...Garvey notes that despite nearly 25,000 cases of positive, lab-confirmed H1N1 in people reported in the U.S. since last spring, the Iowa cat is the first pet to be documented with the virus. But before pet owners start suspecting Fido and Fluffy of being H1N1 hotbeds, Garvey stresses that so far, no cases of influenza of any kind in pets - including cases of bird flu - are known to have moved from animals into people. And even among the animals, the virus does not appear to spread easily, which may further suggest that pets are not ideal reservoirs...
Researchers on the study concluded that the actual number of cases hovered anywhere from 1.8 million to 5.7 million cases: far more than the 43,677 lab-confirmed cases that were identified nationwide through July, according to the paper. “Not every case, by a long shot, got reported...Once the number of cases grew, issues of capacity made testing and reporting even more significant,” wrote Marc Lipsitch, professor of epidemiology at the Harvard School of Public Health and a co-author of the study, in an e-mail...
...surgery, rather than the anesthetic.) The only research to associate surgical anesthesia in infancy to cognitive impairment later in life was Wilder's study earlier this year, but the literature on the whole in this area remains inconclusive. So far, the bulk of the evidence comes from studies in lab animals, rather than the human population. "The animal data is convincing," says Wilder. "But we need further studies to see if it's true in humans...
...cardiology at the University of Colorado, Denver, think the effect in humans won't be easy to show. At the ASA conference, Wise-Faberowski devoted her presentation to chiding researchers for worrying prematurely about "anesthesia-induced neurotoxicity," pointing out that it has been seen only in "cell cultures and lab animals." If anesthetics have always been neurotoxic, one slide in her presentation asked, "Why is it only an issue now?" She and others point out that non-human testing of anesthetic safety has an unreliable history. Ten years ago, for instance, lab researchers found evidence that isoflurane protected brain cells...
Halloween strikes fear into parents' hearts for reasons that have nothing to do with scary costumes. Hospitals have been offering to X-ray candy for decades, and this year a forensic lab in DuPage County, outside Chicago, will inspect suspicious sweets using technology that's usually reserved for homicide, sexual assault and burglary. Health officials are warning against letting kids scoop up candy with their germy hands, lest they spread H1N1 flu to other revelers. In Bobtown, Pa., spooked officials have banned trick-or-treating altogether. But is trick-or-treating really dangerous...
