BACKGROUND: Alcohol use has important adverse effects on people living with HIV (PLWH). This study of patients with recognized unhealthy alcohol use estimated and compared rates of alcohol-related care received by PLWH and HIV- patients. METHODS: Outpatients from the Veterans Health Administration who had one or more positive screen(s) for unhealthy alcohol use (AUDIT-C≥5) documented in their medical records 10/2009-5/2013 were eligible. Primary and secondary outcomes were brief intervention documented ≤14days after a positive alcohol screen, and a composite measure of any alcohol-related care (brief intervention, specialty addictions treatment or pharmacotherapy documented ≤365 days), respectively...

Understanding the brain circuitry that underlies reward is critical to improve treatment for many common health issues, including obesity, depression, and addiction. Here we focus on insights into the organization and function of reward circuitry and its synaptic and structural adaptations in response to cocaine exposure. While the importance of certain circuits, such as the mesocorticolimbic dopamine pathway, are well established in drug reward, recent studies using genetics-based tools have revealed functional changes throughout the reward circuitry that contribute to different facets of addiction, such as relapse and craving...

Addiction to medicines available over the counter or via prescription is of growing international concern. The authors of the current article ran an online survey of health professionals in general medical practice and community pharmacy settings in Northwest England to explore the frequency of suspecting and responding to addiction to medicines. Health professionals reported frequently identifying addiction to medicines among patients including those with long-term pain, mental health problems, sleep disorders, and other substance use disorders, but that these addictions often go unchallenged...

The increasing support for a dissociative subtype of post-traumatic stress disorder (PTSD-D) has led to its inclusion in DSM-5. We examined relationships between PTSD-D and relevant variables in patients with substance use disorders (SUD). The sample comprised N = 459 patients with SUD. The International Diagnostic Checklist and the Posttraumatic Diagnostic Scale were used to diagnose PTSD. In addition, participants completed the Childhood Trauma Questionnaire and the Dissociative Experiences Scale. The course of SUD was assessed by means of the European Addiction Severity Index...

The nature of addiction depends on various factors. The tendency to have already used several addictive substances and to seek high sensation experiences as a result of specific personality traits may lead to extreme and peculiar forms of addictions. Even belonging to specific social and cultural background may lead to such forms of addiction such as intentional snake bite and willful envenomation. In this article, we have discussed the peculiarities and practical insight of such addiction to snake venom. The possible molecular mechanism behind such venom-mediated reinforcement has also been highlighted...

Shati/Nat8L significantly increased in the nucleus accumbens (NAc) of mice after repeated methamphetamine (METH) treatment. We reported that Shati/Nat8L overexpression in mouse NAc attenuated METH-induced hyperlocomotion, locomotor sensitization, and conditioned place preference. We recently found that Shati/Nat8L overexpression in NAc regulates the dopaminergic neuronal system via the activation of group II mGluRs by elevated N-acetylaspartylglutamate following N-acetylaspartate increase due to the overexpression...

Opioids are the gold-standard treatment for severe pain. However, potentially life-threatening side effects decrease the safety and effectiveness of these compounds. The addiction liability of these drugs has led to the current epidemic of opioid abuse in the US. Extensive research efforts have focused on trying to dissociate the analgesic properties of opioids from their undesirable side effects. Splice variants of the mu opioid receptor (MOR), which mediates opioid actions, have unique pharmacological properties and anatomic distributions that make them attractive candidates for therapeutic pain relief...

Samantha M Fortin, Mitchell F Roitman
Drugs of abuse increase the frequency and magnitude of brief (1-3s), high concentration (phasic) dopamine release events in terminal regions. These are thought to be a critical part of drug reinforcement and ultimately the development of addiction. Recently, metabolic regulatory peptides, including the satiety signal glucagon-like peptide-1 (GLP-1), have been shown to modulate cocaine reward-driven behavior and sustained dopamine levels after cocaine administration. Here, we use fast-scan cyclic voltammetry (FSCV) to explore GLP-1 receptor (GLP-1R) modulation of dynamic dopamine release in the nucleus accumbens (NAc) during cocaine administration...

Thanks to advances in neuroscience, addiction is now recognized as a chronic brain disease with genetic, developmental, and cultural components. Drugs of abuse, including alcohol, are able to produce significant neuroplastic changes responsible for the profound disturbances shown by drug addicted individuals. The current lack of efficacious pharmacological treatments for substance use disorders has encouraged the search for novel and more effective pharmacotherapies. Growing evidence strongly suggests that Sigma Receptors are involved in the addictive and neurotoxic properties of abused drugs, including cocaine , methamphetamine , and alcohol...

