An Examination Of Diet, Acculturation And Risk Factors For Heart Disease Among Jamaican Immigrants, Carol Renee Oladele

USF Tampa Graduate Theses and Dissertations

Background: The South Florida region is home to over 85,000 Jamaican immigrants. Yet, little is known about the dietary intakes and predictors of risk of disease within this immigrant group. An assessment of dietary intakes and the development of dietary intake methodologies specific to the Jamaican population was important as it permitted accurate estimation of the nutrient intakes of this immigrant population whose dietary habits are not well documented. In addition, nothing is known about the prevalence of risk factors for heart disease or factors influencing risk factors among this immigrant group. The purpose of this study was to assess …

"Not If, But When": Sex, Risk, And Trust In Timing Gardasil Vaccine Decisions, An Exploratory Study Among Healthcare Providers And Middle-Class Parents In The U.S., Kathleen Marie Brelsford

USF Tampa Graduate Theses and Dissertations

This dissertation research explores how values regarding sexuality, morality, responsibility, protection, trust, and risk — expressed through parent, daughter, and healthcare provider relationships and interactions — inform parental decisions regarding the Gardasil® vaccine. In particular, the research examines the competing and conflicting meanings that parents and providers ascribe to vaccination and how actors position the vaccine within a wider set of negotiated, value–laden discourses. Because these narratives are situated within a larger structural field that shapes the landscape in which providers and parents interact, relevant historical and structural factors, including vaccine policy, cost, and compensation are discussed.

The study was conducted over a four-month period from May-August of 2011, and it was divided into two stages. The first stage of the project consisted of volunteer participation with dengue fever surveillance brigades in the three communities with the highest incidence of dengue fever during the beginning of 2011. This initial stage employed participant observation as its research method. The second stage was conducted in a different community within Tegucigalpa. The primary research methods employed during the second stage of the …

The Role Of Male Partners In Childbirth Decision Making: A Qualitative Exploration With First-Time Parenting Couples, Sharon Dejoy

USF Tampa Graduate Theses and Dissertations

Fathers' attendance at childbirth is almost universal in the United States, but few researchers have addressed the role that males play in childbirth decision making. The number of technological interventions available to birthing women is increasing, as is the utilization of those interventions. The degree to which women choose or agree to these interventions plays a major role in individual and societal health outcomes. Therefore, health care policy makers and educators must find ways to help childbearing couples navigate the complex maze of decisions related to childbirth. However, policies and programs to increase shared decision making may not function as …

The Holistic Complementary Structure Of Western Bio-Medicine And Traditional Healing And Achieving Complete Health, Candace Gail Oubre

USF Tampa Graduate Theses and Dissertations

Achieving complete health requires a deep understanding of complementary cultural competency sensitivity between physician and patient. This may include but is not limited to access to preventative health care resources, access to health educational resources and access to cultural healing resources, for example, shamans, Ayurvedic physicians, and herbal healers. Advocates of cultural competency emphasize great importance on knowledge of the patients' cultural background; however, the transcendence of this knowledge can be explained further through complementary cultural competency sensitivity. This is when the cultures of the physician and patient complement each other in terms of understanding what is in the patients' …

Characterization Of The Serologic Responses To Plasmodium Vivax Dbpii Variants Among Inhabitants Of Pursat Province, Cambodia, Samantha Jones Barnes

USF Tampa Graduate Theses and Dissertations

The Plasmodium vivax Duffy Binding Protein (DBP) is the ligand in the major pathway for P. vivax invasion of human reticulocytes, making it an appealing vaccine candidate. Region II of DBP (DBP-RII) is the minimal portion of the ligand that mediates recognition of the Duffy Antigen Receptor for Chemokines (DARC receptor) on the reticulocyte surface and constitutes the primary vaccine target. Analysis of natural variation in the coding sequences of DBP-RII revealed signature evidence for selective pressure driving variation in the residues of the putative receptor-binding site. We hypothesize that anti-DBP immunity in P. vivax infections is strain-specific and hindered …

Discovery Of A Functional Ecdysone Response Element In Brugia Malayi, Tracy Enright

