of mortality in patients with end-stage renal disease. However, viral infections (hepatitis B and C) have acquired great importance for patients undergoing hemodialysis, because they affect patients' survival and increase morbidity and mortality. This study aimed at assessing the influence of hepatitis C on the mortality of patients undergoing hemodialysis. Methods: This is a non-concurrent cohort study during a period of ten years. Results: Each cohort comprised 74 patients. Hepatitis C did not increase the risk of death, and the survival of infected patients was better than that of patients without hepatitis C. The one-year and five-year survivals of non-infected patients were 93.9% and 52.3%, respectively, while those of noninfected patients were 95.5% and 73.1%, respectively (Cox-Mantel log-rank, p = 0.02). Conclusion: No increase in mortality risk was observed. Hepatitis C did not correlate with an increase in mortality in patients with end-stage renal disease undergoing hemodialysis.
“Dale un pez a un hombre hambriento y lo alimentarás durante un día, enséñale a pescar y lo alimentarás para toda su vida” (proverbio chino). Esta frase encaja perfectamente en uno de los modelos de aprendizaje más utilizados en los distintos niveles de la formación médica: el autoaprendizaje. Es principalmente en los estudios de posgrado donde se convierte en la principal estrategia didáctica para lograr los objetivos de aprendizaje. Se ha mencionado que no resolver una interrogante de nuestros estudiantes es invitarlos a la revisión y a la reflexión; y, por consecuencia, al aprendizaje. Pues parece que lo que realmente hacemos es lanzar a nuestros estudiantes hambrientos al mar a ver si pescan algo, y, además del riesgo de no pescar nada, existe el riesgo de que se ahoguen en el intento. Entonces, ¿qué hacer? Es una interrogante que trataremos de responder en este artículo.
