A Review Of Case-Control And Cohort Studies Examining Pesticides And The Risk Of Parkinson's Disease, Ruth Moytca Parks

International Journal of Global Health and Health Disparities

Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer disease, having an annual incidence of approximately 20 per 100,000 people (Schapira 2004, Fischer 1999). An estimated one million persons in the United States have PD, and this prevalence is likely to rise as the population ages (Schapira 2004). This disorder is characterized pathologically by a loss of dopamine neurons in the substantia nigra pars compacta that produces the neurotransmitter dopamine. The clinical features of PD are motor function abnormalities including tremor, rigidity, slowness of movement, and difficulty with balance. In the early stages of PD, treatments may …

Responsibility For Hiv Prevention: Patterns Of Attribution Among Hiv-Seropositive Gay And Bisexual Men, C. Offer, O. Grinstead, E. Goldstein, Edward M. Mamary, N. Alvarado, J. Euren, W. Woods

Faculty Publications

The article presents research based on narratives by gay and bisexual men recently infected with HIV. Researchers looked at the men's attributions of responsibility for infection, comparing recollections of feelings before becoming infected with views expressed after seroconversion. The research responds to a call to better understand risk behavior among HIV-positive persons, in an effort to craft effective prevention interventions. In both before-and after-HIV infection views, survey participants expressed a sense of personal responsibility. Researchers report also nuances of views about shared responsibility.

Investigating The Effects Of An Elective Abortion On Women's Mental Health, Marilyn Schneiderman

Graduate Research Papers

The purpose of this research project is to investigate evidence that an elective abortion affects a woman's mental health. Included are literature reviews and studies aimed at gathering information and quantifying these effects. Because this is a highly politicized and controversial topic, it has been difficult to find objective resources. Several areas are addressed: the difference between short vs. long-term effects on a woman's mental health subsequent to an elective abortion, evidence of delayed grief reaction and the link with post-traumatic stress disorder (PTSD). Post-Abortion Stress is defined and specific psychological sequelae are addressed such as grief, depression, anxiety and …

Post-Operative Extended Volume External Beam Radiation Therapy Is Safe For High Risk Esophageal Cancer Patients, Edward Yu, Patricia Tai, Jawaid Younus, Richard Malthaner, Larry Stitt, Pauline Truong, George Rodrigues, Robert Ash, Rashid Dar, Anna Tomiak, Mark Vincent, Walter Kocha, Brian Dingle, Richard Inculet

Oncology Presentations

Post-operative radiation therapy (RT) (1) and post-operative chemoradiation (2) have been used for esophageal cancer patients deemed high risk for recurrence after esophagectomy.

Defining opitmal RT target volume after esophagectomy is difficult due to significant changes in patient anatomy and function.

Some radiationon cologists advocated the inclusion of the anastomotic site within the irradiation volume due to concerns for potential increased relapse risk, while others did not subscribe to this practice due to concerns for increased treatment related toxicity.

We have previously reported patient outcome benefit using extended volume RT In management with high risk esophageal cancer patients underwent esopagectomy(3). …

Social Support And Thriving Health: A New Approach To Understanding The Health Of Indigenous Canadians, Chantelle A.M. Richmond, Nancy A. Ross, Grace E. Egeland

Aboriginal Policy Research Consortium International (APRCi)

Objectives. We examined the importance of social support in promoting thriv- ing health among indigenous Canadians, a disadvantaged population.

Methods. We categorized the self-reported health status of 31 625 adult indig- enous Canadians as thriving (excellent, very good) or nonthriving (good, fair, poor). We measured social support with indices of positive interaction, emotional support, tangible support, and affection and intimacy. We used multivariable lo- gistic regression analyses to estimate odds of reporting thriving health, using social support as the key independent variable, and we controlled for educational attainment and labor force status.

Results. Compared with women reporting low levels of …

Learning From The Grandmothers: Incorporating Indigenous Principles Into Qualitative Research, Charlotte Loppie

Aboriginal Policy Research Consortium International (APRCi)

In this article, the author describes the process she undertook to incorporate Indigenous principles into her doctoral research about the midlife health experiences of elder Aboriginal women in Nova Scotia, Canada. By employing qual- itative methods within the context of an Indigenous worldview, she gained knowledge of and developed competence in Aboriginal health research. The emergent partnership among Aboriginal community research facilitators, participating Mi’kmaq women, and the researcher provided many opportunities for the researcher to incorporate the paradigmatic and methodological traditions of Western science and Indigenous cultures. The application of these principles to this study might provide a useful example …

Evaluation Of A Behavioral Health Integration Program In A Rural Primary Care Facility, Tina W. Billmeyer

