Oral Health Considerations For Aging Patients Living With Hiv/Aids, Madeleine Daily Dds, Susan Liu Dds, Yuna Park Dds, Mph, Ms, Emily Byington Msw, Ivette Estrada Ma, Mphil, Sunil Wadhwa Dds, Carol Kunzel Phd

The New York State Dental Journal

People living with HIV/AIDS (PLWH) have an increased life expectancy due to advances in antiretroviral therapy. In 1996, the life expectancy for a 20-year old living with HIV was 39-years old; today, it is >70-years old. As life expectancy increases, PLWH are burdened with age-associated comorbidities. This paper reviews the interaction between aging and HIV and how it affects social, physical, and oral health issues. The shift in demographics presents new challenges for clinicians in how to identify, address, and manage these complex manifestations. This review summarizes how to approach HIV-related changes when providing care as a dental clinician.

High Pulse Pressure Impairs Cerebral Artery Endothelial Function In Young, But Not Old, Mice, Nick R Winder, Emily H Reeve, Elise K Kronquist, Aleena Khurana, Byron Lee, Thuan Nguyen, Grant D Henson, Ashley E Walker

Faculty, Staff and Student Publications

One of the hallmarks of vascular aging is increased pulse pressure. This elevated pulse pressure is associated with deleterious effects on cerebral vascular function; however, it is unknown if age modulates the susceptibility to high pulse pressure. To examine the effects of age on the cerebral artery response to pulse pressure, we studied isolated cerebral arteries collected from young (6.1 ± 0.2 mo) and old (26.7 ± 0.5 mo) male C57BL/6 mice. Isolated cerebral arteries were exposed ex vivo to static pressure, low pulse pressure (25 mmHg), and high pulse pressure (50 mmHg). In cerebral arteries from young mice, endothelium-dependent …

Adventure And Spiritual Restoration: Older Adult Motivations For Undertaking A Pilgrimage On El Camino De Santiago, Holly Nelson-Becker, Joseph G. Pickard, Florian Sichling

Social Work: School of Social Work Faculty Publications and Other Works

A pilgrimage is an intentional journey undertaken for reasons that can increase a sense of well-being. Although originally completed for religious purposes, motives in contemporary times may include anticipated religious, spiritual, and humanistic benefits as well as appreciation of culture and geography. This quantitative and qualitative survey research explored the motivations of a sample subset age 65 and over from a larger study who completed one of the Camino de Santiago de Compostela routes in Spain. Consistent with life course and developmental theory, some respondents walked at life decision points. The analyzed sample was 111 people, nearly 60% of whom …

Supplementing Glycine And N-Acetylcysteine (Glynac) In Older Adults Improves Glutathione Deficiency, Oxidative Stress, Mitochondrial Dysfunction, Inflammation, Physical Function, And Aging Hallmarks: A Randomized Clinical Trial, Premranjan Kumar, Chun Liu, James Suliburk, Jean W Hsu, Raja Muthupillai, Farook Jahoor, Charles G Minard, George E Taffet, Rajagopal V Sekhar

Faculty, Staff and Students Publications

BACKGROUND: Elevated oxidative stress (OxS), mitochondrial dysfunction, and hallmarks of aging are identified as key contributors to aging, but improving/reversing these defects in older adults (OA) is challenging. In prior studies, we identified that deficiency of the intracellular antioxidant glutathione (GSH) could play a role and reported that supplementing GlyNAC (combination of glycine and N-acetylcysteine [NAC]) in aged mice improved GSH deficiency, OxS, mitochondrial fatty-acid oxidation (MFO), and insulin resistance (IR). To test whether GlyNAC supplementation in OA could improve GSH deficiency, OxS, mitochondrial dysfunction, IR, physical function, and aging hallmarks, we conducted a placebo-controlled randomized clinical trial.

METHODS: Twenty-four …

Don’T Forget The Importance Of Leisure Occupations For The Community Dwelling Elder, Susan Witt

Occupational Therapy Doctorate Capstone Projects

Leisure exploration is important to the community dwelling elder (CDE) as research indicates that social and leisure activities correlate with well-being in this population (Adams et al., 2011). This research project aimed to gain insight on the CDE’s perspective on leisure as they age in place and the role occupational therapists play in leisure promotion for this population. This mixed method study included quantitative data from the Activity Card Sort (ACS) assessment which provided data on how leisure and activities of daily living have changed with aging. Qualitative data was gained through semi-structured interview and explored the perspectives of the …

Short-Term Removal Of Exercise Impairs Glycemic Control In Older Adults: A Randomized Trial, Leryn J. Reynolds, Troy M. Williams, Joel E. Harden, Hannah M. Twiddy, Monica L. Kearney

