Abortion is a very sensitive issue with relevance to public health; however few clinical or population-based studies have examined induced abortion among drug users. The study aims to evaluate the prevalence of induced abortion and sex-related conditions in an inpatient drug user sample. A cross-sectional design study was conducted in an inpatient addiction treatment unit in São Paulo, Brazil, with a sample of 616 patients, aged 18-75. Sociodemographic data, sexual behavior, and dependence severity were evaluated in relation to induced abortion...

Free will has been the object of debate in the context of addiction given that addiction could compromise an individual's ability to choose freely between alternative courses of action. Proponents of the brain-disease model of addiction have argued that a neuroscience perspective on addiction reduces the attribution of free will because it relocates the cause of the disorder to the brain rather than to the person, thereby diminishing the blame attributed to the person with an addiction. Others have worried that such displacement of free will attribution would make the person with a drug addiction less responsible...

Agmatine (1-amino-4-guanidinobutane), a precursor for polyamine biosynthesis, has been identified as an important neuromodulator with anticonvulsant, antineurotoxic and antidepressant actions in the brain. In this context it has emerged as an important mediator of addiction/satiety pathways associated with alcohol misuse. Consequently, the regulation of the activity of key enzymes in agmatine metabolism is an attractive strategy to combat alcoholism and related addiction disorders. Agmatine results from the decarboxylation of L-arginine in a reaction catalyzed by arginine decarboxylase (ADC), and can be converted to either guanidine butyraldehyde by diamine oxidase (DAO) or putrescine and urea by the enzyme agmatinase (AGM) or the more recently identified AGM-like protein (ALP)...

Relative to bred low-responder (bLR) rats, bred high-responder (bHR) rats have an exaggerated locomotor response to a novel environment, are more risk-taking, more impulsive, and more likely to exhibit compulsive drug-seeking behaviors. These phenotypic differences in addiction-related behaviors and temperament have previously been associated with differences in neurotransmitter signaling, including the mesolimbic dopamine system. In the current study, we applied advanced in vivo microdialysis sampling in the nucleus accumbens of bHRs/bLRs to assess differences in basal and stimulated neurochemical efflux more broadly...

BACKGROUND: Treatment success in obesity remains low, and recently food addiction has been delineated as an underlying etiologic factor with therapeutic relevance. Specifically, current treatment focuses on reduced food intake and increase of physical activity, whereas interventions for addiction encompass behavioral therapy, abstinence, and environmental interventions such as taxation, restrictions on advertising, and regulation of school menus. CONTENT: Here, we reviewed the pertinent literature on food addiction with a specific focus on the role of high-glycemic-index carbohydrates in triggering addictive symptoms...

Epidemiological studies report strong association between mood disorders and tobacco addiction. This high comorbidity requires adequate treatment but the underlying mechanisms are unknown. We demonstrate that nicotine exposure, independent of drug withdrawal effects, increases stress sensitivity, a major risk factor in mood disorders. Nicotine and stress concur to induce long-lasting cellular adaptations within the dopamine (DA) system. This interplay is underpinned by marked remodeling of nicotinic systems, causing increased ventral tegmental area (VTA) DA neurons' activity and stress-related behaviors, such as social aversion...

BACKGROUND: Brivaracetam is a new antiepileptic drug indicated for adjunctive treatment of focal seizures in adults at a dose of 50-200mg/day taken in two equal doses. The objective of this study was to evaluate the abuse potential of brivaracetam compared with alprazolam (positive control), placebo, and levetiracetam. METHODS: This was a randomized, double-blind, triple-dummy, crossover study in healthy male and female recreational central nervous system (CNS) depressant users aged 18-55years, who could distinguish between the subjective effects of alprazolam 2mg and placebo...

A diagnostic criterion for drug addiction, persistent drug-craving continues to be the most treatment-resistant aspect of addiction that maintains the chronic, relapsing, nature of this disease. Despite the high prevalence of psychomotor stimulant addiction, there currently exists no FDA-approved medication for craving reduction. In good part, this reflects our lack of understanding of the neurobiological underpinnings of drug-craving. In humans, cue-elicited drug-craving is associated with the hyper-excitability of prefrontal cortical regions...

