Potential Cost Savings Of Not Doing Cd4 Counts In Hiv Positive People In Rhode Island With An Undetectable Viral Load, Ruth Dele-Oni, Ferdinand Schumacher, Zachary Markus, Timothy Flanigan, Md

Journal of Health Disparities Research and Practice

CD4 cells fight infections in the body. When someone contacts Human Immunodeficiency Virus (HIV), their CD4 cells are taken over by HIV which turns them into manufacturers of many copies of the virus. The Viral Load (VL) measures the amount of virus in the blood. When HIV takes over the CD4 cells, the VL increases while the number of necessary CD4 cells decreases. When patients maintain stable treatment, their CD4 counts rise, and VLs may become undetectable, indicating the virus is too little to be detected in their blood. Knowing this, is frequent CD4 counts necessary for those with undetectable …

Defining The Role For Zbp-89 In Atm-Mediated Dna Damage Response To Irradiation In The Intestine, Christine Carethers, Juanita L. Merchant, Md, Phd

Journal of Health Disparities Research and Practice

ZBP-89 (ZNF148, Zfp148) is a zinc-finger transcription factor that inhibits cellular proliferation when overexpressed in cell lines. ZBP-89 forms a protein-protein interaction with p53 and Ataxia-telangiectasia mutated (ATM). However, it is unclear how the interaction modulates the function of these two proteins in vivo.

Double strand DNA breakage induced by -irradiation induces ATM phosphoinositol kinase activity, which initiates a cascade of events culminating in cell cycle arrest, DNA repair or apoptosis. Elevated levels of ZBP-89 induce growth arrest and apoptosis in gastrointestinal cell lines. Therefore, we hypothesize that ZBP-89 facilitates cell growth arrest and activation of the DNA repair pathway …

Induction Of Dusp9 In Xenografts From Human Breast Cancer Cell Lines Increases Mammary Cancer Stem Cells, Albert Barrios, Meher Parveen, Phd, Easter Thames, Melanie Baker, Shelha Pervin, Phd

Journal of Health Disparities Research and Practice

Breast cancer remains a complex disease that kills 40,000 women every year. Initiation and progression of breast cancer is influenced by heterogeneous groups of cells, including mammary cancer stem cells (MCSCs). Progression of this dreadful disease is driven by many signaling pathways among which MAPK pathway is highly prominent. Since targeting prominent kinases in MAPK pathway has been unsuccessful to control breast cancer, it is important to examine the phosphatases that regulate the activity of these kinases.

Using xenograft model from breast cancer cell lines, our lab has found that during the initial stages of xenograft development (week 1-4, 100-200mg …

Characterization Of Left-Ventricular Thrombus Formation Using High Frequency Ultrasound, Kelsey A. Bullens, Arvin H. Soepriatna, Pavlos P. Vlachos, Craig J. Goergen

The Summer Undergraduate Research Fellowship (SURF) Symposium

Heart failure is a leading cause of death in the United States, and cardiac thrombus, a common morbidity associated with heart failure, significantly increases a patient’s risk of embolic events. The objective of this project is to characterize left-ventricular (LV) thrombus development using high frequency ultrasound imaging in a murine model. C57BL/6J wild-type mice (n=6) were injected intraperitoneally with iron dextran five times a week for six weeks to increase oxidative stress in the heart. Granulocyte-colony stimulating factor (G-CSF) was subcutaneously injected daily during the second week to initiate stem cell migration and stimulate endothelial cell activation, thus increasing the …

Blood-Tissue Barriers And Autoantibodies In Neurodegenerative Disease Pathogenesis: An Approach To Diagnostics And Disease Mechanism, Eric Luria Goldwaser

Graduate School of Biomedical Sciences Theses and Dissertations

Brain homeostasis can be affected in a number of ways that lead to gross anatomical, cellular, and molecular disturbances giving rise to diseases like Alzheimer’s disease (AD) and related dementias. Unfortunately, the mechanistic pathoetiology of AD’s hallmark features of cerebral amyloid plaque buildup and neuronal death are still disputed. Using human brain AD sections, immunohistochemistry experiments revealed internalized surface proteins, co-localized to an expanded lysosomal compartment. Other stains for amyloid-β1-42 (Aβ42) and various immunoglobulin (Ig) species displayed them leaking out of the cerebrovasculature through a dysfunctional blood-brain barrier (BBB), binding to neurons in the vicinity, and localizing to intracellular vesicles …

Clinical Significance Of Homologous Recombination Deficiency Score Testing In Endometrial Cancer, Jean M. Hansen

Dissertations and Theses (Open Access)

Objectives: Homologous recombination deficiency (HRD) score is related to chemotherapy response in breast and ovarian cancers. The role of HRD is unknown in endometrial cancer. We examined the relationship between HRD score and survival in a cohort of endometrial cancer patients and with tumor growth using murine orthotopic models.

Methods: TCGA was queried to determine frequency and clinical significance of alterations in the HR pathway in endometrial cancer. 137 formalin-fixed paraffin-embedded endometrioid adenocarcinoma patient samples were tested for HRD score, microsatellite instability (MSI) and high mutation load (HML) using a next generation sequencing assay targeting the coding regions of 43 …

Racial And Ethnic Disparities In Dermatology Office Visits Among Insured Patients, 2005-2010, Valerie M. Harvey, Joan Paul, L. Ebony Boulware,

Journal of Health Disparities Research and Practice

Objective:To determine whether differences in race and ethnicity affect the usage of dermatological services.

Methods: Data from the National Ambulatory Medical Care Survey were used to study trends in ethnic/race rates of outpatient dermatology office visits among publicly and privately insured patients from 2005-2010. In multivariable models, we explored the magnitude of ethnic/race differences in dermatology visit attendance for patients with public vs. private insurance.

Results: From 2005-2010, dermatology visit utilization increased among insured Hispanics, but not among insured non-Hispanic Blacks or whites. Visits were less frequent by those with public insurance compared to private insurance. Privately and publicly …

Hispanic Representation In A Longitudinal Birth Cohort Study, Julie Postma, Lisa R. Younglove, Kerry Brooks, Tamara Odom-Maryon, Shirley Beresford, Thomas Burbacher, Phillip Butterfield, Patricia Butterfield, Nicole Cederblom, Kimberly Grant, Elaine M. Faustman

Journal of Health Disparities Research and Practice

Background: The purpose of this paper is to report: 1) strategies used to engage Hispanic women and their families in a longitudinal birth cohort study, and 2) comparisons of Hispanic and non-Hispanic groups that received those strategies. This paper augments the current literature by reporting methods and results specific to a subpopulation of Hispanic women, that of self-identified Mexican women. Comparisons between Hispanic and non-Hispanic groups that received those strategies will build the evidence base that supports effective outreach and engagement strategies.

Methods: Cultural responsiveness theory was used to structure outreach and engagement, including: 1) assembling a culturally competent team; …

Guidelines Are Not Evidence, James P. Meza Md, Phd, Nicholus H. Yee Md

Clinical Research in Practice: The Journal of Team Hippocrates

Guidelines are inherently flawed when caring for an individual patient, because they apply to populations, not individuals. A strong competency in reading and interpreting clinical research gives doctors the power to evaluate guidelines and make appropriate shared decisions with their patients.
