Residency Education In Preparing Adolescent And Young Adults For Transition To Adult Care: A Mixed Methods Pilot Study, Janet S. Hess

USF Tampa Graduate Theses and Dissertations

Background: There is considerable evidence that physicians lack sufficient training in facilitating transition from pediatric to adult care systems for adolescents and young adults (A/YA). While several primary care residency programs have introduced health care transition (HCT) curricula in recent years, there are few studies that assess the effectiveness of HCT teaching models.

Purpose: To assess the impact of a residency education program that uses electronic health records (EHR) and other methods to teach residents how to prepare A/YA for transition to adult care.

Methods: In a mixed methods, quasi-experimental research design, quantitative methods were used to measure change in …

Structural Processes And Local Meaning: Explanatory Models, Political Economy, And Chagas Disease In Tropical Bolivia, Colin James Forsyth

USF Tampa Graduate Theses and Dissertations

This project describes and analyzes explanatory models of Chagas disease among people in a highly endemic area of eastern Bolivia, and examines the role that cultural and structural factors play in shaping explanatory models of this disease. Dressler (2001) characterizes medical anthropology as divided between two poles; the constructivist, which focuses on the "meaning and significance that events have for people," and the structuralist, which emphasizes the relationships between the components of a given society. This project endeavors to synthesize structuralist and constructivist perspectives by understanding the interaction between structural processes and explanatory models of Chagas disease.

The research took …

Not On My Street: Exploration Of Culture, Meaning And Perceptions Of Hiv Risk Among Middle Class African American Women, Corliss D. Heath

USF Tampa Graduate Theses and Dissertations

Black women remain at a higher risk for HIV infection than women of any other ethnic group. Of all new infections reported among U.S. women in 2010, 64% occurred in African Americans compared to 18% Whites and 15% Hispanic/Latina women (CDC 2013a; CDC 2014b). While the literature on HIV risk among African American women is extensive, it mostly focuses on low income, low education subgroups of women or those involved in high risk behaviors such as drug use. Very little has been done to understand the risk for HIV among college educated, middle class women who do not fit into …

Examination Of Possible Protective Effect Of Rhesus D Positive Blood Factor On Toxoplasma-Related Depressive Symptoms In Pregnancy, Lisa Lynn Parnell

USF Tampa Graduate Theses and Dissertations

Toxoplasma gondii infects approximately one third of the population worldwide. There is strong evidence that a relationship between T. gondii titer and depressive symptoms exists. There is also evidence suggesting a protective effect of RhD positive blood factor on toxoplasma-induced behavioral and personality changes. This protective effect may influence the relationship between T. gondii and prenatal depressive symptoms. The purpose of this secondary data analysis was to examine the possible protective effect of RhD positive blood factor on prenatal depressive symptoms in 56 pregnant women with T. gondii infection. The cross-sectional design was utilized to answer the question “Does positive …

Statistical Analysis And Modeling Of Pm2.5 Speciation Metals And Their Mixtures, Boubakari Ibrahimou

USF Tampa Graduate Theses and Dissertations

Exposure to fine particulate matter (PM_2.5) in the ambient air is associated with various health effects. There is increasing evidence which implicates the central role played by specific chemical components such as heavy metals of PM_2.5. Given the fact that humans are exposed to complex mixtures of environmental pollutants such as PM_2.5, research efforts are intensifying to study the mixtures composition and the emission sources of ambient PM, and the exposure-related health effects. Factor analysis as well source apportionment models are statistical tools potentially useful for characterizing mixtures in PM_2.5. However, classic …

USF Tampa Graduate Theses and Dissertations

The public use version of the National Comorbidity Survey - Replication (NCS-R) dataset was used (N = 995) to investigate risk factors for recurrent major depressive disorder (MDD) that are evident before recovery from the first major depressive episode (MDE) by comparing persons diagnosed with MDD who experienced a single MDE to persons with recurrent MDD.

Multiple logistic regression analyses assessed the independent risk of recurrent MDD for each of the following risk factors: an early age of onset (old), absence of a life stress trigger, chronic first episode, childhood parental loss, parental maltreatment, parental depression, comorbid anxiety disorder, and …

Penetration Through The Staple Punctures On Five N95 Respirator Models, Daniel E. Medina

USF Tampa Graduate Theses and Dissertations

Certain N95 FFR models that staple the head straps directly onto filtering material are commercially available. This method of assembly can tear or reduce fiber density in the immediate area surrounding the staple punctures. Five N95 FFR models were evaluated to determine if staple punctures on the filter medium reduce the protection offered by the respirators.

