The Siemens SOMATOM Definition Flash can image ten times as fast as other clinical units, with an up to 90% dose reduction in radiation compared to conventional imaging. The scanner’s dual source technology allows NYU Langone Medical Center to provide new levels of patient care, especially for trauma, pediatric, cancer and cardiac patients.
A Dalhousie researcher is studying methods to help alleviate fears of needles.
The routine prescription of extended-release niacin, a B vitamin (1,500 milligrams daily), in combination with traditional cholesterol-lowering therapy offers no extra benefit in correcting arterial narrowing and diminishing plaque buildup in seniors who already have coronary artery disease, a new vascular imaging study from Johns Hopkins experts shows.
Between 1999 and 2006, the prevalence of adults in the U.S. with high levels of LDL cholesterol, the “bad” cholesterol, decreased by about one-third, according to a study in the November 18 issue of JAMA. But a high percentage of adults still are not being screened or treated for high cholesterol levels.
Patients with heart disease in Norway, a country with no fortification of foods with folic acid, had an associated increased risk of cancer and death from any cause if they had received treatment with folic acid and vitamin B12, according to a study in the November 18 issue of JAMA.
An analysis of patients with a syndrome similar to the genetic disorder, neurofibromatosis type 1, indicates that diagnosis may be difficult because of shared clinical findings, such as certain pigmentary characteristics, according to a study in the November 18 issue of JAMA.

The data will be presented in the Late Breaking Science session at the American Heart Associations Scientific Sessions in Orlando, Fla.
Results of a Mayo Clinic study show the incidence of stroke or mini-stroke related to a coronary angioplasty remained steady over a 15-year period. Researchers say this is good news because physicians now are performing the artery-opening procedure on older patients who are sicker and need more complicated treatment.
Pooling results from 21 studies, involving 622,381 men and women, researchers at Johns Hopkins have affirmed that migraine headaches are associated with more than twofold higher chances of the most common kind of stroke: those occurring when blood supply to the brain is suddenly cut off by the buildup of plaque or a blood clot.
As many software companies work to create programs that will give uniform structure to the way radiological test results are reported, a new study by researchers at Wake Forest University School of Medicine shows that such a system does not improve, but rather decreases the completeness and accuracy of the reports.
Pooled results from three separate clinical trials of flibanserin, a drug originally created as an antidepressant, show it is effective in treating women with acquired hypoactive sexual desire disorder. These trials were the first ever to test a therapy that works at the level of the brain to enhance libido in women reporting low sexual desire.

