Hagit Bonny-Noach, Moran Sagiv-Alayoff
Background: Research conducted on young Israeli travellers has pointed to high substance usage rates. For some drug-using backpackers, actual extraction and rescue from their trip abroad is necessary. This study represents a first attempt to explore the influence of geographic region in which rescue occurs, cause for rescue and gender and age differences among Israeli rescuees. Methods: Sub-analysis of all logs of individual rescuees during a 5-year period from 2011 to 2016 ( N  = 86) included 66 men and 20 women, with an average age of 27...

PURPOSE: Long-acting injectable antipsychotics (LAI) can optimize adherence for high-risk serious mental illness (SMI). This customized adherence-enhancement approach delivered by social worker interventionists was combined with LAI (CAE-L) of paliperidone palmitate for homeless, poorly adherent individuals with SMI. METHODS: This 6-month prospective, uncontrolled trial of CAE-L in 30 recently homeless individuals with SMI assessed adherence using the Tablets Routine Questionnaire, injection frequency, and SMI symptoms measured by the Positive and Negative Syndrome Scale, Brief Psychiatric Rating Scale, and Clinical Global Impressions...

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)...

Drugs and food both exert a rewarding effect through the firing of dopamine neurons in the ventral tegmental area, resulting in the release of dopamine into the nucleus accumbens and effects on the mesolimbic pathway. Here, we review the neuroimaging literature to consider the validity of food addiction and the common neurobiological mechanisms that overlap in food and drug addiction. This review paper focuses on findings from Positron Emission Tomography (PET), functional Magnetic Resonance Imaging (fMRI) and structural imaging studies, as well as evidence from neuroimaging studies of bariatric surgery and pharmacological interventions on obese individuals...

OBJECTIVE: In mammals, intimate interactions exist between the circadian system and other molecular systems, and mounting evidence is suggesting that these relationships may affect substance use disorders. Research in preclinical models supports the role of circadian genes as risk factors for addiction. Here, we explore the evidence and review human genetic studies testing the association between specific circadian genes and substance use disorders. METHOD: A literature search was conducted in PubMed for studies testing variants in eight circadian genes known to be central to the functioning of the master clock in the brain...

BACKGROUND: A patient's health in an opioid maintenance program is potentially endangered due to concurrent consumption of drugs. Therefore, the German Medical Association requests evidence of compliant substitute intake while type and frequency of drug screening is chosen by the physician. This study comparatively assessed the feasibility and potential advantage of oral fluid drug testing versus urine screening in day-to-day practice. METHODS: Urine and oral fluid-samples of a randomly chosen third of a total of 361 patients, treated in four different practices in a major German city, were tested...

Poor decision-making is a central feature of all substance use disorders (SUD), but substances vary in the legal and health consequences associated with their use. For example, while the negative health consequences associated with cigarette smoking are often years away, the consequences of heroin abuse can be fatal in mere hours. It remains unclear if users of these substances show decision-making patterns that differ with the relative riskiness of their drug of choice. To address this question, we reviewed studies that compared decision-making of individuals using different substances...

PURPOSE: This phase 1, randomized, double-blind, placebo- and active comparator-controlled crossover study assessed the abuse potential of the antiepileptic drug, lacosamide. METHODS: After a qualification phase, 38 healthy, recreational central nervous system-depressant users were randomized to treatment sequences comprising single oral therapeutic (200 mg) and supratherapeutic (800 mg) doses of lacosamide, alprazolam (1.5 and 3 mg), and placebo. Subjective effects were assessed for 24 hours following each dose using a range of scales, with a 5- to 9-day washout between treatments...

INTRODUCTION: Phosphodiesterase type 5 inhibitors (PDE5Is) have demonstrated efficacy in the treatment of erectile dysfunction (ED). Although historically found to have limited drug-related adverse events, emerging data have suggested that PDE5Is might be associated with melanoma or recurrence of prostate cancer after radical prostatectomy. AIM: To summarize the literature on the safety of PDE5Is. METHODS: A literature review was performed through PubMed from 1990 through 2016 regarding ED...

BACKGROUND: HIV persists as a public health emergency in South Africa, especially among women of childbearing age. In response to the HIV epidemic, the Joint United Nations Programme on HIV/AIDS has put forth the 90-90-90 global goals to achieve an AIDS-free generation by 2020. This goal aspires to have 90% of people living with HIV diagnosed; 90% of those who test positive on sustained antiretroviral therapy (ART); and 90% of those on ART be virally suppressed. Ensuring access to ART is an important first step in reducing HIV incidence, especially among vulnerable populations such as women who use substances and bear the burden of HIV in South Africa...

