Director: Mohammad Hossein Rahbar,
BERD provides leadership, expertise, and advice in biostatistics, epidemiology, and research design to investigators in the CCTS. BERD’s mission is to promote (within our CCTS-affiliated institutions as well as across CTSAs nationwide) innovative, state-of-the-art clinical and translational research of maximum public health benefit and scientific impact. BERD provides the resources required to pursue the following objectives in support of the overall goals of the CCTS.
To achieve these goals, BERD will seize every opportunity (e.g., through informal consultations as well as classroom instruction) to develop a collaborative relationship with clinical/translational investigators (primarily within our CCTS-affiliated institutions) to promote the rapid development of innovative research ideas and the rapid dissemination of valid research findings. Typically, this is a long-term process that begins with providing assistance with study design and epidemiological and statistical methods in the development of a research proposal, proceeding (most often iteratively) with the acquisition of funding, and, over the course of actually conducting the study, producing findings and publications (most often iteratively). The goals of BERD include collaboration with investigators to optimize the often complex trade-offs between the research innovation, its potential medical/public health impact, and the required investments of time and resources. BERD aims to reduce the number of iterations required to successfully obtain research funding and to publish research findings.
BERD faculty, staff, and trainees also conduct their own clinical and translational research and collaborate with leading statisticians in the Texas Regional CTSA Consortium and the national CTSA program.
Research support through BERD is available in the following capacities: collaboration, consultation, or fee-for service contract. An initial BERD consultation to assess an investigator’s research needs is offered free of charge. For established, funded projects seeking an hourly “fee-for-service” arrangement, a written contract will be provided. Such projects typically require data management and statistical analysis. Whenever possible, we recommend a collaborative arrangement in which a fixed percent effort of a BERD faculty member is budgeted into the funding application. This prospective arrangement has the advantage of assuring the investigator that the necessary resources have been pre-negotiated and will be available when the application is funded.
The Division of Clinical and Translational Sciences (DCTS) within the Department of Internal Medicine of The University of Texas Health Science Center at Houston (UTHealth) Medical School serves as the primary academic home for faculty in BERD. In 2012, Dr. Rahbar, the director of BERD, was appointed as the division head. Please see the division web site for faculty profiles.
Epidemiological Research on Autism Spectrum Disorders (ASD) in Jamaica: Phase 2

Comprehensive Tumor Microenvironment Based Prediction Models in Prostate Cancer
5R01CA140734-04 (PI: Ayala)
National Cancer Institute
Prostate cancer continues to have a significant health care impact due to its high incidence and mortality. Despite advancements in understanding the clinical spectrum of this disease, there are still limits in the ability to identify the patients who present with localized disease but are likely to fail standard treatment and progress to fatal disease. The overall goal of this project is to model a rigorous quantitative and reproducible tumor microenvironment-based test. Based on the hypothesis that such a test will improve predictability of currently used algorithms, the goal is to select those patients who can benefit from combined modality treatments or adjuvant/neoadjuvant approaches, or more intense follow-up.

Epstein-Barr Virus and Multiple Sclerosis: Correlation of Activity National Multiple Sclerosis Society
Multiple sclerosis (MS) is an immune-mediated, demyelinating disease affecting the central nervous system. The etiology of MS is currently not known, but many features of the disease are consistent with an infectious cause. There are several lines of evidence associating MS with Epstein-Barr virus (EBV). Essentially all adults with MS are infected with EBV, EBV infection occurs before the clinical manifestations of MS, and high titers of antibodies against EBV or a history of symptomatic EBV infection predict a higher risk of developing MS. Despite these associations, the relation between the virus and the disease is not clear. The specific aim is to determine whether reactivation of EBV and changes in the anti-EBV immune response correlate with disease activity in relapsing-remitting MS.
Tu Salud, ¡Si Cuenta!: Promotora Training and Community Education for Cancer Prevention Cancer Prevention and Research Institute of Texas (CPRIT)
Tu Salud, ¡Si Cuenta! (Your Health Matters!) community-wide campaign was designed and implemented to reach adults aged 20-64 years and their families along the US/Mexico Border on the topics of physical activity and healthy food choice. It was hypothesized that individuals who reported exposure to multiple components of the CWC would also report greater physical activity and fruit and vegetable consumption. The purpose of this project is to implement community based cancer prevention using technology among the Mexican Americans.

This project is part of the current research program of the Southwest Center for Agricultural Health, Injury Prevention, and Education at the University of Texas Health Science Center at Tyler that sponsors research, education/outreach programs.
Center for Research Translation in Scleroderma
This Center focuses on molecular approaches to understand the pathogenetic mechanisms (including genetic factors) and predictors of outcomes in systemic sclerosis. The study aims to identify the cellular pathways leading to disease and optimal targets for effective therapy and prevention. The patient population includes three major ethnic groups. There are 3 projects: 1. Functional Genomics Approach to Systemic Sclerosis Pathogenesis, 2. Gene Expression as Predictors of Outcomes in the GENISOS (Genetics versus Environment in Scleroderma Outcomes Study) Cohort, and 3. Role of TGF3 and CTGF Signaling in Transgenic Mouse Models of Scleroderma.
Randomized Trial of Comprehensive Lifestyle Modification, Optimal Pharmacological Treatment and PET Imaging for Detection and Management of Stable Coronary Artery Disease (The Century Trial)
The purpose of this randomized, controlled trial is to 1) evaluate the impact of stress perfusion imaging with SPECT or PET on post-test resource utilization and on risk stratification, and 2) assess whether a comprehensive program of lifestyle modification and lipid management, compared with standard therapy, reduces cardiovascular risk in patients with known disease or at high risk for coronary artery disease. Eligible patients are between 40 and 75 years of age and referred by their physicians to receive SPECT imaging. Participants are assigned randomly to receive either a comprehensive intervention program or standard follow-up care by their referring physician and are followed for five years to compare their post-intervention outcome scores on a standardized scale measuring cardiovascular risk factors and survival free of serious adverse cardiovascular disease events (e.g., myocardial infarction, stroke).
