The Combination of Interferon-Beta and HMG-CoA Reductase Inhibition in Multiple Sclerosis: Enthusiasm Lost too Soon?

Recent studies support the notion that statins, widely prescribed cholesterol-lowering agents, may target key elements in the immunological cascade leading to inflammation and tissue damage in the pathogenesis of multiple sclerosis (MS). Compelling experimental and observational clinical studies highlighted the possibility that statins may also exert immunomodulatory synergy with approved MS drugs, resulting in several randomized clinical trials testing statins in combination with interferon-beta (IFN-?). Some data, however, suggest that this particular combination may not be clinically beneficial, and might actually have a negative effect on the disease course in some patients with MS. In this regard, a small North American trial indicated that atorvastatin administered in combination with IFN-? may increase disease activity in relapsing-remitting MS. Although other trials did not confirm this finding, the enthusiasm for studies with statins dwindled. This review aims to provide a comprehensive overview of the completed clinical trials and reports of the interim analyses evaluating the combination of IFN-? and statins in MS. Moreover, we try to address the evident question whether usage of this combination routinely requires caution, since the number of IFN-?-treated MS patients receiving statins for lowering of cholesterol is expected to grow.

The influence of ego depletion on sprint start performance in athletes without track and field experience

We tested the assumption that ego depletion would affect the sprint start in a sample of N = 38 athletes without track and field experience in an experiment by applying a mixed between- (depletion vs. non-depletion) within- (T1: before manipulation of ego depletion vs. T2: after manipulation of ego depletion) subjects design. We assumed that ego depletion would increase the possibility for a false start, as regulating the impulse to initiate the sprinting movement too soon before the starting signal requires self-control. In line with our assumption, we found a significant interaction as there was only a significant increase in the number of false starts from T1 to T2 for the depletion group while this was not the case for the non-depletion group. We conclude that ego depletion has a detrimental influence on the sprint start in athletes without track and field experience.

Dental knowledge and attitude toward school dental-health programs among parents of kindergarten children in Winterthur.

The current study investigated the attitudes and knowledge regarding diet and oral hygiene of parents with kindergarten children. The parents' statements were evaluated in terms of their socioeconomic background and were compared with the annual clinical examination of the children. The objective of the study was to assess the effectiveness of the school dental-health program and adapt it to today's societal needs. Of those who participated in the interview, 61% were Swiss, 16% were from former Yugoslavia or Turkey, and 12% each from the EU or other countries. Of the children examined, 39% already had caries, and 18% of those showed more than two lesions. The parents' knowledge correlated with the severity of the child's caries as well as with the parents' income, country of origin, and education. There was a correlation between the child's dental decay and lower income, as well as lower education and non-Swiss nationality of the parents. Parents with higher income and better education more often participated in the preschool's preventive program. Parents from former Yugoslavia or Turkey participated less frequently than parents from other countries. The study demonstrated that parents who especially needed instruction and prophylaxis are contacted too late or not at all through the dental-health program at kindergarten and that new approaches to prevention should be implemented to more effectively reach the parents.

[Parent satisfaction with a child and family-centered treatment program for primary headache in childhood and adolescence]

Patient satisfaction represents a significant outcome criterion in the context of systemic psychotherapeutic therapy research. This study investigated parent satisfaction with a psychosocial treatment program (comprising three components: child group therapy, parents' evenings, systemic family sessions) for pediatric primary headache (diagnosed according to IHS criteria). 10 weeks after the end of the treatment program, the parents were sent a questionnaire containing open questions and ten-point numerical rating scales. The sample comprised n=48 families. The return rate was 89%. The qualitative content analysis showed a hierarchical category system consisting of 3 major categories, 7 main groups and 69 sub-categories. The parents stated that they were satisfied with (1.) the effects of the treatment program, (2.) the specific treatment techniques and the medical and psychosocial headache-related information provided, and (3.) the therapeutic relationship. The mean satisfaction for all three therapy components on the ten-point numerical rating scale was 8.1 with a standard deviation of 2.0 (child headache group: 8.5; parents' evenings: 8.2; family sessions: 7.5). The results are discussed with reference to methodological aspects: avoidance of ceiling effects and social desirability in measuring customer satisfaction, order effects of items, weighting of the significance of satisfaction levels as an outcome criterion.

One-year evaluation of a neonatal screening program for cystic fibrosis in Switzerland

BACKGROUND From January 2011 onward, the Swiss newborn screening (NBS) program has included a test for cystic fibrosis (CF). In this study, we evaluate the first year of implementation of the CF-NBS program. METHODS The CF-NBS program consists of testing in two steps: a heel prick sample is drawn (= Guthrie test) for measurement of immunoreactive trypsinogen (IRT) and for DNA screening. All children with a positive screening test are referred to a CF center for further diagnostic testing (sweat test and genetic analysis). After assessment in the CF center, the parents are given a questionnaire. All the results of the screening process and the parent questionnaires were centrally collected and evaluated. RESULTS In 2011, 83 198 neonates were screened, 84 of whom (0.1%) had a positive screening result and were referred to a CF center. 30 of these 84 infants were finally diagnosed with CF (positive predictive value: 35.7%). There was an additional infant with CF and meconium ileus whose IRT value was normal. The 31 diagnosed children with CF correspond to an incidence of 1 : 2683. The average time from birth to genetically confirmed diagnosis was 34 days (range: 13-135). 91% of the parents were satisfied that their child had undergone screening. All infants receiving a diagnosis of CF went on to receive further professional care in a CF center. CONCLUSION The suggested procedure for CF-NBS has been found effective in practice; there were no major problems with its implementation. It reached high acceptance among physicians and parents.
