Umbilical cord blood not suitable for assessing allergy risk
For years, hospitals and researchers have been testing blood samples from the umbilical cords of newborn babies to assess the risk of allergy. Now a study at the University of Copenhagen has revealed that the biomarker in the blood that indicates the risk factor for allergy often comes from the mother rather than her baby. (2010-10-05)

A new study published in Transfusion reveals that there is a significant distrust in the health care system among the African-American community, and African-Americans who distrust hospitals are less likely to donate blood. (2010-09-10)

Education more important than knowledge in stopping spread of HIV in Africa
Simply teaching people the facts about how to protect themselves from HIV may not be enough to prevent the spread of AIDS in Africa, a new study suggests. Researchers found that villagers in Ghana who had higher levels of cognitive and decision-making abilities -- not just the most knowledge -- were the ones who were most likely to take steps to protect themselves from HIV infection. (2010-09-08)

Hospital study suggests that early transfusion increases acute upper GI re-bleeding risk
Doctors have called for an urgent review of transfusion policies after a UK-wide study of 221 hospitals found that patients admitted with acute upper gastrointestinal bleeding are more than twice as likely to suffer further bleeding if they receive a red blood cell transfusion within 12 hours. The study also found that death rates were more than a quarter higher in patients who had received transfusions within that timescale. (2010-07-07)

Mothers' high blood sugar in pregnancy is linked to children's reduced insulin sensitivity
Children of mothers whose blood glucose (sugar) was high during pregnancy are more likely to have low insulin sensitivity -- a risk factor for type 2 diabetes -- even after taking into consideration the children's body weight, a new study shows. The results will be presented Tuesday at the Endocrine Society's 92nd Annual Meeting in San Diego. (2010-06-22)

Tiny blood vessels in brain spit to survive
Scientists at Northwestern University have discovered capillaries have a unique method of expelling debris, such as blood clots, cholesterol or calcium plaque, that blocks the flow of essential nutrients to brain cells. The capillaries spit out the blockage by growing a membrane that envelopes the obstruction and then shoves it out of the blood vessel. Scientists also found this critical process is up to 50 percent slower in an aging brain and likely results in the death of more capillaries. (2010-05-26)

Banning all gay men from donating blood is unscientific and wrong, say AIDS research pioneers
Since 1983, blood agencies in Canada, the United States and many other industrialized nations have disallowed all blood donations from men who have sex with men. While a total ban was justified scientifically and ethically in 1983, in 2010 it no longer makes sense, say pioneering AIDS researchers Dr. Mark Wainberg and Dr. Norbert Gilmore in an article to be published May 25 in the Canadian Medical Association Journal. (2010-05-25)

Do we clamp the umbilical cord too soon?
The timing of umbilical cord clamping at birth remains controversial. The cord has been clamped early to facilitate resuscitation and stabilization of infants.

Media availability: New study suggests sickle cell disease may affect brain function
Adults who have mild sickle cell disease scored lower on brain function tests when compared to healthy participants, suggesting the blood disease may impact the brain more than previously realized, according to new research published in the May 12 issue of the Journal of the American Medical Association.

High cholesterol levels affect mobilization of cells from the bone marrow
Researchers in Portugal show that high levels of cholesterol can affect the microenvironment of the bone marrow, so that more cells move from the bone marrow to peripheral, circulating blood. These findings, by Sergio Dias and his team, an external group of the Instituto Gulbenkian de Ciencia, have implications for transplantation and further understanding bone marrow malignancies, are to appear in the next issue of the journal Blood. (2010-05-10)

New treatment method in sight in cardiac surgery
A joint clinical trial conducted by the University Hospital and the University of Gothenburg, Sweden, found that an element in human blood, fibrinogen, is likely more vital to the blood's clotting ability in connection with heart surgery than previously considered. If the patients also receive a dose of fibrinogen prior to the procedure, this reduces the risk of hemorrhage during and after surgery. These results may open the door to new strategies in reducing bleeding complications in cardiac surgery. (2010-05-09)