USF Tampa Graduate Theses and Dissertations

The aim of this study was to determine whether functional ecdysone response elements (EcREs) exist within the genome of Brugia malayi, a parasitic nematode that causes lymphatic filariasis. The hypothesis that EcREs exist in B. malayi stemmed from previous demonstration of a functional ecdysone response system in B. malayi (Tzertzinis et al., 2010). Real-time PCR (qPCR) experiments were conducted to measure gene expression levels for twelve genes proximal to five putative EcREs in 20-OH ecdysone treated and untreated B. malayi embryos. Seven genes showed consistent upregulation with 20-OH ecdysone treatment. Each of the five putative EcREs had at least one …

Community-Based Coalitions: Influencing Policy & Practice, Florida Covering Kids & Families

Florida Covering Kids & Families

Simple approaches to outreach can increase enrollment in CHIP. The Robert Wood Johnson Foundation (2010) found community-based coalitions can be simple yet effective methods to communicate needed policy and practice changes to those “charged with implementing insurance coverage”. Community-based coalitions are able to bring to light enrollment and retention barriers increasing the awareness of stakeholders and hopefully, help to create effective solutions.

An Observation Of Immunological Effect, A Diet Enhanced With Spirulina And Treatment With Fractalkine In Models Of Parkinson's Disease, Mibel M. Pabón

USF Tampa Graduate Theses and Dissertations

In my dissertation research we used use human wild type α-synuclein gene expression using an adeno-associated viral vector (AAV9) that induced a slowly progressive loss of dopamine (DA) neurons in the Substantia nigra (SN) as one of our animal model of Parkinson’s disease (PD). It is our hypothesis that neuroinflammation predisposes the brain to susceptibility to neurodegenerative diseases. Thus we examined the progression of a PD lesion and examined the manipulations of the immune system to understand further the inflammatory role when we administered exogenous soluble fractalkine.

The specific etiology of neurodegeneration in PD is unknown, but the inflammatory mechanisms …

Contextualizing Hiv/Aids Prevention And Treatment Programs In Zanzibar, Tanzania, Naheed Ahmed

USF Tampa Graduate Theses and Dissertations

International aid organizations and wealthy nations have contributed billions to combat the spread and treatment of HIV/AIDS in sub-Saharan Africa; however, these programs have been critiqued for not addressing the socioeconomic and cultural context of the epidemic, instead relying upon generalized approaches. The prevalence rate in Zanzibar, Tanzania is low in the general population, but high among vulnerable segments of Zanzibari society, resulting in interventions focusing on particular groups (e.g. sex workers, drug users, and men who have sex with men). Through interviews with government agencies, non-profit organizations, medical professionals, vulnerable populations, and HIV/AIDS patients, this paper examines how local …

Validation Of The Usf Safe Exposure Time Equation For Heat Stress, Arden Bruce Andersen

USF Tampa Graduate Theses and Dissertations

Heat stress conditions are prevalent in the working environment around the world. Often they are not readily engineered out. Administrative controls and, in extreme/toxic environments, personal protective gear are the means available to protect workers. For every combination of metabolic work rate, clothing ensemble and environmental WBGT, there is a time of exposure threshold, beyond which the worker can no longer compensate for the heat stress, and signs and symptoms of heat strain appear. Increasingly, worker environments require specialty clothing either for worker protection or to maintain a clean/sanitary environment. Prior to the publication of the USF safe exposure time …

The Natural History Of Human Papillomavirus Related Condyloma In A Multinational Cohort Of Men, Gabriella Anic

USF Tampa Graduate Theses and Dissertations

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, but few studies have examined the progression from HPV infection to disease in men. Genital condyloma are the most common clinical manifestation of HPV infection. Though not associated with mortality, condyloma are a source of emotional distress, and treatment is often painful with a high recurrence rate. The aims of this study were to examine the distribution of HPV types present on the surface of condyloma, estimate the incidence of condyloma overall and after type-specific HPV infections, assess the sociodemographic and sexual behavior factors independently associated …

Drug Courts Work, But How? Preliminary Development Of A Measure To Assess Drug Court Structure And Processes, Blake Barrett

