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. …

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.

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, …

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 …

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, …

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 screening for Dementia …

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 6, 2021. As the coronavirus (COVID-19) pandemic continues, it is important to understand why older adults are at higher risk for more severe morbidity and higher mortality compared to younger age groups. At the same time, there is a growing body of evidence suggesting physical activity and exercise can have positive benefits for older adults’ health. Point of application #1: The first step in keeping older adults active is motivating them to adhere to a structured program either at home, in a community setting, or in a long-term care …

Alzheimer's Patients’ Mental Health During The Covid 19 Pandemic, Maryanna Schweininger, Yvonne Maduka, Ajh'shana Collins

Rowan-Virtua Research Day

Alzheimer’s disease (AD) is a degenerative brain disease caused by β Amyloid plaques and neurofibrillary tangles, which results in memory loss and cognitive decline. It is the sixth leading cause of death in the United States. Approximately 50% of those with AD experience some degree of depression during the course of the disease, which has been shown to accelerate functional decline, institutionalization, and even mortality.

Many who cannot care for themselves live in an assisted living facility or retirement home. Since the beginning of the COVID 19 pandemic, people have been urged to social distance in order to decrease the …

Bilateral Lower Extremity Ischemia Following Cardiac Catheterization, Moses Avedikian, Alan Lucerna, Trent Malcolm

Rowan-Virtua Research Day

Acute limb ischemia is a rare yet limb-threatening presentation where rapid diagnosis and intervention is warranted. Bilateral lower extremity ischemia can be a rare complication following procedures, such as a cardiac catheterization with access obtained in the groin. We describe a case of a 79-year-old female who presented with bilateral lower extremity ischemia following a cardiac catheterization 2 weeks prior. The patient underwent CT angiography, which demonstrated occlusion with no contrast present in the bilateral femoral arteries.

Water Exchange Rate Across The Blood-Brain Barrier Is Associated With Csf Amyloid-Β 42 In Healthy Older Adults, Brian T. Gold, Xingfeng Shao, Tiffany L. Sudduth, Gregory A. Jicha, Donna M. Wilcock, Elayna R. Seago, Danny J. J. Wang

Sanders-Brown Center on Aging Faculty Publications

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 (k_w). 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 CSF amyloid …

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

Spring 2021 Virtual OTD Capstone Symposium

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 adults …

A Descriptive Study Of Health-Related Risks And Outcome Differences By Loneliness Status In A Sample Of Older Veterans, Rachael Beard

Dissertations

There is a need to understand the influences and outcomes related to loneliness in veterans living with complex illness. Patients require self-care to manage complications and exacerbations associated with complex illness. Deficits in self-care result in negative health outcomes and drive resource utilization upward. The identification of potential factors related to self-care is important. Loneliness may be one factor that influences patients’ ability and desire to care for themselves. Descriptive correlational design was used to evaluate loneliness both as a predictor and outcome in veterans admitted to the hospital for three complex respiratory illnesses (heart failure, chronic obstructive pulmonary disease, …

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

Spring 2021 Virtual OTD Capstone Symposium

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 …
