Benefícios de um programa de educação postural para alunos de uma escola municipal de Garibaldi, RS Benefits of a posture education program for schoolchildren in the city of Garibaldi, RS

A fisioterapia tem importante papel no meio escolar, pois estudantes desenvolvem maus hábitos e alteraç��es posturais que, a longo prazo, podem gerar restrição funcional. O objetivo deste estudo foi analisar os efeitos de um programa de educação postural em estudantes do ensino fundamental da cidade de Garibaldi, RS. Participaram 48 alunos com idade entre 8 e 10 anos, que responderam um questionário sobre hábitos posturais e foram submetidos à avaliação de peso, modelo e modo de transporte da mochila antes e após uma sessão educativa; quatro semanas mais tarde foi feita uma reavaliação. Os pais participaram do estudo respondendo um questionário sobre a postura dos filhos. Quanto aos hábitos escolares, constatou-se mudança positiva na adoção de postura adequada dos pés na posição sentada (p=0,001); e, nas atividades de vida diária, mudanças na posição ao ver televisão (p<0,0001), dormir (p=0,019), pegar objetos no chão (p<0,0001) e costume de ler e/ou escrever na cama (p=0,002). Em relação ao peso da mochila obteve-se redução significativa após a intervenção (p=0,002), enquanto no modelo e modo de transporte não houve diferença. Segundo os pais, os filhos têm bons hábitos de postura e costumam utilizá-los no dia-a-dia. Concluiu-se que a realização de uma sessão de educação postural para alunos promoveu o conhecimento de hábitos posturais saudáveis e modificação de algumas posturas, mas não se pode afirmar que provocou mudanças nos hábitos posturais.<br>Physical therapy plays an important role in school, as students develop bad habits and postural dysfunctions which may generate long-term functional restrictions. The aim of this study was to analyse the effects of an educational program on students' posture in Garibaldi, RS. Forty-eight 8-to-10 year-old schoolchildren filled up a questionnaire about postural habits and had their knapsacks assessed as to weight, type and carrying mode, before and after an educational session; a further assessment was made four weeks later. Parents participated by answering a questionnaire on children's posture. Results showed positive changes in feet posture in the sitting position (p=0.001); in daily living activities, better postures or habits were found while watching television (p<0.0001), sleeping (p=0.019), getting objects from the ground (p<0.0001), and reading and/or writing in bed (p=0.002). As to knapsack weight, a significant decrease (p=0,002) was noticed after the session, while neither the model or mode of transport changed. Parents answered that their children have good postural habits and keep them on a regular basis. It may thus be said that one session of postural educational program for schoolchildren resulted in better knowledge on healthy postural behaviour and modified some postures, but one can't say it brought about changes in postural habits

Caffeic Acid Detection Using an Inhibition-Based Lipoxygenase Sensor

WOS: 000303448100008An inhibition based biosensing system was developed for the caffeic acid as lipoxygenase (LOX) inhibitor. LOX was immobilized in carbon paste electrode and the amperometric detection of hydroperoxy linoleic acid due to the enzymatic reaction using linoleic acid as a substrate was monitored at +0.9 V versus Ag/AgCl. The decrease in biosensor response in the presence of caffeic acid was found to be correlated with the inhibitor concentration. Diode array detector and LOX biosensor was used as an electrochemical detector for the analysis of this compound. All data were given as a comparison of two systems.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [2209]TUBITAK is acknowledged for financial support (2209-research project supports for university students)

Can chest high-resolution computed tomography findings diagnose pulmonary alveolar microlithiasis?

AbstractObjective:The present study was aimed at retrospectively reviewing high-resolution computed tomography (HRCT) findings in patients with pulmonary alveolar microlithiasis in order to evaluate the frequency of tomographic findings and their distribution in the lung parenchyma.Materials and Methods:Thirteen patients (9 females and 4 males; age, 9 to 59 years; mean age, 34.5 years) were included in the present study. The HRCT images were independently evaluated by two observers whose decisions were made by consensus. The inclusion criterion was the presence of abnormalities typical of pulmonary alveolar microlithiasis at HRCT, which precludes lung biopsy. However, in 6 cases lung biopsy was performed.Results:Ground-glass opacities and small parenchymal nodules were the predominant tomographic findings, present in 100% of cases, followed by small subpleural nodules (92.3%), subpleural cysts (84.6%), subpleural linear calcifications (69.2%), crazy-paving pattern (69.2%), fissure nodularity (53.8%), calcification along interlobular septa (46.2%) and dense consolidation (46.2%).Conclusion:As regards distribution of the lesions, there was preferential involvement of the lower third of the lungs. No predominance of distribution in axial and anteroposterior directions was observed
