Controversy remains about appropriate mesh selection during ventral hernia repair (VHR) in a contaminated field. Fear of mesh infection has led to increased use of biologic and absorbable synthetic meshes rather than permanent synthetic mesh in these cases. We report the safety and efficacy of permanent synthetic mesh during contaminated VHR. ⋯ Permanent synthetic mesh placed in an extraperitoneal position is not only safe for VHR in a contaminated field, but it confers a significantly lower rate of surgical site infection and recurrence compared with biologic or bioabsorbable meshes.

Mitochondrial oxidative stress plays a prominent role in the development of burn-induced cardiac dysfunction. AMP-activated kinase (AMPK), an energy sensor, has a central role in the pathogenesis of heart failure. However, its role in cardiac dysfunction after burn injury is unclear. Our hypothesis is that burn injury acts through the AMPK-sirtuin 1-PGC1α-nuclear factor erythroid 2-related factor 2 (NFE2L2)-ARE signaling pathway, leading to cardiac mitochondrial impairment, resulting in cardiac dysfunction. ⋯ Burn-induced cardiac dysfunction and cardiac mitochondrial damage occur via the AMPK-sirtuin 1-PGC1α-NFE2L2-ARE signaling pathway. AMPK and PGC1α agonists might be promising therapeutic agents to reverse cardiac dysfunction after burn injury.
