Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cellmediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal nonzinc- deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n = 31) and an experimental group (10 mg Zn/day, n = 31) for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1) an increased body mass index for age and an increased phase angle in the experimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3) increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients, including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups (p < 0.0001). Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.

Preeclampsia is a disease specific of human pregnancy that affects 3-8% of pregnant women, and it is one of the three leading causes of maternal mortality and morbidity. The disease is characterized by hypertension and proteinuria after the 20th week of gestation. The risk factors for this disease are not completely understood but appear to include dysregulation of the immune response arising from defects in placentation, environmental and genetic factors. This study aimed to determine whether the variation in the amount of proinflammatory cytokine receptors IL-1R2, IL-6R and TNF-αR1 would be involved in preeclampsia. They were recruited women with preeclampsia (n=24) and women who evolved during pregnancy without changes in blood pressure (n=12) were recruited. Clinical and laboratory data were collected. The cytokine receptors (IL-1R2, TNF-αR1 and IL-6R) were assessed in mononuclear cells isolated from peripheral blood using flow cytometry (Control = 8; PE = 24). C-reactive protein (CRP) was determined by CRP ultrasensitive method (Control = 7; PE = 18) was performed using sera pregnant women. Women with preeclampsia had higher weight at the beginning of the pregnancy (p=0.0171) and lower gestational age at delivery (0.0008). Classical monocytes were decreased in preeclampsia but not intermediate or non-classical monocytes. The frequency of IL-1R2 pro inflammatory cytokine receptors is decreased in women with PE only in the subpopulation of non-classical monocytes (p = 0.0011). TNF-αR1 receptor and IL-6R, had a decreased frequency in the three subpopulations of monocyte (classic, intermediate and non-classical) when compared to women with normal pregnancy. An increase in IL-1R2 receptor in TCD4+ lymphocytes, but a decrease in TNF-receptor and IL-6R in women with preeclampsia were found. No differences in the frequency of those receptors in CD3+/CD8+ in preeclampsia. There was no difference in C-reactive protein in preeclampsia. The reduction in the amount of IL-1R2, TNF- αR1 and IL-6R monocytes and lymphocytes can be involved in the regulation of inflammation observed in preeclampsia, contributing to disease.

In Brazil many types of bioproducts and agroindustrial waste are generated currently, such as cacashew apple bagasse and coconut husk, for example. The final disposal of these wastes causes serious environmental issues. In this sense, waste lignocellulosic content, as the shell of the coconut is a renewable and abundant raw material in which its use has an increased interest mainly for the 2nd generation ethanol production. The hydrolysis of cellulose to reducing sugars such as glucose and xylose is catalysed by a group of enzymes called cellulases. However, the main bottleneck in the enzymatic hydrolysis of cellulose is the significant deactivation of the enzyme that shows irreversible adsorption mechanism leading to reduction of the cellulose adsorption onto cellulose. Studies have shown that the use of surfactants can modify the surface property of the cellulose therefore minimizing the irreversible binding. The main objective of the present study was to evaluate the influence of chemical and biological surfactants during the hydrolysis of coconut husk which was subjected to two pre-treatment in order to improve the accessibility of the enzymes to the cellulose, removing this way, part of the lignin and hemicellulose present in the structure of the material. The pre-treatments applied to coconut bagasse were: Acid/Alkaline using 0.6M H2SO4 followed by 1M NaOH, and the one with Alkaline Hydrogen Peroxide at a concentration of 7.35% (v/v) and pH 11.5. Both the material no treatment and pretreated were characterized using analysis of diffraction X-ray (XRD), Scanning Electron Microscopy (SEM) and methods established by NREL. The influence of both surfactants, chemical and biological, was used at concentrations below the critical micelle concentration (CMC), and the concentrations equal to the CMC. The application of pre-treatment with coconut residue was efficient for the conversion to glucose, as well as for the production of total reducing sugars, it was possible to observe that the pretreatment fragmented the structure as well as disordered the fibers. Regarding XRD analysis, a significant increase in crystallinity index was observed for pretreated bagasse acid/alkali (51.1%) compared to the no treatment (31.7%), while that for that treated with PHA, the crystallinity index was slightly lower, around 29%. In terms of total reducing sugars it was not possible to observe a significant difference between the hydrolysis carried out without the use of surfactant compared to the addition of Triton and rhamnolipid. However, by observing the conversions achieved during the hydrolysis, it was noted that the best conversion was using the rhamnolipíd for the husk pretreated with acid/alkali, reaching a value of 33%, whereas using Triton the higher conversion was 23.8%. The coconut husk is a residue which can present a high potential to the 2nd generation ethanol production, being the rhamonolipid a very efficient biosurfactant for use as an adjuvant in the enzymatic process in order to act on the material structure reducing its recalcitrance and therefore improving the conditions of access for enzymes to the substrate increasing thus the conversion of cellulose to glucose.