Theses, Dissertations and Capstones

Behavioral or mental health has historically been seen as a separate entity from medical or primary health care. With the increased utility of psychotropic medication, more and more patients are presenting to their primary care provider with behavioral health issues prompting the healthcare field to look for methods to integrate medical and behavioral health services. The current study examined the effectiveness of a pilot program that attempted to integrate services at a rural primary care clinic. The study asked whether participation in the program resulted in improved scores on a questionnaire of perceived health status and whether participating medical providers …

Disclosure Of Maternal Hiv Status To Children: To Tell Or Not To Tell . . . That Is The Question, Tanya L. Tompkins

Faculty Publications

HIV-infected mothers face the challenging decision of whether to disclose their serostatus to their children. From the perspective of both mother and child, we explored the process of disclosure, providing descriptive information and examining the relationships among disclosure, demographic variables, and child adjustment. Participants were 23 mothers and one of their noninfected children (9 to 16 years of age). Sixty-one percent of mothers disclosed. Consistent with previous research, disclosure was not related to child functioning. However, children sworn to secrecy demonstrated lower social competence and more externalizing problems. Differential disclosure, which occurred in one-third of the families, was associated with …

Parentification And Maternal Hiv Infection: Beneficial Role Or Pathological Burden?, Tanya L. Tompkins

Faculty Publications

Parentification, along with parenting and child adjustment were examined in 23 9-through 16-year-old youth from families affected by maternal HIV infection and 20 same-age peers whose mothers were not infected. Children whose mothers were HIV-positive reported to more often engage in parental role behaviors, relative to children of HIV-negative mothers. This difference remained even after controlling for the effects of current drug use, number of adults per child in the household, and marital status. Findings revealed a beneficial relationship between parentification and both child adjustment and parenting, particularly among families affected by maternal HIV infection. When relationships were examined separately …

The Use Of Telehealth For Diabetes Management: A Qualitative Study Of Telehealth Provider Perceptions, Faith P. Hopp, Mary M. Hogan, Peter A. Woodbridge, Julie C. Lowery

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Monitoring and Messaging Devices (MMDs) are telehealth systems used by patients in their homes, and are designed to promote patient self-management, patient education, and clinical monitoring and follow-up activities. Although these systems have been widely promoted by health care systems, including the Veterans Health Administration, very little information is available on factors that facilitate use of the MMD system, or on barriers to use.

Methods

We conducted in-depth qualitative interviews with clinicians using MMD-based telehealth programs at two Veterans Affairs Medical Centers in the Midwestern United States.

Results

Findings suggest that MMD program enrollment is limited by both …

Inhibition Of Proteasome Activity By The Dietary Flavonoid Apigenin Is Associated With Growth Inhibition In Cultured Breast Cancer Cells And Xenografts, Di Chen, Kristin R. Landis-Piwowar, Marina S. Chen, Q Ping Dou

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Proteasome inhibition is an attractive approach to anticancer therapy and may have relevancy in breast cancer treatment. Natural products, such as dietary flavonoids, have been suggested as natural proteasome inhibitors with potential use for cancer prevention and therapeutics. We previously reported that apigenin, a flavonoid widely distributed in many fruits and vegetables, can inhibit proteasome activity and can induce apoptosis in cultured leukemia Jurkat T cells. Whether apigenin has proteasome-inhibitory activity in the highly metastatic human breast MDA-MB-231 cells and xenografts, however, is unknown.

Methods

MDA-MB-231 breast cancer cell cultures and xenografts were treated with apigenin, followed by …

Examining Smoking And Cessation During Pregnancy Among An Appalachian Sample: A Preliminary View, Lesley Cottrell, Mark Gibson, Carole Harris, Alia Rai, Sabera Sobhan, Traci Berry, Bonita Stanton

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Several transitions that a woman experiences prenatally may influence her desire or ability to discontinue smoking. This study explores the role of smoking for young, Appalachian, nulliparous pregnant women and their plans for smoking during their pregnancies.

Results

The reports of women and their male partners were taken from baseline interviews conducted during the first trimester of pregnancy. Cigarette smoking appeared to be more than an isolated addictive activity; rather, smoking was interwoven in women's social and personal realms, often changing as their perceptions of self changed. Women and their partners who continued to smoke appeared to be …

Paradoxical Antiproliferative Effect By A Murine Mammary Tumor-Derived Epithelial Cell Line, Esteban N. Gurzov, Sanaa M. Nabha, Hamilto Yamamoto, Hong Meng, O Graciela Scharovsky, R Daniel Bonfil

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Despite significant advancement in breast cancer therapy, there is a great need for a better understanding of the mechanisms involved in breast carcinogenesis and progression, as well as of the role of epigenetic contributions from stromal cells in mammary tumorigenesis. In this study, we isolated and characterized murine mammary tumor-derived epithelial and myofibroblast cell lines, and investigated the in vitro and in vivo effect of cellular soluble factors produced by the epithelial cell line on tumor cells.

