Funded Projects

Current evidence indicates that chronic pain after a traumatic injury is influenced by the body’s response to stress. This project will conduct a comprehensive analysis of gene expression after traumatic stress exposure in a range of animal models in various body regions including the brain (amygdala, hippocampus, hypothalamus) and spinal cord, as well as nerves and immune cells throughout the body. These studies will be conducted in animals with no stress exposure as well as in animals treated with a molecule (FKBP51) known to block the stress response. This research will enhance understanding of how FKBP51 and post-injury stress affect pain processes.

We propose to estimate the impact of expanded access to medication-assisted treatment (MAT) in prisons and jails on post-release rates of overdose. Our approach will use agent-based modeling, data collected through the parent study, existing surveillance data, and recently published data from similar settings to understand how different MAT interventions in the prison and jail setting impact overdose death post-release. We will examine the impact of standard of care/no intervention, providing access to depot-naltrexone alone, providing access to all three MATs to only those who were prescribed it prior to incarceration, and comprehensive provision of all three MATs on post-release rates of overdose. These models will incorporate advanced methodological techniques that will allow for the investigation of engaged treatment, program attrition, and other complex events on a population level. This study’s findings may be used by health agencies, policymakers, and correctional systems to inform their efforts to expand MAT access.

African American adults are less likely to receive analgesics, particularly opioids. Research in the pediatric surgical population is limited, but the pattern of disparate use of opioids appears consistent with adults. Furthermore, adolescent access to prescribed opioids has increased, both through physician prescribing and misuse of medications prescribed to family members or friends. This study will explore the interrelated impacts of policy, clinical need, and sociodemographic factors by combining Medicaid claims and electronic health record data with findings from a statewide opioid policy inventory. We will focus on discharge prescribing of opioids in three high-volume pediatric surgical procedures: tonsillectomy/adenoidectomy, supracondylar fracture, and appendectomy. We aim to 1) determine the extent of racial disparities in postoperative discharge opioid prescribing since the 2011 onset of enhanced opioid prescription reduction activities and 2) develop an expanded model to assess the linkage between differential opioid use for pediatric postoperative pain and opioid use-related outcomes.

This research provides support to strengthen data management, data sharing, and data readiness efforts within the HEAL Initiative. This support further fosters collaboration among HEAL awardees and enables maximal data discoverability, interoperability, and reuse by aligning with the FAIR (Findable, Accessible, Interoperable, and Reusable) principles. It also provides an opportunity for existing HEAL Initiative award recipients to increase data “FAIR”-ness, participate in coordinated HEAL Initiative activities to build community around data sharing, and foster sustainability of HEAL Initiative digital assets.

Substance use disorders (SUDs) can have devastating consequences for people with serious mental illness (SMI). SUDs can increase morbidity and mortality and are associated with higher healthcare and social costs, homelessness, and incarceration. Unfortunately, despite the availability of effective treatments, most individuals with co-occurring SMI and SUD (COD) never receive SUD treatment. We propose to evaluate system, provider, and patient-level facilitators and barriers and develop an implementation strategy and toolkit to promote the use of medication-assisted treatment (MAT) for people with COD. Aims 1–3 seek to assess organizational capacity (at the system and provider level); organizational readiness (at the provider level); and perceived needs, attitudes, and preferences (at the patient level) to identify barriers and facilitators. In Aim 4, we will use findings from Aims 1–3 to guide development of the implementation strategy and toolkit, using stakeholder input and a systematic process for strategy development.

Opioids and other addictive substances have powerful rewarding properties that drive the development of addiction. They also have aversive properties that motivate their avoidance and protect against addiction. This project will explore the role of Type 2 Taste Receptor proteins (Tas2Rs or T2Rs) in regulating the aversive properties of opioids, potentially establishing an entirely new class of receptors that can be targeted for the development of novel addiction therapeutics.

Adolescents face increased HIV risk, infrequent testing, inconsistent linkage to care, and a lack of prevention-related knowledge. We propose to complete and evaluate the Mobile Augmented Screening (MAS) tool to privately and discretely offer routine HIV testing and counseling, including prevention education, to high-need, diverse adolescent and young adult populations at a low cost. The MAS will consist of a tablet-based intervention including a brief video designed to increase adolescent HIV testing, automated text messages to facilitate linkage to care for those who test positive, and text-based education for those who test negative or decline testing. Phase I was conducted with young emergency department (ED) patients. Preliminary evaluations indicate the video led to significant knowledge increases and encouraged testing. In phase II, we seek to complete intervention development and evaluate through a randomized controlled trial with ED patients, with qualitative interviews for a subset of young patients and ED staff.

