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.

Experimental investigation of the performance of cementitious mixtures with lignocellulosic residue as a partial cement replacement

The construction industry, one of the most important productive and economic activities, is also responsible for environmental impacts like the extraction of raw materials, generation of waste and cement manufacturing, among others. The main objective was to study the technical feasibility of applying the residue generated by the second-generation ethanol obtained from sugarcane to partially replace the cement in concrete mixtures. The residue has lignin in its composition and was applied without further industrial processing. In addition, the research sought to obtain answers regarding the performance of these compositions in relation to the workability in the fresh state and the compressive strength and durability in the hardened state and compared the possible behavior differences between the residues with and without the presence of superplasticizer and plasticizers, both chemical admixtures. The results showed that there was compatibility between the residues and chemical admixtures; the setting time and the consistency index increased with the application of the residues; the compressive strength with residues was lower than the reference composition, but still demonstrated feasibility; in all the tests carried out the durability improved in the residue compositions. Thus, the results were very promising and pointed to major developments.O setor da construção civil nos últimos anos vem causando significativos impactos no meio ambiente pela extração de matéria prima e produção de cimento, entre outros. Esta pesquisa visa analisar a viabilidade técnica da substituição parcial do cimento pelo resíduo do bioetanol celulósico, ou etanol de segunda geração em argamassas de concreto, sem que o resíduo passe por outros processos industriais. O resíduo foi estudado de duas formas: seco em estufa e destorroado (Rseco), e queimado em um forno para a obtenção de cinzas (Rcinza). Foram estudadas doze composições diferentes ajustando a substituição parcial dos diferentes resíduos e a incorporação de aditivos químicos superplastificante (SP) e plastificante (P). No estado fresco, foram realizados ensaios de tempo de pega com a agulha de Vicat e determinação do índice de consistência através de mesa vibratória. Já no estado endurecido, ensaios de resistência à compressão e de durabilidade, sendo estes: absorção de água por capilaridade, ascensão capilar e índice de vazios. Com base nos resultados, verificouse que: houve a compatibilidade de utilização do resíduo com os aditivos químicos SP + P; a presença do resíduo Rseco foi suficiente para retardar o tempo de início e fim de pega, mesmo sem o uso de aditivos químicos retardadores; a incorporação do resíduo não afetou a trabalhabilidade da mistura; houve uma diminuição da resistência à compressão nas composições com resíduo, mas esta não interferiu na viabilidade; e a utilização do resíduo provocou melhores resultados de durabilidade em todos os testes realizados. Por fim, os resultados mostraram que houve viabilidade técnica para a aplicação dos resíduos estudados, incentivando a continuidade da pesquisa com o uso de novas composições, novas porcentagens, testes e variáveis de análise

Drug therapy and vascular devices used by patients hospitalized for COVID-19: a descriptive study / Terapia medicamentosa e dispositivos vasculares utilizados por doentes hospitalizados para a COVID-19: um estudo descritivo

To describe drug therapy and types of vascular access adopted in the treatment of patients with COVID-19 and admitted to the clinical wards of a university hospital, a referential institution for COVID-19 in Rio de Janeiro, Brazil. Descriptive, retrospective documentary study with a quantitative approach. The sample consisted of 243 electronic medical records from hospitalized patients with a laboratory-confirmed diagnosis of COVID-19, between April and June 2020. The selection of participants took place by intentional non-probabilistic sampling. Peripheral venous access was the mostly applied in 83.5% of the patients. The mostly used classes of drugs were analgesics, (81.9%), followed by antiemetics (70.4%), and antihypertensives (51.9%). For medications directed to COVID-19, azithromycin, oseltamivir, ceftriaxone, and hydroxychloroquine stands out with 67.5%, 58.8%, 50.2% and 27.2%, respectively.  Regarding the treatment directed to COVID-19, the medications mostly taken were azithromycin and hydroxychloroquine, justified to a large extent by being recommended by the Ministry of Health in the treatment, according to signs and symptoms (Brazil, 2020).  Patients treated with the medications described had good recovery from the clinical condition. Thus, studies based on randomized clinical trials are suggested to prove the efficacy of drug therapies, including their combination

