Engaging Primary Care in Research: Not Always an Easy Task
Stella Song ROP Summer 2016 |
I am Stella Bing Xin Song, currently a second year student studying pharmacology and psychology at University of Toronto. I was fortunate to be a part of the 2016 Research Opportunity Program (ROP) supervised by Dr. Pascal Tyrrell in the Department of Medical Imaging at University of Toronto.
In the end, it was an exciting and valuable experience to plan out and execute this research project. Most importantly, I had the pleasure to join Dr. Tyrrell’s lab and meet his team. I am grateful for all the help and support which I have received throughout my time at the lab. I look forward to continuing to work as a member of Dr. Tyrrell’s lab.

U of T Research Opportunity Program – Clare Sheen
Clare Sheen is an undergraduate student at the University of Toronto, in process of completing her Bachelor of Sciences in Genomics and Microbiology/Molecular Genetics. She was a 2015-6 Research Opportunity Program (ROP) student working on designing the Medical Image Network Enterprise (MiNE) interface for Dr. Pascal Tyrrell from U of T’s Department of Medical Imaging. She is currently a social director on the Life Science Student Network exec team and a volunteer at U of T’s Agrawal Lab where she helps with Drosophila experiments. She continues to seasonally work as a student camp teacher in the summer.
At the Research Opportunity Program (ROP) fair on March 3rd, U of T ROP students from different departments came together to share their research. A mock-up of the MiNE interface was presented in PowerPoint with the goal of increasing user engagement and encouraging the development of a medical imaging research community. Some features of the interface are presented below.
Back to Basics… Midpoint Thoughts from an ROP Student
Through the ‘Research Opportunity Program‘ (ROP) for second year students at U of T, I have been working on a project about physicians’ willingness to use MRI as the front-line diagnostic imaging technology for carotid stenosis patients. For a description see here.
After a recent discussion with Dr. Tyrrell (my supervisor), and as I approach the midpoint of my ROP project, I thought it would be a good idea to review some of my background knowledge of carotid stenosis from my work in the Fall term. Having a certain amount of independence while working on this project has been a great experience, but it also means I am responsible for keeping track of my own learning.
Begrudgingly, I’ll admit that this ‘self-directed’ review process has shed new light on the usefulness of midterms in other courses. However, I still prefer this project-based review format. It has allowed me to review necessary information to make sure that it is fresh in my mind. Now I feel more prepared to begin the second half of the project. I’m looking forward to a major meeting this month and all the other exciting parts of the project to come.

Ethics Schmethics?
Today, it may seem obvious that the first step of any research project should be to complete a proposal for ethics review. But why do we need ethical standards? While helping to complete an ethics form for a project I’m working on, I wondered if scientists perhaps made more ‘progress’ before ethical considerations became commonplace. Even if this was the case, research is certainly better now, when institutions and procedures protect patients’ and research subjects’ rights.
It also seems that scientific research in the 18th and 19th centuries tended to be somewhat more haphazard than it is now, and almost certainly less ethical. For example, Dr. Edward Jenner tested his smallpox inoculation hypothesis for the first time on an eight-year-old
boy in 1796, with little preliminary understanding and no certainty that the patient would not be severely harmed.
Scientists were often fairly independent, acting based on their own curiosity to advance knowledge. Fortunately, research standards have evolved significantly since then. Ethics have been a major part of the transition, as ethical standards help to ensure that scientific research does not cause harm to researchers or subjects. The shocking Stanford Prison Experiment, just one example, shows that physical and psychological damage can occur if study participants’ rights are not upheld through ethics. College students with no criminal record were asked to play the role of prisoners and prison guards, the ‘guards’ became brutal and cruel, while the ‘prisoners’ became stressed and depressed. The experiment was terminated early, after only six days.
Fortunately, much has changed since the emergence of modern science in the 20th century. The current structure of research, including working in teams and undergoing peer review, helps to ensure a high standard of practice. Nevertheless, ethical issues in science remain. Researchers who work with human participants can become quite focused on the minutiae of their work, so Research Ethics Boards have an important mediating role. They provide an experienced, unbiased viewpoint that weighs the potential benefits of the research against any harm that may come to participants. Even if an ethical review sometimes slows the pace of scientific progress, it provides an essential foundation and structure for research, to the benefit of participants and researchers alike.

