BACKGROUND In Brazil, transmission of visceral and cutaneous leishmaniasis has expanded geographically over the last decades, with both clinical forms occurring simultaneously in the same area. OBJECTIVES This study characterised the clinical, spatial, and temporal distribution, and performed entomological surveillance and natural infection analysis of a leishmaniasis-endemic area. METHODS In order to characterise the risk of leishmaniasis transmission in Altos, Piauí, we described the clinical and socio-demographic variables and the spatial and temporal distribution of cases of American visceral leishmaniasis (AVL) and American cutaneous leishmaniasis (ACL) cases and identified potential phlebotomine vectors. FINDINGS The urban area concentrated almost 54% of ACL and 86.8% of AVL cases. The temporal and spatial distribution of AVL and ACL cases in Altos show a reduction in the number of risk areas, but the presence of permanent disease transmission foci is observed especially in the urban area. 3,808 phlebotomine specimens were captured, with Lutzomyia longipalpis as the most frequent species (98.45%). Of the 35 females assessed for natural infection, one specimen of Lu. longipalpis tested positive for the presence of Leishmania infantum and Leishmania braziliensis DNA. MAIN CONCLUSION Our results indicate the presence of risk areas for ACL and AVL in the municipality of Altos and highlight the importance of entomological surveillance to further understand a possible role of Lu. longipalpis in ACL transmission.

RESUMO Landoltia punctata é uma espécie de lentilha-d’água originária da Índia, mas que atualmente tem registro em todos os continentes, à exceção da Antártida. A espécie tem interesse econômico, sendo usada em fitorremediação, mas principalmente por seu grande potencial invasor biológico. Aqui reportamos o primeiro registro dessa espécie para a região Amazônica, ampliando sua distribuição conhecida e chamar a atenção para a potencial perda da biodiversidade no tipo de ambiente em que a espécie foi registrada. Estudos futuros deveriam focar no potencial competitivo e controle populacional de L. punctata na região. lentilhadágua lentilha d água Índia continentes Antártida econômico fitorremediação biológico Amazônica registrada L

ABSTRACT Landoltia punctata is a species of duckweed originating from India, but has been recorded in all continents, except Antarctica. It is of economic interest, being used in phytoremediation, but mainly due to its high invasive potential. Here we report the first record of this species in the Amazon region, both expanding its known distribution and raising awareness about the potential losses of biodiversity that may occur in the kind of environment where the species was registered. Future studies should focus on the competitive potential and population control of L. punctata in the region. India continents Antarctica interest phytoremediation region registered L

Purpose This study aims to explore the interplay between market concentration and implicit tax burdens in Brazil, offering a fresh perspective on the conventional belief of perfect competition. Design/methodology/approach Data was sourced from Brazilian firms on the B3 stock exchange between 2011 and 2021. Multiple linear regression techniques were employed to analyze the relation of explicit tax rates to firms’ pre- and post-tax returns. Findings Dominant firms in the market tend to bear a lower implicit tax burden and have the capacity to extend tax incentive benefits to shareholders. Research limitations/implications The findings highlight Brazil’s intricate corporate tax fabric, particularly regarding implicit taxes. They provide a foundation for deeper inquiries into how market dominance, taxation policies, and corporate strategies converge. Practical implications Regulators and business leaders can harness this knowledge to recalibrate tax strategies and market regulations. Specifically, a closer examination of the dynamics that permit reduced implicit tax implications in monopolized markets is essential for equity. Social implications Companies with pronounced market concentration can mitigate their implicit tax burdens, potentially offloading them to consumers and suppliers. This points to potential inequities in current tax structures. Originality/value This research unveils nuanced insights into Brazil’s multifaceted interrelations between corporate influence, taxation strategies, and market forces.

