Are E-cigarettes Leading More Kids to Smoke?

Today, thanks to decades of educational efforts about the serious health consequences of inhaled tobacco, fewer young people than ever smoke cigarettes in the United States. So, it’s interesting that a growing of number of middle and high school kids are using e-cigarettes—electronic devices that vaporize flavored liquid that generally contains nicotine.
E-cigarettes come with their own health risks, including lung inflammation, asthma, and respiratory infections. But their supporters argue that “vaping,” as it’s often called, might provide an option that would help young people steer clear of traditional cigarettes and the attendant future risks of lung cancer, emphysema, heart disease, and other serious health conditions. Now, a new NIH-funded study finds that this is—pardon the pun—mostly a pipe dream.
Analyzing the self-reported smoking behaviors of thousands of schoolkids nationwide, researchers found no evidence that the availability of e-cigarettes has served to accelerate the decline in youth smoking. In fact, the researchers concluded the opposite: the popularity of e-cigarettes has led more kids—not fewer—to get hooked on nicotine, which meets all criteria for being an addictive substance.
Peanut Allergy: Early Exposure Is Key to Prevention

With peanut allergy on the rise in the United States, you’ve probably heard parents strategizing about ways to keep their kids from developing this potentially dangerous condition. But is it actually possible to prevent peanut allergy, and, if so, how do you go about doing it?
There’s an entirely new strategy emerging now! A group representing 26 professional organizations, advocacy groups, and federal agencies, including the National Institutes of Health (NIH), has just issued new clinical guidelines aimed at preventing peanut allergy [1]. The guidelines suggest that parents should introduce most babies to peanut-containing foods around the time they begin eating other solid foods, typically 4 to 6 months of age. While early introduction is especially important for kids at particular risk for developing allergies, it is also recommended that high-risk infants—those with a history of severe eczema and/or egg allergy—undergo a blood or skin-prick test before being given foods containing peanuts. The test results can help to determine how, or even if, peanuts should be introduced in the youngsters’ diets.
Morning Sickness Associated with Lower Miscarriage Risk

During the first trimester of pregnancy, many women experience what’s commonly known as “morning sickness.” As distressing as this nausea and vomiting can be, a team of NIH researchers has gathered some of the most convincing evidence to date that such symptoms may actually be a sign of something very positive: a lower risk of miscarriage.
In fact, when the researchers studied a group of women who had suffered one or two previous miscarriages, they found that the women who felt nauseous during their subsequent pregnancies were 50 to 75 percent less likely to miscarry than those without nausea. While it’s not yet exactly clear what’s going on, the findings lend support to the notion that morning sickness may arise from key biological factors that reflect an increased likelihood of a successful pregnancy.
Creative Minds: Helping More Kids Beat Anxiety Disorders

While earning her Ph.D. in clinical psychology, Dylan Gee often encountered children and adolescents battling phobias, panic attacks, and other anxiety disorders. Most overcame them with the help of psychotherapy. But not all of the kids did, and Gee spent many an hour brainstorming about how to help her tougher cases, often to find that nothing worked.
What Gee noticed was that so many of the interventions she pondered were based on studies in adults. Little was actually known about the dramatic changes that a child’s developing brain undergoes and their implications for coping under stress. Gee, an assistant professor at Yale University, New Haven, CT, decided to dedicate her research career to bridging the gap between basic neuroscience and clinical interventions to treat children and adolescents with persistent anxiety and stress-related disorders.
Resurgence of Measles, Pertussis Fueled by Vaccine Refusals

I was born in 1950 and was home-schooled until the 6th grade. Thus, I missed exposure to several childhood illnesses that affected most of my generation. I never gave it much thought until, as a medical resident in North Carolina in 1979, I came down with a potentially life-threatening febrile illness that required hospitalization. Only after four days of 105 degree fever did a rash appear, and the diagnosis was made: measles. That was the sickest I have ever been. It turned out that one of my daughter’s school friends had developed measles in a small outbreak of unvaccinated kids in Chapel Hill, and I had been exposed to her. I was born too early to have been vaccinated.
But for most people born in the United States after the 1960s, they have never had to experience the high fever and rash of the measles or the coughing fits of pertussis, commonly known as whooping cough. That’s because these extremely contagious and potentially life-threatening diseases have been controlled with the use of highly effective vaccines and strong vaccination programs. And yet, the number of Americans sickened with measles and pertussis each year has recently crept back up.
Now, an NIH-funded report confirms that many of the recent outbreaks of these vaccine-preventable diseases have been fueled by refusal by some parents to have their children vaccinated [1]. The findings, published recently in JAMA, come as an important reminder that successful eradication of infectious diseases depends not only on the availability of safe and effective vaccines, but also on effective communication about the vaccines and the diseases they prevent.
