Abstract This study examines the relationship between religion and tobacco use among university civil servants in Rio de Janeiro, Brazil, that participated in waves 1 (1999, n = 4030) and 4 (2012-13, n = 2933) of the Pro-Saúde Study. We employed self-administered questionnaires and logistic regression models to estimate cross-sectional and longitudinal associations between the independent (religion) and dependent (smoking/non-smoking) variables adjusted for age, sex, race/color, marital status, religious attendance, and schooling. Our results show that Pentecostal evangelical respondents, for example, were less likely to smoke and initiate tobacco use between the two survey waves than those of Afro-Brazilian religions. This study contributes to understanding the relationship between religion and health by including longitudinal data on the transition to smoking and its stopping. It also indicates the importance of investigating the topic in relation to other health habits and conditions.

Resumen Este trabajo analiza la relación entre la religión y el uso del tabaco en funcionarios públicos de campus universitarios en Rio de Janeiro y participantes del Estudio Pró-Saúde en sus versiones 1 (1999, n=4030) y 4 (2012-13, n=2933). Para esta investigación, fueron utilizados cuestionarios autoadministrados; asociaciones transversales y longitudinales entre las variables independiente (religión) y dependiente (fumar/no fumar), al igual que se estimaron razones de probabilidad en modelos de regresión logística ajustados para edad, sexo, raza/color, situación conyugal, frecuencia religiosa y escolaridad. Se identificó que los encuestados evangélicos pentecostales, en contraste con aquellos de religiones afrobrasileñas, presentaron menor probabilidad de fumar y de iniciarse en el uso del tabaco entre las dos versiones de la encuesta. Este estudio contribuye al conocimiento sobre las relaciones entre religión y salud al incluir datos longitudinales sobre la transición para el tabaquismo y su interrupción e indica la pertinencia de la investigación sobre este tema en relación con otros hábitos y condiciones de salud.

Resume Cet article analyse la relation entre religion et tabagisme chez les fonctionnaires des campi universitaires de Rio de Janeiro et les participants à l’Étude Pró-Saúde des vagues 1 (1999, n=4030) et 4 (2012-13, n=2933) . Des questionnaires auto-administrés ont été utilisés; les associations transversales et longitudinales entre les variables indépendantes (religion) et dépendantes (fumeur/non-fumeur) ont été estimées via des rapports de cotes dans des modèles de régression logistique ajustés en fonction de l’âge, du sexe, de la race/couleur, de l’état matrimonial, de la fréquence religieuse et de l’éducation. Il a été identifié que les répondants évangéliques pentecôtistes, contrairement à ceux des religions afro-brésiliennes, étaient moins susceptibles de fumer et de commencer à consommer du tabac entre les deux vagues d’enquête. Cette étude contribue à la connaissance des relations entre religion et santé en incluant des données longitudinales sur le passage au tabac et son arrêt, et indique la pertinence d’approfondir le sujet en relation avec d’autres habitudes et conditions de santé.

Resumo Este trabalho analisa a relação entre religião e uso de tabaco entre funcionários públicos de campi universitários no Rio de Janeiro e participantes do Estudo Pró-Saúde em suas ondas 1 (1999, n=4030) e 4 (2012-13, n=2933). Foram utilizados questionários auto-administrados; associações transversais e longitudinais entre as variáveis independente (religião) e dependente (fumar/não fumar) foram estimadas via razões de chances em modelos de regressão logística ajustados para idade, sexo, raça/cor, situação conjugal, frequência religiosa e escolaridade. Foi identificado que respondentes evangélicos pentecostais, em contraste com aqueles de religiões afro-brasileiras, apresentaram menor chance de fumar e de iniciar o uso de tabaco entre as duas ondas da pesquisa. Este estudo contribui para o conhecimento sobre as relações entre religião e saúde ao incluir dados longitudinais sobre a transição para o tabagismo e sua cessação e indica a pertinência da investigação do tema em relação a outros hábitos e condições de saúde.

