The specific clinical and arrhythmia characteristics of ERAT influencing late recurrence risk in persistent AF are unclear. In addition, the impact of different ablation strategies on the incidence and prognostic significance of ERAT remains unknown.

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).

Background: Periprosthetic infection after breast reconstruction is not uncommon and can result in loss of the implant pocket and negative patient outcomes. Management of these infections typically involves removal of the prosthesis, treatment with antibiotics, and delayed reconstruction upon infection resolution. The impact of adjunctive use of negative pressure wound therapy with instillation and dwell (NPWTi-d) on breast pocket salvage rates, time to implant reinsertion, and related outcomes was examined.
