Objective: to describe epidemiological and clinical characteristics of monkeypox (MPX) in Brazil, from the identification of the first case, on June 7, 2022, to Epidemiological Week (EW) 39, ending on October 1, 2022.
Methods: this was a descriptive study of cases notified to the Ministry of Health; trends were analyzed based on the number of confirmed and probable cases per EW; the cases were also described according to demographic and clinical variables.
Results: out of 31,513 notifications, 23.
Background: Brazil lacks data from syphilis in its border areas. We aimed to describe the spatial and temporal distribution of acquired syphilis (AS), in pregnancy (SP) and congenital syphilis (CS) in Brazilian municipalities in the arches border contexts.
Methods: An ecological, cross-sectional study was conducted from 2010 to 2020.
Background: The credibility of a study and its internal and external validity depend crucially on the quality of the data produced. An in-depth knowledge of quality control processes is essential as large and integrative epidemiological studies are increasingly prioritized.
Objective: This study aimed to describe the stages of quality control in the POP-Brazil study and to present an analysis of the quality indicators.
Background: Atypical Hemolytic Uremic Syndrome (aHUS) is an ultra-rare disease that potentially leads to kidney graft failure due to ongoing Thrombotic Microangiopathy (TMA). The aim was evaluating the frequency of TMA after kidney transplantation in patients with aHUS in a Brazilian cohort stratified by the use of the specific complement-inhibitor eculizumab.
Methods: This was a multicenter retrospective cohort study including kidney transplant patients diagnosed with aHUS.
Objective: To investigate the association between several anthropometric measurements of obesity with the incidence of hypertension.
Research Methods And Procedures: Participants were 592 individuals free of hypertension, selected at random from the community. In the baseline evaluation, they were submitted to completed measures of demographics, anthropometrics, blood pressure, and other risk factors for hypertension.
Objective: Our aim was to investigate risk factors for cardiovascular disease (CVD) in a population-based Brazilian cohort.
Design And Methods: A cohort study was conducted with 1091 individuals identified through multi-stage probability sampling in Porto Alegre, Brazil. Risk factors were investigated among demographic and anthropometric characteristics, including education, smoking habits, income, alcoholic beverage consumption, and blood pressure.
