Researchers link blood sugar to normal cognitive ageing
— 30 Dec 2008 | HealthMaintaining blood sugar levels, even in the absence of disease, may be an important strategy for preserving cognitive health, suggests a study published by researchers at Columbia University Medical Centre (CUMC). The study appeared in the December issue of Annals of Neurology…
Researchers identify common gene variant linked to high blood pressure
— 30 Dec 2008 | HealthResearchers at the University of Maryland School of Medicine have identified a common gene variant that appears to influence people's risk of developing high blood pressure, according to the results of a study being published online 29 December in the Proceedings of the National Academy of Sciences (PNAS)…
Can't chalk it up to 'baby fat'
— 30 Dec 2008 | HealthDespite recent widespread media attention given to studies that have indicated one-third of American children have a weight problem, a new study shows just one-third of children who are overweight or obese actually receive that diagnosis by a paediatrician. The study, led by researchers at The MetroHealth System and Case Western Reserve University School of Medicine in Cleveland, also stresses that this failure to diagnose appears to mostly impact children who may most greatly benefit from early intervention…
Study investigates the cost effectiveness of spinal surgery
— 30 Dec 2008 | HealthBack pain affects more than 80 percent of people and costs more than $100 billion annually in the U.S. But is the surgery cost effective? A study by researchers at Rush University Medical Centre suggests that for patients with spinal stenosis, a laminectomy, or surgical removal of some soft bone and tissue, is a reasonable value. However, for patients with spinal stenosis with associated slipped vertebrae, the benefits of spinal fusion surgery may not be enough to offset costs…
Fungal pill could provide asthma relief for 150 000 UK sufferers
— 30 Dec 2008 | HealthUp to 150,000 people suffering from severe asthma in the UK could benefit from taking antifungal medication already available from pharmacists, new research has found…
A new screening test for chronic abdominal pain
— 30 Dec 2008 | HealthEvaluation of chronic abdominal pain of luminal aetiology is a challenging problem for the primary care physicians and gastroenterologists. The exact localisation of lesion to either small or large bowel remains an elusive identity in many subjects…
May hepatic granulomas be part of the histological spectrum of chronic hepatitis C?
— 30 Dec 2008 | HealthWhile older large series of patients with hepatic granulomas have found sarcoidosis and tuberculosis to be the most common causes of hepatic granulomas, recent works have noted some patients with chronic hepatic C and hepatic granulomas and no other obvious associations. Today, patients that undergo liver biopsy often have chronic hepatitis C that is being staged prior to possible anti viral therapy. The age of HIV and immunosuppression for organ transplants has also made opportunistic infections associated with hepatic granulomas more likely…
Researchers find what drives one of nature's powerful, nanoscale motors
— 30 Dec 2008 | BiologyPeering at structures only atoms across, researchers have identified the clockwork that drives a powerful virus nanomotor. Because of the motor's strength - to scale, twice that of an automobile - the new findings could inspire engineers designing sophisticated nanomachines. In addition, because a number of virus types may possess a similar motor, including the virus that causes herpes, the results may also assist pharmaceutical companies developing methods to sabotage virus machinery…
Moderate drinking can reduce risks of Alzheimer's dementia and cognitive decline
— 30 Dec 2008 | HealthModerate drinkers often have lower risks of Alzheimer's disease and other cognitive loss, according to researchers who reviewed 44 studies. In more than half of the studies, published since the 1990s, moderate drinkers of wine, beer and liquor had lower dementia risks than nondrinkers. In only a few studies were there increased risks…
Scientists isolate genes that made 1918 flu lethal
— 30 Dec 2008 | HealthBy mixing and matching a contemporary flu virus with the 'Spanish flu' - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus…
