Characterization of the genetic landscape of Alzheimer’s disease (AD) and related dementias (ADD) provides a unique opportunity for a better understanding of the associated pathophysiological processes. We performed a two-stage genome-wide association study totaling 111,326 clinically diagnosed/‘proxy’ AD cases and 677,663 controls. We found 75 risk loci, of which 42 were new at the time of analysis. Pathway enrichment analyses confirmed the involvement of amyloid/tau pathways and highlighted microglia implication. Gene prioritization in the new loci identified 31 genes that were suggestive of new genetically associated processes, including the tumor necrosis factor alpha pathway through the linear ubiquitin chain assembly …

Does Age-Related Macular Degeneration (Amd) Treatment Influence Patient Falls And Mobility? A Systematic Review., Hannah Garrigan, Jacquelyn N. Hamati, Parth Lalakia, Rosemary Frasso, Brooke Salzman, Leslie Hyman

Alzheimer's And Patient Caregiver Burnout: A Review Of The Literature, Madeline Hekeler

James Madison Undergraduate Research Journal (JMURJ)

The term “silent epidemic” is fitting for Alzheimer’s disease (AD), as its negative impact is widely felt but rarely discussed. Burnout among AD caregivers has become an epidemic of its own as caregivers experience an increase in health risks, stress, and financial burden. This literature review focuses on caregiver burnout and how imperative it is that caregivers are better supported in their role. Researchers have developed instruments to assess and intervene in caregiver burnout that have shown effectiveness among caregivers and their families.Nevertheless, further longitudinal research is warranted regarding more effective interventions, including stress management and social support mechanisms.

Level Of Comfort In Evaluating Older Patients Amongst Medical Students And Emergency Medicine Residents, Lily L. Berrin, Phraewa Thatphet, Anita N. Chary, Surriya C. Ahmad, Don Melady, Shan W. Liu

Journal of Geriatric Emergency Medicine

Introduction

As the population ages, emergency physicians must be better equipped to manage the complex needs of older patients. While geriatric core competencies have been developed for medical students and emergency medicine (EM) residents, little work has been done to evaluate EM trainees’ comfort with these competencies, or their interest in and barriers to learning more about Geriatric Emergency Medicine (GEM).

Methods

We conducted a cross-sectional study of EM residents and medical students in their clinical years of training with interest in EM. We used an online self-administered survey to evaluate trainees’ self-reported comfort with previously reported geriatric competency domains, …

Covid-19 In Older Adults- A Practical Review For Emergency Providers In 2022, Michael L. Malone, Teresita Hogan, Alice Bonner, Kevin Biese, Patti Pagel, Kathleen Unroe

Journal of Geriatric Emergency Medicine

COVID-19 has posed a considerable threat to all aspects of older Americans’ lives. The pandemic generated acute illness, emergency department (ED) visits, hospitalization, respiratory failure, and death. Pandemic-associated social isolation and loneliness further endangered older adults. Recovery from COVID-19 illness has commonly been followed by chronic symptoms, which may also precipitate ED visits. While vaccination has mitigated risks of serious illness requiring hospitalization, a booster dose is required to sustain protection. New treatments and therapies, including monoclonal antibodies and antiviral agents, have shown efficacy for older adults who are at risk of hospitalization. Older adults remain vulnerable in 2022, after …

Alzheimer’s disease (AD) is defined by amyloid (A) and tau (T) pathologies, with T better correlated to neurodegeneration (N). However, T and N have complex regional relationships in part related to non-AD factors that influence N. With machine learning, we assessed heterogeneity in ¹⁸F-flortaucipir vs. ¹⁸F-fluorodeoxyglucose positron emission tomography as markers of T and neuronal hypometabolism (N_M) in 289 symptomatic patients from the Alzheimer’s Disease Neuroimaging Initiative. We identified six T/N_M clusters with differing limbic and cortical patterns. The canonical group was defined as the T/N_M pattern with lowest regression residuals. Groups resilient to …

