Physicians offer new solution for blood transfusions


The successful transfusion of a cell-free blood product on a 14-year-old Jehovah’s Witness may offer a solution for patients opposed to blood transfusions due to religious or personal beliefs.

"This was the first successful use of a human cell-free hemoglobin solution in a pediatric patient to manage life-threatening anemia due to an autoimmune disease," says Dr. Brian Kavanagh, professor of medicine at the University of Toronto and staff physician in critical care medicine at The Hospital for Sick Children. The patient suffered from immune thrombocytopenia, a condition that attacks platelets in the body. Platelets are present in blood and help blood clot; if platelet counts are very low, minor injuries or trauma can become very serious if the patient continues to bleed.

Kavanagh and colleagues Drs. Johann Hitzler and Natalie Anton treated the patient last year after she entered the hospital’s emergency room for a nosebleed that did not stop. Instead of a blood transfusion, they used a biochemically manufactured solution that contains hemoglobin but does not contain red blood cells. The solution has been used in adults but never for a child in this kind of situation, Kavanagh says.

While more study needs to be done with pediatric patients, Kavanagh says this cell-free hemoglobin is a viable alternative for Jehovah’s Witnesses. "Most current blood replacement options are fluids, plasma and other types of liquids that provide volume for blood but don’t provide the oxygen-carrying capacity. This solution provides oxygen-carrying capacity in exactly the same way that blood cells in hemoglobin do. That’s the crux of the matter. Still, only careful study will fully determine the balance of benefits and risk."

Kavanagh and colleagues reported this case in a fall issue of the British Journal of Haematology.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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...
