Hybrid modeling techniques for 3D printed deep inferior epigastric perforator flap models.

Background: Deep Inferior Epigastric Perforator Flap (DIEP) surgical procedures have benefited in recent years from the introduction of 3D printed models, yet new technologies are expanding design opportunities which promise to improve patient specific care. Numerous studies, utilizing 3D printed models for DIEP, have shown a reduction of surgical time and complications when used in addition to the review of standard CT imaging. A DIEP free flap procedure requires locating the inferior epigastric perforator vessels traversing and perforating the rectus abdominis muscle, perfusing the abdominal skin and fatty tissue.

Contingency planning for health care worker masks in case of medical supply chain failure: Lessons learned in novel mask manufacturing from COVID-19 pandemic.

Introduction: The COVID-19 pandemic placed unprecedented strain on the medical supply chain. Early in the pandemic, uncertainty regarding personal protective equipment (PPE) was high. Protecting health care workers from contracting illness is critical to preserve trust and workforce capacity.
