Measuring The Effect Of A Poverty Simulation On Cultivating Empathy In Healthcare Professions Students, H. Alex Hoyen

Master of Science in Population Health Capstone Presentations

Introduction: Poverty is generally defined on a fiscal metric despite the fact that it disrupts every facet of a patient’s life. The United Nations (UN) recently published its campaign focused on Ending Poverty. In this publication, the UN describes poverty as “entailing more than the lack of income and productive resources to ensure sustainable livelihoods.” The manifestations include hunger, safe housing, transportation, education, and social discrimination. To fully appreciate the effects of conditions such as poverty requires a deeper understanding of the complex social environment that impoverished individuals are forced to navigate. Poverty simulations are one practice to provide a …

A Dynamic Risk Model For Multitype Recurrent Events, Alokananda Ghosh, Wenyaw Chan, Naji Younes, Barry R Davis

Faculty, Staff and Student Publications

Recurrent events can occur more than once in the same individual; such events may be of different types, known as multitype recurrent events. They are very common in longitudinal studies. Often there is a terminating event, after which no further events can occur. The risk of any event, including terminating events such as death or cure, is typically affected by prior events. We propose a flexible joint multitype recurrent-events model that explicitly provides estimates of the change in risk for each event due to subject characteristics, including number and type of prior events and the absolute risk for every event …

Beyond The Bmi: Expanding Quantitative Methods To Study Health For All Bodies, Kieran Chase, Daniel Oron

OHSU-PSU School of Public Health Annual Conference

The public health field is beginning to reckon with its role in perpetuating and reinforcing systemic anti-fatness. Emerging evidence for the devastating health impacts of stigma call into question decades of research and policy that labels the size of people’s bodies as diseased. However, even as we acknowledge the harmful effects of stigma, the field is materially and institutionally invested in a health paradigm that centers weight loss and size-related proxies for health, such as the BMI. Public health scholars interested in questions related to nutrition, chronic disease, and exercise must begin to expand their research focus to imagine non-stigmatizing …

Serotonin And Migraine, Sophia A. Kogan

OHSU-PSU School of Public Health Annual Conference

Migraine, experienced by more than 1 billion people, is the second leading cause of disability worldwide. It is a physiologically complex disorder with nervous, vascular, and inflammatory components, and is associated with genetic factors and environmental influences. Migraine triggers are poorly understood, and sufferers have little control in preventing migraines from occurring. The aim of this review is to bridge the physiological migraine processes with lifestyle behaviors that can be modified by individuals, focusing on serotonin.

Migraines can be initiated when an external event triggers the release of vasodilators such as calcitonin gene-related peptide (CGRP), leading to cranial vasodilation, headache, …

Faculty, Staff and Student Publications

Associations between human genetic variation and clinical phenotypes have become a foundation of biomedical research. Most repositories of these data seek to be disease-agnostic and therefore lack disease-focused views. The Type 2 Diabetes Knowledge Portal (T2DKP) is a public resource of genetic datasets and genomic annotations dedicated to type 2 diabetes (T2D) and related traits. Here, we seek to make the T2DKP more accessible to prospective users and more useful to existing users. First, we evaluate the T2DKP's comprehensiveness by comparing its datasets with those of other repositories. Second, we describe how researchers unfamiliar with human genetic data can begin …

The Dietary Approaches to Stop Hypertension (DASH) diet is recommended for cardiovascular disease prevention. We aimed to identify protein biomarkers of the DASH diet using data from 2 randomized feeding studies and validate them in an observational study, the ARIC (Atherosclerosis Risk in Communities) study.