PURPOSE: Rural communities are currently being impacted by a nationwide epidemic of prescription opioid misuse. Rural adolescent substance users may be at substantial risk for later addiction to these and other drugs. METHODS: This study uses Latent Class Analysis to identify subtypes of polysubstance users among a sample of 7,074 rural adolescents. Separate models were estimated for middle- and high-school youth. Predictive validity was estimated using cumulative ordinal logistic regression of the classes on a set of youth and family characteristics...

Cocaine is a recreational drug of abuse that binds to the dopamine transporter (DAT), preventing reuptake of dopamine into presynaptic terminals. The increased presence of synaptic dopamine results in stimulation of both pre- and postsynaptic dopamine receptors, considered an important mechanism by which cocaine elicits its reinforcing properties. However, the effects of acute cocaine administration on presynaptic dopamine function remain unclear. Non-invasive imaging techniques such as positron emission tomography (PET) have revealed impaired presynaptic dopamine function in chronic cocaine users...

BACKGROUND AND PURPOSE: There is a paucity of data on persistence of secondary prevention medications among stroke survivors in resource-limited settings where stroke is on a rapid upward trajectory and its management severely challenged. To avert new cardiovascular events after stroke, preventive medications should be promptly instituted and used continuously. We report 1-year rates and determinants of persistent utilization of secondary prevention therapies after stroke in Ghana. METHODS: A retrospective observational study involving 418 stroke survivors enrolled into a Neurology clinic in a tertiary institution in central Ghana between January 2011 and December 2013...

INTRODUCTION: Alcohol, tobacco, and illegal drug usage is pervasive throughout the world, and abuse of these substances is a major contributor to the global disease burden. Many pharmacotherapies have been developed over the last 50years to target addictive disorders. While the efficacy of these pharmacotherapies is largely recognized, their cognitive impact is less known. However, all substance abuse disorders are known to promote cognitive disorders like executive dysfunction and memory impairment...

Downregulation of the astroglial glutamate transporter GLT-1 is observed in the nucleus accumbens (NAc) following administration of multiple drugs of abuse. The decrease in GLT-1 protein expression following cocaine self-administration is dependent on both the amount of cocaine self-administered and the length of withdrawal, with longer access to cocaine and longer withdrawal periods leading to greater decreases in GLT-1 protein. However, the mechanism(s) by which cocaine downregulates GLT-1 protein remains unknown...

Psychostimulant abuse is associated with a variety of impairments in social functioning, including an increased frequency of depression and aggression and deficits in social cognition. Psychostimulants reduce social investigation in rats and mice; however, it is less clear how other forms of social behavior (e.g., prosocial behavior) are affected. Females are also generally more sensitive to the effects of psychostimulants on locomotion and stereotyped behavior, which suggests that females might also display greater disruption of prosocial behavior...

The WHO annually reports an increasing abuse of new psychoactive substances (NPS), which are a heterogeneous group of synthetic drugs and are consumed as substitute for controlled drugs of abuse. In this work, we focused on highly potent derivatives such those of phenethylamine (2C), N-2-methoxybenzyl phenethylamine (NBOMes), lysergic acid diethylamide (LSD), and fentanyl. Severe to fatal intoxications were described due to their high potency. Therefore, they have to be taken at very low doses resulting in low blood concentration in the low ng/mL range, which is a challenge for reliable analytical detection and quantification...

Alternative matrices play a major role in postmortem forensic toxicology, especially if common matrices (like body fluids or hair) are not available. Incorporation of illicit and medicinal drugs into non-mineralized dental biofilm (plaque) seems likely but has not been investigated so far. Analysis of plaque could therefore extend the spectrum of potentially used matrices in postmortem toxicology. For this reason, a rapid, simple and sensitive method for the extraction, determination and quantification of ten drugs of abuse from plaque using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed and fully validated...

Matrix effects are probably the Achilles heel of most quantitative liquid chromatography mass spectrometry (LC-MS) methods based on electrospray ionization. This work reports the evaluation of matrix effects in challenging matrices such as food extracts, human urine or wastewater at different dilution factors using nanoflow liquid chromatography-high resolution mass spectrometry (LC-MS). For this purpose, a suite of representative low-molecular weight compounds such as pesticides, drugs of abuse, sport drugs or environmental contaminants were selected...
