Mapping Nevada's Dental Workforce, Kelvin Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Access to care is a concern at the forefront of public health. Due to socioeconomic and geopolitical pressures, the distribution of healthcare providers across a population often does not coincide with the demand for healthcare in a specific geographic area. Rural areas typically do not have enough providers and urban areas typically have too many. This stark reality underscores an inherent inefficiency in the allocation of healthcare resources and is a discrepancy that must be addressed by state-sponsored institutions and programs. From a public health perspective, the problem of insufficient or lack of access to care is the greater of …

Applied Methodologies Demonstrated Through Three Independent Studies For Assessing The Effects Of Socioeconomic, Environmental Chemical Exposure, And Therapeutic Factors On Oncological Diseases And Covid-19, Bayarmagnai Maggie Munkhjargal

Legacy Theses & Dissertations (2009 - 2024)

When trying to understand risk factors for a disease, even before we know the causal agents, it is necessary to create a surveillance data set that answers the questions of who, when, and where, and includes any potential covariates which may either promote or prevent the disease. There are a wide variety of surveillance data. For example, hospital discharge data, such as the New York Statewide Planning and Research Cooperative System (SPARCS) data, encompass all hospitalized cases in the state, while clinical datasets cover a specially constructed population in pursuit of research of a certain disease type. Analysis of surveillance …

Plasma Proteins That May Cause Parkinson’S Disease And Multiple Sclerosis: A Mendelian Randomization Study, Brigid A. Staley

Dissertations and Theses

Multiple sclerosis (MS) and Parkinson’s disease (PD) are progressively disabling neurologic disorders that profoundly affect quality of life and shorten life expectancy. There is no cure for either disease, and current treatments only alleviate symptoms and may cause serious side effects. The causes of MS and PD are not well understood. Previous epidemiologic studies have documented numerous environmental risk factors for both diseases. However, these studies are inherently prone to bias from confounding which may generate spurious results. The lack of unbiased evidence on environmental causes of MS and PD has been a critical barrier to fully understanding their pathophysiology. …

Epidemiology Of Upper Urinary Tract Stones And Stone Management In Autosomal Dominant Polycystic Kidney Disease, Vinusha Kalatharan

Electronic Thesis and Dissertation Repository

Upper urinary tract stones are a major determinant of pain and is suggested to accelerate disease progression in patients with autosomal dominant polycystic kidney disease (ADPKD). For these reasons, stones should be optimally managed in patients with ADPKD. However, the kidney distortions may make managing stones challenging in patients with ADPKD. Understanding of the epidemiology of upper urinary tract stones and stone intervention and the outcomes of stone interventions is limited. The aim of this thesis is to understand the epidemiology of upper urinary tract stones and stone interventions and consequences of stone management in patients with ADPKD.

Is Vaping Related To Other Health Risk Behaviors Among Adolescents?, Alvina Emran

Senior Theses

Vaping (smoking a vaporized liquid with an active ingredient) has had an upward trend in high school populations (ages 13-18) within the last decade, mainly due to misinformation and targeting from companies that sell e-cigarettes (142, 7). The most common substances that are vaped in teens are nicotine and tetrahydrocannabinol (THC, the active ingredient in marijuana) (147). Nicotine and THC bind to NAchR and CB1 receptors that affect certain parts of the dopamine reward pathway, such as the prefrontal cortex, the ventral tegmental area, and the ventral striatum in the brain (44,106). Dysfunction within these pathways have been associated with …

Vaccine Confidence, Coverage, And Hesitancy Worldwide: A Literature Analysis Of Vaccine Hesitancy And Potential Causes Worldwide, Jordan Hammond

Senior Theses

Vaccines are one of the world’s most impactful medical therapies. They are cost-effective, successfully proven, and one of the quickest treatment options available today (Clark et al., 2016). They save millions of lives every year and have eliminated certain diseases on a national and international level. However, millions of people worldwide still remain unvaccinated. In developed nations, mainly The United States (U.S.) and the European countries, many of the unvaccinated are a result of rising vaccine hesitancy of parents in conjunction with the anti-vaccination movement. Vaccine hesitancy is defined as “a delay in acceptance or refusal of vaccines despite availability” …

On The Dynamics And Structure Of Multiple Strain Epidemic Models And Genotype Networks, Blake Joseph Mitchell Williams

Graduate College Dissertations and Theses

Mathematical disease modeling has long operated under the assumption that any one infectious disease is caused by one transmissible pathogen. This paradigm has been useful in simplifying the biological reality of epidemics and has allowed the modeling community to focus on the complexity of other factors such as contact structure and interventions. However, there is an increasing amount of evidence that the strain diversity of pathogens, and their interplay with the host immune system, can play a large role in shaping the dynamics of epidemics.

