[Establishment of a population pharmacokinetic model for linezolid in neonates with sepsis].

Objectives: To establish the pharmacokinetic model of linezolid in neonates, and to optimize the administration regimen.

Methods: A prospective study was conducted among 64 neonates with sepsis who received linezolid as anti-infective therapy, and liquid chromatography-tandem mass spectrometry was used to measure the plasma concentration of the drug. Clinical data were collected, and nonlinear mixed effects modeling was used to establish a population pharmacokinetic (PPK) model.

The clinical characteristics and risk factors analysis within one week before the onset of necrotizing enterocolitis.

There are considerable researches on risk factors for necrotizing enterocolitis (NEC), focusing primarily on the entire course before onset. However, fewer studies address risk factors within the brief period before NEC occurrence. The current study aims to retrospectively analyze the clinical data of NEC patients while focusing on relevant risk factors in the preceding week of NEC onset.

N-Acetylcysteine Alleviates Necrotizing Enterocolitis by Depressing SESN2 Expression to Inhibit Ferroptosis in Intestinal Epithelial Cells.

Abstract-Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease in neonates, and effective strategies to prevent and treat NEC are still lacking. Studies have shown that N-acetylcysteine (NAC) has protective effects against NEC, however, the specific mechanism underlying its effects on intestinal functions remains unclear. Recently, NAC has been shown to suppress ferroptosis in many diseases, while it is unclear whether the beneficial effects of NAC on NEC are related to ferroptosis.

Deep learning-assisted ultra-accurate smartphone testing of paper-based colorimetric ELISA assays.

Smartphone has long been considered as one excellent platform for disease screening and diagnosis, especially when combined with microfluidic paper-based analytical devices (μPADs) that feature low cost, ease of use, and pump-free operations. In this paper, we report a deep learning-assisted smartphone platform for ultra-accurate testing of paper-based microfluidic colorimetric enzyme-linked immunosorbent assay (c-ELISA). Different from existing smartphone-based μPAD platforms, whose sensing reliability is suffered from uncontrolled ambient lighting conditions, our platform is able to eliminate those random lighting influences for enhanced sensing accuracy.

Circular RNAs expression profiles and bioinformatics analysis in bronchopulmonary dysplasia.

Background: Bronchopulmonary dysplasia (BPD) has long been considered the most challenging chronic lung disease for neonatologists and researchers due to its complex pathological mechanisms and difficulty in prediction. Growing evidence indicates that BPD is associated with the dysregulation of circular RNAs (circRNAs). Therefore, we aimed to explore the expression profiles of circRNAs and investigate the underlying molecular network associated with BPD.

The development and validation of a predictive model for neonatal phototherapy outcome using admission indicators.

Delayed exchange transfusion therapy (ETT) after phototherapy failure for newborns with severe hyperbilirubinemia could lead to serious complications such as bilirubin encephalopathy (BE). In this current manuscript we developed and validated a model using admission data for early prediction of phototherapy failure. We retrospectively examined the medical records of 292 newborns with severe hyperbilirubinemia as the training cohort and another 52 neonates as the validation cohort.
