Congratulations to all of the successful applicants!

Projects through Lawson Health Research Institute: 

Karen Bosma, and Laurent Brochard: “Proportional Assist Ventilation for Minimizing the Duration of Mechanical Ventilation: The PROMIZING Study.”

Critically ill patients frequently require the life-sustaining technology of mechanical ventilation, but prolonged use can place patients at risk for long-term functional impairment and increased mortality, and is also costly to the health care system.

The PROMIZING Study is an international, multi-centre randomized clinical trial that will identify ways to reduce the duration of mechanical ventilation for patients at greatest risk and to determine whether a novel mode of ventilation developed in Canada could replace the standard of care.

“It is vital that Canada continue to invest in high impact, hospital-based research such as the PROMIZING study which enable researchers to develop and test treatments, technologies, and procedures that will improve clinically relevant, patient-important outcomes while also improving the efficiency of our healthcare system.” – Dr. Karen Bosma

Diane Bryant, and Alan Getgood: “Anterior Cruciate Ligament Reconstruction using Bone Patellar Bone or Quad Tendon Autograft with or without Lateral Extra Articular Tenodesis in Individuals who are at High Risk of Graft Failure (STABILITY II)”

Anterior cruciate ligament reconstruction (ACLR) is complicated by high failure rates in young active individuals, which is associated with worse outcomes and higher rates of osteoarthritis. 

Currently, there are different types of grafts being used to rebuild a torn ACL. There is a need to evaluate whether one method is better at reducing failure, minimizing complications and creating better outcomes in terms of functional performance. This study will determine the best graft choice for young patients at risk of ACLR failure which will ultimately lead to positive effects on activity and quality of life. 

Patrick Luke and Rabindra Bhattacharjee: “Therapeutic potential of bloodless oxygenated perfusion of donor kidneys for prolonged storage and protection for transplantation.”

Kidney failure among Canadians has tripled over the last 20 years. Transplantation improves the quality of life and survival of patients at a much lower cost than dialysis. However, only 40 per cent of patients receive functional kidneys due to lack of living organ donors. 

To increase the number of kidneys available for transplantation, surgeons are accepting orgrans from deceased donors. Currently, during storage, the organs can suffer injuries from a lack of oxygen as well as cold temperatures and the conditions are not conducive to use drugs that can prevent damage. 

The study is looking at the effects of a bloodless oxygen carrying perfusion liquid that will allow the storage of human donor kidneys for long periods of time at room temperature, and will also evaluate if certain drugs can maximize the preservation of these organs. 

“Hospital-based research institutes are uniquely positioned to conduct patient-centred research. Investment through CIHR supports the physicians and researchers who are committed to improving treatments for patients at the front line of care.” – Dr. Patrick Luke

Emil Schemitsch: “The DECIPHER Study: DEterminants of Function and Clinically Important outcomes in Proximal Humerus Fractures in the Elder Population: A National CohoRt.”

Shoulder fractures are becoming increasingly common for older adults and cause considerable limitations and impacts for their daily life. While different approaches are taken to treat shoulder fractures, there is a lack of knowledge and evidence to show which of those methods are the most effective and for which patients.

The DECIPHER study will seek to answer important questions about which treatment and rehabilitation strategies are best for different patients, strengthening the clinical strategy for managing these difficult and prevalent injuries. It will also provide an economic analysis to understand the impact for healthcare system costs.

“Such an analysis has the potential to significantly affect patient care and Canadian practice patterns, as well as inform the development of future pivotal clinical trials. DECIPHER will have an important impact on patient care, health system costs and future research directions locally, nationally and internationally.” - Dr. Emil Schemitsch.

Last week, the Honourable Kirsty Duncan, Minister of Science and Sport, announced an unprecedented investment of more than $588 million through the Natural Sciences and Engineering Research Council of Canada’s (NSERC) Discovery Grants program. 

The successful applications in London include 12 projects funded for Lawson Health Research Institute scientists, through Western University. In total, they will receive $2.3 million in funding over five years. 

