This study is exploring certain aspects of the blood and brain to determine how a person may recover from COVID-19. In addition, this study will examine how the different aspects of COVID-19 may affect how a person thinks or feels.
This randomized controlled trial will enrol patients with acute severe brain injury who pass a spontaneous breathing trial but have decreased level of consciousness. It will directly compare (1) prompt extubation vs. (2) prompt tracheostomy vs. (3) usual care, with extubation or tracheostomy timed according to physicians' discretion. The primary outcome will be ICU free days (days spent alive and outside an ICU).
The purpose of the main study is to investigate adverse drug reactions from multiple sclerosis (MS) disease modifying drugs by understanding the genetic factors that contribute to their cause.
The sub-study investigates how the MS disease modifying drugs affect microbes in the gut and how human DNA affects the changes in the gut microbes following drug treatment. We are also interested in how gut microbes might relate to progressive MS.
