Dépistage du cancer du sein par l'examen physique: qui en bénéficie? [Physical examination in screening for breast cancer: who benefits?].

A survey was undertaken among a representative sample of the female population, aged 20 to 74, of the Canton of Vaud, Switzerland (total population 550,000) to assess the knowledge, attitudes and practices of women in respect to breast cancer and its prevention. The present study focuses on access by women to medical preventive measures (breast examination by physician and information on breast self-examination). The data are analyzed in relation to the individual risk factors affecting women, in particular age. While with age the risk of breast cancer grows in a linear fashion, the proportion of women having their breast examined by a physician declines. Women over 50 who had no children before the age of 30 constitute an especially high risk category, with the lowest access to information and prevention. This is explained in large part by the fact that they consult gynecologists less often. In this regard it should be noted that a visit to a gynecologist's office is associated much more often with breast examination than a visit to a family physician. It is important to take such findings into account in providing more appropriate and complete care for those groups. This involves sensitization of the physician and improved information for the women themselves.

Mise en place d'un réseau alcoologique coordonné d'indication et de suivi en Suisse romande.

La dépendance à l'alcool est une maladie chronique fréquente aux conséquences multiples qui nécessite un suivi à long terme. Le Service de la santé publique du canton de Vaud a décidé de mettre en place, sur l'ensemble du canton, un dispositif d'indication et de suivi alcoologique coordonné. Les buts d'un tel dispositif, exposé dans le présent article, sont de standardiser l'évaluation, la prise en charge et le suivi des patients alcoolo-dépendants, d'augmenter l'accessibilité aux soins en favorisant des approches thérapeutiques moins lourdes, et d'assurer une meilleure transition entre les structures résidentielles et le réseau ambulatoire. Ce dispositif vise à offrir une meilleure accessibilité aux soins spécialisés, à améliorer la rétention au traitement et une réduction des rechutes.

Health effects of occupational exposure to traffic particles and noise

Exposure to fine particles and noise has been linked to cardiovascular diseases and elevated cardiovascular mortality affecting the worldwide population. Residence and/or work in proximity to emission sources as for example road traffic leads to an elevated exposure and a higher risk for adverse health effects. Highway maintenance workers spend most of their work time in traffic and are exposed regularly to particles and noise. The aims of this thesis were to provide a better understanding of the workers' mixed exposure to particles and noise and to assess cardiopulmonary short term health effects in relation to this exposure. Exposure and health data were collected in collaboration with 8 maintenance centers of the Swiss Road Maintenance Services located in the cantons Bern, Fribourg and Vaud in western Switzerland. Repeated measurements with 18 subjects were conducted during 50 non-consecutive work shifts between Mai 2010 and February 2012, equally distributed over all seasons. In the first part of this thesis we tested and validated measurements of ultrafine particles with a miniature diffusion size classifier (miniDiSC) - a novel particle counting device that was used for the exposure assessment during highway maintenance work. We found that particle numbers and average particle size measured by the miniDiSC were highly correlated with data from the P-TRAK, a condensation particle counter (CPC), as well as from a scanning mobility particle sizer (SMPS). However, the miniDiSC measured significantly more particles than the P-TRAK and significantly less than the SMPS in its full size range. Our data suggests that the instrument specific cutoffs were the main reason for the different particle counts. The first main objective of this thesis was to investigate the exposure of highway maintenance workers to air pollutants and noise, in relation to the different maintenance activities. We have seen that the workers are regularly exposed to high particle and noise levels. This was a consequence of close proximity to highway traffic and the use of motorized working equipment such as brush cutters, chain saws, generators and pneumatic hammers during which the highest exposure levels occurred. Although exposure to air pollutants were not critical if compared to occupational exposure limits, the elevated exposure to particles and noise may lead to a higher risk for cardiovascular diseases in this worker population. The second main objective was to investigate cardiopulmonary short-term health effects in relation to the particle and noise exposure during highway maintenance work. We observed a PM2.5 related increase of the acute-phase inflammation markers C-reactive protein and serum amyloid A and a decrease of TNFa. Heart rate variability increased as a consequence of particle as well as noise exposure. Increased high frequency power indicated a stronger parasympathetic influence on the heart. Elevated noise levels during recreational time, after work, were related to increased blood pressure. Our data confirmed that highway maintenance workers are exposed to elevated levels of particles and noise as compared to the average population. This exposure poses a cardiovascular health risk and it is therefore important to make efforts to better protect the workers health. The use of cleaner machines during maintenance work would be a major step to improve the workers' situation. Furthermore, regulatory policies with the aim of reducing combustion and non-combustion emissions from road traffic are important for the protection of workers in traffic environments and the entire population.

Addictions: le rôle de la psychiatrie

En 2001, l'Organisation mondiale de la santé a publié son rapport sur la santé dans le monde sur le thème de la « santé mentale, nouvelle conception, nouveaux espoirs ». Le rapport partait du constat de l'importance des troubles psychiques en termes de santé publique, de la négligence dont ils sont victimes en général dans le monde, produisant stigmatisation et discrimination. L'OMS a énoncé dix directives pour inspirer les politiques publiques mettant l'accent sur l'action communautaire, l'accessibilité aux soins et la nécessaire interdisciplinarité à l'échelle de la société tout entière. Ces directives ont été entendues tant au niveau européen qu'au niveau suisse, et ont abouti à différents plans de santé mentale, comme récemment dans le canton de Vaud. Les institutions psychiatriques ont dû trouver leur rôle dans ces dispositifs et définir leurs relations avec les partenaires non spécialisés, dans une réflexion sur les filières de soins impliquant chacun, depuis la population générale jusqu'aux acteurs les plus académiques, en passant par tous les étages des dispositifs « santé-social ».

