Vincent Dandenault

Univerity of Montreal

Research Project:

“Application of Bayesian networks to multi-omics data to improve the diagnosis of asthma in preschoolers.”

Vincent Dandenault is a graduate student doing research in the field of computational medicine at CHU Sainte-Justine Hospital in Montreal, Quebec. Coming from a background in software engineering, he is specialized in machine learning and looking to apply his set of skills, knowledge and experience in these complexe and powerful algorithms to the world of respiratory health, more specifically to the research and understanding of preschool asthma.

Currently, doctors do not fully understand the underlying mechanisms of asthma, and they can’t reliably test preschool aged children for asthma. Thus, they do not know which preschoolers with breathing difficulty actually have asthma or not, and who can benefit from available medication and treatments. Accordingly, Vincent’s primary goal as a researcher is to better understand the underlying mechanisms of asthma, and to ultimately link the current different observed phenotypes to different underlying pathways, leading to better diagnosis of preschool asthma, and consequently better patient care. Suffering from respiratory problems himself as a child, he can understand how scary and worrying asthma can be, notably asthma attacks and exacerbation, for patients and their loved ones. Ultimately, Vincent’s goal is to use machine learning to shed light on these problems.

Treating Asthma by Integrating Learning Algorithms with Omics Research: Moving toward Automated High-Dimensional Endotyping in Children (TAILOR-MADE)

Asthma is a disease of the lung and is common in kids. Asthma symptoms happen when your airways tighten and swell, causing breathing problems like wheezing.  Another word for swelling is inflammation. Sometimes the inflammation could make it very hard to breathe. This is an asthma ‘attack.’ Asthma attacks are more common in preschoolers than other age groups. When asthma symptoms happen, kids need to visit their doctor for a diagnosis and treatment. Sometimes, doctors cannot confirm asthma in young children because they are unable to perform the test needed for a diagnosis. On the other hand, they can try to treat the inflammation that happens with asthma symptoms by prescribing medicines that you inhale. A major problem is that these medicines do not always work. This led scientists to try to understand why that is.

Scientists now think that asthma is not just one disease, but many different diseases that need different medicines. We still do not know much about these different diseases in children who have asthma symptoms. But we think that we can understand a lot more about the disease processes by collecting different biological samples, like blood, breath, or saliva, from children and then analyzing them with new technologies. The samples contain signals that can help us identify the different disease processes. These signals are also called biomarkers. There are millions of biomarkers in the body and this large amount of data makes it challenging to find which biomarker might be important for the disease process. We now have advanced computer tools, called machine learning, that can help us with this ‘big data’ problem.

The goal of my research is to use machine learning to discover important biomarkers of different disease processes in children with asthma symptoms that can help doctors predict whether asthma medicines will work well in them. To do this, my research team will analyze clinical and biological biomarker data from 282 preschoolers and children with asthma symptoms. We expect the results to help doctors identify which children will benefit from treatment or help develop new medicines for those that will not benefit.

Asthma phenotypes, risk factors and the implications for future management in Canadian children

Asthma is the most common chronic disease of childhood, usually beginning in preschool and lasting through adulthood. In preschool, defining asthma is challenging for two reasons – a lack of objective measures along with a heavy reliance on a non-specific symptom of wheeze and a diverse clinical course reflected by remission and relapse. Earlier research tells us that asthma is likely caused by several different pathways that are influenced by genetic and environmental risk factors. These pathways are defined by their clinical traits during their later life, e.g. persistent wheeze, transient wheeze. We believe these disparate pathways reflect different types of asthma (asthma phenotypes)  and we will try to move towards a more objective method to identify these pathways in early life. To do this, we will use two research data platforms, namely the CHILD Cohort Study and the Canadian Urban Environmental Health Research Consortium (CANUE). The first aim is to define distinct asthma phenotypes by applying data-driven methods to asthma traits (e.g. wheeze, atopy, body mass index), and to determine whether these phenotypes are different in males and females. The second aim is to determine key early-life risk genetic and environmental factors associated with these distinct phenotypes. This study will address several knowledge gaps in our understanding of early life asthma phenotypes as well as the influences of genetic and environmental exposures on these patient phenotypes. It will also promote future studies to help us better understand the underlying disease mechanism and provide important evidence to develop disease prevention and management strategies for families, clinicians, and policymakers.

