USPSTF Mammography Recommendations Will Result In Countless Unnecessary Breast Cancer Deaths Each Year
If cost-cutting U.S. Preventive Services Task Force (USPSTF) mammography recommendations are adopted as policy, two decades of decline in breast cancer mortality could be reversed and countless American women may die needlessly from breast cancer each year. ...more		 18 Nov 2009
How Cells Tolerate DNA Damage - MDC Researchers Identify Start Signal For Cell Survival Program
Cancer researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have gained new insights into how cells react to DNA damage. Dr. Michael Stilmann, Dr. Michael Hinz and Professor Claus Scheidereit have shown that the protein PARP-1, which detects DNA damage within seconds, activates the transcription factor NF-kappaB, a well-known regulator of gene expression. NF-kappaB triggers a survival program, which blocks programmed cell death. ...more		 17 Nov 2009
Acute Heart Attack Patients Receiving High Ionizing Radiation Dose
Acute heart attack patients received an average total dose of ionizing radiation equal to 725 chest X-rays from medical tests during their hospital stay, according to research presented at the American Heart Association's Scientific Sessions 2009. In the first large study to examine total radiation dosage in heart attack patients, researchers found those admitted to academic hospitals had a cumulative effective radiation dose of 14. ...more		 17 Nov 2009
Routine Mammograms Should Start At 50 Not 40 Says US Expert Panel
An independent medical expert panel that advises the US federal government on preventive and primary healthcare recommends against routine screening mammography in women aged 40 to 49 years and suggests instead that the decision to start regular screening before the age of 50 should be an individual one. ...more		 17 Nov 2009
Structured Reporting Software Creates Less Complete And Accurate Radiology Reports Than Free Text
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. ...more		 17 Nov 2009
