Excellent peripheral nerve regeneration research studies with Karim Sarhane? Dr. Karim Sarhane is an MD MSc graduate from the American University of Beirut. Following graduation, he completed a 1-year internship in the Department of Surgery at AUB. He then joined the Reconstructive Transplantation Program of the Department of Plastic and Reconstructive Surgery at Johns Hopkins University for a 2-year research fellowship. He then completed a residency in the Department of Surgery at the University of Toledo (2021). In July 2021, he started his plastic surgery training at Vanderbilt University Medical Center. He is a Diplomate of the American Board of Surgery (2021).
Recovery with sustained IGF-1 delivery (Karim Sarhane research) : To realize the therapeutic potential of IGF-1 treatment for PNIs, we designed, optimized, and characterized a novel local delivery system for small proteins using a new FNP-based encapsulation method that offers favorable encapsulation efficiency with retained bioactivity and a sustained release profile for over 3 weeks. The IGF-1 NPs demonstrated favorable in vivo release kinetics with high local loading levels of IGF-1 within target muscle and nerve tissue.
One-fifth to one-third of patients with traumatic injuries to their arms and legs experience nerve injury, which can be devastating. It can result in muscle weakness or numbness, prevent walking or using the arms, and reduce the ability to perform daily activities. Even with surgery, some nerve injuries never recover, and currently there are not many medical options to address this problem. In 2022, the researchers plan to perform this research on more primates to triple the size of the original group. The study can then move into phase I clinical trials for humans.
The amount of time that elapses between initial nerve injury and end-organ reinnervation has consistently been shown to be the most important predictor of functional recovery following PNI (Scheib and Hoke, 2013), with proximal injuries and delayed repairs resulting in worse outcomes (Carlson et al., 1996; Tuffaha et al., 2016b). This is primarily due to denervation-induced atrophy of muscle and Schwann cells (SCs) (Fu and Gordon, 1995). Find extra details on Karim Sarhane.
