...Elizabeth Beale; Jay Zhu; Howard Belzberg Background: Mortality in the intensive care unit (ICU) rises with age, a high basal serum cortisol and a small response to adrenocorticotropin (ACTH) stimulation. Even slight impairment of the adrenal response during severe illness can be lethal. Objectives...
