What restrictions may exist? At the Wellcome Centre for Human Neuroimaging, part of Queen Square Institute of Neurology at University College in London, where I started the study in 2011, there were increasing numbers of volunteers with tattoos. At the time, there simply was not enough data to determine the likelihood of tattoo-related side effects arising from MRI examinations." His former colleague in London, Martina Callaghan, completed the stu...

Regular aerobic exercise such as walking, cycling or climbing stairs may improve thinking skills not only in older people but in young people as well, according to a study published in the January 30, 2019, online issue of Neurology �, the medical journal of the American Academy of Neurology. The study also found that the positive effect of exercise on thinking skills may increase as people age. The specific set of thinking skills that improved with exercise is called executive function. Executive function is a person's ability to regulate their own behavior, pay attention, organize and achieve goals. "As people age, there can be a decline in thinking skills, however our study shows that getting regular exercise may help slow or even prevent such decline," said study author Yaakov Stern, PhD, of Columbia University in New York, and a member of the American Academy of Neurology. "We found that all participants who exercised not only showed improvement...

The benefits of vitamin D in promoting bone health are already well known. A new study out of Brazil suggests that vitamin D also may promote greater insulin sensitivity, thus lowering glucose levels and the risk of developing type 2 diabetes. Results are published online today in Menopause , the journal of The North American Menopause Society (NAMS). Other recent studies have shown a clear relationship between vitamin D and glycemic control, suggesting that vitamin D increases insulin sensitivity and improves pancreatic beta-cell function. In this cross-sectional study involving 680 Brazilian women aged 35 to 74 years, the goal was to evaluate the possible association between vitamin D deficiency and increased glycemia. Of the women interviewed, 24 (3.5%) reported using vitamin D supplements. Vitamin D supplementation was found to be negatively associated with high glucose levels. Habitual exposure to the sun also provided the same association, demonstrating that vitam...

The new study, published this week in the International Journal of Obesity , looked at 2,680 young adults who were not exercising regularly or dieting. Scientists found that after exercising for several weeks, formerly sedentary study participants were more likely to choose foods like lean meats, fruits and vegetables, while preferences for fried foods, sodas and other unhealthy options decreased. Participants were instructed ...

Exercise is often cited as the best preventive medicine, but how much is too much for the hearts of middle-aged athletes? Sports cardiologist Dr. Benjamin Levine led a study, now published in JAMA Cardiology , to find the answer. Dr. Levine is a Professor of Internal Medicine and Director of the Institute for Exercise and Environmental Medicine, a collaboration between UT Southwestern Medical Center and Texas Health Presbyterian Hospital Dallas. What is coronary calcium scanning and why is it important? Coronary calcium scanning is an imaging test that helps physicians classify patients without cardiac symptoms as low, intermediate, or high risk for heart attack. It represents how much calcium (and thus cholesterol deposits) has accumulated in the blood vessels that supply the heart. The scan can help physicians determine the need for medication, lifestyle modification, and other risk-reducing measures. "The question has never been whether exercise is good for yo...
