...until then, neither Nolan nor officials at the Centers for Disease Control and Prevention (CDC) are ready to ditch the second dose. For one thing, they note, the level of antibodies does not always translate to actual protection against the flu. "Lab studies are a proxy and work well," says Dr. Anthony Fiore, at the CDC's National Center for Infectious Diseases, who wrote an editorial accompanying the study in the Journal of the American Medical Association. "But until you can show that a single dose is as effective as two, it's probably too soon to pull away from...
Experts note that the CDC database - the Autism and Developmental Disabilities Monitoring Network (ADDM) - is the closest thing to an ideal measure of autism's prevalence. The data are culled from assessments made by health or developmental professionals, including pediatricians, psychologists and language and speech pathologists. In previous evaluations, autism estimates were based on less reliable parental reporting of symptoms or diagnoses...
Another strength of the ADDM network is that it allows researchers to track autism rates over time. For the current study, Catherine Rice, a behavioral scientist at the CDC's National Center of Birth Defects and Developmental Disabilities, compared data from 10 sites in 2002 with the latest figures from 2006 - using a consistent definition of ASD - to determine that the prevalence of ASD had increased...
...true increase in ASD risk and how much is due simply to improved awareness and diagnosis of the disorders. Increased access to special education classes and other therapies may also be inflating the numbers, as educators and parents enroll more children in hopes of optimizing their learning environment. Indeed, CDC researchers found that among sites where they had access to both health and education records, the prevalence of ASD was higher on average than in sites where only health information was available...
...latest statistics underscore the looming public health problem that autism has become, and highlight the urgent need for research on causes and treatments, as well as better support services for families caring for autistic children. The CDC considers ASDs a significant public health concern, says Rice, and researchers across the country continue to discover new genes associated with the condition. But for advocates of families affected by autism, the efforts are still not enough. "We are really seeing exciting things happening, but the pace is too slow, it just doesn't measure up to the size of the crisis," says...
