Use Of Gestures Aids Language Development In Children With Brain Lesions
Date: Feb-22-2013Children with brain lesions suffered before or around the time of birth are able to use gestures - an important aspect of the language learning process - to convey simple sentences, a Georgia State University researcher has found. Seyda Ozçaliskan, assistant professor of psychology, and fellow researchers at the University of Chicago, looked at children who suffered lesions to one side of the brain to see whether they used gestures similar to typically developing children...
Following The Death Of A Child, Being Stoic For The Spouse's Sake Comes At A High Cost
Date: Feb-22-2013Among life's many tragedies, the death of a child is one that is perhaps the greatest for parents. No matter what the age of the child or the cause of death, the irrefutable fact of the loss is one that shatters the normal cycle of life, leaving parents traumatized and often incapacitated by grief. Research on coping with bereavement has focused primarily on the individual, despite the fact that family and married relationships are all profoundly disrupted by the loss...
Data Analysis Of Seniors Quitting Reveals Less Heart Attacks And Strokes
Date: Feb-22-2013Professor Hermann Brenner and colleagues analyzed the data of 8.807 individuals aged between 50 and 74 years using data of Saarland citizens. "We were able to show that the risk of smokers for cardiovascular diseases is more than twice that of non-smokers. However, former smokers are affected at almost the same low rate as people of the same age who never smoked," says Brenner. "Moreover, smokers are affected at a significantly younger age than individuals who have never smoked or have stopped smoking...
New Study Sets The Record Straight On Medicare's Overhead Costs
Date: Feb-22-2013The traditional Medicare program allocates only 1 percent of total spending to overhead compared with 6 percent when the privatized portion of Medicare, known as Medicare Advantage, is included, according to a study in the June 2013 issue of the Journal of Health Politics, Policy and Law. The 1 percent figure includes all types of non-medical spending by the Centers for Medicare and Medicaid Services plus other federal agencies, such as the IRS, that support the Medicare program, and is based on data contained in the latest report of the Medicare trustees...
Increased Risk Of Domestic Violence, Resulting Mental Health Problems For Victims With Disabilities
Date: Feb-22-2013People with disabilities are at a greater risk of being the victims of violence and of suffering mental ill health when victimized, according to research published February 20 in the open access journal PLOS ONE by Hind Khalifeh and colleagues from University College London and King's College London. A recent World Report on Disability highlighted violence as a leading cause of morbidity among disabled people. The research is the first to assess the extent to which people with disabilities experience different kinds of violence and the associated health and economic costs...
Slow-Firing Neurons, Human Cognition And How A Breakdown Of The System Contributes To Schizophrenia And Alzheimer's Disease
Date: Feb-22-2013Good mental health and clear thinking depend upon our ability to store and manipulate thoughts on a sort of "mental sketch pad." In a new study, Yale School of Medicine researchers describe the molecular basis of this ability - the hallmark of human cognition - and describe how a breakdown of the system contributes to diseases such as schizophrenia and Alzheimer's disease...
Chronic Acid Reflux Controlled By Device That Encircles The Valve At The Junction Of The Esophagus And Stomach
Date: Feb-22-2013A bracelet-like device with magnetic beads can control the chronic digestive disorder gastroesophageal reflux disease, according to a study published online today in the New England Journal of Medicine. The device encircles the valve at the junction of the esophagus and stomach and helps it stay closed when a person is not eating or drinking. It eased symptoms in 92 of 100 patients with chronic acid reflux and allowed 87 percent of patients to stop using acid-suppressing drugs, third-year results from the five-year study showed...
Development Of Human Heart Tissue Slower Than In Other Mammals
Date: Feb-22-2013The walls of the human heart are a disorganised jumble of tissue until relatively late in pregnancy despite having the shape of a fully functioning heart, according to a pioneering study. A University of Leeds-led team developing the first comprehensive model of human heart development using observations of living foetal hearts found surprising differences from existing animal models. Although they saw four clearly defined chambers in the foetal heart from the eighth week of pregnancy, they did not find organised muscle tissue until the 20th week, much later than expected...
Bioengineered Ears Using 3-D Printing And Injectable Molds, Look And Act Like The Real Thing
Date: Feb-22-2013Cornell bioengineers and physicians have created an artificial ear - using 3-D printing and injectable molds - that looks and acts like a natural ear, giving new hope to thousands of children born with a congenital deformity called microtia. In a study published online in PLOS ONE, Cornell biomedical engineers and Weill Cornell Medical College physicians described how 3-D printing and injectable gels made of living cells can fashion ears that are practically identical to a human ear...
Brain Cells Talk Too Much In Fragile X
Date: Feb-22-2013The most common inherited form of mental retardation and autism, fragile X syndrome, turns some brain cells into chatterboxes, scientists at Washington University School of Medicine in St. Louis report. The extra talk may make it harder for brain cells to identify and attend to important signals, potentially establishing an intriguing parallel at the cellular level to the attention problems seen in autism. According to the researchers, understanding the effects of this altered signaling will be important to developing successful treatments for fragile X and autism...
