Atendimento ambulatorial versus programa de educação infantil : qual oferece mais mudança de hábito?

De acordo com um recente relatório da Organização Mundial de Saúde, a obesidade atingiu proporções epidêmicas em todo o mundo. Hoje a obesidade é muito comum e está começando a substituir a desnutrição e as doenças infecciosas. A obesidade está relacionada com doenças crônico-degenerativas e com sérias conseqüências psicológicas para o indivíduo. A obesidade é uma doença complexa e heterogênea, influenciada por diversos genes, no entanto, a combinação dos genes envolvidos no desenvolvimento de formas de obesidade ainda não foi definitivamente determinada (REILLY et al, 2002). A obesidade, ou o aumento da adiposidade, é geralmente atribuída a um desequilíbrio entre a energia ingerida (padrão alimentar) e a energia gasta (atividade física e metabolismo basal). Assim, o manejo da obesidade consiste em tornar esse balanço energético negativo, sendo o exercício considerado um dos aspectos principais, associado com mudanças alimentares e de estilo de vida saudáveis (ESCRIVÃO & LOPEZ, 1998). Dietas são, na maioria das vezes, transitórias. Então, a mudança de hábito alimentar e de atividade física são os aspectos principais, especialmente na criança, uma vez que a manutenção de peso irá proporcionar uma melhora dramática da composição corporal, já que o crescimento linear ainda existe. Mas, qualquer mudança de hábito necessita da colaboração da família (HILL et al, 1993). Assim, o presente estudo teve como objetivo principal comparar um programa de educação em obesidade infantil com o atendimento ambulatorial para manejo de obesidade infantil quanto a mudanças de hábitos alimentares e de atividade física e aquisição de conhecimentos em dieta saudável. Foi desenvolvido inicialmente um programa de educação em obesidade infantil e posteriormente comparado com o atendimento ambulatorial habitual. O presente estudo constou de um ensaio clínico randomizado entre crianças e adolescentes com idade entre 7 e 13 anos incompletos que tivessem IMC compatível para obesidade, de acordo com a idade e sexo, segundo classificação de COLE et al (2002). Os sujeitos foram aleatoriamente distribuídos em dois grupos. Cada grupo foi acompanhado por oito meses, sendo que o primeiro e o oitavo encontro serviram para responder questionários que avaliavam aspectos gerais, hábitos alimentares e de atividade física, conhecimentos gerais sobre dieta saudável e avaliação corporal. O grupo ambulatorial teve atendimento mensal com aferição de peso e orientações gerais quanto alimentação e atividade física. O grupo programa tinha encontro mensal, em grupo, seus participantes assistiam a uma aula expositiva e, posteriormente, eram divididos em grupos para atividades monitoradas, e os pais e/ou responsáveis ficavam discutindo suas dificuldades e como mudar hábitos. As 38 crianças inicialmente apresentavam algumas diferenças quanto a atividade física, mas após a intervenção elas se assemelharam, apresentando ambas tendência a desfechos favoráveis. O grupo programa passou a fazer mais atividade física e caminhar, e reduziu sedentarismo. O grupo programa foi mais efetivo em reduzir colesterol total. Houve também uma melhora do hábito alimentar do grupo programa, com menor consumo de massa + arroz, bebida láctea + leite, leite, salsicha + frios e sanduíche + bauru. Assim, conclui-se que as intervenções foram semelhantes e de sucesso, podendo-se aplicar mais o programa, que pode envolver menos profissionais, mais sujeitos e ser realizado em qualquer local, especialmente nas escolas, que são, na realidade, o local de mudança.

Avaliação do extrato do fungo caripia montagnei e de agonistas de PPAR - α no processo inflamatório