The pre-salt province is composed by large amounts of light oil and with good quality, a reality that puts Brazil in a strategic position facing the great demand for energy worldwide. In this province are the largest discoveries in the world in the last ten years; areas as Libra, Franco and Lula field, everyone containing volumes greater than 8 billion recoverable oil barrels. To develop and optimize the production of these fields, a study was done for choosing the improved oil recovery methods. The main motivations were the presence of carbon dioxide (CO2) as a contaminant and the strategic decision of do not discard it, combined with high GOR (gas-oil ratio) of the reservoir fluid. The method should take advantage of the unique abundant resources: seawater and produced gas. This way, the process of matching these resources in the water alterning gas injection (WAG) became a good option. In this master’s dissertation, it was developed a reservoir model with average characteristics of the Brazilian pre-salt, where was applied the improved oil recovery method of water alternating gas. The production of this reservoir was analyzed by parameters as: the first fluid injected in the injection process, position of the injection wells completion, injection water and gas rate and cycle time. The results showed a good performance of the method, with up to 26% of gains in the recovery factor regarding the primary recovery, since the application of water injection and gas, individually, was not able to overcome 10 % of gain. The most influential parameter found in the results was the cycle time, with higher recovery factor values obtained with the use of shorter times.

O papel do enfermeiro como prescritor vem se ampliando em muitos países nos últimos anos, em diferentes situações e amplitudes de ação, se configurando como prática avançada na enfermagem. No Brasil, a prescrição de medicamentos por enfermeiros está prevista na Lei do Exercício Profissional desde 1986, e permite a esse profissional, a prescrição de medicamentos estabelecidos em programas de saúde pública. Esse estudo tem como objetivo geral analisar as determinações e perspectivas da prescrição de medicamentos por enfermeiros nos protocolos da Estratégia Saúde da Família. Os objetivos específicos são: apreender a atual situação internacional da prescrição de medicamentos por enfermeiros em comparação a essa prática no Brasil identificando semelhanças e diferenças; identificar os contornos legais e normativos da prescrição de medicamentos por enfermeiros no Brasil apontando sua história, tendências e desafios; caracterizar o modelo de prescrição de medicamentos por enfermeiros nos protocolos de Atenção Primária à Saúde no Brasil; investigar possíveis lacunas entre formação, capacitação, autoavaliação e prática da prescrição de medicamentos na Atenção Primária à Saúde na perspectiva do enfermeiro. Trata-se de Estudo de Caso Exemplar com abordagem qualitativa através de Revisão Bibliográfica, Análise Documental e Grupo Focal com enfermeiros. A análise dos dados deu-se por meio da Análise de Conteúdo e Análise Qualitativa de Conteúdo. Os resultados revelam que a categoria da enfermagem contribuiu para a legalização da prescrição, porém não para a sua legitimação; na Atenção Primária à Saúde, essa atribuição está consolidada por meio de protocolos e legislação, embora sem estratégia clara de acompanhamento pelo Ministério da Saúde; observa-se resistência em algumas normatizações dentro do setor saúde. Quanto aos protocolos, observou-se não há exigência de pré-requisitos na maioria deles; há possibilidade de diagnóstico pelo enfermeiro na gravidez, nutrição infantil e doenças sexualmente transmissíveis; observou-se variados graus de autonomia; amplo grupo de medicamentos prescritos por enfermeiros. Dos 37 participantes do Grupo Focal, 97,3% eram do sexo feminino; 54% formados há menos de 10 anos, 27% entre 10 e 20 anos, 16,2% há mais de 20 anos; 83,8% com especialização em Saúde Pública. Todos os enfermeiros relataram insuficiência da disciplina de farmacologia para instrumentalizar a prática prescritiva. Destacou-se a necessidade de pós-graduação; a importância da experiência clínica; falta de discussões e capacitação. Apenas alguns se autoavaliaram como competentes para prescrever, outros revelam medo de reação adversa a medicamentos. Conclui-se que há tendência da prescrição de medicamento por enfermeiros permanecer apenas na legalidade e o principal desafio é alcançar a legitimidade. Confirma-se uma prática prescritiva sem requisitos, diversidade de orientações induzindo a multiplicidade de ações que pode afetar a qualidade da prescrição. Há lacunas entre formação, capacitações e exigências cotidianas da prescrição de medicamentos por enfermeiros na Atenção Primária à Saúde. No Brasil se faz premente pesquisa para avaliar o impacto, a qualidade e a segurança da prescrição de medicamentos por enfermeiros. A experiência internacional sugere também que essa prescrição deve ser apoiada pelo coletivo de enfermeiros, com robusto plano de capacitação nacional, além de governança e apoio local.

