Mariah Carey recently announced that her husband, "America's Got Talent" host Nick Cannon, is hospitalized in Aspen, Colo., with mild kidney failure. Carey tweeted this morning: "Please pray for Nick as he's fighting to recover from a mild kidney failure. #mybraveman"…Acute kidney injury occurs when the kidneys stop functioning properly, thereby allowing fluids, waste and electrolytes to store up in the body, according to the Mayo Clinic. It can be diagnosed by an elevated level of serum creatinine, a blood measurement.
