The aim of this study was to assess the dietary intake of MAFLD and explore a possible relationship between its inflammatory characteristics (assessed by Dietary Inflammatory Index-DII®), the degree of liver fibrosis (assessed by transient elastography), and the amount of alcohol intake. MAFLD patients were included (n = 161) and were classified, according to the amount of alcoholic intake, as MAFLD without alcohol intake (n = 77) and MAFLD with alcohol intake (n = 84), with 19 presenting harmful alcoholic consumption. Dietary intake was 1868 ± 415 kcal/day and did not present differences in energy or nutrient intake based on the presence of metabolic comorbidities. Patients with MAFLD and alcohol intake consumed significantly more energy and presented a tendency for higher intake of carbohydrates and sugar. Patients with harmful alcohol intake presented a higher intake of total fat and cholesterol compared with moderate alcohol intake. There were no differences in DII® based on fibrosis severity or the amount of alcohol consumption. This work contributes to the characterization of baseline dietary intake in MAFLD patients, paving the way to design more suited dietary interventional trials.info:eu-repo/semantics/publishedVersio

Percepção dos residentes de enfermagem sobre cuidados paliativos durante o treinamento em serviço / Perception of nursing residents about palliative care during training in service

Objetivo: conhecer a visão sobre as ações desenvolvidas pelos enfermeiros que são reconhecidas como cuidados paliativos e analisar a percepção dos residentes de enfermagem sobre os cuidados paliativos. Metodologia: Trata-se de um estudo realizado através de um questionário estruturado com perguntas fechadas e abertas, sendo de abordagem qualitativa de forma descritiva. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal do Estado do Rio de Janeiro (CEP/UNIRIO), parecer nº 3.207.717 e CAAE nº 99421618.1.0000.5285 Resultado:  60 residentes foram entrevistados, com idade média de 28 anos. Quanto ao ano de residência, 44 participantes estão cursando o primeiro ano e 16 o segundo. A partir questionários foi possível verificar a ligação que os participantes tinham em relação a temática de cuidado paliativo. Após obter a análise, emergiram três categorias: Alivio de sofrimento dor e conforto, cuidados voltados para qualidade de vida e tratamento curativo. Conclusão: Apesar dos dados obterem uma demonstração dos resultados satisfatória em relação ao conhecimento dos entrevistados, ainda existem lacunas entre a teoria e prática, que se faz necessário para o desenvolvimento destes profissionais. A aproximação com a temática é de extrema necessidade para a ciência do cuidar, visto que demanda de pessoas com doenças crônicas avançadas aumentarão nos próximos anos. Espera-se que essa pesquisa subsidie em mais estudos e que a enfermagem tenha domínio sobre o assunto

C7a, a Biphosphinic Cyclopalladated Compound, Efficiently Controls the Development of a Patient-Derived Xenograft Model of Adult T Cell Leukemia/Lymphoma

Adult T-cell leukemia/lymphoma (ATLL) is a highly aggressive disease that occurs in individuals infected with the human T lymphotropic virus type 1 (HTLV-1). Patients with aggressive ATLL have a poor prognosis because the leukemic cells are resistant to conventional chemotherapy. We have investigated the therapeutic efficacy of a biphosphinic cyclopalladated complex {Pd2 [S(−)C2, N-dmpa]2 (μ-dppe)Cl2}, termed C7a, in a patient-derived xenograft model of ATLL, and investigated the mechanism of C7a action in HTLV-1-positive and negative transformed T cell lines in vitro. In vivo survival studies in immunocompromised mice inoculated with human RV-ATL cells and intraperitoneally treated with C7a led to significantly increased survival of the treated mice. We investigated the mechanism of C7a activity in vitro and found that it induced mitochondrial release of cytochrome c, caspase activation, nuclear condensation and DNA degradation. These results suggest that C7a triggers apoptotic cell death in both HTLV-1 infected and uninfected human transformed T-cell lines. Significantly, C7a was not cytotoxic to peripheral blood mononuclear cells (PBMC) from healthy donors and HTLV-1-infected individuals. C7a inhibited more than 60% of the ex vivo spontaneous proliferation of PBMC from HTLV-1-infected individuals. These results support a potential therapeutic role for C7a in both ATLL and HTLV-1-negative T-cell lymphomas

Isotemporal substitution of inactive time with physical activity and time in bed: cross-sectional associations with cardiometabolic health in the PREDIMEDPlus study

Background: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Methods: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m2) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had ≥3 components of the metabolic syndrome. Inactive time, physical activity and time in bed were objectively determined using triaxial accelerometers GENEActiv during 7 days (ActivInsights Ltd., Kimbolton, United Kingdom). Multiple adjusted linear and logistic regression models were used. Isotemporal substitution regression modelling was performed to assess the relationship of replacing the amount of time spent in one activity for another, on each outcome, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Results: Inactive time was associated with indicators of obesity and the metabolic syndrome. Reallocating 30 min per day of inactive time to 30 min per day of time in bed was associated with lower BMI, waist circumference and glycated hemoglobin (HbA1c) (all p-values < 0.05). Reallocating 30 min per day of inactive time with 30 min per day of LPA or MVPA was associated with lower BMI, waist circumference, total fat, visceral adipose tissue, HbA1c, glucose, triglycerides, and higher body muscle mass and HDL cholesterol (all p-values < 0.05). Conclusions: Inactive time was associated with a poor cardio-metabolic profile. Isotemporal substitution of inactive time with MVPA and LPA or time in bed could have beneficial impact on cardio-metabolic health

