[Substance abuse and cardiovascular risk: cocaine].

G Ital Cardiol (Rome) 2022 Jun;23(6):444-453

U.O.C. Cardiologia, P.O. San Filippo Neri, ASL Roma 1, Roma.

Cocaine abuse is widely increasing, especially in younger individuals. Cocaine is a major cause of chest pain and acute coronary syndrome and is the leading cause for drug abuse-related visits to emergency departments, most of which are due to cardiovascular complaints. Cocaine use, especially long-term, is associated with an increased risk of all-cause mortality, and with several significant, life-threatening cardiovascular diseases although the multifactorial underlying cellular and molecular pathophysiological mechanisms of acute and chronic cocaine cardiotoxicity are not well established due to limited studies.

Cannabis and cocaine use, drinking outcomes, and quality of life in general hospital inpatients with alcohol use disorder.

Subst Abus 2022 ;43(1):1225-1230

Department of Community Health Sciences, Boston University School of Public Health, Boston, MA, USA.

While associations between cannabis and cocaine use, and heavy drinking and quality of life (QOL), are well-established in the general population, it is unclear whether they are present in hospital inpatients with alcohol use disorder (AUD). The aim of the study was to assess associations between cannabis and cocaine use and two outcomes [heavy drinking days (HDDs) and QOL] among hospital inpatients with AUD. Hospitalized patients with AUD and at least one past-month HDD participated in this cross-sectional study. Read More

Correlates of cannabis use disorder in the United States: A comparison of logistic regression, classification trees, and random forests.

J Psychiatr Res 2022 Jul 23;151:590-597. Epub 2022 May 23.

School of Social Work, Boston College, Chestnut Hill, MA, 02467, United States.

Although several recent studies have examined psychosocial and demographic correlates of cannabis use disorder (CUD) in adults, few, if any, recent studies have evaluated the performance of machine learning methods relative to standard logistic regression for identifying correlates of CUD. The present study used pooled data from the 2015-2018 National Survey on Drug Use and Health to evaluate psychosocial and demographic correlates of CUD in adults. In addition, we compared the performance of logistic regression, classification trees, and random forest methods in classifying CUD. Read More

Outcomes in Patients With Heart Failure Using Cocaine.

Am J Cardiol 2022 Aug 23;176:66-72. Epub 2022 May 23.

Division of Cardiology, San Francisco General Hospital, Department of Medicine, University of California, San Francisco, California.

Cocaine is an established cardiovascular toxin, but the impact of cocaine use on clinical outcomes in heart failure (HF) remains unknown. Although nonselective β-blocker use in cocaine users with HF and reduced ejection fraction (HFrEF) appears to be safely tolerated, selective β-blockers have not been evaluated. This study aimed to assess whether cocaine use is associated with worse clinical outcomes in patients with HF and evaluate the safety of β-blocker prescription upon discharge in cocaine users with HFrEF.

A serotonergic biobehavioral signature differentiates cocaine use disorder participants administered mirtazapine.

Transl Psychiatry 2022 05 6;12(1):187. Epub 2022 May 6.

Institute for Drug and Alcohol Studies, Virginia Commonwealth University, Richmond, VA, United States.

Cocaine use disorder (CUD) patients display heterogenous symptoms and unforeseeable responses to available treatment approaches, highlighting the need to identify objective, accessible biobehavioral signatures to predict clinical trial success in this population. In the present experiments, we employed a task-based behavioral and pharmacogenetic-fMRI approach to address this gap. Craving, an intense desire to take cocaine, can be evoked by exposure to cocaine-associated stimuli which can trigger relapse during attempted recovery. Read More

Cell Rep 2022 05;39(5):110775

Department of Physiology and Biophysics, University of California, Irvine, Irvine, CA 92617, USA; Department of Pharmaceutical Sciences, University of California, Irvine, Irvine, CA 92617, USA; Department of Biomedical Engineering, University of California, Irvine, Irvine, CA 92617, USA; Department of Neurobiology and Behavior, University of California, Irvine, Irvine, CA 92617, USA; Center for the Neurobiology of Learning and Memory, University of California, Irvine, Irvine, CA 92617, USA; UCI Mind, University of California, Irvine, Irvine, CA 92617, USA. Electronic address:

Although midbrain dopamine (DA) circuits are central to motivated behaviors, our knowledge of how experience modifies these circuits to facilitate subsequent behavioral adaptations is limited. Here we demonstrate the selective role of a ventral tegmental area DA projection to the amygdala (VTA→amygdala) for cocaine-induced anxiety but not cocaine reward or sensitization. Our rabies virus-mediated circuit mapping approach reveals a persistent elevation in spontaneous and task-related activity of inhibitory GABAergic cells from the bed nucleus of the stria terminalis (BNST) and downstream VTA→amygdala cells that can be detected even after a single cocaine exposure.

Effects of ketosis on cocaine-induced reinstatement in male mice.

Neurosci Lett 2022 05 5;778:136619. Epub 2022 Apr 5.

Unidad de Investigación Psicobiología de las Drogodependencias, Departamento de Psicobiología, Facultad de Psicología, Universitat de Valencia, Valencia, Spain. Electronic address:

In recent years, the benefits of the ketogenic diet (KD) on different psychiatric disorders have been gaining attention, but the substance abuse field is still unexplored. Some studies have reported that palatable food can modulate the rewarding effects of cocaine, but the negative metabolic consequences rule out the recommendation of using it as a complementary treatment. Thus, the main aim of this study was to evaluate the effects of the KD on cocaine conditioned place preference (CPP) during acquisition, extinction, and reinstatement. Read More

The impact of levamisole and alcohol on white matter microstructure in adult chronic cocaine users.

