Lee Rannals for redOrbit.com - Your Universe Online Findings presented at the American Heart Association's Basic Cardiovascular Sciences 2012 Scientific Sessions show that adult stem cells extracted during liposuction can be used to grow small-diameter blood vessels that could be used in heart bypass surgery. Matthias Nollert, the lead author of the study, said these liposuction-derived vessels could help solve major problems associated with grafting blood vessels from other places in...

By: Katie Williams, Ivanhoe Health Correspondent (Ivanhoe Newswire) — Millions of patients affected by cardiovascular disease need small-diameter blood vessel grafts to help route their blood around blocked arteries. Now, researchers have created a new way to grow healthy, new small-diameter blood vessels from adult stem cells extracted during liposuction. These blood vessels are grown in a lab and could solve large problems associated with grafting blood vessels elsewhere in the...

Jehovah's Witness patients who undergo cardiac surgery do not appear to be at increased risk for surgical complications or death when compared to patients who undergo cardiac surgery and receive blood transfusions, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication. Jehovah's Witness patients (Witnesses) hold beliefs that disallow blood product transfusion and encourage the use of a number of blood conservation practices, according to...

Oxygen microparticles could deliver oxygen when breathing is impaired Patients unable to breathe because of acute lung failure or an obstructed airway need another way to get oxygen to their blood–and fast–to avoid cardiac arrest and brain injury. A team led by researchers at Boston Children's Hospital has designed tiny, gas-filled microparticles that can be injected directly into the bloodstream to quickly oxygenate the blood. The microparticles consist of a single layer of...

Blood Transfusions May Do More Harm Than Good

Johns Hopkins study shows wide variation in transfusion use in operating rooms Citing the lack of clear guidelines for ordering blood transfusions during surgery, Johns Hopkins researchers say a new study confirms there is still wide variation in the use of transfusions and frequent use of transfused blood in patients who don't need it. The resulting overuse of blood is problematic, the researchers say, because blood is a scarce and expensive resource and because recent studies have...

A lot of people were skeptical when two young California-based researchers set out more than a decade ago to create a completely human-derived alternative to the synthetic blood vessels commonly used in dialysis patients. Since then, they've done that and more. "There were a lot of doubts in the field that you could make a blood vessel, which is something that needs to resist pressure constantly, 24-7, without any synthetic materials in it," explains Nicolas L'Heureux, a co-founder and the...

Less Blood Required Post-surgery

Results would reduce number of transfusions, saving millions of dollars annually Patients need less blood after surgery than is widely thought. A new study comparing two plans for giving blood transfusions following surgery showed no ill effects from postponing transfusion until patients develop signs of anemia or their hemoglobin concentration falls below 8 g/dL. Results of the National Heart and Lung and Blood Institute—funded study were published Dec. 15 in the New England...

Vampires on the True Blood television series are already enjoying the advantages of synthetic blood. While this may seem to be only the imagination on the big screen, the true benefits of blood manufactured from embryonic stem cells may be less than a decade away. It is unclear however whether society can develop an acceptance of cultured blood - or an appetite for synthetic meat produced by related technology.  For this reason it is vital the public has every opportunity to get...
