PRODUCCIÓN CIENTíFICA PERUANA EN MEDICINA Y REDES DE COLAbORACIÓN, ANÁLISIS DEL SCIENCE CITATION INDEX 2000-2009

RESUMEN Objetivos. Describir la produccion cientifica peruana en revistas indizadas en el Institute for Scientific Information (ISI) y las caracteristicas de las redes de colaboracion institucional. Materiales y metodos. Se incluyo todos los articulos publicados en la base de datos ISI (coleccion Clinical Medicine) en el periodo 2000 a 2009 con al menos un autor con filiacion Peru. Se evaluo la tendencia de publicacion, procedencia del autor corresponsal, tipo de articulo, institucion, ciudad (solo para Peru) y pais. Se analizo las redes de colaboracion usando el programa Pajek ®. Resultados. Se encontro 1210 articulos, hubo un incremento de 61 en el 2000 a 200 en el 2009 (promedio 121 articulos/ ano). El autor corresponsal fue de una institucion peruana en el 30,4% de los casos. El promedio de autores por articulo fue de 8,3. Los articulos de investigacion representaron el 82,1% del total. Las revistas que concentraron la mayor cantidad de articulos fueron relacionados a enfermedades infecciosas. Los principales paises que colaboran con Peru son: Estados Unidos de Norteamerica (60,4%), Inglaterra (12,9%) y Brasil (8,0%). Lima concentro el 94,7% de las publicaciones y no se registro publicaciones procedentes de tres regiones (Huancavelica, Moquegua y Tacna). Solo dos universidades produjeron mas de un articulo/ano y cuatro instituciones produjeron mas de 10 articulos/ano. La Universidad Peruana Cayetano Heredia participo en el 45% de articulos siendo la institucion mas productiva y que concentra la mayor cantidad de colaboraciones con instituciones extranjeras. El Ministerio de Salud –con todas sus dependencias– participo con el 37,3% del total. Existe mayor nivel de colaboracion con instituciones extranjeras que entre nacionales. Conclusiones. La produccion cientifica peruana en medicina representada en la base ISI es escasa pero en crecimiento, esta concentrada en Lima y en pocas instituciones. Las instituciones peruanas mas productivas colaboran mas intensamente con instituciones extranjeras que con nacionales.

Avances y retos en la construcción del sistema nacional de investigación en salud en el Perú

The objective of this paper is to present the situational status of the National Health Research System of Peru (NHRS), the lessons learnt during the building process, the opportunities to improve it and the challenges. A description of the functions of the peruvian NHRS is done, in relation to governance, legal framework, research priorities, funding, creation and sustainability of resources and research production and utilization. It describes that in Peru we excert governance in research, we count with regulations, policy and research priorities, these last developed in the framework of a partipatory, inclusive process. The conclusion reached is that the challenges of the peruvian NHRS are to consolidate the governance and to develop the mechanisms to articulate the stakeholders involved in research, to improve the resources allocation for research and innovation, to ellaborate a plan for the development of human resources dedicated to research, to develop institutions and regional competences in order to perform research, and to link research in order to solve problems and make national research policies sustainable.

ALTA FRECUENCIA DE PLAGIO EN TESIS DE MEDICINA DE UNA UNIVERSIDAD PÚBLICA PERUANA

An observational study was conducted to describe the presence of plagiarism in medical thesis in 2008 performed at a public university in Peru. Search for plagiarism in 33 thesis introductions using a Google search algorithm, characterizes of the study type and we search in electronic form if the thesis mentor have published articles in scientific journals. We found evidence of plagiarism in 27/33 introductions, 37.3% (171/479) of all the paragraphs analyzed had some degree of plagiarism, literal plagiarism was the most frequent (20/27) and journals were the most common sources of plagiarism (19/27). The characteristics of the studies were observational (32/33), cross-sectional (30/33), descriptive (25/33) and retrospective (19/33). None of the authors had published in a scientific journal, and only nine of his tutors of them had at least one publication. No association was found between the characteristics of the thesis and the presence of plagiarism. In conclusion, we found a high frequency of plagiarism in theses analyzed. Is responsibility of medical schools take the necessary actions to detect and avoid plagiarism among their students.

