A Foundation to Examine Reasons for Discontinuation for Buprenorphine Care in the Veterans Health Administration Translation of Research to Practice for the Treatment of Opioid Addiction Enhancing the National Drug Abuse Treatment Clinical Trials Network to Address Opioids NIDA HENNEPIN HEALTHCARE RESEARCH INSTITUTE BART, GAVIN; JOSEPH, ANNE Minneapolis, MN 2018
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

This health care data mining study analyzes existing Veterans Health Administration data sets to examine patient and organizational characteristics associated with buprenorphine termination during outpatient OUD treatment. This project will generate data useful for predictive modeling on how to implement targeted approaches to improve retention in OUD treatment. An objective is to identify patient, provider and system targets to reduce unnecessary or inappropriate discontinuation of buprenorphine care. These analyses are critical for establishing initial constructs to evaluate reasons for treatment discontinuation based upon patient, provider and system factors in different health care settings.

ETHNIC DIFFERENCES IN ENDOGENOUS PAIN REGULATION: PET IMAGING OF OPIOID RECEPTORS Clinical Research in Pain Management NIMHD Johns Hopkins University CAMPBELL, CLAUDIA MICHELLE Baltimore, MD 2018
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

Ethnic groups show substantial variability in the experience of acute and clinical pain, with African Americans (AAs) having more clinical pain conditions and higher levels of pain severity and pain-related disability compared to non-Hispanic whites (NHW). Ethnic differences in opioid neurotransmitters suggest that these systems function less efficiently among AAs and may account for differences in pain and analgesic responses. The overwhelming majority of clinically used opioids elicit their effects through activation of the mu-opioid receptor, making it a relevant target for investigation. We propose to examine ethnic differences in the supraspinal endogenous opioid system using positron emission tomography (PET) imaging of mu-opioid receptors employing the mu-selective agonist [11C]carfentanil. Healthy AAs and sex-, age-, SES-matched NHW participants will undergo one baseline (non-pain) and one capsaicin-induced pain PET session using [11C]carfentanil. The current proposal will measure µ-opioid binding potential and examine its role in ethnic group differences in pain sensitivity.

SEVERE PAIN DURING WOUND CARE PROCEDURES: MODEL AND MECHANISMS Clinical Research in Pain Management NINR University of Iowa GARDNER, SUE E Iowa City, IA 2018
NOFO Title: Chronic Wounds: Advancing the Science from Prevention to Healing (R01)
NOFO Number: RFA-NR-15-001
Summary:

Wound care procedures (WCPs), such as dressing changes, cause moderate to severe pain in 74% of patients, nearly half of whom experience severe pain. Mainstay recommendations to prevent pain during WCPs have focused on either administration of preventive and procedural analgesia or use of expensive, non-adherent dressings. However, it is unclear which patients to target for analgesia or expensive dressings, leading to their inappropriate over- or underuse. To achieve the aims of the study, a comprehensive set of wound, patient, and biological factors will be measured concurrently with pain during a dressing change among a sample of 450 inpatients with open wounds. A predictive model will be developed and biological mechanisms will be examined using logistic regression. The proposed study has the potential to make significant contributions because clinicians will be able to target those patients requiring preventive pain control, thereby eliminating the spiraling impact of painful procedures on nociceptor sensitization.

PROSPECTIVE STUDY OF RACIAL AND ETHNIC DISPARITIES IN CHRONIC PAIN AND PAIN BURDEN Clinical Research in Pain Management NIMHD Rand Corporation MARSHALL, GRANT Santa Monica, CA 2018
NOFO Title: Mechanisms, Models, Measurement, & Management in Pain Research (R01)
NOFO Number: PA-13-118
Summary:

Data suggest that members of minority groups are more likely to develop chronic pain and to have greater pain burden. We will identify a set of promising intervention targets for reducing or eliminating racial/ethnic pain disparities. We will interview adult survivors of serious physical injury, comprised of roughly equal proportions of African-Americans (AA), Latinos, and non-Latino Whites (NLW), and examine their medical records for information on injury severity and medication use in-hospital. Our aims are to determine whether: 1) AA and Latino physical injury survivors experience more severe pain relative to NLW; 2) AA and Latino injury survivors experience greater pain burden relative to NLW counterparts; 3) differences in pain severity burden are linked to a set of target candidates for interventions; and (4) pain outcomes in at-risk minority groups can be linked to a set of target candidates for group-tailored interventions to reduce pain severity and pain burden.

EFFECTS OF OPIOID USE DISORDER IN PREGNANCY ON LONG-TERM MATERNAL AND CHILD OUTCOMES Enhanced Outcomes for Infants and Children Exposed to Opioids NICHD Indiana University - Purdue University Indianapolis SADHASIVAM, SENTHILKUMAR Indianapolis, IN 2018
NOFO Title: Opioid Use Disorder in Pregnancy (R01)
NOFO Number: RFA-HD-18-036
Summary:

Neonatal abstinence syndrome (NAS) rates have increased since 2000. To determine multifactorial genetic, psychosocial predictors of opioid-related maternal and infant outcomes using rigorous prospective longitudinal design, innovative combinatorial pharmacogenetic approach, fetal MRI, and neonatal brain resting state functional MRI analysis, we hypothesize that a combination of maternal and infant genetic profiles, maternal psychosocial factors, maternal opioid treatment response, fetal and neonatal neurodevelopment, and NAS treatment will affect maternal and childhood outcomes with prenatal opioid exposure. The specific aims are to (1) Identify high-risk genetic profiles and psychosocial factors in pregnant women with opioid use disorder (OUD) and predisposing to poor maternal opioid maintenance treatment outcomes; (2) Determine maternal-infant genetic profiles and maternal opioid treatment factors predicting adverse fetal development, severity of NAS, and neonatal brain function; and (3) Develop predictive models for maternal opioid relapse and poor long-term neurodevelopmental outcomes in children with in utero opioid exposure.