Total penetrations were measured with the staple punctures intact and when stretching the head straps a distance equivalent to a 95% male head circumference. Filter penetration were measured by sealing the staple punctures. Aerosols of 200, 500, and 1000 nm were used to challenge …

Medicaid Pays For That? An Exploratory, Mixed-Methods Analysis Of Florida Home Birth, Nicole K. Demetriou

USF Tampa Graduate Theses and Dissertations

The overwhelming social norm for pregnant women in the U.S. is to receive prenatal care from an obstetrician and to give birth in a hospital setting. However, the incidence of midwifery care and out-of-hospital birth is increasing, particularly among White, non-Hispanic women. Florida has been considered a "model" state for home birth midwifery given legislative support that mandates coverage of all types of midwifery (e.g., Certified Professional Midwives and Certified Nurse-Midwives) care in all birth settings (e.g., hospital, home, birth center) and by all forms of insurance (e.g., commercial and Medicaid). Medicaid is the payer source for nearly half of …

Applicator Exposure To Glycol Derivatives And Total Volatile Organic Compounds During The Application Of Spray Polyurethane Foam Insulation, Michael Brian Kaniuga

USF Tampa Graduate Theses and Dissertations

There is currently high demand for new building materials which are considered "environmentally friendly" or "green" for both new construction and renovations. Spray polyurethane foam (SPUF) insulation has gained significant acceptance by both consumers and the construction industry due to its high R-value, which results into significant energy savings among other things. Despite its acceptance by consumers and the construction industry, consideration must be given to potential chemical exposures to applicators installing these products.

This study sought to determine, through quantitative experimentation, if there was a release of glycol derivatives including, diethylene glycol (DEG), ethylene glycol (EG), and propylene glycol …

Characterization Of The Airborne Particulates Generated By A Spray Polyurethane Foam Insulation Kit, Loren Lee Foster

USF Tampa Graduate Theses and Dissertations

Spray Polyurethane Foam insulation (SPF) kits are currently being marketed and sold to do-it-yourselfers to meet various insulating needs. Like commercial SPF systems, the primary health concern with SPF kits is user overexposure to the isocyanates during product application. The potential health risk associated with SPF applications is driven by several factors including (but not limited to): the toxicity of isocyanates; the potentially high exposure intensity; the quantity of isocyanates used in the process; the enclosed nature of the environment in which the product could be applied; the potentially high exposure duration/frequency; and the limited availability of control measures to …

An Examination Of Coalition Functioning And Use Of Evidence-Based Practices: A Case Study Of Four Community Substance Abuse Coalitions, Nichole M. Snyder

USF Tampa Graduate Theses and Dissertations

There has been a recent expansion of community-based coalitions to address issues related to youth substance use. Research on their overall effectiveness, however, has produced mixed results. Recommendations to improve coalition success have emphasized the high-quality implementation of evidence-based programs targeting specific community needs. Coalitions vary extensively, however, in their organization and functioning. In addition, the lack of a universally accepted theoretical framework to understand coalition functioning has led to inconsistencies in the coalition research and the specific constructs used to describe coalition functioning.

Purpose of the Study: To address these gaps, the current study used a case study approach …

Substance Abuse Prevention In American Indian And Alaska Native Communities: Exploration Of Guiding Theoretical Underpinnings And Theoretical Fit In Practice, Margaret L. Walsh

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to identify ways Indigenous theoretical perspectives may guide current and future substance abuse prevention programs. As the majority of current theories guiding substance abuse prevention programs in American Indian and Alaska Native communities stem from Western ideologies and lack Indigenous perspectives, there is a paucity of research on theoretical underpinnings for Indigenous perspectives in AI/AN communities and their potential role in substance abuse prevention programming. It is well known that when programs are theoretically connected to the communities in which they are implemented, they are more likely to be accepted, accurately measured, and sustained …

Monitoring And Use Of Social Media In Emergncy Management In Florida, Leila Martini

