Prevalência e fatores associados à prática de esportes individuais e coletivos em adolescentes pertencentes a uma coorte de nascimentos

O presente estudo investigou a prática de esportes individuais e coletivos e fatores associados em jovens com idade média de 11 anos, pertencentes a uma coorte de nascimentos. Informações dos jovens e de suas mães foram coletadas por meio de questionários. O desfecho foi dividido em prática de esportes individuais e coletivos. Uma análise por meio de regressão de Poisson foi conduzida para estabelecer os fatores associados à prática esportiva, obedecendo a um modelo conceitual de análise com as variáveis independentes hierarquizadas. Um total de 4350 jovens foi estudado. A prática de esportes coletivos foi menor nas meninas - 68,1% (IC95% 66,2 - 70,0) em comparação aos meninos - 82,1% (IC95% 80,5 - 83,7). Nos esportes individuais, a prevalência foi de 12,9% (IC95% 11,6 - 14,4) e 18,9% (IC95% 17,3 - 20,6) em meninas e meninos, respectivamente. Entre as meninas, a prática de esportes individuais relacionou-se diretamente com nível econômico e inversamente com assistir televisão. Nos meninos este desfecho associou-se com estudar em escolas privadas e ter mães fisicamente ativas. Em esportes coletivos, a prática foi menor naqueles que despendem maior tempo assistindo TV. Em ambos os sexos houve uma relação direta entre o uso regular do vídeo-game e a prática de esportes. Políticas públicas devem considerar os diferentes aspectos relacionados à prática esportiva e atender a disparidades socioeconômicas no acesso a diferentes modalidades esportivas. Além disso, o maior acesso a diferentes locais de práticas esportivas, bem como o incentivos de pais, amigos e ambiente escolar devem ser fortalecidos.The present study investigated individual and collective sports practice and associated factors among adolescents with a mean age of 11 years, belonging to a birth cohort study. Information on the adolescents and on their mothers were obtained through questionnaires. The outcome variable was divided into practice of individual and collective sports. Poisson regression models were used in order to determine the factors associated with sports practice, following a hierarchical framework. A total of 4350 adolescents were interviewed. Practice of collective sports was less frequent among girls - 68.1% (95%CI 66.2 - 70.0) in comparison to boys- 82.1% (95%CI 80.5 - 83.7). Regarding individual sports, the prevalence was 12.9% (95%CI 11.6 - 14.4) and 18.9% (95%CI 17.3 - 20.6) in girls and boys, respectively. Among girls, individual sports practice was directly associated with socioeconomic level and inversely with television viewing. Among boys, the outcome was associated with studying in private schools and having an active mother. In terms of collective sports, the practice was less frequent among those with high level of television viewing. In both sexes, a direct association was observed between videogame playing and sports practice. Public policies should consider the different aspects related to sports practice and consider socioeconomic inequalities in sports practice

Primary biventricular repair of atrioventricular septal defects: an analysis of reoperations

BackgroundThe purpose of this study was to analyze the factors affecting reoperation after primary biventricular atrioventricular septal defect (AVSD) repair.MethodsBetween April 1997 and April 2007, 93 consecutive patients underwent surgery for biventricular correction of AVSD with a median age of 5.8 months (range, 9 days to 68.9 years). Fifty-three patients had complete AVSD, 6 patients had an intermediate type, and 29 patients had partial AVSD; 4 patients had a complete AVSD with associated tetralogy of Fallot, and 1 patient had a complete AVSD with double-outlet right ventricle.ResultsThere was no in-hospital mortality. There were 2 late deaths (2.2%). Forty-three reoperations were performed in 23 patients (24.7%), of which 18 were for repair of significant left atrioventricular valve regurgitation and 8 were mitral valve replacements. Seven patients (7.5%) required insertion of a permanent pacemaker. The overall 5-year freedom from reoperation after AVSD repair was 73.6% ± 4.8%. In the multivariate analysis for complete AVSDs, Down syndrome (p = 0.01) and the presence of right ventricular dominance (p = 0.03) were independent predictors of reoperation. At last follow-up, 76 patients (83.5%) were in New York Heart Association class I, and 68 patients (74.7%) were not taking any heart failure medications. Echocardiographic examination showed absent to mild left atrioventricular valve regurgitation in 76.5%; moderate, in 19.8%; and severe, in 3.7% of patients.ConclusionsDown syndrome and right ventricular dominance are independent predictors of reoperation after complete AVSD repair. Biventricular repair of isolated AVSD with a small left ventricle can be successfully accomplished with no mortality.<br/

