    There are many challenges in minimizing the gaps between scientific evidence and better health outcomes. The translation of knowledge (TC) is the movement that knowledge makes in an organizational context in favor of its effective application. This study aimed to analyze the occurrence of CT in the Executive Secretariat of Health Surveillance of Pernambuco (SEVS / PE), focusing on 10 evaluative surveys on Health Surveillance programs, produced in the Master's Degree in Health Evaluation of the Institute of Comprehensive Medicine Prof. Fernando Figueira, from 2011 to 2015. For this purpose, a semi-structured interview script was used, addressing 7 managers and 10 SEVS-PE technicians. In the analysis of this qualitative case study, a CT model was used, and overlapping it, a theoretical structure of use-influence of the evaluation. In eight studies analyzed, evidence was categorized into five phases of CT. Only the evaluation stage of the use of knowledge was not evidenced. Different types of use, dimensions and influence levels of the evaluations were reported. Among the changes occurred, the following were reported: creation of new agendas, elaboration of protocols, change of work process, creation of new flows, hiring of new professionals.publishersversionpublishe

    O índice glicêmico (IG) é uma nova e excitante ferramenta nutricional que pode contribuir para uma ótima intervenção, representando a qualidade do carboidrato dos alimentos, que pode ser classificado em baixo, moderado e alto. A pesquisa tem como objetivo avaliar, por meio de revisão bibliográfica, uma análise do consumo alimentar de praticantes de musculação segundo índice glicêmico dos alimentos consumidos e a a influência do IG dos alimentos no desempenho e no rendimento do treinamento de hipertrofia muscular, bem como sua aplicabilidade nos períodos antes, durante e após o treinamento. Para a pesquisa foi realizada uma revisão da literatura nas bases de dados: Scielo, Google acadêmico; Pepsic, sendo critérios de inclusão: artigos, resoluções e portarias em português e seus respectivos descritores em inglês e espanhol. Critérios de exclusão; artigos em comum nas bases de dados e artigos de revisões sistemáticas, integrativas. Os resultados permitiram-nos demonstrar a importância da aplicabilidade do IG no planejamento de estratégias nutricionais. Assim, concluímos que a utilização de carboidratos de alto IG no pré-treino pode afetar o rendimento e que carboidratos de baixo IG são mais indicados. Em contraste, carboidratos de alto IG são mais indicados no pós-treino. Entretanto, muitas lacunas precisam ser preenchidas, evidenciando a necessidade de aprofundamento quanto ao relacionamento entre carboidratos, IG e rendimento

    O desempenho dos sistemas e políticas de saúde estão intimamente relacionados à capacidade de alcançar objetivos e metas, dentro de um contexto de claras prioridades de governança. Nesta perspetiva, a Gestão do Desempenho (GD), qual seja um conjunto de elementos e procedimentos que ajustam taticamente ações delineadas para garantir o alcance de resultados, parece cumprir esse propósito. O objetivo desse estudo foi avaliar a Política de M&A da Secretaria Executiva de Vigilância em Saúde de Pernambuco (SEVS), com base nesse modelo. Foi realizada uma avaliação normativa, utilizando-se uma abordagem descritivo-qualitativa partindo-se do desenho do modelo lógico da GD e de critérios pré-estabelecidos. Foram entrevistados 10 informantes-chave e analisados documentos. A Política de M&A da SEVS é convergente com o modelo de Gestão do Desempenho, a partir dos componentes propostos na análise: liderança do desempenho, estrutura gerencial e produção de informação e conhecimento. O M&A são elementos chave nesse processo, porém é preciso diferenciá-los e buscar estratégias que os perenizem. Mais amiúde, o Monitoramento do Desempenho da Gestão da Vigilância em Saúde revela-se o impulsionador da sustentabilidade da Política. A avaliação precisa assumir uma agenda mais permanente na SEVS, como parte do desempenho que se persegue. The performance of systems and health policies is closely related to their capacity of reaching objectives and goals within a context of clear governance priorities. In this perspective, Performance Management (GD), which is a set of elements and procedures that tactically adjust actions outlined to ensure the achievement of results, seems to fulfill this purpose. The objective of this study was to evaluate the Monitoring and Evaluation Policy used by the Executive Secretariat for Health Surveillance of Pernambuco (SEVS), based of this model. A normative evaluation was carried out, using a qualitative descriptive approach starting with the design of the PM logical model and pre-established criteria. For this study, we interviewed 10 key informants and documents were analyzed. The SEVS M & E Policy is convergent with the Performance Management model, based on the components proposed in the analysis: performance leadership, management structure and production of information and knowledge.The M & E are key elements in this process, but it is necessary to differentiate them and seek strategies that will keep them alive. More often than not, monitoring the performance of Health Surveillance Management is the driving force behind the sustainability of the Policy. The evaluation needs to take on a more permanent agenda at SEVS, as part of the performance that is pursued.publishersversionpublishe

