Risco de COVID-19 em profissionais de saúde da linha de frente e intervenções: revisão sistemática
Objective: to identify the evidence related to the risks of SARS-CoV-2 exposure in healthcare workers and the interventions adopted. Method: systematic literature review in eight scientific databases and three gray literature repositories. Results: 26 studies identified as risk factors: scarcity, inadequate use or reuse of personal equipment; low adherence to precautionary measures; working in intensive care and COVID-19 sectors; long stay in a closed work environment; sharing eating areas without the use of masks and distance; low knowledge and unpreparedness for disease management. 12 studies identified as interventions: health surveillance programs with early detection, diagnosis and early withdrawal; organization of care flows; double triage; telemedicine; limitation of visits; creation of exclusive sectors for care to COVID-19; qualification and training with virtual tools and simulation. Conclusion: besides the risk of infection, individual, psychosocial and organizational factors made the healthcare work environment unsafe. Interventions should be adopted to mitigate the risks and decrease the professionals' morbidity and mortality.Objetivo: identificar as evidências relacionadas aos riscos de exposição ao SARS-CoV-2 em profissionais de saúde e as intervenções adotadas.

Colicistite aguda alitiásica condutas que reduzem a taxa de internação em Terapia de Unidade Intensiva: uma revisão sistemática: Acute althiasic cholicistitis conducts that reduce the hospitalization rate in Intensive Unit Therapy: a systematic review
Os cálculos biliares se encontram em mais de 10% da população mundial, sendo que esta incidência se torna maior com o avanço da idade. Sendo assim a colecistite pode ser considerada como uma emergência comum no mundo, sendo que na maior parte dos casos é decorrente da inflamação da parede interna da vesícula devido á impactação do cálculo e decorrente obstrução no ducto cístico, produzindo assim dor repentina e aguda, entretanto a colecistite aguda alitiásica ocorre sem que haja cálculos em seu interior. Esse trabalho possui como sua pergunta de pesquisa qual conduta deve ser adotada para reduzir a taxa de internação em UTI’s em pacientes que apresentem colicistite aguda alitiásica. E assim como seu objetivo geral demonstrar a conduta adequada para manejo de pacientes que apresentem colicistite aguda alitiásica. E como seus objetivos específicos: Identificar do que se trata um quadro de colicistite aguda alitiásica; Auxiliar na tomada de conduta pelos profissionais acerca do tratamento adequado; Disponibilizar informações acerca do assunto. Esse trabalho trata-se de uma revisão sistemática de artigos extraídos das plataformas do PubMed, BVS, Lilacs, Medline, Scielo, esses que possuem datas dos últimos 5 anos e escritos nos seguintes idiomas: português, inglês e espanhol. Com isso conclui-se que ainda são escassos os estudos acerca do tema, portanto é necessário que os médicos consigam de forma significativa o diagnóstico com agilidade, e para isso o conhecimento sobre assunto por uma equipe multidisciplinar deve ser amplamente desenvolvido
Pervasive gaps in Amazonian ecological research
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

Bragança-Marituba for the research support.Tropical forests face increasing climate risk1,2, yet our ability to predict their response to climate change is limited by poor understanding of their resistance to water stress. Although xylem embolism resistance thresholds (for example, Ψ50) and hydraulic safety margins (for example, HSM50) are important predictors of drought-induced mortality risk3-5, little is known about how these vary across Earth's largest tropical forest. Here, we present a pan-Amazon, fully standardized hydraulic traits dataset and use it to assess regional variation in drought sensitivity and hydraulic trait ability to predict species distributions and long-term forest biomass accumulation. Parameters Ψ50 and HSM50 vary markedly across the Amazon and are related to average long-term rainfall characteristics. Both Ψ50 and HSM50 influence the biogeographical distribution of Amazon tree species. However, HSM50 was the only significant predictor of observed decadal-scale changes in forest biomass. Old-growth forests with wide HSM50 are gaining more biomass than are low HSM50 forests. We propose that this may be associated with a growth-mortality trade-off whereby trees in forests consisting of fast-growing species take greater hydraulic risks and face greater mortality risk. Moreover, in regions of more pronounced climatic change, we find evidence that forests are losing biomass, suggesting that species in these regions may be operating beyond their hydraulic limits. Continued climate change is likely to further reduce HSM50 in the Amazon6,7, with strong implications for the Amazon carbon sink.Publisher PDFPeer reviewe
Mapping density, diversity and species-richness of the Amazon tree flora
Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution
Geography and ecology shape the phylogenetic composition of Amazonian tree communities
Aim: Amazonia 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.
Location: Amazonia.
Taxon: Angiosperms (Magnoliids; Monocots; Eudicots).
Methods: Data 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\u27s 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.
Results: In 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 (R = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.
Main Conclusion: Numerous 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
