Psychosocial stress and cardiovascular risk : current opinion

Cardiovascular disease (CVD) is a major cause of morbidity and mortality worldwide. Epidemiologic research of the last half-century has clearly shown that psychosocial factors related to the social environment, personality characteristics, and negative affect increase the risk of incident CVD and also impact prognosis of cardiac patients. Several mechanisms may explain this link, including a genetic predisposition, poor lifestyle choices, low adherence to health recommendations, and direct pathophysiologic perturbations. The latter include alteration of the hypothalamic-pituitary adrenal axis and autonomic dysfunction resulting in endothelial dysfunction, inflammation, and a prothrombotic state further downstream. Screening for psychosocial factors seems appropriate as part of the standard history and based on the clinician's knowledge of the patient and the purpose of the visit. Psychological interventions generally alleviate distress in cardiac patients, but whether they reduce the risk of hard cardiovascular endpoints and all-cause mortality is less evident. Cardiac patients with more severe depression may particularly profit from antidepressant medications. Due to their pharmacologic properties, selective serotonin reuptake inhibitors were shown to improve cardiovascular outcome. The most effective psychosocial treatment is multicomponent therapy that combines elements of cognitive behaviour therapy ("stress management") and changes in health behaviours, including the adoption of a regular exercise regimen. Gender-specific issues should probably be considered. The field of behavioural cardiology has accumulated a wealth of epidemiological, mechanistic and clinical knowledge that undoubtedly has furthered our understanding about the important role of psychosocial risk factors in patients with a heart disease.

Strabismus and employment: the opinion of headhunters

Abstract. Purpose: The aim of this study was to determine the influence of strabismus on an individual's ability to find employment based on the opinion of Swiss headhunters. Methods: Forty Swiss headhunters retrieved from a Swiss online telephone directory were interviewed using a validated questionnaire in order to determine if strabismus would have an impact on a person's ability to find employment. Photographs of a strabismic man and woman as well as of other computer-generated facial anomalies could be downloaded from the Internet during the interview. Results: 72.5% of headhunters judged that strabismic individuals would have more difficulties in finding a job than orthotropic persons. These difficulties were judged to be stronger in women than in men (P = 0.006), and in exotropic compared to esotropic persons (P = 0.01). Asked about seven facial anomalies, exotropia was found to have the third and esotropia the fourth (women) or fifth (men) most strongly negative impact on finding employment, after having strong acne and a visible missing tooth. Headhunters judged that persons with strabismus are significantly perceived as less attractive and less intelligent by potential employers. Conclusion: Visible strabismus negatively influences individuals' ability to find a job and therefore has an impact on their economic status. Successful strabismus surgery realigns the visual axes, producing a normal facial appearance and therefore eliminating the negative impact of strabismus on employability.

Opinion of headhunters about the ability of strabismic subjects to obtain employment

BACKGROUND: Through the opinion of Swiss headhunters, we wanted to determine the influence of strabismus on the ability to obtain employment. METHODS: Out of 31 randomly selected Swiss headhunters, 20 could be interviewed using a validated questionnaire. RESULTS: Forty-seven percent of the headhunters judged that strabismic subjects have more difficulties in obtaining a job. Gender has no influence on discrimination (p > 0.1). Asked about six facial disfigurements, strabismus was found to have the second largest negative impact on employment directly after acne. Strabismus was estimated to decrease the attractiveness of job applicants (p < 0.0001) and to have a negative impact on the overall judgment of a potential employer (p < 0.05). CONCLUSIONS: Visible strabismus influences negatively the ability to obtain a job. Because of its impact on the employability of a person, we believe that strabismus surgery in adults cannot be considered to be only a beautifying procedure.

Political Depolarization in German Public Opinion, 1980–2010

Little is known about political polarization in German public opinion. This article offers an issue-based perspective and explores trends of opinion polarization in Germany. Public opinion polarization is conceptualized and measured as alignment of attitudes. Data from the German General Social Survey (1980 to 2010) comprise attitudes towards manifold issues, which are classified into several dimensions. This study estimates multilevel models that reveal general and issue- as well as dimension-specific levels and trends in attitude alignment for both the whole German population and sub-groups. It finds that public opinion polarization has decreased over the last three decades in Germany. In particular, highly educated and more politically interested people have become less polarized over time. However, polarization seems to have increased in attitudes regarding gender issues. These findings provide interesting contrasts to existing research on the American public.

Expert opinion on toxicity profiling--report from a NORMAN expert group meeting.

This article describes the outcome and follow-up discussions of an expert group meeting (Amsterdam, October 9, 2009) on the applicability of toxicity profiling for diagnostic environmental risk assessment. A toxicity profile was defined as a toxicological "fingerprint" of a sample, ranging from a pure compound to a complex mixture, obtained by testing the sample or its extract for its activity toward a battery of biological endpoints. The expert group concluded that toxicity profiling is an effective first tier tool for screening the integrated hazard of complex environmental mixtures with known and unknown toxicologically active constituents. In addition, toxicity profiles can be used for prioritization of sampling locations, for identification of hot spots, and--in combination with effect-directed analysis (EDA) or toxicity identification and evaluation (TIE) approaches--for establishing cause-effect relationships by identifying emerging pollutants responsible for the observed toxic potency. Small volume in vitro bioassays are especially applicable for these purposes, as they are relatively cheap and fast with costs comparable to chemical analyses, and the results are toxicologically more relevant and more suitable for realistic risk assessment. For regulatory acceptance in the European Union, toxicity profiling terminology should keep as close as possible to the European Water Framework Directive (WFD) terminology, and validation, standardization, statistical analyses, and other quality aspects of toxicity profiling should be further elaborated.