RESUMO A salinidade pode promover efeitos danosos ao desenvolvimento vegetal, sendo o necessário o uso de estratégias para minimizar os danos promovidos, como a manutenção equilibrada do estado nutricional da planta. Assim, o objetivo deste estudo foi avaliar o efeito da adubação nitrogenada foliar e da salinidade no crescimento e eficiência fotoquímica de manjericão roxo. O experimento foi conduzido com o delineamento de blocos casualizados, em arranjo fatorial incompleto 5 × 5 (salinidades da água de irrigação: 0,5; 0,81; 2,75; 4,69 e 5,50 dS m-1 × doses de nitrogênio: 0; 58,58; 200; 341,42 e 400 mg L-1), gerados através da matriz experimental Composto Central de Box. O aumento da salinidade da água de irrigação reduz o crescimento e a eficiência fotoquímica das plantas de manjericão roxo. Todavia, a aplicação foliar de 400 mg L-1 de N atenuou os efeitos deletérios da salinidade sobre as taxas de crescimento absoluto e relativo para o diâmetro do caule e relativo para a altura de plantas, assim como na fluorescência da clorofila a. Esses resultados mostram que a adubação foliar nitrogenada é uma estratégia para mitigar o estresse salino em plantas de manjericão. vegetal promovidos planta Assim roxo casualizados salinidades 0,5 05 0 0,81 081 81 2,75 275 2 75 469 4 69 4,6 550 50 5,5 m1 m 1 m- nitrogênio 58,58 5858 58 200 34142 341 42 341,4 40 L1, L1 L , L-1) Box Todavia L- 0, 0,8 08 8 2,7 27 7 46 6 4, 55 5, 58,5 585 20 3414 34 341, 2, 58, 3

ABSTRACT Salinity can have detrimental effects on plant development. To minimize this damage, strategies such as balanced maintenance of plants’ nutritional status have been proposed previously. The objective of this study is to investigate whether the optimization of foliar nitrogen fertilization can promote the growth and photochemical efficiency of purple basil subjected to salt stress. The experiment was performed using a randomized block design with an incomplete 5 × 5 factorial arrangement generated through experimental matrix Central Composite Design with two parameters: salinity of irrigation water at 0.5, 0.81, 2.75, 4.69, and 5.50 dS m-1; and nitrogen doses at 0, 58.58, 200, 341.42, and 400 mg L-1. It was found that an increase in the salinity of irrigation water reduced the growth and photochemical efficiency of purple basil. However, the foliar application of nitrogen at the concentration of 400 mg L-1 attenuated the harmful effects of salinity on both the absolute and relative growth rates of stem diameter, the relative growth of plant height, and chlorophyll A fluorescence. These results showed that foliar nitrogen fertilization is a suitable strategy to help mitigate salt stress in basil plants. development damage plants previously parameters 05 0 0.5 081 81 0.81 275 2 75 2.75 469 4 69 4.69 550 50 5.5 m1 m 1 m-1 5858 58 58.58 200 34142 341 42 341.42 40 L1.

Resumo O uso desordenado dos recursos hídricos tem levado ao esgotamento, resultando no surgimento de questões ambientais e sociais. Um aspecto relevante a ser observado nos sistemas de abastecimento de água são as perdas físicas que ocorrem durante todo o processo operacional do sistema. Muitos pacotes de software diferentes permitem simulações de pressões e fluxos em redes de água. O mais utilizado é o EPANET. O epanet2toolkit é um pacote R recentemente desenvolvido que realiza a interação entre EPANET e R. Com base nesta ferramenta, são desenvolvidos um conjunto de funções para estudar e avaliar uma rede teórica. O objetivo é encontrar uma configuração de rede ideal (projeto) principalmente para gerenciamento de pressão que reduza simultaneamente as perdas físicas. Os elementos da rede hídrica, como rugosidade, níveis dos reservatórios e diâmetros são utilizados como parâmetros. Uma simulação de Monte Carlo é gerada, com base em valores aleatórios dos parâmetros desta rede. A partir destes, é encontrado um cenário de pressão ideal, resultando em uma redução de 11,6% na ocorrência de perdas físicas em relação ao caso base. esgotamento sociais sistema epanettoolkit epanet toolkit ferramenta teórica projeto (projeto hídrica rugosidade gerada destes 116 11 6 11,6 1 11,

