Defibrillator Survey Raises Workplace Cardiac Arrest Concerns
Date: Feb-20-2013More than half of British businesses do not have a defibrillator, show poll results released this week - despite the impact the device has on cardiac arrest survival rates. The Institution of Occupational Safety and Health (IOSH) commissioned a survey of 1,000 business decision-makers across the UK and found that 513 did not have the lifesaving equipment at work. Almost two thirds of those who said 'no' also come from medium to very large companies...
Results From Cogane™ In Parkinson's Disease Clinical Trial
Date: Feb-20-2013Phytopharm plc (PYM: London Stock Exchange) ("Phytopharm", the "Group" or the "Company") have announced the results of the Phase II, randomised, double blind, placebo controlled, dose-ranging trial of Cogane™ in unmedicated patients with early-stage Parkinson's disease ("CONFIDENT-PD"). Analysis of the headline results indicated that Cogane™ had no beneficial effects on patients' symptoms measured by the primary or secondary endpoints in the study...
Women With Polycystic Ovary Syndrome Seem To Have Higher Risk Of Heart Attack And Stroke
Date: Feb-20-2013A syndrome common in women of reproductive age may place them at greater risk for hardening of the arteries, which predisposes them to heart attack and stroke, according to research published Feb. 15 in the American Journal of Physiology, Endocrinology and Metabolism. Glucose can stimulate an inflammatory process that allows white blood cells to enter the artery walls and attract cholesterol. Researchers studied 18- to 40-year-old women, lean and obese, with polycystic ovary syndrome and weight-matched controls...
Study Of Blood Plasma Improves Our Understanding Of Thrombosis, Aneurysms And Arteriosclerosis
Date: Feb-20-2013The results are significant because they can help to improve our understanding of medical conditions, such as thrombosis, aneurysms and arteriosclerosis. The research team is publishing its results in Physical Review Letters and the American Physical Society has highlighted the work on its Physics website*, placing it on the Focus List of important physics news. Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only filmmakers are aware of...
Artificial Brain System
Date: Feb-20-2013This technological prowess was made possible by the development of a "simplified artificial brain" that reproduces certain types of so-called "recurrent" connections observed in the human brain. The artificial brain system enables the robot to learn, and subsequently understand, new sentences containing a new grammatical structure. It can link two sentences together and even predict how a sentence will end before it is uttered. This research has been published in the Plos One journal...
During Recurrent Glioblastoma Multiforme Surgery, 5-ALA Fluorescence Guides Resection
Date: Feb-20-2013Neurosurgeons from UC San Francisco describe the use of 5-aminolevulinic acid (5-ALA) fluorescence in guiding resection of recurrent glioblastoma multiforme (GBM). Ingestion of 5-ALA by a patient before surgery leads to fluorescence of tumor cells intraoperatively in response to certain wavelengths of light. This can provide information not necessarily available through magnetic resonance imaging (MRI), the standard mode of imaging used to detect primary and recurrent GBMs. The additional information provided by 5-ALA fluorescence can guide surgeons in the treatment of individual cases...
Spinal Polymer Implants Coated With Bioactive Film To Improve Bonding With Bone
Date: Feb-20-2013Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film. The discovery should improve the success rate of such implants - which are often used in spinal surgeries. The polymer used in these implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing against surrounding tissues, which can lead to medical complications and the need for additional surgeries...
National Screening Benchmarks For Finding Polyps During A Colonoscopy Might Be Too Low
Date: Feb-20-2013Current national guidelines provide benchmarks regarding the number of polyps physicians should detect, on average, during a colonoscopy. Recent studies at Mayo Clinic's campus in Florida suggest these benchmarks may be too low. Their study, in the online issue of Gastrointestinal Endoscopy, found that use of high-definition imaging tools in 2,400 individuals undergoing a screening colonoscopy at the clinic led to an adenoma detection rate (ADR) of 25 percent in women and 41 percent in men...
Word Of Mouth Trumps Online Ratings When Families Select A Child's Doctor
Date: Feb-20-2013Numerous websites are available to rate just about any service or product: restaurant food, hotel service and even a pediatrician's care. However, a new poll from the University of Michigan shows that only 25 percent of parents say they consider doctor rating websites very important in their search for a child's physician. But the latest University of Michigan Mott Children's Hospital National Poll on Children's Health did show that younger parents, those under 30, were more likely to say that online doctor ratings are very important...
Halting Metastasis Of Colon Cancer
Date: Feb-20-2013A Basque research consortium has managed to halt the progress of colon cancer and its metastasis in the liver in an experimental model with mice. This advance, that may open a new path for the future treatment of such pathologies, has been achieved by creating molecules which interfere with the adhesion of tumour cells to other cells of the organism. In this way, the molecules halt both the growth of the tumour and the dissemination of the tumour to and its proliferation in other organs...
