COVID-19 cross-sectional study in Maricá, Brazil: The impact of vaccination coverage on viral incidence.

Population surveillance in COVID-19 Pandemic is crucial to follow up the pace of disease and its related immunological status. Here we present a cross-sectional study done in Maricá, a seaside town close to the city of Rio de Janeiro, Brazil. Three rounds of study sampling, enrolling a total of 1134 subjects, were performed during May to August 2021. Here we show that the number of individuals carrying detectable IgG antibodies and the neutralizing antibody (NAb) levels were greater in vaccinated groups compared to unvaccinated ones, highlighting the importance of vaccination to attain noticeable levels of populational immunity against SARS-CoV-2. Moreover, we found a decreased incidence of COVID-19 throughout the study, clearly correlated with the level of vaccinated individuals as well as the proportion of individuals with detectable levels of IgG anti-SARS-CoV-2 and NAb. The observed drop occurred even during the introduction of the Delta variant in Maricá, what suggests that the vaccination slowed down the widespread transmission of this variant. Overall, our data clearly support the use of vaccines to drop the incidence associated to SARS-CoV-2.

[Adherence to standard precautions by the public pre-hospital health team in Belo Horizonte, Minas Gerais State, Brazil]. / Adesão às precauções padrão pela equipe do atendimento pré-hospitalar móvel de Belo Horizonte, Minas Gerais, Brasil.

This was a cross-sectional study of workers in the pre-hospital care team in Belo Horizonte, Minas Gerais State, Brazil, aimed at evaluating adherence to precautions. The study instrument included questions on knowledge, attitudes, and facilitating factors for adherence to standard precautions. Adherence was verified by percentage of adequacy: > 75% correct answers. Drivers showed the lowest degree of knowledge and physicians the highest. In self-reported answers, none of the workers demonstrated adequate use of face masks, goggles, or personal protective equipment (PPE), and drivers reported inadequate attitudes on all the items. In the univariate analysis, job position, gender, and specific rescue unit were associated with adoption of precautions. Meanwhile, in the multivariate analysis, only job position was related (drivers and nurse technicians/aides). The most frequently cited facilitating factors for improvement of adherence were: training focusing on infections, occupational risks, and use of PPE; periodic team meetings; and creation of a central unit for cleaning, disinfecting, and sterilizing equipment and materials. Workers in the pre-hospital care service demonstrated attitudes that were compatible with knowledge, but professional class affected knowledge on standard precautions and self-reported adequate attitudes.

Estudo transversal com profissionais do Serviço de Atendimento Pré-hospitalar de Belo Horizonte, Minas Gerais, Brasil, com o objetivo de avaliar a adesão às precauções padrão. Instrumento constou de questões sobre conhecimento, atitude e fatores facilitadores à adesão das precauções. Para verificar a adesão considerou-se percentual de adequação: > 75 por cento de respostas corretas. Condutores apresentaram menor e médicos maior grau de conhecimento. No relato das atitudes, profissionais não alcançaram adequação para uso de máscara facial, óculos e equipamento proteção individual (EPI), e, condutores relataram atitude inadequada para todos itens. Na análise univariada, categoria profissional, sexo e unidade de lotação foram associados à adoção das precauções. Já na multivariada, apenas categoria profissional (condutor e técnico/auxiliar enfermagem). Fatores facilitadores mais citados para melhorar adesão foram: treinamentos sobre infecções, riscos ocupacionais e uso de EPI; reuniões periódicas de equipe; e criação de central para limpeza, desinfecção e esterilização de material. Profissionais do Serviço de Atendimento Pré-hospitalar demonstraram atitudes compatíveis com conhecimento. No entanto, a profissão interferiu no conhecimento das medidas de precaução e no relato de atitudes adequadas.

Depressão na esquizofrenia: prevalência e relação com a qualidade de vida / Depression in schizophrenia: prevalence and relationship to quality of life

O objetivo deste estudo foi mensurar a prevalência de depressão na esquizofrenia, investigando os fatores associados e sua relação com a qualidade de vida. Foi conduzido um estudo transversal com 150 pacientes ambulatoriais, a depressão foi mensurada pela Escala Calgary de Depressão na Esquizofrenia e a qualidade de vida por meio da escala Quality of Life Scale-Brasil. Foi encontrada uma prevalência de 56 por cento de depressão maior. Pacientes com depressão maior apresentaram pior qualidade de vida na escala global e domínio ocupacional. A qualidade de vida global foi importante para a separação dos grupos na árvore de decisão. Em pacientes com pior qualidade de vida, presença de sintomas da doença, número de medicamentos e ausência de atividades no lar se associaram à depressão, enquanto para aqueles com melhor qualidade de vida, apenas duração da doença foi importante. Esta investigação sugere alta prevalência de depressão, além de mostrar sua repercussão na qualidade de vida. Recomenda-se a investigação da depressão associada à qualidade de vida no cuidado terapêutico destes pacientes.

This study aimed to investigate the prevalence of depression in schizophrenia and associated factors, including quality of life. A cross-sectional study was conducted with 150 outpatients. The Calgary Depression Scale for Schizophrenia measured depression, and the Quality of Life Scale-Brazil measured quality of life. Major depression was found in 56 percent of patients with schizophrenia. Patients with major depression had low quality of life according to both the global scale and the occupational subscale. Global quality of life was important for separating the decision-tree statistical analyses. In patients with low quality of life, three factors were associated with depression: presence of schizophrenic symptoms, number of medications, and lack of household activities. In patients with better quality of life scores, only duration of the illness was significant. The study shows a high prevalence of depression in schizophrenia, besides highlighting its repercussions on quality of life. When evaluating quality of life, the presence of depression should be taken into consideration.
