Background: Many medical schools require a student thesis before graduation. Publishing results in a peer-reviewed journal could be an indicator of scientific value and acceptability by the scientific community. The publication pattern of theses published by medical students in Peru is unknown. The aim of this study was to assess the characteristics and publication pattern of theses in biomedical-indexed journals conducted by medical students in a university with the highest research output in Peru. Methods: Data from registered theses between 2000 and 2003 were obtained from the university library. Publication of theses in biomedical journals was assessed in 2008 by a search strategy using PubMed, Google Scholar, LILACS, LIPECS and SciELO. Results: Four hundred and eighty-two medical theses were registered between 2000 and 2003; 85 (17.6%) were published in biomedical-indexed journals. Of the published theses, 28 (5.8%) were published in MEDLINE-indexed journals, 55 (11.4%) in SciELO-indexed journals, 61 (12.6%) in LILACS-indexed journals and 68 (14.1%) in LIPECS-indexed journals. Most of the published theses (80%) were in Spanish and published in Peruvian journals; and 17 theses (20%) were published in foreign journals (all of them indexed in MEDLINE). In addition, 37 (43.5%) belong primarily to internal medicine, and 24 (28.2%) belong primarily to infectious diseases. Medical students were first authors in 71 (83.5%) of the articles. Conclusion: In this study, most of the published theses were in Spanish, published in local journals and indexed in LIPECS. The percentage of published theses in biomedical journals at this university is comparable with others coming from developed countries.

Objetivos: Identificar factores asociados a la injuria renal aguda (IRA) en pacientes que acudieron a emergencia de un hospital general. Material y métodos: Estudio caso-control, se incluyeron 50 casos y 100 controles de pacientes incidentes a emergencia de un hospital III-B de Lima. Se analizó los datos mediante OR. Resultados: Los factores de riesgo encontrados fueron la condición de gravedad del paciente (OR=6,14), la presencia de un cuadro infeccioso como diagnóstico al ingreso, la existencia de sepsis y el estar en shock séptico (OR=2,85; 3,78 y 6,77 respectivamente). Las comorbilidades asociadas a la incidencia de IRA de la comunidad fueron: enfermedad respiratoria, alcohol y tabaco, neoplasia maligna y enfermedad neuropsiquiátrica (p=0,001). La edad, sexo y otras variables de filiación y situación socioeconómica no estuvieron relacionados. Conclusiones: Los factores asociados a IRA fueron la presencia de un cuadro infeccioso, su gravedad y la presencia de comorbilidades preexistentes.
