Blood transfusions associated with infection

A study of almost 25,000 coronary artery bypass graft (CABG) patients has shown that receiving blood from another person is associated with a two-fold increase in post-operative infection rates. The research, published in the open access journal BMC Medicine, also found considerable hospital variation in transfusion practices.

Short-term complications after bariatric surgery for extreme obesity low

Short-term complications and death rates were low following bariatric surgery to limit the amount of food that can enter the stomach, decrease absorption of food or both, according to the Longitudinal Assessment of Bariatric Surgery (LABS-1). The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health. Results are reported in the July 30 issue of the New England Journal of Medicine.

Protein level may predict severe osteoarthritis

Osteoarthritis (OA), the most common joint disorder throughout the world and a leading cause of disability, is characterized by pain, impaired joint mobility, reduction of muscular strength and loss of joint function. Unlike most other common diseases, little is known about its origins, and factors predicting a severe disease course have not been identified.

Plenty of dairy foods in childhood may mean a longer life

Milk is an excellent source of calcium and the children who ate plenty of dairy foods such as milk and cheese appeared to be protected against stroke and other causes of death, even though dairy products often contain fats and cholesterol which fur up the arteries and high consumption of dairy products did not raise the heart disease risk.

Hypertension may lead to ‘silent’ strokes

"Silent" strokes, which are strokes that don't result in any noticeable symptoms but cause brain damage, are common in people over 60, and especially in those with high blood pressure, according to a study published in the July 28, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Enjoyable leisure activities tied to psychological and physical well-being

Taking time for leisure activities apart from the demands of work and other responsibilities helps people function better physically and mentally. In fact, the more time spent doing different types of enjoyable activities, the better a person's health tends to be, according to a new study.

World's first genetically-modified strain of malaria parasite

Walter and Eliza Hall Institute scientists have created a weakened strain of the malaria parasite that will be used as a live vaccine against the disease. The vaccine, developed in collaboration with researchers from the US, Japan and Canada, will be trialled in humans from early next year.

Gene expression patterns in cancer could aid early screening and prevention

Distinctive patterns of genes turned off - or left on - in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say.

Deferoxamine could help diabetics heal wounds

A drug used to remove iron from the body could help doctors fight one of diabetes' cruelest complications: poor wound healing, which can lead to amputation of patients' toes, feet and even legs.

Current diagnostic tests for ovarian cancer woefully ineffective

A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years.

Cost effectiveness study looks at potential value of new genetic test for guiding chemotherapy treatment

For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death.
