Female Drinkers Gain Less

1 A Little Wine Keeps Pounds Away

Women who start out at a healthy weight and drink a light or moderate amount of alcohol will gain less weight over time than women who abstain, according to a study in the Archives of Internal Medicine. The study followed more than 19,000 women for 13 years and found that women who didn't drink gained an average of 9 pounds during the study, compared to about 3 pounds for light or moderate drinkers. That amounted to a 30 percent reduction in the risk of becoming overweight for women who consumed one or two alcoholic drinks a day. Red wine in particular seemed to protect women from weight gain, but other studies have shown the same effect doesn't happen in men. And it's not a great idea to start drinking because of this -- alcohol has been linked to an increased risk of breast cancer.

Wider Population is Healthier

2 Vaccinating Kids Helps All of Us

Widespread vaccination of kids against the flu helps keep people of all ages in the wider community healthier, probably because kids are more likely to spread germs around when playing than adults are in their regular activities. Researchers at Canada's McMaster University found 61 percent fewer flu cases in isolated areas where kids got flu vaccines compared to those that didn't. They looked at 46 religious Hutterite communities in Canada, chosen because of their relative isolation. The study proved what's been called "herd immunity," in which people are protected from a virus even if they don't get the vaccine themselves. Researchers say if there's a shortage of vaccine, it should be given to kids first to make herd immunity more successful.

Due To Stem Cell Loss

3 Children’s Learning Abilities Affected by Anesthes

Repeated anesthesia in children can impair their memory, says a Swedish study published in the Journal of Cerebral Blood Flow & Metabolism. Scientists discovered the link between repeated anesthesia and impaired memory by chance while researching the effect of MRIs on memory in animal studies. They found that while magnetic fields didn’t affect memory, anesthesia did. Said Klas Blomgren, researcher, "We found that repeated anesthesia wiped out a large portion of the stem cells in the hippocampus, an area of the brain that is important for memory.” In a previous study they found that physical activity stimulates brain stem cell growth. “Now that we know this, we can come up with treatments that prevent or reverse the loss of stem cells after repeated anesthesia,” said Blomgren.

Not Always Advisable

4 Removal of Ovaries During Hysterectomy Questioned

Each year, about 55 percent of all women undergoing a hysterectomy also have their ovaries removed in a prophylactic procedure known as bilateral oophorectomy. In terms of numbers, about 300,000 of these surgeries are performed per year. Now, an article by William H. Parker, MD, John Wayne Cancer Institute at Saint John's Health Center, Santa Monica, CA, questions the necessity of oophorectomy. After extensive research and follow-up studies of women who’ve had the surgery, Dr. Parker concludes that removal of the ovaries in pre- and post-menopausal women with no additional risk of developing breast or ovarian cancer, can lead to heart disease and bone fractures due to estrogen deficiency. The article appears in the March/April issue of The Journal of Minimally Invasive Gynecology.
