USF Tampa Graduate Theses and Dissertations

Our understanding of humoral immune response to human papillomavirus (HPV) infection has been mainly derived from studies in women. Very little is known about humoral immune response to HPV in men. There is also a growing interest in understanding the burden of HPV exposure in the subgroups of the male population, including men who have sex with women (MSW), men who have sex with men (MSM) and men who have sex with both men and women (MSMW). This dissertation was undertaken to understand and characterize humoral immune response, measured by detectable serum antibody IgG, to HPV 6, 11, 16 and …

Recent Diarrhea Is Associated With Elevated Salivary Igg Responses To Cryptosporidium In Residents Of An Eastern Massachusetts Community, A. I. Egorov, L. M. Montuori Trimble, L. Ascolillo, H. D. Ward, Deborah A. Levy, R. D. Morris, E. N. Naumova, J. K. Griffiths

Journal Articles: Epidemiology

BACKGROUND: Serological data suggest that Cryptosporidium infections are common but underreported. The invasiveness of blood sampling limits the application of serology in epidemiological surveillance. We pilot-tested a non-invasive salivary anti-Cryptosporidium antibody assay in a community survey involving children and adults.

MATERIALS AND METHODS: Families with children were recruited in a Massachusetts community in July; symptoms data were collected at 3 monthly follow-up mail surveys. One saliva sample per person (n = 349) was collected via mail, with the last survey in October. Samples were analyzed for IgG and IgA responses to a recombinant C. hominis gp15 sporozoite protein using a …

The Mediating Role Of Psychological Distress In The Relationship Between Adverse Childhood Experiences And Adult Smoking, Tara Wynn Strine

Walden Dissertations and Doctoral Studies

While research has indicated that impaired mental health partially mediates the relationship between adverse childhood experiences (ACEs) and alcohol and illicit drug use, little research has examined potential mediators in the relationship between ACEs and smoking, the number one cause of preventable mortality in the United States. Accordingly, this study examined the potential mediating effect of psychological distress on the relationship between ACES and smoking using data from Wave II of the ACE Study, a cross-sectional study completed between June and October of 1997 on a sample of adult health maintenance organization members (N = 7,211). The theoretical underpinnings for …

Immigration And Obesity In African American Adults Residing In The United States, Julius N. Ade

Walden Dissertations and Doctoral Studies

Obesity increases risk for heart disease, hypertension and other chronic diseases, and it affects minority ethnic groups disproportionately. However, it is unknown if African American immigrant adults, an increasing segment of the population, are at higher risk for obesity than African American non-immigrant adults residing in the United States. This study examined the association of obesity and immigrant status by comparing African American immigrant adults now residing in the United States to the general population of African American adults. The socio-ecological model provided the conceptual framework for this study. This study used a cross-sectional quantitative self-administered web-based survey to collect …

The Effect Of Direct Contact On Public Attitudes Towards People Living With Human Immunodeficiency Virus (Hiv) And Acquired Immune Deficiency Syndrome (Aids) In Zimbabweans, Mavis Mashingaidze

Walden Dissertations and Doctoral Studies

Stigma surrounding HIV and AIDS poses a significant threat to the curtailing of the epidemic by acting as a barrier to HIV testing and disclosure of serostatus. Previous research in the United States found personal knowledge of someone with HIV/AIDS to be a predictor of lower levels of HIV/AIDS-related stigma. However, no study to date has examined this relationship in Zimbabweans. Allport's contact hypothesis was hypothesis was the theoretical frame used to assess the effect of direct contact on public attitudes towards people living with the human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) in Zimbabweans with the …

Clinical Recognition Of Obstructive Sleep Apnea In A Population-Based Sample, Mark R. Zellmer

Walden Dissertations and Doctoral Studies

Obstructive sleep apnea (OSA), a disorder in which the airway intermittently collapses and obstructs during sleep, is associated with increased cardiovascular and cerebrovascular morbidity and mortality, increased risk of motor vehicle accidents, metabolic syndrome, hypertension, and depression. Treatment of OSA attenuates or reverses many of these associated risks. However, most cases of OSA are unrecognized and untreated. The two most recent studies using 1990s data found that only 6.5 - 15.4% of OSA cases, depending on severity, are clinically recognized in mixed gender populations. Based on a conceptual framework of improved physician awareness of OSA, and reduced diagnostic access bias …

Risk Factors For Development Of High Blood Pressure And Obesity Among African American Adolescents, Monique Shanta White

Walden Dissertations and Doctoral Studies

Childhood obesity has reached epidemic proportions in the United States and has been linked to hypertension, especially among African American youth. Optimistic bias leads youth to underestimate their susceptibility to negative health outcomes. Public health officials want to reduce risk factors to result in significant long term reduction in cardiovascular disease. The purpose of this study was to explore adolescent behavior practices in a school district and prevalence of high blood pressure and obesity in that population. The health belief model guided the framework for this study. Research questions examined relationship between individual health risk practices and optimistic bias on …

