The Association Between Child Abuse And Attempted Suicide In Hong Kong, Hing Sang Wilfred Wong

Walden Dissertations and Doctoral Studies

Children are the cornerstone of the community as well as the future of society. Child abuse and suicide among the young population is a serious and prevalent problem. Through a number of survey studies undertaken in other countries including Canada, United States, and Australia, researchers demonstrated that child abuse was related to suicidal behavior. However, this association had not been examined in Hong Kong. However, the number of hospital admissions for child abuse in Hong Kong had increased from 15.6 to 61.9 per 100,000 between 1995 and 2015 and 3.7% of child abuse cases had previously recorded suicide attempts. This …

Type 2 Diabetes Mellitus And Colorectal Cancer Risk And Survival In Oman, Rose Ngozi Mafiana

Walden Dissertations and Doctoral Studies

Type 2 diabetes mellitus (T2DM) and colorectal cancer (CRC) are 2 chronic diseases with common risk factors related to physical inactivity, obesity, and diet. Literature on T2DM as a risk factor for CRC development and survival in Oman is scarce. Using de-identified archival data provided by Sultan Qaboos University Hospital (SQUH) Oman, a retrospective, case-control, and time-to-event study designs were used to compare odds of developing CRC, and survival rates among adults with and without T2DM. The ecosocial theory provided the theoretical base for this research. Logistic regression was used to examine the odds of developing CRC among 114 cases …

Specimens were cultured and molecular typing was performed. In total, 340 samples were tested, of which 70 (20.6%) were GDH positive, with toxin detected in 19 (5.6%). Toxigenic C. difficile was isolated from 37 specimens (10.9%), while a further 36 (10.6%) nontoxigenic isolates were identified. The most …

Socially Assigned Race, Reactions To Perceived Racial Discrimination And Type Ii Diabetes Mellitus, Jourdyn A. Lawrence

Theses and Dissertations

Background: Numerous studies have utilized race to document health inequities. As race is considered a social classification of persons based upon physical traits, studies have begun to consider socially assigned race defined as the race/ethnicity perceived by others. Socially assigned race may serve as the basis for differential or unfair treatment of persons ascribed to historically oppressed groups. Socially assigned race may also provide additional insight into racial health disparities, particularly among Latino populations who are commonly defined by their ethnicity. This study assesses the relationship between self-identified and socially assigned race/ethnicity and tests the moderating effects of emotional and …

Association Between Diabetes And Cancer In Indian And Us Populations Using Longitudinal Study Design, Shraddha S. Vyas

Theses and Dissertations

Background: There is growing evidence of association between diabetes and cancer. No studies have been conducted in India evaluating this association. With the current epidemiologic, nutritional and economic transition in India, it becomes extremely important to examine this association in an Indian population. Additionally, difference in association exists based on different cancer subtypes. Research has shown that diabetes is associated with an increased risk of colorectal cancer. However most of these studies suggest detection bias to be one of the probable reasons for this association. Additionally, the common risk factors shared by both these conditions are considered to one of …

Effects Of A Mindfulness Based Intervention On Diurnal Cortisol In Cancer Survivors, Susannah Small

Theses and Dissertations

Background. There are approximately 15.5 million individuals alive today in the U.S. with a personal history of cancer. For this large and growing population, ill effects associated with cancer diagnosis and treatment include both physical and psychosocial symptoms adversely affecting quality of life. One low-risk alternative to conventional pharmaceutical use in treating these symptoms is mindfulness practice. Research on self-reported measures provides strong evidence that this type of intervention improves quality of life for cancer survivors, but evidence of impact on objective measures is limited. Cortisol, the body’s primary stress hormone, is one relatively easy to measure indicator that …

Assessing The Relationship Between Periodontal Disease And Subsequent Inflammatory Responses And Headache Disorders, Bryn E. Davis

Theses and Dissertations

Headaches are the sixth leading cause of disability worldwide, and the third leading cause of disability amongst those aged 50 and older. Several headache disorders, including migraines, have been associated with nitric oxide production. It is widely accepted that the pain associated with headache disorders is due to the ability of nitric oxide to function as a vasodilator. While nitric oxide is a known vasodilator and has been linked to headache disorder, it is also produced in response to bacterial infections. Periodontal disease is the result of long term bacterial infections occurring in the gum line and nitric oxide is …

A Possible Mechanism For Leptin’S Role In Lung Function Independent Of Body Mass Index: Investigating Leptin’S Genotype, Dna, Methylation, And Serum Protein Levels, Mitra Yousefi

