Journal of Health Disparities Research and Practice

The purpose of this qualitative study was to conduct a formative evaluation of messages and materials to inform the development of a promotional, health campaign designed to increase breast cancer screening awareness and utilization among low-income, uninsured African American women through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) in Savannah and Macon, Georgia (GA). A priority of CDC is to understand why women eligible for screening through the NBCCEDP do not participate in NBCCEDP screening services as well as to identify effective strategies for increasing enrollment among NBCCEDP-eligible women who have never received breast cancer screening. As …

Microrna Mir-155 Affects Antiviral Effector And Effector Memory Cd8 T Cell Differentiation, Ching-Yi Tsai, S. Rameeza Allie, Weijun Zhang, Edward J. Usherwood

Dartmouth Scholarship

MicroRNAs are key regulators of the immune response, but their role in CD8 T cell differentiation in vivo is not known. We show that miR-155 is important in both effector and memory antiviral CD8 T cell responses. Without miR-155, there was a weaker effector response and a skewing toward memory precursor cells. At the memory stage, miR-155-deficient CD8 T cells preferentially differentiated into central memory cells and were capable of mounting a potent secondary response.

The Effectiveness Of Health Education Materials In Influencing Hiv Testing Behavior: The Unlv-Siphi Study, Rebecca Tsegay

UNLV Theses, Dissertations, Professional Papers, and Capstones

The UNLV-SIPHI (Sexual Health Internet-Based Public Health Intervention) Study focused on HIV prevention by improving HIV testing behavior through the development and dissemination of health education materials. The goal of the UNLV-SIPHI Study was to develop effective, custom-made HIV health education materials that promote the knowledge, intention and practice of HIV testing among UNLV students. The UNLV-SIPHI Study was conducted during Spring 2012 semester in selected UNLV undergraduate classes. An online quasi-randomized-control trial (RCT) was used to measure the difference in HIV testing behavior contributing factors among students exposed to the health education materials. Several nonparametric tests were used to …

Patient Satisfaction In A Statewide Cervical Cancer Screening Program, Christopher R. Cochran, Salome Kapella

Nevada Journal of Public Health

A cross-sectional study of patients participating in the Nevada State Health Division’s Women Health Connection Program (WHC) was conducted to assess patient satisfaction for cervical cancer screening. In this study, 528 WHC program patients provided information regarding their satisfaction with the treatment services they received, accessibility issues, breast and cervical cancer health education and information, and overall program satisfaction. A large majority of patients reported high levels of satisfaction with the program services and clinic personnel. Significant positive correlations were found when comparing satisfaction with services received at the clinic to treatment received by physicians, nurses, and admissions personnel, how …

Neurosteroid-Mediated Regulation Of Brain Innate Immunity In Hiv/Aids: Dhea-S Suppresses Neurovirulence, Amber Paul, Ferdinand G. Maingat, Maria J. Polyak, Pornpun Vivithanaporn, Farshid Noorbakhsh, Samir Ahboucha, Glen B. Baker, Keir Pearson, Christopher Power

Publications

Neurosteroids are cholesterol-derived molecules synthesized within the brain, which exert trophic and protective actions. Infection by human and feline immunodeficiency viruses (HIV and FIV, respectively) causes neuroinflammation and neurodegeneration, leading to neurological deficits. Secretion of neuroinflammatory host and viral factors by glia and infiltrating leukocytes mediates the principal neuropathogenic mechanisms during, although the effect of neurosteroids on these processes is unknown. We investigated the interactions between neurosteroid mediated effects and lentivirus infection outcomes. Analyses of HIV-infected uninfected human brains disclosed a reduction in neurosteroid synthesis enzyme expression. Human neurons exposed to supernatants from HIV macrophages exhibited suppressed enzyme expression without …

Health Disparities Experienced By People With Disabilities In The Us: A Behavioral Risk Factor Surveillance System Study, Jennifer Renee Pharr, Timothy J. Bungum

Environmental & Global Health Faculty Research

The Americans with Disabilities Act became law in 1990; since then research has shown that people with disabilities continue to experience barriers to health care. The purpose of this study was to compare utilization of preventive services, chronic disease rates, and engagement in health risk behaviors of participants with differing severities of disabilities to those without disabilities. This study was a secondary analysis of 2010 data collected in the Behavioral Risk Factor Surveillance System national survey in the United States. Rao Chi square test and logistic regression were employed. Participants with disabilities had significantly higher adjusted odds ratios for all …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Mobile health (mHealth) technologies hold incredible promise to improve healthcare delivery in resourcelimited settings. Network reliability across large catchment areas can be a major challenge. We performed an analysis of network failure frequency as part of a study of real-time adherence monitoring in rural Uganda. We hypothesized that the addition of short messaging service (SMS+GPRS) to the standard cellular network modality (GPRS) would reduce network disruptions and improve transmission of data.

