What does health research mean to you?

Health research is a spectrum, from making new and amazing discoveries through to identifying the best ways to implement best practices in delivery of care. We tend to see the delivery side of the pipe and forget that we have so much more to learn – about our biology, our susceptibilities, what most of our genes do (we are largely still in the dark), how diseases are caused, what might prevent them….  So many questions! Luckily for me in my job, I do get to see the whole pipeline – from new understandings of how worms move (which helps us understand diseases like Parkinson’s), to new therapeutics that we’ve helped develop and may be tested on our patients through to identifying new risk factors and ways to avoid exposures. There is a lot going on but there is always so much more to do. Our scientific ignorance is the biggest gap in achieving better quality of life

How does health research contribute to a healthier, wealthier, smarter Ontario?

The question is really, why Ontario? Why can’t we just let some other country develop better ways to provide care and we can then adopt them? Well, we could and we’d always be a few years behind. We’d never have control (of price, of coverage, of problems specific to Ontario). We’d yearn for our kids to visit as they moved to other parts of the world to make a difference. We’d fondly remember the world-class care we used to receive because the best physicians wanted to train here and improve the outcomes of their patients, here. We’d say goodbye to the burgeoning companies that pop up and grow in Ontario because we have a strong health research sector. We’d also lose our desire to make not only our own lives better, but also the lives of those so much less fortunate than Ontarians. That’s why.

Research Spotlight: Sinai Health System

Short-term insulin therapy successfully induces remission in Type 2 diabetes

A new study lead by researchers at Mount Sinai Hospital, part of Sinai Health System, has shown that early intervention with short-term intensive insulin therapy for four weeks can successfully induce a remission of Type 2 diabetes that lasts for up to one year thereafter.

The study was led by Dr. Ravi Retnakaran, an endocrinologist with Leadership Sinai Centre for Diabetes at Mount Sinai Hospital, and has just been published in BMJ Open Diabetes Research and Care. The findings of Dr. Retnakaran and his team show that the earlier that short-term intensive insulin therapy was administered after the diagnosis of diabetes, the more successful it was in sustaining a 48 week remission.

Short-term intensive insulin therapy is typically administered for a period of two to four weeks and can decrease insulin resistance, reduce glucagonemia, improve pancreatic beta-cell function and induce a remission that can last up to one year in just under 50% of patients. The study showed that those who had been diagnosed within the preceding two years and then undergone the treatment had the longest sustained remission. Patients who had sustained remission had better baseline beta-cell function that was preserved across the one year after stopping the treatment.

On the road to longer term remission

“This study points us in a very important direction in our quest to address one of the most prevalent chronic diseases today. The first point is the clear benefit of short-term intensive insulin therapy, and the second is the importance of early intervention within the first few years after diagnosis.   Our quest is to better understand the factors that determine remission so that we can offer long term solutions for our patients. The current study tells us that one key factor is early intervention with short-term insulin therapy during a window of opportunity that only exists in the first few years after diagnosis,” said Dr. Retnakaran.

Home to world-class diabetes researchers and research centres

Dr. Retnakaran, an endocrinologist with Leadership Sinai Centre for Diabetes at Mount Sinai Hospital and an investigator with the Lunenfeld-Tanenbaum Research Institute, collaborated with Drs. Bernard Zinman and Caroline K. Kramer, both of Leadership Sinai Centre for Diabetes at Mount Sinai Hospital and Lunenfeld-Tanenbaum Research Institute, in conducting a major clinical trial known as RESET-IT that aims to induce remission of Type 2 diabetes. The institute ranks amongst the top diabetes research centres in the world.

More than three million Canadians have Type 2 diabetes and the World Health Organization recently warned that rates have quadrupled since 1980, with 422 million people worldwide living with diabetes. The rate is expected to double in the next 20 years.
