Systematic screening for digestive carriage of extended-spectrum β-lactamase-producing Enterobacterales (E-ESBL) at hospital readmission among patients with past history of E-ESBL colonization or infection.

Background: Extended-spectrum β-lactamase-producing Enterobacterales (E-ESBL) are commensal multidrug-resistant (MDR) bacteria of the digestive tract whose prevalence has risen sharply worldwide and in Europe over the past two decades.

Aim: To assess digestive carriage at hospital readmission of a large cohort of 2509 patients with E-ESBL carriage over a five-year survey; 833 (33%) patients were readmitted at least once.

Methods: A retrospective, single-centre survey conducted at a tertiary care hospital in France.

Retrospective analysis of a large single cohort of Enterobacteriaceae producing extended-spectrum B-lactamase (E-ESBL) patients: incidence, microbiology, and mortality.

We conducted a retrospective study from 2005 to 2019 to describe the epidemiology and mortality of enterobacterial producing extended-spectrum β-lactamase (E-ESBL) infections in our university hospital over a 17-year period of time. Clinical and microbiological data were extracted from different software used for continuous surveillance. Stool samples from systematic screening for E-ESBL colonization were excluded from the study.

Enterobacter cloacae complex outbreak in a neonatal intensive care unit: multifaceted investigations and preventive measures are needed.

We report the investigation to control an Enterobacter cloacae complex outbreak in a neonatal intensive care unit from November 2020 to February 2021. Pulsed-field gel electrophoresis showed that five of eight cases were infected with a clonal strain. Breast pumps, shared among mothers in the unit, could have contributed to the spread of the clonal spread.

Voriconazole topical cream formulation: evidence for stability and antifungal activity.

Systemic use of voriconazole (VCZ) might be restricted by adverse events, such as hepatotoxicity and neurotoxicity, or drug-drug interactions. Topical VCZ application to skin may help to treat local infection more effectively and limit unwanted whole-body exposure. Topical VCZ cream was stable for 90 days when refrigerated.

An original calibration technique for soft x-ray detectors and its use in the Tore Supra tomographic system.

This paper describes in detail the recent progresses which have been made in Tore Supra for developing a new technique of calibration of the soft x-ray (SXR) detectors in the range 1-30 keV. The diode response as a function of the flux of photons resulted accurately linear over almost three orders of magnitude. Apart from a limited number of deficient detectors, promptly replaced with new ones, the spread of the diode responses (84 detectors) is about 20% total of the average value.
