Summary
During sleep, patients with heart failure often exhibit a cyclic pattern of breathing in which a period of regular breathing alternates with a period when breathing ceases. This breathing pattern is associated with increased mortality and reduced quality of life but to date no effective treatment for it exists. We have developed a method to calculate an exact level of carbon dioxide to stabilise breathing in each individual, offering the prospect of a better night’s sleep and a longer life.
THE EFFECT OF LONG ACTING BRONCHODILATORS ON VENTILATION IN COPD

Summary
COPD is a common and important smoking-related lung disease. Well-established treatments with inhaled medications including long-acting bronchodilators have a proven clinical track record. However the physiological basis for their effects is still under investigation. This research examines some of the physiological changes in lung function and the response to long-acting bronchodilators in patients with COPD, and may help explain why some patients respond to therapy while others do not, leading ....COPD is a common and important smoking-related lung disease.

Mucous In Heterogeneous And Progressive Early Cystic Fibrosis Lung Disease

Funding Amount
$347,948.00
Summary
Cystic fibrosis (CF) is the most common genetically acquired, life-shortening chronic illness affecting young Australians today. Individuals with CF have a reduced ability to clear mucous from the airways resulting in respiratory infections and inflammation. This project will quantify the biochemical and biophysical properties of mucous in young children with CF to generate novel insights into the pathogenesis of early disease, biomarkers of disease progression and therapeutic targets.
The Role Of Tissue Hypoxia In The Evolution Of Kidney Disease

Summary
We will determine how low oxygen levels in the kidney lead to kidney disease. We can now measure the levels of oxygen in kidney tissue in rats 24 hours a day, 7 days a week, in a completely non-invasive way. We will study two common kinds of kidney disease. One, acute kidney injury, can result from administration of contrast agents used in x-ray diagnostic procedures. The other, chronic kidney disease, is common in patients with diabetes or high blood pressure.
Towards Prevention Of Acute Kidney Injury After Cardiac Surgery

Summary
Open heart surgery saves thousands of lives each year in Australia, but often injures the kidney. Kidney oxygen deficiency is a major cause of kidney injury. We propose a new way to manage kidney oxygen levels during heart surgery, by measuring the level of oxygen in the urine in the bladder. We will determine whether low levels of oxygen in the urine during surgery predict later development of acute kidney injury, and whether patient management can be changed to optimize kidney oxygen levels.
Assessing a model of the physiological changes at arousal from sleep. Arousals from sleep are common in the elderly and have adverse consequences. This project will investigate a model of the changes in bodily processes (muscle, brain and cardiovascular activation) that occur when humans awaken from sleep.
Dysfunction of the nervous system plays an important role in the symptoms of many respiratory diseases. For example, excessive non-productive coughing, elevated mucous secretion, reduced airway patency and hyperreactivity are all characteristic symptoms of diseases such as asthma and all involve over-activity of the nervous system. This research aims to understand the neural circuitry that is involved in controlling the airways and the mechanisms that underlie how this circuitry can become dysfu ....Dysfunction of the nervous system plays an important role in the symptoms of many respiratory diseases.

Patients With Obstructive Sleep Apnoea And Motor Control

Funding Amount
$302,798.00
Summary
Obstructive Sleep Apnoea is a major health concern, affecting at least 4% of the population, associated with obesity, and aging. The symptoms of sleep apnoea are definitively associated with cardiovascular complications. I am focused on understanding how sleep apnoea patients are remodelled with the rewiring of connections between the brain and muscles. Using neurophysiological techniques, this project will study how the anatomy and functional connections of circuits change with sleep apnoea.
Combined Therapy To Ameliorate Ventilatory Instability In Patients With Heart Failure And Sleep Apnea

Funding Amount
$386,648.00
Summary
Sleep apnea is highly prevalent, particularly in patients with heart failure, and treatment remains limited to applying pressure via a face mask which can be intolerable. Although instability in breathing control is a major cause of apnea in many patients, treatments targeting instability with sufficient efficacy are unavailable. This project will combine two treatments, acetazolamide and oxygen, to powerfully reduce instability and provide relief from sleep apnea in a subgroup of patients.
Optimising Lung Surfactant Protein Production In The IUGR Fetus At Risk Of Preterm Delivery

Summary
Pregnant women at risk of preterm labour after 24 weeks gestation are increasingly administered glucocorticoids in Australian hospitals in order to promote fetal lung maturation and a successful transition to extrauterine life. Antenatal glucocorticoid treatment reduces overall neonatal mortality, the risk of respiratory distress syndrome and the need for respiratory support. Babies that are born small may not benefit from this treatment in the same way that average size babies benefit.
