This study will evaluate the accuracy of an experimental CGM measuring glucose continuously in the immediate vicinity of subcutaneous insulin delivery in people with type 1 diabetes (T1D) on insulin pump therapy. Glucose sensor accuracy will be evaluated over a 7 day period as well as infusion site patency and tolerability of the experimental device. Participants will be changed to a study pump for the duration of the study. In addition to utilizing the study device in a free living state, all participants will also undergo two high carbohydrate mixed meal challenges to assess the performance and accuracy of the study device.

The aim of this study is to determine whether regular consumption of cruciferous vegetables (e.g. broccoli, cabbage, cauliflower, kale) results in short-term improvement in measures related to cardiovascular disease risk, including blood pressure, arterial stiffness, glycaemic control, and circulating biomarkers of oxidative stress and inflammation. Twenty-eight participants (50-75 years) with mildly elevated blood pressure (systolic blood pressure 120-160 mmHg) will complete two 2-week interventions in a random order, separated by a 2-week washout period. During each intervention, participants will consume 4 servings/day (300 g) of vegetables as a soup (~500-600 mL/day). The 'active' soup will consist of cruciferous vegetables (broccoli, cabbage, cauliflower, kale) and the ‘control’ soup will consist of other commonly consumed vegetables (potato, sweet potato, carrot, pumpkin). Both soups will be approximately matched for energy, protein, fat, and carbohydrate content. All measurements will be performed at the beginning and end of each intervention period.

The Ear Health team currently runs a number of community-based ear health epidemiology, health promotion and telehealth projects. One of the key challenges faced for these projects is having the right equipment to obtain a clear otoscopic image of an ear drum that can be interpreted remotely by specialists.. Effective telehealth programs need appropriate equipment that can provide high-quality images of the ear and be easy to use, as the staff using the equipment may be nurses or health workers with little previous experience of performing otoscopy (ear examinations). During Ear Portal visits, otoscopy is conducted remotely by assistants and transmitted via a store and send method to specialists for review. If remotely provided otoscopic images are of poor quality, the ability to make a diagnosis is hindered resulting in the need for repeat assessment and delays in provision of care. This is a prospective sub-study which is linked to the PCH Ear Portal main study. Participants will be recruited opportunistically at community events including Telethon Weekend and the Cockburn Integrated Health NAIDOC event in October 2019 . Otoscopic still images and short videos will be obtained using the HearScope. The results will be saved and stored for later review and comparison by ENT/Audiologists along with supporting screening questionnaires and tympanometry. The sub-study results will be used to inform best technique (images or video) for obtaining views of the eardrum by research assistants during the Ear Portal main study to facilitate telehealth assessment by the multidisciplinary team (MDT).

Metformin is the first drug chosen to treat type 2 diabetes mellitus. However, the regulatory label warns against it use in people who also have chronic liver disease but there is little published data to support this warning. This study will investigate the safety and pharmacokinetics of metformin in patients with chronic liver disease (CLD) with or without type II diabetes mellitus (T2DM) who will be prescribed metformin (500 mg, immediate release, twice daily) for up to six weeks. We hypothesis that metformin at doses adjusted based on renal function can be safely administered to patients with CLD. Further, the pharmacokinetics of metformin in patients with CLD will be similar to those reported in patient with T2DM and no CLD.

Normal ageing is associated with a marked structural and functional reduction in the cerebrovascular system, which is linked to cognitive decline and dementia. Given the rapid increase in ageing and life expectancy, and the related medical costs associated with treatment of age-related disorders, identifying effective interventions to stop or delay the normal decline in cerebrovascular function are critical. Research has demonstrated that regular aerobic endurance exercise is associated with improved health of blood vessels in the brain in men aged 18-79 years, potentially also improving cognition and mood. This finding in endurance trained men may therefore help explain why there is a lower risk of cerebrovascular disease in this population. However, this research was undertaken in a small sample of male older adults and the function of the blood vessels in the brain to cognitive and chemical stimuli was not evaluated. Accordingly, we will investigate cerebrovascular function, mood and cognition in aerobic endurance trained and untrained middle-aged and older (50-80 years) adults. The significance of this project is that it may be the first research study to demonstrate that regular aerobic endurance training is associated with improved brain blood vessel health, cognitive function and mood in a population that is at risk of cerebrovascular disease, which is linked to cognitive decline and dementia.

Globally, by 2050, every one in two people will be myopic. It is in fact a vision-threatening public health issue. Interestingly, it has been found that there is seasonal variation in ocular growth with less growth during summer months. Additionally, ocular parameters such as eye length have also been reported to exhibit a diurnal rhythm. This observational study aims to investigate variations in ocular parameters over 24 hours and to evaluate their associations with the body clock and daily light exposure among healthy young adults.

The aim of this randomised control trial is to evaluate the efficacy of a lunchbox program on the nutritional content of student lunchboxes. The program will run for approximately 10 weeks. Ten primary schools in the Hunter New England, Central Coast and Mid North Coast regions of NSW will be randomly allocated to one of two intervention arms or a waitlist control group. The program aims to support parents/carers to swap what is packed in lunchboxes from sometimes to everyday food, through the use of weekly support messages delivered through a school communication app, with or without additional support.

The purpose of the study is to determine if a strength-focused exercise program prior to surgery can improve participant’s physical function, reduce time in hospital and complications from surgery, and help restore physical function and quality of life post-surgery. Who is it for? You may be eligible for this study if you are an adult who is having surgery due to head and neck cancer at Fiona Stanley Hospital in Western Australia. Study details Participants in this study will receive one of three different treatments: 1. A ‘pre-habilitation’ exercise program, involving a strength and aerobic exercise program prior to surgery. Participants in this group will also receive an education program. 2. The same pre-habilitation program as group 1, plus an additional 6-week post-surgery rehabilitation program. 3. Usual care including an education program, and routine post-operative care. Participants in this study will be randomly allocated to one of these treatment groups, and will also need to complete a battery of physical function tests including a timed up and go test, grip strength, step test and DEXA scan. You will also need to complete a number of self reported questionnaires relating to your quality of life, quality of recovery and functional ability. It is hoped that this research will help determine if a pre-habiltiation program is effective at improving post-surgery outcomes in head and neck cancer patients.

Accurate quantification and analysis of jumping and landing technique is one method to improve sport performance. The current gold-standard method for quantifying movement is three-dimensional biomechanical analysis in a motion analysis laboratory. However, due to financial, time, and logistical constraints, this method is frequently inaccessible to the wider sporting population. Wearable inertial measurement units (IMU) – consisting of micro-sensors– have been used as a cost-effective, accessible option that can provide real-time feedback of performance. To further promote wearable IMU use, it is important to evaluate the validity and reliability compared to the previously established method of motion analysis – three-dimensional biomechanical analysis. Study hypothesis: that wearable IMUs are a valid and reliable alternative to quantifying jumping and landing movements compared to three-dimensional biomechanical analysis.

The purpose of this study is to see if melatonin supplementation can help improve sleep in women receiving hormone blocking therapy for breast cancer. Who is it for? You may be eligible for this study if you are aged 18 or over, have stage 1-3 breast cancer, are taking hormone blocking therapy and have trouble sleeping. Study details Participants in this study will be randomised by chance into two groups. One group will take melatonin tablets every evening before bed for 12 weeks. The other group will take a placebo tablet every evening before bed for 12 weeks. Neither the participants nor the researchers will know which participants are taking which tablets. All participants will complete questionnaires, complete a medication diary and wear an atigraph watch to measure your sleep. It is hoped this research will demonstrate the usefulness of melatonin in improving sleep in breast cancer patients.
