WASHINGTON, Nov. 14 (Xinhua) -- Nearly a fifth of all Americans 12 years or older have hearing loss so severe that it may make communication difficult, according to a new study led by Johns Hopkins University researchers and published Monday in the Archives of Internal Medicine.The findings, thought to be the first nationally representative estimate of hearing loss, suggest that many more people than previously thought are affected by this condition.Study leader Frank Lin, an assistant professor, and his colleagues used data from the National Health and Nutritional Examination Surveys (NHANES), a research program that has periodically gathered health data from thousands of Americans since 1971. The researchers analyzed data from all participants age 12 and over whose hearing was tested during NHANES examinations from 2001 to 2008. Unlike previous estimates, NHANES includes men and women of all races and ages, from cities scattered across the country, so it's thought to statistically mimic the population of the Untied States.Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumps to about 48 million, or 20.3 percent, for people who have hearing loss in at least one ear. These numbers far surpass previous estimates of 21 to 29 million.Hearing loss prevalence nearly doubled with every age decade, with women and blacks being significantly less likely to have hearing loss at any age. Lin and his colleagues aren't sure why these groups appear to be protected. However, he notes that the female hormone estrogen, as well as the melanin pigment in darker skin, could have a protective effect on the inner ear.

PARIS, Oct. 15 (Xinhua) -- Faced with new problems such as sovereign debt and downward risks, all countries should work together to enhance coordination on macroeconomic policies to guard economic growth and financial stability with respective effort, Chinese delegates said Saturday here at the G20 Financial Ministers Meeting.The global economy is challenged by new difficulties which require all countries to join hands in fighting all sorts of protectionism either in trade or in investment, according to a statement issued by the Chinese delegation led by Chinese Financial Minister Xie Xuren and Central Bank Governor Zhou Xiaochuan.China suggested that leading developed countries should ensure economic recovery and financial stability in short term, while in the medium term enhance fiscal solidarity, accelerate structural reform and refrain the negative impact of macroeconomic policies.Meanwhile, China also stressed that the emerging countries should make their own contribution to tackle the problems. "The emerging markets should promptly take flexible and effective macroeconomic measures in order to control slowdown and tackle with impacts from inflation and capital flows," the statement said.Emerging economies "should also quicken their pace on structural reform in a bid to realize stable and faster growth," the statement added.During the two-day meeting, G20 financial leaders gathering in Paris welcomed the progress the Europe made on the eurozone debt issue on Saturday, but meanwhile expected the euro area to rely more on itself with bigger bailout fund to avoid contagion.

BEIJING, Nov. 26 (Xinhua) -- Joint police patrols along the Mekong River will kick off in mid December to restore security after a deadly attack to Chinese ships in October.Chinese police will start patrols along the river with Laos, Myanmar and Thailand, said a statement from the Ministry of Public Security here Saturday.No exact date was given, but the first joint patrol will be carried out before Dec. 15, said the statement, issued after a ministerial meeting of four countries held in Beijing.Police from the four will work together to restore shipping and guarantee security along the river, the statement said.Shipping on the Mekong River has been suspended since two cargo ships were attacked on Oct. 5, resulting in the murder of 13 Chinese sailors.A headquarters for the initiative will be founded in China and there will be a coordination office in each of the other three countries. They will be linked by a round-the-clock communication mechanism, the statement said.China will assist Laos and Myanmar police in terms of training and equipment, the statement said.Police departments of the four countries will also set up a coordination team to work out more security measures along the Mekong River, it added.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."
