New Lung Preservation System May Boost Number of Transplants: FDA
A newly-approved device that preserves donated lungs for transplantation may boost the number of lung transplants in the United States, according to the Food and Drug Administration.
The XVIVO Perfusion System (XPS) with STEEN Solution preserves donated lungs that do not initially meet standard criteria for lung transplantation, but which may be transplantable if there is more time to observe and evaluate their function to determine whether they are viable for transplantation, the FDA explained.
The agency announced Tuesday that it had its approved the system.
"This innovative device addresses a critical public health need," Christy Foreman, director of the Office of Device Evaluation at the FDA's Center for Devices and Radiological Health, said in an agency news release.
"With this approval, there may be more lungs available for transplant, which could allow more people with end stage lung disease who have exhausted all other treatment options to be able to receive a lung transplant," Foreman explained.
Only about one in five donated lungs meets the standard criteria for a donor lung and is transplanted into a patient. There were 1,754 lung transplants performed in the U.S. in 2012, but more than 1,616 were still on the waiting list at the end of the year, the FDA said.
Tick Bites Linked to Red Meat Allergy
Bites from a certain type of tick can make people allergic to red meat, according to experts.
As Lone Star ticks have spread from the Southwest to the East Coast of the United States, the number of people suffering an allergic reaction after eating red meat has increased, CBS News reported.
However, many doctors and patients are unaware of this growing problem.
"Why would someone think they're allergic to meat when they've been eating it their whole life?" Dr. Erin McGintee told CBS News. She's an allergist who has reportedly seen 200 cases of this type of red meat allergy among people on New York's Long Island.
Lone Star ticks carry a sugar called alpha-gal, which is also found in red meat, but not in people. Normally, alpha-gal in meat poses no problems for people. But when a Lone Star tick bites a person, it transfers alpha-gal into the bloodstream.
As a result, the person's body produces antibodies to fight the sugar. The next time that person eats red meat, their immune system responds to the alpha-gal in the meat and they suffer an allergic reaction that can include itching, burning, hives and even throat swelling, CBS News reported.
In cases of mild allergic reactions, the symptoms can be treated with antihistamines, but severe allergic reactions (anaphylactic shock) require epinephrine. Some people with the red meat allergy carry EpiPens that deliver a shot of epinephrine.
Most allergic reactions to foods occur almost immediately, but red meat allergic reactions can occur up to eight hours after a person eats meat, CBS News reported.
It's not yet known if red meat allergy is permanent. While some people show indications of recovery, others do not.
Robin Williams, Comedian, Film Star, Dead at 63
Robin Williams, a star comedian who could also move audiences deeply with the convincing power of his dramatic acting, died Monday of an apparent suicide.
He was 63.
The Academy Award-winning actor, who was found dead shortly after noon in his home near San Francisco, had been battling severe depression, according to his publicist. In July, Williams had returned to a 12-step treatment program that he said he needed after 18 months of nonstop work, the Associated Press reported. After suffering a relapse from drinking in 2006, he had also sought treatment, the wire service said.
"This morning, I lost my husband and my best friend, while the world lost one of its most beloved artists and beautiful human beings. I am utterly heartbroken," Williams' wife, Susan Schneider, said in a statement. "On behalf of Robin's family, we are asking for privacy during our time of profound grief. As he is remembered, it is our hope the focus will not be on Robin's death, but on the countless moments of joy and laughter he gave to millions."
Although his manic, brilliant brand of comedy was his signature talent, Williams tackled many dramatic roles, including ones in "Awakenings," "Dead Poets Society" and "What Dreams May Come." He won an Academy Award for his role as a therapist in the film "Good Will Hunting," and captured three Golden Globes, for "Good Morning, Vietnam," "Mrs. Doubtfire" and "The Fisher King."
