High-flow nasal cannula versus nasal continuous positive airway pressure on postnatal growth and feeding in preterm infants: a secondary analysis of the NIPPN study.

Objective: High-flow nasal cannula (HFNC) is generally considered to have fewer enteral feeding problems than nasal continuous positive airway pressure (NCPAP) or nasal intermittent positive-pressure ventilation (NIPPV). However, the effects of HFNC on the feeding outcomes in preterm infants are still controversial. The aim of this study was to assess the effect of HFNC on postnatal growth and feeding.

Single-Molecule Oxidoreductase Activity Analysis for Activity-Based Diagnosis Based on Proteoform Alterations.

We developed a single-molecule enzyme activity assay platform for NAD(P)-dependent oxidoreductases, leveraging a new NAD(P)H-responsive fluorogenic probe optimized for microdevice-based fluorometric detection. This platform enabled the detection of enzyme activities in blood and cerebrospinal fluid (CSF), including lactate dehydrogenase, glucose-6-phosphate dehydrogenase, and hexokinases. We demonstrate its potential for activity-based diagnosis by detecting altered populations of enzyme activity species in blood and CSF from liver damage in brain tumor patients.

Preclinical study of novel human allogeneic adipose tissue-derived mesenchymal stem cell sheets toward a first-in-human clinical trial for myopic chorioretinal atrophy.

Background: Mesenchymal stem cells may have neuroprotective and tissue regenerative capabilities and the potential to rescue retinal degeneration in chorioretinal diseases including myopic chorioretinal atrophy. Transplantation of human (allogeneic) adipose tissue-derived mesenchymal stem cell (adMSC) suspensions has been clinically conducted to treat retinal degenerative diseases. However, serious side effects including proliferative vitreoretinopathy and epiretinal membrane formation have been reported.

Temporal dynamics of extended-spectrum β-lactamase-producing Escherichia coli and carbapenemase-producing Gram-negative bacteria in hospital wastewater.

Hospital wastewater is a reservoir for the environmental spread of clinically relevant antimicrobial-resistant bacteria and resistance genes. The aim of this study was to quantify total Escherichia coli, extended-spectrum β-lactamase (ESBL)-producing E. coli, and carbapenemase-producing organisms (CPOs) and perform whole-genome sequencing-based characterization of these bacterial isolates in hospital wastewater samples collected bimonthly in Japan from January to November 2021.
