- OBJECTIVES: To assess endothelial function and vascular mechanical properties in normotensive pregnant women with high resistance in the uteroplacental circulation. DESIGN: Cross-sectional prospective study. SETTING: Doppler ultrasound laboratory at university department of obstetrics and gynaecology referral centre for high risk pregnancies. PARTICIPANTS: Forty-two caucasian normotensive pregnant women: 23 with uncomplicated pregnancies and 19 with bilateral uterine artery notches. METHODS: Flow-mediated dilatation of the brachial artery was measured by ultrasonography at 25 gestational weeks. Concentrations of nitrite and nitrate in the plasma were established at 25 and 32 gestational weeks. The elastic properties of the common carotid artery, abdominal aorta and popliteal artery were measured with an ultrasonic echo-tracking system. RESULTS: Flow-mediated dilatation at two minutes after cuff deflation was significantly lower in the bilateral notch group compared with the control group, 8.3% and 13.7%, respectively (P = 0.0007). The ability to sustain vasodilatation was reduced in the bilateral notch group (P = 0.02). Lower values of nitrite and nitrate in the plasma were found at 32 gestational weeks in the bilateral notch group than in the control group (mean 24.76 microM/L (SD 5.6) and 30.93 microM/L (8.2), respectively; P = 0.008). Nitrite and nitrate levels tended to be lower in the bilateral notch group even at 25 gestational weeks (29.45 microM/L (8.3) and 35.73 microM/L (11.0) in the bilateral notch and control group, respectively; P = 0.09). There was no difference in aortic, carotid or popliteal elasticity between the two groups. CONCLUSIONS: Healthy normotensive pregnant women with bilateral uterine artery notches show impaired endothelial function, but no differences in vascular mechanical properties.

- Objective: To test the hypothesis that sub-optimal factors in perinatal care services resulting in perinatal deaths were more common among immigrant mothers from the Horn of Africa, as compared to Swedish mothers. Design: A perinatal audit, comparing cases of perinatal deaths among children of African immigrants residing in Sweden, with a stratified sample of cases among native Swedish women. Setting: Sixty-three cases of perinatal deaths among immigrant east African women delivered in Swedish hospitals in 1990–1996, and 126 cases of perinatal deaths among native Swedish women. Time of death and type of hospital were stratified. Main outcome measures: Sub-optimal factors in perinatal care services, categorised as maternal, medical care, and communication. Results: The rate of sub-optimal factors likely to result in potentially avoidable perinatal death was significantly higher among African immigrants. In the group of antenatal deaths, the OR was 6.2 (CI 1.9-20); the OR for intrapartal deaths was 13 (CI 1.1-166); and the OR for neonatal deaths was 18 (CI 3.3-100), when compared with Swedish mothers. The most common factors were delay in seeking health care, mothers refusing caesarean sections, insufficient surveillance of IUGR (intrauterine growth restriction), inadequate medication, misinterpretation of CTG (cardiotocography), and interpersonal miscommunication. Conclusions: Sub-optimal factors in perinatal care likely to result in perinatal death were significantly more common among east African than native Swedish mothers, affording insight into socio-cultural differences in pregnancy strategies, but also the sub-optimal performance of certain health-care routines in the Swedish perinatal care system.

- OBJECTIVE: To investigate how many women wish to have a caesarean section when asked in early pregnancy, and to identify background variables associated with such a wish. DESIGN: National survey. SETTING: Swedish antenatal clinics. POPULATION: 3,283 Swedish-speaking women booked for antenatal care, at approximately 600 Swedish antenatal clinics, during three weeks spread over one year (1999-2000). METHODS: A questionnaire was mailed shortly after the first antenatal visit. MAIN OUTCOME MEASURES: Women's preferences for mode of delivery. RESULTS: 3,061 women completed the first questionnaire, corresponding to 94% of those who consented to participate after exclusion of reported miscarriages. The background characteristics of the study sample were very similar to a one-year cohort of women giving birth in Sweden during 1999. The result showed that 8.2% of the women would prefer to have a caesarean section. A wish for caesarean section was associated with parity, age, civil status, residential area and obstetric history. Women preferring caesarean section were more depressed and worried, not only about giving birth, but also about other things in life. A multivariate logistic regression model showed three factors being statistically associated with a wish for caesarean section: a previous caesarean section, fear of giving birth and a previous negative birth experience. CONCLUSIONS: Relatively few women wish to have a caesarean section when asked in early pregnancy, and these women seem to be a vulnerable group.

