Blood-thinner linked to osteoporotic fractures
The long-term use of warfarin, a drug commonly prescribed to reduce the risk of blood clots, appears to increase the risk of fractures associated with osteoporosis, a bone-thinning condition that usually increased with age, according to a report.
As the study authors note, warfarin prevents coagulation by blocking vitamin K, which is needed to activate certain clotting factors. Because vitamin K is also used to activate proteins involved in bone formation, drugs like warfarin may increase the risk of fractures, the researchers report in the Archives of Internal Medicine.
Researchers use new approach to ‘break the code’ for liver cancer test
Scientists at Birmingham University are using cutting edge technologies to move closer to a blood test that will improve early diagnosis of liver cancer in high risk groups, according to research published in the British Journal of Cancer.
Cancer which first arises in the liver, or hepatocellular carcinoma, is the sixth most common cancer in the world, being especially widespread in East Asia. Treatment works better the earlier it is administered, so finding a way to pick up small tumours in the liver is crucial. High-risk groups, such as people with cirrhosis of the liver, can be monitored currently, but tests are not sensitive enough to detect the disease early.
Continuous positive airways pressure for obstructive sleep apnoea in adults
A machine that delivers air through a nasal mask worn during sleep can reduce daytime sleepiness and other symptoms associated with sleep apnea, but apnea patients are not always happy with the treatment, according to two new reviews of recent studies.
In apnea patients, the airway in the nose and throat periodically narrows or closes off during sleep, stopping breathing for seconds at a time. People with apnea usually snore and feel sleepy and less alert in the daytime. Some studies suggest apnea can contribute to high blood pressure, heart disease and stroke and may be a factor in traffic accidents.
Echinacea Does Not Prevent Colds, More Evidence Shows
The herbal supplement echinacea, when taken in certain forms, may help shorten the duration and severity of cold symptoms but is not effective for preventing the common cold, according to a systematic review of current evidence.
“Frankly, I would not actively recommend that consumers take echinacea preparations at the moment,” said lead study author Dr. Klaus Linde of the Center for Complementary Medicine Research, Technical University of Munich.
Contraceptive pills do not lead to major weight gain
Many women and clinicians worry that taking combination hormonal contraceptives will result in weight gain.
This anxiety deters some women from using this highly effective form of contraception. A systematic review of available data could however find no evidence of this effect. The results of this research are published in the latest update of The Cochrane Library.
Foot pain should not prevent obese from exercising
Obese people should seek immediate treatment for chronic foot and ankle problems that limit physical activity, the American College of Foot and Ankle Surgeons (ACFAS) urge.
“As our body weight increases, more load and stress are put on the feet,” foot and ankle surgeon Dr. Sean Wilson of Aspen Ortho & Rehab Specialists in West Allis, Wisconsin, and ACFAS spokesman, told Reuters Health.
Study confirms location of potential autism gene
In another step toward unraveling the origins of autism, a new study confirms that a region of chromosome number 3 seems to be involved in the development of the disorder.
There was no evidence, however, that mutations in one suspect gene increase the risk of autism.
Analyzing DNA from 31 members of a family of Northern European ancestry in which 7 individuals had autism or an autism-related disorder, researchers found that a portion of chromosome 3 appeared to be linked with the disorder.
Belgian military takes aim at obesity
The Belgian military has launched a slimming campaign for its forces whose obesity rate has swollen to 14 percent.
Incentives to practise sport and an awareness campaign were among elements of the plan to trim an obesity rate above the overall national average of 12 percent.
Anti-cholesterol drugs can cut sepsis risk: study
Cholesterol-lowering drugs called statins can reduce the risk of severe infection in patients suffering from heart disease or stroke, scientists said on Wednesday.
Statins lower cholesterol by inhibiting an enzyme that controls how much of this fat is produced in the body.
Chinese herbs no aid to SARS patients
Adding Chinese herbs to mainstream medical treatment of SARS did not save any lives but may have eased their misery a little, Chinese researchers reported on Tuesday.
A look at 12 separate trials of 654 patients with SARS who were treated with both Chinese medicines and Western therapy found no suggestion that either single herbs or combinations improved survival.
Anxious dads should prepare for caesarean -study
The reactions of fathers at a caesarean birth can affect the levels of fear, anxiety and pain their wives or partners experience, researchers said on Wednesday.
If men are more aware of what to expect before the operation, it could improve the experience for both the mother and father, the researchers suggest.
