Report from the Chair
Hello everyone! I hope everyone had a chance to take time off and enjoy our beautiful summer! Here is a quick update on what we have been doing since our last newsletter.
As the new school term is starting, we are excited to welcome our new cohort of research trainees, some of whom are highlighted in this newsletter. I look forward to working with all of these new students.
The Alberta's Caring for Diabetes (ABCD) Project activities remain exciting. With recruitment finalized for the ABCD cohort, we are pleased to report the baseline characteristics of participants: the average age was 64 years, 45% were female, and 90% were caucasian, with average diabetes duration of 12 years. Most (88%) reported two or more chronic conditions in addition to diabetes, and 18% screened positive for depressive symptoms. We report on a sub-study of cohort participants in the Project Update featured in this newsletter. With this cohort, we look forward to exploring the multi-dimensional and dynamic nature of diabetes care and complications long term. Additionally, the collected data will contribute to broader scientific literature and help to identify local benchmarks and targets for intervention strategies. This in turn will help to guide policies and resource allocation related to the care and management of adults with type-2 diabetes in Alberta.
With our main interventions (TeamCare and HEALD) complete, we are undertaking economic evaluations for both, which involve linkage of our trial data with administrative data from Alberta Health and Alberta Health Services. Also under the ABCD umbrella, the PROACTIVE study, is looking at the progression of depressive symptoms from hospital discharge to 90 days post discharge. Over 400 patients have been recruited, with one-third having type-2 diabetes. We look forward to reporting more results of these projects in the coming months.
I hope the information in our newsletter is informative, and if you have any questions about our activities, please do not hesitate to contact us. I look forward to updating you in the winter with more on ACHORD's activities.
Examining the role of diet, physical activity, sleep and sedentary behaviours within the ABCD cohort
By Mundt C, Mathe N, Johnson ST
Diabetes self-management includes careful consideration of diet and physical activity. With the aid of guidelines developed by the Canadian Diabetes Association, recommendations for diet and physical activity are conveyed through health professionals in primary care settings. Unfortunately, many people with type 2 diabetes have difficulty meeting these recommendations placing them at greater risk for complications such as heart disease, blindness and amputations. And, only now are we beginning to understand the risks associated with being overly sedentary and the role that sleep plays in the development of diabetes-related complications. The aim of this study is to find out more about how people with diabetes are managing important lifestyle behaviours that are considered modifiable. By doing this, we can figure out why some people with type 2 diabetes develop complications and why others don't. To collect this information we will ask approximately 10% of those people who are already participating in the ABCD cohort (N=200) to wear an accelerometer on their waist during waking hours and then on their wrist during sleep for seven days in a row. During three of those seven days, study participants will write down everything they eat in a diet diary. The information gathered from this study will be linked with information being gathered on other self-care behaviours (from the ongoing ABCD cohort survey) and health care utilization (from linked Alberta Health administrative data). We expect to complete our data collection before November 2014.
Recent Literature from the ACHORD Journal Club (Paper discussed Tuesday, June 3, 2014; Commentary by Karly Achtymichuk)
Rationale for the study After a myocardial infarction (MI), a relatively common and serious complication is deterioration in left ventricular function and subsequent heart failure. It was hypothesized that following an acute MI, the drug metformin may be cardioprotective through limiting the size of the infarct and preventing adverse remodeling of the heart. The objective of this study was to evaluate the effect of metformin on left ventricular function in a population of patients without diabetes who presented with ST-segment elevation myocardial infarction (STEMI).
Summary of the study This study was a prospective, single-center, double-blind, randomized, placebo-controlled trial from the University Medical Center Groningen in the Netherlands through January 1, 2011 to May 26, 2013. Inclusion criteria included: patients with STEMI treated by percutaneous coronary intervention with implantation of at least 1 stent with a diameter of at least 3 mm within 12 hours of symptoms; exclusion criteria included: age <18 years, previous MI, known diabetes, need for coronary artery bypass graft (CABG) surgery, renal dysfunction and contraindications for magnetic resonance imaging (MRI). Patients were randomized to either the experimental group, receiving metformin 500mg twice daily for 4 months, or the placebo group, receiving a visually matched placebo. 380 patients were enrolled, 191 in the experimental group and 189 in the placebo group. The primary outcome was left ventricular ejection fraction, measured by MRI 4 months after the MI. The primary analysis was done by intention-to-treat.
