Abstract Objectives In pediatric patients, vancomycin plays a pivotal role in combating infections, necessitating precise therapeutic drug monitoring to ensure efficacy and safety. The adoption of model-informed precision dosing (MIPD) has demonstrated potential optimizing strategies based on the area under concentration-time curve (AUC24h). However, predictive performance population pharmacokinetic models using only trough concentrations estimate AUC24h not been evaluated. Methods...

Sepsis affects approximately 8% of pediatric intensive care unit (PICU) admissions in high-income countries. Ceftriaxone, a broad-spectrum beta-lactam antibiotic, is widely used for treating severe infections and bacterial meningitis children. Despite its frequent use, limited studies address the population pharmacokinetic (popPK) ceftriaxone pediatrics. External validation popPK models essential to confirm their suitability individualized dosing PICU patients, enabling selection model best...

Abstract Background There is a lack of evidence on oral amoxicillin pharmacokinetics and exposure in neonates with possible serious bacterial infection (pSBI). We aimed to describe disposition following intravenous administration provide dosing recommendations for preterm term treated pSBI. Methods In this pooled-population pharmacokinetic study, 3 datasets were combined nonlinear mixed-effects modeling. order evaluate administration, profiles different regimens simulated the developed...

175 Background: In its early stages, gastric cancer symptoms are frequently lacking, resulting in an often late and incurable diagnosis. A non-invasive, cheap, reliable screening method for could improve outcomes increase the number of surgically resectable cancers. Breath analysis has emerged as experimental non-invasive identification individuals suitable confirmatory, diagnostic upper gastrointestinal endoscopy. We aimed to evaluate accuracy applicability breath detection adults. Methods:...
