This project aims to study pre and postnatal childhood factors and examine their association with HPA-functioning, cognition, and mental health during adolescence in the Western Australian Pregnancy Cohort Study (Raine Study).

Childhood exposures include not only trajectories of stressful life events, family functioning and mental health status during childhood, but also effects of intrauterine and postnatal growth patterns, and a comprehensive range of psychosocial, familial and environmental factors. It is our objective to characterise functional polymorphisms for genes related to stress regulation and examine their interactions with early life exposures and their neurobiological consequences. We will also test 16 year old Raine subjects for cognitive ability, and in some we will image their brain activity while performing these tests. We anticipate to enhance the already comprehensive phenotypic Raine Study data base with neurobiological information for future neuroscience studies as the Raine cohort matures. We hypothesise that increased and sustained trajectories of early life stress, family dysfunction or poor mental health during childhood will increase the risk of Raine Study adolescents experiencing: (i) - increased stress sensitivity with higher baseline cortisol levels during adolescence; (ii) - increased adolescent stress sensitivity, if they are carriers of specific haplotypes of the glucocorticoid and mineralocorticoid receptor genes.;(iii) - depression during adolescence, if they are homozygous or heterozygous for the short allele of the serotonin transporter (5-HTT) gene; (iv) - poorer cognitive performance and increased atypical non-prefrontal cortex (PFC) brain activity during cognitive testing as measured by fMRI; and (v) -more mental health problems during adolescence.Read moreRead less
Extended Follow Up Of The RENAL Study And Individual Patient Data Meta-analysis In Acute Kidney Injury

Summary
Acute kidney failure is increasingly common and associated with very high mortality. The long term consequences for patients and their kidney function are unknown. By extending follow up of the RENAL study, which explored how the dose of dialysis affected survival, and combining it with other trials from around the world, we will provide the strongest evidence regarding how dialysis treatment can reduce this mortality and define the long term consequences of this condition.

The aim of this body of work is to improve understanding of the incidence and outcomes of chronic kidney disease for Indigenous Australians, in order to try to better predict outcomes and guide clinical and policy-level decision making.
What Are The Clinical Predictors And Risk Factors For Impaired Child Growth And Development? Following Up The Ha Nam Cohort From Birth To 3 Years
Funder

Funding Amount
$1,189,570.00
Summary
Stunting affects about one third of children under five in developing countries and is a measure of chronic undernutrition. This project will identify pre and postnatal risk factors for impaired child growth and development by monitoring a cohort of infants in Vietnam to three years of age, and developing a predictive algorithm for early detection of those at risk of stunting. Effective preventative measures would improve child health, and prevent a huge burden of disease.
