As of 11 a.m. Monday, Aug. 26, both Maria Teresa and Maria de Jesus Quiej Alvarez remain in serious condition with stable vital signs in the Pediatric Intensive Care Unit at UCLA’s Mattel Children’s Hospital. Doctors anticipate a gradual, slow healing process for both girls and remain cautiously optimistic about their long-term prospects for recovery. The one-year old Guatemalan twins, who were born conjoined at the head, were separated at UCLA on Aug. 6 in a nearly 23-hour surgery.
