The study found that babies born to mothers with low B12 levels had higher leptin levels, which can lead to insulin resistance and an increased risk of type-2 diabetes.
A new review suggests that testing for inherited thrombophilia is often unnecessary and can be costly. Experts argue that hospital patients who have already had dangerous clots don't need the test to justify medication and preventive measures, and there's no evidence it helps prevent future clots.
Researchers have created computer models of blood flow through the heart's upper left chamber that may help predict stroke risk. The study found that a corkscrewlike motion helps move blood efficiently through the atrium, whereas an enlarged and diseased heart fails to form this motion, increasing the risk of developing a blood clot.