OBJECTIVE: In recent decades, alexithymia has been considered a risk factor for multiple somatic and psychiatric conditions. Yet, whereas alexithymia has been extensively studied in adults with a substance misuse, only one study has reported data on cannabis abusers from the general population. Hence, our main objective was to explore alexithymia in a clinical sample of treatment-seeking young outpatients with a DSM-IV cannabis dependence or abuse diagnosis compared to controls. METHODS: 120 young patients (95 males - mean age 17...

Several neurobiological factors are related to opiate-use disorder (OUD), and among them, neurotrophins have a relevant role. Brain-derived neurotrophic factor (BDNF) is a central neurotrophin involved in many neuronal processes, and it has been related to several psychiatric diseases and addictive disorders. BDNF can be measured in plasma and serum; its levels may reflect BDNF concentrations in the central nervous system (CNS) and, indirectly, CNS processes. Hence, peripheral BDNF could be a biomarker in clinical practice...

Health care insurance plans covering treatment for substance use disorders (SUD) offer a wide range of benefits. Distinctions between health plan benefits are confusing, and consumers making selections may not adequately understand the characteristics or significance of the choices they have. The California Society of Addiction Medicine sought to help consumers make informed decisions about plan selections by providing education on the standard of care for SUD and presenting findings from an expert analysis of selected health plans...

This study examines aspects of prediction of suicide and death of undetermined intent. We investigated all consecutive, autopsied patients between 1993 and 1997 who had been in contact with the Addiction Centre in Malmö from 1968 onwards. The staff was asked, shortly after autopsy but before they knew of the manner of death, if they thought the patient had committed suicide. The case records were blindly evaluated, and toxicological autopsy findings for alcohol in blood samples investigated. The specificity of prediction was 83% and significantly more often correct than the sensitivity, which was only 45% for suicide and for suicide/death of undetermined intent (93% versus 39%)...

Alcoholism has been characterized as a systemic pro-inflammatory condition and alcohol withdrawal has been linked to various changes in the brain homeostasis, including oxidative stress and glutamate hyperactivity. N-acetylcysteine (NAC) is an anti-inflammatory and antioxidant multi-target drug with promising results in psychiatry, including drug addiction. We assessed the effects of NAC on the serum and brain inflammatory cytokines after cessation of chronic alcohol treatment in rats. Male Wistar rats received 2 g/kg alcohol or vehicle twice a day by oral gavage for 30 days...

Mu opioid receptor selective antagonists are highly desirable because of their utility as pharmacological probes for receptor characterization and functional studies. Furthermore, the mu opioid receptors act as an important target in drug abuse and addiction treatment. Previously, we reported NAP as a novel lead compound with high selectivity and affinity towards the mu opioid receptor. Based on NAP, we have synthesized its derivatives and further characterized their binding affinities and selectivity towards the receptor...

BACKGROUND: Eye Movement Desensitization and Reprocessing (EMDR) is an evidence-based treatment for PTSD. However, it is unclear whether EMDR shows the same effectiveness in patients with substance use disorders (SUD) and comorbid PTSD. In this trial, we examine the effectiveness of EMDR in reducing PTSD symptoms in patients with SUD and PTSD. METHODS/DESIGN: We conduct a single-blinded RCT among 158 patients with SUD and comorbid PTSD admitted to a German addiction rehabilitation center specialized for the treatment of patients with SUD and comorbid PTSD...

Recently high-resolution, noninvasive, multimodality in-vivo molecular imaging with PET, SPECT, CT and MRI, employing fusion algorithms has revolutionized personalized medicine. However, specific radiopharmaceuticals (RPs) for the accurate diagnosis and effective treatment of progressive neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, drug addiction, and other cognitive impairments still remain in developmental phase. Currently, multimodality fusion neuroimaging is utilized for the determination of: pharmacokinetics and pre-clinical development of radiopharmaceuticals (RPs); in-vivo monitoring of stem cell transplantation therapy; nicotinic acetylcholine receptors (nAChRs) investigations; and regional cerebral blood flow and glucose metabolism in cognitively-impaired subjects employing noninvasive microPET and nano-SPECT imaging...
