Recovery Of Left Ventricular Function After Insertion Of Left Ventricular Assist Device: Evaluation Of Echocardiographic Parameters And Longitudinal Analysis

Summary
In some patients with severe heart failure, insertion of a mechanical pump to assist the heart actually leads to recovery of the heart's function. More understanding of this process is needed so we can better predict and identify it.This project aims to assess the usefulness of ultrasound (echocardiography) in measuring heart function in patients who have a mechanical pump. Once its usefulness is established, we will use it to evaluate and attempt to induce recovery in such patients.
Prediction Of Ventricular Arrhythmias And Prevention Of Sudden Cardiac Death Following Revascularised Acute Myocardial Infarction.

Summary
Acute myocardial infarction (AMI) is a leading cause of death in Australia. Patients with coronary artery disease and impaired left ventricular function are at increased risk of heart failure, reinfarction and sudden cardiac death (SCD). This research will evaluate optimal methods to identify patients at risk for SCD following AMI using echocardiographic, MRI, and electrophysiological characteristics, and improve survival by early identification and management of these high-risk patients.
Cardiac Dysfunction In Advanced Liver Disease And After Liver Transplantation

Summary
Heart disease is the leading cause of early death after liver transplantation (LT). The scarcity of donor organs means that LT is a limited and valuable resource. We propose screening for heart disease before LT by CT scanning of heart arteries and heart function on stress testing to improve detection of coronary heart disease (CHD). Follow-up CT scans will also assess if LT causes progression of CHD. These studies will aid in development of personalised treatment strategies to improve outcomes.
Stress Hyperglycaemia And Mortality In Critical Illness: Defining The Association And Underlying Mechanisms

Summary
The relationship between high blood sugar levels (hyperglycaemia) and mortality in critically ill patients remains an area of controversy with conflicting results between studies. This PhD thesis will attempt to resolve this by firstly evaluating whether relative hyperglycaemia as measured using a novel new measure better predicts mortality outcome in such patients; and secondly, attempt to establish possible mechanisms which contributes to this.
A Dietary Intervention For Sarcopenia In Cirrhosis

Summary
Patients with chronic liver failure, or cirrhosis, suffer many complications. Sarcopenia, the loss of muscle and muscle weakness, is one of these. It is associated with reduced survival. Patients with cirrhosis have low levels of branched chain amino acids (BCAAs) which are used as building blocks for protein and energy in muscle. We aim to explore how oral supplements of BCAAs might improve muscle in this population. If this improves muscle mass, we also expect it may improve other outcomes.
Improving Microvascular Dysfunction In Falciparum Malaria

Funding Amount

Summary
Additional treatments are needed to reduce global malaria mortality. In hospitalised patients with falciparum malaria we will evaluate new methods of assessing blood vessel dysfunction in malaria. We will use these methods to conduct a trial of the safety and efficacy of sodium nitrite, a widely available drug with the potential to treat malaria by increasing nitric oxide and improving blood flow. Our results will inform the design of a larger study of sodium nitrite to treat severe malaria.
Mechanisms Of Vascular Dysfunction During Acute And Chronic Hyperglycemia

Summary
Increased consumption of sugary drinks has contributed to an epidemic of obesity and diabetes and consequently cardiovascular disease. For the first time in living memory, this may well lead to declining life-expectancy. My research will examine both the short and long-term impact of sugary drinks on vital blood vessel function. In the process it will develop better methods to monitor blood vessel function and inform public health policy on sugary drinks and preventing cardiovascular disease.
Characterisation Of MiRNAs That Regulate Vascular Leakage.

Funding Amount

Summary
Vascular permeability or leak is a major problem in diseases such as cancer and in cardiovascular diseases . MicroRNAs (miRNAs) are small control genes that influence dveleopment and disease. We have identified a miRNA cluster in endothelial cells, the cells that line the blood vessels, that is important in the control of vascular leak. This project is focused on understanding the impact of these miRNAs in disease.
Identifying Neuroimaging Based Biomarkers For Predicting Clinical Progression Along The Lewy Body Disease Spectrum

Summary
Lewy body dementias (LBD) comprise similar but heterogenous group of poorly understood disabling neurodegenerative conditions. This project aims to apply advanced neuroimaging techniques and novel psychological testing to patients at risk of Lewy body disorders as well individuals with established disease to identify novel biomarkers that may explain symptoms of these disorders as well as help predict development of LBD at its early stages when it may be amenable to neuroprotective treatments.
