Factors That Influence The Prevalence Of Food Allergy In Children Born In Industrialized Countries Vs. Developing Countries: A Literature Review & Feasibility Study, Dimitri Miguel Lacson Torres

Nursing | Senior Theses

Background

Food allergy (FA) is known to be more prevalent in industrialized countries compared to developing countries. FA is a chronic disease that can cause a range of symptoms from regional urticaria to lethal anaphylaxis. FA affects 10% of the general population and is more common in children, affecting 8% of children versus 3% of adults (Seth, D. et al., 2020). It is unclear why food allergy is more common in industrialized countries versus developing countries. Research Question What are the influential factors that affect the increasing incidence of food allergy in toddlers born in industrialized countries versus those that …


Genetic Risk Scores For Hypertension And Chronic Kidney Disease In African Americans., Aastha Kakar Dec 2023

Genetic Risk Scores For Hypertension And Chronic Kidney Disease In African Americans., Aastha Kakar

Electronic Theses and Dissertations

Hypertension (HT) and chronic kidney diseases (CKD) are complex conditions, disproportionally prevalent among African Americans (AA) and are influenced by multiple genetic as well as environmental factors. Genetic risk scores (GRS) enable the analysis of the combined effects of multiple single nucleotide polymorphisms (SNPs). This study investigates the association of blood pressure (BP) and CKD GRS with BP, hypertension (HT) and CKD; early-onset HT and CKD; and investigates interactions of the GRSs with environmental measures in AA. We observed a significant association between the BP-GRS with HT, SBP and DBP. The odds of HT for one standard deviation (s.d.) increase …

The Genetic Associations Of Circadian Rhythm And Sleep Disorder Traits With Risk Of Monoclonal Gammopathy Of Undetermined Significance And Multiple Myeloma, Brittany Crawford Oct 2023

The Genetic Associations Of Circadian Rhythm And Sleep Disorder Traits With Risk Of Monoclonal Gammopathy Of Undetermined Significance And Multiple Myeloma, Brittany Crawford

Theses and Dissertations

Background: Circadian rhythm disruption and sleep have been widely studied for their roles in immunity and cancer development. Evidence for an association of circadian rhythm and sleep traits with multiple myeloma (MM) risk is inconclusive. No studies have investigated these traits in relation to monoclonal gammopathy of undetermined significance (MGUS). Given that MGUS precedes almost all MM cases, investigating sleep and circadian rhythm in relation to both MM and MGUS is necessary. The purpose of this dissertation was to explore the genetic influences of circadian rhythm and sleep traits on the risk of MGUS and MM. Methods: Data were leveraged …

Epidemiology Of Island And Mainland Populations: How Does Culture Influence Health Risk Factors Of Non-Communicable, Chronic, And Metabolic Diseases?, Jake Thomas D. Palisoc May 2023

Epidemiology Of Island And Mainland Populations: How Does Culture Influence Health Risk Factors Of Non-Communicable, Chronic, And Metabolic Diseases?, Jake Thomas D. Palisoc

Honors Projects

Non-communicable diseases (NCDs), including chronic and metabolic diseases, are responsible for 74% of global mortality and are strongly influenced by health risk factors. Geographical differences in NCDs have been identified in several countries but have not been completely explained through cultural factors, specifically island and mainland cultures. This study aimed to develop an epidemiological framework for determining diseases with the highest mortality for further investigation regarding different health risk factors rooted in a specific population’s cultural foundations. Preliminary findings indicated diabetes type II (D2) and CKD caused by hypertension and D2 to have the highest risk factor and mortality percentage …


Predictors Of Retention Among Individuals With Hiv Initiating Antiretroviral Therapy In Ghana, Ivy Ama Okae Jan 2023

Predictors Of Retention Among Individuals With Hiv Initiating Antiretroviral Therapy In Ghana, Ivy Ama Okae

Walden Dissertations and Doctoral Studies

Abstract Managing HIV requires lifelong therapy. Retaining clients on lifelong therapeutic antiretroviral therapy (ART) ensures the suppression of viral replication and better health outcomes. The time of the start of ART management is also a factor in determining better health outcomes for persons living with HIV. This study examined the association between initiation criteria (treat all, Option B+, and CDC T-cell count < 500) and retention on ART at 12 months for 17,974 randomly selected clients in the Ghana Health Service's HIV patient electronic database. Analyses controlled for age, gender, educational status, alcohol use, treatment/adherence monitoring, and tuberculosis disease treatment. Bronfenbrenner's ecological systems theory guided the interpretation of the findings. Results shows that retention was positively associated with all treatment initiation criteria. Clients initiated with CD4 count ≤ 500 criteria seemed to be retained at 12 months on ART at a higher rate than initiation criteria based on Option B+ and treat all. The study results may contribute to positive social change by supporting CD4 testing for clients before initiation of ART to improve retention and ensure the availability and use of adherence counseling, no tuberculosis disease and its prevention, and low use of alcohol among people living with HIV. The results of this study may also provide opportunities for public health policy intervention efforts requiring a personalized, group-based approach to service delivery at the intrapersonal level, interconnected with interpersonal, meso, and meta factors at the community level.


