In Health Care Debate, Small Businesses Are Key
"As they work to overhaul the nation"s healthcare system, President Obama and his congressional allies have pledged to help small-business owners such as Rhonda Ealy and Kelli Glasser," The Los Angeles Times reports. "Both businesswomen desperately want help. But they have strongly divergent views about what Washington should do, reflecting a broader debate about how to relieve the burden on the nation"s roughly 6 million small businesses." Ealy owns a coffee roasting company in Bend, Ore. with 13 employees, she says she "loves a Democratic proposal to create a government-run insurance plan, which she hopes will allow her to get her employees better coverage for less." Glasser, who "makes museum and trade-show exhibits" and has 87 employees, "hates a separate provision in the legislation that would place a new requirement on many businesses to cover their employees."

Government-Run Screening Programs Might Lead To Overtreatment Of Breast Cancer, Danish Study Says
One in three breast cancer patients identified in certain nations" public screening programs might have undergone unnecessary treatment, according to a study published Friday in BMJ, the AP/Google.com reports. For the study, Karsten Jorgensen and Peter Gotzsche of Copenhagen"s Nordic Cochrane Centre examined breast cancer trends at least seven years before and after the launch of government-run screening programs in parts of Australia, Canada, Great Britain, Norway and Sweden. The programs usually test women ages 50 to 69.According to the AP/Google.com, effective screening programs should detect more cases and result in a decline in advanced cancer cases detected in older women, whose cancers would have been caught in earlier screenings. However, the study found that the national screening systems simply detected thousands more cases than previously identified.Experts say that overtreatment of cancer occurs wherever there are widespread screening programs, including in the U.S. Some cancers develop too slowly to ever cause symptoms or death, the AP/Google.com reports. However, it is impossible to determine which cancers will be deadly, so all detected cases are treated. Jorgensen said that there is "significant harm in making women cancer patients without good reason" and that the "information needs to get to women so they can make an informed choice."Gilbert Welch of the VA Outcomes Group and the Dartmouth Institute for Health Policy and Research wrote in an accompanying editorial that although mammography "undoubtedly helps some women," it "hurts others." Welch wrote that it is "one of medicine"s "close calls," ... where different people in the same situation might reasonably make different choices."Britain"s National Health Service recently stopped distributing breast cancer screening pamphlets in response to criticism that they included too little information on cancer overtreatment. Laura Bell of Cancer Research UK said that although the organization still urges women to be screened, it is important that they be made aware of potential benefits and harms (Cheng, AP/Google.com, 7/9).

Luminex Receives FDA Clearance For An Update To The XTAG(R) Respiratory Viral Panel Package Insert
Luminex Corporation (NASDAQ: LMNX), the worldwide leader in multiplexed solutions, today announced that the U.S. Food and Drug Administration (FDA) has cleared labeling updates for the company"s xTAG® Respiratory Viral Panel (RVP) to include data about the performance of the test in humans infected with the pandemic strain of influenza A, 2009 influenza A/H1N1, which is sometimes referred to as "swine flu." The test"s labeling has been updated to include information from two new studies that demonstrate that xTAG RVP can be an effective aid in the detection of 2009 Influenza A/HIN1, but cannot identify the hemagglutinin gene of the 2009 Influenza A/H1N1 in clinical specimens.

Smokeless Tobacco Safer Than Smoking

Smokeless tobacco products, as used in Europe and North America, do not appear to increase cancer risk. A large meta-analysis, published in the open access journal BMC Medicine, has shown that snuff as used in Scandinavia has no discernible effect on the risk of various cancers. Products used in the past in the USA may have increased the risk, but any effect that exists now seems likely to be quite small. Peter Lee and Jan Hamling, from P.N. Lee Statistics and Computing Ltd, carried out the analysis of 89 studies from the United States and Scandinavia. They found that, after adjustment for concurrent smoking, any effect of current US products or Scandinavian snuff seems very limited. According to Lee, "It is clear that any effect of smokeless tobacco on risk of cancer, if it exists at all, is quantitatively very much smaller than the known effects of smoking". In 2005 in US men aged 35 or over, there were a total of 142,205 deaths from seven cancers considered to be caused by smoking. If these people had never smoked, Lee and Hamling estimated that the numbers would have reduced by 104,737, with the reduction in lung cancer deaths, 79,195, being the major contributor. If smokeless tobacco was introduced to a similar population of never smokers, this meta-analysis shows that any increase in risk would be negligible compared to the lives saved by reducing cigarette use. Lee said, "Our paper shows very clearly that, in marked contrast to smoking, smokeless tobacco use carries little or no risk of cancer. Concerns about possible effects of smokeless tobacco on oral cancer are answered by our analyses showing a lack of relationship based on the combined evidence from those 14 studies published since 1990 which allow adequate control for effects of smoking."