Human Movement Studies & Special Education Faculty Publications

Postprandial glycemia (PPG) predicts cardiovascular disease, and short-term physical inactivity increases PPG in young, active adults. Whether this occurs in older, active adults who may be more prone to bouts of inactivity is unknown. This study determined if postprandial interstitial glucose (PPIG) was impaired in active older adults following the removal of exercise for 3 days (NOEX) compared to active young adults. In this randomized, crossover study, 11 older (69.1 ± 1.9 years) and 9 young (32.8 ± 1.8 years) habitually active (≥90 min/week of exercise) adults completed 3-days of NOEX and 3-days of normal habitual exercise (EX), separated by …

Unplanned Costs And Benefits: Gender And Spousal Spillover Effects Of Retirement On Health, Lauren Newmyer, Kendal L. Lowrey, Yuliana Levchenko

Sociology Faculty Publications

Objective: Our study assesses how women and men's health indicators are shaped by their spouse's retirement. Background: The retirement process can reshape the health of a retiree, but these effects can also extend onto the health of spouses. Although past research has largely focused on how men's retirement might negatively shape their wife's health outcomes, it is possible that wives' retirement has detrimental effects on their husband's health as well.

Method: Using data from the Health and Retirement Study (HRS), we employ a fuzzy regression discontinuity design to identify the causal effects of spousal retirement on indicators of physical and …

Extending Lifespan With Metformin: A Comprehensive Review And Proposed Study, Caroline Delvecchio

Scripps Senior Theses

Aging is a non-adaptive epiphenomenon that characterizes the terminal phase of life. Aging leads to the dysregulation of metabolic processes that subsequently drive the downregulation of critical nutrient sensing pathways and autophagy, while increasing inflammation, cellular senescence, stem cell depletion, reactive oxygen species, and DNA damage; the gestalt of which is the aging phenotype. Age-induced subcellular alterations impact the whole organism, from cosmetic factors, such as grey hair and wrinkles, to the development of cardiovascular diseases, cancer, and neurodegenerative diseases. Fortunately, humans may have discovered a means of delaying aging through treatment with metformin. Metformin is an FDA-approved drug that …

Protein Translation Paradox: Implications In Translational Regulation Of Aging, Harper S Kim, Andrew M Pickering

Faculty, Staff and Student Publications

Protein translation is an essential cellular process playing key roles in growth and development. Protein translation declines over the course of age in multiple animal species, including nematodes, fruit flies, mice, rats, and even humans. In all these species, protein translation transiently peaks in early adulthood with a subsequent drop over the course of age. Conversely, lifelong reductions in protein translation have been found to extend lifespan and healthspan in multiple animal models. These findings raise the protein synthesis paradox: age-related declines in protein synthesis should be detrimental, but life-long reductions in protein translation paradoxically slow down aging and prolong …

The Association Of Cognitive And Physical Functioning With Health And Mortality Outcomes Among Puerto Ricans, Cheyanne Celine Barba

All ETDs from UAB

Puerto Rico has experienced a rapid increase in the older adult population over the last decade. With a growing older adult population, the importance of healthy aging becomes increasingly more important to understand. Understanding the impact that impairments in cognitive and physical functioning have on older adults in Puerto Rico will be important to supporting the rapidly aging population. The current project proposed to (1) examine predictors of transition to frailty, (2) examine whether cognitive function and frailty are associated with healthcare utilization, and (3) examine frailty and cognitive impairment as predictors of mortality and Alzheimer’s disease related cause of …

Aging With Hiv And Comorbid Chronic Obstructive Pulmonary Disease, Jun Yeong Byun

All ETDs from UAB

Older adults with human immunodeficiency virus (HIV) experience a high prevalence of chronic obstructive pulmonary disease (COPD). Considering having either HIV or COPD is related to worse health outcomes in older adults, aging with both HIV and COPD may synergistically and negatively affect the health outcomes of older people with HIV (PWH) and comorbid COPD. The purpose of this dissertation was to explore the aging of PWH with COPD. This purpose was accomplished through three articles: 1) an adaptation of a gerontological model investigating what is known about the aging of PWH and people with COPD and extrapolating that to …

Utility Of Dna Methylation As A Biomarker In Ageing And Alzheimer’S Disease, Lidija Milicic, Tenielle Porter, Michael Vacher, Simon M. Laws

Research outputs 2022 to 2026

Epigenetic mechanisms such as DNA methylation have been implicated in a number of diseases including cancer, heart disease, autoimmune disorders, and neurodegenerative diseases. While it is recognized that DNA methylation is tissue-specific, a limitation for many studies is the ability to sample the tissue of interest, which is why there is a need for a proxy tissue such as blood, that is reflective of the methylation state of the target tissue. In the last decade, DNA methylation has been utilized in the design of epigenetic clocks, which aim to predict an individual’s biological age based on an algorithmically defined set …

Relationships Among Age, Relative Telomere Length, And Dna Methylation In Pteropus Bats, Erika E. Forest

