Summary
This project aims to develop and characterize a novel optogenetic pharyngeal stimulation system to dilate the upper airway using a light stimulus. This will provide proof-of-concept for a new minimally invasive treatment option for obstructive 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.
Mechanisms Of Gastroesophageal Reflux In Obstructive Sleep Apnoea

Summary
The symptoms of gastroesophageal reflux (heartburn and acid burning) are extremely common in individuals with obstructive sleep apnoea (OSA), especially during sleep (nocturnal reflux). The reasons for this are unclear. This research project will investigate the reasons for this increased occurrence of reflux in OSA.
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.
Evaluating The Effect Of Morphine On Obstructive Sleep Apnea

Summary
Prescription opiate poisoning deaths have increased substantially in recent years which may be worsened by population increases in obesity and related obstructive sleep apnea. However, no proper clinical trial has ever investigated the effect of an opiate on obstructive sleep apnea, which is the aim of the proposed trial. The study will be important in understanding ways to reduce opiate realted deaths and may also provide insights into new treatment methods for snoring and sleep apnea.
Prevalence, Phenotype And Genotype Of Common Sleep Disorders

Funding Amount
$1,465,164.00
Summary
There is a critical need for more information on the prevalence and genetic basis of sleep disorders. The proposed study will leverage off data already collected from participants of the WA (Raine) pregnancy cohort, an internationally unique longitudinal study of 2,868 individuals followed over the last 23 yrs with comprehensive assessments starting in utero, continuing through childhood and into early adulthood.The study will replicate this battery of tests in the parents of these young adults.
Obstructive Sleep Apnoea Phenotypes And Treatment In Quadriplegia

National Health and Medical Research Council
Funding Amount
$599,635.00
Summary
Losing function in your arms and legs after an injury (quadriplegia) is a catastrophic event. Quadriplegia also results in obstructive sleep apnoea; a condition where the throat closes repeatedly while asleep causing sleepiness, poor concentration and cardiovascular diseases like stroke. Despite most people with quadriplegia having this disease, the cause is unknown. This project will thoroughly investigate obstructive sleep apnoea causes in people with quadriplegia and test a possible treatment
Clarifying The Pathogenic Role Of Arousal-hyperventilation In Obstructive And Central Sleep Apnoea: Testing Fundamental Pathophysiological Mechanisms And A Strategic New Treatment
Funder
National Health and Medical Research Council
Funding Amount
$414,717.00
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.
Microvascular And Macrovascular Disease In Snoring And Obstructive Sleep Apnoea: A Mechanism For Increased Stroke Risk.
Funder
National Health and Medical Research Council
Funding Amount
$679,744.00
Summary
This project will address the important question of the vascular risk of stroke associated with snoring and obstructive sleep apnoea, by using retinal photography of the eye to directly visualise the vascular changes in the cerebral circulation. Retinal photography may provide a useful clinical tool to help reduce the risk of stroke in patients with snoring and sleep apnoea.
