Funding Amount
$1,468,026.00
Summary
The proposed project is a system change within partner emergency departments, providing them the information and tools to act on both risky alcohol consumption in individual patients and the sources of alcohol in the community which cause the harm they experience. Most importantly, the proposed public health interventions act as a tool for emergency departments to regularly raise awareness with the public and policymakers regarding the impact of alcohol on patients, clinicians and hospitals.

Summary
Heroin addiction is a major health and societal problem in Australia. It is consistently associated with an adverse impact upon individual users, their families, and communities. It is a chronically relapsing condition for which few, if any effective prevention and treatment strategies exist. Moreover, why an individual initiates and maintains heroin taking remains unclear. Stress and negative emotions have a strong impact on heroin use. Stress may drive some individuals to start using heroin, s ....Heroin addiction is a major health and societal problem in Australia. It is consistently associated with an adverse impact upon individual users, their families, and communities. It is a chronically relapsing condition for which few, if any effective prevention and treatment strategies exist. Moreover, why an individual initiates and maintains heroin taking remains unclear. Stress and negative emotions have a strong impact on heroin use. Stress may drive some individuals to start using heroin, stress increases the pleasurable effects of heroin and stress increases the aversive effects of heroin withdrawal. These effects will encourage addiction and discourage addicts from seeking treatment. Stress can also cause an otherwise drug-free individual to relapse to heroin addiction despite having been drug-free for some time. In this project we will study why stress has such a large impact on heroin addicts and heroin addiction. We will test the hypothesis that heroin use actually produces profound alterations in the neural network in the brain which controls responses to stress. This project uses a simple animal model of heroin addiction whereby rats are injected with morphine to study the regulation of several genes which are important in responding to stress. We will also study how this exposure and changes in gene expression alter neurobiological, cardiovascular, and behavioural responses to stress. This project will identify parts of the brain that are altered during heroin addiction, and will also identify why heroin addicts are more vulnerable to stress than the general population. Therefore, this project will help us to identify targets for therapeutic intervention (both psychological and pharmacological) and possibly disrupt the addictive cycle.Read moreRead less
The Role Of Anhedonia In Recovery From Opiate Addiction

Funding Amount
$541,022.00
Summary
There is growing evidence that changes occur within the addicted brain reducing a drug user's ability to experience everyday pleasures. In this study, we will examine how a drug user's ability to experience pleasure relates to relapse and recovery. We will conduct a series of tests on a large sample of recently abstinent heroin addicts and follow them for 12 months. This project will provide unique insights that will be of direct relevance to clinical treatment.

An Australian Aboriginal tribe have been known to use B. acutangula aqueous bark extracts for its analgesic properties. Griffith University researchers have confirmed this biological activity in the crude aqueous bark extract. A large scale extraction and isolation process will obtain the novel compounds in sufficient quantities that will allow for their pharmacological evaluation as potential analgesic drugs.Read moreRead less
Characterising Neurobiological Abnormalities In Cannabis Use Disorders

Funding Amount
$731,571.00
Summary
Severe Cannabis Use Disorders cause significant harms to quality of life and outcomes including mental health, cognition, motivation and general well being. We will characterise, for the first time, the neuroadaptations associated with cannabis dependence relative to regular use via advanced imaging techniques and examine links between neural alterations and quality of life. This study will help to identify new treatment targets and develop a new neural model of cannabis addiction.
Refining And Testing A Promising New Treatment For Chronic Pain.

National Health and Medical Research Council
Funding Amount
$743,947.00
Summary
Chronic pain costs Australia about 35 billion dollars a year. Recent scientific discoveries show that treatment aimed at correcting problems in how the brain processes sensory input can reduce pain and disability. This project will clarify some key aspects of these problems and use that information to make final adjustments to an already very promising treatment. We will then test the treatment in a definitive and comprehensive clinical trial.
Does Obesity Have The Characteristics Of Addiction?

Funding Amount
$430,832.00
Summary
The number of overweight or obese people in Australia has increased dramatically in recent years, increasing disease risk. The brain responds to palatable food in ways similar to the response to drugs of addiction, and this may explain why people find it hard to resist palatable food. Our work will explore whether obesity in rats has the characteristics of addiction by examining bingeing, craving, withdrawal and brain circuits in animals chronically exposed to palatable food.
Reduction Of Chronic Post-surgical Pain With Ketamine - ROCKet Study

Funding Amount
$4,823,395.00
Summary
Chronic post-surgical pain (CPSP) is a common complication of major surgery, and a significant burden on quality of life and ongoing health costs. Ketamine is a drug used by anaesthetists to treat severe acute surgical pain. Various small studies suggest that it may be unique in its ability to reduce the risk of CPSP. We propose a large trial of ketamine during & after anaesthesia for major surgery to test this. Demonstration of effectiveness would promote widespread change in clinical practice.
Efficacy Of A 3-month Aerobic Exercise Regime For Restoring 'brain Health' In Heavy Cannabis Users

Funding Amount
$1,209,221.00
Summary
Over a ten-year period, we, and others have documented the brain and psychological harms associated with regular cannabis use. We have now shown that these harms are not permanent, but can be restored. However, the recovery process takes a long time. This study will build on our extensive work to date and, for the first time, investigate whether a specific form of exercise will cause accelerated and beneficial changes in i) the brain and ii) the daily lives of heavy cannabis users.

By the age of 16 around half of all adolescents have suffered back pain and one third have suffered neck pain. For many adolescents this pain is disabling and over a third of sufferers miss school, miss recreation and seek medical help. The current understanding of back and neck pain in adolescence is quite limited - restricting the effectiveness of initiatives to prevent adolescents having to suffer spinal pain and of treatment of those adolescents unlucky enough to have an episode. Better understanding and interventions for adolescent spinal pain will also have longer term implications by reducing adult spinal pain. Four out of 5 adults will experience spinal pain. In the USA treating adult back pain is the 4th largest health care cost. Many adults with chronic back pain had their first episode during adolescence. A better understanding of spinal pain in adolescence may help prevent it developing into a lifelong disability. We will collect information from 2,000 adolescents on their experience of back and neck pain and on potential physical, lifestyle and psychosocial risk factors. We believe factors such as their posture, muscle capacity, TV and computer use, mental health and social situation all combine to influence whether a person develops back or neck pain. The project is unique as it will not only collect a broad range of information during adolescence, but will also make use of a large database of health, developmental and psychosocial information already collected from these children since birth. With a better understanding of the development of spinal pain we will be able to develop guidelines to help prevent these problems. We will also be able to develop better treatment plans for sub-groups of adolescents with a particular combination of risk factors. Together these initiatives will assist in understanding and breaking the pathway to chronic spinal pain.Read moreRead less
