Sanders-Brown Center on Aging Faculty Publications

Elucidating the impact of the gut microbiome on Alzheimer’s Disease (AD) is an area of intense interest. Short chain fatty acids (SCFAs) are major microbiota metabolites that have been implicated as a mediator of gut microbiome effects in the brain. Here, we tested the effects of SCFA-treated water vs. saline-treated water on APPswe/PSEN1dE9 mice maintained under standard laboratory conditions. Mice were treated with SCFAs from five months of age until ten months of age, when they were evaluated for microbiome profile, impaired spatial memory as evaluated with the radial arm water maze, astrocyte activation as measured by Gfap expression and …

Enlarged Perivascular Spaces Are Negatively Associated With Montreal Cognitive Assessment Scores In Older Adults, Timothy J. Libecap, Valentinos Zachariou, Christopher E. Bauer, Donna M. Wilcock, Gregory A. Jicha, Flavius D. Raslau, Brian T. Gold

Sanders-Brown Center on Aging Faculty Publications

Emerging evidence suggests that enlarged perivascular spaces (ePVS) may be a clinically significant neuroimaging marker of global cognitive function related to cerebral small vessel disease (cSVD). We tested this possibility by assessing the relationship between ePVS and both a standardized measure of global cognitive function, the Montreal Cognitive Assessment (MoCA), and an established marker of cSVD, white matter hyperintensity volume (WMH) volume. One hundred and eleven community-dwelling older adults (56–86) underwent neuroimaging and MoCA testing. Quantification of region-specific ePVS burden was performed using a previously validated visual rating method and WMH volumes were computed using the standard ADNI pipeline. Separate …

Approximately 30% of elderly adults are cognitively unimpaired at time of death despite the presence of Alzheimer's disease neuropathology at autopsy. Studying individuals who are resilient to the cognitive consequences of Alzheimer's disease neuropathology may uncover novel therapeutic targets to treat Alzheimer's disease. It is well established that there are sex differences in response to Alzheimer's disease pathology, and growing evidence suggests that genetic factors may contribute to these differences. Taken together, we sought to elucidate sex-specific genetic drivers of resilience.

We extended our recent large scale genomic analysis of resilience in which we harmonized cognitive data across four cohorts …

Utilization Of Remap Conversation Tool To Improve Advance Care Completion In The Home-Based Palliative Care Community Setting, Gwendolyn Starkey

Doctor of Nursing Practice Projects

Background: The World Health Organization and the American Society of Clinical Oncology guidelines endorses mandatory communication skills training in care goals for seriously ill patients (Back et al., 2019). In one survey of primary care providers (PCP), 68% reported no formal training to discuss advance care planning (Comer et al., 2020). Advance care planning is essential to manage chronic conditions in our growing aging population to provide the best patient care. This manuscript aimed to discuss best practices and techniques in advance care planning and optimize skills to provide patient-centered care conversations that honor patient wishes, reduce unwanted hospitalizations, and …

Isolation And Rna Sequencing Of Single Nuclei From Drosophila Tissues, Colleen N Mclaughlin, Yanyan Qi, Stephen R Quake, Liqun Luo, Hongjie Li

Center on Aging Staff Publications

Many insect cells are encapsulated within the exoskeleton and cannot be dissociated intact, making them inaccessible to single-cell transcriptomic profiling. We have used single-nucleus RNA sequencing to extract transcriptomic information from multiple Drosophila tissues. Here, we describe procedures for the (1) dissociation of single nuclei, (2) isolation of single nuclei using two popular cell sorters, and (3) preparation of libraries for Smart-seq2 and 10× Genomics. This protocol enables generation of high-quality transcriptomes from single nuclei and can be applied to other species.

