Stem cells are usually thought of as the building blocks of the body – able to give rise to all our cells and organs. But Dr. Lauralyn McIntyre, Dr. Duncan Stewart, Dr. Dean Fergusson and their colleagues are testing the idea that certain stem cells may also be able to help control the body’s immune system to reduce injury and promote healing, while improving its ability to fight infection. They recently published the results of the world’s first clinical trial of mesenchymal stem cell therapy for septic shock, a life-threatening condition that can occur when an infection spreads throughout the body. The trial involved thirty patients, nine of whom were treated with up to 250 million mesenchymal stem cells. No serious adverse events occurred. A randomized, multi-site trial is expected to start next year, with the power to evaluate benefits as well as risks. Charles Berniqué, a 73-year-old grandfather from Hawkesbury, Ontario, recently survived a deadly infection requiring prolon

Health care providers now have a new tool to help decide whether a liver surgery patient needs a blood transfusion, thanks to a study led by Drs. Guillaume Martel and Dean Fergusson. Liver surgery often involves major bleeding, and about one in four patients will receive a transfusion. While transfusions can be lifesaving, they also come with small risks such as infections, allergic reactions, cardiovascular effects and possibly worse cancer results after surgery. To develop the tool, a multidisciplinary panel of experts performed a systematic review that looked at 468 scenarios before, during and after liver surgery. 47.4% of the situations were appropriate for transfusion, 28.2% were inappropriate and 24.4% were uncertain. The resulting tool published in Annals of Surgeryuses a number of patient factors to calculate whether a transfusion is appropriate, inappropriate or uncertain. This tool is unique because it can be applied to transfusions given both during and after liver surger

Stem cell therapies based on umbilical cord blood hold significant promise, but few have been scientifically proven. Dr. David Allan was awarded $100,000 from Canadian Blood Services (CBS) to develop policies around the use of cord blood that will protect Canadians from the possible dangers of unproven therapies. His team will create a continuously updating bank of clinical studies that support the use of umbilical cord blood cell therapies, so Canadians can know which treatments are proven and which are still experimental. They will also identify the gaps between what the clinical evidence shows and what the public expects from these therapies. Finally, the team will develop processes that will ensure fair access to banked cord blood for regenerative therapies, and design search algorithms that are compatible with national and international registries.

The Canadian Patient Safety Institute (CPSI) announced a new partnership with Dr. Jeremy Grimshaw and his colleagues at The Ottawa Hospital’s Centre for Implementation Research. They will apply their knowledge of implementation and behavioural science to help increase the success of CPSI’s patient safety programs. The partnership is part of the CPSI’s SHIFT to Safety campaign, which aims to give patients, health care providers and organizations the tools and resources they need to keep patients safe in a health care setting. However, for these programs to work they need patients, health-care providers, managers and policy makers to change their behaviours and the choices they make. Dr. Grimshaw and his team will use implementation and behavioural science to identify strategies to support these individuals to make changes that will improve patient safety, such as increased hand-washing. This involves identifying what behaviour needs to be changed, and finding barriers to that change,

Over 90 percent of these patients were able to stop their asthma medications and remain safely off medication for one year. “It’s impossible to say how many of these patients were originally misdiagnosed with asthma, and how many have asthma that is no longer active,” said lead author of the study Dr. Shawn Aaron, senior scientist and respirologist at The Ottawa Hospital and professor at the University of Ottawa. “What we do know is that they were all able to stop taking medication that they didn’t need – medication that is expensive and can have side effects.” Eighty percent of the participants who did not have asthma had been taking asthma medication, and 35 percent took it daily. The study also found that doctors often did not order the tests needed to confirm an asthma diagnosis. Instead t

Drs. Vicente Corrales-Medina and Girish Dwivedi were awarded $153,000 from the Heart and Stroke Foundation to investigate whether pneumonia can cause inflammation in the arteries of older patients. Their team previously found that after patients over 65 had developed pneumonia, their risk of cardiovascular disease rose two- to four-fold. The biological reason for this is currently unknown. Studies in animal models suggest that pneumonia can increase inflammation of the arteries, which has been linked to a higher risk of heart disease. The research team will further investigate this possibility by comparing the artery inflammation levels in pneumonia patients over age 65 with those of patients who have not had pneumonia. This is one of five Heart and Stroke Foundation grants recently awarded to researchers at The Ottawa Hospital / uOttawa.

What is the most efficient way to answer the most important questions to improve care for cancer patients? Drs. John Hilton, Mark Clemons and Dean Fergusson got a group of Ottawa researchers together to answer this question and came up eight key principles, which form the basis for their Rethinking Clinical Trials (REaCT) Program. As described in the Journal of Oncology Practice, REaCT involves comparing different approved treatment strategies rather than developing new ones. It also involves a streamlined process for obtaining oral (rather than written) patient consent, immediate randomization into treatment groups using a mobile device and simplified data collection. Their first trial, which compares two strategies to prevent chemotherapy-related infections in breast cancer patients, has recruited nearly 150 patients in just over 18 months, at a small fraction of the cost of most cancer clinical trials.

After 54 months, one of The Ottawa Hospital’s largest randomized controlled clinical trials has recruited its final patient – number 2,464. The trial, led by Drs. Mark Walker and Shi Wu Wen, is evaluating the effectiveness of the vitamin folic acid in preventing preeclampsia in pregnant women in five countries. Preeclampsia affects about five per cent of pregnant women worldwide, and is characterized by high blood pressure and leakage of protein into the urine. Preeclampsia is responsible for one-third of all pregnancy-related deaths worldwide. Currently, the only way to cure preeclampsia is to deliver a baby – which often happens well before the due date resulting in preterm births. The results could change medical practice worldwide.

