I will determine the efficacy and safety of crystalloid resuscitation fluids in conventional models of care. This is a fundamental and unresolved question in Intensive Care Medicine and will have an impact on clinical practice worldwide. I will also consolidate and enhance a series of projects to provide the next generation of clinician-researchers with high-quality research opportunities. These include projects in sepsis, traumatic brain injury, and endocrine function in critical illness.
Delineating The Role Of Fludrocortisone And Hydrocortisone In The Management Of Patients With Septic Shock

Summary
Sepsis and septic shock are leading causes of morbidity and mortality globally. Steroids have been used to treat septic shock for decades. Two new trials, one using hydrocortisone vs. placebo and another using hydrocortisone plus fludrocortisone vs. placebo have produced differing results, with fludrocortisone possibly conferring a mortality benefit. My Program will investigate this evidence gap by providing critical evidence for the design and execution of a future definitive trial.
Despite advances in medical management, critical care clinicians continue to search for procedures that will improve outcomes in critically ill patients with haemorrhagic shock (a life-threatening fall in blood pressure). Shock is a consequence of an active process triggered by the brain . The proposed research aims to elucidate the precise sequence of brain events that initiate and maintain shock.

Shock is a consequence of an active process triggered by the brain . The proposed research aims to elucidate the precise sequence of brain events that initiate and maintain shock. We will also evaluate the effects of interventions (designed to ameliorate or reverse shock) on the brain events that drive the shock response. The results of this research will offer, for the first time, a rational basis for devising new methods to reverse or ameliorate shock and potentially improve clinical outcomesRead moreRead less
Sepsis is a major cause of hospitalization and ICU admission in Australia population corresponding to more than 15700 new cases each year. Every year more than 3000 people die from sepsis in Australia which is greater than the annual national road toll and breast, prostate or colorectal cancer. The research outlined in this proposal to study the effect of steroids and vitamin D to improve patient’s recovery from sepsis and also understand the genetic basis behind their ability to survive sepsis.
Counteracting Age-associated Neurodegenerative Diseases Using Chaperone-based Amyloid Disaggregases

Summary
In neurodegenerative diseases such as Alzheimer’s disease, proteins form clumps through changes in structure due to mutations or proteotoxic chemical insults. The formation of these toxic clumps causes brain cells to die prematurely triggering symptoms such as dementia. I have identified a molecular machine in human cells that efficiently clears these clumps. We are now developing strategies to activate this machine to repair damaged brain cells to slow/reserve neurodegenerative diseases.
Therapeutic Potential Of Inhibiting Eph/ephrin Signalling To Repair The Vascular Endothelium In Septic Shock

Summary
Septic shock is a life-threatening condition usually caused by bacterial infection in the bloodstream. More than 5000 people, including 500 children, die from sepsis each year in Australia. Worldwide, it is the most significant cause of death in children. Sepsis is associated with leakage of fluid and proteins through the cells lining the blood vessels. This project will develop and test a novel treatment for sepsis which focuses on reducing this leakage by blocking the Eph/ephrin proteins.

Summary
Shock is one of the most challenging clinical management scenarios experienced by clinicians. It is a syndrome characterised by an imbalance of oxygen delivery and demand particularly in vital organs. Despite the advances in current treatment strategies for patients with shock, there is still significant morbidity and mortality associated with this syndrome. It is the goal of my PhD to develop improved treatment pathways for patients with shock in order to improve their clinical outcomes.

Summary
Patients undergoing cardiac surgery often need a fluid bolus which is a volume of fluid given over a short period of time to improve their circulation. This intervention is essential as poor circulation may cause damage to important organs in the body such as the heart, lungs and kidneys. This study will allow doctors to make informed decisions about which type of fluid is better for their patients having cardiac surgery in the future.
