Women More Likely to Avoid Abnormal Babies

Thank You~Lauren Neergaard, Associated Press


Women Look Away

Puzzling new research suggests women have a harder time than men looking at babies with facial birth defects. It's a surprise finding.

Psychiatrists from the Harvard-affiliated McLean Hospital, who were studying perceptions of beauty, had expected women to spend more time than men cooing over pictures of extra-cute babies. Nope.

Instead, the small study being published Wednesday raises more questions than it can answer.

First the background: The McLean team already had studied men and women looking at photos of adults' faces on a computer screen. The participants rated facial beauty, and could do various keystrokes to watch the photos longer. A keystroke count showed men put three times more effort into watching beautiful women as women put into watching handsome men.

Lead researcher Dr. Igor Elman wondered what else might motivate women. Enter the new baby study.
This time 13 men and 14 women were shown 80 photos of babies, 30 of whom had abnormal facial features such as a cleft palate, Down syndrome or crossed eyes. Participants rated each baby's attractiveness on a scale of zero to 100, and used keystrokes to make the photo stay on the screen longer or disappear faster.

Women pressed the keys 2.5 times more than men to make photos of babies with the facial abnormalities disappear, researchers reported in PLoS One, a journal of the Public Library of Science. That's even though they rated those babies no less attractive than the men had.

"They had this subliminal motivation to get rid of the faces," said Elman, who questions whether "we're designed by nature to invest all the resources into healthy-looking kids."


Both genders spent equal time and effort looking at photos of the normal babies.

The study couldn't explain the gender disparity. Elman noted that previous work has linked child abandonment and neglect to abnormal appearance, and even asked if the finding might challenge the concept of unconditional maternal love.

That's too far-reaching a conclusion, cautioned Dr. Steven Grant of the National Institute on Drug Abuse, which funded the study.

The work is part of broader research into how we normally form attachments and what can make those attachments go awry, work that tests if what people say matches what they do.

"Common sense would tell you one thing," Grant said. "This doesn't fit with common sense. It raises a question."

Ten Tips for a Healthy Pregnancy

Thank You Dr. Jacob Teitelbaum

As mothers tend to sacrifice during their lives to meet their children's needs, a mother's body will give up its own essential nutrients to provide health and growth for her developing baby. Unfortunately, the Standard American Diet (S.A.D.) is often so nutritionally deficient that even this sacrifice does not guarantee adequate nutrition for the unborn baby.

Fortunately, there are a number of tips that, if followed during pregnancy, can help both baby and mother stay healthy and vital!

Here is my top 10 list for ensuring a healthy pregnancy. It includes recommendations on nutrition, vitamins, minerals and other common-sense tips that can lead to a happier, healthier and more vital pregnancy:

1. Zinc
Inadequate zinc is the most common and problematic deficiency during pregnancy. Zinc is critical for two reasons: proper growth and for developing a healthy immune system for the baby. Studies suggest that inadequate zinc may even cause immune deficiency in the next generation (i.e., your grandchild) as well. Be sure to get at least 15 milligrams per day of zinc in your diet, which can be found in high protein foods such as meat and beans.

2. Folic Acid
Getting enough folic acid is critical both before and during pregnancy to help assure proper growth and to prevent birth defects. It is present in deep green, leafy vegetables. Women should get at least 400 to 800 micrograms per day.

3. Magnesium
Magnesium deficiency is routine in the American diet and can increase the possibility of high blood pressure and seizures during pregnancy, a condition known as eclampsia. To prevent this deficiency, take 200 milligrams of magnesium in the glycinate form daily. Whole grains, green leafy and other vegetables and nuts are good sources of magnesium. Taking the proper amount of magnesium a day also helps to decrease the leg cramps and constipation often experienced during pregnancy. In addition, magnesium is critical for more than 300 other body functions and will generally help you to feel a lot healthier.

4. B Vitamins
These are critical for energy, mental clarity and to prevent depression. B vitamins have also been found to improve pregnancy-related complications such as gestational diabetes. Taking 200 milligrams a day of vitamin B6 can improve the health of those women suffering from this form of diabetes. But please note that only women who develop gestational diabetes during pregnancy should take this high level of B vitamins, and should drop the level of consumption to 100 milligrams per day during the last month. For all other soon-to-be moms, take approximately 25 to 50 milligrams a day of B vitamins and plenty of vitamin B12 for normal nerve function.

