Rebecca Andrews-Dickert, MDDr. Rebecca Andrews-Dickert’s research has focused on quality of care and clinical decision-making in the assessment and treatment of patients in the emergency care setting. Her research experience includes the assessment and validation of an instrument to measure quality of care provided to children in the Emergency Department. This instrument was then used to evaluate the association of various patient-level, provider-level, and hospital-level factors with process measures of quality of care delivered to pediatric patients in Emergency Departments. An additional area of her research has been the evaluation of an inflammatory biomarker panel consisting of white blood cell (WBC), C-reactive protein (CRP), and myeloid-related protein (MRP) 8/14, and its clinical application to the diagnosis of appendicitis in pediatric patients, with a focus on diagnostic resource utilization and the potential to reduce computerized tomography (CT) ionizing radiation exposure for pediatric patients. Dr. Andrews-Dickert desires to improve patient quality of care through continued research in medical education and clinical decision-making processes, and her areas of research interest at Sam Houston State University College of Osteopathic Medicine include medical education methods, physician decision-making processes, and health care worker career longevity.

Marcos Garza-Madrid, MD PhDDr Garza’s biomedical research interests lie on the interactions between cells and their surrounding environment. Particularly on how to make use of the cellular microenvironment (the extracellular matrix) to affect cells behavior for tissue engineering and biotechnology applications. His early research in hematology and preservation of hematopoietic stem cells paved the way for his interest in environmental control of cellular differentiation. During his doctoral studies Dr. Garza focused on cell sorting and surface modifications for recombinant protein production. His translational post-doctorate research aimed at modifying collagen matrices for ophthalmological applications such as patches and replacement treatment. Dr. Garza is currently establishing research lines in production of self-assembled matrices for cell culture, surface modification for cellular guidance, and tissue engineering. On the medical education front, Dr. Garza is interested in bridging the gaps between curricular design, assessment, and academic success.

Petra Rocic, PhD
https://orcid.org/0000-0002-5781-3075
Dr. Rocic’s research focus is in the area of cardiovascular complications of obesity, type II diabetes and metabolic syndrome. She is particularly interested in myocardial adaptations to transient, repetitive ischemia characteristic of stable angina pectoris, acute ischemia with reperfusion injury that occurs with myocardial infarction, and chronic ischemia associated with heart failure, and how adaptive processes to these conditions are further impaired in patients with the aforementioned risk factors resulting in earlier and greater morbidity and mortality. Currently Dr. Rocic’s lab is working on 20-HETE, a pro-inflammatory cytochrome P450 (CYP) product of arachidonic acid metabolism, which may represent a promising target for pharmacological therapy aimed at reducing infarct size and incidence of heart failure after myocardial infarction in metabolic syndrome patients. In addition, the lab is exploring whether there is a link between elevated plasma 20-HETE levels and the severity of Covid-19, development of the post-Covid-19 syndrome or the robustness of the host antibody-mediated immune response against SARS-Cov2.

Project 1: Plasma Levels of 20-HETE in Patients Diagnosed with COVID-19.
A proinflammatory eicosanoid, 20-hydroxy-5,8,11,14-eicosatetraenoic acid (20-HETE) has recently emerged as a potential biomarker, with high plasma levels positively correlating with poor outcomes in patients with coronary events. Whether predictive value of 20-HETE extends to patients with other inflammatory conditions is unknown. The aims of this project are to determine whether 20-HETE levels are elevated during active SARS-CoV-2 infection and whether elevated levels positively correlate with development pf severe Covid-19 disease and/or post-Covid-19 syndrome and/or inability to develop long-term immunity (low anti-SARS-Cov-2 IgG levels).
Sahar Soliman Rph, PhD https://orcid.org/0000-0002-0648-0979
Dr. Soliman’s translational research training focused on angiogenesis and the neurovascular unit, with an emphasis on repurposing FDA-approved drugs in stroke therapeutics. During her postdoctoral training, she studied the pathogenesis of intraventricular hemorrhage as a complication of prematurity. Her pharmacy training and her passion to promote safe medication practices in rural and underserved areas led her to conduct rural health-centered research studying the opioid crisis in East Texas. Dr. Soliman is conducting her research with a multidisciplinary team from the College of Osteopathic Medicine and Sam Houston State University. Future research in this field includes studying the effect of COVID-19 pandemic on the existing opioid epidemic in East Texas.

Project 1: Trends in Opioid Prescribing in East Texas.
Opioid epidemic is a major public health problem in the United States. The widespread misuse of prescription opioids has been a major contributor to the opioid crisis. The aim of this project is to analyze opioid prescribing rates and trends in our service area, East Texas, in order to more effectively address the opioid crisis.
Project 2: Impact of Health Determinants on the Opioid in East Texas.
This rural-health centered research aims at analyzing the impact of health determinants on the opioid crisis in East Texas. Completion of this project will help identify patients at highest risk of developing opioid use disorder (OUD).
Project 3: Investigating the Effect of COVID-19 Pandemic on Opioid Epidemic in Rural East Texas.
The emergence of COVID-19 epidemic and the emotional toll, imposed by social isolation, unemployment and anxiety, is likely to worsen opioid crisis in rural communities of East Texas, aggravated by the limited access to healthcare. This project aims at analyzing opioid prescribing and dispensing patterns during the COVID-19 outbreak, with the overarching goal of enhancing rural health and reducing rural health disparities.
