The system's transducers, which can be easily operated with one hand, transmit ultrasound images via radio waves to the screen on the base console. The elimination of cables is particularly helpful in operations or during invasive procedures in which the needle visualization needs to be monitored using ultrasound technology. That's because transducer cables can obstruct the people who operate the machines, and despite their sterile protective coverings, the cables can pose a risk in terms of infections. The wireless Acuson Freestyle system transducers function reliably up to three meters from the console and are equipped with remote control buttons for adjusting the image settings. To make wireless data transmission possible, Siemens engineers sharply reduced the amount of data that must be transferred between the transducer and the console. http://medicalxpress.com/news/2013-05-wireless-ultrasound-transducers-physicians.html Other Mon, 20 May 2013 08:00:01 EST news288252886 A major new report on a procedure that aims to reduce the duration of care proceedings for children has found it made no significant difference to what happened in court, and cases lasted just as long regardless of whether they involved the 'pre-proceedings' process. http://medicalxpress.com/news/2013-05-pre-proceedings-length-proceedings-cases-court.html Health Mon, 20 May 2013 07:50:03 EST news288253812 New research undertaken on the streets of Richmond and Abbotsford has revealed increasing health risks for people who inject drugs and significant community concern over the impact of injecting in public areas. http://medicalxpress.com/news/2013-05-reveals-impact.html Health Mon, 20 May 2013 07:50:02 EST news288252792 (Medical Xpress)—Patients with the most severe and dangerous form of chronic anorexia are more likely to make a significant improvement towards recovery and stay in therapy if traditional psychological treatments are re-focused from weight gain to quality of life issues. http://medicalxpress.com/news/2013-05-rethinking-treatment-goals-results-untreatable.html Psychology & Psychiatry Mon, 20 May 2013 07:40:05 EST news288252713 (Medical Xpress)—Scientists at King's College London have discovered that Vitamin D has the potential to significantly reduce the symptoms of asthma.

Using data from the National Institutes of Health (Heart, Lung, and Blood Institute)-funded Wisconsin Sleep Cohort Study, which has been following approximately 1,500 people since 1988, researchers found that patients who had asthma were 1.70 times (95% CI=1.15-2.51) more likely to develop sleep apnea after eight years. http://medicalxpress.com/news/2013-05-potential-apnea-asthma.html Sleep apnea Sun, 19 May 2013 14:10:01 EST news288172668 A new study looking at sleep-disordered breathing (SDB) and markers for Alzheimer's disease (AD) risk in cerebrospinal fluid (CSF) and neuroimaging adds to the growing body of research linking the two. http://medicalxpress.com/news/2013-05-apnea-alzheimer-linked.html Alzheimer's disease & dementia Sun, 19 May 2013 14:00:05 EST news288172741 Scientists at Johns Hopkins have turned their view of osteoarthritis (OA) inside out. Literally. Instead of seeing the painful degenerative disease as a problem primarily of the cartilage that cushions joints, they now have evidence that the bone underneath the cartilage is also a key player and exacerbates the damage. In a proof-of-concept experiment, they found that blocking the action of a critical bone regulation protein in mice halts progression of the disease. http://medicalxpress.com/news/2013-05-theory-genesis-osteoarthritis-successful-therapy.html Arthritis & Rheumatism Sun, 19 May 2013 13:10:10 EST news288172115 In their quest to learn more about the variability of cells between and within tissues, biomedical scientists have devised tools capable of simultaneously measuring dozens of characteristics of individual cells. These technologies have led to new challenges, however, as scientists now struggle with how to make sense of the resulting trove of data. Now a solution may be at hand. Researchers at Columbia University and Stanford University have developed a computational method that enables scientists to visualize and interpret "high-dimensional" data produced by single-cell measurement technologies such as mass cytometry. The method, published in the online edition of Nature Biotechnology, has particular relevance to cancer research and therapeutics. http://medicalxpress.com/news/2013-05-tool-complex-dimensional-images.html Medical research Sun, 19 May 2013 13:10:01 EST news288172425 The devastating effect of Alzheimer's disease on bilingual people has been thrown into focus in Canada, where the sudden loss of a second language can leave sufferers feeling like strangers in their own country. http://medicalxpress.com/news/2013-05-alzheimer-bilingual-victims-stranded-canada.html Alzheimer's disease & dementia Sun, 19 May 2013 11:10:01 EST news288173217
