DC. (Myrtaceae) is a native and endemic Brazilian species, and there is no information about its chemical composition. In our study, five different anthocyanins and two other phenolic compounds were described for the first time in fruits. Delphinidin 3--glucoside , cyanidin 3--glucoside , petunidin 3--glucoside , peonidin 3--glucoside , malvidin 3--glucoside , gallic acid and myricetin were identified by offline system RP-HPLC-DAD/ESI-QTOF-MS and compared to the scientific literature. Furthermore, the lyophilized powder of fruits showed a high anthocyanin content (1878.14 mg cy-3-glu eqv/100 g f.w.), with greater levels of compounds and , and an antioxidant potential in DPPH and ABTS assays (EC 2419 μg/mL and 339 μmol Trolox/g f.w.), results superior to other non-conventional Brazilian fruits. This first report about the chemical composition of fruit reveals the potential of this fruit as a new source of bioactive anthocyanins.

Background: Cutaneous tuberculosis is a rare form of the disease that defies diagnosis due to the diversity of clinical presentations. This study was based on the reality of a dermatology referral center in the Brazilian Amazon region to detail several characteristics of this disease.
Objective: To describe a series of cases of cutaneous tuberculosis treated at a dermatology service in the Brazilian Amazon region, addressing epidemiological aspects, clinical forms, diagnostic methods, treatment, and outcomes.

This study aimed to evaluate the overall excess mortality and COVID-19 mortality in the regions of Brazil, in 2020, by sex and age group. An ecological study was carried out to calculate the overall excess mortality, by sex and age group, using the expected number of deaths in a non-pandemic context and the deaths observed in 2020. Data on deaths were extracted from the Brazilian Mortality Information System, in addition to population data from the Brazilian Institute of Geography and Statistics.

Objective: To describe the polio vaccination status in 26 state capitals, the Federal District, and 12 municipalities in Brazil, among children born between 2017 and 2018.
Methods: This was a population-based household survey conducted from 2020 to 2022, which assessed polio vaccination coverage in children, considering valid, administered, and timely doses by municipality.
Results: Data were collected from 37,801 children.

Objective: To estimate measles-mumps-rubella vaccination coverage, delay and loss to follow-up in children up to 24 months old living in Brazilian cities.
Methods: Surveys and questionnaires with a retrospective cohort of live births in 2017-2018, analyzing vaccination coverage and sociodemographic data of children and families, based on vaccination card records and interviews.
Results: Valid coverage of first dose was 90.
