Summary
This project is designed to understand the mechanisms underpinning much more stable breathing during deep sleep in obstructive sleep apnoea (OSA). A newly developed analytical technique will be used to examine breathing effort changes across sleep, and interactions with respiratory-induced awakenings in OSA patients. In addition, a new treatment designed to stabilise breathing will be tested and refined towards a new treatment option for OSA and for central sleep apnoea.
A New Clinical Tool To Assess Fitness-to-drive In Obstructive Sleep Apnea

Summary
Obstructive sleep apnoea (OSA) affects 1 in 4 middle aged adults. OSA results in impaired neurobehavioral function, excessive sleepiness, and more than 2-fold increased motor vehicle crash risk and workplace accidents. However, not all patients are impaired and identifying patients at risk is a daily clinical challenge. This project proposes new and simple measures that can accurately identify patients with OSA who are most vulnerable to alertness failure and motor vehicle accident risk.
Clinical Outcomes, Safety And Incremental Cost Effectiveness Of Multi-level Airway Surgery In Patients With Moderate-severe Obstructive Sleep Apnea (OSA) Who Have Failed Medical Management

Summary
Obstructive sleep apnoea (OSA) is a serious medical disorder with a high public health cost. OSA can be effectively treated but poor treatment compliance is a major clinical problem. As a consequence many OSA patients remain untreated, with significant implications for their long term health. New effective and safe therapies are needed. We believe that we will demonstrate a relatively straightforward, safe and effective surgical procedure for OSA after primary treatments fail. This will lead to ....Obstructive sleep apnoea (OSA) is a serious medical disorder with a high public health cost.

There’s recent evidence that children get leaner and fitter during the school term, but become fatter and less fit over the summer holidays. This may be because of differences in activity and diet: on holidays, children may eat more, be less active and have more screen time. We propose to track the time use, diet, fitness and fatness of 9-11 year old children across three school years. If the pattern is confirmed, we should focus more on the home environment, or perhaps encourage summer camps.
The Clinical Effectiveness Of A Simple New Treatment For Supine-dependent Obstructive Sleep Apnoea

Summary
Obstructive sleep apnoea is a common and debilitating breathing problem in sleep with serious effects on sleep and health. A third of patients could be very simply treated by avoiding sleeping on their back. Existing treatments are uncomfortable, often not used and better options are needed. This project will test symptom relief and treatment adherence with a new comfortable low cost supine avoidance therapy against current best practice treatment.
Health Impacts Of Sleep Apnea In Australian Men- A Longitudinal Population Study.

Summary
Obstructive sleep apnea (OSA) is very common, seen in 60-70% of men over 40 years old. OSA is linked to a number of serious conditions, e.g. heart disease and diabetes. However, we don't know which men are at risk of long term complications from OSA. Our aim is to follow-up men from a community sample of 1000 men who had sleep studies in 2010 to help identify who is at risk of poor health from OSA.
Treating Insomnia Co-morbid With Obstructive Sleep Apnoea: A Randomized Controlled Clinical Effectiveness Trial.

$600,869.00
Summary
Obstructive Sleep Apnoea (OSA) is a common but serious sleep disorder. Continuous positive airways pressure (CPAP) therapy can be very effective in treating OSA. We have found that many patients with OSA also suffer from insomnia, and this can make it hard for them to begin CPAP therapy and hard for them to stick to it. This trial will examine the effect of treating insomnia concurrently with CPAP, with the expectation that overall treatment outcomes will improve.
Histone Demethylase KDM6A Is A Novel Target For Treating Craniosynostosis In Children With Saethre-Chotzen Syndrome

Summary
Children with Saethre-Chotzen syndrome exhibit premature fused coronal sutures, and other skull/ skeletal malformations. Surgical intervention is the only treatment option to ensure optimal cognitive and skeletal development. Our studies have identified a candidate molecular pathway that regulates bone formation by cranial bone cells from these patients. Targeting this key molecular regulator with chemical inhibitors will help prevent the premature fusion of cranial sutures.
Cerebral Palsy (CP) is a devastating, common developmental brain disorder once assumed to be due to lack of oxygen at birth. Using our unique Biobank with DNA and clinical data from families with a CP child, we are examining the genetic origins of CP and how genes and risk factors in pregnancy contribute. We will use computer modelling and testing in animals and brain cells, to understand causes of CP and devise predictive, preventative and therapeutic strategies.

Summary
Children with Saethre-Chotzen syndrome exhibit premature fussed coronal sutures, and other skull/ skeletal malformations. Surgical intervention is the only treatment option to ensure optimal cognitive and skeletal development. Our studies have identified a candidate molecular pathway that regulates bone formation by cranial bone cells from these patients. Targeting these key molecular signalling components with chemical inhibitors will help prevent the premature fusion of cranial sutures.
