Gait stability arises from interactions between physiological, cognitive, and psychological systems, yet these domains are often assessed in isolation. This study examined multisystem predictors of anteroposterior margin of stability during walking (MoSAP) in community-dwelling older adults. Of 340 participants, 143 were retained after data quality screening (105 females; age: 70.8 ± 7.8 years). Participants completed the Physiological Profile Assessment (PPA), cognitive testing using Montreal Cognitive Assessment (MoCA), fear-of-falling evaluations using Modified Falls Efficacy Scale (MFES) and a biomechanical gait assessment during preferred and fast speeds. Participants were stratified into four PPA-based fall-risk groups: low, mild, moderate, and high risk. MoSAP …

Senescent Fibroblasts In Aging And Pulmonary Fibrosis, Sara B. Palega, Aiwei Y. Borengasser, Yan Y. Sanders Jan 2026

Senescent Fibroblasts In Aging And Pulmonary Fibrosis, Sara B. Palega, Aiwei Y. Borengasser, Yan Y. Sanders

Department of Biomedical and Translational Sciences Faculty Publications

Aging is a major risk factor for many chronic lung diseases, including Idiopathic Pulmonary Fibrosis (IPF), a fatal and incurable disease characterized by progressive fibrotic remodeling. Age-associated structural alterations, impaired regenerative capacity, and dysregulated cellular signaling collectively create a pro-fibrotic microenvironment. A central driver of this pathological shift is the accumulation of senescent cells, which undergo irreversible growth arrest and develop a robust pro-inflammatory senescence-associated secretory phenotype (SASP). Emerging evidence identifies senescent lung fibroblasts as critical mediators of IPF pathogenesis. These cells promote excessive extracellular matrix deposition, myofibroblast differentiation, and tissue stiffening, while simultaneously impairing epithelial regeneration. Together, these effects …

Violence Between Residents In Nursing Homes Is An Enduring Problem. The Agencies, Nursing Homes, And Residents Are Playing Hot Potato With The Responsibility, Cindy Marchionda, Rafael Escalara Montoto Dec 2025

Violence Between Residents In Nursing Homes Is An Enduring Problem. The Agencies, Nursing Homes, And Residents Are Playing Hot Potato With The Responsibility, Cindy Marchionda, Rafael Escalara Montoto

Capstones

Resident-to-resident aggression in nursing homes is a persistent issue, far more common than the general public realizes. While many of these violent situations can be managed, some tragically escalate to fatal outcomes, leaving families mourning the loss of their loved ones at the hands of a facility that was meant to provide safety and care during their final years. Experts agree that this issue is largely driven by chronic understaffing and insufficient training for employees on how to manage patients with dementia and aggression issues.

Best Practice Recommendations For Anesthesia Providers In Preventing Postoperative Delirium In The Geriatric Population Undergoing Non-Cardiac Surgery, Ana Primeaux, Ashanti Reed

Doctoral Projects

Postoperative delirium (POD) is a significant and preventable complication in geriatric patients undergoing non-cardiac surgery. Such complication is associated with foreseeable consequences, such as prolonged hospitalization, long-term cognitive decline, increased morbidity and mortality, and increased costs. Despite the emerging awareness of evidence-based nonpharmacologic and pharmacologic interventional strategies, POD still represents a clinical challenge for anesthesia providers.

Currently, there is a lack of clinical guidelines to guide formalized education and evidence-based interventions on POD prevention across anesthesia practice settings. Consequently, there is a critical need to raise awareness that the lack of clinical guidelines and the high incidence of POD may …

Net Effects Of Correlated Determinants Of Health Among U.S. Older Adults, Haomiao Jia, E I. Lubetkin

Publications and Research

Background

The health effect produced by a contributing factor alone may be different from the effect when other interacting factors are present. The effects of a set of contributors, estimated by regression coefficients, may be invalid or inappropriate if some of the predictors are correlated or the model has interaction and nonlinear terms. The net effect (NE) of a given contributing factor is the effect produced by the factor alone, not by other factors due to their correlations with the factor of interest. This study estimated NE of selected determinants of health for U.S. older adults.

Geriatric Brittle Type 1 Diabetes Mellitus: Case Study And Management Strategies, Saba Irfan, Amanda Cantu Sep 2025

Geriatric Brittle Type 1 Diabetes Mellitus: Case Study And Management Strategies, Saba Irfan, Amanda Cantu

Research Colloquium

“Brittle diabetes” describes a form of diabetes marked by severe, unpredictable fluctuations in blood glucose, often leading to frequent episodes of hypoglycemia and hyperglycemia. Though not formally recognized by major diabetes organizations, the term is clinically useful, especially for vulnerable populations such as older adults with Type 1 Diabetes Mellitus (T1DM). Age-related factors—cognitive impairment, mobility limitations, dexterity issues, sensory decline, inconsistent eating habits, and frailty—make glycemic control particularly challenging and require a personalized, multidisciplinary management approach.

The Causal Pivot: A Structural Approach To Genetic Heterogeneity And Variant Discovery In Complex Diseases, Chad A Shaw, C J Williams, Taotao Tan, Daniel Illera, Nicholas Di, Joshua M Shulman, John W Belmont Sep 2025

The Causal Pivot: A Structural Approach To Genetic Heterogeneity And Variant Discovery In Complex Diseases, Chad A Shaw, C J Williams, Taotao Tan, Daniel Illera, Nicholas Di, Joshua M Shulman, John W Belmont

Center on Aging Staff Publications

We present the Causal Pivot (CP) as a structural causal model (SCM) for analyzing genetic heterogeneity in complex diseases. The CP leverages an established causal factor or factors to detect the contribution of additional suspected causes. Specifically, polygenic risk scores (PRSs) serve as known causes, while rare variants (RVs) or RV ensembles are evaluated as candidate causes. The CP incorporates outcome-induced association by conditioning on disease status. We derive a conditional maximum-likelihood procedure for binary and quantitative traits and develop the Causal Pivot likelihood ratio test (CP-LRT) to detect causal signals. Through simulations, we demonstrate the CP-LRT’s robust power and …

Developing Deep Learning Methods For Cognitive Impairment Detection Based On Non-Invasive Data, Muath Alsuhaibani

Electronic Theses and Dissertations

Cognitive impairment detection is on the rise to help reduce the burden of healthcare costs on institutions and individuals. Mild Cognitive Impairment (MCI) is an early stage of cognitive decline progressing to Alzheimer’s disease (AD) or AD-related Dementia (ADRD). Detecting the early stages of AD/ADRD is crucial for early interventions among older adults to mitigate cognitive decline over time. However, the current diagnostic methods are often costly and/or invasive, such as MRI and PET scans. Thus, the search for non-invasive and cost-effective screening tools for the early detection of cognitive impairment using speech, language, visual, and motor data is growing. …

Lessons In Longevity From Blood Stem Cells Under Protein Stress, André Catic Jul 2025

Lessons In Longevity From Blood Stem Cells Under Protein Stress, André Catic

Center on Aging Staff Publications

Blood stem cells are among the body's longest-living cells despite being highly vulnerable to proteotoxic damage, which accelerates their aging. To maintain protein homeostasis (proteostasis), hematopoietic stem cells (HSCs) employ mechanisms such as reduced translation rates, high chaperone activity, autophagy, and selective protein degradation. These strategies mitigate protein misfolding, maintain quiescence, and preserve regenerative potential. Disruptions in proteostasis can lead to the elimination of impaired HSCs through differentiation or apoptosis, ensuring the integrity of the stem cell pool. Due to the systemic impact of the blood on aging and its experimental and clinical accessibility, investigating HSC proteostasis provides insights into …
