OBJECTIVES: To evaluate the knowledge about contraceptives, its uses, efficacy, and adverse effects in an adolescent’s population of a public high school. MATERIALS AND METHODS: Descriptive retrospective study based on national and regional literature. RESULTS: Voluntary donations increased to 19.0%, screening of blood spread with the seven tests at 100% of the units collected nationwide, avoiding transfusion HIV infection, hepatitis B and C, HTLV-1 and 2, syphilis and Chagas disease. CONCLUSIONS: Implementation of Hemotherapy and Blood Banks National Program (PRONAHEBAS) had a positive impact by increasing transfusion safety by expanding testing and voluntary donation.

Objectives. Classifying blood lead levels and identifying the factors associated with elevated blood lead levels in children living in a district of Callao. Materials and methods. Transversal descriptive study. The study population was composed of children of both sexes from 1 to 13 years old; the data collection was conducted between March and April 2017. Results. The 310 children studied presented an average blood lead level of 8.59 μg/dL, while the median (P50) blood lead level was higher in males (p=0.008). Blood lead levels in 18.1% of the study population (n=56) were <5 μg/dL; in 54.5% (n=169) levels ranged between 5 and 10 μg/dL, whereas 27.4% (n=85) reported blood lead levels of ≥10 μg/dL furthermore, blood lead levels were significantly different between genders (p=0.007), while significantly more children under 10 years of age (p=0.008) and whose parents did not receive a...

Introducción: Los virus linfotrópicos humanos (HTLV), particularmente el HTLV-1 están asociados a leucemia/linfoma de células T del adulto (ATLL) y mielopatía/paraparesia espástica tropical (HAM/TSP). En América del Sur el Perú es considerado área endémica. Objetivos: Determinar la seroprevalencia de infección por HTLV1-2 en donantes de sangre de un hospital nacional de Lima. Métodos: Estudio descriptivo basado en una fuente secundaria obtenida del banco de sangre del Hospital Nacional Dos de Mayo. La población estuvo conformada por donantes de sangre postulantes de ambos géneros en el periodo 2012 a 2015. Los criterios de inclusión fueron: contar con datos personales, edad, sexo, grupo sanguíneo y los resultados del examen de pesquisa para HTLV-1 y HTLV-2. De 28249 sujetos admitidos, 28084 cumplieron con los criterios del estudio. Resultados: La edad media de los partici...

The aim of the study was to determine the frequency of infection markers for hepatitis B and hepatitis C and to identify associated factors in blood donors. The study was carried out using data obtained from blood donor medical records collected in a public hospital in Lima. Of 28,263 individuals analyzed between 2012 and 2015, 0.6% (n=156) were reactive for HBsAg; 5.2% (n=1,465), for anti-HBc; and 0.8% (n=232), for anti-HVC. Positive results for HBsAg (p=0.319) and anti-HVC (p=0.037) were more common in voluntary donors. For HBsAg and anti-HBc, positive results were more common in individuals aged 50 years or older. The number of voluntary donors was higher among individuals younger than 20 years (p<0.001). The study indicates that reactivity to hepatitis infection markers is associated with voluntary donation and the age group of blood donors.

Introduction: Global mortality due to noncommunicable diseases is high and increasing. In Peru it represents 66% of the deaths. Objective: The objectives of this study were to determine the frequency of obesity and overweight, and to evaluate cardiovascular and metabolic risk. Materials and methods: A cross-sectional descriptive study developed between July and November of 2016, the participants were faculty members of a private university located in the northern area of Lima. To determine the overweight and obesity was used the body mass index; cardiovascular and metabolic risks were assessed with the abdominal perimeter; and the risk of diabetes mellitus was determined using the FINDRISC questionnaire. Results: Of the 164 participating teachers, 51.8% (n = 85) were less than 45 years old, 73.2% (n = 120) were males, 3% (n = 5) had a history of hypertension and 5.5% (n = 9) diabetes mel...

Objectives. To determine and correlate the bone mineral density (BMD) and the biochemical markers of bone metabolism in adults 30 to 40 years old from Lima, Perú, in year 2018. Methods. A total of 84 women and 53 men, 30 to 40 years old from Lima, Perú, were submmited to a descriptive, transversal study. They did not have symptoms nor treatment for bone metabolic diseases. Information about their present health state, personal and familiar physiological and pathological history and physical examinatión were registered.
