Noninvasive diagnostics may offer alternative to liver biopsy for assessing liver fibrosis

Patients who are evaluated for liver diseases such as hepatitis C (HCV) are typically recommended for liver biopsy to determine the extent of disease progression. For patients who question whether less invasive testing is available, clinicians now have alternatives options to consider. Elastography and serum markers are two such diagnostic options reviewed in an editorial published in the June issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.

New study raises doubts about benefits of ezetimibe in patients suffering from high LDL cholesterol

More than 42 million Americans suffer from high cholesterol, and 63 million more have borderline high cholesterol. Over time, high levels of LDL cholesterol, often called "bad cholesterol," build up along the walls of arteries and blood vessels, a process called atherosclerosis, which can lead to a high risk of heart disease, stroke and heart attack.

Treadmill test helps predict lifetime risk of cardiovascular disease in middle-age people

In two separate studies, UT Southwestern Medical Center researchers have found that how fast a middle-age person can run a mile can help predict the risk of dying of heart attack or stroke decades later for men and could be an early indicator of cardiovascular disease for women.

Super-resolution microscopy technique reveals how and why cell's defenses fail against plague

Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli.

Bedside screening tool can help diagnose acute aortic dissection

The most lethal and sudden cardiovascular event can be the toughest for doctors to diagnose. But a study by the University of Michigan Cardiovascular Center shows new guidelines are effective for determining who's most likely suffering from an aortic dissection, which is tearing in the lining of the body's largest blood vessel.

Proton radiography imaging helps lower radiation dosage to pediatric cancer patients

Proton radiography imaging used prior to and during proton treatments for pediatric cancer patients provides for more accurate treatment delivery and a lower dose of radiation compared to standard diagnostic X-rays and cone beam CT, according to a study presented today at the Cancer Imaging and Radiation Therapy Symposium in Atlanta. The symposium is co-sponsored by the American Society for Radiation Oncology (ASTRO) and the Radiological Society of North America (RSNA).
