TL;DR: School-based interventions that focus on changing dietary intake and physical activity levels to reduce childhood obesity may be an effective means for child obesity prevention and the identification of consistent elements used in school- based interventions that have demonstrated effectiveness may aid in preventing child obesity.
Abstract: Background. A systematised review was conducted to examine the effectiveness of school-based interventions that focus on changing dietary intake and physical activity levels to reduce childhood obesity. Methods. Multiple databases were searched for randomised and nonrandomised interventions from 2007 to 2016 in full-time elementary schools, which were delivered to the whole class, included dietary and physical activity components, involved both sexes, were written in English, and used body mass index (BMI) as an outcome. Results. The database search produced 8,866 titles from which 78 were deemed relevant and assessed for inclusion resulting in 15 studies meeting all inclusion criteria. From these 15 studies, 9 yielded a reduction or stabilisation in BMI or BMI z-score in the entire intervention group and/or subgroups. Programmes lasting between 6 and 12 months that involve multiple environmental, educational, and physical strategies appear to be most likely to result in BMI or BMI z-score improvement. Moderators most likely influencing an improvement in BMI included increased physical activity, decreased sugar sweetened beverages intake, and increased fruit intake. Conclusions. School-based interventions may be an effective means for child obesity prevention. The identification of consistent elements used in school-based interventions that have demonstrated effectiveness may aid in preventing child obesity.

TL;DR: This study analyzes the candidate mechanisms associated with muscle atrophy in stroke patients, as well as the modulatory effect of inflammation in this condition, and suggests the two strongest anti-inflammatory candidate mechanisms, myokines and the cholinergic anti- inflammatory pathway, which may be activated by physical exercise and contribute to a decrease in proinflammatory markers of poststroke patients.
Abstract: Inflammatory markers are increased systematically and locally (e.g., skeletal muscle) in stroke patients. Besides being associated with cardiovascular risk factors, proinflammatory cytokines seem to play a key role in muscle atrophy by regulating the pathways involved in this condition. As such, they may cause severe decrease in muscle strength and power, as well as impairment in cardiorespiratory fitness. On the other hand, physical exercise (PE) has been widely suggested as a powerful tool for treating stroke patients, since PE is able to regenerate, even if partially, physical and cognitive functions. However, the mechanisms underlying the beneficial effects of physical exercise in poststroke patients remain poorly understood. Thus, in this study we analyze the candidate mechanisms associated with muscle atrophy in stroke patients, as well as the modulatory effect of inflammation in this condition. Later, we suggest the two strongest anti-inflammatory candidate mechanisms, myokines and the cholinergic anti-inflammatory pathway, which may be activated by physical exercise and may contribute to a decrease in proinflammatory markers of poststroke patients.

TL;DR: Participation in the Wing of Baianas is associated with better balance with closed eyes, but there were no differences between dancers and non-dancers for muscle strength.
Abstract: Considering the growth of the aging population, and the increasing risk for falls and related morbidity, it is vital to seek efficient, comprehensive, and culturally relevant prevention programs for elderly people to reduce risks for falls. The aim of the present study was to evaluate the postural balance and muscle strength among women participating in the "Wing of Baianas" in the carnival parades. One hundred and ten women, with an average age of 67.4±5.9 years, were divided into two groups: Baianas group-elderly participants of the carnival parades in the "Wing of Baianas", and a Control group of women who do not dance samba. Assessments included a physical activity questionnaire, isokinetic muscle strength testing for the knee extensors and flexors, and a postural balance assessment completed on a force platform. There were no differences between groups, for postural balance outcomes, during the eyes open condition; however, with eyes closed, there was a significant effect between groups (Baianas vs Control) in all variables. The Baianas group showed less medio-lateral displacement (p < 0.04); and anteroposterior displacement (p < 0.007); larger amplitudes of medio-lateral displacement (p < 0.001); and anteroposterior displacement (p < 0.001); increased mean velocity (p < 0.01); and elliptical area (p < 0.01) There were no differences in the isokinetic peak torque corrected by body weight, total work and flexor/extensor ratio. Participation in the Wing of Baianas is associated with better balance with closed eyes, but there were no differences between dancers and non-dancers for muscle strength.

