Summary
Sleep disordered breathing (SDB)affects up to 15% of women during pregnancy. There is some evidence that it may have adverse effects on both mother and baby, particularly it may be associated with a 7-8 fold increase risk of developing hypertension during pregnancy. This study aims to measure breathing during sleep in pregnant women to determine its role in pregnancy-related hypertension and diabetes, then treat the SDB to assess its effect on maternal and foetal outcomes.

Summary
Obstructive sleep apnoea (OSA) is a very common disorder, affecting approximately 2% of women and 4% of men in the middle-aged workforce . It is characterised by repetitive, complete or partial closure of the throat passage during sleep, resulting in sleep disturbance and low oxygen levels. OSA is recognised as a serious public health problem. There is growing evidence supporting the use of oral appliances to treat OSA.

It is characterised by repetitive, complete or partial closure of the throat passage during sleep, resulting in sleep disturbance and low oxygen levels. OSA is recognised as a serious public health problem. There is growing evidence supporting the use of oral appliances to treat OSA. It is thought that these work by enlarging the throat passage, but this remains uncertain. The aim of this project is to gain a better understanding of how such appliances work, so as to be able to predict which patients will particularly benefit from this form of treatment.Read moreRead less
Surfactant Protein D As A Candidate Therapy In COPD

Summary
Smoking -related chronic bronchitis and emphysema, otherwise known COPD, costs the healthcare system over $800 million per year. People continue to suffer even after they have given up smoking, and the treatments available result in only modest improvements. COPD is associated with a a defect of the scavenging cells in the lung, which normally clear away dying cells, and some of the proteins ivolved in this process. We will investigate whether supplementing these proteins will help.
Obstructive Sleep Apnea And Androgen Dysregulation

Summary
Obstructive Sleep Apnea (OSA) is a serious public health problem associated with increased sleepiness, heart disease and metabolic dysfunction. Obesity and male gender are important predisposing factors for OSA. This study will determine if short-term testosterone therapy can help improve OSA in men who are also dieting and exercising. It will also determine the genetic mechanisms by which testosterone might influence breathing during sleep and obesity.

Summary
Chronic obstructive pulmonary disease (COPD) is a major global health problem and has been predicted to become the third largest cause of death in the world by 2020. Cigarette smoking is the major cause of COPD and accounts for more than 95% of cases in industrialized countries. Currently no therapies exist to halt the inevitable progression of the disease.

Cigarette smoking is the major cause of COPD and accounts for more than 95% of cases in industrialized countries. Currently no therapies exist to halt the inevitable progression of the disease. To date most of the research has focused on the aspects of this disease which result in destruction of the lung however it is becoming increasingly evident that COPD is a disease of multiple organs. Until recently it had been widely believed that the profound loss of exercise tolerance observed in COPD patients was due to impaired gas exchange secondary to lung structural damage. Loss of lean body mass (muscle) is now recognised as a major co-morbidity of COPD and a direct cause of functional impairment with patients suffering marked deteriorations in quality of life, increased mortality, breathlessness and decreased exercise tolerance. Skeletal muscle wasting is a powerful predictor of mortality in COPD, independent of the lung function impairment. Despite the clinical seriousness of muscle wasting and suggestive evidence that it may be reversible, little is known about the pathogenic mechanisms. Therefore the goal of this project is to use experimental models of COPD to identify the molecular basis of wasting, in order to restore skeletal muscle homeostasis. The insights gained from this research proposal may lead to the identification of potentially novel targets for the prevention and reversal of the debilitating and life threatening effects of skeletal muscle wasting in COPD. For the COPD patient this has the potential to increase quality of life, functional ability and life expectancy.Read moreRead less

Summary
Chronic obstructive pulmonary disease (COPD) is a complex, chronic disease of the lungs principally caused by cigarette smoking. COPD is very common and causes a great deal of debility and mortality in our community. COPD is also linked to an increased risk of lung cancer and carviovascular disease. It is estimated to cost Australians at least $800 million dollars per year in health related costs. Despite its importance, there is a limited understanding of how COPD develops and treatment options ....Chronic obstructive pulmonary disease (COPD) is a complex, chronic disease of the lungs principally caused by cigarette smoking. COPD is very common and causes a great deal of debility and mortality in our community. COPD is also linked to an increased risk of lung cancer and carviovascular disease. It is estimated to cost Australians at least $800 million dollars per year in health related costs. Despite its importance, there is a limited understanding of how COPD develops and treatment options are limited. We have identified large numbers of dying cells in the airways of people with COPD and we believe that these play a critical part in the cause and-or progression of the illness. This project will determine whether the increased rates of cell death are the result of the COPD process or part of the actual cause of the disease. This knowledge will enable us to address the urgent need to predict the risk of developing COPD in current and ex- smokers. Cells obtained from the lungs of healthy controls, current- ex smokers without COPD and current- ex smokers with COPD will be studied. The effects of current treatments for COPD on these cells as well as testing novel treatments will also be studied, paying particular attention to the effects on cell death. In this way we hope that new therapies will be identified to improve the health and well-being of those with COPD.Read moreRead less
The Diagnosis Of Obstructive Sleep Apnea In Primary Care

Summary
The gold standard method for diagnosis of sleep apnea is the overnight sleep study. These tests are expensive, have long waiting lists and are hard to access outside larger cities. We aim to determine if general practitioners can combine information from questionnaires and a simple home diagnostic test, to confirm or rule out sleep apnea. The results of this study will eventually lead to more accessible and efficient diagnosis and treatment of this common condition.
The Effect Of CPAP On Erectile And Endothelial Dysfunction In Impotent Men With Obstructive Sleep Apnea

Summary
Erectile dysfunction is common in men with obstructive sleep apnea, due to vascular damage, which leads to heart attack. CPAP is the preferred treatment for patients with OSA because of its well-proven ability to decrease sleepiness and improve blood pressure control. This study will establish if CPAP can also improve erectile and vascular endothelial dysfunction. These results will shed light on the mechanisms that underpin the relationship between OSA and Erectile Dysfunction.
