Immunogenicity and Safety According to Immunosuppressive Drugs and Different COVID-19 Vaccine Platforms in Immune-Mediated Disease: Data from SAFER Cohort.

Background/objectives: The effectiveness of COVID-19 vaccine in patients with immune-mediated inflammatory diseases (IMID) depends on the underlying disease, immunosuppression degree and the vaccine regimens. We evaluate the safety and immunogenicity of different COVID-19 vaccine schedules.

Methods: The SAFER study: "Safety and effectiveness of the COVID-19 Vaccine in Rheumatic Disease", is a Brazilian multicentric prospective observational phase IV study in the real-life.

Generational Differences in Self-Esteem and Vocal Perception Among Brazilian Gay Men.

Introduction: Self-esteem and vocal perception are central aspects of identity and self-presentation, particularly within marginalized communities where voice and self-concept can be deeply intertwined with social acceptance and cultural dynamics. Among Brazilian gay men, generational differences in these areas may reflect broader social changes, shifts in stigma, and evolving notions of masculinity. This study aims to explore these differences, examining how self-esteem and self-assessed vocal descriptions vary across generations, thereby shedding light on specific needs and areas for potential support within these communities.

A portrait of germline pathogenic variants in high and moderate penetrance breast cancer genes in Brazil.

Introduction: The prevalence of germline pathogenic/likely pathogenic variants (P/LP) in high and moderate penetrance (HMP) genes is approximately 7%-10% among breast cancer (BC) patients. The prevalence and spectrum of BC P/LP variants are affected by several factors. There are limited genetic data from Brazilian patients with BC.

ADP-ribosyltransferase-based biocatalysis of non-hydrolyzable NAD+ analogs.

Enzyme promiscuity is the ability of an enzyme to catalyze an unexpected side reaction in addition to its main reaction. Here, we describe a biocatalytic process to produce non-hydrolyzable NAD+ analogs based on the ADP-ribosyltransferase (ART) activity of pertussis toxin PtxS1 subunit. First, in identical manner to normal catalysis, PtxS1 activates NAD+ to form the reactive oxocarbenium cation.

Active Commuting in Brazil: A Systematic Review and Meta-Analysis of Proportions.

Background: Active commuting benefits both individual and planetary health. Estimating commuting behavior is desirable, although very challenging in large and regionally relevant nations like Brazil.

Methods: This review (CRD42023431054) included observational studies that estimated prevalence of active commuting in Brazil for adults (≥18 y).
