Summary
People with cystic fibrosis (CF) produce thick mucus that is not cleared normally from the lungs. This retained mucus often becomes infected, which progressively damages the lungs. Various physical therapies which may help clear secretions are being used in CF. These include several types of devices which provide positive pressure to the airways. However, it is not known to what extent these devices, or other interventions such as manual chest physiotherapy and exercise, enhance mucus clearance. ....People with cystic fibrosis (CF) produce thick mucus that is not cleared normally from the lungs. This retained mucus often becomes infected, which progressively damages the lungs. Various physical therapies which may help clear secretions are being used in CF. These include several types of devices which provide positive pressure to the airways. However, it is not known to what extent these devices, or other interventions such as manual chest physiotherapy and exercise, enhance mucus clearance. As a result, it is not currently possible to scientifically prescribe intervention(s) to enhance mucus clearance in CF. This is partly because much of the research that has been performed in this area has been poorly-designed or has used inaccurate measures. Also, recent research has shown that these therapies may have significant effects beside their effect on mucus clearance. For instance, bacterial infection and the exchange of oxygen and carbon dioxide between the blood supply and air in the lung may all be affected by these interventions. Notably, the extent of benefit or detriment seen in these parameters does not always correlate with the effect on mucus clearance. We therefore believe a series of experiments is necessary to provide evidence upon which the scientific selection of mucus clearance therapies may be based. We have developed a new technique which allows clearance of mucus from the airways to be objectively measured in three-dimensions (3D). We intend to use the 3D technique to examine the effects of three different positive pressure devices, exercise, and manual chest physiotherapy on mucus clearance. Based on the outcomes of this research, we intend to compare the most appropriate therapy to performing no mucus clearance therapy in a short term trial. This trial will assess changes in the following: bacterial infection, mucus plugging in the airways, how well the lungs move air and exchange oxygen and carbon dioxide, and the patient's quality of life.Read moreRead less
Why Does Peripheral Airway Dysfunction Lead To Broncholitis Obliterans Syndrome In Lung Transplantation?

Summary
The uneven way that airways narrow (heterogeneity) is an important factor affecting the natural history, clinical expression and response to treatment in patients following lung transplantation. In the proposed study we plan to monitor the heterogeneity of the airways in patients immediately following lung transplantation and relate these changes to immunological markers of lung rejection.
Towards An Improved Understanding Of The Effect Of A Speaking Valve On Lung Volumes And Communication In The Critically Ill Tracheostomised Patient

Summary
Patients that require life support in intensive care often have breathing tubes in their neck. This means they are generally left without a voice for days, weeks, even months. Speaking valves meant for talking are not used much due to fears of harm to the lungs. Our study is looking at how much air is in the lungs when using this valve. Data so far suggest that the valve is in fact helping the lungs. The outcomes of this study may lead to most of these critically ill patients having a voice.
Neural Control Of Human Respiratory Muscles In Health And Disease

Funding Amount
$450,132.00
Summary
This research examines how human inspiratory muscles that ‘pump’ air into the lungs are controlled in health and disease. We will study the interaction between automatic and voluntary control of breathing, about which very little is known. The control of breathing in patients who breathe against an inspiratory load (eg. asthma) and mechanically ventilated patients will be a focus of this research. Outcomes include better understanding of the control of breathing and improved patient care.
Intensive Care Management And Quality Of Survival Of Acute Respiratory Distress Syndrome

Summary
Acute respiratory distress syndrome (ARDS) is a severe inflammatory condition of the lungs that complicates many critical illnesses and is associated with high mortality and morbidity. Although intensive care admission and mechanical ventilation provide life-saving support during ARDS, they can lead to poor long term outcome. The aim of this program is to compare the clinical efficiency of new strategies in ICU to that of current standard care and to improve the quality of survival of patients w ....Acute respiratory distress syndrome (ARDS) is a severe inflammatory condition of the lungs that complicates many critical illnesses and is associated with high mortality and morbidity.

Improving Health-related Quality Of Life In Patients Receiving Home Mechanical Ventilation

Funding Amount
$121,793.00
Summary
Home mechanical ventilation (HMV) is a treatment that assists someone to breathe using a machine. People may need HMV when their breathing has failed due to conditions such as chronic obstructive pulmonary disease (COPD), neuromuscular disease (NMD) or severe obesity. This project will examine the quality of life of patients receiving HMV in Australia and Canada. It will also determine if we can improve the treatment by using a sleep study to monitor breathing when patients first start HMV.
Improving Neonatal Transition For Compromised Infants And Minimising Lung Injury

Summary
The projects in this proposal are designed to improve the health of newly born infants before they are born (fetal lactate blood test to assist in decision making), at birth (randomized clinical trials to provide evidence for future resuscitation guidelines) and in the first few hours following preterm birth by studying alternative methods of providing existing therapies for neonatal respiratory distress syndrome. These studies may prevent harm and allow a “Healthy start to life”.
Understanding And Improving Treatment Of Premature Infants To Improve Long Term Outcomes

Funding Amount

Summary
The last 2 decades heralded many important advances in the care of preterm infants but important gaps in our knowledge remain. Studies undertaken in the preclinical and clinical settings during this Fellowship will enhance understanding of the complex nature of disease in preterm infants. Further, we will develop and evaluate new treatments that enhance growth and development of the premature baby to optimise their long term intellectual, physical, emotional and social outcomes.
