Understanding Older Adults Living In Medically Underserved Areas Perspectives Regarding Type 2 Diabetes Care Received, Christopher Rogers

Seton Hall University Dissertations and Theses (ETDs)

Older adults with type 2 diabetes living in medically underserved areas (MUAs) have unique health and social needs that must be taken into consideration when supporting their type 2 diabetes treatment and management care. Effective treatment and management of type 2 diabetes for older adults living in MUAs requires incorporating the preferences, desires, needs, values, and goals of the person at the center of the care into his/her care plan. Shifting care to be conducive to the treatment and management goals and plans co-created with older adults living in MUAs based on their individual physical, psychological, social, and spiritual ...

Brain myeloid cells, include infiltrating macrophages and resident microglia, play an essential role in responding to and inducing neurodegenerative diseases, such as Alzheimer’s disease (AD). Genome-wide association studies (GWAS) implicate many AD casual and risk genes enriched in brain myeloid cells. Coordinated arginine metabolism through arginase 1 (Arg1) is critical for brain myeloid cells to perform biological functions, whereas dysregulated arginine metabolism disrupts them. Altered arginine metabolism is proposed as a new biomarker pathway for AD. We previously reported Arg1 deficiency in myeloid biased cells using lysozyme M (LysM) promoter-driven deletion worsened amyloidosis-related neuropathology and behavioral impairment. However, it ...


Rule Out Screening For Undiagnosed Dementia And Alzheimer’S Disease Using An Ehr Based Machine Learning Solution, Branum Stephan, David A. Julovich, Dustin Bracy, Jeff Nguyen 2021 Southern Methodist University

Rule Out Screening For Undiagnosed Dementia And Alzheimer’S Disease Using An Ehr Based Machine Learning Solution, Branum Stephan, David A. Julovich, Dustin Bracy, Jeff Nguyen

SMU Data Science Review

Abstract. Current detection methods for Dementia and Alzheimer’s disease include cerebral spinal fluid (CSF) markers and/or the use of positron emission tomography (PET) imaging, both being high-cost, highly invasive testing methods. The need for low-cost, minimally invasive methods to prescreen individuals for cognitive impairment has been a challenge for many years. Today’s costs associated with an annual screen for all adults 65 and above using current methods (CSF, PET) reach well beyond trillions of dollars per year. Motivated by the limited accessibly and high costs, an alternative tool presented within this paper demonstrates an effective rule out ...

INTRODUCTION: We tested if water exchange across the blood-brain barrier (BBB), estimated with a noninvasive magnetic resonance imaging (MRI) technique, is associated with cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) and neuropsychological function.

METHODS: Forty cognitively normal older adults (67–86 years old) were scanned with diffusion‐prepared, arterial spin labeling (DP‐ASL), which estimates water exchange rate across the BBB (kw). Participants also underwent CSF draw and neuropsychological testing. Multiple linear regression models were run with kw as a predictor of CSF concentrations and neuropsychological scores.

RESULTS: In multiple brain regions, BBB kw was positively associated ...

With improved healthcare, the Down syndrome (DS) population is both growing and aging rapidly. However, with longevity comes a very high risk of Alzheimer’s disease (AD). The LIFE-DSR study (NCT04149197) is a longitudinal natural history study recruiting 270 adults with DS over the age of 25. The study is designed to characterize trajectories of change in DS-associated AD (DS-AD). The current study reports its cross-sectional analysis of the first 90 subjects enrolled. Plasma biomarkers phosphorylated tau protein (p-tau), neurofilament light chain (NfL), amyloid β peptides (Aβ1-40, Aβ1-42), and glial fibrillary acidic protein (GFAP) were undertaken with previously ...

Understanding Successful Aging For Well-Elderly Adults Through Leisure And Social Participation, May Rose Lazarte, Karen Park, Becki Cohill, Susan Macdermott

Virtual OTD Capstone Symposium, Spring 2021

The Centers for Disease Control and Prevention (CDC) reported by the year 2050, about 26% of the population would be 60 years of age or older (CDC, 2020). As Baby Boomers (individuals born between 1946-1964) enter the Third Age, defined by lifestyle choice, consumption, and preservation of youthfulness, more and more individuals are given the opportunity to age in place and participate in new/refined lifestyles (Hostetler, 2011). Although, research has proven older adults, who are now in their later years in life, are prone to experience social isolation, loneliness, depression, anxiety, and social stressors (Valtorta et al., 2018). Older ...

Incorporating Reminiscence Therapy Into Traditional Ot Practice For Adults With Adrd Residing In A Snf/Ltc, Natasha Menard, Becki Cohill, Susan Macdermott, Karen Park

Virtual OTD Capstone Symposium, Spring 2021

As the population diagnosed with Alzheimer’s disease and related dementias (ADRD) raises from 5.3 to 12.7 million over the next three decades, this calls for a demand for treatments to address this population (Alzheimer’s Association, 2021; Atchinson & Dirette, 2017). While traditional practice often focuses on symptom management, the inclusion of functional activities alone does not fully address the negative side effects of ADRD (Kok et al., 2013; Lepore et al., 2017; Mayo Clinic, 2019). Both occupational therapy (OT) and reminiscence therapy have been shown to be effective methods to treat the ADRD population separately, but there is limited evidence currently demonstrating the benefits of the combined approach. This study aimed to address this gap by completing a needs assessment and developing a resulting program.

