Cognitive screening using automated speech analysis: the effect of preferred language in bilingual Spanish-English speakers
| Funding Agency | NIH AIM AHEAD Hub Specific Projects – Year 4 |
| Investigator and Co-investigators | Catherine Diaz-Asper, Nathan Green, Sara Pappa, Mahederemariam Bayleyegn Dagne & Patricia Heyn |
| Title | Cognitive screening using automated speech analysis: the effect of preferred language in bilingual Spanish-English speakers |
| Duration | September 2025 – September 2026 |
|
Description |
Machine learning speech analysis models can detect Alzheimer ’s-related cognitive impairments by analyzing features like lexical diversity, syntactic complexity, pauses, and prosody. However, most are trained on monolingual native English speakers, limiting effectiveness in diverse populations, especially bilinguals. This project aims to develop new screening methods for mild cognitive impairment in older bilingual Spanish-English speakers, using accessible technology and AI to identify cognitive decline. The aim is to evaluate the ML model’s accuracy in both languages and assess whether features and performance differ by preferred language. |

|
Description |
The MCOA is developing a Self-Health Promotion Program in English & Spanish to enhance healthy aging for medically underserved populations in the medically underserved areas through culturally appropriate, community-based health screenings (oral/cognitive/physical) with lifestyle recommendations (diet/sleep/physical activity). The Healthy Elders Lifespan Potomac Program (HELPP) will expand interventions for chronic diseases by utilizing self-health improvement design to increase access to bilingual health support & promote long-term lifestyle enhancement gains. |

| Duration | September 2024 – September 2025 |
|
Description |
Marymount University will conduct an exploratory analysis using its AI/ML Health Equity Lab to develop an AI model to monitor health and falls risk using at home technologies (i.e., TVs, fitness devices) to support older adults in their Northern Virginia community. |
Complementary Integrative Rehabilitation Medicine: Cultivating Diversity in Research and Clinical Practice
| Funding Agency | National Center for Complementary Integrative Health |
| Investigator and Co-investigators | Patricia Heyn |
| Title | Complementary Integrative Rehabilitation Medicine: Cultivating Diversity in Research and Clinical Practice |
| Duration | May 2024 – May 2025 |
|
Description |
The Diversity Mentoring and Career Development in Complementary and Integrative Rehabilitation Medicine Workshop (DMCD CIRM),” aims to conduct a pre-conference workshop at the 2024 American Congress of Rehabilitation Medicine (ACRM) Annual Scientific Meeting in Dallas, Texas. The ACRM R13 Diversity CIRM Workshop held in conjunction with the 2024 ACRM Annual Scientific Meeting will provide research training, mentoring, and networking for emerging scholars interested in the field. The conference brings together members and experts from various disciplines worldwide, providing fellows a chance to connect. |
Defining Racial Health Equity (RHE): A Landscape and Systematic Review Protocol of Definitions, Terminology, and Related Concepts
| Funding Agency | Robert Wood Johnson Foundation (GRANT NUMBER: 79982) |
| Investigator and Co-investigators | Patricia C. Heyn, Elizabeth A. Terhune, Mahederemariam Dagne, Christi Piper, Vivian A. Welch, Damian Francis, Ana B. Pizarro, Anita Rizvi, Nila Sathe, Omar Dewidar, Colleen Ovelman, Tiffany Duque, Tamara Baker, Robert W. Turner II, Dru Riddle, Meera Viswanathan |
| Title | Defining Racial Health Equity (RHE): A Landscape and Systematic Review Protocol of Definitions, Terminology, and Related Concepts |
| Duration | September 2022 – August 2023 |
|
Description
|
Inequities in health exist within the United States, particularly across racial groups. Health equity has become a priority of the U.S. government and major health organizations; however, a consensus is lacking on racial health equity (RHE) definitions. RHE definitions and terminology will be reviewed from 1) websites from key health organizations, 2) theoretical and narrative studies, and 3) systematic reviews of RHE interventions. Comprehensive search strategies for theoretical and narrative articles (any year) and systematic reviews (since 2020) were developed with a research librarian using MeSH keywords. Databases including MEDLINE, PsychInfo, CINAHL, and the Campbell Collaboration library will be searched. Two reviewers will screen titles/abstracts and full texts. Disputes will be resolved by consensus. Preliminary results show that RHE definitions differ across health websites, although some definitions are shared and cite the same source. Many organizations, including those with a health equity agenda, do not report explicit definitions of RHE. Searches yielded ~2500 citations for theoretical and narrative articles and >7500 for systematic reviews. Our goal is to improve understanding of RHE constructs to help unify national RHE research efforts. This study was reviewed by multiple diverse stakeholders and is part of a larger research project, funded by the Robert Wood Johnson Foundation, on centering racial health equity in systematic reviews.

Remote online administration of Otago Exercise Program for Individuals with Dementia and Their Care Partners: A Feasibility Study
| Funding Agency | Alzheimer’s and Related Diseases Awards Fund (ARDRAF), Virginia Commonwealth University, Center on Aging |
| Investigator and Co-investigators | Julie Ries, Rita Wong, Patricia Heyn, Uma Kelekar, Catherine Diaz-Asper |
| Title | Remote online administration of Otago Exercise Program for Individuals with Dementia and Their Care Partners: A Feasibility Study |
| Duration | July 2022 – June 2023 |
|
Description |
Individuals with dementia (IwD) fall more and experience greater subsequent dependency and healthcare costs than their cognitively intact peers. The Otago Exercise Program (OEP) is a structured, exercise-based, fall-prevention program that could be promising for IwD, and remote administration could overcome substantial barriers to program access for IwD. This 16-week feasibility study uses components of the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance) to assess whether remote web-based OEP is a viable option for fall-prevention programming with IwD supervised by their care partners. |
The Influence of Distance Emergency Department Utilization of Non-Traumatic Dental Conditions (NTDCs) in the State of Maryland, 2017-2021
| Funding Agency | CareQuest Institute of Oral Health |
| Investigator and Co-investigators | Dr. Uma Kelekar |
| Title | The Influence of Distance Emergency Department Utilization of Non-Traumatic Dental Conditions (NTDCs) in the State of Maryland, 2017-2021 |
| Duration | January 2022 – December 2023 |
| Description |
Dr. Uma Kelekar, Associate Professor of Healthcare Management and a Senior Research Fellow from Marymount’s Center for Optimal Aging received a grant of $30,493 from the CareQuest Institute of Oral Health to study disparities in access to oral health in the Emergency Departments for non-traumatic dental conditions (NTDCs) in the state of Maryland, United States. In this study, Dr. Kelekar will estimate the effect of distance from the patient’s location to the nearest hospital as well as the nearest dental providers in the community and answer how proximity to the ED and dental offices, community health centers (CHCs) and urgent care clinics affect the utilization of NTDCs in the ED setting. She will use the secondary dataset State Emergency Department Database (SEDD) 2017-2021 data and employ advanced statistical methodologies to conduct this zip-code level analysis. The results of this study will fill in a significant gap in our understanding of the role of distance in the ED use of NTDCs and inform state policymakers to develop interventions that will help reduce NTDCs utilization in ED settings. |
