Medical induction of labor increases risk of amniotic-fluid embolism
A Canadian population-based cohort study has revealed that medical induction of labour increases the risk of amniotic-fluid embolism. The study was led by Dr. Michael Kramer, Canadian Institutes of Health Research (CIHR) Senior Investigator from McGill University. Amniotic-fluid embolism (AFE) is a rare, but serious and even fatal maternal complication of delivery. While its cause is unknown, it is one of the leading causes of maternal mortality in developed countries, accounting for seven of 44 direct maternal deaths in Canada in the period 1997-2000.

Miscarriage significantly associated with increasing paternal age
In a study conducted at Columbia University's Mailman School of Public Health and the New York Psychiatric Institute researchers found that increasing paternal age is significantly associated with increased rates of spontaneous abortion, a pregnancy loss occurring before twenty weeks of gestation. Results indicate that as the male partner ages there is a steady increase in rate of miscarriage. Women with partners aged 35 or older had nearly three times as many miscarriages as compared with women conceiving with men younger than 25 years of age. This finding is independent of the woman's age and not explained by other factors such as diabetes, smoking, or previous spontaneous abortions, and adds to the growing realization of the importance of paternal characteristics for successful reproductive outcome.

Clinical examination not sensitive enough to detect breech babies
The routine examination doctors use to check if a baby is lying in the correct position before birth is not sensitive enough, concludes a study published on bmj.com today. The authors suggest that there is room for improvement by all pregnancy care providers. The position of a baby in the womb in late pregnancy is important because if it is not lying in the normal head-down position (known as cephalic presentation) vaginal delivery may be difficult or impossible. Diagnosis of non-cephalic presentation after the onset of labour is associated with increased complications and death. Fetal presentation is usually assessed by palpating the abdomen, but little is known about the accuracy of this in late pregnancy. So researchers in Australia decided to examine the diagnostic accuracy of this procedure.

Preeclampsia risk reduced by regular multivitamins near time of conception
Women who are considering becoming pregnant may significantly reduce their risk of developing a common life-threatening complication called preeclampsia by taking a multivitamin supplement regularly three months before conception and during the first trimester of pregnancy. This finding is being reported in a University of Pittsburgh study available online now through an "advance access" feature of the American Journal of Epidemiology.

Pregnancy Complications Still High For Women With Diabetes
The risk of death and major birth defects are still high in babies born to women with diabetes, despite an international strategy to raise standards of diabetes care, say researchers in a study published on bmj.com. They also warn that these problems will get worse as the number of young women diagnosed with type 1 and type 2 diabetes continues to rise. Researchers analysed deaths shortly after birth (perinatal mortality) and congenital anomalies in babies born to women with type 1 or type 2 diabetes who delivered between 1 March 2002 and 28 February 2003 in England, Wales, and Northern Ireland.

Researchers identify protein associated with severe preeclampsia
Building on their earlier discovery which found that elevated levels of the sFlt1 placental protein leads to the onset of preeclampsia, researchers at Beth Israel Deaconess Medical Center (BIDMC), in collaboration with a research team from The Hospital for Sick Children, Toronto, have identified a second protein which, in combination with sFlt1, escalates preeclampsia to a severe and life-threatening state. These new findings, reported in the June 4, 2006 on-line issue of Nature Medicine, provide another critical piece of information about this puzzling disease, which complicates five percent of all pregnancies worldwide and is a major cause of maternal and fetal mortality, particularly in developing nations.

Study Challenges Myth that Sex Late in Pregnancy Hastens Birth
A new study debunks the widely held belief that engaging in sexual intercourse during the final weeks of pregnancy can hasten labor and delivery. In fact, just the opposite was true in 93 women studied at Ohio State University Medical Center. Women who were sexually active in the final three weeks of their pregnancies carried their babies an average of 39.9 weeks, compared to average delivery at 39.3 weeks among women who abstained from sexual activity at term.

Daughters of Indian immigrants continue trend of giving birth to small babies
U.S.-born Asian-Indian women are more likely than their Mexican-American peers to deliver low birth weight infants, despite having fewer risk factors, say researchers at Lucile Packard Children's Hospital and Stanford's School of Medicine. The finding confirms previous research that showed a similar pattern in more recent immigrants, and suggests that physicians should consider their patients' ethnic backgrounds when planning their care.

Stress levels could lead to miscarriages
Pregnant women who exhibit signs of stress are three times more likely to face the risk of miscarriage, says a study. Around 31 to 89 percent of all conceptions result in miscarriage, earlier studies indicated. Most studies begin when women notice they are pregnant, about six weeks after conception. Most miscarriages, however, are known to happen during the first three weeks of pregnancy.

Why, throughout the world, more boys are born?
The longer it takes to get pregnant, the more chance there is of having a boy, finds a study in this week�s BMJ. Dutch researchers analysed data for 5,283 women who gave birth to single babies between July 2001 and July 2003. Among the 498 women who took longer than 12 months to get pregnant, the probability of male offspring was nearly 58%, whereas the proportion of male births among the 4,785 women with shorter times to pregnancy was 51%.

An analysis of the prepregnancy body mass index of more than 79,000 women in eight counties of Western New York who became pregnant between 1999 and 2003 found that the number of women who were overweight when they became pregnant increased by 11 percent and the number who were obese increased by 8 percent over that time period.

Down Syndrome now Detectable at 11 Weeks
A new study from Columbia University Medical Center researchers at NewYork-Presbyterian Hospital/Columbia of more than 38,000 pregnant women at 15 U.S. centers demonstrates the high accuracy of non-invasive screening for Down syndrome (also known as trisomy 21) in the first trimester of pregnancy, at 11 weeks. The findings are a significant advantage over the current standard screening, a blood test performed in the second trimester of pregnancy. Published this week in the New England Journal of Medicine (Nov. 10, 2005 issue), the study is known as the FASTER trial (First and Second Trimester Evaluation of Risk). It was funded by a $13 million grant from the National Institutes of Health and the National Institute of Child Health and Human Development � one of the largest ever grants for an obstetrical study.
