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.

OPIOIDS: PREVENTION OF IATROGENIC OPIOID DEPENDENCE AFTER SURGERY New Strategies to Prevent and Treat Opioid Addiction NIDA University of Michigan, Ann Arbor WALJEE, JENNIFER FILIP ANN ARBOR, MI 2018
NOFO Title: NIH Research Project Grant (Parent R01)
NOFO Number: PA-16-160
Summary:

Morbidity and mortality related to prescription opioids are accelerating in the United States. Identifying the factors that lead to new opioid dependence among opioid naïve patients is a critical opportunity to reduce prescription opioid dependence and unintended diversion. In the United States, the majority of individuals who become opioid dependent receive their first opioid prescription following surgical procedures, yet there are no clinical guidelines to inform appropriate postoperative opioid use. We will examine the patient factors that are associated with postoperative pain and opioid consumption among a cohort of patients undergoing common elective abdominal procedures. We will identify the provider characteristics in postoperative opioid prescribing practices, and design and implement a provider-directed intervention to optimize postoperative opioid prescribing. Findings will inform patients and providers regarding the risk of opioid dependence following surgery, and will establish a patient-centered data infrastructure that yields continuous feedback to providers regarding appropriate opioid prescribing practices.

CANNABINOID-BASED THERAPY AND APPROACHES TO QUANTIFY PAIN IN SICKLE CELL DISEASE Clinical Research in Pain Management NHLBI University of Minnesota GUPTA, KALPNA 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:

Sickle cell disease (SCD) is an inherited hematologic disorder accompanied by severe pain, inflammation, and vascular injury. We propose that nociceptor activation by ongoing hypoxia/reperfusion (H/R) injury leads to the release of neuropeptides by sensory nerves in the skin, stimulating vascular insult and mast cell activation in SCD. In turn, mast cell tryptase activates protease-activated receptor 2 on sensory nerve endings, resulting in exaggerated neuroinflammation, vascular injury, and central sensitization. Our general hypothesis is that neurogenic inflammation contributes to pain in SCD and that cannabinoids provide analgesia by disrupting neurogenic inflammation and nociceptor sensitization. We also hypothesize that EEG and functional MRI can be used to optimize analgesic treatments in SCD. We propose to use transgenic sickle mice, and individual cells involved in evoking pain, to perform this translational study. A proof of principle study in humans will examine the effect of cannabis on pain in sickle patients.
