First pig heart transplant patient dies after 2 months******

The first person to receive a heart transplant from a genetically modified pig has died two months after the medical milestone, the hospital that carried out the surgery said on Wednesday.
The procedure raised hopes that advances in cross-species organ donation could one day solve the chronic shortage of human organs available for donation, and the team behind the operation say they are "optimistic" about its future success.
David Bennett, 57, had received his transplant on January 7 and passed away on March 8, the University of Maryland Medical System said in a statement.
"There was no obvious cause identified at the time of his death," a hospital spokesman told AFP, adding that physicians were carrying out a review that would be published in a scientific journal.
Muhammad Mohiuddin, director of the university's cardiac xenotransplantation program, did, however, say in a video statement that Bennett was having "infectious episodes."
"We were having difficulty maintaining a balance between his immunosuppression and controlling his infection," he said.
Bennett's condition began deteriorating several days ago. After it became clear that he would not recover, he was given compassionate palliative care. He was able to communicate with his family during his final hours, a hospital statement said.
Following surgery, the transplanted heart had performed very well for several weeks without any signs of rejection, the hospital added.
Bennett was able to spend time with family, participated in physical therapy, watched the Super Bowl and spoke often about wanting to go home to see his dog Lucky.
Bennett came to the hospital in the eastern US state of Maryland in October 2021.
He was bed-ridden and placed on an emergency life support machine. He had been deemed ineligible for human transplant – a decision that is often taken when the recipient has very poor underlying health.
Mohiuddin said that the team had "gained invaluable insights" from the experience, adding: "We remain optimistic and plan on continuing our work in future clinical trials."
Reporting in US media also revealed Bennett was convicted of stabbing a man several times in 1988, leaving the victim paralyzed and wheelchair-bound before he died in 2005.
Medical ethicists hold that a person's past criminal history should have no bearing on their future treatment.
Preview: La Liga giants at stake in Copa del Rey second round******
MADRID, Dec. 13 (Xinhua) -- Several La Liga sides are in danger of being the victims of a Copa del Rey upset in the second round of Spain's knockout tournament this week.。
Although the first round matches, which saw La Liga teams play rivals from the fifth and sixth tiers, didn't produce any upsets (although Rayo Vallecano needed a penalty shootout against fifth-tier side Guijuelo), the second round sees sides from the top-flight play mainly rivals from the third and fourth tiers, and tends to produce at least two or three giant-killing acts.。
Tuesday sees Celta Vigo travel to face Andorra, who only just missed out on promotion to the second division last season. The side owned by Barcelona defender Gerard Pique and coached by former Barca assistant coach Eder Sarabia could spring a surprise if Celta leave key players such as Iago Aspas and Brais Mendez out of their starting 11.。
Wu Lei is likely to get a runout as Espanyol travel to central Spain to take on CD Palencia Cristo Atletico, who are currently in second place in their group in Spain's fourth tier.。
Struggling Alaves will have to be careful when they visit third tier side Linares Deportivo, and with Alaves more focused in climbing away from the danger zone at the bottom of La Liga, this is a game that could certainly be an upset, as is Levante's trip to play Alcoyano.。
Alcoyano scored a famous victory over Real Madrid last season and will fancy their chances of another top-flight scalp when they take on Levante, who have yet to win a league game this season and are currently rock bottom of the table.。
Other top flight sides who need to be very careful in the coming days are Elche, who visit an impressive Unionistas de Salamanca, while 2020 Copa del Rey winners Real Sociedad have to improve on their recent league form when they visit Zamora.。
Osasuna's trip to Deportivo la Coruna will rekindle memories of happier times for the home fans, and struggling Cadiz will have to be wary of their trip to Albacete, who were only relegated from the second division last season. Enditem。