Methods: Participants were enrolled in a study of real-time adherence monitoring in southwest Uganda. In June 2011, we began using Wisepill devices that transmit data each time the …

Development Of Repressible Systems To Control Gene Expression In Vaccinia Virus, Allison Titong

Master's Theses

Two vaccinia virus (VACV) expression systems that contain elements from the lactose (lac) and the tetracycline (tet) operons of E. coli were developed to repress the expression of a reporter gene, enhanced green fluorescent protein (EGFP), in the presence of tet operon inducers. In the first system, lac and tet operon elements were arranged in a gene circuit, and in the presence of increasing concentrations of a lac operon inducer (isopropyl-β-D-thiogalactoside, IPTG), EGFP expression increased in a dose dependent manner and at high IPTG concentrations, expression reached the same levels as a positive control virus. Importantly, in the …

Differential Virus Host-Ranges Of The Fuselloviridae Of Hyperthermophilic Archaea: Implications For Evolution In Extreme Environments, Ruben Michael Ceballos, Caleb D. Marceau, Joshua O. Marceau, Steven Morris, Adam J. Clore, Kenneth M. Stedman

Biological Sciences Faculty Publications and Presentations

An emerging model for investigating virus-host interactions in hyperthermophilic Archaea is the Fusellovirus-Sulfolobus system. The host, Sulfolobus, is a hyperthermophilic acidophile endemic to sulfuric hot springs worldwide. The Fuselloviruses, also known as Sulfolobus Spindle-shaped Viruses (SSVs), are “lemon” or “spindle”-shaped double-stranded DNA viruses, which are also found worldwide. Although a few studies have addressed the host-range for the type virus, Sulfolobus Spindle-shaped Virus 1 (SSV1), using common Sulfolobus strains, a comprehensive host-range study for SSV-Sulfolobus systems has not been performed. Herein, we examine six bona fide SSV strains (SSV1, SSV2, SSV3, SSVL1, SSVK1, SSVRH) and their respective infection characteristics on …

Murine Gammaherpesvirus 68 Lana Acts On Terminal Repeat Dna To Mediate Episome Persistence, Aline C. Habison, Chantal Beauchemin, J. Pedro Simas, Edward J. Usherwood

Dartmouth Scholarship

Murine gammaherpesvirus 68 (MHV68) ORF73 (mLANA) has sequence homology to Kaposi’s sarcoma-associated herpesvirus (KSHV) latency-associated nuclear antigen (LANA). LANA acts on the KSHV terminal repeat (TR) elements to mediate KSHV episome maintenance. Disruption of mLANA expression severely reduces the ability of MHV68 to establish latent infection in mice, consistent with the possibility that mLANA mediates episome persistence. Here we assess the roles of mLANA and MHV68 TR (mTR) elements in episome persistence. mTR-associated DNA persisted as an episome in latently MHV68-infected tumor cells, demonstrating that the mTR elements can serve as a cis-acting element for MHV68 episome maintenance. In some …

Refining The Global Spatial Limits Of Dengue Virus Transmission By Evidence-Based Consensus, Oliver J. Brady, Peter W. Gething, Samir Bhatt, Jane P. Messina, John S. Brownstein, Anne G. Hoen

Dartmouth Scholarship

Background: Dengue is a growing problem both in its geographical spread and in its intensity, and yet current global distribution remains highly uncertain. Challenges in diagnosis and diagnostic methods as well as highly variable national health systems mean no single data source can reliably estimate the distribution of this disease. As such, there is a lack of agreement on national dengue status among international health organisations. Here we bring together all available information on dengue occurrence using a novel approach to produce an evidence consensus map of the disease range that highlights nations with an uncertain dengue status.

Obstetrics and Gynaecology, East Africa

Background: Globally, studies report a high prevalence of intimate partner sexual violence (IPSV) and an association with HIV infection. Despite the criminalisation of IPSV and deliberate sexual HIV infection in Zimbabwe, IPSV remains common. This study explored women’s and health workers’ perspectives and experiences of sexuality and sexual violence in pregnancy, including in relation to HIV testing.

