Objectives
To describe characteristics of ambulatory care visits for adults ≥ 65 years old and investigate differences in prescribing of new medications between patients with and without dementia.

Methods
We conducted a population-based cross-sectional study using the 2016 National Ambulatory Medical Care Survey (NAMCS) in the US. Non-perioperative ambulatory care visits of patients ≥ 65 years old with sampling weights were used to provide national estimates of visits. Baseline characteristics were compared between visits for patients …

“I’M Not Staying In The Hospital Tonight”: How Emergency Departments Can Leverage Health And Social Services At Home To Support Care Transitions For Older Patients, Emily Franzosa, Ula Hwang, Maya Genovesi, Orna Intrator, Thomas Edes, Michael Malone

Journal of Geriatric Emergency Medicine

When hospital admission is less than desirable and sending a patient home alone feels unsafe, connecting patients to health and social services at home are a valuable third option for emergency providers. Coordinating home support services from the ED is effective care delivery and aligns with health systems’ goals of decreasing avoidable admissions, and developing capacity to assess and refer patients to home support from the ED is part of good emergency care. Change also doesn’t have to happen overnight. Taking small steps now to improve older patients' transitions to home can help EDs build toward high-quality, patient-centered care for …

A Preliminary Evaluation Of The Behavioral Gerontology Staff Training Protocols, Minyoung Kim

Masters Theses

Staff training in aging settings is integral to ensuring quality services, and such training has traditionally been conducted in person. With the COVID-19 outbreak, there is a need for innovative approaches to training that reduce exposure for trainers and staff. However, the efficacy of such an approach has not yet been demonstrated. To prevent the waste of staff resources at long-term care facilities, this study evaluates the efficacy of behavioral gerontology staff training protocols as a form of telehealth by utilizing graduate and undergraduate students as pilot participants. We use an additive concurrent multiple-probe design across participants to evaluate the …

An Overview Of Individualized Management Of Neuropsychiatric Symptoms In Dementia, Megan B. Knoll

Theses and Graduate Projects

Background: It is estimated that about 11% of adults 65 and older have dementia in the United States. Neuropsychiatric symptoms are common in the presentation of dementia. These symptoms often result in increased morbidity and mortality, negative patient outcomes, caregiver burden, institutionalized care, and diminished quality of life. The focus of this paper is to analyze the therapeutic effectiveness of nonpharmacologic interventions in the management of neuropsychiatric symptoms of dementia.

Methods: A literature review was conducted to critique current evidence on the use of nonpharmacologic interventions in managing neuropsychiatric symptoms in older adults with dementia. Searches were performed using PubMed, …

White Matter Hyperintensity Volume And Location: Associations With Wm Microstructure, Brain Iron, And Cerebral Perfusion, Christopher E. Bauer, Valentinos Zachariou, Elayna R. Seago, Brian T. Gold

Neuroscience Faculty Publications

Cerebral white matter hyperintensities (WMHs) represent macrostructural brain damage associated with various etiologies. However, the relative contributions of various etiologies to WMH volume, as assessed via different neuroimaging measures, is not well-understood. Here, we explored associations between three potential early markers of white matter hyperintensity volume. Specifically, the unique variance in total and regional WMH volumes accounted for by white matter microstructure, brain iron concentration and cerebral blood flow (CBF) was assessed. Regional volumes explored were periventricular and deep regions. Eighty healthy older adults (ages 60–86) were scanned at 3 Tesla MRI using fluid-attenuated inversion recovery, diffusion tensor imaging (DTI), …

The Detrimental Association Between Fear Of Falling And Motor Performance In Older Cancer Patients With Chemotherapy-Induced Peripheral Neuropathy, Gu Eon Kang, Tamiko K Murphy, Mark E Kunik, Hoda J Badr, Biruh T Workeneh, Sarvari V Yellapragada, Yvonne H Sada, Bijan Najafi

Faculty, Staff and Students Publications

BACKGROUND: Cancer patients with chemotherapy-induced peripheral neuropathy (CIPN) are at increased risk of falls and developing fear of falling (FoF). Although FoF may continue to impair motor performance and increase the risk of falling even further, this association remains unexplored in CIPN.