Inibidores de Janus quinase (JAK) como agentes terapêuticos para Artrite Reumatoide: eficácia e segurança

A artrite reumatoide (AR) é uma doença autoimune crônica que afeta principalmente as articulações, resultando em inflamação, dor e danos progressivos nas estruturas articulares, resultando em inflamação, dor e danos progressivos. O tratamento da artrite reumatoide (AR) tem sido uma área de constante evolução, com o objetivo de controlar os sintomas, prevenir danos articulares e melhorar a qualidade de vida dos pacientes. Nos últimos anos, os inibidores de Janus Quinase (JAK) surgiram como uma classe promissora de medicamentos no arsenal terapêutico disponível. Nesse sentido, o presente estudo tem como objetivo analisar a eficácia e segurança do tratamento da artrite reumatoide com inibidores de JAK (JAKi). Para isso, foram selecionados três artigos que avaliaram o uso dos JAKi, publicados entre 2013 a 2023, nas bases de dados PubMed (Medline), Scientific Electronic Library Online (SciELO) e Cochrane Library. Observaram-se resultados com melhora estatisticamente significativa na obtenção de respostas ACR20, ACR50 e ACR70 com o baricitinibe em comparação com o placebo (p < 0,05). As razões de chances (odds ratio) calculadas, juntamente com os intervalos de confiança de 95% correspondentes, corroboraram esses achados, com razões de chances de 2,50 (IC 95%: 1,80-3,47) para ACR20, 2,12 (IC 95%: 1,47-3,06) para ACR50 e 1,78 (IC 95%: 1,23-2,57) para ACR70. Ademais, observou-se segurança ao adicionar os JAKi à terapia combinada com o metotrexato para o tratamento da AR, sem aumento do risco de malignidade. Em suma, os inibidores de JAK são eficazes no tratamento da artrite reumatoide, ao proporcionarem melhorias significativas nos sintomas e nas respostas clínicas dos pacientes. Além disso, apresentaram um perfil de segurança favorável, com uma incidência semelhante de eventos adversos graves em comparação com o placebo. Esses resultados sugerem que o baricitinibe pode ser uma opção terapêutica viável para o manejo da artrite reumatoide. No entanto, são necessários estudos adicionais para avaliar a eficácia e segurança em diferentes populações de pacientes, bem como para investigar o perfil de segurança a longo prazo

Clinical nursing care protocol for convalescent plasma transfusion in patients with COVID-19

Introduction: The treatment of COVID-19 is still challenge. So convalescent plasma can be an important alternative of treatment. Protocols with nursing care during infusion is very important to guide an effective and safety care Objective: to analyze the evidence in the literature on the action of convalescent plasma, of the use of protocols with nursing care to use convalescent plasma and build a nursing care protocol for transfusion in patients with COVID-19. Methods: Methodological study carried out in two stages: scoping review. The search was done using the descriptors: convalescent plasma transfusion, convalescent plasma, and acute respiratory syndromes or COVID-19, to found protocols and effectiveness of convalescent plasm. Beside was done a specialist panel to build the protocol. Results: Low-evidence studies have shown improvement in the clinical signs of COVID-19 using Convalescent Plasma, reduction or elimination of viral load, benefits in the production of lymphocytes, decreases C-reactive protein, increases titers of anti-SARS-CoV-2 antibodies, positive evolution in lung involvement identified by X-rays, decrease in hospitalization. No studies were found in the databases on the protocol for clinical nursing care in plasma transfusion. Therefore, a protocol was developed with the description of clinical nursing care to be performed before, during and after the transfusion by plasma: checking of vital signs and indicative signs of transfusion reaction, measurement of oxygen saturation, assessment of venous access and checking of the level of consciousness. Conclusion: There are no evidence studies to support the use of plasma, nor anything related to bundles
