PURPOSE: The aim of this study was to investigate deaths among individuals with epilepsy recorded on the National Drug-Related Deaths Index (NDRDI). METHOD: A descriptive analysis of individuals with a known history of epilepsy in the NDRDI from 2004 to 2013 was undertaken. RESULTS: Between 2004 and 2013, 225 (2%) of the recorded cases had a documented history of epilepsy, 82 (36%) of whom had epilepsy recorded as the cause of death. Of these 82 deaths, the majority were male (60-73%) and half (median age) were aged 47 years or younger...

Transcriptome profiling enables discovery of gene networks that are altered in alcoholic brains. This technique has revealed involvement of the brain's neuroimmune system in regulating alcohol abuse and dependence, and has provided potential therapeutic targets. In this review, we discuss Toll-like-receptor pathways, hypothesized to be key players in many stages of the alcohol addiction cycle. The growing appreciation of the neuroimmune system's involvement in alcoholism has also led to consideration of crucial roles for glial cells, including astrocytes and microglia, in the brain's response to alcohol abuse...

AIMS: The PDE4 inhibitor roflumilast is a clinically approved anti-inflammatory drug used for the treatment of chronic obstructive pulmonary disease. In addition, roflumilast was found to reduce body weight and improve glucose metabolism by a yet unknown mechanism. MATERIALS AND METHODS: Metabolic effects of roflumilast were investigated in C57BL/6J mice on high fat western-type diet treated with or without roflumilast for a period of 12 weeks. RESULTS: Roflumilast led to a marked reduction of body weight gain, which became apparent in the second week following treatment initiation and was attributable to a pronounced increase of energy expenditure...

There is evidence that poor sleep mitigates recovery from substance dependence and increases risk of relapse. However, to date research literature is located within biomedical, clinical and psychological paradigms. To complement the extant work, this article offers a sociological exploration of sleep in the context of recovery from dependence on alcohol and/or other drugs. Drawing on qualitative data generated through interviews with 28 men and women living in residential rehabilitation settings in England, we provide a detailed exploration of sleep practices focusing on how these are enacted throughout the night...

BACKGROUND: Medical boards and other practitioner boards aim to protect the public from unsafe practice. Previous research has examined disciplinary actions against doctors, but other professions (e.g., nurses and midwives, dentists, psychologists, pharmacists) remain understudied. We sought to describe the outcomes of notifications of concern regarding the health, performance, and conduct of health practitioners from ten professions in Australia and to identify factors associated with the imposition of restrictive actions...

BACKGROUND: The treatment of methamphetamine dependence is a continuing global health problem. Agonist type pharmacotherapies have been used successfully to treat opioid and nicotine dependence and are being studied for the treatment of methamphetamine dependence. One potential candidate is lisdexamfetamine, a pro-drug for dexamphetamine, which has a longer lasting therapeutic action with a lowered abuse potential. The purpose of this study is to determine the safety of lisdexamfetamine in this population at doses higher than those currently approved for attention deficit hyperactivity disorder or binge eating disorder...

BACKGROUND: Previous studies have shown that total cholesterol (TC) levels are associated with stroke outcomes, but sex differences in the association between TC levels, especially a low TC level, and ischemic stroke outcomes are unknown. We aimed to assess the sex differences in stroke outcomes among patients with atherothrombotic infarctions and low TC levels in China. METHODS: This study recruited patients with atherothrombotic infarctions from Tianjin, China, between May 2005 and September 2014...

OBJECTIVES: International suicide prevention strategies recommend providing support to families bereaved by suicide. The study objectives were to measure the proportion of cases in which psychiatric professionals contact next of kin after a patient's suicide and to investigate whether specific, potentially stigmatizing patient characteristics influence whether the family is contacted. METHODS: Annual survey data from England and Wales (2003-2012) were used to identify 11,572 suicide cases among psychiatric patients...

With the evolving sensitivity of positron emission tomography (PET) and the emergence of novel radiotracers, greater insight has been gained into the dopaminergic system as it relates to substance use. In this review, we summarize PET investigations from the last ten years that explore the dopaminergic system in tobacco, alcohol, stimulant, opiates, and cannabis addiction. In light of the prevalence of substance co-use, this review will also explore the effect of tobacco and other substance abuse co-morbidity on the dopaminergic system across study samples in the reviewed literature...

Substance use and abuse, which includes alcohol use, alcohol dependence, drug use, and drug dependence, inflicts a substantial toll on Americans. Although studies have demonstrated the protective effect of social support, such as religious participation and via marriage, understanding their influence on racial and ethnic minorities is limited. Thus, the aim of this study is to assess the impact of social support on substance use and abuse in racial and ethnic minorities. The Collaborative Psychiatric Epidemiology Surveys, sponsored by the National Institute of Mental Health, a repository of race, ethnicity, and mental health data, was leveraged to develop four models using multivariate analysis, specifically logistic regression to estimate the probability of meeting the criteria for substance use and abuse...

