Ventricular factors linked to early and late post-cardiac surgery mortality

Increased left ventricular mass index predicts perioperative mortality in patients undergoing cardiac surgery, while a decreased fractional area of contraction in the left ventricle is linked to 1-year mortality, US scientists have found.

Physical activity effective in reducing sclerostin in premenopausal women

A study to be published in the Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM) suggests that physical activity for premenopausal women is very effective in reducing sclerostin-a known inhibitor of bone formation. In addition, physical training enhances IGF-1levels, which have a very positive effect on bone formation.

Tranexamic acid reduces bleeding in off-pump coronary bypass surgery

Patients undergoing off-pump coronary artery bypass grafting who are given a tranexamic acid infusion show a modest reduction in postoperative bleeding and blood transfusion relative to their placebo-treated peers, a clinical trial shows.

Risk model predicts illness after ambulatory surgery

A marked proportion of patients undergoing ambulatory surgery suffer postdischarge nausea and vomiting, say US scientists who have developed a simplified risk score to identify patients who may benefit from long-acting prophylactic therapy.

Researchers uncover 9 new genes associated with bone health

Researchers have uncovered 9 new genes associated with bone health. This collaborative study found clues to the cause of bone disorders such as osteoporosis, osteogenesis imperfecta, and high bone density syndromes by investigating the bone mineral content, strength and flexibility.

Rodents may hold the key to long and active lifespan

Compared to the average three year life span of a common rat, the 10 to 30 year life of the naked mole rat, a subterranean rodent native to East Africa, is impressive. And compared to the human body, the body of this rodent shows little decline due to aging, maintaining high activity, bone health, reproductive capacity, and cognitive ability throughout its lifetime. Now a collaborative of researchers in Israel and the United States is working to uncover the secret to the small mammal's long - and active - lifespan.
