Professor Myrna Dolovich has been active in aerosol research for the past 40 years. Graduating from McGill University with a degree in electrical engineering, she worked, in the early years of her career, with renowned pulmonary physiologists Drs Joseph Milic-Emili and David Bates to expand our understanding of regional ventilation in the normal and diseased lung using gamma scintigraphic methods.  Similar imaging techniques were applied to establish the methodologies currently used for assessing distribution of inhaled therapeutic aerosols in the lung. At St Joseph’s Hospital and McMaster University, working with Drs M Newhouse, J Sanchis and G Coates, she studied deposition and mucociliary clearance from the lung using these scintigraphic methods, also assessing performance of therapeutic inhalers for delivering drug to the lungs of asthmatics, cystic fibrosis and COPD patients. Development of the Aerochamber™ for patient use was a focus of early research for the St Joseph’s Hospital Aerosol Group. Most recently, newer 3D imaging methods, namely positron emission tomography (PET), have been applied to assess the sites of inflammation in patients as well as mapping deposition patterns of inhaled aerosols in 3D.

Other Activities

Aerosol School, 3-day teaching program with practical laboratory experience in aerosol basics, aerosol measurements and techniques and applications to research and pharmaceutical laboratory and clinical settings was established by Dolovich in 2009 with support from the International Society for Aerosols in Medicine (ISAM). It has become an annual program and is currently scheduled for October 2015.

Myrna has served on the Board of Directors of ISAM and is a member of the Editorial Boards of the Journal of Aerosol Medicine and Pulmonary Drug Delivery and Pediatric Allergy, Asthma and Immunology. She is a member of the Health Canada Scientific Advisory Committee – Respiratory and Allergy Therapies (SAC-RT), joining in 2006. In 2009, she was awarded the ISAM Career Achievement Award for contributions to medical aerosol research.

Research Interests: Research interests involve the in vitro and in vivo characterization of vaccine and medical aerosols from various types of drug delivery systems; use of both 2D and 3D PET imaging modalities to investigate factors which influence the deposition and distribution of aerosolized drugs in the lung. A related interest is the investigation of epithelial cell cilia function and structure utilizing nasal and bronchial cilia obtained from patients with various respiratory diseases. The data provides an assessment of the ability of the lung to clear secretions as well as the effects on this key lung defence mechanism of a variety of traditional and experimental therapies. Cell culture using human bronchial and nasal epithelial primary cells have been established to provide model systems for investigating disease mechanisms.

Social determinants of health and health system design

Neil Johnston and Steve Buist (Investigations Editor, Hamilton Spectator) designed and executed the “Code Red” project between 2007 and 2010. Using health service, education records and socio-economic data, neighbourhoods in the City of Hamilton were profiled for socio-economic and health status and consumption of health services. The Code Red series was published over seven days in the Hamilton Spectator and was designed to stimulate a community debate about variation in health status between neighbourhoods and health system re-design. The series won a National Newspaper award for special projects and was shortlisted for the Michener prize. Johnston and Buist won the 2011 Hillman Prize for journalism fostering social and economic justice.

Research Interests: The role of viral infections in acute exacerbations of asthma and COPD and IPF. Respiratory viral infections are the single most important factor in the genesis of asthma, COPD and possibly IPF (idiopathic pulmonary fibrosis) exacerbations. International comparisons of the determinants and distribution of epidemic cycles of asthma and COPD and the factors responsible for them are the focus of current studies.

Research Interests: determinants of chronic diseases; cardiorespiratory health

Dr. Pugsley is the co-founder of the outpatient Chronic Respiratory Care Program and a founding member of the respiratory medical staff at the inception of the Firestone Chest and Allergy Unit at St. Joseph’s Hospital. He is a graduate of the University of Toronto with a specialty in internal medicine.

He continues to be an integral member of the clinical staff within Firestone and of the medical staff of St. Joseph’s Healthcare Hamilton. Dr. Pugsley was instrumental in establishing the Clinic for Chronic Airway Obstruction. This clinic has improved care for patients with COPD by reducing the incidence of infective exacerbations and hospitalization.

Dr. Malcolm Sears graduated from the University of Otago, Dunedin, New Zealand and was on faculty there until 1990 when he was recruited as the Director of the Firestone Regional Chest and Allergy Unit (the forerunner of the Firestone Institute of Respiratory Health), Director of Respiratory Medicine at St. Joseph’s Healthcare and Professor in the Department of Medicine at McMaster University. In 2002 he stepped down as Clinical Director and became Research Director of the Firestone Institute until 2009.

He is director of the CIHR/AllerGen funded Canadian Healthy Infant Longitudinal Development (CHILD) Study following over 3000 infants from pregnancy to age 5 years.

Dr. Sears has published over 250 peer-reviewed papers and book chapters, together with numerous abstracts. He lectures frequently at national and international scientific meetings, and serves on many asthma advisory boards.

Dr. Sears holds an endowed Astra Zeneca Chair in Respiratory Epidemiology at McMaster University.

Research Interests: Dr. Sears is involved in many studies investigating the epidemiology and natural history of asthma with particular focus on its frequency, risk factors and characteristics in large populations. Of note is an important longitudinal study that he has been conducting for more than 30 years, studying the incidence and impact of asthma in a birth cohort of New Zealand children followed from infancy to adulthood. Other research includes assessment of asthma therapies, and the effects of indoor allergens, viral infections, air pollutants, smoking and hormones in respiratory disease.
