Doctor pushes for compression-only CPR TUCSON (UPI) -- The head of Arizona's Sarver Heart Center says chest compression only, and not mouth-to-mouth resuscitation, should be used in emergency cardiac cases. Dr. Gordon Ewy has been criticized by many in the medical profession for his belief that mouth-to-mouth resuscitation detracts from the effectiveness of compression, The Arizona Republic reported Tuesday. "It's OK to be cantankerous and opinionated if you're right," he told the Republic. "And we're right." In the mid-1990s, Ewy pioneered the idea of continuous chest compression for cardiopulmonary resuscitation, CPR, though many doctors still believe CPR should include mouth-to-mouth resuscitation. In 2008, the American Heart Association said compression-only CPR was an option for people not trained in CPR or unsure of their skill. The association's advisory applied only to cases of adults in cardiac arrest, not children, and excluded drownings and drug overdoses. Ewy said he aims to convince more people of his method next month in Dallas during a meeting of the International Liaison Committee on Resuscitation, which represents the world's major resuscitation groups.

How tasks presented motivate differently CHAMPAIGN, Ill. (UPI) -- Some students told by a teacher to strive for excellence may be spurred to try harder, while others may become less motivated, U.S. researchers found. University of Illinois psychology Professor Dolores Albarracin, who conducted the research with William Hart of the University of Florida, suggests those who are "chronically uninterested in achievement" are not operating out of a desire to do badly. The researchers found that those with high achievement motivation did better on a task when they also were exposed to subconscious "priming" -- the flash of a word on a computer screen, for example, that appeared too briefly to be consciously noticed -- that related to winning, mastery or excellence. Those with low achievement motivation did worse under the same conditions, they said. In another study, the researchers found that those with high achievement motivation did worse on a word-search puzzle when they were told the exercise was fun and they had been exposed to achievement primes, such as the words "excel," "compete" or "dominate." Those not very motivated to achieve did better under the same conditions. "It's not that those with high achievement motivation always perform better," Albarracin said in a statement. "You can also get the low achievement motivation folks to perform better than the highs when you present a task as enjoyable and fun." The findings are published in the Journal of Personality and Social Psychology. Copyright 2010 by United Press International

Insulin mistakenly given at flu clinic WELLESLEY, Mass. (UPI) -- Insulin kept in a Wellesley, Mass., elementary school mistakenly was given to six staff members during a H1N1 flu clinic, authorities said. The insulin, rather than the flu vaccine, was administered Friday, said letters to parents from Wellesley Superintendent of Schools Bella Wong and Schofield School Principal David Wilkins. Several Schofield faculty members felt ill after receiving the insulin, WCVB-TV, Boston, reported Tuesday. No other details on the faculty members' condition were immediately available. The school employee who administered the insulin was placed on administrative leave pending the outcome of an investigation, Wong and Wilkins said in separate letters to parents. The insulin had been given to the school by parents of diabetic children and was being kept on hand for emergencies, WCVB-TV reported. Copyright 2010 by United Press International

Heart failure missing link discovered? CAMBRIDGE, England (UPI) -- British scientists say diseased hearts have DNA "marks" not found on healthy hearts. Lead author Dr. Roger Foo of the University of Cambridge in England said the marks -- known as DNA methylation -- are crucial in normal development allowing different cells to become different tissues despite having the same genes. The cells continue to occur throughout life in response to environmental changes. "DNA methylation leaves 'marks' on the genome, and there is already good evidence that these marks are strongly influenced by environment and diet," Foo said in a statement. "Linking all these things together suggests this may be the 'missing link' between environmental factors and heart failure." Foo and colleagues examined diseased tissue coming from male patients who had undergone heart transplants at Papworth Hospital in Cambridge and found DNA methylation not present in the healthy hearts of age-matched victims of road traffic accidents. The study, published in PLoS ONE, suggests the process could underlie development of different types of heart disease and may pinpoint those people at risk of heart disease, or in whom the disease will progress fastest. "This would radically alter how we manage patients with heart disease, allowing us to target treatments and tailor monitoring," Foo says. Copyright 2010 by United Press International
