Dr. Christopher Wallis: Does Testosterone Replacement Therapy Increase Risk of Cardiovascular Disease?

The PSIF Resident Research Grant gave me the opportunity to investigate an issue of interest both to me and the medical community. Through this support, I was able to develop an analysis which goes into greater detail than previously available. In doing so, I worked collaboratively with many researchers who would otherwise not have interacted. While the true importance of this work remains to be seen, this opportunity has greatly enriched my research experience.” – Dr. Christopher Wallis

In 2014, a controversial article published in the Journal of the American Medical Association suggested that testosterone replacement therapy increases cardiovascular risk. Dr. Christopher Wallis of the University of Toronto knew he had access to a wealth of information available in Canadian healthcare databases to address this controversy. Through the support of PSI Foundation, Dr. Wallis was awarded a Resident Research Grant for $17,500 in 2015 in order to further investigate this question in his study titled “A population-based cohort study assessing cardiovascular and oncologic events associated with testosterone replacement therapy.”

Examining all patients over the age of 65 treated with testosterone and untreated, matched patients, Dr. Wallis and colleagues were able to conclude that testosterone treatment over the long-term is associated with a decreased risk of death and cardiovascular events.

Dr. Wallis has now published these results in the Lancet Diabetes & Endocrinology and has shared this information with fellow doctors at international medical meetings and with the public through radio, print and online interviews in Canada and the United States.

While there are limitations to conclusions which can be drawn from these data, this represents an important step in our understanding as well as reassurance to patients receiving and physicians prescribing testosterone. The authors hope that these results will provide the impetus for further research understanding the mechanisms of testosterone’s effect on the cardiovascular system.

Dr. Christine Lee: A Fresh Take on Poop

“Our family wants to thank you for saving the life of our one-hundred-year-old mother by treating her with a fecal transplant. Before this amazing cure, she suffered for seven months with recurring bouts of c-difficile and her health was rapidly deteriorating. She completely recovered from this debilitating disease within 24 hours of the treatment in January.” – Laurie and Jay Cashmore

When you think of poop, does lifesaving come to mind? In 2013, Dr. Christine Lee from McMaster University was awarded with $169,000 for her clinical research study “A prospective randomized double-blind trial of fresh versus frozen-and-thawed human biotherapy for recurrent Clostridium difficile infection.”

Clostridium difficile infection (CDI) occurs when the colon is stripped of good bacteria, typically due to patients taking antibiotics. The use of fresh fecal microbiota transplantation has been the common practice for treatment for recurrent CDI; however, problems related to time involved for screening process and the short window of opportunity to use the specimen have posed as a challenge.

Dr. Lee is overcoming these challenges with her research that proves the feasibility of frozen fecal versus fresh fecal in several areas:

Emotionally, there is a restoration of health and quality of life for many patients, as well as their family members who are the ones caring for the patients.

Economically, the financial burden is lifted for patients and families, as there is a high cost associated with prolonged stays and long-term use of medication (up to $30,000).

Within the healthcare industry, significant reduction in overall length of hospital stay not only minimizes the risk of transmission to other patients, but also, reduces costs. For example, in treating 150 patients over a span of 1.5 years there was a financial savings of $3.3 million.

Next steps are to offer Lyophilized, which is freeze-and-dried stool that can be sent anywhere, making it available more widely.

2015 PSI Graham Farquharson Knowledge Translation Fellow – Dr. John L Sievenpiper

“Effective knowledge translation is integral to the practice of medicine and public health. Traditional “bench-to-bedside” translational research has involved taking discoveries from the basic sciences and translating them into clinical applications. Another equally important type of knowledge translation takes these applications from the bedside to best practices, synthesizing the evidence on important clinical questions and translating the knowledge into clinical practice guidelines and public health policy. The PSI Graham Farquharson Knowledge Translation Fellowship will allow me to apply this model to the big questions in clinical nutrition and chronic disease prevention.”

The PSI Foundation is pleased to announce Dr. John L Sievenpiper of the University of Toronto and St. Michael’s Hospital as the 2015 PSI Graham Farquharson KT Fellow. This Fellowship — valued at $150,000 per year for two years — is intended to protect a new, promising clinician’s research time, allowing the Fellow to undertake high impact translational research.

The Fellowship will allow Dr. Sievenpiper to conduct translational research to address the important questions confronting nutrition guidelines committees. There has been a recent move away from the more traditional nutrient-centric approaches (“low-fat”, “low-carb”, “high protein”) to more food and dietary pattern-based approaches, a change Dr. Sievenpiper helped to initiate and steer in the Canadian Diabetes Association 2013 Clinical Practice Guidelines for Nutrition Therapy. Coming out of this process, his work will use systematic reviews and meta-analyses to synthesize and translate the role of various food and dietary pattern-based approaches in cardiometabolic health. This work will improve health outcomes by informing clinical practice guidelines and public health policy, stimulating industry innovation and identifying gaps for future clinical investigation.

Dr. Sievenpiper completed his MSc, PhD and Postdoctoral Fellowship training in the Department of Nutritional Sciences, Faculty of Medicine, University of Toronto. He completed his MD at St. Matthew’s University, School of Medicine followed by Residency training in Medical Biochemistry at McMaster University. Dr. Sievenpiper is an Associate Professor in the Department of Nutritional Sciences, Faculty of Medicine, University of Toronto. He is also a Scientist in the La Ka Shing Knowledge Institute, Knowledge Synthesis Lead of the Toronto 3D Knowledge Synthesis and Clinical Trials Unit, and Consultant Physician in the Division of Endocrinology and Metabolism at St. Michael’s Hospital. He has authored over 100 scientific papers and 12 book chapters. He remains directly involved in knowledge translation with appointments to various nutrition guidelines committees including those of the Canadian Diabetes Association, European Association for the Study of Diabetes, and the American Society of Nutrition.

Dr. Darren Yuen: PSI’s First New Investigator Grant Recipient

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.

2014 PSI Graham Farquharson Knowledge Translation Fellow – Dr. Naana Jumah

“The PSI Graham Farquharson Knowledge Translation Fellowship has given me a tremendous opportunity to develop a research program in the non-invasive treatment of uterine fibroids. I want to thank the PSI foundation for supporting translational research and early career clinician scientists.

Taking this technology from bench to beside has the potential to positively impact the lives of women suffering from symptomatic fibroids and it also has the potential to decrease health care costs associated with the treatment of fibroids.”

The PSI Foundation is pleased to announce Dr. Naana Afua Jumah of the Thunder Bay Regional Health Sciences Centre as the 2014 PSI Graham Farquharson KT Fellow. This Fellowship — valued at $150,000 per year for two years — is intended to protect a new, promising clinician’s research time, allowing the Fellow to undertake high impact translational research.

The Fellowship will allow Dr. Jumah to conduct translational research in the treatment of uterine fibroids with magnetic resonance guided focused ultrasound (MRgFUS). In Canada, menorrhagia and fibroids are the leading indication for hysterectomy. MRgFUS is a non-invasive method that could decrease the need for surgery. The Fellowship will allow Dr. Jumah to take this technology from a research platform into clinical practice where it can improve the quality of life of women with symptomatic fibroids, particularly those who live in rural and remote settings.

Dr. Jumah received her B.A.Sc in Chemical Engineering from the University of Toronto, her D.Phil. in Medical Engineering from the University of Oxford as a Rhodes Scholar, her M.D. from Harvard University and completed her residency in Obstetrics and Gynaecology at the University of Toronto.

Dr. Marc Jeschke: Improving Outcomes of Burn Injury

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.

Dr. Keith Jarvi: Improving Men’s Health

“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.