Características de los cursos de investigación en escuelas de medicina del Perú

Aim: To evaluate the research courses’ characteristics and the scientific output of nits teachers within Peruvian medical schools. nMethods: A cross-sectional descriptive study was performed, using data from nthe medical schools existing in Peru in 2011. The research courses’ syllabi and its nteachers were evaluated. The number of courses, its teachers and the scientific noutput of them were assessed. Results: Schools had a median of 5.5 [range 2 to 18] credits of research courses, nand 1.75% [0.6 to 6.3] was the median of percentages of total credits. In 18/32 n(56%) schools existed at least one course requiring the student to present a final ninform, and only one school entailed the students to publish the courses’ products nin scientific journals. Furthermore, only five (16%) schools employed at least one ninstructor that had ever published at least one original article as the corresponding nauthor in a Scopus-indexed journal. nConclusion: Peruvian medical schools’ research courses do not include the npublication process as a targeted skill and its teachers have a poor scientific output.

Enseñando a publicar desde el pregrado

Teaching to publish since undergraduate en el ano 2001, cuando era estudiante de medicina y miembro de la sociedad cientifica (sOceM) de mi universidad en Lima, Peru, me encargaron una labor que no tenia la menor idea de lo que significaria para mi futuro, ser el director del v encuentro internacional de revistas cientificas de estudiantes de las ciencias de la salud (eircecs). digo esto, porque a pesar de estar involucrado en una sOceM, que traducia mi alto interes por la investigacion, no sabia que un estudiante de medicina podia publicar en una revista cientifica, y mucho menos, hacer una.

Factores asociados a apendicectomías negativas en una clínica privada de Lima-Perú

espanolObjetivo: Identificar la frecuencia de apendicectomias negativas (AN) y los factores asociados en una clinica privada de Lima. Metodos: Estudio retrospectivo de todas las apendicectomias realizadas entre los anos 2012 y 2013 en una clinica privada de Lima-Peru. Se reviso las historias clinicas de pacientes apendicectomizados que contaron con historia clinica de emergencia e informe quirurgico. Se excluyo a aquellos que no contaban con informe anatomopatologico del apendice. Se calculo los OR ajustados con un modelo de regresion logistica para identificar los factores asociados con AN. Resultados: Se realizaron 376 apendicectomias durante el periodo 2012-2013. Se excluyo 13 casos por no contar con registro de historia clinica. La poblacion femenina fue de 55.9%. La media de edad del paciente fue 33.4 ± 17.6 anos. En 28 de 363 pacientes (7.7%) se registro una AN. Se encontro que el dolor en flanco derecho (ORa: 5.4; IC95%: 1.4-20.8), Mc Burney negativo (ORa: 3.6; IC95%: 1.3-10.5), dolor en hipogastrio (ORa: 3.1; IC95%: 1.1-8.4), y no leucocitosis (ORa: 2.9; IC95%: 1.2-6.7) son factores asociados a una AN. Las patologias mas frecuentemente implicadas en el caso de una AN fueron las de causa ginecologica (53.6%) seguida de enfermedad diverticular complicada (14.3%). Conclusion: Los resultados obtenidos indican que la presencia de dolor en hipogastrio, dolor en flanco derecho, Mc Burney negativo y no leucocitosis son factores que se pueden tener en cuenta para prevenir apendicectomias negativas. EnglishObjective: Identify the frequency of negative appendectomy (NA) and associated factors associated in a private hospital in Lima. Methods: Retrospective study of all appendectomies performed between 2012 and 2013 at a private hospital of Lima-Peru. We reviewed the medical records of patients who underwent appendectomy and had a medical report of emergency. We excluded the ones without pathology reports. Adjusted ORs were calculated with a logistic regression model to identify factors associated with AN. Results: Three hundred seventy-six appendectomies were performed for suspected appendicitis 55.9% in women). The average patient age was 33.4 ± 17.6 years. We identified 28 AN cases of 363 patients (7.7%). We found that pain in right flank (aOR: 5.4; 95%CI: 1.4-20.8), negative Mc Burney (aOR: 3.6; 95%CI: 1.3- 10.5), pain in hypogastrium (aOR: 3.1; 95%CI: 1.1-8.4) and no leucocitosis (aOR: 2.9; 95%CI: 1.2-6.7) were associated factors to AN. Gynecologic conditions (53.6%) and complicated diverticular disease (14.3%) are the most common diagnosis in AN cases. Conclusion: The obtained results indicate that the presence of pain in the right flank, negative Mc Burney, pain in hypogastrium and no leukocytosis are factors that can be taken into account to prevent negative appendectomy.