    Remote sensing through band ratio techniques for nutritional monitoring of clonal eucalyptus plantations is essential to guarantee health and productivity, reducing costs of forestry enterprises. The objective was to apply vegetation indices from high resolution satellite images in the nutritional diagnosis of macronutrients in plantations of clonal hybrids of Eucalyptus urophylla S. T. Blake. The study was carried out in 62 areas of six municipalities in the state of Bahia under cultivation of homogeneous eucalyptus plantations, aged between 1.3 and 1.8 years. The design was completely randomized with six treatments constituted by the rainfall regime (1000 to 1300 mm year-1 and 1300 to 1600 mm year-1) and soil types (class and texture). The nutritional diagnosis of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) was performed from leaf analysis and determination of vegetation indices: normalized difference vegetation (NDVI), normalized difference water index (NDWI) and soil adjusted vegetation index (SAVI). The evaluated areas have high vigor (NDVI > 0.70) and the highest values were observed in the rainy regions (1300 to 1600 mm year-1) (mean of 0.78). The NDWI index presents the highest correlation for the average levels of Ca and Mg. The NDVI, NDWI and SAVI indexes present a strong correlation with each other (-0.97 to 1.00) and can help in mapping vigor and consequently in eucalyptus productivity.O sensoriamento remoto, por meio das técnicas de razão de bandas para o monitoramento nutricional de plantios clonais de eucalipto, é fundamental para garantir a sanidade, produtividade e reduzir custos de empreendimentos florestais. Objetivou-se aplicar índices de vegetação a partir de imagens de satélite de alta resolução na diagnose nutricional de macronutrientes em plantios de híbridos clonais de Eucalyptus urophylla S. T. Blake. O estudo foi realizado em 62 áreas de seis municípios do estado da Bahia sob cultivo de plantios homogêneos de eucalipto, com idades entre 1,3 e 1,8 anos. O delineamento foi inteiramente casualizado com seis tratamentos constituídos pelo regime pluviométrico (1000 a 1300 mm ano-1 e 1300 a 1600 mm ano-1) e tipos de solo (classe e textura). A diagnose nutricional de nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca), magnésio (Mg) e enxofre (S) foi realizada a partir da análise foliar e da determinação dos índices de vegetação: índice de vegetação por diferença normalizada (NDVI), índice de diferença normalizada da água (NDWI) e índice de vegetação ajustado ao solo (SAVI). As áreas avaliadas possuem alto vigor (NDVI > 0,70) e os maiores valores foram observados nas regiões chuvosas (1300 a 1600 mm ano-1) (médio de 0,78). O índice NDWI apresenta maior correlação para os teores médios de Ca e Mg. Os índices NDVI, NDWI e SAVI apresentam forte correlação entre si (-0,97 a 1,00) e podem auxiliar no mapeamento do vigor e consequentemente na produtividade de eucalipto

    Modelos Digitais de Elevação (MDE) são informações importantes nos estudos de dinâmica costeira em distintas aplicações porque fornecem um modelo da topografia da superfície do terreno em três dimensões e são fundamentais para a avaliação de riscos de inundações em áreas baixas. A bacia hidrográfica do rio Bacanga fica localizada na cidade de São Luis-MA, o Rio Bacanga tem 105,9km² de área e teve sua hidrologia muito alterada pela construção da barragem do Bacanga, construída nas décadas de 1960 e 1970. O objetivo da presente pesquisa foi organizar um modelo conceitual e traduzir os preceitos teóricos do modelo conceitual a uma linguagem de programação, bem como inserir o código fonte do modelo e o banco de dados geográficos na plataforma e modelagem. Contudo pode-se inferir que, para a cota de inundação simulada, ou seja, canal 4,70m e inundação de 1,20m observa-se que as cotas altimétricas que não são inundados são aquelas superiores a 5 metros. Dessa forma, indica-se uma cota de segurança de 5,10m para qualquer empreendimento que possa ser construído na área

    This paper provided a list of all new Brazilian Hexapoda species described in 2020. Furthermore, based on the information extracted by this list, we tackled additional questions regarding the taxa, the specialists involved in the species descriptions as well as the journals in which those papers have been published. We recorded a total of 680 new Brazilian species of Hexapoda described in 2020, classified in 245 genera, 112 families and 18 orders. These 680 species were published in a total of 219 articles comprising 423 different authors residing in 27 countries. Only 30% of these authors are women, which demonstrates an inequality regarding sexes. In relation to the number of authors by species, the majority of the new species had two authors and the maximum of authors by species was five. We also found inequalities in the production of described species regarding the regions of Brazil, with Southeast and South leading. The top 10 institutions regarding productions of new species have four in the Southeast, two at South and with one ate North Region being the outlier of this pattern. Out of the total 219 published articles, Zootaxa dominated with 322 described species in 95 articles. The average impact factor was of 1.4 with only seven articles being published in Impact Factors above 3, indicating a hardship on publishing taxonomic articles in high-impact journals.The highlight of this paper is that it is unprecedent, as no annual record of Hexapoda species described was ever made in previous years to Brazil.Fil: Silva Neto, Alberto Moreira.

