New research has shown the presence of a disease affecting small blood vessels, known as microangiopathy, in the bone marrow of diabetic patients. While it is well known that microangiopathy is the cause of renal damage, blindness and heart attacks in patients with diabetes, this is the first time that a reduction of the smallest blood vessels has been shown in bone marrow, the tissue contained inside the bones and the main source of stem cells. http://medicalxpress.com/news/2013-01-diabetes-distresses-bone-marrow-stem.html Diabetes Thu, 31 Jan 2013 16:00:01 EST news278869521 Scientists at the Stanford University School of Medicine have identified a set of proteins circulating in blood whose levels accurately flag the presence of lymphedema. The findings, to be reported Dec. 18 in PLoS ONE, spur optimism that this common but relatively neglected condition, which affects an estimated 10 million people in the United States, finally will be amenable to detection (and, eventually, treatment) with 21st-century techniques. http://medicalxpress.com/news/2012-12-blood-accurately-lymphedema.html Inflammatory disorders Tue, 18 Dec 2012 17:00:05 EST news275072203 Although there is a widespread belief among physicians that the exercise treadmill test (ETT) is not reliable in evaluating the heart health of women, UC Davis researchers have found that the test can accurately predict coronary artery disease in women over the age of 65. They also found that two specific electrocardiogram (EKG) indicators of heart stress during an ETT further enhanced its predictive power. http://medicalxpress.com/news/2012-12-treadmill-heart-disease-women.html Cardiology Thu, 06 Dec 2012 15:07:43 EST news274028840 Digoxin, a drug widely used to treat heart disease, increases the possibility of death when used by patients with a common heart rhythm problem − atrial fibrillation (AF), according to new study findings by University of Kentucky researchers.
