Relapse to nonmedical use of prescription opioids often occurs after exposure to places previously associated with drug use. Here, we describe a rat model of context-induced reinstatement of oxycodone seeking after repeated cycles of drug self-administration and extinction-induced abstinence. We also determined the role of mu, delta, and kappa opioid receptors (MOR, DOR, KOR) in this reinstatement. We trained rats to self-administer oxycodone for 6 h/d in Context A; lever pressing was paired with a discrete cue...

BACKGROUND: Electronic cigarettes (ECIGs) are a class of tobacco products that produce different effects (e.g., nicotine delivery), depending on the device, liquid, and behavioral factors. However, the influence of the two primary ECIG liquid solvents, propylene glycol (PG) and vegetable glycerin (VG), on ECIG acute effects is unknown. METHODS: Thirty ECIG-experienced, ≥12-h nicotine- abstinent participants completed four conditions consisting of two ECIG-use bouts (10 puffs, 30 s interpuff-interval) differing only by liquid PG:VG ratio (2PG:98VG, 20PG:80VG, 55PG:45VG, 100PG)...

BACKGROUND: Smoking induces complications in plastic surgery, in particular wound healing delays. Despite a 4-weeks' abstinence asking before and after surgery, some patients denied or hid their consumption. The aim of this study was to evaluate the effectiveness of a cotininury detection test in terms of improvement in outcomes after an abdominoplasty. MATERIAL AND METHODS: This retrospective cohort study included patients who underwent an abdominoplasty with umbilical transposition and lipoaspiration...

BACKGROUND: The effectiveness of nonconsummatory reinforcers habituate, as their ability to maintain reinforced responding declines over repeated presentations. Preclinical research has shown that nicotine can delay habituation of reinforcer effectiveness, but this effect has not been directly demonstrated in humans. OBJECTIVE: In preliminary translational research, we assessed effects of nicotine from tobacco smoking (vs. a no smoking control) on within-session patterns of responding for a brief visual reinforcer...

BACKGROUND: Deep transcranial magnetic stimulation (DTMS) is a non-invasive method of stimulating widespread cortical areas and, presumably, deeper neural networks. The current study assessed the effects of DTMS in the treatment of substance use disorders (SUD) using a systematic review. METHODS: Electronic literature search (PsycInfo, Medline until April 2017) identified k = 9 studies (k = 4 randomized-controlled trials, RCTs, with inactive sham and k = 5 open-label studies)...

BACKGROUND: Mandating a reduction in the nicotine content of cigarettes to a minimally addictive level could dramatically reduce smoking rates in the US. However, little is known about the effects of reduced nicotine content cigarettes in adolescents. METHODS: Following overnight abstinence, adolescent daily smokers (ages 15-19, n = 50) reported on their craving, withdrawal, and positive and negative affect pre- and post- ad lib smoking of one cigarette containing varying nicotine content (15...

BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) is overrepresented among individuals seeking treatment for substance use disorders. We previously reported that treatment with extended release mixed amphetamine salts (MAS-XR) increased abstinence, compared to placebo, among patients with co-occurring ADHD and cocaine dependence. This secondary analysis investigates the temporal relationship between ADHD improvement and cocaine abstinence in the first six weeks of the trial...

OBJECTIVE: We conducted this study to determine whether alcohol consumption influences radiological progression in early rheumatoid arthritis (RA). METHOD: Patients fulfilling the European League Against Rheumatism/American College of Rheumatology 2010 criteria in the early arthritis cohort ESPOIR (Étude et Suivi des Polyarthrites Indifférenciées Récentes) were included in this study. Alcohol consumption was collected at baseline and at each visit. We classified alcohol consumption into three groups: abstinent (0 g/day), moderate (≤ 20 g/day for women, ≤ 30 g/day for men), and abuse (> 20 g/day for women, > 30 g/day for men)...

