Contextual determinants of alcohol consumption changes and preventive alcohol policies: a 12-country European study in progress.

Beginning with France in the 1950s, alcohol consumption has decreased in Southern European countries with few or no preventive alcohol policy measures being implemented, while alcohol consumption has been increasing in Northern European countries where historically more restrictive alcohol control policies were in place, even though more recently they were loosened. At the same time, Central and Eastern Europe have shown an intermediate behavior. We propose that country-specific changes in alcohol consumption between 1960 and 2008 are explained by a combination of a number of factors: (1) preventive alcohol policies and (2) social, cultural, economic, and demographic determinants. This article describes the methodology of a research study designed to understand the complex interactions that have occurred throughout Europe over the past five decades. These include changes in alcohol consumption, drinking patterns and alcohol-related harm, and the actual determinants of such changes.

Trends of pre-hospital emergency medical services activity over 10 years : a population-based registry analysis

BACKGROUND: The number of requests to pre-hospital emergency medical services (PEMS) has increased in Europe over the last 20 years, but epidemiology of PEMS interventions has little be investigated. The aim of this analysis was to describe time trends of PEMS activity in a region of western Switzerland. METHODS: Use of data routinely and prospectively collected for PEMS intervention in the Canton of Vaud, Switzerland, from 2001 to 2010. This Swiss Canton comprises approximately 10% of the whole Swiss population. RESULTS: We observed a 40% increase in the number of requests to PEMS between 2001 and 2010. The overall rate of requests was 35/1000 inhabitants for ambulance services and 10/1000 for medical interventions (SMUR), with the highest rate among people aged ≥ 80. Most frequent reasons for the intervention were related to medical problems, predominantly unconsciousness, chest pain respiratory distress, or cardiac arrest, whereas severe trauma interventions decreased over time. Overall, 89% were alive after 48 h. The survival rate after 48 h increased regularly for cardiac arrest or myocardial infarction. CONCLUSION: Routine prospective data collection of prehospital emergency interventions and monitoring of activity was feasible over time. The results we found add to the understanding of determinants of PEMS use and need to be considered to plan use of emergency health services in the near future. More comprehensive analysis of the quality of services and patient safety supported by indicators are also required, which might help to develop prehospital emergency services and new processes of care.

Formation continue dans les services publics en Suisse : quelles stratégies des acteurs dans un environnement managérialisé ?

Dans l'environnement actuel fortement évolutif, les questions relatives à la formation continue sont plus que jamais essentielles. Nombre de publications les abordent toutefois uniquement sous un angle prescriptif, sans considérer le comportement réel du personnel en matière de formation continue. La recherche dont il est question dans cet article vise à mettre en évidence les stratégies que les agents publics suisses mettent en oeuvre, au sein d'organisations soumises à une managérialisation croissante, pour atteindre leurs propres objectifs de formation. Sur la base des analyses effectuées, la conclusion esquisse certains enjeux plus fondamentaux relatifs à l'avenir de la formation continue dans les services publics suisses, enjeux à notre sens largement transposables au sein d'autres pays de l'OCDE (Organisation de coopération et de développement économiques).

New roles for community pharmacists in modern health care systems: a challenge for pharmacy education and research.

Our group is interested in person-centered pharmaceutical services aimed at a more responsible use of drugs (effectiveness, safety, efficiency) in collaboration with physicians and other health care professionals in a primary care setting. The following domains of education and research are high priorities for our group: medication therapy management, medication adherence, integrated care, individualization of therapies, care management for the elderly and e-health.

Pneumothorax sur prise de cocaïne

Introduction: Les complications dues à la cocaïne inhalée se¦rencontrent de plus en plus fréquemment dans les services d'urgence¦et dans la pratique des médecins de premier recours. La survenue de¦complications pulmonaires aiguës de type pneumothorax est¦méconnue.¦Vignette clinique: Un patient de 25 ans consulte aux urgences en¦raison d'une gêne pharyngée, une odynodysphagie et une dysphonie¦en progression depuis 12 h. Il avoue une prise de cocaïne sniffée à 5¦reprises dans les 6 heures précédant l'apparition des symptômes. Des¦crépitations sous-cutanées sont mise en évidence à la palpation du¦creux sus-claviculaire droit, remontant jusqu'à la base du cou. La¦radiographie thoracique confirme un emphysème sous-cutané des¦creux sus-claviculaires (fig. 1). Le patient bénéficie d'une¦oxygénothérapie et d'une observation, avec une évolution¦spontanément favorable.¦Discussion: Après une prise de cocaïne par inhalation profonde, des¦manoeuvres de Valsalva intenses répétées contre glotte fermée sont¦pratiquées, afin d'augmenter la quantité de substance absorbée et donc¦ses effets. Ceci engendre un gradient de pression entre les alvéoles et¦l'interstitium pulmonaire, entraînant une augmentation de la pression¦intra-alvéolaire, puis une rupture des alvéoles avec libération d'air à¦travers les tissus péri-bronchiques dans le médiastin et les tissus¦sous cutanés. En cas de rupture dans la cavité pleurale, il en résulte¦un pneumothorax. Un tabagisme actif est souvent associé, laissant¦suspecter un effet favorisant du tabac sur la survenue des lésions¦pulmonaires. Un traitement conservateur associant antalgie et¦oxygénothérapie s'avère en général suffisant. En présence d'une¦augmentation de la taille du pneumothorax ou de signes de mise¦sous tension, la pose d'un drain thoracique est indiquée. L'arrêt de la¦consommation de cocaïne et du tabac doit être encouragé.¦Conclusion: Un emphysème sous-cutané ou un pneumothorax¦spontané chez un jeune patient doivent faire suspecter une éventuelle¦consommation de cocaïne. Les questions concernant la prise de¦cocaïne ou d'autres substances (alcool, amphétamines, etc.), ainsi¦que son mode d'utilisation et sa fréquence, doivent être formulées¦clairement et réitérées à plusieurs reprises. Le risque de pneumothorax¦existe également lors de consommation occasionnelle et peut entraîner¦des complications pulmonaires importantes.

