AIMS/HYPOTHESIS: The aim of this study was to identify risk factors associated with confirmed fatal hyperglycaemia, which could predispose potentially preventable deaths in individuals on glucose lowering drugs. METHODS: A retrospective register-based case-control study conducted on a nationwide cohort with individuals who died due to hyperglycaemia as determined by forensic postmortem examination, in Sweden August 2006 to December 2012. Vitreous glucose was used to diagnose hyperglycaemia postmortem...

BACKGROUND AND AIMS: The ageing United States (US) population is providing an unprecedented population of older adults who use recreational drugs. We aimed to estimate the trends in the prevalence of past-year use of cannabis, describe the patterns and attitudes, and determine correlates of cannabis use by adults age 50 and older. DESIGN: Secondary analysis of the National Survey on Drug Use and Health survey from 2006 to 2013, a cross-sectional survey given to a nationally representative probability sample of populations living in US households...

The abuse of drugs is now an epidemic globally whose control has been mainly through rehabilitation. The demand for drug abuse rehabilitation has not been matched with the available capacity resulting in limited placement of addicts into rehabilitation. In this paper, we model limited rehabilitation through the Hill function incorporated into a system of nonlinear ordinary differential equations. Not every member of the community is equally likely to embark on drug use, risk structure is included to help differentiate those more likely (high risk) to abuse drugs and those less likely (low risk) to abuse drugs...

BACKGROUND AND RATIONALE: Steven R. Goldberg was a pioneering behavioral pharmacologist whose intravenous drug self-administration studies advanced the understanding of conditioned stimuli and schedules of reinforcement as determinants of pattern and persistence of drug-seeking behavior, and in particular, the importance of nicotine in tobacco use. His passing in 2014 led to invitations to contribute articles to psychopharmacology dedicated to his work. OBJECTIVES: The objectives of this review are to summarize and put into historical perspective Goldberg's contributions to elucidate the reinforcing effects of nicotine and to summarize the implications of his research for medication development, tobacco regulation, and potential tobacco control policy options...

PURPOSE: The clinical decision to replant an amputated digit is driven primarily by surgical indication. However, the extent to which patient comorbidity should play into this decision is less well defined. This study was designed to determine the effect of patient comorbidities on the success, risk, and cost of digital replantation. METHODS: All amputation injuries and digital replantation procedures captured by the National Inpatient Sample during 2001 to 2012 were identified...

Overdose deaths involving opioid pain medications are epidemic in the United States, in part because of high opioid prescribing rates and associated abuse of these drugs (1). In 2014, nearly 2 million U.S. residents either abused or were dependent on prescription opioids (2). In Massachusetts, unintentional opioid-related overdose deaths, including deaths involving heroin, increased 45% from 2012 to 2013.* In 2014, the rate of these deaths reached 20.0 per 100,000, nearly 2.5 times higher than the U.S. rate overall (3,4)...

OBJECTIVE: A recent HIV outbreak in a rural network of persons who inject drugs (PWID) underscored the intersection of the expanding epidemics of opioid abuse, unsterile injection drug use (IDU), and associated increases in hepatitis C virus (HCV) infections. We sought to identify US communities potentially vulnerable to rapid spread of HIV, if introduced, and new or continuing high rates of HCV infections among PWID. DESIGN: We conducted a multistep analysis to identify indicator variables highly associated with IDU...

OBJECTIVES: Opioid overdose mortality has tripled in the USA since 2000 and opioids are responsible for more than half of all drug overdose deaths, which reached an all-time high in 2014. Opioid overdoses resulting in death, however, represent only a small fraction of all opioid overdose events and efforts to improve surveillance of this public health problem should include tracking nonfatal overdose events. International Classification of Disease (ICD) diagnosis codes, increasingly used for the surveillance of nonfatal drug overdose events, have not been rigorously assessed for validity in capturing overdose events...

D3 receptors represent a major focus of current drug design and development of therapeutics for dopamine-related pathological states. Their close homology with the D2 receptor subtype makes the development of D3 selective antagonists a challenging task. In this review, we explore the relevance and therapeutic utility of D3 antagonists or partial agonists endowed with multireceptor affinity profile in the field of central nervous system disorders such as schizophrenia and drug abuse. In fact, the peculiar distribution and low brain abundance of D3 receptors make them a valuable target for the development of drugs devoid of motor side effects classically elicited by D2 antagonists...

