Endoscopic Screening for Laryngotracheal Complications in Children Following Prolonged Mechanical Ventilation Maintained Through Endotracheal Intubation: A Cross-Sectional Pilot Project.

Background: An endoscopic screening program following successful weaning from prolonged mechanical ventilation maintained through endotracheal tube (ET; ) may be justified to assess the upper (laryngotracheal) airway in children who may not always be symptomatic for intubation-related complications.

Objectives: To evaluate effects of prolonged intubation in children through endoscopic screening of the laryngotracheal airway.

Methods: In this cross-sectional pilot project, children (2 months-12 years) successfully extubated following prolonged intubation were selected, irrespective of having symptoms, for a 1-time flexible nasolaryngoscopy at third to sixth month post-extubation (follow-up window).

Voltage-Controlled Magnetic Anisotropy in FeCo/Pd/MgO system.

Voltage-controlled magnetic anisotropy (VCMA) in an epitaxially grown Fe/FeCo/Pd/MgO system was investigated using spin-wave spectroscopy. The spin-wave resonant frequency linearly depended on the bias-voltage. The resonant-frequency shift increased with the Co fraction in FeCo/Pd.
