Ansa Cervicalis-To-Phrenic Nerve Transfer: Technical Note With Potential Application For Diaphragmatic Reanimation In Patients With High Cervical Spinal Cord Injury, Jonathan Melnick, Mohammadali M. Shoja, Gary B. Schwartz Nov 2024

Ansa Cervicalis-To-Phrenic Nerve Transfer: Technical Note With Potential Application For Diaphragmatic Reanimation In Patients With High Cervical Spinal Cord Injury, Jonathan Melnick, Mohammadali M. Shoja, Gary B. Schwartz

HCA-NSU MD Research Day

Objective. This study was conducted to determine whether utilization of the superior root of ansa cervicalis (SRAC) as the donor for phrenic nerve (PN) transfer is technically feasible. Background. In patients with high cervical spinal cord injury resulting in diaphragmatic paralysis, another donor, the spinal accessory nerve, has been used successfully to reinnervate the PN and restore diaphragmatic function. Methods. Eight neck sides underwent cadaveric surgery. The sternocleidomastoid muscle was retracted posteriorly, the SRAC and PN were isolated, and the SRAC was cut near its distal end and transposed to the ipsilateral PN as it crossed the anterior scalene muscle. …

Seizure Prediction In Epilepsy Patients, Gary Dean Cravens Feb 2022

Seizure Prediction In Epilepsy Patients, Gary Dean Cravens

NSU REACH and IPE Day

Purpose/Objective: Characterize rigorously the preictal period in epilepsy patients to improve the development of seizure prediction techniques. Background/Rationale: 30% of epilepsy patients are not well-controlled on medications and would benefit immensely from reliable seizure prediction. Methods/Methodology: Computational model consisting of in-silico Hodgkin-Huxley neurons arranged in a small-world topology using the Watts-Strogatz algorithm is used to generate synthetic electrocorticographic (ECoG) signals. ECoG data from 18 epilepsy patients is used to validate the model. Unsupervised machine learning is used with both patient and synthetic data to identify potential electrophysiologic biomarkers of the preictal period. Results/Findings: The model has shown states corresponding to …