Alzheimer’s disease (AD) is a genetically complex disease for which nearly 40 loci have now been identified via genome-wide association studies (GWAS). We attempted to identify groups of rare variants (alternate allele frequency <0.01) associated with AD in a region-based, whole-genome sequencing (WGS) association study (rvGWAS) of two independent AD family datasets (NIMH/NIA; 2247 individuals; 605 families). Employing a sliding window approach across the genome, we identified several regions that achieved association p values <10⁻⁶, using the burden test or the SKAT statistic. The genomic region around the dystobrevin beta (DTNB) gene was identified with the burden and SKAT test and replicated in case/control samples from the ADSP study reaching genome-wide significance after meta-analysis (p_meta= 4.74 × 10⁻⁸ ). SKAT analysis also revealed region-based association around the Discs large homolog 2 (DLG2) …

Physical Therapy Faculty Research

Introduction The Healthy Ageing and Intellectual Disability (HA-ID) study is a prospective multicentre cohort study in the Netherlands that started in 2008, including 1050 older adults (aged ≥50) with intellectual disabilities (ID). The study is designed to learn more about the health and health risks of this group as they age. Compared with the amount of research in the general population, epidemiological research into the health of older adults with ID is still in its infancy. Longitudinal data about the health of this vulnerable and relatively unhealthy group are needed so that policy and care can be prioritised and for …

Lu, Alan Daugherty

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: The ascending aorta is a common location for aneurysm and dissection. This aortic region is populated by a mosaic of medial and adventitial cells that are embryonically derived from either the second heart field (SHF) or the cardiac neural crest. SHF-derived cells populate areas that coincide with the spatial specificity of thoracic aortopathies. The purpose of this study was to determine whether and how SHF-derived cells contribute to ascending aortopathies.

METHODS: Ascending aortic pathologies were examined in patients with sporadic thoracic aortopathies and angiotensin II (AngII)–infused mice. Ascending aortas without overt pathology from AngII-infused mice were subjected …

Sanders-Brown Center on Aging Faculty Publications

Background and Objectives Little is known about the effect of education or other indicators of cognitive reserve on the rate of reversion from mild cognitive impairment (MCI) to normal cognition (NC) or the relative rate (RR) of reversion from MCI to NC vs progression from MCI to dementia. Our objectives were to (1) estimate transition rates from MCI to NC and dementia and (2) determine the effect of age, APOE, and indicators of cognitive reserve on the RR of reversion vs progression using multistate Markov modeling.

Methods We estimated instantaneous transition rates between NC, MCI, and dementia after accounting …

Prostacyclin Promotes Degenerative Pathology In A Model Of Alzheimer’S Disease, Tasha R. Womack, Craig T. Vollert, Odochi Ohia-Nwoko, Monika Schmitt, Saghi Montazari, Tina L. Beckett, David Mayerich, Michael Paul Murphy, Jason L. Eriksen

Sanders-Brown Center on Aging Faculty Publications

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that is the most common form of dementia in aged populations. A substantial amount of data demonstrates that chronic neuroinflammation can accelerate neurodegenerative pathologies. In AD, chronic neuroinflammation results in the upregulation of cyclooxygenase and increased production of prostaglandin H2, a precursor for many vasoactive prostanoids. While it is well-established that many prostaglandins can modulate the progression of neurodegenerative disorders, the role of prostacyclin (PGI2) in the brain is poorly understood. We have conducted studies to assess the effect of elevated prostacyclin biosynthesis in a mouse model of AD. Upregulated prostacyclin expression …

Age-Associated Gut Dysbiosis, Marked By Loss Of Butyrogenic Potential, Correlates With Altered Plasma Tryptophan Metabolites In Older People Living With Hiv., Smita Ghare, Richa Singhal, Vaughn Bryant, Sabina Gautam, Chanakya Charan Tirumala, Praneet Kumar Srisailam, Andrea Reyes-Vega, Dushan Ghooray, Craig J. Mcclain, Kristi Hoffman, Joseph Petrosino, Kendall Bryant, Varand Govind, Ronald Cohen, Robert L. Cook, Shirish Barve

Faculty and Staff Scholarship

Background:

Imbalance in tryptophan (TRP) metabolism and its neuroactive metabolites, serotonin and kynurenine (KYN), is a known pathogenic mechanism underlying neurocognitive impairment. Gut microbiota plays an important role in TRP metabolism, and the production of these neuroactive molecules affects neurocognitive function. Although both HIV infection and normal aging independently induce gut dysbiosis and influence TRP metabolism, their interactive effects on compositional/functional changes in gut microbiota and consequent alterations in TRP metabolites remain largely undetermined.