Addict Biol 2022 05;27(3):e13149

Neuroscience Center Zurich, University of Zurich and Swiss Federal Institute of Technology Zurich, Zurich, Switzerland.

Previous brain imaging studies with chronic cocaine users (CU) using diffusion tensor imaging (DTI) mostly focused on fractional anisotropy to investigate white matter (WM) integrity. However, a quantitative interpretation of fractional anisotropy (FA) alterations is often impeded by the inherent limitations of the underlying tensor model. A more fine-grained measure of WM alterations could be achieved by measuring fibre density (FD). Read More

Hormonal milieu drives economic demand for cocaine in female rats.

Neuropsychopharmacology 2022 Jul 25;47(8):1484-1492. Epub 2022 Mar 25.

Brain Health Institute, Rutgers University, Piscataway, NJ, 08854, USA.

There are substantial sex differences in drug abuse, and a key feature of cocaine addiction is pathologically high motivation for drug. We investigated the role of ovarian hormones on cocaine demand in female rats using a within-session threshold behavioral economics (BE) procedure, which allows us to compare motivation for drug across hormonal states and sex while controlling for differences in dose and intake. This approach quantifies demand elasticity (α) and free consumption (Q, consumption at null effort) to determine motivation for cocaine. Read More

Increased density and antagonistic allosteric interactions in A2AR-D2R heterocomplexes in extinction from cocaine use, lost in cue induced reinstatement of cocaine seeking.

Pharmacol Biochem Behav 2022 04 18;215:173375. Epub 2022 Mar 18.

Department of Neuroscience, Karolinska Institutet, Stockholm, Sweden. Electronic address:

Neurochemical studies were previously performed on the effects of a 10 day extinction learning from cocaine self-administration on D2R and A2AR recognition and D2R Gi/o coupling in the ventral striatum. In the present study biochemical receptor binding and proximity ligation assay were used to study possible changes in the allosteric receptor-receptor interactions and the density of the A2AR-D2R heterocomplexes in the ventral striatum (nucleus accumbens shell) in extinction from cocaine self-administration including cue induced reinstatement of cocaine seeking. A significant and clear-cut reduction of active lever pressing was observed in extinction on day 10 from cocaine use. Read More

Drug versus non-drug behaviors: A dual-reward model of sex differences and neurobiological mechanisms in rats.

J Exp Anal Behav 2022 05 17;117(3):457-471. Epub 2022 Mar 17.

Department of Neuroscience, Medical University of South Carolina.

Substance Use Disorders (SUDs) are an impactful problem characterized by chronic relapse and engagement in drug-related behaviors at the expense of non-drug behaviors. Brain regions implicated in drug and non-drug-related behaviors often overlap, complicating investigations of neurobiological mechanisms underlying SUDs. Here we presented a within-subject model for studying self-administration, reinforcer competition, extinction, and cued reinstatement of cocaine- and food-seeking in rats. Read More

Ca-permeable AMPA receptors set the threshold for retrieval of drug memories.

Mol Psychiatry 2022 Jun 16;27(6):2868-2878. Epub 2022 Mar 16.

Department of Psychiatry and Psychotherapy, University Medical Center, D-37075, Göttingen, Germany.

Frequent relapse prevents the successful treatment of substance use disorders and is triggered in part by retrieval of drug-associated memories. Drug-conditioned behaviours in rodents are reinstated upon drug memory retrieval following re-exposure to cues previously associated with the drug, or the drug itself. Therapies based on mechanistic insights from rodent studies have focused on amnesic procedures of cue-drug associations but with so far limited success. Read More

The Association Between Self-Reported Non-Injection Cocaine Use and Hepatitis C in the United States: An Analysis of the National Health and Nutrition Examination Survey.

J Stud Alcohol Drugs 2022 03;83(2):195-201

Division of Epidemiology, Dalla Lana School of Public Health, University of Toronto, Toronto, Ontario, Canada.

Objective: Previous studies conducted on hepatitis C virus (HCV) transmission have focused primarily on its transmission among people who inject drugs. However, there is evidence that transmission may also occur through the sharing of contaminated non-injection implements used to consume drugs nasally, orally, or by inhalation. Studies to date have not conclusively established a relationship between these routes of cocaine use and HCV. Read More

The relationship between craving and insular morphometry in regular cocaine users: Does sex matter?

Addict Biol 2022 03;27(2):e13157

Department of Clinical, Neuro and Developmental Psychology, Vrije University Amsterdam, Amsterdam, The Netherlands.

While it has been suggested that cocaine use and relapse in women is more strongly related to stress-relief craving, whereas cocaine use in men is more strongly related to reward craving, the neural mechanisms that underlie these differences are poorly understood. The aim of this study was to investigate sex-dependent differences in insular morphometry and associations with craving, in a sample of regular cocaine users (CUs) and non-drug using controls (non-CUs). It was hypothesized that insular volume, thickness and surface area would be lower in CU women, compared with CU men and non-CUs. Read More

Effects of acute and repeated administration of the selective M PAM VU0152099 on cocaine versus food choice in male rats.

Addict Biol 2022 03;27(2):e13145

McGovern Institute for Brain Research and Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA.

Ligands that stimulate muscarinic acetylcholine receptors 1 and 4 (M , M ) have shown promising effects as putative pharmacotherapy for cocaine use disorder in rodent assays. We have previously shown reductions in cocaine effects with acute M stimulation, as well as long-lasting, delayed reductions in cocaine taking and cocaine seeking with combined M /M receptor stimulation or with M stimulation alone. M stimulation opposes dopaminergic signalling acutely, but direct dopamine receptor antagonists have proved unhelpful in managing cocaine use disorder because they lose efficacy with long-term administration.
