Background: In the United States, it is estimated that there are more than 2 million cases of Hepatitis C (HCV), with over 66,000 new cases since 2020 However, an estimated 75% of those with HCV go undiagnosed and less than 35% receive treatment within a year of diagnosis. In 2018, UK Healthcare (UKHC) implemented a universal HCV screening method using a Best Practice Advisory (BPA) for anyone 18 and older who presented to the Emergency Department and had labs ordered. Patients who screened positive were then referred to outpatient clinics for HCV treatment. Approximately ten percent of positive patients …

Association Of Birth Weight And Preterm Birth With Subsequent Risk For Hypertension In Women From The Women’S Health Initiative, Christian P. Daniele

Masters Theses

Hypertension is a chronic disease with an estimated prevalence of nearly 50% in US adults. In addition to sociodemographic and lifestyle factors, evidence suggests that in utero and early life exposures may contribute to life-long risk of hypertension. This study aimed to investigate the potential associations between an individual’s birthweight and preterm birth status with their risk for hypertension in the Women’s Health Initiative (WHI) cohort. WHI is a large, multi-racial cohort of postmenopausal women. At study entry, birthweight and preterm birth status were self-reported by category (< 6 lbs., 6-7 lbs. 15 oz., 8-9 lbs. 15 oz., or ≥ 10 lbs.; ≥ 4 weeks premature or full term). Baseline and incident hypertension status were self-reported; mean systolic blood pressure, diastolic blood pressure, and 30-second pulse were also recorded at baseline by trained study staff. Linear, logistic, and Cox-proportional hazards regression models were used to generate crude and adjusted beta estimates, odds ratios, and hazards ratios, respectively. After adjusting for demographic and lifestyle factors, we found that participants born at a low birthweight had a higher mean systolic blood pressure than participants born at a normal birthweight and were at increased risk for both baseline and incident hypertension. Women born at a higher birthweight had a lower mean systolic blood pressure and were at lower risk for baseline and incident hypertension. When compared to participants born full term, participants born preterm were at increased risk for baseline and incident hypertension. These results support current research on early life exposures and health risks later in life. Long term follow-up or targeted counseling may be required for individuals born prematurely or at low birthweights to prevent and treat hypertension and associated cardiovascular outcomes.

Investigation Of Orthohantavirus Genetics In Rodent Reservoirs And Clinical Samples, Samuel M Goodfellow

Biomedical Sciences ETDs

Orthohantaviruses are negative-sense, single stranded RNA viruses with trisegmented genomes that can cause severe disease in humans and are carried by several host reservoirs throughout the world. In the United States, Sin Nombre orthohantavirus (SNV) is the primary cause of hantavirus cardiopulmonary syndrome (HCPS) with a fatality rate of ~36% and the highest cases occuring in the southwest region. The primary SNV host reservoir is thought to be the western deer mouse, Peromyscus maniculatus, however it has been shown that other rodents can carry different orthohantaviruses. We designed a pan-orthohantavirus detection tool to survey several small mammal populations throughout New …

Clinical And Environmental Factors Affecting The Survival Outcomes Among Stage 1a Tn0m0 First Primary Non-Small Cell Lung Carcinoma Patients In The United States., Naiya Patel

Electronic Theses and Dissertations

Background: Lung cancer is the second leading cause of death in the United States (U.S.). The most prevalent histological type of lung cancer is Non-Small Cell Lung Cancer (NSCLC), which has an overall five years survival of 5% if left untreated. Therefore, early treatment of NSCLC is vital to improve overall survival (OS) outcomes. Several factors affect survival outcomes, which can be categorized as modifiable or non-modifiable. The difference in timely receipt of guideline-concordant treatment affects the survival outcomes of patients with stage 1A NSCLC. This dissertation explored factors that affect treatment and survival outcomes among stage 1A NSCLC patients …

Obesity Risk And Comorbidities Among Colombians In New York City And In Colombia, Carlos A. Devia

Dissertations and Theses

Introduction: The prevalence of obesity and overweight in adults and children continues to increase worldwide, accounting for the mortality and morbidity from several diseases. Obesity disproportionally impacts Latinos in the United States (U.S.), and despite their diversity in origins, ancestry, and culture, it is still unclear the burden of obesity by specific Latino groups. For example, little information is available about how obesity impacts Colombians in the U.S. (the largest South American population). New evidence also indicates that Latino immigrants may no longer be arriving with healthy weight status to the U.S. because Latin American countries are undergoing epidemiologic and …

