Neurally adjusted ventilatory assist (NAVA) in neonatal and pediatric critical care-A scoping review of randomized controlled trials.

We Aimed to analyze for which indications neurally adjusted ventilatory assist (NAVA) has been studied in pediatric patients by conducting a scoping review. PubMed, Scopus, and Web of Science databases were searched in September 2023. We included all randomized trials (including crossover, parallel, and cluster) comparing NAVA to other invasive ventilation modalities in children aged <18 years.

The bottleneck stent model for chronic myocardial ischemia and heart failure in pigs.

A large animal model of chronic myocardial ischemia and heart failure is crucial for the development of novel therapeutic approaches. In this study we developed a novel percutaneous one- and two-vessel model for chronic myocardial ischemia using a stent coated with a polytetrafluoroethylene tube formed in a bottleneck shape. The bottleneck stent was implanted in the proximal left anterior descending (LAD) or proximal circumflex artery (LCX), or in both proximal LCX and mid LAD 1 wk later (2-vessel model), and pigs were followed for 4-5 wk.
