Correlación entre niveles séricos de PCR ultrasensible y riesgo cardiovascular en una cohorte de mujeres adultas

La PCR es el marcador de inflamación vascular más estudiado y validado hasta la fecha. Los niveles de PCR ultrasensible pueden predecir el riesgo de enfermedad cardiovascular. En el programa “salud integral para la mujer” de la fundación cardio-infantil se realizan estratificaciones de riesgo cardiovascular a mujeres adultas. Se midieron los niveles de PCR en este grupo de pacientes entre Octubre del 2007 y Mayo del 2009 y se evaluó la correlación entre la estratificación del riesgo cardiovascular por escala de Framingham y niveles de PCR en esta población. Objetivo: establecer el grado de correlación entre los niveles de PCR ultrasensible y el grado de riesgo cardiovascular y otros factores de riesgo cardiovascular. Resultados: Edad promedio 48 años (18 a 98 años). 62 pacientes hipertensas (40,7%). 19 pacientes con cifras alteradas de glicemia en ayunas (12%). Hay un 83% de la población estudiada con dislipidemia (127 pacientes). 78 pacientes con sobrepeso u obesidad. El 87% de la población tiene al menos un factor de riesgo presente. Discusión y resultados: En la población estudiada existe una alta prevalencia de factores de riesgo cardiovasculares, dentro de los cuales predomina los trastornos del metabolismo de los lípidos. Sin embargo no hay correlación entre los niveles de PCR ultrasensible y el riesgo cardiovascular según la escala de Framingham. En la literatura médica publicada sobre PCR ultrasensible y su relación con el riesgo cardiovascular los resultados son muy divergentes con los encontrados en este estudio.

Medical Student’s Use of Time During Clinical Clerkships and the Credits Based System

Introduction: Comprehensive undergraduate education in clinical sciences is grounded on activities developed during clerkships. To implement the credits system we must know how these experiences take place. Objectives: to describe how students spend time in clerkships, how they assess the educative value of activities and the enjoyment it provides. Method: We distributed a form to a random clustered sample of a 100 students coursing clinical sciences, designed to record the time spent, and to assess the educative value and the grade of enjoyment of the activities in clerkship during a week. Data were registered and analyzed on Excel® 98 and SPSS. Results: mean time spent by students in clerkship activities on a day were 10.8 hours. Of those, 7.3 hours (69%) were spent in formal education activities. Patient care activities with teachers occupied the major proportion of time (15.4%). Of the teaching and learning activities in a week, 28 hours (56%) were spent in patient care activities and 22.4 hours (44.5%) were used in independent academic work. The time spent in teaching and learning activities correspond to 19 credits of a semester of 18 weeks. The activities assessed as having the major educational value were homework activities (4.6) and formal education activities (4.5). The graded as most enjoyable were extracurricular activities, formal educational activities and independent academic work. Conclusion: our students spend more time in activities with patients than the reported in literature. The attending workload of our students is greater than the one reported in similar studies.
