In this study, we examine the composition of electroencephalographic (EEG) oscillations within a broad frequency band (0.5-30 Hz) for opioid abuse (22 patients), during withdrawal (13 patients), and after 6 months of methadone treatment (6 patients) and in 14 healthy subjects during a resting condition (closed eyes). The exact compositions of EEG oscillations and their temporal behaviour were a...

BACKGROUND Although Indigenous Australians are over-represented among heroin users, there has been no study examining offending, time in custody, and opioid substitution therapy (OST) treatment utilisation among Indigenous opioid-dependent (including heroin) people at the population level, nor comparing these to non-Indigenous opioid-dependent people. The aims of this study were to compare the ...

BACKGROUND Coverage is used as one indicator of needle and syringe program (NSP) effectiveness. At the individual level, coverage is typically defined as an estimate of the proportion of a person who injects drugs' (PWID) injecting episodes that utilise a sterile syringe. In this paper, we explore levels of individual syringe coverage and its changes over time. METHODS Data were extracted fro...

The high prevalence of HIV infection and drug dependence among prisoners, combined with the sharing of injecting drug equipment, make prisons a high-risk environment for the transmission of HIV. Ultimately, this contributes to HIV epidemics in the communities to which prisoners return on their release. We reviewed the effectiveness of interventions to reduce injecting drug use risk behaviours a...

This article summarizes the challenges, opportunities and lessons learned from presentations, discussions and debates addressing major policy and programmatic responses to HIV in six geographical regions: Sub-Saharan Africa, Asia and the Pacific, Eastern Europe and Central Asia, Latin America, Caribbean, and Middle East and North Africa. It draws from AIDS 2008 Leadership and Community Programm...

BACKGROUND Buprenorphine is a partial agonist at the mu-opioid receptor that has been proposed as an alternative to traditional full agonist maintenance therapy for the treatment of opioid addiction. We report on a clinical trial in which the relative safety and efficacy of long-term fixed-dose buprenorphine maintenance was examined in comparison to low- and high-dose methadone maintenance. M...

BACKGROUND This paper is based on research examining stakeholder involvement in substitution treatment policy which was undertaken as part of the EU funded FP7 ALICE-RAP (Addictions and Lifestyles in Contemporary Europe - Reframing Addictions Project). In England, the research coincided with a policy shift towards a recovery orientated drug treatment framework and a heated debate surrounding th...

BACKGROUND People who inject drugs (PWID) use healthcare services, including primary care, at a disproportionately high rate. We investigated key correlates of general practitioner (GP) related service utilisation within a cohort of PWID. METHODS Using baseline data from a cohort of 645 community-recruited PWID based in Melbourne, Victoria, we conducted a secondary analysis of associations be...

Objectives. A recent US federal review and clinical guideline on opioids for chronic pain asserted that the literature contributes no evidence on efficacy because all trials had “inadequate duration.” To explore the evidence, we examined durations of studies on opioid, nonopioid drug, and behavioral therapies for chronic pain. Methods. We retrieved Cochrane reviews of anticonvulsants, antidepre...

Agonist-induced receptor phosphorylation is an initial step in opioid receptor desensitization, a molecular mechanism of opioid tolerance and dependence. Our previous research suggested that agonist-induced d-opioid receptor (DOR) phosphorylation occurs at the receptor carboxyl terminal domain. The current study was carried out to identify the site of DOR phosphorylation during agonist stimulat...
