ABSTRACT Little is understood about the nutritional status of manganese (Mn) in oil palm (Elaeis guineensis Jacq.), further research is needed to provide technological support for greater productivity, especially on the dynamics of accumulation, recycling, immobilization and export. Thus, the objective of this work was to evaluate the dynamics of accumulation, immobilization, recycling, exportation and the efficiency of Mn use in oil palm plants at different ages. The experiment was carried out in a completely randomized design, with seven treatments (plant age: 2, 3, 4, 5, 6, 7, and 8 years of planting) and four replicates. The leaflets and male inflorescence were, the vegetative and reproductive organs with the highest Mn concentration, respectively. The accumulation of this nutrient in the tree crown predominated in the stipe through all years. The bunch exported the highest amount of Mn, especially in older plants. The oil palm immobilizes and recycles, more than exports, a large amount of Mn. The Mn use efficiency is increased as a function of the age of the crops in all the oil palm organs. In conclusion, the nutritional demand of oil palm is altered as a function of age, altering the dynamics of immobilization, recycling and exportation of Mn.

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 This work aimed to characterize some of the bioactive compounds of Eugenia punicifolia (Kunth) DC. fruit to enhance the knowledge of its functional potential. Ripe fruits were collected from the restinga of Maricá, in the state of Rio de Janeiro (RJ), Brazil. Bioactive compounds were analyzed by High Performance Liquid Chromatography (HPLC). Ascorbic acid (74.14 mg 100-1 g-1), lycopene (504 µg g-1) and total carotenoids (632 µg g-1) contents were superior to other fruits rich in these compounds. In fact, E. punicifolia fruits are an excellent source of carotenoids and can be considered a good source of ascorbic acid (vitamin C). Furthermore, its chemical composition has presented phenolic compounds like gallic acid and anthocyanins. Thus, this underutilized Brazilian fruit stands out as a source of bioactive compounds, presenting a good potential as a functional food, especially due to the high content of lycopene.

Resumo Este trabalho teve como objetivo caracterizar alguns dos compostos bioativos do fruto da Eugenia punicifolia (Kunth) DC. para aprofundar o conhecimento do seu potencial funcional. Frutos maduros foram coletados da restinga de Maricá-RJ, Brasil. Os compostos bioativos foram analisados por cromatografia líquida de alta eficiência. Os teores de ácido ascórbico (74,14 mg 100-1 g-1), licopeno (504 µg g-1) e carotenoides totais (632 µg g-1) foram superiores aos de outras frutas ricas nesses compostos. Os frutos de E. punicifolia são uma excelente fonte de carotenoides e podem ser considerados uma boa fonte de ácido ascórbico (vitamina C). Além disso, sua composição química apresentou compostos fenólicos, como ácido gálico e antocianinas. Assim, essa fruta brasileira subutilizada se destaca como fonte de compostos bioativos, apresentando um bom potencial como alimento funcional, principalmente devido ao alto teor de licopeno.

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.

ABSTRACT Global consumption of oilseeds has been growing progressively in the last five growing seasons, in which soybean represents 60% of this sector. Thus, in order to maintain a high production in the region of Rio Verde, State of Goiás, against the phytopathological problems, this study aimed to define the best spectral range for the detection of H. glycines and P. brachyurus by linear regressions in soybean at R3 stage, as well as the elaboration of mathematical models through multiple linear regressions. For this, soil and root were sampled in the experimental area, as well as a flight was performed with the Sentera sensor. Data were used for the elaboration of regressions and for the validation of 2 mathematical models. Significant values were observed in simple linear regression only for cysts, in the visible range, with a good R² value for the Green, Red and 568 nm bands, to nonviable cysts. When working with the stepwise statistics, better results are found for H. glycines, which now has an R²(aj) of 0.7430 and P. brachyurus is then detected. From the mathematical model obtained with the multiple linear regression for non-viable cysts with an R²(aj) of 0.7430, it is possible to detect the spatial distribution of nematodes across the soybean field, in order to perform a localized management, optimizing the applications. Good results are also possible using the mathematical model obtained by simple linear regression.

