BEIJING, Nov. 22 (Xinhuanet) -- Underweight patients may have more possibilities of mortality within 30 days of general and vascular surgery compared with mildly obese patients, according to a research published online in Archives of Surgery Tuesday.Researchers at the U.S. National Surgical Quality Improvement Program conducted the research for the years 2005 and 2006, and assessed the contribution of BMI (Body Mass Index) to 189,533 postsurgeries morbidity and mortality by obesity classes.They found that compared with the middle BMI quintile group, patients with BMI value below 23.1, had greater chances for death. For the highest BMI quintile group, higher mortality rate was also observed.However, the researchers also found that obesity may as well be associated with increased mortality for some individual types of surgeries."These individual types of procedures include procedures with which the general surgeon should have definite experience: colorectal resection, colostomy formation, cholecystectomy, hernia repair, mastectomy, and wound debridement," said George J. Stukenborg, PhD, of the University of Virginia inCharlottesvilleand his colleagues.Based on a 30 –day morbidity and mortality risk calculation, the sample patients were categorized into BMI quintile ranges. BMI value of less than 23.1 was considered as lowest, values from 26.3 to 29.6 considered as the middle quintile, and above 35.2 considered as the highest.Factors such as lack of enough data on nonfatal complications and hospital resources, or examining mortality over the 30-day baseline, may cause limitations and inaccuracy to the research and more studies on a wider range of patients in terms of BMI are needed to further confirm the current conclusion, researchers said.

BEIJING, Nov. 22 (Xinhuanet) -- Women aged 40 to 49 are not recommended for routine mammography screening for breast cancer, said the new guidelines issued by the Canadian Task Force on Preventive Health Care in media reports Tuesday.The new guidelines are purposed to direct doctors on using mammography, MRI scans, clinical breast exams and breast self-exams. In principle, they pointed out, there is no need for women to take clinical breast exams and breast self examination if there are no signals for breast cancer.Below are the main points from the guidelines which need special attention from women with reasonable doubt on the matter:Women aged 40-49 who have lower risk for cancer should not take routine mammography because of the higher risk for overdiagnosis, overtreatment and false-positives;Women aged 50 to 69 years and aged 70 to 74 years should go for routine screening every two to three years;And there should be no routine clinical breast exams by doctors and no breast self-exams to screen for breast cancer.Dr. Marcello Tonelli, Chair of the Task Force and Associate Professor at the University of Alberta, remarked: "The main effect of screening is to produce patients with breast cancer from among healthy women who would have remained free of breast disease for the rest of their lives had they not undergone screening.""The best method we have to reduce the risk of breast cancer is to stop the screening program," he added, "This could reduce the risk by one-third in the screened age group, as the level of overdiagnosis in countries with organized screening programs is about 50 percent."

WELLINGTON, Oct. 26 (Xinhua) -- New Zealand's geothermal scientists will be collaborating with the world's leading geothermal researchers after the country joins an elite international group next month.New Zealand would be admitted to the International Partnership for Geothermal Technology (IPGT) in Melbourne, Australia, on Nov. 16, Science and Innovation Minister Wayne Mapp announced Wednesday."Geothermal energy is one of our most important renewable energy resources with huge potential for growth," said Mapp."This recognition of our geothermal research programs will allow our scientists to collaborate with an elite group of researchers in the United States, Australia, Switzerland and Iceland."Scientists from New Zealand research organizations were committed to finding new ways to harness the country's extensive geothermal fields, said Mapp."Innovation and clean energy is a big part of enabling New Zealand to grow the economy," said Mapp."This new international partnership will help keep us at the forefront of technology developments such as enhanced geothermal systems."Established in 2008, the IPGT seeks to develop advanced, cost- effective geothermal energy technologies through international research co-operation.New Zealand's geothermal electricity generation rose by 21 percent last year and accounted for 13 percent of total electricity generation, its highest recorded level.The government is aiming to expand geothermal energy with three large geothermal projects in the pipeline by 2020.The country's biggest geothermal project is to be Contact Energy's 250-megawatt Tauhara II geothermal project.The project, being developed northeast of the central North Island town of Taupo, is expected to produce enough electricity to meet the needs of around 270,000 homes when it becomes fully operational in 2015.

NEW DELHI, Jan. 9 (Xinhua) -- Chinese ambassador to India Zhang Yan Monday proposed that China and India make more efforts to develop economic ties.At a meeting on China-India relations attended by Indian National Security Advisor S. Menon, the ambassador said the Chinese side is fully aware of the necessity to narrow the trade gap between the two sides in order to ensure the sustainability of bilateral trade cooperation."China will take measures to increase the import of Indian products which have market demand in China. But our cooperation should not be limited in trade only," said the ambassador.He suggested that China and India should diversify their trade structure, expand the scope and items, and increase the technical content and added value to the products, while expanding into financial, service and investment sectors.The envoy said China and India should initiate policy dialogue and coordinate their economic development strategy in order to ensure steady growth of respective economy, encourage mutual investments, consider the free trade agreement or regional trade arrangement, and increase tourism cooperation.Zhang said that as an encouraging sign of economic ties, the bilateral trade volume is set to hit 70 billion U.S. dollars in 2011, an over 20 percent increase over the previous years, while China set up its first branch of the Industrial and Commercial Bank of China in Mumbai last year.

BEIJING, Jan. 8 (Xinhua) -- Only one in every three passengers secured train tickets on Saturday through a new online booking system or by phone, according to railway statistics released Sunday.A total of 2.112 million train tickets were sold online or by phone on Saturday, making up 36.3 percent of the total sales, the Ministry of Railways (MOR) said.Railway authorities have long been under pressure to increase capacity and improve ticketing services, as many find it extremely hard to secure a single ticket during major holidays such as the upcoming Spring Festival.The MOR set up an online ticketing system this year in a bid to ease passengers' frustrations in purchasing tickets.However, website glitches have added to the woes of travelers, especially migrant workers, who make up the biggest group in the Spring Festival travel rush.The rush, dubbed the world's largest seasonal migration, started Sunday and will continue for over 40 days.China's railways are expected to carry 235 million passengers over the next 40 days, up 6.1 percent year-on-year, the MOR said last week.The Spring Festival, or the Chinese Lunar New Year, falls on Jan. 23.
