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 "teachable moment" 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.

Infections nosocomiales : interventions et qualité des soins [Maladies infectieuses = Nosocomial infections : quality improvement interventions]

Le développement de méthodes de mesure de la qualité des soins et les actions visant à son amélioration font partie intégrante de la pratique quotidienne. Les infections nosocomiales représentent un Indicateur Incontournable et leur prévention apparaît comme un champ d'action privilégié du concept de l'amélioration continue de la qualité des soins. Dans ce domaine, de nombreuses mesures ont fait l'objet d'études répondant à des critères méthodologiques de qualité élevée, dont les résultats sont hautement significatifs au plan statistique. Les interventions complexes concernant par exemple l'ensemble des patients d'un service ou d'une institution ne permettent que difficilement de satisfaire à ces exigences méthodologiques. Sous certaines conditions, elle peuvent cependant avoir un impact réel et parfois durable sur la qualité des soins. A titre d'exemple, nous discutons deux interventions complexes dans le domaine de la prévention des infections nosocomiales, résultant de démarches visant à une amélioration globale et durable de la qualité des soins. L'utilisation d'outils épidémiologiques adaptés permet également d'estimer le bénéfice des Interventions en milieu hospitalier conformément à ce que la communauté scientifique reconnaît comme étant une recherche clinique de qualité.

Effect of a Road Safety Training Program on Drivers' Comparative Optimism

Reducing comparative optimism regarding risk perceptions in traffic accidents has been proven to be particularly difficult (Delhomme, 2000). This is unfortunate because comparative optimism is assumed to impede preventive action. The present study tested whether a road safety training course could reduce drivers' comparative optimism in high control situations. Results show that the training course efficiently reduced comparative optimism in high control, but not in low control situations. Mechanisms underlying this finding and implications for the design of road safety training courses are discussed.

Laparoscope use and surgical site infections in digestive surgery.

OBJECTIVE: To compare surgical site infection (SSI) rates in open or laparoscopic appendectomy, cholecystectomy, and colon surgery. To investigate the effect of laparoscopy on SSI in these interventions. BACKGROUND: Lower rates of SSI have been reported among various advantages associated with laparoscopy when compared with open surgery, particularly in cholecystectomy. However, biases such as the lack of postdischarge follow-up and confounding factors might have contributed to the observed differences between the 2 techniques. METHODS: This observational study was based on prospectively collected data from an SSI surveillance program in 8 Swiss hospitals between March 1998 and December 2004, including a standardized postdischarge follow-up. SSI rates were compared between laparoscopic and open interventions. Factors associated with SSI were identified by using logistic regression models to adjust for potential confounding factors. RESULTS: SSI rates in laparoscopic and open interventions were respectively 59/1051 (5.6%) versus 117/1417 (8.3%) in appendectomy (P = 0.01), 46/2606 (1.7%) versus 35/444 (7.9%) in cholecystectomy (P < 0.0001), and 35/311 (11.3%) versus 400/1781 (22.5%) in colon surgery (P < 0.0001). After adjustment, laparoscopic interventions were associated with a decreased risk for SSI: OR = 0.61 (95% CI 0.43-0.87) in appendectomy, 0.27 (0.16-0.43) in cholecystectomy, and 0.43 (0.29-0.63) in colon surgery. The observed effect of laparoscopic techniques was due to a reduction in the rates of incisional infections, rather than in those of organ/space infections. CONCLUSION: When feasible, a laparoscopic approach should be preferred over open surgery to lower the risks of SSI.

Psycho-oncological interventions and psychotherapy in the oncology setting.

A person who faces the diagnosis of cancer is subjected to changes within his body, but also with regard to his view of himself and his social relationships. Cancer-related psychological distress occurs frequently and has been reported to have different prevalence according to cancer type and stage of disease. Psychological disorders are known to be underdiagnosed and thus undertreated in the oncology setting, since clinicians might miss the symptoms of psychological distress, misinterpret them, or lack the time and resources to respond adequately. The main psychiatric disturbances observed in patients with cancer are adjustment disorders and affective disorders (anxiety and depression), which in the majority of patients are due to stressors related to the disease and pre-existing psychological vulnerabilities; however, they might also be a direct consequence of biological causes either resulting from treatment side effects or from modifications induced by the cancer. This chapter aims to provide theoretical and practical information concerning psycho-oncological approaches, complemented by some reflexions on their clinical and scientific evidence, focussing essentially on verbal psychological interventions and especially on psychotherapy in patients with cancer.

The UniProtKB/Swiss-Prot Tox-Prot program: A central hub of integrated venom protein data.

Animal toxins are of interest to a wide range of scientists, due to their numerous applications in pharmacology, neurology, hematology, medicine, and drug research. This, and to a lesser extent the development of new performing tools in transcriptomics and proteomics, has led to an increase in toxin discovery. In this context, providing publicly available data on animal toxins has become essential. The UniProtKB/Swiss-Prot Tox-Prot program (http://www.uniprot.org/program/Toxins) plays a crucial role by providing such an access to venom protein sequences and functions from all venomous species. This program has up to now curated more than 5000 venom proteins to the high-quality standards of UniProtKB/Swiss-Prot (release 2012_02). Proteins targeted by these toxins are also available in the knowledgebase. This paper describes in details the type of information provided by UniProtKB/Swiss-Prot for toxins, as well as the structured format of the knowledgebase.

Dietary and lifestyle interventions in the management of the metabolic syndrome: present status and future perspective.