BACKGROUND: Improving the extent to which evidence-based practices (EBPs)-treatments that have been empirically shown to be efficacious or effective-are integrated within routine practice is a well-documented challenge across numerous areas of health. In 2014, the National Institute on Drug Abuse funded a type 2 effectiveness-implementation hybrid trial titled the substance abuse treatment to HIV Care (SAT2HIV) Project. Aim 1 of the SAT2HIV Project tests the effectiveness of a motivational interviewing-based brief intervention (MIBI) for substance use as an adjunct to usual care within AIDS service organizations (ASOs) as part of its MIBI Experiment...

Supervised injectable opioid assisted treament (siOAT) prescribes injectable opioids to individuals for whom other forms of addiction treatment have been ineffective. In this article, we examine arguments that opioid-dependent people should be assumed incompetent to voluntarily consent to clinical research on siOAT unless proven otherwise. We agree that concerns about competence and voluntary consent deserve careful attention in this context. But we oppose framing the issue solely as a matter of the competence of opioid-dependent people and emphasize that it should be considered in the context of inequities in access to siOAT as a medical treatment...

The prevailing opioid crisis has necessitated the need to understand mechanisms leading to addiction and tolerance, the major contributors to overdose and death and to develop strategies for developing drugs for pain treatment that lack abuse liability and side-effects. Opioids are commonly used for treatment of pain and symptoms of inflammatory bowel disease. The significant effect of opioids in the gut, both acute and chronic, includes persistent constipation and paradoxically may also worsen pain symptoms...

Clinical trials to test the safety and efficacy of analgesics across all pediatric age cohorts are needed to avoid inappropriate extrapolation of adult data to children. However, the selection of acute pain models and trial design attributes to maximize assay sensitivity, by pediatric age cohort, remains problematic. Acute pain models used for drug treatment trials in adults are not directly applicable to the pediatric age cohorts - neonates, infants, toddlers, children, and adolescents. Developmental maturation of metabolic enzymes in infants and children must be taken into consideration when designing trials to test analgesic treatments for acute pain...

BACKGROUND AND AIMS: This narrative review aimed to provide a brief overview of five key research 'classics' produced by the innovative and radical thought leader, Professor Michael Anthony Hamilton Russell (1932-2009), drawing upon his other work wherever feasible. METHODS: Narrative review. From more than 250 publications, we selected papers we considered seminal texts, published in 1971, 1976, 1978, 1979 and 1991. RESULTS: Russell was among the first researchers to explain that smoking was a dependence disorder caused by the drug nicotine decades before this was recognized formally...

INTRODUCTION: The causal direction of the relationship between sleep disturbance and drug cravings is unknown. Based on resource depletion literature, we hypothesized that sleep difficulties lead to cravings. We tested whether sleep quality predicts craving at the within- or between-person level, with perceived willpower as a multilevel mediator. METHODS: We used ecological momentary assessments (EMA) to compare two models of temporal precedence. Participants in addiction treatment (N=122) were sent four surveys each day for three weeks...

Considering the results of a previous study in which 2321 regular heroin addicts who died without having stopped taking the drug since they had started - from various causes but none from cancer, may mean something. Our first thought was: Can't we hypothesize, reinforcing our previous view that heroin is a "barrier" against cancer and as the user gets in the methadone program he/she lacks the "barrier" and therefore is liable to develop cancer? We have already reported that the amount of blood phosphorus in heroin addicted is significantly lower than in healthy ones...

BACKGROUND AND AIMS: Research on Neonatal Abstinence Syndrome has prompted discussion over how to ensure best outcomes for pregnant women who use drugs and for drug-dependent newborns. Before Neonatal Abstinence Syndrome and the 1980s panic of "crack babies," turn-of-the-century American medical journals discussed infants born to drug-using mothers. This paper aimed to determine whether women who used drugs while pregnant in early twentieth-century America were subject to the stigma many face today...

Orexins are hypothalamic neuropeptides playing important roles in many functions including the motivation of addictive behaviors. Blockade of the orexin-1 receptor has been suggested as a potential strategy for the treatment of drug addiction. We have previously reported OX1 receptor antagonists based on the tetrahydroisoquinoline scaffold with excellent OX1 potency and selectivity; however, these compounds had high lipophilicity (clogP > 5) and low to moderate solubility. In an effort to improve their properties, we have designed and synthesized a series of analogues where the 7-position substituents known to favor OX1 potency and selectivity were retained, and groups of different nature were introduced at the 1-position where substitution was generally tolerated as demonstrated in previous studies...