RESEARCH QUESTION: Does high FoF in patients with CIPN further deteriorate motor performance beyond the impairment from CIPN-related sensory deficits?

METHODS: In this secondary analysis of data collected from two clinical trials, gait parameters during habitual walking condition and postural sway parameters during 30-second quiet standing (eye-open and eyes-closed) were compared among older participants (≥ 65 years) with …

Analysis Of Genetic Variants Associated With Levels Of Immune Modulating Proteins For Impact On Alzheimer’S Disease Risk Reveal A Potential Role For Siglec14, Benjamin C. Shaw, Yuriko Katsumata, James F. Simpson, David W. Fardo, Steven Estus

Biostatistics Faculty Publications

Genome-wide association studies (GWAS) have identified immune-related genes as risk factors for Alzheimer’s disease (AD), including TREM2 and CD33, frequently passing a stringent false-discovery rate. These genes either encode or signal through immunomodulatory tyrosine-phosphorylated inhibitory motifs (ITIMs) or activation motifs (ITAMs) and govern processes critical to AD pathology, such as inflammation and amyloid phagocytosis. To investigate whether additional ITIM and ITAM-containing family members may contribute to AD risk and be overlooked due to the stringent multiple testing in GWAS, we combined protein quantitative trait loci (pQTL) data from a recent plasma proteomics study with AD associations in a recent …

Emergency Department - Community Partnership To Coordinate Older Adults Falls Prevention Programs, Suzanne Ryer, Ann Gallo, Adam Perry, Michael Malone

Journal of Geriatric Emergency Medicine

Abstract

Falls and injurious falls are common causes for emergency department visits in older adults. Prior literature describing ED care of older adults has focused on the patients' injuries and their ED care. There is a gap in the literature describing community- based falls prevention strategies and interventions deployed by community organizations, beyond health systems. We identified variation in approaches to older adults among paramedic programs from one community to the next within Milwaukee County, Wisconsin. We also noted no organized falls prevention program spanning all communities, emergency departments and health systems in the county. We describe the implementation of …

Healthy Dietary Intake Moderates The Effects Of Age On Brain Iron Concentration And Working Memory Performance, Valentinos Zachariou, Christopher E. Bauer, Elayna R. Seago, Georgia Panayiotou, Edward D. Hall, D. Allan Butterfield, Brian T. Gold

Neuroscience Faculty Publications

Age-related brain iron accumulation is linked with oxidative stress, neurodegeneration and cognitive decline. Certain nutrients can reduce brain iron concentration in animal models, however, this association is not well established in humans. Moreover, it remains unknown if nutrition can moderate the effects of age on brain iron concentration and/or cognition. Here, we explored these issues in a sample of 73 healthy older adults (61-86 years old), while controlling for several factors such as age, gender, years of education, physical fitness and alcohol-intake. Quantitative susceptibility mapping was used for assessment of brain iron concentration and participants performed an N-Back paradigm to …

Dysregulation Of Systemic Immunity In Aging And Dementia, Jenny Lutshumba, Barbara S. Nikolajczyk, Adam D. Bachstetter

Pharmacology and Nutritional Sciences Faculty Publications

Neuroinflammation and the tissue-resident innate immune cells, the microglia, respond and contribute to neurodegenerative pathology. Although microglia have been the focus of work linking neuroinflammation and associated dementias like Alzheimer’s Disease, the inflammatory milieu of brain is a conglomerate of cross-talk amongst microglia, systemic immune cells and soluble mediators like cytokines. Age-related changes in the inflammatory profile at the levels of both the brain and periphery are largely orchestrated by immune system cells. Strong evidence indicates that both innate and adaptive immune cells, the latter including T cells and B cells, contribute to chronic neuroinflammation and thus dementia. Neurodegenerative hallmarks …

INTRODUCTION: Analysis of sequence data in high-risk pedigrees is a powerful approach to detect rare predisposition variants.

