Joint Longitudinal And Time-to-event Models For Applications In Health Research
Funder

Funding Amount
$86,073.00
Summary
A recently developed statistical technique ("joint modelling") allows for both repeatedly measured biomarker data (for example, blood pressure measurements) and event time data (for example, time until death) to be analysed together. There are several potential benefits to using these models, but since the methods are relatively new their uptake in applied health research remains limited. This PhD will consist of several distinct but interrelated projects which explore the use of these models.
Development Of Statistical Methodologies And Application To Clinical Cancer Studies

National Health and Medical Research Council
Funding Amount
$428,065.00
Summary
Integrating different layers of information coming from the recent ‘-omics’ technologies can help improving the treatment and the prevention of complex diseases. In particular, the identification of molecular markers of different types can be used for better diagnostics and prognosis in cancer and immune diseases. This project will develop innovative statistical solutions to handle and make sense of the vast amount of biological data that are routinely generated in the laboratories.
Novel Pathways Toward Improving Relapse Prediction In Schizophrenia

Funding Amount
$318,768.00
Summary
Relapse is a devastating problem in schizophrenia and our ability to predict when it occurs is still relatively poor. This project seeks to investigate a new method of tracking relapse by measuring speech and symptom changes across time. This novel design is supported by advanced data modelling methods to provide sensitive predictive ability. This project has the potential to significantly improve relapse prediction in schizophrenia and so support and increase beneficial outcomes for patients
Understanding Neurodevelopment In Preterm Children Utilising MRI

Funding Amount
$302,123.00
Summary
Children born very preterm are more likely to have movement, learning and behavioural difficulties resulting from abnormal brain development or injury around the time of birth. This project will help identify common brain alterations in preterm children using MRI, as well as the causes and consequences of such abnormalities. Ideally, this research will help health professionals to prevent abnormalities and injury, or to intervene early to reduce the adverse effects of prematurity.
A Longitudinal Study Of Bacterial Vaginosis And Mycoplasma Genitalium In Young Australian Women.

Funding Amount
$102,270.00
Summary
The aim of this research project is to measure how many Australian women are infected with either bacterial vaginosis or Mycoplasma genitalium. These infections can be associated with significant reproductive complications for women. Very little is know about how common these infections are or how often they can occur. This study will follow 1400 women over 12 months, asking them to provide vaginal swabs through the post for testing for these infections.
Pharmaceutical Opioid Prescription For Chronic Pain In Australia: Trajectories Of Prescribing, Risk Of Adverse Events, And Predictors Of Harm

Funding Amount
$1,086,274.00
Summary
There is concern about rising levels of opioid analgesic prescribing in Australia. This study is important because it will provide evidence about long term outcomes for patients using opioid therapy for chronic non-malignant pain. It will examine prescribing patterns and link them to other health outcomes such as overdose. We will also study patients beginning opioid therapy for chronic pain and follow them up over 2 years to examine outcomes such as pain relief and medication side effects.
Genetic, Family And Social Determinants Of The Burden And Outcome In Rett Syndrome: A Population-based Investigation

Summary
Rett syndrome is a severe disorder of the nervous system mainly affecting females. At birth children with Rett syndrome often seem normal but in their second year lose skills. With time it becomes clear that they are severely intellectually and physically handicapped. In 1999 the link between Rett syndrome and a mutation in the gene, known as MECP2, was found. In Australia since 1993, we have had a register of basic information on all girls and young women diagnosed with Rett syndrome.

With time it becomes clear that they are severely intellectually and physically handicapped. In 1999 the link between Rett syndrome and a mutation in the gene, known as MECP2, was found. In Australia since 1993, we have had a register of basic information on all girls and young women diagnosed with Rett syndrome. Over three quarters of the register s 248 cases have now been genetically tested. In 2000 and again in 2002, extra information on ability to do everyday tasks, behaviour, hand function, medical conditions, and use of health and education services was collected. In 2002 questions on family well being were also included. From 2004 to 2007, further information will be gathered on function, health and well being of the affected child and their family. This will be by telephone interview, questionnaire, video recording, existing medical records, clinical assessments and tests. This will include in 2004 completion of calendars which will provide information needed to estimate health and medical care costs for these children. Similar information by questionnaire and calendar will also be collected from the parents of children with Down syndrome in 2004. The information will be used to compare the social and financial burden of Rett syndrome with Down syndrome, a commoner cause of intellectual disability. The research will also show if it is possible to predict from early genetic test results how severely a child with Rett syndrome will later be affected. It will also determine whether some ways of management improve the long-term outlook for the girl and her family. Finally this study will investigate why some families cope better with this devastating disorder than others. This research is only possible in Australia because of the ongoing register we have set up here.Read moreRead less
Practical Tools For Robust Analysis Of Large Epidemiological Studies With Incomplete Data

Summary
Studies of the causes and consequences of health outcomes follow large cohorts of individuals for long time periods. A major challenge in analysing data from these studies is that information is often incomplete. Participants rarely complete all waves of data collection, or provide all requested information. Statistical research has led to increased use of a statistical method (multiple imputation) that recovers information from incomplete cases. This project will develop and improve this method