ABSTRACT Zinc is an essential micronutrient for plant metabolism and has been studied in several crops of economic interest. However, there is no evidence of its use in coconut crops. The objective of this study was to evaluate the influence of foliar zinc fertilization with doses of zinc on dwarf green coconut seedlings based on their nutritional status, growth attributes, and gas exchange. The experimental design consisted of randomized blocks, and the treatments consisted of different zinc doses (0, 5, 10, 15, 20, and 25 g per plant) with five replicates. Seedlings were positively influenced by zinc dose, mainly in terms of growth variables and gas exchange. Zinc fertilization reduced iron and manganese content and increased zinc concentrations in the leaf tissue. Zinc fertilization promoted an increase in leaf area, height, shoot dry mass, and total dry mass. Furthermore, zinc fertilization improved photosynthesis, transpiration, stomatal conductance, internal CO2 concentration, instantaneous water use efficiency, and intrinsic water use efficiency. The improvement in these growth indices and gas exchange, in most variables, was up to an estimated dose of approximately 16 g of zinc per plant and decreased with increasing doses.

RESUMO O zinco é um micronutriente de importância essencial para o metabolismo vegetal, é estudado para diversas culturas de interesse econômico, porém sem evidências de estudo para a cultura do coqueiro. Objetivou-se com este estudo avaliar a influência da fertilização com doses de zinco via foliar em mudas de coqueiro anão verde, por meio do estado nutricional, atributos de crescimento e trocas gasosas. O delineamento experimental foi em blocos ao acaso, e os tratamentos foram constituídos por doses de zinco (0, 5, 10, 15, 20 e 25 g por planta), com cinco repetições. As mudas foram influenciadas positivamente pelas doses de zinco principalmente nas variáveis de crescimento e nas trocas gasosas. No estado nutricional afetou de maneira decrescente o ferro e o manganês e aumentou o zinco no tecido foliar. O zinco proporcionou incrementos na área foliar, altura de plantas, massa seca da parte aérea e massa seca total. Além disso, melhorou a fotossíntese, transpiração, condutância estomática, concentração interna de CO2, eficiência instantânea do uso da água e eficiência intrínseca do uso da água. A melhora nesses índices de crescimento e trocas gasosas, na maioria das variáveis, foi até a dose estimada de aproximadamente 16 g de zinco por planta e diminuiu com o aumento das doses.

ABSTRACT Brazil is the seventh largest producer of mangoes in the world, and the São Francisco Valley is the main producing region, with ‘Kent’ as one of the main cultivars. Considering that irrigation management affects physiological events, production and fruit quality, the objective of this work was to evaluate the gas exchange in the leaves and fruit quality of ‘Kent’ mango subjected to controlled water deficit in the semi-arid region. The experiment was carried out in Petrolina-PE, semi-arid region of the São Francisco Valley. The experimental design used was randomized blocks, in a triple factorial scheme, with four irrigation depths (40, 60, 80 and 100% of crop evapotranspiration - ETc), three phenological stages (F1 - flowering, F2 - fruit growth, F3 - fruit maturation) and two production cycles (2018 and 2019), with four replicates. During the phenological stages, the physiological parameters of gas exchange were evaluated. After harvesting, the following parameters were evaluated: soluble solids content, titratable acidity, pH, firmness and peel color. Irrigation with a depth between 79.5 and 83.6% ETc during the evaluated stages promoted greater gas exchange in the leaves, greater firmness and acidity in the fruits. The reduction in irrigation depth in F1 and F3 reduced the soluble solids content, while in F2 the highest soluble solids content was obtained with irrigation between 68.24 and 74.5% ETc. The most suitable irrigation depth for ‘Kent’ mango cultivation depends on the purpose of the producer and on the phenological stage of the crop.

