Feasibility of 24 h continuous-infusion cefiderocol administered by elastomeric pump in attaining an aggressive PK/PD target in the treatment of NDM-producing Klebsiella pneumoniae otomastoiditis
Stella Babich and others
Objectives Cefiderocol has emerged as a key treatment for managing MDR infections, and its time-dependent pharmacodynamics are optimized by prolonged infusion to maintain time above the MIC ( T > MIC ). Whereas recent stability studies have shown cefiderocol remains stable up to 72 h in ...
Pharmacodynamics of aztreonam/ceftazidime/avibactam and polymyxin B versus New Delhi MBL-producing Acinetobacter baumannii
Jacob T Dumbleton and others
Background Acinetobacter baumannii has become an increasingly urgent public health concern among global health agencies due to high rates of carbapenem resistance. Carbapenem-resistant A. baumannii (CRAB) that express both oxacillinases and MBLs is especially problematic due to resistance to all ...
The S862C amino acid change in CpMrr1 confers fluconazole resistance in Candida parapsilosis
Iacopo Franconi and others
Background Candida parapsilosis is an opportunistic pathogen with increasing rates of resistance to fluconazole and voriconazole. Recently, in an outbreak at the Azienda Ospedaliero-Universitaria Pisana, a new amino acid substitution, S862C in the CpMrr1 protein, was found only in azole-resistant ...
Significant reduction in antibiotic prescription rates in Japan following implementation of the national action plan on antimicrobial resistance (2016–20): a 9-year interrupted time-series analysis
Hideki Hashimoto and others
Background Research on the effectiveness of Japan’s national action plan on antimicrobial resistance, including among individuals with HIV, remains scarce. Objectives To evaluate the impact of policies on antibiotic prescription practices. Methods Outpatient oral antibiotic prescription data from ...
AMRrounds: Carbapenem-resistant Acinetobacter baumannii in the intensive care unit—when resistance meets severity
Davide Mangioni and others
A 65-year-old male with asthma and bronchiectasis was admitted to our hospital for mild respiratory exacerbation. At the time, the ward of admittance was handling a carbapenem-resistant Acinetobacter baumannii (CRAB) outbreak, and the patient underwent collection of surveillance swabs upon ...

Extended-spectrum β-lactamases: an update on their characteristics, epidemiology and detection
Extended-spectrum β-lactamase (ESBL)-producing Gram-negative pathogens are a major cause of resistance to expanded-spectrum β-lactam antibiotics. Since their discovery in the early 1980s, they have spread worldwide and an are now endemic in Enterobacterales isolated from both hospital-associated and community-acquired ...

Sulbactam for carbapenem-resistant Acinetobacter baumannii infections: a literature review
Carbapenem-resistant Acinetobacter baumannii (CRAB) is characterized as a critical priority pathogen with restricted therapeutic options. To date, the most effective antimicrobial treatment against this difficult-to-treat bacterial strain has not been established. Sulbactam is a β-lactamase inhibitor with intrinsic ...

Antibiotic duration for common bacterial infections—a systematic review
Background Reducing antibiotic duration is a key stewardship intervention to mitigate antimicrobial resistance (AMR). We examined current evidence informing antibiotic duration for common bacterial infections to identify any gaps in terms of settings, patient populations and infectious conditions. Trial methodologies were ...

The social burden of antimicrobial resistance: what is it, how can we measure it, and why does it matter?
Antimicrobial resistance (AMR) is a growing global health threat, which is increasingly quantified in terms of its human health and economic burden. In this article, we highlight that for policy and planning purposes the social burden of AMR is as important to attend to as health and economic burdens, requiring systematic ...
