Summary
Chronic suppurative (ie infected) lung diseases in children are major causes of poor health and deaths worldwide. Repeated childhood infections contribute to poor lung health in adults. The most common organism causing infection is non-typeable Haemophilus influenzae (NTHi). This study aims to determine whether a vaccine against NTHi can reduce repeated respiratory infections in children.

Summary
The survival rate for tiny or very premature babies has improved dramatically in recent times, from below 10% in the 1960s to greater than 70% in the 1990s. However, some of these babies require prolonged periods of help with breathing and oxygen treatment to survive, and many develop a form of chronic lung disease in the newborn period.

However, some of these babies require prolonged periods of help with breathing and oxygen treatment to survive, and many develop a form of chronic lung disease in the newborn period. A powerful group of drugs, known as corticosteroids, have been used to treat or prevent this chronic lung disease in newborn babies, with some success in shortening the time that the babies need help with breathing. However, corticosteroids have the potential to cause long-term harm to the developing baby's brain, and may cause lifelong problems with thinking, walking, talking, seeing or hearing. We want to test in a clinical trial if corticosteroids, specifically dexamethasone, can reduce the need for help with breathing and the rate of chronic lung disease without causing long-term problems to the developing baby's brain. Babies who are very tiny (born weighing less than 1000 g), or born very early (born before 28 weeks of pregnancy, or more than 12 weeks premature) will be eligible for this study if they still need help with their breathing after one week of age from a machine called a respirator, and their doctor considers that corticosteroids might be helpful to the baby's breathing. Some babies will receive dexamethasone and other babies will be treated with a harmless placebo - chance will decide which treatment the baby receives. All other aspects of the babies' care will continue as normally. Children who survive to 2 years of age will be assessed fully to determine if they have any problems with their health, including problems with their thinking, walking, talking, seeing or hearing. We will determine if dexamethasone is helpful or not for very tiny or very premature babies who have breathing problems after the first week of life. We will also measure the economic impact of dexamethasone treatment in these babies.Read moreRead less

Summary
The survival rate for tiny or very premature babies has improved dramatically in recent times, from below 10% in the 1960s to greater than 70% in the 1990s. Several new treatments have helped to improve their survival rate, but some have the potential to cause long-term harm to the developing baby's brain or lung, and may cause lifelong problems with thinking, walking, talking, seeing, hearing, growth or breathing.

Several new treatments have helped to improve their survival rate, but some have the potential to cause long-term harm to the developing baby's brain or lung, and may cause lifelong problems with thinking, walking, talking, seeing, hearing, growth or breathing. Babies who are very tiny (born weighing less than 1000 g), or born very early (born before 28 weeks of pregnancy, or more than 12 weeks premature) will be assessed long term (to 8-9 years of age), as broadly as possible, and in comparison with normal birthweight (NBW, birthweight >2499 g) children. Outcomes will encompass academic progress and behaviour, brain function, general health, growth, and respiratory health. We will compare the outcomes for very tiny-preterm children who were treated with several of these new therapies with those who were not so treated. We will assess whether alternative measures of long term outcome that assess the quality of life are applicable to very tiny-preterm children. If so, these measures could be used much more widely, since they are cheaper and less time-consuming.Read moreRead less
Respiratory failure at birth is a major cause of death and disease in newborn infants. At birth the airways must be cleared of liquid to allow the inhalation of air, but, little is known about the process of lung aeration, because it has not been possible to observe or measure it. We have developed imaging and analytical techniques to observed and measure lung aeration. We will determine ventilation procedures that promote uniform lung aeration and minimise lung injury in ventilated infants.
I am a neonatologist interested in improving the outcomes of graduates of neonatal intensive care units. Currently the focus of my research is stabilisation immediately following birth and my research portfolio ranges from bench-top and animal studies thr
Nasal CPAP For Very Preterm Infants At Birth: Does It Improve Outcome? A Randomised Controlled Trial

Summary
Neonatal respiratory distress syndrome (RDS) is the major cause of morbidity and mortality in preterm infants. Many of these infants need ventilatory support to keep them alive. In 1996 and 1997, 10,471 infants in Australia and New Zealand needed ventilatory support for a total of 72,544 days. This treatment is a great physical burden for the infants and an enormous emotional stress for their parents.

Many of these infants need ventilatory support to keep them alive. In 1996 and 1997, 10,471 infants in Australia and New Zealand needed ventilatory support for a total of 72,544 days. This treatment is a great physical burden for the infants and an enormous emotional stress for their parents. Each day of treatment costs about A$2000 so their hospital treatment costs about $72 million a year. Of infants born less than 29 weeks' gestational age, about 40% of the survivors subsequently developed chronic lung disease (CLD). This condition is defined as prolonged dependence on supplementary oxygen therapy. CLD is associated with further costs and increased lung problems and readmissions to hospital in the first year of life. Thus, CLD is an expensive and time-consuming condition that has a high social cost. This project will determine whether treating these very premature babies from birth simply by applying oxygen under a low continuous positive pressure (CPAP) into their nose rather than the present treatment of placing a tube in the windpipe (known as intubation) and ventilation will reduce the incidence and severity of neonatal respiratory distress syndrome and subsequent chronic lung disease. The project will involve 600 babies from different, high quality neonatal intensive care units. Babies who are born at less than 29 weeks' gestation and who show signs of breathing at birth will be randomly allocated to be treated with either nasal CPAP or intubation and ventilation. This project will determine whether CPAP treatment at birth improves survival and reduces the severity of the RDS and subsequent CLD, or has no long term beneficial effect. If the trial is successful, this will be one of the most useful new treatments in neonatal medicine because it is simple to use, easier for the babies, and cheaper than ventilation.Read moreRead less