Methods: This qualitative study was part of a larger study of the dynamics of intimate partner violence and HIV in pregnancy in Zimbabwe. Key informant interviews were conducted with health workers and focus group discussions were held with 64 pregnant or nursing mothers …

Yeast Surface Display Of Cd154, Iaryna Masniuk

Graduate Theses and Dissertations

The CD154 (CD40L) is a member of tumor necrosis factor (TNF) family that plays a crucial role in regulation of both cell-mediated and humoral immunity by activating antigen presenting cells (APCs). Previously, studies in the laboratory demonstrated that yeast surface display system allows the expression of biologically functional antigen, such as subunit HA, against influenza virus. Yeast surface display system seems to be an excellent system to be utilized to develop anti-influenza virus vaccine. Thus, it is of interest to study the adjuvant function of CD154 on the subunit HA vaccine against influenza virus. In this project, the CD154 encoding …

Surveillance Of Mosquitoes For Arthropod-Borne Viruses In El Paso, Tx., Stephanie Coronado, Douglas Watts

COURI Symposium Abstracts, Summer 2012

West Nile encephalitis is the only arthropod-borne virus that causes annual cases of human illness in El Paso, Texas. Cases more commonly affect the young and elderly and the illness may range from a mild febrile disease to fatal encephalitis. The primary vector(s) of West Nile virus are Culex species mosquitoes, including Culex tarsalis and Culex quinquefaciatus. Further, surveillance is needed to determine the relative importance of these and possibly other mosquito species. More recently, cases of dengue fever and fatal hemorrhagic fever have been occurring in communities along the USA-Mexico border. Dengue has been endemic in Mexico since the …

In an effort to engage communities across the state of Massachusetts in tackling health disparities, Critical MASS (CM), in partnership with local researchers piloted a readiness assessment to identify community assets, perceptions of disparities, and interest in partnership. The research process was used to facilitate the development of partnerships between outside organizers, researchers, and community stakeholders. Partnership outcomes included a disparities conference aimed at bringing attention to concerns in the community, and a grant submission aimed at addressing community identified disparities. Despite the successes the partnership faced challenges. Logistics and limited resources hindered partner efforts to sustain the relationship. This …

Racial And Ethnic Health Disparities In Incarcerated Populations, Meghan E. Borysova, Ojmarrh Mitchell, Dawood H. Sultan, Arthur R. Williams

Journal of Health Disparities Research and Practice

Alarming disparities in population health and wellness in the United States have led to multi-disciplinary research efforts to create health equity. Identifying disparities, elucidating the etiological bases of disparities, and implementing solutions to eliminate disparities are part of the U.S. national health agenda. Racial and ethnic disparities have been identified throughout the cancer control continuum, in cardiovascular disease, diabetes and a multitude of other conditions. The causes of disparities are complex, condition specific, and conjectured to result from combinations of biological and socio-behavioral factors. Racial and ethnic health disparities within the vast incarcerated communities have been excluded from most studies, …

Disparities In Mental Health Utilization Among Persons With Chronic Diseases, Saundra Glover, Keith Elder, Sudha Xirasagar, Jong-Deuk Baek, Crystal Piper, Dayna Campbell

Journal of Health Disparities Research and Practice

This study used Aday and Andersen’s Behavioral Model of Health Services Use to examine the role of chronic disease and the joint impact of race and chronic disease type on mental health utilization. Using data from Community Tracking Survey Household Survey, we tested the assumption that chronic disease, chronic disease type, and race are related to lower rates of mental health visits when adjusted for predisposing, enabling, and need factors. After adjusting for population characteristics, we found that race significantly moderated the impact of chronic disease type on mental health utilization, showing that African Americans with cardiovascular disease were half …

Developing A Preference Assessment Tool For Use Among Minority And Low Literacy Primary Care Patients, Sarah T. Hawley, Maria Jibaja-Weiss, Partha Krishnamurthy, Sally W. Vernon, Natoshia Hebert, Robert Volk

Journal of Health Disparities Research and Practice

Incorporating patients’ preferences into healthcare decisions has been identified as one mechanism for reducing health disparities. Some research suggests that providers need to tailor medical recommendations to the preferences of their patients. Yet there are few tools to facilitate clarification of preferences for health services. This paper reports the process of testing an innovative preference elicitation technique—conjoint analysis—among minorities and low literacy patients using the example of colorectal cancer (CRC) screening. CRC screening exemplifies preference-sensitive healthcare as there exist several screening options. However, screening rates among minorities are low. Better methods for preference assessment could improve patient-provider communication and increase …