Methods:

Older people living with HIV infection (PLWH, aged 50–70 years, n = 22) were enrolled in this cross-sectional pilot study. Metagenomic analysis of fecal microbiome …

Over-The-Counter Analgesic Use Patterns In Appalachian Older Adults, Focusing On Non-Steroidal Anti-Inflammatory Drugs, Courtney Wellman Md, Jordan Ratcliffe Bs, William Rollyson Md, Adam M. Franks Md, Mike Grome Pa-C, Robert Walker Md

Marshall Journal of Medicine

Introduction

Over-the-counter (OTC) medications are commonly used by elderly patients to self-manage pain symptoms. Medications such as non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen and topical analgesics are readily available and therefore may seem harmless to patients. In the growing population of those 65 years and older, providers need to inquire about OTC medication use due to the increased risk for adverse reactions in this population. Complications related to these medications can be worsened by chronic disease, variable metabolism, polypharmacy, etc. which become more common in the older adults.

Methods

A survey was created to determine the prevalence and habits of OTC …

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder with loss of cognitive, executive, and other mental functions, and is the most common form of age-related dementia. Amyloid-β peptide (Aβ) contributes to the etiology and progression of the disease. Aβ is derived from the amyloid-β precursor protein (APP). Multiple microRNA (miRNA) species are also implicated in AD. We report that human hsa-miR20b-5p (miR-20b), produced from the MIR20B gene on Chromosome X, may play complex roles in AD pathogenesis, including Aβ regulation. Specifically, miR-20b-5p miRNA levels were altered in association with disease progression in three regions of the human brain: temporal neocortex, …

Therapeutic Treatment With The Anti-Inflammatory Drug Candidate Mw151 May Partially Reduce Memory Impairment And Normalizes Hippocampal Metabolic Markers In A Mouse Model Of Comorbid Amyloid And Vascular Pathology, David J. Braun, David K. Powell, Christopher J. Mclouth, Saktimayee M. Roy, D. Martin Watterson, Linda J. Van Eldik

Neuroscience Faculty Publications

Alzheimer's disease (AD) is the leading cause of dementia in the elderly, but therapeutic options are lacking. Despite long being able to effectively treat the ill-effects of pathology present in various rodent models of AD, translation of these strategies to the clinic has so far been disappointing. One potential contributor to this situation is the fact that the vast majority of AD patients have other dementia-contributing comorbid pathologies, the most common of which are vascular in nature. This situation is modeled relatively infrequently in basic AD research, and almost never in preclinical studies. As part of our efforts to develop …

Recent Advances In Our Molecular And Mechanistic Understanding Of Misfolded Cellular Proteins In Alzheimer’S Disease (Ad) And Prion Disease (Prd), Walter J. Lukiw

School of Medicine Faculty Publications

Naturally occurring neuron-abundant proteins including amyloid Aβ42 peptide and the microtubule-associated protein tau (MAPT) can, over time and under pathological situations, assume atypical conformations, altering their normal biological structure and function, and causing them to aggregate into insoluble and neurotoxic intracellular inclusions. These misfolded proteins ultimately contribute to the pathogenesis of several progressive, age-related and ultimately lethal human neurodegenerative disorders. The molecular mechanism of this pathological phenomenon of neuronal protein misfolding lends support to the ‘prion hypothesis’, which predicts that the aberrant folding of endogenous natural protein structures into unusual pathogenic isoforms can induce the atypical folding of other similar …

Nonpharmacological Practices For Reducing Agitation In Persons With Dementia, Meghan L. Farkas

Commonwealth Scholars Program

1 in 11 people aged 45 years and older experience subjective cognitive decline, with nearly a third identifying a decline in the ability to participate in social activities, work, or volunteering. There are twelve modifiable risk factors that can either increase or decrease an individual's possibility of developing Dementia. This can include excessive alcohol consumption, head injury, air pollution, lower education level, hypertension, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and infrequent social contact. These modifiable risk factors may prevent or delay up to 40% of dementias. Furthermore, many risk factors cluster around inequalities, which occur particularly in Black, …
