[Factors related to the scientific production of gastroenterologists in Lima-Peru]. / Factores relacionados con la produccion cientifica de los medicos gastroenterologos en Lima-Peru.

INTRODUCTION: The biomedical investigation in Peru is limited; among the implicated factors we have the reduced per-capita expense in investigation, the disperse efforts and the low communication between the investigations and the social productive activities. OBJECTIVES: To determinate the personal, professional and academic factors related with the scientific production of the medical gastroenterologists that work in province Lima. MATERIAL AND METHODS: Co-relational, observational, comparative, transversal and retrospective studies that had happened in between march 2007 and april 2008. Was elaborated a survey containing the variables of the investigation which was applied autoadministered to the gastroenterologists. Using bivaried and multivaried, were identified factors related with the scientific production of the gastroenterologist. RESULTS: The bivaried analysis has found, as related factors with the scientific production: Teaching, type of bibliographic research, degree of comprehension of the scientific article, facilities for the investigation at the job, subscription at the scientific magazine, to belong to the scientific society and the number of employments. The multivaried analysis found the previous factors but teaching and subscription to the scientific magazine, related with the scientific production. CONCLUSIONS: Those gastroenterologists that, despite being in contact with factors that impede the development of the investigation, had overcome the local negative influence and emerge, deserve consideration, because is on them were we can recognize factors that favor the investigation labor.

Factores relacionados con la producción científica de los médicos gastroenterólogos en Lima-Perú / Factors related to the scientific production of gastroenterologists in Lima-Peru

INTRODUCCIÓN: La investigación biomédica en el Perú es limitada. Entre los factores implicados en este problema tenemos el reducido gasto per-cápita en investigación, los esfuerzos dispersos y la escasa comunicación entre la investigación y las actividades sociales y productivas. OBJETIVOS: Determinar los factores personales, laborales y académicos relacionados conla producción científica de los médicos gastroenterólogos que laboran en Lima provincia. MATERIAL Y MÉTODOS: Estudio correlacional, observacional, comparativo, transversal y retrospectivo que se realizó entre marzo del 2007 y abril del 2008. Se elaboró una encuesta conteniendo las variables de investigación, la cual se aplicó autoadministada a los gastroenterólogos. Usando análisis bivariado y multivariado, se identificaron factores relacionados con la producción científica de los gastroenterólogos. RESULTADOS: El análisis bivariado encontró como factores relacionado con la producción científica: docencia, tipo de búsqueda bibliográfica, grado de comprensión de artículo científico, facilidades para la investigación en el trabajo, suscripción a revista científica, pertenecer a sociedad científica y el número de empleos. El análisis multivariado encontró a los factores anteriores menos docencia y suscripción a revista científica, como relacionados con la producción científica. CONCLUSIONES: Son factores positivos para una mayor producción científica entre los gastroenterólogos: hacer actividad docente, consultar publicaciones científicas de la especialidad por internet, estar suscritos a publicaciones científicas, comprender los contenidos de dichas publicaciones, tener facilidades para realizar investigación y finalmente tener más de dos trabajos. Hay que estudiar estos aspectos en profundidad para ver como estimular la producción científica e investigación.

[Analysis of a lactose tolerance test]. / Análisis de la prueba de tolerancia a la lactosa.

OBJECTIVE: The present study analyzes the Lactose Tolerance Test in order to propose a reduction in the length of it. DESIGN: Cross-sectional, descriptive study. METHODS: Glycemia curves of patients considered tolerant and intolerant were compared. Results were analyzed for 56 patients. A cost minimization analysis was performed. RESULTS: Six patients had a normal curve of tolerance and the other 50 had flat curves. Both groups had similar basal levels of glycemia 93.3 and 90.3 (p=0.1). Glycemia levels measured at 30 minutes were 122 and 86.0 (p= 0.003) and at 60 minutes 108.3 and 87.5 (p=0.02), both groups being statistically different. Values at 120 minutes were not statically different between both groups (p=0.4) and not different from basal levels. CONCLUSIONS: Diagnosis of lactose intolerance could be made using a shorter test, without considering the 120-minute figure. A 25% reduction in user s cost could be attained using the modified method as compared with the standard test.
