To assess the involvement of ovarian-derived regulatory proteins in FSH modulation, we compared FSH, inhibin A, inhibin B, activin A, and follistatin (FS) in 79 women from the following five groups: young cycling, older cycling, perimenopause (PERI), spontaneous menopause (PM), and surgical menopause receiving estrogen (OVX+ET). Although inhibin B varied as expected by ovarian function, no group differences were observed in activin A, barring a tendency for an increase in PERI, while FS 288 was lower in the PERI, PM, and OVX+ET groups and negatively correlated with advancing age.

OBJECTIVE: To distinguish the effects of midlife aging from early postmenopause on vitamin K measures, bone formation biomarkers, and bone density. DESIGN: Cycling older volunteers (CO; 40-52 years, n = 19) were compared to cycling young (CY; 20-30 years, n = 21) and untreated, age-matched women in the early postmenopause years (EPM; 40-52 years, mean years PM = 2.8 +/- 0.5, n = 19). We assessed sex steroids, vitamin status (phylloquinone, 25-hydroxyvitamin D, retinol), osteocalcin (OC), percentage of undercarboxylated osteocalcin (%ucOC), and bone mineral density (BMD) at the spine and hip with dual-energy x-ray absorptiometry. RESULTS: CO women had similar estradiol and vitamin status as CY women, but lower OC (0.64 +/- 0.04 vs 0.97 +/- 0.08 nmol/L, P = 0.01) and BMD at the total hip (1.0038 +/- 0.032 vs 1.1126 +/- 0.030 g/cm2, P = 0.02). In the two older groups, BMD was similar at all sites, but OC was elevated in the EPM women (1.10 +/- 0.10 vs 0.64 +/- 0.04 nmol/L, EPM vs CO, P = 0.001). Although phylloquinone was highest in the EPM women, %ucOC was also higher when compared with all cycling women (21.9 +/- 1.7% vs 17.4 +/- 0.9%, n = 40; P = 0.02). CONCLUSIONS: Premenopausal women show reduced BMD despite normal estrogen profiles. %ucOC may be a specific bone marker of the early postmenopause in healthy women.

OBJECTIVE: To describe the trends in ectopic pregnancy mortality in Michigan from 1985 through 1999 and compare to those of previous time periods. METHODS: We reviewed all cases of maternal mortality from ectopic pregnancy in Michigan from 1985 through 1999. We extracted data from death certificates, hospital inpatient and emergency department records, medical examiner autopsy reports, and reviews by the Michigan Maternal Mortality Study. The Health Data Development Section of the Michigan Department of Community Health provided data on live births and maternal deaths RESULTS: Of the 268 pregnancy-related deaths, 16 (6%) were caused by complications of ectopic pregnancy. Mean age at death was 27 (+/- 6) years. Thirteen deaths were to African-American women and 3 were to white women (P < .01). African-American women had an ectopic mortality ratio 18 times higher than white women (3.25/100,000 live births, compared with 0.18/100,000) Three cases of pregnancy-related death due to complications of ectopic pregnancy were considered preventable, and 2 others were of unknown preventability. CONCLUSION: Ectopic pregnancy treatment has changed in the last 20 years coincident with a decrease in maternal mortality from ectopic pregnancy. Sudden death was the presenting scenario in 75% of nonpreventable ectopic deaths, an increase from previous analyses. A large racial disparity is apparent. Ideally, pregnancy care should start as soon as possible after the first missed menses; however, systemwide changes are needed to create a new norm promoting early access to pregnancy care and promoting education and testing to rule out pregnancy abnormalities.