5. Fish Oils
The human brain is made predominantly of DHA, an essential fatty acid found in fish oils. Perhaps this is why there is an old wives' tale about fish being brain food. Regardless, DHA deficiency is very common and it is critical that pregnant women get adequate fish oils so that their baby can develop healthy and optimal brain tissue. DHA may also decrease the risk of postpartum depression. Unfortunately, though, the FDA has raised concerns about high mercury levels in the same deep sea fish (salmon and tuna) that have the highest levels of these oils. An excellent alternative for those who'd rather not risk it is to take one half to one tablespoon of Eskimo 3 fish oil. This is a special form of fish oil that actually tastes good (most do not), and has been tested to make sure that it does not have mercury or other problematic compounds.

6. Calcium
Ideally, pregnant women should ingest 1,500 milligrams of calcium per day. It is best to take this at night (it helps with sleep) in the liquid, powdered or chewable form. Many calcium tablets are simply chalk and do not dissolve in the stomach, and therefore are not absorbed properly. Each cup of milk or yogurt contains 400 milligrams of calcium.

7. Iron
Approximately 18 to 36 milligrams of iron per day can be helpful. Interestingly, iron deficiency can sometimes cause infertility. Also, pregnant women who don't get enough iron are at risk for anemia, fatigue, poor memory and decreased immune function.

8. Water
Be sure to drink plenty of water. When pregnant, blood volume can increase about 30 percent and it is easy to become dehydrated. If your mouth or lips are dry, drink more! Adequate salt is also helpful in preventing dehydration (less so if you have problems with fluid retention).

9. Check Your Thyroid
Millions of women suffer from an underactive metabolism, also known as hypothyroidism, which often goes undiagnosed. This results in fatigue, weight gain and simply feeling like you've run out of gas. Hypothyroidism accounts for more than 6 percent of miscarriages and can be cause for learning disabilities in the child. Treating a low thyroid is both safe and easy during pregnancy. The earlier it is treated the better. Either once you start trying to get pregnant, or as soon as you know you're pregnant, take a Thyroid Stimulating Hormone (TSH) blood test to check your thyroid. Most doctors do not yet know that the TSH has to be less than three — anything above and you need treatment — so look at the test result yourself (many doctors still use the dangerous and outdated criteria of a TSH over five being abnormal). If you like, you can get a lab requisition for a TSH to take to your lab by visiting www.Vitality101.com (click on "online program" then on "Laboratory Requisition Form"). If you were on thyroid medication before getting pregnant, it is normal to increase the dose during pregnancy (the TSH should be kept between .5 and 2.0). If your doctor is not familiar with the new guidelines, he or she can send an email to the Web site above and a copy of the guidelines will be sent to them.

10. Things for Pregnant Women to Avoid
A few cautions for pregnant women: avoid taking more than 8,000 units of vitamin A per day. And don't partake in anything that can raise your body temperature too high (hot tubs, saunas or steam rooms). These have been implicated as possibly increasing the risk for birth defects. Most pregnant women are also, of course, aware that smoking, drugs and alcohol should all be avoided during pregnancy. Exercise, on the other hand, has been shown to be very beneficial and results in babies and moms that are quite healthy.

Bed Bug Weapon Uses Insect's Own Juice

Thank You; Emily Sohn, Discovery News

Researchers have enlisted a new weapon against bed bugs: their own chemical signals. It's first time scientists have used any insect's alarm pheromones as a method of control.

While the new technique probably won't single-handedly solve anyone's bed bug woes, experts say, the research may add to our arsenal of tools for fighting what has become a disturbing nuisance for a growing number of people.

"To control bed bugs, there's not going to be one easy solution," said Joshua Benoit, an entomologist at Ohio State University in Columbus. "We are trying to encourage people to find new and creative ways to kill bed bugs."

Bed-bug infestations have been on the rise in recent years, Benoit said, probably because people travel so much. All it takes is one pregnant female hopping a ride in a suitcase for a new crop of insects to invade homes and apartment buildings.

