Quit In General Practice: A Cluster Randomised Trial Of Enhanced In-practice Support For Smoking Cessation
Funder

Funding Amount
$1,117,241.00
Summary
Tobacco smoking remains the most common preventable cause of death and illness in Australia today. Smoking cessation programs are some of the most effective and cost effective strategies that can be undertaken in health care settings, including general practice. This project will test a new approach to supporting smoking cessation in general practice. This involves the practice nurse, GP and Quitline working in partnership to provide a flexible program of suport to meet the needs of smokers.
The Role Of Redox-related Post-translational Changes Of Complement Factor H (CFH) In Age-related Macular Degeneration

Summary
Patients with AMD experience loss of central vision and this disorder is the leading cause of blindness in those aged over 50 years in Australia. There are currently no effective treatments for dry AMD. We have identified a protein that undergoes a modification in the blood and the eyes of humans with AMD that has given us new insights into how AMD develops. Specific therapies targeting this modified protein may offer a new treatment for this important cause of blindness.
Pathophysiological Correlates In Smokers And Smoking-related Chronic Obstructive Pulmonary Disease (COPD)

Summary
Smoking-related chronic airway narrowing (COPD) is a common and major illness. Research on the characteristics of the actual pathological process in the airways in smokers and COPD using direct tissue sample is relatively new. Data is currently limited and rather contradictory. In this grant we will recruit a spectrum of smokers and COPD patients typical of those in the Australian community and will be undertaking a detailed analysis of the cellular and some vascular structural changes in the ai ....Smoking-related chronic airway narrowing (COPD) is a common and major illness. Research on the characteristics of the actual pathological process in the airways in smokers and COPD using direct tissue sample is relatively new. Data is currently limited and rather contradictory. In this grant we will recruit a spectrum of smokers and COPD patients typical of those in the Australian community and will be undertaking a detailed analysis of the cellular and some vascular structural changes in the airway wall. Both cellular and vascular changes will be related to the fixed and reversible component of airway obstruction. Reversible changes with smoking cessation will be studied. A very novel feature will be a preliminary assessment of the utility of proteomics for assessment of airway pathology.Read moreRead less

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.

Identification And Therapeutic Modulation Of Sphingolipids As Novel Lung Macrophage-targeted Treatments For COPD/emphysema

Summary
COPD/emphysema is predicted to be the third leading cause of death woldwide by 2010. We have shown defective lung macrophage function in COPD and have shown that we can modify the macrophage function with novel therapies. We are now investigating a specific “sphingosine” pathway to see if it can provide us with more specific information. We aim to provide a better, more specific, adjunct treatment for the disease.
COPD is a smoking-related airways disease that costs the Australian community over $8.8 billion/yr. It is predicted to become the third most common cause of death in the world by the year 2020 and is linked to an increased risk of lung cancer. There are no effective treatments for COPD. I have been working with a number of anti-inflammatory treatments in a smoking mouse model and will extend my research to see if these treatments can be optimised to treat COPD.
Low-yield Cigarettes And Diminution Of Small Airways Lung Function In Long-term Smokers

Summary
The modern cigarette has been designed to produce low yields of tar when the tobacco in the cigarette is burnt. The tar contains human carcinogens, and monitoring and regulating yields of tar has long been part of the comprehensive tobacco control strategy in Australia. This focus on tar has given an implicit endorsement of the low-yield cigarette as a safer cigarette. Recently, however, controversy has emerged about whether smoking low-yield cigarettes has reduced the harm done by smoking. The ....The modern cigarette has been designed to produce low yields of tar when the tobacco in the cigarette is burnt. The tar contains human carcinogens, and monitoring and regulating yields of tar has long been part of the comprehensive tobacco control strategy in Australia. This focus on tar has given an implicit endorsement of the low-yield cigarette as a safer cigarette. Recently, however, controversy has emerged about whether smoking low-yield cigarettes has reduced the harm done by smoking. The concern is that adenocarcinoma of the lung, a type of lung cancer that is most common in the small peripheral airways, has increased in frequency. This could be because the low-yield cigarette, with reduced yields of nicotine as well as tar, is smoked more intensely by smokers to compensate for the low nicotine. By smoking more intensely, we mean taking larger and more frequent puffs, inhaling the smoke deeply into the lungs, and holding the breath before expiring. This method of smoking would result in more tar particles being deposited in the peripheries of the lung where adenocarcinoma is most common. Because cigarette smoking has been linked also with other structural changes in the small airways of the lung, resulting in obstruction of airflow, we will test whether smoking low-yield cigarettes is associated with greater obstruction of the small airways than is smoking higher-yield cigarettes. To test whether the mechanism is the method of smoking, we will carefully describe and quantify each subject's pattern of smoking including the deposition of smoke-like Technegas particles in the peripheral lung.Read moreRead less
Determine The Role Of The SAA-Macrophage Axis On Respiratory Pathogen Clearance In Smoke Exposure Related Lung Disease.

Summary
Direct or second hand exposure to tobacco smoke significantly increases your risk of acquiring a chest infection. Infants and elderly smokers are particularly susceptible. This will continue to be a major global problem as household smoke exposure remains high in developing countries and disadvantaged indigenous communities. We will investigate how smoke alters important immune cells that normally clear lung infections, which may lead to completely new ways of treating chest infections.
Modifying Epigenetics As A Novel Treatment In COPD

Funding Amount

Summary
Smoking leads to inflammation that causes emphysema, which is a major health problem. Once induced there is a progressive decline in health, which continues even after stopping smoking. There are no treatments that halt this decline. Recently smoking-induced changes in genes have been discovered that control inflammation. We may be able to reverse these changes and stop the induction and progression of emphysema. This project may lead to a completely new way of preventing and treating emphysema.
Randomised Controlled Trial Of A Financial Counselling Intervention And Smoking Cessation Assistance To Reduce Smoking In Socioeconomically Disadvantaged Groups
Funder

Funding Amount
$2,029,662.00
Summary
Socioeconomically disadvantaged groups are more likely to smoke than other sectors of the community. This difference has been attributed, in part, to increased rates of relapse. Relapse is strongly and consistently predicted by financial stress. This project attempts to reduce relapse by reducing financial stress among disadvantaged smokers through the provision of financial counselling as an adjunct to NRT.