TL;DR: The results suggest that aerobic and, for the first time, dynamic resistance training were able to reduce sympathetic tonus to the heart and vessels, as well as preventing the increase in pro-inflammatory cytokine concentrations in the left ventricle of trained groups.
Abstract: We evaluated the effects of aerobic and resistance exercise training on ventricular morphometry and function, physical capacity, autonomic function, as well as on ventricular inflammatory status in trained rats prior to myocardial infarction. Male Wistar rats were divided into the following groups: sedentary+Sham, sedentary+myocardial infarction, aerobic trained+myocardial infarction, and resistance trained+myocardial infarction. Sham and myocardial infarction were performed after training periods. In the days following the surgeries, evaluations were performed. Aerobic training prevents aerobic (to a greater extent) and resistance capacity impairments, ventricular dysfunction, baroreflex sensitivity and autonomic disorders (vagal tonus decrease and sympathetic tonus increase) triggered by myocardial infarction. Resistance training was able to prevent negative changes to aerobic and resistance capacity (to a greater extent) but not to ventricular dysfunction, and it prevented cardiovascular sympathetic increments. Additionally, both types of training reduced left ventricle inflammatory cytokine concentration. Our results suggest that aerobic and, for the first time, dynamic resistance training were able to reduce sympathetic tonus to the heart and vessels, as well as preventing the increase in pro-inflammatory cytokine concentrations in the left ventricle of trained groups. These data emphasizes the positive effects of aerobic and dynamic resistance training on the prevention of the negative changes triggered by myocardial infarction.

TL;DR: The data suggest a tendency to better results of hypertrophy in animal groups that consumed the AP diet, even the sedentary animals, although more evident in those trained.
Abstract: Introduction. Sarcopenia is a process characterized by reduction in protein mass and muscle strength with increasing age, especially in the postmenopausal period, resulting in functional limitations and with great impact on the physical autonomy of the elderly. Objective. To evaluate the effects of diets with vegetable proteins (VP) or animal proteins (AP) associated with resistance training (RT) on the structural and biochemical parameters of the medial gastrocnemius muscle in Wistar rats with sarcopenia. Methods. An experimental model with ovariectomized rats was used to induce sarcopenia and resistance training. The histochemical technique was used for the typing of muscle fibers, the cross-sectional area of myocytes, and volume densities of myocytes and interstitium; the technique of Picrosirius stain was used to highlight the collagen fibers. Results. The VP diet was not able to minimize the effects of sarcopenia in the medial gastrocnemius of sedentary animals and when associated with RT, it promoted maintenance of the CSA, attenuating the atrophy of type IIB fibers in the medial gastrocnemius. The AP diet in sedentary animals protected the type I fibers. When combined with RT, the AP promoted muscle remodeling, with reduction in volume density of type I and IIA fibers, and increase of IIB fibers, together with an increase in collagen volume density. Conclusion. The data suggest a tendency to better results of hypertrophy in animal groups that consumed the AP diet, even the sedentary animals, although more evident in those trained.

TL;DR: In this paper, the morphometric patterns of lymph nodes of the head and neck, evaluating their number, shape, dimensions, hilum, and cortex, through the use of ultrasound examination of the neck.
Abstract: Objective: To show the morphometric patterns of lymph nodes of the head and neck, evaluating their number, shape, dimensions, hilum, and cortex, through the use of ultrasound examination of the neck. Materials and Methods: We analyzed 400 right and left lymph nodes in a group of 20 healthy young and middle-aged individuals of both genders. Results: In the ultrasound examination, we observed the following lymph nodes: mastoid; parotid (superficial, extraglandular, and intraglandular); submandibular (preglandular, retroglandular, and intracapsular); submental; and cervical (anterior and posterior). Although some individuals had up to seven lymph nodes in the same region, most had only two to three per region. The smallest lymph node diameter observed was 0.4 cm, and the largest was 2.7 cm. Most lymph nodes showed an elongated or oval shape. Most of the lymph node hila were echogenic, although a few were hyperechoic. However, the cortex was clearly hypoechoic in all of the lymph nodes evaluated. Conclusion: Ultrasound examination of healthy individuals allowed the characteristics of the lymph nodes of the head and neck to be observed clearly, which could provide a basis for the analysis of patients with diseases of these lymph nodes.

