National Cohort of Compassionate Use of Meropenem-Vaborbactam: No Benefit over Meropenem for .

Background: Meropenem-vaborbactam (MEM-VAB) is a novel carbapenem-beta-lactamase-inhibitor combination that demonstrates activity against carbapenem-resistant (CR) Gram-negative bacteria, and more specifically KPC-producers, since vaborbactam is an effective inhibitor of KPC enzymes in vitro. This study aimed to describe the initial uses and efficacy of MEM-VAB for compassionate treatment during the first 21 months following its early access in France.

Background: The clinical course and outcome of COVID-19 vary widely, from asymptomatic and mild to critical. Elderly patients and patients with comorbidities are at increased risk of respiratory failure and oxygen requirements. Due to the massive surge, the pandemic has created challenges for overwhelmed hospitals.

Real-life impact of respiratory panel PCR assay on antibiotic prescription in geriatric acute care in the pre-COVID-19 era.

Objectives: In this era of bacterial resistance, avoiding inappropriate use of antibiotic treatments is of major importance. Respiratory tract infections are frequent among older patients, and differentiating viral from bacterial infections is a challenge. The aim of our study was to evaluate the impact of recently available respiratory PCR testing on antimicrobial prescription in geriatric acute care.

Short Antibiotic Treatment Duration for Osteomyelitis Complicating Pressure Ulcers: A Quasi-experimental Study.

Background: Osteomyelitis-complicating pressure ulcers are frequent among patients with spinal cord injuries (SCIs), and the optimal management is unknown. In our referral center, the current management is debridement and flap coverage surgeries, followed by a short antibiotic treatment. We aimed to evaluate patients' outcomes a year after surgery.

[Excess mortality in nursing homes during the first wave of the Covid-19 pandemic].

Overall mortality in France is 147 568 deaths since the first wave. Although accounting for nearly 20% of deaths in France, the excess mortality in long-term care facilities compared to previous years has not been fully studied. The Covid-19 pandemic has highlighted the vulnerability of residents in long-term care facilities, with highly dependent elderly patients being the most exposed to the risk of death, with deleterious effects linked to the effects of confinement, which in Ehpad has resulted in major isolation of residents and the appearance by care teams of cognitive disorders appearing or deteriorating in residents, as well as a significant loss of autonomy.

Antibiotic Consumption and Bacterial Resistance Rates in Hospitalized COVID-19 Patients: A Retrospective Study During the 3 First Surges.

In our hospital, during COVID-19 pandemic, overall consumption of antibiotics increased during the three first surges, mainly due to ICU prescription However, antibiotic consumption decreased in the Infectious Diseases Department. Rates of ESBL Enterobacterales remained stable.

Real-life temocillin use in Greater Paris area, effectiveness and risk factors for failure in infections caused by ESBL-producing Enterobacterales: a multicentre retrospective study.

Background: Temocillin is a β-lactam that is not hydrolysed by ESBLs.

Hyaluronic Acid and Chondroitin Sulphate Treatment for Recurrent Severe Urinary Tract Infections due to Multidrug-Resistant Gram-Negative Bacilli in a Patient With Multiple Sclerosis: Case Report and Literature Review.

Urinary tract infections (UTIs) are the most common bacterial infections in patients with neurogenic lower urinary tract dysfunction. Antibiotic options for prophylaxis or curative treatment in case of recurrent UTIs, especially due to multidrug-resistant organisms (MDRO), are scarce. We present the case of a 72-year-old man with neurogenic lower urinary tract dysfunction and history of frequent recurrent UTIs due to multiple MDROs who was successfully treated with hyaluronic acid (HA) and chondroitin sulfate (CS) bladder instillations.

Discontinuing β-lactam treatment after 3 days for patients with community-acquired pneumonia in non-critical care wards (PTC): a double-blind, randomised, placebo-controlled, non-inferiority trial.

Background: Shortening the duration of antibiotic therapy for patients admitted to hospital with community-acquired pneumonia should help reduce antibiotic consumption and thus bacterial resistance, adverse events, and related costs. We aimed to assess the need for an additional 5-day course of β-lactam therapy among patients with community-acquired pneumonia who were stable after 3 days of treatment.

Methods: We did this double-blind, randomised, placebo-controlled, non-inferiority trial (the Pneumonia Short Treatment [PTC]) in 16 centres in France.

Bloodstream infections in older population: epidemiology, outcome, and impact of multidrug resistance.

Bloodstream infections (BSIs) among older patients are frequent with high rate of mortality. Infections with multidrug-resistant organisms (MDRO) are associated with higher mortality than with susceptible microorganisms. We aimed to evaluate the prevalence of MDRO infection during BSI in older population and the factors associated with unfavorable outcome.
