  • Strength training and non-invasive brain stimulation to improve walking and balance in Parkinson's disease

    Parkinson's disease is characterised by a loss of dopamine in the brain that leads to movement dysfunctions such as slowness, impaired balance, resting tremor and muscle stiffness. The loss of dopamine also results in maladaptive brain plasticity, or an inability of the brain to adapt to a new stimulus, which is believed to underpin motor dysfunctions. Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation that uses low level electrical currents to alter brain plasticity and make the brain more receptive to stimuli, such as resistance training. The use of resistance training has been shown to improve movement function in patients with Parkinson's disease, however the concurrent use of both resistance training and tDCS has not yet been investigated. Therefore, the purpose of this study is to determine the effectiveness of tDCS applied during 6 weeks of resistance training on walking and balance in patients with Parkinson's disease. Participants will be randomly allocated to receive either resistance training with tDCS, resistance training with sham tDCS, or standard care. Resistance training of the lower body will be performed 3 times per week for 6 weeks, one-on-one with an exercise physiologist in a specialised gym. Real tDCS will be delivered at 2mA for the first 20 mins of exercise. Sham tDCS will be delivered for 15 seconds, after which the unit will become inactive. It is hypothesised that the benefits of resistance training will be enhanced in patients receiving tDCS in comparison to those receiving sham tDCS, or standard care.

  • Regional glucose infusion on gut function

    The proposed study is designed to (i) compare the glycaemic and incretin hormone responses after administration of glucose into the duodenum vs. ileum, and (ii) evaluate the incretin effect (IE) and gastrointestinal-mediated glucose disposal (GIGD) induced by intraduodenal (ID) and intraileal (II) glucose infusion using intravenous (IV) ‘isoglycaemic’ clamp, in both healthy subjects and patients in type 2 diabetes. Secondary objectives are to evaluate the effects of intraduodenal vs. intraileal glucose on blood pressure (BP), heart rate (HR) and superior mesenteric artery (SMA) blood flow.

  • Bile acids and glycemic control in type 2 diabetes

    The proposed study is designed to determine, in patients with type 2 diabetes, (i) whether blood glucose, incretin hormone (ie. glucagon­like peptide­1 (GLP­1) and glucose­dependent insulinotropic polypeptide (GIP)), insulin, glucagon, and fibroblast growth factor­19 (FGF­19) concentrations in response to a small intestinal glucose infusion (2 kcal/min) are modified by intrajejunal infusion of taurocholic acid (TCA), (ii) the effect of TCA on small intestinal glucose absorption, and (iii) the relative contribution of the actions of GLP­1 to the lowering of glycaemia by TCA, using the specific antagonist, exendin (9­39). Additionally, changes in blood pressure (BP), heart rate (HR) and superior mesenteric artery (SMA) blood flow in response to intrajejunal glucose infusion will be evaluated, in the presence and absence of intrajejunal TCA and intravenous exendin (9­39).

  • Cardiac Magnetic Resonance Imaging and echocardiography in the detection of cardiotoxicity in cancer patients: A feasibility study

    The primary purpose of this study is to determine the feasibility of using cardiac MRI scans, cardiac ultrasound and blood tests to detect changes in heart function following completion of chemotherapy and/or radiation therapy for cancer. Who is it for? You may be eligible to join this study if you are aged 18 or over, and have been diagnosed with breast cancer, Hodgkin's lymphoma, Non-Hodgkin's lymphoma, leukaemia or other intra-thoracic/upper gastrointestinal malignancies such as cancer of the oesophagus or thymoma, for which chemotherapy and/or radiotherapy have been prescribed. Study details All participants in this study will undergo additional cardiac screening tests at timepoints before and after chemotherapy/radiation therapy up to 12 months following the end of therapy. These tests will include MRI scans, cardiac ultrasound scans and blood samples being taken. Results from these tests will be used to assess changes in cardiac function caused by the cancer therapy. It is hoped that the findings of this feasibility trial will ultimately aid early identification of heart injury due to cancer therapy, and thus enable prevention strategies and early treatment options in these patients.

  • Evaluation of a safety-planning smartphone application for improving capacity to cope with suicidal ideation among at-risk individuals.

    The aim of this research is to evaluate the functionality, efficacy, and utility of a new safety planning smartphone application. The trial will involve including the use of the smartphone application into existing Monash Health mental health services. Participants will include 60 patients who have experienced recent suicidal ideation or behaviours. Participants will be recruited by their treating mental health clinician. First, research staff will train the treating clinicians and participants in the use of the smartphone application, and conduct baseline measurement of suicide ideation and/or behaviour, as well as suicide resilience using self-report measures. Participants will then undergo 'treatment as usual' under the management of their treating clinician for a period of two months. Research staff will then conduct post trial measurement of suicide risk and resilience along with qualitative data on smartphone application functionality and utility. Data on smartphone application usage will be collected via Google analytics software. This information will not include personal information stored in the application.

  • Evaluation of optical coherence (OCT), imaging to examine the structure and form of coronary plaques following a heart attack.

    Patients who present with an acute coronary syndrome remain at high risk of further events in subsequent years. Better identification of individuals at high risk can allow better targeting of novel therapies and resources. This study will create an imaging bio-bank that enables testing of multiple novel strategies involving new imaging, image analysis and biomarker approaches alone or in combination for improved risk stratification and targeting of prevention. Prospective follow-up in the cohort for outcomes enables the predictive value to be tested in a pilot data setting.

  • The effectiveness of pre-travel health advice on illness rates in Western Australians returning from Bali, Indonesia.

    The project will use both a randomised control trial and prospective cohort design. Participants will be Western Australian travellers planning to depart for Bali. Half of participants will be randomly allocated into an intervention group and receive prepared online travel health information. After returning from Bali, both the intervention and non-intervention group will be invited to complete an online survey with questions concerning any communicable disease symptoms and health impacts.

  • A controlled trial of Casein Phosphopeptide - Amorphous Calcium Phosphate (CPP-ACP) toothpaste in 6 year old children

    This study aims to determine - the effectiveness of using a CPP-ACP toothpaste in preventing dental caries in children - the microbial changes in plaque such as the reduction in decay causing bacteria Participants will attend routine dental examination appointments at public oral health services. In addition to standard examination a sample of plaque will be taken by swabbing selected teeth with a small brush. A questionnaire will be completed by the participant's parents regarding medical, social, toothbrushing and dietary histories. Dental radiographs will be taken at the recruitment appointment. All identified treatment will be undertaken. At the first appointment, a participant's toothbrushing group will be randomly allocated. The allocation is either the CPP-ACP toothpaste or the placebo toothpaste (blinded groups) or commercial fluoridated toothpaste (non blinded). For the blinded groups (CPP-ACP and placebo), the toothpaste packaging will be marked with a digital code, but the content will not be known to the participants, the clinicians or the investigator. The codes will be provided to the chief supervisor of the study. Only after the statistical evaluation is completed will the decoding occur. All the toothbrushes and toothpaste will be provided free of charge for the duration of the study. Participants are asked to brush twice daily will the allocated toothpaste. Compliance will be monitored by a phone call questionnaire at 3 and 9 months and in person at 6 and 12 month . The examination appointment will be repeated at 6 months and 12 months. Dental radiographs will be taken at 12 months.
