Article Synopsis
- * In experiments on mice and human subjects, Dex-CI showed a significant reduction in electrical impedance and inflammatory response compared to standard implants.
- * Locally delivered dexamethasone (Dex-local) was found to be ineffective for long-term improvement, indicating that Dex-CI is a better option than current clinical practices for reducing inflammation and improving implant performance.
The degree of intracochlear trauma and force associated with manual electrode insertion may negatively impact cochlear implant (CI) outcomes and preservation of residual acoustic hearing. Robotics-assisted CI insertion systems have recently been developed to overcome human kinematic constraints associated with manual surgical techniques to allow lower force and slower electrode insertions, with the goal of improving performance and hearing preservation outcomes. The iotaSOFT (iotaMotion Inc.

Tribometry was used to determine the effect of zwitterionic coatings on the lubricity of surfaces with varying hydration levels, applied normal force, and time frame. Additionally, flexural resistance was investigated using mandrel bending.

Objective Pediatric airway emergencies are amongst the most tenuous scenarios faced by on-call providers, requiring quick access to the appropriate equipment and a timely response. In the present study, we report on the testing and improvement of pediatric airway carts at our institution. The primary objective was to optimize our pediatric airway emergency carts to improve response times.
