Summary
The overall objective of this project is to produce new knowledge about effective strategies for decreasing the smoking rates in pregnant Aboriginal women. The studies aim to: 1. Understand pregnant Aboriginal smokers attitudes to and experiences of using quit smoking methods 2. Understand what behaviour change techniques may be useful for pregnant Aboriginal women who smoke 3. Explore clinicians’ knowledge, attitudes and practices of providing behavioural counselling and nicotine replacemen
The health effects of electronic cigarette use are virtually unknown. They have only recently been introduced into widespread use, and as such their effects on human health will not be known for many years. We will use our expertise in exposure models and health outcome measurement to provide timely hard-data on their potential to impact health – data that are urgently required to guide policy makers in this area.
An Open-label Randomised Pragmatic Policy Trial Of Nicotine Products For Short-term Cessation Assistance Or Long-term Substitution In Smokers.

Funding Amount

Summary
Many smokers who try to quit fail in their attempt. Medicinal nicotine is currently only used as a short-term quit aid. This trial will test if offering smokers the option of using these products as long-term substitutes for cigarettes will help more smokers to successfully quit. We will also determine if offering smokers low toxicity smokeless tobacco and electronic nicotine devices in addition to medicinal nicotine products further increases the number of smokers who quit successfully.
Alveolar Macrophage Zinc And Zinc Transporters And Their Role In Phagocytosis

Summary
Zinc is an essential dietary component that serves a number of functions in the lungs. It is both an anti-oxidant and anti-inflammatory agent. Some airway inflammatory diseases such as emphysema may involve a critical loss of lung zinc. We believe that cigarette smoke causes the loss of zinc and this prevents the lung macrophages from working properly to clear bacteria and dead cells. This will provide a foundation for our long term goals of better clinical management of emphysema.
Understanding The Impacts Of Vaporised Nicotine Products On Smoking In Australia

Funding Amount
$1,603,159.00
Summary
Vaporised nicotine products (e.g., e-cigarettes) are widely used in Australia, even though possession of the nicotine fluid without a permit is an offence. They are primarily used by smokers as a means of quitting. However, there is concern about their potential attractiveness and uptake by non-smokers. The aim is to identify how these products might be used to both maximise smoking cessation and minimise nicotine use, especially smoking uptake by non-smokers.
Elucidation Of The Aetiology Of Airway Remodelling In COPD

Funding Amount
$626,979.00
Summary
This project grant aims to discover how cigarette smoking induces the development of Chronic Obstructive Pulmonary Disease (COPD) by understanding how smoking drives the key pathological charges in the airways, airway remodelling. Our research to-date has found that cells from people with COPD have an hightened response to cigarette smoke and we aim to uncover the molecular basis of this aberrant response.
Modifiable Influences On Tobacco, Cannabis And Other Drug Use In Early Adolescence.

Funding Amount
$198,434.00
Summary
High rates of tobacco and cannabis use by Australia s young people are a continuing concern. This study will explore the factors that influence the development of drug use from late childhood. The International Youth Development Study collected data from 5,769 students in Grades 5, 7, and 9 in Washington State, U.S., and Victoria, Australia. Findings will both increase understanding of adolescent tobacco and cannabis use in the Australian context and inform prevention policy.
Interleukin-17A Promotes Cigarette Smoke-induced Lung Inflammation And Damage

Summary
Emphysema 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 emphysema and accounts for more than 95% of cases in industrialized countries. Cigarette smoke triggers cells in the lung to release substances which cause inflammation and "eat away" lung tissue. The aim of this project is to identify therapies to prevent and treat emphysema.

Cigarette smoking is the major cause of COPD and accounts for more than 95% of cases in industrialized countries. Cigarette smoke triggers cells in the lung to release substances which cause inflammation and eat away lung tissue. In addition, these substances enter the blood and muscle where they eat away muscle resulting in significant weight loss. Patients with COPD have severe difficulty in breathing because the lungs are damaged and do not function properly. This process, once started, cannot be reversed and there is currently no satisfactory therapy to help treat individuals with this terrible disease. People with COPD are prone to viral and bacterial infections of the lungs. These infections cause further inflammation, lung damage and difficulty in breathing. These infections place a tremendous burden on health care resources, have a huge effect on the quality of life and are a common cause of death. The reason why respiratory infections are so serious for people with COPD is unclear. Preliminary results from our laboratory show that a substance called GM-CSF, released from cells in the lung, may be involved in the development of COPD. Thus, the aim of this project is to use our mouse models of COPD to determine whether GM-CSF is involved in the development of COPD. The insights gained may lead to the identification of potentially novel ways to prevent and treat COPD.Read moreRead less
