When it comes to meeting national health goals for physical activity, Mexican-Americans are the most active group in America and may benefit from exercise that researchers typically have not measured, according to research by scholars at the University of Chicago and Arizona State University. The new research, which used electronic devices to measure people's movement, challenges other studies based on self-reports that claimed non-Hispanic whites are most likely to be physically active. The researchers found that nearly 27 percent of Mexican-Americans met a national goal of getting at least 30 minutes of moderate activity five days a week or vigorous activity for 20 minutes at least three days a week;
Kidney dialysis patients often need repeated procedures, such as balloon angioplasty, to open blood vessels that become blocked or narrowed at the point where dialysis machines connect to the body. These blockages can impact the effectiveness of hemodialysis, a life-saving treatment to remove toxins from the blood when the kidneys are unable to do so. But a new FDA-approved stent graft can keep these access points open longer, reducing the number of procedures these patients may need, according to research from the University of Maryland published in the February 11, 2010, edition of the New England Journal of Medicine. "This is the first large-scale randomized study to find a therapy to be superior to the gold standard of balloon angioplasty.
Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge. In a study published online in Genome Research, researchers have developed a novel method of interpreting data from single-cell images to identify genetic interactions within biological networks, offering a glimpse into the future of high-throughput cell imaging analysis. For years, scientists have been peering through a microscope at cells as they change appearance in response to different treatments, yet data collection is arduous, largely conducted qualitatively by eye. However, recent technological advances have led to the development of high-throughput image screening methods that can produce extensive datasets of hundreds of different morphological features.
A UQ study will employ a unique mobile phone application to improve the "communicative fitness" and lifestyle of brain-injured patients. Led by Professor Linda Worrall from UQ's Clinical Centre for Research Excellence (CCRE) in Aphasia Rehabilitation, the study will be the first of its kind to use the technology in combining two complementary approaches to aphasia rehabilitation into one optimal treatment outcome. Aphasia, a language difficulty attributed to injury of the brain, usually from stroke, is estimated to affect 80, 000 Australians. It can vary from mild difficulties with finding words, or reading text, to not being able to understand what people are saying and being unable to speak.
Hospitals are beginning to use a new robotic catheter guidance system to treat abnormal heart rhythms. The robotic system "enhances a doctor's natural ability, and we believe it will contribute to improved procedural outcomes, " said Dr. David Wilber of Loyola University Health System, a nationally known researcher in heart rhythm disorders. The robotic system is used in a procedure, called an ablation, which treats irregular heartbeats such as atrial fibrillation. The treatment destroys small areas of heart tissue that trigger irregular heartbeats. Atrial fibrillation, often called A-fib, is the most common form of irregular heartbeat.
Agendia Receives New York State Laboratory Permit And Laboratory Accreditation By College Of American Pathologists
Agendia, a world leader in molecular cancer diagnostics, announced that it has received the Clinical Laboratory Permit from the New York State Department of Health. The New York State permit allows the company to receive commercial samples of MammaPrint, its FDA-cleared breast cancer recurrence test. With this latest permit, Agendia has now obtained all major U.S. clinical laboratory licenses. In addition, the College of American Pathologists (CAP) has accredited Agendia's CLIA regulated laboratory in Huntington Beach, CA. "The New York State permit is often recognized as one of the most difficult to obtain. Together with our CAP accreditation, CLIA compliance, and FDA-clearance for MammaPrint, we give patients and physicians the confidence they need while making important treatment decisions, " said Dr.
