Truncation of GdpP mediates β-lactam resistance in clinical isolates of Staphylococcus aureus.

, 2019
OBJECTIVES: High-level β-lactam resistance in MRSA is mediated in the majority of strains by a mecA or mecC gene. In this study, we identified 10 mec gene-negative MRSA human isolates from Austria and 11 bovine isolates from the UK showing high levels of

Benefits and Harms of Antenatal/Intrapartum Screening for Maternal Group B Streptococcus and Use of Intrapartum Antibiotic Prophylaxis Versus Risk‐Based Protocols or No Intervention: A Rapid Review

Acta Paediatrica, EarlyView.
ABSTRACT Aim To synthesise evidence on the effectiveness, harms and benefits of different approaches to prevent early‐onset Group B Streptococcus (EOGBS) and identify gaps in short and longer‐term outcomes. Methods A two‐phase rapid review. Phase 1 included an overview of systematic reviews (SRs).

Cooperative resistance varies among β-lactamases in E. coli, with some enabling cross-protection and sustained extracellular activity

Communications Biology
β-lactamases confer bacteria resistance to β-lactam antibiotics, and interestingly, this protective effect can extend to neighboring susceptible cells. However, knowledge of this cooperative resistance remains limited.

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Quality and Consistency of Penicillin Allergy Delabelling Guidelines: A Systematic Review

Clinical &Experimental Allergy, EarlyView.
Eighteen penicillin allergy delabelling guidelines from 12 countries were reviewed. There is consensus for staged risk‐based testing, with emerging support for direct oral challenge in low‐risk patients and expanded non‐specialist roles. Overall guideline quality was low, with major gaps in methodological rigour, stakeholder involvement, and ...

Analysis of two Nocardia brasiliensis class A β-lactamases (BRA-1 and BRS-1) and related resistance to β-lactam antibiotics

Journal of Global Antimicrobial Resistance
: Objective: Molecular determinants of β-lactam resistance are poorly explored for most Nocardia species, such as Nocardia brasiliensis. In this study, we characterised resistance mediated by two β-lactamases in the reference strain N.

An Efficient Computational Assay for β-Lactam Antibiotic Breakdown by Class A β-Lactamases

, 2019
Breakdown of β-lactam antibiotics by β-lactamases is one of the most common resistance mechanisms against these drugs. Here, we present a computationally efficient combined quantum mechanics/molecular mechanics simulation protocol for hydrolysis of the β-

Patch Testing in Paediatric Drug Hypersensitivity Reactions: Current Evidence and Clinical Implications

Contact Dermatitis, EarlyView.
ABSTRACT Drug hypersensitivity reactions (DHRs) are common in children and are diagnostically challenging, with cutaneous manifestations being the most common presentation. Patch testing (PT) is a well‐established tool for investigating delayed T‐cell‐mediated reactions and is widely used in patients with contact dermatitis.

Cefepime Combined with Late-Generation β-Lactamase Inhibitors: Mechanisms of Action, In Vitro Activity, PK/PD Characteristics, Clinical Evidence and Resistance Mechanisms

Antibiotics
Cefepime combined with late-generation β-lactamase inhibitors—enmetazobactam, zidebactam, and taniborbactam—represents a promising strategy to treat multidrug-resistant Gram-negative infections.

Cryo‐EM structures of multiple‐peptide resistance factor (MprF) from Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
Cryo‐EM analysis of MprF from Pseudomonas aeruginosa reveals a dimeric enzyme, distinct from Rhizobium homologues. The soluble GNAT domain contains a dynamic amphipathic helix (TTH) that adopts different positions in detergent micelle and nanodisc, relative to the membrane.
