Administering brief motivational interventions to young men: Results from a pilot census transmissible study among 19 year-old francophone Swiss men.

AIMS - To pilot the implementation of brief motivational intervention (BMI) among conscripts, and to test the effectiveness of BMI in young men voluntarily showing up for a single face-to-face alcohol BMI session. Participants were conscripts attending the army recruitment process in Lausanne. This process is mandatory for all Swiss males at age 19 and Lausanne serves all francophone Swiss men. METHODS - Of 3'227 young men that were seen during the army recruitment procedures, 445 voluntarily showed up for a BMI and 367 were included in the study (exclusions were random and unsystematic and related to organizational aspects in the recruitment center). After an initial assessment, subjects were randomized into two groups: an immediate BMI and a 6-month delayed BMI (waiting list design). A 6-month follow-up assessment was conducted in both groups. BMI was a face-to-face 20 minutes counseling session with a psychologist trained in motivational interviewing at baseline and a telephone session for the control group at follow-up. Strategies of BMI included the exploration and evocation of a possible behavior change, importance of future change, readiness to change, and commitment to change. A filmed example of such an intervention is available in French at www.alcoologie.ch. RESULTS - All procedures are now fully implemented and working and the provision of preventive efforts found general approval by the army. 3'227 were eligible for BMI and 445 of them (13.8%) showed up for receiving a BMI. 367 were included in the study, 181 in the BMI group and 186 in the control group. More than 86% of those included were reached at follow-up. With one exception all findings on alcohol use went in the expected direction, i.e. a stronger decrease in alcohol use (or a smaller increase as for usual weekly drinking amount) in the BMI group. The risk for risky single occasion drinking (RSOD) decreased from 57% at-risk users at baseline to 50.6%, i.e. a 6.4% point decrease in the BMI group, while there was only a 0.6% point decrease (from 57.5% to 56.9%) in the control group. Moreover, the study showed that there was a likelihood of crossover effects for other substances like tobacco smoking and cannabis use. Despite these encouraging and consistent positive findings, none reached significance at conventional levels (p < 0.05). DISCUSSION - Data suggest a beneficial impact of BMI on alcohol use outcomes and potential effect on other substance use in 19-year old men attending the army recruitment and showing up voluntarily for BMI. As the main aim was to implement and test feasibility of conducting BMI in this setting none of our findings reached statistical significance. The consistency of findings across measures and substances, however, raises hope that non-significance in the present study does not mean no effect, but mainly insufficient power of this pilot study.

Psychosocial care for the caregivers of primary malignant brain tumor patients.

Despite clinical experience that suggests a high burden of care among relatives of individuals with a primary malignant brain tumor (PMBT), little is known about their actual needs. In this study, the caregivers' personal experiences, quality of life, burden of care, and psychological well-being were examined. Fifty-nine percent did not receive any financial aid for home care, 33% had increased risk for psychosomatic problems, 45% had anxiety, and 33% increased depression levels. The caregiver's quality of life was most strongly affected by the burden of care (p < .001) and the patient's mental state (p < .03). To improve the situation, empathetic professionals and an early implementation of palliative care and social work are required.

La prévention du suicide en milieu scolaire est-elle possible [Is it possible to run suicide prevention interventions within the school setting?]

Suicide represent the second cause of death in Switzerland and, between 15 and 20 years of age, 8% of girls and 4% of boys have attempted suicide at least once in their life. "Universal" primary prevention in schools is usually run through courses dealing with the issue of suicide and which are systematically provided to all pupils. There is no evidence that they have any positive effect and even they may be in some instances harmful. The training of professionals working in the school setting to better identify and refer adolescents facing risky situation is probably effective. Another promising approach is the one which aims at improving the school climate in increasing social connectedness and the pupils' life skills. Finally, the school which faces a suicide should set up debriefing activities, thus deterring vulnerable pupils to engage in violent acting as a result of a contamination process.