All the World’s a Stage
the New York Times Twitter account was updated nine minutes ago, and National Geographic tweeted three minutes ago. This expectation of speediness applies equally to scientific advances as it does to international affairs.
Maybe it also explains the popularity of other media sources like TED talks, which often explain complex ideas in an engaging and understandable format. A personal favourite is “The best stats you’ve ever seen” by Hans Rosling. In his talk, Rosling explains the importance of little-known global public health data that shows the progress (or lack thereof) made by different countries over the past few decades.
A more recent talk on a similar topic is also informative. One would be hard-pressed to find a paper or article that presents the same information with as much clarity and appeal.

Kiersten Thomas – ROP summer 2015 |
Hello, I’m one of Professor Pascal Tyrrell’s summer ROP students and a second year Immunology Specialist student at the University of Toronto. I have just completed my summer research project investigating the cost-effectiveness of using MRA to evaluate asymptomatic carotid artery stenosis.
I learned a lot and had an amazing time conducting research with Dr. Eli Lechtman and my ROP partner Indranil Balki. Using TreeAge Pro to create and analyse decision trees, we demonstrated that the additional information gained from an MRA/IPH scan increases the effectiveness of MRA when imaging carotid artery stenosis.
Our research suggests that the additional information of the presence of intraplaque hemorrhage (IPH) would lead to better patient care, reducing long-term stroke risks. This means that MRA/IPH can be cost-effective or even dominant when compared to the current imaging strategy that uses standard ultrasound as a first-line imaging modality, for evaluating all degrees of asymptomatic carotid artery stenosis. Take a look at my timeline to see some of the highlights of my summer!
Thank you Dr. Pascal for this wonderful summer.

Thanks to Dr. Pascal for allowing me to share my experience on his blog and I hope you enjoy the read!
An “Egg-cellent” Journey to Investigate Carotid Artery Stenosis in Cambridge, Ontario…
Last Wednesday, my ROP students Kiersten and Indranil, and UofT medical student Eli Lechtman had the opportunity to interview the legendary (see here) Dr. Kim Tysdale – a general practitioner in Cambridge, Ontario.
Why do you ask? Well each year 50,000 Canadians suffer from a stroke with 26% due to carotid artery disease. Carotid artery stenosis is the narrowing of the carotid arteries due to plaque buildup (see atherosclerosis). These plaques can then rupture and create blood clots that travel up to the brain. In turn, these blood clots then get stuck in the brain’s smaller blood vessels, causing a stroke. So plaque = bad and ruptured plaque = worse!
What if we had a clue as to which plaque may rupture? Well, in turns out that the presence of intraplaque hemorrhage (IPH) can help us predict just that! IPH is bleeding within the plaques, which causes them to become more vulnerable (see vulnerable plaque). There is a 6 times greater risk of stroke in people with IPH! And…. a new medical imaging technique called MRIPH imaging allows for visualization of IPH. MRIPH is similar to traditional MRI but highlights the artery walls and looks at the arterial plaques.
While in Cambridge, Kiersten, Indranil, and Eli presented Dr. Tysdale with an overview of medical imaging techniques for the assessment of carotid artery stenosis with an emphasis on the new MRIPH technique. Informing physicians like Dr. Tysdale which of his patients are more at risk of having vulnerable plaques (by providing information on IPH) could result in patients receiving more appropriate and timely treatment – thereby reducing the number of strokes!
BTW, we had Dr Tysdale at “hello” (not sure what I am referring to? See here).
So what up with the eggs? Kiersten, Indranil, and Eli also had the chance to tour Dr. Tysdale’s beautiful country house and meet his lovely wife (and nurse!), Eva, who sent everyone home with fresh chicken eggs! Awesome.
Thank you Dr Tysdale for being such a great sport!
Here is their infographic of the trip (great job gang!). Enjoy!

MiCUP… Runneth Over?
An interesting quotation from the Hebrew bible. Basically it means that I have sufficient for my needs and I am good with that. So, where am I going with this you ask? Well, let me introduce you to my program MiCUP – Medical imaging Collaborative Undergraduate Program.
The goal of the program is to bring together students from the faculty of Arts and Sciences and my faculty (Medicine) to learn about medical research in the world of medical imaging. I have a sprinkling of students every term from various programs such as Research Opportunity Program, Independent Studies, Youth Study Program, and MiVIP. It is only a modest number of students BUT provides ample brain power to get some really cool research done. My cup certainly runneth over.
Have a look below at the timelines from my two recent ROP students.
Great work Kevin and Sylvia!!!
See you in the blogosphere,
Pascal Tyrrell
