The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Role Of FLT PET In Malignant Pleural Mesothelioma - Prediction Of Response To Chemotherapy

Summary
Mesothelioma is a cancer of the lining of the lung. Chemotherapy is often used to treat patients in order to reduce their symptoms and to improve quality and length of life. Not all patients however benefit from chemotherapy, and most patients will experience some side-effects. Currently CT scans are used to assess response to chemotherapy, however the way that mesothelioma grows makes measuring response difficult. CT scans also are not very sensitive in detecting response early - often 3 or 4 c ....Mesothelioma is a cancer of the lining of the lung. Chemotherapy is often used to treat patients in order to reduce their symptoms and to improve quality and length of life. Not all patients however benefit from chemotherapy, and most patients will experience some side-effects. Currently CT scans are used to assess response to chemotherapy, however the way that mesothelioma grows makes measuring response difficult. CT scans also are not very sensitive in detecting response early - often 3 or 4 cycles of treatment (3-4 months) are required before benefit is seen. A test that could predict which patients were benefiting after only 1 cycle (3-4 weeks) of chemotherapy would be a great advantage, and may spare some patients unnecessary and potentially toxic treatment. Fluorothymidine (FLT) is a radioactive tracer that, after injection into a vein, is taken up by dividing cells. Tumour cells usually divide more actively than surrounding normal cells, and therefore when a positron emission tomography (PET) scan is performed it will demonstrate the tumour as a 'hot spot'. The amount of FLT uptake into the tumour depends on how much DNA synthesis (active cell division) is occurring. After chemotherapy, if the tumour responds it would be expected that the amount of FLT in the tumour will reduce. This can be assessed by repeating the FLT PET scan after the first cycle of chemotherapy. This study aims to assess the ability of the change in FLT uptake in mesothelioma after 1 cycle of chemotherapy to predict response, as measured on CT scans, and patient outcomes such as quality of life and survival. It is hoped that if successful this type of scan may improve patient care by selecting those who are likely to benefit from chemotherapy early and avoid unnecessary toxicity to patients who will not benefit from the treatment.Read moreRead less
Prospective Study Of The Emergence Of Syndromal And Sub Syndromal Anxiety And Depression During Cognitive Decline.

Summary
In older people it is well known that memory impairment and cognitive decline are associated with depression and anxiety. However, it is remains quite uncertain which comes first. For a long time it had been thought that deteriorating brain function associated with ageing and the development of dementia is also the cause of new symptoms of depression and anxiety found in older people. Recently, some evidence has emerged to challenge this hypothesis.

However, it is remains quite uncertain which comes first. For a long time it had been thought that deteriorating brain function associated with ageing and the development of dementia is also the cause of new symptoms of depression and anxiety found in older people. Recently, some evidence has emerged to challenge this hypothesis. So we plan to study this question in detail with data from an existing longitudinal study of ageing women.Read moreRead less
Discussing Prognosis & End-of-life Issues In Palliative Care: Current Practice & Dvlpmnt Of Evidence Based Trng Program

Summary
Discussing prognosis and end-of-life issues is of key importance to palliative care patients and their families. We will a) prepare evidence based communication guidelines on these topics, b) analyse audio-taped consultations to see how these issues are currently discussed and c) develop and pilot a communication training module for palliative care clinicians. This could improve clinical practice, enhance patients' and families' psychological well-being and help patients to make appropriate deci ....Discussing prognosis and end-of-life issues is of key importance to palliative care patients and their families.

This could improve clinical practice, enhance patients' and families' psychological well-being and help patients to make appropriate decisions and prepare for their death.Read moreRead less
