If you think your hands are germ-free after you use hand sanitizer…think again. A study in the journal Science Translational Medicine finds that a few kinds of germs are developing resistance to alcohol-based hand sanitizers…and people who don’t rub their hands with them long enough are helping them along. Researchers say using sanitizer is still a good idea, but you can’t expect sanitizers to make up for sloppy habits.

A new study advises surgeons to stay away from children’s tonsils. The study in the journal JAMA Otolaryngology Head and Neck Surgery finds that removing tonsils and adenoids in childhood triples the odds of respiratory infections and allergic diseases later on. Tonsil removal is one of the most common pediatric surgeries performed worldwide, with more than 500,000 done each year on children in the U.S. alone.

A person’s biological age is often different from their chronological age…and the number of pregnancies a woman’s had can be one reason. A study in the journal Scientific Reports shows that during pregnancy, the cells in a woman’s body appear younger. But after pregnancy, that all changes. Later on, each pregnancy a woman has in her life ages her cells by as much as two years.

And finally…your sparkling water may be calorie-free…but it may still sabotage your diet. A study in the journal Obesity Research and Clinical Practice shows that carbonated water such as La Croix dramatically raises blood levels of ghrelin…the hormone that tells your brain that you’re hungry. Apparently, carbon dioxide bubbles are the culprit. Mice who drank carbonated water for a year ate significantly more than those who drank plain tap water…so they gained significantly more weight. A short study on people confirmed that ghrelin levels ended up six times higher in those drinking calorie-free carbonated water.

17-40 Segment 1: A Possible Treatment For Fetal Alcohol Syndrome



Fetal Alcohol Syndrome can cause many physical and mental problems that last a lifetime.  Dr. Eva Redei, Professor of Psychiatry and Behavioral Sciences at Northwestern University, says that most children who grow up with fetal alcohol syndrome usually never live independently because their neurodevelopment was stalled, and if they make it to adulthood they will require help. Babies with the most severe form of FAS are characterized by wide-set eyes, a flattened crease above the upper lip, a low IQ, and other cognitive and behavioral issues. About one percent of children born in the US have a severe form of fetal alcohol syndrome, with two to five percent falling on the fetal alcohol spectrum. But because there is no definitive test, some children are never diagnosed on the spectrum.

Dr. Joanne Rovet of Hospital for Sick Children explains that adults with fetal alcohol syndrome are at risk for mental illness. They also have an increased chance of getting in trouble with the law. About fifty percent of juvenile delinquents had prenatal alcohol exposure.

A study conducted by Dr. Redei on rats indicates that FAS can be treated at birth. Rats were given alcohol and split into two groups, with one group’s babies given a thyroid drug or a diabetic drug like metformin. The other group of babies which wasn’t given medication showed signs of FAS. Both drugs were shown to reduce or reverse the effects of prenatal alcohol exposure. Dr. Redei is now working on starting a human trial.

Researchers continue to search for a brain booster to combat the cognitive effects of advancing age, and they may have found one in human umbilical cord blood. A study in the journal Nature shows that human cord blood injected into old mice significantly improved the function of their brains. Researchers were then able to isolate the responsible factor in the newborn blood, a protein called timp-2. Timp-2 injected into old mice produced the same effects. Researchers say the findings could lead to new treatments of age-related mental decline.

More women who’ve had cancer are having children, but those kids are more likely to be born prematurely, with a below average birth weight. A study in the Journal of the American Medical Association shows that breast cancer treatment produces nearly double the risk for preterm birth later, while cancers such as Hodgkins lymphoma increased the risk by 6%. Doctors don’t know if those children have greater health risks later on in life.

And finally, a study now proves that when people get their pictures taken, most of them say “take my left side. It’s my better side.” And when people view pictures, they perceive the left side of faces to be more expressive. That’s according to a study in the journal Brain and Cognition. Scientists explain that the left side of the face is controlled by the right side of the brain, which is more involved in emotion.

And that’s Medical Notes this week.

            Women who’ve suffered a miscarriage and are trying to get pregnant again might want to think about taking a daily baby aspirin. A study in the Journal of Clinical Endocrinology and Metabolism tested women who had lost a previous pregnancy and scored high for inflammation in the body. Researchers found that those who took a daily low dose aspirin were 31 percent more likely to become pregnant than women who took a placebo and 35 percent more likely to carry the baby to term. However, researchers say it’s too early to recommend aspirin to prevent pregnancy loss. 

            Statistics show that obese girls don’t do as well in school as their thinner counterparts. But a new study in the journal Sociology of Education finds that at least part of the difference may be due to discrimination on the part of their teachers. Researchers say even when they score the same on ability tests, obese white girls receive worse grades than their thinner peers.

            And finally here’s one more thing to put on the list of things to never eat—snow. And it doesn’t matter what color the snow is. A study in the journal Environmental Science, Processes and Impacts finds that snow is remarkably efficient at absorbing particulate air pollution that you find in car exhaust. It’s like a sponge. So catching snowflakes with your tongue may not be as pure as we thought.

And that’s Medical Notes this week.

16-19 Segment 1: Egg Freezing

16-19A Freezing Eggs


Show Synopsis: Freezing eggs in their 30’s allows women to preserve fertility well into their 40’s. The concept was originally meant for women whose fertility was threatened by disease or medical treatment, but today the majority of those having eggs frozen are doing so for social or career reasons. Now egg freezing is even offered as a corporate benefit in some places. Experts discuss the procedure and its uses.
