With Pope Francis entering his fourth week in hospital, those working in the Apostolic Palace are grappling with the continuing uncertainty over the pope’s health. The same is true for everyone in the Vatican.

Francis, who is known to work himself to exhaustion, has continued to work from hospital. On Saturday, the Vatican announced the appointments of four bishops that would have required his approval. Francis on Saturday also sent a message to an anti-abortion group in Italy which was undertaking a pilgrimage to the Vatican.

Pope Francis "had a tranquil night and woke shortly after 8 a.m.," the Vatican said, coming a day after he made his first public comments since being hospitalized.