Previous preclinical and clinical investigations have focused on the L-type calcium channel (LTCC) as a potential therapeutic target for substance abuse. While some clinical studies have examined the ability of LTCC blockers to alter cocaine's subjective effects, very few LTCC studies have examined cocaine relapse. Here, we examined whether ventral tegmental area (VTA)-specific or systemic administration of the LTCC inhibitor, isradipine, altered cocaine-seeking behavior in a rat model. Male Sprague-Dawley rats first received 10 days of cocaine self-administration training (2 h sessions), where active lever depression resulted in delivery of a ∼0...

BACKGROUND: Alcohol misuse is a major social and public health issue in Australia, with an estimated cost to the community of Aus $30 billion per annum. Until recently, a major barrier in addressing this significant public health issue is the fact that the majority of individuals with alcohol use disorders and alcohol misuse are not receiving treatment. OBJECTIVE: This study aimed to assess whether alcohol consumption changes are associated with participation in Hello Sunday Morning's blog platform, an online forum discussing experiences in abstaining from alcohol...

INTRODUCTION: Three drugs are used as an aid for smoking cessation: nicotine replacement therapy (NRT), varenicline and bupropion. Standard pharmacological strategies have proven their efficacy but may have poor efficacy, especially among "Hard-core smokers" who display low smoking abstinence rates and high relapse rates. OBJECTIVES: Systematic literature review of data on pharmacological strategies for smoking cessation which are different from standard treatments...

The incidence of infant opioid withdrawal has grown rapidly in many countries, including Canada, in the last decade, presenting significant health and early brain development concerns. Increased prenatal exposure to opioids reflects rising prescription opioid use as well as the presence of both illegal opiates and opioid-substitution therapies. Infants are at high risk for experiencing symptoms of abstinence or withdrawal that may require assessment and treatment. This practice point focuses specifically on the effect(s) of opioid withdrawal and current management strategies in the care of infants born to mothers with opioid dependency...

Acute nicotine abstinence in cigarette smokers results in deficits in performance on specific cognitive processes, including working memory and impulsivity which are important in relapse. Cannabidiol (CBD), the non-intoxicating cannabinoid found in cannabis, has shown pro-cognitive effects and preliminary evidence has indicated it can reduce the number of cigarettes smoked in dependent smokers. However, the effects of CBD on cognition have never been tested during acute nicotine withdrawal. The present study therefore aimed to investigate if CBD can improve memory and reduce impulsivity during acute tobacco abstinence...

INTRODUCTION: Adults with alcohol dependence (AD) have exceptionally high smoking rates and poor smoking cessation outcomes. Discovery of factors that predict reduced smoking among AD smokers may help improve treatment. This study examined baseline predictors of smoking quantity among AD smokers in a pharmacotherapy trial for smoking cessation. METHODS: The sample includes male, AD smokers (N = 129) with 1-32 months of alcohol abstinence who participated in a 12-week trial of medication (topiramate vs...

Health care systems are challenged with issues of overdiagnosis and overtreatment. Neonatal abstinence syndrome (NAS) may be overdiagnosed with standardized assessment protocols and may be overtreated with current NICU-based models of care. Clinical approaches to caring for neonates with NAS and their families have not significantly changed for 40 years, and there is growing interest in revisiting long-standing routine practices. I used Bronfenbrenner's social ecological systems framework to organize an exploration of factors that contribute to overdiagnosis and overtreatment in the care of neonates with NAS...

Few studies have evaluated the effectiveness of Zika virus (ZIKV) public health educational campaigns. Following a ZIKV educational campaign in Roatán, Honduras (October 2016), a survey was administered (March-May 2017) to residents ( N = 348) and health-care professionals ([HCPs]; N = 44) to evaluate ZIKV knowledge, attitudes, and preventive practices, with attention to sexual health. Knowledge scores were calculated and mapped using participants' home locations. The knowledge scores between HCPs and residents were significantly different (mean 17 versus 11; P < 0...
