Prevalência e fatores associados à respiração oral em escolares participantes do projeto Santo Amaro-Recife,2005

Abstract: OBJETIVO: Determinar prevalencia de criancas portadoras de respiracao oral inscritas no Projeto Santo Amaro/ ESEF/ UPE e verificar as principais alteracoes faciais e comportamentais associadas. FORMA DE ESTUDO: Estudo transversal. MATERIAL E METODO: Amostra de 150 criancas de 8 a 10 anos. Dados coletados mediante aplicacao de questionario e exames clinicos. Para o diagnostico da respiracao foram feitos dois testes. Teste 1, observado no espelho, vapor decorrente da respiracao, e teste 2, a permanencia de agua na boca com os labios em contato pelo tempo de 3 minutos. RESULTADOS: Prevalencia de respiracao oral foi de 53,3%. Nao se comprovou diferenca significante entre genero, faixa etaria, tipo de respiracao. As alteracoes faciais da respiracao oral foram: selamento labial inadequado (58,8% x 5,7%), olhos caidos (40,0% x 1,4%), palato ogival (38,8% x 2,9%), mordida aberta anterior (60,0% x 30,0%), labios hipotonicos (23,8% x 0,0%) e olheiras (97,5% x 77,1%). CONCLUSAO: Prevalencia de respiracao oral elevada sem diferenca estatistica entre os generos, faixa etaria e tipo de respiracao oral. Nao houve associacao entre caracteristicas comportamentais e o tipo de respiracao. Houve diferenca significante entre as caracteristicas fisicas e o padrao de respiracao.

Is it better to be rich in a poor area or poor in a rich area? A multilevel analysis of a case–control study of social determinants of tuberculosis

Abstract: Background Tuberculosis is known to have socio-economic determinants at individual and at area levels, but it is not known whether they are independent, whether they interact and their relative contributions to the burden of tuberculosis. Methods A case–control study was conducted in Recife, Brazil, to investigate individual and area social determinants of tuberculosis, to explore the relationship between determinants at the two levels and to calculate their relative contribution to the burden of tuberculosis. It included 1452 cases of tuberculosis diagnosed by the tuberculosis services and 5808 controls selected at random from questionnaires completed for the demographic census. Exhaustive information on social factors was collected from cases, using the questionnaire used in the census. Socio-economic information for areas was downloaded from the census. Multilevel logistic regression investigated individual and area effects. Results There was a marked and independent influence of social variables on the risk of tuberculosis, both at individual and area levels. At individual level, being aged ≥20, being male, being illiterate, not working in the previous 7 days and possessing few goods, all increased the risk of tuberculosis. At area level, living in an area with many illiterate people and where few households own a computer also increased this risk; individual and area levels did not appear to interact. Twice as many cases were attributable to social variables at individual level than at area level. Conclusions Although individual characteristics are the main contributor to the risk of tuberculosis, contextual characteristics make a substantial independent contribution.

Open Source Cloud Computing Platforms

Abstract: With the popularization of cloud computing, several enterprises and open-source communities have developed their own cloud solutions. A number of factors weigh on user selection, as each one has peculiar characteristics and may target different usage scenarios. Considering such challenge, this paper focuses on giving the reader an understanding of some major existing open cloud computing solutions – XCP, Eucalyptus and Open Nebula. Hopefully, a deep comparison of such solutions can leverage the cloud computing research area providing a good starting point to research groups and interested readers.

Risk factors for mediastinitis after coronary artery bypass grafting surgery

Abstract: OBJECTIVE: Mediastinitis is a serious complication of median sternotomy and is associated to significant morbidity and mortality. The aim of this study is to identify risk factors for mediastinitis in patients undergoing coronary artery bypass grafting (CABG), without the use of bilateral internal thoracic artery (ITA), at the Division of Cardiovascular Surgery of Pronto Socorro Cardiologico de Pernambuco - PROCAPE. METHODS: A retrospective study of 500 consecutive patients operated on between May 2007 and April 2010. Ten preoperative variables, seven intraoperative variables and seven postoperative variables possibly involved in the development of postoperative mediastinitis were evaluated. Univariate and multivariate logistic regression analyses were performed. RESULTS: The incidence of mediastinitis was 5.6% (n=28), with a lethality rate of 32.1% (n=9). In multivariate analysis using logistic regression, five variables remained as independent risk factors: obesity (OR 2.60, 95% CI 1.11 to 6.68), diabetes (OR 2.71, 95% CI 1.18 to 6.65), smoking (OR 2.10, 95% CI 1.12 to 4.67), use of pedicled internal thoracic artery (OR 5.17, 95% CI 1.45 to 18.42) and on-pump CABG (OR 2.26, 95% CI 1.14 to 5.85). CONCLUSION: This study identified the following independent risk factors for mediastinitis after CABG: obesity, diabetes, smoking, use of pedicled ITA and on-pump CABG.
