Researchers have found a possible link between sleep-disordered breathing and reduced fetal movements in pregnant women with preeclampsia. An article published in the January 2013 issue of the journal Sleep details the results of a study of patients with preeclampsia who received nasal continuous positive airway pressure (CPAP).

A cross-sectional National Institutes of Health (NIH)-supported study published in Menopauseshows that changes in cognitive function associated with menopause aren’t linear and, in fact, decline is most common in the first year after the final menstrual period.

Nearly all ob/gyns consider the bimanual pelvic examination a very important part of the well-woman checkup, and sometimes perform the examination unnecessarily in asymptomatic women, according to the results of a nationwide survey.

Researchers at the Wake Forest School of Medicine in Winston-Salem, North Carolina, have found that regaining weight after losing it may be harmful to the health of postmenopausal women.

A study published online by the journal Environmental Research found that 55.8% of women ages 16 to 49 had blood levels of lead, mercury, and polychlorinated biphenyls (PCBs) that exceeded the median.

Noninvasive fetal diagnosis

Instead of invasive procedures such as chorionic villus sampling or amniocentesis, definitive, noninvasive testing for fetal chromosomal abnormalities has long been the "holy grail" in obstetrics. It now appears practical to achieve prenatal genetic diagnosis using cell-free fetal dna in maternal blood.

The effects of exercise during and after cancer treatment are different, according to the findings of a new systematic review. Researchers concluded that exercise has a palliative effect in patients during cancer treatment and a recuperative effect after treatment.

A cross-sectional nationwide Canadian epidemiological study suggests that marriage rather than cohabitation may have psychosocial benefits for pregnant women. Published in theAmerican Journal of Public Health, the results point to a need for research on maternal and child health that distinguishes between married and unmarried cohabiting women.

A study published online by the Archives of Internal Medicine reports that women who are screened for the BRCA gene and found not to be carriers often undergo ovarian Ca screening, despite the fact that the lifetime risk of developing ovarian cancer is only 1% to 2% in the general population.

In a head-to-head trial, chromosomal microarray analysis was shown to be more effective than traditional karyotyping in prenatal diagnosis. Results of the study-which is the largest of its kind and which received support from the National Institutes of Child Health and Human Development-reflect the accuracy, efficacy, and incremental yield of the technologies.

Researchers who prospectively examined the association between cigarette smoking/smoking cessation and the risk of sudden cardiac death (SCD) have found that even “light-to-moderate” smokers (those who smoke 1 to 14 cigarettes daily) are at increased risk. The study looked at 101,018 women participating in the Nurses' Health Study without known coronary heart disease (CHD), stroke, and cancer beginning in 1980. (The Nurses' Health Study has collected biannual health questionnaires from US female nurses since 1976.)

Human papillomavirus (HPV) detection among older patients may be due to reactivation of the virus, not a new acquisition, according to new research. This fact, as well as the aging of the baby boomer generation-the first generation to have experienced the sexual revolution of the 1960s and 1970s-means that perimenopausal women who are found to have HPV may have acquired it years before.