This body of work first explores the role of strain-transcending immunity in mathematical disease models, …

Predictive Modeling Of Influenza In New England Using A Recurrent Deep Neural Network, Alfred Amendolara

USF Tampa Graduate Theses and Dissertations

The disease of malaria is complex, with clinical presentation that ranges from severe and complicated to mild and uncomplicated or even to asymptomatic malaria. A recent effort made by several world organizations has shown important advances in the effort to control and eradicate malaria. Following the general ordinance established by the trans-border organizations, each country has tried to define, according to their local geopolitical scenario, individual ¨road maps¨ to succeed in reducing the morbidity and mortality caused by malaria. Moreover, it is now accepted universally that these road maps need to be revised and appropriated in order to correct actions …

Gestational Weight Gain, Offspring Asthma And Wheeze Phenotypes In Project Viva, Kathryn Wagner

Masters Theses

In the US, 8.4% of children are diagnosed with asthma by age 18, making asthma one of the most common chronic conditions among children. Additionally, 25% of children experience persistent wheezing by age 6, an indicator of childhood asthma. Both childhood asthma and persistent wheezing may be linked to inflammatory and immune mechanisms, which are associated with inadequate and excessive gestational weight gain. Studies investigating the relationship between gestational weight gain and offspring asthma and wheeze phenotypes are limited by self-reported gestational weight gain, early age at asthma and wheeze assessments, limited adjustment for potential confounders and no trimester-specific evaluations. …

Patient Sex And Physician Adherence To Treatment Guidelines For Non-Purulent Cellulitis, Rebecca Goldberg

Masters Theses

In 2015, participating US Emergency Departments (EDs) reported approximately 2.8 million visits related to skin and soft tissue infections (SSTIs). Studies indicate that there may be disparities by patient sex in physician treatment guideline adherence rates as a result of a gender bias during physician-patient interactions; however, only two epidemiologic studies have investigated the role of patient sex in guideline adherence rates for SSTIs. These prior studies were limited in size and covariate assessment. Thus, the magnitude and direction of the effect of patient sex is uncertain, warranting further research. Therefore, we conducted a large prospective study to elucidate the …

Evolutionary Dynamics Of Influenza Type B In The Presence Of Vaccination: An Ecological Study, Lindsey J. Fiedler

USF Tampa Graduate Theses and Dissertations

Understanding the evolutionary dynamics of influenza type B in human hosts is a public health concern as we strive to minimize the disease burden in seasonal epidemics. Vaccination is considered the best defense against contracting influenza, and everyone over the age of 6 months is advised to get vaccinated before each season. The effect that vaccine-acquired immunity has on the evolution of influenza B remains unclear. In the U.S., vaccine-uptake is irregular across the states, and the differing coverages present an opportunity to study how vaccination influences viral evolution. This thesis analyzes the evolutionary patterns of influenza B in the …

Public Health Policy: An Ethical Analysis Of Quarantine, Dina Alqahtani

Electronic Theses and Dissertations

As a public health measure quarantine has both historical and contemporary significance both in the United States and abroad. On the surface it represents a low-cost, low-tech way in which the spread of disease can be mitigated as its core requirement is that those who may have been exposed to an infectious agent are kept away from those who have not been exposed to that agent for enough time to determine whether or not infection has been spread. This has been utilized for centuries with both limited questions and scattered, inconsistent, or impossible to achieve oversight and goals. In understanding …

Respiratory Infections And Risk For Development Of Narcolepsy: Analysis Of The Truven Health Marketscan Database (2008 To 2010) With Additional Assessment Of Incidence And Prevalence, Darren Scheer

USF Tampa Graduate Theses and Dissertations

Background and Significance: Narcolepsy is a chronic neurological disorder. These patients experience various psychiatric and physical comorbid diseases and mortality at an increased rate compared to the general population. Additionally, patients with narcolepsy experience approximately a doubling of various annual healthcare related facility visits, transactions, and costs comparatively. Narcolepsy with cataplexy is generally believed to be more prevalent than narcolepsy without cataplexy. However, incidence and prevalence estimates of narcolepsy (with or without cataplexy) vary widely with few large epidemiological studies conducted worldwide and none in the U.S evaluating these proportions in both children and adults utilizing a large health care …

A Conflictive Triuvirate Consruct Of Epidemiologic Systems Failure, Ngozi Lois Ulinwa

Walden Dissertations and Doctoral Studies

Epidemiologic systems failure (ESF) is a major hurdle in minimizing the spread of infectious diseases during outbreaks. The reasons for ESF include the technical limitation of personnel handling epidemic crises, strictly defined health policies that limit the actions of epidemiologists, and personal perspective's reservations towards the intentions of health agencies. The purpose of this triumvirate mixed-methods case study was to examine factors of infectious disease control mechanisms useful for determining ESF. Three juxtaposed pre-emptive factors (technical [T], organizational [O], and personal [P] perspectives were used to determine how the multiple perspectives inquiring systems and fuzzy logic revealed factors causing ESF …
