Differential Effects of Processing Time and Duration of Collagenase Digestion on Human and Murine Fat Grafts.

Background: Autologous fat graft retention is unpredictable, and mechanisms of optimization are poorly understood. Attempts at improving retention use collagenase experimentally and clinically to isolate the stromal vascular fraction to "enhance" fat grafts. However, no standardized duration for collagenase digestion or time following fat graft harvest has been established.

Resident Participation in International Surgical Missions is Predictive of Future Volunteerism in Practice.

Background: Interest in global health and international mission trips among medical student and resident trainees is growing rapidly. How these electives and international mission experiences affect future practice is still being elucidated. No study has identified if participation in international surgical missions during residency is a predictor of participation in international surgical missions in practice after training completion.
