Le soutien aux autorités lors des votations fédérales de 1971 à 1999 dans les cantons suisses

Cet article vise à expliquer les variations inter-cantonales du succès des autorités ainsi que du soutien populaire qui leur est accordé en votation fédérale entre 1971 et 1999. A cette fin, l'auteur cherche à intégrer deux courants de recherches dans un cadre d'analyse unique en déterminant l'impact respectif des mots d'ordre des partis politiques et des facteurs socio-structurels sur le résultat de vote ainsi que leur effet conjugué. L'analyse empirique, qui est situé au niveau cantonal, est réalisée à l'aide d'une régression logistique et d'un modèle d'équations structurelles. Les résultats obtenus montrent que le caractère alémanique, catholique et agraire d'un canton se traduit par une réticence face à la politique des autorités, qui peut s'amplifier selon le type juridique de la votation et l'enjeu politique soumis au vote. Plus qu'ailleurs, les partis politiques de ces cantons s'alignent cependant fermement derrière la recommandation de vote des autorités et exercent, de ce fait, un effet atténuateur qui contribue au nivellement des disparités inter-cantonales. Ces résultats suggèrent ainsi que les partis politiques cantonaux réussissent, dans une certaine mesure, à contrôler le résultat de vote par le biais d'une concertation accrue durant la phase référendaire.

Gender inequality in health among elderly people in a combined framework of socioeconomic position, family characteristics and social support

This study analyses gender inequalities in health among elderly people in Catalonia (Spain) by adopting a conceptual framework that globally considers three dimensions of health determinants : socio-economic position, family characteristics and social support. Data came from the 2006 Catalonian Health Survey. For the purposes of this study a sub-sample of people aged 65–85 years with no paid job was selected (1,113 men and 1,484 women). The health outcomes analysed were self-perceived health status, poor mental health status and long-standing limiting illness. Multiple logistic regression models separated by sex were fitted and a hierarchical model was fitted in three steps. Health status among elderly women was poorer than among the men for the three outcomes analysed. Whereas living with disabled people was positively related to the three health outcomes and confidant social support was negatively associated with all of them in both sexes, there were gender differences in other social determinants of health. Our results emphasise the importance of using an integrated approach for the analysis of health inequalities among elderly people, simultaneously considering socio-economic position, family characteristics and social support, as well as different health indicators, in order fully to understand the social determinants of the health status of older men and women.

Body fluid and tissue analysis using filter paper sampling support prior to LC-MS/MS: application to fatal overdose with colchicine

Because of the various matrices available for forensic investigations, the development of versatile analytical approaches allowing the simultaneous determination of drugs is challenging. The aim of this work was to assess a liquid chromatography-tandem mass spectrometry (LC-MS/MS) platform allowing the rapid quantification of colchicine in body fluids and tissues collected in the context of a fatal overdose. For this purpose, filter paper was used as a sampling support and was associated with an automated 96-well plate extraction performed by the LC autosampler itself. The developed method features a 7-min total run time including automated filter paper extraction (2 min) and chromatographic separation (5 min). The sample preparation was reduced to a minimum regardless of the matrix analyzed. This platform was fully validated for dried blood spots (DBS) in the toxic concentration range of colchicine. The DBS calibration curve was applied successfully to quantification in all other matrices (body fluids and tissues) except for bile, where an excessive matrix effect was found. The distribution of colchicine for a fatal overdose case was reported as follows: peripheral blood, 29 ng/ml; urine, 94 ng/ml; vitreous humour and cerebrospinal fluid, < 5 ng/ml; pericardial fluid, 14 ng/ml; brain, < 5 pg/mg; heart, 121 pg/mg; kidney, 245 pg/mg; and liver, 143 pg/mg. Although filter paper is usually employed for DBS, we report here the extension of this alternative sampling support to the analysis of other body fluids and tissues. The developed platform represents a rapid and versatile approach for drug determination in multiple forensic media.
