Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh
Undergraduate Research Posters
Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Detailing The Genetic And Environmental Influences Shared Between Conventional And Electronic Cigarette Use Across Measures Of Initiation And Past 12-Month Use, James Clifford
Theses and Dissertations
Introduction. Tobacco use is a public health crisis with nearly 500,000 Americans suffering premature mortality attributable to tobacco use in 2014. New development efforts have created new nicotine delivery systems whose health consequences are not yet fully understood such as electronic cigarettes (ECIG). It is possible there are shared genetic and environmental factors that influence an individual’s liability to initiate cigarette (CIG) or ECIG use, as both systems are designed to deliver nicotine.
Methods. Four study designs were used to resolve the genetic and environmental influences that underlie CIG and ECIG initiation. A twin study, scoping review, genome-wide association study …

Exploring Predictors In The Receipt Of Patient/Family-Centered Care, Arami Anwell
Theses and Dissertations
Study 1
OBJECTIVES: The research aim of this study was to identify predictors associated with the receipt of PFCC among U.S. children/families
METHODS: Caregivers of 38,803 non-institutionalized children, aged 0 to 17 years, were surveyed by the National Survey of Children’s Health (NSCH) 2018–20019. Patient/family-centered care (PFCC) was measured using five components of health care delivery that were answered on a 4-point Likert scale. Logistic regression models were analyzed for the overall receipt of PFCC and each component of PFCC, with survey weighting added to adjust for complex sampling design.
RESULTS: Many predictors were associated with the receipt of PFCC. …
A Mixed Methods Approach To Examine Racial Disparities In Adherence To Surveillance Mammography Among Breast Cancer Survivors, Megan C. Edmonds
A Mixed Methods Approach To Examine Racial Disparities In Adherence To Surveillance Mammography Among Breast Cancer Survivors, Megan C. Edmonds
Theses and Dissertations
PURPOSE: Annual surveillance mammography is a critical part of routine cancer care for breast cancer (BC) survivors; reducing mortality by 39%. However, disparities exist with regard to adherence to surveillance mammograms among BC survivors; Black women are 44% less likely to adhere than their White counterparts. Despite the existence of this racial disparity for over a decade, little is known about factors that explain reasons for Black BC survivors’ non-adherence. This is because most studies have not evaluated the role of healthcare delivery or psychosocial factors. Guided by the Behavioral Model for Vulnerable Populations, the purpose of this mixed methods …

The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan
The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan
Theses and Dissertations
Background: Postpartum depression (PPD) is a phenomenon that affects nearly 10-15% of pregnancies in the US. It is characterized by depressed mood or anhedonia and lasting for more than 2 weeks. PPD changes how moms interact with family members and child-rearing behavior. Depression is a phenomenon that is also known to affect the psychopathology of children. However, the specifics of how postpartum depression impacts children remains controversial. Many studies do not control for major depressive disorder which makes it difficult to disentangle the impact depression has within the first year of life. Furthermore, other PPD risk factors may be confounding …

Estimating Causal Effects In The Presence Of Spatial Interference, Keith W. Zirkle
Estimating Causal Effects In The Presence Of Spatial Interference, Keith W. Zirkle
Theses and Dissertations
Environmental epidemiologists are increasingly interested in establishing causality between exposures and health outcomes. A popular model for causal inference is the Rubin Causal Model (RCM), which typically seeks to estimate the average difference in study units' potential outcomes. If the exposure Z is binary, then we may express this as E[Y(Z=1)-Y(Z=0)]. An important assumption under RCM is no interference; that is, the potential outcomes of one unit are not affected by the exposure status of other units. The no interference assumption is violated if we expect spillover or diffusion of exposure effects based on units' proximity to other units and …

