when many people were homebound. And it continues to grow, Phillips says.

“This is uncharted territory,” said Mass General’s Dr. Tatsuo Kawai, who led both Andrews’ surgery and the world’s first pig kidney transplant last year. But with lessons from animal research and the prior human attempts, he said, “I’m very optimistic. And hopefully we can get to survival, kidney survival, for over two years.”so their organs are more humanlike to address the transplant shortage. More than 100,000 people are on the U.S. transplant list, most who need a kidney, and thousands die waiting.

Andrews’ kidneys abruptly failed about two years ago, and the Concord, New Hampshire, grandfather struggled with fatigue and complications from dialysis. He’s on the transplant list but doctors warned it was a long shot. It can take seven years or more for people with Andrews’ blood type to find a matching kidney. Meanwhile, people slowly get sicker on dialysis — five-year survival is about 50% — and Andrews already had had a heart attack.“I have seen my mortality and I was ready to fight,” Andrews said. So he asked Mass General if he could get a pig kidney instead. “I told them. ‘Anything, I’ll do anything. You give me a list of things you want me to do and I’ll do it.’”Mass General transplant nephrologist Dr. Leonardo Riella said Andrews was weak and struggling with diabetes, including a slow-healing diabetic foot ulcer that hindered walking. He’d have to get more fit to be a candidate.

Andrews started physical therapy and returned six months later about 30 pounds lighter and “running down the hallway almost,” Riella recalled. “He was just, you know, a different person,” so they started checking if he’d qualify for the pilot study.One big question was cardiac fitness: Mass General’s

had underlying heart disease that killed him. But Riella said intense exams showed Andrews’ “heart was in the best shape possible.”

Still, Andrews was a little nervous and sought advice from the only other person who knew what a pig kidney transplant was like — the NYU patient, Towana Looney.of thousands of international students before reversing itself and then

He also doesn’t feel safe leaving the U.S. even when appointments resume.

“I don’t think I have enough trust in the system at this point,” said Plyaka, who came to the U.S. from Ukraine as an exchange student in high school and stayed for college. “I understand it probably is done for security measures, but I would probably just finish my education for the next two or three years and then come back to Ukraine.”AP Washington correspondent Sagar Meghani reports on more Trump administration steps targeting international students.
