Introduction: Gliomas are primary tumors of the central nervous system. They are classifiedfrom grade I-IV, with high grade III and IV being the most frequent and with poor prognosis. Objective: To determine the prognostic factors of survival in patients with high-gradegliomas in a hospital in Lima, Peru. Methods: The medical records with high-grade gliomafrom 2010-2014 were retrospectively reviewed, ten variables were analyzed with Kaplan-Meier and Log Rank survival graphs and the Cox regression model. Results: Out of a total of278 patients with high-grade gliomas, 136 were men and 142 women. The analysis of Progression-Free Survival (SLP) had a range of 5.6-80.3 (median 22.7) and the analysis ofoverall survival (PS) had a range of 4-83.2 (median 26, 2 months. The overall survival for theIV grade tumor was 15.7 months (95% CI 14.2-17.1); the III degree was 38.4 months (95%CI 35.8-40.9)....

Introducción: El COVID 19 es una enfermedad infecciosa causada por el SARS-CoV-2 que ha afectado en gran escala al Perú. No están documentados los potenciales factores clínicos y/o epidemiológicos que están relacionados a la positividad de SARS-CoV-2 en población altoandina. Objetivo: Determinar los factores asociados a positividad de SARS-Cov-2 en personas que viven en Ancash. Material y métodos: Estudio transversal analítico. Se utilizaron los registros de pacientes atendidos por sospecha de COVID-19 en un hospital público de Huaraz en marzo-mayo 2020. Se estimaron razones de prevalencia (RP) con intervalos de confianza. En el análisis de regresión simple, se estimaron razones de prevalencia e intervalos de confianza al 95%, utilizando familia de distribución Poisson, función de enlace log y varianza robusta Resultados: De 903 pacientes, 13,7% pacientes resultaron positiv...

Background: COVID 19 is an infectious disease caused by SARS-CoV-2 that has affected Peru on a large scale. Potential clinical and/or epidemiological factors that are related to the positivity of SARS-CoV-2 in the high Andean population are not documented. Objective: To determine factors associated with positivity of SARS-CoV-2 in people living in Ancash. Material and methods: Analytical transversal study. We used the records of patients treated for suspected COVID-19 in a public hospital in Huaraz in March-May 2020. Prevalence ratios (PR) with confidence intervals were estimated. In simple regression analysis, prevalence ratios and 95% confidence intervals were estimated, using Poisson distribution family, log-link function and robust variance. Results: Out of 903 patients, 13.7% tested positive for SARS-CoV-2. In simple regression, male (RP=2.98), cough (RP=2.27), respiratory distress ...
