The long-term disposition of gentamicin (up to 100-240 h) was studied in 13 premature newborns (33 weeks mean gestational age) and in 7 infants and children (1 month to 8 years). The data fitted bi- or triexponential curves with terminal half-lives averaging 51 and 37 h. Newborns showed lower values of body clearance, central compartment and steady state volumes of distribution than infants and children (respectively, 12.8 vs. 50.4 ml/min/1.73 m2, 9.03 vs. 17.5 liters/1.73 m2, and 15.7 vs. 35.5 liters/1.73 m2). The ratio between the amount of gentamicin predicted at steady state in the tissue compartment and in the total body was also significantly lower in newborns than in the older group (0.4 vs. 0.52). These data provide pharmacokinetic demonstration of an age dependence in gentamicin tissue distribution and excretion during the early stages of human development.

Acute rhinosinusitis (ARS) in children may be accompanied by acute otitis media (AOM) which is often associated with bacterial co-infections. These conditions are among the primary reasons that children visit hospitals and require antibiotic treatment. This study evaluated the efficacy of the nasal-spraying probiotics (LiveSpo Navax containing 5 billion Bacillus subtilis and B.

It has been demonstrated that SARS-CoV-2 variants escape neutralizing immunity elicited by previous infection and/or vaccination, leading to new infection waves and cases of reinfection. The study aims to gain into cases of reinfections, particularly infections and/or vaccination-induced protection.

Purpose: We aimed to analyze regional variations in the assignment of (ICD-10) codes to acute respiratory infections, seeking to identify notable anomalies that suggest diverse diagnoses of the same condition.
Methods: We analyzed national weekly diagnosis data for acute respiratory infections (ICD-10 codes J00-J22) in Poland from 2010 to 2019, covering all 380 county-equivalent administrative regions and encompassing 292 million consultations. Data were aggregated into age brackets.

Odor perception plays a critical role in early human development, but the underlying neural mechanisms are not fully understood. To investigate these, we presented appetitive and aversive odors to infants of both sexes at one month of age while recording functional magnetic resonance imaging (fMRI) and nasal airflow data. Infants slept during odor presentation to allow MRI scanning.

Objective: Fetomaternal transfusion (FMT) is associated with increased perinatal mortality and morbidity, but data on postnatal outcomes are scarce. Our aim was to determine the incidence of adverse short-termand long-term sequelae of severe FMT.
