The Effect Of An Educational Intervention On Knowledge And Intent To Participate In Cervical Cancer Screening, Ann Marie Trapp May 2015

The Effect Of An Educational Intervention On Knowledge And Intent To Participate In Cervical Cancer Screening, Ann Marie Trapp

Evidence-Based Practice Project Reports

Globally, cervical cancer ranks third among cancers affecting women (Arbyn et al., 2013). In the United States, approximately 12,000 women are diagnosed with cervical cancer and approximately 4,000 women die yearly (Centers for Disease Control and Prevention, 2014). Papanicolaou (Pap) screening is an effective means of detecting precancerous cell changes of the cervix with early cervical cancer diagnosis carrying a 91% five-year survival rate (Gonzalez et al., 2012). The purpose of this evidence-based practice project was to identify interventions that increase adherence to cervical cancer screening and to implement best practices to reduce unnecessary deaths related to late diagnoses of …


Fracture Toughness Of Irradiated Bone In A Murine Model, Lynda Marie Brady May 2015

Fracture Toughness Of Irradiated Bone In A Murine Model, Lynda Marie Brady

Renée Crown University Honors Thesis Projects - All

Cancer is a prevalent and diverse disease affecting fourteen million people in the United Sates alone. While some cancers can be treated effectively with one-time operations such as surgery, other cancers require more persistent treatments, commonly chemotherapy and radiation. These latter two treatments can have extreme side-effects and long-term ramifications. One long-term side effect of radiation therapy is a higher incidence of insufficiency fractures in bones of the skeleton. The mechanism responsible for this apparent weakness in bone is not well understood. In order to quantify changes in ductility following radiation therapy, femora from mice treated with 20 Gy radiation …


A Comparison Of Cyfra 21-1, Nse, And Cea For The Serodiagnosis Of Lung Cancer, A Alexandra Knopp May 2015

A Comparison Of Cyfra 21-1, Nse, And Cea For The Serodiagnosis Of Lung Cancer, A Alexandra Knopp

Honors Theses

There were 224,210 new cases of lung cancer in the US during 2014, and of those cases, there 159,260 that died from lung cancer during 2014. Since early diagnosis and treatment leads to a better prognosis, the medical community is actively looking for new, noninvasive tests for the disease. This includes the search for new and effective tumor markers. Tumor markers are used in combination with other tests to diagnose cancer. After the diagnosis, they are used to follow a patient’s case. The three tumor markers studied were neuron specific enolase (NSE), carcinoembryonic antigen (CEA), and CYFRA 21-1. In this …


Tumor Promoting Properties Of Field Cancerized Fibroblasts In Cell Culture, Randi L. Smith May 2015

Tumor Promoting Properties Of Field Cancerized Fibroblasts In Cell Culture, Randi L. Smith

Biomedical Sciences ETDs

Our recent studies have shown that Tumor Adjacent Histologically Normal (TAHN) breast tissue demonstrates many of the characteristics of breast tumors. For example, through immunohistochemical staining with markers such as alpha smooth muscle actin and TGF-β, we have shown the accumulation of myofibroblasts in TAHN tissues 1 cm from the tumor margin (TAHN-1). Additionally, TAHN-1 epithelia stain positive for epithelial to mesenchymal transition (EMT) associated proteins, such as transforming growth factor beta and alpha smooth muscle actin. The purpose of this study was to determine if TAHN-1 fibroblasts retained myofibroblast characteristics and if they could induce EMT in primary culture. …


Multilevel Deregulation Of Survival Mechanisms In Npm-Alk+ T-Cell Lymphoma, Deeksha Vishwamitra May 2015

Multilevel Deregulation Of Survival Mechanisms In Npm-Alk+ T-Cell Lymphoma, Deeksha Vishwamitra

Dissertations and Theses (Open Access)

The anaplastic lymphoma kinase (ALK) is a single chain transmembrane receptor tyrosine kinase that belongs to the insulin receptor superfamily. Other members of this superfamily include the insulin receptor (IR), type I insulin-like growth factor receptor (IGF-IR), and the leukocyte tyrosine kinase. The common structural finding among these tyrosine kinases is the YXXXYY motif present within their respective tyrosine kinase domains. Binding of its ligands causes ALK receptor homodimerization and protein kinase activation. ALK has been previously shown to play a significant role during early developmental stages. In human embryos, the expression of ALK is mainly seen in …


