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.

BEIJING, May 24 (Xinhuanet) -- CT scan, a widely used heart-imaging test, is likely to result in the over treatment for patients with heart disease, according to a study published online by the Archives of Internal Medicine on Monday.CT, which produces a detailed image of the heart that reveals cholesterol buildups in the coronary arteries, is widely used in the hospital around the world."Testing might lead to more harm than good," said McEvoy, a doctor at Seoul National University Bundang Hospital in S. Korea.His team led the study, in which 2,000 healthy adults were divided into two groups. One thousand adults had CT scans and another half had standard tests, including routine checks of their blood pressure and cholesterol levels.After 18 months, the 215 people who had worrisome CT scans were advised to have additional tests and medical treatment, and some even advised to have surgery. But less than 10 percent in the group of standard test were reported to need medications.Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity.

MOSCOW, May 24 (Xinhua) -- Russia's Soyuz TMA-20 spacecraft with three crew members onboard has landed in Kazakhstan on Tuesday, said the Mission Control Center (MCC) outside Moscow.The spacecraft undocked from the International Space Station early Tuesday, carrying Russian cosmonaut Dmitry Kondratyev, European Space Agency (ESA) astronaut Paolo Nespoli and NASA astronaut Catherine Coleman back to Earth.According to the center, the Soyuz TMA-20 landed in the Kazakh steppe at 6:27 Moscow time (0227 GMT). Some 17 planes and helicopters and several rescue vehicles had conducted search works.Flight engineers Catherine "Cady" Coleman of the U.S. (L) and Italian Paolo Nespoli (R), and Russian cosmonaut and station commander Dmitry Kondratyev are seen after the Soyuz capsule landed, about 150 km (93 miles) southeast of the Kazakh town of Zhezkazgan May 24, 2011. A Russian Soyuz capsule delivered an international trio of astronauts back to Earth on Tuesday after six months on the International Space Station, parachuting through clear skies toward a safe landing on the Kazakh steppe.Deputy head of Federal Medical and Biological Agency Vyacheslav Rogozhkin said Italian astronaut Naspoli had some health problem after landing."Two crew members are fine, the third one has some problems with his vestibular system," Rogozhkin told a press conference after the landing.In December, the Soyuz TMA-20 was launched from the Kazakh Baikonur space center with three crew members.The next launch of manned spacecraft to the ISS was scheduled in early June.
