Automated test for West Nile screening of donors approved

first_img Though the number of transfusion-transmitted WNV cases has decreased dramatically since testing began, a report in the Feb 2 Morbidity and Mortality Weekly Report detailed the cases of two South Dakota patients whose disease probably came from a single infected donor whose screening tests were negative at the time of donation. The CDC said the cases underscore the importance of clinical recognition, effective WNV blood screening strategies, and investigation coordination. The Procleix TIGRIS system, developed by Gen-Probe, Inc., San Diego, and marketed by Chiron Corp., Emeryville, Calif., was approved by the FDA on Mar 2 and uses Gen-Probe’s Procleix WNV assay, which is already being used in the company’s semiautomated screening system, Gen-Probe said in a March 2 press release. Mar 9, 2007 (CIDRAP News) – The first fully automated test to screen donors of blood, tissue, and organs for West Nile virus (WNV) was recently approved by the US Food and Drug Administration (FDA). The automated system allows blood centers to process 1,000 individual blood samples in about 14 hours, Gen-Probe said. Blood testing sites typically use pooled samples to screen for WNV, then switch to individual donor testing once predetermined WNV prevalence triggers are met, the company said. “This is the latest step forward in what has been a very successful industry-government effort to keep blood safe from the emerging threat of West Nile virus,” he said in the press release. Mar 2 Gen-Probe press release WNV was first detected in the United States in 1999 and has since become endemic. For the 2006 season, 4,256 cases of West Nile virus have so far been reported to the Centers for Disease Control and Prevention (CDC); 1,449 cases involved West Nile encephalitis or meningitis, and 165 were fatal. People usually catch WNV from the bite of a mosquito that has picked up the pathogen from an infected bird or animal. Most people experience no symptoms or only mild illness, but the virus can cause serious infections of the brain and nervous system.center_img Mar 2 FDA press release Development of a WNV blood test began in 2002 when researchers discovered that the virus could be transmitted in blood, and nationwide screening for the virus began in 2003. Testing detected about 1,400 potentially infectious blood donations from 2003 to 2005, according to the CDC.

West Ham close to survival after vital win over Watford

first_imgDavid Moyes urged West Ham to finish the job after they effectively sealed their Premier League survival with a first half goal-blitz in Friday’s 3-1 win over relegation rivals Watford. Moyes’ side ran riot before the break at the London Stadium thanks to goals from Michail Antonio, Tomas Soucek and Declan Rice. Troy Deeney got one back for Watford after the interval, but the visitors couldn’t muster an unlikely escape act. West Ham climbed to 15th place and sit six points clear of the relegation zone with just two games left. Holding a vastly superior goal difference to third bottom Bournemouth and second bottom Aston Villa, the Hammers should be safe from the drop. After their second successive win, West Ham need one more point to guarantee their survival. If other results make them do it themselves, Moyes is confident his players will be up to the task against Manchester United and Aston Villa. “We are in a good position. Teams still have that chance and we have to do the job,” Moyes said. “Even scoring the goals has helped, I wanted us to keep our goal difference as good as it could be. “We have 37 points with a couple of games to go. If we get 40 points we’ll have done it off our own back.” Fourth bottom Watford are just three points above the relegation zone and face a nerve-wracking finish to the season.

I’d expect better from our players,” Pearson said. “I’ll look at it again and players will get honest feedback. They will go home tonight and think ‘wow we’ve let that one drift past us’. “It wasn’t good enough. We know that we have the toughest run-in but we have to cope with it.” – In-form Antonio – Antonio had scored four times in West Ham’s rout of Norwich last weekend and the forward was too hot for Watford to handle as well. West Ham took the lead in the sixth minute when Pablo Fornals played in Antonio and he fired past Ben Foster for his seventh goal since the coronavirus hiatus. Less than five minutes later, Watford’s task was made harder when Soucek headed home from Jarrod Bowen’s cross. England midfielder Rice produced a superb 30-yard strike to put West Ham three up in the 36th minute. Watford striker Deeney reduced the deficit in the 49th minute, tapping in after Abdoulaye Doucoure’s shot rebounded off a post. But Deeney was forced off with an injury and Watford couldn’t fight back without their captain.last_img read more
