HIV-associated dementia

RESEARCH STUDY

We are currently recruiting healthy men aged 45 years and over for a study investigating the link between HIV infection and dementia.

In conjunction with St Vincent’s Hospital, the University of New South Wales and Neuroscience Research Australia (NeuRA), the study aims to estimate the prevalence of memory and concentration difficulties in older individuals with long-term HIV infection, as well as the means (if any) by which long-term HIV infection contributes to the incidence of an illness like dementia.

An important part of this study is recruiting healthy control participants as a comparison group. To participate, you must be:

  • male
  • 45 years old or older
  • in good health, with no psychiatric or neurological disoders

We will ask you to make two visits to St Vincent’s Hospital in Sydney over an 18 month period. Each visit will last two hours, during which we will ask you to participate in a neuropsychological test of attention, memory, visuo-spatial and language function. We will also ask to take an MRI scan of your head (this involves lying quietly in the MRI scanner for 45 minutes).

If you so chose, we can make the study results available to your doctor of choice. We will reimburse your travel/parking expenses.

To participate, or for more information contact Dr Lucette Cysique on 0431 576 710 or via email: lcysique@unsw.edu.au

Abdominal muscle stimulation to improve bowel function in spinal cord injury

Bowel complications, resulting from impaired bowel function, are common for people living with a spinal cord injury (SCI). As a result, people with a SCI have high rates of bowel related illness, even compared with those with other neurological disorders. This includes high rates of abdominal pain, constipation, faecal incontinence and bloating. These problems lower the quality of life of people with a SCI and place a financial burden on the health system. A treatment that improves bowel function for people with a SCI should reduce illness, improve quality of life and lead to a large cost saving for health care providers. Bowel problems have traditionally been managed with manual and pharmacological interventions, such as digital rectal stimulation, enemas, and suppositories. These solutions are usually only partially effective, highlighting the need for improved interventions. The abdominal muscles are one of the major muscle groups used during defecation. Training the abdominal muscles should improve bowel function by increasing abdominal pressure. During our previous Abdominal FES research with people with a SCI, we observed that Abdominal FES appeared to lead to more consistent and effective bowel motion. However, this evidence remains anecdotal. As such, we are going to undertake a large randomised controlled trial to investigate the effectiveness of Abdominal FES to improve the bowel function of people with a SCI. This study will make use of a novel measurement system (SmartPill, Medtronic) that can be swallowed to measure whole gut and colonic transit time. We will also assess whether Abdominal FES can change constipation-related quality of life and the use of laxatives and manual procedures, as well as the frequency of defecation and the time taken. A positive outcome from this study is likely to lead to the rapid clinical translation of this technology for people living with a SCI.