USF Tampa Graduate Theses and Dissertations

The high prevalence of substance use disorders is well-documented among criminal offenders. Drug courts are specialty judicial programs designed to: 1) improve public safety outcomes; 2) reduce criminal recidivism and substance abuse among offenders with substance use disorders; and 3) better utilize scarce criminal justice and treatment resources. Drug courts operate through partnerships between the criminal justice, behavioral health and public health systems. Offenders participate in an intensive regimen of substance abuse treatment and case management while under close judicial supervision. Drug courts' effectiveness in reducing criminal recidivism and drug use has been documented through numerous primary studies as well …

Navigating The Child Welfare System: An Exploratory Study Of Families' Experiences, Lianne Fuino Estefan

USF Tampa Graduate Theses and Dissertations

Growing up in a family environment that includes child maltreatment can result in an array of negative consequences for children, including health, behavioral, developmental, and social difficulties, and these consequences can persist over the lifetime. Families who have come to the attention of child welfare services for child maltreatment are at particularly high risk for experiencing multiple concurrent problems, including intimate partner violence, substance abuse, and mental health issues, as well as other family challenges. It is essential to intervene effectively with this population. However, there are few qualitative studies of parent experiences in the child welfare system through which …

A Pilot Study Of Small-Scale Variations In Outdoor Benzene Concentrations, Samantha Catherine Fridh

USF Tampa Graduate Theses and Dissertations

Benzene is an important toxic chemical in urban air and known human carcinogen released substantially by mobile sources. It's important to understand the spatial variation of benzene concentrations in order to understand exposures of susceptible sub-populations such as children and minority groups. Current monitoring networks use large and expensive air samplers that require electricity and restrict the location and number of samplers, not allowing for fine spatial resolution data.

The goals of this study are to develop and evaluate protocols for passive sampling and analysis of ambient benzene concentrations, and conduct a pilot study investigating small-scale variations over an area …

Apparent Total Evaporative Resistance Values From Human Trials Over A Range Of Heat Stress Levels, Brian Grace

USF Tampa Graduate Theses and Dissertations

Clothing can influence heat stress depending on the design and its ability to act as a barrier. The progressive heat stress protocol permitted the collection of data to empirically estimate the apparent total evaporative resistance (R_e,T,a). Five different clothing ensembles were evaluated, which included work clothes, cotton coveralls, and three limited-use protective clothing ensembles including a pthesis-barrier ensemble, (Tyvek^® 1424), water-barrier, vapor-permeable ensemble (NexGen^® LS 417), and a vapor-barrier ensemble (Tychem QC^®). The study design called for three metabolic level's: low, moderate, and high (L, M, & H) and three heat stages: compensable, transitional, …

Case-Control Study Of Sunlight Exposure And Cutaneous Human Papillomavirus Seroreactivity In Basal Cell And Squamous Cell Carcinomas Of The Skin, Michelle R. Iannacone

USF Tampa Graduate Theses and Dissertations

Non-melanoma skin cancer (NMSC), comprised of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), is the most common cancer in Caucasians. Ultraviolet radiation (UVR) exposure is the most important environmental risk factor for both BCC and SCC development. However, the precise relationship between UVR and the risk of NMSC is complex, and the relationship may differ by skin cancer type. It has been hypothesized that intermittent patterns and childhood sunlight exposure are important for BCC while continuous (chronic) and lifelong (i.e. childhood and adulthood) sunlight exposure is important for SCC. Epidemiologic studies have demonstrated that cutaneous human papillomavirus (HPV) …

An Evaluation Of The Early Steps Referral Process In Hillsborough County To Detect Delays In Access To Early Intervention Services, Jessica Fry Johnson

USF Tampa Graduate Theses and Dissertations

Early intervention services are important in obtaining better outcomes for infants with a developmental delay or a condition that may result in a delay. In Florida, a primary resource for providing these services is the Early Steps Program. This study analyzed the Early Steps referral process to identify barriers to prompt access. The guiding hypothesis was if differences exist in key outcomes of the referral process, then these differences may reveal where improvements can be made. Improving access to early intervention should produce better outcomes and reduce the costs of services required later by addressing developmental concerns earlier.

The dataset …

Assessing The Relationship Of Monocytes With Primary And Secondary Dengue Infection Among Hospitalized Dengue Patients In Malaysia, 2010: A Cross-Sectional Study, Benjamin Glenn Klekamp

USF Tampa Graduate Theses and Dissertations

Dengue, a group of four similar viruses transmitted through the bite of a mosquito, is estimated to infect upwards of 100 million annually in over 100 nations throughout the global equatorial belt. Distribution of global dengue is highly skewed as Southeast Asian and Western Pacific regions endure 75% of the global dengue burden. Similar to other regional countries, Malaysia has been rapidly urbanizing, which has supported a hyperendemic dengue state.