Methods and Results

Large‐scale proteomic profiling was conducted in serum specimens (SomaLogic) collected at the end of 8‐week and 4‐week DASH diet interventions in multicenter, randomized controlled feeding studies of the DASH trial (N=215) and the DASH‐Sodium trial (N=396), respectively. Multivariable linear regression models were used to compare the relative abundance of 7241 proteins …

Pattern Dynamics And Stochasticity Of The Brain Rhythms, Clarissa Hoffman, Jingheng Cheng, Daoyun Ji, Yuri Dabaghian

Faculty, Staff and Students Publications

Our current understanding of brain rhythms is based on quantifying their instantaneous or time-averaged characteristics. What remains unexplored is the actual structure of the waves—their shapes and patterns over finite timescales. Here, we study brain wave patterning in different physiological contexts using two independent approaches: The first is based on quantifying stochasticity relative to the underlying mean behavior, and the second assesses “orderliness” of the waves’ features. The corresponding measures capture the waves’ characteristics and abnormal behaviors, such as atypical periodicity or excessive clustering, and demonstrate coupling between the patterns’ dynamics and the animal’s location, speed, and acceleration. Specifically, we …

Parental Perceptions Of The Hpv Vaccine For Prevention Of Anogenital And Oropharyngeal Cancers, Beth I. Schwartz, Merissa Maccani, Shalini Bansal, Meghan Gannon

Department of Obstetrics and Gynecology Faculty Papers

Background and Objectives

Human papillomavirus (HPV) is implicated in the development of both anogenital and oropharyngeal cancers. Although HPV vaccination prevents the majority of anogenital and head and neck cancers (HNC), vaccination rates remain low, especially among males. Known barriers to vaccination are knowledge gaps and vaccine acceptability. The objective of this study is to explore parental knowledge, perceptions, and decision-making processes about HPV and HPV vaccination for both anogenital and HNC.

Methods

This qualitative study recruited parents of children and adolescents aged 8–18 to participate in semi-structured telephone interviews. Data were analyzed using thematic analyses, informed by an inductive …

Is Adiposity Related To Repeat Measures Of Blood Leukocyte Dna Methylation Across Childhood And Adolescence?, Luke Montrose

Public and Population Health Faculty Publications and Presentations

Epigenetic modifications such as DNA methylation may influence gene expression and phenotypes, including obesity in childhood. The directionality of this relationship is nevertheless unclear, and some evidence suggests that adiposity modifies the epigenome, rather than the other way around. In this pilot study, we utilize data from the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) study to examine whether measures of adiposity in childhood and early adolescence are associated with repeated measures of blood leukocyte DNA methylation at LINE-1 repetitive elements and two genes implicated in growth and adiposity: H19 and HSD11B2. Longitudinal epigenetic data were generated …

Discrepancies In The Estimation Of Vaping Rates Among College Students, Cameron J. Klug

Honors Thesis

The use of nicotine inhalation products among college students is an imminent public health issue, with young-adult populations being particularly likely to take up nicotine use during their college years (American College Health Association, 2021). Even with elevated levels of nicotine vapor product use in college populations, existing surveys may still underestimate the prevalence of nicotine use among this population. This study aimed to address this issue by conducting a survey of college students at the University of South Dakota, using a peer-to-peer approach to reduce social desirability bias. The study’s survey directly stated it was being issued and analyzed …

Oral Health In Relation To The Covid-19 Pandemic, Anika L. Gram

Honors Thesis

Oral health has seen significant changes through the Covid-19 pandemic. Many people experienced the lifestyle alteration of wearing a mask for a major portion of their day-to-day life, and some went to the dentist significantly less than they did pre-pandemic. The literature review explores dental practices during the Covid-19 pandemic. It also examines mask-wearing behaviors both before and during the pandemic and the research that has been conducted previously regarding the potential effects of mask-wearing. Despite the decrease in use of masks post-pandemic, many healthcare professionals continue to wear masks daily. Additionally, in the event of future disease outbreak, it …

The Economic, Mental Health, And Social Stressors During The Covid-19 Pandemic Among Native Americans In South Dakota, Savannah E. Lukkes

Honors Thesis

American Indian/Alaska Native (AI/AN) communities test positive for COVID-19 and experience higher mortality than other racial and ethnic groups. These high rates of vulnerability could be connected to the systemic inequalities that have been experienced for centuries. This study aimed to compare socioeconomic stressors, concerns, and mental health experiences during the early COVID-19 pandemic between AI/AN and non-AIAN populations in South Dakota. The study sample (n=1,586) was grouped by AI/AN and non-AI/AN status based on self-identification of being AI/AN alone or in combination with another race/ethnicity. Participant responses to socioeconomic stressors and concerns (e.g., top concerns, level of concern, self-isolation, …

