    OBJECTIVE To characterize the profile of patients hospitalized for mental and behavioral disorders by the Unified Health System (SUS) in Brazil between 2000 and 2014, and to verify how aspects of the new mental health policy influenced the rate of hospitalized patients in that period. METHODS Non-concurrent prospective cohort study using secondary data from inpatients with a primary diagnosis of mental and behavioral disorders between 01/01/2000 and 12/31/2014. Sociodemographic, clinical, and hospital characteristics variables were selected. Overall rates of hospitalized patients were calculated according to reason for admission, type of hospital, legal nature, and number of admissions per year for each patient. The association between rates of hospitalized patients, number of psychiatric beds per year, and number of Psychosocial Care Centers per year were tested. RESULTS We selected a total of 1,549,298 patients, whose most frequent diagnoses on first admission were psychoactive substance use disorders, followed by schizophrenia and mood disorders. The median of hospitalizations per patient was 1.9 and the length of stay per patient was 29 days. The overall rate of hospitalized patients was reduced by almost half in the period. The number of beds per year was positively associated with the rates of hospitalized patients; the number of CAPS per year was negatively associated with some rates of hospitalized patients. CONCLUSION Even in the face of adversity, the National Mental Health Policy has advanced in its goal of progressively reducing hospital beds and increasing the supply of substitute services such that both strategies were associated with the reduced inpatient rates. But the changes were felt with greater intensity in the first years of the policy’s implementation, becoming less pronounced in recent years.OBJETIVO Caracterizar o perfil dos pacientes que foram internados por transtornos mentais e comportamentais pelo Sistema Único de Saúde (SUS) no Brasil entre 2000 e 2014, bem como verificar como aspectos da nova política de saúde mental influenciaram a taxa de pacientes internados no referido período. MÉTODOS Estudo de coorte prospectiva não concorrente utilizando dados secundários de pacientes internados com diagnóstico primário de transtornos mentais e comportamentais entre 01/01/2000 e 31/12/2014. Foram selecionadas variáveis sociodemográficas, clínicas e de características do hospital, além disso, foram calculadas as taxas gerais de pacientes internados segundo motivo de internação, tipo de hospital, natureza jurídica e número de internações de cada paciente por ano. Foi testada a associação entre taxas de pacientes internados, número de leitos psiquiátricos por ano e número de Centros de Atenção Psicossocial por ano. RESULTADOS Foram selecionados 1.549.298 pacientes dos quais os diagnósticos mais frequentes na primeira internação foram os transtornos devidos ao uso de substâncias psicoativas, seguidos por esquizofrenia e transtornos de humor. A mediana de internações por paciente foi de 1,9 e a de tempo de internação por paciente foi de 29 dias. A taxa geral de pacientes internados foi reduzida à quase metade no período. O número de leitos por ano apresentou associação positiva com as taxas de pacientes internados, e o número de CAPS por ano teve associação negativa com algumas taxas de pacientes internados. CONCLUSÃO Verificou-se que, mesmo diante de um contexto de adversidades, a Política Nacional de Saúde Mental avançou em suas metas de reduzir progressivamente os leitos hospitalares e aumentar a oferta de serviços substitutivos de tal modo que ambas as estratégias foram associadas à redução das taxas de pacientes internados. Contudo, as mudanças foram percebidas com maior intensidade nos primeiros anos de implantação da política, tornando-se menos pujante nos últimos anos

    OBJECTIVE: To determine the items of the Brazilian National Program for Improving Access and Quality of Primary Care that better evaluate the capacity to provide mental health care. METHODS: This is a cross-sectional study carried out using the Graded Response Model of the Item Response Theory using secondary data from the second cycle of the National Program for Improving Access and Quality of Primary Care, which evaluates 30,523 primary care teams in the period from 2013 to 2014 in Brazil. The internal consistency, correlation between items, and correlation between items and the total score were tested using the Cronbach’s alpha, Spearman’s correlation, and point biserial coefficients, respectively. The assumptions of unidimensionality and local independence of the items were tested. Word clouds were used as one way to present the results. RESULTS: The items with the greatest ability to discriminate were scheduling of the agenda according to risk stratification, keeping of records of the most serious cases of users in psychological distress, and provision of group care. The items that required a higher level of mental health care in the parameter of location were the provision of any type of group care and the provision of educational and mental health promotion activities. Total Cronbach’s alpha coefficient was 0.87. The items that obtained the highest correlation with total score were the recording of the most serious cases of users in psychological distress and scheduling of the agenda according to risk stratification. The final scores obtained oscillated between -2.07 (minimum) and 1.95 (maximum). CONCLUSIONS: There are important aspects in the discrimination of the capacity to provide mental health care by primary health care teams: risk stratification for care management, follow-up of the most serious cases, group care, and preventive and health promotion actions.OBJETIVO: Determinar os itens do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica que melhor avaliam a capacidade de oferta de cuidados em saúde mental. MÉTODOS: Estudo transversal efetuado por meio do Modelo de Resposta Gradual da Teoria da Resposta ao Item, utilizando dados secundários do segundo ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica, tendo sido avaliadas 30.523 equipes de atenção básica no período de 2013 a 2014. A consistência interna, a correlação entre os itens e dos itens com o escore total foram testadas usando os coeficientes alfa de Cronbach, correlação de Spearman e ponto bisserial, respectivamente. Foram testados os pressupostos de unidimensionalidade e independência local dos itens. Utilizaram-se como uma das formas de apresentação dos resultados as nuvens de palavras. RESULTADOS: Programar a agenda de acordo com a estratificação de risco, manter registro dos casos mais graves de usuários em sofrimento psíquico e ofertar algum atendimento em grupo foram os itens com maior capacidade de discriminação. Ofertar alguma modalidade de atendimento em grupo e ofertar ações educativas e de promoção de saúde mental foram os itens que requereram maior nível de oferta de cuidados em saúde mental no parâmetro de locação. O coeficiente alfa de Cronbach total foi 0,87. Realizar o registro dos casos mais graves de usuários em sofrimento psíquico e programar a agenda de acordo com a estratificação de risco foram os itens que obtiveram maior correlação com o escore total. Os escores finais obtidos oscilaram entre -2,07 (mínimo) e 1,95 (máximo). CONCLUSÕES: São aspectos relevantes na discriminação da capacidade de ofertar cuidados em saúde mental pelas equipes de atenção básica: a estratificação do risco para gestão do cuidado, o acompanhamento dos casos mais graves, o atendimento em grupo e as ações preventivas e de promoção da saúde