For complete details on the use and execution of this protocol, please refer to McLaughlin et al. (2021) …

Examining The Effects Of Passenger Conversation On Older Adult Driving, Allison Green, Meg Tedder, Amanda J. Mohler, Amanda M. Carpenter

Student Journal of Occupational Therapy

Older adults have impaired driving performance compared to other age groups, and auditory stimuli has adverse effects on driving performance (Karthaus & Falkenstein, 2016). Therefore, the purpose of this study was to expand knowledge of driving and passenger conversation within the older adult population. Participants (n = 17) completed a drive of 7.8 miles on a driving simulator twice; once without conversation and again with conversation. Both drives used the same simulated driving tasks to examine driving performance with and without conversation. Participants exhibited poorer driving performance from the first drive without conversation to the second drive with conversation, …

Avian Assisted Intervention During Covid-19 Pandemic Restrictions, Sandia Wood, Mary Thelander Hill

Student Journal of Occupational Therapy

Occupational Deprivation has been a present risk [ER1] for people in inpatient hospital settings such as Skilled Nursing Facilities (SNF) during the Coronavirus Disease 2019 (COVID-19) pandemic restrictions. Clients have described their days as “boring” and “unfulfilling.” Clients experiencing extended in-patient hospitalization, who already might experience great interruptions to their treasured roles, routines, and occupations, were further restricted from recreational and social opportunities usually present in those settings. This work describes the translation of the animal assisted intervention evidence base to an occupational therapy student-developed program at a SNF to address this deficit. A vibrant avian therapy partner gave moments …

The final portfolio contains a total of four research articles. Study designs include two randomized control trials, one cohort design, and one systematic review. All studies related directly to the PICO question and were used to determine best evidence for the feasibility of group therapy of the older adult population who have hip replacements in a rehabilitation setting.

Early Integration Of Palliative Care With Curative Oncology Treatment For Patients With Advanced Cancer: Implications For Clinical Nursing Practice, Rhea Rughani

Honors Projects

Palliative care, though clinically established to improve health-related quality of life measures for patients with advanced illness, remains underutilized and largely limited to end of life care. This project aims to inform oncology nursing practice through the analysis of literature supporting the early integration of palliative care with standard curative oncology treatment for patients with clinically advanced cancer. Informed by relevant research, clinical practice guidelines, and improved specialty palliative care training, oncology nurses and nurse practitioners are ideally situated to advocate for and initiate early palliative care integration, to holistically improve the standard approach to complex cancer care.

Plasmalogen Deficiency: A Risk Factor For Dementias And Potential Treatment Target, Mitchel A. Kling, Mallika Mendu, Rima F. Kaddurah-Daouk, Sheldon Jordan, Dayan B. Goodenowe

Rowan-Virtua Research Day

Altered lipid metabolism is implicated in the risk of sporadic Alzheimer’s disease (AD) and related dementias (ADRD); however, the precise mechanisms accounting for findings from observational studies remains to be fully elucidated.

Plasmalogens are a subclass of integral membrane phospholipids with unique properties that appear to play important roles relevant to the pathophysiology of AD and ADRD, including vesicle fusion necessary for synaptic neurotransmitter release, modulation of membrane fluidity and microdomain dynamics, membrane antioxidant functions, and neuroprotection. Like the more familiar phosphatides, plasmalogens are synthesized on a 3-carbon glycerol backbone; however, they differ from phosphatides by the presence of a …

The Role Of Physiologic Vision Deficits In Elderly Self Dispensing Medication Errors, Harrison Patrizio

Rowan-Virtua Research Day

Elderly populations are more prone to self-dispensing medication errors. Although some of these errors can be attributed to a patient’s disease, many errors are preventable with behavioral modification. As we age, the lens of the eye becomes yellow. This tints all light that passes through it causing deficits in color distinguishability.(Andreasen, 1980) Additionally, the lens of the eye hardens over time. This results in presbyopia, an inability to focus close objects.(Wolffsohn, 2018) These changes can cause elderly patients to misread labels or dispensed incorrect medication due to color shade similarities.(Cardarelli, 2011) Although these visual changes are well documented, current research …

Literature Review: Palliative Care In The Emergency Department, Alice Chang, James Espinosa, Alan Lucerna, Neelesh Parikh

Rowan-Virtua Research Day

With current medical advances, our patient population continues to age. This poses new challenges for healthcare practitioners to provide for elderly patients with complex and multifactorial medical needs. Particularly, this is a growing challenge in the emergency department (ED), where patients often present towards the last months of their lives. A study conducted by UCSF indicates 75% of patients in their last 6 month of life visited the ED. 56% to 99% of older adults do not have advance directives available at ED presentation. Therefore, ED visits towards the end of life is an opportune teaching moment for physicians to …