Killer Cell Activation By A Novel Multifunctional Protein: An Immuno/Gene Therapy For Cancer, Ashlee Tietje May 2015

Killer Cell Activation By A Novel Multifunctional Protein: An Immuno/Gene Therapy For Cancer, Ashlee Tietje

All Dissertations

One of the characteristics of advanced tumors is the evasion of the immune system. There are multiple methods that tumor cells employ to achieve this including reducing the expression of activating ligands on the cell surface and a shift in the tumor microenvironment toward pro-tumor cytokines. The purpose of this research is to develop a novel bifunctional fusion protein that will target these two deficiencies in the tumor microenvironment and activate killer cells that are already present. The proposed protein combines the extracellular domain of a ligand for the killer cell activating receptor NKG2D and Interleukin-12 (IL-12). It is hypothesized …

Usefulness Of A Patient Experience Study To Adjust Psychosocial Oncology And Spiritual Care Services According To Patients’ Needs, Lynda Belanger, Francois Rainville, Martin Coulombe, Annie Tremblay

Patient Experience Journal

Little is known about how cancer patients experience psychosocial and spiritual care services and about what services they feel should be offered in order to help them meet their actual needs. This study’s main goal was to examine how cancer patients experienced the psychosocial oncology and spiritual care (POSC) services they received, in order to adjust the service offer according to their expressed needs and expectancies. A qualitative design approach was used. The study was conducted in two phases: (1) Collection of the patients’ perspective and divulgation of the results to the clinical team and managers; and (2) assessment of …

Curcumin Induces Apoptosis Of Upper Aerodigestive Tract Cancer Cells By Targeting Multiple Pathways, Arm R. Amin, A. Haque, M. A. Rahman, Z. G. Chen, F. R. Khuri, D. M. Shin

Pharmaceutical Science and Research

Curcumin, a natural compound isolated from the Indian spice "Haldi" or "curry powder", has been used for centuries as a traditional remedy for many ailments. Recently, the potential use of curcumin in cancer prevention and therapy urges studies to uncover the molecular mechanisms associated with its anti-tumor effects. In the current manuscript, we investigated the mechanism of curcumin-induced apoptosis in upper aerodigestive tract cancer cell lines and showed that curcumin-induced apoptosis is mediated by the modulation of multiple pathways such as induction of p73, and inhibition of p-AKT and Bcl-2. Treatment of cells with curcumin induced both p53 and the …

Methods: We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans.

Results: To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other …


Community-Based Participatory Research Principles For The African American Community, Selina A. Smith, Mary S. Whitehead, Joyce Q. Sheats, Benjamin E. Ansa, Steven S. Coughlin, Daniel S. Blumenthal Apr 2015

Community-Based Participatory Research Principles For The African American Community, Selina A. Smith, Mary S. Whitehead, Joyce Q. Sheats, Benjamin E. Ansa, Steven S. Coughlin, Daniel S. Blumenthal

Journal of the Georgia Public Health Association

Background: Numerous sets of principles have been developed to guide the conduct of community-based participatory research (CBPR). However, they tend to be written in language that is most appropriate for academics and other research professionals; they may not help lay people from the community understand CBPR.

Methods: Many community members of the National Black Leadership Initiative on Cancer assisting with the Educational Program to Increase Colorectal Cancer Screening (EPICS) had little understanding of CBPR. We engaged community members in developing culturally-specific principles for conducting academic-community collaborative research.

