Pilot testing of a non-invasive, neuroimmune modulation tool—transcutaneous auricular vagus nerve stimulation (taVNS)—to enhance perioperative cognitive resilience in older adults
Sonali Advani, MBBS, MPH
Assistant Professor of Medicine - Infectious Diseases
Choosing urinary tests wisely to prevent infection-related stressors that impact resilience in older adults
My main research interests include prevention of catheter-related harm, implementation of diagnostic stewardship interventions, quality improvement, and improving metrics to better align with outcomes.

Evaluating Physical Resilience and Best Practices in Vision Rehabilitation of Stroke Patients: A Mixed Methods Approach
My independent line of research has evolved to not only study spatial attention disorders, but vision impairments due to age and neurological conditions. The strategy of my lab is to use multiple methods such as secondary data analyses and intervention development, in order to close research gaps and ultimately improve the visual and cognitive health of aging stroke survivors.

Accelerated metabolic aging in rheumatoid arthritis immune cells and skeletal muscle: A pilot study
Rheumatoid arthritis (RA) is a model disease for studying premature aging. Persons with RA suffer from early aging-associated metabolic comorbidities, and are at risk for low resilience, a decreased ability to resist functional decline. Mitochondrial function in RA and aging is a marker of cellular reserve, and is thus important for preserving resilience. RA and aged immune cells have abnormal mitochondrial function, which coincide with immune dysregulation. Skeletal muscle in both RA and aging is also marked by altered mitochondria. The pilot study will investigate whether dysfunction of mitochondria, the cellular metabolic “engine,” connects RA peripheral helper T-cells, macrophages and skeletal muscle abnormalities.
Objectives are twofold: to determine whether RA T cell, macrophage and skeletal muscle mitochondrial function abnormalities are associated; and to determine associations of exercise training on RA immune cell and skeletal muscle mitochondria.

Harness human cartilage repair capability to prevent and reverse osteoarthritis
Humans have a natural cartilage repair response which is high in the ankle, intermediate in the knee and low in hip cartilages. This repair response in humans is highly associated with the microRNAs used by salamanders and other limb regenerating animals to regenerate whole limbs. This project will evaluate the ability of microRNAs as a therapy to improve cartilage resilience to injury in vitro, and build the foundation for further evaluation in animals for microRNAs' ability to prevent and reverse the most prevalent of age-related diseases, osteoarthritis, for which we currently have no disease-modifying treatments.

Identification of biomarkers of cognitive resilience in the Duke Performance Across the LifeSpan (PALS) Study
Cognitive resilience is defined as preserved cognitive function in the setting of “stressors” that adversely affect cognitive function; it may explain – in part – the heterogeneity of cognitive function in older adults who otherwise appear clinically similar, especially with respect to risk factors for Alzheimer’s disease and related dementias (ADRD). Blood-based biomarkers of cognitive resilience would be useful to identify protective factors and test resilience-building interventions that preserve cognitive function in the setting of these stressors; currently, no such biomarkers exist. Building on previous work, I propose to develop a measure of cognitive resilience in a subset of community-dwelling older adults from the Duke Performance Across the LifeSpan (PALS; N=297) study with repeat cognitive testing over 3 years. Using this measure, I will identify biomarkers reflecting dysregulation in "Hallmarks of Aging" pathways that are predictive of cognitive resilience.
Nazema Siddiqui, MD (Dept. of Obstetrics and Gynecology)
Effects of aging and the urinary microbiome on recurrent urinary tract infections
Specific interests include: 1) pathophysiology of overactive bladder with particular emphasis on epigenetic mechanisms; and 2) studying the urinary microbiome with aging and in women with recurrent urinary tract infection. Additional interests include clinical outcomes research after surgery for prolapse and other pelvic floor disorders.

Physical Resilience to Pain with Activity Influences among Seniors (PRAISE) – Feasibility Study
Research focuses on development of tailored multi-factorial interventions that prevent disability among older adults with low back pain. Low back pain poses a major risk to senior health, as it is the global leader in years lived with disability and strongly associated with mobility disability. However, it is not clear why some older adults with low back pain succumb to mobility disability while others do not. This REC study will determine the feasibility of assessing three factors that may explain mobility disability among older adults with low back pain: pain with activity, fear of movement, and dynamic inflammatory response to movement.

High intensity interval training to improve pre- and peri-transplant function and outcomes
Research focuses on strategies to reduce complications of HCT and ranges from preclinical studies using murine models of HCT to Phase 1 and Phase 2 clinical trials. Areas of interest include the role of the microbiota (the trillions of bacteria living in and on our bodies), nutrition, and exercise in modulating HCT outcomes such as graft-versus-host disease (GVHD) and infections.
