Summary
Our previous work indicates that evoked human blood borne factors confer protection against injury, due to loss of blood flow in heart muscle, when a brief stress is remotely applied to a limb (remote ischemic preconditioning). We have identified these proteins that appear to activate genetic and metabolic regulation of adaptive cell survival processes. We will now test their individual and combined capacity, efficiency and mechanisms of protection in the heart using cell and clinical models.
Outcomes Of The Arterial Switch Operation: A Multi-centre Study

Summary
The arterial switch operation is the surgery of choice for children born with transposition of the great arteries, a congenital heart defect where the main two vessels of the heart arise from wrong pumping chambers of the heart. There are very few studies looking at adults after this operation. We aim to study all patients who have had an arterial switch. The results of this study will further increase our knowledge of the long term consequences of having the arterial switch operation.
Childhood Lymphatic Malformations: The Mechanism Of Rapamycin In Controlling Growth

Summary
Lymphatic malformations (also known as cystic hygromas or lymphangiomas) cause deformity and pain which can last lifelong. Current treatments help but do not fix all the symptoms. Rapamycin, a drug used for many years in children and adults with kidney transplants, may be useful for treating children with lymphatic malformations. We aim to understand how the drug works on the cells of lymphatic malformations in culture and in an animal model, to develop new and more effective treatments.

Summary
The effectiveness of intervention in communication and safety climate in the operating room. This project will evaluate the effectiveness of an educational intervention on teamwork behaviours in surgery. It will deliver beneficial effects for communication in service delivery, safety and patient care in support of health care in high risk environments.
Acute pancreatitis is an acute abdominal inflammatory process (the pancreas attempts to digest itself) with significant mortality in those patients having the severe form of the disease. The commonest causes of the disease are gallstones and excessive alcohol consumption. Approximately 80% of patients with acute pancreatitis recover, but 20% experience the severe form of the disease. In severe pancreatitis, 30% of patients die.

The commonest causes of the disease are gallstones and excessive alcohol consumption. Approximately 80% of patients with acute pancreatitis recover, but 20% experience the severe form of the disease. In severe pancreatitis, 30% of patients die. Severe pancreatitis is associated with necrosis (cell death) of the pancreas which, results from reduced blood flow in the organ. This reduced blood flow may be secondary to increased pressure in the pancreatic duct following occlusion of the duct. Preliminary studies suggest that the reason why the pancreas may be susceptible to necrosis is the anatomical arrangement of its blood supply, being made up of many end arterioles (very small arteries) that do not connect with other arteries. The consequence of this arrangement is that if a particular end arteriole becomes blocked, the area of the tissue cannot obtain a blood supply from neighbouring arterioles (as in other organs). Blood supply is partly controlled by nerves. The nerve transmitter nitric oxide is one of the major chemicals involved in this regulation. Nitric oxide also regulates the pressure in the pancreatic duct by acting on the sphincter of Oddi, situated at the opening of the pancreatic duct. Consequently, the action of nitric oxide during pancreatitis may be crucial to the development of the severe disease. This proposal seeks to define the blood supply of the pancreas, its regulation, the effect that increased pancreatic duct pressure has on it and the role that nitric oxide plays in this. If the hypotheses regarding the role of nitric oxide on pancreatic blood flow is proven, then drugs which influence nitric oxide levels can be used to limit the production of pancreatic necrosis. In turn, such an effect will reduce the mortality and morbidity of acute pancreatitis.Read moreRead less
Examining healthcare professionals' communication across the surgical pathway to improve patient safety. Recent data show breakdowns in communication contributed to 16% of sentinel events in Australia, the majority of which were of a surgical nature. Financial costs associated with adverse events are enormous, estimated at around $A2billion/year. Economic burden is predicted to increase with further complexities surrounding patients' surgical care.

Recent data show breakdowns in communication contributed to 16% of sentinel events in Australia, the majority of which were of a surgical nature. Financial costs associated with adverse events are enormous, estimated at around $A2billion/year. Economic burden is predicted to increase with further complexities surrounding patients' surgical care. This study will result in new knowledge about communication patterns to inform the development of reporting methods and strategies that positively influence the practices of healthcare professionals. Strategies could be extrapolated to the broader healthcare sector, and provide tactical direction aimed at averting clinical errors, preventing patient harm and reducing healthcare costs.Read moreRead less