Racial /Ethnic Disparities In Hypertension In United States Residents: A Cross-Sectional Study Of Potential Explanatory Covariates, Franklin I. Opara

Walden Dissertations and Doctoral Studies

Racial/ethnic disparities persist in hypertension (HTN) prevalence in the United States, and African Americans are disproportionately affected. The incidence is more than two-folds in African Americans compared to Caucasians, and mortality is highest among African Americans. Understanding the risk factors in HTN and how these factors vary across racial/ethnic groups is essential to reducing the mortality among African Americans. This study examined the prevalence of HTN among a sample non-institutionalized U.S. residents (N = 30,852), assessed racial/ethnic disparities and determined factors associated with racial/ethnic variance in HTN. A cross-sectional design was used to address these aims, utilizing the National Health …

Observer-Dependent Model For Analyzing Subjective Parameters In Epidemiology, Milad Zarei

Open Access Theses & Dissertations

Although medical technologies for preventing the contagion and spread of infectious diseases have improved steadily throughout the last century, new infectious diseases are still emerging and spreading swiftly. The modeling of infectious disease spread is crucial in addressing the lack of predictive ability in epidemiology. Managing the spread of infectious diseases requires processing quantitative epidemiological data and the ability to capture the dynamics of the infectious disease in order to provide a measure of control.

In this thesis, I have introducing cognitive biases in diseases spread modeling. For the first time, to the author's knowledge, the human subjective experience has …

The Latina/O Mental Health Paradox Or Racial/Ethnic Disparities? Depression Among New Immigrants To The U.S, Sandra Iveth Ramirez

Open Access Theses & Dissertations

The Latino/a Mental Health Paradox states that the foreign-born immigrants have better mental health outcomes when compared with native-born groups of various ethno-racial backgrounds, with the gap in mental stress minimizing overtime. The objective of this study is to examine whether Latina/os immigrants suffer an ethno-racial disparity in mental health or if they have favorable mental health outcomes as predicted by the Paradox. Expanding on the Latina/o Mental Health Paradox, rather than comparing Latina/o immigrants with native-born, this study will compare depression among recently legalized Latina/os with recent legalized European immigrants.

The 2009 H1n1 Influenza A “Swine Flu” Virus Presentation In Virginia 2009, Tammie Smith

Theses and Dissertations

Objective: 2009 H1N1 influenza was first detected in the Northern Hemisphere in April 2009. National data have suggested that the novel influenza virus disproportionately causes severe illness in children and young adults, a somewhat different presentation from traditional seasonal flu which normally strikes hardest in the very young and older adults. This may or may not be the case in Virginia, which, if it is different, may suggest a need to alter flu prevention messages and vaccine policy as the outbreak continues through the fall 2009-10 influenza season. This report examined the early presentation of the new influenza virus in …

Causal Inference In Epidemiological Studies With Strong Confounding, Kelly L. Moore, Romain S. Neugebauer, Mark J. Van Der Laan, Ira B. Tager

U.C. Berkeley Division of Biostatistics Working Paper Series

One of the identifiabilty assumptions of causal effects defined by marginal structural model (MSM) parameters is the experimental treatment assignment (ETA) assumption. Practical violations of this assumption frequently occur in data analysis, when certain exposures are rarely observed within some strata of the population. The inverse probability of treatment weighted (IPTW) estimator is particularly sensitive to violations of this assumption, however, we demonstrate that this is a problem for all estimators of causal effects. This is due to the fact that the ETA assumption is about information (or lack thereof) in the data. A new class of causal models, causal …

What Factors Predict Outcome At Relapse After Previous Esophagectomy And Adjuvant Therapy In High-Risk Esophageal Cancer?, Edward Yu, Patricia Tai, Richard Malthaner, Larry Stitt, George Rodrigues, Rashid Dar, Brian Yaremko, Jawaid Younus, Michael Sanatani, Mark Vincent, Brian Dingle, Dalilah Fortin, Richard Inculet

Oncology Presentations

Management of patients who have disease relapse after completion of surgery and adjuvant chemo-radiation (CRT) is controversial.

Some oncologists would advocate intensive therapeutic intervention due to promising experience on treatment for recurrence disease while others would recommend palliative support due to the concerns for poor patient outcome post disease recurrence.

In Addition, it is not clear if patient outcome is improved post adjuvant CRT when patients at risk have resection margin involvement and if time interval to recurrence can affect patient survival post relapse.

The present study was conducted to determine what factors will affect patient outcome at relapse after …
