COMPARATIVE STUDY
A J Greenshaw
beta-Phenylethylamine is an endogenous brain amine which has been characterised as an endogenous amphetamine. The rewarding properties of the structurally similar drug amphetamine in humans and other species indicate a possible role for endogenous beta-phenylethylamine in neural processes underlying reward or reinforcement. Evidence for reinforcing properties of beta-phenylethylamine in the drug self-administration and place preference paradigms is briefly reviewed. The possibility that endogenous beta-phenylethylamine may be involved in reinforcement processes is also considered in relation to studies of intracranial self-stimulation...

The sleeping brain exhibits characteristic slow-wave activity which decays over the course of the night. This decay is thought to result from homeostatic synaptic downscaling. Transcranial electrical stimulation can entrain slow-wave oscillations (SWO) in the human electro-encephalogram (EEG). A computational model of the underlying mechanism predicts that firing rates are predominantly increased during stimulation. Assuming that synaptic homeostasis is driven by average firing rates, we expected an acceleration of synaptic downscaling during stimulation, which is compensated by a reduced drive after stimulation...

Agmatine (1-amino-4-guanidinobutane), a precursor for polyamine biosynthesis, has been identified as an important neuromodulator with anticonvulsant, antineurotoxic and antidepressant actions in the brain. In this context it has emerged as an important mediator of addiction/satiety pathways associated with alcohol misuse. Consequently, the regulation of the activity of key enzymes in agmatine metabolism is an attractive strategy to combat alcoholism and related addiction disorders. Agmatine results from the decarboxylation of L-arginine in a reaction catalyzed by arginine decarboxylase (ADC), and can be converted to either guanidine butyraldehyde by diamine oxidase (DAO) or putrescine and urea by the enzyme agmatinase (AGM) or the more recently identified AGM-like protein (ALP)...

Kratom is an herb indigenous to Southeast Asia with psychoactive opioid compounds, often used as a treatment for chronic pain or opiate withdrawal symptoms. It is legally and readily available via Internet sales and has been identified as an emerging drug of abuse in the United States. Kratom use has been associated with psychosis, seizures, and even death. At lower doses, kratom acts as a stimulant, while at higher doses, it produces analgesia and euphoria. Here, we describe the successful management of kratom overdose and withdrawal in a young man with negative toxicology screens...

REVIEW
Elson Asevedo, Ana C Mendes, Michael Berk, Elisa Brietzke
OBJECTIVE: To conduct the first systematic literature review of clinical trials of N-acetylcysteine (NAC) for the treatment of substance abuse disorders and addictive behaviors. METHODS: A search of the MEDLINE, Embase and PsycINFO databases was conducted. The inclusion criteria for the review were clinical trials that used NAC in the treatment of a disorder related to substance use and/or addictive behaviors, limited to texts in English, Spanish, or French. The selected studies were evaluated with respect to type of trial, sample size, diagnostic input, intervention, length of follow-up, outcome variables, and results...

The aversive effect of nicotine withdrawal is greater in female versus male rats, and we postulate that this sex difference is mediated in the nucleus accumbens (NAc). Nicotine withdrawal induces decreases in NAc dopamine and increases in acetylcholine (ACh) levels in male rats. To our knowledge, these neurochemical markers of nicotine withdrawal have not been compared in female versus male rats. Given the role of amino acids in modulating NAc dopaminergic and cholinergic transmission, concomitant measures of gamma-aminobutyric acid (GABA) and glutamate levels were also compared across sex...

UNLABELLED: Dependence is a hallmark feature of opiate addiction and is defined by the emergence of somatic and affective withdrawal signs. The nucleus accumbens (NAc) integrates dopaminergic and glutamatergic inputs to mediate rewarding and aversive properties of opiates. Evidence suggests that AMPA glutamate-receptor-dependent synaptic plasticity within the NAc underlies aspects of addiction. However, the degree to which NAc AMPA receptors (AMPARs) contribute to somatic and affective signs of opiate withdrawal is not fully understood...

Jennifer Kaufling, Gary Aston-Jones
UNLABELLED: Protracted opiate withdrawal is accompanied by altered responsiveness of midbrain dopaminergic (DA) neurons, including a loss of DA cell response to morphine, and by behavioral alterations, including affective disorders. GABAergic neurons in the tail of the ventral tegmental area (tVTA), also called the rostromedial tegmental nucleus, are important for behavioral responses to opiates. We investigated the tVTA-VTA circuit in rats after chronic morphine exposure to determine whether tVTA neurons participate in the loss of opiate-induced disinhibition of VTA DA neurons observed during protracted withdrawal...

The increasing number of opioid users among chronic pain patients, and opioid abusers among the general population, makes perioperative pain management challenging for health care professionals. Anesthesiologists, surgeons, and nurses should be familiar with some pharmacological phenomena which are typical of opioid users and abusers, such as tolerance, physical dependence, hyperalgesia, and addiction. Inadequate pain management is very common in these patients, due to common prejudices and fears. The target of preoperative evaluation is to identify comorbidities and risk factors and recognize signs and symptoms of opioid abuse and opioid withdrawal...