The effectiveness of brief alcohol interventions in primary care settings: a systematic review.

Issues. Numerous studies have reported that brief interventions delivered in primary care are effective in reducing excessive drinking. However, much of this work has been criticised for being clinically unrepresentative. This review aimed to assess the effectiveness of brief interventions in primary care and determine if outcomes differ between efficacy and effectiveness trials. Approach. A pre-specified search strategy was used to search all relevant electronic databases up to 2006. We also hand-searched the reference lists of key articles and reviews. We included randomised controlled trials (RCT) involving patients in primary care who were not seeking alcohol treatment and who received brief intervention. Two authors independently abstracted data and assessed trial quality. Random effects meta-analyses, subgroup and sensitivity analyses and meta-regression were conducted. Key Findings. The primary meta-analysis included 22 RCT and evaluated outcomes in over 5800 patients. At 1 year follow up, patients receiving brief intervention had a significant reduction in alcohol consumption compared with controls [mean difference: -38 g week(-1), 95%CI (confidence interval): -54 to -23], although there was substantial heterogeneity between trials (I(2) = 57%). Subgroup analysis confirmed the benefit of brief intervention in men but not in women. Extended intervention was associated with a non-significantly increased reduction in alcohol consumption compared with brief intervention. There was no significant difference in effect sizes for efficacy and effectiveness trials. Conclusions. Brief interventions can reduce alcohol consumption in men, with benefit at a year after intervention, but they are unproven in women for whom there is insufficient research data. Longer counselling has little additional effect over brief intervention. The lack of differences in outcomes between efficacy and effectiveness trials suggests that the current literature is relevant to routine primary care.

Personality, psychosocial and health-related predictors of quality of life in old age.

OBJECTIVES: Beyond its well-documented association with depressive symptoms across the lifespan, at an individual level, quality of life may be determined by multiple factors: psychosocial characteristics, current physical health and long-term personality traits. METHOD: Quality of life was assessed in two distinct community-based age groups (89 young adults aged 36.2 ± 6.3 and 92 older adults aged 70.4 ± 5.5 years), each group equally including adults with and without acute depressive symptoms. Regression models were applied to explore the association between quality of life assessed with the World Health Organization Quality of Life - Bref (WHOQOL-Bref) and depression severity, education, social support, physical illness, as well as personality dimensions as defined by the Five-Factor Model. RESULTS: In young age, higher quality of life was uniquely associated with lower severity of depressive symptoms. In contrast, in old age, higher quality of life was related to both lower levels of depressive mood and of physical illness. In this age group, a positive association was also found between quality of life and higher levels of Openness to experience and Agreeableness personality dimensions. CONCLUSION: Our data indicated that, in contrast to young cohorts, where acute depression is the main determinant of poor quality of life, physical illness and personality dimensions represent additional independent predictors of this variable in old age. This observation points to the need for concomitant consideration of physical and psychological determinants of quality of life in old age.

Genetic Structure of Triatoma sordida (Hemiptera: Reduviidae) Domestic Populations from Bolivia: Application on Control Interventions

The genetic population of Triatoma sordida group 1, a secondary vector of Chagas disease in Bolivia, was studied by multi-locus enzyme electrophoresis. A total of 253 nymphal and adult specimens collected from seven neighbouring localities in the Velasco Province, Department of Santa Cruz, were processed. The relatively low genetic variability was confirmed for this species (rate of polymorphism: 0.20). The absence of genetic disequilibrium detected within the seven localities was demonstrated. A geographical structuration appears between localities with distances greater than 20 km apart. Although T. sordida presents a relatively reduced dispersive capacity, its panmictic unit is wider than compared with T. infestans. Genetic distances between T. sordida populations were correlated with geographic distance. Gene flow between geographic populations of T. sordida provides an efficient framework for effective vigilance and control protocols.

Breath acetone to monitor life style interventions in field conditions: An exploratory study.