    OBJECTIVE: To associate the strength of community health workers interventions with primary health care strategies for women’s and children’s health, diabetes, and hypertension. METHODS: This is a cross-sectional study assessing 29,778 family health teams working in primary health care in Brazil in 2014. The association between community health workers activity levels and primary health care facilities was analyzed using multiple logistic regression. RESULTS: We found higher levels of community health workers activities strongly associated with primary health care practices (OR = 6.88) for those activities targeting hypertension management, followed by children’s health (OR = 6.56), and women’s health (OR = 6.21). CONCLUSIONS: At a time when Brazil discusses whether community health workers should or should not remain in the same scale-up and skill level as they currently are, our results reinforce the importance of these workers for the care model advocated by the Brazilian Unified Health System

    http://dx.doi.org/10.5902/2179460X16145The replacement of natural forests to monoculture can cause changes in local and regional climate due to changes in net radiation and energy exchanges between the surface and the atmosphere. Thus, the objective of this study was to evaluate changes in biophysical indices such as Normalized Difference Vegetation Index (NDVI), albedo, temperature and net radiation of the surface due to the change of land cover in native Cerrado area in Campo Novo do Parecis, Mato Grosso State. We obtained Landsat 5 TM images to calculate the biophysical indices in protected and deforested areas. The NDVI of the protected area was 72% higher, the surface albedo was 56.1% lower and the surface temperature was 39.2% lower than in the deforested area. Thus, the balance of daily radiation in the protected was 6.6% higher than in the deforested area, which showed that conversion of native Cerrado area modifies the net radiation exchange between the surface and the atmosphere.A substituição de florestas naturais para o cultivo de monoculturas pode provocar alterações no clima local e regional devido às mudanças nas trocas líquidas de radiação e energia entre a superfície e a atmosfera. Neste sentido, o objetivo deste trabalho foi avaliar mudanças em índices biofísicos como o Normalized Difference Vegetation Index (NDVI), albedo da superfície, temperatura da superfície e saldo de radiação da superfície devido à alteração da cobertura do solo em área nativa de Cerrado em Campo Novo do Parecis, Mato Grosso. Para tanto foram obtidas imagens TM Landsat 5 para calcular os índices biofísicos de uma área com reserva legal e área desmatada de Cerrado. O NDVI da área de reserva legal foi 72% maior, o albedo da superfície 56,1% menor, a temperatura da superfície 39,2% menor que na área desmatada. Dessa forma, o saldo de radiação diário na área de reserva legal foi 6,6% maior que na área desmatada, demonstrando que a conversão da área nativa de Cerrado modifica as trocas líquidas de radiação entre a superfície e a atmosfera

    A emergência de uma nova pandemia não é uma questão de “se”, mas de “quando” irá acontecer. Atualmente, estamos diante da mais importante crise de saúde pública mundial, a pandemia do novo coronavírus. A Universidade é uma instituição criada para atender às necessidades sociais e uma das estratégias para realizar esse dever é através de ações de extensão universitária. Mas como realizar extensão universitária frente ao isolamento social imposto pelo COVID-19? Durante a pandemia a Universidade ganhou destaque em ações extensionistas, especialmente na disseminação e construção correta do conhecimento sobre SARS-CoV-2 e COVID-19, em ações que objetivam o desenvolvimento e confecção de insumos para proteção individual e coletiva, distribuídos para hospitais, profissionais de saúde e em comunidades carentes, e atividades de educação e cultura explorando novos recursos em plataformas digitais. Acreditamos no poder transformador da Universidade e no seu compromisso em reduzir impactos sociais através da extensão e que no futuro próximo a extensão deve ser enquadrada no mundo pós-pandemia

    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

    AimAmazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types.LocationAmazonia.TaxonAngiosperms (Magnoliids; Monocots; Eudicots).MethodsData for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny.ResultsIn the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2 = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2 = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.Main ConclusionNumerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions
