Towards early detection of upper airway obstruction in children: investigation of autonomic control. This project focuses on the investigation of new indicators for early detection of upper airway obstruction (UAO)-which is a common sleep disorder in children. Failure to treat UAO can result in serious adverse outcomes including failure to thrive, neurocognitive deficits, developmental delay, behavioural disorders and cardiovascular disease. Thus, early treatment of UAO will significantly improv ....Towards early detection of upper airway obstruction in children: investigation of autonomic control. This project focuses on the investigation of new indicators for early detection of upper airway obstruction (UAO)-which is a common sleep disorder in children. Failure to treat UAO can result in serious adverse outcomes including failure to thrive, neurocognitive deficits, developmental delay, behavioural disorders and cardiovascular disease. Thus, early treatment of UAO will significantly improve quality of life for the child. Direct benefits to community health via reduced costs for medical treatment will also be a key outcome. The establishment of new diagnostic indicators will form the basis of new tools for identifying child sleep disorders and contribute to advancing Australia's international leading position in health technology.

Summary
Many diseases that effect the respiratory system have their primary effect on the lungs and airway themselves but in some conditions, such as obstructive sleep apnea (OSA) and asthma, increased breathing load can induce periods of low blood oxygen which could further contribute to morbidity in these diseases.

OSA is a disorder associated with snoring. Patients experience periods of sleep fragmentation and oxygen deprivation due to obstruction of the floppy portion of the upper airway (pharynx) during sleep. It affects 4% of men and 2% of women and causes excessive daytime sleepiness leading to increased risk of accidents, high blood pressure and premature cardiovascular disease. Asthma produces airway inflamation and narrowing and affects a wide range of people. Both OSA and asthma are associated with episodes of impaired breathing and reduced levels of oxygen in the blood. Low levels of oxygen in the blood (hypoxia) is well known to impair functioning of the central nervous system. We have recently found that hypoxia blunts sensations of increased breathing load in healthy people and in asthmatics. Hypoxia might therefore contribute to worsening of attacks in these diseases. This study aims to investigate how changes in blood oxygen levels affect brain processing of respiratory signals, how this translates to perception of sensations and the physiological adaptations that people make to cope with increased breathing load. We will also investigate whether the inhibitory effects of hypoxia on central nervous system function extend to other vital protective respiratory reflexes such as cough, awakening from sleep to increased breathing load and upper airway reflexes that are important for maintaining an open airway.Read moreRead less

Summary
This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking).

Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example, asthma affects 12% of adults and amongst these, 15% waken weekly or more often with their asthma while 6% are hospitalized annually. There is a need to understand the basic mechanisms underlying these diseases so that new strategies can be developed to modify bronchocondtriction and inflammation. The project will provide new knowledge concerning the physiology of Zn in the respiratory epithelium and interactions between Zn deficiency and oxidants on injury in the respiratory tract. The usefulness of easily accessible nasal epithelial cells as a measure of Zn and Zn transporter levels deeper in the respiratory tract will be assessed. The project encompasses a number of fields and utilizes in vitro cellular and animal models, as well as tissues from human subjects.Read moreRead less
Childhood obesity, physical activity and wellbeing: Discovering the influence of children's understandings and experiences of places, spaces and communities. The study aims to discover 3-13 yr old children's understandings, perceptions & experiences of physical activity & associated places & spaces. Childhood obesity is a modern 'epidemic' & governments agree that low physical activity levels contribute significantly.

The study aims to discover 3-13 yr old children's understandings, perceptions & experiences of physical activity & associated places & spaces. Childhood obesity is a modern 'epidemic' & governments agree that low physical activity levels contribute significantly. Epidemiological & clinical research has been undertaken, but we lack Australian studies that systematically listen to & understand the pivotal voices of children themselves. Failure to develop such theoretically sound, practice-based understandings may mean ineffective interventions that misunderstand children's worlds. This collaborative study unites highly experienced researchers, practitioners & policy makers who will actively involve children in creating & using new knowledge.Read moreRead less

Intimate partner abuse (IPA) is estimated to affect one in four women at some stage in their lives, and to impact on the lives of at least one million Australian children annually. This study will investigate the extent to which exposure to intimate partner abuse during pregnancy and in the first 12 months postpartum predicts child outcomes in middle childhood.

Funding Amount
$283,934.00
Summary
Children’s healthy development is important for their readiness to learn, academic achievement at school, and for their future health and economic capability. This study links whole-of-population administrative data from nine different government sources, and data collected as part of a natural experiment evaluating the effects of the South Australian Family Home Visiting program to inform policy and service delivery in child health and development in South Australia.
The Kids in Communities Study: national investigation of community level effects on children's developmental outcomes. This project (a cross-disciplinary collaboration) will investigate community level factors influencing early childhood developmental outcomes using a mixed methods approach in up to 10 communities across Australia. This will result in a potential set of measures or indicators that reflect communities that are good for children.
Healing The Past By Nurturing The Future: Learning How To Identify And Support Indigenous Parents Who Have Experienced Complex Childhood Trauma

Summary
Complex childhood trauma causes profound and long-lasting effects on physical, social and emotional wellbeing, which can be triggered during the transition to parenthood and impede the capacity of parents to nurture their children. The transition offers a unique opportunity for healing and preventing intergenerational transmission of trauma. This project co-designs and evaluates acceptability and feasibility of screening and support for Indigenous parents experiencing complex trauma.
Airway Epithelial IAPs And Their Interaction With Zn Ions

Funding Amount
$260,779.00
Summary
The air we breathe contains a variety of harmful substances. Damage to the lining involves death of the ciliated cells that line the airways. We have shown that zinc protects these cells from premature death. This application focuses on a family of proteins called IAPs which bind zinc and regulate cell death in other tissues. This project focusses on how the IAPs and Zn may act together to mainitain healthy airways and how abnormalities of these may occur in people with asthma.

Funding Amount
$1,075,842.00
Summary
Children exposed to social adversity, family violence and trauma have higher risks of emotional, developmental and physical health problems. Despite this, many children experiencing social adversity and trauma grow up with positive outcomes. This will be the first international study of resilience in middle childhood. The study will examine factors promoting resilience in Aboriginal children, children exposed to family violence and children in families of refugee background.
