Impact of Variants, Epidemiological Trends, and Comorbidities on Hospitalization Rates of Unvaccinated Children in Brazil: A Retrospective Study (2020-2022).

This retrospective study aimed to investigate the impact of the emergence of new variants and the epidemiological scenario on hospitalization rates of unvaccinated children (0-12 years) in Brazil. The study included 1614 children admitted to a hospital between March 2020 and December 2022 but 101 (6.3%) of them testing positive for COVID-19 via RT-PCR.

Knowledge of contraceptive methods among deaf women: a qualitative study.

Objective: To analyse the understanding of deaf women regarding contraceptive methods.

Method: We conducted a qualitative descriptive study in two referral centres for sexual and reproductive health (SRH) in São Paulo, Brazil, trough years 2020-2022. Twenty-eight deaf women who use Brazilian Sign Language (LIBRAS) were interviewed face-to-face and remotely via videocall using a semi-structured questionnaire containing sociodemographic and clinical data and questions about understanding and knowledge of contraceptive methods.

Thinking outside the shoulder: A systematic review and metanalysis of kinetic chain characteristics in non-athletes with shoulder pain.

Introduction: The kinetic chain is important in the proximal-distal energy transfer along body segments. Although biomechanical impairments in components of the kinetic chain have already been reported in athletes with shoulder pain, such investigations in non-athlete individuals have not yet been synthesized.

Objective: To systematically review the literature and analyze the quality of evidence on the characteristics of the kinetic chain of non-athletes with shoulder pain compared to asymptomatic individuals.

Higher frequency of interstate over international transmission chains of SARS-CoV-2 virus at the Rio Grande do Sul - Brazil state borders.

Brazil's COVID-19 response has faced challenges due to the continuous emergence of variants of concern (VOCs), emphasizing the need for ongoing genomic surveillance and retrospective analyses of past epidemic waves to reassess and fine tune containment protocols. Rio Grande do Sul (RS), Brazil's southernmost state, has international borders and trades with Argentina and Uruguay, along with significant domestic connections within Brazil. The identification of source and sink transmission chains at national and international scales can identify main hubs and pathways to target future interventions.

Effects of multiple cold-water immersion during pre-season on recovery performance in under-20 male soccer players: A randomized controlled trial.

Introduction: This study was designed to evaluate the effects of multiple cold-water immersions performed daily during the preseason period on biochemical, clinical, and neuromuscular aspects of muscle damage of soccer players.

Methods: This two-arm, prospectively registered, randomized controlled trial, blinded to statistician and assessors, was conducted at professional football club facilities. Twenty-three under-20 semi-professionals male soccer players were randomly allocated into cold water immersion group (bathtub with water and ice at 10 °C ± 1 °C for 10 min) or control group (rest for 10 min), every day, after training sessions during a preseason.
