Sleep Health And Sleep Problems In Early Childhood: What Role Does Childcare Play?

Summary
Sleep is significant for young children’s health and development and impacts on family functioning. Increasingly childcare is part of the young child’s sleep environment. This study focuses on the role of childcare in supporting sleep health and identifying sleep, and associated behavioural problems, in the early years of life. The study responds to the policy, practice and legislative demand for evidence to guide appropriate provision for sleep and rest in the childcare context.

Summary
Infant sleep problems and postnatal depression are common in the Australian community. Over a third of Australians report a problem with their infant's sleep in the second six months of life whilst 10-15% of Australian women will experience an episode of depression in the first year after their child is born. Both infant sleep problems and postnatal depression have been associated with serious outcomes including child abuse, child behaviour problems, maternal physical and emotional problems, fam ....Infant sleep problems and postnatal depression are common in the Australian community. Over a third of Australians report a problem with their infant's sleep in the second six months of life whilst 10-15% of Australian women will experience an episode of depression in the first year after their child is born. Both infant sleep problems and postnatal depression have been associated with serious outcomes including child abuse, child behaviour problems, maternal physical and emotional problems, family stress and family breakdown. This study builds on previous work conducted by researchers at the Centre for Community Child Health, Royal Children's Hospital, Melbourne. In this work, a brief behavioural intervention significantly decreased infant sleep problems and symptoms of maternal depression, particularly for depressed mothers. The intervention consisted of controlled crying and removal of sleep associations such as a dummy which the infant had become dependent upon to fall asleep. Mothers who received the intervention reported 20% fewer sleep problems and a 45% reduction in depression symptoms compared with mothers who did not receive the intervention. The interention also improved maternal sleep quality and quantity and reduced the need for professional sleep services. It was acceptable to mothers, of low cost and was minimally disruptive to families - in contrast to many current strategies directed primarily at postnatal depression. This trial aims to determine whther a similar intervention delivered by Victorian Maternal and Child health nurses within their usual practice settings can replicate these important benefits.Read moreRead less
It’s The Amount That Counts: The Impact Of Seven Days Of Sleep Restriction On Predictors Of Type 2 Diabetes.

Summary
The aim of this project is to examine the relationship between sleep duration (5, 6, 7, 8, or 9h per day for one week) and glucose metabolism. This will allow us to quantify the amount of harm that different levels of sleep loss cause to the physiological systems that protect people from developing serious health disorders. In particular, the results of the project will be invaluable in the design of effective behavioural interventions for the prevention and/or treatment of type 2 diabetes.
DEEP LEARNING AND PHYSIOLOGY BASED APPROACH TO DERIVE AND LINK OBSTRUCTIVE SLEEP APNOEA PHENOTYPES AND SYMPTOMATOLOGY

Summary
Obstructive sleep apnoea (OSA) is a highly prevalent nocturnal breathing disorder strongly related to daytime sleepiness, accident risk and reduced quality of life. However, the current severity index, the apnoea-hypopnoea index, poorly predicts daytime sleepiness and vigilance. In this project we elegantly combine physiological insight and artificial intelligence to develop and evaluate novel clinically applicable computational tools for detailed quantification of OSA severity and its symptoms.
Towards direct imaging of neuronal currents with MRI. This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity.

This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity. Signal-to-noise ratio is at the limits of detectability using current imaging systems and nc-MRI is yet to be convincingly demonstrated. An integrated framework for simulating nc-MRI in the visual cortex is expected to be developed.Read moreRead less
The role of synapse development in cognitive disorder. In humans, intellectual disability occurs when nerve cells in the brain fail to connect. The project examines fundamental molecular processes involved in synapse development of neurons. The use of insect models provides a generalised biological template to understand how synaptic molecules contribute to behaviours that underlie cognitive disorder.
Control of cellular differentiation in the developing brain. This project aims to understand how mature brain cells form during foetal life.

This project aims to understand how mature brain cells form during foetal life. The central hypothesis is that a specific transcription factor family, called NFI, regulates the epigenetic state of the cell, allowing chromatin accessibility and subsequent transcriptional activation and repression to control cellular differentiation. Aims 1 and 2 will investigate how brain cells transition from proliferating progenitor cells to differentiated mature cell types. Aim 3 will investigate how differentiation is maintained in the adult brain. Methods used involve genome and chromatin analyses of cells isolated from transgenic mouse models. Outcomes and benefits are substantial knowledge gain applicable to stem cell regulation and brain health.Read moreRead less
Improving School Transition By Improving Child Sleep: A Translational Randomised Trial

Summary
A successful transition to school sets a child on a path for life. A poor transition can lead to early drop out, poor peer relationships and poor emotional skills. In 2008/09, we found that a brief sleep intervention for children improved key determinants of a successful transition including social-emotional functioning and parent mental health. We now plan to see if the same intervention, delivered by school nurses, can have a similar effect.
Transcriptional control of neural stem cell differentiation during development and disease. Understanding the molecular mechanisms that control how neural stem cells differentiate is critical to provide potential therapeutic treatment for neurodegenerative diseases and for brain cancer. This project will aim to discover, using an animal model system, the genes and molecules regulating these key biological processes.