OBJECTIVE: To assess whether breath acetone concentration can be used to monitor the effects of a prolonged physical activity on whole body lipolysis and hepatic ketogenesis in field conditions. METHODS: Twenty-three non-diabetic, 11 type 1 diabetic, and 17 type 2 diabetic subjects provided breath and blood samples for this study. Samples were collected during the International Four Days Marches, in the Netherlands. For each participant, breath acetone concentration was measured using proton transfer reaction ion trap mass spectrometry, before and after a 30-50 km walk on four consecutive days. Blood non-esterified free fatty acid (NEFA), beta-hydroxybutyrate (BOHB), and glucose concentrations were measured after walking. RESULTS: Breath acetone concentration was significantly higher after than before walking, and was positively correlated with blood NEFA and BOHB concentrations. The effect of walking on breath acetone concentration was repeatedly observed on all four consecutive days. Breath acetone concentrations were higher in type 1 diabetic subjects and lower in type 2 diabetic subjects than in control subjects. CONCLUSIONS: Breath acetone can be used to monitor hepatic ketogenesis during walking under field conditions. It may, therefore, provide real-time information on fat burning, which may be of use for monitoring the lifestyle interventions.

Effectiveness of interventions targeting frequent users of emergency departments: a systematic review

L'article publié de le cadre de cette thèse est intitulé "Effectiveness of interventions targeting frequent users of emergency departments: A systematic review." Il a été publié par les "Annals of Emergency Medicine (AEM)" en juillet 2011. Le titre en français pourrait être: "Efficacité des interventions ciblant les utilisateurs fréquents des services d'urgence: Une revue systématique." Le titre du journal américain pourrait être: "Annales de Médecine d'Urgence". Il s'agit du journal du "Collège Américain des Médecins d'Urgence", en anglais "American College of Emergency Physicians (ACEP)". L'article a été soumis à l'AEM en raison de l'intérêt que ses rédacteurs en chef portent pour le sujet des utilisateurs fréquents des services d'urgence, démontré depuis plus de dix ans par la publication de nombreux articles dans ce domaine. Le facteur d'impact de l'AEM est de surcroît le plus important des journaux d'urgence, assurant ainsi une large diffusion des articles publiés. Lors de sa publication, l'article a été accompagné d'un éditorial signé par le Docteur Maria C. Raven, médecin au Centre Hospitalier de Bellevue à New York, Etats-Unis.¦Contexte et enjeux¦La Direction Générale du Centre Hospitalier Vaudois (CHUV) finance, dans le cadre du plan stratégique 2009-2013, un axe "populations vulnérables". Cet axe est porté en grande partie par des projets développés au sein de la Policinlique Médicale Universitaire et l'Unité des Populations Vulnérables qui prend en charge, enseigne la prise en charge et s'interroge sur la prise en charge des personnes les plus vulnérables. C'est dans ce contexte que nous avons été amenés à réfléchir à l'existence éventuelle de marqueurs de vulnérabilité; l'utilisation fréquente des services d'urgence par certains individus constitue à n'en pas douter l'un de ces marqueurs. Il existe une importante littérature décrivant en détail ces utilisateurs fréquents des services d'urgence, raison pour laquelle nous avons décidé de faire un pas supplémentaire et de nous interroger sur l'efficacité des interventions (quelle qu'elles soient) ciblant cette population particulière. Nous avons ainsi entrepris une revue systématique de la littérature scientifique médicale et sociale pour approfondir cette question, et c'est précisément le résultat de cette recherche qui constitue ce travail de thèse.¦Conclusions et perspectives¦Les utilisateurs fréquents des services d'urgence sont des individus particulièrement vulnérables, et ce aussi bien aux Etats-Unis, qu'en Europe ou en Australie: ils présentent par exemple une mortalité supérieure aux autres utilisateurs des urgences; ils sont également plus à risque de présenter une consommation abusive d'alcool ou de drogues, une maladie mentale, ou une maladie chronique. Ils sont plus souvent sans abri, sans assurance et d'un statut socio-économique bas.¦De nombreuses interventions on été développées pour prendre en charge les utilisateurs fréquents des urgences. Le but de ces interventions est d'une part de réduire la consommation des services d'urgence et d'autre part d'améliorer la santé au sens large de ces patients vulnérables. C'est en ces termes (réduction de la fréquence d'utilisation des services d'urgence et amélioration de la santé) que l'efficacité d'une intervention est mesurée.¦Parmi l'ensemble des interventions étudiées, l'une semble particulièrement efficace pour réduire le nombre de visites aux urgences et améliorer un certain nombre de marqueurs sociaux (accès à un logement ou à une assurance-maladie). Cette intervention est appelée "case management" (ou "gestion de cas", difficile tentative de traduction de ce concept en français), et consiste en une approche multidisciplinaire (médecins, infirmiers, assistants sociaux) fournissant un service individualisé, dans le cadre de l'hôpital et souvent également dans la communauté. L'approche consiste à évaluer les besoins précis du patient, à l'accompagner dans son parcours de soin, à l'orienter si nécessaire et à mettre en place autour de lui un réseau communiquant de manière adaptée.¦Le "case management" ayant montré son efficacité dans la prise en charge des utilisateurs fréquents des services d'urgence, y-compris en termes de coûts, notre conclusion va dans le sens d'encourager les hôpitaux à évaluer l'importance de ce phénomène dans leur propre pratique et à mettre en place des équipes de prise en charge de ces patients, dans le double but de soutenir des patients particulièrement vulnérables et de réduire la consommation des services d'urgence. Suite à la réflexion suscitée par ce travail de thèse, une telle équipe a été mise en place en 2010, dans un cadre de recherche-action, au niveau du CHUV. Ce projet est dirigé par le Dr Patrick Bodenmann, responsable de l'Unité Populations Vulnérables de la Policlinique Médicale Universitaire de Lausanne. Le Dr Bodenmann est également le directeur de cette thèse et le dernier auteur de la revue systématique.

