The treatment of arterial hypertension (AH) contributes to the reduction of morbidity and mortality. Gender differences are likely to play a role, as non-treatment is associated with clinical and sociodemographic aspects. The aim of this study was to investigate the factors associated with non-treatment of AH and gender differences in hypertensive individuals from the ELSA-Brasil cohort.

The human gut community has been studied in detail in infants and following dietary interventions in adults. However, the variability of the distribution of species and intra-species functions have been little studied, particularly beyond infancy. Here, we explore the ecology of communities in a large public dataset of human gut metagenomes, mostly corresponding to adults.

Glutathione transferases (GST) are detoxification enzymes that conjugate glutathione to a wide array of molecules. In the honey bee Apis mellifera, AmGSTD1 is the sole member of the delta class of GSTs, with expression in antennae. Here, we structurally and biochemically characterized AmGSTD1 to elucidate its function.

Background: Brazil leads the world in number of firearm deaths and ranks sixth by country in rate of firearm deaths per 100,000 people. This study aims to analyze trends in and burden of mortality by firearms, according to age and sex, for Brazil, and the association between these deaths and indicators of possession and carrying of weapons using data from the global burden of diseases, injuries, and risk factors study (GBD) 2017.

Methods: We used GBD 2017 estimates of mortality due to physical violence and self-harm from firearms for Brazil to analyze the association between deaths by firearms and explanatory variables.

We evaluated the influence of an Antarctic expedition, consisting of 26-day ship travel followed by 24-day camping in the Antarctic field during the summer season, on hormonal responses, autonomic cardiac control, and mood states in individuals that live in tropical regions. Data collection was carried out in 10 individuals on the 2nd, 16th, and 26th days aboard the ship (characterized by exposure to low-luminosity and temperature-controlled environments) and on the 4th, 11th, and 23rd days of camping in the Antarctic field (prolonged exposure to natural luminosity and cold environments). Morning samples of saliva (to determine testosterone and cortisol concentrations) and blood [to determine thyroid-stimulating hormone (TSH) and thyroxine (T4) concentrations] were obtained.

Objective: The prevalence of biotinidase deficiency and the frequency of biotinidase gene variants in Brazil are not documented. We aimed to determine the incidence of partial and profound biotinidase deficiency in the state of Minas Gerais, Brazil, and to calculate the frequency of biotinidase gene variants in the newborn screening program of Minas Gerais.

Methods: Neonates (1,168,385) were screened from May 2013 to June 2018.

Objective: To describe the profile of children and adolescents admitted for exogenous unintentional poisoning in the emergency room and analyze factors associated with subsequent in-hospital admissions.

Methods: This is a cross-sectional study based on hospital records of all subjects up to 19 years-old admitted in 2013 at a specialized toxicology service on a major public emergency hospital due to unintentional intoxication (as reported). Accidents with poisonous animals and insects were excluded.

Objective:: To describe the global burden of disease due to road traffic accidents in Brazil and federated units in 1990 and 2015.

Methods:: This is an analysis of secondary data from the 2015 Global Burden of Disease study estimates. The following estimates were used: standardized mortality rates and years of life lost by death or disability, potential years of life lost due to premature death, and years of unhealthy living conditions.

Objective:: To analyze mortality and years of life lost due to death or disability (disability-adjusted life years - DALYs) for interpersonal violence and self-harm, comparing 1990 and 2015, in Brazil and Federated Units, using estimates produced by the Global Burden of Disease 2015 (GBD 2015).

Methods:: Secondary data analysis of estimates from the GBD 2015, producing standardized death rates and years of life lost due to death or disability. The main source of death data was the Mortality Information System, submitted to correction of underreporting of deaths and redistribution of garbage codes.
