Montreal, Canada, November 27, 2008 – Suffering from end-stage renal disease (ESRD), a growing number of patients at the Centre hospitalier de l'Université de Montréal (CHUM), have become the beneficiaries of a North American breakthrough: high efficacy hemodiafiltration (HDF).
An extracorporeal blood purification technique, HDF is indicated for ESRD patients. Since the HDF unit was introduced in CHUM's Nephrology section, preliminary results show a clear advantage of high efficacy HDF over conventional hemodialysis in several areas, including the following:
Almost a third of registered aged care nurses are considering quitting in the next year because of job stress, says a new University of Melbourne study.
The study, conducted by the Centre for Human Resource Management at the University of Melbourne and the Australian Nursing Federation finds Victoria's registered nurses in Victoria's aged care sector are "emotionally exhausted" and not committed to their workplace.
It cites excessive workloads, cost cutting, a hostile work environment and competing role demands as causing the stress.
Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye.
In a development that researchers say is likely to quell concerns about the value of costly computed tomography (CT) scans to diagnose coronary artery blockages, an international team led by researchers at Johns Hopkins reports solid evidence that the newer, more powerful 64-CT scans can easily and correctly identify people with major blood vessel disease and is nearly as accurate as invasive coronary angiography.
A noninvasive test that analyzes proteins in the urine can correctly identify patients whose transplanted kidneys are failing, according to a study appearing in the February 2009 issue of the Journal of the American Society Nephrology (JASN). The results might allow physicians to more accurately monitor transplant patients and to fine-tune the immunosuppressive therapies prescribed to prevent kidney rejection.
NEW YORK (Nov. 26, 2008) -- Retinal detachment, a condition that afflicts about 10,000 Americans each year, puts an individual at risk for vision loss or blindness. In a new study in today's issue of the New England Journal of Medicine, a leading ophthalmologist at NewYork-Presbyterian Hospital/Weill Cornell Medical Center writes, however, that a high probability of reattachment and visual improvement is possible by using one of three currently available surgical techniques.
The research council FORMAS, Sweden, has granted 5.9 million SEK to a new research project that will study the environmental fate and effects of the anti-viral drug Tamiflu on the development on influenza resistance.
Tamiflu is being stockpiled all over the world for use in fighting the next influenza pandemic. However, there are growing signs that influenza viruses may develope resistance to this vital pharmaceutical, because it is routinely prescribed for seasonal influenza.
It's a parents worst nightmare, a newborn baby going under the knife to repair a heart defect. If the baby survives, that's when the real work begins for parents. University of Alberta nursing professor Gwen Rempel has seen hundreds of babies on the brink as a former pediatric cardiology nurse; she wanted to find out just what parents go through.
ROCHESTER, Minn. -- Children whose eyes are misaligned and point outward are at significantly increased risk of developing mental illness by early adulthood, according to findings of a Mayo Clinic study published this month in Pediatrics (http://pediatrics.aappublications.org/cgi/content/full/122/5/1033), the official journal of the American Academy of Pediatrics.
PHILADELPHIA - A research team led by Mitchell Lazar, MD, PhD, Director of the Institute for Diabetes, Obesity, and Metabolism at the University of Pennsylvania School of Medicine, has discovered a key molecular partnership that coordinates body rhythms and metabolism.
OAK BROOK, Ill. – November 26, 2008 – The American Society for Gastrointestinal Endoscopy (ASGE) heralds the recent news of a decline in U.S. cancer deaths and incidence rates, with colorectal cancer among the top three cancers with significant declines. ASGE, representing the specialists in colorectal cancer screening, is excited by the report showing that colorectal cancer deaths among men and women dropped 4.3 percent per year between 2002 and 2005.
The Stowers Institute's Rong Li Lab has published findings that shed light on the ability of cells to adapt to disruptions to their basic division machineries – findings that may help explain how cancer cells elude the body's natural defense mechanisms or chemotherapy treatment. The work was published in the November 26 issue of Cell.
The Galápagos Islands, which provided impetus and inspiration for Charles Darwin's seminal work, "On the Origin of Species", are home to unique populations of reptiles. Since the time of man's first visit in the 16th century to this crucial incubator for evolutionary theory, the islands' native plants and animals have faced grave challenges, including severe pressures from introduced species, habitat destruction and predation by man himself.
In developing a model to explain the motion of atoms in a magnetic field, scientists have overcome a decades-old obstacle to understanding a key component of magnetic resonance.
The new understanding may eventually lead to better control of magnetic resonance imaging (MRI) and higher resolution MRI diagnoses.
