This study aims to assess the effect of nicotinamide (vitamin B3) on incidence of nonmelanoma skin cancer and actinic keratoses. Who is it for? You may be eligible to join this study if you are aged 18 years or more and have had at least two confirmed nonmelanoma skin cancers within the previous 5 years. Trial details Participants in this trial will be randomly (by chance) allocated to one of two groups. Participants in one group will take two 500mg nicotinamide (vitamin B3) tablets daily for 12 months, whilst those in the other group will take two placebo (inactive) tablets daily instead. Participants will not know which group they are in until the end of the trial. Participants will be regularly assessed over the treatment period and for 6 months after the treatment period to determine the efficacy of nicotinamide in preventing nonmelanoma skin cancer.

The purpose is to investigate whether HIV and HIV medication can affect certain areas of brain function. This study will look at possible changes in brain function including memory, concentration and thought processes to see if there are any differences between the two doses of efavirenz used in the Encore1 study and also the level of efavirenz in the blood http://clinicaltrials.gov/ct2/show/NCT01516060?term=Encore1&rank=4

Gestational diabetes is a form of diabetes, or glucose intolerance, that develops during pregnancy. Women who have had gestational diabetes are many times more likely to develop type 2 diabetes in the future compared with women who have normal blood glucose levels during pregnancy. Thus, it is important to screen these women after they have given birth to see whether they have type 2 diabetes, such that it can be treated, or to see whether they are on the way to developing type 2 diabetes (have impaired glucose tolerance), such that preventative changes can be made. The best way of detecting type 2 diabetes and impaired glucose tolerance is with an oral glucose tolerance test, and this test is recommended by many health organisations, such as the Australasian Diabetes in Pregnancy Society, to be undertaken in the early postpartum period. Despite this, evidence shows that many women who have had gestational diabetes do not receive this follow up testing. The DIAMIND study is aiming to test whether a text message based reminder system (using mobile phone technology) will increase the number of women who have had gestational diabetes who undertake oral glucose tolerance testing in the postpartum period.

This study evaluates the efficacy of a novel, online support program that targets Type 2 diabetes self-management and dysphoria symptoms in aiming to improve glycaemic control and emotional well-being. Secondary aims of the program are to improve behavioural outcomes (physical activity, dietary intake, and medication adherence), self-efficacy for diabetes self-care, and quality of life. Program evaluations include cost-effectiveness and qualitative outcomes, for example implementation feasibility, user satisfaction, program usability and acceptability.

Gut emptying is of central importance to blood glucose levels after meals and is a major determinant of overall blood glucose control in diabetes. Blood glucose levels and insulin release after meals are also influenced by secretion of hormones from the gut in response to a meal. The gut hormones stimulate insulin secretion in response to raised blood glucose levels. However fat, rather than carbohydrate may be the most potent stimulus for gut hormone release. We aim to measure the effect of gut emptying and gut hormone release on high blood glucose levels in youth with type 1 diabetes (T1D). Gut hormone based therapy may normalize gut emptying and/or suppress hormones therefore reducing high blood glucose levels after meals in youth with T1D. Hypothesis: In young people with type 1 diabetes (i) Gut emptying is slower than in controls (ii) Gut hormone secretion is normal in comparison to controls (iii) Nervous system dysfunction relates to gut emptying

Gut emptying is of central importance to blood glucose levels after meals and is a major determinant of overall blood glucose control in diabetes. Blood glucose levels and insulin release after meals are also influenced by secretion of hormones from the gut in response to a meal. The gut hormones stimulate insulin secretion in response to raised blood glucose levels. However fat, rather than carbohydrate may be the most potent stimulus for gut hormone release. We aim to measure the effect of gut emptying and gut hormone release on high blood glucose levels in youth with cystic fibrosis (CF). We will determine whether the adequate replacement of pancreatic enzymes improves blood glucose levels after meals in youth with CF. Our findings for gut hormone release will inform investigation of potential therapies, eg. free fatty acid therapy, to prime gut hormone release to reduce the impact of high blood glucose levels on the complications associated with CF. Hypothesis : In young people with CF i) Gut emptying of a high fat/carbohydrate meal will be abnormally rapid. ii) Abnormal emptying will be associated with high blood glucose levels after a meal and reduced gut hormone secretion and insulin responses. iii) These abnormal responses will be normalised by pancreatic enzyme supplementation.

The primary purpose of the clinical trial is to test the hypothesis that day surgery patients who listen to music during their preoperative wait will have statistically significantly lower levels of anxiety than patients who receive routine care.

This study investigated the effect that participation in a 40-minute live music program, three times a week for eight weeks, had on agitation, emotions and quality of life in older people with dementia. A randomized cross-over design, with music and reading control groups, was employed.

The aim of the proposed research is to evaluate the efficacy of MoodGroup, an online group therapy intervention for the treatment of depression in Australian adults. The study will use a randomised controlled trial design (RCT). MoodGroup is a 9-week intervention that has been adapted from a face-to-face group therapy program for depression. Using cognitive behavioural therapy, participants will learn skills and techniques to reduce their depressive symptoms.

It is currently unclear whether there is a benefit for smokers to act immediately on impulses to quit smoking, and if so, whether delay is detrimental in its own right, or only if the time is not used productively for appropriate planning. It is also unclear whether planning can effectively be carried out after quitting, allowing smokers to quit spontaneously yet still effectively plan for the maintenance of their attempt. The study is designed to untangle these issues, specifically exploring the benefit of structured support and the possible positive effects of recommending immediate implementation, apart from any delay required by the help to be used (e.g., medications that need to be used for a period before quitting). We hypothesize that among smokers who seek help, 6-month sustained abstinence assessed on an intention-to-treat basis will be greater among: 1. Those encouraged to quit immediately as compared with those encouraged to quit to their own timetable; 2. Those who are provided with a structured planning program based around the development of implementation intentions (if-then statements designed to increase the likelihood that a goal is attained), as compared with those only provided motivational messages and general encouragement to plan; 3. And that these two effects will be independent. We will also explore the outcomes as a function of compliance with the recommended strategies, and whether the trial outcomes differ for different outcome measures (e.g. point-prevalence cessation, different imputation strategies for dealing with missing cases).
