Shape Memory Polymer Scaffolds-Utility for In Vitro Osteogenesis of Canine Multipotent Stromal Cells.

A biodegradable, shape memory polymer (SMP) scaffold based on poly(ε-caprolactone) (PCL) represents an attractive alternative therapy for the repair of critically sized bone defects given its ability to press-fit within irregular defects. Clinical translation of SMP scaffolds requires successful movement beyond proof-of-concept rodent studies through a relevant large-animal model and into the clinical setting. In addition to representing a clinical veterinary population, the canine species is a strong translational model for humans due to similarities in orthopedic disorders, biomechanics, and bone healing.

Biocompatibility and Bone Regeneration by Shape Memory Polymer Scaffolds.

Biodegradable, shape memory polymer (SMP) scaffolds based on poly(ε-caprolactone) (PCL) offer unique advantages as a regenerative treatment strategy for critical-sized bone defects. In particular, a conformal fit may be achieved following exposure to warm saline, thereby improving osseointegration and regeneration. Advancing the clinical translation of these SMP scaffolds requires establishment of efficacy not only in non-loading models, but also load-bearing or load-sharing models.

Point-of-Care Ultrasound Track in an Academic Family Medicine Department.

Introduction: Point-of-care ultrasound (POCUS) is increasingly being employed in family medicine. Residency tracks can be an effective way to increase mastery in a specific subdiscipline for interested residents, but no studies exist on the implementation of a POCUS track in family medicine. We address this gap in the literature by assessing POCUS use by POCUS track residents compared to non-POCUS track residents and faculty in an academic family medicine department.
