Folic acid advice has had little impact on birth defects
Recommendations for women planning a pregnancy to take folic acid supplements have had no impact on the number of babies born with neural tube defects, says an international team of researchers.
Recommendations on use of folic acid consumption have had no detectable impact on the incidence of neural tube defects, according to an international study.
Upon reading these headlines and summaries, wouldn't you, as a pregnant woman taking folic acid supplements on the recommendation of your doctor, begin to think that you had been misled and might as well throw away your remaining pills? Doesn't it sound as if the relationship between folic acid deficiency and birth defects has been disproved? Not so! (More)I know that my brother had roseola when he was 14 months old, because I found mention of the episode in one of my father’s journals. Although it was not documented, I assume the rest of us also contracted the disease. Most children do, before they are two years old, often with symptoms so mild they evade diagnosis.
Although roseola was officially described in 1910, and studies in the early 1950’s led scientists to believe that it was caused by a virus, it was not until the 1980’s that the virus was isolated and named: Human Herpes Virus-6 (HHV-6). What was being discovered about this virus would have roused great concern, had not the attention of the scientific and medical communities, and the media, been overwhelmed by the more obvious medical problem of the time: AIDS.

Since amyloid plaques are also present in the brains of people afflicted with the human form of mad cow disease and other spongiform encephalopathies, this finding may be of even wider importance.
Hmmm...perhaps we'll have curry for dinner...or maybe something Thai....Sleep—the new weight loss program!
It's not surprising that the walkers benefitted from their exercise; what is peculiar is the distribution of their improvements. Both uphill and downhill walkers experienced a decrease in their LDL ("bad") cholesterol. Uphill walking also lowered triglyceride levels and increased the body's ability to handle fat. Downhill walking significantly increased the body's ability to handle sugar. Walking uphill did not help with sugar, nor downhill with fats. (More)
For our country—and for ourselves, also. It is appropriate that today's news includes a Dutch study confirming the positive health benefits of optimism. The nine-year study of nearly a thousand men and women between the ages of 65 and 85 found that an optimistic personality contributed significantly to reduced mortality. The effect was most dramatic when cardiovasculary mortality alone was considered. (The above link takes you directly to the Archives of General Psychiatry where the research was published. As might be expected, unfortunately, the news stories circulating differ vastly in accuracy, with some reporting the opposite of the true cardiovascular results.) (More)
Researchers in England have determined that tea inhibits the activity of brain enzymes linked to Alzheimer's disease. They don't know yet if the effect works in vivo, but the report nontheless puts an extra feeling of satisfaction into my morning "cuppa." Both green and black tea have this salubrious effect, although green tea's benefits are more enduring.
These findings are consistent with previous research which demonstrated the importance of intestinal bacteria in the development of a healthy immune system. Babies who experience a normal delivery pick up vaginal, intestinal, and perianal microbes from their mothers. The risk to babies born by C-section includes not only deprivation of normal microbes, but also exposure to the unnatural microbial ecosystem peculiar to a hospital environment.
...to make a man. Or at least it improves the odds significantly, according to a study by Dr. Karen Norberg, a clinical associate at the National Bureau of Economic Research in Cambridge, Massachusetts. "When parents were living together before the birth of one child, that child was 14% more likely to be male than when the parents were not living together before the birth," she reported, according to an article in today's Guardian.
Charles Darwin noted similar findings in 1874, giving some credence to the article's statement that this "is certainly not an effect of any bias from parents against daughters." Otherwise one could easily imagine single mothers preferring to raise daughters; not everyone, but enough to skew the statistics. Sex-selective abortion is frowned upon, but that doesn't prevent it. And it can have a huge impact.
Just ask the Chinese.A study of premature infants suggests that delaying the clamping of the umbilical cord can reduce the need for blood transfusion in babies who are born too soon. A delay of only 30 seconds to two minutes was sufficient to provide significant benefit.
This news led me to search out a much more exhaustive discussion of umbilical cord issues, covering everything from conditions where immediate separation is necessary, to cord blood collection, to the "lotus birth," in which the placenta stays attached until the cord falls off the baby. Parents, midwives, and a few doctors speak out on issues that I had no idea were issues when I gave birth a quarter of a century ago. The concensus of this group is that delayed cord cutting is beneficial for full term babies (and their mothers) as well. Most of the debate seems to be between cutting the cord after the placenta stops pulsating, and waiting until the placenta is delivered.
