Understanding The Regulation Of HERG Potassium Channel In The Myometrium At The Time Of Labour

Funding Amount
$597,661.00
Summary
We have shown that a potassium channel known as hERG falls precipitously at the time of term labour and that blocking this channel causes powerful uterine contractions. This grant will determine how the expression of this channel is regulated in the myometrium and whether changes in hERG channels also occur in premature labour.
Understanding The Myometrial Transition At Term And Preterm Labour To Guide Tocolysis

Summary
This grant seeks to understand how the muscle cells of the uterus transform at the time of labour. We propose that this transformation is organised by enzymes that modify the histones around key genes. We will test if a similar pathway operates in cases of preterm labour. The results will guide the development of new ways of treating premature labour that will use targeted nanoparticles to deliver siRNA directly to the muscle cells of the uterus.
A Double Blind Randomised Placebo Controlled Trial Of Melatonin As An Adjuvant Agent In Induction Of Labour

Summary
Induction of labour, a common obstetric intervention fails in almost 40% of first time mothers. There is evidence to suggest that the endogenous hormone melatonin has important roles in the progress of labour. We will undertake a double-blind randomised placebo controlled trial of melatonin supplementation to improve the success of induction of labour in first time mothers. We will also assess the economic impact of melatonin supplementation at induction of labour.
Premature babies often need assistance to breathe but this can injure the lung and lead to abnormal lung development and long-term lung disease. We have recently identified 3 factors that we believe are fundamental to initiating this abnormal lung development. We will demonstrate that these 3 factors mediate abnormal lung development following lung injury at birth. This information can then be used to reduce the incidence and severity of chronic lung disease of the newborn.
Impact Of Extreme Prematurity Or Extreme Low Birthweight On Young Adult Health And Well-Being: The Victorian Infant Collaborative Study (VICS) 1991-92 Longitudinal Cohort

Summary
Significant advances in medical care have increased survival of the tiniest and most premature babies. Those who have benefited from modern medicine are now in their mid-20s. We know they have more problems in childhood and adolescence compared with those born full term. However, we know little about their health problems in adulthood. This study will inform us of adult health problems in this vulnerable group and provide vital information about the best care for this increasing group of adults.
Treatment Of Asymptomatic Candidiasis In Pregnant Women For The Prevention Of Preterm Birth: A Randomised Trial

Funding Amount
$1,120,373.00
Summary
Being born too early is a leading cause of perinatal death and morbidity. This trial seeks to determine whether screening for and treating candidiasis in pregnancy reduces the risk of this serious health problem. The trial will discover whether a simple treatment in pregnancy can reduce preterm birth. If positive, the results will be relevant to the management of every pregnancy.
Failure-to-progress In Human Labour Results From A Profound Electrical Negativity Of The Uterine Cells: Targeting The Ion Channels Involved

Funding Amount

Summary
The incidence of failure to progress in labour has increased in recent years, being linked to the rise in obesity. The result is a significant escalation in the rate of delivery by Caesarean Section (CS) which increases the risk of serious complications during subsequent pregnancies. We have identified dysfunctional systems associated with poor uterine contraction. We now aim to determine the mechanisms underlying these dysfunctional systems to lay the foundations for better therapeutics.
Second Trimester Intra-amniotic Treatment For Early Preterm Birth

Funding Amount

Summary
Preterm birth is the leading cause of neonatal death and disability in Australia today, with those born before 32 weeks' completed gestation at the highest risk. Preventing these early preterm births requires treatment of the causative uterine infection. This proposal is to conduct the first study of direct intraamniotic antibiotic treatment of uterine Ureaplasma infection in a clinically relevant, large animal model of second trimester pregnancy.
The aim of this project is to determine whether or not turning a baby from the posterior position to the more common anterior position increases the chances of a normal birth. This involves performing an internal examination during labour and gently turning the baby as the mother pushes. At present, if the baby is in the posterior position (facing towards the front of the mother’s body) there is a higher risk of a caesarean, forceps or vacuum delivery.
Impact On Caesarean Rates Following Injections Of Sterile Water (ICARIS) – A Randomised Controlled Trial.

Summary
The rising number of caesarean section births is causing concern across the country. Injections of small amounts of sterile water into the lower back provide relief to women who have back pain in labour. A review of the research found that administration of these injections may be associated with a reduction in caesarean section rates. Four Queensland hospitals, will conduct the largest study to date to determine if sterile water injections can decrease caesarean section rates without increasing ....The rising number of caesarean section births is causing concern across the country.
