Rapidly, but expressively and with amazing ease, the guitarist's fingers move over the strings on the neck of the instrument. His fingertips move up and down and a vibrato resonates. From the guitar a cable leads to a laptop, which records the virtuoso performance in minute detail. The computer registers each vibrato, each bend precisely and almost instantaneously. Afterwards the guitarist can play back the digital recording and process it on a computer.
New research reports a high prevalence of vitamin D insufficiency and deficiency among patients with psoriatic arthritis. Seasonal variation in vitamin D levels was not observed in patients in southern or northern locations. The findings published today in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR), also show no association between disease activity and vitamin D level.
Researchers have discovered that obese adults undergoing surgery are less frequently developing respiratory insufficiency (RI) and adult respiratory distress syndrome (ARDS), and that when they do, they are less likely to have fatal outcomes. The researchers say they have several theories of how obesity protects patients from mortality associated with RI/ARDS, and pinpointing the protective mechanism could help them develop interventions to help non-obese patients avoid adverse outcomes.
SAN DIEGO, CA – The onset of osteoarthritis may be related to a loss of knee motion after reconstructive ACL surgery, as noted in new research presented at the American Orthopaedic Society for Sports Medicine's Annual Meeting in San Diego, California, July 7-10, 2011. Patients who showed motion limitations after surgery were more likely to develop arthritic changes in the knee.
Stocks of seabed-living fish in the Firth of Clyde have reached their highest level since 1927 – according to research by academics at the University of Strathclyde.
However, the report, produced by Professor Mike Heath and Dr Douglas Speirs of the University's Marine Population Modelling Group, shows that while fish are actually more abundant than ever, the majority are too small to be landed.
For patients suffering from epidermolysis bullosa (EB), a hereditary skin disease, even a gentle touch is extremely painful. Now Dr. Li-Yang Chiang, Dr. Kate Poole and Professor Gary R. Lewin of the Max Delbrück Center for Molecular Medicine (MDC) in Berlin-Buch have discovered the causes underlying this disease. Due to a genetic defect, individuals with EB cannot form laminin-332, a structural molecule of the skin that in healthy individuals inhibits the transduction of tactile stimuli and neuronal branching (Nature Neuroscience, doi: 10.1038/nn.2873)*.
An analysis of heart disease and stroke statistics collected in 192 countries by the World Health Organization (WHO) shows that the relative burden of the two diseases varies widely from country to country and is closely linked to national income, according to researchers at the University of California, San Francisco.
Reporting in the journal Circulation, the UCSF scientists found that developing countries tend to suffer more death and disability by stroke than heart disease – opposite the situation in the United States and other countries with higher national incomes.
CHICAGO -- New research published online today in Circulation Research found that injections of adult patients' own CD34+ stem cells reduced reports of angina episodes and improved exercise tolerance time in patients with chronic, severe refractory angina (severe chest discomfort that did not respond to other therapeutic options).
An injection of stem cells into the heart could offer hope to many of the 850,000 Americans whose chest pain doesn't subside even with medicine, angioplasty or surgery, according to a study in Circulation Research: Journal of the American Heart Association.
Patients who received the new treatment reported half as many chest pain episodes and improved exercise capability compared to those who received a placebo.
COLUMBIA, Mo. –Children who witness domestic violence are more likely to be in abusive intimate relationships and experience psychological problems such as post traumatic stress disorder (PTSD) in adulthood, according to the Centers for Disease Control and Prevention. A University of Missouri researcher has found that certain protective factors foster resilience and increase the likelihood that the cycle of violence will end for women who, as children, were exposed to their mothers' battering.
OTTAWA, July 7, 2011 – Family doctors are reluctant to disclose identifiable patient information, even in the context of an influenza pandemic, mostly in an effort to protect patient privacy. A recently published study by Dr. Khaled El Emam the Canada Research Chair in Electronic Health Information at the University of Ottawa and the Children's Hospital of Eastern Ontario Research Institute recently found that during the peak of the H1N1 pandemic in 2009, there was still reluctance to report detailed patient information for public health purposes.
WOONSOCKET, R.I. – July 7, 2011 – As the nation seeks to expand health care coverage to more citizens without adding burdensome costs, researchers from Harvard University, Brigham and Women's Hospital and CVS Caremark reported that preventative health care may be significantly less costly than previously thought, due to expanded use of cost-effective generic medications for the treatment and prevention of chronic disease.
Pupils with special needs and teachers in mainstream schools in the UK are often the victims of a "one size fits all" approach to schooling and education, a leading academic has claimed.
Professor Paul Cooper, a chartered psychologist and professor of education at the University of Leicester, said pupils with social, emotional and behavioural problems (SEBD) are at particular risk of under-achieving because schools are frequently ill-equipped to handle their problems.
Identifying a suitable donor for leukemia and lymphoma patients who need bone marrow transplants may be far easier now that results of two clinical trials show transplant results with half-matched bone marrow or umbilical cord blood are comparable to fully matched tissue, thanks in large part to the availability of effective antirejection drugs and special post-transplant chemotherapy. The finding means that nearly all patients in need of a transplant can find donors, according to Johns Hopkins scientists who participated in the trials.
NEW YORK, NY (July 6, 2011) - A new study has found that most patients undergoing biopsy of the small intestine do not have the recommended number of samples to diagnose celiac disease. The study, published in the July 2011 issue of Gastrointestinal Endoscopy, analyzed a national database of biopsy specimens maintained by Caris Life Sciences (Irving, TX). More than 100,000 patients had a biopsy of the small intestine, but only 35 percent of them had at least four samples taken, the number recommended by professional guidelines.
