Elevated Glucose Associated With Undetected Heart Damage
A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests that hyperglycemia (high blood sugar) injures the heart, even in patients without a history of heart disease or diabetes. Researchers found that elevated levels of glycated hemoglobin (HbA1c), a marker for chronic hyperglycemia and diabetes, were associated with minute levels of the protein troponin T (cTnT), a blood marker for heart damage. The high-sensitivity test they used detected levels of cTnT tenfold lower than those found in patients diagnosed with a heart attack.
Link Between Heart Failure And Thinner Bones And Fractures
Heart failure is associated with a 30 percent increase in major fractures and also identifies a high-risk population that may benefit from increased screening and treatment for osteoporosis, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Osteoporosis and heart failure are common, chronic and costly conditions that share common etiologic factors like older age, post-menopausal status and diabetes. Previous studies have suggested that heart failure may predispose a patient to fractures not only because it increases incidence of falling, but because both heart failure itself and its medical treatments can lead to loss of bone mass.
Chemists Unlock Potential Target For Drug Development
A receptor found on blood platelets whose importance as a potential pharmaceutical target has long been questioned may in fact be fruitful in drug testing, according to new research from Michigan State University chemists. A team led by Dana Spence of MSU's Department of Chemistry has revealed a way to isolate and test the receptor known as P2X1. By creating a new, simple method to study it after blood is drawn, the team has unlocked a potential new drug target for many diseases that impact red blood cells, such as diabetes, hypertension and cystic fibrosis.
