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.

Although medication-based treatment for opioid use disorder (OUD) can effectively reduce overdose risk and improve health outcomes, most people discontinue treatment too soon. Peer support specialists, who are individuals with direct experience with a substance use disorder, can offer social support to help individuals with OUD overcome barriers to treatment and recovery. This project will develop, deliver, and evaluate an innovative peer support specialist intervention to help individuals begin and stay in a treatment program. The research will focus on rural populations and underserved communities, using a dynamic modeling framework to prioritize at-risk communities for treatment offered through mobile health clinics.

Spinal cord stimulation (SCS) has been shown to provide effective relief for most people with chronic pain and eliminated the need for opioid therapy in more than half of those treated. However, traditional SCS approaches have encountered problems when glial cells coat the stimulation electrodes that distance the device from targeted neurons. This project will develop a novel hybrid Closed Loop Omnidirectional Neuromodulation with Electromagnetic fields (CLONE) system that is combined with magnetic-based stimulation to overcome glial coating of SCS electrodes, better target neurons in dorsal spine tissue, which may lead to better treatment of chronic neuropathic neck and low back pain.

People with opioid use disorders (OUD) have high rates of co-occurring alcohol, stimulant and other drug disorders, as well as mental disorders. Traditionally, treatment for OUD has been ?siloed? even though these high rates of co-occurring conditions emphasize the need for comprehensive treatment to address holistic needs. As the opioid crisis continues, attention to the whole person and access to comprehensive mental health and substance use treatment as well as primary care is needed. This study aims to better understand co-occurring mental health disorders, alcohol use disorders, and/or other substance use disorders among people with OUD, in the context of innovative integrated care networks for people with OUD. This study examines how innovative OUD treatment models work for individuals with co-occurring mental health and substance use by 1) assessing mental health treatment quality measures and outcomes; 2) testing how these innovative treatment models compare to other OUD treatment for people who have OUD and other substance use disorders; and 3) considering the ways people with OUD access co-occurring disorder care. The findings from this study will provide needed information to improve mental health, alcohol, and other substance use treatment for individuals with OUD, whether or not they are in OUD treatment and may provide information to help move the system from siloed efforts to truly integrated care

Although medications for opioid use disorder are effective and available, providers currently lack methods to monitor patients and thus inform improved dosing. This project will develop Strength Band Platform, an innovative artificial intelligence-based digital platform. The wearable device will collect patient physiological characteristics to detect relapse and withdrawal during treatment with medications for opioid use disorder in real-world settings. 

The opioid epidemic continues unabated in the United States, and despite the rapid expansion of this crisis, the nature of the risk factors that contribute to opioid misuse remain poorly understood compared with other substances of abuse. The goal of this project is to examine cannabis use and cannabis identification measures as risk factors for opioid misuse while also developing and evaluating novel implicit measures of opioid associations as risk factors for opioid misuse among an at-risk sample of adolescents. Findings from the proposed research are intended to improve the prediction of opioid misuse among adolescents and to potentially identify novel targets for prevention and intervention strategies that aim to combat the opioid epidemic.

Shoulder pain occurs in many patients who are recovering from a stroke. In addition to impairments in the ability to move, persistent shoulder pain contributes to depression, and often reduces quality of life. Although the cause of post-stroke shoulder pain is complex and not completely understood, it is thought to arise in part to damage of muscles and surrounding connective tissues (myofascial tissues) in the shoulder. This project will use advanced medical imaging techniques to create biomarkers of that can reliably identify myofascial tissues. The research will then test the ability of these biomarkers to monitor, and ultimately predict treatment responses in patients with post-stroke shoulder pain in the context of a randomized controlled clinical trial.

The study team developed an mHealth pain self-management intervention for the perioperative period (SurgeryPal) to target psychosocial risk factors and teach pain self-management skills. The goal of this proposal is to establish the effectiveness of the SurgeryPal psychosocial intervention to improve clinically meaningful outcomes in adolescents undergoing major musculoskeletal surgery, and to identify the optimal timing of intervention delivery. The study team will plan for the efficient implementation of a multisite randomized clinical trial at 25 centers in 500 youth ages 12–18 years undergoing spinal fusion surgery and their parents. Participants will be randomized to receive SurgeryPal or attention control condition during the preoperative and postoperative phases. Self-reported pain severity and interference and secondary outcomes will be assessed at baseline, 3-, and 6-months. If effective, this scalable, low cost intervention will allow broad implementation to prevent chronic postsurgical pain in youth.

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.

Fatal opioid overdose rates are higher among American Indian/Alaska Native populations than among Hispanics, African Americans, and Asian Americans, and are just below non-Hispanic Whites. AI/AN opioid overdose rates vary significantly by state and county; however, tribe-level differences are difficult to ascertain due to decentralized data systems that divide state health data and Indian Health Service data. This study will conduct a two-phase research project that leverages Center for Disease Control funding awarded to the Albuquerque Area Southwest Tribal Epidemiology Center for improving data quality in opioid overdose surveillance in New Mexico. In the first phase, geocoding and data linkages will be studied to address the need in New Mexico for tribe-specific data and analyses on opioid use disorder and opioid overdose. After disseminating analyses to tribal communities and Indian Health Service, Tribal and Urban Indian health facilities, the second phase of the study will establish a collaboration with interested tribes and facilities in a community-based participatory intervention research project to develop and test a culturally centered implementation program for providing medication for opioid use disorders to American Indian people.

A major barrier to developing new pain treatments has been the absence of infrastructure to facilitate well-designed and carefully conducted clinical trials to test the efficacy of promising treatments. The UF Health Specialized Clinical Center Network will include UF Health as “hub” and statewide partners serving as spokes as part of the EPPIC Network. The University of Florida (UF) has the capability to reach more than 50% of the population of Florida, the third most populous state of the United States, and the capacity to successfully enroll patients with varying pain conditions into clinical trial protocols through its hub and spoke infrastructure as part of EPPIC-Net.

Migraine is the most common neurological disorder. Currently available treatments fail to effectively manage migraine in most patients. Development of new therapeutics has been slow due in large part to a poor understanding of the underlying pathology of migraine. Endogenous proteases, released in the meninges by resident mast cells, have been proposed as a potential driver of migraine pain via an action on protease activated receptor type 2 (PAR2). The central hypothesis is that PAR2 expression in nociceptors that project to the meninges plays a key role in the pathogenesis of migraine pain. The aims are to: 1) use the established PAR2 development pipeline to design new PAR2 antagonists with improved drug-like properties; 2) use pharmacological tools in a novel mouse migraine model to further understand the potential role of PAR2 in migraine; and 3) use mouse genetics to study the cell type–specific role of PAR2 in migraine pain.