RESUMO O Brasil é o sétimo maior produtor de mangas do mundo e o Vale do São Francisco é a principal região produtora, tendo a ‘Kent’ como uma das principais cultivares. Considerando que o manejo da irrigação afeta a fisiologia, a produção e a qualidade dos frutos, o objetivo deste trabalho foi avaliar as trocas gasosas nas folhas e a qualidade dos frutos da mangueira ‘Kent’ submetida a déficit hídrico controlado no Semiárido. O experimento foi conduzido em Petrolina-PE, semiárido do Vale do São Francisco. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial triplo, com quatro lâminas de irrigação (40; 60; 80 e 100% da evapotranspiração da cultura - ETc), três estádios fenológicos (F1 - floração, F2 - crescimento de frutos e F3 -maturação de frutos) e dois ciclos produtivos (2018 e 2019), com quatro repetições. Durante os estádios fenológicos, foram avaliados os parâmetros fisiológicos de trocas gasosas. Após a colheita, foram avaliados: teor de sólidos solúveis, acidez titulável, pH, firmeza e coloração da casca. A irrigação com lâmina entre 79,5 e 83,6% da ETc durante as fases avaliadas proporcionou maiores trocas gasosas nas folhas, maior firmeza e acidez nos frutos. A redução na lâmina de irrigação na F1 e F3 diminuiu o teor de sólidos solúveis, enquanto que na F2 o maior teor de sólidos solúveis foi obtido com irrigação entre 68,24 e 74,5% da ETc. A lâmina de irrigação mais adequada para o cultivo da manga ‘Kent’ depende do propósito do produtor e da fase fenológica da cultura.

ABSTRACT Oil palm production is strategic in the Amazon with high productive potential, but information on its fertilization is still relatively scarce for the region. The objective of this work was to evaluate the effects of phosphorus, potassium and magnesium fertilizations on oil palm production in different years in the state of Pará, Brazil. The study was conducted in Tailândia, Northeastern of Pará, Eastern Amazon, Brazil. A randomized block design was used in a 4 x 2 x 3 x 2 factorial scheme, with four levels of phosphorus, two sources of phosphorus, three levels of potassium and two levels of magnesium. Oil palm production responded positively to the increase in phosphorus levels, and until the eighth year of age of the plants, there was greater production when triple superphosphate was applied. From the ninth year onwards, fertilization with phosphine provided a production equal to the supply of phosphorus with triple superphosphate. The application of potassium chloride increased the number, weight and production of the bunches from the sixth year. The supply of magnesium sulfate increased the average weight of the bunches. Thus, phosphorus, potassium and magnesium fertilizations become essential to increase oil palm production in the Northeast of Pará.

Abstract: En | Text: En | PDF: En

Abstract Food processing allows a wide variation in the final quality of the product, which directly depends on the quality of the raw material used, the processing conditions, storage and commercialization. Salting, for example, is one of the oldest methods used to preserve meat. In the meat industry, the incorporation of salts into products is commonly used to improve dietary functionality and ensure food safety. Thus, the objective of this review was to understand that the discarded matrix meat can be used to make jerky meat, adding value to the final product. The processing of jerked beef is based on the osmotic dehydration process in counter flow, promoted by the penetration of salt with consequent exit of water from the inter and extra fibrillar compartments to the surface, with subsequent drying. At the same time, myosin denaturation occurs as a result of high temperatures, as well as myoglobin oxidation, promoted by salt, increasing the susceptibility to protein oxidation. The use of discarded animal meat to make jerky adds value to the by-product, improving sensory quality.

ABSTRACT Insects are fundamental to biodiversity conservation in almost all ecosystems, and their population decline, and extinction directly result from environmental impacts. These facts are aggravated by the lack of knowledge of insect biodiversity, the so-called biodiversity deficits, especially the Linnean and Wallacean shortfalls. In freshwater ecosystems, biodiversity loss is higher among aquatic insects, and caddisflies comprise one of the most vulnerable orders. In this way, research focusing on describing new caddisfly species and understanding their distribution ranges will increase knowledge of caddisfly biodiversity. In the past 14 years, the team from the Laboratório de Entomologia Aquática “Prof. Dr. Claudio Gilberto Froehlich” (LEAq, Universidade Federal da Bahia, Brazil) and collaborators have been addressing these issues, resulting in 55 described species of caddisflies. Taxa in other insect orders have also received attention and an additional 16 species have been described (eight mayflies, four stoneflies, four neuropteran spongillaflies, and antlions). Here, eight caddisfly species are described and illustrated (Atopsyche froehlichi sp. nov., Austrotinodes zeferina sp. nov., Cernotina kariri sp. nov., Neoathripsodes froehlichi sp. nov., Notalina claudiofroehlichi sp. nov., Oecetis marcus sp. nov., Phylloicus froehlichi sp. nov., and Polycentropus claudioi sp. nov.), five of them in honor of LEAq’s patron. In addition, new distributional data are presented for 10 known species. A checklist of the caddisfly fauna of Bahia state is also presented, with 138 species, around 75% and 30% of them recorded and described by the LEAq team, respectively. Currently, for caddisflies, Bahia is the fifth most species-rich state in Brazil, and the first in the Brazilian Northeast region.