Economic Burden Of Renal Cell Carcinoma (Rcc) And Treatment Patterns, Overall Survival And Healthcare Costs Among Older Metastatic Rcc Patients, Hrishikesh P. Kale
Economic Burden Of Renal Cell Carcinoma (Rcc) And Treatment Patterns, Overall Survival And Healthcare Costs Among Older Metastatic Rcc Patients, Hrishikesh P. Kale
Theses and Dissertations
Background
Renal cell carcinoma (RCC) is the most common type of kidney cancer. Patients diagnosed with metastatic RCC (mRCC) have shorter overall survival compared to those diagnosed at earlier stages. Several targeted therapies, which cost from $7,000 - $16,000 per month have been approved since 2005 to treat mRCC. In addition, there is a growing interest in the use of cytoreductive nephrectomy (CN) with targeted therapies among mRCC patients. However, little is known regarding the economic burden of RCC and role of CN and prescribing patterns of targeted therapies among older mRCC patients.
Objectives
1) To assess the economic burden …
The Impact Of Mother–Father Relationship, Social Support And Neighborhood Context On Preterm Birth, Timothy O. Ihongbe
The Impact Of Mother–Father Relationship, Social Support And Neighborhood Context On Preterm Birth, Timothy O. Ihongbe
Theses and Dissertations
Background: Preterm birth is a major public health concern in the US. Previous studies have suggested that quality of the mother-father relationship, social support, and neighborhood violence may be associated with preterm birth; however, findings are equivocal.
Objectives: The main objectives of this dissertation were: 1) to determine the modifying effect of perceived residential environment on the association between quality of mother–father relationship and preterm birth in a sample of African-American women, 2) to examine whether the receipt of social support modifies the association between neighborhood violence exposure and preterm birth in a nationally representative sample of US women, and …

The Role Of Social Networks In Breastfeeding Duration, Jordyn T. Wallenborn
The Role Of Social Networks In Breastfeeding Duration, Jordyn T. Wallenborn
Theses and Dissertations
Background: The United States has one of the lowest rates of breastfeeding in the world. Studies hypothesize that inadequate social support from healthcare providers, family members, and employers may have contributed to the low breastfeeding rate. This study aims to: 1) examine the importance of each individual (father, maternal grandmother, paternal grandmother, obstetrician, and pediatrician) within the social support network on breastfeeding initiation and duration, 2) determine the relationship between type of prenatal care provider and time to breastfeeding cessation, and 3) examine the role of breastfeeding intention and confidence as mediators in the association between workplace support and breastfeeding …
Drinking Motives Underlying Internalizing And Externalizing Pathways To Alcohol Misuse In College Students, Jeanne Savage
Drinking Motives Underlying Internalizing And Externalizing Pathways To Alcohol Misuse In College Students, Jeanne Savage
Theses and Dissertations
Alcohol misuse, including heavy episodic use and negative consequences, is a major public health concern and a particular problem among college students. The etiology of alcohol misuse is not well resolved, with multiple and often contradictory factors implicated in its development. Genetic factors influence alcohol misuse but few specific genes have been identified. A potential reason for these challenges is that alcohol misuse is phenotypically and genetically heterogeneous; that is, there are multiple causal pathways underlying its development. Previous typologies have suggested that distinct internalizing and externalizing pathways are involved, with corresponding differences in profiles of personality, temperament, and comorbid …
Health Aid In Africa: Placement, Service Utilization, And Benefit, Carrie Dolan
Health Aid In Africa: Placement, Service Utilization, And Benefit, Carrie Dolan
Theses and Dissertations
While the health sector has attracted significant foreign aid, evidence on the effectiveness of this support is mixed. This dissertation examines the allocation of health aid within the context of placement, service utilization, and benefit. The first paper examined the sub-national allocation of Chinese development aid projects across Africa. I determined how political preferencing of Chinese aid specifically, allocating aid to the birth region of the current political leader differs across sectors such as health, education, and transportation. I find some evidence that aid, more broadly defined, is subject to political preferencing in recipient countries, which could potentially limit its …
