The Health Care Costs Of Financial Exploitation In Maine, Kimberly I. Snow Mhsa, Yvonne Jonk Phd, Deborah Thayer Mba, Catherine Mcguire Bs, Stuart Bratesman Mpp, Charles A. Smith Phd, Erika C. Ziller Phd

Disability & Aging

This study sought to determine the Medicare and Medicaid costs experienced by dual eligible older adults in Maine for whom Maine Adult Protective Services (APS) substantiated allegations of elder financial exploitation and to compare them to those of Maine’s general older population. The analysis is an important step forward in estimating the medical costs associated with elder abuse.

Elder financial exploitation may result in significant public burden on Medicare and Medicaid, shouldered by taxpayers. Efforts to detect, investigate, prosecute, and mitigate this abuse will benefit not only the victims, but also the financial stewardship of these public programs.


The Influence Of Interpersonal Dyadic Differences On Condom Use Among Men Who Have Sex With Men, Andrew M. O'Neil May 2019

The Influence Of Interpersonal Dyadic Differences On Condom Use Among Men Who Have Sex With Men, Andrew M. O'Neil

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: Men who have sex with men (MSM) continue to be disproportionately affected by HIV/AIDS and other STIs. Condom use is one of the most effective methods of prevention, but rates of condom use have been steadily declining among MSM. Therefore, determining what factors influence condom use decision-making among MSM is important. Interpersonal factors such as physical attractiveness, race, and age have been explored in relation to condom use. However, there is a dearth of research exploring the influence of discrepancies between casual partners in these social categories and its influence on condom use directly.

Purpose: The purpose of this …


The Effects Of A Dementia Simulation Experience On Attitudes Towards People With Dementia, Micah Huckabee May 2019

The Effects Of A Dementia Simulation Experience On Attitudes Towards People With Dementia, Micah Huckabee

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: The neurodegenerative effects of dementia resulting in cognitive and behavioral impairments is plausibly one of the reasons for a societal stigma towards individuals with dementia. Societal stigmas are associated with decreased life satisfaction, depressive symptoms, and decreased psychological well-being for stigmatized individuals. In an effort to improve attitudes towards individuals with dementia, this study utilized a dementia simulation to measure attitudinal changes after a dementia simulation. Methods: There were 33 participants in this study (13 male and 20 female) between the ages of 18 and 25. Participants completed a Dementia Attitudes Scale (DAS) survey, and then they dressed in …

It's Not Easy - Impacts Of Suicide Prevention Research On Study Staff, Jason I. Chen, Ginnifer L. Mastarone, Lauren M. Denneson

Communication Faculty Publications and Presentations

Suicide prevention researchers who work with individuals at high risk of suicide or are exposed to details of suicide attempts and deaths may experience negative impacts on their own well-being. This is not unlike the experiences of mental health providers, where repeated exposure to clients' difficult experiences gas long been identified as an occupational risk (Molnar et al., 2017). however, there have been few studies evaluating how exposure to details of suicide-related behavior impacts researcher well-being. This gap in the literature is worrisome, as researcher' mental health and well-being might be negatively impacted by repeated exposure to graphic details of …

Assessing Hospitalizations Due To Assaults At Dell Seton Medical Center (2015-2018), Stephani L. Curry

Dissertations and Theses (Open Access)

Physical assaults are a major public health concern in the United States, with rates being on the rise during the last couple of years (WISQARS Nonfatal Injury Reports, n.d.). In Austin at the Dell Seton Medical Center [DSMC], physical assaults are a main reason for hospitalization, making up nearly 10% of their hospitalizations, with around 250 patients per year. No subgroup of the population is risk free from physical assaults; however, national data suggest some sociodemographic groups are at higher risk than others (“Injury and Violence Prevention”, n.d.). Given the diversity of Austin, TX, it was unclear whether local sociodemographic …

Epidemiology Of Tuberculosis In Internationally Displaced Children Resettling In Harris County, Gabriella S. Lamb

Dissertations and Theses (Open Access)

Background More than 300,000 refugees arrived in the United States (U.S.) from 2010-2015, and Texas accepts the 2nd highest number of refugees. Texas also accepts large numbers of asylees, parolees, and special immigrant visa holders. Additionally, a large proportion of trafficked persons in the U.S. live in or pass through Texas. Foreign-born children are disproportionately affected by tuberculosis (TB) and account for two-thirds of U.S. childhood TB cases. Children are at greater risk for progression from TB infection to disease and experience greater morbidity and mortality from TB disease. This makes screening for and treatment of TB infection in children …

Trends In Advanced Hiv Disease And Long-Term Outcomes Of Hivinfected Children Treated With Antiretroviral Therapy In Eastern And Southern Africa: 2003-2017, Peter James Elyanu