Migrants Sans Papiers: The Impact Of Cantonal Program And Policy Discrepancies On Undocumented Migrant Healthcare Utilization In Switzerland, Denise Peng

Independent Study Project (ISP) Collection

While Switzerland houses what is generally considered one of the best healthcare systems globally, regional policy discrepancies leave undocumented migrants (UDM) in precarious conditions that threaten the nation’s claim to universal health coverage. Critical analyses of existing UDM-catering structures in different cantons, the Swiss Confederation member states, reveal that local discrepancies in healthcare utilization are functional gradients of cantonal support and public endorsement. Relationships with these authorities are instrumental in steering health outcomes not only with program funding and outreach but also management of studies to better understand UDM health determinants and inform future preventative measures.

Undergraduate Major And Covid-19 Vaccination Rates Among University Of South Carolina Students, Rebecca Stoltz

Senior Theses

The COVID-19 pandemic brought new vaccines to the forefront of public attention, and with it came a wide array of different opinions. The University of South Carolina did not require students to receive a COVID vaccine, so the decision was left entirely to the individual. Many of my peers have shown support or voiced opposition to the vaccine, and I noticed that those who opposed tended to fall within certain major categories. This study seeks to determine whether a correlation exists between undergraduate major groups and vaccination status, and to gather student attitudes and concerns surrounding vaccines. Among 172 survey …

Faculty, Staff and Student Publications

OBJECTIVE: Although advanced stage epithelial ovarian cancer is widely considered life-threatening, 17% of women with advanced disease will survive long-term. Little is known about the health-related quality of life (QOL) of long-term ovarian cancer survivors, or how fear of recurrence might affect QOL.

METHODS: 58 long-term survivors with advanced disease participated in the study. Participants completed standardized questionnaires to capture cancer history, QOL, and fear of recurrent disease (FOR). Statistical analyses included multivariable linear models.

RESULTS: Participants averaged 52.8 years at diagnosis and had survived >8 years (mean:13.5); 64% had recurrent disease. Mean FACT-G, FACT-O, and FACT-O-TOI (TOI) scores were …

Prevalence Of Sars-Cov-2 Antibodies In Liberty University Student Population, Emily Bonus

Senior Honors Theses

In 2020, the virus SARS-CoV-2 gained attention as it spread around the world. Its antibodies are poorly understood, and little research focuses on those with few COVID-19 complications yet large numbers of close contacts: university students. This longitudinal study recorded SARS-CoV-2 antibody presence in 107 undergraduate Liberty University students twice during early 2021. After extensive data cleaning and the application of various statistical tests and ANOVAs, the data seems to show that in the case of COVID-19 infections, SARS-CoV-2 IgM antibodies are immediately produced, and then IgG antibodies follow later. However, the COVID-19 vaccine causes the production of both IgM …

OBJECTIVES: African Americans suffer disproportionately from cancer compared to their White counterparts. Racism may be an important determinant, but the literature on its association with cancer screening is limited. We examine associations between racism and cancer screening among a sample of African Americans.

DESIGN: Guided by the Public Health Critical Race Praxis and the Behavioral Model of Health Services Use, we conducted a multilevel, cross-sectional study using cancer risk assessment data collected from 405 callers to the 2-1-1 Texas helpline. We merged these data with contextual data from the U.S. Census Bureau. We assessed perceived racial discrimination using the Experiences …

Menstrual Justice In Theoretical Context, Vivian E. Hamilton

Faculty Publications

This Essay reviews and places into theoretical contexts Bridget Crawford and Emily Waldman’s invaluable book Menstruation Matters. Although the authors themselves do not explicitly label the theoretical approach that undergirds their work, much of Menstruation Matters: Challenging the Law’s Silence on Periods falls within the liberal feminist legal tradition typical of post-civil rights second-wave feminism. Their work also embodies aspects of critical feminist approaches to law. Crawford & Waldman expose the discriminatory effects of facially neutral laws, the limits of formal equality, and the pitfalls of essentializing or making universal claims about categories of individuals—including women and menstruators. In …

