Antibiotiques chez le patient insuffisant rénal : actualisation des adaptations posologiques à la pratique clinique en infectiologie

Antibiotic prescription in chronic kidney disease patients poses a twofold problem. The appropriate use of antibacterial agents is essential to ensure efficacy and to prevent the emergence of resistance, and dosages should be adapted to the renal function to prevent adverse effects. SiteGPR is a French website for health professionals to help with prescriptions to chronic kidney disease patients. A working group of infectious disease specialists and nephrology pharmacists reviewed the indications, dosing regimens, administration modalities, and dose adjustments of antibiotics marketed in France for patients with renal failure. Data available on the SiteGPR website and detailed in the present article aims to provide an evidence-based update of infectious disease recommendations to health professionals managing patients with chronic kidney disease

Le coût des centrales nucléaires ; essai de comparaison entre la France et les Etats-Unis

La comparaison, même grossière, des coûts d'investissement des centrales nucléaires que l'on trouve dans la littérature concernant la France et les Etats-Unis ne peut être abordée sans une certaine réflexion. Alors qu'aux Etats-Unis ces montants correspondent à la dépense totale en monnaie courante, en France ils ne s'appliquent qu'à une évaluation destinée à justifier la réalisation au niveau de la planification nationale, en comparant sa rentabilité à celle de réalisations de nature différente (centrales au charbon, installations hydrauliques ou énergies nouvelles), sur des bases « normatives » (ou pseudo-fictives). Les auteurs montrent comment une comparaison est cependant possible : l'écart d'un facteur voisin de 2 entre les montants trouvés dans la littérature provient de la prise en compte des habitudes comptables différentes et des conséquences de l'inflation observée actuellement

A propos d'une radiation infrarouge très intense dans la lumière du ciel nocturne

Les auteurs rappellent qu'ils ont été les premiers à observer, dans le ciel nocturne, la radiation 1,04 μ ; ils discutent son identification et les conditions de son émission

Electron optics

Electron Optics, Second English Edition, Part I: Optics is a 10-chapter book that begins by elucidating the fundamental features and basic techniques of electron optics, as well as the distribution of potential and field in electrostatic lenses. This book then explains the field distribution in magnetic lenses; the optical properties of electrostatic and magnetic lenses; and the similarities and differences between glass optics and electron optics. Subsequent chapters focus on lens defects; some electrostatic lenses and triode guns; and magnetic lens models. The strong focusing lenses and pri

Effects of time to appropriate treatment and impact of antimicrobial management team are discussed in terms of outcome of BSI. We sought to evaluate the impact of initial BSI management on short-term mortality. Patients and methods: A prospective, multicenter survey was conducted in 121 French hospitals. Participants declaring BSI during a 1-month period were included consecutively. Data on patient comorbidities, illness severity, BSI management, and resistance profile of bacterial strains were collected. Predictors of 10-day mortality were identified by multivariate regression for overall BSI, health care-related and hospital-acquired BSI. Results: We included 1,952 BSIs. More than a third of them were hospital acquired (39%). Multidrug resistance was identified in 10% of cases, mainly in health care-related BSI. Empirical therapy and targeted therapy were appropriate for 61% and 94% of cases, respectively. Increased 10-day mortality was associated with severe sepsis, septic shock, increasing age, and any focus other than the urinary tract. Decreased mortality was associated with receiving at least one active antibiotic within the first 48 hours. Intervention of antimicrobial management team during the acute phase of BSI was associated with a decreased mortality at day 10 in the overall population and in health care-related BSI. Conclusion: Optimizing BSI management by increasing rapidity of appropriate treatment initiation may decrease short-term mortality, even in countries with low rate of multidrug-resistant organisms. Early intervention of antimicrobial management team is crucial in terms of mortality. Keywords: mortality, bloodstream infections, antimicrobial management team, community-acquired infection, health care-related infectio

Application of guidelines for aminoglycosides use in French hospitals in 2013–2014

on behalf of the Société de Pathologie Infectieuse de Langue Française (SPILF), the Observatoire National de l’Epidémiologie de la Résistance Bactérienne aux Antibiotiques (ONERBA) and the Surveillance de la Prescription des Antibiotiques (SPA) groupInternational audienceIn 2011, the French Agency for Safety of Health Products issued guidelines underlining the principles of proper aminoglycosides’ use. The aim of the survey was to evaluate adherence to these guidelines two years after their issue. Characteristics of patients receiving aminoglycosides were recorded by voluntary facilities during a 3-month survey in 2013–2014. The modalities of aminoglycosides treatment were analysed by comparison with the French guidelines. A total of 3,323 patients were included by 176 facilities. Patients were mainly hospitalized in medical wards (33.0%), and treated for urinary-tract infections (24.7%). Compliance regarding the clinical indication and the daily aminoglycosides dose was observed in 65.2% and 62.9% of the cases, respectively. A 30-min once-daily IV administration was recorded in 62.5% of the cases. Aminoglycosides treatment duration was appropriate (≤5 days) for 93.6% of the patients. When considering the four criteria together, 23.2% of the patients had a treatment regimen aligned with the guidelines. Requests for measurements of peak and trough AG serum concentrations matched the guidelines in 24.9% and 67.4% of the cases, respectively. Two years after guidelines issue, aminoglycosides use remains unsatisfactory in French health-care facilities. Efforts should be made for guidelines promotion, especially regarding the issue of underdosing
