Purpose: To assess whether oculoplastic surgeries can be performed without any topical and systemic antibiotics, in a "100% antibiotic free" fashion.

Method: We conducted a multicenter retrospective study between November 2017 and December 2022. Patients who underwent an oculoplastic procedure were screened.

is an aerobic Gram-positive coccus that grows as tiny alpha-hemolytic colonies. is a slow-growing facultative anaerobic Gram-positive rod. These bacteria are part of the urogenital microbiota of healthy patients, but can also be involved in urinary tract infections (UTIs), particularly in elderly men and young children.

Objectives: When the COVID-19 pandemic reached France early in 2020, the enforced nationwide lockdown deeply altered lifestyle as well as hospital processes and modalities of care. The aim of the study was to evaluate the impact during the lockdown of the first epidemic wave on the epidemiology of bacteremia in one French University Hospital.

Patients And Methods: Retrospective cohort study including adult patients with positive blood culture between 23 March to 24 May 2020.

Article Synopsis
  • Scientists wanted to see if working all day and night on blood tests would help doctors give medicine faster to patients with infections.
  • They looked at data before and after the continuous workflow changed and found that doctors were able to change antibiotic medicine almost 10 hours faster after the new system was in place.
  • Even though the time to provide effective medicine was shorter, the amount of time patients stayed in the hospital and overall deaths didn’t change.

bloodstream infections are life-threatening and require rapid, targeted antibiotherapy based on antibiotic susceptibility testing (AST). A new method using Muller-Hinton Rapid-SIR (MHR-SIR) agar (i2a, Montpellier, France) allows complete direct AST (dAST) to be read from positive blood culture bottles (BCBs) for all species after 6-8 h of incubation. We evaluated (i) the performance of dAST from positive BCBs on MHR-SIR agar using two different inoculum protocols; (ii) the categorical agreement between dAST results obtained with MHR-SIR agar vs.

Spontaneous bacterial peritonitis (SBP) is a severe infection that requires fast and accurate antibiotic therapy to improve the patient outcome. Direct bacterial identification using MALDI-TOF mass spectrometry from ascitic fluid inoculated in blood culture bottles (BCBs) could therefore improve patients' management. We evaluated the impact of the implementation of this method for the treatment of patients.

Unlabelled: Clindamycin is an antibiotic with high bioavailability and appropriate bone diffusion, often proposed as an alternative in guidelines for prosthetic joint infections. We aimed to evaluate the efficacy of clindamycin in the treatment of shoulder implant joint infections (SIJI).

Methods: A retrospective analysis was conducted at the University Hospital of Nice (France) between 2010 and 2019.

We report here the complete genome sequences of three Bacillus cereus group strains isolated from blood cultures from premature and immunocompromised infants hospitalized in intensive care units in three French hospitals. These complete genome sequences were obtained from a combination of Illumina HiSeq X Ten short reads and Oxford Nanopore MinION long reads.

Objectives: Dalbavancin is a long-lasting lipoglycopeptide active against Gram-positive bacteria, especially methicillin-resistant staphylococci. Few data are available on dalbavancin use for treatment of prosthetic joint infections (PJIs). We describe a cohort of patients treated for PJI with dalbavancin and review the literature regarding this condition.

Dysregulated immune response is the key factor leading to unfavorable coronavirus disease 2019 (COVID-19) outcome. Depending on the pathogen-associated molecular pattern, the NLRP3 inflammasome can play a crucial role during innate immunity activation. To date, studies describing the NLRP3 response during severe acute respiratory syndrome coronavirus 2 infection in patients are lacking.

Nocardia takedensis was first isolated in 2005, from soil in Japan. We report here two cases of lymphangitis in France (2012-2017) caused by N. takedensis both occurring after skin injury while gardening, which enabled its inoculation.

Dalbavancin is a glycopeptide antibiotic with a long half-life, recently marketed in Europe for skin and soft-tissue infections (SSTIs), but its real-life use is not well known. The aim of this study was to describe all first prescriptions in France over an 16-month period. A retrospective study on all adult patients receiving at least one dose of dalbavancin from 1 June 2017 to 31 September 2018 was performed (75 patients from 29 French hospitals).

Background: Urinary tract infections are known to be caused by bacteria, but the potential implications of archaea have never been studied in this context.

Methods: In two different university hospital centres we used specific laboratory methods for the detection and culture of archaeal methanogens in 383 urine specimens prospectively collected for diagnosing urinary tract infection (UTI).

Findings: Methanobrevibacter smithii was detected by quantitative PCR and sequencing in 34 (9%) of the specimens collected from 34 patients.

Matrix-assisted laser desorption ionization-time of flight mass spectrometry is not widely used to identify bacteria directly from positive blood culture bottles (BCBs) because of overlong protocols. The objective of this work was to develop and evaluate a simple extraction protocol for reliable identification from BCBs. The 10-min protocol was applied over a 5-month period.

After the deaths of 2 preterm neonates with Bacillus cereus systemic infection in the same intensive care unit, we investigated the pathogenic potential of this bacterium. Genetic and virulence analysis indicated the neonates were infected with 2 different strains with a virulence potential similar to environmental strains, indicating likely patient immune response failure.

The E3 ubiquitin ligase HACE1 is a potent tumor suppressor that controls cell proliferation and ubiquitylates the small GTPase Rac1 to target it to proteasomal degradation. Whether and how the activity of HACE1 is regulated by the N-terminal ankyrin (ANK) and the middle (MID) domains is ill defined. Here, we identified in the version 64 of the Catalogue of Somatic Mutations in Cancer (COSMIC) 13 missense mutations of hace1 located outside the HECT domain, and found that all lead to defective control of cell proliferation.

Background: Data from next generation sequencing technologies uncovered the existence of many classes of small RNAs. Recent studies reported that small RNAs are released by cells and can be detected in the blood. In this report, we aimed to discover the occurrence of novel circulating small RNAs in coronary artery disease (CAD).