The tiny critters don't spread diseases, but a single person can easily get a few hundred bites in one night. Those chomps cause intense itching and even scarring in some people.

So far, there is no ideal way to get rid of bed bugs. Pesticide treatments can be expensive, invasive, toxic, and often ineffective. Already, the insects have developed resistance to some of the most common chemicals used to fight them.

In an effort to get the upper hand, Benoit experimented with alarm pheromones -- the chemicals that bed bugs release when they're disturbed or in danger. In turn, their comrades get excited and start scurrying around.

Benoit and colleagues mixed synthetic versions of bed-bug alarm pheromones with desiccant dust, a pesticide that works by drying insects out. In order to work, the bugs need to run directly through the dust.

The researchers placed varying concentrations of these mixtures in Petri dishes and in small enclosures that contained hiding places for the insects. Then they added bed bugs.

Their results, published in the Journal of Medical Entomology, showed that mixtures of alarm pheromones and desiccant dust killed up to 50 percent more bed bugs than did desiccant dust alone. The idea is that the pheromones get the bugs to move around more, making them more likely to run through the dust, which is relatively non-toxic and inexpensive.

"This is the first study of its kind to use alarm pheromones in this manner," Benoit said, "for any insect."

It's still way too soon to recommend that people run out and buy alarm pheromones (which are synthesized for other purposes, including as food preservatives). Outside the confines of a plastic dish, getting bed bugs to run around like crazy is not necessarily a good thing, said Michael Potter, an urban entomologist at the University of Kentucky, Lexington. Bed bugs are notoriously good at getting behind baseboards, inside walls, and into other cracks and crevices.

"Some might run into the apartment next door," Potter said. "Some might run into inaccessible areas."

In one recent incident in Columbus, Benoit said, bed bugs had infested 23 out of 24 units in an apartment building. Residents had to leave their homes for a week while the building was fumigated. Even then, there was no guarantee that the treatment killed all the bugs.

The incident illustrates how important it is to continue learning more about the inner workings of these pests.

"Any new work on bed bugs," Potter said, "is interesting work."

WHO Declares Swine Flu Pandemic

The World Health Organization told its member nations it was declaring a swine flu pandemic Thursday -- the first global flu pandemic in 41 years as infections climbed in the United States, Europe, Australia, South America and elsewhere.

In a statement sent to member countries, WHO said it decided to raise the pandemic warning level from phase 5 to 6 -- its highest alert level -- after holding an emergency meeting on swine flu with its experts.

"At this early stage, the pandemic can be characterized globally as being moderate in severity," WHO said in the statement, urging nations not to close borders or restrict travel and trade. "(We) remain in close dialogue with influenza vaccine manufacturers."

Health officials from Scotland, Indonesia and Thailand previously announced the agency would declare a swine flu pandemic -- a global epidemic -- on Thursday after a teleconference with leading flu experts. Officials at U.N. missions in Geneva also said they expected the imminent announcement of a pandemic.

"It is likely in light of sustained community transmission in countries outside of North America -- most notably in Australia -- that level 6 will be declared," Scotland's Health Secretary Nicola Sturgeon told Scottish lawmakers, adding it would be Thursday.

Indonesian health minister Siti Fadilah Supari said she had been notified by WHO that "today will be declared to be phase 6."

The last pandemic -- the Hong Kong flu of 1968 -- killed about 1 million people. Ordinary flu kills about 250,000 to 500,000 people each year.

Since swine flu first emerged in Mexico and the United States in April, it has spread to 74 countries around the globe.

On Wednesday, WHO reported 27,737 cases including 141 deaths. Most cases are mild and require no treatment, but the fear is that a rash of new infections could overwhelm hospitals and health authorities -- especially in poorer countries.

The long-awaited pandemic announcement is scientific confirmation that a new flu virus has emerged and is quickly circling the globe. It will trigger drug makers to speed up production of a swine flu vaccine and prompt governments to devote more money to containing the virus.

In May, several countries urged WHO not to declare a pandemic, fearing it would spark mass panic.

