Specialized occupational therapy tools at the clinic were replaced by scavenged substitutes: buttons, small glasses, pieces of wood or pipe now help patients relearn activities of daily living.

The Vatican said on Friday that the Pope's condition is improving, but one official said he may have to "relearn to speak" following his prolonged use of high-flow oxygen therapy.
