Evaluation of the influence of different types of seats on postural control in individuals with paraplegia

Study design: Cross-sectional study. Objectives: To assess the importance of proprioceptive and vision information on different types of wheelchair seats with regard to postural control in paraplegic individuals during static posture. Setting: Centre of Rehabilitation at the University Hospital/FMRP-USP and Rehabilitation Outpatient Clinic at University Hospital/UNICAMP, Brazil. Methods: This study involved 11 individuals with paraplegia. All individuals were submitted to an evaluation of static balance with their eyes open and closed in three different types of seats: wheelchair seat, foam seat and gel seat. Balance evaluation was performed by using the Polhemus system, in which body displacements and anteroposterior and mediolateral speeds were assessed in a static seated position in the different types of seats. Data were analyzed using analysis of variance. The differences were considered at P<0.05. Results: No statistical differences were found between the three types of seats in terms of displacements and anteroposterior and mediolateral speeds, or between seats with individuals keeping their eyes open or closed (P>0.05). However, it was observed that body displacements were more prominent toward an anteroposterior than a mediolateral direction. Conclusion: This study suggests that individuals with paraplegia tend to exhibit a more anteroposterior body displacement than a mediolateral one, with no significant differences between the types of seats in both situations of eyes open and closed.

Effects of periodontal therapy on glycemic control and inflammatory markers

Background: Periodontitis, a complication of diabetes mellitus (DM), can induce or perpetuate systemic conditions. This double-masked, placebo-controlled study evaluated the effects of periodontal therapy (scaling and root planing [SRP]) on the serum levels of glycated hemoglobin (HbA1c) and on inflammatory biomarkers. Methods: Thirty subjects with type 2 DM and periodontitis were treated with SRP + placebo (SRP; N = 15) or with SRP + doxycycline (SRP+Doxy; N = 15), 100 mg/day, for 14 days. Clinical and laboratory data were recorded at baseline and at 3 months after treatment. Results: After 3 months, the reduction in probing depth Was 0.8 mm for the SRP group (P <0.01) and 1.1 mm for the SRP+Doxy group (P <0.01) followed by a 0.9% (SRP; P = 0.17) and 1.5% (SRP+Doxy; P<0.01) reduction in HbA1c levels. A significant reduction in interleukin (IL)-6; interferon-inducible protein 10; soluble fas ligand; granulocyte colony-stimulating factor; RANTES; and IL-12 p70 serum levels were also verified (N = 30). To our knowledge, this is the first report on the effects of periodontal therapy on multiple systemic inflammatory markers in DM. Conclusions: Periodontal therapy may influence the systemic conditions of patients with type 2 DM, but no statistical difference was observed with the adjunctive systemic doxycycline therapy. Moreover, it is possible that the observed improvement in glycemic control and in the reduction of inflammatory markers could also be due to diet, which was not controlled in our study. Therefore, a confirmatory study with a larger sample size and controlled diet is necessary.

A phylogeny for the genus Isoodon and a range extension for I-obesulus peninsulae based on mtDNA control region and morphology

Short-nosed bandicoots, Isoodon, have undergone marked range contractions since European colonisation of Australia and are currently divided into many subspecies, the validity of which is debated. Discriminant function analysis of morphology and a phylogeny of Isoodon based on mtDNA control region sequences indicate a clear split between two of the three recognised species, I. macrourus and I. obesulus/auratus. However, while all previously recognised taxa within the I. obesulus/auratus group are morphologically distinct, I. auratus and I. obesulus are not phylogenetically distinct for mtDNA. The genetic divergence between I. obesulus and I. auratus (2.6%) is similar to that found among geographic isolates of the former (I. o. obesulus and I. o. peninsulae: 2.7%). Further, the divergence between geographically close populations of two different species (I. o. obesulus from Western Australia and I. a. barrowensis: 1.2%) is smaller than that among subspecies within I. auratus (I. a. barrowensis and I. auratus from northern Western Australia: 1.7%). A newly discovered population of Isoodon in the Lamb Range, far north Queensland, sympatric with a population of I. m. torosus, is shown to represent a range extension of I. o. peninsulae (350 km). It seems plausible that what is currently considered as two species, I. obesulus and I. auratus, was once one continuous species now represented by isolated populations that have diverged morphologically as a consequence of adaptation to the diverse environments that occur throughout their range. The taxonomy of these populations is discussed in relation to their morphological distinctiveness and genetic similarity.

On-line writing: a link to learning in a teacher education program

This paper examines the use of on-line discussion as a medium for learning in a pre-service teacher education program. As part of an Education Studies course student teachers engaged in a discussion of issues related to technology and equity in schools. The design of the task and the subsequent analysis of the on-line text were part of a research project investigating whether and how communications technology can be used to integrate and extend the learning of teacher education students. The main argument developed in the paper is that through the on-line activity distinctive sets of writing practices were created. These practices enabled students to make connections between the often disparate parts of teacher education programs-theory and practice, campus and school, research and experience.

Sistema de coleta on-line do Censo Escolar da Educa????o B??sica (Educacenso)

O Educacenso ?? um sistema eletr??nico de coleta de informa????es educacionais composto por um aplicativo web, que permite a coleta, migra????o e altera????o de dados educacionais das escolas em todo o territ??rio nacional, e por um banco de dados relacional, que armazena de forma sistem??tica todas estas informa????es. O Educacenso representa uma inova????o, pois se trata de um banco de dados ??nico, de base nacional, alimentado por dados e informa????es que v??m diretamente das escolas, por meio da internet. Constitui-se no mais completo cadastro de escolas, alunos e docentes do pa??s. A constru????o de um banco de dados com informa????es individualizadas amplia as possibilidades de comunica????o com outras bases de dados do governo federal. O novo desenho metodol??gico e a utiliza????o de recursos de tecnologia da informa????o permitiram ampliar a precis??o e a fidedignidade dos dados do Censo Escolar, o que possibilita realiza????o de ajustes na pol??tica educacional e maior efetividade do gasto p??blico com a educa????o b??sica

Planejamento participativo na implanta????o do sistema da concess??o on-line na Previd??ncia

Os Postos de Seguro Social do INSS processavam os dados dos segurados da Previd??ncia em lotes, acarretando demora na Concess??o de Benef??cios e perda de tempo por parte dos segurados, com muitas idas e vindas aos postos. As criticas aos dados eram realizadas uma vez por semana e em conseq????ncia os segurados eram obrigados a voltar ao posto para resolver as pend??ncias posteriormente informadas e at?? que os dados passassem pelas cr??ticas do computador central. Havia necessidade de implantar um novo sistema para melhorar o atendimento no INSS. Foi implementado no Paran?? um projeto piloto, desenvolvido pela Dataprev e a pedido de seu cliente INSS, denominado ???Concess??o de Benef??cios On Line???. Com a utiliza????o desta tecnologia, por exemplo, passou a ser poss??vel entrar com um pedido de aposentadoria e imprimir imediatamente a Carta de Concess??o, informando o valor e o banco em que ser??o feitos os pagamentos ao Segurado da Previd??ncia Social. O novo sistema ap??ia a melhoria no atendimento do segurado do INSS, porque permite informar ao Segurado imediatamente se o Benef??cio est?? concedido ou se h?? pend??ncias que devam ser atendidas
