Summary
Chronic pain is a growing and poorly treated global health burden. There is a great need for novel pain therapeutics. We are discovering novel drug targets in pain pathways in the nervous system and new therapeutic molecules that selectively block information flow in pain nerves. Strong pain relieving drugs like morphine also lose their effectiveness after long periods of use. We are finding mechanisms responsible for this thereby providing a rational basis for development of better opioids and ....Chronic pain is a growing and poorly treated global health burden.

Summary
Harms related to injecting drug use represent the bulk of the burden attributable to illicit drugs in Australia. In this study we will determine rates of long term cessation of injecting drug use, and relapse, and key drivers of these outcomes such as drug treatment or housing provision. Findings will inform policy and practice around injecting drug use in Australia over the coming decade.

Summary
Mental & substance use disorders account for more years of disability than any other disorder. In young adults the top 10 causes of burden of disease are dominated by mental and substance use disorders. I lead an international program of research in the combined areas of mental health & substance abuse, and am recognised as a leading international expert. My research aims to increase our understanding of drug & alcohol and mental disorders, prevent where possible and improve treatment responses.
Assessing Naltrexone Implant Or Methadone Maintenance Treatment On Mental And Physical Health Outcomes In Heroin Users

Summary
The WA hospital data linkage system (DLS) will be used to assess differences in the mental and physical health of dependent heroin users prior to and post naltrexone implant or methadone maintenance treatment (MMT). MMT is the best established pharmacotherapy for the management of heroin dependence but oral naltrexone is gaining some acceptance. Currently funded by NHMRC, we are looking at outcomes with oral naltrexone using DLS data.

MMT is the best established pharmacotherapy for the management of heroin dependence but oral naltrexone is gaining some acceptance. Currently funded by NHMRC, we are looking at outcomes with oral naltrexone using DLS data. Although effective in blocking heroin, management via oral naltrexone has proved problematic, with medicine non compliance and relapse common. Surgical insertion of subcutaneous implants is an alternative method of naltrexone delivery. 441 heroin users have received naltrexone implants (3.4g) under Special Access in WA. Although naltrexone implants have yet to be comprehensively assessed, early results are encouraging. Pilot study data has shown a significant reduction in hospital emergency department (ED) attendance for accidental overdose, and mental health events following implant. The aim of this study is to more rigorously assess outcomes associated with implants compared to heroin dependent persons treated by MMT . The DLS collates general hospital and mental health admissions plus mortality data for individuals. This allows the health of an individual to be monitored over time. An electronic version of hospital ED data has recently become available. The study will validate these records by comparing the electronic data against hospital ED records for the implant group. We will then combine the electronic ED and DLS data. Morbidity and mortality rates for heroin users are significantly greater than those for the general population. If the preliminary findings are replicated, naltrexone implants may offer significant benefits over current pharmacotherapies in reducing general and psychiatric morbidity in dependent heroin users.Read moreRead less
A Double Blind Placebo Randomised Controlled Trial Of Sativex In The Management Of Cannabis Withdrawal

Summary
Cannabis is the most commonly used illicit drug in Australia with an estimated 300,000 individuals with cannabis use disorder in Australia. Treatment presentations for cannabis have more than doubled over the last 10 years, yet there is still no medication to help with withdrawal. This proposal will test pure active ingredients in cannabis in a preparation sprayed in the mouth, to wean individuals from cannabis. This will assist them to complete cannabis withdrawal.
Ethanol abuse, alcoholism and the medical complications of excessive drinking are now major health problems worldwide. The alcohol dependence syndrome is characterised by tolerance and physical dependence ( the presence of a withdrawal syndrome). Ethanol withdrawal, in addition, to being a health hazard in itself, can act as a negative reinforcer to promote continued ethanol consumption.

The alcohol dependence syndrome is characterised by tolerance and physical dependence ( the presence of a withdrawal syndrome). Ethanol withdrawal, in addition, to being a health hazard in itself, can act as a negative reinforcer to promote continued ethanol consumption. Alcohol dependence can be considered to result from adaptive changes produced by the chronic presence of ethanol in the brain. In this research programme we will learn more about the adaptive changes in the NMDA receptors, the major excitatory receptors in the brain. Current psychopharmacologic management of human alcoholism is limited and suboptimal. We will explore the efficacy of drugs to control behaviours and withdrawal-induced brain cell death. Effective treatment of the syndrome is crucial since withdrawal induces changes, which increases the severity of subsequent withdrawal episodes and its associated brain damage. The outcomes of this research will be a better understand of the underlying changes involved in ethanol dependence and better therapies to ameliorate the withdrawal syndrome.Read moreRead less
Implementing Population-specific Psychosocial Interventions To Optimise Treatment, Care And Support Among Men Who Have Sex With Men Who Use Methamphetamine

Summary
Methamphetamine dependence is a key public health priority and men who have sex with men are identified as a priority population. Our partnership will develop interventions which will be linked to the cohort data to permit us to monitor the impact on health outcomes and access to care and support over time. The findings will support the process of creating and evaluating innovations with the ultimate goal of improving access to care and support and reducing dependence and its harmful outcomes.

Summary
Loss of independence is common after stroke, and may lead to reduced quality of life and admission to nursing home care. We will investigate if an increased amount of rehabilitation following stroke leads to improved mobility. Two ways of delivering more intense rehabilitation will be compared with usual care to find out which leads to improved physical mobility, and how they compare economically. This will allow health service providers to optimise services and will benefit people with stroke.