ABSTRACT BACKGROUND: The incidence of esophageal cancer is high in some regions and the surgical treatment requires reference centers, with high volume, to make surgery feasible. AIMS: To evaluate patients undergoing minimally invasive esophagectomy by thoracoscopy in prone position for the treatment of esophageal cancer and to recognize the experience acquired over time in our service after the introduction of this technique. METHODS: From January 2012 to August 2021, all patients who underwent the minimally invasive esophagectomy for esophageal cancer were retrospectively analyzed. In order to assess the factors associated with the predefined outcomes as fistula, pneumonia, and intrahospital death, we performed univariate and multivariate logistic regression analyses, accounting for age as an important factor. RESULTS: Sixty-six patients were studied, with mean age of 59.5 years. The main histological type was squamous cell carcinoma (81.8%). The incidence of postoperative pneumonia and fistula was 38% and 33.3%, respectively. Eight patients died during this period. The patient's age, T and N stages, the year the procedure was performed, and postoperative pneumonia development were factors that influenced postoperative death. There was a 24% reduction in the chance of mortality each year, associated with the learning curve of our service. CONCLUSIONS: The present study presented the importance of the team's experience and the concentration of the treatment of patients with esophageal cancer in reference centers, allowing to significantly improve the postoperative outcomes.

RESUMO RACIONAL: A incidência do câncer de esôfago é elevada em algumas regiões e o tratamento cirúrgico requer centros de referência com alto volume para viabilizar a cirurgia. OBJETIVOS: Avaliar os pacientes submetidos à esofagectomia minimamente invasiva, por toracoscopia na posição prona, para o tratamento do câncer de esôfago e conhecer a experiência adquirida ao longo do tempo em nosso serviço após a introdução desta técnica. MÉTODOS: De janeiro de 2012 a agosto de 2021, foram analisados retrospectivamente todos os pacientes submetidos à esofagectomia minimamente invasiva para câncer de esôfago. Para avaliar os fatores associados aos desfechos predefinidos de fístula, pneumonia e óbito intra-hospitalar, realizamos análises de regressão logística univariada e multivariada considerando a idade como fator importante. RESULTADOS: Foram estudados 66 pacientes, com idade média de 59,5 anos. O tipo histológico mais frequente foi carcinoma espinocelular (81,8%). A incidência de pneumonia pós-operatória e fístula foi de 38% e 33,3%, respectivamente. Oito pacientes morreram durante este período. A idade do paciente, os estágios T e N, o ano da realização do procedimento e o desenvolvimento de pneumonia pós-operatória foram fatores que influenciaram o óbito. Houve uma redução de 24% na chance de mortalidade, ano a ano, associada à curva de aprendizado do nosso serviço. CONCLUSÕES: O presente estudo mostrou a importância da experiência da equipe e da concentração do tratamento de pacientes com câncer de esôfago em centros de referência, possibilitando melhorar significativamente o resultado pós-operatório.