Relationship between olive oil consumption and ankle-brachial pressure index in a population at high cardiovascular risk

The aim of this study was to ascertain the association between the consumption of different categories of edible olive oils (virgin olive oils and olive oil) and olive pomace oil and ankle-brachial pressure index (ABI) in participants in the PREDIMED-Plus study, a trial of lifestyle modification for weight and cardiovascular event reduction in individuals with overweight/obesity harboring the metabolic syndrome. Methods: We performed a cross-sectional analysis of the PREDIMED-Plus trial. Consumption of any category of olive oil and olive pomace oil was assessed through a validated food-frequency questionnaire. Multivariable linear regression models were fitted to assess associations between olive oil consumption and ABI. Additionally, ABI ≤1 was considered as the outcome in logistic models with different categories of olive oil and olive pomace oil as exposure. Results: Among 4330 participants, the highest quintile of total olive oil consumption (sum of all categories of olive oil and olive pomace oil) was associated with higher mean values of ABI (beta coefficient: 0.014, 95% confidence interval [CI]: 0.002, 0.027) (p for trend = 0.010). Logistic models comparing the consumption of different categories of olive oils, olive pomace oil and ABI ≤1 values revealed an inverse association between virgin olive oils consumption and the likelihood of a low ABI (odds ratio [OR] 0.73, 95% CI [0.56, 0.97]), while consumption of olive pomace oil was positively associated with a low ABI (OR 1.22 95% CI [1.00, 1.48]). Conclusions: In a Mediterranean population at high cardiovascular risk, total olive oil consumption was associated with a higher mean ABI. These results suggest that olive oil consumption may be beneficial for peripheral artery disease prevention, but longitudinal studies are needed

Predictive Power of the "Trigger Tool" for the detection of adverse events in general surgery: a multicenter observational validation study

Background In spite of the global implementation of standardized surgical safety checklists and evidence-based practices, general surgery remains associated with a high residual risk of preventable perioperative complications and adverse events. This study was designed to validate the hypothesis that a new “Trigger Tool” represents a sensitive predictor of adverse events in general surgery. Methods An observational multicenter validation study was performed among 31 hospitals in Spain. The previously described “Trigger Tool” based on 40 specific triggers was applied to validate the predictive power of predicting adverse events in the perioperative care of surgical patients. A prediction model was used by means of a binary logistic regression analysis. Results The prevalence of adverse events among a total of 1,132 surgical cases included in this study was 31.53%. The “Trigger Tool” had a sensitivity and specificity of 86.27% and 79.55% respectively for predicting these adverse events. A total of 12 selected triggers of overall 40 triggers were identified for optimizing the predictive power of the “Trigger Tool”. Conclusions The “Trigger Tool” has a high predictive capacity for predicting adverse events in surgical procedures. We recommend a revision of the original 40 triggers to 12 selected triggers to optimize the predictive power of this tool, which will have to be validated in future studies

Estratégias de aquisição da casa própria: a trajetória de algumas famílias negras paulistanas nas décadas de 1920 a 1940

In Brazil, there is a cultural belief that property acquisition is the wisest attitude to ensure a safe and stable economy. For generations, the "dream of property ownership" has been cultivated as a horizon to be achieved. Confirming this tendency, since the 1920s, "casa propria" (home ownership) became a notion mobilized in the black press periodicals, circulating as a desirable aspiration and an orientation to the journals public. Between 1924 and 1937, two of the main newspapers of São Paulo black press, O Clarim da Alvorada and A Voz da Raça, carried out a campaign in favor of property ownership, spreading among paulista black families the importance of property acquisition. These campaigns are an important sign for the relevance of buying a property for black families at that time. In this paper, we seek to analyze it as an intergenerational social security strategy, through the presentation of three cases of black families that accomplished this goal between 1920s and 1940s. The black families testimonies reported here indicate precocity, specificities and strategies that represent new challenges for the formulation of property ownership problem, from a racial point of view.No Brasil, há uma crença cultural de que a atitude mais sábia para garantir uma economia doméstica segura e estável é a aquisição da casa própria. Por gerações, o “sonho da casa própria” tem sido cultivado como um horizonte a se atingir. Confirmando essa tendência, desde a década de 1920, a “casa própria” torna-se uma noção mobilizada nos periódicos da imprensa negra, circulando em diversos artigos como uma aspiração desejável e uma orientação ao público dos jornais. Entre 1924 e 1937, dois dos principais jornais da imprensa negra paulista, O Clarim da Alvorada e A Voz da Raça, realizaram uma campanha em favor da casa própria, difundindo entre as famílias negras paulistanas a ideia da importância da aquisição imobiliária. Essas campanhas constituem um indício importante da relevância da aquisição residencial para as famílias negras do período. Neste trabalho, procuramos analisar essa importância como estratégia de seguridade social intergeracional, por meio da apresentação de três casos de famílias negras que realizaram esse objetivo entre as décadas de 1920 e 1940. Os depoimentos das famílias negras aqui reportados indicamprecocidade, especificidades e estratégias que representam novos desafios para a reflexão sobre a formulação do problema da casa própria, a partir do ponto de vista racial

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types