TL;DR: The physiological adaptation effect of a physical activity program with increasing complexity and load, in a boy and a girl with Prader–Willi syndrome is assessed by assessing changes in lipid profile, body composition, and physical fitness parameters.
Abstract: Physical activity programs are a powerful tool against several diseases including obesity and their comorbidities. Prader–Willi syndrome is the most common genetic disease associated with obesity, and brings with it behavioral and emotional problems that need complex management. Research into the effect of physical activity programs on Prader–Willi syndrome is limited and it is frequently argued that if a physical activity program is too complex, the participants are more likely to drop out. Therefore, in this study, we assessed the physiological adaptation effect of a physical activity program with increasing complexity and load, in a boy and a girl with Prader–Willi syndrome by assessing changes in lipid profile, body composition, and physical fitness parameters. Case 1 was an 11-year-old girl, mixed race (brown), with an intelligence quotient of 68, 52.0 % body fat, and a body mass index of 45.3 kg/m2. The Prader–Willi syndrome diagnosis was made when she was 5-years old and was found to be due to an imprinting genomic defect. Case 2 was a 14-year-old boy, mixed race (brown), with an intelligence quotient of 74, 48.8 % body fat, and a body mass index of 37.3 kg/m2. The diagnosis was made when he was 10-years old and was found to be caused by gene deletion. Both participants presented physical characteristics and behavior problems typical of Prader–Willi syndrome. Case 2 presented high blood pressure, high cholesterol and sleep apnea and had to use continuous positive airway pressure to sleep. Both participants were assessed for 12 weeks (three times a week) using a physical activity program designed to improve strength and muscle hypertrophy. The work load was progressively adjusted as necessary and new exercises were added to the program. Prior to the program, the participants’ parents received instructions about managing problem behavior and advice about nutrition. After physical activity program several health markers assessed by biological tests and parental report had improved in both participants. The participants positively accepted the adaptations made to the physical activity program during the study. More studies are necessary to assess the benefits of physical activity in the Prader–Willi syndrome population.
TL;DR: In this article, a prevalencia de inatividade fisica e associacao with variaveis socioculturais was found to be high among adolescentes.
Abstract: Objetivou-se estimar a prevalencia de inatividade fisica em adolescentes e analisar sua associacao com variaveis socioculturais. A amostra foi constituida por 1.060 adolescentes. A inatividade fisica foi mensurada com o IPAQ versao curta e as informacoes socioculturais analisadas foram obtidas atraves de uma entrevista. Os resultados indicam que 69,5% dos adolescentes de ambos os sexos foram classificados como inativos fisicamente. As variaveis associadas a inatividade fisica foram o local de nascimento do pai, morar apenas com a mae, nao ser estimulado pelo professor e nao consumir alimentos saudaveis. Conclui-se que a prevalencia de inatividade fisica em adolescentes foi elevada e parecem sofrer influencia dos fatores socioculturais.

TL;DR: It is concluded that the type of plantar arch does not influence postural balance, and of the anthropometric factors, only foot length was related to postural Balance.
Abstract: The maintenance of posture is a constant challenge for the body, as it requires rapid and accurate responses to unforeseen disturbances, which are needed to prevent falls and maintain balance. The purpose of the present study was to compare different types of plantar arch in relation to postural balance, and analyze the relationships between variations the plantar arch and anthropometric characteristics of the feet with unipedal static balance. We evaluated 100 men and women between the ages of 20 and 40 years old, to determine anthropometry and posturography with a force platform. There was a weak correlation between plantar arches and anthropometric measurements and postural balance, except for the length of the male foot, which showed a correlation between increased size and poorer static balance. We conclude that the type of plantar arch does not influence postural balance, and of the anthropometric factors, only foot length was related to postural balance.

TL;DR: In this article, the authors analyzed psychological treatments to BDD, intervention proposals, the issues that were addressed, research type's and designs chosen, by reviewing scientific production in the database Bireme and PubMed.
Abstract: Body Dysmorphic Disorder (BDD) is characterized by a distorted perceptive behavior towards one body’s image and a concern with an imaginary defect in one’s appearance or an exaggerated distress about identified physical imperfections. The purpose of this research was to analyze psychological treatments to BDD, intervention proposals, the issues that were addressed, research type’s and designs chosen, by reviewing scientific production in the database Bireme and PubMed. A total of 83 articles on the subject were examined. Among them descriptive researches refer to 73% of the analyzed productions, whereas experimental research corresponds to the remainder 27%. In this latest group, different designs were observed, with researches based in control groups being however preponderant. In relation to the issues that were approached by the articles, it is remarkable that most of the studies analyzed proposed to make comparisons between individuals diagnosed with BDD with control groups (24%) and explore the characterization of BDD (23%). The most adequate treatment and epidemiology remain as issues to be explored. Keywords: body image, systematic review, body dysmorphic disorder.

TL;DR: In this paper, the authors analyze and discuss the constraints and conceptual influences (architectural and artistic) that led architect Frank Gehry to change the way he designed in the early 1980s.
Abstract: This paper analyzes and discusses the constraints and conceptual influences (architectural and artistic) that led architect Frank Gehry to change the way he design in the early 1980. The object propose to study these phenomena is the Winton guest house, designed between 1982 and 1985. The oeuvre is considered a key work in the evolution of the architect’s creative process and was defined by Philip Johnson as the ‘80s archetype house. The small building has been addressed by critics (and its author, too) to considerations of a work of art, a sculpture. In 2008 the small house was dismantled and transferred to a new location to serve as exhibition space. However, it was auctioned in 2015 and will again be disassembled and transferred to another location and will serve another use, both remain unknown. This transformation of the house into a “mobile object”, much like a sculpture than a house, can be regarded as a statement of its current existence as a work of art, the paper, however, takes this discussion to the time of work pregnancy in order to better understand the paths trodden by the architect to design such an oeuvre. Keywords: arts and architecture, Philip Johnson, architectural composition.