Many different software packages allow simulations of pressures and flow in water networks. The most used is EPANET. The epanet2toolkit is a recently developed R package that performs the interaction between EPANET and R. Based on this tool, a set of functions is developed to study and evaluate a theoretical network. The objective is to find an ideal network configuration (design) mainly for pressure management which simultaneously reduces physical losses. Water network parameters, such as roughness, reservoir levels, and diameters are used as parameters. A Monte Carlo simulation is generated, based on random values of these network parameters. From these, an ideal pressure scenario is found, resulting in a reduction of 11.6% in the occurrence of physical losses concerning the base case. depletion issues system s process networks epanettoolkit epanet toolkit tool design (design parameters roughness levels generated found 116 11 6 11.6 case 1 11.

ABSTRACT Objective Published studies have shown associations between anti-ribosomal P (anti-P) antibody and systemic lupus erythematosus with hepatic manifestations. This has been reported also in autoimmune hepatitis. However, the consistency of the latter association remains controversial. This study aimed to evaluate the frequency of anti-P antibodies in autoimmune hepatitis using two different immunoassays. Methods One-hundred and seventy-seven patients with autoimmune hepatitis were screened, and 142 were analyzed for anti-P antibody positivity. The samples were first analyzed using two different immunoassays: enzyme-linked immunosorbent assay (ELISA) and chemiluminescence and then compared with a group of 60 patients with systemic lupus erythematous. The positive samples were subjected to western blot analysis. Results Anti-P was found in 5/142 autoimmune hepatitis cases (3.5%) by chemiluminescence and in none by ELISA. Among the five chemiluminescence-positive autoimmune hepatitis samples, on anti-P western blot analysis one was negative, two were weakly positive, and two were positive. In contrast, anti-P was detected in 10/60 patients with systemic lupus erythematosus (16.7%) and presented higher chemiluminescence units than the autoimmune hepatitis samples. Conclusion A low frequency of anti-P antibodies was observed in autoimmune hepatitis, suggesting that this test is not useful for the diagnosis or management of this disease. antiribosomal anti ribosomal antiP (anti-P manifestations However controversial immunoassays Onehundred One hundred seventyseven seventy seven screened 14 positivity enzymelinked enzyme linked ELISA (ELISA 6 erythematous AntiP Anti 5142 5 5/14 3.5% 35 3 (3.5% chemiluminescencepositive negative contrast 1060 10 10/6 16.7% 167 16 7 (16.7% disease 1 514 5/1 3.5 (3.5 106 10/ 16.7 (16.7 51 5/ 3.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.

Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

RESUMO Em regiões com limitações de recursos hídricos o uso eficiente da água torna-se a cada dia imprescindível para a produção agrícola. Objetivou-se com o presente trabalho avaliar o uso da bagana de carnaúba como opção de cobertura vegetal para a redução do uso da água no cultivo do rabanete irrigado. A pesquisa foi conduzida no período de julho a outubro de 2018 em dois ciclos de produção no município de Pentecoste-CE. O experimento foi em blocos ao acaso com parcelas subdivididas e constituído de quatro repetições, sendo os tratamentos primários constituídos por cinco lâminas de irrigação (50%; 75%; 100%; 125% e 150% da evapotranspiração da cultura localizada) e os tratamentos secundários constituídos por cinco níveis de cobertura vegetal, constituída de bagana de carnaúba (0%; 25%; 50%; 75% e 100% de 16 t ha-1), em uma interação 5 x 5, totalizando 100 parcelas experimentais. Foram avaliadas as variáveis massa fresca da parte aérea e túbera, altura de plantas, número de folhas, diâmetro da túbera e trocas gasosas. Para a variável massa fresca da túbera no primeiro ciclo de produção, com a superfície de resposta, obteve -se um modelo de primeira ordem com aumento linear dos fatores lâminas de irrigação (0,064 g planta-1) e cobertura vegetal (0,065 g planta-1), sendo o maior valor (40,44 g planta-1) observado para o nível de 150% de ETcloc e 100% de bagana. A aplicação de 16 t ha-1 de bagana de carnaúba pode ser considerada recomendável, dentro dos limites estudados, para uso na cultura do rabanete.

