Objective: Compare time to recovery between initial and repeat concussions.

Design: Retrospective review of electronic medical record.

Setting: An interdisciplinary concussion clinic.

SARS-CoV-2 Immunization Index in the Academic Community: A Retrospective Post-Vaccination Study.

Background/objectives: The COVID-19 pandemic has revolutionized vaccine production and compelled a massive global vaccination campaign. This study aimed to estimate the positivity and levels of SARS-CoV-2 IgG antibodies acquired due to vaccination and infection in the academic population of a Portuguese university.

Methods: Blood samples were collected and analyzed through the ELISA methodology, and statistical analysis was performed.

Passive sampling-derived aqueous concentrations of organotins and booster biocides in the largest Port of South America (Southeastern Brazil).

Organotin compounds (OTs) used to be the most widely used biocide in antifouling paint systems, but the International Maritime Organization (IMO) banned them because of their high environmental toxicity to non-target organisms. Currently, at least 25 active ingredients are being employed as biocides in antifouling paint formulations. In the present study, silicone rubber-based passive sampling was used to determine the freely dissolved concentrations (C) of 6 OTs and 4 booster biocides in the water column at the entrance of Santos Port's main navigation channel, the largest Port of South America (southeastern Brazil).

A post-pandemic snapshot of the magnitude of COVID-19 in Brazil: A countrywide study.

Objective: To outline the features of COVID-19 in Brazil through a countrywide telephone survey.

Methods: Data from the Telephone Survey of Risk Factors for Chronic Noncommunicable Diseases During the Pandemic (Covitel), a telephone survey of individuals aged 18 years or older from all macro-regions of Brazil, were used. The questionnaire included sociodemographic characteristics and outcomes related to COVID-19 infection, severity, vaccination, and use of masks.

Effect of primary health care on the association between multimorbidity and emergency service utilization: National Health Survey, 2019.

Objective: To examine the effect of Primary Health Care (PHC) on the association between multimorbidity and emergency service utilization among adults in Brazil.

Methods: This is a cross-sectional, nationwide household-based study using data from the 2019 National Health Survey. Poisson regression was used to assess emergency service utilization among individuals with multimorbidity.