Results: We developed a set of CBPR principles intended to resonate with African-American …

Fluoxetine Prevents The Development Of Depressive-Like Behavior In A Mouse Model Of Cancer Related Fatigue, Diana M. Norden, Raymond Devine, Sabahattin Bicer, Runfeng Jing, Peter J. Reiser, Loren E. Wold, Jonathan P. Godbout, Donna O. Mccarthy Mar 2015

Fluoxetine Prevents The Development Of Depressive-Like Behavior In A Mouse Model Of Cancer Related Fatigue, Diana M. Norden, Raymond Devine, Sabahattin Bicer, Runfeng Jing, Peter J. Reiser, Loren E. Wold, Jonathan P. Godbout, Donna O. Mccarthy

College of Nursing Faculty Research and Publications

Cancer patients frequently suffer from fatigue, a complex syndrome associated with tiredness and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, escalates during treatment, and can persist for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with decreased survival in patients with incurable disease. We have previously shown that increased pro-inflammatory cytokine expression in the brain contributes to depressive- and fatigue-like behaviors in a mouse model of CRF. Inflammatory cytokines increase the activity of indoleamine 2,3-dioxygenase (IDO) and kynurenine 3-monooxygenase (KMO), which competitively reduce serotonin synthesis. Reduced serotonin …

United States Public Health Resources

Over the past decade, it has become evident that the microbiome is an important environmental factor that affects many physiological processes, such as cell proliferation and differentiation, behaviour, immune function and metabolism. More importantly, it may contribute to a wide variety of diseases, including cancer, inflammatory diseases, metabolic diseases and responses to pathogens. We expect that international, integrative and interdisciplinary translational research teams, along with the emergence of FDA-approved platforms, will set the framework for microbiome-based therapeutics and diagnostics. We recognize that the microbiome ecosystem offers new promise for personalized/precision medicine and targeted treatment for a variety of diseases. The …

Active Immunotherapy And Adoptive Cell Transfer As An Effective Cancer Treatment, Philip Jay Cynamon Jan 2015

Active Immunotherapy And Adoptive Cell Transfer As An Effective Cancer Treatment, Philip Jay Cynamon

The Science Journal of the Lander College of Arts and Sciences

There are many ways to fight cancer using the body’s own immune system. Some methods include the administration of vaccines while others involve stimulatory factors injected near tumors. One promising method is enlisting the help of T cells. To fight cancer effectively, T cells must be able to recognize cancerous antigens and the environment in which these T cells reside must be conducive to their function, survival, and proliferation. This paper discusses a method of providing such an environment called adoptive cell transfer, as well as the elements that effect this protocol and the ways in which the environment can …


Cancer Stem Cells In The Screening Of Anticancer Drugs For Central Nervous System Tumors, Sarah Elizabeth Daron-Mathis Jan 2015

Cancer Stem Cells In The Screening Of Anticancer Drugs For Central Nervous System Tumors, Sarah Elizabeth Daron-Mathis

Theses, Dissertations and Capstones

There is a growing need (in the medical field) to design personalized therapy for cancer patients. Decades of cancer research have found no silver bullet that can cure all or even most patients. This study evaluated four patients affected by central nervous system (CNS) tumors (Ependymoma and Glioblastoma), and found that tumors with the same histology had unique responses to treatment. Each sample presented different levels of heterogeneity in expressed biomarkers and responded to drugs at varying levels.

Oncologists conventionally treat cancer patients with drugs tested in large clinical trials. However, often patients do not experience positive outcomes following treatments …

Human Cytomegalovirus Interleukin-10 Promotes Proliferation And Migration Of Mcf-7 Breast Cancer Cells, Robin K. Bishop, Cendy A. Valle Oseguera, Juliet Spencer

Biology Faculty Publications

Breast cancer is the most common malignancy affecting women worldwide. While a small fraction of breast cancers have a hereditary component, environmental and behavioral factors also impact the development of cancer. Human cytomegalovirus (HCMV) is a member of the Herpesviridae family that is widespread in the general population and has been linked to several forms of cancer. While HCMV DNA has been found in some breast cancer tissue specimens, we wanted to investigate whether a secreted viral cytokine might have an effect on cancerous or even pre-cancerous cells. HCMV encodes an ortholog of the human cellular cytokine interleukin-10 (IL-10). The …

Catchment Area Analysis Using Bayesian Regression Modeling, Aobo Wang, David C. Wheeler Jan 2015

Catchment Area Analysis Using Bayesian Regression Modeling, Aobo Wang, David C. Wheeler

