BACKGROUND The reduction of maternal deaths is a key international development goal. Evidence-based health policies and programmes aiming to reduce maternal deaths need reliable and valid information. We undertook a systematic review to determine the distribution of causes of maternal deaths. METHODS We selected datasets using prespecified criteria, and(More)
OBJECTIVE To analyse preterm birth rates worldwide to assess the incidence of this public health problem, map the regional distribution of preterm births and gain insight into existing assessment strategies. METHODS Data on preterm birth rates worldwide were extracted during a previous systematic review of published and unpublished data on maternal(More)
Rates of caesarean section are of concern in both developed and developing countries. We set out to estimate the proportion of births by caesarean section (CS) at national, regional and global levels, describe regional and subregional patterns and correlate rates with other reproductive health indicators. We analysed nationally representative data available(More)
Despite the call for universal access to reproductive health at the 4th International Conference on Population and Development in Cairo in 1994, sexual and reproductive health was omitted from the Millennium Development Goals and remains neglected (panel 1). Unsafe sex is the second most important risk factor for disability and death in the world's poorest(More)
RU 486 and three of its metabolites (RU 42633-monodemethyl, RU 42848-didemethyl, and RU 42698-hydroxymetabolite) were determined by HPLC in plasma from nine non-pregnant and 36 pregnant women. Each non-pregnant subject took an oral dose of RU 486 (25, 100, 400 and 600 mg consecutively) once per menstrual cycle. Six of the nine women also received a dose of(More)
In vitro fertilization and embryo transfer is now an established treatment for certain forms of human infertility. High success rates have been reported following oocyte recovery and fertilization in vitro, the only major remaining difficulty being the high failure rate (80%) of implantation after replacement of the embryo into the mother. One possible(More)
The spontaneous pattern of pituitary gonadotropins and ovarian steroids and their response to dynamic tests were measured in 12 women with polycystic ovarian syndrome (PCO) and the results compared to those from 6 normal women during the early follicllar phase of the cycle (controls). As judged by serial measurements of urinary total estrogen and(More)
A multicenter study of the Lactational Amenorrhea Method (LAM) was carried out to test the acceptability and efficacy of the method. Additionally, the data are used to test new constructs for improvement of method criteria. A protocol was designed at the Institute for Reproductive Health (IRH), Department of Obstetrics and Gynecology, Georgetown University(More)
