BEIJING, Nov. 30 (Xinhuanet) -- Heading football frequently may cause brain damage leading to subtle but serious declines in thinking and coordination skills, a new study suggested as quoted by media reports Wednesday.Researchers used an advanced MRI (Magnetic Resonance Imaging) technique to analyze changes in brain white matter of 32 adult amateur soccer players who head balls 436 times a year on average.The study found players who head football quite frequently -- with 1,000 or more a year -- showed abnormalities similar to traumatic brain injuries suffered in car accidents."This is the first study to look at the effects of heading on the brain using sophisticated diffusion tensor imaging," said Dr. Michael Lipton, a leading researcher and associate director of the Gruss Magnetic Resonance Research Center at the Albert Einstein College of Medicine in New York City."We found the real implication for players isn't from hitting headers once in a while, but repetitively, which can lead to degeneration of brain cells," he added.The researchers compared neurological images of study participants, whose average age was 31, and found those with the highest volume of headers had abnormalities in five areas of the brain, responsible for attention, memory, physical mobility and high-level visual functions.The findings come in the wake of mixed reports on the so-called "cognitive" consequences of frequently heading soccer balls at practice.Dr. Chris Koutures, a pediatrician and sports medicine specialist in Anaheim Hills, California, said the retrospective imaging study was fascinating, but needs more data to effectively determine safe header limits, especially for younger players.Dr. Lipton agreed neuropsychological damage from headers would be hard for a coach or physician to notice since cognitive problems develop gradually, and even players might not be aware of mild memory loss."We can't tell an individual today not to be heading a ball, but caution is a good thing," Lipton said. "We need more research for definitive answers and we have the advanced imaging tools to do it."

BEIJING, Oct. 24 (Xinhuanet) -- There is no evidence to prove that using a cell phone can increase the risks of brain cancer, suggested a lastest study by Danish researchers.To arrive at the result, the researchers examined the health records from 1990 to 2007 for 358,403 Danish cell phone plan subscribers.They found that among people using cell phones for as long as 13 years or more, the cancer risks were almost the same as for non-subscribers.The finding, published in the British Medical Journal last week, alleviated the fear among the world's 5 billion cell phone users.Five months ago, a statement from the World Health Organization's International Agency for Research on Cancer (IARC) sparked fear in cell phone users around the world because it said that cell phone use might cause brain cancer.However, the finding could not rule out the risk of brain cancer triggered by heavy use of cell phones, admitted Patrizia Frei of the Danish Cancer Society's Institute of Cancer Epidemiology, lead author of the study.Frei added, cited by CNN, "There are still some open questions, about greater amounts of use, and about the effects on children."The IARC did not give formal response to the study, but it offered some ways for cell phone consumers to reduce possible risks months ago.Texting and using hands-free sets for voice calls lower exposure to potentially harmful radiation, compared to device-to-ear voice calls, by at least 10-fold, IARC stated, reported by the New York Daily News.

WASHINGTON, Oct. 6 (Xinhua) -- The U.S. Food and Drug Administration (FDA) and the National Institutes of Health (NIH) announced Thursday a joint, large-scale, national study of tobacco users to monitor and assess the behavioral and health impacts of new government tobacco regulations.The initiative is the first large-scale NIH/FDA collaboration on tobacco regulatory research since the U.S. Congress granted FDA the authority to regulate tobacco products in an act in 2009. Scientists at NIH's National Institute on Drug Abuse and the FDA's Center for Tobacco Products will coordinate the effort."The launch of this study signals a major milestone in addressing one of the most significant public health burdens of the 21st century," said FDA Commissioner Margaret Hamburg in a statement. "The results will strengthen FDA's ability to fulfill our mission to make tobacco-related death and disease part of America's past and will further guide us in targeting the most effective actions to decrease the huge toll of tobacco use on our nation's health."Investigators will follow more than 40,000 users of tobacco- product and those at risk for tobacco use ages 12 and older. They will examine what makes people susceptible to tobacco use; evaluate use patterns and resulting health problems; study patterns of tobacco cessation and relapse in the era of tobacco regulation; evaluate the effects of regulatory changes on risk perceptions and other tobacco-related attitudes; and assess differences in attitudes, behaviors and key health outcomes in racial-ethnic, gender, and age subgroups."We are pleased to collaborate with the FDA on this study that may provide us with a better understanding of the impact of product regulation on tobacco prevention and cessation," said NIH Director Francis Collins.While smoking rates have dropped significantly since their peak in the 1960s, nearly 70 million Americans ages 12 and older were current users of tobacco products in 2010. As a result, death and disease caused by tobacco use is still a tremendous public health burden. Tobacco use is the leading preventable cause of disease, disability, and death in the United States. Cigarette smoking results in more than 443,000 premature deaths in the United States each year -- more than alcohol, illegal drug use, homicide, suicide, car accidents, and AIDS combined.
