Cardiorespiratory fitness, but not central obesity or C-reactive protein, is related to liver function in obese children

Nonalcoholic fatty liver disease (NAFLD) is one of the most frequent complications associated with excess adiposity. Its pathogenesis is complex and there are multiple factors that may contribute to it. AIM: To analyze whether cardiorespiratory ftness (CRF), waist circumference (WC), and C-reactive protein (CRP) are associated with alanine aminotransferase (ALT) in children with obesity. METHODS: 79 overweight/obese children of both genders, 11-13 year-olds, with abnormal serum ALT from Porto public schools comprised the sample. Measurements included CRF (20-m Shuttle Run Test), WC (NHANES protocol), CRP and ALT (Cholestech LDX analyzer). Logistic regression adjusted for gender, maturation, and weight with ALT levels as dependent variable (risk vs. non risk), and WC (risk vs. non risk), CRP (risk vs. non risk), and CRF (fit vs. unfit) as independent variables. Level of significance was set at 95%. RESULTS: Logistic regression showed that obese fit children were less likely to have abnormal ALT values (OR=.031) CONCLUSION: In obese children, higher cardiovascular fitness appears to reduce the chance of decreased liver function. © 2013 Human Kinetics, Inc.

Metodologias para a avaliação do potencial fisiológico de sementes de tabaco

Despite tobacco being a culture propagated by seeds, there is little information concerning tests that allow the distinction of similar germination lots in different levels of vigor. The diversity of cultivars available in the market, and a few peculiarities of the species, such as uneven maturation of the flowers, fruits and seeds, small size and seed dormancy, are considered obstacles for obtaining lots of tobacco of high physiological potential. Thus, this research was developed with the objective of adapting feasibility and vigor tests for evaluating the physiological potential of tobacco seed lots. We used nine lots of tobacco seeds of cultivar CSC 447 and nine lots of seeds of cultivar BAT 2101, belonging to variety groups Virginia and Burley, respectively. Initially, germination test was conducted to characterize the profile of the lots. For determining the feasibility and vigor of the tobacco seeds, germination tests were conducted in distinct temperatures, controlled emergence conditions, electric conductivity, artificial aging and in tetrazolium. For determining the isoenzymatic marker for seed quality, analyses were conducted with enzymes catalase, esterase, malate dehydrogenase and alcohol dehydrogenase. In conclusion, the emergence tests at 25oC and artificial aging at 41oC for 72 hours, are efficient in discriminating the lots of tobacco seeds in different levels of vigor. The electric conductivity and germination tests in different temperatures have distinct responses in relation to the genotype of the tobacco seeds. The tetrazolium test using the methodology with pre-conditioning in 3.5% sodium hypochlorite solution and subsequent emersion in 1.0% tetrazolium solution for 18 hours is efficient for the quick evaluation of the feasibility of tobacco seeds. The analysis of the profiles of enzymes catalase, esterase, malate dehydrogenase and alcohol dehydrogenase is efficient as markers for tobacco seed quality.

Los métodos de estimación indirecta de variables sociodemográficas para áreas geográficas menores han experimentado un franco desarrollo en América Latina y el Caribe. Aunque algunos de estos métodos tienen referentes en trabajos que datan de varias décadas atrás, durante los años noventa confluyeron tres factores principales, que dieron un gran impulso a esta línea de investigación: a) el fuerte aumento de la demanda de este tipo de información, originado en exigencias legales vinculadas a la representación política o a ciertas asignaciones presupuestarias, en el marco de procesos de descentralización, ven la focalización de las políticas sociales en general; b) una mayor frecuencia, periodicidad y sistematización del levantamiento de encuestas de hogares y demográficas con representación nacional, urbana y rural, y c) la más amplia disponibilidad de medios computacionales de bajo costo y alta velocidad de procesamiento de bases de datos con varios miles o millones de registros individuales, como las encuestas y los censos de población y vivienda. En los artículos aquí reunidos, los temas y variables estudiados (población, prevalencia y demanda anticonceptiva, ingreso, pobreza), las fuentes de información utilizadas (registros vitales y administrativos, censos, encuestas) y los procedimientos de análisis y estimación (imputación proporcional simple, tipificación, análisis discriminante y de regresión) pueden aparecer, en una primera mirada, bastante disímiles. No obstante, los trabajos tienen importantes elementos en común, como el propósito de obtener estimaciones de indicadores de forma indirecta, cuando es imposible o insatisfactoria la estimación directa; el recurso a la combinación de dos o mas fuentes de información, y la especificación y elaboración de modelos estadísticos, en general de tipo multivariado, apropiados para el objetivo que se persigue.

O gênero opinativo "cartas do leitor": uma análise de appraisal

Esta pesquisa está fundamentada na visão sistêmico-funcional da linguagem e tem como objetivo principal descrever e analisar as categorias de appraisal, em 50 textos publicados na seção 'Cartas do Leitor', veiculada pela revista Veja, mostrando a importância das escolhas linguísticas na construção de significados relacionados à emoção do falante. Adotamos os pressupostos teóricos do lingüista Michael Halliday (1994) que concebe a linguagem como uma forma de ação sobre a realidade, por meio da qual o falante comunica três grupos de significados: ideacional, interpessoal e textual. Enfocamos a metafunção interpessoal, particularmente, a teoria de appraisal, defendida por Martin (2000), Martin e Rose (2003) e Martin e White (2005). A análise das expressões lexicais utilizadas na elaboração das cartas comprova que os escreventes recorrem às categorias de appraisal para extravasar o que sentem, positiva ou negativamente, seja para julgar comportamentos ou atitudes, seja para externar afetos ou desafetos, seja para apreciar pessoas ou objetos. Ficou constatado que, no gênero textual "Cartas do Leitor", há uma predominância da categoria avaliativa 'Julgamento'.

Apontamentos para uma reflexão sobre a pesquisa em saúde mental no contexto da reforma psiquiátrica

This paper is a contribution to the "IV Journey Research in Psychology: current challenges in the practice of psychology." The goal of this paper is to present some notes to produce reflections on research and the production of knowledge in the field of mental health in the context of the Brazilian Psychiatric Reform. Starting from two stories narrated by Ruben Alves, is intended to reflect on the characteristics of the current scenario of contemporary society and the role of knowledge production. These reflections will lead to a brief analysis of the impasses of scientific rationality. At the end, will be analyzed the context of psychiatric reform, his proposal of paradigmatic transition and will be presented some themes that guide the production of knowledge in this scenario.
