Frequency of participation of 8-12 year old children with cerebral palsy: a multi-centre cross sectional European study

Participation in home, school and community is important for all children; and little is known about the frequency of participation of disabled children. Frequency of participation is a valuable outcome measure for evaluating habilitation programmes for disabled children and for planning social and health services.

We investigated how frequency of participation varied between children with cerebral palsy and the general population; and examined variation across countries to understand better how the environmental factors such as legislation, public attitudes and regulation in different countries might influence participation.

We undertook a multi-centre, population-based study in children with and without cerebral palsy. Working from the Life-H instrument, we developed a questionnaire to capture frequency of participation in 8–12-year-old children. In nine regions of seven European countries, parents of 813 children with cerebral palsy and 2939 children from the general populations completed the questionnaire.

Frequency of participation for each question was dichotomised about the median; multivariable logistic regressions were carried out.

In the general population, frequency of participation varied between countries. Children with cerebral palsy participated less frequently in many but not all areas of everyday life, compared with children from the general population. There was regional variation in the domains with reduced participation and in the magnitude of the differences. We discuss how this regional variation might be explained by the different environments in which children live. Attending a special school or class was not associated with further reduction in participation in most areas of everyday life.

Antioxidants and periodontitis in 60-70 year- old men

Objective: The aim was to investigate the association between periodontal health and the serum levels of various antioxidants including carotenoids, retinol and vitamin E in a homogenous group of Western European men.
Materials and Methods: A representative sample of 1258 men aged 60-70 years, drawn from the population of Northern Ireland, was examined between 2001 and 2003. Each participant had six or more teeth, completed a questionnaire and underwent a clinical periodontal examination. Serum lipid-soluble antioxidant levels were measured by high-performance liquid chromatography with diode array detection. Multivariable analysis was carried out using logistic regression with adjustment for possible confounders. Models were constructed using two measures of periodontal status (low- and high-threshold periodontitis) as dependent variables and the fifths of each antioxidant as a predictor variable.
Results: The levels of a- and ß-carotene, ß-cryptoxanthin and zeaxanthin were highly significantly lower in the men with low-threshold periodontitis (p<0.001). These carotenoids were also significantly lower in high-threshold periodontitis. There were no significant differences in the levels of lutein, lycopene, a- and ?-tocopherol or retinol in relation to periodontitis. In fully adjusted models, there was an inverse relationship between a number of carotenoids (a- and ß-carotene and ß-cryptoxanthin) and low-threshold periodontitis. ß-Carotene and ß-cryptoxanthin were the only antioxidants that were associated with an increased risk of high-threshold severe periodontitis. The adjusted odds ratio for high-threshold periodontitis in the lowest fifth relative to the highest fifth of ß-cryptoxanthin was 4.02 (p=0.003).
Conclusion: It is concluded that low serum levels of a number of carotenoids, in particular beta-cryptoxanthin and beta-carotene, were associated with an increased prevalence of periodontitis in this homogenous group of 60-70-year-old Western European men.

Structure and Change: Douglass North's Economics

Douglass North is a pivotal figure in the development of the 'new' economic history as well as the 'new' institutional economics. However, the relationship between these two aspects of his thinking remains undeveloped in previous critical assessments of North's work. The relationship is clarified here. The evidence presented indicates that three distinct phases can be distinguished in his writings between the 1950s and the 2000s. The paper relates these changing views to the shifting mainstream within economics and the effects that this shift has in turn had on economic history research. Economic history has adapted to economic research by abandoning some practices associated with the earlier cliometric literature. Furthermore, North is unique to the extent that his recent writings represent something of a convergence with 'old' institutionalism. © 2010 Taylor & Francis.

National Identity and National Unity in Contemporary East Timorese Literature

Beginning with a panoramic analysis of the role played by East Timorese poets in the struggle for liberation from Portuguese and Indonesian colonial rule, this article examines the extent to which an East Timorese national identity and unity repeatedly featured in the poetry of the 1970s and 80s are represented in contemporary Timorese literary production. By reading the work of the novelist Luís Cardoso, and the poets Abé Barreto and Celso Oliveira, the article also assesses whether the independent nation envisioned earlier by those such as Borja da Costa, Fernando Sylvan and Xanana Gusmão, has been realised. In doing so, critical attention is brought to bear on the intimate relationship between the specific material and political circumstances of East Timor and the literature produced in colonial and postcolonial moments in the nation’s history.