Contrôle de la qualité des soins: aspects épidémiologiques. [Quality control of health care: epidemiological aspects].

Quality control in health care should be performed by health professionals. To do so they must define indicators, set up studies aimed at measuring and analyzing quality of care, and implement quality assurance programs in health care systems. The elements of a quality improvement program of this kind are described, with special emphasis on the contribution of epidemiology in this field.

Inter-informant agreement and prevalence estimates for substance use disorders: direct interview versus family history method.

OBJECTIVES: Family studies typically use multiple sources of information on each individual including direct interviews and family history information. The aims of the present study were to: (1) assess agreement for diagnoses of specific substance use disorders between direct interviews and the family history method; (2) compare prevalence estimates according to the two methods; (3) test strategies to approximate prevalence estimates according to family history reports to those based on direct interviews; (4) determine covariates of inter-informant agreement; and (5) identify covariates that affect the likelihood of reporting disorders by informants. METHODS: Analyses were based on family study data which included 1621 distinct informant (first-degree relatives and spouses) - index subject pairs. RESULTS: Our main findings were: (1) inter-informant agreement was fair to good for all substance disorders, except for alcohol abuse; (2) the family history method underestimated the prevalence of drug but not alcohol use disorders; (3) lowering diagnostic thresholds for drug disorders and combining multiple family histories increased the accuracy of prevalence estimates for these disorders according to the family history method; (4) female sex of index subjects was associated with higher agreement for nearly all disorders; and (5) informants who themselves had a history of the same substance use disorder were more likely to report this disorder in their relatives, which entails the risk of overestimation of the size of familial aggregation. CONCLUSION: Our findings have important implications for the best-estimate procedure applied in family studies.

Longer-term impacts of mentoring, educational services, and incentives to learn: evidence from a randomized trial in the United States

This paper is the first to use a randomized trial in the US to analyze the short- and long-term educational and employment impacts of an afterschool program that offered disadvantaged high-school youth: mentoring, educational services, and financial rewards with the objective to improve high-school graduation and postsecondary schooling enrollment. The short-term hefty beneficial average impacts quickly faded away. Heterogeneity matters. While encouraging results are found for younger youth, and when the program is implemented in relatively small communities of 9th graders; detrimental longlived outcomes are found for males, and when case managers are partially compensated by incentive payments and students receive more regular reminders of incentives.

Frailty and use of health and community services by community-dwelling older men: the Concord Health and Ageing in Men Project.

BACKGROUND: frailty is a concept used to describe older people at high risk of adverse outcomes, including falls, functional decline, hospital or nursing home admission and death. The associations between frailty and use of specific health and community services have not been investigated. METHODS: the cross-sectional relationship between frailty and use of several health and community services in the last 12 months was investigated in 1,674 community-dwelling men aged 70 or older in the Concord Health and Ageing in Men study, a population-based study conducted in Sydney, Australia. Frailty was assessed using a modified version of the Cardiovascular Health Study criteria. RESULTS: overall, 158 (9.4%) subjects were frail, 679 (40.6%) were intermediate (pre-frail) and 837 (50.0%) were robust. Frailty was associated with use of health and community services in the last 12 months, including consulting a doctor, visiting or being visited by a nurse or a physiotherapist, using help with meals or household duties and spending at least one night in a hospital or nursing home. Frail men without disability in activities of daily living were twice more likely to have seen a doctor in the previous 2 weeks than robust men (adjusted odds ratio 2.04, 95% confidence interval 1.21-3.44), independent of age, comorbidity and socio-economic status. CONCLUSION: frailty is strongly associated with use of health and community services in community-dwelling older men. The high level of use of medical services suggests that doctors and nurses could play a key role in implementation of preventive interventions.

Expression of substance P and preprotachykinin mRNA by primary sensory neurons in culture: regulation by factors present in peripheral and central target tissues.

Primary sensory neurons display various neuronal phenotypes which may be influenced by factors present in central or peripheral targets. In the case of DRG cells expressing substance P (SP), the influence of peripheral or central targets was tested on the neuronal expression of this neuropeptide. DRG cells were cultured from chick embryo at E6 or E10 (before or after establishment of functional connections with targets). Preprotachykinin mRNA was visualized in DRG cell cultures by either Northern blot or in situ hybridization using an antisense labeled riboprobe, while the neuropeptide SP was detected by immunostaining with a monoclonal antibody. In DRG cell cultures from E10, only 60% of neurons expressed SP. In contrast, DRG cell cultures performed at E6 showed a significant hybridization signal and SP-like immunoreactivity in virtually all the neurons (98%). The addition of extracts from muscle, skin, brain or spinal cord to DRG cells cultured at E6 reduced by 20% the percentage of neurons which express preprotachykinin mRNA and SP-like immunoreactivity. Our results indicate that factors issued from targets inhibit SP-expression by a subset of primary sensory neurons and act on the transcriptional control of preprotachykinin gene.
