    A morte decorrente do trauma Ă© um grande problema de saĂșde no mundo inteiro, resultando em quase 14 mil mortes diariamente, o trauma se evidencia entre as cinco principais causas de morte. Nos Ășltimos 10 anos, mais de 1 milhĂŁo de pessoas ficaram invĂĄlidas devido a traumas mecĂąnicos no Brasil, sendo os acidentes de trĂąnsito os principais responsĂĄveis por estas taxas. AlĂ©m do aumento do nĂșmero de veĂ­culos em circulação, a desorganização, a deficiĂȘncia geral da fiscalização, as pĂ©ssimas condiçÔes de muitos veĂ­culos, o comportamento dos usuĂĄrios e a impunidade dos infratores fizeram com que nas Ășltimas dĂ©cadas o Brasil se colocasse entre os campeĂ”es mundiais de acidentes de trĂąnsito. As lesĂ”es cerebrais constituem uma causa importante de morte, especialmente em adultos jovens, e uma causa importante de incapacidade. Atualmente estĂŁo cada vez mais disseminados os agentes causais de lesĂ”es nos seres humanos, tais como: os meios de transportes, o maquinĂĄrio agrĂ­cola e industrial, o aumento da agressividade das armas de fogo, entre outros. Se por um lado o aumento tecnolĂłgico tem contribuĂ­do para o aumento da qualidade de vida, por outro ameaça a sobrevivĂȘncia dos cidadĂŁos. Esta pesquisa se enquadra como revisĂŁo de literatura, do tipo sistemĂĄtica de carĂĄter exploratĂłrio e abordagem qualitativa. O grande objetivo desta pesquisa foi elaborar atualização acerca das informaçÔes acerca do trauma cranioencefĂĄlico de forma a fomentar atualização em saĂșde

    Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

    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

We integrate ecological community metadata of 7,694 sampling sites for multiple organism 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 neglected areas in ecological research are expected to experience severe climate or land use changes by 2050.

    COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

    Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≀ 18 years: 69, 48, 23; 85%), older adults (≄ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

    Relata a presença abusiva do consumo de ĂĄlcool por crianças e adolescentesem nossa sociedade. Tal pratica torna a população vulnerĂĄvel aos riscos que comprometem a saĂșde e a convivĂȘncia social. O alcoolismo Ă© considerado um problema de saĂșde pĂșblica. As Leis n. 9.294/96 e 8.069/90, proĂ­bem a venda de bebidas alcoĂłlica a menor de dezoito anos, como forma de prevenir os jovens das consequĂȘncias advindas desse tipo de entorpecente. Os Ă­ndices mostram que a acessibilidade dos jovens ao ĂĄlcool ocorre de maneira frequente. Percebe-se que crianças e adolescentes fazem uso de bebidas alcoĂłlicas com frequĂȘncia, comprometendo dessa forma seu desenvolvimento psicossocial. A pesquisa tem como objetivo geral compreender as formas de combate ao alcoolismo precoce, buscando entender o conceito de alcoolismo, alĂ©m de analisar os principais levantamentos epidemiolĂłgicos atravĂ©s da legislação voltada para jovens eavaliar como Ă© possĂ­vel advertir os jovens do uso de ĂĄlcool precocemente. Desta forma, concluiu-se que as polĂ­ticas pĂșblicas podem investir em açÔes que busquem a prevenção do uso do ĂĄlcool por crianças e adolescentes. Neste sentido, a prevenção do uso do ĂĄlcool na adolescĂȘncia serĂĄ um instrumento que poderĂĄ ser usado para a sociedade refletir buscando uma maior efetividade em prol do combate ao alcoolismo
