For a long time, it's been debated whether taking vitamin D supplements during pregnancy provide particular health benefits. Advocates, backed by some studies, say vitamin D reduces the risk of preeclampsia and gestational diabetes. Others, backed by some studies, say there's no convincing proof. A new analysis of 43 randomized, controlled trials on vitamin D found that, well, the debate will go on. The analysis concluded that many past studies were too small or flawed to produce reliable findings one way or another.

A global initiative, launched in 2012, to improve access to contraceptives for women living in the world's poorest nations appears to be bearing fruit. A new report published by Family Planning 2020 says more than 309 million women and girls are now using a modern method of contraception in 69 targeted countries, up 38.8 million women over the last five years. The biggest gains were in Africa. Researchers say the increased use of contraceptives has prevented millions of unintended pregnancies and unsafe abortions and thousands of maternal deaths.

An estimated 6 million American adults have Alzheimer's disease or mild cognitive impairment, which sometimes is a precursor to AD. The National Institutes of Health predicts that number will jump to 15 million by 2060 as the population ages.
These numbers are higher than previous estimates. Researchers used new methodology that included people with biomarkers or other evidence of possible preclinical AD, but who were not yet impaired by dementia.

Local physicians had concluded that Jane Todd Crawford, 45, of Motley's Glen, Kentucky was pregnant with twins. ) McDowell thought otherwise and instead removed a 22-pound ovarian tumor - in an era without anesthesia.

Q: What is the "Lazarus phenomenon?"
A: In rare, but documented, cases, people who appear to have died (not breathing, no pulse or heart rate, etc) come back to life. Usually the originating event is cardiac arrest, followed by the disappearance of vital signs. But minutes later, the signs return. More formally known as "auto-resuscitation" and poorly understood, a chief factor may be the buildup of pressure in the chest caused by CPR. When efforts to revive fail and signs of life appear gone, CPR stops, pressure declines and the heart restarts on its own. Unfortunately, in the vast majority of cases, the seeming return from the dead is short-lived and the person soon succumbs to heart failure, which may have always been the underlying threat.
