Opioid use disorders (OUDs) are a growing problem in the United States. When OUDs co-occur with problematic drinking and posttraumatic stress disorder (PTSD), negative drug-related mental and physical health outcomes may be exacerbated. Thus, it is important to establish whether PTSD treatments with established efficacy for dually diagnosed individuals also demonstrate efficacy in individuals who engage in problematic drinking and concurrent opioid misuse. Adults who met DSM-IV-TR criteria for PTSD and alcohol dependence were recruited from a substance use treatment facility and were randomly assigned to receive either modified prolonged exposure (mPE) therapy for PTSD or a non-trauma-focused comparison treatment...

A Kuo, M T Smith
Outbred rodent stocks including Sprague Dawley rats, are known for their genetic diversity and so they are often used to develop animal models of human disease. Although between-colony differences in pharmaco-behavioural studies have been published previously, a direct head-to-head comparison study, whereby all research was performed in the same laboratory by the same experimenter utilising the supraspinal route of drug administration in the same strain of rat, is lacking. Herein, we report our head-to-head comparison study, involving assessment of antinociception, constipation and respiratory depression evoked by single bolus intracerebroventricular (ICV) doses of morphine, buprenorphine, DPDPE and U69,593 using male Sprague Dawley rats sourced from a different breeding colony (BC2) from that (BC1) used by us previously...

Epidermolysis bullosa is a rare blistering skin disorder that is challenging to manage because skin fragility and repeated wound healing cause itching, pain, limited mobility, and recurrent infections. Cannabidiol, an active cannabinoid found in cannabis, is postulated to have antiinflammatory and analgesic effects. We report 3 cases of self-initiated topical cannabidiol use in patients with epidermolysis bullosa in an observational study. One patient was weaned completely off oral opioid analgesics. All 3 reported faster wound healing, less blistering, and amelioration of pain with cannabidiol use...

AIM: Methadone is a long-acting opioid receptor agonist. It is prescribed to patients with opioid-related use disorders. The OPRM1 gene encodes for methadone's main receptor. It appears that polymorphisms in OPRM1 may affect the efficacy of methadone maintenance treatment (MMT). OBJECTIVE: Our purpose was to identify all relevant published papers dealing with the impact ofOPRM1's SNPs  on MMT's efficacy and to summarize results in order to evaluate the relevance of conducting pretherapeutic genotyping in opioid addicts prior to the onset of MMT...

RATIONALE: Pain is the leading reason for seeking health care, and mu opioid receptor agonists continue to be prescribed despite well-documented adverse effects. Kappa opioid receptor agonists have antinociceptive effects with little to no abuse liability and might be useful for treating pain in mixtures. Kappa:mu opioid mixtures might be useful if therapeutic effects of each drug can be selectively increased while reducing or avoiding the adverse effects that occur with larger doses of each drug alone...

Purpose: There is an increasing interest in the identification of predictors for individual responses to analgesics and surgical pain. In this study, we aimed to determine psychological factors that might contribute to this response. We hence investigated patients undergoing a standardized surgical intervention (open nephrectomy). Patients and methods: Between May 2014 and April 2015, we conducted a prospective observational cohort study. The following psychological tests were administered preoperatively: Mini-Mental State Examination, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, and Pain Catastrophizing Scale...

BACKGROUND AND OBJECTIVES: Quadratus lumborum block was first described in 2007 and currently there are descriptions of its achievement through four different injection points. This blockage provides abdominal wall and visceral analgesia, and one of its mechanisms is the dispersion of the local anesthetic into the paravertebral space. We describe the performance of a continuous quadratus lumborum type II block for postoperative analgesia in a partial nephrectomy. CASE REPORT: A 64-year-old woman, scheduled for partial left laparoscopic nephrectomy...

Treatment of opioid use disorder often begins with brief intensive inpatient or outpatient programs. Given the high relapse rates following intensive treatment, it is important to determine factors that lead to success post-discharge. Incorporating assessment during and early post-discharge may help determine such factors. The current study evaluated changes in quality of life among individuals during and after discharge from inpatient and partial hospitalization opiate treatment programs. Participants (n = 143) were recruited while in the programs and were re-assessed one month later (n = 113)...

Limited information is available regarding the efficacy of opioid analgesics in chinchillas. Here we sought to evaluate the analgesic efficacy and safety of hydromorphone in chinchillas. In a randomized, controlled, blind, complete crossover design, hydromorphone was administered at 0.5, 1, and 2 mg/kg SC to 16 chinchillas. Analgesic efficacy was determined by measuring hindlimb withdrawal latencies after a thermal noxious stimulus (Hargreaves method) at 0, 1, 2, 4, and 8 h after drug administration. Changes in daily food intake and fecal output after hydromorphone administration were recorded...