The mushrooms have been object of intense research in view of its potential raising of application in different sectors of the pharmacology and alimentary industry. Among diverse bioactive composites of polyssacharides nature that exist in the fungus the glucans are much searched. These are polymers of glucose and classified as the type of glicosidic linking [α, β]. Peroxisome proliferator-activated receptors (PPARs), ranscription factors belonging to the family of nuclear receptors that bind themselves o specific agonists, have shown their importance in controlling the inflammatory process. The aim of this study was to perform a chemical characterization of extract rom the mushroom Caripia montagnei, assess its antiinflammatory and antibacterial effect and determine if this effect occurs via PPAR. This mushroom is composed of carbohydrates (63.3±4.1%), lipids (21.4l±0.9%) and proteins (2.2± 0.3%). The aqueous solution resulting from the fractionation contained carbohydrates (98.7±3.3%) and protein (1.3±0.25%). Analyses of infrared spectrophotometry and of nuclear magnetic esonance demonstrated that the extract of mushroom C. montagnei is rich in β-glucans. In hioglycolate-induced peritonitis, the C. montagnei glucans (50 mg/kg) educed the inflammatory process in 65.5±5.2% and agonists, pharmacological igands, for PPAR: Wy-14643 (49.3±6.1%), PFOA (48.9±3.8%) and clofibrate in 45.2±3.2%. Sodium diclofenac showed a reduction of 81.65±0.6%. In the plantar edema, the glucans from C. montagnei (50 mg/kg) and L-NAME reduced the edema to a similar degree 91.4±0.3% and 92.8±0,5 %, respectively. In all the groups tested, nitric oxide (NO), an inflammation mediator, showed a significant reduction in the nitrate/nitrite levels when compared to the positive control (P<0.001). The C. montagnei glucans did not show cytotoxicity in the concentrations tested (2.5, 5.0, 10.0, 20.0 and 40.0 µg/100 µL). Antibacterial activity demonstrated that, unlike total extract, there was no inhibition of bacterial growth. The C. montagnei glucans show great potential for antiinflammatory applications. This effect suggests that it is mediated by PPAR activation and by COX and iNOS inhibition

Avaliação das concentrações hepáticas e séricas de retinol em bovinos e do consumo habitual de fígado por gestantes

The vitamin A is essential to animals because of its participation in a great number of biological functions. The investigation of this vitamin s concentrations is important to serve as reference to normality parameters. This study had as aim to analyse the serics and hepatics concentrations of vitamin A in two groups of bovines and to compare the hepatics concentrations to the present requeriments of vitamin A for pregnant women. It was also appraised the consume habit of bovine liver by pregnant women through of the alimentary frequency quest. Two groups of bovine were studied and the first was formad by Nelore bovine breed and the second by bovine without defined breed (WDB). It was analysed 120 samples: 60 of liver and 60 of serum. The method used to dose retinol was High Performance Liquid Cromatography (HPLC). The average (+ sd) of retinol concentrations in Nelore breed bovine and WDB liver were 16947,8 + 6866,9 and 5213,1 + 2517,2 µg of retinol/100g and at serum 39,6 + 17,9 e 28,6 + 9,4 µg of retinol/dL, respectively. No statistically significant correlation was found between hepatic and the serum retinol. The bovines in this study had adequate vitamin A levels. Independently of animal breed, the daily ingestion of bovine liver is not advised for pregnant women who show adequate support of vitamin A. The consume of bovine liver by pregnant women consulted on school maternity hospital Januário Cicco, UFRN, Natal RN, was considered high

Avaliação do efeito da megadose de vitamina A no colostro humano

The mothers supplementation of vitamin A in the postpartum comes being a measure of intervention sufficiently used in the combat to the vitamin deficiency. The objective of this work was to evaluate the effect of the mother megadose of vitamin A under the levels of retinol in colostrum of postpartum mothers receiving care at the Januário Cicco Maternity School (MEJC), Natal, RN, as well as analyzing the influence of the maternal nutritional status in the reply to this supplementation. The study it was transversal type, with participation of 91 women in labor divided in group had participated of the study have controlled (44 women) and supplemented group (47 women). In the period of the morning blood and milk had been collected (milk 0h). After that a capsule of retinil palmitate of (200 000 UI or 60 mg) was supplied to the supplemented group. Another aliquot of colostro was after gotten 24h of the first collection (milk 24h). Retinol in milk and serum was quantified through the High Pressure Liquid Chromatography. The vitamin ingestion was evaluated by the questionnaire of frequency of alimentary consumption. The levels of serum retinol were 40.6 ± 10.6 and 35.9 ± 10.9 µg/dL in the groups controlled and supplemented, respectively. The women had presented a satisfactory average ingestion of vitamin (1492,4 µgRAE/dia), however with high prevalence of inadequate consumption (23%). Average values of retinol in milk 0h had been found and 24h of 93.5 ± 50.3 µg/dL and 99.1 ± 49.3 µg/dL has the group controlled group, respectively (p>0.05). After the supplementation had a significant increase in the levels of retinol of the supplemented group, being found values of 102.0 ± 56.0 µg/dL and 196.1 ± 74.0 µg/dL for milk 0h and 24h, respectively (p<0.0001). The women in labor presented different answers to the supplementation influenced for the basal levels of retinol in colostrum. It was possible to verify that women with deficient levels of retinol in milk had transferred more retinol to milk 24h than ones with adjusted levels, showing a percentage of reply equivalent to 326.1% and 86.5% of increase, respectively (p< 0.0001). Although the apparent normality found in the serum, the studied women are considered of risk to the development of the vitamin deficiency, and megadose was efficient in first 24h after the supplementation and wakes up with the mechanisms considered for transference of vitamin A to the milk