O Brasil é um dos países que concentram 80% da carga de tuberculose no mundo. No contexto da atenção primária brasileira, fatores interferem para que as equipes de saúde da família possam incorporar as atividades de controle da doença no processo de trabalho. O controle da doença depende da forma como os serviços de saúde estão organizados para garantir o acesso ao diagnóstico precoce e ao tratamento. Esse estudo tem como objetivo geral analisar o controle da tuberculose no contexto da atenção primária à saúde no Brasil. Os objetivos específicos são comparar o tratamento diretamente observado com o regime autoadministrado em pessoas com tuberculose; Verificar se o Programa Nacional de Controle da Tuberculose é avaliável e elaborar um modelo teórico e lógico para avaliação deste programa; avaliar a relação entre porte populacional dos municípios e as características de estrutura e processo de cuidado a pacientes de tuberculose na atenção primária no Brasil. Realizou-se uma revisão sistemática, seguida de um estudo de avaliabilidade e de um estudo transversal. Os achados da revisão sistemática revelam que não houve diferença significativa entre os grupos de tratamento (observado e não observado) para cura (OR 1,06. IC95% 0,75 - 1,50) e para conclusão do tratamento (OR 1,64, IC 95% 0,79 - 3,42). Menor abandono no grupo com tratamento supervisionado e não houve diferença estatisticamente significativa entre os grupos (OR 0,73, CI 95% 0,58-0,92). O risco de morte foi maior no regime de tratamento autoadministrado (OR 1,49 IC 95% 1,03 - 2,45). A hetorogeinadade entre os estudos analisados não permite afirmar que nao há diferença estatisticamente significativa para cura e tratamento concluído. A pré-avaliação do Programa de Controle de Tuberculose possibilitou a descrição do Programa, elaboração e pactuação do modelo lógico e a matriz de relevância dos indicadores. Caracterizou-se os seus elementos estruturantes, definição de indicadores de estrutura e processo, além das perguntas avaliativas. Uma avaliação somativa com enfoque na análise dos efeitos da intervenção de controle da tuberculose é recomendada. A avaliação das características de estrutura e processo de cuidado à pessoa com tuberculose revelou melhor desempenho para as equipes de atenção básica de municípios classificados como metrópole no acesso, coordenação do cuidado e qualidade técnica da atenção. Em relação ao acesso: 98,5% acolhimento a demanda espontânea; 95,8% programação de consultas. Na coordenação do cuidado, 93,2% existência de protocolo para tuberculose. Quanto a qualidade técnica da atenção à tuberculose verifica-se que 93,4% acompanhamento de tratamento diretamente observado, 95,8% com busca ativa de faltosos ao tratamento, 64,0% oferta de ações educativas, 91,3% busca ativa de sintomáticos respiratórios. Cabe destacar que metrópoles apresentaram maior tempo médio de espera para escuta/acolhimento (24,41 minutos); para consulta previamente agendada (23,52 dias); para consulta em pneumologia (87,12 dias). Percebem-se fragilidades na estrutura e processo da atenção à tuberculose, principalmente no controle especializado da doença e na qualidade técnica entre os municípios. Recomenda-se reforço, particularmente na qualidade técnica para aumentar a cobertura de acompanhamento do tratamento, busca de sintomáticos respiratórios e das ações educativas.