ABSTRACT In regions with limited water resources, efficient use of water has become increasingly essential for agricultural production. The objective of the present study was to evaluate the use of the carnauba palm bagana (leaf fibers) as an option of ground cover to reduce the use of water in irrigated radish. The study was conducted from July to October 2018 in two crop cycles in Pentecoste-CE, Brazil. The experiment was carried out in randomized blocks with split plots and four replicates, whose primary treatments consisted of five irrigation depths (50%; 75%; 100%; 125% and 150% of the evapotranspiration crop) and secondary treatments consisted of five different levels of ground cover using carnauba bagana (0%; 25%; 50%; 75% and 100% of 16 t ha-1), in a 5 x 5 interaction, totaling 100 experimental plots. The following variables were evaluated: fresh mass of shoots and tuber, plant height, number of leaves, tuber diameter and gas exchange. For tuber fresh mass in the first crop cycle, a first order model was obtained with the response surface, with linear increase of the factors irrigation depths (0.064 g plant-1) and ground cover (0.065 g plant-1), with the highest value (40.44 g plant-1) observed for the level of 150% ETcloc and 100% bagana. Application of 16 t ha-1 of carnauba bagana can be considered recommended, within the limits studied, for use in the radish crop.

RESUMO O objetivo desta revisão foi comparar dois modelos de agricultura sustentáveis, demostrando as vantagens e desvantagens de ambos, correlacionando-os entre si. As diversas práticas agrícolas contemporâneas compreendem modelos alternativos de agricultura, como permacultura, agricultura biológica, orgânica, biodinâmica, que são consideradas sustentáveis, e modelos intensivos de produção, que apresentam vários pontos negativos, contrastando com os modelos alternativos. A busca por uma agricultura menos agressiva ao meio ambiente, que permaneça produtiva em longo prazo, tem sido uma preocupação constante de pesquisadores e produtores. Os modelos de agricultura assemelham-se entre si, o que os difere são apenas algumas práticas que não são permitidas em todos, e suas bases de fundamentação. Nesta revisão dois modelos foram mais abordados de forma simplificada, para a percepção dos seus conceitos e de suas bases fundamentais, mostrando o que os diferencia, e que mesmo assim os leva para um mesmo objetivo, criar um ecossistema independente de recursos externos.

ABSTRACT The objective of this review was to compare two models of sustainable agriculture, demonstrating their advantages and disadvantages and correlating them with each other. The diverse contemporary agricultural practices comprise from alternative models of agriculture, such as permaculture, organic farming, organic, biodynamic, that are considered sustainable, and intensive production models, that present several negative points, contrasting with alternative models. The search for a less aggressive agriculture to the environment, what stay productive in the long run, it has been a constant concern of researchers and producers. Agricultural models are similar to each other, what differs are some practices that do not are allowed in all, and its foundation bases. In this review, two models were more approached in a simplified way, to the perception of their concepts and fundamental bases, showing what differentiates them, and that still leads to the same goal, creating an ecosystem independent of external resources.

ABSTRACT Aedes aegypti is associated with epidemic diseases in Brazil, such as urban yellow fever, dengue, and more recently, chikungunya and Zika viruses infections. More information about Ae. aegypti infestation is fundamental to virological surveillance in order to ensure the effectiveness of control measures in use. Thus, the present study aims to identify and compare infestation and infectivity of Ae. aegypti females in Macapa city, Amapa State (Amazon region), Brazil, between the epidemiological weeks 2017/02 and 2018/20. A total number of 303 Ae. aegypti females were collected at 21 fixed collection points, 171 at the 10 collection points in the Marabaixo neighborhood and 132 at the 11 collection points in the Central neighborhood. Among the collected samples, only two were positive for dengue virus, with a 2.08% (2/96 pools) infectivity rate for Marabaixo. The difference between the medians of Ae. aegypti females captured in Central and Marabaixo sites was not statistically significant. The findings indicate similar mosquito infestation levels between the neighborhoods, and a low-level of mosquito infectivity, although dengue virus was found only in Marabaixo. Virological surveillance of Ae. aegypti was important to identify sites of infection and determine possible routes of transmission to enable health surveillance teams to adopt preventive strategies where infected mosquitoes are present and act faster.

