CONTEXT A previous report from the Study of Women Across the Nation indicated a rise in dehydroepiandrosterone sulfate (DHEAS) during the menopausal transition using data from three annual visits. OBJECTIVE Our objective was to examine changes in DHEAS with chronological and ovarian aging, expanding the original analyses to include 10 yr of annual data.(More)
In this report, 3029 women between the ages of 42 and 54 yr from five ethnic groups were studied for 2 yr. Log circulating dehydroepiandrosterone sulfate (DHEAS) concentrations were highest among Chinese and Japanese and lowest among African Americans and Hispanics, and this pattern persisted after adjustment for age, smoking, and log body mass index (BMI).(More)
OBJECTIVE To perform a systematic review of the literature to determine whether singleton pregnancies resulting from IVF-ET/GIFT are at higher risk for preterm birth (<37 weeks). DESIGN Literature search and systematic review. SETTING Medical school. INTERVENTION(S) A MEDLINE search (1965-2000) was performed using the terms "premature labor,"(More)
Uterine leiomyomas, or fibroids, are the most common benign tumor in reproductive aged women. Affected women may remain asymptomatic or may report symptoms related to abnormal uterine bleeding, infertility, or pelvic pain and pressure. Depending on a patient's symptomatology and reproductive plans, treatment options include expectant management, medical(More)
Despite the documented importance of the protein hormone relaxin in reproduction in various mammalian species, the role of relaxin in human reproduction is poorly understood, largely because of the lack of studies in women or in suitable non-human primate models. Here we describe the establishment of a non-human primate model of early human pregnancy and(More)
OBJECTIVES Hispanics have less favorable cardiovascular risk profiles relative to other groups, although little is known regarding variability in risk profiles according to country of origin. Our goal was to examine the association of cardiovascular risk factors with country of origin and acculturation in a cohort of middle-aged Hispanic women. SETTING(More)
Fifty-five patients with osteogenesis imperfecta (OI) were studied to determine the extent to which the peripheral auditory mechanisms share in the connective tissue lesion. Ninety-two unaffected relatives and 43 control subjects were also studied. Subjects were divided into age groups younger than and older than 30 years. Hearing loss, most frequently(More)
Inflammatory disorders account for a significant percentage of gynecologic disease, particularly in reproductive age women. Inflammation is a basic method by which we respond to infection, irritation, or injury. Inflammation is now recognized as a type of nonspecific immune response, either acute or chronic. In gynecology, inflammation leads to anatomic(More)
OBJECTIVE To evaluate the reproductive outcomes of early human gestations exposed to GnRH agonist (GnRH-a). Gonadotropin-releasing hormone agonist is commonly used as an adjunct to ovulation induction regimens, and sometimes early pregnancies are inadvertently exposed to the drug. There has been concern regarding possible teratogenic effects of GnRH-a on(More)
