Smoking increases brain lesions and brain shrinkage in MS
People who smoke and have multiple sclerosis (MS) may be at increased risk of brain shrinkage and increased brain lesions related to the disease, revealed by researchers.

Prostatectomy effective in men with aggressive prostate cancer
Prostate surgery prostatectomy is found very effective in preventing death in men with aggressive prostate cancers, revealed by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC), Cleveland Clinic and the University of Michigan.

Routine MRI scan to evaluate breast cancer is challenged
Women with newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment, revealed by researchers.

CT colonography better for colorectal cancer screening
Computed tomographic (CT) colonography may offer patients at increased risk of colorectal cancer an alternative to colonoscopy that is less-invasive, is better-tolerated and has good diagnostic accuracy.

Fat to make you feel fuller
Scientists have designed a fatty formulation that can make you feel fuller for longer. When the fat remains stable in the acid environment of the stomach, it empties into the small intestine more slowly and increases satiety.

Autism tied to genes that influence brain cell connections
Researchers have identified a new gene variant that is highly common in autistic children. Gene, known as CDH10, is most active in key regions that support language, speech and interpreting social behavior.

A new drug for multiple sclerosis can dramatically reduce the chances of a relapse or a deterioration of the condition, according to a new study from researchers at Queen Mary, University of London.

Cardiac imaging exams have radiation risks
At the radiation dose levels used in cardiac imaging exams, such as cardiac CT or nuclear medicine scans, the risk of potentially harmful effects from ionizing radiation are low. However, since the exact level of risk is not known, people without symptoms of heart disease should think twice about seeking, or agreeing to, these types of cardiac studies.

Hazards of CT scans overstated in NEJM
A recent article by Drs.