Dissertations and Theses (Open Access)

Despite the over 10-years’ experience providing pediatric antiretroviral therapy(ART) and implementing different WHO guidelines, data on updated trends (after 2010) in advanced disease at ART start, and on long-term survival of children receiving ART are scarce. Without these data, the impact of recent WHO guidelines on early treatment initiation and long-term survival remains unclear. First, we examined trends in advanced disease at ART start, then described 10-year survival and investigated risk factors of early mortality in children treated with ART and lastly examined the association between rapid ART initiation and outcomes (mortality and loss to follow-up) of HIV infected. We …


Cost-Effectiveness Of Collegiate Recovery Programs, Sierra Castedo De Martell May 2019

Cost-Effectiveness Of Collegiate Recovery Programs, Sierra Castedo De Martell

Dissertations and Theses (Open Access)

The prevalence of substance use disorders (SUDs) is greater among full-time college students and young adults regardless of enrollment status than it is among any other age group (1,2). These disorders represent substantial costs to both society and to institutions of higher education, both in terms of life years lost and in lost tuition revenue. The recent proliferation of collegiate recovery programs (CRPs) – supportive communities and resource centers for students seeking to maintain SUD recovery while pursuing a higher education – have the potential to help ameliorate some of these costs. While these CRPs are typically low-cost compared to …

Diagnostic Coding Of Physical Abuse Among Patients Evaluated By A Multidisciplinary Child Protection Team In A Pediatric Level I Trauma Center, Holly Hughes Garza

Dissertations and Theses (Open Access)

Child abuse is a substantial public health problem. Numerous studies have used hospital discharge data coded using the International Classification of Diseases, 9th and 10th Editions, Clinical Modification (ICD-9 and ICD-10) to identify cases of physical abuse seen in hospitals. Published studies on the sensitivity and specificity of ICD coding for physical child abuse are limited using ICD-9, and non-existent with ICD-10. This study examined the accuracy of ICD coding for physical child abuse, among patients less than 18 years of age, who were evaluated due to concern for physical abuse by a Multidisciplinary Child Protection Team (MCPT) during 2012-2013 …

The Prevalence Of Practicing Safety Professionals’ Knowledge, Involvement, And Competency Associated With Workplace Wellness Programs: Gauging The Safety Profession’S Engagement With The Total Worker Health Initiative, Jennifer C. Laine

Dissertations and Theses (Open Access)

The morbidity and mortality burden of occupational injuries and illnesses in the United States became such a public health concern that in 1970 the Occupational Safety and Health Act was signed into law. This law requires employers to provide workplaces “free from recognized hazards” and spurred the development of specific regulations along with the creation of academic and professional training programs to educate individuals about the safety sciences and careers in safety fields. Today there are an estimated 26,000 professionally trained and board certified safety professionals supporting workplace programs across the country, alongside numerous non-certified, but degreed, practicing safety professionals. …


Predictors Of On-Treatment Mortality Of Patients Undergoing Palliative Radiation Therapy: Improving The Quality Of End-Oflife Cancer Care, Matthew Stephen Ning May 2019

Predictors Of On-Treatment Mortality Of Patients Undergoing Palliative Radiation Therapy: Improving The Quality Of End-Oflife Cancer Care, Matthew Stephen Ning

Dissertations and Theses (Open Access)

PURPOSE: Excessive medical treatment at end-of-life is an indicator of poor quality care. While radiation therapy (RT) is effective for palliation, some patients die shortly after or even during treatment. Any treatment that requires terminal patients to spend significant time in the hospital setting contradicts palliative goals. This study investigates patterns of end-of-life RT to inform quality improvement initiatives.

METHODS: All patients who died within 6 months of starting RT at a single large academic cancer center between 2015 through 2018 were identified through our institutional databases on an Institutional Review Board-approved protocol. Clinical factors including age, treatment service, number …

Social Capital And Health Services Utilization In Msm, Edward Tsai May 2019

Social Capital And Health Services Utilization In Msm, Edward Tsai

Dissertations and Theses (Open Access)

While incidence of HIV has decreased overall and in most population subgroups, men who have sex with men (MSM) continue to remain at disproportional risk for new infection. In particular, MSM of color experience HIV incidence rates that continue to rise and represent the overwhelming majority of new cases each year. Evidence suggests greater risk among MSM may not be attributable primarily to individual behavioral level factors, but instead to structural and social environmental level factors such as access to health services. Access to health services represents a critical link in HIV and STI prevention, as health services provide serological …

Understanding A Physician’S Role In Combating The Anti-Vaccination Movement: A Retrospective Analysis Using 2014-2019 Data, Alisa C. Kim