Mapeamento das dissertações e teses referentes à subárea da comunicação popular, alternativa e comunitária (CPAC) desenvolvidas nos Programas de Pós-Graduação em Comunicação stricto sensu no Brasil, de 1972 a 2012. Dentre os objetivos estão localizar as pesquisas; os autores; sua distribuição no tempo e espaço; identificar as instituições e orientadores que impulsionam a subárea; definir as abordagens teórico-metodológicas; e apontar autores/conceitos referência. Por meio de pesquisa exploratória e aplicação de quatro filtros, chegou-se a uma amostra final de 102 pesquisas, 87 dissertações e 15 teses, submetidas à análise quantitativa, por meio de Análise de Conteúdo a partir de partes pré-definidas (Resumo, Palavras chave, Introdução, Sumário, Considerações Finais e capítulo metodológico, quando presente), e a uma análise qualitativa do conteúdo completo das 15 teses. O método que orienta esta pesquisa é o histórico dialético, na perspectiva da busca de uma análise de conjunto e atenta às contradições e mudanças que o objeto está implicado; e a pesquisa bibliográfica que a fundamenta se ancora em autores como Jorge González, Cicilia Peruzzo, Regina Festa, Pedro Gilberto Gomes, Gilberto Giménez e Augusto Triviños e foi realizada com o apoio do software NVivo. Resultados quantitativos indicam: a) predominância de pesquisas sobre comunicação comunitária (68%) b) predominância de estudos empíricos (79%); c) a variedade de denominações atribuídas às experiências pelos pesquisadores; d) a constante luta das classes populares por democratização da comunicação e por direitos sociais ao longo dos anos; e) a influência e importância dos intelectuais orgânicos nas experiências estudadas, f) problemas metodológicos; g) UMESP, USP e UFRJ como instituições protagonistas, e, h) Cicilia Peruzzo e Raquel Paiva como as que mais orientam teses e dissertações sobre a temática. Quanto à análise qualitativa verificaram-se alguns critérios que permeiam a CPAC: 1) a definição de classes subalternas; 2) a importância da participação ativa das comunidades nos processos de comunicação; e 3) formas, conteúdos e objetivos que se complementam e dão identidade às experiências

Preterm birth is a public health problem worldwide. It holds growing global incidence rates, high mortality rates and a risk of the long-term sequelae in the newborn. It is also poses burden on the family and society. Mothers of very low birth weight (VLBW) preterm infants may develop psychological disorders, and impaired quality of life (QoL). Factors related to mothers and children in the postpartum period may be negatively associated with the QoL of these mothers. The aim of this study was to assess factors possibly associated with the QoL of mothers of VLBW preterm newborns during the first three years after birth. Mothers of VLBW preterm answered the World Health Organization Quality of Life (WHOQOL)-bref and the Beck Depression Inventory (BDI) in five time points up to 36 months postpartum, totalizing 260 observations. The WHOQOL–bref scores were compared and correlated with sociodemographic and clinical variables of mothers and children at discharge (T0) and at six (T1), twelve (T2), 24 (T3) and 36 (T4) months after the delivery. We used the Kruskal Wallis test to compared scores across different time points and correlated WHOQOL-bref scores with the sociodemographic and clinical variables of mothers and preterm infants. Multiple linear regression models were used to evaluate the contribution of these variables for the QoL of mothers. The WHOQOL–bref scores at T1 and T2 were higher when compared to scores in T0 in the physical health dimension (p = 0.013). BDI scores were also higher at T1 and T2 than those at T0 (p = 0.027). Among the maternal variables that contributed most to the QoL of mothers, there were: at T0, stable marital union (b= 13.60; p= 0.000) on the social relationships dimension, gestational age (b= 2.38; p= 0.010) in the physical health dimension; post-hemorrhagic hydrocephalus (b= -10.05; p= 0.010; b= -12.18; p= 0.013, respectively) in the psychological dimension; at T1 and T2, Bronchopulmonary dysplasia (b= -7.41; p= 0.005) and female sex (b= 8,094; p= 0.011) in the physical health dimension and environment, respectively. At T3, family income (b= -12.75’ p= 0.001) in the environment dimension, the SNAPPE neonatal severity score (b= -0.23; p= 0.027) on the social relationships dimension; at the T4, evangelical religion (b= 8.11; p= 0.019) and post-hemorrhagic hydrocephalus (b: -18.84 p: 0.001) on the social relationships dimension. The BDI scores were negatively associated with WHOQOL scores in all dimensions and at all times points: (-1.42 ≤ b ≤ -0.36; T0, T1, T2, T3 and T4). We conclude that mothers of preterm infants VLBW tend to have a transient improvement in the physical well-being during the first postpartum year. Their quality of life seems to return to levels at discharge between two and three years after delivery. The presence of maternal depressive symptoms and diagnosis of post-hemorrhagic hydrocephalus or BDP are factors negatively associated with the QoL of mothers. Social, religious and economic variables are positively associated with the QoL of mothers of VLBW preterm.