Brachyuran soft-bottom assemblage from marine shallow waters in the southeastern Brazilian littoral.

The present investigation examined the assemblages of brachyuran crabs in three bays of southeastern So Paulo State, analyzing the numbers of species and individuals, biomass, and diversity. The crabs were collected monthly in Ubatumirim, Ubatuba, and Mar Virado bays in the Ubatuba region over 2 years (1998 and 1999). In each bay, six tows were made from a fishing boat. A total of 39,820 specimens, representing 11 super families, 39 genera, and 65 species of brachyurans, were obtained. The mean number of specimens and biomass varied seasonally, which can be mainly related with the population tendencies of two dominant species in the area (Callinectes ornatus and Hepatus pudibundus). The highest numbers of individuals and species were found in Ubatuba Bay, followed by Ubatumirim and Mar Virado. The highest diversity index was estimated for Ubatumirim (H' = 2.44), followed by Ubatuba (H' = 2.37) and Mar Virado (H' = 1.86). In general, the coastal region supported high abundance and species richness concerning brachyurans, with high diversity indices, probably because of its more-heterogeneous substrate, which may afford more refuges for certain species. These results suggested that environmental conditions in this area, although they showed certain differences, are favorable for the establishment and development of a diverse brachyuran guild.

Desvendando o padrão alimentar de famílias rurais: o que tem no prato?

That work looked for to point out the different conceptions on the family agriculture and the established self-consumption practices inside the unit of production. Hypothesis: due to the conditions, more and more restricted of producing for the self-consumption, the rural families are more favorable present her situation of alimentary insecurity as severe as for the urban families, unlike what he/she defends. The research was accomplished in three states of the Northeast: Paraíba; Rio Grande do Norte and Sergipe. The results revealed that among the main factors that expose those families to situations of constant alimentary vulnerability are had: the low quality of the alimentary consumption in what concerns the readiness, to the diversification and mainly, to the accessibility. The analyses can be to subsidize a reflection concerning the alimentary pattern of families rural front to the precepts of Food and Nutrition Security (FNS) politics

Maracatus Solar e Reis de Paus: tradição e modernidade no carnaval de rua em Fortaleza

This is an ethnographic and comparative study of the Maracatus Solar (2006) and Reis de Paus (1960), whose aim was to verify what is ancient and traditional in the new maracatu practiced by the guild Solar and conversely, what is new or modern in the old maracatu ritualized by guild Reis de Paus. It is worth noting that through this case study it is also intended to ethnographically observe and better understand the processes of ruptures and continuities between modernization and tradition, and the relationship between the global and the local. The communication system, the dancing, the music, the costumes and the loas (letters) were analyzed using the technique of participant observation as well as secondary materials such as newspapers, blogs and magazines. The interviews were open, non-directive, but recorded to facilitate understanding the speech of revelers. The research has shown that all the symbolic elements of aesthetic expression of the maracatu are permeated by clashes of historical contexts and of political representation, which, in another instance, also enunciates a fight of micro-community resistance regarding the renewal process and the social development that plague modern megalopolis. It is In this interim, between modernity and tradition that today it can be spoken about the existence of hybrid identity in the maracatu regarding a context mediated by the overall above mentioned values and customs specific of the new generations. However, one can not deny that the forms of negotiations with modernity also require the establishment of a link with the specific singularity of a popular culture that is not excluded, but also should not get invaded by the idea of authenticity. Therefore, performing this study was above all an opportunity to understand also the community life in the city outskirts, understanding society, culture and everyday social relations maintained between humans that produce and make it all happen. The Solar and Reis de Paus do not join in opposition between themselves nor by their similarity. What is most striking among them is the renewal of a tradition that reinvents itself in the form of popular representation across the street parade

