JCU diabetes researcher heads to Toronto

James Cook University Diabetes researcher Sean Taylor is heading to Canada and Germany in search of ways to improve care and management of diabetes in the remote islands of the Torres Strait.

Mr Taylor leaves Cairns this week on a seven-week study tour, supported by a $5,000 Heart Foundation Collaboration and Exchange Award.

“The Torres Strait region has Australia’s highest prevalence of type 2 diabetes, with one third of the adult population affected,” he said.

“Patients and medical staff also face the added problems of being in a remote location, where many of the healthy food choices recommended for diabetics are not necessarily available or affordable.”

Originally from the Torres Strait, Mr Taylor is a Research Fellow and Doctor of Public Health candidate at James Cook University’s Centre for Chronic Disease Prevention.

He will visit the Banting & Best Diabetes Centre in Toronto, Canada’s leading centre of excellence for innovation in diabetes research, education, and clinical care.

“They’re an important collaborator for us because Canada’a First Nations people face chronic disease problems similar to those experienced by Torres Strait Islanders, and also because of similarities between the Australian and Canadian health systems,” he said.

In Canada Mr Taylor will focus on the behavioural aspects of diabetes management, including patients’ reluctance to use insulin after their doctors have prescribed it.

“There are many reasons for this, and we need to understand it better because it’s a serious barrier to those patients getting the best care available.

“People with diabetes can achieve a good quality of life, if the disease is well managed, so we need to find the smartest and most effective ways to help them do that.”

At the University of Duisburg Essen in Germany Mr Taylor will consult with experts in the use of digital and social media to promote health.

“As well as suffering a higher rate of type 2 diabetes, Torres Strait Islanders with diabetes have much poorer outcomes compared with the non-Indigenous population,” he said.

“The team I’ll be meeting with in Germany has expertise not just in using digital media to support health and medical care, but also in carefully evaluating the usage of social media.

“I hope to find new ways to use those tools to help improve the connection between Torres Strait Islander diabetics and their health and medical support networks.

“For example, if we could improve the rate of people returning to the clinic for check-ups, and encourage more to take their medication consistently, that would make a big difference to their long-term health.”

Mr Taylor says that despite the worrying statistics for type 2 diabetes in the Torres Strait, there is some good news.

“It’s important to focus on those positive achievements, and to share them. People living on Murray Island, for example, have an excellent source of healthy protein in the sardines, which they catch in great numbers.

“Finding affordable and healthy food can be a challenge in a remote area, and digital and social media might provide some ways to share news of what’s working well on different islands.”

UQ Public Health researcher finds diabetic women face higher risk of stroke

A review of more than 60 studies has shown that women with type 2 diabetes have a 27 per cent higher risk of stroke than men with diabetes.

Professor Rachel Huxley, from the University of Queensland, collaborated with researchers from leading public health units at the University of Cambridge (UK) and The George Institute for Global Health.

The UQ School of Population Health researcher said the study was the first to reveal that the risk of diabetes-related stroke significantly differs in women and men.

“Research has previously shown that diabetes confers a greater risk of having a heart attack in women than men, and now we have shown that this gender difference also extends to stroke,” Professor Huxley said. “Data was pooled from three-quarters of a million people, including more than 12,000 individuals who had suffered strokes, both fatal and non-fatal.

“Our analysis of the data showed, in comparison to men with diabetes, women with the condition had a 27 per cent higher relative risk of stroke even after taking into account other risk factors such as age and blood pressure.”

Diabetes is a global health concern, currently affecting an estimated 347 million people worldwide.

It is predicted to increase by more than fifty per cent over the next decade due to the prevalence of overweight, obese and physically inactive people.

“With diabetes on the rise, there is an urgent need to establish why the condition poses a greater cardiovascular health threat for women than men,” she said.

“We don’t yet understand why diabetes is more hazardous for women in determining their cardiovascular risk compared with men, but existing studies suggest that it may be linked to obesity.

“Men tend to become diabetic at lower levels of body mass index compared with women.

“Consequently, by the time women develop diabetes and begin receiving intervention from a GP, their levels of other cardiovascular risk factors—including BMI—are higher than in men with diabetes who may have been picked up and treated at an earlier stage of the condition.

“It may be this chronic exposure to high levels of cardiovascular risk factors in the lead up to developing diabetes that may be responsible for the greater risk of stroke that we see in women with diabetes than in similarly affected men,” said the UQ Public Health professor.

University of Newcastle researchers say sleep linked to diabetes

Getting less than six hours sleep each night (compared to seven hours) may increase type 2 diabetes risk by 30 per cent but has less impact on heart disease than previously thought, researchers from the University of Newcastle have found.

In the largest study of its kind, the team led by Hunter Medical Research Institute statistician Dr Elizabeth Holliday and epidemiologist Professor John Attia analyzed data from 240,000 people in the NSW “45 and Up Study” and tested for potential contributing factors such as existing illnesses and medications.

“A number of previous studies have looked at sleep deprivation and the risk of both diabetes and cardiovascular disease but the statistical power was relatively low and not all of them had corrected for potential confounders that can affect results,” Professor Attia said.

“Once we adjusted for the confounders the risk for heart disease went away, other than in those who had prior illness, but the relationship with type 2 diabetes remained significant no matter what we adjusted for.”

Of the 240,000-strong cohort, more than 7,000 people fell into the risk category of fewer than six hours’ sleep, with the findings just published in the international journal PLOS ONE.

Dr Holliday said it was surprising to see the cardiac link diminish.

“The relationship between short sleep and cardiovascular disease has been widely reported but results across various studies have been inconsistent. We were able to show that this relationship might be confounded by pre-existing illness, which we didn’t see with diabetes,” the University of Newcastle statistician said.

The researchers believe the results tie in with previous studies where volunteers became insulin resistant after several consecutive nights of acute sleep deprivation.

“There are other changes in hormones such as ghrelin and leptin that regulate hunger and the feeling of satisfaction after eating,” Dr Holliday added.

“When you’re sleep deprived you tend to crave carbohydrates and eat more sweets.”

Tips to improve sleep quality include exercising before 6 p.m., abstaining from caffeine in the afternoon and early evening, reducing stimulation from social media and texts, and observing regular bed and rising times.

“GPs should be interested in this result because there are a number of people with pre-diabetes who are at high risk,” Professor Attia said.

“Getting more sleep might be a way of improving insulin sensitivity and delaying the onset of frank diabetes. “It may also be a factor for people who are already diabetic and having trouble getting glucose control.”

Monash University medical researchers find brain atrophy linked with cognitive decline in diabetes

New research at the Monash University Department of Medicine has shown that cognitive decline in people with Type 2 Diabetes is likely due to brain atrophy, or shrinkage, that resembles patterns seen in the early stages of Alzheimer’s disease.

Dr Chris Moran and Associate Professor Velandai Srikanth of Monash University led the first large-scale study to compare brain scans and cognitive function between people with and without Type 2 Diabetes Mellitus (T2DM). They found that brain atrophy, rather than cerebrovascular lesions, was likely the primary reason for cognitive impairment associated with T2DM.

The World Health Organization reports that more that more than 347 million people worldwide live with diabetes and around 90 per cent of these cases are Type 2.

Associate Professor Velandai Srikanth of Monash University’s Department of Medicine said the findings had important implications for Australia’s ageing population.

“Type 2 Diabetes and dementia are both highly common disorders affecting the ageing population and this research shows that there may be a mechanistic link between them. Indeed, generalized brain atrophy may be the key driver of cognitive decline in Type 2 diabetes and such atrophy is also commonly seen in people with dementia,” Associate Professor Srikanth said, adding that by 2031 it is estimated that around 3.3 million Australians will have diabetes. The burden of dementia in the population will be greatly increased if a significant number of these individuals experience cognitive decline.

The research built on previous studies that had shown there may be a greater risk of future dementia in people with T2DM. However, it was unclear whether T2DM was a causal factor for the development of cognitive impairment, and if so, what mechanisms may be involved.

The researchers compared cognitive function and magnetic resonance imaging (MRI) scans of the brain in more than 700 people with and without T2DM.

Those with diabetes performed less well in certain cognitive tests and had greater shrinkage in specific regions of the brain, which appeared to drive the differences in cognitive function. Although the researchers found that participants with diabetes also had more strokes on MRI, this did not explain the cognitive differences between groups.

The findings, published in Diabetes Care, will lead further research in trying to identify why people with Type 2 Diabetes develop brain atrophy, and how such atrophy may be prevented or slowed.

UQ Public Health study suggests type 2 diabetes treatable with Chinese medicine

Traditional Chinese medicine could be a key weapon in the treatment of type 2 diabetes, a joint international study has found.

Researchers, including the University of Queensland’s Dr Sanjoy Paul and Peking University’s Professor Lilong Ji from Beijing, have found that conventional drugs were significantly more effective when used alongside traditional Chinese medicine in the treatment of type 2 diabetes.

The study involved a controlled clinical trial of 800 type 2 diabetic adults, comparing anti-diabetic drug Glibenclamide as a stand-alone treatment and treatment with Glibenclamide in conjunction with traditional Chinese medicine.

Dr Paul, who is director of the Queensland Clinical Trials and Biostatistics Centre in UQ’s School of Population Health, said results showed patients treated with traditional Chinese medicine were more than a third less likely to experience hypoglycemia—dangerously low levels of blood sugar—than those treated with Glibenclamide only.

“They were also less likely to experience other symptoms of diabetes, including fatigue, hunger and palpitation,” Dr Paul said.

“Traditional Chinese medicine has long been used to treat diabetes in China and around the world but until now there has been a lack of evidence regarding its safety and efficacy.

“This absence of scientific understanding has caused skepticism and criticism about traditional Chinese medicine.”

Dr Paul said more studies were needed to interpret just how traditional Chinese medicine worked to reduce hypoglycemia, but the study results highlighted its potential to reduce the treatment gap in developing countries where diabetes was at epidemic proportions.

“A vast majority of people in developing countries depend on herbal medicine for basic health care,” Dr Paul said. “The findings of this study may improve the safe delivery of effective health care to people who may otherwise be unable to access treatment.”

The study is the largest scientifically designed clinical trial evaluating the safety and efficacy of traditional Chinese medicine on hypoglycemic control in patients with type 2 diabetes.
