Contiene una visión integral de la teoría y del proceso educativo. En sus páginas se aprecia la concisión de estilo y argumentación, y la búsqueda de situaciones concretas en las que se contrastan las afirmaciones. Es un valioso documento de estudio para estudiantes y profesionales que enriquece, al igual que las obras anteriores del autor, el universo teórico de la educación en el Perú.

Introduction. Giardiasis is caused by an intestinal protozoan, Giardia lamblia. Despite its high prevalence and geographical transmission variability, there is no risk stratification tool available to prioritize interventions. Objective. To estimate the prevalence of G. lamblia in Peruvian preschoolers and schoolchildren by ecoregion from 1990 to 2018. Methods. Based on a previous meta-analysis, we conducted a G. lamblia prevalence sub-analysis by ecoregions from data of 26 studies in Peruvian preschoolers and school-aged children between 1990 and 2018. The data was extracted by district, a classification by ecoregions was made through Google Earth. Heterogeneity was analyzed using Cochrane Q test and publication bias applying the Egger method with StatsDirect version 3.2.7. The absolute risk method was performed to stratify the prevalence at district level, and 4 strata were defined bas...

Introducción. La giardiasis es ocasionada por el protozoario intestinal Giardia lamblia, su transmisión tiene variabilidad geográfica y a pesar de ser muy frecuente, no existe una herramienta de estratificación de riesgo para priorizar las intervenciones. Objetivo. Estimar la prevalencia de G. Lamblia en preescolares y escolares peruanos por ecorregiones entre 1990 a 2018. Métodos. A partir de un metaanálisis previo, se realizó un subanálisis por ecorregiones de la prevalencia de G. lamblia en 26 estudios en preescolares y escolares peruanos entre 1990 a 2018. Se extrajeron los datos por distrito y utilizando Google Earth fueron clasificados en ecorregiones. La heterogeneidad fue analizada mediante la prueba de Q de Cochrane y el sesgo de publicación mediante el método de Egger con StatsDirect versión 3.2.7. Se utilizó el método de riesgo absoluto para estratificar la preval...

The study aimed to determine the prevalence and distribution of Giardia lamblia in the Peruvian population between 1990 and 2018. A systematic review and meta-analysis of cross-sectional studies was carried out. It was included original studies on the prevalence of G. lamblia, intestinal parasitism or cohort studies that included prevalence data, and diagnosed by parasitological examination, antigen detection, PCR or genetic analysis, published between 1990 and 2018 in Spanish, English, Portuguese or French and carried out in humans. Searches were performed in PubMed, Scopus, LILACS, SciELO, LIPECS, Google Scholar, and ALICIA. Analysis of heterogeneity was performed using Cochrane's Q test and publication bias using Egger's method with StatsDirect v. 3.2.7. The analysis included 33 sources that had information from 37 studies involving 10 109 individuals. The combined prevalence by the ...

Background: Breast cancer women have a tendency to develop psychiatric symptomatology, mainly depressive. A way to evaluate how the patient entails her disease is by quality of life. Objectives: To determine the prevalence of depressive symptoms and quality of life and their associations with time since diagnosis and the menopausal status. Design: Analytical, observational and transversal study. Setting: Arzobispo Loayza Hospital Oncology Service. Participants: Women with clinical and histological diagnosis of breast cancer and seeking chemotherapy. Interventions: The Beck depression inventory, the Mezzich and Cohen quality of life scale and a demographic questionnaire were used. The Fisher test, student’s T-test and lineal regression analysis were used. Main outcome measures: Depression symptoms, quality of life. Results: In 24 women studied the prevalence of depressive symptoms and l...