- Objective To compare the effectiveness and safety of the oxytocin antagonist atosiban with conventional beta-adrenergic agonist (beta-agonist) therapy in the treatment of preterm labour. Design Three multinational, multicentre, double-blind, randomised, controlled trials. Setting Hospitals in Australia, Canada, Czech Republic, Denmark, France, Israel, Sweden, and the UK. Population Women diagnosed with preterm labour at 23-33 completed weeks of gestation. Methods Seven hundred and forty-two women were randomised; 733 received atosiban (n = 363; intravenous (iv) bolus dose of 6.75 mg, then 300 mug/minute iv. for 3h and 100 mug/min iv thereafter) or beta-agonist (n 379; ritodrine, salbutamol or terbutaline iv; dose titrated) for at least 18h and rip to 48 hours. Uterine contraction rate, cervical dilatation and effacement were used to assess progression of labour. An all patients treated analysis, using the Cochran-Mantel-Haenszel test, was performed. Main outcome measures Tocolytic effectiveness was assessed in terms of the number of women undelivered after 48 hours and seven days. Safety was assessed in terms of maternal side effects and neonatal morbidity. Results There were no significant differences between atosiban and beta -agonists in delaying delivery for 48h (88.1% vs 88.9%; P = 0.99) or seven days (79.7% versus 77.6%; P = 0.28). Tocolytic effectiveness was also similar in terms of mean [SD] gestational age at delivery (35.8 [3.9] weeks vs 35.5 [4.1] weeks) and mean [SD] birthweight (2491 [813] g versus 2461 [831] g). Maternal side effects, particularly cardiovascular adverse events (8.3% vs 81.2%, P < 0.001) were reported more frequently in women given beta -agonists, resulting in more treatment discontinuations due to side effects (1.1% vs 15.4%, P = 0.0001). No statistical differences in neonatal/infant outcomes were observed with either study medication. Conclusions In the largest study of tocolytic therapy to date, atosiban was comparable in clinical effectiveness to conventional beta-agonist therapy, but was associated with fewer maternal cardiovascular side effects. We conclude that atosiban has clinical advantages over current tocolytic therapy.

- OBJECTIVE: To explore conceptions of obstetric emergency care among traditional birth attendants in rural Guatemala, elucidating social and cultural factors. STUDY: design Qualitative in-depth interview study. SETTING: Rural Guatemala. SAMPLE: Thirteen traditional birth attendants from 11 villages around San Miguel Ixtahuacán, Guatemala. METHOD: Interviews with semi-structured, thematic, open-ended questions. Interview topics were: traditional birth attendants' experiences and conceptions as to the causes of complications, attitudes towards hospital care and referral of obstetric complications. MAIN OUTCOME MEASURES: Conceptions of obstetric complications, hospital referrals and maternal mortality among traditional birth attendants. RESULTS: Pregnant women rather than traditional birth attendants appear to make the decision on how to handle a complication, based on moralistically and fatalistically influenced thoughts about the nature of complications, in combination with a fear of caesarean section, maltreatment and discrimination at a hospital level. There is a discrepancy between what traditional birth attendants consider appropriate in cases of complications, and the actions they implement to handle them. CONCLUSION: Parameters in the referral system, such as logistics and socio-economic factors, are sometimes subordinated to cultural values by the target group. To have an impact on maternal mortality, bilateral culture-sensitive education should be included in maternal health programs.

- Objective To determine the effect of ONO-8815Ly on uterine contractions. Design A randomised, double-blind, placebo-controlled, dose-ascending, cross-over study. Setting Department of Obstetrics and Gynaecology, University Hospital of Lund, Sweden. Population Seventeen, healthy, parous and permanently sterilised women. Methods Intrauterine pressure was recorded on days 1-3 of bleeding of two menstruations. Subjects were intravenously treated with 4 or 8 mug/minute of ONO-8815Ly or placebo for 130 minutes. Intravenous bolus injections of oxytocin, 50 pmol/kg body weight, were given 10 minutes before, during infusion after 60 and 120 minutes and 60 minutes after completion of infusion. The plasma concentrations of ONO-8815Ly were measured in samples obtained immediately before each oxytocin injection. Main outcome measure Area under pressure recording curve (AUC) 10 minutes before and after each oxytocin injection. Results Twelve women, six in each dose group, completed both recordings. Of these, two women of each group were not included in efficacy analysis due to non-responsiveness to oxytocin or missing baseline value. The AUC over 10 minutes before oxytocin injection after 60 minutes of infusion of ONO-8815Ly at 4 and 8 mug/minute was reduced to 21% and 37% of that before infusion, respectively. The AUC after oxytocin at that time amounted to 21% and 19%, respectively, of that before infusion. The activity and responsiveness remained low after 120 minutes but started to return to baseline 60 minutes after stopping infusion. Placebo had no effect. Conclusions ONO-8815Ly is a potent inhibitor of spontaneous uterine contractility in non-pregnant women and it reduces the uterine response to oxytocin injections.