The consumption of a product is directly linked to its quality, and are required to comply with quality standard regulations. In chicken "griller" which comes from industrial strains, selected for best growth performance, shot with up to 35 days old and weighing 1,400kg, they have not been reported in the literature a number of quality aspects This study aimed determine the muscle transformation time in the flesh in chickens "griller" incidence of meat defects, "PSE" (pale, soft and exdudative) and "DFD" (dark, firm and dry) and their correlation between different window times slaughter (total time between beginning of the fasting and the time of slaughter) and pH curve, four different times post mortem. The base data for the study was composed of information of 208 chickens, collected between August and September 2014, in a slaughterhouse slaughtering chickens in the middle region of Triangulo Mineiro and Alto Paranaíba. We used the Minitab 17.1.0 program for the development of descriptive statistical analysis and Pareto charts. The Pearson correlation was used to evaluate the linear relationship between two variables and Excel 2013, Microsoft Office®, to produce tables and graphs. The analysis consisted of 11 chickens cities and the distance to the poultry slaughterhouse ranged from 24.5 km to 123 km. It was observed that the pH curve decays gradually until time 5horas after slaughter, and its increase was 24, indicating the transformation of the muscle meat. The incidence of regular meat was 39.9%, "DFD" 30.3% and "PSE" 29.8%. For "DFD" meat, it was observed that factors: low ambient temperature, longer transportation and fast window and mileage at dirt road, contributed to its occurrence (p <0.05). For "PSE" meat, it was observed that lower body weight factors, longer transport favored frequency (p <0.05) of the meat defect. There was no significant correlation in variance analysis between distance, waiting time at rest shed and humidity related to meat defects (p> 0.05). This high incidence of defects meat may be due to pre-slaughter stress factors.

El período de descomposición del orden colonial y de trabajosa construcción de otro nuevo en clave republicana reconoce un conjunto de dispositivos y prácticas que posibilitaron el cambio político. Determinadas instituciones y agentes soportaron esta transición que supuso desmontar muchas de las antiguas referencias y modelos de acción política, y orientaron la emergencia de nuevas formas de concebir, percibir y relacionarse con el poder. En la persistencia de algunas de estas figuras clave residió la factibilidad de las nuevas repúblicas. En particular, los agentes y las jurisdicciones eclesiásticos, los ritos y celebraciones religiosas permanecieron ocupando un lugar que no puede ignorarse.

Este artículo tiene como objetivo analizar las investigaciones desarrolladas en el campo académico de la Educación Física en Argentina y Brasil basadas en la obra de Michel Foucault. Delimitaremos nuestro análisis del caso brasileño a tres pesquisadores que son, Homero Luis Alves de Lima, Alex Branco Fraga y Luiz Carlos Rigo y en el caso argentino, Ángela Aisenstein, Ricardo Crisorio y Pablo Ariel Scharagrodsky. Mostramos cómo esos trabajos están mayoritariamente referenciados en el segundo "dominio foucaultiano" y que son muy importantes para la denuncia de condiciones como la disciplinarización de los cuerpos y el control biopolítico de la población, sin embargo, el "tercer dominio" foucaultiano no es referenciado. Entendemos que ese dominio sería muy útil para la construcción de una propuesta pedagógica para la Educación Física, más allá del mero criticismo
