Ductal carcinoma in situ represents about 20% of all tumours diagnosed within mammographic screening programs. The natural history of DCIS is poorly understood, as it cannot be observed directly. Estimates of the proportion of DCIS that progress to invasive cancer, as well as factors that may influence progression, are important for clinical management.(More)
BACKGROUND AND OBJECTIVE Uncontrolled bushfires produce copious amounts of smoke that can result in adverse effects on human health and so are important considerations for emergency, public health and environmental protection agencies. During January to March 2003, the north-east and Alpine regions of the state of Victoria experienced major bushfires that(More)
The impact of early childhood traffic-related air pollution (TRAP) exposure on development of asthma and allergies remains unclear. Birth cohort studies are the best available study design to answer this question, but the evidence from such studies has not been synthesized to date. We conducted a systematic review and meta-analyses of published birth cohort(More)
Accurate estimates of future age-specific incidence and mortality are critical for allocation of resources to breast cancer control programmes and evaluation of screening programmes. The purpose of this study is to apply functional data analysis techniques to model age-specific breast cancer mortality time trends, and forecast entire age-specific mortality(More)
In recent years childhood asthma has increased. Although the precipitants of childhood asthma are yet to be established possible contributing factors are local ambient air pollutants. This study aims to assess associations of regional ambient air pollutants on emergency department childhood asthma presentations across four regions of the city of Melbourne,(More)
OBJECTIVE The evidence for the effectiveness of screening is strongest for women ages 50 to 69 years; however, there is variation in the target age group for screening programs between different countries. In particular, there is uncertainty over whether women should continue screening once they reach age 70. We therefore investigated incidence rates for(More)
BACKGROUND The literature regarding the association between breast-feeding and atopic diseases has been contradictory. OBJECTIVE We have assessed the relationship between breast-feeding and atopic disorders in a cohort followed into middle age. METHODS The Tasmanian Asthma Study is a population-based prospective cohort study that has followed(More)
One of the primary adverse effects of long-term use of hormone replacement therapy (HRT) is a modest increase in the risk of breast cancer. Breast tumours that develop in women using HRT have been shown to have prognostically favourable histological features but it is unclear if this is the case for both short- and long-term use. Methods. We evaluated the(More)
OBJECTIVE We sought to examine potential predictors of readmission after coronary artery bypass graft (CABG) surgery. DESIGN/SETTING We analysed routinely collected data of CABG patients who have used the public hospital system of Victoria, Australia from July 1998 to June 2003. In total, 6,627 patients were selected by linking records of elective surgery(More)
The aim of the present study was to examine the influence of childhood respiratory infections on adult respiratory health. In 1992-1994, the European Community Respiratory Health Survey recruited community based samples of 20-44-yr-old people from 48 centres in 22 countries. Study participants completed questionnaires and underwent lung function testing. On(More)
