CT colonoscopy has 90 percent agreement rate with optical colonoscopy

Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths), according to a new study by researchers from the University of Wisconsin Hospital and Clinics in Madison, WI.

Simple blood test for BNP levels predictive of higher in-hospital mortality rates for heart failure patients

A simple blood test, beyond standard lab tests, taken at hospital admission strongly predicted in-hospital mortality risk for heart failure patients and may be useful in helping doctors decide which patients need higher-level monitoring and more intensive treatment.
