Funded Projects

Infants exposed to opioids during pregnancy can develop neonatal opioid withdrawal syndrome (NOWS). To date, clinicians generally use subjective evaluation to determine if an infant has NOWS, how severe the condition is, and if the infant needs treatment with or without medications. This project will evaluate whether an objective physiologic measure—continuous measurement of oxygen levels in the infant’s blood—can be used to develop a scoring system for assessing NOWS severity. The project will also develop and test a device to continuously monitor blood oxygen levels in the infants.

Chronic pain affects millions of Americans and remains poorly understood and challenging to manage. Researchers do not fully understand brain processes involved in chronic pain, which can vary considerably from person to person. This project will analyze brain function using magnetic resonance imaging (MRI) in individuals with and without chronic pain. The research will also directly determine the degree of pain-related brain imaging changes by using a large database of brain imaging data.

This study leverages recent federal and state opioid use disorder treatment initiatives as a platform for testing a promising mind-body intervention, Mindful Awareness in Body-oriented Therapy (MABT) as an adjunct to MAT in two clinical settings funded through the Washington Opioid State Targeted Response (STR) program. MABT, a novel mindfulness-based intervention, uniquely addresses aspects of awareness, interoception, and regulation that may be associated with pain, mental health distress, and behavioral control that increase risk of relapse and poor treatment outcomes. Each setting employs a variation of the nationally recognized Massachusetts Nurse Care Manager model. Using a randomized, two-group, repeated measures design, we will compare those who receive MABT+MAT to MAT only. The overarching goal of this application is to test MABT to improve MAT health outcomes among patients receiving buprenorphine to treat OUD.

MAT is the most effective intervention for opioid use disorder (OUD), and methadone maintenance treatment (MMT) is the most commonly prescribed MAT; however, approximately half of people who begin MMT discontinue within a year, and half of people retained in MMT have an opioid relapse within six months. Chronic pain, affecting most people on MMT, could be contributing to relapse in this group. Novel behavioral interventions that address both chronic pain and opioid relapse among people on MAT are needed. Mindfulness Oriented Recovery Enhancement (MORE) was recently developed to treat both pain and opioid misuse. MORE is a group intervention that combines training in mindfulness, cognitive reappraisal, and positive emotion regulation skills to target the dysfunctional cognitive, affective, and behavioral pathways that lead to opioid use relapse. The objective of this proposal is to examine the impact of MORE on opioid relapse and chronic pain among individuals receiving MMT.

This study proposes to test the delivery of a comprehensive cognitive behavioral therapy, reSET, to determine whether it can improve treatment adherence and long-term outcome among patients with opioid use disorder initiating medication-assisted treatment within a community-based"Hub and Spoke” Model of buprenorphine maintenance in central Pennsylvania. reSET (Pear Therapeutics, Inc.) is a commercially available version of the web-based Therapeutic Education System (TES) delivered as a mobile app and recently approved by the FDA as the first digital therapeutic adjunct for the treatment of substance use disorders. Through a series of interactive therapy lessons, the program teaches patients cognitive-behavioral coping skills to resist drug use and to address factors such as craving, depression, and other mood problems and relationship issues that are associated with risk of relapse. The CM component provides concrete rewards contingent on performance of key target behaviors.

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and over 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Painful episodes that require hospitalization and, in many cases, opioid treatment, are a hallmark of sickle cell disease. The source of these painful episodes remains unclear, and it is also unknown why pain severity varies so much among affected individuals. This project will identify novel, non-opioid targets to reduce sickle cell-related pain and search for biomarkers to help clinicians predict which individuals are at risk for increased pain, thereby improving health outcomes for people with sickle cell disease.

Fifty million Americans experience chronic pain, including about 25 million who report pain that substantially interferes with daily activities and reduces quality of life. Mental health problems, including depression, anxiety, and post-traumatic stress disorder, increase risk for severe chronic pain. This project will use genetic data, information about observable characteristics (phenotypic data), and neuroimaging data from three large databases to identify psychosocial factors that predict chronic pain, assess differences across diverse U.S. populations, and determine whether risk profiles predict post-surgical chronic pain.

Chronic pain is a significant public health problem associated with tremendous personal and economic burden. First-line treatment consists of opioid medications, but despite only moderate efficacy and unpleasant side effects, rates of opioid prescriptions have quadrupled over the past 15 years, and this has contributed to high rates of misuse, overdose, and mortality. Clearly, alternative, or non-opioid strategies for treating pain are needed. In this context, “opioid-sparing” medications refer to compounds that can be combined with and enhance the analgesic effects of lower-dose opioids without increasing the rewarding properties of either drug. There is preclinical evidence suggesting that cannabidiol (CBD) may have the potential to function as “opioid-sparing” medications, but its ability to alter opioid-mediated analgesia in humans has yet to be determined. This proposal will fill this gap by conducting a double-blind, placebo-controlled, within-subject randomized crossover study of the effects of CBD and morphine co-administration on pain sensitivity and subjective reinforcement on 28 healthy males and females. This is the first known study to investigate the ability of CBD to alter morphine’s analgesic effects in humans. If successful, the model will have a lasting impact on our ability to develop and test medications that reduce our reliance on chronic use of opioid medications for pain relief.

In 2018, new opiate prescribing limits (SB 273) were implemented across West Virginia to combat the opiate misuse epidemic. This study will utilize quantitative and qualitative measures to determine the effect of the recent opiate prescription laws in West Virginia, how a change in policy affects the opiate misuse epidemic, and how communities may apply this knowledge more broadly. The research team will: 1) collaborate with the West Virginia Board of Pharmacy to ascertain changes in opiate prescribing habits before and after the start of SB 273 using an interrupted time series methodology, and 2) achieve broad and deep understanding of how SB 273 has affected prescribing practices and experiences amongst primary care physicians, specialists (pan physicians, surgeons, emergency room physicians, etc.), and patients who currently or previously utilized opiate medications.

Prescription opioids provide pain relief, but overdose can be fatal because opioids also depress breathing through opioid-induced persistent apnea, when breathing stops. This research will determine whether targeted activation of a specific, opioid-insensitive brain region that triggers exhalation can increase tolerance to fentanyl-induced apnea. The research also seeks to identify the receptors responsible for this exhalation, which could be targets for new medications that prevent the negative impact of opioids on breathing. This research lays the groundwork for more preclinical and translational studies to prevent opioid-induced persistent apnea. 

A key component to addressing the current opioid overdose crisis is the ability to track dangerous opioid use in a timely manner so that public health agencies can plan accordingly. Direct reports about drug use and overdoses from social media might provide a useful early warning system that when combined with other sources, can provide policy makers and public health officials with powerful tools for monitoring this public health crisis. This project will explore the usefulness of Twitter and Reddit as a social media component of opioid use surveillance – in particular by monitoring mentions of fentanyl and synthetic opioids at various geographic levels (e.g., local or regional) and over time.

It is unclear if long-term use of opioids by head and neck cancer patients affects risk for depression, which is higher in this population compared to people without cancer. This knowledge could inform interventions such as increased opioid prescription safety or alternative pain management approaches and could thus help reduce the risk for depression-related outcomes. This project will use data from a national cancer database linked to Medicare claims and a Veterans Administration database to determine whether people with head and neck cancer that take opioid medications for more than 90 days have increased risk for new-onset or worsening depression or suicide death.

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and more than 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Sickle cell disease pain episodes are usually unanticipated, making it hard for people with the condition to manage their pain and putting them at risk for increased use of opioids and poor health outcomes. This project will use existing real-time health data to identify factors that can predict onset, severity, and worsening of daily pain in children with sickle cell disease.
