Post-Acquisition Processing Confounds In Brain Volumetric Quantification Of White Matter Hyperintensities, Ahmed A. Bahrani, Omar M. Al-Janabi, Erin L. Abner, Shoshana H. Bardach, Richard J. Kryscio, Donna M. Wilcock, Charles D. Smith, Gregory A. Jicha

Neurology Faculty Publications

BACKGROUND: Disparate research sites using identical or near-identical magnetic resonance imaging (MRI) acquisition techniques often produce results that demonstrate significant variability regarding volumetric quantification of white matter hyperintensities (WMH) in the aging population. The sources of such variability have not previously been fully explored.

NEW METHOD: 3D FLAIR sequences from a group of randomly selected aged subjects were analyzed to identify sources-of-variability in post-acquisition processing that can be problematic when comparing WMH volumetric data across disparate sites. The methods developed focused on standardizing post-acquisition protocol processing methods to develop a protocol with less than 0.5% inter-rater variance.

RESULTS: A series …

The Effect Of Viewing Advertisements Depicting Information And Communication Technology On Older Adults' Technology Self-Efficacy, Hollie Brianne Coleman

Masters Theses & Specialist Projects

Information and communication technologies (ICTs) are an important part of society today. Older adults often report ICTs as difficult to use and unhelpful; however, ICTs can support older adults’ ability to stay in touch with family and friends across long distances and help increase their quality of life. Unfortunately, training programs targeted at teaching older adults to use ICTs are often costly and time-consuming. The current study attempts to determine whether advertisements depicting older adults using ICTs can be used to increase self-efficacy without the use of training programs.

A within subjects experimental design was completed using an independent variable …

Thirty-Five Years Of Computerized Cognitive Assessment Of Aging — Where Are We Now?, Avital Sternin, Alistair Burns, Adrian M. Owen

Brain and Mind Institute Researchers' Publications

Over the past 35 years, the proliferation of technology and the advent of the internet have resulted in many reliable and easy to administer batteries for assessing cognitive function. These approaches have great potential for affecting how the health care system monitors and screens for cognitive changes in the aging population. Here, we review these new technologies with a specific emphasis on what they offer over and above traditional ‘paper-and-pencil’ approaches to assessing cognitive function. Key advantages include fully automated administration and scoring, the interpretation of individual scores within the context of thousands of normative data points, the inclusion of …

Home-Based Cognitive Monitoring: The Role Of Personality And Predictors Of Adherence And Satisfaction, Nasreen A. Sadeq

USF Tampa Graduate Theses and Dissertations

Over the last several decades, a growing awareness of the benefits of regular screening for common health conditions, such as cancer and cardiovascular diseases, has paved the way for preventative screenings to become routine in medical settings. Given that cognitive impairment is frequently reported as the number one worry of older adults, home-based cognitive monitoring may be an innovative solution that allows middle aged and older adults to take an active role in monitoring an important aspect of their health. Although several home-based cognitive monitoring programs have been validated for use in clinical and home-based settings, the Cogstate Brief Battery …

Neverland: A Critical Autoethnography Of Aging With Cystic Fibrosis, Alexandra Ch Nowakowski

The Qualitative Report

In this autoethnography, I analyze stereotypes and misconceptions about people with cystic fibrosis (CF). I examine these illness representations and their social underpinnings through critical analysis of my journey to conclusive diagnosis with CF after first being tested for the disease in early life, and the events that have followed from that turning point. Using experiential data and prior research, I explore and refute harmful misconceptions about life with CF. I challenge the notion that people with CF never grow old. I also contest the idea that people who receive conclusive diagnoses during adulthood only then transition into patient identities. …

The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke

Faculty and Student Publications

© Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) …

Memory-Based Viewing: A Potential Marker Of Pathological Aging, Jenna Blujus

Theses and Dissertations

Markers of cognitive impairment are needed to distinguish normal from pathological aging prior to the onset of clinical symptomology to improve Alzheimer’s disease (AD) treatment or prevention efforts. AD pathology is believed to develop years or even decades prior to diagnosis in medial temporal lobe subregions that provide input to the hippocampus (Braak & Braak, 1991), disrupting the ability of the hippocampus to bind individual elements of an experience to form cohesive memory representations. Eye movement behavior is a sensitive index of learning and effects of memory on eye movements have been shown to emerge rapidly (within 500-750ms of stimuli …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