Urease is a nickel-dependent amidohydrolase that catalyses the decomposition of urea into carbamate and ammonia, a reaction that constitutes an important source of nitrogen for bacteria, fungi and plants. It is recognized as a potential antimicrobial target with an impact on medicine, agriculture, and the environment. The list of possible urease inhibitors is continuously increasing, with a special interest in those that interact with and block the flexible active site flap. We show that disulfiram inhibits urease in Citrullus vulgaris (CVU), following a non-competitive mechanism, and may be one of this kind of inhibitors...

Triple-negative breast cancers (TNBC) often exhibit an aggressive phenotype. Disulfiram (DSF) is an approved drug for the treatment of alcohol dependence, but has also been shown to kill TNBC cells in a copper (Cu)-dependent manner. Exactly how this occurs has not been clearly elucidated. We sought to investigate the mechanisms responsible for DSF/Cu-dependent induction of apoptosis and suppression of lung colonization by TNBC cells. DSF/Cu induced anoikis and significantly suppressed cell migration and invasion with negative effects on focal adhesions, coinciding with vimentin breakdown and calpain activation in TNBC cells...

BACKGROUND AND AIMS: Relatively few cannabis dependent individuals seek treatment and little is known about the determinants of treatment seeking. Social Cognitive Theory (SCT) provides a useful framework for examining human behaviour and motivation which may be helpful in explaining treatment seeking. This study examined the differences in cannabis outcome expectancies and cannabis refusal self-efficacy between treatment seekers and non-treatment seekers with cannabis dependence. DESIGN: Non-treatment seekers were referred to an illicit drug diversion program...

Most of the research on public perceptions of people with addictive disorders has focused on alcohol and illicit drugs, rather than addiction to behavioral activities. To expand the range of addictive behaviors and types of perceptions studied, we designed the present study to assess the lay public's definitions of and willingness to affiliate with people described as addicted to 1 of 2 specific behaviors (i.e., pornography or gambling) or 1 of 3 specific substances (i.e., alcohol, marijuana, or heroin). A nationwide convenience sample (N = 612) of American adults completed online questionnaires during the summer of 2015...

Amorphous solid dispersions (SDs) are a promising approach to improve the dissolution rate of and oral bioavailability of poorly water-soluble drugs. In some cases multi-phase, instead of single-phase, SD systems with amorphous drug are obtained. While it is widely assumed that one-phase amorphous systems are desirable, two-phase systems may still potentially exhibit enhanced stability and dissolution advantages over undispersed systems. The objective of the present study was to understand the solid-state properties of two-phase SDs with amorphous drug and their relation to physical stability...

BACKGROUND AND AIMS: Screening, brief intervention and 'referral to treatment' programs have been widely promoted as US federal policy. Little is known about the efficacy of the RT component (referral to treatment) of brief intervention for motivating patients with unhealthy drug use identified by screening to use addiction treatment. This study aimed to compare receipt of addiction treatment following two types of brief intervention for drug use vs a no-intervention control group among primary care patients screening positive for drug use...

BACKGROUND: Concurrent alcohol use among cocaine abusers is common but the behavioral variables that promote co-abuse are not well understood. The present study examined the effects of intragastric (i.g.) ethanol (EtOH) administration in monkeys responding under a schedule of cocaine reinforcement in which extensive drug seeking was maintained by conditioned stimuli. METHODS: Four adult male cynomolgus monkeys (Macaca fascicularis) were trained to respond under a second-order fixed-interval (FI) 600s (fixed-ratio (FR) 30:S) schedule of cocaine (0...

BACKGROUND: Drug-related outcomes expectancies and refusal self-efficacy are core components of Social Cognitive Theory. Both predict treatment outcome in alcohol use disorders. Few studies have reported expectancies and refusal self-efficacy in cannabis dependence. None have examined both, although both constructs are key targets in Cognitive-Behavioural Therapy (CBT). This study tests the predictive role of expectancies and refusal self-efficacy in treatment outcome for cannabis dependence...

BACKGROUND: Problem drinking that predates enlistment into military service may contribute to the overall burden of alcohol misuse in the Armed Forces; however, evidence bearing on this issue is limited. This study examines prevalence and correlates of alcohol misuse among new U.S. Army soldiers. METHODS: Cross-sectional survey data were collected from soldiers reporting for basic combat training. The survey retrospectively assessed lifetime alcohol consumption and substance abuse/dependence, enabling estimation of the prevalence of lifetime binge drinking and heavy drinking in a sample of 30,583 soldiers and of probable alcohol use disorder (AUD) among 26,754 soldiers with no/minimal lifetime use of other drugs...