Generalized systemic cryptococcosis in a dog after immunosuppressive corticotherapy

Um cão da raça Boxer, macho, com 2 anos e 11 meses de idade foi encaminhado ao hospital veterinário com histórico de distúrbio gastroentérico de dois meses de duração, apatia, hiporexia, emagrecimento progressivo e deficiência visual. Ataxia e vocalização foram observadas posteriormente. O animal estava sendo tratado em outra clínica veterinária com antibióticos e doses imunossupressoras de corticóides, direcionados ao controle de provável enterite alimentar. A morte ocorreu após cinco dias. As observações macro e microscópica revelaram tratar-se de criptococose sistêmica, atingindo trato digestório, olhos, SNC, rins, pâncreas e linfonodos. O presente relato enfatiza a infecção fúngica criptocócica quanto aos seus aspectos grastrointestinais iniciais a serem considerados no diagnóstico clínico, ressaltando a imunossupressão induzida pela corticoterapia.

Biodigestão anaeróbia de dejetos de caprinos obtidos nas diferentes estações do ano

Foram utilizados dejetos produzidos por caprinos, em diferentes estádios fisiológicos e submetidos ao mesmo regime alimentar, nas quatro estações do ano. O objetivo foi avaliar o efeito das estações do ano sobre a digestão anaeróbia de resíduos de caprinos em biodigestores modelo batelada com volume útil de 60 L de substrato em fermentação e mantidos sob temperatura ambiente. Foram avaliadas as produções de biogás, as reduções de sólidos voláteis (SV), os potenciais de produção (m³ de biogás/kg de substrato, de estrume, de sólidos totais (ST) ou sólidos voláteis), os números mais prováveis de coliformes totais e fecais, e a composição do biogás. As reduções de SV foram de 38; 34; 33 e 39% para o verão, outono, inverno e primavera, respectivamente. Os totais de biogás produzidos foram de 1,06 m³ no verão, 0,88 m³ no outono, 0,88 m³ no inverno e 0,99 m³ na primavera, e os potenciais de produção médios foram de 0,02 m³ de biogás/kg de substrato e 0,2 m³ de biogás/kg de estrume para todas as estações. As reduções médias de coliformes totais e fecais foram de 99,99% em todas as estações, e os teores máximos de CH4 no biogás foram 88,3; 84,6; 80,6 e 79,2%, para o verão, outono, inverno e primavera, respectivamente.

Efeito de cultivares de algodoeiro sobre a biologia e capacidade predatória de Orius Insidiosus (say, 1832) (hemiptera: anthocoridae) predando Aphis Gossypii Glover, 1877 (Hemiptera: Aphididae)

The objective of this research was to determine the survival, reproduction and predaceous capacity of Orius insidiosus on cotton aphid Aphis gossypii. Cotton plants of Antares, CNPA7H and Acala 90 cultivars (respectively, without tricome, medium tricome density and high tricome density) were individualized and infested with 15 third/fourth instar nymphs of A. gossypii, and then first-instar nymphs of O. insidiosus were released on the plants. The evaluations were made daily, quantifying survival and nymphal development; the number of cotton aphids A. gossypii per day and total; the number of eggs and the population of the predator (number of insects by female); and the conversion efficiency of A. gossypii predaceous. The nymphal development did not differ according to the cotton cultivars. The Antares cultivar favored a higher daily predation rate for the 1st, 2nd and 4th instars and adults of O. insidiosus. The number of eggs and nymphs was smaller when O. insidiosus females were confined on the Acala 90 cultivar. According to the predation rate of O. insidiosus, the efficiency of alimentary conversion was determined for the Antares, CNPA7H and Acala 90 cultivars, being respectively, 4.28, 3.00 and 2.75 cotton aphid predation for each egg of the predator.