2021 Graduate Student Research Award winner Caren Cao

2021 Recipient, Bastable-Potts Graduate Student Research Award

Biography: Caren (Xiaoshu) Cao completed her HBSc and MASc as top students at University of Toronto, and is currently pursuing her PhD in Biomedical Engineering at University of Toronto. Her thesis work focuses on the discovery and treatment of novel physiological mechanisms of asthma worsening and its connection to obstructive sleep apnea, using advanced biomedical technology. Her previous work funded by Asthma Canada was recently published in the American Journal of Respiratory and Critical Care Medicine. She also has another publication related to aspects of her PhD work and four publications arising from her previous Masters thesis. She has already won four awards during the course of her PhD, including first prize in a national research competition. She has presented her research at six international and national conferences to date, including European Respiratory Society and World Sleep Congress. Caren’s work is highly innovative, focusing on understudied aspects of physiology at a time when asthma research has been focused primarily on pharmacological treatments. Caren hopes that this program of research could define an important new direction for the monitoring and treatment of asthma. If successful, it will also build new capacity for Canadian research in the application of new biomedical technologies for asthma management. 

Research Project: Understanding the link between obstructive sleep apnea (OSA) and asthma

Asthma and obstructive sleep apnea (OSA) are very common breathing disorders that cause disability and poor quality of life. Asthma and OSA often occur together but the reason for this remains unclear. Our research group has established that body fluid moving from the legs to the upper body during sleep is a cause of OSA. In previous studies, my colleagues showed that squeezing fluid out of the legs into the chest in asthmatics worsens their asthma by causing narrowing of their small airways. Therefore, I propose to investigate the possibility that OSA worsens asthma by increasing chest fluid volume overnight. Results from my previous research project funded by Asthma Canada showed that mimicking OSA draws fluid into the chest and increases small airway narrowing. This result provides strong evidence that one link between the two disorders is probably fluid moving into the chest. The second study will determine if asthma patients with OSA have more fluid moving into the chest and greater small airways narrowing overnight. The outcome of my research could lead to a novel approach to treating some cases of asthma: i.e. by diagnosing and treating co-existing OSA. Therefore, patients with poor asthma control may benefit from OSA screening. Ultimately, should my hypotheses prove correct, clinical trials could be designed to determine whether treatment of OSA can improve patient-centred outcomes over long time periods and reduce healthcare utilization.

Andrew Kouri

2021 Recipient, Bastable-Potts Graduate Student Research Award

Biography: Andrew Kouri is a respirologist and PhD student at the University of Toronto with an interest in airways diseases and how technology can be leveraged to improve the care of patients with asthma and COPD. His research investigates how mobile health tools are developed and used in older adults with airways disease, applying a health equity lens to the growing field of respiratory digital health. His academic goal is to become an  independent clinician-scientist and to study how best to deliver virtual and digital health technology to patients with asthma and COPD, including populations who are currently underserved by these promising health innovations. Outside of the hospital he loves cycling and running, hiking with his wife and lazy pug (and hopefully soon with his 2 month old newborn son!), and dreaming of future travels!

Research Project: My PhD research project is focused on trying to develop a deeper understanding of how mobile digital health tools like smartphone apps and electronic inhalers and other devices can be best used to help treat patients with asthma. I am particularly interested in how older patients use these type of tools, and how we can better design and implement mobile health technology in older patients with asthma. In order to accomplish this, I have studied specifically how older age influenced the use and engagement with a primary care mobile health asthma questionnaire developed at St. Michael’s Hospital by Dr. Samir Gupta, I am completing a literature review across all published studies of asthma mobile health to see how the needs of older adults have been considered (or not considered), and I am running a qualitative study where I am interviewing older adults with asthma in order to better understand their needs and unique perspectives when it comes to using mobile health technology.

Research Project: Prenatal air pollution exposure is associated with an increased risk of childhood asthma. While the mechanisms underlying this association remain unclear, researchers believe that environmental exposures become biologically embedded in epigenetic patterns during critical developmental periods. These altered patterns are thought to “reprogram” cell function, and ultimately influence health outcome. This research project will identify epigenetic patterns associated with prenatal air pollution exposure at birth and examine whether these patterns persist into childhood. Epigenetic changes will be correlated with childhood asthma to determine their role in asthma risk. However, we are most interested in the association between persistent epigenetics changes and asthma, as persistent epigenetics changes are more likely to influence health outcome than transient ones. This analysis will provide insight into molecular pathways that are altered by prenatal air pollution exposure and contribute to asthma. Additionally, as we believe air pollution induces epigenetics changes through increased oxidative stress, this research will investigate if maternal diets higher in antioxidants (like vitamin C) can mitigate the effect of prenatal air pollution exposure on child epigenetic patterns. Together, this research will help clarify how prenatal air pollution exposure predisposes children to asthma and begin identifying preventative measures.
