Este artigo verifica a validade de constructo da escala apoio social utilizada em um estudo coorte trabalhadores uma universidade no Rio Janeiro, Brasil (Estudo Pró-Saúde). Os dados foram obtidos na primeira etapa do estudo, realizada 1999, qual 4.030 funcionários técnico-administrativos completaram, ambiente trabalho, questionário multidimensional e autopreenchível. Associações entre as dimensões características sócio-demográficas, relacionadas à saúde ao bem-estar, avaliadas. Por meio...
Abstract There is considerable interest in the waning of effectiveness coronavirus disease 2019 (COVID-19) vaccines and vaccine (VE) booster doses. Using linked national Brazilian databases, we undertook a test-negative design study involving almost 14 million people (~16 tests) to estimate VE CoronaVac over time BNT162b2 vaccination against RT–PCR-confirmed severe acute respiratory syndrome 2 (SARS-CoV-2) infection COVID-19 outcomes (hospitalization or death). Compared with unvaccinated...
OBJETIVO: Descrever o processo de adaptação, para português, da versão resumida "job stress scale", originalmente elaborada em inglês. MÉTODOS: Foram avaliados seis aspectos equivalência entre a escala original e português: as equivalências conceitual, semântica, operacional, itens, medidas funcional. Tomou-se por base um estudo confiabilidade teste-reteste com 94 indivíduos selecionados. RESULTADOS: O permitiu estimativas reprodutibilidade (coeficientes correlação intraclasse) dimensões...
Neglected Tropical Diseases (NTDs) are important causes of morbidity, disability, and mortality among poor vulnerable populations in several countries worldwide, including Brazil. We present the burden NTDs Brazil from 1990 to 2016 based on findings Global Burden Diseases, Injuries, Risk Factors Study (GBD 2016).We extracted data GBD assess years life lost (YLLs), lived with disability (YLDs), disability-adjusted life-years (DALYs) for by sex, age group, causes, Brazilian states, 2016....
The control of zoonotic visceral leishmaniasis is a challenge, particularly in Brazil, where the disease has been gradually spreading across country over past 30 years. Strategies employed for decreasing transmission risk are based on vector populations and reservoirs; since humans considered unnecessary maintenance transmission. Among adopted strategies sacrifice infected dogs commonly performed most controversial measure. In present study, we provide rationale implementation different...
A autoavaliação do estado de saúde é um importante indicador da percepção saúde. Este estudo visa investigar a associação entre e fatores sociodemográficos, hábitos vida morbidade na população brasileira. Trata-se seccional, baseado num inquérito nacional, que avaliou 12.324 indivíduos, nas cinco regiões geográficas país. Foram aplicados modelos regressão para avaliar o desfecho, avaliado forma dicotômica, variáveis exposição: sexo, idade, renda, escolaridade, raça, situação conjugal,...
OBJECTIVE To estimate the seroprevalence of antibodies to SARS-CoV-2 among blood donors in state Rio de Janeiro, Brazil. METHODS Data were collected on 2,857 from April 14 27, 2020. This study reports crude prevalence SARS-CoV-2, population weighted for state, and adjusted test sensitivity specificity. Logistic regression models used establish correlates prevalence. For analysis, we considered collection period site, sociodemographic characteristics, place residence. RESULTS The proportion...
Aging influences COVID-19 severity and response to vaccination, but previous vaccine effectiveness (VE) analyzes lack the power evaluate its role in subgroups within elderly age group. Here we analyzed impact of on viral vector inactivated virus vaccines' effectiveness, main platforms used low- middle-income countries.
Reports suggest that COVID-19 vaccine effectiveness is decreasing, but whether this reflects waning or new SARS-CoV-2 variants-especially delta (B.1.617.2)-is unclear. We investigated the association between time since two doses of ChAdOx1 nCoV-19 and risk severe outcomes in Scotland (where was dominant), with comparative analyses Brazil uncommon).In retrospective, population-based cohort study Scotland, we linked national databases from EAVE II Scotland; Vaccination Campaign, Acute...
<h2>Summary</h2><h3>Background</h3> Little is known about vaccine effectiveness over time among adolescents, especially against the SARS-CoV-2 omicron (B.1.1.529) variant. This study assessed associations between since two-dose vaccination with BNT162b2 and occurrence of symptomatic infection severe COVID-19 adolescents in Brazil Scotland. <h3>Methods</h3> We did test-negative, case-control studies aged 12–17 years COVID-19-related symptoms linked records RT-PCR antigen tests to national...
Although severe COVID-19 in children is rare, they may develop multisystem inflammatory syndrome, long-COVID and downstream effects of COVID-19, including social isolation disruption education. Data on the effectiveness CoronaVac vaccine scarce during Omicron period. In Brazil, between 6 to 11 years are eligible receive vaccine. We conducted a test-negative design estimate using 197,958 tests from January 21, 2022, April 15, dominant period Brazil among aged years. The estimated for...
To date, no information has been published on the effectiveness of inactivated whole-virus COVID-19 vaccines plus heterologous booster against symptomatic infection and severe outcomes (hospitalization or death) during dominance SARS-CoV-2 Omicron variant period. We evaluated vaccine (VE) CoronaVac BNT162b2 period in Brazil (January to April 2022). Using a test-negative design, we analysed data for 2,471,576 individuals tested variant's dominant using nationally linked database from Brazil....
Brazil started the COVID-19 mass vaccination in January 2021 with CoronaVac and ChAdOx1, followed by BNT162b2 Ad26.COV2.S vaccines. By end of 2021, more than 317 million vaccine doses were administered adult population. This study aimed at estimating effectiveness primary series booster shots protecting against severe cases deaths during first year vaccination.A cohort dataset over 158 records linked from official national registries was analyzed via a mixed-effects Poisson model, adjusted...
Tuberculosis (TB) is the leading infectious disease cause of death worldwide. In recent years, stringent measures to contain spread SARS-CoV-2 have led considerable disruptions healthcare services for TB in many countries. The extent which these affected testing, treatment initiation and outcomes has not been comprehensively assessed. We aimed estimate service occurring during COVID-19 pandemic Brazil, India, South Africa. obtained country-level programme laboratory data used autoregressive...
Epidemics of visceral leishmaniasis (VL) in major Brazilian cities are new phenomena since 1980. As determinants transmission urban settings probably operate at different geographic scales, and information is not available for each scale, a multilevel approach was used to examine the effect canine infection environmental socio-economic factors on spatial variability incidence rates VL city Teresina. Details an outbreak greater than 1200 cases Teresina during 1993-1996 were two hierarchical...
The effort-reward imbalance (ERI) model has been used to assess the health impact of job stress. We aimed at describing cross-cultural adaptation ERI questionnaire into Portuguese and some psychometric properties, in particular internal consistency, test-retest reliability, factorial structure. developed a Brazilian version using back-translation method tested its reliability. reliability study was conducted with 111 workers University staff. current analyses are based on 89 participants,...
INTRODUCTION: The objective of the study is to identify main risk factors for death by New World visceral leishmaniasis and establish a coherent pathogenic substrate severe disease based on clinical findings. METHODS: Seventy-six deceased inpatients 320 successfully treated with VL were studied in case control study. RESULTS: Bacterial infection bleeding mutually exclusive events leading death. Five unique bacterial (malnutrition, pulmonary rales, anemia, absolute neutropenia higher...
