Introduction: The quick spread of SARS-CoV-2 led to the development of vaccines that are capable of reducing infection and the number of more severe COVID-19 cases. Aim: To assess COVID-19 prevalence among health care workers (HCWs) after vaccination against SARS-CoV-2. Methods: Cross-sectional study on the prevalence of COVID-19 diagnosis among 7.523 HCWs vaccinated against SARS-CoV-2 with Coronavac and ChAdOx1 nCoV-19 in a university hospital, in southern Brazil, between January 18, 2021 and March 18, 2021.The variables evaluated were: sex, age, work area, role, source of infection, previous diagnosis of COVID-19, date of vaccine administration, type of vaccine, and need for hospitalization. The statistical analysis used Poisson regression and Fisher's Exact Test with the SPSS software version 25 and level of significance set at 5%. Results: 813 vaccinated HCWs showed symptoms suggestive of COVID-19, and 35.4% (288) who underwent RT-PCR for SARS-CoV-2 had a detectable result. There was a reduction of 62% in new cases of COVID-19 among HCWs in the institution after seven weeks of the start of the vaccine rollout. Conclusion: Our data suggest that the vaccines used by the institution reduced the number of COVID-19 cases among health care workers, showing the effectiveness of the vaccines.

Introduction: Cardiac involvement in COVID-19 can range from mild damage to severe myocarditis. The precise mechanism by which COVID-19 causes myocardial injury is still unknown. Myocarditis following administration of COVID-19 vaccines, especially those based on mRNA, has also been described. However, no reports of heart failure following reinfection with COVID-19 in patients immunized with an inactivated vaccine have been identified. Case description : Male, 47-year-old, of African descent, construction worker, with type II diabetes, with a history of infection by SARS-CoV-2 in December 2020 and May 2021, confirmed by RT-PCR. Received two doses of an inactivated vaccine against COVID-19. Between the two COVID-19 episodes with positive RT-PCR he had two episodes of bacterial lung infection. After the second episode of SARS-CoV-2 infection, he was diagnosed with severe heart failure as a sequelae of myocarditis. Conclusion: It is essential to do a proper follow-up after infection by SARS-CoV-2, since even with proper immunization, there is a possibility that the patient was reinfected and had severe cardiac sequelae as a consequence, and the hypothesis of an etiology associated with the use of an inactivated vaccine against COVID-19 with a potential immune enhancement mechanism following re-infection with SARS-CoV-2 cannot be rejected.

Ergonomia é uma ciência que busca estudar a relação do homem e o trabalho visando atender parâmetros que permitam a adaptação das condições de trabalho às características dos trabalhadores, de modo a proporcionar conforto, segurança e desempenho eficiente. Além disso, é um dos processos centrais para garantia de um bom ambiente de trabalho. O termo está muito associado a demandas físicas, como o mobiliário e equipamentos dos postos de trabalho. Só que, além disso, a ergonomia engloba todos os aspectos do trabalho, como as questões organizacionais (pausas, ritmo de trabalho) e cognitivas (atenção, memória, estresse). Ou seja, o objetivo da ergonomia é adaptar o trabalho às pessoas.

Introdução: A Síndrome da Imunodeficiência Adquirida (AIDS, da sua sigla em inglês), desde seu reconhecimento na década de 1980, tem sido sério problema de saúde pública em todo o mundo, especialmente em países em desenvolvimento. O disability-adjusted life years (DALY) tem sido recomendado como um indicador para análise epidemiológica por ser mais completo, porém ele é pouco utilizado no Brasil. Objetivo: Calcular o DALY de indivíduos que convivem com a AIDS e recebem benefícios previdenciários e assistenciais no Brasil, no período de 2004-2016. Métodos: Os dados foram extraídos do Sistema Único de Informações de Benefícios (SUIBE) do sistema de Previdência e Assistência Social do Brasil, de acesso restrito. O DALY foi calculado para cada indivíduo pela soma dos indicadores years of life lost due to premature death (YLL) e years lived with disability (YLD). O YLL foi estimado pela expectativa Resumos de trabalhos científicos aprovados
