Caitlin W. Hicks, MD, Johns Hopkins University School of Medicine
Research Conducted: Dr. Caitlin Hicks's research interest includes the epidemiology of lower extremity disease and value-based care in vascular surgery. The overarching goal of her work is to better define patients who will benefit from vascular interventions, and to optimize patient care and improve overall patient outcomes. She has raised awareness in the vascular surgery community about possible overuse of different vascular interventions for peripheral artery disease that are associated with high costs but may not improve patient outcomes. She has also worked closely with the leadership of the American Vein and Lymphatic Society to develop a metric of high-value care related to endovenous ablation therapy. By using a peer-benchmarked approach to report individual physician performance, the intervention she led with AVLS results in an immediate and statistically significant drop in outlier performance, resulting in an estimated $11.4 estimated cost savings to Medicare. |

Sam Wang, MD, FACS, University of Texas—Southwestern
Research Conducted: Dr. Wang is studying the molecular mechanisms that cause cancer health outcome disparities in Hispanic gastric cancer patients, who have twice the incidence and mortality as compared to White patients and present younger and with more advanced disease. His clinical interests are in foregut malignancies, including pancreatic, liver, and gastric cancer. In the lab, Dr. Wang is working to understand the molecular mechanisms behind the initiation and progression of these diseases in order to identify novel diagnostic and therapeutic interventions. Upon joining UT Southwestern in 2014, Dr. Wang worked to elucidate the functional role of a chromatin remodeler molecule called ARID-1A, which is one of the most commonly mutated genes in cancer. He found that contrary to conventional wisdom that ARID-1A is simply a tumor suppressor gene, the molecule can have oncogenic effect in liver cancer. In the pancreas, he found that ARID-1A mutations leads to pancreatic ductal adenocarcinoma if mutated in acinar cells and intraductal papillary mucinous neoplasms (IPMN) if mutated in duct cells. |

Hari Nathan, MD, PhD, University of Michigan
Research Conducted: Overarching research goals are to better understand variation in the quality and cost of care for surgical patients and to identify strategies for improving both the quality and cost of care. He has studied surgical care in the Medicare program and has made important contributions to our understanding of how pre-operative patient risk and hospital factors impact the occurrence of complications and cost of care. In particular, his work had been instrumental in demonstrating that peri-operative complications are a chief driver of surgical expenditures, and that patients with multiple medical comorbidities incur outsized costs when they experience complications, even at high volume hospitals. |

Matthew D. Neal, MD, FACS, University of Pittsburgh
Research Conducted: Dr. Neal’s basic science research focuses on the mechanisms of organ failure and coagulopathy following trauma and hemorrhage. Specifically, his lab is interested in the role of innate immune activation in the regulation of hemostasis and thrombosis, and the lab recently discovered a novel signaling pathway in platelets involving the danger signaling molecule, HMGB1. This work, published in the Journal of Clinical Investigation, has led to a series of novel observations regarding platelet response following sterile injury and the role of platelets in thrombotic complications such as DVT and PE. Dr. Neal also runs a clinical research group that is investigating novel resuscitation and hemorrhage control strategies for trauma patients as well as outcomes following massive transfusion and the management of anticoagulation in trauma patients. |

Ankit Bharat, MD, FACS, Northwestern University
Research Conducted: Investigating the pathogenesis and importance of lung-restricted autoimmunity in allograft rejection. Dr. Bharat has described a novel two-hit mechanism for the development of autoimmunity, showing that it plays a dominant role in lung allograft rejection. Upon completion, this work will challenge the current paradigm that only looks at histocompatibility antigens in allotransplantation. Related to his work in immunology, Dr. Bharat has identified the presence of a novel subset of intravascular pulmonary monocytes that are responsible for the initial signals of neutrophil recruitment in the transplanted lung, leading to its injury. |

Benjamin Levi, MD, PhD, University of Michigan
Research Conducted: Developing novel imaging and treatment modalities for trauma induced bone pathologies including heterotopic ossification and non-healing osseous wounds. Dr. Levi’s work has demonstrated that Raman Spectroscopy and near infra-red imaging can detect pathologic extra-skeletal bone formation prior to radiographic detection. This early detection is crucial for the testing of therapeutics that can prevent this destructive process before it begins. Dr. Levi next identified the central signaling pathways that cause heterotopic ossification and has validated several prophylactic strategies in pre-clinical trials. Additionally, he has identified and characterized the “stem cells” that are enriched and are responsible for trauma induced heterotopic ossification. This work has provided the rationale for therapeutic interventions based on bone morphogenetic protein and hypoxia inducible factor one alpha. |

Adil H. Haider, MD, MPH, FACS, Harvard Medical School/Brigham and Women’s Hospital
Research Conducted: Understanding mechanisms that lead to disparities in outcomes after surgery and trauma. In the past, racial disparities research has not been thought to be significant, especially in the field of trauma, where many people still believed that Emergency Rooms are the great equalizers of care and questioned the very existence of any disparities in outcomes.
Current Research: Dr. Haider has moved on from simply describing disparities to actually understanding why they occur and offering solutions with intervention trials. In addition, he and his team are now investigating disparities among LGBT populations and other previously marginalized groups such as those with Dwarfism and American Indians. |

Tippi C. MacKenzie, MD, FACS, UCSF Medical Center
Research Conducted: Fetal surgery is life saving for many patients with congenital anomalies, but it remains limited by high incidence of preterm labor. The study of immune response to fetal surgery can help understand the triggers for preterm labor. During the time of the award, Dr. MacKenzie examined the mother’s immune response and found that T-cell activation in the mother triggers preterm delivery.
Current Research: Dr. MacKenzie’s work now explores the maternal and fetal immune responses to the stress of feral surgery and is making the surprising finding that surgery alters the delicate balance of maternal-fetal tolerance. |