METHODS: Rare, shared candidate predisposition variants were identified from exome sequencing 19 Alzheimer's disease (AD)-affected cousin pairs selected from high-risk pedigrees. Variants were further prioritized by risk association in various external datasets. Candidate variants emerging from these analyses were tested for co-segregation to additional affected relatives of the original sequenced pedigree members.

RESULTS: AD-affected high-risk cousin pairs contained 564 shared rare variants. Eleven variants spanning 10 genes were prioritized in external datasets: rs201665195 (ABCA7), and rs28933981 (TTR) were previously …

Inhibition of the protein phosphatase calcineurin (CN) ameliorates pathophysiologic and cognitive changes in aging rodents and mice with aging-related Alzheimer's disease (AD)-like pathology. However, concerns over adverse effects have slowed the transition of common CN-inhibiting drugs to the clinic for the treatment of AD and AD-related disorders. Targeting substrates of CN, like the nuclear factor of activated T cells (NFATs), has been suggested as an alternative, safer approach to CN inhibitors. However, small chemical inhibitors of NFATs have only rarely been described. Here, we investigate a newly developed neuroprotective hydroxyquinoline derivative (Q134R) that suppresses NFAT signaling, without inhibiting CN activity. …

Background

Muscle atrophy is a common pathology associated with disuse, such as prolonged bed rest or spaceflight, and is associated with detrimental health outcomes. There is emerging evidence that disuse atrophy may differentially affect males and females. Cellular mechanisms contributing to the development and progression of disuse remain elusive, particularly protein turnover cascades. The purpose of this study was to investigate the initial development and progression of disuse muscle atrophy in male and female mice using the well-established model of hindlimb unloading (HU).

Methods

One hundred C57BL/6J mice (50 male and 50 female) were hindlimb suspended for 0 (control), 24, …

Estimation Of Excess Mortality Rates Among Us Assisted Living Residents During The Covid-19 Pandemic., Kali S. Thomas, Wenhan Zhang, David M. Dosa, Paula Carder, Philip Sloane, Sheryl Zimmerman

Institute on Aging Publications

The devastating effects of COVID-19 among older adults residing in long-term care settings have been well documented.1 Although much attention has been paid to COVID-19–associated mortality in nursing homes,2 less is understood about its effects on assisted living residents. Most assisted living residents are aged 80 years or older and many have multiple chronic illnesses, making them highly susceptible to poor outcomes of COVID-19.3 This study examines the excess mortality among a US cohort of assisted living residents during the COVID-19 pandemic.

The purpose of this evidence-based project (EBP) is to improve the emergency department (E.D.) staff adherence in completing the Identifying Seniors at Risk (ISAR) screening tool. The specific aim is to improve electronic health record (EHR) data collection to enhance the identification of older adults that are frequent utilizers of the E.D. at a local community hospital in Southern California. Based upon the most recent National Hospital Ambulatory Medical Care Survey, patients ages 65 and older make up 32% of all E.D. admissions. These patients also represent 50% of the moderate to severely ill patients seen in the E.D. …

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 preferences, …

A Highly Predictive Microrna Panel For Determining Delayed Cerebral Vasospasm Risk Following Aneurysmal Subarachnoid Hemorrhage, Wang-Xia Wang, Joe E. Springer, Kevin Xie, David W. Fardo, Kevin W. Hatton

Sanders-Brown Center on Aging Faculty Publications

Approximately one-third of aneurysmal subarachnoid hemorrhage (aSAH) patients develop delayed cerebral vasospasm (DCV) 3–10 days after aneurysm rupture resulting in additional, permanent neurologic disability. Currently, no validated biomarker is available to determine the risk of DCV in aSAH patients. MicroRNAs (miRNAs) have been implicated in virtually all human diseases, including aSAH, and are found in extracellular biofluids including plasma and cerebrospinal fluid (CSF). We used a custom designed TaqMan Low Density Array miRNA panel to examine the levels of 47 selected brain and vasculature injury related miRNAs in CSF and plasma specimens collected from 31 patients with or without DCV …