Adaptations within the nucleus accumbens (NAc) and caudate nucleus (CN) dopamine neurotransmission are involved in behavioral sensitization and enhanced incentive motivation towards drug paired stimuli which lead to drug addiction. Serotonin (5-hydroxytryptamine; 5-HT) can modulate dopamine neurotransmission to reduce rewarding effects of drugs of abuse. A recent study from our laboratory shows that rewarding effects of morphine are inhibited in rats co-treated with buspirone. To understand the neurochemical mechanism involved in morphine addiction and its inhibition with buspirone, present study determines the effects of buspirone, morphine and their co-administration on the metabolism of serotonin and dopamine in the NAc and CN...

The present study aimed to investigate the role of quaternary ammonium salt of U50,488H (Q-U50,488H) in hypoxic pulmonary hypertension (HPH) and underlying mechanisms involved. A HPH animal model was established in rats under hypoxia and the mean pulmonary arterial pressure (mPAP) and right ventricular pressure (RVP) were measured. Relaxation of the pulmonary artery in response to Q-U50,488H was determined. In addition, expression and activity of endothelial nitric oxide (NO) synthase (eNOS) and inducible NO synthase (iNOS) with NO content, Akt expression, total antioxidant capacity (T-AOC), and gp91phox were evaluated...

BACKGROUND: Endogenous opioids, enkephalins, are known to increase with acute kidney injury. Since the mature pentapeptides are unstable, we evaluated the performance of an assay that measures proenkephalin 119-159 (PENK), a stable peptide formed concomitantly with mature enkephalins. METHODS: PENK assay performance was evaluated on two microtiterplate/chemiluminescence sandwich immunoassay formats that required 18 or 1 h incubation times. PENK concentration was measured in plasma from healthy individuals to establish a reference interval and in patients with varied levels of kidney function and comorbidities to assess the association with measured glomerular filtration rate (mGFR) using iothalamate clearance...

The ventral tegmental area (VTA) is the origin of the mesolimbic dopaminergic system known to play an integral role in mediating reward and development of drug addiction. Although the differences in neuronal plasticity of VTA at various ages remain to be understood, age is known to influence the effects of chronic opioids. In addition, adaptations associated with exposure to opioids within glial populations located in the VTA are poorly understood. The objective of the study was to determine if there are changes in astrocytic immunofluorescent labeling in the VTA following chronic morphine administration in a rat model at different ages: newborn at postnatal day (PD)7 and adult (estimated PD57)...

BACKGROUND: Process measure compliance has been associated with improved outcomes in enhanced recovery after surgery (ERAS) programs. Herein, we sought to assess the impact of compliance with measures directly influenced by anesthesiology in an ERAS for colorectal surgery cohort. METHODS: From January 2013 to April 2015, data from 1140 consecutive patients were collected for all patients before (pre-ERAS) and after (ERAS) implementation of an ERAS program. Compliance with 9 specific process measures directly influenced by the anesthesiologist or acute pain service was analyzed to determine the impact on hospital length of stay (LOS)...

The mixed-action κ-opioid receptor (KOR) agonist, pentazocine, binds to both KOR and the µ-opioid receptor (MOR). Racemic (±)-pentazocine and (-)-pentazocine, each administered systemically, have been shown to produce antinociception in various animal models. In contrast, racemic (±)-pentazocine failed to produce antinociception when administered intrathecally (i.t.). However, whether spinal activation of KOR and MOR by (-)-pentazocine produces antinociception and the relative contribution of KOR and MOR in mediating antinociception remain unknown...

Many malignant cancers, including breast cancer, have a propensity to invade bones, leading to excruciating bone pain. Opioids are the primary analgesics used to alleviate this cancer-induced bone pain (CIBP) but are associated with numerous severe side effects, including enhanced bone degradation, which significantly impairs patients' quality of life. In contrast, agonists activating only peripheral CB1 receptors (CB1Rs) have been shown to effectively alleviate multiple chronic pain conditions with limited side effects, yet no studies have evaluated their role(s) in CIBP...

Pain and fatigue are the most common problems reported by women in the early postpartum period. Pain can interfere with a woman's ability to care for herself and her infant. Untreated pain is associated with a risk of greater opioid use, postpartum depression, and development of persistent pain. Nonpharmacologic and pharmacologic therapies are important components of postpartum pain management. Because 81% of women in the United States initiate breastfeeding during the postpartum period, it is important to consider the drug effects of all prescribed medications on the mother-infant dyad...