Abstract Background High-intensity interval training (HIIT) has been suggested as an alternative for continuous training (CT) in people with diabetes mellitus (DM) due to its short duration and potential to improve adherence to exercise. However, data on its impact on heart rate variability (HRV) are scarce. Objectives To assess and compare the effects of HIIT and CT on exercise capacity, HRV and isolated hearts in diabetic rats. Methods DM (intravenous streptozotocin, 45 mg.kg -1 ) and control (C) animals performed 20 sessions (5 days/week, 50 min, for 4 weeks) of CT on a treadmill (70% of maximal exercise capacity) or HIIT (cycles of 1:1min at 50% and 90% of maximal exercise capacity). HRV was assessed by continuous electrocardiogram, and cardiac function assessed in isolated perfused hearts. For data analysis, we used the framework of the multivariate covariance generalized linear model or one-way ANOVA followed by Tukey’s test, considering p<0.05 as significant. Results Higher exercise capacity (m/min) was achieved in HIIT (DM-HIIT: 36.5 [IQR 30.0-41.3]; C-HIIT: 41.5 [37.8-44.5], both n=10) compared to CT (DM-CT: 29.0 [23.8-33.0]; C-CT: 32.0 [29.5-37.0], both n=10) (p<0.001). Heart rate (bpm) was lower in DM compared to controls (p<0.001) both in vivo (DM-HIIT:348±51, C-HIIT:441±66, DM-CT:361±70, C-CT:437±38) and in isolated hearts. There were no differences in HRV between the groups. Maximum and minimal dP/dt were reduced in DM, except +dP/dt in DM-HIIT vs. C-HIIT (mean difference: 595.5±250.3, p=0.190). Conclusion Short-term HIIT promotes greater improvement in exercise performance compared to CT, including in DM, without causing significant changes in HRV.

Resumo Fundamento O treinamento intervalado de alta intensidade (HIIT) tem sido sugerido como alternativa ao treinamento contínuo (TC) em indivíduos com diabetes mellitus (DM) devido à sua curta duração e potencial para melhorar a adesão ao exercício. No entanto, dados sobre seu impacto sobre a variabilidade da frequência cardíaca (VFC) são escassos. Objetivos Avaliar e comparar os efeitos do HIIT e TC sobre a capacidade no exercício, VFC e corações isolados em ratos diabéticos. Métodos Animais diabéticos (estreptozotocina intravenosa, 45 mg.kg -1 ) e controles (C) realizaram 20 sessões de TC (5 dias/semana, 50 min, por quatro semanas) em esteira (70% da capacidade máxima de exercício) ou HIIT (ciclos de 1:1min a 50% e 90% da capacidade máxima de exercício). A VFC foi avaliada por eletrocardiograma contínuo, e a função cardíaca foi avaliada em corações isolados perfundidos. Para a análise dos dados, utilizamos a matriz do modelo linear generalizado de covariância multivariada ou o teste one-way ANOVA seguido pelo teste de Tukey, considerando um valor de p<0,05 como significativo. Resultados A capacidade de exercício (m/min) foi maior no grupo submetido ao HIIT [DM-HIIT: 36,5 (IIQ 30,0-41,3); C-HIIT: 41,5 (37,8-44,5), ambos n=10) em comparação ao grupo submetido ao TC [DM-TC: 29,0 (23,8-33,0); C-TC: 32,0 (29,5-37,0), ambos n=10) (p<0,001). A frequência cardíaca (bpm) foi mais baixa no grupo DM em comparação aos controles (p<0,001) tanto in vivo (DM-HIIT: 348±51, C-HIIT:441±66, DM-TC:361±70, C-TC:437±38) como nos corações isolados. Não houve diferenças na VFC entre os grupos. Os valores máximos e mínimos de dP/dt foram reduzidos no DM, com exceção da +dP/dt no grupo DM-HIIT vs. C-HIIT (diferença média: 595,5±250,3, p=0,190). Conclusão O HIIT de curto prazo promoveu melhora superior no desempenho no exercício em comparação ao TC, sem causar mudanças significativas na variabilidade da frequência cardíaca.

