Majority Of U.S. Citizens Have Inadequate Levels Of Vitamin E In Their Diet; It Is Almost Impossible To Take A Harmful Amount
Date: Apr-17-2013Despite concerns that have been expressed about possible health risks from high intake of vitamin E, a new review concludes that biological mechanisms exist to routinely eliminate excess levels of the vitamin, and they make it almost impossible to take a harmful amount. No level of vitamin E in the diet or from any normal use of supplements should be a concern, according to an expert from the Linus Pauling Institute at Oregon State University. The review was just published in the Journal of Lipid Research...
Inflammation Following Traumatic Brain Injury May Increase Risk For Dementia Later In Life
Date: Apr-17-2013Even a mild injury to the brain can have long lasting consequences, including increased risk of cognitive impairment later in life. While it is not yet known how brain injury increases risk for dementia, there are indications that chronic, long-lasting, inflammation in the brain may be important. A new paper by researchers at the University of Kentucky Sanders-Brown Center on Aging (SBCoA), appearing in the Journal of Neuroscience, offers the latest information concerning a "switch" that turns "on" and "off" inflammation in the brain after trauma...
Telescope Implant Improves Vision In Macular Degeneration
Date: Apr-17-2013Physicians at the Virginia Commonwealth University Medical Center have become the first in Virginia to successfully implant a telescope in a patient's eye to treat macular degeneration. The telescope implant is designed to correct end-stage age-related macular degeneration (AMD), the most advanced form of AMD and the leading cause of blindness in older Americans. Patients with end-stage AMD have a central blind spot. This vision loss makes it difficult or impossible to see faces, to read and to perform everyday activities such as watching television, preparing meals and self-care...
Patient's Photo On X-Ray Images Leads To Dramatic Drop In Wrong Patient Errors
Date: Apr-17-2013Adding a photo of a face to x-ray images can reduce "wrong-patient" errors five-fold, a new study finds. "X-rays can look alike, and if one patient's images are confused with another before the radiologist sees them, it can be difficult for the radiologist to determine there is a mismatch," said Dr. Srini Tridandapani, of Emory University and an author of the study. As part of the study, ten radiologists interpreted 20 pairs of radiographic images with and without photographs. Two to four mismatched pairs were included in each set of 20 pairs of images...
12 Principles For Effective Contraceptive Counseling
Date: Apr-17-2013New research by Professor James Jaccard, Ph.D., and Nicole Levitz, M.P.H., of the New York University Silver School of Social Work and its Center for Latino Adolescent and Family Health (CLAFH) has led them to suggest 12 evidence-based principles that can be used to improve contraceptive counseling of adolescents in U.S. health care clinics, doctor's offices, and health service organizations...
In Severe Depression ECT Can Restore Quality Of Life
Date: Apr-17-2013Patients whose severe depression goes into remission for six months following electroconvulsive therapy report a quality of life similar to that of healthy individuals, researchers say. "If we can get you into remission, you get this big, big improvement in quality of life at six months such that our patients' quality of life is as good as that of the overall general population," said Dr. W. Vaughn McCall, Chairman of the Department of Psychiatry and Health Behavior at the Medical College of Georgia at Georgia Regents University...
Mental Exercise May Prevent Cognitive Decline In Healthy Seniors
Date: Apr-17-2013Cognitive training exercises - or mental exercise - may help prevent cognitive decline in healthy older adults, while evidence for the benefits of pharmacologic substances and exercise is weak, outlines a review published in CMAJ (Canadian Medical Association Journal). Mild cognitive impairment (cognitive decline that is more than normal for someone of a specific age) affects 10%-25% of people over age 70. The annual rate of decline to dementia (which is cognitive decline in several areas along with some functional ability) is about 10%...
New Data On T Cells' Protective Role Suggests Need For New Approach To Dengue Vaccine Design
Date: Apr-17-2013As efforts to create a strong and effective vaccine for the dreaded dengue virus continue to hit snags, a new study from researchers at the La Jolla Institute for Allergy & Immunology offers surprising evidence that suggests the need for a revamped approach to dengue vaccine design. The finding runs counter to current scientific understanding of the key cells that need to be induced to develop a successful dengue vaccine. La Jolla Institute scientist Alessandro Sette, Dr.Biol.Sci...
Ferroelectricity In Body's Connective Tissues May Be Impaired By High Glucose Levels
Date: Apr-17-2013High sugar levels in the body come at a cost to health. New research suggests that more sugar in the body could damage the elastic proteins that help us breathe and pump blood. The findings could have health implications for diabetics, who have high blood-glucose levels. Researchers at the University of Washington and Boston University have discovered that a certain type of protein found in organs that repeatedly stretch and retract - such as the heart and lungs - is the source for a favorable electrical property that could help build and support healthy connective tissues...
Study Makes Significant Progress Toward Mouse Model Of Human Autism
Date: Apr-17-2013For the first time, researchers have linked autism in a mouse model of the disease with abnormalities in specific regions of the animals' chromosomes. The regions contain genes associated with aberrant brain development and activity. "These discoveries in mice may eventually pave the way towards understanding autism in human patients and devising new treatments," said co-senior author, Elliott H. Sherr, MD, PhD, a pediatric neurologist at UCSF Benioff Children's Hospital and professor of neurology at UC San Francisco (UCSF). The findings are reported in a study published in PLOS One...