The interaction of neurotransmitters and genes that control the release of dopamine is the Brain Reward Cascade (BRC). Variations within the BRC, whether genetic or epigenetic, may predispose individuals to addictive behaviors and altered pain tolerance. This discussion authored by a group of concerned scientists and clinicians examines the Genetic Addiction Risk Score (GARS), the first test to accurately predict vulnerability to pain, addiction, and other compulsive behaviors, defined as Reward Deficiency Syndrome (RDS)...

REVIEW

Ketamine is a non-competitive antagonist at the N-methyl-d-aspartate receptor. It has recently been found to have antidepressant effects and is a drug of abuse, suggesting it may have dopaminergic effects. To examine the effect of ketamine on the dopamine systems, we carried out a systematic review and meta-analysis of dopamine measures in the rodent, human and primate brain following acute and chronic ketamine administration relative to a drug-free baseline or control condition. Systematic search of PubMed and PsychInfo electronic databases yielded 40 original peer-reviewed studies...

BACKGROUND: Among several potential neuroanatomical targets pursued for deep brain stimulation (DBS) for treating those with treatment-resistant depression (TRD), the superolateral-branch of the medial forebrain bundle (MFB) is emerging as a privileged location. We investigated the antidepressant-like phenotypic and chemical changes associated with reward-processing dopaminergic systems in rat brains after MFB-DBS. METHODS: Male Wistar rats were divided into three groups: sham-operated, DBS-Off, and DBS-On...

BACKGROUND AND AIMS: Methamphetamine dependence is associated with heightened impulsivity and diminished quality of life, but the link between impulsivity and changes in quality of life during treatment has not been examined. We aimed to investigate how different elements of impulsivity predict change in quality of life in the 6 weeks after engaging in treatment. DESIGN: Longitudinal, observational cohort study. SETTING: Public and private detoxification and rehabilitation facilities in metropolitan Melbourne, Australia...

Wayne Hall, Malcolm Parker
The recent practice in Belgium and the Netherlands of accepting addiction as a reason for performing euthanasia raises important issues for the field of addiction and the practice of euthanasia. In this paper we outline some of these issues. We also argue that physicians making decisions about whether to accept requests for euthanasia from people with an allegedly untreatable addiction should consider two issues carefully. They should ensure that: (1) the person has the capacity to give free and informed consent to undergo euthanasia; and (2) their request is the outcome of a deliberative process in which all reasonable treatment options and harm reduction measures have been offered to and considered by the person...

#16
Michael T Bowen, Inga D Neumann
The neuropeptide oxytocin is released both into the blood and within the brain in response to reproductive stimuli, such as birth, suckling and sex, but also in response to social interaction and stressors. Substance use disorders, or addictions, are chronic, relapsing brain disorders and are one of the major causes of global burden of disease. Unfortunately, current treatment options for substance use disorders are extremely limited and a treatment breakthrough is sorely needed. There is mounting preclinical evidence that targeting the brain oxytocin system may provide that breakthrough...

REVIEW
Kendall D Jeynes, E Leigh Gibson
BACKGROUND: Nutrition is a prerequisite for health; yet, there is no special nutritional assessment or guidance for drug and alcohol dependent individuals, despite the fact that their food consumption is often very limited, risking malnutrition. Further, the premise is examined that malnutrition may promote drug seeking and impede recovery from substance use disorders (SUD). METHOD: A narrative review addressed the relationship between substance use disorders and nutrition, including evidence for malnutrition, as well as their impact on metabolism and appetite regulation...

REVIEW
Katherine Rudzinski, Peggy McDonough, Rosemary Gartner, Carol Strike
Research in the area of illicit substance use remains preoccupied with describing and analyzing the risks of people who use drugs (PWUD), however more recently there has been a drive to use a strengths-based or resilience approach as an alternative to investigating drug use. This leads us to ask: what can be known about PWUD from the point of view of resilience? The objective of this scoping review is to analyze how the concept of resilience is defined, operationalized, and applied in substance use research...

Li-Min Mao, Qiang Wang
Protein phosphorylation is an important posttranslational modification of group I metabotropic glutamate receptors (mGluR1 and mGluR5 subtypes) which are widely distributed throughout the mammalian brain. Several common protein kinases are involved in this type of modification, including protein kinase A, protein kinase C, and extracellular signal-regulated kinase. Through constitutive and activity-dependent phosphorylation of mGluR1/5 at specific residues, protein kinases regulate trafficking, subcellular/subsynaptic distribution, and function of modified receptors...

Drug addiction treatment medications available nowadays are limited in both efficacy and number. The increased understanding of drug addiction circuitries leads the scientific community to look for better molecules and targets for detoxification and relapse prevention. This review focus on known targets (e.g., metabotropic glutamate receptor 5 and GABAB receptor) and on novel potential treatment acting on oxytocin system, which interacts with diverse neurotransmitters, has proved successful in both preclinical and clinical studies on ethanol, cocaine and methamphetamine...
