Temple researchers shed new light on double-lung transplants

Temple researchers find equivalent outcomes for double-lung transplants when blood type between donor and recipient is identical or compatible

In the largest retrospective study to date using data from the United Network for Organ Sharing (UNOS) database for adult double-lung transplants, Temple University School of Medicine researchers have shown that there is no statistically significant difference between rejection and mortality rates among double-lung transplant recipients when their transplanted organs came from donors whose blood-type was identical or compatible to their own.

"The study confirms what most of us in the transplant surgical community have recognized for some time based on our clinical experience," said senior author Yoshiya Toyoda, MD, PhD, Vice Chief of Cardiothoracic Surgery and Surgical Director Heart and Lung Transplantation at Temple University Hospital (TUH), in Philadelphia. Dr. Toyoda, who has performed more than 300 double-lung transplantations, also serves as Surgical Director of Mechanical Circulatory Support at TUH.

Toyoda and his colleagues found that the use of lungs from donors whose blood type was compatible, but not identical, to the recipient's was not associated with short- or long-term mortality and resulted in equivalent post-transplant lung function. "Using lungs from carefully selected blood-type compatible donors can result in excellent outcomes for double-lung transplant recipients," said Dr. Toyoda.

Dr. Toyoda noted that, given the scarcity of available organs, the ability of surgeons to expand the pool of potential donated organs to include lungs from blood-type compatible donors benefits patients awaiting organs.

Other authors on the Temple study were Sharven Taghavi, MD, Senthil Jayarajan, and T. Sloane Guy, MD.

About Temple Health

Temple Health refers to the health, education and research activities carried out by the affiliates of Temple University Health System and by Temple University School of Medicine. Temple University Health System (TUHS) is a $1.4 billion academic health system dedicated to providing access to quality patient care and supporting excellence in medical education and research. The Health System consists of Temple University Hospital (TUH), ranked among the "Best Hospitals" in the region by U.S. News & World Report; TUH-Episcopal Campus; TUH-Northeastern Campus; Fox Chase Cancer Center, an NCI-designated comprehensive cancer center; Jeanes Hospital, a community-based hospital offering medical, surgical and emergency services; Temple Transport Team, a ground and air-ambulance company; and Temple Physicians, Inc., a network of community-based specialty and primary-care physician practices. TUHS is affiliated with Temple University School of Medicine.

Temple University School of Medicine (TUSM), established in 1901, is one of the nation's leading medical schools. Each year, the School of Medicine educates approximately 840 medical students and 140 graduate students. Based on its level of funding from the National Institutes of Health, Temple University School of Medicine is the second-highest ranked medical school in Philadelphia and the third-highest in the Commonwealth of Pennsylvania. According to U.S. News & World Report, TUSM is among the top 10 most applied-to medical schools in the nation.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
