Funded Projects

The number of women misusing opioids during pregnancy has more than quadrupled in recent years, with fentanyl use rising to an all-time high. The exposure puts the fetus at serious risk for opioid withdrawal, as well as developmental and behavioral effects during infancy and childhood. This project will study the effects of fentanyl use during pregnancy on maternal physiology and stress, function of the placenta, pregnancy outcomes, as well as infant withdrawal symptoms, development, and stress. This research aims to identify new strategies for diagnosing, treating, and preventing opioid harm to the fetus and mother.

Managing the risks and benefits of opioid medications can be difficult. Although prescription opioids alleviate pain for some patients, serious adverse effects include opioid use disorder. There is a critical, unmet need for new technologies that significantly minimize the opioid doses needed for effective relief from moderate to severe pain. This project will develop a novel combination treatment containing a small amount of morphine along with pramipexole, a drug approved by the U.S. Food and Drug Administration for Parkinson’s disease and restless legs syndrome that reduces the reward-seeking behavior associated with opioids. The research will conduct safety studies to enable testing in human research participants.

Computerized clinical decision support tools offer a promising strategy to standardize and scale evidence-based practices to keep pace with the dynamic nature of the opioid crisis and overcome barriers to substance use disorder treatment. To change practice, such tools must be useful, usable, able to be integrated into routine care delivery, and supported by a multicomponent implementation strategy. This project will refine and evaluate the uptake, usability, and equity of a nationally disseminated multicomponent clinical decision support intervention to increase initiation of medication treatment for opioid use disorder in the emergency department.

There is little evidence available to guide clinical care for patients on long-term opioid therapy for whom risks exceed benefits. Given valid fears about both pain and withdrawal during decreased dosing (tapering), these individuals face challenges, including concerns about being abandoned by providers and uncertainty about the need to discontinue opioids. As such, these patients are hesitant to enroll voluntarily in opioid discontinuation research, further deepening the clinical evidence gap. This project will evaluate three effective and scalable interventions for individuals on long-term opioid therapy: (1) low-dose transdermal buprenorphine (without) of opioid withdrawal, (2) a brief cognitive behavioral intervention for pain, and (3) noninvasive brain stimulation.

Difficulty breathing is a hallmark symptom of an opioid-related overdose and can result in permanent brain injury or death within minutes. This project will develop a community-deployable Automated External Respiration System device that can restore and sustain breathing in people experiencing opioid-induced respiratory depression. The device stimulates the phrenic nerve in the chest that controls breathing until other medical interventions are available or the patient recovers. The research will develop and validate the automated external respiration system for testing in human research participants and ultimately aims to develop a system usable in a community setting.

Many people with opioid use disorder (OUD) also have a serious mental illness and other chronic conditions, which can be difficult for individuals and primary care providers to manage. A chronic disease self-management program is an established health care model in which peers help to educate patients about their condition(s) and build problem-solving skills to manage their health. Such programs have been effective in other populations and settings, but they have not been adapted for primary care patients who have OUD and SMI. This project will adapt and test a chronic disease self-management program for this population to understand its feasibility, acceptability, impact, and how best to put such programs into place widely in primary care settings.

Cerebral palsy (CP), the leading cause of childhood disabilities in the United States, refers to a group of neurological disorders that appear in infancy or early childhood and permanently affect body movement and muscle coordination. The experience of pain is one of the most common, poorly understood, and inadequately treated conditions in CP, impairing health and quality of life for both patients and caregivers. To understand why pain and motor dysfunction occur together, a model that accurately replicates both is needed. This project will validate an established, rabbit model of CP motor dysfunction for use in studying and developing effective treatments for CP-associated pain.
