Acute Traumatic Coagulopathy- Mechanisms And Measurement
Funder

Funding Amount
$188,226.00
Summary
Acute traumatic coagulopathy (ATC) refers to impaired blood clotting post major trauma and is associated with high, early mortality. Inability to predict this disorder and poor knowledge regarding its detailed biochemical mechanism has hindered development of evidence based guidelines to manage patients with ATC. This project aims to correlate early biochemical disorders with clinical management and outcomes post trauma to determine mechanisms leading to ATC and determine management strategies.
A Randomised Controlled Trial Of Factor Replacement Therapy In Snake Bite Coagulopathy
Funder
National Health and Medical Research Council
Funding Amount
$715,730.00
Summary
This proposal seeks funding to undertake a controlled trial of clotting factor replacement in snake bite coagulopathy after the administration of a neutralising dose of antivenom. The aim is to determine if factor replacement will result in a rapid return of clotting function in patients and therefore reduce the potential risk of major bleeding. This study will have international implications because globally snakebite coagulopathy is a major cause of morbidity and death like in Australia.
Structural And Functional Studies On The Interaction Between Alpha2-Antiplasmin And Plasmin
Funder

Funding Amount
$280,400.00
Summary
Fibrinolysis is the process by which the body dissolves clots. In this proposal we aim to investigate how the fibrinolysis inhibitor alpha2-antiplasmin interacts with the clot dissolving protease enzyme plasmin. These data will be useful for developing new approaches to accelerate plasmin-mediated clot breakdown.
Improving Health Outcomes In Drug Overdose And Envenoming: Risk Assessment And Interventional Studies

Summary
The research aims to improve our understanding of the mechanisms and treatments for poisoning and envenoming. Observational studies measuring toxin levels will be done to investigate the effects of drug overdose and terrestrial and marine envenoming. Clinical trials will be done to investigate the benefit and safety of antivenom in snake/spider envenoming, antidotes and other treatments for drug overdose, including decontamination such as activated charcoal.

The Role Of Tissue Factor In The Regulation Of Extracellular Matrix Remodelling And Angiogenesis.

Summary
The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal me ....The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal menstrual cycle, and for the normal growth and development of the placenta and a new baby. The processes by which these new blood vessels form and the factors contributing to the maintenance of their structure are incompletely understood. However, it is known that the interaction of cells and the surrounding extracellular matrix is critical for normal cell function and in particular for new blood vessel formation. Studies in this project will seek to define a relationship between some of the factors which regulate blood clotting, and those that regulate turnover of the extracellular matrix and new blood vessel formation. In particular, how blood clotting factors may be invovled in the regulation of the extracellular matrix will be studied in a rapidly developing tissue, the mouse placenta. The role of blood clotting factors in regulation of new blood vessel formation into an artificial avascular tissue will also be examined. These studies will employ some of the new genetic techniques to understand new roles for proteins which have been traditionally thought to act in only one way. This research has the potential to provide new insights into how blood vessels are formed and are subsequently maintained. This increased understanding will provide the knowledge required for the development of new therapeutic strategies to correct the process when it goes wrong, is unwanted or underdeveloped in human disease.Read moreRead less
Factor XII Dependent Coagulation, Thrombin And Platelet Glycoprotein 1ba In Arterial Thrombosis And Bleeding Disorders
Funder
National Health and Medical Research Council
Funding Amount
$104,664.00
Summary
Clot formation is the key event underlying heart attacks and strokes. There is new data that Factor XII (FXII) can play an important role in clot formation-thrombosis. We aim to examine the role FXII plays in clot formation, in particular the role of FXII in thrombin generation, which is the central event of clot formation, and its interaction with platelet glycoprotein 1ba (another important molecule in thrombosis). New insights into clotting and new therapies can result from our research.
Does Fresh Frozen Plasma In Russells Viper Bite Coagulopathy Reduce The Dose And Duration Of Antivenom Therapy?

Funding Amount
$622,344.00
Summary
This proposal seeks funding to undertake a trial of clotting factor replacement with low dose antivenom therapy in snake bite coagulopathy in Sri Lanka. The aim is to determine if factor replacement will result in a rapid return of clotting function, allow a smaller dose of antivenom and therefore reduce the potential risk of major bleeding and reactions to antivenom. This study will have international implications because globally snakebite coagulopathy is a major cause of morbidity and death .

Safety And Quality Of Life Of Peri-operative Transdermal Estradiol Continuation During Gender Affirmation Surgery In Transgender Women: A Randomised Placebo-controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$92,335.00
Summary
Despite no clear evidence, transgender women are told to stop their feminising estrogen treatment several weeks before gender surgery, but this causes severe 'menopausal symptoms' with hot flushes, depression and distress compounding an already stressful preparation for and recovery from major surgery. This trial will establish if continuing estrogen gel around the time of surgery is safe and effective at improving 'menopausal symptoms'.
