Diversity in the Physician Assistant Pipeline: Experiences and Barriers in Admissions and PA School.

INTRODUCTION: The purpose of this study was to identify perceived barriers faced by physician assistant (PA) students who identified as an underrepresented minority in medicine (URM-med), sexual or gender minority (SGM), coming from low socioeconomic status (low SES), or a person with a disability (PWD). METHODS: More than 2700 PA students across the United States provided information regarding their PA school application process and program experiences. This study examined differences among URM-med, SGM, low SES, and PWD compared to those who were not in those groups to determine the relationship between these factors and student concerns about bias in the application process, as well as a variety of experiences in PA school. RESULTS: Using ordinal logistic regression analyses to examine the odds of experiencing a variety of barriers or experiences in applying to PA school and postmatriculation experiences, results suggested that, among disadvantaged groups within the PA student body, barriers include concerns about bias in the application process, lack of belonging, and the lack of academic and social support. DISCUSSION: PA students who identified as URM-med, SGM, low SES, and/or PWD faced barriers as they navigated the path to becoming a PA. To decrease these barriers, emphasis on raising awareness and interest in pursuing a career as a PA should occur early. Programs should work to identify biases within admissions processes, diversify faculty, and identify ways to support minority students once matriculated. Ultimately, increasing the diversity of healthcare providers has the potential to increase access to and quality of care for patients.

Physico-mechanical and biological evaluation of heparin/VEGF-loaded electrospun polycaprolactone/decellularized rat aorta extracellular matrix for small-diameter vascular grafts.

Although the continuous development of small-diameter vascular grafts (SDVGs) (D < 5 mm) continues, most vascular grafts are made from synthetic polymers, which lead to serious complications from arteriosclerosis, thrombosis, and vascular ischemia. Here, to address these shortcomings, we combine synthetic polymers with natural decellularized small-diameter vessels and loaded with growth factor. We fabricated vascular grafts by electrospinning polycaprolactone (PCL) to decellularized rat aorta matrix (ECM) followed by heparin and vascular endothelial growth factor (VEGF) loading. In- vitro studies showed that PCL/ECM/VEGF vascular grafts, showed excellent hemocompatibility and biocompatibility properties. The vascular grafts implanted into the rat aorta revealed that the PCL/ECM/VEGF grafts promotes endothelial cells and smooth-muscle cells infiltration with a rate of FLK-1, ICAM1, and a-SMA distribution higher than that of the PCL and PCL/ECM vascular grafts at 2 weeks and 4 weeks after implantation. The PCL/ECM/VEGF vascular graft should be considered for potential small-diameter vascular grafts in clinical fields.
