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.

HANOI, Oct. 7 (Xinhua) -- Vietnam in cooperation with the United Nations Development Program (UNDP) and the Food and Agriculture Organization (FAO) organized a workshop here on Friday to finalize implementations in Phase 2 of the UN-Vietnam Joint Program to fight against Highly Pathogenic Avian Influenza (HPAI) during 2007-2011.The workshop is not only to review the achievements but also from that, Vietnam hopes to receive more supports from the UN agencies, said Bui Ba Bong, Vietnamese vice minister of Agriculture and Rural Development.According to the report, so far, Vietnam's project on prevention of HPAI has basically achieved the targets in terms of making plans, policies and strategies for the veterinary sector, assessing the impacts of destruction of poultry to the environment, controlling pandemic, and supporting vaccine inoculation, quarantine and control of the infected animals, said Bong.Vietnam showed great efforts in responding and preventing H5N1 pandemic during its occurrence in 2005-2006, evaluated UN agencies.In Phase 2, Vietnam achieved positive results in controlling and reducing the impacts of the pandemic, and promoting bio- security in livestock breeding. Therefore, UN pledged to continue assisting Vietnam in the future.The UN-Vietnam joint program to fight HPAI was designed to meet the needs of emergency assistance to control the avian and human influenza.Total fund of the program is 25 million U.S. dollars, of which over 18 million U.S. dollars was approved for Phase 2.

BEIJING, Jan. 8 (Xinhua) -- China canceled over one-third of all official ceremonies, seminars and forums last year in a bid to avoid extravagance or corruption in the use of public resources.Some 2,549 such activities proposed by governments or public institutions, or 37.7 percent of the total applications, which were deemed "ceremonial" and "unnecessary," were cut, saving 1.22 billion yuan (about 193.39 million U.S. dollars), said an official statement released Sunday.The statement was issued by the State Council's Office for Rectifying Malpractices, a ministry-level inter-agency supervisory body dedicated to eliminating administrative irregularities and abuse of power in government agencies, public institutions and major service sectors.Last year's inspections focused on activities co-funded by ministries and local governments, the statement said.The Chinese government agreed with the public that the soaring number of official celebrations, seminars and forums would cost plenty of money and manpower and exacerbate corrupt behaviors.In March, the State Council, or China's Cabinet, ordered 98 ministries and ministry-level government organs to make public their budgets and expenditures on official overseas visits, public vehicles and official receptions -- the "three public consumptions" that had triggered widespread public concern.Premier Wen Jiabao also repeatedly urged the country's government agencies to reduce administrative expenses, including cutting the number of meetings and documents printed.Official figures indicate that the country's crackdown on various forms of extravagant spending by officials saved the country 5.7 billion yuan in 2010.A blue book on China's conferences published in November estimated that the total output of the country's conference industry had reached nearly 1 trillion yuan. Companies made up half of this total, while a considerable portion came from the government and public institutions compared to other social organizations.

WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

SHANGHAI, Nov. 28 (Xinhua) -- The Shanghai municipal government Monday launched the microblog "Shanghai City" on China's popular Twitter-like microblogging service Weibo.com.The microblog, officially verified as originating from the Information Office of Shanghai Municipal Government (IOSMG), has accumulated more than 30,000 followers in the five hours since its launch.According to IOSMG, the content of the postings will be mainly about new policies and regulations, practical information related to activities in Shanghai, and interactions with Internet users over issues of public concern.Vegetable prices, the selection of affordable housing, and upcoming cultural activities in Shanghai are included in the first several postings.Some 600 government agencies and 300 government officials of various levels in Shanghai have verified Weibo accounts, the IOSMG said.The "Shanghai Metro," the official microblog of the city's metro operator with over 1.15 million followers, is considered one of most influential government microblogs in China.The latest statistics show that China now has more than 300 million registered microblog users.
