REVIEW
Fady Rachid
OBJECTIVE: Cocaine use disorder is a very common condition that represents a substantial public health problem, and no effective pharmacological or psychological therapies have been identified to date. Urgent therapeutic alternatives are therefore needed such as neurostimulation techniques. The purpose of this review is to describe and discuss studies that have evaluated the safety and efficacy of these techniques for the treatment of cocaine dependence. METHODS: The electronic literature on repetitive transcranial magnetic stimulation, theta-burst stimulation, deep transcranial magnetic stimulation, transcranial direct current stimulation, magnetic seizure therapy, electroconvulsive therapy, cranial electro-stimulation, and deep brain stimulation in the treatment of cocaine addiction were reviewed...

Even following long periods of abstinence, individuals with anxiety disorders have high rates of relapse to drugs of abuse. Although many current models of relapse demonstrate effects of acute stress on drug-seeking, most of these studies examine stressful experiences that occur in close temporal and physical proximity to the reinstatement test. Here, we assess the effects of a stressful experience in one context on fear and drug-seeking in a different context. We adapt the stress-enhanced fear learning procedure to examine impacts on drug-seeking long after the stressful experience occurred...

Cocaine addiction is a chronic relapsing disorder characterized by persistent perturbations to an organism's homeostatic processes that result in maladaptive drug seeking. Although considerable attention has been directed at the consequences of neuronal changes following chronic cocaine taking, few studies have examined the role of microglia, the brain's resident immune cells, following chronic cocaine administration. Toll-Like Receptor 4 (TLR4) is a molecular pattern receptor that recognizes pathogens, danger signals, and xenobiotics and induces proinflammatory signaling in the central nervous system...

BACKGROUND: In this study, we evaluated if the 120-hour distance-learning (DL) course SUPERA (an acronym in Portuguese meaning: System for detection of excessive use or dependence on psychoactive substances: brief Intervention, social reinsertion and follow-up) was an effective way to train health professionals and social workers to apply screening and brief intervention (SBI) for patients with substance use disorders. METHODS: In the first phase, 2,420 health professionals or social workers, who had completed the course, answered an online survey about their use of the SBI...

BACKGROUND: Highly caffeinated energy drinks (EDs) are popular with adolescents and young adults, but longitudinal consumption patterns are poorly understood especially in relation to other substance use. METHODS: ED and other substance use were assessed annually (modal ages 21-25) among a sample (n=1099) who were originally recruited as first-year college students (modal age 18). Trajectory groups were derived based on probability of past-year use during ages 21-24, and compared for possible differences in substance use outcomes at age 25, holding constant demographics, sensation-seeking, other caffeine consumption, and age 21 substance use...

Synthetic Cannabinoids are a street drug that is widely attainable and cheap compared to natural cannabis, and has variable potency and unpredictable effects with no commercially available diagnostic test to confirm its presence. Similar to natural cannabis, Synthetic Cannabinoid intoxication can present in several ways with the most common emergency room presentations to be of neurologic and psychiatric manifestation. The respiratory depressive effect of Synthetic Cannabinoids has not been well documented in medical literature...

BACKGROUND: Substance use disorder can increase the risk of suicide attempt. However, the relationship between substance use disorder and suicide attempt has yet to be explored among people who report compromised health, even though sick people are more likely to make an attempt. OBJECTIVES: Among people who report fair or poor health on the National Survey of Drug Use and Health (2006-2014; N = 502,467), I examined whether people with commonly occurring substance use disorders are more likely to attempt suicide than people without substance use disorders...

In prior research, having traits consistent with a personality disorder has been shown to be related to substance use and high-risk sexual activity; however, few studies have examined relationships between dependency traits and health-jeopardizing behaviors. Individuals with traits consistent with dependent personality disorder may be more likely to be in a primary relationship characterized by unhealthy conditions, including physical abuse from a partner, low assertiveness in sexual situations, and partner infidelity...

Glutamate and GABA play an important role in substance dependence. However, it remains unclear whether this holds true for different substance use disorders and how this is related to risk-related traits such as impulsivity. We, therefore, compared Glx (as a proxy measure for glutamate) and GABA concentrations in the dorsal anterior cingulate cortex (dACC) of 48 male cigarette smokers, 61 male smoking polysubstance users, and 90 male healthy controls, and investigated the relationship with self-reported impulsivity and substance use...

Depression and substance-abuse (e.g., use of cocaine) are disorders with a high frequency of comorbidity. In the present study, we combined bilateral olfactory bulbectomy (OBX), an animal model of depression, with intravenous cocaine self-administration and extinction/reinstatement in rats to investigate the effects of two antidepressant drugs, escitalopram (ESC) and imipramine (IMI), with the goal of determining whether these drugs altered cocaine-induced rewarding and seeking behaviors. Acutely administered ESC (2...

