Research Accolades for Students and Investigators in Center for Cardiovascular and Respiratory Sciences
Four translational science research projects within the Center for Cardiovascular and Respiratory Sciences (CCRS) have been highlighted at national meetings in the coming weeks. These projects, using a team science approach, have been targeted at identifying the mechanistic links and health outcomes of key co-morbidities associated with elevated cardiovascular and metabolic disease risk.
At “Translational Science 2016”, the Annual Meeting for the Association for Clinical and Translational Science (ACTS):
Ms. Kristin Grogg, PhD student, will present a research project titled “Interventions Blunting Vascular Inflammation and Oxidant Stress Reduce Depression in Obesity”. This project utilizes a large database of basic science results with advanced epidemiological and biostatistical analyses to develop a mechanistically-rigorous model for predicting the development and severity of depressive symptoms with the progression of obesity and diabetes.
Dr. Sarah Singh, PhD student, will present her research project titled “Relationship between Abnormal Ankle Brachial Index and Metabolic Syndrome: Estimates from the National Health and Nutrition Examination Survey”. This study represents an epidemiological approach using the NHANES dataset to identify relationships between the severity of peripheral vascular disease risk with alterations to vascular structure and function, as evidenced by the “ankle-brachial index” (ABI). The results have important implications for primary prevention in primary care settings.
The senior investigator on both projects is Dr. Stephanie Frisbee, from the Department of Health Policy, Management and Leadership in the School of Public Health.
The Association for Clinical and Translational Science (ACTS) uniquely provides an outstanding platform for enhancing education, research, and public policy related to clinical and translational science. ACTS members consist of leaders, investigators, and trainees from academic medical centers, government, industry, and philanthropy. Their annual meeting represents the premiere outlet for the dissemination of clinical and translational research in the United States.
At “Experimental Biology 2016”, two presentations (below) have been highlighted by the Federation of American Societies for Experimental Biology (FASEB) for international press release, spotlighting the research accomplishments of the investigators and trainees within the CCRS:
Mr. Kent Lemaster, PhD student, will present his project titled “Reversing the Effects of Chronic Stress on the Aorta with Exercise Training”. This innovative research finds that aerobic exercise kept the vasculature of rats that developed depressive symptoms as a result of chronic stress functioning normally. The potential translational impact of this work was specifically highlighted, noting that exercise may be an important therapy for promoting cardiovascular health in chronically stressed individuals.
Ms. Kristin Grogg will present her project titled “Early Improvements in Blood Lipid Profile and Vascular Alterations after Gastric Bypass Surgery prior to Dramatic Weight Loss”. This research, which was performed using the patient population of Dr. Lawrence Tabone in the Division of Bariatric Surgery, investigated the health benefits of Roux-en Y gastric bypass surgery that are present very soon after the procedure. Ms. Grogg determined that patients who underwent the procedure showed reductions in weight, waist circumference and body-mass index one week after the procedure. Further, these results demonstrated lower low-density lipoprotein levels and showed indications that patients’ blood pressure and cardiac oxygen demand—how hard the heart is working—were decreasing towards normal ranges. These data suggest cardiovascular health can start improving in the very early stages of recovery before dramatic weight loss occurs following bariatric procedures.
The senior investigators on these projects are Drs. Paul Chantler (Division of Exercise Physiology), Jefferson Frisbee (Department of Physiology and Pharmacology) and Lawrence Tabone (Division of Bariatric Surgery).
Cardiovascular Science Investigator Teams Receive National and International Recognition
Innovative interdisciplinary research initiatives in the Center for Cardiovascular and Respiratory Sciences (CCRS) at the WVU Health Sciences Center have continued to garner national and international recognition for the accomplishments of its diverse investigator teams. The diligent work done, and investment made, by these teams – which represent the combined efforts of basic scientists, physician scientists, and population scientists – have allowed for the acquisition of critical insight into the development, outcomes and implications for elevated cardiovascular disease risk in a manner that was not previously possible at the WVU HSC. Highlights of this work that will be presented at multiple national/international meetings in Spring and Summer of 2016 are outlined below.
Society of Toxicology Annual Meeting (New Orleans, LA):
From the laboratory of Dr. Timothy Nurkiewicz (Professor of Physiology and Pharmacology), Mr. Alaeddin Abukabda (Doctoral student in Cellular and Integrative Physiology) will present work demonstrating the negative impact of nano-TiO2 exposure on the ability of blood vessels to response to physiological stimuli, while Mr. Cody Nichols (Doctoral student in Exercise Physiology) will describe how maternal inhalation of engineered nanomaterials during gestation has the ability to alter genetic/genomic signaling in the fetus. Additionally, Dr. Phoebe Stapleton (Assistant Professor of Physiology and Pharmacology) has been invited to present her research on the impact of maternal nano-TiO2 inhalation throughout pregnancy on microvascular function and potential for end-organ damage in offspring.

Translational Research Highlighted as a PodCasts
Working as a collaborative effort between the CCRS and the Center for Basic and Translational Stroke Research, a study by Dr. Paul Chantler (Assistant Professor of Exercise Physiology) received an Editorial Highlight and PodCast from the Editors of the American Journal of Physiology. Dr. Chantler’s work highlighted the important of early, and aggressive, intervention under conditions of metabolic disease to blunt the development of cerebrovascular impairments to potentially lessen the risk for occlusive stroke and the severity of the outcomes following an incident once it has occurred. The full manuscript can be found here (http://ajpheart.physiology.org/content/309/11/H1846.long) and the PodCast can be heard in its entirety at: http://ajpheart.podbean.com/e/metabolic-syndrome-and-cerebral-vascular-function/
A recent team effort in the CCRS investigating the progressive loss of capillaries and microvessels in tissues with the development of metabolic disease was made possible only because of the strong links and efforts between basic science investigators, clinicians and population scientists. This work highlighted advanced biostatistical analyses as a discovery tool for identifying putative mechanisms that link metabolic disease with chronic microvessel death. The full manuscript can be found here http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4269700/ and the PodCast can be heard in its entirety at: http://ajpheart.podbean.com/e/metabolic-syndrome-and-microvessel-density/.
A novel team science effort being led by Drs. Melissa Olfert (Assistant Professor of Nutritional Science) and Mark Olfert which is targeted at improving consumer decision making for dietary choices has demonstrated the significant benefit that nutritional interventions can lead to significant positive outcomes for microbiome, metabolomic and cardiovascular health in young adults in Appalachia. This work has been extremely well received and has been presented at the Mayo Clinic and the Southeast Regional IDeA conference, both of which resulted in awards for Ms. Oluremi Famodu, RD.