Masters Theses

Bats are the longest-lived mammalian order relative to body mass, but questions remain about relationships among mechanisms related to aging. Relative telomere length (rTL) decreases with age in most mammals, but the relationship between age and rTL is highly variable among the few bat taxa studied to date. More recently, DNA methylation (DNAm), a type of epigenetic regulation in which methyl groups are added to cytosine-phosphate-guanine (CpG) sites across the genome, has been shown to be highly predictive of age in many species of bats. We examine the relationships among age, rTL, and DNAm in Pteropus pumilus and P. hypomelanus …

Association Of Leukocyte Telomere Length With Perceived Physical Fatigability, Rain Katz, Emma L Gay, Allison L Kuipers, Joseph H Lee, Lawrence S Honig, Kaare Christensen, Mary F Feitosa, Mary K Wojczynski, Nancy W Glynn, Llfs Research Group

2020-Current year OA Pubs

BACKGROUND: Leukocyte telomere length (LTL) is a potential genomic marker of biological aging, but its relation to fatigability, a prognostic indicator of phenotypic aging (e.g., functional decline) is unknown. We hypothesized shorter LTL would predict greater perceived physical fatigability, but that this association would be attenuated by adjusting for chronological age.

METHODS: Two generations of participants (N = 1997; 309 probands, 1688 offspring) were from the Long Life Family Study (age = 73.7 ± 10.4, range 60-108, 54.4 % women), a longitudinal cohort study of aging. LTL was assayed at baseline. Perceived physical fatigability was measured 8.0 ± 1.1 years …

Department of Neuroscience Faculty Papers

Introduction: Olfactory impairment in older individuals is associated with an increased risk of Alzheimer's disease (AD). Characterization of age versus neuropathology-associated changes in the brain olfactory pathway may elucidate processes underlying early AD pathogenesis. Here, we report age versus AD neuropathology-associated differential transcription in four brain regions in the olfactory pathway of 10 female African green monkeys (vervet, Chlorocebus aethiops sabaeus), a well-described model of early AD-like neuropathology.

Methods: Transcriptional profiles were determined by microarray in the olfactory bulb (OB), piriform cortex (PC), temporal lobe white matter (WM), and inferior temporal cortex (ITC). Amyloid beta (Aβ) plaque load in …

The Intersection Between Toxicology And Aging Research: A Toxic Aging Coin Perspective., John P. Wise Jr.

Faculty and Staff Scholarship

We are imminently faced with the challenges of an increasingly aging population and longer lifespans due to improved health care. Concomitantly, we are faced with ubiquitous environmental pollution linked with various health effects and age-related diseases which contribute to increased morbidity with age. Geriatric populations are rarely considered in the development of environmental regulations or in toxicology research. Today, life expectancy is often into one’s 80s or beyond, which means multiple decades living as a geriatric individual. Hence, adverse health effects and late-onset diseases might be due to environmental exposures as a geriatric, and we currently have no way of …

Aging On Parole: An Empirical Analysis Of Reentry, Reintegration, And Life Satisfaction, Angela Silletti Murolo

Dissertations, Theses, and Capstone Projects

As the prison population grays, so too does the people leaving prison. In New Jersey and New York, 35% and 26% of people on parole are over the age of 50 respectively. While older persons have lower recidivism rates compared to younger persons, there are physical, mental, and societal challenges that come with advancing age that can make reentry and reintegration a particularly difficult experience compared to younger persons. The aim of this dissertation is to explore the experiences of older adults on parole and the parole officers that assist them in their reentry and reintegration.

This study is unique …

Resilience: Key Factors Associated With Resilience Of Older People In Botswana, Magen Mhaka-Mutepfa, Sheila Shaibu

School of Nursing & Midwifery, East Africa

This study aims to determine key factors that predict resilience in older people. A cross-sectional design and quantitative methods were used for this study. Four districts were selected in Botswana using cluster random sampling. Data on resilience from 378 older adults aged 60 years+ [Mean Age (SD) = 71.1(9.0)] was collected using snowballing technique. Data on socio-demographics, protective and risk factors were also collected from urban and rural areas. CHAID (Chi-squared Automatic Interaction Detection) analysis was used to predict the strengths of the relationships among resilience and all predictor variables because the data were skewed. Five major predictor …

Epigenetic Grimage Acceleration And Cognitive Impairment In Bipolar Disorder, Camila N C Lima, Robert Suchting, Giselli Scaini, Valeria A Cuellar, Alexandra Del Favero-Campbell, Consuelo Walss-Bass, Jair C Soares, Joao Quevedo, Gabriel R Fries

Faculty, Staff and Student Publications

Bipolar disorder (BD) has been previously associated with clinical signs of premature aging, including accelerated epigenetic aging in blood and brain, and a steeper age-related decline in cognitive function. However, the clinical drivers and cognitive correlates of epigenetic aging in BD are still unknown. We aimed to investigate the relationship between multiple measures of epigenetic aging acceleration with clinical, functioning, and cognitive outcomes in patients with BD and controls. Blood genome-wide DNA methylation levels were measured in BD patients (n = 153) and matched healthy controls (n = 50) with the Infinium MethylationEPIC BeadChip (Illumina). Epigenetic age estimates were calculated …
