Summary
In many countries, oxycodone is replacing morphine as the opioid of first choice for the treatment of moderate to severe pain. Despite this, very little is known about how the drug is processed in the body or how its ability to control pain is affected by such factors as other drugs, age or organ function. Studies to determine this usually require multiple blood tests from individual patients over set time periods. Our team is able to measure drug levels in saliva and has shown this to be a vali ....In many countries, oxycodone is replacing morphine as the opioid of first choice for the treatment of moderate to severe pain. Despite this, very little is known about how the drug is processed in the body or how its ability to control pain is affected by such factors as other drugs, age or organ function. Studies to determine this usually require multiple blood tests from individual patients over set time periods. Our team is able to measure drug levels in saliva and has shown this to be a valid substitute for the measurement of drug levels in blood. Furthermore, one of us has developed a computer modelling system that shows how drugs are handled in the body using only a few samples from each patient. Palliative care patients are generally frail and unwell. We are reluctant to expose them to invasive tests such as repeated blood sampling. If we can prove that saliva sampling is as good as blood sampling, we will have identified a simple non-invasive means of greatly increasing our knowledge of oxycodone and how it behaves in individual patients. This in turn may allow us to tailor drug doses according to the unique characteristics of each patient and to optimise their pain control.Read moreRead less
Chronic Oral Graft-versus-host Disease: Clinical Risk Factors, Biochemical Markers Of Disease Activity And Novel Therapeutics

Summary
Chronic graft-versus-host disease (GVHD) is a serious complication of bone marrow transplantation. The oral cavity is often affected. Aims: 1.Identify and validate risk factors for oral GVHD 2.Assess if specific salivary components reflect disease activity 3.Trial novel therapeutic for GVHD-associated dry mouth Saliva testing may offer a non-invasive method to monitor oral GVHD. Also, new and effective topical agents are greatly needed and will improve therapeutic options in oral GVHD
Understanding Relapse In Posttraumatic Stress Disorder: An Investigation Of Return Of Fear.

Summary
Posttraumatic Stress Disorder (PTSD) is common and results in significant impairment. There are effective psychological treatments for PTSD, yet relapse following treatment remains high. The proposed research will involve a series of experiments and observational studies to better understand the process that lead to relapse in patients receiving treatment for PTSD. The findings of these studies will assist in modifying treatment to ensure that symptom gains are maintained following treatment.
T Helper Cytokines In Immunity And Organ-specific Autoimmunity

Summary
The overall goal of these studies is to identify mechanisms underlying the effects of cytokines on T cell-mediated immunity, how defects in these processes can result in organ specific autoimmune disease, and whether exploiting these mechanisms may result in improved therapies for individuals with autoimmune diseases. The proposed aims build on my previous work on interleukin-21 and interleukin-21-producing T helper cells in both immunity and autoimmunity.
