Avaliação da composição corporal de jogadores de futebol sub-20 da cidade de Uberlândia, Minas Gerais

Introduction: Football depends on several variables to be performed at its highest performance, among these variables, one of the most important is body composition, as it is related to the athlete's physical capacity and sports performance, which can influence the team's results. Objective: To evaluate the body composition of young soccer athletes, in an under-20 team. Methodology: Sixteen soccer players from a sub-20 team, aged 18 to 20 years, were evaluated. Weight and height were measured; in addition, they performed the electrical bioimpedance test to assess the parameters of body composition, mainly muscle mass and fat percentage. From the muscle mass, the muscle mass index (BMI) was calculated, dividing the total muscle mass by height in meters squared. Result: Most athletes were above the ideal fat percentage (n = 12), however, most individuals had values close to the ideal, which may have been a variation of the body composition assessment method itself. We observed that 4 individuals had an adequate percentage of fat. Regarding the IMM, the average values were within the normal range (10.9 ± 0.6 kg / m2), with only 4 athletes having little muscle mass. Conclusion: Almost all athletes had muscle mass within the normal range, while the majority had values above the adequate percentage of fat. These results show that future nutritional interventions should be carried out in these athletes, focusing mainly on reducing the percentage of fat.Trabalho de Conclusão de Curso (Graduação)Introdução: O futebol depende de diversas variáveis para ser realizado no seu mais alto rendimento, entre essas variáveis, uma das mais importantes é a composição corporal, pois está relacionada com a capacidade física e desempenho esportivo do atleta, podendo influenciar nos resultados da equipe. Objetivo: Avaliar a composição corporal de jovens atletas de futebol, em uma equipe sub-20. Metodologia: Foram avaliados 16 atletas de futebol de campo de uma equipe sub-20, com idade de 18 a 20 anos. Foram mensurados peso e estatura; além disso, fizeram o exame de bioimpedância elétrica para avaliar os parâmetros de composição corporal, principalmente massa muscular e percentual de gordura. A partir da massa muscular, foi calculado o índice de massa muscular (IMM), dividindo a massa muscular total pela altura em metros ao quadrado. Resultado: A maioria dos atletas estava acima do percentual de gordura ideal (n= 12), entretanto, a maior parte dos indivíduos apresentava valores próximos ao ideal, o que pode ter sido uma variação do próprio método de avaliação da composição corporal. Observamos que 4 indivíduos apresentavam percentual de gordura adequado. Em relação ao IMM, os valores médios estavam dentro da normalidade (10,9 ± 0,6 kg/m2 ), sendo que apenas 4 atletas apresentavam pouca massa muscular. Conclusão: Quase todos os atletas apresentaram massa muscular dentro da normalidade, enquanto que a maioria apresentou valores acima do adequado de percentual de gordura. Estes resultados mostram que devem ser realizadas futuras intervenções nutricionais nestes atletas, focando principalmente na redução do percentual de gordura

Recommendations of the neuroendocrinology department of the Brazilian society of endocrinology and metabolism for the diagnosis of Cushing’s disease in Brazil

Although it is a rare condition, the accurate diagnosis and treatment of Cushing’s disease is important due to its higher morbidity and mortality compared to the general population, which is attributed to cardiovascular diseases, diabetes mellitus and infections. Screening for hypercortisolism is recommended for patients who present multiple and progressive clinical signs and symptoms, especially those who are considered to be more specific to Cushing’s syndrome, abnormal findings relative to age (e.g., spinal osteoporosis and high blood pressure in young patients), weight gain associated with reduced growth rate in the pediatric population and for those with adrenal incidentalomas. Routine screening is not recommended for other groups of patients, such as those with obesity or diabetes mellitus. Magnetic resonance imaging (MRI) of the pituitary, the corticotropin-releasing hormone (CRH) test and the high-dose dexamethasone suppression test are the main tests for the differential diagnosis of ACTH-dependent Cushing’s syndrome. Bilateral and simultaneous petrosal sinus sampling is the gold standard method and is performed when the triad of initial tests is inconclusive, doubtful or conflicting. The aim of this article is to provide information on the early detection and establishment of a proper diagnosis of Cushing’s disease, recommending follow-up of these patients at experienced referral centers