There were ...


Support For Family Members Who Are Caregivers To Relatives With Acquired Brain Injury, Janet Walker, Lourens Schlebusch, Bernhard Gaede 2021 UNIVERSITY OF KWAZULU-NATAL, DEPARTMENT OF FAMILY MEDICINE, DURBAN, SOUTH AFRICA

Support For Family Members Who Are Caregivers To Relatives With Acquired Brain Injury, Janet Walker, Lourens Schlebusch, Bernhard Gaede

Journal of Mind and Medical Sciences

Objectives. Family members caring for a patient with acquired brain injury (ABI) are coping with inordinate levels of stress partially due to their lack of understanding of the neuropsychological effects of acquired brain injury in the patient. The objective of this research is to show that as the caregivers’ stress levels increase, there is an increase in suicidal ideation. This highlights the causal relationship between unhealthy stress and reduced psychological well-being in these caregivers. In addition, qualitative research evidence regarding the caregivers’ views of their main sources of stress are presented. Methods. The participants were a random sample of 80 ...

Social Engagement Of Nursing Home Residents: A Comparison Of Two Observation Methods, Annika Gabbard

Masters Theses & Specialist Projects

In Kentucky, low levels of physical activity and social engagement negatively impact health. This problem led to the creation of Bingocize®, an exercise program that combines the game of Bingo with intermittent exercises in a group setting to increase levels of positive affect, physical health, and, the focus of this study, social engagement. Since clear benefits of social engagement have been established, measurement and documentation of this behavior can assist in determining the level of potential benefit from Bingocize®. The purpose of this study was to compare the opinions of healthcare workers who have experience with Bingocize® on two measures ...

Improving Caregivers’ Perceived Involvement In Care Through Facilitating Communication With Hospital Providers, Heather Manolas

Student Scholarly Projects

Practice Problem: Involvement of family in care-planning for prevention of delirium in acute care settings is crucial, yet remains underutilized in those who are cognitively impaired. Despite the incidence of delirium in acute care worsening during COVID-19, many factors have led to it being placed on the back burner.

PICOT: In caregivers of cognitively impaired individuals, can implementation of an evidence-based, best practice tool that advocates for evidence-based delirium prevention strategies tailored to their loved-one and facilitates family involvement in care planning for these strategies during a healthcare experience as compared to no other intervention improve confidence in, and involvement ...

Clostridioides difficile disproportionally affects the elderly living in nursing homes (NHs). Our objective was to explore the prevalence of C. difficile in NH elders, over time and to determine whether the microbiome or other clinical factors are associated with C. difficile colonization. We collected serial stool samples from NH residents. C. difficile prevalence was determined by quantitative polymerase-chain reaction detection of Toxin genes tcdA and tcdB; microbiome composition was determined by shotgun metagenomic sequencing. We used mixed-effect random forest modeling machine to determine bacterial taxa whose abundance is associated with C. difficile prevalence while controlling for clinical covariates including demographics ...

Astrocytes with intracellular accumulations of misfolded phosphorylated tau protein have been observed in advanced-stage chronic traumatic encephalopathy (CTE) and in other neurodegenerative conditions. There is a growing awareness that astrocytic tau inclusions are also relatively common in the brains of persons over 70 years of age-affecting approximately one-third of autopsied individuals. The pathologic hallmarks of aging-related tau astrogliopathy (ARTAG) include phosphorylated tau protein within thorn-shaped astrocytes (TSA) in subpial, subependymal, perivascular, and white matter regions, whereas granular-fuzzy astrocytes are often seen in gray matter. CTE and ARTAG share molecular and histopathologic characteristics, suggesting that trauma-related mechanism(s) may predispose to ...

Protecting P-Glycoprotein At The Blood-Brain Barrier From Degradation In An Alzheimer's Disease Mouse Model, Yujie Ding, Yu Zhong, Andrea Baldeshwiler, Erin L. Abner, Björn Bauer, Anika M. S. Hartz

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Failure to clear Aβ from the brain is partly responsible for Aβ brain accumulation in Alzheimer's disease (AD). A critical protein for clearing Aβ across the blood-brain barrier is the efflux transporter P-glycoprotein (P-gp). In AD, P-gp levels are reduced, which contributes to impaired Aβ brain clearance. However, the mechanism responsible for decreased P-gp levels is poorly understood and there are no strategies available to protect P-gp. We previously demonstrated in isolated brain capillaries ex vivo that human Aβ40 (hAβ40) triggers P-gp degradation by activating the ubiquitin-proteasome pathway. In this pathway, hAβ40 initiates P-gp ubiquitination, leading to internalization ...