RESUMO: O objetivo deste estudo foi avaliar as alterações hematológicas, bioquímicas e hemogasométricas do sangue total de caprinos armazenado em diferentes bolsas de sangue. Foram utilizados sete caprinos machos, adultos, sem raça definida, pesando 62±1,8kg. Coletou-se 900 mL de sangue total de cada animal, em duas bolsas plásticas tipos CPDA-1 (citrato-fosfato-dextrose-adenina) e CPD/SAG-M (citrato-fosfato-dextrose com solução aditiva de salina-glicose-manitol), armazenadas sob refrigeração (2-4 °C) durante 42 dias. Amostras de sangue foram coletadas das bolsas no início do estudo (T0) e depois de sete, 14, 21, 28, 35 e 42 dias, para realização de análises hematológicas, bioquímicas, hemogasométricas e microbiológicas. Nas duas bolsas houve aumento da concentração de hemoglobina plasmática, grau de hemólise, lactato, pO2 e redução de hemoglobina total e pH (p<0,05), porém não houve variação no número de hemácias, glicose, sódio e potássio quando comparado ao momento basal (T0). A bolsa CPD/SAG-M apresentou menor número de hemácias, volume globular, concentração de hemoglobina total e sódio, e maiores valores de grau de hemólise e hemoglobina plasmática em relação a bolsa CPDA-1 (P<0,05). Apesar de serem constatadas alterações em importantes variáveis do sangue caprino armazenado durante 42 dias em relação ao sangue fresco (T0), o sangue total caprino permaneceu viável para uso terapêutico. A análise comparativa entre os dois tipos de bolsa revelou uma similaridade de resultados para a grande maioria das variáveis estudadas, portanto a bolsa CPDA-1 pode ser considerada a mais indicada para uso na espécie caprina exclusivamente devido ao seu menor valor comercial.

ABSTRACT: The aim of this study was to evaluate the hematological, biochemical, and blood gas alterations of goat whole blood stored in different blood bags. Seven male, adult, crossbreed goats were used, weighing 62±1.8 kg. Nine hundred milliliters of whole blood from each animal was collected and stored in blood bags (450 ml in each), CPDA-1 (citrate phosphate dextrose-adenine) and CPD/SAG-M (citrate phosphate dextrose with saline-glucose-mannitol) as additive solutions, and kept refrigerated (2-4 ºC) for 42 days. Blood samples were collected from the plastic bags at baseline (T0) and after seven, 14, 21,28, 35, and 42 days for hematological, biochemical, blood gas, and microbiological evaluations. Free hemoglobin, degree of hemolysis, lactate, and pO2were increased in both bags, whereas hydrogen potential (pH) and the total hemoglobin concentration decreased overtime(P<0.05). The red blood cell count, glucose, sodium, and potassium remained stable, compared to the baseline. The CPD/SAG-M bag presented a lower red cell count, globular volume, total hemoglobin, and sodium, and a higher degree of hemolysis and plasma hemoglobin, compared with the CPDA-1 bag. The whole goat blood remained viable for therapeutic use; although, there were some important changes in the variables of the 42-day stored blood in relation to fresh blood (T0). We concluded that the CPDA-1 bag is more suitable for use in the storage of goat blood because of its lower commercial value.

