KAREN J. BOSMA, MD, FRCPC, Associate Professor

Dr. Bosma completed her undergraduate work at McMaster University, graduating from the Arts & Science Programme (B. Arts Sc) and subsequently from the McMaster Medical School Program (MD). She then did a residency in Internal Medicine followed by a combined fellowship in Respirology and Critical Care Medicine at Western University. In 2004-2005, Dr. Bosma spent twenty months at the Universita di Torino, Italy doing a Research Fellowship with Professor Marco Ranieri. While in Italy, her research was focused on the relationship between patient-ventilator interaction and sleep quality and she was also involved in studies on acute lung injury in brain-injured patients and the impact of ventilation practices on lung function in potential organ donors.

In 2006, Dr. Bosma started her clinical practice in the Department of Medicine, within the Divisions of Respirology and Critical Care Medicine at the Schulich School of Medicine & Dentistry, Western University. She is an Attending Consultant in the Medical-Surgical Intensive Care Unit, LHSC University Hospital and on the Critical Care Outreach Team.

Dr. Bosma’s research work continues to focus on patient-ventilator interaction, and its impact on sleep quality and weaning from mechanical ventilation. Her work on sleep in the intensive care unit has led her to examine delirium. She was a successful co-applicant for an AMOSO grant which supported a 3 year quality improvement initiative to establish routine delirium screening in the intensive care unit. She was also the site PI for the OSCILLATE study, a multicentre, CIHR-funded randomized controlled trial examining the use of high frequency oscillation for severe, early acute respiratory distress syndrome. Dr. Bosma is an author of three book chapters and ten peer-reviewed publications.

RAYMOND KAO, MD, FRCPC, Professor

I was appointed to the Faulty in September 2003 as Assistant Professor in the Department of Medicine.

In addition to regular commitment to teaching at the undergraduate (medical students) and graduate (residents and fellows) teaching level, I have established a clinical training program for the Canadian Armed Forces’ military physician assistants (PA) to do their clinical phase training at The University of Western Ontario starting in 2004. At the present time the trainees do their rotations in Trauma, Internal Medicine, General Surgery, Orthopedics, Sports Medicine, Urology and Psychiatry. Effective academic year 2007-2008 two new rotations, ENT and Anesthesia, were added to the clinical phase. Now in its fifteenth year at Western University, it has been well received not only by the trainees, the military hierarchy but also by the faculty. The PA clinical training at London enhanced the students’ knowledge and experience in caring of the wounded and the sick in the war zone such as Afghanistan, Iraq and other peacekeeping missions around the world. This program also helped the hospitals affiliated with the Western University to be involved with a new pilot program established by the Ontario Ministry of Health to establish PA in the various hospitals in Ontario.

My research activities consisted of both animal and clinical studies with collaboration in both areas. The animal studies of particular importance related to erythropoietin (rHuEPO) and C-Peptide therapy in septic and hemorrhagic shock. As principal investigator for the initial established rHuEPO in septic mice resulted in an abstract oral presentation in the 9th World Congress of Intensive and Critical Care Medicine followed by its publication in Critical Care journal. The positive results from the septic mice model have prompted new clinical research of the effect of rHuEPO in septic patients in the ICU and this project is in progress. In my lab I have further developed a rHuEPO on hemorrhagic shock rat model in which became an award winning abstract oral presentation at the European Society of Intensive Care Medicine in Berlin. At the present time we are also looking at the effect of C-Peptide in a hemorrhagic shock and resuscitation rat model. I am also involved in large data analysis for the intensive care unit. I published a 24-hour mortality prediction model using logistic regression analysis on 8822 patient observations. At the present our group is performing an external validation of the proposed model using the Critical Care Information System (CCIS) dataset across all Level III ICUs in Ontario.

ALEKSANDRA LELIGDOWICZ, MD, DPhil, FRCPC, Assistant Professor

Dr. Leligdowicz is a clinician scientist in the Department of Medicine in the division of Critical Care Medicine. She completed a medical degree at McGill University and a PhD at Oxford University in human HIV immunology in West Africa. Following residencies in internal medicine (UBC) and adult critical care (UofT), she pursued her interest in immunology and severe infection as a postdoctoral research scholar at the UCSF. Her laboratory at Robarts Research Institute uses cellular and molecular tools to study biological samples from patients admitted to the Intensive Care Unit (ICU) to understand the mechanisms contributing to the regulation of inflammation in severe infection Leligdowicz Lab . The focus of her research is translational biology of immune dysregulation and endothelial injury in early sepsis. The goal of her research is to understand pathology of sepsis and improve the diagnosis and personalize treatment of this complex syndrome.

MARAT SLESSAREV, MD, MSc, FRCPC, Associate Professor

Dr. Marat Slessarev is a clinician-scientist in the Division of Critical Care. He completed his HonBSc, MD, MSc in Physiology and post-graduate training in Internal Medicine at the University of Toronto, followed by fellowship in adult Critical Care Medicine and a PhD in Medical Biophysics at Western University. Dr Slessarev works as a Consultant Intensivist at Critical Care Trauma Centre and Medical Surgical Intensive Care Unit at LHSC and as a Regional Medical Lead (Donation) at Ontario Health (Trillium Gift of Life Network). His research is focused on clinical innovation at the intersection of neurosciences, critical care and organ donation.

He co-leads the following studies/programs of research:

1) NeuPaRT (Neurologic Physiology after Removal of Therapy) program of research seeks to measure when brain activity stops relative to circulatory arrest during the dying process after removal of life support, and interpret these findings from the ethical, legal, and policy lenses to inform the timing of death determination in deceased organ donation;

2) SAVE program of research (https://saveicu.com) that seeks to advance sedation practices in critical care, in part through its flagship SAVE-ICU RCT - a pragmatic open-label multicentre trial comparing the effect of sedation with inhaled (intervention) vs IV (control) sedatives on patient (mortality, quality of life) and health system (duration of ventilation, ICU stay) outcomes in patients with respiratory failure; and

3) ABOVE (Advancing Brain Outcomes in pediatric critically ill patients sedated with Volatile AnEsthestic Agents) - a pilot multicentre RCT assessing if sedation with inhaled anesthetics vs IV sedatives improves neurocognitive outcomes in paediatric patients;

4) Normothermic Regional Perfusion (NRP) – a new intervention that reconditions donor organs after circulatory determination of death but prior to transplantation by selectively recirculating oxygenated blood to abdominal (A-NRP) or thoraco-abdominal (TA-NRP) organs. While practiced in Europe and USA, NRP has not been adopted in Canada due to concerns regarding violation of death determination criteria and potential for donor harm (via resumption of brain blood flow and sentience). Dr Slessarev co-leads provincial interdisciplinary working group that aims to address these challenges and safely implement this method in Ontario.
