Today we are very fortunate to welcome Franco Rafael D’Alessio MD, assistant professor of medicine at the Johns Hopkins University School of Medicine with a specialty on critical care medicine. If there is one thing that Dr. D’allasio knows, it is sepsis. In fact over the last several years he has published numerous papers on the immunology of lung disease, focusing on T cell use, macrophage response, and the changes to inflammation that occur with aging. Today he focuses his brilliance to a 45 minute talk that is essential if you ever want to truly understand what sepsis does to your patients!