While the detrimental effects of concurrent substance use disorders (SUDs) are now being well documented, very few studies have examined this comorbidity among women with posttraumatic stress disorder (PTSD). Data for these analyses were derived from the "Women and Trauma" study conducted within the National Drug Abuse Treatment Clinical Trials Network. Women with full or subthreshold PTSD and co-occurring cannabis use disorder (CUD) and cocaine use disorder (COD; N=99) were compared to their counterparts with co-occurring CUD only (N=26) and co-occurring COD only (N=161) on rates of trauma exposure, psychiatric disorders, psychosocial problems, and other substance use utilizing a set of multivariate logistic regressions...

BACKGROUND: There are limited data about the extent of DSM-5 substance use disorders (SUDs) among primary care patients. METHODS: This study analyzed data from a multisite validation study of a substance use screening instrument conducted in a diverse sample of 2000 adults aged ≥18 years recruited from five primary care practices in four states. Prevalence and correlates of 12-month DSM-5 SUDs were examined. RESULTS: Overall, 75.5% of the sample used any substance, including alcohol (62...

Cocaine use disorder and post-traumatic stress disorder (PTSD) commonly co-occur. This could be due to vulnerability to post-traumatic symptoms conferred by previous exposure to cocaine. Therefore, we combined chronic binge-pattern cocaine with a model of psychological trauma (single prolonged stress) to determine whether the behavioral effects of psychological trauma are enhanced in cocaine-sensitized individuals. Adult male Sprague Dawley rats received 14 days of cocaine (15mg/kg/injection) or saline in a binge pattern (3 injections per day, 1h apart)...

OBJECTIVE: This study examines the impact of an insurance-mandated change in formulation of buprenorphine/naloxone (BNX) for patients with opioid use disorder treated in a primary care clinic. METHODS: A retrospective cohort study was conducted to determine the proportion of patients who were switched back to the previous BNX formulation and rates of aberrant urine drug tests for the 3 months before and 3 months after a mandated change in BNX from the sublingual film to the rapidly dissolving tablet (BNX-RDT)...

Hypothalamic hypocretin (orexin) peptides mediate arousal, attention, and reward processing. Fibers containing orexins project to brain structures that govern motivated behavior, including the ventral tegmental area (VTA). A number of psychiatric conditions, including attention deficit hyperactivity disorder (ADHD) and substance use disorders, are characterized by deficits in impulse control, however the relationship between orexin and impulsive behavior is incompletely characterized. The effects of systemic or centrally administered orexin receptor (OXR) antagonists on measures of impulsive-like behavior in rats were evaluated using the five-choice serial reaction time task (5-CSRTT) and delay discounting procedures...

BACKGROUND: There are high levels of comorbidity between schizophrenia and substance use disorder, but little is known about the genetic etiology of this comorbidity. METHODS: We tested the hypothesis that shared genetic liability contributes to the high rates of comorbidity between schizophrenia and substance use disorder. To do this, polygenic risk scores for schizophrenia derived from a large meta-analysis by the Psychiatric Genomics Consortium were computed in three substance use disorder datasets: the Collaborative Genetic Study of Nicotine Dependence (ascertained for tobacco use disorder; n = 918 cases; 988 control subjects), the Collaborative Study on the Genetics of Alcoholism (ascertained for alcohol use disorder; n = 643 cases; 384 control subjects), and the Family Study of Cocaine Dependence (ascertained for cocaine use disorder; n = 210 cases; 317 control subjects)...

Although early aversive postnatal events are known to increase the risk to develop psychiatric disorders later in life, rarely they determine alone the nature and outcome of the psychopathology, indicating that interaction with genetic factors is crucial for expression of psychopathologies in adulthood. Moreover, it has been suggested that early life experiences could have negative consequences or confer adaptive value in different individuals. Here we suggest that resilience or vulnerability to adult cocaine sensitivity depends on a "triple interaction" between genetic makeup x early environment x later experience...

OBJECTIVE: This study examined patterns of violence victimization and aggression in both intimate partner and nonpartner relationships among U.S. military veterans using latent profile analysis to identify subtypes of violence involvement. METHOD: Participants were 839 substance use treatment-seeking veterans (93% male) from a large Veterans Affairs Medical Center who completed screening measures for a randomized controlled trial. RESULTS: Past-year violence involvement, including both intimate partner violence (IPV) and nonpartner violence (NPV), was common in the sample, although NPV occurred at somewhat higher rates...

No pharmacotherapies are approved for the treatment of cocaine use disorders (CUD). Behavioral treatments for CUD are efficacious for some individuals, but recovery rates from CUD remain low. Cognitive impairments in CUD have been linked with poorer clinical outcomes. Cognitive enhancing pharmacotherapies have been proposed as promising treatments for CUD. Atomoxetine, a norepinephrine transporter inhibitor, shows potential as a treatment for CUD based on its efficacy as a cognitive enhancer in other clinical populations and impact on addictive processes in preclinical and human laboratory studies...