USF Tampa Graduate Theses and Dissertations

To meet the rising food demands of communities in Accra,Ghana, urban agriculture has been popularized as a way to increase food security and improve nutrition (Donovan et al., 2012). Urban agriculture is defined as "the cultivation of crops at both the subsistence and commercial levels including the keeping of livestock in open spaces in urban areas (Adjaye, n.d.). In Accra, urban agriculture covers 1,091 hectares, employs over one thousand people, and supplies residents with 90% of its vegetables ("Accra Metropolitan", n.d.). Further, 60% of households in Accra participate in backyard farming ("Accra Metropolitan", n.d.). Although urban agriculture provides many benefits …

Perspectives Of Hiv + Women On The Mother To Child Transmission Of Hiv In Addis Ababa, Ethiopia, Kimberly Anne Fleek

USF Tampa Graduate Theses and Dissertations

Purpose and rationale: In 2012, an estimated 9,500 infants in Ethiopia were born with HIV. Mortality for these infants is high, and preventing infection offers the best hope for reducing the childhood death rates. Effective measures exist which can reduce the likelihood of a child acquiring HIV from its mother to less than 2%, and the necessary anti-retroviral medications are free and accessible to Ethiopian women. However, Prevention of Mother to Child Transmission of HIV (PMTCT) efforts in the country have not kept pace with the global reduction in infant infections over the last decade, and the Ethiopian MTCT rate …

"Wake Up The Knowledge That You Have": An Assessment Of Community Food Security In Fellsmere, Florida, Susan Marie Tyler

USF Tampa Graduate Theses and Dissertations

In the global industrial agricultural system many people lack access to high-quality nutritious foods and food production techniques are often inefficient and reliant on harsh chemical inputs. While numerous strategies exist to address the disparities present in the global food system, increasingly researchers and practitioners are looking to local food systems for solutions to strengthen community food security (CFS). CFS emphasizes small-scale production strategies such as farmer's markets, community gardens, and consumer supported agriculture. As these efforts evolve, research is needed to understand how these strategies affect communities. To explore a local CFS initiative, qualitative data were collected from community …

Development Of An Efficient Human Hepatocyte Culture Platform For Assessing Novel Therapeutic Efficacy Against Plasmodium Liver Parasites, Steven Patrick Maher

USF Tampa Graduate Theses and Dissertations

Malaria is a critical and global public health problem, affecting over 200 million people every year, resulting in over 500,000 deaths. A vaccine is not currently available and only one drug, primaquine, is effective against the dormant stages of Plasmodium vivax. Preclinical assessment of novel therapeutic drugs and vaccines is hampered by the lack of an in vitro liver model for P. falciparum and P. vivax. To provide a stable human hepatocyte-based culture platform for parasite development, we engineered a microfluidic bilayer device capable of both simple and complex culture methods, including perfusion and co-culture, to better understand the requirements …

Individual And Partner Characteristics Associated With Genital Herpes Disclosure And The Relationship Between Disclosure Outcomes, Rejection, And Future Intentions To Disclose, Jaime L. Myers

USF Tampa Graduate Theses and Dissertations

Background: Genital herpes is one of the most common sexually transmitted infections in the United States. As genital herpes is incurable and contagious, individuals with genital herpes face the decision to disclose their status to potential sexual partners with each new relationship formed. Such disclosure places individuals with genital herpes in a position to face rejection, which is commonly reported as one of the most concerning aspects of having genital herpes. The present study seeks to further understand the nature of genital herpes disclosure by addressing two core aims: 1) to understand determinants of and reasons for disclosure and non-disclosure …

Cancer And Infection, Kathleen Hope Plummer

USF Tampa Graduate Theses and Dissertations

E. coli is the most frequently isolated Gram negative pathogen from bacteremia in cancer patients and is repeatedly recovered from many other extraintestinal illnesses. These infections are commonly endogenous in nature and interfere with the treatment of cancer resulting in increased healthcare costs, morbidity, and mortality rates. Cancer and the treatments related to cancer cause alterations in the microbiome of the gut and other organs. Despite this point, there is a serious lack of knowledge about the genetic types of E. coli infecting cancer patients. This gap results in vague prevention strategies and limited treatment options for cancer patients. Multi …
