Objetivo: Determinar el rendimiento diagnóstico de la tinción Ziehl-Neelsen y Auramina-Rodamina para tuberculosis pulmonar y extrapulmonar. Materiales y métodos: Se realizó un estudio transversal de prueba diagnóstica. Se utilizó una base de datos de muestras procesadas de pacientes con sospecha de tuberculosis pulmonar y extrapulmonar en un laboratorio privado de Perú entre el 2011 y 2022. Las pruebas índices fueron la tinción Ziehl-Neelsen y tinción Auramina-Rodamina. Las pruebas de referencia fueron Xpert MTB/RIF y Xpert Ultra. Se calculó las características operativas del receptor y área bajo la curva (AUC/ROC) para determinar el rendimiento diagnóstico de cada técnica de baciloscopia. Resultados: Analizamos 908 muestras procesadas por tinción Ziehl-Neelsen y 623 muestras por tinción Auramina-Rodamina siendo la mayoría de origen pulmonar. Al tomar como referencia al...

Objective: The aim of this study was to evaluate sociodemographic inequities related to the coverage and compliance of the two-dose measles vaccination among Peruvian children in 2023. Materials and methods: An analytical cross-sectional study was conducted using data from a Demographic and Health Survey. Mothers aged 15 to 49 with children aged 12 to 59 months were included. Sociodemographic and health characteristics of these mothers were evaluated for inequity analysis using the Concentration Index (CI). This analysis was used to evaluate inequity in vaccination for first and booster doses against measles, and it was complemented with the Erreygers Concentration Index (ECI) and its decomposition. Results: Sixteen thousand, five hundred and twenty-six Peruvian mothers with at least one child aged 12 to 59 months were evaluated. Vaccination coverage was 85.7% and 54.4% for the first and...

Objective: To examine the factors associated with Peruvian physicians' adherence to guidelines for managing mild COVID-19 cases. Methods: An analytical cross-sectional study was conducted, surveying certified Peruvian physicians from different regions. A simulated clinical case was used to evaluate their knowledge of the pharmacological management of mild COVID-19 and the potential adverse effects of prescribed medications. Adherence to guidelines was defined as prescribing only acetaminophen and/or non-steroidal anti-inflammatory drugs (NSAIDs) for the proposed mild COVID-19 case, in accordance with international recommendations. Factors associated with adherence were analyzed using prevalence ratios, calculated through Poisson regression with robust variance. Results: A total of 339 physicians participated, 85.0% of whom adhered to the recommended guideline. The most frequently prescri...
