    A Framework for Developing Antiracist Medical Educators and Practitioner–Scholars
    (Wolters Kluwer, 2021-08-31) Sotto-Santiago, Sylk; Poll-Hunter, Norma; Trice, Traci; Buenconsejo-Lum, Lee; Golden, Sherita; Howell, Joy; Jacobs, Nicole; Lee, Winona; Mason, Hyacinth; Ogunyemi, Dotun; Crespo, Waleska; Lamba, Sangeeta; Medicine, School of Medicine
    With an increasing awareness of the disparate impact of COVID-19 on historically marginalized populations and acts of violence on Black communities in 2020, academic health centers across the United States have been prioritizing antiracism strategies. Often, medical students and residents have been educated in the concepts of equity and antiracism and are ready to tackle these issues in practice. However, faculty are not prepared to respond to or integrate antiracism topics into the curriculum. Leaders in faculty affairs, education, diversity, and other departments are seeking tools, frameworks, expertise, and programs that are best suited to meet this imminent faculty development need. In response to these demands for guidance, the authors came together to explore best practices, common competencies, and frameworks related to antiracism education. The focus of their work was preparing faculty to foster antiracist learning environments at traditionally predominantly-White medical schools. In this Scholarly Perspective, the authors describe their collaborative work to define racism and antiracism education; propose a framework for antiracism education for faculty development; and outline key elements to successfully build faculty capacity in providing antiracism education. The proposed framework highlights the interplay between individual learning and growth and the systemic and institutional changes needed to advance antiracist policies and practices. The key elements of the framework include building foundational awareness, expanding foundational knowledge on antiracism, embedding antiracism education into practice, and dismantling oppressive structures and measuring progress. The authors list considerations for program planning and provide examples of current work from their institutions. The proposed strategies aim to support all faculty and enable them to learn, work, and educate others in an antiracist learning environment.

    Vascular Patterning as Integrative Readout of Complex Molecular and Physiological Signaling by VESsel GENeration Analysis
    (Karger, 2021) Lagatuz, Mark; Vyas, Ruchi J.; Predovic, Marina; Lim, Shiyin; Jacobs, Nicole; Martinho, Miguel; Valizadegan, Hamed; Kao, David; Oza, Nikunj; Theriot, Corey A.; Zanello, Susana B.; Taibbi, Giovanni; Vizzeri, Gianmarco; Dupont, Mariana; Grant, Maria B.; Lindner, Daniel J.; Reinecker, Hans-Christian; Pinhas, Alexander; Chui, Toco Y.; Rosen, Richard B.; Moldovan, Nicanor; Vickerman, Mary B.; Radhakrishnan, Krishnan; Parsons-Wingerter, Patricia; Ophthalmology, School of Medicine
    The molecular signaling cascades that regulate angiogenesis and microvascular remodeling are fundamental to normal development, healthy physiology, and pathologies such as inflammation and cancer. Yet quantifying such complex, fractally branching vascular patterns remains difficult. We review application of NASA’s globally available, freely downloadable VESsel GENeration (VESGEN) Analysis software to numerous examples of 2D vascular trees, networks, and tree-network composites. Upon input of a binary vascular image, automated output includes informative vascular maps and quantification of parameters such as tortuosity, fractal dimension, vessel diameter, area, length, number, and branch point. Previous research has demonstrated that cytokines and therapeutics such as vascular endothelial growth factor, basic fibroblast growth factor (fibroblast growth factor-2), transforming growth factor-beta-1, and steroid triamcinolone acetonide specify unique “fingerprint” or “biomarker” vascular patterns that integrate dominant signaling with physiological response. In vivo experimental examples described here include vascular response to keratinocyte growth factor, a novel vessel tortuosity factor; angiogenic inhibition in humanized tumor xenografts by the anti-angiogenesis drug leronlimab; intestinal vascular inflammation with probiotic protection by Saccharomyces boulardii, and a workflow programming of vascular architecture for 3D bioprinting of regenerative tissues from 2D images. Microvascular remodeling in the human retina is described for astronaut risks in microgravity, vessel tortuosity in diabetic retinopathy, and venous occlusive disease.