Panic has already gripped Argentina, where so many people worried about swine flu flooded into hospitals this week that emergency health services have collapsed. Last month, a bus arriving in Argentina from Chile was stoned by people who thought a passenger on it had swine flu. Chile has the most swine flu cases in South America.

In Hong Kong, the government on Thursday ordered all kindergartens and primary schools closed for two weeks after a dozen students tested positive for swine flu.

In Australia, swine flu cases jumped to more than 1,000 on Monday and reached 1,260 by late Wednesday.

WHO says its pandemic announcement would not mean the situation was worsening, since no mutations have been detected in the virus to show it is getting more deadly.

In Edinburgh, Sturgeon told lawmakers that a WHO announcement means countries should immediately activate their pandemic plans.

"A move to level 6 is not a verdict on the severity of the virus," she said. "It simply means that the extent of global spread now fulfills the definition of a pandemic."

Armpits: 'Rain Forests' For Bacteria

Thank You, Lauran Neergaard

Eeeww. There's a zoo full of critters living on your skin -- a bacterial zoo, that is. Consider your underarm a rain forest. Healthy skin is home to a much wider variety of bacteria than scientists ever knew, says the first big census of our co-inhabitants. And that's not a bad thing, said genetics specialist Julia Segre of the National Institutes of Health, who led the research.

Sure they make your sneakers stinky, "but they also keep your skin moist and make sure if you get a wound that (dangerous) bacteria don't enter your bloodstream," she said. "We take a lot for granted in terms of how much they contribute to our health."

People's bodies are ecosystems, believed home to trillions of bacteria, fungi and other microbes that naturally coexist in the skin, the digestive tract and other spots. But scientists don't have a good grasp of which microbes live where, much less which are helpful, even indispensable, in maintaining health.

The NIH's "Human Microbiome Project" aims to change that, recruiting healthy volunteers to learn what microbes they harbor so scientists can compare the healthy with diseases of microbes gone awry -- from acute infections to mysterious conditions like psoriasis or irritable bowel syndrome.

The skin research, published in Friday's edition of the journal Science, is part of that project. Scientists decoded the genes of 112,000 bacteria in samples taken from a mere 20 spots on the skin of 10 people. Those numbers translated into roughly 1,000 strains, or species, of bacteria, Segre said, hundreds more than ever have been found on skin largely because the project used newer genetic techniques to locate them.

Topography matters, a lot, the researchers reported. If a moist, hairy underarm is like a rain forest, the dry inside of the forearm is a desert. They harbor distinctly different bacteria suited to those distinctly different environments. In fact, the bacteria under two unrelated people's underarms are more similar than the bacteria that lives on one person's underarm and forearm.

Mom's advice to wash behind your ears notwithstanding, that spot contained the least diverse bacteria -- 19 species on average. The most diverse spot: the forearm, which averaged 44 species.

How many are supposed to live there? That's not clear yet. Some certainly could be tourists, picked up as we go about our day. When researchers re-checked five of these volunteers a few months later, the bacteria in some spots -- the moist nostril and groin, for example -- proved pretty stable while other spots, including the forearm, had changed quite a bit.

Which are good bugs, and which bad? That depends. A common skin bacteria is Staph epidermidis, found all over the body. Segre said it helps protect us from its nasty cousin, Staph aureus, which about a third of people are thought to carry on the skin or in their nose even if they have no active infection.

But, back to topography, Staph epidermidis itself can harm if it gets under the skin; it's a common trigger of catheter-caused infections.

The research helps lay the groundwork for what doctors really want to know: What's different in the skin of people with diseases such as eczema or psoriasis? Those studies are about to begin, says Dr. Martin Blaser of New York University Langone Medical Center, who is leading one on psoriasis and performed some first-step studies of skin bacteria that helped lead to the NIH's census.

Then there's the scrubbing question, society's antibacterial obsession.

"There's an all-out assault on our normal skin organisms," Blaser noted. "In trying to get rid of the bad guys, are we getting rid of the good guys?"

Segre hopes knowing there are so many bacteria alters how people think about the relationship.

"I'm a mother of two small children; I believe very strongly in sanitation, washing your hands," Segre said. But, "we have to understand that we live in harmony with bacteria and they are part of us as super-organisms ... and not just conceive of bacteria as bad and germs and smelly."
