Dr. Yuen is a kidney doctor and scientist at St. Michael’s Hospital in Toronto. His major research interest is the study of kidney scarring, a process that is ultimately responsible for nearly all cases of kidney failure.

There is currently no good test to detect this scarring. The best test available is a needle biopsy, which is associated with significant bleeding risks, requires a day of monitoring, and can not sample and analyze the entire kidney. A new type of MRI called “MR elastography” has been proven to accurately measure scarring in the liver, but not yet in the kidney. It does not need any injections, can be done in 30 minutes, and may be able to measure scar throughout the entire kidney without needles.

The Physicians’ Services Incorporated Foundation is supporting a research project in which Dr. Yuen and colleagues are testing the potential ability of magnetic resonance imaging (MRI) to measure kidney scarring, comparing it against biopsy analysis. Together with Dr. Anish Kirpalani, a radiologist at St. Michael’s Hospital, and a team of kidney doctors, pathologists, and imaging experts, Dr. Yuen hopes to determine if MRI can measure scar in the transplanted kidneys of people with both normal and abnormal transplant function. This could drastically change how a doctor treats transplant failure.

“The PSI Foundation resident research grant was pivotal in allowing us to study the use of a Daily Goals Checklist in our intensive care unit and learn how this tool could benefit safe patient care, communication, and education. This was the first major peer-reviewed grant funding we have received, and through this project we gained tremendous, first-hand experience conducting rigorous clinical research under the guidance of Dr. Deborah Cook. With the support of the PSI Foundation funding, this project has served as a take-off point for our careers in critical care research.”

In 2012, Drs. Erick Duan and John Centofanti received a Resident Research Grant for $13,000 for their study “ICU Daily Goals Checklist: a mixed methods analysis of effects on communication & patient care.” This project was supervised by Dr. Deborah Cook at McMaster University. Drs. Duan and Centofanti published the results of their study in Critical Care Medicine. They have presented this research in both oral and poster form, including at the 2015 PSI Annual General Meeting, where they won an award for best poster. (Please see citations below.)

Dr. Duan completed medical school and residency at McMaster University. He is finishing fellowship training in Critical Care Medicine and will continue on to the Clinician-Investigator Program, also at McMaster, while beginning a Master’s degree in Health Research Methodology. Dr. Centofanti completed medical school and residency in Anesthesiology at McMaster University. He has begun a Critical Care Medicine fellowship, and will also be completing a Master’s degree in Health Administration at McMaster.

“The PSIF Resident Research Grant was the first project funding that I ever received, and it allowed me to answer a question from my clinical work with people who were incarcerated. Through that project, I learned about prison health research in Canada, and I developed relationships with people working in this field. I am now building on this foundation to develop a program of research focused on improving the health and health care of people who are incarcerated in Canada.”

In 2008, Dr. Fiona Kouyoumdjian received a Resident Research Grant for $18,000 for her study “The prevalence of gonorrhoea and chlamydia in male inmates in a provincial correctional facility in Ontario.” This project was supervised by Dr. Cheryl Main at McMaster University. Dr. Kouyoumdjian has published three papers in peer-reviewed journals based on this project in the International Journal of STD & AIDS and the Canadian Journal of Public Health. The third is in press (citation: F. G. Kouyoumdjian, L. M. Calzavara, L. Kiefer, C. Main, S.J. Bondy. Drug use prior to incarceration and associated socio-behavioural factors in males in a provincial correctional facility in Ontario, Canada. Canadian Journal of Public Health. In press). Dr. Kouyoumdjian presented her research as a poster presentation at the 2014 PSI Annual General Meeting.

Dr. Kouyoumdjian completed medical school at Dalhousie University, a Master of Public Health at the Johns Hopkins Bloomberg School of Public Health, and residency in Public Health and Preventive Medicine and a PhD in Epidemiology at the Dalla Lana School of Public Health at the University of Toronto. She is currently a Postdoctoral Fellow at the Centre for Research on Inner City Health at St. Michael’s Hospital in Toronto, with Dr. Stephen Hwang as her supervisor, and she works as a Family Physician at a provincial correctional facility. She has a CIHR Fellowship from 2013 to 2016.

How did the PSI Funding Help with the Study?

The funding via the PSI Foundation enabled groundbreaking work to provide evidence that glucose can be controlled in severely-burned patients via novel perturbations and that this modulation of glucose is beneficial in terms of outcomes after a burn injury. These results are ultimately leading to an ongoing large prospective clinical trial which hopefully will confirm the benefit of the perturbation.

Description:

PSI Foundation funded Dr. Marc Jeschke of Sunnybrook Health Sciences Centre in Toronto for his study Glucose control in severely burned patients: mechanisms and therapeutic potential. In 2010, PSI approved $165,000 for his 2 year study.

Dr. Jeschke is a Professor in the Department of Surgery and the Department of Immunology at the University of Toronto. He is also the Director of the Ross Tilley Burn Centre and Senior Scientist at the Sunnybrook Research Institute.

Dr. Jeschke has had several papers resulting from this research, including publications in Lancet and the Annals of Surgery.

“The PSI funding was essential in allowing us to initiate our work on semen proteomics: this understanding of semen proteins was subsequently used as the basis for the work we have done to identify novel semen biomarkers for different types of infertility, prostate cancer and chronic pelvic pain in men. This resulting work has now been supported by CIHR, CCSRI, The Canadian Urology Association, bioMerieux Laboratory, LabCorp USA and MaRS Innovation. None of this would have been possible without that initial support from PSI.”

PSI Foundation funded Dr. Keith Jarvi of Mount Sinai Hospital in Toronto for his study Use of Seminal Fluid Protein Patterns as Biomarkers for Diseases in the Male Reproductive Tract: Prediction of Spermatogenesis in Men with Azoospermia. In 2007, PSI approved $158,000 for his 2 year study.

Dr. Jarvi is a Professor in the Department of Surgery at the University of Toronto. He is also the Director of the Murray Koffler Urologic Wellness Centre and Head of Urology at Mount Sinai Hospital.

Dr. Jarvi has had several papers resulting from this research, with the most recent being published in Science Translational Medicine. This study has also been featured in media including the Toronto Star, the Globe and Mail, and BBC Health News.