BACKGROUND: The impact of pain in sexuality, couple relationships and the quality of life is very well known. OBJECTIVES: The relationship between substance abuse and the presence of sexual pain disorder is assessed, together with anxiety and sexual attitudes . METHOD: Two samples were selected. One sample for women with a history of substance abuse (n = 129), and another one of women nonconsumers (n = 129). The Golombok Rust Inventory of Sexual Satisfaction (GRISS), the Sexual Opinion Survey (SOS) and the State Trait Anxiety Inventory (STAI) questionnaires were used...

We report a case of isolated native tricuspid valve infective endocarditis caused by Coagulase Negative Staphylococcus in a non-IV drug abuser without structural heart disease. Early diagnosis and prompt initiation of appropriate treatment saved the patient without surgical intervention. The recent trend of Coagulase Negative Staphylococci (CoNS) causing native valve endocarditis (NVE) is reviewed with literature.

Carisoprodol is a widely prescribed muscle relaxant and is also a drug known to be a subject to abuse. Despite the fact that carisoprodol has been available for prescription since 1959, a number of gaps in our knowledge of the toxicokinetics of this common drug exist. For example, the volume of distribution (Vd) for carisoprodol in humans has not been reported. A two-compartment pharmacokinetic model describing carisoprodol metabolism and that of the primary metabolite, meprobamate, was developed to better understand the pharmacokinetics of this drug...

Some medical scientists argue that only data from randomized controlled trials (RCTs) are trustworthy. They claim data from natural experiments and administrative data sets are always spurious and cannot be used to evaluate health policies and other population-wide phenomena in the real world. While many acknowledge biases caused by poor study designs, in this article we argue that several valid designs using administrative data can produce strong findings, particularly the interrupted time series (ITS) design...

Sensitivity to the rewarding properties of appetitive substances has long been implicated in excessive consumption of palatable foods and drugs of abuse. Previous research focusing on individual differences in reward responsiveness has found heightened trait reward sensitivity to be associated with binge-eating, hazardous drinking, and illicit substance use. Food addiction has been proposed as an extreme form of compulsive-overeating and has been associated with genetic markers of heightened reward responsiveness...

BACKGROUND: Forensic physicians are responsible for first-line medical care of detainees (individuals held in custody) in the police station. The Dutch police law contains a 'duty of care', which gives the police responsibility for the apparent mentally ill and/or confused people they encounter during their work. The police can ask a forensic physician to do a primary psychiatric assessment of any apparent mentally ill detainee. The forensic physician determines if the apparent mentally ill behavior of the detainee is due to a somatic illness, or has a psychiatric cause for which the detainee needs admission to a psychiatric hospital...

Families of substance abusers may develop maladaptive strategies, such as codependency, to address drug-related problems. It is important for families to receive specialist treatment in order to contribute to the recovery process. The Tele-intervention Model and Monitoring of Families of Drug Users (TMMFDU), based on motivational interviewing and stages of change, aims to encourage the family to change the codependents' behaviors. A randomized clinical trial was carried out to verify the change in codependent behavior after intervention with 6 months of follow-up...

Methamphetamine, one of the most frequently used illicit drugs worldwide, can induce psychosis in a large fraction of abusers and it is becoming a major problem for the health care institutions. There is some evidence that genetic and epigenetic factors may play roles in methamphetamine psychosis. In this study, we examined methamphetamine-induced epigenetic and expression changes of several key genes involved in psychosis. RNA and DNA extracted from the saliva samples of patients with methamphetamine dependency with and without psychosis as well as control subjects (each group 25) were analyzed for expression and promoter DNA methylation status of DRD1, DRD2, DRD3, DRD4, MB-COMT, GAD1, and AKT1 using qRT-PCR and q-MSP, respectively...

The present review briefly explores the neurotoxic properties of methcathinone, mephedrone, methylone, and methylenedioxypyrovalerone (MDPV), four synthetic cathinones most commonly found in "bath salts." Cathinones are β-keto analogs of the commonly abused amphetamines and display pharmacological effects resembling cocaine and amphetamines, but despite their commonalities in chemical structures, synthetic cathinones possess distinct neuropharmacological profiles and produce unique effects. Among the similarities of synthetic cathinones with their non-keto analogs are their targeting of monoamine systems, the release of neurotransmitters, and their stimulant properties...

Addiction to cocaine and other psychostimulants represents a major public health crisis. The development and persistence of addictive behaviors comes from a complex interaction of genes and environment - the precise mechanisms of which remain elusive. In recent years a surge of evidence has suggested that the gut microbiome can have tremendous impact on behavioral via the microbiota-gut-brain axis. In this study we characterized the influence of the gut microbiota on cocaine-mediated behaviors. Groups of mice were treated with a prolonged course of non-absorbable antibiotics via the drinking water, which resulted in a substantial reduction of gut bacteria...