As coisas estão no (meu) mundo, só que eu preciso aprender. Autobiografia, reflexividade e formação em Educação Nutricional

This paper gives clues for the educative action in nutrition subjects. It deals about the professors experiences deployments lived in 2003 e 2004, both in Nutrition undergraduate course of the Federal University of the Rio Grande do Norte (UFRN), in Nutrition Education and Supervised Internship in Social Nutrition academic disciplines, as well as in the II Update Course in Nutrition Practices for Health Basic Care , offered to the supervisors nutritionists of internship, in this same department, being able to be characterized as an action-research, with interventionism purpose. The study stands out the importance of a new point of view about the nutritionist formation to overcome the limits imposed by the scientism, and the adoption of a complex and reflexive reference about the educational practice in this area. The corpus is made up by 81 undergraduate students alimentary autobiography (source of generating subjects for interventions with the nutritionists), 17 questionnaires and 05 interviews, being 03 of them biography (the start up for an initial dialogue with the nutritionists). The data found and the professors experiences allied to a theoretic reference, by the light of the education proposals for the XXI century were used as establishment elements for the proposition of five guidance axles used to build a complex and reflexive nutrition education, which are: 1) Take the cookery and the culture of eating together as significant elements for the human being integral formation; 2) Conceive the religion manifestations associated to feeding process as relevant elements of the human food culture; 3) Discuss the rupture nature/culture aiming the preservation of live in earth; 4) Search for the overcoming of the identity conflicts by a higher inclosing conscience degrees of being part of this process. 5) Face the limits of fragmented formation. The presented thesis stands that the autobiography method, allied to the freirean pedagogy and to a complex reference, could be taken as an important tool to the health educative subjects, contributing to the formation of reflective individuals able to transform themselves and the world.

Gestão ambiental e competitividade: um estudo sobre os fatores que afetam a decisão de compra de produtos orgânicos na cidade de Teresina-PI

The organic products represent one of the main trends of alimentary consumption in the new century. In Brazil, the answer is already well representative which it becomes the country, as a great consuming and exporting market of products of LVF type. The objective of this research was to investigate the factors capable to influence the food consumer in its purchase decision of organic products in the supermarkets of Teresina, capital of Piauí State. The methodology was exploratory and descriptive, using survey, with closed and opened questions in 542 interviewed. The questionnaire was based on projected scales to evaluate the factors that can influence the purchase decision of organic products, whose variable had been grouped in the following groups: behavior, knowledge, interest, competitiveness, importance, barrier and profile. The used statistical techniques were descriptive analysis and multiple regression analysis. The results demonstrate interest of the population in paying more for the organic product, due to better quality of life, however it lacks to one better spreading and greater sensitization to attract these consumers. Some recommendations and proposals are presented after the results, as suggestions for future research

Tecnologia mais limpa para produção de mel seco de cana e sua inclusão em rações de frangos de corte

This study analyzed the effects of adding dry sugar cane molasses (MSC) to the feed of broiler chickens, and determining the economic feasibility of use of this type of diet; 240 male Ross race broiler chickens, one day in age, were utilized in this study. The experimental desing was a completely randomized whit 6 treatments and 4 replications, in 24 portions of 10 birds per parcel. The treatments corresponded to 6 rations (T1-T6) in phase initial (1-21 days) and 6 rations (T1-T6) in phasem finish (22-42 days) characterized by substitution of corn meal in levels increase 0, 5, 10, 15, 20 e 25% by the molasse dried sugar-cane. The birds received water and free ration during the whole creation phase, being the iso-proteins and iso-calories rations. The variance analysis showed the 1 a 21 days significant differences for average gain weight (P<0,05), average consumption of ration (P<0,05) and average alimentary conversion (P<0,05) and the 22 a 42 days, the analysis of variance showed significant differences for gain in weight (P<0,01) and average alimentary conversion (P<0,05). There no difference significant on average consumption of ration (P>0,05) the 22 a 42 days of age. Results showed out that is possible to use molasse dried sugar-cane up to 8,3 % in broilers ration. It was concluded the level of 8,3 % of addition gave the best economical returns in the experimental conditions
