Predicting prostate cancer: Nanotechnology shows promise for more accurate prostate cancer screening and prognosis

A study in the emerging field of nanocytology could one day help men make better decisions about whether or not to undergo aggressive prostate cancer treatments. The prostate-specific antigen (PSA) test was once the recommended screening tool for detecting prostate cancer, but there is now disagreement over the use of this test because it can't predict which men with elevated PSA levels will actually develop an aggressive form of the disease.

Direct evidence of gadolinium deposition in brain tissues following contrast-enhanced MRI exams

New research finds direct evidence of gadolinium deposition in neuronal tissues following intravenous administration of gadolinium-based contrast agents used in MRI exams. "Despite evidence that trace amounts of gadolinium are depositing in neural tissues, there is currently no data to suggest that it's harmful to patients," notes one researcher.

How Long Does It Actually Take to Get Out of Shape?

SAPIEN valve, surgery equivalent at five years

Five-year data suggest that the SAPIEN transcatheter heart valve is a feasible option for patients with severe aortic stenosis deemed to be at high risk for open-heart surgery, though valve leakage was more common with the first-generation valve evaluated in this study than with surgery, according to new research.

Benefits seen for first-in-field brain shield used with TAVR: Device designed to deflect particles dislodged during valve replacement

An investigational device that deflects debris away from the brain during transcatheter aortic valve replacement seems to improve in-hospital safety outcomes and cognitive scores at discharge, according to preliminary findings from a small randomized study.

How To Lose Weight Fast - Let Your Body Do the Work for You

One of the quickest ways to lose weight is to cut down on the use of dietary carbohydrates for energy and to start burning your own body fat instead. Once you cut down on carbohydrates but keep protein intake up, your body will start to break down and burn body fat for the fuel that it needs.

No real cost difference between types of tests that look for heart disease

A study comparing the overall economics of computed tomographic angiography with functional stress tests for evaluating patients with symptoms suggestive of possible blocked coronary arteries found no significant differences in costs over three years.
