The Effect Of Agricultural Exposures And Genetics On Respiratory Phenotypes, Lisa W. Boyd

Theses & Dissertations

Agricultural workers are at risk for respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and chronic bronchitis, due to exposures and inflammatory agents found in their work environment. While previous studies have been conducted to examine agricultural effects of chronic respiratory diseases more closely, there are still several significant gaps in the existing literature.

This dissertation explores the relationship between agricultural exposures and respiratory diseases. Utilizing two populations, the Keokuk Country Rural Health Study and the AgLung Study, this research: 1) used principal factor analysis (PFA) to distill exposure data into essential variables characterizing long-term agricultural exposures in order …

Surveillance Of Non-Fatal Agricultural Injuries Among Farm Operators In The Central States Region Of The United States, Ketki Patel

Theses & Dissertations

Agriculture is a major industry in the U.S. with high rates of fatal and non-fatal occupational injuries. The dynamic nature of the U.S. agriculture industry, regional variations in farming practices, and the diverse workforce make surveillance of injuries challenging. A recent National Academies (U.S.) evaluation reported that data for non-fatal agricultural injury are scarce, and mainly available through national surveys. Limited data are available for employees in the agriculture sector, especially farm owners and operators. The objectives of this study were to- 1) review and evaluate existing survey-based systems for surveillance of non-fatal agricultural injuries on U.S. farms, and 2) …

Psychological Aspects Of Head And Neck Cancer, Katherine Rieke

Theses & Dissertations

Patients with head and neck cancer may be at increased risk for depression diagnosis when compared to other cancer sites, both before and after their cancer diagnosis. Behavioral risk factors for head and neck cancers, including tobacco and alcohol use, may be indicative of depression before cancer diagnosis. Further, head and neck cancers and their treatments can cause serious morbidity among patients, including physical disfigurement and loss of function. Additionally, these cancers are often accompanied by social stigma, personal shame, and guilt. While there is a significant body of research examining depression in this cancer population, there are still several …

Human Papillomavirus And Its Impact On Vulnerable Populations, Harpriya Kaur

Theses & Dissertations

Human papillomavirus (HPV) is the most common sexually transmitted infection. The infection is higher in certain racial/ethnic groups and those who are immunocompromised including pregnant women. Because immune system is suppressed during pregnancy, women are at higher risk of various types of infection including HPV, a known risk factor for pregnancy complications. However, its role in adverse pregnancy outcomes is unclear. Another high risk population is Northern Plain American Indian. In the Northern Plains region, American Indian women have significantly higher rate of HPV infection than white counterparts and are infected with different types of HPVs than the general population. …

Global Trends In Cancer Burden Based On Geographic Location, Socio-Economic Status And Demographic Shift, Sanjib Chowdhury

Theses & Dissertations

The global burden of cancer is rising at an alarming rate. It remains as one of the top causes of morbidity and mortality worldwide. It is predicted that within 2020, there will be 15 million new cases of cancer in the world, with cancer-related deaths increasing to 12 million. According to the World Health Organization (WHO), the global cancer burden is expected to surge 57% worldwide in the next 20 years. A significant rise in cancer burden will occur in the low-income and middle-income (developing) countries not only due to demographic shifts, but also by the transition of risk factors …