Resumo Introdução: A ultrassonografia é um método emergente e ainda raramente utilizado na avaliação da congestão pulmonar. A congestão pulmonar é um importante fator de risco para eventos cardíacos e óbito entre pacientes com doença renal terminal (DRT) em hemodiálise (HD). Objetivo: Foram investigadas as possíveis variáveis associadas a congestão pulmonar em indivíduos diabéticos com DRT em HD, utilizando a ultrassonografia torácica para detectar água extracelular nos pulmões. Métodos: Foram estudados 73 pacientes com diabetes como causa primária de DRT submetidos a HD regular. A congestão pulmonar foi avaliada pela contagem do número de linhas B detectadas por ultrassonografia torácica. O estado de hidratação foi avaliado por análise de bioimpedância e a função cardíaca por ecocardiografia. O índice de colabamento da veia cava inferior (VCI) foi medido por ultrassonografia. Todos os pacientes foram classificados segundo a escore da NYHA. Foram analisadas as correlações entre o número de linhas B e variáveis contínuas e as comparações entre o número de linhas B em relação às variáveis categóricas. Regressão linear multivariada foi utilizada para testar as variáveis enquanto preditores independentes do número de linhas B. Resultados: Nenhuma das variáveis relacionadas a estado de hidratação e função cardíaca apresentou associação com o número de linhas B. Na análise multivariada, apenas o índice de colabamento da VCI (b = 45,038; p < 0,001) e as classes da NYHA (b = 13,995; p = 0,006) foram preditores independentes do número de linhas B. Conclusão: A avaliação clínica baseada na classificação da NYHA e na medição do índice de colabamento da VCI foram mais confiáveis do que a análise de bioimpedância para predizer congestão pulmonar.

Abstract Introduction: Ultrasound is an emerging method for assessing lung congestion but is still seldom used. Lung congestion is an important risk of cardiac events and death in end-stage renal disease (ESRD) patients on hemodialysis (HD). Objective: We investigated possible variables associated with lung congestion among diabetics with ESRD on HD, using chest ultrasound to detect extracellular lung water. Methods: We studied 73 patients with diabetes as the primary cause of ESRD, undergoing regular HD. Lung congestion was assessed by counting the number of B lines detected by chest ultrasound. Hydration status was assessed by bioimpedance analysis and cardiac function by echocardiography. The collapse index of the inferior vena cava (IVC) was measured by ultrasonography. All patients were classified according to NYHA score. Correlations of the number of B lines with continuous variables and comparisons regarding the number of B lines according to categorical variables were performed. Multivariate linear regression was used to test the variables as independent predictors of the number of B lines. Results: None of the variables related to hydration status and cardiac function were associated with the number of B lines. In the multivariate analysis, only the IVC collapse index (b = 45.038; p < 0.001) and NYHA classes (b = 13.995; p = 0.006) were independent predictors of the number of B lines. Conclusion: Clinical evaluation based on NYHA score and measurement of the collapsed IVC index were found to be more reliable than bioimpedance analysis to predict lung congestion.

ABSTRACT BACKGROUND Dengue fever may present hemorrhages and cavitary effusions as result of exacerbated immune responses. We investigated hydro-alcoholic extracts from leaves (UGL) and bark (UGB) of the medicinal species Uncaria guinanensis with respect to antiviral effects in Dengue virus (DENV) infection and in immunological parameters associated with in vivo physiopathological features. METHODS Chemical profiles from UGB or UGL were compared in thin layer chromatography and 1H nuclear magnetic resonance using flavonoid compounds and a pentacyclic oxindole alkaloid-enriched fraction as references. DENV-2-infected hepatocytes (Huh-7) were treated with extracts. Cell viability, DENV antigens and immunological factors were detected by enzyme-linked immunosorbent assay (ELISA) or flow cytometry. FINDINGS The UGL mainly differed from UGB by selectively containing the flavonoid kaempferitrin. UGB and UGL improved hepatocyte viability. Both extracts reduced intracellular viral antigen and inhibited the secretion of viral non-structural protein (NS1), which is indicative of viral replication. Reduction in secretion of macrophage migration inhibitory factor was achieved by UGB, of interleukin-6 by UGL, and of interleukin-8 by both UGB and UGL. MAIN CONCLUSIONS The U. guianensis extracts presented, antiviral and immunomodulatory effects for DENV and possibly a hepatocyte-protective activity. Further studies may be performed to consider these products as potential candidates for the development of an herbal product for the future treatment of dengue.
