A prevalência de mulheres grávidas infectadas pelo HIV no Brasil é cerca de 0,4%. Apesar da obrigatoriedade do registro desde 2006, os casos diagnosticados e notificados de gestantes soropositivas correspondem a 70% do total estimado. OBJETIVO: Avaliar a associação entre tipo de parto e evolução da gestação em relação às características sociodemográficas, clinico-laboratoriais e gestacionais/puerperais das gestantes com HIV.

The objective was to verify the possibility of the production of tuberous roots of sweet potatoes in an aeroponic systemin order to use these roots as seeds. The research was developed at the State University of Ponta Grossa (PR – Brazil). There were performed four attempts for the developing ofone aeroponic system in a greenhouse, involving experiments with structures and nutrient solutions for seven sweet potatoes genotypes.

Objective: to investigate the health profile of high school teenagers in a public school in a municipality in the interior of Minas Gerais. Methods: a cross-sectional, descriptive study with a quantitative approach was carried out, through a structured questionnaire with questions about sociodemographic data, lifestyle habits and search for the health service.

The Unified Health System (SUS) has the National Immunization Program (NIP), coordinated by the Ministry of Health, which has been consolidating itself as one of the most relevant public health interventions in the world. Created in 1973, in its 46-year trajectory, the PNI is characterized as an efficient public policy, increasingly impacting the profile of morbidity and mortality of the Brazilian population, adapting to changes in the political, epidemiological, and social fields.

This study aims to develop and evaluate the fruit nectar products in which the fruit juice and sugar were substituted with Aloe vera and stevia at various levels (treatment 1- 0%, treatment 2 - 25%, treatment 3 - 50%, treatment 4 - 75% and treatment 5 - 100%). Inulin was used for compensating the sucrose omission defects on TSS, bulkiness (mouth feel) properties of the nectar with numerous health benefits. The sensory evaluation of the treatments and their physico-chemical properties were studied and the well accepted products from sensory evaluation were selected for shelf-life studies.

Polymethylmethacrylate (PMMA) is a synthetic polymer produced in microspheres form, used in many biomedical areas. Objective: To determine the PMMA injections biocompatibility in striated muscle tissue of Wistar rats. Methods: In vivo biocompatibility and fibrous tissue healing were assessed by histopathological evaluation at 2, 4, 8, and 16 weeks after implantation in 3 groups of adult rats. Group 1, with 20 adult rats, was injected with 30% PMMA gel in the ventral muscle. Other two groups with 20 and 5 rats were studied as control subjects.

Chloroleucon dumosum (Benth) G.P. Lewis (Leguminosae-Mimosa (Currently Caesalpinioideae) - Ingeae) is a deciduous species, occurring in the Caatinga, in general fields and forests that form corridors along rivers and wetlands. It is usually called arapiraca, mahogany or white jurema. A large part of the projects aimed at the conservation and exploitation of native forest species depend on the formation of seedlings.

Biochar can be defined as vegetable biomass, which has undergone pyrolysis in a low oxygen environment. It can contribute to chemical, physical and biological improvements in the soil. Different biomasses can be used in the production of biochar. However, characterization studies are needed before its recommendation. The aim of this work was to test the temperatures: 300, 400 and 500 °C in Theobroma grandiflorum for biochar production and to characterize the samples, submitted to different temperatures, to verify which temperature presents the best chemical and physical properties.

Objetivo: Caracterizar a proteção respiratória dos profissionais lotados no expurgo durante a limpeza de Produtos para saúde (PPS)em tempos de Pandemia. Método: Estudo exploratório quantitativo, realizado, após autorização do Comitê de Ética e pesquisa nº parecer 4.539.579 e 42834621.0.0000.5198. Foi ministrado um treinamento sobreriscos e proteção respiratória para o coronavírus, seguido daaplicação de um questionário para avaliar o aprendizado. Resultados: Responderam à pesquisa 80% dos participantes(85/106), desses 27% (23/85) contraíram a doença entre janeiro e outubro de 2020.

Jamanxim National Forest is a protected area located in the Amazon biome, created in 2006, with the aim of mitigating the foreseen deforestation with BR-163 paving, a highway that crosses portions of the native Amazonforest. The highway paving was completed in a process that ran from 2016 to 2020. Since then, the region has emerged as the leader in deforestation rankings.