Results 275 of the 380 patients underwent MRI at 4 months; reasons for not undergoing MRI included claustrophobia, contraindications for MRI and CABG surgery. There was no statistically significant difference in left ventricular ejection fraction at 4 months between the 2 groups (53.1%, 95% CI 51.6-54.6% in the metformin group and 54.8%, 95% CI 53.5-56.1% in the placebo group, p-value=0.10). A sensitivity analysis which adjusted for age, sex, baseline NT-proBNP and myocardial blush grade did not change the results. The principal secondary efficacy measure, NT-proBNP concentration at 4 months, did not significantly differ between the 2 groups (median 167ng/L, IQR 65-393ng/L in the metformin group and median 167ng/L, IQR 74-375ng/L in the placebo group, p-value=0.66). Other secondary endpoints, including major adverse cardiac events (MACE), creatinine concentration and glycated hemoglobin were not significantly different between the 2 groups.
Discussion The authors concluded that metformin did not have an effect on left ventricular function at 4 months post MI, and therefore their results do not support the use of metformin in this setting. Overall the study was well-designed and well-run. The original hypothesis had the potential to be a very effective strategy, as metformin is a cheap, available and relatively safe medication. Unfortunately no benefit was shown.
The primary outcome, left ventricular ejection fraction, was measured on patients at 4 months post MI. A baseline measure was not done. Ideally we would have both a baseline measure and a repeat measure at 4 months, allowing us to calculate the change in ejection fraction. This was not done for feasibility reasons. Not having a baseline measure can bias results away from the null; however, in this study there was no difference shown between the groups anyways.
Other questions included whether metformin was administered soon enough after the percutaneous coronary intervention and at a high enough dose. These can be questions for future study.

Dax Rumsey, MD
Training Program: MSc Clinical Epidemiology, School of Public Health, University of Alberta
Hi, my name is Dax G. Rumsey. Born and raised in Torbay, Newfoundland and Labrador, I completed a BSc (Joint Honours) in Biology and Psychology at Memorial University of Newfoundland. I then went on to receive my Doctor of Medicine (M.D.) at Memorial, as well. The next step of my training was a residency in paediatrics at the University of Saskatchewan in Saskatoon. After that, I did a fellowship in paediatric rheumatology at the Hospital for Sick Children in Toronto. I now plan to work part time as a paediatric rheumatologist at the Stollery Children's Hospital in Edmonton. I also plan to work toward my MSc in clinical epidemiology through the School of Public Health at the University of Alberta, starting this September 2014. My main supervisor will be Dr. Dean Eurich.
Throughout medical school and my residencies, I have had the opportunity to care for many patients and their families. These experiences have helped me to appreciate the people behind the diseases that we treat. They have inspired in me a deep desire to help further our collective medical knowledge in any way that I can.
For my thesis, I intend to study outcomes of juvenile idiopathic arthritis (JIA) in Canada using the Research in Arthritis in Canadian Children (ReACCh) database, a large database of prospectively collected data from a national observational study of children with newly diagnosed JIA. There are over 1500 patients enrolled from 16 centers across the country, making it the largest database of longitudinal data on children with JIA. The data has been completely collected and cleaned. There are several important questions to be asked related to modeling of disease outcomes and predictors of outcomes, etc. I look forward to working with Dean and others in the School of Public Health, the University of Alberta, and beyond.
Outside of work, my beautiful wife, Rachel, and I have three wonderful children. As practicing Catholics, God is at the center of our lives. We enjoy spending time together and being active.
Danielle Thiel, BSc
Training Program: MSc Epidemiology School of Public Health, University of Alberta
Danielle grew up in Regina, SK. She graduated from Lakehead University in Thunder Bay, ON in 2014 with a Bachelor of Science in Applied Bio-Molecular Science. During her time at Lakehead, Danielle had the opportunity to become involved in two different research projects, both relating to environmental microbiology. Working in the lab sparked Danielle's interest in research as a potential career option. Danielle also took courses relating to public health, and became interested in the population-level approach to studying diseases. She decided to step away from bench science, and pursue a Master of Science degree in Epidemiology at the University of Alberta. Danielle is fortunate to train under the supervision of Dr. Jeff Johnson and is excited to work with the ACHORD group. Her research will be around health outcomes in diabetes populations, focusing on lifestyle factors.
Danielle is also an avid long distance runner, and is a member of the U of A cross country and track and field teams. In her spare time, she enjoys camping, downhill skiing and spending time at the cottage.