Abstract Introduction : The scientific production of the areas of physical therapy and occupational therapy presented important growth and international visibility. Objective : To evaluate technical and scientific indicators, in addition to the training of human resources, of scholarship researchers of scientific productivity of CNPq (PQ), in the area of physical therapy and occupational therapy. Methods : A cross-sectional, census and quantitative study was conducted from the Lattes curricula of CNPq researchers with active scholarships in December 2021. The information was extracted through the Lattes Platform of CNPq, including three dimensions of variables for analysis: a) researcher profile; b) scientific production; c) training of human resources. Results : The evaluation included 73 PQ CNPq, in the areas of physical therapy and occupational therapy. The majority were female (n = 42; 57.5%), distributed in 26 different institutions in the country, with the Southeast region being the most prevalent. The largest portion of the PQ completed their doctorate between 11 and 20 years ago (n = 41; 56.2%) and did postdoctoral work (n = 55; 75.3%) abroad (n = 32; 58.2%). The group published 9,486 scientific articles throughout its career, averaging 129.94 scientific articles per PQ. The group of PQ supervised a total of 2,561 undergraduate students, 1,748 master’s and 800 doctoral students. The mean H index of PQ was 19.74 (CI 95% = 18.40-21.11; SD = 5.71; median = 19). Conclusion : The PQ scholarship researchers presented significant scientific production and training of human resources, which confirms the important development of the areas in the last ten years. However, a strong nucleation of this production was observed.

ABSTRACT Purpose: To evaluate the viability of the porcine vas deferens as a realistic microsurgical training model for vasectomy reversal Methods: The model uses swine testicles (vas deferent), which are usually discarded in large street markets since they are not part of Brazilian cuisine. The spermatic cord was carefully dissected, and the vas deferens were isolated, measuring 10 cm in length. A paper quadrilateral with 5 cm2 was built to delimit the surgical training field. The objective of the model is to simulate only the microsurgical step when the vas deferens are already isolated. The parameters analyzed were: feasibility for reproducing the technique, patency before and after performing the vasovasostomy, cost of the model, ease of acquisition, ease of handling, execution time, and model reproducibility. Results: The simulator presented low cost. All models made were viable with a texture similar to human, with positive patency obtained in 100% of the procedures. The internal and external diameters of the vas deferens varied between 0.2-0.4 mm and 2-3 mm, respectively, with a mean length of 9 ± 1.2 cm. The total procedure time was 43.28 ± 3.22 minutes. Conclusions: The realistic model presented proved to be viable for carrying out vasectomy reversal training, due to its low cost, easy acquisition, and easy handling, and providing similar tissue characteristics to humans.

Em uma era onde a prevalência de dados se faz marcante, a importância da adoção de técnicas computacionais avançadas, como a inteligência artificial e o aprendizado de máquina, torna-se fundamental no processo de formação dos físicos de amanhã. Este artigo introduz uma abordagem inovadora para o ensino de física, incorporando o aprendizado de máquina ao estudo clássico do pêndulo simples. São introduzidos os conceitos das técnicas de aprendizado de máquina e coletado um conjunto amplo de dados por meio da observação acurada do movimento do pêndulo em diferentes condições iniciais. A partir desses dados, é empregado um algoritmo de regressão para criar um modelo do sistema do pêndulo com índices estatísticos satisfatórios. Este modelo pedagógico se contrasta com os métodos tradicionais de ensino de física e abre um novo horizonte para a compreensão do que significa o ensino de física na era da informação. marcante avançadas tornase torna amanhã simples iniciais satisfatórios informação

In an era where the prevalence of data is striking, the importance of adopting advanced computational techniques, such as artificial intelligence and machine learning, becomes fundamental in the training process of tomorrow’s physicists. This article introduces an innovative approach to physics education, incorporating machine learning into the classic study of the simple pendulum. Key concepts of machine learning techniques are introduced and a broad dataset is collected through accurate observation of the pendulum’s motion under different initial conditions. From these data, a regression algorithm is employed to create a model of the pendulum system with satisfactory statistical indices. This pedagogical model contrasts with traditional physics teaching methods and opens a new horizon for understandding what it means to teach physics in the information age. striking tomorrows tomorrow s physicists education pendulums conditions indices age

