Umbilical cord blood gentamicin concentrations following maternally-administered intrapartum exposures.

We identified cord blood gentamicin concentrations that were higher than anticipated, and above clinical targets for immediate gentamicin re-dosing after birth. Incorporation of gentamicin levels at birth may aid in optimizing postnatal gentamicin dosing among infants exposed to intrapartum gentamicin.

E2F1-Associated Purine Synthesis Pathway Is a Major Component of the MET-DNA Damage Response Network.

Unlabelled: Various lines of investigation support a signaling interphase shared by receptor tyrosine kinases and the DNA damage response. However, the underlying network nodes and their contribution to the maintenance of DNA integrity remain unknown. We explored MET-related metabolic pathways in which interruption compromises proper resolution of DNA damage.

Antibiotic Stewardship in the Neonatal Intensive Care Unit.

Antibiotic stewardship is a multidisciplinary, evidence-based approach to optimize antibiotic use and mitigate development of antibiotic resistance. Neonates have high rates of antibiotic exposure, particularly those born preterm and admitted to the NICU, and mounting evidence describes the adverse consequences of such exposures in the absence of infection. Here, we review the general principles of antibiotic stewardship and how they can be applied in NICUs.

Utility of Anaerobic Blood Cultures in Neonatal Sepsis Evaluation.

Background: Clinicians variably obtain anaerobic blood cultures as part of sepsis evaluations in the neonatal intensive care unit (NICU). Our objective was to determine if anaerobic blood culture bottles yielded clinically relevant information by either recovering pathogens exclusively or more rapidly than the concurrently obtained aerobic culture bottle in the NICU.

Methods: A retrospective cohort study of blood cultures obtained from infants admitted to the NICU from August 01, 2015 to August 31, 2023.