Tocolysis for preterm labor: expert opinion

Tocolysis is an important treatment in the improvement of outcome in preterm labor and preterm birth, provided that its use follows clear evidence-based recommendations. In this expert opinion, the most recent evidence about efficacy and side effects of different tocolytics is being reviewed and evidence-based recommendation about diagnosis and treatment of preterm labor is given. Further aspects such as progesterone administration or antibiotic treatment for the prevention of preterm birth are included. Our review demonstrates that an individualized choice of different tocolytics and additional treatments is necessary to improve short- and long-term neonatal outcome in preterm labor and preterm birth.

CAP Reform vs WTO: Crop Diversification or Crop Rotation? : Legal opinion prepared by Dr. Christian Häberli at the request of APRODEV, the Association of World Council of Churches related Development Organisations in Europe

The European Commission’s proposals for the Legislative Framework of the Common Agricultural Policy (CAP) in the period 2014-2020 include, inter alia, the introduction of a “strong greening component”. For the first time, all EU farmers in receipt of support are to “go beyond the requirements of cross compliance and deliver environmental and climate benefits as part of their everyday activities crop diversification as a contribution to all EU farmers in receipt of support go beyond the requirements of cross compliance and deliver environmental and climate benefits as part of their everyday activities.” In a legal opinion prepared at the request of APRODEV, the Association of World Council of Churches related Development Organisations in Europe (www.aprodev.eu), Christian Häberli examines the WTO implications of this proposal, as compared with an alternative proposal to rather link direct payments to crop rotation. The conclusions are twofold: 1. Crop rotation is at least as likely to be found Green Box-compatible as crop diversification. Moreover, it will be more difficult to argue that crop diversification is “not more than minimally production-distorting” because it entails for most farmers less cost and work. 2. Even if (either of the two cropping schemes) were to be found “amber”, the EU would not have to relinquish this conditionality. This is because the direct payments involved would in all likelihood not, together with the other price support instruments, exceed the amount available under the presently scheduled maximum.

Deliberative and non-deliberative persuasion: Mechanisms of opinion formation in EuroPolis

From a normative vantage point, post-deliberative opinions should be linked to the quality of arguments presented during discussion. Yet, there is a dearth of research testing this claim. Our study makes a first attempt to overcome this deficiency. By analyzing a European deliberative poll on third country migration, we explore whether statements backed by reason affect opinions, which we term deliberative persuasion. We contrast deliberative persuasion to non-deliberative persuasion, whereby we explore whether the most frequently repeated position influences opinions. We find that with regard to regularization of irregular immigrants, deliberative persuasion took place. In the context of European involvement in immigration affairs, however, opinions are driven by the most frequently repeated position rather than by the quality of argumentation.

Expert Opinion on the Perceived Effectiveness and Importance of On-Farm Biosecurity Measures for Cattle and Swine Farms in Switzerland.

Biosecurity is crucial for safeguarding livestock from infectious diseases. Despite the plethora of biosecurity recommendations, published scientific evidence on the effectiveness of individual biosecurity measures is limited. The objective of this study was to assess the perception of Swiss experts about the effectiveness and importance of individual on-farm biosecurity measures for cattle and swine farms (31 and 30 measures, respectively). Using a modified Delphi method, 16 Swiss livestock disease specialists (8 for each species) were interviewed. The experts were asked to rank biosecurity measures that were written on cards, by allocating a score from 0 (lowest) to 5 (highest). Experts ranked biosecurity measures based on their importance related to Swiss legislation, feasibility, as well as the effort required for implementation and the benefit of each biosecurity measure. The experts also ranked biosecurity measures based on their effectiveness in preventing an infectious agent from entering and spreading on a farm, solely based on transmission characteristics of specific pathogens. The pathogens considered by cattle experts were those causing Bluetongue (BT), Bovine Viral Diarrhea (BVD), Foot and Mouth Disease (FMD) and Infectious Bovine Rhinotracheitis (IBR). Swine experts expressed their opinion on the pathogens causing African Swine Fever (ASF), Enzootic Pneumonia (EP), Porcine Reproductive and Respiratory Syndrome (PRRS), as well as FMD. For cattle farms, biosecurity measures that improve disease awareness of farmers were ranked as both most important and most effective. For swine farms, the most important and effective measures identified were those related to animal movements. Among all single measures evaluated, education of farmers was perceived by the experts to be the most important and effective for protecting both Swiss cattle and swine farms from disease. The findings of this study provide an important basis for recommendation to farmers and policy makers.