Large clinical trial shows CT scanning does not improve cancer detection in people with unexplained blood clots A large clinical trial led by researchers at The Ottawa Hospital and the University of Ottawa has found that contrary to expectations, a CT scan of the abdomen and pelvis does not improve cancer detection in people with unexplained blood clots in their legs and lungs. The results, published in the June 22nd edition of the New England Journal of Medicine, are expected to improve patient care and reduce screening costs around the world. More than 500,000 Canadians and Americans are diagnosed with blood clots in the lungs and legs each year (called venous thromboembolism). In some cases, the clots are caused by trauma, surgery prolonged immobility or a known cancer, but in about half of cases, the cause of the blood clots is unknown. “Unexplained blood clots have long been thought of as a possible early warning sign of cancer, with previous studies suggesting that

Drs. Rodney Breau and Luke Lavallée have published a new study in PLOS ONE regarding complications following the removal of the bladder to treat bladder cancer (radical cystectomy). The study found that 55% of patients experienced a post-operative complication following such a surgery, the most common of which was the need for a blood transfusion (38% of patients). It also identified risk factors for experiencing a post-operative complication, which included older age, female gender, pre-operative health status, chronic obstructive pulmonary disease, low serum albumin, radiotherapy, recent transfusion, and length of operation. Radical cystectomy is often the best treatment option for patients with bladder cancer, but the high risk for complications associated with this procedure warrants more studies to improve patient safety. Dr. Breau and his colleagues have previously identified that lysine inhibitors (to prevent bleeding during surgery) are underutilized for patients receiving ra

Drs. Rodney Breau, Alan Tinmouth, Dean Fergusson and Franco Momoli have published a study in Transfusion Medicine Reviews that examines the effectiveness of medications to reduce bleeding during pelvic surgery. Surgery in the pelvic area is inherently difficult and may result in heavy bleeding that requires patients to undergo blood transfusions. The authors assessed the safety and efficacy of a class of medications called lysine analogs. Lysine analogs are commonly used during cardiac surgery and are relatively inexpensive. In the current publication, Breau and colleagues evaluated all of the available evidence evaluating lysine analogs during pelvic surgery. They found that this class of medication seems to be safe for patients, while reducing bleeding and blood transfusion requirements. In a previous study, Dr. Breau’s team showed that lysine analogs are not commonly used during pelvic surgery and they are now leading a multicenter prospective trial to verify the effect of lysine a

Dr. Dawn Stacey has been awarded a four -year grant valued at $680,555 from the Canadian Institutes of Health Research (CIHR) to train health providers in home -care teams across Quebec in shared decision making regarding seniors and their decision to continue living in their home or move to a care facility. This decision is one of the toughest for older Canadians to make. Decisions related to living environments that are informed, shared and supported produce better results. An inter-professional approach to shared decision-making is when seniors and their caregivers collaborate in making decisions with two or more professionals involved in their care. Dr. Stacey plans to assess the program's impact by measuring to what extent seniors say they took part in the decision-making process. She and her team will also look at the option each senior chose, whether they regret their decision, its impact on their quality of life, and how much health-care providers involved their patients in the

Larissa Shamseer, a PhD student working with Dr. David Moher , has published a paper in the British Medical Journal that examines the effectiveness of the peer review process. Although peer reviewing manuscripts has been around for more than 200 years, there is very little hard evidence concerning the effectiveness of the peer review process at improving the reporting in today’s biomedical journals. Ms. Shamseer was part of a team that reviewed 93 articles that had undergone the peer review process. They concluded that peer reviewers failed to detect important deficiencies in the reporting of the methods and results in many randomized trials. Also, the number of changes requested by peer reviewers was relatively small. However, most authors did comply with recommendations they received. Adherence to reporting checklists by journal editors, peer reviewers and authors could improve the reporting of published articles, according to Ms. Shamseer’s paper. Read the full paper. About the O

Dr. Jeremy Grimshaw has been awarded $1 million from the Ontario Ministry of Health and Long-Term Care to study different ways to get people who have suffered a heart attack to continue rehabilitation and take their medication. Previous studies show that, a year after a major heart attack, just 30% to 40% go to rehabilitation and only 50% take their medications properly. The multi-site study will be based out of Women’s College Hospital in Toronto, and Dr. Noah Ivers will co-lead the study along with Dr. Grimshaw. The research will examine the effectiveness of different ways to get heart attack patients to follow their treatment plans. Strategies will include reminder letters, automated phone calls, follow-up phone calls from nurses, and a combination of all three methods to see which is most effective. The cost of each strategy will also be analyzed. About the Ottawa Hospital Research Institute The Ottawa Hospital Research Institute (OHRI) is the research arm of The Ottawa Hospita

Dr.Andrew Seely has published a paper in Critical Care concerning a technique for predicting the successful removal of breathing tubes from people who are on life support. The five-year study involved 721 patients in 12 centres across North America, including Ottawa, Toronto, Vancouver and Cleveland, Ohio. Being able to accurately predict the likelihood that someone on life support will be able to breathe on their own is important as 12% to 15% of these people fail to do so when their breathing tube is removed. Reinserting a breathing tube is extremely stressful on the body and can cause death in severe cases. Dr. Seely hopes to use the findings from the study in his development of technology for use in Intensive Care Units that will measure the respiratory and heart rate variability of patients, and give physicians a better predictor of whether a person is likely to struggle without a breathing tube.
