Tendências temporais e agrupamentos regionais dos desfechos da coinfecção tuberculose-HIV no Brasil
OBJECTIVE: To investigate the temporal trends and regional clusters of tuberculosis treatment outcomes among people with HIV in Brazil, as well as their relationship with socioeconomic and programmatic indicators. METHODS: Ecological study with data from people living with HIV who initiated and completed tuberculosis treatment from 2015 to 2021 in Brazil. We described the semiannual trends of cure, treatment interruption, and death rates in Brazi…
Is chemical exposure present in informal work associated with Sars-CoV-2 infection
OBJECTIVE: To compare the incidence of Covid-19 symptoms between informal home-based workers and a control group and to assess the association of these cases with blood elements concentrations and other relevant risk factors for Sars-Cov-2 infection. METHODS: Welders chemically exposed to potentially toxic elements (PTEs) (n = 26) and control participants (n = 25) answered questionnaires on adherence to social distancing and signs and symptoms of…
Mercury Exposure in Women of Reproductive Age in Rondônia State, Amazon Region, Brazil
Environmental contamination by mercury (Hg) is a problem of global scale that affects human health. This study's aim was to evaluate Hg exposure among women of reproductive age residing in the Madeira River basin, in the State of Rondônia, Brazilian Amazon. This longitudinal cohort study used linear regression models to assess the effects on Hg levels of breastfeeding duration at 6 months, and of breastfeeding duration and number of new children …
Experiencia y percepción del riesgo asociados a conocimientos, actitudes y prácticas sobre dengue en Riohacha, Colombia
Para el control del dengue es esencial el reconocimiento de los determinantes de los conocimientos, actitudes y prácticas (CAP), los cuales podrían estar condicionados por las experiencias y percepciones de la población a riesgo. El propósito de este artículo es estimar la asociación entre la percepción del riesgo y la experiencia de dengue con los CAP sobre dengue, en una población endémica de Colombia. Estudio analítico de corte transversal y m…
Factors associated with diarrheal disease in the rural Caribbean region of Colombia
OBJECTIVE: To analyze factors associated with diarrheal disease in the rural Caribbean region of Colombia. METHOD: A cross-sectional study conducted in the rural area of the Cesar Department, Colombia, between November 2017 and June 2018. Self-reported cases of diarrheal disease were surveyed, and water samples from 42 households were collected and analyzed. Descriptive statistics were employed in the analysis of socioeconomic status, environment…
Translating transmissibility measures into recommendations for coronavirus prevention
The rapid increase in clinical cases of the new coronavirus disease, COVID-19, suggests high transmissibility. However, the estimates of the basic reproductive number reported in the literature vary widely. Considering this, we drew the function of contact-rate reduction required to control the transmission from both detectable and undetectable sources. Based on this, we offer a set of recommendations for symptomatic and asymptomatic populations …
Variabilidade climática e internações por doenças diarreicas infecciosas em um município da Amazônia Ocidental brasileira
A morbimortalidade por doenças diarreicas infecciosas ainda representa um grave problema de saúde no Brasil e está altamente relacionada a fatores como condições climáticas, ambientais e de vida da população. O objetivo deste estudo foi analisar a associação das taxas de internações por doenças diarreicas infecciosas na população do município de Rio Branco/AC com a precipitação, o nível do rio, a umidade e a temperatura, entre os anos de 2000 e 2…
Oferta de serviços pela atenção básica e detecção da incidência de tuberculose no Brasil
OBJETIVO: Avaliar a associação entre os serviços de saúde ofertados por equipes de atenção básica e a detecção de casos novos de tuberculose no Brasil. MÉTODOS: Estudo ecológico, abrangendo todos os municípios brasileiros que registraram pelo menos um caso novo de tuberculose (diagnosticado entre 2012 a 2014 e notificado no Sistema de Informação de Agravos de Notificação) e com pelo menos uma equipe de atenção básica avaliada pelo segundo ciclo d…
Respiratory Condition of Family Farmers Exposed to Pesticides in the State of Rio de Janeiro, Brazil
Pesticide exposure is a growing public health concern. Although Brazil is the world’s largest consumer of pesticides, only a few studies have addressed the health effects among farmers. This study aimed to evaluate whether pesticide exposure is associated with respiratory outcomes among rural workers and relatives in Brazil during the crop and off-seasons. Family farmers (82) were interviewed about occupational history and respiratory symptoms, a…
Association between the level of education and knowledge, attitudes and practices regarding dengue in the Caribbean region of Colombia
Level of education could be a key determinant of knowledge of the disease and its transmission, as well as attitudes and practices, especially those that involve the integration of community efforts for dengue control
Zika-Associated Microcephaly Epidemic and Birth Rate Reduction in Brazilian Cities
Objectives. To estimate birth reduction potentially in response to Zika virus–associated microcephaly among the 36 largest Brazilian cities. Methods. We analyzed the number of live births per month on the basis of information on approximately 8.2 million births from all of Brazil’s state capitals and cities that had more than 10 000 annual births. Results. In the second half of 2016, the live birth rate was reduced by 7.78% (95% confidence interv…
Cadastro Nacional de Estabelecimentos de Saúde como ferramenta de análise da descentralização do atendimento da tuberculose para a atenção básica
Os objetivos deste artigo foram validar um método de classificação dos serviços de saúde (atenção básica vs. outros níveis) e descrever a descentralização do atendimento da tuberculose (TB) para a atenção básica no Brasil no período de 2002 a 2016. Os serviços de saúde que notificaram e acompanharam pessoas com TB foram classificados como "atenção básica" ou "outros níveis", considerando-se o tipo de estabelecimento registrado no Cadastro Naciona…
Evaluation of dengue fever reports during an epidemic, Colombia
OBJECTIVE To assess the validity of dengue fever reports and how they relate to the definition of case and severity. METHODS Diagnostic test assessment was conducted using cross-sectional sampling from a universe of 13,873 patients treated during the fifth epidemiological period in health institutions from 11 Colombian departments in 2013. The test under analyses was the reporting to the National Public Health Surveillance System, and the referen…
A prospective cohort study to evaluate peridomestic infection as a determinant of dengue transmission
Results indicating a high infection rate among the exposed subjects would justify the application of peridomestic control measures and call for an evaluation of alternate causes for insufficient program impact. On the other hand, a low incidence of peridomestic-infected subjects would support the hypothesis that infection occurs outside the domicile, and would thus explain why the vector control measures applied in the past have exerted such a li…
