Clinical Profile of SARS-CoV-2 Infection: Mechanisms of the Cellular Immune Response and Immunogenetic Markers in Patients from Brazil.

Objectives: The aim of this study is to evaluate some mechanisms of the immune response of people infected with SARS-CoV-2 in both acute infection and early and late convalescence phases.

Methods: This is a cohort study of 70 cases of COVID-19, confirmed by RT-PCR, followed up to 60 days. Plasma Samples and clinical data were.

[Teenage pregnancy and prematurity in Brazil, 2011-2012].

The study aims to evaluate the association between teenage pregnancy and prematurity. The data are from the Birth in Brazil study, a national survey consisting of 23,894 postpartum women and their newborn infants. The information was obtained from interviews with the mothers during their postpartum hospital stay.

Advanced maternal age and factors associated with neonatal near miss in nulliparous and multiparous women.

The early neonatal period accounts for approximately half of the deaths of young children under one year of age, and the neonatal near miss can recognize factors causing this high number of deaths. Thus, the aim of this study is to determine whether advanced maternal age increases the chance of neonatal near miss, in addition is to identify which factors are associated with the neonatal near miss, stratified by parity. Data are from the 2011-2012 Birth in Brazil study, which used a national population-based sample of 15,092 newborns of women between 20-29 and 35 years of age or more (advanced maternal age).

Health facility structure and maternal characteristics related to essential newborn care in Brazil: a cross-sectional study.

Objectives: To assess the use of the WHO's Essential Newborn Care (ENC) programme items and to investigate how the non-use of such technologies associates with the mothers' characteristics and hospital structure.

Design: A cross-sectional observational health facility assessment.

Setting: This is a secondary analysis of the 'Birth in Brazil' study, a national population-based survey on postnatal women/newborn babies and of 266 publicly and privately funded health facilities (secondary and tertiary level of care).

The color of pain: racial iniquities in prenatal care and childbirth in Brazil.

Few studies on the influence of race/color on pregnancy and birthcare experiences have been carried out in Brazil. Additionally, none of the existing studies are of national scope. This study sought to evaluate inequities in prenatal and childbirth care according to race/color using propensity score matching.

gene polymorphism associated with clinical factors can predict drug-resistant tuberculosis.

Polymorphism in the gene encoding P-glycoprotein, a transmembrane drug efflux pump, contributes to drug resistance and has been widely studied. However, their association with rifampicin and ethambutol resistance in tuberculosis (TB) patients is still unclear. Genotype/allele/haplotype frequencies in c.
