Predicting Obstructive Sleep Apnoea Using 3D Craniofacial Photography

Funding Amount
$424,715.00
Summary
Sleep Apnoea is a common medical condition associated with snoring and collapse of the throat during sleep. Diagnosis of sleep apnoea involves an overnight sleep study in a specialised laboratory, which is expensive and time consuming. It is possible that sleep apnea could be diagnosed from a 3-dimensional photograph of the face. This study will define the relationships between sleep apnea and 3D face photographs in 956 young adults and 1,200 of their parents, and 3,000 sleep clinic patients.
Improving Rapid Decision-Making In The Face Of Uncertainty: A Randomised Trial Of A 1-hour Troponin Protocol In Suspected Acute Coronary Syndromes

Summary
Chest pain patients are a large burden of emergency department demand. Their effective care requires timely risk assessment. High-sensitivity assays for heart muscle damage (troponin) increases the ability to detect patients at low risk for heart attack but treatment rules based on these tests have not been fully validated. This randomised trial of clinical decision making based on new troponin tests will provide a guidelines for their efficient and effective use in emergency department care.
A Window Of Vulnerability: Impaired Fear Inhibition In Adolescent Rats

Summary
Adolescence is a period of increased vulnerability to anxiety disorders. The brain undergoes substantial maturation during adolescence, particularly the prefrontal cortex (PFC), a region critical for inhibiting fear. This project examines why fear inhibition is impaired in adolescents and compares the neural mechanisms mediating treatments that enhance fear reduction in adolescence. This research adds new knowledge about novel approaches for early interventions for adolescent anxiety.
A core feature of clinical anxiety is the inability to learn about safety and suppress fear. Impaired safety learning underpins excessive fear responding, overgeneralisation of fear, as well as treatment resistance in clinical anxiety. Very little is known about the brain mechanisms for learned safety. This project maps and manipulates these mechanisms to lay the basic science foundation for the next generation of treatments of anxiety.
Brain Circuits Promoting Abstinence And Preventing Relapse To Alcohol Seeking

Funding Amount
$591,995.00
Summary
This project maps and manipulates the brain circuits that promote abstinence from alcohol use. It uses new techniques from neuroscience to control the activity of specific cell types in discrete brain circuits. In this way we can alter the activity of these circuits to build on the normal neural restorative processes that occur during abstinence from alcohol use to reduce, and possibly prevent, relapse.
Disorder in the circuits that process emotional stimuli are central in the pathogenesis of anxiety disorders. In this grant we will study the circuits that are inolved in fear learnng. Our results will provide the background to developing more effective therapies for a range of anxiety related disorders such as generalised anxiety and post traumatic stress disorder.
A Memory Retrieval - Extinction Procedure To Prevent Relapse To Drug Seeking

Summary
This project shows how relapse to drug seeking can be modulated, and possibly prevented, by novel approaches that manipulate the stability of drug related memories.
Strengthening Frontline Clinicians’ Infection Control: A Multi-method Study To Reduce MRSA Infection And Transmission
Funder
National Health and Medical Research Council
Funding Amount
$800,339.00
Summary
Despite handwashing initiatives and the introduction of alcohol gels, cross-infection in hospitals remains a terrible risk for patients and creates a huge cost for health care funders. This study deploys a video-based technique called video reflexivity to alert frontline clinicians to the infection risks that are inherent in their every practice, educating them to become smarter about such risk.
Enhancing Extinction Of Alcohol-Predicitve Stimuli Through Modulation Of Noradrenergic Signaling

Funding Amount
$374,508.00
Summary
A major obstacle for alcohol-abuse treatment is the high risk of relapse and stimuli previously paired with alcohol use contribute importantly to this risk. Reducing the ability of such stimuli to trigger alcohol-seeking behaviors could significantly improve treatment outcomes. The experiments in the current proposal will develop both behavioral and pharmacological strategies for improving extinction learning with the long term goal of reducing the ability of stimuli to elicit alcohol-seeking.
Problems in learning, memory and other complex mental processes are common to many brain disorders. This project will study the impact of mutations on a family of genes reported in autism and schizophrenia, on complex cognitive behaviours using novel behavioural technologies. This will not only shed fundamental insights into the specific mental processes regulated by these genes and their role in disease, but importantly provide novel targets for the development of therapies.