TL;DR: This paper describes the experimental characterization of MOS bipolar pseudo-resistors for a general purpose technology, proving that they are well suited for bio-amplifier applications.
Abstract: This paper describes the experimental characterization of MOS bipolar pseudo-resistors for a general purpose technology. Very-high resistance values can be obtained in small footprint layouts, allowing the development of high-pass filters with RC constants over 1 second. The pseudo-resistor presents two different behavior regions, and as described in this work, in bio-amplifiers applications, important functions are assigned to each of these regions. 0.13 μm 8HP technology from GlobalFoundries was chosen as the target technology for the prototypes, because of its versatility. Due to the very-low current of pseudo-resistors, a circuit for indirect resistance measurement was proposed and applied. The fabricated devices presented resistances over 1 teraohm and preserved both the linear and the exponential operation regions, proving that they are well suited for bio-amplifier applications.
TL;DR: Palavras-chave et al. as discussed by the authors argue that the dominant approach to the enforcement of competition law has legitimized one of its defining traces, the concentration of economic power.
Abstract: DOI: 10.12957/dep.2016.26512 Abstract The intriguing coincidence between the global diffusion, in the 1990s, of measures of privatization and market liberalization characteristic of neoliberalism, and the worldwide spread of competition laws to control the economic power of corporations has been often naturalized or silenced. How to make sense of the fact that the liberalization of markets was accompanied by more regulation directed to control the behavior of corporations? The hypothesis here developed is that competition law, as it has been practiced, contributed to the production of an economic arrangement propelled by neoliberal ideals. I argue that the dominant approach to the enforcement of competition law has legitimized one of its defining traces, the concentration of economic power. To illustrate this hypothesis, the article gathers empirical evidence from a case study of the enforcement of the regulation of economic power by the Brazilian competition authority, the Administrative Council for Economic Defence (CADE), between 1994 and 2010. Keywords: competition law – economic concentration – neoliberalism – CADE Resumo Com frequencia, a intrigante coincidencia entre a difusao global, nos anos 1990, de medidas de privatizacao e liberalizacao de mercado caracteristicas do neoliberalismo e a criacao e reforma de leis de concorrencia para controlar o poder economico das empresas e silenciada ou naturalizada. Como explicar que a liberalizacao dos mercados foi acompanhada de mais regulacao voltada a controlar o comportamento das empresas? A hipotese desenvolvida neste artigo e que a regulacao concorrencia, da maneira que foi implementada, compatibilizou-se com a producao de um arranjo economico propagado pelos ideais neoliberais. Argumento que a abordagem dominante sobre a aplicacao do direito concorrencial (enforcement) legitimou um dos tracos definidores do neoliberalismo, a concentracao do poder economico. Para ilustrar essa hipotese, o artigo reune evidencias empiricas de um estudo de caso sobre a pratica da regulacao do poder economico pelo Conselho Administrativo de Defesa Economica (CADE) no Brasil, entre 1994 e 2010. Palavras-chave: direito da concorrencia – concentracao economica – neoliberalismo – CADE

Abstract: O objeto de estudo deste artigo e a cidade de Santos, mais especificamente a gestao publica municipal, no que se refere aos projetos para a regiao central da cidade e as suas implicacoes sociais. Devido a vertiginosa valorizacao do solo urbano em Santos nos ultimos 15 anos, combinada com uma gestao publica marcada pelo patrimonialismo e pelo crescente atendimento aos interesses do grande capital privado, houve dois processos bastante nitidos na cidade: a) a expulsao de parcela da populacao de Santos, principalmente para outras cidades da Baixada Santista; b) a mercantilizacao do patrimonio arquitetonico e urbanistico, que tem sido preservado, desde que nao interfira nos interesses do mercado imobiliario. O trabalho apresenta como objetivo principal a descricao, a analise e a avaliacao das politicas publicas urbanas para o centro de Santos, no que tange ao seu conjunto de valores, logica de funcionamento, interesses atendidos e suas implicacoes sociais.

Abstract: O artigo analisa a producao do conhecimento sobre a formacao continuada de professores de Educacao Fisica na base de dados Education Resources Information Center (ERIC) e numa coletânea de 14 periodicos nacionais. O objetivo e fornecer uma visao geral das producoes e discutir as opcoes de pesquisa adotadas pelos pesquisadores, identificando evolucoes e tendencias. Foi possivel constatar uma transitoriedade nos 15 anos de producao analisada (2000-2014) e uma prevalencia de estudos que privilegiam a historicidade dos informantes. Quanto a natureza epistemologica, predominaram estudos fenomenologico-hermeneuticos e quanto aos metodos de pesquisa, os de natureza qualitativa. Os dados sugerem que ha espaco para se investigar a formacao continuada que compreenda o professor como um pesquisador de sua pratica e transformador de sua realidade.