Biostatistics Publications

A catchment area (CA) is the geographic area and population from which a cancer center draws patients. Defining a CA allows a cancer center to describe its primary patient population and assess how well it meets the needs of cancer patients within the CA. A CA definition is required for cancer centers applying for National Cancer Institute (NCI)-designated cancer center status. In this research, we constructed both diagnosis and diagnosis/treatment CAs for the Massey Cancer Center (MCC) at Virginia Commonwealth University. We constructed diagnosis CAs for all cancers based on Virginia state cancer registry data and Bayesian hierarchical logistic regression …


Evaluation Of The Performance Of Smoothing Functions In Generalized Additive Models For Spatial Variation In Disease, Umaporn Siangphoe, David C. Wheeler Jan 2015

Evaluation Of The Performance Of Smoothing Functions In Generalized Additive Models For Spatial Variation In Disease, Umaporn Siangphoe, David C. Wheeler

Biostatistics Publications

Generalized additive models (GAMs) with bivariate smoothing functions have been applied to estimate spatial variation in risk for many types of cancers. Only a handful of studies have evaluated the performance of smoothing functions applied in GAMs with regard to different geographical areas of elevated risk and different risk levels. This study evaluates the ability of different smoothing functions to detect overall spatial variation of risk and elevated risk in diverse geographical areas at various risk levels using a simulation study. We created five scenarios with different true risk area shapes (circle, triangle, linear) in a square study region. We …


Penalized Ordinal Regression Methods For Predicting Stage Of Cancer In High-Dimensional Covariate Spaces, Amanda Elswick Gentry, Colleen K. Jackson-Cook, Debra E. Lyon, Kellie J. Archer Jan 2015

Penalized Ordinal Regression Methods For Predicting Stage Of Cancer In High-Dimensional Covariate Spaces, Amanda Elswick Gentry, Colleen K. Jackson-Cook, Debra E. Lyon, Kellie J. Archer

Biostatistics Publications

The pathological description of the stage of a tumor is an important clinical designation and is considered, like many other forms of biomedical data, an ordinal outcome. Currently, statistical methods for predicting an ordinal outcome using clinical, demographic, and high-dimensional correlated features are lacking. In this paper, we propose a method that fits an ordinal response model to predict an ordinal outcome for high-dimensional covariate spaces. Our method penalizes some covariates (high-throughput genomic features) without penalizing others (such as demographic and/or clinical covariates). We demonstrate the application of our method to predict the stage of breast cancer. In our model, …

Statistical Modeling Of Microrna Expression With Human Cancers, Ke-Sheng Wang, Yue Pan, Chun Xu Jan 2015

Statistical Modeling Of Microrna Expression With Human Cancers, Ke-Sheng Wang, Yue Pan, Chun Xu

Health & Biomedical Sciences Faculty Publications

MicroRNAs (miRNAs) are small non-coding RNAs (containing about 22 nucleotides) that regulate gene expression. MiRNAs are involved in many different biological processes such as cell proliferation, differentiation, apoptosis, fat metabolism, and human cancer genes; while miRNAs may function as candidates for diagnostic and prognostic biomarkers and predictors of drug response. This paper emphasizes the statistical methods in the analysis of the associations of miRNA gene expression with human cancers and related clinical phenotypes: 1) simple statistical methods include chi-square test, correlation analysis, t-test and one-way ANOVA; 2) regression models include linear and logistic regression; 3) survival analysis approaches such as …


Effects Of Cobalt On Dna Double Strand Break Repair-Deficient Cells, Sean Raph Ms Jan 2015

Effects Of Cobalt On Dna Double Strand Break Repair-Deficient Cells, Sean Raph Ms

All Student Scholarship

Epidemiology studies of human workers exposed to particulate cobalt have found increased incidence of lung cancer. A hallmark of lung cancer, chromosome instability(CIN) manifests as either numerical or structural abnormalities, which are thought to result from unrepaired or miss-repaired DNA double strand breaks, homologous recombination (HR) and non homologous end joining (NHEJ). Previous studies have shown that HR protects cells against metal induced CIN while NHEJ does not. We investigated whether this outcome occurs for cobalt.
