Summary
Heroin addiction is an established and increasing problem in developed countries and in many developing nations. Although there have been several new treatments for heroin addiction, methadone maintenance remains the most effective way to minimize the harms associated with heroin addiction. The current research proposal seeks to test a new approach to setting of methadone dose, using monitoring of methadone blood levels, effects and side-effects in determining when to increase doses, and when to ....Heroin addiction is an established and increasing problem in developed countries and in many developing nations. Although there have been several new treatments for heroin addiction, methadone maintenance remains the most effective way to minimize the harms associated with heroin addiction. The current research proposal seeks to test a new approach to setting of methadone dose, using monitoring of methadone blood levels, effects and side-effects in determining when to increase doses, and when to switch to alternative therapies. This provides an objective method of planning treatment that focuses on suppressing heroin use. The potential subjects of the study are the 50% of patients who continue to use heroin regularly during treatment. All will undergo assessment involving measurement of blood levels of methadone, testing of effects and side-effects of methadone, and monitoring of safety. Half will be randomly allocated to usual care, and half to therapeutic drug monitoring, with dose adjustments according to the results of testing. At 3 and 6 months all subjects will undergo repeat test sessions. It is hypothesized that those in the experimental group will be using less heroin (confirmed by hair testing). It is expected that the study will also identify a small group of subjects with genetically different opioid receptors, who will require very high doses of methadone to be stabilized. The study will allow a detailed analysis of how best to monitor dose adequacy; the relationship between withdrawal symptoms, methadone blood levels, and heroin use, and will provide the first clear investigation of the relationship between changes in methadone blood concentration and certain potentially dangerous changes in the electrical activity of the heart. The intended outcome of this research project is a model for a higher standard methadone program that is more effective in reducing the problems of heroin use in our community.Read moreRead less
The Alternate Day Fasting Diet In Adolescents With Obesity: A Randomised Controlled Trial

Summary
One in four Australian adolescents is overweight or obese. While short-term weight loss is possible, keeping the weight off long term is difficult. We will test whether the alternate day fasting diet is effective, safe and acceptable to adolescents. We will undertake a trial involving adolescents aged 13-17 years who are affected by obesity: they will be randomised to receive either the alternate day fasting diet, or a standard weight control diet.
Obesity In The Elderly: Impact Of Weight Loss Therapy On Physiology And Function.

Summary
The aim of this study is to assess the safety, tolerability, weight-loss efficacy, change in lean body mass and impact of cognition of three approaches to treat obesity in the elderly. We will compare dietary advice, an energy reduced diet and a very low calorie diet. All three groups will also have an exercise program. This study will be of major assistance in developing management guidelines for obesity in the elderly, which will likely be an emerging public health issue.
