ROME (AP) — Pope Francis remained in critical condition Monday but showed slight improvement in laboratory tests and resumed some work, the Vatican said, including calling a parish in Gaza City that he has kept in touch with since the war there began.

On his tenth day in Rome’s Gemelli Hospital for treatment of a complex respiratory infection and bilateral pneumonia, Pope Francis remains in critical condition but his lab tests have shown a slight improvement,

Pope Francis is being treated for double pneumonia and recent blood tests also revealed "mild renal insufficiency."

The Vatican says Pope Francis remains in critical condition and blood tests show early kidney failure but he remains alert and “well-oriented.”

Pope Francis, in critical condition battling double pneumonia, had a "good" night in hospital, slept and is resting, the Vatican said on Monday. The pope was admitted to Rome's Gemelli hospital on February 14 after having trouble breathing for several days and subsequently had pneumonia diagnosed in both lungs.

Pope Francis woke up and was continuing his therapies Monday after a quiet night, on the 10th day of his hospitalization for a complex lung infection that has provoked the early stages of kidney insufficiency,