Since 2002, persons with opioid use disorders who desire medication-assisted treatment can be treated with buprenorphine, which has been shown to be efficacious. Buprenorphine treatment can occur in any medical office-based setting, is prescribed by any physician who seeks to become waivered, and is taken by patients at home unsupervised. However, without visual confirmation of medication ingestion, providers remain unsure if patients divert part or all of their buprenorphine medication. This project will develop the technical and logistical workflow needed to implement a video-­based application, miDOT, for office-­based buprenorphine monitoring during the initial months of care, which will allow health care providers to monitor whether patients ingest the drug and adhere to treatment. The project will configure a video-based DOT platform, evaluate its effectiveness in securing medication ingestion and care retention for illicit opiate users, and solidify routes of sustainable commercial viability with commercial partners.

There are alarming rates of substance abuse and diversion in hospitals, with multiple studies finding that roughly 10% of our nation’s nurses, anesthesiologists, and pharmacists are currently diverting drugs in their workplaces. Diversion continues even though most hospitals already lock addictive drugs in Automated Dispensing Machines (ADMs) and run monthly “anomalous usage” computer reports to try to detect diversion. This SBIR project will research mechanisms to detect when health care workers (HCWs) in hospitals steal or “divert” legal drugs, either to abuse themselves or to illegally sell to others, by building a computer system with (a) automated data feeds from multiple existing hospital computer systems and (b) advanced analytics to flag potential diversion for investigation. This research has the potential to reduce injuries to HCWs who are becoming addicted, destroying their careers, jeopardizing their patients’ safety, and increasingly dying from drug diversion overdoses.

This project supports a post-doctoral trainee to develop the skills and knowledge needed to pursue a career in clinical pain research. The research will involve optimizing a GetActive mind-body activity program to overcome barriers that prevent disadvantaged older adult populations in community health clinics from access to non-pharmacological pain management strategies. The research will include qualitative analysis of secondary data, a literature review to evaluate methods, and feasibility for establishing a community advisory board for the GetActive project.

Stigma is a key barrier to retention in medication-based treatment for opioid use disorder, particularly among low-income, minority individuals. Stigma that exists at multiple levels contributes to poor retention in care, including internalized and anticipated stigma at the individual level, as well as enacted stigma at the health care provider- and community levels. There is an urgent need to develop and evaluate innovative strategies to reduce stigma at these multiple levels among low-income, racial/ethnic minority individuals to improve engagement in care. One of the most promising strategies to reduce multiple intersecting stigmas simultaneously and improve engagement in care for low-income, minority individuals is through the use of peer recovery coaches (PRCs). PRCs, individuals who have gone through the recovery process themselves and are typically state-certified, have been shown to be more acceptable for engaging and retaining low-income, racial/ethnic minority patients in treatment compared to other health workers. However, scarce research has formally evaluated the effects of PRCs on stigma. This study will test how a PRC model can reduce multiple intersecting stigmas among low-income, racial/ethnic minority individuals to improve retention in methadone treatment.

Among the more than half-million adults entering addiction treatment for prescription opioid abuse every year, 50%-60% report co-morbid chronic pain, and 80% report that pain triggers relapse. Individualized/self-stigma among adults with substance abuse has been shown to lead to delayed recovery, increased relapse and reduced treatment-related attendance. Stigma may induce significant burden on patients with OUD and chronic pain and there may be unique characteristics of stigma for this population due to the overlap between medical treatment and substance abuse. Multiple sources of stigma may be imposed including internalized/self-stigma as well as intragroup/peer-to-peer (?horizontal?) stigma whereby peers impose stigma upon each other based on the type and severity of past drug use. Furthermore, stigma could be ?vertical? in that stigma may be enacted by health care providers or by treatment center staff. However, there is notably a lack of research and related assessment tools to measure these multidimensional facets of stigma, particularly in patients with OUD and chronic pain. The investigators will utilize a mixed-methods approach to evaluate internalized/self-stigma, anticipated/expected stigma and enacted stigma using existing standardized surveys, and to describe horizontal and vertical stigma in individuals with OUD and pain at multiple sites. In addition, the investigators will integrate the quantitative and qualitative information to help inform modifications to the psychotherapy component (I-STOP) of the parent award intervention, which would then also target multidimensional stigma in patients with OUD and chronic pain.

Many molecular gates known as ion channels control the flow of electrical signals to sensory neurons and are thus key mechanisms and targets for understanding and interrupting pain signals. Recent breakthroughs in structural and computational biology shave illuminated specific molecular shapes of ion channels, which permits the improved design and refinement of small, stable protein-like molecules (peptide antigens). These peptides can stimulate an immune response that can then be targeted with a bioengineered antibody to match the peptide antigen. This project will test bioengineered antibodies in a rat model of chemotherapy-induced peripheral neuropathy within a region of the rat spinal cord that transmits signals to and from the brain.
