Pope Francis is showing slight improvement in his battle against double pneumonia, but his prognosis remains guarded, according to a Wednesday update from the Vatican. A CT scan showed the infection is evolving normally under treatment. The 88-year-old pontiff, who had part of a lung removed as a young man, is still receiving high-flow oxygen but hasn't experienced respiratory crises since Saturday. Blood tests show improvement in low platelet counts and anemia, and kidney insufficiency has receded. He's undergoing respiratory physiotherapy. Despite the improvement, doctors maintain a guarded prognosis. The Pope resumed work from his hospital room, appointing new bishops and approving a new fundraising initiative. Meanwhile, pilgrims gather outside the hospital to offer prayers and well wishes. Cardinal Giovanni Battista Re, dean of the College of Cardinals, led a prayer vigil. Prayers were also offered at the Argentine church in Rome and at the hospital.
