‘Low glycemic’ diet helpful in diabetic youth
In children and adolescents with type 1, or insulin-dependent, diabetes, consumption of a low glycemic index diet may improve blood sugar control, according to results of a National Institutes of Health-sponsored study.
Glycemic index, or GI, refers to how rapidly a food causes blood sugar to rise. High-GI foods, like white bread and potatoes, tend to spur a quick surge in blood sugar, while low-GI foods, such as lentils, soybeans, yogurt and many high-fiber grains, create a more gradual increase in blood sugar.
Dr. Tonja R. Nansel of the National Institute of Child Health and Human Development and colleagues tested the effects of high GI and low GI meals on blood sugar levels using continuous blood sugar monitoring in 20 type 1 diabetics who were between the ages of 7 and 16 years.
Ritalin may help seniors stay steady on their feet
Taking methylphenidate—familiar as the drug Ritalin used to treat attention-deficit disorder—could help older people reduce their risk of falling by sharpening their mental function, Israeli researchers report.
After taking one dose of methylphenidate, seniors walked with a more even gait and did better on a standard screening test for fall risk, Dr. Jeffrey M. Hausdorff and colleagues found.
“Our study suggests that it may be possible to reduce the risk of falls in older adults by treating cognitive deficits associated with aging (and/or disease),” Hausdorff, of Tel-Aviv Sourasky Medical Center in Israel, told Reuters Health by email.
Fibromyalgia Affects Women More Often than Men
Are you exhausted? Do you have pain all over but can’t figure out what’s wrong? If so, you may be suffering from fibromyalgia, a chronic condition that causes exhaustion, sleep disturbances and diffuse pain in your muscles, tendons, and ligaments.
Fibromyalgia patients experience a range of symptoms of varying intensities that increase and decrease over time and often resemble other conditions. For years, because of their complex nature and a lack of research on the condition, many doctors misdiagnosed fibromyalgia symptoms or dismissed them as being in the patient’s head. Even today, it is estimated to take an average of five years for a fibromyalgia patient to get an accurate diagnosis.
There is no laboratory test available to diagnose fibromyalgia. Doctors must rely on patient histories, self-reported symptoms, a physical examination and an accurate manual tender point examination.
Higher wealth linked to lower stroke risk from age 50 to 64
Higher wealth is linked with a lower risk of stroke in Americans between the ages of 50 and 64, but does not predict strokes in those over age 65, researchers reported in Stroke: Journal of the American Heart Association.
“We confirmed that lower wealth, education and income are associated with increased stroke up to age 65, and wealth is the strongest predictor of stroke among the factors we looked at,” said Mauricio Avendano, Ph.D., co-author of the study. “After age 65, the association of education, income and wealth with stroke are very weak, and wealth did not clearly predict stroke.”
This is the first study assessing the age patterns of wealth, income and education disparities in stroke incidence in a national sample of older Americans. It’s also the first study reporting that wealth status predicts stroke incidence independently of income and education, said Avendano, a research fellow in public health at the Erasmus Medical Center in Rotterdam, The Netherlands.
Viruses may play a role in lung cancer development
Papers presented at the 1st European Lung Cancer Conference, jointly organized by the European Society for Medical Oncology (ESMO) and the International Association for the Study of Lung Cancer (IASLC) in Geneva, Switzerland highlight emerging evidence that common viruses may contribute to the development of lung cancer.
Experts agree that smoking is by far the most important factor that contributes to lung cancer development. But other factors can play a role in some cases.
In one report at the conference (Abstract No. 124PD; Friday 25th April, 09:50) Dr. Arash Rezazadeh and colleagues from the University of Louisville, Kentucky, USA, describe the results of a study on 23 lung cancer samples from patients in Kentucky.
