Popular blood pressure drugs could hold the key to weight loss

A study by Australian scientists has indicated that some of the most commonly used blood pressure medications could help people lose weight and body fat and reduce the likelihood of them developing diabetes.

New research suggests hypertonic, hyperviscous fluids may be better treatment for severe blood loss

Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but UC San Diego bioengineering researchers have reported improved resuscitation with a radically different approach. Building on earlier studies in humans that have shown benefits of intravenous fluids that are eight times saltier than normal saline, the researchers combined hypertonic saline with viscosity enhancers that thicken blood.

Aggregates of red and white blood cells may contribute to sickle cell disease

It's long been known that patients with sickle cell disease have malformed, "sickle-shaped" red blood cells - which are normally disc-shaped - that can cause sudden painful episodes when they block small blood vessels.

Fosamax use linked to atrial fibrillation in women

Women who have used Fosamax are nearly twice as likely to develop the most common kind of chronically irregular heartbeat (atrial fibrillation) than are those who have never used it, according to research from Group Health and the University of Washington published in the April 28 Archives of Internal Medicine.

Thyrotropin levels may be associated with coronary heart disease mortality in women

Women with increasing levels of thyrotropin within the normal range appear to have a higher risk of fatal coronary heart disease, according to a report in the April 28 issue of Archives of Internal Medicine.

Exercise helps lower heart disease risk in overweight women

The risk of heart disease in women associated with being overweight or obese is reduced but not eliminated by higher levels of physical activity, according to a report in the April 28 issue of Archives of Internal Medicine.

Abmormal behaviour of osteoglycin gene linked to heart and kidney problems

A gene that can cause the heart to become enlarged, greatly increasing the risk of heart attacks and heart failure, is identified today in a new study.

Alendronate may be associated with irregular heartbeat

Alendronate, a medication used to prevent fractures in women with osteoporosis, may be associated with an increased risk of atrial fibrillation, a type of abnormal heart rhythm, according to a report in the April 28 issue of Archives of Internal Medicine.

UCLA study identifies factors leading to hospital admission for heart failure

Nearly two out of three patients have one or more precipitating factors that may contribute to hospital admissions nationwide for heart failure, according to a new UCLA study. Pneumonia, irregular heart beats, and obstructed blood flow to the heart are the most frequent factors.

Minimally invasive heart bypass surgery using a DaVinci robot provides health and economic benefits

Minimally invasive heart bypass surgery using a DaVinci robot means a shorter hospital stay and faster recovery for patients, as well as fewer complications and a better chance that the new bypass vessels will stay open.

Discovery of important markers of high risk of type 2 diabetes

Doctors are aware of a range of risk factors, mostly related to the patients' family history, overweight, and lifestyle, that contribute to the risk of developing type 2 diabetes.

FDA approves Actonel (risedronate sodium) for postmenopausal osteoporosis

The U.S. Food and Drug Administration (FDA) approved a new once-a-month dose (150 mg) of Actonel (risedronate sodium) tablets for the treatment and prevention of postmenopausal osteoporosis. Actonel is approved to reduce the risk of fractures in postmenopausal women with osteoporosis.

Lower wealth, education and income associated with increased stroke up to age 65

Higher wealth is linked with a lower risk of stroke in Americans between the ages of 50 and 64, but does not predict strokes in those over age 65, researchers reported in Stroke: Journal of the American Heart Association.

Mitochondrial dysfunction and redox signaling in atrial tachyarrhythmia

Researchers at the University Hospital of Magdeburg (Germany) have discovered that atrial tachycardia is associated with mitochondrial dysfunction and oxidative stress followed by the activation of the NF-kB signalling pathway with induction of NF-kB target gene expression in atrial tissue.

New 3-D ultrasound provides clear images of the major arteries within the brain

Using 3-D ultrasound technology they designed, Duke University bioengineers can compensate for the thickness and unevenness of the skull to see in real-time the arteries within the brain that most often clog up and cause strokes.

Beta arrestins found to generate new proteins

Duke University Medical Center researchers have recently discovered that a crucial communications pathway in cells not only stops cells from making proteins, it also makes them go. The team was able to define the way in which proteins called beta arrestins (for their role in stopping signals) also turn on pathways that ultimately lead to the production of new proteins in virtually all tissues in the body.

Metabolic genes tied to inflammatory predictor of heart disease and stroke risk

Two new studies provide evidence that differences in people's blood levels of C reactive protein (CRP) stem in part from natural variation in known metabolic genes. The researchers report their findings in the May American Journal of Human Genetics, a publication of Cell Press.
