Objective: There is high unmet need for effective behavioral treatments for chronic pain patients at risk for or with demonstrated histories of opioid misuse. Despite growing evidence supporting technology-based delivery of self-management interventions for chronic pain, very few such programs target co-occurring chronic pain and aberrant drug-related behavior. This randomized controlled trial evaluated the effectiveness of a novel, web-based self-management intervention, grounded in cognitive behavior therapy, for chronic pain patients with aberrant drug-related behavior...

Antagonists of the nociceptin receptor (NOP) are raising interest for their possible clinical use as antidepressant drugs. Recently, the structure of NOP in complex with some piperidine-based antagonists has been revealed by X-ray crystallography. In this study, a multi-flexible docking (MF-docking) procedure, i.e. docking to multiple receptor conformations extracted by preliminary molecular dynamics trajectories, together with hybrid quantum mechanics/molecular mechanics (QM/MM) simulations have been carried out to provide the binding mode of two novel NOP antagonists, one of them selective (BTRX-246040, formerly named LY-2940094) and one non selective (AT-076), i...

The melanin-concentrating hormone (MCH) is a peptidergic neuromodulator synthesized by neurons in the lateral hypothalamus and zona incerta. MCHergic neurons project throughout the central nervous system, indicating the involvements of many physiological functions, but the role in pain has yet to be determined. In this study, we found that pMCH-/- mice showed lower baseline pain thresholds to mechanical and thermal stimuli than did pMCH+/+ mice, and the time to reach the maximum hyperalgesic response was also significantly earlier in both inflammatory and neuropathic pain...

The voltage-gated sodium channel NaV1.7 plays a critical role in pain pathways. We generated an epitope-tagged NaV1.7 mouse that showed normal pain behaviours to identify channel-interacting proteins. Analysis of NaV1.7 complexes affinity-purified under native conditions by mass spectrometry revealed 267 proteins associated with Nav1.7 in vivo The sodium channel β3 (Scn3b), rather than the β1 subunit, complexes with Nav1.7, and we demonstrate an interaction between collapsing-response mediator protein (Crmp2) and Nav1...

The μ opioid receptor (MOR) in the nucleus accumbens (NAc) is involved in assigning pleasurable, or hedonic value to rewarding stimuli. Importantly, the hedonic value of a given rewarding stimulus likely depends on an individual's current motivational state. Here, we examined the involvement of MORs in the motivation to interact with a novel or a familiar (cage mate) conspecific in juvenile rats. First, we demonstrated that the selective MOR antagonist CTAP administered into the NAc reduces social novelty preference of juvenile males, by decreasing the interaction time with the novel conspecific and increasing the interaction time with the cage mate...

BACKGROUND: Behavioral studies demonstrated that the administration of Withania somnifera Dunal roots extract (WSE), prolongs morphine-elicited analgesia and reduces the development of tolerance to the morphine's analgesic effect; however, little is known about the underpinning molecular mechanism(s). In order to shed light on this issue in the present paper we explored whether WSE promotes alterations of μ (MOP) and nociceptin (NOP) opioid receptors gene expression in neuroblastoma SH-SY5Y cells...

OBJECTIVE: Historically, regional anesthesia for surgery on the posterior thoracic wall has been limited to neuraxial and paravertebral nerve blocks. The erector spinae plane (ESP) block is a novel technique that anesthetizes the dorsal rami of the spinal nerves innervating the posterior thoracic wall. We report the use of the ESP block for this clinical application in a pediatric patient. CASE REPORT: A healthy 3-year-old girl was scheduled for resection of a giant paraspinal lipoma extending over the T4-T7 dermatomes...

Mouse VD-hemopressin(α) (VD-Hpα) is an undecapeptide that selectively activates CB1 cannabinoid receptor in in vitro functional tests, and exerts CB1-mediated central antinociception in the mouse tail-flick assay. The aim of the present study was to further investigate the analgesic properties of supraspinal mouse VD-Hpα in a range of preclinical pain models. Our results indicated that the classical cannabinoid agonist WIN 55,212-2 produced supraspinal analgesia in preclinical pain models, which was selectively antagonized by the CB1 antagonist/inverse agonist AM251, but not by the CB2 antagonist AM630...

Opioids evoke analgesia through activation of opioid receptors (predominantly the μ opioid receptor) in the central nervous system. Opioid receptors are abundant in multiple regions of the central nervous system and the peripheral nervous system including enteric neurons. Opioid-related adverse effects such as constipation, nausea, and vomiting pose challenges for compliance and continuation of the therapy for chronic pain management. In the post-operative setting opioid-induced depression of respiration can be fatal...

