Potassium citrate effective for prevention and treatment of osteoporosis: Study

The Western diet creates an acidic environment in the body that removes calcium from bones and may contribute to the development of osteoporosis. Healthy adults who consume the standard US diet sustain a chronic, low-grade state of acidosis that worsens with age as kidney function declines, limiting urinary acid excretion. Reto Krapf, MD (University of Basel, in Bruderholz/Basel, Switzerland) and colleagues designed a study to see if daily alkali as potassium citrate supplement tablets might neutralize these effects.

Study reveals very high cumulative estimated effective doses to patients undergoing MPI

Multiple testing with the cardiac diagnostic imaging technique of myocardial perfusion imaging is common, and in many patients is associated with a high cumulative estimated radiation dose, according to a study in the November 17 issue of JAMA.

Iron in plaque may predict risk of myocardial infarction

Plaque in a heart artery looks threatening, but cardiologists know that many of these buildups will not erupt, dislodge and block a vessel, causing a heart attack that can be fatal. Some will, however, and the challenge is to figure out atherosclerotic plaque that is dangerous and treat or remove it.

FDA identifies promising steps to enhance safety of CT scans

The U.S. Food and Drug Administration has been investigating reports that patients undergoing computed tomography (CT) brain perfusion scans were accidently exposed to excess radiation. The FDA found that when properly used, the CT scanners did not malfunction. Instead, it is likely that the improper use of the scanners resulted in these overdoses. However, the FDA has identified a series or promising steps to enhance the safety of these procedures. These steps could reduce the likelihood of radiation overexposure in the event of improper use of the CT scanners.

ECRI Institute introduces CT Radiation Dose Safety Review service to reduce risk of excessive radiation

Keeping radiation dose in check is a top safety concern for today's hospitals, particularly in computed tomography, which has undergone some significant technological advances in the last ten years. The down side is that CT delivers some of the highest radiation doses in diagnostic radiology.

Screening heavy smokers for lung cancer reduces chance of death, federal study finds

The Boston Globe: "Screening heavy smokers with sophisticated medical scanners modestly reduced their chance of dying from lung cancer, according to a federal study released yesterday that provides the first convincing evidence that testing could reduce the toll from the leading cause of cancer deaths. The preliminary findings from the National Cancer Institute were based on a gold-standard study that randomly assigned 53,000 current or former smokers without symptoms to be screened with a CT scanner or standard chest X-ray.

More effective therapeutic exercises underutilized in treatment of chronic neck pain

Duke University and University of North Carolina (UNC) researchers report in the November issue of Arthritis Care & Research that narcotics and diagnostic testing are overused in treating chronic neck pain. Their findings indicate clinicians may overlook more effective treatments for neck pain, such as therapeutic exercise. According to reviews cited in the study, evidence to support the effectiveness of therapeutic exercise in treating chronic neck pain is good, yet only 53% of subjects were prescribed such exercise.

Eating whole grains and limiting refined grains reduce body fat

People who consume several servings of whole grains per day while limiting daily intake of refined grains appear to have less of a type of fat tissue thought to play a key role in triggering cardiovascular disease and type 2 diabetes, a new study suggests. Researchers at the Jean Mayer USDA Human Nutrition Researcher Center on Aging (USDA HNRCA) at Tufts University observed lower volumes of visceral adipose tissue (VAT) in people who chose to eat mostly whole grains instead of refined grains.
