Immune response profiling in patients with traumatic injuries associated with alcohol ingestion.

Dr. Alexander T. Limkakeng, Jr., MD, MHSc, FACEP is a Professor of Emergency Medicine, Vice Chair of Clinical Research, Director of the Acute Care Research Team, and Director of the Resident Research Fellowship for the Department of Emergency Medicine in the Duke University School of Medicine in Durham, North Carolina.

Dr. Limkakeng has served as chair of the American College of Emergency Physicians (ACEP) Research Committee, and been the Course Director of the ACEP Research Forum from 2016-2018, the largest emergency medical research platform in the nation. He is also the Assistant Director of ACEP’s Emergency Medicine Basic Research Skills course. He was elected to the Nominating Committee of the Society of Academic Emergency Medicine.

As a researcher, Dr. Limkakeng has led multiple clinical trials and interdepartmental sponsored projects and is author on over 100 peer-reviewed manuscripts. These include studies in emergency conditions such as COVID-19, traumatic brain injury, hypertension, heart failure, thrombosis, stroke, envenomations, and septic shock. His research has been funded by grants and contracts totaling over $9 million dollars. He has lectured internationally on acute coronary syndrome, responsible conduct of research, design of clinical trials, and precision medicine in emergency care. He has led Duke’s involvement in NIH-funded research networks and in industry-funded work that led to FDA approval for multiple high-sensitivity cardiac troponin assays and point-of-care COVID-19 diagnostic tests. He has servesd as Co-PI for the Duke U24 Hub in the NIH Early Phase Pain Investigation Clinical Network (EPPIC-Net) (1U24NS114416) and now serves as a co-PI on the Duke U24 Hub award (1U24NS129498) in the NIH Strategies to Innovate Emergency Care Clinical Trials (SIREN) Network and in the NIH NINDS Strokenet network (1U24NS135250)

His personal research interest is finding new ways to diagnose acute coronary syndrome. In particular, he is interested in novel biomarkers and precision medicine approaches to this problem. The common element throughout this work is a focus on time-sensitive health conditions.

Catherine Staton MD MSc

Dr. Staton is an Associate Professor in Emergency Medicine (EM), Neurosurgery & Global Health with tenure at Duke University. She is the Director of the GEMINI (Global EM Innovation & Implementation) Research Center and the EM Vice Chair of Research Strategy & Faculty Development. Her research integrates innovative implementation methods into health systems globally to improve access to acute care. In 2012, with an injury registry at Kilimanjaro Christian Medical Center, Tanzania Dr. Staton demonstrated 30% of injury patients had at risk alcohol use, providing preliminary data for a K01/Career Development Award. Her K01 award adapted a brief alcohol intervention to the KCMC ED and Swahili and is now being trialed in an NIAAA funded R01 pragmatic adaptive clinical trial. Dr. Staton and her mentor and collaborator Dr. Mmbaga are co-PD of the “The TReCK Program: Trauma Research Capacity Building in Kilimanjaro” to train 12 masters and doctoral learners to conduct innovative implementation and data science projects to improve care for injury patients. Currently, Dr. Staton and GEMINI partners with over a dozen faculty from over 6 low- and middle-income countries to conduct research, has mentored over 150 learners from undergraduate to post-doctoral levels from high, middle and low- income settings and has over 130 manuscripts.

I am a surgeon with interest in immune management of transplant recipients. I am particularly interested in therapies that influence T cell costimulation pathways and adjuvant therapies that facilitate costimulation blockade to prevent the rejection of transplanted organs without undue suppression of protective immunity. I am also interested in understanding how injury, such as that occurring during trauma or in elective surgery, influences immune responses and subsequent healing following injury.