Kappa (κ) opioid receptor selective antagonists are useful pharmacological tools in studying κ opioid receptors and have potential to be used as therapeutic agents for the treatment of a variety of diseases including mood disorders and drug addiction. Arodyn (Ac[Phe1-3,Arg4,d-Ala8]Dyn A-(1-11)NH2) is a linear acetylated dynorphin A (Dyn A) analog that is a potent and selective κ opioid receptor antagonist (Bennett et al. J Med Chem 2002;45:5617-5619) and prevents stress-induced reinstatement of cocaine-seeking behavior following central administration (Carey et al...

BACKGROUND: Gaps in chronic disease management have led to calls for novel methods of interprofessional, team-based care. Population panel management (PPM), the process of continuous quality improvement across groups of patients, is rarely included in health professions training for physicians, nurses, or pharmacists. The feasibility and acceptance of such training across different healthcare professions is unknown. We developed and implemented a novel, interprofessional PPM curriculum targeted to diverse health professions trainees...

Chronic low back pain is challenging to treat. Minimal invasive neurostimulation therapies, such as subcutaneous peripheral nerve field stimulation (SPNS), improve pain relief and quality of life,. The goal of the present study was to assess the usefulness, safety, and efficacy of SPNS in patients with chronic low back pain (CLBP). Twenty-six consecutive patients with CLBP were prospectively included in the study. For trial neurostimulation, two electrodes were implanted vertically at a depth of 1 cm into the subcutaneous tissue, ≤ 10 cm from the region of maximum pain...

BACKGROUND AND PURPOSE: We previously showed that Nociceptin/orphanin FQ opioid peptide (NOP) receptor agonists attenuate the expression of levodopa-induced dyskinesia in animal models of Parkinson's disease. We now investigate the efficacy of two novel, potent and chemically distinct NOP receptor agonists, AT-390 and AT-403, to improve parkinsonian disabilities and attenuate dyskinesia development and expression. EXPERIMENTAL APPROACH: Binding affinity and functional efficacy of AT-390 and AT-403 at the opioid receptors were determined in radioligand displacement assays and in GTPγS binding assay respectively, conducted in Chinese hamster ovary cells...

OBJECTIVES: Unintentional opioid overdose deaths are a public health crisis, and naloxone is the most effective harm reduction tool to curb many of these deaths. There is growing evidence that take-home naloxone can prevent opioid overdose in targeted populations. The goal of this study is to measure the opioid overdose reversal rate with take-home naloxone among participants with a diagnosis of opioid use disorder (OUD) in an opioid treatment program (OTP) setting. METHODS: Patients enrolled in an outpatient OTP program were eligible for this prospective cohort study between April 4, 2016 and July 4, 2016...

Addressing the global obesity epidemic requires innovative approaches that are also acceptable to affected individuals. There is growing evidence suggesting that food addiction, one contributor to obesity, bears many similarities to drug and alcohol addiction, presenting a potential role for addiction-focused acupuncture as a novel treatment modality. In this perspective article, we begin by briefly reviewing the evidence linking food and drug/alcohol addiction. We then describe the development of an acupuncture-based protocol for treating opioid addiction in Hong Kong in the 1970s and discuss the evidence base for acupuncture's efficacy in treating a range of substance use disorders...

Novel substituted amino acid tethered norsufentanil derivatives were synthesized by the four-component Ugi reaction. Norsufentanil was reacted with succinic anhydride to produce the corresponding carboxylic acid. The resulting carboxylic acid has undergone a multicomponent reaction with different aldehydes, amines, and isocyanides to produce a library of the desired compounds. In all cases, amide bond rotation was observed in the NMR spectra. In vivo analgesic activity of the synthesized compounds was evaluated by a tail flick test...

Patients with sickle cell disease (SCD) suffer from intense pain that can start during infancy and increase in severity throughout life, leading to hospitalization and poor quality of life. A unique feature of SCD is vaso-occlusive crises (VOCs) characterized by episodic, recurrent, and unpredictable episodes of acute pain. Microvascular obstruction during a VOC leads to impaired oxygen supply to the periphery and ischemia reperfusion injury, inflammation, oxidative stress, and endothelial dysfunction, all of which may perpetuate a noxious microenvironment leading to pain...
