The epidermal growth factor receptor inhibitor gefitinib enhances in vitro and in vivo sensory axon regeneration and functional recovery following transection in a mouse median nerve injury model.

Introduction: The epidermal growth factor receptor (EGFR; ErbB1), a membrane bound receptor tyrosine kinase, is hypothesized to have an inhibitory influence on peripheral nerve regeneration. This study examines the impact of EGFR inhibition on nerve regeneration using the commercially available small molecule inhibitor gefitinib.

Method: In vitro assays included neurite outgrowth of cultured dorsal root ganglion (DRG) neurons from adult C57Bl/6 wildtype mice on immobilized chondroitin sulfate proteoglycans (CSPG).

"Addressing barriers to digital health readiness among a Latino population".

Objective: There are many potential barriers to an individual's readiness and ability to use telehealth, including technology access, trust and knowledge. This qualitative study was a partnership between Jefferson and Esperanza Health Center (EHC), focused on addressing barriers to digital readiness among the Latino population served by EHC.

Methods: We conducted semi-structured interviews with Latino patients to assess their experiences with technology and willingness to learn more about technology for healthcare.

Infection length and host environment influence on Plasmodium falciparum dry season reservoir.

Persistence of malaria parasites in asymptomatic hosts is crucial in areas of seasonally-interrupted transmission, where P. falciparum bridges wet seasons months apart. During the dry season, infected erythrocytes exhibit extended circulation with reduced cytoadherence, increasing the risk of splenic clearance of infected cells and hindering parasitaemia increase.

Alternative Nerve Coaptations: End-To-Side and Beyond.

Modern end-to-side (ETS) nerve transfers have undergone several permutations since the early 1990's. Preclinical data have revealed important mechanisms and patterns of donor axon outgrowth into the recipient nerves and target reinnervation. The versatility of ETS nerve transfers can also potentially address several processes that limit functional recovery after nerve injury by babysitting motor end-plates and/or supporting the regenerative environment within the denervated nerve.
