BACKGROUND: Suicide is a major public health concern and suicide attempts (SA) are frequent and burdensome in people suffering from substance use disorders (SUDs). In particular, serious SAs are a preoccupying form of attempt, which remain largely overlooked in these populations, especially regarding basic risk factors such as gender, addictive comorbidity and substance use patterns. Thus, we undertook a gender-specific approach to identify the risk factors for serious SAs in outpatients with multiple SUDs...

BACKGROUND: Social media has increasingly become a venue for health discourse and support, particularly for vulnerable individuals. This study examines user-generated content of an online Reddit community targeting individuals recovering from opiate addiction. METHODS: 100 Reddit posts and their comments were collected from the online community on August 19, 2016. Posts were qualitatively coded for opioid use disorder (OUD) criteria as outlined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), as well as other common themes...

Opiate addiction is now a major public health problem. Perinatal insults and exposure to opiates such as morphine in utero are well known to affect development of the hypothalamic-pituitary-adrenal axis of the offspring adversely and are associated with a higher risk of developing neurobehavioral problems. Oxycodone is now one of the most frequently abused pain killers during pregnancy; however, limited data are available regarding whether and how perinatal oxycodone exposure (POE) alters neurobehavioral outcomes of the offspring...

The Pain Management Task Force of the American College of Rheumatology published a report in 2010 highlighting pain management as a fundamental aspect of clinical practice, training and research. In the interim, the consideration of pain as a focus of attention of rheumatologists and rheumatology health professionals has become even more challenging than in 2010 because of the epidemic of opiate addiction and overdose death. The characterisation of categories of pain by mechanism (e.g., inflammation, joint degeneration, abnormalities of central pain processing) can help guide treatment...

BACKGROUND: Opioids are natural, semisynthetic, or synthetic substances that act on opioid receptors in the central nervous system. Clinically, they are prescribed for pain management. Opioid overdose (OOD) occurs when the central nervous system and respiratory drive are suppressed because of excessive consumption of the drug. Symptoms of OOD include drowsiness, slow breathing, pinpoint pupils, cyanosis, loss of consciousness, and death. Due to their addictive potential and easy accessibility opioid addiction is a growing problem worldwide...

PURPOSE OF REVIEW: This review is intended to help the headache physician think through and plan for management issues concerning the use of opioids. We ask the headache physician to consider if there are instances where prescribing or continuing prescriptions of opiates is plausible, and if so, how can the physician proceed as safely as possible. Our goal is to start a conversation regarding the inevitable encounter with a patient on opiates or requesting opiates. RECENT FINDINGS: The use of opiates in our society has reached a crisis in staggering death and addiction rates...

BACKGROUND AND OBJECTIVES: Data suggest individuals with substance use disorders (SUD) have high rates of attrition from treatment and exhibit impairments on measures of executive functioning (EF). The primary aim of this pilot study was to investigate if EF is associated with attrition from a 1 month intensive outpatient program (IOP) for SUD, and examine the feasibility of implementing the project. METHODS: Baseline neurocognitive functioning was assessed by the Cambridge Neuropsychological Test Automated Battery (CANTAB) and the self-reported Behavior Rating Inventory of Executive Functioning (BRIEF-A) questionnaire...

Buprenorphine is an opiate used for pain management and to treat opiate addiction. The cytokine leptin can modulate nociception, but the extent to which buprenorphine-induced antinociception varies as a function of leptin signaling has not been characterized. Four congenic mouse lines with phenotypes that include differences in body weight and leptin status were used to test the hypothesis that the antinociceptive effects of buprenorphine vary as function of sex and leptin signaling. Each mouse line was comprised of males (n=12) and females (n=12) for a total of 96 animals...

Opioid drugs, including prescription as well as heroin, have come to the national spotlight due to the unprecedented rate of overdose and addiction. The Centers for Disease Control and Prevention (CDC) has termed this problem as an "epidemic" that has reached record numbers of deaths in 2014. Approximately half of these deaths are the result from prescribed opioids. Also on the rise are the numbers of individuals who are diagnosed with chronic pain and are treated with opioids, methadone and buprenorphine. Individuals currently taking opioids for chronic pain confound the treatment of acute pain after traumatic injury...

Considering the pharmacological effects of chiral drugs, enantiopure drugs may differ from their racemic mixture formulation in efficacy, potency, or adverse effects. Levomethorphan (LVM) and Dextromethorphan (DXM) act on the central nervous system and exhibit different pharmacological features. LVM, the l-stereoisomer of methorphan, shows many similarities to opiates such as heroin, morphine and codeine, including the potential for addiction, while the d-stereoisomer, DXM, does not have the same opioid effect...

