A multicenter, cross-sectional study on the prevalence and risk factors for nasal colonization with Staphylococcus aureus in patients admitted to children's hospitals in Switzerland.

The rate of nasal carriage of Staphylococcus aureus and associated risk factors were determined in a cross-sectional study involving Swiss children's hospitals. S. aureus was isolated in 562 of 1363 cases. In a stepwise multivariate analysis, the variables age, duration of antibiotic use, and hospitalization of a household member were independently associated with carriage of S. aureus.

Antibiotiques et bactéries antibiorésistantes dans les effluents d'hôpitaux : état des lieux en Europe (revue de la littérature)

L'utilisation massive d'antibiotiques dans les établissements de santé participe à la sélection des souches bactériennes résistantes aux antibiotiques. Ces bactéries ainsi que les résidus d'antibiotiques se retrouvent dans les effluents des hôpitaux et atteignent les stations d'épuration communales, où elles ne sont pas systématiquement éliminées par le processus de traitement des eaux. La dissémination d'antibiotiques et de souches résistantes dans l'environnement naturel peut avoir des conséquences non négligeables en termes de santé publique et de perturbations écologiques. En Europe, il semble qu'actuellement très peu d'hôpitaux traitent leurs effluents, mais ceci devrait se généraliser à l'avenir. Le but de cette revue est de faire un état des lieux et une synthèse des études ayant mesuré la présence d'antibiotiques et de bactéries résistantes aux antibiotiques dans les eaux de sorties des hôpitaux et d'évaluer les risques potentiels liés à la dissémination aéroportée (bioaérosols) de ces bactéries dans l'environnement direct de l'hôpital.

Outcome of patients with acute coronary syndrome in hospitals of different sizes in Switzerland

Objective: To assess the impact of patient admission in different hospital types in Switzerland on early in-hospital and 1-year outcomes in patients with acute coronary syndrome (ACS).Methods: From 1997 to 2009, 31,010 ACS patients from 76 Swiss hospitals were enrolled in the AMIS Plus registry. Large tertiary teaching institutions with 24 hour/7 day cardiac catheterization facilities were classified as type A hospitals, all others as type B. One-year outcome was studied in a subgroup of patients admitted after 2005. Multivariate logistic regression models were used to calculate the odds ratios (OR with 95%CI) for independent predictors of mortality and major adverse cardiac events (MACE).Results: There were 11 type A hospitals with admissions of 15,987 (52%) patients and 65 type B hospitals with 15,023 (48%) patients. Patients initially admitted into B hospitals were older, more frequently female, hypertensive and diabetic, had more severe comorbidities and more frequently NSTE-ACS/UA. They were less likely to receive aspirin, clopidogrel and GPIIb/IIIa antagonists. STE-ACS patients initially admitted into B hospitals received more thrombolysis than those admitted into A hospitals, but less percutaneous coronary intervention (PCI). From the patients admitted to B hospitals, 5271 (35%) were transferred for intervention. Crude in-hospital mortality and MACE were higher in patients from B hospitals. Crude 1-year mortality of 3747 ACS patients followed up was higher in patients initially admitted into B hospitals, but no differences were found for MACE. Hospital type, after adjustment for age, risk factors, type of ACS and co-morbidities, was not an independent predictor of in-hospital mortality (OR 0.94; 0.76-1.16), in-hospital MACE (0.98; 0.82-1.17), 1-year mortality or 1-year MACE (1.06; 0.85-1.33). Analysis of the time of admission indicated a crude outcome in favor of hospitalization during duty-hours but no significant effect could be documented for 1-year outcome.Conclusion: ACS patients admitted to type B hospitals were older, had more severe co-morbidities, more NSTEACS and received less intensive treatment. However, after correcting for baseline inequalities, early and mid-term outcomes were similar regardless of hospital type. Ultimate patient outcome thus does not appear to be influenced by the type of hospital where the initial admission takes place. Appropriate early referral of selected patients probably partly explains this finding.

Contrôle d'une épidémie d'entérocoques résistant à la vancomycine dans plusieurs hôpitaux de Suisse romande [Control of an outbreak of vancomycin-resistant enterococci in several hospitals of western Switzerland].

An outbreak of vancomycin-resistant enterococci (VRE) occurred in 2011 in several hospitals of western Switzerland. Given that VRE can spread rapidly within hospitals and due to the potential transfer of resistance genes to other nosocomial pathogens like MRSA, stringent control measures were implemented. Excellent coordination of control measures between partner healthcare settings was successful in stopping the outbreak.

Diabète de type 2: n'oubliez pas les troubles du comportement alimentaire [Patient with type 2 diabetes: don't forget eating disorders!]

The coexistence of diabetes and eating disorder (ED) is more prevalent than we think; indeed it seems to occur in 10 to 20% of cases. Therefore ED deserve attention to be detected and treated in order to permit a decreased in morbidity and better outcomes in body weight loss. The association of type 2 diabetes and ED is frequently seen in younger, overweighed or obese patients suffering of at least one psychiatric co-morbidities and frequently in a difficult psychosocial setting. To succeed in ED treatment, a multidisciplinary and specialised team in eating disorder is requested, however these patients are highly fragile and complex and therapeutic failure has to be feared.
