Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

WHO Child Growth Charts


Increased screening of pregnant women and new mothers for major depression and conflicts with intimate partners may help identify women at risk for suicide, a University of Michigan Health System-led analysis of federal data concludes.

Only a small percentage of women who take their own lives are pregnant or have recently become mothers, but their frequent interactions with the health care system may provide important opportunities for providers to intervene if risk factors are better understood, the researchers say.

Their findings were published online this month ahead of print publication in General Hospital Psychiatry.

"We have a more complete picture now of who these women are and what led up to these tragic events," says lead study author Katherine J. Gold, M.D., M.S.W., M.S., assistant professor of family medicine at the U-M Medical School. "These deaths ripple through families and communities and cause a lot of sorrow and devastation."

The study analyzed five years of suicide data from the National Violent Death Reporting System, which was introduced in 2003. The dataset is unique for linking multiple sources of information together to provide details that include demographics, pregnancy status, mental health and substance abuse status, and precipitating circumstances.

More than half of the women who killed themselves had a known mental health diagnosis, with mood disorder being the most common at 95 percent. Nearly half were known to have a depressed mood leading up to the suicide.

"Previous research has shown that depressive disorders affect 14-23 percent of pregnant and postpartum women and anxiety disorders affect 10-12 percent," says study senior author Christie Palladino, M.D., M.Sc., an obstetrician/gynecologist with Georgia Health Sciences University's Education Discovery Institute. "We've known that major depression is a factor in suicide for a long time.

"But this data tells us, for example, that pregnant and postpartum women had a much higher incidence of conflicts with intimate partners than their counterparts," Palladino continues.

Postpartum women were also more likely to have been identified as having a depressed mood in the two weeks prior to suicide than other women, the study found.

Also important, researchers found many similarities that did not vary significantly by pregnancy status: 56 percent of all victims had a known mental health diagnosis; 32 percent had previously attempted suicide; and 28 percent had a known alcohol or substance abuse issue at the time of death.

"Depression and substance use are risk factors for everyone, including pregnant and postpartum women," Gold adds.

The researchers also found that while education level and marital status were very similar across pregnant, postpartum and non-pregnant suicides, Hispanic women were far more likely to take their own lives while pregnant (10 percent of suicides among pregnant women) or within a year of pregnancy (9 percent of postpartum suicides) than when not pregnant (4 percent of non-pregnancy associated suicides).

The researchers acknowledge some inherent limitations of the data. Their sample of 2,083 suicides among women of plausible child-bearing age (15-54), was drawn only from the 17 states where data was available. It is also was impossible to interview the victims and get a full picture of mental health conditions, unreported domestic violence and other precipitating factors.

"As a society, we tend to avoid talking about suicide," Gold says. "But it's important to try to understand and talk about risk factors if we are going to address suicide from a public health perspective."
