Abstract
A wide variety of diseases are commonly diagnosed via the visual examination of cell morphology within a peripheral blood smear. For certain diseases, such as COVID-19, morphological impact across the multitude of blood cell types is still poorly understood. In this paper, we present a multiple instance learning-based approach to aggregate high-resolution morphological information across many blood cells and cell types to automatically diagnose disease at a per-patient level. We integrated image and diagnostic information from across 236 patients to demonstrate not only that there is a significant link between blood and a patient's COVID-19 infection status, but also that novel machine learning approaches offer a powerful and scalable means to analyze peripheral blood smears. Our results both backup and enhance hematological findings relating blood cell morphology to COVID-19, and offer a high diagnostic efficacy; with a 79% accuracy and a ROC-AUC of 0.90.

As a diagnostic hematopathologist and molecular genetic pathologist, my clinical interests are focused on the histologic examination of tissue and bone marrow biopsies to diagnose hematologic malignancies (leukemia, lymphoma, myeloma, etc.) as well as testing DNA from tumors or from blood to detect inherited or acquired mutations that can guide therapeutic management and predict clinical outcome. My research interests involve 1) understanding the biology of T-cell and NK-cell neoplasms; 2) defining the immunomodulatory response to neoplastic disease; 3) developing methods to monitor immune response and thereby refine tumor immunotherapy; and 4) exploring novel applications of tumor genetics in the diagnosis, prognosis, and management of cancer.

Cardiothoracic Pathologist and Physician-Scientist
Division Chief, Cardiovascular Pathology
Co-Director, Division of Artificial Intelligence and Computational Pathology
Associate Director, Residency Program
Director, Duke University Hospital Autopsy Service
Dr. Glass completed medical residency in Anatomic Pathology at the Brigham and Women’s Hospital/Harvard Medical School followed by fellowships in Cardiothoracic Pathology also at Brigham and Women’s Hospital/Harvard Medical School and Pulmonary/Cardiac Transplant Pathology at the University of Texas Southwestern Medical Center. Dr. Glass initially trained as a vascular surgeon with a focus on endovascular/interventional procedures through the 0+5 Integrated Vascular Surgery Program at the University of Rochester Medical Center from 2007-2011. As a recipient of the NIH National Lung Blood Institute T32 Ruth Kirschstein National Service Research Award, she completed a Ph.D with a concentration in Genomics and Epigenetics in 2014. Dr. Glass serves as P.I. of multiple NIH grants, including U54 and SBIR.
As a thoracic surgical pathologist, Dr. Glass diagnoses complex heart transplant rejection and thoracic malignancies. She works closely with the Duke Thoracic Oncology Group, DCI Center for Cancer Immunotherapy, Duke Division of Cardiovascular Medicine and Cardiothoracic Surgery and Pratt School of Biomedical Engineering.
Dr. Glass is the recipient of the Society of Cardiovascular Pathology (SCVP) Young Investigator’s Award, the William von Liebig Vascular Biology Research Fellowship at the Harvard Institutes of Medicine, the Duke Pathology Salvatore V. Pizzo Faculty Research Mentor Award, the Duke Department of Pathology Early Career Research Achievement Award and is author of over 85 publications (including book chapters in the recent W.H.O. Classification Tumours of the Lung, Pleura, Thymus and Heart) and 50 national presentations in cardiovascular disease, thoracic malignancies, surgery and machine learning.
In addition to her clinical and research activities, Dr. Glass serves on the Executive/National Committees for the Society of Cardiovascular Pathology, College of American Pathology Artificial Intelligence Committee and the Duke School of Medicine Executive Admissions Committee.
Xiaoyin Jiang
I am a pathologist specializing in cytopathology and surgical pathology. I diagnose diseases through integrating clinical history and studying patient samples under the microscope. As a cytopathologist, I perform fine needle aspiration biopsies in our clinic. I serve as Chief of the Head and Neck Service, and Director of the Duke Pathology Communications Group.
My research interests focus on the pathology of the head and neck and endocrine systems, with particular interest in thyroid nodules and neoplasia, and ultrasound-guided FNA. I work with a multidisciplinary team to improve our understanding of disease. I also focus on novel applications of social media for physicians and medical education.