OBJECTIVE: To review the mechanisms underlying the metabolic syndrome, or syndrome X, in humans, and to delineate dietary and environmental strategies for its prevention. DESIGN: Review of selected papers of the literature. RESULTS: Hyperinsulinemia and insulin resistance play a key role in the development of the metabolic syndrome. Strategies aimed at reducing insulin resistance may be effective in improving the metabolic syndrome. They include low saturated fat intake, consumption of low-glycemic-index foods, physical exercise and prevention of obesity. CONCLUSIONS: Future research, in particular the genetic basis of the metabolic syndrome and the interorgan interactions responsible for insulin resistance, is needed to improve therapeutic strategies for the metabolic syndrome.

High expectation in non-evidence-based smoking cessation interventions among smokers--the CoLaus study.

To assess the preferred methods to quit smoking among current smokers. Cross-sectional, population-based study conducted in Lausanne between 2003 and 2006 including 988 current smokers. Preference was assessed by questionnaire. Evidence-based (EB) methods were nicotine replacement, bupropion, physician or group consultations; non-EB-based methods were acupuncture, hypnosis and autogenic training. EB methods were frequently (physician consultation: 48%, 95% confidence interval (45-51); nicotine replacement therapy: 35% (32-38)) or rarely (bupropion and group consultations: 13% (11-15)) preferred by the participants. Non-EB methods were preferred by a third (acupuncture: 33% (30-36)), a quarter (hypnosis: 26% (23-29)) or a seventh (autogenic training: 13% (11-15)) of responders. On multivariate analysis, women preferred both EB and non-EB methods more frequently than men (odds ratio and 95% confidence interval: 1.46 (1.10-1.93) and 2.26 (1.72-2.96) for any EB and non-EB method, respectively). Preference for non-EB methods was higher among highly educated participants, while no such relationship was found for EB methods. Many smokers are unaware of the full variety of methods to quit smoking. Better information regarding these methods is necessary.

Do brief alcohol motivational interventions work like we think they do?

BACKGROUND: Questions remain about how brief motivational interventions (BMIs) for unhealthy alcohol use work, and addressing these questions may be important for improving their efficacy. Therefore, we assessed the effects of various characteristics of BMIs on drinking outcomes across 3 randomized controlled trials (RCTs). METHODS: Audio recordings of 314 BMIs were coded. We used the global rating scales of the Motivational Interviewing Skills Code (MISC) 2.1: counselor's acceptance, empathy, and motivational interviewing (MI) spirit, and patient's self-exploration were rated. MI proficiency was defined as counselor's rating scale scores ≥5. We also used the structure, confrontation, and advice subscale scores of the Therapy Process Rating Scale and the Working Alliance Inventory. We examined these process characteristics in interventions across 1 U.S. RCT of middle-aged medical inpatients with unhealthy alcohol use (n = 124) and 2 Swiss RCTs of young men with binge drinking in a nonclinical setting: Swiss-one (n = 62) and Swiss-two (n = 128). We assessed the associations between these characteristics and drinks/d reported by participants 3 to 6 months after study entry. RESULTS: In all 3 RCTs, mean MISC counselor's rating scales scores were consistent with MI proficiency. In overdispersed Poisson regression models, most BMI characteristics were not significantly associated with drinks/d in follow-up. In the U.S. RCT, confrontation and self-exploration were associated with more drinking. Giving advice was significantly associated with less drinking in the Swiss-one RCT. Contrary to expectations, MI spirit was not consistently associated with drinking across studies. CONCLUSIONS: Across different populations and settings, intervention characteristics viewed as central to efficacious BMIs were neither robust nor consistent predictors of drinking outcome. Although there may be alternative reasons why the level of MI processes was not predictive of outcomes in these studies (limited variability in scores), efforts to understand what makes BMIs efficacious may require attention to factors beyond intervention process characteristics typically examined.

A randomized controlled trial of the effectiveness of a Computer-Assisted Cognitive Remediation (CACR) program in adolescents with psychosis or at high risk of psychosis: Short term and long term outcomes

The present study investigates the short- and long-term outcomes of a computer-assisted cognitive remediation (CACR) program in adolescents with psychosis or at high risk. 32 adolescents participated in a blinded 8-week randomized controlled trial of CACR treatment compared to computer games (CG). Clinical and neuropsychological evaluations were undertaken at baseline, at the end of the program and at 6-month. At the end of the program (n = 28), results indicated that visuospatial abilities (Repeatable Battery for the Assessment of Neuropsychological Status, RBANS; P = .005) improved signifi cantly more in the CACR group compared to the CG group. Furthermore, other cognitive functions (RBANS), psychotic symptoms (Positive and Negative Symptom Scale) and psychosocial functioning (Social and Occupational Functioning Assessment Scale) improved signifi cantly, but at similar rates, in the two groups. At long term (n = 22), cognitive abilities did not demonstrated any amelioration in the control group while, in the CACR group, signifi cant long-term improvements in inhibition (Stroop; P = .040) and reasoning (Block Design Test; P = .005) were observed. In addition, symptom severity (Clinical Global Improvement) decreased signifi cantly in the control group (P = .046) and marginally in the CACR group (P = .088). To sum up, CACR can be successfully administered in this population. CACR proved to be effective over and above CG for the most intensively trained cognitive ability. Finally, on the long-term, enhanced reasoning and inhibition abilities, which are necessary to execute higher-order goals or to adapt behavior to the ever-changing environment, were observed in adolescents benefi ting from a CACR.