Four macaque monkeys that received injections of genes for a protein called follistatin into upper leg muscles experienced pronounced and durable increases in muscle size and strength and no adverse effects, the Muscular Dystrophy Association (MDA) announced today. The findings could have implications particularly for injured and aging people worldwide; and for tens of millions experiencing muscle loss associated with cancer, AIDs and muscle diseases.
Scientists at a group of 11 research centers in China are reporting for the first time assembly of the largest-ever collection of data about the proteins produced by genes in a single human organ. Their focus was the liver, and their massive database in both protein and transcript levels could become a roadmap for finding possible new biomarkers and treatments for liver disease.
Despite a current suggestion that patients with acute respiratory distress syndrome be positioned lying face down while receiving mechanical ventilation, study results indicate that this positioning does not significantly lower the risk of death compared to similar patients positioned lying face up during ventilation, according to a study in the November 11 issue of JAMA.
Lipid assessment in vascular disease can be simplified by measuring either total and HDL cholesterol levels or apolipoproteins, without the need to fast and without regard to triglyceride levels, according to a study in the November 11 issue of JAMA.
These days, saving a little money here and there is all the rage. Even small changes – carpooling to work or making coffee at home – can really add up. But when it comes to cutting back on hair care, many people might be hesitant to make significant changes for fear that it could impact their looks and the health of their hair. That’s where a dermatologist can help.
For many people, diet and exercise help keep them looking and feeling healthy. But even those who work hard on staying in shape might have a hard time shaking stubborn love handles or lower belly fat, which can bulge through clothing like a neon sign. While the market for getting rid of unwanted fat has grown over the years to include stomach stapling and behavioral techniques, there is still a demand for procedures that can reduce areas of localized fat safely and effectively.
Finding the right skin care routine starts with understanding the unique needs of your skin type. For example, people with dry skin can benefit from applying moisturizer several times a day; whereas, those with oily skin might need to apply a lightweight moisturizer only once a day, if at all. Customization is key, and dermatologists can help people of all ages and skin types select products based on their individual skin care needs.
A recent study found a 27-percent decrease in heart attacks from citizens of Starkville, Miss., three years after the city passed a smoking ban in public places.
After one year, a low-calorie, low-fat diet appears more beneficial to dieters’ mood than a low-carbohydrate plan with the same number of calories, according to a report in the November 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
In an advance that could one day enable surgeons to reconstruct and restore function to damaged or diseased penile tissue in humans, researchers at the Wake Forest Institute for Regenerative Medicine have used tissue engineering techniques to completely replace penile erectile tissue in rabbits. This is the most complete replacement of penile erectile tissue to date and suggests the possibility of using the same approach for men with erectile dysfunction or conditions that require reconstruction, including penile cancer and congenital abnormalities.
Becoming “hard of hearing” is a standard but unfortunate part of aging: A syndrome called age-related hearing loss affects about 40 percent of people over 65 in the United States, and will afflict an estimated 28 million Americans by 2030.
Of the many characteristic traits a drug can have, one of the most desirable is the ability for a drug to be swallowed and absorbed into the bloodstream through the gut. Some drugs, like over-the-counter aspirin, lend themselves to this mode of delivery and are trivial to take. They can be pressed into a pill and swallowed. Other drugs cannot be swallowed and must be administered instead through more complicated routes. Insulin, for instance, must be injected.
Dana Filoti of the University of New Hampshire will present thin films of silver and copper she has developed that can kill bacteria and may one day help to cut down on hospital infections. The antimicrobial properties of silver and copper have been known for centuries -- last year, the U.S. Environmental Protection Agency officially registered copper alloys, allowing them to be marketed with the label "kills 99.9% of bacteria within two hours." Copper ions are known to penetrate bacteria and disrupt molecular pathways important for their survival.
Amid the on-going controversy over the safety of mercury-containing dental fillings, a University of Saskatchewan research team has shed new light on how the chemical forms of mercury at the surface of fillings change over time.
New Mayo Clinic research has found that robotic surgery for vaginal prolapse dramatically reduces patient hospital stay and recovery time.
When it comes to vitamin D, consumers are bombarded with mixed messages about the best source for this essential nutrient. While some may argue that small doses of intentional sun exposure are safe, dermatologists point out that the risk of developing skin cancer from ultraviolet (UV) radiation far outweighs the benefit of stimulating vitamin D production – particularly when enriched foods and supplements are safe and effective sources of this vitamin.
A small group of patients with severe Graves’ eye disease experienced rapid improvement of their symptoms—and improved vision—following treatment with the drug rituximab. Inflammation around their eyes and damage to the optic nerve were significantly reduced. The same patients had not previously responded to steroids, a common treatment for Graves’ eye disease.
A compound already used to treat pneumonia could become a new therapy for an inherited muscular wasting disease.

Barriers to the adoption of sanding tools that lead to healthier environments include productivity, work quality, and perceptions of benefits and risks.
In a newly-published special supplement, the Journal of Cardiovascular Nursing calls for new hospital policies to prevent and treat venous thromboembolism (VTE), a major cause of death and disability in hospitals throughout the world. Lippincott Williams & Wilkins (LWW) is publishing the supplement to bring attention to VTE, a disease that includes both the common medical condition of deep vein thrombosis and its most serious complication, pulmonary embolism, which accounts for 10% of hospital deaths annually.
Declining kidney function is linked to a higher risk of heart failure, heart attack, peripheral arterial disease, and early death in individuals with or without kidney disease, according to a pair of studies appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN).
Results of a long QT syndrome (LQTS) study published in the current issue of Circulation play an important role in understanding genetic testing’s role in diagnosing disease, according to the senior author, Michael Ackerman, M.D., Ph.D. A pediatric cardiologist at Mayo Clinic, Dr. Ackerman directs Mayo’s Long QT Syndrome Clinic and is the director of the Mayo Clinic Windland Smith Rice Sudden Death Genomics Laboratory.
A new study indicates dentists can play a potentially life-saving role in health care by identifying patients at risk of fatal heart attacks and referring them to physicians for further evaluation.
Bone strength and heart health are two of the most important health issues for women. One out of every two women will have an osteoporosis-related fracture in her lifetime and more than 50 million women have blood cholesterol levels high enough to pose a risk for heart disease. Now there is a new product available to help address both of these issues at the same time.
Pesticides, unfortunately, are not without risk to those who labor in the fields and orchards, planting, tending and harvesting crops -- and this risk increases for Mexican farmworkers.
Stereotactic radiosurgery (SRS) offers a less invasive way to eliminate tremors caused by Parkinson’s disease and essential tremor than deep brain stimulation (DBS) and radiofrequency (RF) treatments, and is as effective, according to a long-term study presented November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).
