Swine Flu And The Influenza Virus In 1918
The influenza virus that wreaked worldwide havoc in 1918-1919 founded a viral dynasty that persists to this day, according to scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. In an article published online on June 29 by the New England Journal of Medicine, authors Anthony S. Fauci, M.D., Jeffery K. Taubenberger, M.D., Ph.D., and David M. Morens, M.D., argue that we have lived in an influenza pandemic era since 1918, and they describe how the novel 2009 H1N1 virus now circling the globe is yet another manifestation of this enduring viral family.

House Seeks To Pay For Reform With New Tax On Wealthy
House Democrats are expected to begin marking up a health reform bill this week that members of the Ways and Means committee said "would cost less than $1 trillion over 10 years, [and would be] paid for chiefly by a combination of spending reductions in the health care system and a surtax on wealthy taxpayers," CQ Politics reports. "The surtax would be levied beginning in 2011. ò€¦ [T]here would be three income brackets - $350,000, $500,000 and $1 million for couples filing jointly, and $280,000, $400,000 and $800,000 for individuals - with a different rate at each level: "One, two, three [percent] - something like that,"" the committee"s chairman, Charles Rangel, D-N.Y., said (Wayne, 7/13).

Nephrogenic Systemic Fibrosis And Gadolinium-Based Contrast Agents

Even at very high doses, gadolinium-based contrast agents alone are not sufficient to cause nephrogenic systemic fibrosis (NSF) in patients with kidney problems, according to a study performed at the Mayo Clinic Florida, Jacksonville, FL. NSF is a rare and serious syndrome that leads to fibrosis of the skin, joints and even internal organs. Some research indicates NSF is caused by gadolinium-based contrast agents that are commonly used today during MR procedures. The study examined the records of 61 patients. "Our patients had been given high doses - from two to ten times the usual MRI dose. These high doses were used because the patients were undergoing interventional procedures and the procedures were done before there were any reports linking gadolinium to NSF," said Mellena D. Bridges, MD, lead author of the study. "Fortunately, one of these patients, a 58-year-old diabetic man with end-stage kidney disease and significant blood vessel blockages, developed NSF. Gadolinium seems to be necessary to trigger NSF, but it doesn"t seem to be enough to cause the disease, even at very high doses," said Dr. Bridges. This study appears in the June issue of the American Journal of Roentgenology. Click here for abstract. Heather Curry American Roentgen Ray Society
