    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.

    Análise de contexto de acordo com o referencial proposto por Hinds, Chaves e Cypress, operacionalizada por uma revisão de escopo, cujo o objetivo é Analisar os contextos que influenciam a adesão ao tratamento farmacológico após a alta hospitalar de pacientes em fase de pós-transplante de células-tronco hematopoéticas

    Neurotoxicidades apresentadas por pacientes submetidos ao transplante de células-tronco hematopoéticas: scoping review

    No full text
    O Transplante de Células-Tronco Hematopoéticas (TCTH) é utilizado como estratégia de tratamento para uma séria de agravos malignos e não malignos herdados ou adquiridos. Consiste na infusão endovenosa de Células-Tronco Hematopoéticas (CTH) provenientes da medula óssea, sangue periférico ou sangue de cordão umbilical e placentário, com o objetivo de restabelecer a função medular e/ou imunológica dos pacientes com indicação para este procedimento, com possibilidade cura ou aumento da sobrevida. Existem três formas distintas de TCTH, o transplante autólogo, no qual o paciente é o seu próprio doador, o alogênico, quando as CTH são provenientes de doador com antígeno leucocitário humano compatível, aparentado ou não, e singênico, quando o doador é um irmão gêmeo idêntico. O TCTH é utilizado com sucesso, porém, por se tratar de um procedimento agressivo, são detectados índices de morbidade e mortalidade associados ao tratamento em suas diferentes fases, a exemplo das neurotoxicidades, que podem ocorrer, especialmente, no pré e pós-transplante. Portanto, justifica-se a necessidade de realização desta pesquisa, a fim de mapear as evidências sobre as neurotoxicidades apresentadas por pacientes submetidos ao TCTH e contribuir para a construção de conhecimentos que forneçam elementos para melhor planejamento e promoção das ações oferecidas nos serviços de atenção a estes pacientes específicos
