A significant proportion of Australian children are at health risk due to environmental metal exposure. It is suspected that exposure to metals during the prenatal period can result in permanent impairment. Human studies are, however, limited by lack of biomarkers that accurately measure exposure at specific times of intrauterine development. We are proposing to develop a novel method that utilizes human primary teeth to provide a direct measure of metal exposure during foetal development.
Disrupted Neurosteroid Synthesis Mediates The Adverse Effects Of Prenatal Stress

Summary
Maternal anxiety and related stress in pregnancy influences the fetus causing developmental changes that adversely affect the offspring leading to behavioural problems in childhood. However, mechanisms which transfer maternal changes to the fetus are unclear. We propose that disruption of the fetal-placental neurosteroid system is a major link. We will identify the deficits in this system caused by maternal stress and then examine therapies to reverse these disruptions.

Summary
There is evidence that low vitamin D before birth may increase the risk of autism. This study will examine this hypothesis based on a Dutch birth cohort. If there is a link between vitami D and autism, then this can be readily addressed with prenatal supplements.

Summary
Poor oral health during pregnancy can impact the health of the mother and baby. Yet, many expectant mothers are unaware of the implications of poor oral health. In Australia there is a lack of importance being placed on maternal oral health. The aim of this study is to determine the effectiveness of a new service which will promote maternal oral health through collaboration between midwives and dentists. We expect the new service will improve women's oral health, uptake of dental services and po ....Poor oral health during pregnancy can impact the health of the mother and baby.

Summary
Genomic information about unborn children can now be provided using chromosomal microarrays which have the potential to revolutionize maternal care in Australia, but are currently only used in high risk pregnancies. Soon all pregnant women, the vast majority who currently have prenatal screening, will be able to access this and other genomic technologies. We will examine the psychological impact of fetal genomic testing and, in doing so, assess the need for service planning, as well as potential ....Genomic information about unborn children can now be provided using chromosomal microarrays which have the potential to revolutionize maternal care in Australia, but are currently only used in high risk pregnancies.

Epigenetic And Neurobehavioural Changes In A New Mouse Model Of Foetal Alcohol Spectrum Disorders.

Summary
Prenatal alcohol exposure can result in foetal alcohol syndrome (FAS) which involves growth restriction, changes to skull morphology, central nervous system defects and intellectual disabilities. At present, diagnosis is difficult and under-reporting is suspected. We are using a mouse model to study the underlying causes of FAS, focussing on changes in brain structure and function. Hopefully we will identify markers that can be used for the early diagnosis of FAS in the future.