Oral Health Considerations For Aging Patients Living With Hiv/Aids, Madeleine Daily Dds, Susan Liu Dds, Yuna Park Dds, Mph, Ms, Emily Byington Msw, Ivette Estrada Ma, Mphil, Sunil Wadhwa Dds, Carol Kunzel Phd

The New York State Dental Journal

People living with HIV/AIDS (PLWH) have an increased life expectancy due to advances in antiretroviral therapy. In 1996, the life expectancy for a 20-year old living with HIV was 39-years old; today, it is >70-years old. As life expectancy increases, PLWH are burdened with age-associated comorbidities. This paper reviews the interaction between aging and HIV and how it affects social, physical, and oral health issues. The shift in demographics presents new challenges for clinicians in how to identify, address, and manage these complex manifestations. This review summarizes how to approach HIV-related changes when providing care as a dental clinician.

Examining Associations Between Social Needs And Mental Health Among Youth And Young Adults With Diabetes, Andrea Danielle Brown

Theses and Dissertations

Household food insecurity (HFI) disproportionally affects people with diabetes living in the United States and is more likely to occur in households with children and in minority race/ethnicity households. Food insecure people with youth-onset diabetes likely have increased risk for poor mental health due to dealing with stress and cost related to diabetes management, especially if facing additional health-related social needs that intersect with HFI. If left untreated, poor mental health among youth and young adults (YYA) with diabetes can lead to diabetes-related complications, increased health care costs, and mortality. Yet few studies have examined associations between HFI and mental …

Ultra-Processed Food Consumption And Risk Of Liver Cancer, Longgang Zhao

Theses and Dissertations

Background: Studies have shown positive associations between ultra-processed food (UPF) intake and obesity and type 2 diabetes, two risk factors for liver cancer. However, the relationship between UPF intake and liver cancer has scarcely been studied. We aimed to evaluate the association between UPF intake and the risk of liver cancer in three prospective cohorts and further explore the role of genetic predisposition to fatty liver diseases and biomarkers of liver health on modifying the association.

Methods: We used data from the Nurses’ Health Study (1986-2012), the Health Professionals Follow-up Study (1986-2012), and UK Biobank (2006-2020). Diet was assessed with …

Multilevel Description Of Spotted Fever Group Rickettsia Among Humans, Animals, And The Environment In Miraflores, Colombia, And South Carolina, Usa, Lidia Gual Gonzalez

Theses and Dissertations

Tick-borne diseases are emerging worldwide due to environmental shifts caused by land fragmentation and climate change. Among the most important ones spotted fever group rickettsioses (SFGRs) are of particular interest due to their wide species variety and high pathogenicity. Given the global spotted fever group rickettsia (SFGR) distribution, evaluation and comparison of different populations is critical to better understand these pathogens' epidemiology and unravel the risk factors affecting disease occurrence. Consequently, this dissertation investigates SFGR highlighting the One Health framework, assessing animals, humans, and the environment. The first part includes an evaluation at the household level using human and canine …

Wernicke's Encephalopathy: Mapping The Risk Factors Throughout The State Of South Carolina, Shannon M. Rychener

Senior Theses

Wernicke’s Encephalopathy is a consistently underrecognized neurodegenerative brain disorder resulting from prolonged thiamine deficiency. Clinical presentation of the disease results from brain lesions attributable to thiamine deficiency. Because these lesions occur in various locations in the cerebral cortex, symptoms can vary significantly. Varied presentation of symptoms, in addition to the lack of a widely accepted biomarker for the disorder cause challenges to clinicians when identifying and diagnosing the disorder. Due to these challenges, healthcare providers must heavily rely on patient history and risk factor prevalence when multiple symptoms of the disorder are present. By mapping the prevalence of the four …