ABSTRACT Background: This cross-sectional study compared the general impact of cutaneous leishmaniasis (CL) and patient satisfaction with treatment and health services as perceived by those undergoing different therapeutic regimens in an endemic region in South-Eastern Brazil. We also investigated the factors associated with both outcomes (general impact and satisfaction). Methods: We included 84 patients with CL treated between 2018 and 2019 with intravenous meglumine antimoniate, liposomal amphotericin B, or intralesional meglumine antimoniate therapy. Data were collected through interviews that assessed sociodemographic characteristics, comorbidity status, access and use of health services for CL diagnosis and treatment, and the items of the Cutaneous Leishmaniasis Impact Questionnaire (CLIQ). The CLIQ is a psychometric questionnaire previously validated to assess the general impact of CL on patient satisfaction with treatment and health services. Multivariate logistic regression analysis was used to identify the factors associated with high CL impact and low patient satisfaction. Results: The general impact of CL and patient satisfaction with treatment and health services were not significantly associated with the therapeutic regimen. High CL impact was associated with low family income (odds ratio [OR]:3.3; 95% confidence interval [CI]:1.0-10.3), occurrence of complications/adverse effects during treatment (OR:7.7; 95%CI:2.4-25.6), and additional costs during diagnosis and/or treatment (OR:12.1; 95% CI:2.8-52.4). Low satisfaction was associated with high disease impact (OR: 9.5; 95% CI:2.7-33.9), occurrence of complications/adverse effects (OR:4.2; 95% CI:1.3-13.0), and high family income (OR:7.1; 95%CI:1.7-28.2). Conclusions: Our data support public health policies aimed at reducing the impact of CL and its treatment as well as the use of therapy with fewer adverse effects.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

RESUMO A geração de cenários sintéticos de vazões afluentes é particularmente importante em países como o Brasil, onde a geração de energia hidrelétrica desempenha um papel fundamental e é crucial lidar adequadamente com a incerteza da vazão futura. Este artigo apresenta um esforço colaborativo do setor elétrico brasileiro para aprimorar os modelos de geração de cenários de vazão, com foco em horizontes de até um ano. Cinco instituições propuseram metodologias diversas e a sua eficácia foi avaliada através de uma avaliação comparativa estruturada. Os resultados revelam os pontos fortes e as áreas de possíveis aprimoramentos em cada modelo. O modelo GHCen apresentou o melhor desempenho, destacando-se nas análises de curto prazo e de média móvel, enquanto o modelo PARX demonstrou desempenho superior em regiões específicas do Brasil. O PAR(p)-A, metodologia oficial no Brasil, foi o segundo melhor modelo na análise de médias móveis. Este artigo oferece informações valiosas para países que enfrentam desafios semelhantes de programação hidrotérmica e geração de cenários.

ABSTRACT Synthetic streamflow scenario generation is particularly important in countries like Brazil, where hydroelectric power generation plays a key role and properly handling the uncertainty of future streamflow is crucial. This paper showcases a collaborative effort within the Brazilian electrical sector to enhance streamflow scenario models, focusing on horizons up to one year. Five institutions proposed diverse methodologies, and their effectiveness was evaluated using a comparative framework. The results reveal the strengths and areas for improvement in each model. GHCen emerged as the top performer, excelling in both short-term and moving average analyses, while the PARX model demonstrated superior performance in specific regions. The PAR(p)-A, which is the official methodology in Brazil, was the second-best model in the moving average analysis. This research offers valuable insights for countries facing similar hydrothermal scheduling and scenario generation challenges.

