X-ray Micro-tomography Validation of HRCT-Based Airway Measurements. This project brings together a newly emergent modality of microscopy in the form of 3D X-ray micro-tomography (XRMT) along with leading-edge image analysis to develop breakthrough science in respiratory research aimed at improving the reliability of high resolution computed tomography (HRCT). The project will develop novel 3D lung image segmentation protocols, a stereotactic registration program allowing 3D matching of XRCT and ....X-ray Micro-tomography Validation of HRCT-Based Airway Measurements. This project brings together a newly emergent modality of microscopy in the form of 3D X-ray micro-tomography (XRMT) along with leading-edge image analysis to develop breakthrough science in respiratory research aimed at improving the reliability of high resolution computed tomography (HRCT). The project will develop novel 3D lung image segmentation protocols, a stereotactic registration program allowing 3D matching of XRCT and HRCT data sets, and a validation protocol for quantitative HRCT analysis of airway disease. These outcomes will allow wider application of HRCT to non-invasively follow the dynamics of pulmonary function.Read moreRead less
Mechanisms Of Apnea And Periodic Breathing In The Newborn.

Summary
Breathing pauses referred to as apnea or periodic breathing occur frequently in the preterm infant, and often require intensive clinical vigilance to ensure survival. And yet the mechanisms that produce and terminate apnea are not understood. This study will investigate the mechanisms underlying infantile apnea and periodic breathing and the effectiveness of drugs and techniques currently used to control apnea by using a combination of infant animal model studies, mathematical modelling studies ....Breathing pauses referred to as apnea or periodic breathing occur frequently in the preterm infant, and often require intensive clinical vigilance to ensure survival. And yet the mechanisms that produce and terminate apnea are not understood. This study will investigate the mechanisms underlying infantile apnea and periodic breathing and the effectiveness of drugs and techniques currently used to control apnea by using a combination of infant animal model studies, mathematical modelling studies and studies in human preterm infants to improve our understanding of breathing control in infancy.Read moreRead less
Genetic And Environmental Factors And Early Lung Problems Can Be Related To Allergy And Poor Lung Development In Preschool Age Children

Funding Amount
$122,032.00
Summary
This important new collaboration between the Murdoch ChildrenÍs Research Institute and Barwon Health explores the impact of early lung development on longer term respiratory health. It utilises a newly validated, accurate and safe technique to measure lung function in young babies and children. Data on environmental factors and lung function will help us explore the risk factors for the development of allergy, asthma and lung infections in early life.
Development Of An Effective Therapy For Cheyne-Stokes Breathing In Heart Failure.

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.
Targeting Cystic Fibrosis Using A Novel Inhalation Therapy

Funding Amount
$421,545.00
Summary
Currently treatments for cystic fibrosis infection are via oral, intravenous or lengthy inhalation processes. This can lead to significant side effects, consequent poor patient compliance, and limited therapeutic efficacy. We will develop and test a novel high-dose inhalation dry power device containing an antibiotics for the rapid treatment of infection in cystic fibrosis therapy.
First-in-human Evaluation Of A Novel Immunobiotic To Prevent Respiratory Infection

Funding Amount

Summary
Respiratory infections are a leading cause of death and illness throughout the world. We have discovered a 'friendly' bacteria that can be applied up the nose to prevent ear infections and the 'flu in mice. We will now test this novel therapy in humans to check it is safe and that it stimulates the human immune system in the same way that it does in mice. This will provide essential information to conduct clinical trials, with the aim to produce a medicine that prevents respiratory infections.
Breathe Well: A Centre For Research Excellence In Chronic Respiratory Diseases And Lung Ageing

National Health and Medical Research Council
Funding Amount
$2,527,082.00
Summary
Our CRE is based on common respiratory conditions covering wide spectrum of ages and severity. We will investigate how to maintain optimal respiratory health, through innovative approaches to early detection, improved therapy and adherence. We have a strong multi-disciplinary team of collaborators and we will build capacity through post-doctoral fellowships to improve our structural balance and optimise translational outputs. Tasmania is an ideal community to host a strong CCRE.
Non-invasive Methods Of Measuring Work Of Breathing In Children

Summary
Sleep-disordered breathing such as obstructive sleep apnoea, is currently diagnosed if a child stops breathing more than once per hour. For children with asthma or cystic fibrosis, who may not stop breathing during the night, how hard their breathing muscles work can have a significant impact on their health. A non-invasive method of measuring respiratory effort, and incorporating this measurement into how sleep-disordered breathing is diagnosed, can revolutionize how sleep-disordered breathing ....Sleep-disordered breathing such as obstructive sleep apnoea, is currently diagnosed if a child stops breathing more than once per hour.
