WASHINGTON, April 11 (Xinhua) -- Taking a statin before having major elective surgery reduces potentially serious kidney complications, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology.Each year, more than 230 million major elective surgeries are performed around the world. Unfortunately, many patients who undergo major operations develop kidney injury soon after surgery, often due to decreased blood flow to the kidneys and/or the effects of inflammation.Animal studies suggest that the cholesterol-lowering drugs called statins protect the kidneys from such damage, but whether a similar benefit occurs in humans is uncertain. To investigate, Amber Molnar, University of Western Ontario, and colleagues conducted a population-based retrospective study of all older patients who underwent major elective surgery in the province of Ontario, Canada from 1995 to 2008. Surgeries included cardiac, thoracic, vascular, intra-abdominal, and retroperitoneal procedures.A total of 213,347 patients from 211 hospitals underwent major elective surgery, and 4,020 patients (1.9 percent) developed postoperative kidney injury within two weeks of surgery. A total of 1,173 patients (0.5 percent) required dialysis within two weeks of surgery, and 5,974 patients (2.8 percent) died within a month of surgery.Prior to surgery, 67,941 patients (32 percent) were taking a statin. Patients taking a statin were 20 percent less likely to develop kidney injury, need dialysis, and die compared to patients who were not taking a statin. Also, there was evidence of a dose-effect, with patients on higher potency statins having less kidney injury. In addition, statins were beneficial whether they were started greater than 90 days or less than 30 days prior to surgery."Our study suggests that statin use in older persons results in less kidney injury following major elective surgery and reduces the risk of premature death after surgery," said Molnar, adding that the results warrant further investigation with more rigorous studies, but such trials will be difficult to carry out.

LOS ANGELES, April 14 (Xinhua) -- Vegetarians experience a much lower risk of metabolic syndrome than non-vegetarians, U.S. researchers have found.Researchers at Loma Linda University in California based their findings on analysis of more than 700 adults randomly sampled from a long-term study of the lifestyle and health of almost 100,000 Seventh-day Adventist Christians across the United States and Canada.While 25 percent of vegetarians had metabolic syndrome, the number significantly rises to 37 percent for semi-vegetarians and 39 percent for non-vegetarians, according to the study published in the April issue of the journal Diabetes Care.The findings showed that the risk of developing metabolic syndrome is 36 percent lower among vegetarians than non- vegetarians.This means that vegetarians are less likely to develop heart disease, diabetes and stroke -- three major conditions that are closely linked with metabolic syndrome, the researchers say.The study also found that vegetarians, though slightly older than non-vegetarians, had lower triglycerides, glucose levels, blood pressure, waist circumference, and body mass index (BMI). Semi-vegetarians, meanwhile, also had a significantly lower BMI and waist circumference compared to those who ate meat more regularly.The findings will not be affected by other factors such as age, gender, race, physical activity, calories consumed, smoking, and alcohol intake, the researchers say."In view of the high rate of metabolic syndrome in the United States and its deleterious health effects, we wanted to examine lifestyle patterns that could be effective in the prevention and possible treatment of this disorder," says lead researcher Nico S. Rizzo, PhD."I was not sure if there would be a significant difference between vegetarians and non-vegetarians, and I was surprised by just how much the numbers contrast," he says. "It indicates that lifestyle factors such as diet can be important in the prevention of metabolic syndrome."

LOS ANGELES, May 25 (Xinhua) -- NASA project managers bade farewell to the Mars rover Spirit on Wednesday after sending a final set of commands to the stranded vehicle.This marks the completion of one of the most successful missions of interplanetary exploration ever launched, NASA's Jet Propulsion Laboratory (JPL) said."Last night, just after midnight, the last recovery command was sent to Spirit," said John Callas, the Mars Exploration Rover Project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Los Angeles."It would be an understatement to say this was a significant moment. Since the last communication from Spirit on March 22, 2010, as she entered her fourth Martian winter, nothing has been heard from her."NASA has tried in vain to regain communication with Spirit since it got stuck in sand about two years ago. The rover last communicated on March 22, 2010, as Martian winter approached and the rover's solar-energy supply declined.NASA checked frequently in recent months for possible reawakening of Spirit as solar energy available to the rover increased during Martian spring, but to no avail.A series of additional re-contact attempts ended on Wednesday, designed for various possible combinations of recoverable conditions, according to JPL."Our job was to wear these rovers out exploring, to leave no unutilized capability on the surface of Mars, and for Spirit, we have done that," said Callas.

ABU DHABI, Feb. 10 (Xinhua) -- China is willing to deepen friendship, broaden cooperation, and enhance coordination with the United Arab Emirates (UAE) in international and regional affairs, visiting Chinese Foreign Minister Yang Jiechi said Thursday.During a meeting with Abu Dhabi Crown Prince Sheikh Mohammed bin Zayed Al Nahyan, Yang said China and the UAE have witnessed in recent years rapid development in their bilateral ties, with closer high-level contacts, increasingly strengthened mutual political trust, fruitful cooperation in such areas as trade and economy, and broadened cultural exchanges.China has praised the UAE's support in Xinjiang-related and human rights issues, he added.For his part, Sheikh Mohammed said the UAE-China relations are currently at an important period of in-depth development and faced with good opportunities.The UAE attaches great importance to its relations with China and hopes to cement the traditional friendship between the two countries and develop pragmatic cooperation in various fields, he added.Sheikh Mohammed said the UAE expects that China will continue to play a positive role in international and regional affairs.Earlier in the day, Yang also met with his UAE counterpart Sheikh Abdullah bin Zayed Al Nahyan. Both sides reached broad consensus after exchanging views on bilateral ties and regional issues of common concern.The Chinese foreign minister arrived in the UAE capital of Abu Dhabi late Wednesday for an official visit to the Gulf nation.

LOS ANGELES, March 18 (Xinhua) -- The moon will move closer to Earth than it has been in more than 18 years Saturday night, space. com reported on Friday.On Saturday afternoon at 3 p.m. Eastern Daylight Time (1900 MGT) , the "supermoon", as dubbed by some observers, will arrive at its closest point to the Earth in 2011: a distance of 221,565 miles ( 356,575 kilometers) away, and only 50 minutes earlier, the moon will officially be full, the report said.At its peak, the supermoon may appear 14 percent larger and 30 percent brighter than lesser full moons (when the moon is at its farthest from Earth), weather permitting, said the report.Yet to the casual observer, it may be hard to tell the difference, according to the report.Scientists say it is a fluke of orbital mechanics that brings the moon closer to Earth.The supermoon will not cause natural disasters, such as the Japan earthquake, NASA scientists say.In December 2008, there was a near-supermoon when the moon turned full four hours away from its perigee - the point in its orbit that is closest to Earth. But this month, the full moon and perigee are just under one hour apart, promising spectacular views, depending on local conditions, the report said.