Theses and Dissertations

Background: Leptin, initially believed to simply be a satiety hormone responsible for obesity, is now recognized as a pleiotropic cytokine that is involved in many biological processes; including the body’s host inflammatory response. Clinically, leptin may affect lung function although research in this area is limited. It is also known that the leptin receptor is necessary for the activation of the leptin protein, making it an important protein to consider. Furthermore, single nucleotide polymorphisms (SNPs) and DNA methylations of the leptin and leptin receptor genes (LEP and LEPR respectively) may provide important insight on the relationship that leptin has …

Analysis Of Food Exposures In Foodborne Disease Outbreaks, Alecia T. Alianell

Theses and Dissertations

Foodborne illness remains a serious public health problem in the United States in general as well as South Carolina in particular. Obtaining good food ingestion histories as well as possible risky environmental exposures is one of the earliest, most important tasks to complete in any foodborne outbreak investigations. Because time is of the essence in investigations, we have evaluated a rarely used biostatistical method, Random Forests, to data obtained from DHEC. Random Forests has the potential to facilitate more rapid identification of foods or environmental exposures that may be associated with outbreaks. We also examined previous cases of salmonellosis using …

BACKGROUND: Despite the World Health Organization (WHO) regularly updating guidelines to recommend earlier initiation of antiretroviral therapy (ART) in children, timely enrollment into care and initiation of ART in sub-Saharan Africa in children lags behind that of adults. The impact of implementing increasingly less restrictive ART guidelines on ART initiation in Central Africa has not been described. MATERIALS AND METHODS: Data are from the Central Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) pediatric cohort of 3,426 children (0-15 years) entering HIV care at 15 sites in Burundi, DRC, and Rwanda. Measures include CD4 count, WHO clinical stage, age, and …

Early Life Factors And Health Outcomes In Children And Mothers, Olubunmi Olufunke Orekoya

Theses and Dissertations

This dissertation focused on early life exposures and their impact on children and mothers’ health. It consists of three distinct studies with an overarching goal of understanding how early life factors influence health outcomes among children and mothers. The broad aims are: 1) to examine the association between maternal gestational weight gain and offspring weight at 1 year, while assessing the mediating role of birth weight; 2) to determine the association between breastfeeding practices and development of allergic conditions (eczema/skin allergy, hay fever/respiratory allergy, and asthma); and 3) to examine the association between breastfeeding and postpartum weight retention at 12 …

The Association Between Sexual Risk Behaviors Of Latinos And Hiv Knowledge In South Carolina, Danielle Nicole Sill

Theses and Dissertations

HIV/AIDS inordinately impacts Hispanics/Latinos, which are the fastest growing minority group in the United States. 16,222 South Carolinians are infected with HIV, with 70 new cases being diagnosed each month. Few studies have been conducted to determine if HIV knowledge is associated with sexual risk behaviors in South Carolina. Bilingual/bicultural interviewers conducted a survey of Latinos living in the Pee Dee and Midlands regions of South Carolina. The survey consisted of questions regarding demographic characteristics, HIV knowledge, and sexual risk behaviors. We enrolled 203 participants in which 193 were eligible for our study (97 females and 96 males). We hypothesized …

The Impact Of Autoimmune Disease On Breast Cancer Survival, Samantha Truman

Theses and Dissertations

Background Breast cancer is the second leading cause of cancer death for women in developed countries, while autoimmune disease effects approximately 10 million people in the United States, of which approximately 80% are female. Both diseases are associated with hormonal risk factors and are related to the divergent effects of the cellular and humoral immunity that is associated with the T-helper 1 and T-helper 2 immune response. To investigate the potential implications that autoimmune disease may have on breast cancer-specific mortality, we have conducted a population-based retrospective cohort study of women who were diagnosed with breast cancer between January 1, …

Trends In Gestational Weight Gain In South Carolina, 2004 - 2015, Marilyn Elizabeth Wende

Theses and Dissertations

Objective: Excessive and inadequate gestational weight gain (GWG) are associated with a myriad of adverse pregnancy outcomes. The objective of this study was to examine secular trends in GWG in South Carolina (SC) from 2004 to 2015. We hypothesized that there was a trend of higher GWG z scores (GWGZ) over this 11-year time period after adjusting for changes in population characteristics. We also hypothesize that a trend of higher mean GWGZ at higher percentiles is more apparent for African Americans, rural women, and women who are overweight or obese before pregnancy.

Data and Methods: Data came from SC …