Avaliação da influência de fatores sociais e econômicos no uso da metodologia PBL + M-Learning para o ensino da matemática

Embora o método de ensino tradicional seja predominantemente adotado nasescolas, os índices de avaliação estudantis apresentam dados alarmantes que ilustram a necessidade da busca por novas metodologias permanentes para o aprendizado. Diversos pesquisadores apresentam trabalhos que apontam o aprendizado baseado em problemas (PBL) e o aprendizado baseado no uso de plataformas móveis (m-learning) como caminhos para melhoria do desempenho dos estudantes. Este artigo analisa de modo tridimensional o uso do PBL e m-learning, considerando fatores sociais e econômicos no contexto da disciplina de matemática. A partir deste estudo, é possível inferir que fatores sociais e econômicos influenciam no sucesso da metodologia proposta, assim como, o impacto da metodologia no desempenho dos estudantes

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

We also request that researchers and teachers inform us of how they are using the data. © 2018 by the The Authors. Ecology © 2018 The Ecological Society of Americ

Modelo experimental estável de aneurisma sacular em artéria carótida de suínos utilizando veia jugular interna Stable experimental model of carotid artery saccular aneurysm in swine using the internal jugular vein

OBJETIVO: Desenvolver um modelo experimental estável de aneurisma sacular em carótida de suínos utilizando veia jugular interna. MÉTODOS: Em 12 suínos sadios, com peso variando entre 25 e 50kg, cinco machos e sete fêmeas, foi confeccionado aneurisma na artéria carótida comum direita. Após arteriotomia elíptica, foi realizada anastomose terminolateral com coto distal de veia jugular interna. O volume do aneurisma era calculado de maneira que o valor não excedesse em 27 vezes o valor da área da arteriotomia. Após seis dias, era realizada angiografia e análise microscópica do aneurisma para avaliar perviedade e trombose parcial ou total. RESULTADOS: Houve ganho de peso significante dos suínos no intervalo de tempo entre a confecção do aneurisma e a angiografia (p = 0,04). Foi observada perviedade aneurismática em dez suínos (83%). Ocorreram infecções de feridas operatórias em dois animais (16,6%), ambas com início de aparecimento em três dias após a confecção do aneurisma. Análise histológica dos aneurismas mostrou trombos ocluindo parcialmente a luz em nove suínos (75%). Nesses animais, observou-se que, em média, 9% da luz aneurismática estava preenchida por trombos. CONCLUSÃO: Pôde ser desenvolvido um modelo experimental estável de aneurisma sacular em carótida de suínos utilizando veia jugular interna.<br>OBJECTIVE: To develop an experimental model of stable saccular aneurysm in carotid of pigs using the internal jugular vein. METHODS: In 12 healthy pigs, weighing between 25 and 50kg, five males and seven females, we made a right common carotid artery aneurysm. After elliptical arteriotomy, we carried out a terminolateral anastomosis with the distal stump of the internal jugular vein. Aneurysm volume was calculated so that the value did not exceed 27 times the area of the arteriotomy. After six days angiography and microscopic examination were performed to assess patency of the aneurysm and the presence of total or partial thrombosis. RESULTS: There was a significant weight gain of pigs in the time interval between the manufacture of the aneurysm and angiography (p = 0.04). Aneurysmal patency was observed in ten pigs (83%). Operative wound infections occurred in two animals (16.6%), both with early onset, three days after the making of the aneurysm. Histological analysis showed aneurysm thrombus partially occluding the light in nine pigs (75%). In these animals, it was observed that on average 9% of the aneurysmal diameter was filled with thrombi. CONCLUSION: It was possible to develop a stable experimental model of saccular aneurysms in pig carotid artery by use of the internal jugular vein
