ROCHESTER, Minn. -- Obese teenagers who lose weight are at risk of developing eating disorders such as anorexia nervosa and bulimia nervosa, Mayo Clinic researchers imply in a recent Pediatrics article. Eating disorders among these patients are also not being adequately detected because the weight loss is seen as positive by providers and family members. In the article, Mayo Clinic researchers argue that formerly overweight adolescents tend to have more medical complications from eating disorders and it takes longer to diagnose them than kids who are in a normal weight ...

A new analysis published online Sept. 9 in Cancer confirms the need for greater use of annual mammography in women ages 40-49 as recommended by the American Cancer Society, American Congress of Obstetricians and Gynecologists (ACOG), American College of Radiology and Society of Breast Imaging for all women 40 and older. It also confirms that, even with new therapeutics and protocols for treating breast cancer, regular mammography screening is still the best way to significantly reduce breast cancer deaths. The study, which involved 7,301 patients, found that 71 percent ...

SALT LAKE CITY -- University of Utah electrical engineers have developed a network of wireless sensors that can detect a person falling. This monitoring technology could be linked to a service that would call emergency help for the elderly without requiring them to wear monitoring devices. For people age 65 and older, falling is a leading cause of injury and death. Most fall-detection devices monitor a person's posture or require a person to push a button to call for help. However, these devices must be worn at all times. A 2008 study showed 80 percent of elderly adults ...

Music has an uncanny way of bringing us back to a specific point in time, and each generation seems to have its own opinions about which tunes will live on as classics. New research suggests that young adults today are fond of and have an emotional connection to the music that was popular for their parents' generation. "Music transmitted from generation to generation shapes autobiographical memories, preferences, and emotional responses, a phenomenon we call cascading 'reminiscence bumps,'" explains psychological scientist and lead researcher Carol Lynne Krumhansl of ...

MAYWOOD, Il. – A Loyola University Chicago Stritch School of Medicine study suggests that omega-3 fish oil might help protect against alcohol-related dementia. Previous studies have shown that long-term alcohol abuse increases the risk of dementia. The Loyola study found that in the brain cells of rats exposed to high levels of alcohol, a fish oil compound protected against inflammation and cell death. The study by Michael A. Collins, PhD, and colleagues was reported Sept. 8 at the 14th Congress of the European Society for Biomedical Research on Alcoholism in Warsaw. An ...

Barcelona, Spain: Virtual observation of patients taking their prescribed TB medication, could prove an effective technique for ensuring patients effectively complete their course of treatment. The research will be presented today (8 September 2013) at the European Respiratory Society (ERS) Annual Congress. The new study suggests an alternative method to directly observed treatment (DOT), which is recommended by the World Health Organization. Directly observing treatments is often time consuming for a patient and is resource intensive for outreach projects, which seek ...

Barcelona, Spain: Living close to a busy road is associated with a higher risk of death in people with bronchiectasis. A new study, presented at the European Respiratory Society (ERS) Annual Congress in Barcelona today (8 September 2013), has added to the growing body of evidence demonstrating the damaging effects of road-side pollution. Bronchiectasis is a condition in which the airways of the lungs become abnormally widened, leading to a build-up of excess mucus. It can be caused by cystic fibrosis (CF), and experts usually categorise the condition as cases either ...

Barcelona, Spain: First trial to compare e-cigarettes with nicotine patches shows comparable success in helping smokers to quit. The first ever trial to compare e-cigarettes with nicotine patches has found that both methods result in comparable success in quitting, with roughly similar proportions of smokers who used either method remaining abstinent from smoking for six months after a 13 week course of patches or e-cigarettes. The study, presented today (8 September 2013) at the European Respiratory Society (ERS) Annual Congress in Barcelona, Spain and published in ...

Barcelona, Spain: Results of a new study suggest that three new diagnostic tests could each be used to successfully diagnose drug resistance in tuberculosis (TB) patients in a quarter of the time taken by the current method. The research, presented today (8 September 2013) at the European Respiratory Society's Annual Congress in Barcelona, has provided evidence that each test could be used as an effective alternative to standard testing, increasing the possibilities open to clinicians. Drug susceptibility tests are carried out in people with active TB in order to ...

'Eat less salt' is a mantra of our health-conscious times and is seen as an important step in reducing heart disease and hypertension. Too much salt in the diet – and specifically sodium – is widely acknowledged as a major risk factor for high blood pressure however, scientists have found that salt's other oft-overlooked constituent chloride might also play an important role. A study by researchers at the University of Glasgow has revealed that low chloride levels in the blood is an independent indicator of mortality risk in people with hypertension. The role of chloride ...

DNA is the blueprint for life. Could it also become the template for making a new generation of computer chips based not on silicon, but on an experimental material known as graphene? That's the theory behind a process that Stanford chemical engineering professor Zhenan Bao reveals in Nature Communications. Bao and her co-authors, former post-doctoral fellows Anatoliy Sokolov and Fung Ling Yap, hope to solve a problem clouding the future of electronics: consumers expect silicon chips to continue getting smaller, faster and cheaper, but engineers fear that this virtuous ...

Two NASA satellites and one of NASA's Global Hawk aircraft got good looks at Gabrielle when it weakened from a tropical storm to a depression. Although Gabrielle is now a remnant low pressure area, there are a couple of other developing low pressure areas in the Atlantic Ocean basin to keep an eye on. As part of NASA's Hurricane Severe Storms Sentinel mission known as HS3, two of NASA's Global Hawks have been investigating Gabrielle and are gathering data over its remnants. Global Hawk 871 and 872 have been gathering data on Gabrielle this week and are expected to fly ...

CAMBRIDGE, MA -- The future of satellite technology is getting small — about the size of a shoebox, to be exact. These so-called "CubeSats," and other small satellites, are making space exploration cheaper and more accessible: The minuscule probes can be launched into orbit at a fraction of the weight and cost of traditional satellites. But with such small packages come big limitations — namely, a satellite's communication range. Large, far-ranging radio dishes are impossible to store in a CubeSat's tight quarters. Instead, the satellites are equipped with smaller, less ...
