Laryngeal Injury After Prone Positioning: A Cadaveric Evaluation of Endotracheal Contact Pressures.

Laryngotracheal stenosis (LTS) has been described as a complication of prolonged intubation. Early in the COVID-19 pandemic, many patients were intubated and ventilated for a long period, often in the prone position. To investigate the physical effects of prone versus supine positioning and its possible correlation to LTS, this research used two Thiel-embalmed cadavers, one male and one female, and a novel pressure sensor device, to directly measure the force applied by an endotracheal tube onto the posterior glottis.

Progress in silk and silk fiber-inspired polymeric nanomaterials for drug delivery.

The fields of drug and gene delivery have been revolutionized by the discovery and characterization of polymer-based materials. Polymeric nanomaterials have emerged as a strategy for targeted delivery because of features such as their impressive biocompatibility and improved availability. Use of naturally derived polymers in these nanomaterials is advantageous due to their biodegradability and bioresorption.

Burnout in Certified Anesthesiologist Assistants.

Certified anesthesiologist assistants (CAAs) are Advanced Practice Providers (APPs) within the anesthesia care team. This research evaluated their burnout. CAAs were surveyed nationally about their professional/work characteristics, perceived fairness of salary/benefits compared to certified registered nurse anesthetists/CAAs, the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), the Conditions for Work Effectiveness Questionnaire II, and questions regarding wellness resources at their place of employment.