The Hiv/Aids Pandemic In African American Msm: Targets For Intervention, Kelly Neff

Journal of Health Disparities Research and Practice

The Centers for Disease Control and Prevention estimated in 2005 that 46% of African American men who have sex with men (MSM) are HIV positive. This review explores the unique factors that contribute to risky sexual behavior and the spread of HIV within this population, suggesting that the disparate prevalence of HIV among African American MSM is rooted in experiences of stigmatization from multiple sources and lack of social support from society at large as well as from within the African American community. Beliefs in HIV conspiracy myths are also thought to hinder HIV education, awareness and prevention for African …

Transdisciplinary Approaches To Ameliorating Racial Disparities In Prostate Cancer Outcomes, Chanita H. Halbert, Katrina Armstrong, John Holmes, David Fenstermacher, Janet Weiner, Carmen Guerra, J. S. Schwartz, Jerry C. Johnson, Edmund Weisberg, Chantal Montagnet, Benita Weathers, Charnita Zeigler-Johnson, Ernestine Delmoor, Timothy R. Rebbeck

Journal of Health Disparities Research and Practice

Though prostate cancer is the second leading cause of cause cancer deaths among men in the US, it ranks first among African American men in terms of incidence, morbidity, and mortality. To address this and other complex health issues, some researchers advocate transdisciplinary research as a framework for analysis; however, few examples exist that indicate how the framework should be applied. This report uses prostate cancer outcomes as a paradigm to describe how such a framework can be used to identify determinants of racial disparities. By integrating diverse scientific disciplines, methods, and analytic approaches from psychology, sociology, epidemiology and genetics, …

A Pilot Self-Care Group Intervention For Low-Income Hiv-Positive Women, Maithe Enriquez, Margaret S. Miles, Jacki Witt, Paul Gore, Nancy Lackey

Journal of Health Disparities Research and Practice

This article describes the development of a self-care intervention and examines its efficacy with low-income HIV-positive women (n=34) in the Midwestern United States. Adapted from an individual nurse-led intervention, this effort focused on increasing self-care behaviors through enhancing self-esteem and social support. The investigators used a community-based participatory approach and partnered with three HIV-positive women to adapt and pilot test the new group intervention. A within-group, repeated-measures, pre-/post-test design, together with participant interviews, was used to evaluate the intervention. Mean scores on measures of self-care behaviors, self-esteem, social support and depressive symptoms all changed in the clinically desirable direction. Group …

Health Literacy As A Contributor To Immigrant Health Disparities, Jennifer B. Kimbrough

Journal of Health Disparities Research and Practice

The ability to obtain, understand and use the information needed to make wise health choices is known as health literacy. Low health literacy among members of populations with poor reading skills, limited mastery of the English language, members of ethnic or cultural minorities, and immigrants is likely a major contributor to health disparities in the US (Agency for Health Care Policy and Research 1997). A series of focus groups with East-Asian, African, Central and South American immigrants was conducted to better understand the perceptions of immigrants seeking health care services in an urban North Carolina county. Participants’ responses are reported …

Cumulative Risk And A Call For Action In Environmental Justice Communities, H. P. Hynes, Russ Lopez

Journal of Health Disparities Research and Practice

Health disparities, social inequalities, and environmental injustice cumulatively affect individual and community vulnerability and overall health; yet health researchers, social scientists and environmental scientists generally study them separately. Cumulative risk assessment in poor, racially segregated, economically isolated and medically underserved communities needs to account for their multiple layers of vulnerability, including greater susceptibility, greater exposure, less preparedness to cope, and less ability to recover in the face of exposure. Recommendations for evidence-based action in environmental justice communities include: reducing pollution in communities of highest burden; building on community resources; redressing inequality when doing community-based research; and creating a screening framework …

Eliminating Racial/Ethnic Health Disparities: Reconsidering Comparative Approaches, Shawn M. Bediako, Derek M. Griffith

Journal of Health Disparities Research and Practice

The focus on eliminating racial/ethnic health disparities has brought critical attention to the poor health status of minority populations. Assessing the health outcomes of racial minority groups by comparing them to a racial majority standard is valuable for identifying and monitoring health inequities, but may not be the most effective approach to identifying strategies that can be used to improve minority health outcomes. Health promotion planning models and public health history both suggest that minority health promotion is more likely to be derived from interventions rooted in culturally and historically grounded contextual factors. In this essay, we highlight limitations of …
