Cefepime exposure in prolonged or intermittent infusion in critically ill children

British Journal of Clinical Pharmacology, EarlyView.
Aims Cefepime is commonly used in critically ill children for whom there is a high between‐subject variability. To reach the therapeutic pharmacokinetic (PK) target in critically ill patients, prolonged infusion of beta‐lactams seems to be the most efficient.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Impact of beta-lactam allergy labels on bone marrow transplant patients

Antimicrobial Stewardship & Healthcare Epidemiology
Background: Approximately 95% of patients with a beta-lactam allergy noted in their medical record are not truly allergic when tested. These patients may unnecessarily avoid first-line antibiotics, resulting in increased treatment failure, higher costs ...

N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

Chemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.

Designing a Triplet 2‐Formylphenylnitrene With Fast Tunneling Reactivity

Chemistry – A European Journal, EarlyView.
A 3‐CF3 substituent accelerates tunneling in triplet 2‐formylphenylnitrene, making its reactivity in cryogenic matrices too fast for conventional IR spectroscopic detection. Bringing this chemistry to low‐temperature solutions allows suppression of intrinsic nitrene dimerization through faster cyclization, which even outcompetes the 1,4‐H shift ...

Clinical Model‐Informed Precision Dosing Consult Service for Accelerating Personalized Medication in Pediatric Patients

Clinical Pharmacology &Therapeutics, EarlyView.
Traditional dosing strategies often rely on a “one‐size‐fits‐all” paradigm, assuming an “average” patient with typical demographic and pharmacological characteristics. In reality, this often overlooks existing between‐patient variability and can lead to suboptimal drug exposure or toxicity. This issue is especially pronounced in pediatric patients, who

The Effect of Dicloxacillin Administration on Pharmacokinetics of Narrow Therapeutic Window Drugs: Phenytoin and Warfarin

Clinical Pharmacology &Therapeutics, EarlyView.
Dicloxacillin is a penicillinase‐resistant beta‐lactam antibiotic and potent activator of the Pregnane X receptor (PXR), known to induce CYP2C9, CYP2C19, and CYP3A4 activity. Clinical data suggest it reduces anticoagulation in warfarin‐treated patients and increases the risk of thromboembolic events.