ABSTRACT Introduction: It has been suggested that preeclampsia can be prevented by vitamin E and C intake, given the pathophysiological mechanism of this disease. Objective: To determine the joint efficacy of vitamin C and E in the prevention of preeclampsia. Methods: Systematic review of randomized clinical trials. A search of pubmed/medline, SCOPUS, Web of Science, Cochrane Library, EMBASE, and Clinical Trials databases was performed. The risk of bias of the randomized clinical trials was assessed using the Cochrane tool version 2. A random-effects meta-analysis was performed and relative risks were calculated, with corresponding 95 % confidence intervals. Results: Seven studies were included (n= 1 475). No statistically significant association of treatment with vitamin C and E supplementation was found with respect to preeclampsia (relative risks: 1.03; 95 % CI 0.78-1.26). Conclusions: Dual vitamin C and E supplementation does not prevent preeclampsia in pregnant women at risk for the disease.

RESUMEN Introducción: Se ha sugerido que la preeclampsia puede ser prevenida por la ingesta de vitamina E y C, dado el mecanismo fisiopatológico de esta enfermedad. Objetivo: Determinar la eficacia conjunta de la vitamina C y E en la prevención de la preeclamsia. Métodos: Revisión sistemática de ensayos clínicos aleatorizados. Se realizó una búsqueda en las bases de datos pubmed/medline, SCOPUS, Web of Science, Cochrane Library, EMBASE, y Clinical Trials. El riesgo de sesgo de los ensayos clínicos aleatorios se evaluó mediante la herramienta Cochrane versión 2. Se realizó un metanálisis de efectos aleatorios y se calcularon los riesgos relativos, con los correspondientes intervalos de confianza al 95 %. Resultados: Se incluyeron 7 estudios (n= 1 475). No se encontró asociación estadísticamente significativa del tratamiento con suplementación de vitamina C y E con respecto a la preeclampsia (riesgo relativo: 1,03; IC95 %: 0,78-1,26). Conclusiones: La suplementación dual de vitamina C y E no previene la preeclamsia en gestantes con riesgo de padecer la enfermedad.

Resumo Objetivo. O presente artigo objetivou comparar as representações sociais (RS) entre grupos de homens gays e heterossexuais sobre os comportamentos sexuais face ao isolamento social decorrente da pandemia da Covid-19. Método. Participaram 200 homens (100 heterossexuais e 100 homossexuais), com médias de idade de 27,06 e 28,12, respectivamente. Utilizou-se um formulário sociodemográfico on-line e uma entrevista semiestruturada com duas perguntas disparadoras para apreensão das RS. Os dados foram analisados pelo software IRAMUTEQ. Resultados. Verificou-se similaridades em ambos os grupos quanto a vida sexual ativa e uso de tecnologias para Sexting e acesso a pornografia. Entretanto, os homossexuais divergem na estrutura representacional ao buscarem estas estratégias compensatórias em maior quantidade, em razão de relacionamentos com pouca duração e/ou pouca união estável. Conclui-se que o distanciamento físico desvela intercorrências heterogêneas à vida afetivo-sexual nessa nova realidade social.

Abstract Objective. This article aimed to compare the social representations between groups of gay and heterosexual men about sexual behavior as a result of social isolation from the Covid-19 pandemic. Method. 200 men participated (100 heterosexuals and 100 homosexuals) with average age of 27.06 and 28.12, respectively. A sociodemographic questionnaire was used for sample characterization and a semi-structured interview for the apprehension of SR, with data processed by the IRAMUTEQ software. Results. Similarities were found in both groups in terms of active sex life and the use of technologies for sexing and access to pornography. However, homosexuals diverge in the representational structure when seeking greater compensatory strategies for having more stable civic states. It is concluded that physical distance reveals heterogeneous intercurrences to affective-sexual life in this new social reality.

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.
