Petra Joller: For insdiermedicinein60 I'm Petra Joller from Cleveland. The age of blood used in transfusions may affect the risk of death. Nearly 3,000 patients having cardiac surgery who received transfusions with blood that was stored for less than 2 weeks were compared to another 3,000 patients who received blood that was stored for longer periods of time. Researchers found a nearly 50% reduction of in-hospital death following surgery in those who received blood that was stored for less than 2 weeks. From New York, a new study suggests that while a happy marriage is good for your blood pressure, an unhappy one can be worse for you than being single. The study examined over 200 married people, and nearly 100 single adults and found that those reporting higher levels of marital satisfaction had lower average blood pressure, but spouses reporting low martial satisfaction had blood pressure readings that were five points higher than those that were unmarried. Finally from Berkeley, what males eat may raise the risk of chromosomal abnormalities in the sperm and raise the risk of having a child with a developmental delay. While much attention has focused on maternal nutrition during pregnancy, little has been done to understand the effects of nutrition on sperm. In this study, men who ate the highest levels of folate had a 20% lower rate of having aneuploidic sperm, a situation where an extra chromosome is contributed to an egg.