    High anti-SARS-CoV-2 antibody seroconversion rates before the second wave in Manaus, Brazil, and the protective effect of social behaviour measures: results from the prospective DETECTCoV-19 cohort

    Get PDF
    Background: The city of Manaus, Brazil, has seen two collapses of the health system due to the COVID-19 pandemic. We report anti-SARS-CoV-2 nucleocapsid IgG antibody seroconversion rates and associated risk factors in Manaus residents before the second wave of the epidemic in Brazil. Methods: A convenience sample of adult (aged ≥18 years) residents of Manaus was recruited through online and university website advertising into the DETECTCoV-19 study cohort. The current analysis of seroconversion included a subgroup of DETECTCoV-19 participants who had at least two serum sample collections separated by at least 4 weeks between Aug 19 and Oct 2, 2020 (visit 1), and Oct 19 and Nov 27, 2020 (visit 2). Those who reported (or had no data on) having a COVID-19 diagnosis before visit 1, and who were positive for anti-SARS-CoV-2 nucleocapsid IgG antibodies at visit 1 were excluded. Using an in-house ELISA, the reactivity index (RI; calculated as the optical density ratio of the sample to the negative control) for serum anti-SARS-CoV-2 nucleocapsid IgG antibodies was measured at both visits. We calculated the incidence of seroconversion (defined as RI values ≤1·5 at visit 1 and ≥1·5 at visit 2, and a ratio >2 between the visit 2 and visit 1 RI values) during the study period, as well as incidence rate ratios (IRRs) through cluster-corrected and adjusted Poisson regression models to analyse associations between seroconversion and variables related to sociodemographic characteristics, health access, comorbidities, COVID-19 exposure, protective behaviours, and symptoms. Findings: 2496 DETECTCoV-19 cohort participants returned for a follow-up visit between Oct 19 and Nov 27, 2020, of whom 204 reported having COVID-19 before the first visit and 24 had no data regarding previous disease status. 559 participants were seropositive for anti-SARS-CoV-2 nucleocapsid IgG antibodies at baseline. Of the remaining 1709 participants who were seronegative at baseline, 71 did not meet the criteria for seroconversion and were excluded from the analyses. Among the remaining 1638 participants who were seronegative at baseline, 214 showed seroconversion at visit 2. The seroconversion incidence was 13·06% (95% CI 11·52–14·79) overall and 6·78% (5·61–8·10) for symptomatic seroconversion, over a median follow-up period of 57 days (IQR 54–61). 48·1% of seroconversion events were estimated to be asymptomatic. The sample had higher proportions of affluent and higher-educated people than those reported for the Manaus city population. In the fully adjusted and corrected model, risk factors for seroconversion before visit 2 were having a COVID-19 case in the household (IRR 1·49 [95% CI 1·21–1·83]), not wearing a mask during contact with a person with COVID-19 (1·25 [1·09–1·45]), relaxation of physical distancing (1·31 [1·05–1·64]), and having flu-like symptoms (1·79 [1·23–2·59]) or a COVID-19 diagnosis (3·57 [2·27–5·63]) between the first and second visits, whereas working remotely was associated with lower incidence (0·74 [0·56–0·97]). Interpretation: An intense infection transmission period preceded the second wave of COVID-19 in Manaus. Several modifiable behaviours increased the risk of seroconversion, including non-compliance with non-pharmaceutical interventions measures such as not wearing a mask during contact, relaxation of protective measures, and non-remote working. Increased testing in high-transmission areas is needed to provide timely information about ongoing transmission and aid appropriate implementation of transmission mitigation measures.

    Differential Regional Immune Response in Chagas Disease

    Get PDF
    Following infection, lymphocytes expand exponentially and differentiate into effector cells to control infection and coordinate the multiple effector arms of the immune response. Soon after this expansion, the majority of antigen-specific lymphocytes die, thus keeping homeostasis, and a small pool of memory cells develops, providing long-term immunity to subsequent reinfection. The extent of infection and rate of pathogen clearance are thought to determine both the magnitude of cell expansion and the homeostatic contraction to a stable number of memory cells. This straight correlation between the kinetics of T cell response and the dynamics of lymphoid tissue cell numbers is a constant feature in acute infections yielded by pathogens that are cleared during the course of response. However, the regional dynamics of the immune response mounted against pathogens that are able to establish a persistent infection remain poorly understood. Herein we discuss the differential lymphocyte dynamics in distinct central and peripheral lymphoid organs following acute infection by Trypanosoma cruzi, the causative agent of Chagas disease. While the thymus and mesenteric lymph nodes undergo a severe atrophy with massive lymphocyte depletion, the spleen and subcutaneous lymph nodes expand due to T and B cell activation/proliferation. These events are regulated by cytokines, as well as parasite-derived moieties. In this regard, identifying the molecular mechanisms underlying regional lymphocyte dynamics secondary to T. cruzi infection may hopefully contribute to the design of novel immune intervention strategies to control pathology in this infection

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
