OBJECTIVE: To better identify individuals on chronic opioid therapy (COT) at high risk for aberrant-drug related behavior (ADRB). We examine whether patients with low level alcohol and drug use have similar characteristics to those with alcohol and drug disorders. We then examined the relationship of alcohol and drug use to ADRBs among COT patients. METHODS: The sample was 972 randomly selected COT patients (age 21-80 years old) from a large health system in Northern California, USA, and interviewed in 2009...

Polyvinyl alcohol (PVA) hydrogels with tissue-like viscoelasticity, excellent biocompatibility and high hydrophilicity have been considered as promising cartilage replacement materials. However, lack of sufficient mechanical properties is a critical barrier to their usage as load-bearing cartilage substitutes. Herein, we report hydroxylated boron nitride nanosheets (OH-BNNS)/PVA interpenetrating hydrogels by cyclically freezing/thawing the aqueous mixture of PVA and highly hydrophilic OH-BNNS (up to 0.6 mg/mL, two times the highest reported so far)...

Increased consumption of high-caloric carbohydrates contributes substantially to endemic non-alcoholic fatty liver disease in humans, covering a histological spectrum from fatty liver to steatohepatitis. Hypercaloric intake and lipogenetic effects of fructose and endotoxin-driven activation of liver macrophages are suggested to be essential to disease progression. In the present study, we show that a low dose of an anti-CD163-IgG-dexamethasone conjugate targeting the hemoglobin scavenger receptor CD163 in Kupffer cells and other M2-type macrophages has a profound effect on liver inflammatory changes in rats on a high-fructose diet...

Nalmefene, a long-acting µ-opioid antagonist approved to treat alcohol use disorder, is occasionally mistakenly prescribed to opiate-dependent or opioid-treated patients. We review recent literature on drug-drug interactions between nalmefene and opioids that lead to precipitated opioid withdrawal, and focus on its management and planning for care at discharge. Areas covered: This article provides a brief and comprehensive review of management of precipitated opioid withdrawal syndrome when nalmefene is associated with an opioid, whether misused or legally prescribed...

Fifty percent of adolescents have tried an illicit drug and 70% have tried alcohol by the end of high school, with even higher rates among multiracial youth. Ethnic identity is a protective factor against substance use for minority groups. However, little is known about the mechanisms that facilitate its protective effects, and even less is known about this relationship for multiracial youth. The purpose of the present study was to examine the protective effect of ethnic identity on substance use and to determine whether this relationship operated indirectly through self-esteem, a strong predictor of substance use for among adolescent populations...

BACKGROUND: Individuals who use illicit drugs are at heightened risk for HIV and/or Hepatitis C Virus (HCV). Despite the medical consequences of drinking for drug-using individuals with these infections, many do drink. In other studies, how individuals perceive their health relates to their engagement in risk behaviors such as drinking. However, among drug-using individuals with HIV and HCV, whether perceived health relates to drinking is unknown. OBJECTIVE: We examine the association between perceived health and drinking among drug-using individuals with HIV and/or HCV...

Daicia C Allen, Matthew M Ford, Kathleen A Grant
The progress on understanding the pharmacological basis of ethanol's discriminative stimulus effects has been substantial, but appears to have plateaued in the past decade. Further, the cross-species translational efforts are clear in laboratory animals, but have been minimal in human subject studies. Research findings clearly demonstrate that ethanol produces a compound stimulus with primary activity through GABA and glutamate receptor systems, particularly ionotropic receptors, with additional contribution from serotonergic mechanisms...

REVIEW
David M Lovinger, Veronica A Alvarez
Brain circuits that include the cortex and basal ganglia make up the bulk of the forebrain, and influence behaviors related to almost all aspects of affective, cognitive and sensorimotor functions. The learning of new actions as well as association of existing action repertoires with environmental events are key functions of this circuitry. Unfortunately, the cortico-basal ganglia circuitry is also the target for all drugs of abuse, including alcohol. This makes the circuitry susceptible to the actions of chronic alcohol exposure that impairs circuit function in ways that contribute to cognitive dysfunction and drug use disorders...

A multilayer mat for dispensing colistin sulfate through a body surface was prepared by electrospinning. The fabricated system comprised various polyvinyl alcohol fibrous layers prepared with or without the active ingredient. One of the electrospun layers contained water-soluble colistin sulfate and the other was prepared from the same polymer type and composition without the active drug and was finally heat-treated. The heat treatment modified the supramolecular structure and conferred the polymer nanofibre with the rate-controlling function...

Homeless young adults ages 18-25 exhibit high rates of alcohol and other drug (AOD) use, and sexual risk behaviors such as unprotected sex. Yet few programs exist for this population that are both effective and can be easily incorporated into settings serving this population. This pilot cluster cross-over randomized controlled trial evaluates AWARE, a voluntary four session group-based motivational interviewing (MI) intervention to reduce AOD use and sexual risk behavior. We evaluated AWARE with 200 homeless young adults using drop-in center services in Los Angeles County (mean age=21...

OBJECTIVE: Multisystemic therapy (MST) is perhaps the best validated treatment for youth who engage in serious and chronic antisocial behavior (Henggeler, Schoenwald, Borduin, Rowland, & Cunningham, 2009). Despite evidence suggesting that high treatment adherence is needed to achieve optimal MST outcomes, this research is limited because past studies have relied on adherence reports derived solely from treatment participants (i.e., caregivers, youth, and therapists). To address this gap in the literature, the present study assessed the reliability and predictive validity of an observational protocol for rating adherence to MST...

BACKGROUND: South Australia (SA) has resettled 151,134 refugees in the last ten years (Department of Immigration and Border Protection, Settlement reporting facility, 2014). Northern metropolitan Adelaide, an area which experiences significant social disadvantage, has received a significant number of (predominantly young) refugees. Research indicates that refugee youth are at elevated risk of mental health (MH) and alcohol and other drug (AOD) problems. These factors, along with the low socio-economic status of northern Adelaide, the number of refugee youth residing there, and the added complexity of treating comorbid MH and AOD problems (comorbidity) prompted this research...

New interferon (IFN)-free therapies are not currently available for all patients with chronic hepatitis C due to higher costs; in Italy, patients with genotype 2 (GT2) or GT3 without severe fibrosis can choose between wait or treatment with pegylated (PEG)-IFN and ribavirin. This study wants to examine the real rate of patients that accept or refused this therapy and the reasons related to decision. This prospective, observational analysis was performed at our centre between January 2014 and June 2015. Epidemiological, social and clinical data were collected in medical records; reasons for treatment acceptance/refusal were recorded through a questionnaire...

Aims: Zonisamide is a new anti-epileptic drug whose mechanism of action is associated with neurotransmission systems also involved in the pathogenesis of addiction. Recently, the role of memory processes and the hippocampus (Hp) is underlined in dependence. In our previous study, we determined that zonisamide decreases changes in hippocampal bioelectric activity induced by a single dose of ethanol. Methods: This study uses a pharmaco-EEG method to examine the impact of zonisamide on the development and course of alcohol dependence in rabbits...

Many countries now have national mental health policies and guidelines to decrease or eliminate the use of seclusion and restraint yet the use of Pro Re Nata (PRN) medications has received less practice evaluation. This research aimed to identify mental health nurses' attitudes towards the use of PRN medications with mental health consumers. Participants were working in forensic mental health and non-forensic acute mental health settings. The "Attitudes towards PRN medication use survey" was used and data were collected online...
