Summary
Brain damage in the newborn - particularly in prematurely born infants - remains a significant health problem. At present there are very few treatments that can be used to minimize damage when it becomes apparent in the newborn, and none that can be used PROSPECTIVELYduring pregnancy to protect the developing brain from damage. The most likely cause of damage to the fetal brain during pregnancy or at birth is global ASPHYXIA, either by itself or in association with other problems of pregnancy su ....Brain damage in the newborn - particularly in prematurely born infants - remains a significant health problem. At present there are very few treatments that can be used to minimize damage when it becomes apparent in the newborn, and none that can be used PROSPECTIVELYduring pregnancy to protect the developing brain from damage. The most likely cause of damage to the fetal brain during pregnancy or at birth is global ASPHYXIA, either by itself or in association with other problems of pregnancy such as infection, preterm birth, or fetal growth retardation. In this project we propose that providing extra amounts of the dietary constituent creatine, or of the hormone melatonin, to the pregnant animal in late gestation, will provide NEUROPROTECTION to the developing brain in the face of an asphyxial challenge that otherwise causes damage. We will use pregnant sheep to investigate the effects of asphyxia in utero on the fetal brain using techniques that allow us to monitor metabolic changes within the brain in real time. In addition, we will use the pregnant Spiny Mouse to investigate the effects of birth asphyxia on the postnatal brain structure and behavioral development. We will study groups of animals fed a normal diet, and compare then to animals that receive additional amounts of creatine or melatonin. We expect to determine if either of these treatments have the potential to protect the developing brain from asphyxial damage, and to recommend if similar treatments could be used in pregnant women where the obstetrician suspects the baby's brain is at risk of damage.Read moreRead less
Roles Of PTHrP And Calcium In Mammary Function In Perinatal Growth Restriction

Summary
Babies that are born small have significant problems around the time of birth and may have limited catch-up growth. A recently discovered protein known as PTHrP influences the nutrition of the growing newborn through breast milk. Because of its potential importance to small babies we intend to study this protein during and after pregnancy in rats and their pups. New treatments may emerge from the knowledge gained from these studies that may improve the growth and health of infants.
Perinatal Exposure To Household And Environmental Toxins And The Risk Of Asthma And Allergic Disease Up To 25 Years

Summary
Perinatal exposure to household and environmental toxins may increase asthma and allergic disease risk. Adverse exposures in this critical developmental window may have a marked and prolonged effect on health. A birth cohort of high-allergy risk children will be used to investigate the effect of common chemical exposures on the risk of asthma and allergic disease up to 25 years. This evidence could be used to inform guidelines on common household chemical exposures
I am a perinatal physiologist who specializes in determining the factors that cause fetal and neonatal brain damage, and in devising treatments to prevent this for application in pregnant women and the neonate.
A Risk Stratification Tool For The Prevention Of Avoidable Perinatal Mortality And Morbidity

Summary
Stillbirth is more common in Australia than in some high-income countries. Babies born early may experience lung or other problems. Many current stillbirths and preterm birth can be prevented. Using a cohort of >4.5 million births from WA, NSW, SA and NT (N >4.5 million), this project will develop a strategy to predict the risk of stillbirth, preterm birth, and low birth weight. Better identification of risk in pregnancy will improve antenatal care to reduce stillbirth and neonatal morbidi ....Stillbirth is more common in Australia than in some high-income countries.

Identifying Mechanisms Underlying Ethnic Inequalities In Birth Outcomes

Summary
There are significant ethnic inequalities in birth outcomes in Australia however the mechanisms underlying the relationships are unclear. This is important to investigate if improvements in outcomes for all women and babies are to be achieved. This study will identify potential mechanisms underlying the ethnic inequalities in Victoria. This work will inform clinical practice guidelines with the goal of improving health outcomes for women and their babies from different ethnic groups.
