Aim: We aimed to explore the meaning of obesity in elderly persons with knee osteoarthritis (KO) and to determine the factors that encourage or discourage weight loss. Background: Various studies have demonstrated that body mass index is related to KO and that weight loss improves symptoms and functional capacity. However, dietary habits are difficult to modify and most education programs are ineffective. Design: A phenomenological qualitative study was conducted. Intentional sampling was performed in ten older persons with KO who had lost weight and improved their health-related quality of life after participating in a health education program. A thematic content analysis was conducted following the stages proposed by Miles and Huberman. Findings: Participants understood obesity as a risk factor for health problems and stigma. They believed that the cause of obesity was multifactorial and criticized health professionals for labeling them as “obese” and for assigning a moral value to slimness and diet. The factors identified as contributing to the effectiveness of the program were a tolerant attitude among health professionals, group education that encouraged motivation, quantitative dietary recommendations, and a meaningful learning model based on social learning theories. Conclusion: Dietary self-management without prohibitions helped participants to make changes in the quantity and timing of some food intake and to lose weight without sacrificing some foods that were deeply rooted in their culture and preferences. Dietary education programs should focus on health-related quality of life and include scientific knowledge but should also consider affective factors and the problems perceived as priorities by patients.

Background: Celiac disease (CD) has a negative impact on the health-related quality of life (HRQL) of affected patients. Although HRQL and its determinants have been examined in Spanish CD patients specifically recruited in hospital settings, these aspects of CD have not been assessed among the general Spanish population. Methods: An observational, transversal study of a non-randomized, representative sample of adult celiac patients throughout all of Spain's Autonomous Regions. Subjects were recruited through celiac patient associations. A Spanish version of the self-administered Celiac Disease-Quality of Life (CD-QOL) questionnaire was used. Determinant factors of HRQL were assessed with the aid of multivariate analysis to control for confounding factors. Results: We analyzed the responses provided by 1,230 patients, 1,092 (89.2%) of whom were women. The overall mean value for the CD-QOL index was 56.3 ± 18.27 points. The dimension that obtained the most points was dysphoria, with 81.3 ± 19.56 points, followed by limitations with 52.3 ± 23.43 points; health problems, with 51.6 ± 26.08 points, and inadequate treatment, with 36.1 ± 21.18 points. Patient age and sex, along with time to diagnosis, and length of time on a gluten-free diet were all independent determinant factors of certain dimensions of HRQL: women aged 31 to 40 expressed poorer HRQL while time to diagnosis and length of time on a gluten-free diet were determinant factors for better HRQL scores. Conclusions: The HRQL of adult Spanish celiac subjects is moderate, improving with the length of time patients remain on a gluten-free diet.

Because millions of youth are involved in sport, the sport context is important to consider in advancing the growth experiences of young people (Cˆot´e et al., 2007; Fraser-Thomas et al., 2005). Furthermore, research in developmental psychology has highlighted the value of structured programs, including sport, in helping to promote positive youth development (Fredricks & Eccles, 2006). Youth sport involvement has been linked to high levels of enjoyment (Scanlan et al., 1989), however, negative outcomes, such as burnout, have also been reported (Gould et al., 1996). In the present study, the Developmental Assets Profile (Search Institute, 2004) was used to explore personal (internal assets) and contextual (external assets) outcomes associated with youth sport. Results suggest that three particular assets (positive identity, empowerment, and support) are important to focus on in youth sport programs to decrease burnout symptoms and enhance enjoyment. Path analyses were also conducted to test a proposed model and exploratory results confirmed links of particular assets to sport outcomes. The results are discussed in terms of integration with Bronfenbrenner’s ecological theory (1999) and recommendations are suggested for sport programmers to consider to develop these assets within youth sport.

Introduction. One frequently hears the question posed in the title to this report, but there is little systematic analytical literature on the issue. Fragmented evidence or anecdotes dominate debates among EU regulatory decision-makers and in European business, insofar as there is a genuine debate at all. This CEPS Special Report focuses on the multi-faceted, ambiguous and complex relationship between (EU) regulation and innovation in the economy, and discusses the innovation-enhancing potential of certain regulatory approaches as well as factors that tend to reduce incentives to innovate. It adopts an 'ecosystem' approach to both regulation and innovation, and study the interactions between the two ecosystems. This general analysis and survey are complemented by seven case studies of EU regulation enabling and disabling innovation, two horizontal and five sectoral ones. The case studies are preceded by a broader contextual analysis of trends in EU regulation over the last three decades. These trends show the significant transformation of the nature as well as improvement of the quality of EU regulation, largely in the deepened internal market, which tend to have a favourable and lasting effect on the rate of innovation in the EU (other things being equal). Among the findings include the following: Regulation can at times be a powerful stimulus to innovation. EU regulation matters at all stages of the innovation process. Different types of regulation can be identified in terms of innovation impact: general or horizontal, innovation-specific and sector-specific regulation. More prescriptive regulation tends to hamper innovative activity, whereas the more flexible EU regulation is, the better innovation can be stimulated. Lower compliance and red-tape burdens have a positive effect on innovation. The authors recommend incorporating a specific test on innovation impacts in the ex-ante impact assessment of EU legislation as well as in ex-post evaluation. There is ample potential for fostering innovation by reviewing the EU regulatory acquis.

BACKGROUND  While liver-related deaths in HIV and hepatitis C virus (HCV) co-infected individuals have declined over the last decade, hepatocellular carcinoma (HCC) may have increased. We described the epidemiology of HCC and other liver events in a multi-cohort collaboration of HIV/HCV co-infected individuals. METHODS  We studied all HCV antibody-positive adults with HIV in the EuroSIDA Study, the Southern Alberta Clinic Cohort, the Canadian Co-infection Cohort, and the Swiss HIV Cohort Study from 2001 to 2014. We calculated the incidence of HCC and other liver events (defined as liver-related deaths or decompensations, excluding HCC) and used Poisson regression to estimate incidence rate ratios. RESULTS  Our study comprised 7,229 HIV/HCV co-infected individuals (68% male, 90% white). During follow-up, 72 cases of HCC and 375 other liver events occurred, yielding incidence rates of 1.6 (95% confidence interval (CI): 1.3, 2.0) and 8.6 (95% CI: 7.8, 9.5) cases per 1,000 person-years of follow-up, respectively. The rate of HCC increased 11% per calendar year (95% CI: 4%, 19%) and decreased 4% for other liver events (95% CI: 2%, 7%), but only the latter remained statistically significant after adjustment for potential confounders. High age, cirrhosis, and low current CD4 cell count were associated with a higher incidence of both HCC and other liver events. CONCLUSIONS  In HIV/HCV co-infected individuals, the crude incidence of HCC increased from 2001 to 2014, while other liver events declined. Individuals with cirrhosis or low current CD4 cell count are at highest risk of developing HCC or other liver events.

Stanford Research Institute conducted this study to provide information to assist the Atomic Energy Commission in preparing a research and development program leading to the commercial application of radiation pasteurization for selected fruits and vegetables. Under the Quartermaster Corps' extensive program of research on irradiated foods, the five fruits and vegetables (strawberries, peaches, citrus fruits, grapes and tomatoes) of interest to the AEC have been irradiated experimentally. Results are inconclusive, but there are indications of both shelf-life extension and unfavorable radiation effects observed at dose levels below 500,000 rads.