Resumo Objetivos As estruturas capsulo-ligamentares do ombro funcionam como estabilizadores estáticos, juntamente com os músculos do bíceps e do manguito rotador, aumentando a superfície de contato da cavidade glenoide. Terminações nervosas livres e mecanorreceptores foram identificados no ombro; no entanto, existem alguns estudos que descrevem a presença desses nervos na inserção do bíceps. Este estudo teve como objetivo descrever a morfologia e distribuição de terminações nervosas utilizando imunofluorescência com protein gene product 9.5 (PGP 9.5) e microscopia confocal. Métodos Foram estudados seis complexos labrum-bíceps de seis cadáveres congelados frescos. Os espécimes foram cortados coronalmente e preparados pelo método de imunofluorescência. Tanto em hematoxilina e eosina (H&E) quanto em imunofluorescência, foi descrita a organização do tecido conjuntivo com fibras paralelas de colágeno. Resultados No estudo de H&E, foram visualizadas estruturas vasculares e algumas estruturas nervosas, que foram identificadas pela presença alongada da célula nervosa. Todas as amostras analisadas com imunofluorescência e microscopia confocal demonstraram baixa ocorrência de morfotipos de corpúsculos sensoriais e terminações nervosas livres. Identificamos terminações nervosas livres localizadas no labrum, inserção bicipital e terminações nervosas esparsas ao longo do tendão. Terminais corpusculares com aspecto fusiforme, cuneiforme e oval foram identificados no tendão. Conclusão Esses achados corroboram a hipótese de que a geração de dor nas lesões labrais superiores de anterior a posterior (SLAP, na sigla em inglês) deriva da parte mais proximal do cabo longo do bíceps e ainda mais do labrum superior. Estudos quantitativos futuros com um número maior de espécimes podem fornecer mais informações sobre esses sistemas sensoriais.

Abstract Objectives The capsuloligamentous structures of the shoulder work as static stabilizers, together with the biceps and rotator cuff muscles, increasing the contact surface of the glenoid cavity. Free nerve endings and mechanoreceptors have been identified in the shoulder; however, there are a few studies that describe the presence of these nerves in the biceps' insertion. The present study aimed to describe the morphology and distribution of nerve endings using immunofluorescence with protein gene product 9.5 (PGP 9.5) and confocal microscopy. Methods Six labrum-biceps complexes from six fresh-frozen cadavers were studied. The specimens were coronally cut and prepared using the immunofluorescence technique. In both hematoxylin and eosin (H&E) and immunofluorescence, the organization of the connective tissue with parallel collagen fibers was described. Results In the H&E study, vascular structures and some nerve structures were visualized, which were identified by the elongated presence of the nerve cell. All specimens analyzed with immunofluorescence and confocal microscopy demonstrated poor occurrence of morphotypes of sensory corpuscles and free nerve endings. We identified free nerve endings located in the labrum and in the bicipital insertion, and sparse nerve endings along the tendon. Corpuscular endings with fusiform, cuneiform, and oval aspect were identified in the tendon. Conclusion These findings support the hypothesis that the generation of pain in the superior labral tear from Anterior to posterior (SLAP) lesions derives from the more proximal part of the long biceps cord and even more from the upper labrum. Future quantitative studies with a larger number of specimens may provide more information on these sensory systems.

ABSTRACT BACKGROUND: Common mental disorders (CMDs) have been correlated with consequences in different domains of life. OBJECTIVE: To summarize the prevalence rates of CMDs and factors associated with them among students at Brazilian medical schools. DESIGN AND SETTING: Systematic review and meta-analysis of studies developed in Brazilian medical schools. METHODS: In October 2021, searches were carried out in seven electronic databases, in Google Scholar and in reference lists. Observational studies reporting prevalence rates of CMDs among students at Brazilian medical schools were sought. Variables associated with CMDs arising from multivariate regression models were included in the synthesis. A meta-analysis was developed using a random-effects model and the risk of bias was assessed using an instrument developed from previous references. RESULTS: Fourteen original studies were included. The pooled prevalence rate of CMDs among undergraduate students at Brazilian medical schools was 43.3% (95% confidence interval = 38.9% to 47.6%; I2 = 87%; n = 3,927). Among the nine studies in which multivariate analyses were conducted, five showed risk associations between CMDs and medical school-related dissatisfactions, among which the desire to abandon the medical course can be highlighted (n = 3). In three studies, CMDs were associated with sleep indicators. CONCLUSION: Considering that the prevalence of CMDs among medical students is higher than in the general population, we recommend that Brazilian medical schools should give greater attention to this topic, and should enable expansion of care offerings relating to mental health. SYSTEMATIC REVIEW REGISTRATION: Prospective Register of Systematic Reviews (PROSPERO) database (CRD42020142184).