PCOM Capstone Projects

Childhood vaccination has been one of public health’s greatest achievements in its history. Just over the past 20 years, immunizations averted more than 21 million hospitalizations and 732,000 deaths in the US (Skinner, 2017). However, healthcare professionals, public health advocates, and researchers are still witnessing an unceasing tension between the anti-vaccination movement and pro-vaccination organizations. Since the invention of the first vaccines, individuals from various religious sects, cultural backgrounds, and ethnic groups have been questioning the efficacy of vaccines, the possible health risks and side effects that may be introduced, and the morality behind the act of vaccinating. With questionable …

Faculty Publications

Researchers investigating relationships between the neighbourhood environment and health first need to decide on the spatial extent of the neighbourhood they are interested in. This decision is an important and ongoing methodological challenge since different methods of defining and delineating neighbourhood boundaries can produce different results. This paper explores this issue in the context of a New Zealand-based study of the relationship between the built environment and multiple measures of physical activity. Geographic information systems were used to measure three built environment attributes—dwelling density, street connectivity, and neighbourhood destination accessibility—using seven different neighbourhood definitions (three administrative unit boundaries, and 500, …

Pediatric Malnutrition: A Global Health Threat, Anja Wutz

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Pediatric malnutrition is a major cause of morbidity and mortality in developing nations. In Ghana, one-third of childhood deaths are attributable to it. The most common forms of severe acute malnutrition include kwashiorkor (protein deficiency), marasmus (overall energy deficiency), and various micronutrient deficiencies (iodine, vitamin A, zinc, iron). Thirteen percent of Ghanaian children are moderately or severely underweight, 23% are stunted, and 6 % are wasted due to malnutrition. Princess Marie Louise Children’s Hospital (PML) is the largest facility in the greater Accra region for managing cases of pediatric severe acute malnutrition (SAM). Current public health guidelines to reduce disability …


Food Pantry Evaluation And Assessment At The Dominican University Of California, Damian Cortez May 2019

Food Pantry Evaluation And Assessment At The Dominican University Of California, Damian Cortez

Senior Theses

Food security continues to be a relevant and prevalent problem in the US that affects millions of people per year (1). In 2016, 12.3% of American households were food insecure. Although the percentage of food insecure households is experiencing a downward trend since the great recession in 2007, the current percentage is still higher than the percent of food insecure households before the recession (1).

Research shows that food insecurity is an indicator for negative health, academic, and social outcomes among elementary children leading to poor mathematical and reading performance, weight gain, and poor social development (2). The negative health …


Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre May 2019

Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre

Honors Scholar Theses

Abnormal ocular motility is a common manifestation of many underlying pathologies particularly those that are neurological. Dynamics of saccades, when the eye rapidly changes its point of fixation, have been characterized for many neurological disorders including concussions, traumatic brain injuries (TBI), and Parkinson’s disease. However, widespread saccade analysis for diagnostic and research purposes requires the recognition of certain eye movement parameters. Key information such as velocity and duration must be determined from data based on a wide set of patients’ characteristics that may range in eye shapes and iris, hair and skin pigmentation [36]. Previous work on saccade analysis has …


Feedforward And Feedback Signals In The Olfactory System, Srimoy Chakraborty May 2019

Feedforward And Feedback Signals In The Olfactory System, Srimoy Chakraborty

Graduate Theses and Dissertations

The conglomeration of myriad activities in neural systems often results in prominent oscillations. The primary goal of the research presented in this thesis was to study effects of sensory stimulus on the olfactory system of rats, focusing on the olfactory bulb (OB) and the anterior piriform cortex (aPC). Extracellular electrophysiological measurements revealed distinct frequency bands of oscillations in OB and aPC. However, how these oscillatory fluctuations help the animal to process sensory input is not clearly understood. Here we show high frequency oscillations in olfactory bulb carry feedforward signals to anterior piriform cortex whereas feedback from the aPC is predominantly …


Reducing The Risk: Psychological And Technological Approaches For Improving Handwashing Practices In The Foodservice Industry, Jeffrey Allan Clark May 2019

Reducing The Risk: Psychological And Technological Approaches For Improving Handwashing Practices In The Foodservice Industry, Jeffrey Allan Clark

Graduate Theses and Dissertations

As Americans are spending greater portions of their dollar on food consumed outside the home, the foodservice industry plays more of an integral part of daily existence compared to previous generations. Given the numerous annual foodborne illness outbreaks that threaten human lives while undermining confidence in the food supply, food safety is a pertinent issue for industry stakeholders, government regulators, and consumers. Food worker handwashing reduces the risk of foodborne illness transmission, yet compliance with this simple behavior is a complex problem. This dissertation addresses, predominantly, the issue of sub-optimal handwashing practices through applying psychology and technology, including wearable computers …
