Funded Projects

Addressing the current opioid overdose crisis requires tracking risky opioid use in a timely manner so that public health agencies can plan accordingly and supply life-saving resources. American Indian Tribes often lack such tools, even though American Indians and Alaska Natives have the highest rates of opioid overdose fatalities. This project will adapt commercialized monitoring technologies for use in Tribal communities, in consultation with affected Tribes. Through a partnership with a Tribal Fire Department and a software company providing data analytics for public safety agencies, this research will build a near real-time opioid overdose dashboard for use within Tribal boundaries. The findings may also improve data collection and outbreak monitoring for other substances, including methamphetamine and cocaine.

Knee osteoarthritis is one of the leading causes of chronic pain and disability worldwide, affecting more than 30% of older adults. Rates of this condition have more than doubled in the past 70 years and continue to grow sharply, given increases in life expectancy and body mass index among the U.S. population. This project supports a scientist from a group underrepresented in biomedicine to expand ongoing clinical research comparing various non-medication-based treatments for knee osteoarthritis.

Relapse is common in people with opioid use disorder, and recovery attempts often fail within 6 months. This research project will test a novel virtual reality intervention to improve recovery outcomes for people recovering from opioid use disorder. By increasing future orientation and delay-of-reward behavior with a precision medicine personalized experience, the intervention is designed to enhance advantageous decision-making and increase positive future outcomes. The results of this study will provide critical data for creating a commercially viable software product for facilitating relapse prevention and improving opioid use disorder recovery outcomes.

Chronic pain severely reduces the quality of life and ability to work for millions of Americans. Because misuse of opioids for chronic pain treatment contributes to opioid addiction and opioid overdose, there is an urgent need to study novel non-opioid mechanisms, targets, and treatment strategies for chronic pain. Many ion channels control the flow of electrical signals in peripheral sensory neurons and are thus key targets for understanding and treating chronic pain. This project will conduct detailed studies to identify major ion channel-related molecular activities, targets, and treatment strategies for chronic pain. In particular, this research will explore the role of a specific ion channel (lysosomal mechanosensitive ion channel, orTmem63A) in neuropathic pain resulting from nerve injury.

Many millions of Americans experience chronic pain, including about 25 million who report pain that substantially interferes with daily activities and reduces quality of life. Many chronic pain syndromes are more prevalent in females, and the incidence of chronic pain increases dramatically during adolescence. This research will use neuroimaging and other biological, social, and psychological data from a large study of young adolescents with or without pain to identify risk and protective factors for chronic pain.

During the COVID-19 public health emergency, the Substance Use and Mental Health Services Administration relaxed regulations for take-home dosing of methadone, offering an opportunity to improve methadone treatment access and address racial and ethnic disparities. This project aims to address regulatory, legal liability, and financial concerns related to clinical practice changes in opioid treatment programs. The project will first review state administrative data and conduct qualitative interviews to inform the intervention approach. The project will then evaluate an opioid treatment program intervention involving take-home methadone and its effect on take-home dosing, retention in care, and health outcomes for Black/African American and Hispanic/Latino individuals who take methadone for opioid use disorder.

More than 700,000 total knee replacement surgeries are performed each year in the United States to relieve joint pain in patients with end-stage osteoarthritis or rheumatic arthritis. However, many patients still experience significant pain after this procedure, calling for additional long-lasting, drug-free pain management strategies. This project will develop and test a commercial prototype device for persistent knee pain after total knee replacement. The injection-based method freezes peripheral nerves to reduce pain sensation.

New and safe therapeutic targets for treating opioid use disorder are needed. One promising approach is to test drugs currently approved by the U.S. Food and Drug Administration that work independently of the body’s opioid system. The medication memantine targets N-methyl-D-aspartate (NMDA) receptors in the brain, which have been implicated in the development and maintenance of addiction. This project will study a miniature version of multiple memantine molecules bound together that attaches only to NMDA receptors that are not within nerve connections. The research will evaluate the safety, misuse potential, and effectiveness of this molecular assembly in preclinical models. 

This project will study the harmful effects of illicit and prescription opioid use during pregnancy and its consequences on the mother, fetus, and placenta. The research will integrate multiple different technologies to study molecular changes in biospecimens taken from research participants. Samples to be collected at birth and characterized include plasma and urine from the mother across the three trimesters of pregnancy, tissue samples of the placenta, and fetal cord blood. This research aims to shed new light on the underlying biology of opioid exposure on the placenta during pregnancy toward development of early interventions during opioid-exposed pregnancies. 

Every year, more than 330,000 Americans are hospitalized for hip fractures. Rapid surgical intervention and pain treatment is critical to recover mobility and reduce other health complications. Ultrasound-guided regional anesthesia techniques are an effective alternative to opioid medication, but require specialized training for use in the emergency department. This project will develop and validate an easy-to-use ultrasound-based regional anesthesia guidance system, to ultimately improve access to non-opioid-pain treatment for hip fracture pain.

Use of remote data collection in developmental research can make it easier for families to participate in such research and increase sociodemographic diversity of participants. The goal of this project is to validate remote methods for testing early cognitive development, particularly attention and memory skills, in 4-, 8-, and 12-month-old infants from traditionally underrepresented populations in neuroscience research. The project will integrate multiple types of data to improve remote measurement of infant cognition within the home and will help expand understanding of developmental trajectories and mechanisms across diverse environments and contexts.

RADOR-KY is a near real-time, state-wide surveillance system to monitor prevention and treatment services for opioid use disorder (OUD). This project will fill gaps in this system by capturing data from agencies receiving state funding to provide treatment and support services for people with OUD. Access to the additional data will help expand and improve surveillance dashboards being used to coordinate and target resources for preventing overdose deaths.
