New Detectors For Nuclear, Radiological Material In Cargo Should Not Be Acquired Until Testing Deficiencies Fixed, Cost-Benefit Analysis Completed
A thorough cost-benefit analysis that includes an assessment of meaningful alternatives is needed to reveal the potential security advantages of deploying new detector systems to screen cargo for nuclear and radiological materials at U.S. ports and border crossings. It is likely that the costs will exceed the savings gained from improved efficiency of the screening systems, says a new report from the National Research Council. There are shortcomings in the U.S. Department of Homeland Security"s testing of these new detector systems, therefore the DHS secretary cannot conclude whether they will consistently outperform the current ones. DHS should not proceed with further procurement of these new detector systems until the issues are addressed and the systems have been shown to be a favored option in the cost-benefit analysis.

The Gout & Uric Acid Education Society (GUAES) Announces New Survey Results Highlighting Major Gaps In Public Awareness Of Gout
The Gout & Uric Acid Education Society announced that new survey results reveal alarming gaps in the public"s awareness of gout, a painful and potentially debilitating form of arthritis that affects three to five million Americans. In a survey of more than 2,000 Americans, 65% of adults admitted to being "not at all knowledgeable" about gout and just over 70% did not know that gout is a form of arthritis. In fact, gout is the most common form of inflammatory arthritis among adults.

MiCardia® Announces First U.S. Implant
MiCardia® (MiCardia Corporation, Irvine, California) announced the completion of the first U.S. implant of its Dynaplasty® mitral valve repair technology. The surgery was performed last week at Beaumont Hospital, Royal Oak, Michigan. Francis L. Shannon, M.D., who is a partner in SEMCVS and Director of CV Surgical Research and Quality Outcomes at Beaumont, commented, "The MiCardia® device implanted easily and conformed well to the patient"s mitral annulus. The complete D-shaped ring was used to reinforce a complex repair of a flail leaflet segment using minimally invasive techniques. We are excited to be participating in the DYANA Study and believe Dynaplasty® technology will address a major weakness of current devices, namely their inability to deal with changes in valve shape and function after the initial repair procedure."

The End Of The Line For Existing Stem Cell Research?

Time is short for scientists to respond to the call for comments on the National Institutes of Health (NIH) proposed guidelines for the use of human embryonic stem (ES) cell lines and their eligibility for federal funds. On May 26, the window to provide feedback will close, and the drafted rules leave the possibility that funding for almost all existing cell lines will disappear. In a Forum article published online on May 14 by Cell Press in the journal Cell Stem Cell, Patrick Taylor, deputy general counsel at Children"s Hospital Boston, explains some of the legal implications of the NIH"s new funding rules, should they be adopted as written. Since the rules are retroactive, he explains, ongoing research is threatened. "Research with almost all existing cell lines will not be fundable, leaving almost no federal funds for research using cells created ethically since 2001. This will mean a loss of much of the research benefit of the last eight years, even though that research was independently reviewed and determined to be ethical under federal standards," says Taylor. "It is vitally important that scientists are aware of this problem and that the situation is resolved as quickly as possible." Ronald McKay, director of the NIH Stem Cell Unit, agrees and points out that, as proposed, the current draft guidelines may not even allow for continued research on the 21 ES cell lines approved by President Bush in 2001. "It is important to recognize that continued access to the ES cells themselves is important for medical research," says McKay. "It is common to use the economic metaphor of the "gold standard" when discussing the value of human ES cells. But unlike gold, stem cells will not retain value if they are locked in a bank and we cannot analyze their secrets. Continued access to these cells will ensure no delay in understanding the links between human genetics and disease," he adds. The slow pace of commenting is symptomatic of a broader tendency within the scientific community. "Despite federal encouragement and the ease of posting a comment, scientists do not seem to be participating unless the proposals directly impact their research," outlines science writer Amy Maxman in an Analysis piece to be published by Cell Press in the journal Cell on the same day. The article explains how scientists can offer their views as part of the consultation on items listed at the Federal Register, such as by providing comments on the draft human ES cell guidelines currently under consideration, to ensure that federal agencies receive a balanced perspective of public opinion. Researchers from all scientific disciplines and interested members of the general public can comment on the proposed guidelines at http://nihoerextra.nih.gov/stem_cells/add.htm until 11 p.m. EST on May 26. The reseacher is Patrick Taylor, of Children"s Hospital Boston, Harvard Medical School, in Boston, MA. Cathleen Genova Cell Press
