Impact of perioperative hyperglycemia in patients undergoing microvascular reconstruction.

Background: The effects of perioperative hyperglycemia on complications and outcomes in microvascular reconstruction have not been reported in the literature.

Methods: A retrospective cohort of 203 patients undergoing microvascular reconstruction was generated. Perioperative glucose levels and clinical factors were tested for associations with complications using simple and multivariate analyses.

Assessment of the biocompatibility and stability of a gold nanoparticle collagen bioscaffold.

Collagen has been utilized as a scaffold for tissue engineering applications due to its many advantageous properties. However, collagen in its purified state is mechanically weak and prone to rapid degradation. To mitigate these effects, collagen can be crosslinked.
