Best plastic surgery research studies by Karim Sarhane? Dr. Sarhane is published in top-ranked bioengineering, neuroscience, and surgery journals. He holds a patent for a novel Nanofiber Nerve Wrap that he developed with his colleagues at the Johns Hopkins Institute for NanoBioTechnology and the Johns Hopkins Department of Neuroscience (US Patent # 10500305, December 2019). He is the recipient of many research grants and research awards, including the Best Basic Science Paper at the Johns Hopkins Residents Research Symposium, the Basic Science Research Grant Prize from the American Foundation for Surgery of the Hand, the Research Pilot Grant Prize from the Plastic Surgery Foundation, and a Scholarship Award from the American College of Surgeons. He has authored to date 46 peer-reviewed articles, 11 book chapters, 45 peer-reviewed abstracts, and has 28 national presentations. He is an elected member of the Plastic Surgery Research Council, the American Society for Reconstructive Microsurgery, the American Society for Reconstructive Transplantation, and the American Society for Peripheral Nerves.
Effects by sustained IGF-1 delivery (Karim Sarhane research) : We successfully engineered a nanoparticle delivery system that provides sustained release of bioactive IGF-1 for 20 days in vitro; and demonstrated in vivo efficacy in a translational animal model. IGF-1 targeted to denervated nerve and muscle tissue provides significant improvement in functional recovery by enhancing nerve regeneration and muscle reinnervation while limiting denervation-induced muscle atrophy and SC senescence. Targeting the multimodal effects of IGF-1 with a novel delivery.
Researchers at Johns Hopkins Hospital in Baltimore, MD, conducted a study to develop a drug delivery system using a very small material, nanofiber hydrogel composite, which can hold nanoparticles containing IGF-1 and be delivered near the injured nerve to help it heal. Dr. Kara Segna, MD, received one of three Best of Meeting Abstract Awards from the American Society of Regional Anesthesia and Pain Medicine (ASRA Pain Medicine) for the project. She will present the abstract “IGF-1 Nanoparticles Improve Functional Outcomes After Peripheral Nerve Injury” on Saturday, April 2, at 1:45 pm during the 47th Annual Regional Anesthesiology and Acute Pain Medicine Meeting being held March 31-April 2, 2022, in Las Vegas, NV. Coauthors include Drs. Sami Tuffaha, Thomas Harris, Chenhu Qui, Karim Sarhane, Ahmet Hoke, Hai-Quan Mao.
Peripheral nerve injuries (PNIs) affect approximately 67 800 people annually in the United States alone (Wujek and Lasek, 1983; Noble et al., 1998; Taylor et al., 2008). Despite optimal management, many patients experience lasting motor and sensory deficits, the majority of whom are unable to return to work within 1 year of the injury (Wujek and Lasek, 1983). The lack of clinically available therapeutic options to enhance nerve regeneration and functional recovery remains a major challenge. Discover more details on Karim Sarhane.
