Woman Who Received Pig Kidney Along with Implanted Heart Device Dies After 47 Days

-

Lisa Pisano, a New Jersey woman who underwent a groundbreaking medical procedure involving a pig kidney transplant and an implanted heart pump, has sadly passed away after 47 days of complications. 

Summarized Insights:

• Lisa Pisano undergoes pig kidney transplant

• Complications arise from heart medications

• Contributions to xenotransplantation research

• Challenges and lessons for future trials

Her case, aimed at advancing xenotransplantation research, highlights both the potential and challenges of using animal organs to alleviate the critical shortage of transplantable human organs.

Lisa Pisano was near death from kidney and heart failure when surgeons at NYU Langone Health undertook the complex surgeries in April. 

Initially, her condition seemed to improve following the dual procedures, which involved not only a pig kidney transplant but also the insertion of an implanted device to assist her heart function.

However, approximately 47 days later, complications arose when her heart medications began to damage the pig kidney. 

As a result, doctors had to remove the kidney and place Pisano back on dialysis. 

Despite efforts to stabilize her condition with dialysis and the implanted heart pump, Pisano's health continued to deteriorate, eventually leading to her entering hospice care, where she passed away.

Dr. Robert Montgomery, the transplant surgeon at NYU Langone Health, praised Pisano for her bravery in participating in the experimental procedure. 

He emphasized that Pisano's willingness to undergo such pioneering treatment contributed significantly to advancing medical knowledge in xenotransplantation.

"Lisa helped bring us closer to realizing a future where someone does not have to die for another person to live," Montgomery stated in a tribute to Pisano's courage and contribution to medical science.

Lisa Pisano was the second person ever to receive a kidney from a gene-edited pig as part of ongoing efforts to develop organs that are less likely to be rejected by recipients' immune systems. 

The first recipient, Richard "Rick" Slayman, received a similar transplant but passed away nearly two months later due to preexisting heart disease unrelated to the transplant.

Xenotransplantation remains a promising avenue for addressing the critical shortage of organs for transplantation. 

With over 100,000 people currently on the U.S. transplant waiting list, most of whom require kidneys, the need for viable alternatives is urgent. 

Biotech companies are actively involved in genetically modifying pigs to make their organs more compatible with human recipients, aiming to overcome immune rejection issues.

While the outcomes of Lisa Pisano and Richard Slayman underscore the challenges and risks associated with xenotransplantation, they also provide valuable insights for future research and clinical trials. 

The lessons learned from these pioneering cases, coupled with ongoing research advancements, offer hope for improving outcomes and expanding the potential pool of transplantable organs.

As medical science continues to push boundaries in organ transplantation, the contributions of individuals like Lisa Pisano serve as poignant reminders of the courage and determination required to advance medical frontiers in the quest to save lives.

60-Year-Old Truck Driver Sues San-Ikukai Hospital After Learning He Was Switched at Birth from Wealthy Family

-

When a humble lorry driver from Tokyo discovered that he had been switched at birth with a child from a wealthy family, his entire understanding of his life crumbled overnight. For sixty years, he had labored under the weight of poverty, unaware that fate — and a hospital’s mistake — had robbed him of the life he was meant to live.  What began as an ordinary working-class existence became the centerpiece of one of Japan’s most shocking cases of medical negligence, sparking debate over accountability, class disparity, and the meaning of identity. The man’s story, which surfaced publicly in 2013, remains a haunting reminder of how one careless act can alter generations. A Life Stolen by a Hospital’s Mistake Born in 1953 at San-Ikukai Hospital in Tokyo’s Sumida district, the unnamed man was one of two baby boys delivered on the same day. In the confusion of a busy post-war maternity ward, nurses mistakenly sent each infant home with the wrong family. One baby went to an affluent hou...

Staff pushed her off the platform without attaching the essential safety rope, leading to her death at the scene from multiple traumatic injuries. Maria Eduarda, a recent graduate in Physical Education and Sports Management, was known as a fitness enthusiast and gym professional from Jandira, São Paulo. She embraced an active lifestyle, often sharing her passion for outdoor activities and sports on social media. Friends and family described her as vibrant and adventurous, someone who approached life with enthusiasm. Just moments before the jump, she posted photos and stories on Instagram showing the bridge, her wristbands for the e...

Not Climate Change but Humans Are Responsible for Extinction of Giant Mammals in the Last 50,000 Years

-
Image
The Earth’s ancient landscapes were once dominated by an incredible array of megafauna—giant mammals, birds, and reptiles that roamed freely across continents.  Fifty thousand years ago, there were 57 species of megaherbivores.  Today, only 11 remain, and these survivors have also seen significant declines in their populations.  While it has long been believed that climate change and environmental shifts were the primary drivers of these extinctions, new evidence points to a different culprit: human intervention. The extinction crisis, which saw at least 161 species of large mammals driven to extinction, is now increasingly attributed to human activities.  Researchers from the Danish National Research Foundation's Center for Ecological Dynamics in a Novel Biosphere (ECONOVO) at Aarhus University have presented compelling evidence that humans played a central role in these extinctions through extensive hunting practices. During the late Pleistocene epoch, which spanne...

In a poignant symbol of political change, a piano and a red sofa were among the items removed from Downing Street following Rishi Sunak’s defeat in the recent General Election.  As Labour's Sir Keir Starmer and Chancellor Rachel Reeves prepare to move into the historic residence, the process of transferring the keys to the new occupants is well underway. The General Election marked a significant shift in British politics, with Labour emerging victorious and ending Rishi Sunak’s tenure as Prime Minister.  As the political landscape of Downing Street changes, so too does the physical setup of the residences at No 10 and No 11, which have been central to British political life for decades.  The transition involves not just a change of leadership but also a shift in the very spaces that have been the backdrop to numerous historic events. On Sunday, a bright yellow lorry from the moving company Bishop’s Move was seen parked at the rear of Downing Street.  The moving proce...

  In a crime that has left law enforcement officials and local residents scratching their heads, a Georgia man has been arrested for allegedly stealing an entire metal roof from a vacant home in Reynolds. The audacious theft, which occurred in Taylor County, highlights the lengths some individuals will go to for scrap metal or quick profit, turning a quiet rural property into the scene of one of the most unusual burglaries in recent memory.

Scientists in Search of Female Companion for the World's Loneliest Plant

-
Image
"Surely this is the most solitary organism in the world," wrote palaeontologist Richard Fortey in his book about the evolution of life, referring to Encephalartos woodii (E. woodii).  This remarkable plant, a native of South Africa, is a member of the ancient cycad family, known for their thick trunks and large, stiff leaves that form majestic crowns.  These resilient survivors have outlasted dinosaurs and multiple mass extinctions, yet today they stand among the most threatened species on the planet. The story of E. woodii began in 1895 when botanist John Medley Wood discovered the only known wild specimen during a botanical expedition in the Ngoye Forest in South Africa.  Despite thorough searches, no other specimens were found.  Over the next few decades, botanists cultivated stems and offshoots from this lone plant in gardens.  To protect it from potential destruction, the final stem was removed from the wild in 1916 and placed in a protective enclosure in P...
