    Interests/Achievements:

    In this country we have a hard time making decisions on our healthcare directives. We need to make people aware that it is "ok" to discuss end-of-life decisions along with our healthcare needs in an emergency. Discussing and appointing an advocate can bring a person's treatment in line with their wishes. We need to make the public aware of what an advanced directive can do for them and make it so people are not afraid to discuss these issues. Audrey helped build a program to identify the disparity between the way people die and the way they state they want to die, recognizing the lack of patient family perspective in decision-making. Barriers were identified along with ethical considerations and principles.

  • Toddra S. Liddell, M.S.N.

    Toddra S. Liddell, M.S.N.

    Assistant in Medicine
    Division of:
    Nephrology and Hypertension
    Previous Institution:
    Kroger Little Clinic/Hunter Lane Medical
    Previous Role/Title:
    Nurse Practitioner
    Specialty:
    Nephrology
    Education/Training:
    M.S.N. - Middle Tennessee State University
    B.S.N., University of Phoenix, Grand Rapids, Michigan
    Hometown:
    Murfreesboro, TN
    Interests/Achievements:

    Toddra’s research interest involves working with primary care providers in early recognition and evaluation of chronic kidney disease (CKD). CKD is associated with substantial morbidity and mortality and affects more than 20 million adults in the United States (Shahinian, Hedgeman, Gillespie, et al., 2013). In its early stages, CKD is manageable by primary care providers. However, care of CKD patient can be very complex, which can pose potential problems with novice providers. Primary providers (novice/experienced MD, NP, PA) must properly manage CKD patients, which includes blood pressure control, lipid control, and glycemic control. A study that analyzed renal endpoints of the Multifactorial Approach and Superior Treatment Efficiency in Renal Patients with the Aid of Nurse Practitioners (MASTERPLAN) showed that additional support by nurse practitioners attenuated the decline of kidney function and improved renal outcome in patients with CKD (Peeters, van Zuilen, Wetzels, et al., 2014). Toddra would therefore like to further build upon this to determine the outcomes of CKD by nurse practitioner providers. She is also interested in depression in minority populations. Minority populations are at greater risk for developing depression mainly due to lack of medical access, the stigma associated with depression, and inadequate medical management of depression. African Americans are less likely to receive accurate diagnosis. There is a prevalence of under-recognition in Hispanics, as well. However, there are many barriers that can influence under-recognition including language differences, health literacy, and others. Toddra would like to develop this research by collaborating with local faith-based groups and community organizations to help identify ways to improve depression in minority populations.

    Education/Training:
    M.D. - University of Maryland
    Hometown:
    Baltimore, MD
    Interests/Achievements:

    Dr. Michaud began his academic career at the University of Michigan by investigating pacing maneuvers that allow easy diagnosis of arrhythmias in the setting of catheter ablation for supraventricular tachycardia. He has since broadened this approach to assist ablation operators in more complex arrhythmia cases and is credited with at least four separate pacing maneuvers that are now part of core testing during specialty board examinations for cardiac electrophysiology. As Director of the Center for the Advanced Management of Atrial Fibrillation at Brigham and Women's Hospital, Dr. Michaud played a pivotal role in developing better ablation strategies for the treatment of atrial fibrillation, which is the most common arrhythmia requiring hospitalization. These methods involve assessing and improving the quality of radiofrequency ablation lesions, the result of which improves procedure success by making pulmonary vein isolation more durable. He is currently working on strategies to optimize lesion delivery by varying the amount of coolant delivered through the tip of the ablation catheter. Dr. Michaud has spoken at national and international academic conferences on his work in arrhythmia diagnosis and treatment and has authored or co-authored numerous manuscripts. He is currently Co-Director of the Heart Rhythm Society board review course for cardiac electrophysiology. As Chief of the Section of Cardiac Electrophysiology, Dr. Michaud hopes to create a clinical and research center focused on a comprehensive approach to understanding and managing complex arrhythmias.

    Specialty:
    Hometown:
    Interests/Achievements:

    Dr. Zhu’s research interest is to understand the relationship between energy homeostasis and inflammation, which might be a foundational mechanism for insulin resistance, hyperlipidemia, and atherosclerosis. Her research focuses on the use of mouse disease models to identify mechanisms that underlie insulin resistance and atherosclerosis. She aims to define fundamental principles of how to improve HDL function for patients with type-2 diabetes to reduce cardiovascular disease. During Dr. Zhu’s graduate studies, she studied the regulation of PCYT2, a rate-limiting enzyme for phospholipid synthesis, at transcriptional and posttranscriptional levels. This work resulted in seven publications with four of them as the first author. During her training as a postdoctoral fellow in the Division of Cardiovascular Medicine at Vanderbilt, Dr. Zhu demonstrated that LRP1-deficient macrophages caused inflammatory responses in the artery walls due to the impaired ability of foam cells to clear the plaque. In another high-impact project, she found that anti-inflammatory macrophages promoted cholesterol reverse transport and macrophage migration out of artery walls, leading to atherosclerosis regression. This novel discovery may set up a platform to develop therapeutic policies to prevent cardiovascular events. During her training in the Division of Diabetes, Endocrinology, and Metabolism at Vanderbilt, Dr. Zhu showed that deletion of liver estrogen receptor alpha led to lipid accumulation in the liver and caused whole body insulin resistance. One of her ongoing projects shows that a clinically used CETP inhibitor increases HDL cholesterol; however, it also increases inflammatory responses and causes insulin resistance in obese mice. This study may explain the reason why clinical trials using CETP inhibitors have failed to prevent cardiovascular disease.

Since 2009, Dr. Zhu has worked at VUMC, and her current research focus is to identify and investigate nutrient-nutrient (e.g., magnesium, calcium) and gene-nutrition interactions in the etiology of colorectal cancer and to subsequently develop personalized prevention strategies. In a two-phase R01 study, Dr. Zhu identified and replicated several gene-nutrient interactions in relation to risk of both colorectal adenoma and hyperplastic polyps. These findings lay a foundation for the development of new precision prevention strategies for colorectal cancer among high-risk populations. In the Personalized Prevention of Colorectal Cancer Trial (R01 CA149633, PI: Qi Dai), Dr. Zhu plays a critical role including coordination, data management, data analysis, data reporting, and manuscript development. She has also obtained research funding as a PI.
