Yale Researchers Find New Trigger For Seasonal Allergies
In research that could open new avenues of treatment for seasonal allergies, a team of Yale University scientists has discovered how a poorly understood component of the human immune system triggers - and sometimes worsens - allergic reactions. The research appears in the May 24 Advance Online Publication of Nature Immunology.

Teens Need To Hear About 'More Than Abstinence,' Philadelphia Inquirer Editorial Says
Although it is "important for other young people to hear" Bristol Palin"s message "about how hard it is to be a teenage mother," her "lesson falls short by suggesting that any teen can successfully avoid premarital sex," a Philadelphia Inquirer editorial says. Palin, who gave birth in December 2008 after an unintended pregnancy and is the daughter of Alaska Gov. Sarah Palin (R), has "changed her tune" since she said in a February interview that teen abstinence is ""not realistic at all,"" the editorial states. It adds that Bristol Palin -- now an "abstinence ambassador" for the Candie"s Foundation -- recently said that abstinence is "realistic" and that it is the "harder choice, but it"s the safer choice."The editorial continues that Palin is correct that "[a]bstinence is the only foolproof way to avoid pregnancy" and sexually transmitted infections. However, "any viable lesson about avoiding teen pregnancy should include methods besides avoiding sex, including the use of condoms," the editorial says. Recent studies have shown that abstinence-only sex education programs have had "no measurable impact on delaying teens from having sex for the first time," according to the editorial, which adds that teen pregnancy rates rose 5% between 2005 and 2007 after years of declines. Additionally, three out of 10 U.S. girls will get pregnant by age 20, a figure that increases to more than 50% for Hispanics and blacks. The editorial concludes that teens "need frank talk about premarital sex that includes all of the viable options to avoid pregnancy" (Philadelphia Inquirer, 5/15).

Oral Bacteria May Contribute To The Development Of Obesity

The world-wide explosion of overweight people has been called an epidemic. The inflammatory nature of obesity is widely recognized. Could it really be an epidemic involving an infectious agent? In this climate of concern over the increasing prevalence of overweight conditions in our society, investigators have focused on the possible role of oral bacteria as a potential direct contributor to obesity. To investigate this possibility, the study"s researchers J.M. Goodson, D. Groppo, S. Halem and E. Carpino measured salivary bacterial populations of overweight women. Saliva was collected from 313 women with a body mass index between 27 and 32, and bacterial populations were measured by DNA probe analysis. Levels in this group were compared with data from a population of 232 healthy individuals from periodontal disease studies. The median percentage difference of seven of the 40 bacterial species measured was greater than 2 percent in the saliva of overweight women. Classification tree analysis of salivary microbiological composition revealed that 98.4 percent of the overweight women could be identified by the presence of a single bacterial species (Selenomonas noxia) at levels greater than 1.05 percent of the total salivary bacteria. Analysis of these data suggests that the composition of salivary bacteria changes in overweight women. It seems likely that these bacterial species could serve as biological indicators of a developing overweight condition. Of even greater interest, and the subject of future research, is the possibility that oral bacteria may participate in the pathology that leads to obesity. The complete research study is published in the June issue of the International and American Associations for Dental Research"s Journal of Dental Research.