Charting And Navigating The "Scylla And Charybdis" Conundrum Of Our Ageing Hearts - Heart Failure & Atrial Fibrillation, Simon Stewart Jan 2023

Charting And Navigating The "Scylla And Charybdis" Conundrum Of Our Ageing Hearts - Heart Failure & Atrial Fibrillation, Simon Stewart

Theses

Residing on opposite sides of the Strait of Messina between Sicily and Calabria, Scylla and Charybdis were mythical sea monsters (one a fearsome creature, the other a deadly whirlpool) described by Homer. For anyone seeking to navigate that narrow and treacherous passage, avoid one of these lethal threats and you would be devoured by the other. For many populations around the world, the conundrum of successfully preventing and/or treating heart failure (HF) to increase longevity, only to increase the probability that it will increase the number of people living with and dying from atrial fibrillation (AF), represents a conundrum of …


Pancreatic Cancer: Quantitative Study Investigating The Regional Risk Factors In North Carolina, Holly Marie Myers Jan 2023

Pancreatic Cancer: Quantitative Study Investigating The Regional Risk Factors In North Carolina, Holly Marie Myers

Walden Dissertations and Doctoral Studies

Pancreatic cancer is the fourth-leading cause of cancer-related deaths in the United States, killing more than 90% of individuals diagnosed within 5 years. Due to the lack of signs and symptoms, 82% of all pancreatic cancer cases are diagnosed in terminal stages. As such, the most powerful method to reducing the morbidity and mortality of pancreatic cancer is to further investigate the risk factors. According to the theoretical framework of the ecosocial theory, long-term exposure to exposures to unfavorable socioecological and environmental factors serve as a “web of causation” for adverse health outcomes. Using data from the North Carolina Department …

The Application Of Time Series Analysis To Injury Epidemiology Data, Eric Wayne Lundstrom Jan 2023

The Application Of Time Series Analysis To Injury Epidemiology Data, Eric Wayne Lundstrom

Graduate Theses, Dissertations, and Problem Reports

Introduction: Injury fatality rates in the United States (US) decreased throughout the majority of the 20th century, mostly due to declining rates of occupational and motor vehicle injuries. However, near the beginning of the 21st century, fatal injury rates in the US began to increase. This is principally due to the nation’s opioid epidemic, which has been characterized by different epidemic “waves”, each driven by overdoses associated with specific substances. Given the temporally dynamic nature of US injury trends, this study aimed to explore the application of time series analysis to injury data in the US. First, rates of non-fatal …

Modeling The Heterogeneous Temporal Dynamics Of Epidemics On Networks, Andrea Joan Allen Jan 2022

Modeling The Heterogeneous Temporal Dynamics Of Epidemics On Networks, Andrea Joan Allen

Graduate College Dissertations and Theses

Mathematical models of infectious disease are important tools for understanding large-scale patterns of how a disease spreads through a population. Predictions of trends from disease models help guide public health prevention and mitigation measures. Most simple disease models assume that the population is randomly mixed, but real-world populations exhibit heterogeneous patterns in the way people interact. These differences in population structure can be represented by networks. Networks can then be incorporated into disease models by using various interdisciplinary concepts and tools. Yet even network disease models often overlook that populations change over time. In this thesis, two models of infectious …

This study investigated whether sexual women with a history of sexual violence (SV), likelihood to get screened for cervical cancer would be impacted given the fear of suffering from secondary trauma during conventional screening procedures. Methods: Knowledge of cervical screening …


Relationship Between Early Years’ Activities Of Daily Living And Alzheimer’S Disease Onset, Linyi Fan Jan 2022

Relationship Between Early Years’ Activities Of Daily Living And Alzheimer’S Disease Onset, Linyi Fan

Walden Dissertations and Doctoral Studies

A few promising studies have indicated that activities of daily life (ADL) may be a useful way of predicting Alzheimer’s Disease (AD). However, the existing cross-sectional studies fail to show how ADLs in early years predict AD, and how social factors influence health either in addition to or in interaction with individual risk factors. Using a social epidemiology framework, this study examined the relationship between early years’ ADL and the development of AD in later years. This quantitative study included 4,526 participants derived from the Health and Retirement Study (HRS) dataset. The dependent variable was whether the participant has been …

An Epidemiologic Study Of Vaccination Exemptions And Pertussis Risk, Corinne B. Tandy Dec 2021

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 …