Composição em ácidos graxos da gordura na carcaça de frangos de corte sob dietas com diferentes fontes de energia Carcass fatty acid composition of broiler fed different sources of energy

Avaliaram-se os níveis de energia metabolizável normalmente utilizados nas rações de frangos de corte, obtidos pela inclusão de óleos vegetais (soja, canola e palma) e seus efeitos sobre o perfil de ácidos graxos da pele e dos músculos da coxa e do peito, levando-se em consideração a linhagem e o sexo. Foram utilizados 2400 pintos de um dia, machos e fêmeas, das linhagens comerciais Hubbard e Avian Farms. As aves receberam ração inicial e final com níveis de energia metabolizável de 3050 e 3150kcal/kg, respectivamente, obtidos pela inclusão dos óleos vegetais, fornecedores de ácidos graxos, inclusive "ômega-3". Utilizou-se um delineamento inteiramente ao acaso em um arranjo fatorial com 16 tratamentos (4 rações × 2 sexos × 2 linhagens) com duas repetições cada. Diferenças entre médias foram testadas pela dms. Não houve efeito significativo da inclusão de óleos na ração sobre o perfil de ácidos graxos na carcaça. O mesmo ocorreu quanto ao efeito de sexo e de linhagem.<br>An experiment was carried out with the objective of evaluating the effect of metabolizable energy levels, normally utilized in ration for broilers by addition of vegetable oils (soybean, rapeseed, and palm), on the profiles of fatty acids of the skin and meat of breast and thigh according sex and lineage, based on 2,400 one-day-old chicks, males and females, from Hubbard and Avian Farms. The fowls were given initial and finisher rations with metabolizable energy levels of 3,050 and 3,150kcal/kg, respectively, obtained by the inclusion of vegetable oils, which provided fatty acids, including "omega-3". The initial and finisher control rations were based on corn and soybean, without oil inclusion, with metabolizable energy levels of 2,900 and 3,000, respectively. A completely randomized design with factorial arrangement (4 rations × 2 sexes × 2 lines) and SMD test were used. No effects of sex, lineage and oil inclusion on carcass fatty acid profiles were observed

Narrowing the critical region within 11q24-qter for hypoplastic left heart and identification of a candidate gene, JAM3, expressed during cardiogenesis

Hypoplastic left heart is a severe human congenital heart defect characterized by left ventricular hypoplasiawith aortic and mitral valve atresia. A genetic etiology is indicated by an association of the hypoplastic left heart phenotype with terminal 11q deletions that span approximately 20 Mb (distal to FRA11B in 11q23). Here we define the breakpoints in four patients with heart defects in association with distal 11q monosomy and refine the critical region to an approximately 9-Mb region distal to D11S1351. Within this critical region we have identified JAM3, a member of the junction adhesion molecule family, as a strong candidate gene for the cardiac phenotype on the basis that it is expressed during human cardiogenesis in the structures principally affected in hypoplastic left heart

Focus sur les déclencheurs de l’évolution des actions d’accompagnement pédagogique

Les déclencheurs du processus d’innovation s’enracinent dans des impositions institutionnelles, des sollicitations d’enseignants, des demandes d’étudiants, dans l’observation de dysfonctionnements ou encore dans le seul désir d’innover par rapport à des pratiques devenues routinières. La conception d’une nouvelle action d’accompagnement pédagogique tient compte de nombreux éléments de contextualisation et peut être alimentée, en fonction du statut, du parcours et de la professionnalisation de l’accompagnateur, tant par les apports de recherches récentes dans différents domaines que par des échanges de pratiques entre collègues. Enfin, la mise en œuvre d’une action mène à une démarche cyclique d’évaluation et de régulation, amenant un éclairage nouveau sur les déclencheurs initiaux de l’innovation et un éventuel processus de réajustement des modalités d’action. Ce processus d’innovation en trois étapes est présenté et illustré par trois actions mises en place dans différents contextes d’enseignement en Communauté française de Belgique.info:eu-repo/semantics/publishe