Moderating Effect Of Cortical Thickness On Bold Signal Variability Age-Related Changes, Daiana R. Pur, Roy A. Eagleson, Anik De Ribaupierre, Nathalie Mella, Sandrine De Ribaupierre

Brain and Mind Institute Researchers' Publications

© Copyright © 2019 Pur, Eagleson, de Ribaupierre, Mella and de Ribaupierre. The time course of neuroanatomical structural and functional measures across the lifespan is commonly reported in association with aging. Blood oxygen-level dependent signal variability, estimated using the standard deviation of the signal, or “BOLDSD,” is an emerging metric of variability in neural processing, and has been shown to be positively correlated with cognitive flexibility. Generally, BOLDSD is reported to decrease with aging, and is thought to reflect age-related cognitive decline. Additionally, it is well established that normative aging is associated with structural changes in brain regions, and that …

Short-Run Health Consequences Of Retirement And Pension Benefits: Evidence From China, Plamen Nikolov, Alan Adelman

Justice & Well-Being Studies Faculty Scholarship

This paper examines the impact of the New Rural Pension Scheme (NRPS) in China. Exploiting the staggered implementation of an NRPS policy expansion that began in 2009, we used a difference-in-difference approach to study the effects of the introduction of pension benefits on the health status, health behaviors, and healthcare utilization of rural Chinese adults age 60 and above. The results point to three main conclusions. First, in addition to improvements in self-reported health, older adults with access to the pension program experienced significant improvements in several important measures of health, including mobility, self-care, usual activities, and vision. Second, regarding …

Exploring The Challenges Non-Clinical Departments Encounter During Eden Alternative Implementation, Keith George

Walden Dissertations and Doctoral Studies

The Centers for Medicare and Medicaid Services recommends new guidelines that shift healthcare delivery in nursing homes and long-term care facilities from an institutional model to a person-centered care model. Although clinical outcomes are measured and tracked, there was limited literature about the challenges non-clinical departments face in a nursing facility during implementation of a person-centered model. The purpose of this qualitative study was to explore the challenges non-clinical staff experience while transitioning to an Eden Alternative philosophy, a person-centered care model. The theoretical foundation of this study relied upon Bressers' Contextual Interaction Theory. The research questions for this study …

From Sunrise To Sunset: A Lifespan Approach To Understanding The Mental Health Of A Subset Of American Farmers, Janna L. Imel

Theses and Dissertations

Prior research has indicated higher risk of suicide for farmers and identified depression and anxiety as mental health concerns, though the majority of research was conducted in the 1980s-1990s. In today’s economic, social, and political climate, farmers are exposed to situations and stressors reminiscent of the 1980s Farm Crisis. An added risk is the aging workforce of farmers, as age-related conditions can make farming even riskier. This study investigated the mental health of a subset of American farmers by exploring farm-related stressors, coping mechanisms, and mental health outcomes. Dispositional mindfulness was explored as a specific coping mechanism. Participants (N …

Implicit Attitudes Of Asian American Older Adults Toward Aging, Anita Ho

Scripps Senior Theses

Greenwald, McGhee, and Schwartz (1998) developed the Implicit Association Test (IAT), a measure of mental associations between target pairs and positive or negative attributes. Highly associative categories yield faster responses than the reverse mental associations, which is thought to reflect implicit attitudes toward stereotypes. The present study investigated the effect of ethnic group on one’s implicit attitudes toward aging and gender stereotypes by comparing two groups of older adults, Asian Americans and Caucasian Americans, that likely hold different culture values. Past qualitative studies have established the existence of mental health stigma in Asian American populations, including negative Asian American perceptions …

Unmet Support Needs Of Informal Caregivers Of Older Adults, Julie Ann Smith Hinders

Walden Dissertations and Doctoral Studies

Due to projected growth of the 65-and-older population and concerns of an impending care gap, reliance on informal caregivers is expected to increase. Improving support for informal caregivers is viewed as a national priority, yet research related to the unmet support needs of informal caregivers is limited. The purpose of this cross-sectional correlational study was to examine predictive relationships between contextual factors (caregiving relationship and type of illness) and environmental factors (rurality) and the unmet support needs (classes, service access, support groups, counseling, and respite) of informal caregivers of older adults. The theoretical framework was Bronfenbrenner's ecological systems theory. Archival …