Development and validation of the Transition to Retirement Questionnaire

The aim of this study was to present the initial validation of a new questionnaire, the Transition to Retirement Questionnaire (TRQ) and to study its relationship with resistance to change and personality dimensions. Based on Schlossberg's typology of the retired, the TRQ is designed to assess five dimensions related to personal perceptions of transition to retirement, retirement, and personal plans and activities. The sample consisted of 1,054 professionally active or retired adults from the Swiss French-speaking Canton of Vaud. Exploratory principal components and confirmatory factor analyses highlighted a five-factor solution that fit coherently with Schlossberg's typology. Moreover, TRQ dimensions were related to resistance to change tendencies and personality dimensions. The TRQ seems to be an interesting tool for use in research but also for interventions with young retirees or people preparing for retirement.

Palliative care and prehospital emergency medicine: analysis of a case series.

Palliative care, which is intended to keep patients at home as long as possible, is increasingly proposed for patients who live at home, with their family, or in retirement homes. Although their condition is expected to have a lethal evolution, the patients-or more often their families or entourages-are sometimes confronted with sudden situations of respiratory distress, convulsions, hemorrhage, coma, anxiety, or pain. Prehospital emergency services are therefore often confronted with palliative care situations, situations in which medical teams are not skilled and therefore frequently feel awkward.We conducted a retrospective study about cases of palliative care situations that were managed by prehospital emergency physicians (EPs) over a period of 8 months in 2012, in the urban region of Lausanne in the State of Vaud, Switzerland.The prehospital EPs managed 1586 prehospital emergencies during the study period. We report 4 situations of respiratory distress or neurological disorders in advanced cancer patients, highlighting end-of-life and palliative care situations that may be encountered by prehospital emergency services.The similarity of the cases, the reasons leading to the involvement of prehospital EPs, and the ethical dilemma illustrated by these situations are discussed. These situations highlight the need for more formal education in palliative care for EPs and prehospital emergency teams, and the need to fully communicate the planning and implementation of palliative care with patients and patients' family members.

Identification of potential rockfall source areas at a regional scale using a DEM-based geomorphometric analysis

The availability of high resolution Digital Elevation Models (DEM) at a regional scale enables the analysis of topography with high levels of detail. Hence, a DEM-based geomorphometric approach becomes more accurate for detecting potential rockfall sources. Potential rockfall source areas are identified according to the slope angle distribution deduced from high resolution DEM crossed with other information extracted from geological and topographic maps in GIS format. The slope angle distribution can be decomposed in several Gaussian distributions that can be considered as characteristic of morphological units: rock cliffs, steep slopes, footslopes and plains. A terrain is considered as potential rockfall sources when their slope angles lie over an angle threshold, which is defined where the Gaussian distribution of the morphological unit "Rock cliffs" become dominant over the one of "Steep slopes". In addition to this analysis, the cliff outcrops indicated by the topographic maps were added. They contain however "flat areas", so that only the slope angles values above the mode of the Gaussian distribution of the morphological unit "Steep slopes" were considered. An application of this method is presented over the entire Canton of Vaud (3200 km2), Switzerland. The results were compared with rockfall sources observed on the field and orthophotos analysis in order to validate the method. Finally, the influence of the cell size of the DEM is inspected by applying the methodology over six different DEM resolutions.

Programme vaudois de dépistage du cancer du sein : évaluation après 15 ans, 1999-2013

Le Programme vaudois de dépistage du cancer du sein promeut, organise et mène depuis 1999 une action de prévention auprès de la population féminine du canton âgée de 50 à 69 ans. Premier programme organisé de dépistage du cancer en Suisse, et généralisation d'un projet pilote (1993-1998), le Programme vaudois a grandement contribué au développement d'initiatives similaires dans d'autres cantons. Il demeure aujourd'hui, notamment par son bassin populationnel, le programme suisse qui génère le plus important volume annuel de mammographies de dépistage. Des évaluations indépendantes et régulières permettent de s'assurer que la qualité et l'efficacité d'un programme de dépistage répondent à des normes internationalement admises et périodiquement révisées. Le présent rapport évalue, après 15 ans d'activité (1999-2013), l'évolution temporelle de l'activité de dépistage (chapitre 2), de l'utilisation (chapitre 3) et des performances du programme vaudois de dépistage du cancer du sein (chapitre 4). Couvrant 240'000 mammographies et près de 80'000 femmes, ce rapport s'intéresse aussi, au-delà des indicateurs classiques de performance, à mieux évaluer certains effets indésirables du dépistage comme les résultats faussement positifs ou les cancers survenant entre 2 examens de dépistage (dits cancers d'intervalle), auxquels une section entière est dédiée (chapitre 5). Enfin, la compilation (en annexe) des publications récentes ou les plus significatives liées au programme vaudois et à ses résultats souligne sa visibilité et son implication dans le contexte international, ainsi que son rôle phare en Suisse dans la recherche « evidence-based » sur le dépistage du cancer du sein.