How Environmental Change Will Impact Mosquito-Borne Diseases, Arsal Khan

Master's Projects and Capstones

Mosquitos, the most lethal species throughout human history, are the most prevalent source of vector-borne diseases and therefore a major global health burden. Mosquito-borne disease incidence is expected to shift with environmental change. These changes can be predicted using species distribution models. With the wide variety of methods used for models, consensus for improving accuracy and comparability is needed. A comparative analysis of three recent modeling approaches revealed that integrating modeling techniques compensates for trade-offs associated with a singular approach. An area that represents a critical gap in our ability to predict mosquito behavior in response to changing climate factors, …

Eat Well, Be Well: Basic Needs Initiative's Online Hub For Nutrition Education, Misha Moseley

Capstone Projects and Master's Theses

Basic Needs Initiative at California State University, Monterey Bay is a department that provides students with food, housing, and wellness resources. Over half of the university's students experience food insecurity, and over 85% use non-academic resources to learn about nutrition. This project adds a dietary health section to the department’s website to increase students’ access to nutrition education. It addresses the micro-level agency problem that too few students eat a healthy, balanced diet. Unhealthy eating is a risk factor for food insecurity, so the project indirectly addresses the macro-level health problem that too many college students in California experience food …

An Ecological Study Of Glyphosate Use And Non-Hodgkin’S Lymphoma, Dexter Corlett, Steven R. Browning

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Glyphosate is currently the most widely used herbicide in the world. Initially thought to be non-carcinogenic in humans, in 2015 glyphosate was classified as a “probable carcinogen” by the International Agency for Research on Cancer due to several small epidemiological studies indicating a link between the pesticide and hematologic cancers, especially non-Hodgkin’s lymphoma (NHL). The current work is an ecological study using counties in Kentucky, Arkansas, and Iowa to compare glyphosate usage to NHL incidence using a multivariate Poisson regression. We found no significant correlation between glyphosate use and NHL incidence, though caution should be taken to draw significance from …

An Epidemiologic Study Of Vaccination Exemptions And Pertussis Risk, Corinne B. Tandy

Doctoral Dissertations

The incidence of pertussis, a vaccine-preventable disease that can have severe complications in infants, has been increasing in the United States over the past three decades. Vaccine hesitancy and refusal have also increased and are associated with vaccination exemptions, which in turn are associated with outbreaks of vaccine-preventable diseases, including pertussis. Understanding attitudes towards vaccinations and identifying geographic disparities of vaccination exemptions and pertussis risks is useful for guiding control programs. Therefore, the objectives of this study were to: (i) investigate attitudes towards vaccinations; (ii) identify county-level geographic disparities and sociodemographic predictors of vaccination exemptions in Florida; (iii) investigate county-level …

Ecology Of Hantaviruses In Rodent Reservoirs And Their Early Innate Immune Responses In Human Model Systems, Evan Peter Williams

Theses and Dissertations (ETD)

The spillover of zoonotic RNA viruses is responsible for a great deal of the disease outbreaks in human populations. These spillover events are set to continue due to anthropogenic and environmental changes that impact the distribution of these viruses. The viruses in the family Hantaviridae are classified as one of these emerging zoonotic RNA viruses. The spillover of the viruses in this family are responsible for two severe human diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). These viruses are distributed across the globe and are responsible for a large number of human disease cases with …

Incidence Of Cancer And Stage At Diagnosis Among People With Recent-Onset Psychotic Disorders, Jared C. Wootten

Electronic Thesis and Dissertation Repository

Evidence on cancer incidence in people with psychotic disorders, compared to the general population, is equivocal, although those with psychotic disorders so have more advanced stage of cancer at the time of diagnosis. The objective of this thesis was to compare cancer incidence and stage at diagnosis for people with psychotic disorders, relative to the general population. Our systematic review did not observe a significant difference in overall cancer incidence among people diagnosed with psychotic disorders (RR = 1.08, 95% CI: 1.00 to 1.16), however people with psychotic disorders were more likely to be present with advanced stage cancer at …

Birthweight And Risk Of Autoimmune And Thyroid Conditions Within The Women’S Health Initiative, Brian C. Monahan

Masters Theses

Autoimmune and thyroid conditions account for a substantial proportion of the morbidity and mortality experienced in the United States, affecting >40 million Americans combined. Co-occurrence of both an autoimmune and thyroid condition is also likely, particularly among women. Epidemiologic studies on both sets of conditions have examined many risk factors, including demographic, lifestyle, genetic, and environmental risk factors. However, one area which has been neglected is the effect of early life exposures on the development of autoimmune and thyroid conditions. To investigate the potential association between an individual’s birth weight (by category;in uteroand early childhood, extending the hypothesis to include …
