Spatial-Temporal Distribution Of Mosquito Larval Hot Spots In Papoli, Uganda: A Community-Based Approach To Mosquito Control, Ryan E. Tokarz

USF Tampa Graduate Theses and Dissertations

Mosquito species of the Anopheles gambaie complex are the predominant vectors of malaria transmission throughout sub-Saharan Africa. These mosquitoes tend to be endophilic, as well as anthropophilic, making them prime candidates for disease transmission. Within the same region, related mosquito vectors play a significant role in the transmission of additional human and zoonotic diseases. Furthermore, mosquito nuisance biting is an immense issue that cannot be ignored in terms of its impact on African communities. Depending on the respective factors involved, mosquito control programs throughout the continent have attempted to tackle these issues in a multitude of ways. This research approached …

Background: Over the last twenty years the incidence of herpes zoster (HZ) infection, also known as shingles, has been increasing among adults for unknown reasons. The economic burden of HZ is currently estimated at over $1 billion per year in the United States (U.S.) and is expected to increase as the susceptible adult population ages. HZ is caused by a re-activation of the varicella zoster virus (VZV), chicken pox, and more than 95% of adults living today carry the virus with a lifetime risk of 1 in 3 for developing HZ. In 2006 the FDA approved a vaccine for the …


Ambient Ozone And Cadmium As Risk Factors For Congenital Diaphragmatic Hernia, Rema Ramakrishnan Nov 2017

Ambient Ozone And Cadmium As Risk Factors For Congenital Diaphragmatic Hernia, Rema Ramakrishnan

USF Tampa Graduate Theses and Dissertations

Congenital diaphragmatic hernia (CDH) results from a defect in the diaphragm through which abdominal contents enter the thorax displacing the heart and the lungs. This causes lung hypoplasia and varying degrees of pulmonary hypertension resulting in high rates of morbidity and mortality. Though CDH has a prevalence rate of 2.61 per 10,000 live births it is an expensive birth defect with an estimated annual cost of nearly $250 million for all CDH survivors. Maternal exposure to air pollutants have not been studied as risk factors for CDH in humans. Ambient ozone has been found to be risk factors for certain …

Globally, there is still a large number of people without access to safe drinking water; a known health risk. In rural areas of countries like Peru, when potable water systems are built the responsibility for maintaining these systems is given to volunteer water committees. Despite its prevalence as a management model, there is a consensus that community management alone cannot ensure sustainable water service. Therefore, the overall goal of this research is to assess the sustainability of community-managed water systems in rural areas of the department of Amazonas, Peru. Specifically, this research examines two mechanisms that have been shown to …


Validation Of Chimeric Viruses In Plaque Reduction Neutralization Test In Arboviral Disease Diagnostics, Jasmine Boykin Oct 2017

Validation Of Chimeric Viruses In Plaque Reduction Neutralization Test In Arboviral Disease Diagnostics, Jasmine Boykin

USF Tampa Graduate Theses and Dissertations

The plaque reduction neutralization test (PRNT) is a confirmatory diagnostic assay that is used to confirm a variety of diseases. The performance of PRNT requires the use of infectious wild type viruses, which increases the risk of laboratory acquired infections. For instance, eastern equine encephalitis (EEEV) is a highly virulent pathogen used in PRNT that can result in potentially fatal neurological diseases among humans and equines. Therefore, arboviral PRNT must be performed in Biosafety Level 3 (BSL-3) containment facilities and may require select agent approved scientists, like in the case of EEEV. These stringent requirements restrict the ability of public …

The Effects Of Maternal Folate On Fetal Brain And Body Size Among Smoking Mothers, Korede K. Adegoke Jul 2017

The Effects Of Maternal Folate On Fetal Brain And Body Size Among Smoking Mothers, Korede K. Adegoke

USF Tampa Graduate Theses and Dissertations

The adverse effects of maternal smoking on infant mortality and morbidity has been well documented in the literature. Maternal tobacco use is causally associated with fetal growth restriction and correlates negatively with folate intake and metabolism. Studies have examined the association between smoking and folate levels during pregnancy, but very few have assessed this relationship using objective and accurate measures of both variables. Furthermore, despite evidence of a causal association between smoking in pregnancy and intrauterine growth restriction, and a plausible relationship between tobacco use and low maternal folate which is required for optimal fetal growth, no experimental study has …


Distribution Of Polybrominated Diphenyl Ethers Among Demographic Categories, Giorvanni Merilis Jul 2017

Distribution Of Polybrominated Diphenyl Ethers Among Demographic Categories, Giorvanni Merilis

USF Tampa Graduate Theses and Dissertations

Polybrominated Diphenyl Ethers (PBDEs) are flame retardants widely used within the United States in various products such as plastics, electronics, textiles and furniture. With an increase in production and usage, PBDEs have recently emerged as a contaminant of concern. Due to their chemical structure, PBDEs have the propensity to bioaccumulate in mammals. In fact, elevated PBDE concentrations have been recorded in human breast milk. Due to the potential widespread exposure to PBDEs, this study investigates human blood concentrations of PBDEs generated through the 2003-2004 National Health and Nutrition Examination Survey. Through the use of statistical modeling, a comparison of mean …


Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb Jul 2017

Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb

USF Tampa Graduate Theses and Dissertations

The spread of infectious diseases can be described in terms of three interrelated components: interaction, movement, and scale. Transmission between individuals requires some form of interaction, which is dependent on the pathogen, to occur. Diseases spread through the movement of their hosts; they spread across many spatial scales from local neighborhoods to countries, or temporal scales from days to years, or periodic intervals. Prior research into the spread of disease have examined diffusion processes retrospectively at regional or country levels, or developed differential equation or simulation models of the dynamics of disease transmission. While some of the more recent models …


Ability Of Physiological Strain Index To Discriminate Between Sustainable And Unsustainable Heat Stress, Dwayne Wilson Jun 2017

Ability Of Physiological Strain Index To Discriminate Between Sustainable And Unsustainable Heat Stress, Dwayne Wilson

USF Tampa Graduate Theses and Dissertations

Introduction: Assessment of heat strain is an alternative approach to assessing heat stress exposures. Two common measures of heat strain are body core temperature (TC) and heart rate (HR). In this study TC was assessed by rectal temperature (Tre). Physiological Strain Index (PSI) was developed to combine both Tre and HR into one metric. Data collected from progressive heat stress trials were used to (1) demonstrate that PSI can distinguish between Sustainable and Unsustainable heat stress; (2) suggest values for PSI that demonstrate a sustainable level of heat stress; and (3) determine if clothing or …

The Effect Of Antigen Polymorphisms On Serological Antibody Detection Assays Based Upon The, Kristi M. Miley

USF Tampa Graduate Theses and Dissertations

Onchocerca volvulus is a filarial parasite transmitted to humans by female Simulium spp. black flies. Infection with this parasite can cause blindness and severe skin disease among humans in Africa and the Americas. Enzyme-linked Immunosorbent Assay serological testing of OV-16 antigen is a diagnostic tool for determining effective elimination of the parasite. Programs typically rely on OV–16 ELISA to evaluate the progress towards interruption and/or elimination of disease by mass drug distribution of ivermectin and vector larvicidal control efforts. As elimination grows closer, monoclonal antibody positive controls for OV-16 ELISA become important to develop for Onchocerca testing due to the …

Influence Of Environmental Parameters On Mold Sampling Results, Benjamin Fishman Jun 2017

Influence Of Environmental Parameters On Mold Sampling Results, Benjamin Fishman

USF Tampa Graduate Theses and Dissertations

Mold is a type of fungus present in nearly all environments. Mold thrives under several environmental parameters such as high humidity and an adequate food source. A professional, such as an industrial hygienist, can measure mold in indoor and outdoor environments. Industrial hygienists commonly use a cascade impactor with a culture plate to capture air within a sampling area. While collecting air samples, environmental parameters such as temperature, humidity, and carbon dioxide are recorded. A laboratory then cultures and analyzes the samples, identifying the types and amounts of viable mold found in the sampling area.

In this study, a data …


Deployment, Post-Traumatic Stress Disorder And Hypertensive Disorders Of Pregnancy Among U.S. Active-Duty Military Women, Michelle C. Nash Jun 2017

Deployment, Post-Traumatic Stress Disorder And Hypertensive Disorders Of Pregnancy Among U.S. Active-Duty Military Women, Michelle C. Nash

USF Tampa Graduate Theses and Dissertations

Introduction. Today women comprise 15% of the U.S. active-duty military, but are often overlooked in research of the Armed Forces. While some of the challenges faced by women are similar to men, they encounter unique stressors related to childcare while deployed, sexual harassment and assault, and gynecological needs. Women are also more likely than men to develop post-traumatic stress disorder (PTSD). Both stress and PTSD have been linked to the development of chronic hypertension and some adverse birth outcomes. We hypothesized that post-9/11/2001 era military women who deployed or who had indicators of PTSD would be at greater risk of …

Poverty In The Land Of Plenty? Deconstructing Role Of Community-Based Organizations In A Small Community, John Kevin Trainor

USF Tampa Graduate Theses and Dissertations

Using the lens of a community-based childhood obesity intervention, it is possible to examine the role of non-profit organizations in community development and to deconstruct the “community” in community-based research and identify the many competing interests within a community. This contextual understanding includes how the community is formed, how a community’s agenda is set, and who will complete the tasks outlined in that agenda. In applied anthropological settings and public health interventions that are community-based, it is essential to understand the context of community and which community (or communities) the researcher is working with to ensure that the data you …


Back Muscle Endurance As Measure By Ito Test Duration, Ronald Figueredo Mar 2017

Back Muscle Endurance As Measure By Ito Test Duration, Ronald Figueredo

USF Tampa Graduate Theses and Dissertations

Lower back pain remains one of the most common problems in public health throughout the industrialized world (Strine and Hootman) (Shiri, Solovieva and K.). The prevalence is about 39-54% annually and 60-65% in a lifetime (Hillman, Wright and Rajaranam) (Leboeuf-Yde, N. and Lauritzen). In the United States, lower back pain is the second most common cause of disability, and is the highest cause of disability among men (Center for Disease Control, 2009). An individual quantitative physical examination to detect muscle deficiencies would be very useful for proper placement of workers in demanding physical jobs where back injuries are common. Trunk …
