In a statement released by the hospital, Faucette’s wife, Ann, said her husband “knew his time with us was short and this was his last chance to do for others. He never imagined he would survive as long as he did.”The Maryland team last year performed

of a heart from a genetically altered pig into another dying man. David Bennett survived two months before that heart failed, for reasons that aren’t completely clear althoughlater were found inside the organ. Lessons from that first experiment led to changes, including better virus testing, before the second attempt.“Mr. Faucette’s last wish was for us to make the most of what we have learned from our experience,” Dr. Bartley Griffith, the surgeon who led the transplant at the University of Maryland Medical Center, said in a statement.

Attempts at animal-to-human organ transplants — called xenotransplants — have failed for decades, as people’s immune systems immediately destroyed the foreign tissue. Now scientists are trying again using pigs genetically modified to make their organs more humanlike.Faucette, a Navy veteran and father of two from Frederick, Maryland, had been turned down for a traditional heart transplant because of other health problems when he came to the Maryland hospital, out of options and expressing a wish to spend a little more time with his family.

In mid-October, the hospital said Faucette had been able to stand and released video showing him working hard in physical therapy to regain the strength needed to attempt walking.

Cardiac xenotransplant chief Dr. Muhammad Mohiuddin said the team will analyze what happened with the heart as they continue studying pig organs.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Science and Educational Media Group and the Robert Wood Johnson Foundation.

LONDON (AP) — If your pet alligator escapes, don’t call for an ambulance — unless it has sunk its teeth into someone.That’s the message from the Welsh Ambulance Service in a plea to get people to stop phoning with non-emergencies.

With public health services stretched thin in the U.K., there is no shortage of anecdotes about people suffering from true health emergencies who wait hours for medical care — whether from paramedics or a hospital doctor. But the ambulance service said 15% of its 426,000 calls last year — 175 a day — were not urgent. Some weren’t even health-related and were far from being matters of life and death.There was a call about a chipped tooth (“it’s starting to throb”), a bloody toe (“I’ve cut my little nail on the toe and I’ve nipped across the top of it.”) and a person who stuck their finger in an electrical socket who appeared to be fine (“I’m worried that I could be electrocuted”).