The biological pathway by which dengue infection causes a wide range of clinical manifestations, spanning asymptomatic to life-threatening severe complications, is not comprehensively understood. Historically, severe dengue complications have primarily …

Three research questions were developed with statistical testing for gender differences based on similar cancer type, stage, treatment assignment and survival. Data for 44,863 primary lung cancer cases were collected from eight U.S. state-based cancer registries to investigate the research questions. The lung cancer incidence data included the morphological cell-types of adenocarcinoma (AC); squamous cell carcinoma (SCC); large cell carcinoma (LCC) and small cell carcinoma (SCC). Stage, grade, treatment type, as well as, …

Performance Assessment Of Predicted Heat Strain In High Heat Stress, Ronald Eugene Long

USF Tampa Graduate Theses and Dissertations

Heat stress is a common physical agent associated with many occupations. The most commonly used method of assessing heat stress exposure is an empirical method using the Wet Bulb Globe Temperature Index but his method is limited in its ability to parse out individual contributors to the heat stress. The International Organization for Standardization (ISO) published a rational model called Predicted Heat Strain (PHS) in 2004, and rational methods have the advantage of separating out the individual pathways for heat exchange. The objective of this research was a performance assessment of the current PHS model. This experimental design consisted of …

Numeracy, Cancer Risk Perceptions, And Self-Protective Behaviors Among U.S. Adults, Teri Malo

USF Tampa Graduate Theses and Dissertations

Individuals have become more involved in health-related decisions, in part due to an unprecedented access to information that can be used to enhance both physical and mental health. Much of this health-related information is presented in a numerical format; unfortunately, research suggests many Americans may not possess the literacy skills necessary to comprehend numerical health-related information. More research needs to be conducted to examine numeracy and its role in cancer risk perceptions, and how those risk perceptions relate to cancer self-protective behaviors. The purpose of the current study was to: (a) examine socio-demographic variables associated with numeracy, (b) determine which …

USF Tampa Graduate Theses and Dissertations

Background: The etiology of congenital heart valve defects is not well understood; little is known about the risk factors that contribute to the survival and mortality outcomes of children with these defects.

Methods: Using data from the Texas Birth Defects Registry (TBDR) we conducted a retrospective cohort study of 2070 singleton infants with congenital aortic, pulmonary, or tricuspid valve atresia or stenosis born in Texas between January 1, 1996 and December 31, 2007 to Hispanic, Non-Hispanic (NH) black, and NH white women. TBDR data were death-to-birth matched by the Texas Vital Statistics Unit for deaths between January 1, 1996 and …

Adolescence Is An Ocean: A Biocultural Investigation Of Youth Food Consumption In Tanzania, Elizabeth J. Danforth

USF Tampa Graduate Theses and Dissertations

This study investigates adolescents' relationships with food and other community and household members' perceptions of youth and their food consumption to understand the multifactorial dynamic processes which create nutritional outcomes among urban and rural youth in central Tanzania. Youth are an important and demographically large population in developing countries. The identities created during this distinct stage of cultural production can be reflected in youths' food consumption and relationships with food. Nutrition likely affects how youth transition through a variety of states, including their growth and development stages, primary to secondary to higher education, child to parent, or unemployed to employed. …

Apparent Total Evaporative Resistance Values From Human Trials Over A Range Of Metabolic And Heat Stress Levels, Matthew David Dooris

USF Tampa Graduate Theses and Dissertations

Failure to maintain thermal equilibrium can cause uncontrollable increases in body core temperature beyond critical upper limits. In selecting clothing, consideration must be given to the heat transfer properties of clothing that may restrict the cooling capacity of the human body under heat stress conditions, most importantly, apparent total evaporative resistance (R_e,T,_a). This study calculated and compared R_e,T,_a for five clothing ensembles under varying heat stress conditions, including three relative humidity (RH) levels and three stages of heat stress to determine if R_e,T,_a values varied or remained the same with …