Methods

Morphology, immunophenotype, cytogenetics, invasiveness, and tumorigenicity of epithelial (LM-234ep) and myofibroblast (LM-234mf) cell lines isolated from two murine mammary adenocarcinomas …

The Class Ii Major Histocompatibility Complex Molecule Bola-Dr Is Expressed By Endothelial Cells Of The Bovine Corpus Luteum, Matthew J. Cannon, John S. Davis, Joy L. Pate

United States Public Health Resources

Cells expressing class II major histocompatibility complex (MHC) molecules are found within the corpus luteum (CL) of several species. Expression and localization of class II MHC molecules in the bovine CL were examined in the present study. Immunohistochemical evaluation revealed class II MHC molecules on single cells in early CL (days 4 and 5 post-estrus). Two class II MHC-expressing cell types were observed in midcycle CL (days 10–12 post-estrus), single cells similar to those observed in the early CL, and endothelial cells. Not all endothelial cells expressed class II MHC, and further investigation revealed expression of only one type of …

Global Scale Climate–Crop Yield Relationships And The Impacts Of Recent Warming, David Lobell, Christopher Field

United States Public Health Resources

Changes in the global production of major crops are important drivers of food prices, food security and land use decisions. Average global yields for these commodities are determined by the performance of crops in millions of fields distributed across a range of management, soil and climate regimes. Despite the complexity of global food supply, here we show that simple measures of growing season temperatures and precipitation—spatial averages based on the locations of each crop—explain ∼30% or more of year-to-year variations in global average yields for the world’s six most widely grown crops. For wheat, maize and barley, there is a …

Demographic Factors Associated With Prevalence Of Antibody To Sin Nombre Virus In Deer Mice In The Western United States, Charles Calisher, Kent Wagoner, Brian Amman, J. Jeffrey Root, Richard J. Douglass, Amy Kuenzi, Ken Abbott, Cheryl Parmenter, Terry Yates, Thomas Ksiazek, Barry J. Beaty, James N. Mills

United States Public Health Resources

We used long-term data collected for up to 10 yr (1994–2004) at 23 trapping arrays (i.e., webs and grids) in Arizona, Colorado, Montana, and New Mexico to examine demographic factors known or suspected to be associated with risk of infection with Sin Nombre virus (SNV) in its natural host, the deer mouse (Peromyscus maniculatus). Gender, age (mass), wounds or scars, season, and local relative population densities were statistically associated with the period prevalence of antibody (used as a marker of infection) to SNV in host populations. Nevertheless, antibody prevalence and some of the risk factors associated with antibody …

Identification Of Vibrio Isolates By A Multiplex Pcr Assay And Rpob Sequence Determination, Cheryl L. Tarr, Jayna S. Patel, Nancy Puhr, Evangeline Sowers, Cheryl A. Bopp, Nancy A. Strockbine

United States Public Health Resources

Vibrio, a diverse genus of aquatic bacteria, currently includes 72 species, 12 of which occur in human clinical samples. Of these 12, three species—Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus—account for the majority of Vibrio infections in humans. Rapid and accurate identification of Vibrio species has been problematic because phenotypic characteristics are variable within species and biochemical identification requires 2 or more days to complete. To facilitate the identification of human-pathogenic species, we developed a multiplex PCR that uses species-specific primers to amplify gene regions in four species (V. cholerae, V. parahaemolyticus, V. …

Participants learn behaviour-changing skills tailored to low-income populations, such as collaborative goal setting, the need to take small steps and other empowerment techniques.

Aim: To quantify the baseline prevalence of pre-diabetes (fasting blood glucose 5.5–6.9 mmol/l) and diabetes among WISEWOMAN participants and assess one year changes in glucose levels and other diabetes risk factors.