A total of 852 participants attending 11 centers for addiction treatment in north Italy following problems due to cocaine abuse between 1989 and 2013 were recruited. Two typologies were created: cocaine users (never heroin) (CU) and heroin and cocaine users (HCU). During the 38-year follow-up period, 4.8% of the whole cohort died. Over the whole period, tumors were the main causes of death; starting in 2010, suicide deaths became the first cause of death. Among CUs, most deaths were due to road accidents and suicide; among HCUs, most of the deaths were from opiate overdose and from cardio-circulatory system diseases...

Current treatments of opioid addiction include primarily maintenance medications such as methadone. Chronic exposure to opiate and/or long-lasting maintenance treatment induce modulations of gene expression in brain and peripheral tissues. There is increasing evidence that epigenetic modifications underlie these modulations. This review summarizes published results on opioid-induced epigenetic changes in animal models and in patients. The epigenetic modifications observed with other drugs of abuse often used by opiate abusers are also outlined...

INTRODUCTION: The diagnosis of psychoactive substance use disorders has been based primarily on descriptive, symptomatic checklist criteria. In opioid addiction, there are no objective biological indicators specific enough to guide diagnosis, monitor disease status, and evaluate efficacy of therapeutic interventions. Proton magnetic resonance spectroscopy ((1)H MRS) of the brain has potential to identify and quantify biomarkers for the diagnosis of opioid dependence. The purpose of this study was to detect the absolute glutamate concentration in the nucleus accumbens (NAc) of patients with prescription opioid dependence using (1)H MRS, and to analyze its clinical associations...

Orexin-A and -B neuropeptides are exclusively synthesized in hypothalamic neurons. These have been implicated to play critical roles in the expression of various behavioral manifestations such as feeding, arousal, wakefulness, drug dependence and tolerance. Orexin ligands activate orexin type-1 and orexin type-2 receptors each displaying a distinct selectivity and distribution profile. Orexinergic neurons innervate various brain structures among which the locus coeruleus (LC) and the lateral paragigantocellularis (LPGi) nuclei are well established as the two key mediators of opiate dependence and tolerance...

Opiate withdrawal/negative reinforcement has been implicated as one of the mechanisms for the progression from impulsive to compulsive drug use. Increase in the intracellular cAMP level and protein kinase A (PKA) activities within the neurocircuitry of addiction has been a leading hypothesis for opiate addiction. This increase requires the phosphorylation of μ-opioid receptor (MOR) at Tyr(336) by Src after prolonged opiate treatment in vitro Here, we report that the Src-mediated MOR phosphorylation at Tyr(336) is a prerequisite for opiate withdrawal in mice...

We are faced with a worldwide opiate/opioid epidemic that is devastating. According to the Centers for Disease Control and Prevention (CDC), at least 127 people, young and old, are dying every day in America due to narcotic overdose. The Food and Drug Administration (FDA) has approved Medication-Assisted Treatments (MATs) for opiate/opioids as well as alcohol and nicotine. The mechanism of action of most MATS favors either blocking of dopaminergic function or a form of Opiate Substitution Therapy (OST). These treatment options are adequate for short-term treatment of the symptoms of addiction and harm reduction but fail long-term to deal with the cause or lead to recovery...

The most powerful analgesic and addictive properties of opiate alkaloids are mediated by the μ opioid receptor (MOR). The MOR has been extensively investigated as a drug target in the twentieth century, with numerous compounds of varying efficacy being identified. We employed molecular dynamics and Gaussian accelerated molecular dynamics techniques to identify the binding mechanisms of MORs to BU72 (agonist) and β-funaltrexamine (antagonist). Our approach theoretically suggests that the 34 residues (Lys209-Phe221 and Ile301-Cys321) of the MORs were the key regions enabling the two compounds to bind to the active site of the MORs...

In August 2016, U.S. Surgeon General Vivek Murthy, MD, MBA, issued a letter to healthcare providers requesting aid in addressing "an urgent health crisis facing America: the opioid epidemic." In this article, we address some of the more poignant challenges that surface in treating patients with opiate addiction. We provide an outline of recommendations from the leading medical organizations to educate primary care providers on how to navigate patients to decreased or discontinued medication loads.

Opioids are among the most effective pain relievers; however, their abuse has been on the rise worldwide evident from an alarming increase in accidental opioid overdoses. This demands for an urgent increase in scientific endeavors for better understanding of main cellular mechanisms and circuits involved in opiate addiction. Preclinical studies strongly suggest that memories associated with positive and negative opioid experiences are critical in promoting compulsive opiate-seeking and opiate-taking behaviors, and relapse...
