Risk For Premature Birth May Be Heightened By Pre-Pregnancy Depressed Mood
Researchers trying to uncover why premature birth is a growing problem in the United States and one that disproportionately affects black women have found that pre-pregnancy depressive mood appears to be a risk factor in preterm birth among both blacks and whites.

ACOG Issues New Guidelines On Fetal Monitoring To Resolve Inconsistencies In Interpretation
The American College of Obstetrics and Gynecology recently published new guidelines on electronic fetal monitoring in an attempt to increase consistency in the way physicians interpret and act on the results, the New York Times reports. Electronic fetal monitoring, which was introduced in the 1970s, is used during labor for more than 85% of the four million infants born alive in the U.S. annually, the Times reports. According to the Times, use of fetal monitors became standard obstetrical practice before it was known if the benefits outweighed the risks. The new guidelines refine the meaning of various readings from fetal monitors and could help doctors make better decisions about whether to intervene during labor.According to experts, the widespread adoption of fetal monitoring has produced both negative and positive consequences, including significant increases in caesarean deliveries and the use of forceps during vaginal deliveries. Monitoring has not been found to reduce the risk of either cerebral palsy or fetal death resulting from inadequate oxygen to the fetal brain, as it was intended to do. Furthermore, lawyers commonly use monitoring results to support malpractice cases that might have little merit, which in turn has driven rising malpractice insurance costs and prompted some obstetricians to stop delivering infants.The new guidelines divide monitor readings into three categories to help doctors interpret readings more consistently. The old guidelines had two categories -- reassuring and non-reassuring -- and it was up to the obstetrician to determine whether a non-reassuring reading required intervention. Under the new guidelines, the first category applies when tracings of the fetal heart rate are normal and no specific action is required. The second category is for indeterminate tracings that require evaluation, continuous surveillance and re-evaluation. Obstetricians treating patients in this category should consider other clinical factors that could affect the fetus and whether the patient could be safely moved to category one, according to Catherine Spong of the Eunice Kennedy Shriver National Institute of Child Health and Human Development, which produced recommendations on which the guidelines are based. The final category is for abnormal tracings that require immediate evaluation and efforts to reverse the abnormal heart rate. The Times reports that more refinements to the guidelines are expected to be released in 2010 (Brody, New York Times, 7/7).

National Marrow Donor Program Increasing Efforts To Attract Minority Donors
The National Marrow Donor Program, a not-for-profit group that manages a national registry for potential bone marrow donors, is using social networking sites to attract donors from minority communities, the Wall Street Journal reports. The process of finding a genetic match for a bone marrow transplant is often more difficult for minorities or people who identify themselves as multiracial because patients and donors must be genetically compatible. According to the Journal, a white patient has an 88% chance of finding a match, while the odds of most minorities finding a match can be as low as 60%. The odds of some minorities actually receiving a transplant can be as low as 20% because of other factors such as access to care in their communities, the Journal reports. About seven million U.S. residents already have signed up for the national registry -- recently renamed Be the Match -- and the program also has increased outreach to younger potential donors through social networking Web sites, such as Facebook and MySpace (Landro, Wall Street Journal, 5/27).

Evidence Challenges Effectiveness Of Embryo Screening For Older Women

There is growing evidence that a procedure for identifying chromosomal abnormalities in embryos prior to in vitro fertilization is ineffective at helping older women become pregnant, the Wall Street Journal reports. The procedure -- known as pre-implantation genetic screening, or PGS -- is performed in dozen of U.S. fertility clinics and sometimes marketed to older women as a way to increase the odds of a healthy live birth. PGS involves extracting a single cell from a six-cell embryo and inspecting it for chromosomal abnormalities known as aneuploidies; unaffected embryos can then be implanted through IVF. Women older than age 35 have a higher risk of aneuploidies, in which embryos have fewer or more than the usual number of 23 pairs of chromosomes. Aneuploidies can trigger early miscarriage or certain genetics conditions, such as Down syndrome. Most medical experts agree that embryo screening is capable of significantly reducing the risk of Down syndrome and other serious chromosome-related illnesses. However, evidence from several studies increasingly suggests that the procedure does not increase older women"s chances of healthy live births. The American Society for Reproductive Medicine released an initial opinion about PGS in 2007, saying that available evidence does not support the use of embryo screening to increase live birth rates in older women. Andrew La Barbera, scientific director of the society, said, "Since that time, there have been several more trials that have reached the same conclusion." Another shortcoming is that most clinics can only test for fewer than half of the 23 chromosomes, meaning that many defects can go undetected. However, medical experts say that the use of PGS has increased in the two years since ASRM issued its recommendations. According to the Journal, PGS can add more than $2,000 to the roughly $10,000 cost of one IVF cycle. Very few health insurers cover PGS, though some pay for IVF. Some experts contend that studies showing a lack of clinical benefit from PGS do not use more efficient biopsy techniques that can prevent damage to the embryo. Santiago Munne, scientific director for Reprogenetics, said that the treatment is "effective." In a 2007 study, Munne and colleagues used PGS to reduce the rate at which patients miscarried. However, the chances of a woman getting pregnant largely were unchanged, which the authors said could be attributed to the small number of study participants (Naik, Wall Street Journal, 6/1).