“The funding demonstrates our strong and enduring commitment to science and researchers. Since taking office, our government has worked hard to bring science and research back to their rightful place and this historic investment in the discoveries of tomorrow is just one example of how we are achieving this goal,” says The Honourable Kirsty Duncan, Minister of Science and Sport. 

Across Canada, this funding will go to more than 4,850 researchers and students as they pursue their world-leading discovery work. It also includes support for nearly 500 early-career researchers who will bring a diversity of new voices and new insights to their fields.

Local research highlights 

Dr. Jeffrey Carson is exploring the role of photoacoustic imaging as a method for detecting breast cancer. Currently, during the procedure the breast must be submerged in a tank of water to enhance the transmission of photoacoustic waves from the breast to the sensors. 

“The water tank is cumbersome and impractical,” notes Dr. Carson. “Our goal is to eliminate the need for the water tank by detecting the photoacoustic waves through the air without making contact with the breast.” Their hope is that the project leads to the development of a non-contact photoacoustic scanner offering women the opportunity to sit or stand comfortably during breast imaging. “This simple improvement could greatly accelerate the adoption of photoacoustic imaging for breast cancer screening.”

Dr. Carson adds that funding like this provides graduate student trainees opportunities to develop knowledge and skills in engineering, mathematics, and biophysics. “They bring innovative new ideas to the Canadian medical device industry through employment and entrepreneurship.”

Dr. Rajnikant Patel is developing advanced robotic and intelligent systems for the next generation of systems and devices for minimally invasive surgery and therapy. These reduce trauma and costs while enhancing efficiency and reliability. 

“For us, this funding opportunity is unique because it supports a program of research rather than a project,” says Dr. Patel. “We can explore new areas and directions that will lead to research projects and medical applications. A program that investigates novel robotic and AI technologies fits well with NSERC’s mandate.”

Dr. Gregor Reid is leading a revolutionary project that could save the world’s honeys bees, insects that are vital to human survival. 

The intent is to develop an understanding of how lactobacilli strains can counter the most widely used pesticides that are wiping out nature's critically important pollinators. The lactobacilli appear to potentially degrade some of these toxic chemicals and improve the ability of honey bees to fight off early death.   

“NSERC funding gives ideas like this a chance and even though the funding amount is relatively small, it allows graduate students to apply for their own awards and work on the project,” explains Dr. Reid. Students Brendan Daisley and Johnny Chmiel have been awarded NSERC scholarships to work on this important research.

Dr. Xiugen Zheng’s project is investigating the role of circular RNA AEBP in the development and function of dendritic cells which are very important immune cells in the immune system. This will provide insights into new molecular and gene regulators, and their impact on the immune system and overall health. 

“NSERC research funding greatly supports us to study the basic scientific questions that are critical for better understanding health problems and developing treatment for diseases,” says Dr. Zheng.

Dr. Rudolf Veldhuizen’s laboratory aims to understand how surfactant performs its function at a molecular and biophysical level. Pulmonary surfactant is a material in the lung that allows people and other mammals to breath with minimal effort. You can see this in babies who are born prematurely and have trouble breathing due to the lack of surfactant. 

“Previous work has established a generalized model of how surfactant improves lung function under standardized conditions. This, however, does not explain how surfactant functions in extreme conditions,” says Dr. Veldhuizen. “By exploring conditions in comparative, mechanistic studies we will be able to establish a more universal understanding of surfactant function.” 

This funded work provides a foundation for clinically relevant studies to further explore the role of alterations to surfactant in lung injuries and the opportunities for therapeutic interventions.

Dr. Shou Li is developing state-of-the-art machine learning system able to analyze huge amounts of clinical data and provide human level intelligent analysis. This work will enable the prediction of disease onset, progression and prognosis. “It is added value that will lead to more effective and efficient health care,” explains Dr. Li. 

He adds that this funding is supporting a multi-disciplinary research program that combines the strength of multiple teams. “We will look at both the fundamental side of machine learning systems and clinical applications. In this way, we connect basic science with clinical science.”
