Perinatal Stress Leads To Neurosteroid Deficits And Adverse Behavioural Outcomes

Funding Amount
$1,198,042.00
Summary
This grant will examine the effect of psychosocial stress experienced after birth on the production and regulation of steroid hormones in the brain of newborn animals. The work will investigate how stress changes the levels these brain steroids and sensitivity to them and if these effects are remain into adulthood. The studies will then determine if these changes lead to adolescent behaviour disorders. The effectiveness of steroid therapies in treating these disorders will also be determined.

Summary
Problems around birth are common and can have long-term implications, including into adulthood. Our goal is to improve health outcomes for all newborn babies and their families by determining factors that enhance outcome and assessing the benefits and consequences of new treatments for mothers and babies. We are world leaders in this field and are dedicated to training the next generation of health professionals in the care of newborn babies, in Australia and the rest of the world.
Does Caffeine Affect The Development Of The Very Immature Brain: Dose Response Relationship?

Funding Amount
$668,386.00
Summary
Premature birth is a major health problem worldwide. Preterm babies often develop apnoea of prematurity (AOP), which is commonly treated with caffeine. Trials indicate that preterm babies treated with low dose caffeine have less neurodevelopmental disabilities at 18 months. Higher doses of caffeine are often needed to reduce AOP but the risk of this is unknown. We will study the short and long-term effects of increasing doses of caffeine on the developing brain in a long-gestation species.
Mechanisms Of Escape From Progesterone-induced Suppression: Role In Normal And Preterm Birth

Funding Amount

Summary
Prematurity caused by preterm birth is the leading cause of death and disease among newborns in Australia. Here we will define how the length of pregnancy is determined by the opposing actions of progesterone, which maintains pregnancy, and prostaglandins, which induce labour. We will demonstrate the mechanism by which the actions of the two hormones are balanced in normal pregnancy and disrupted in preterm labour. We will show that preterm birth can be prevented by correcting the disorder.