Methods: We used 1998–2005 baseline and one-year follow-up data from WISEWOMAN participants. Using a multilevel regression model, we assessed …

A Scale-Free Systems Theory Of Motivation And Addiction, R. Andrew Chambers, Warren K. Bickel, Marc N. Potenza

United States Public Health Resources

Scale-free organizations, characterized by uneven distributions of linkages between nodal elements, describe the structure and function of many life-based complex systems developing under evolutionary pressures. We explore motivated behavior as a scale-free map toward a comprehensive translational theory of addiction. Motivational and behavioral repertoires are reframed as link and nodal element sets, respectively, comprising a scale-free structure. These sets are generated by semi-independent information-processing streams within cortical–striatal circuits that cooperatively provide decision-making and sequential processing functions necessary for traversing maps of motivational links connecting behavioral nodes. Dopamine modulation of cortical–striatal plasticity serves a central-hierarchical mechanism for survival-adaptive sculpting and development …

Are Smokers Only Using Cigarettes? Exploring Current Polytobacco Use Among An Adult Population, Jennifer M. Bombard, Linda L. Pederson, David E. Nelson, Ann M. Malarcher

United States Public Health Resources

Background: The primary focus of tobacco prevention and cessation interventions has been on cigarette smoking. Polytobacco use (the concurrent use of cigarettes and one or more other tobacco product[s]), may present additional health risks and make cessation more difficult.
Methods: We determined population estimates of tobacco product use and of polytobacco use for more than 50000 adults from 10 states. Logistic regression analyses were used to determine factors independently associated with polytobacco use among men only (due to low use among women).
Results: The overall adult prevalence was 22.4% for cigarettes and 3.4% for polytobacco use. Polytobacco use was more …

Relaxin Receptors In Hepatic Stellate Cells And Cirrhotic Liver, Robert G. Bennett, Shana R. Dalton, Katrina J. Mahan, Martha J. Gentry-Nielsen, Frederick G. Hamel, Dean J. Tuma

United States Public Health Resources

The polypeptide hormone relaxin has antifibrotic effects on a number of tissues, including the liver. Central to the progression of hepatic fibrosis is the transdifferentiation of hepatic stellate cells (HSC) from a quiescent state to an activated, myofibroblastic phenotype that secretes fibrillar collagen. Relaxin inhibits markers of HSC activation, but relaxin receptor expression in the liver is unclear. The purpose of this study was to determine the expression of the relaxin receptors LGR7 and LGR8 in activated HSC. Production of cAMP was induced by treatment of HSC with relaxin, or the relaxin-related peptides InsL3 or relaxin-3, selective activators of LGR8 …

Performance Of A Commercial Immunoglobulin M Antibody Capture Assay Using Analyte-Specific Reagents To Screen For Interfering Factors During A West Nile Virus Epidemic Season In Nebraska, Anthony R. Sambol, Steven H. Hinrichs, Wayne R. Hogrefe, Beth K. Schweitzer

United States Public Health Resources

In 2003, the Nebraska Public Health Laboratory tested more than 10,371 serum and 516 cerebral spinal fluid specimens. Results showed that without performing the interfering factors screen for specimens in the low positive index value range of >1.1 to ≤3.5, a false positivity rate of 6.5% would have been realized.

Comparative Genetic Analysis Of Genomic Dna Sequences Of Two Human Isolates Of Tanapox Virus, Steven H. Nazarian, John W. Barrett, A. Michael Frace, Melissa Olsen-Rasmussen, Marina Khristova, Mae Shaban, Sarah Neering, Yu Li, Inger K. Damon, Joseph J. Esposito, Karim Essani, Grant Mcfadden

United States Public Health Resources

Members of the genus Yatapoxvirus, which include Tanapox virus (TPV) and Yaba monkey tumor virus, infect primates including humans. Two strains of TPV isolated 50 years apart from patients infected from the equatorial region of Africa have been sequenced. The original isolate from a human case in the Tana River Valley, Kenya, in 1957 (TPV-Kenya) and an isolate from an infected traveler in the Republic of Congo in 2004 (TPV-RoC). Although isolated 50 years apart the genomes were highly conserved. The genomes differed at only 35 of 144,565 nucleotide positions (99.98% identical). We predict that TPV-RoC encodes 155 …

Social Capital And Rates Of Gonorrhea And Syphilis In The United States: Spatial Regression Analyses Of State-Level Associations, Salaam Semaan, Maya Sternberg, Akbar Zaidi, Sevgi O. Aral

United States Public Health Resources

We conducted spatial regression analysis to account for spatial clustering of sexually transmitted diseases (STDs) and to examine the state-level association between social capital (using Putnam’s public use data set) and rates of gonorrhea and syphilis. We conducted the analysis for the 48 contiguous states of the United States for 1990, 1995, and 2000 and controlled for the effects of regional variation in STD rates, and for state variation in poverty, income inequality, racial composition, and percentage aged 15–34 years. We compared the results of the spatial regression analysis with those of ordinary least squares (OLS) regression. Controlling for all …
