Ultra-processed food consumption is related to screen time among Brazilian adolescents, adults and older adults.

This study investigated the association between screen time and ultra-processed food (UPF) consumption across the lifespan, using data from the 2019 Brazilian National Health Survey, a cross-sectional and population-based study. A score was used to evaluate UPF consumption, calculated by summing the positive answers to questions about the consumption of ten UPF subgroups on the previous day. Scores ≥5 represented high UPF consumption.

Prevalence and inequalities in contraceptive use among adolescents and young women: data from a birth cohort in Brazil.

Monitoring trends of contraceptive use and identifying the groups with less coverage are needed to guide public policies and make them more efficient. But, in Brazil, recent data about these aspects are limited. This study aimed to investigate the prevalence of contraceptive use and its inequalities during adolescence and early adulthood.

Radiation therapy with elective lymph node irradiation for breast cancer: dosimetric study and impact on cardiovascular risk and second neoplasms.

Objective: The aim of this study was to perform dosimetric analysis of radiotherapy (RT) plans with or without elective nodal irradiation (ENI) and estimate whether the increase in mean doses (MDs) in the heart and lungs with ENI may lead to late side effects that may surpass the benefits of treatment.

Methods: The dosimetric analysis of 30 treatment plans was done with or without ENI. The planning and dose-volume histograms were analyzed, and the impact on the mortality of cardiovascular and lung cancer was estimated based on the correlation of the dosimetric data with data from population studies.

Objective: To analyze the prevalence of medication use, sources of access, and associated factors among rural residents in Pelotas, RS, Brazil.

Methods: This was a cross-sectional study conducted in 2016 with adults ≥18 years old. Participants reported on medication use and sources of access to medication in the month prior to the interview.

Parental attendance in two early-childhood training programmes to improve nurturing care: A randomized controlled trial.

Parent training programmes have significant potential to improve the quality of children's early environments and thereby their development and life-course outcomes. The aim of this study was to identify and explain the extent to which parents engaged in two group-based training programmes, offered to high-risk families enrolled in a randomized controlled trial study called PIÁ in Southern Brazil.

Liposomes loaded with phenolic extracts of Spirulina LEB-18: Physicochemical characterization and behavior under simulated gastrointestinal conditions.

Liposomes composed of rice (RL) and soybean (SL) lecithins were produced by reverse phase evaporation and used for the encapsulation of phenolic extracts from Spirulina LEB-18 (S-RL and S-SL for liposomes of rice and soybean lechitin, respectively). Liposomes were characterized in terms of size distribution, polydispersity index, and ζ-potential; the chemical interactions between the phenolic compounds from Spirulina and liposomes were evaluated by Fourier Transform Infrared Spectroscopy (FTIR), and X-ray diffraction (XRD) and differential scanning calorimetry (DSC) were used to evaluate their crystallinity pattern. The release behavior of phenolic extracts was evaluated under two different pH conditions.
