Occupational Exposures Associated With Thyroid Cancer In The Thyroid Tumor And Cancer Collaborative Registry In The Integrated Cancer Center Repository For Cancer Research, James Buckley

Capstone Experience

Thyroid cancer is one of the fastest growing cancers in the United States, with the rate of new cases increasing from 5.2 per 100,000 in 1985 to 13.8 per 100,000 in 2019, with a peak of 14.5 per 100,000 in 2015. Increased thyroid cancer incidence is associated with certain occupations, including healthcare and agriculture. Most existing literature on occupational exposures and thyroid cancer evaluate their association in terms of occupation type and thyroid cancer, rather than specific occupational exposures and thyroid cancer. This study sought to utilize the wide range of occupational exposure data in the Integrated Cancer Center Repository …

Program Evaluation: Utilizing Health Department’S Community Health Needs Assessment Data To Improve Emergency Preparedness Plans, Kathleen Gottschalk

Public health officials conducting emergency response plans must know how to easily identify the vulnerable populations in their community or jurisdiction. It is beneficial for access and functional needs appendices to include information and resources directed at the identified vulnerable groups before an emergency event to improve health outcomes. Community Health Needs Assessments (CHNA) can provide population-level statistics and information needed to easily identify vulnerable or at-risk groups. This report aims to evaluate the use of the CHNA data to guide the development of inclusive emergency response plans that account for vulnerable populations in local health department jurisdictions. The 2021 …

Environmental Exposures And Human Health Challenges: Evidence-Based Insights From Health Surveillance Systems, Jagadeesh Puvvula

Theses & Dissertations

Human exposure to environmental hazards is associated with a variety of preventable adverse health outcomes. As the environmental health risks result from the complex interaction between hazard, exposure, and susceptibility, these exposure-outcome associations are heterogeneous across the population. Improving environmental health literacy by advocating evidence-based environmental risk communication could play a role in reinforcing protective behavior against environmental hazards. The use of public health surveillance systems to assess the exposure-response associations is one of the effective ways to quantify the environmental health risks. However, there are several gaps in effectively quantifying environmental health risks. This dissertation aims to address a …

A Systematic Literature Review Of The Prevalence, Distribution, Exposure, And Human Health Risks Of Tire Microplastics And The Contribution Of Their Physicochemically Diverse Properties, Luke Glastad

Theses & Dissertations

The history of synthetic plastics dates back to their first uses in 1907, continues with their expansion through the middle of the century with a diverse array of new polymers, and are so omnipresent today that many label this age of Earth the Plasticene Era. Tire microplastics (TMPs) have been increasingly identified as one of the environment's most bountiful types of microplastics (MPs). TMPs mainly enter the environment as tire-wear particles (TWPs) and recycled tire crumb (RTC). TWPs, in particular, have a high degree of variability, which impacts their distribution, degradation, and risk for adverse human health effects. This review …

Development Of A Web-Based Agriculture Health Risk Assessment Tool For Military Veteran Farmers And Ranchers, Alyssa Damke

Capstone Experience

In the U.S., significant health disparities exist among rural populations compared to their urban counterparts. These disparities can be compounded in agricultural workers due to the dangerous and unpredictable nature of their work. Agricultural producers who are also military Veterans may experience additional health pressures that are often overlooked in the healthcare setting. Over 2.5 million Veteran Health Administration (VHA) patients reside in rural areas and the healthcare infrastructure to care for these Veterans may not include an agricultural occupational approach. To address healthcare disparities in Veteran farmers and ranchers, this study, in collaboration with AgriSafe Network, will be used …

Developing A Rabies Prevention Program Based On Rabies Exposure Data In Nebraska, Jill Oatman

Capstone Experience

Eighty-nine percent of Nebraska’s towns are considered rural, with populations of less than 3,000 people and with many towns having less than 1,000 residents. Rural areas consist of crop ground, livestock facilities and regions inhabited by wildlife. Nebraska has two large urban cities, Lincoln and Omaha. Animal and human health in these communities can be greatly impacted by infectious diseases that are transmitted between animals and humans, known as zoonotic diseases. One zoonotic disease of great concern is rabies. Zoonotic diseases not only impact the health of animals and humans, but the social well-being of communities and result in increased …

Evaluation Of Relationship Between Lead-Dust Loading, Lead-Dust Concentration, And Total Dust Loading Metrics Across Multiple Data Sets, Charles Bevington

Capstone Experience

Lead-dust monitoring studies report values as either lead-dust loadings µg/ft² or as lead-dust concentrations µg/g. It is rare for studies to report both metrics. When only lead-dust loading values are present, professionals require an approach to estimate lead-dust concentration values. A literature search identified five studies that contained raw data for both lead-dust loading and lead-dust concentration. An additional thirty-two studies had summary-statistics available for both lead-dust loading and lead-dust concentration. Studies with raw-data were used to develop an empirically-based loading to concentration statistical relationship. Raw data sets were critically evaluated to determine whether elimination or …

Epigenetic Modifications Of Human Placenta Associated With Preterm Birth, Drissa Toure

Theses & Dissertations

Preterm birth is a complex multifactorial process. Despite the well-known role of the placenta in supporting the fetal development and maternal-fetal tolerance, the placental epigenetic modifications and preterm birth (PTB) remains poorly understood and under investigated. Various maternal and environment factors can influence epigenetic programming during fetal development to affect the functioning and structures of organs, including the placenta, which can lead to adverse pregnancy outcomes, including PTB. The understanding of the placental epigenetic alterations and maternal determinants associated with PTB are apparently indispensable for the development of actual diagnosis and methods of prevention and treatment of premature labor. The …