Sanders-Brown Center on Aging Faculty Publications

Cranial radiation is important for treating both primary brain tumors and brain metastases. A potential delayed side effect of cranial radiation is neurocognitive function decline. Early detection of CNS injury might prevent further neuronal damage. Extracellular vesicles (EVs) have emerged as a potential diagnostic tool because of their unique membranous characteristics and cargos. We investigated whether EVs can be an early indicator of CNS injury by giving C57BJ/6 mice 10 Gy cranial IR. EVs were isolated from sera to quantify: 1) number of EVs using nanoparticle tracking analysis (NTA); 2) Glial fibrillary acidic protein (GFAP), an astrocyte marker; and 3) …

Research outputs 2022 to 2026

The concept of age acceleration, the difference between biological age and chronological age, is of growing interest, particularly with respect to age-related disorders, such as Alzheimer’s Disease (AD). Whilst studies have reported associations with AD risk and related phenotypes, there remains a lack of consensus on these associations. Here we aimed to comprehensively investigate the relationship between five recognised measures of age acceleration, based on DNA methylation patterns (DNAm age), and cross-sectional and longitudinal cognition and AD-related neuroimaging phenotypes (volumetric MRI and Amyloid-β PET) in the Australian Imaging, Biomarkers and Lifestyle (AIBL) and the Alzheimer’s Disease Neuroimaging Initiative (ADNI).

Wellness Promotion Through Leisure Activity Among Community-Dwelling Older Adults, Gabriela Morrell-Zucker

Spring 2022 Virtual OTD Capstone Symposium

The purpose of this capstone project is to analyze the outcomes of an occupation-based wellness program which aims to address the problem of a lack of wellness promotion programs for community-dwelling older adults. Through structured programming older-adults demonstrated increased participation in leisure activities contributing to positive health and wellness. As the older adult population continues to grow, there is a need to engage community-dwelling older adult populations in wellness promotion through leisure activities. For this purpose, a quantitative approach examines the outcomes of program development from older adults' perspectives through a the CHAMPS Older Adult Physical Activity Questionnaire.

Association Between Concussions And Suicidality In High School Students In The United States, Grant L. Iverson, Justin E. Karr

Sanders-Brown Center on Aging Faculty Publications

Importance: Prior research has shown a statistically significant association between sustaining a concussion and suicidality in adolescents, but this prior research controlled for relatively few variables predictive of suicidality.

Objective: To examine whether sustaining a concussion remained a significant predictor of suicidality after controlling for relevant covariates (e.g., sexual abuse/assault, bullying, substance use, depression), hypothesizing that the relationship between concussion and suicidality would become non-significant after controlling for these variables.

Design: This study involved secondary data analysis of the 2019 Youth Risk Behavior Surveillance (YRBS) System, a national cross-sectional study of adolescents. Analyses were stratified by gender. …

Patterns Of Amygdala Region Pathology In Late-Nc: Subtypes That Differ With Regard To Tdp-43 Histopathology, Genetic Risk Factors, And Comorbid Pathologies, Matthew D. Cykowski, Anithachristy S. Arumanayagam, Suzanne Z. Powell, Andreana L. Rivera, Erin L. Abner, Gustavo C. Roman, Joseph C. Masdeu, Peter T. Nelson

Sanders-Brown Center on Aging Faculty Publications

Transactive response (TAR) DNA-binding protein 43 kDa (TDP-43) pathology is a hallmark of limbic-predominant agerelated TDP-43 encephalopathy (LATE). The amygdala is afected early in the evolution of LATE neuropathologic change (LATE-NC), and heterogeneity of LATE-NC in amygdala has previously been observed. However, much remains to be learned about how LATE-NC originates and progresses in the brain. To address this, we assessed TDP-43 and other pathologies in the amygdala region of 184 autopsied subjects (median age=85 years), blinded to clinical diagnoses, other neuropathologic diagnoses, and risk genotype information. As previously described, LATE-NC was associated with older age at death, cognitive impairment, …