La reconnaissance et le sens du travail : deux dimensions au coeur des processus de préservation de la santé mentale chez les professionnels des interventions d'urgences médicales préhospitalières

Le travail en situations d'urgence, notamment médicale, comporte de nombreux facteurs de risque pour la santé mentale. Cependant, des études récentes suggèrent que la reconnaissance de même que certains aspects relatifs au sens du travail pourraient permettre aux individus de préserver leur équilibre psychique malgré la présence de stresseurs importants.Nous avons effectué une étude portant sur la santé au travail pour des ambulanciers travaillant en Suisse romande. Dans un premier temps, une phase qualitative centrée sur l'observation du travail réel a été effectuée. Les observations ont été effectuées dans 11 services pour un total de 416 heures d'observation. Dans un second temps, un questionnaire a été développé et administré à l'ensemble des ambulanciers de Suisse romande.Notre étude a notamment permis de confirmer l'importance de la reconnaissance et du sens du travail pour les ambulanciers.

Les urgences: une opportunité d'accès a des interventions préventives en partenariat avec les médecins de premier recours [Preventive medicine in emergency centres: an opportunity of partnership for emergency physicians and primary care physicians].

Whereas preventive interventions for primary care physicians are now well established, the preventive interventions in emergency departments have been only partially and recently evaluated. Emergency departments probably represent however an opportunity for preventive medicine. Indeed, the population, sometimes vulnerable, consulting emergency departments, frequently presents risks factors and risks behaviours. Moreover, the concept of &quot;teachable moment&quot; and the studies recently performed seem to confirm this hypothesis. This article review the currently preventive interventions recommended in emergency departments and discuss the rationale to implement preventive medicine in emergency departments and the limits of this process.
