Objective: To study the effect of the childbirth experience on the likelihood and interval to a subsequent live birth., Design: Retrospective analysis of a 7-year cohort., Setting: Childbirths in Helsinki University Hospital delivery units., Participants: All parturients giving birth to a term and living baby from a single pregnancy in Helsinki University Hospital delivery units from January 2012 to December 2018 (n=120 437). Parturients delivering their first child (n=45 947) were followed until the birth of a subsequent child or the end of 2018., Main Outcome Measure: The interval to a subsequent childbirth connected to the experience of the first childbirth was the primary outcome of the study., Results: A negative first childbirth experience decreases the likelihood of delivering a subsequent child during the follow-up (adjusted HR=0.81, 95% CI 0.76 to 0.86) compared with those experiencing the first childbirth as positive. For parturients with a positive childbirth experience, the median interval to a subsequent delivery was 3.90 years (3.84-3.97) compared with 5.29 years (4.86-5.97) after a negative childbirth experience., Conclusion: The negative childbirth experience influences reproductive decisions. Consequently, more focus should be placed on understanding and managing the antecedents of positive/negative childbirth experiences., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Childbirth experience has been shown to depend on the mode of delivery. However, it is unclear how labour induction influences the childbirth experience in different modes of delivery. Thus, we assessed the childbirth experience among mothers with spontaneous and induced labours., Design: A retrospective cohort study., Setting: Childbirths in four delivery hospitals in Helsinki and Uusimaa District, Finland, in 2012-2018., Sample: 95051 childbirths excluding elective caesarean sections., Methods: Obstetric data combined to maternal childbirth experience measured by Visual Analogue Scale (VAS) was analysed with univariate linear modelling and group comparisons. The primiparas and multiparas were analysed separately throughout the study due to the different levels of VAS., Main Outcome Measures: Maternal childbirth experience measured by VAS., Results: The negative effect of labour induction on the childbirth experience was discovered in each mode of delivery. Operative deliveries were perceived more negatively when they were preceded by labour induction. The rate of poor childbirth experience (VAS≤5) was higher for mothers with labour induction (ORs varying from 1.43 to 1.77) except in emergency caesarean sections. The negative effect of labour induction was smaller than the effect of mode of delivery, while successful vaginal delivery with induction (mean PRIMI =8.00 [95% CI 7.96-8.04], mean MULTI =8.50 [8.47-8.53]) was perceived more positive than operational deliveries with spontaneous labour (means PRIMI ≤7.66 [7.61-7.70], means MULTI ≤7.96 [7.89-8.03]). However, labour induction more than doubled the risk of caesarean section for both primiparas and multiparas., Conclusions: Labour induction generates more negative experiences for both primiparas and multiparas. The negative effect of labour induction is detected for all modes of delivery, being worst among labour induction resulting in operative delivery. The parturients facing cumulative obstetric interventions require special support and counselling during and after delivery., (© 2022. The Author(s).)

Objectives: The aim of this study was to analyse the relation between the used labour pain relief and childbirth experience measured by Visual Analogue Scale (VAS)., Design: A retrospective cohort study., Setting: Childbirth in five Helsinki University Hospital delivery units from 2012 to 2018., Primary Outcome Measure: Childbirth experience measured by VAS and classified in three groups (negative VAS=1-5, positive VAS=6-8 and highly positive=9-10)., Results: The use of epidural or non-epidural compared with non-medical pain relief methods decreased the likelihood to experience highly positive childbirth for primiparous (adjusted OR (aOR) EPIDURAL =0.64, 95% CI 0.57 to 0.73; and aOR NON-EPIDURAL =0.76, 95% CI 0.66 to 0.87) and multiparous (aOR EPIDURAL =0.90, 95% CI 0.84 to 0.97 and aOR NON-EPIDURAL =0.80, 95% CI 0.74 to 0.86) parturients. The effects of epidural differed between primiparas and multiparas. In multiparas epidural was associated with decreased odds for experiencing negative childbirth compared with the non-medical group (aOR=0.70, 95% CI 0.57 to 0.87), while the effect of epidural was considered insignificant in primiparas (aOR=1.28, 95% CI 0.93 to 1.77)., Conclusion: While the use of medical-epidural and non-epidural-pain relief methods were not associated with odds for experiencing negative childbirth in primiparas, using epidural helps to avoid negative experience in multiparas. However, the odds for experiencing highly positive childbirth were decreased if the parturients used any medical pain relief for both primiparas and multiparas. Consequently, the effect of pain relief on the childbirth experience is strongly confounded by indication. Thus, the use of pain relief per se plays a limited role in the complex formation of the overall childbirth experience., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: To explore how the time of delivery influences childbirth experience., Design: A retrospective cohort study., Setting: Childbirth in the four Helsinki and Uusimaa Hospital District hospitals, Finland, from 2012 to 2018., Participants: 105 847 childbirths with a singleton live fetus., Main Outcome Measures: Childbirth experience measured by Visual Analogue Scale (VAS)., Results: The major difference in average childbirth experience measured by VAS was between primiparas (8.03; 95% CI 8.01 to 8.04) and multiparas (8.47; 95% CI 8.45 to 8.48). Risk ratio (RR) of the low VAS (≤5) was 2.3 when primiparas were compared with multiparas. Differences in VAS between distinct periods were found in two stages: annual and time of day. The decrease in VAS from 2012-2016 to 2017-2018 in primiparas was from 7.97 (95% CI 7.95 to 7.99) to 7.80 (95% CI 7.77 to 7.83) and from 2014-2016 to 2017-2018 in multiparas from 8.60 (95% CI 8.58 to 8.61) to 8.49 (95% CI 8.47 to 8.52). Corresponding RRs of low VAS were 1.3 for primiparas and 1.2 for multiparas. Hourly differences in VAS were detected in primiparas between office hours 08:00-15:59 (7.97; 95% CI 7.94 to 7.99) and other times (night 00:00-07:59; 7.91; 95% CI 7.88 to 7.94; and evening 16:00-23:59; 7.90; 95% CI 7.87 to 7.92). In multiparas differences in VAS were detected between evening (8.52; 95% CI 8.50 to 8.54) and other periods (night; 8.56; 95% CI 8.54 to 9.58; and office hours; 8.57; 95% CI 8.55 to 8.59)., Conclusion: The maternal childbirth experience depended on the time of delivery. Giving birth during the evening led to impaired childbirth experience in both primiparas and multiparas, compared with delivery at other times. The impact of labour induction on childbirth experience should be further examined. The reorganisation of delivery services and the reduction of birth preparations might affect annual VAS. VAS is a simple method of measuring the complex entity of childbirth experience, and our results indicate its ability to capture temporal variation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objective: To study women's apprehensions, understanding and experiences of counselling concerning a screen-positive result in screening for fetal chromosomal defects., Methods: A questionnaire study including different steps of the prenatal screening process was carried out in Helsinki University Hospital. Women's experiences concerning counselling immediately after a screen-positive result and during further examinations in the Fetal Medicine Unit (FMU) were analyzed., Results: 143 women filled in the questionnaire. Less than half of the women considered the primary counselling after a screen-positive result to be explicit (43.9%) and sufficient (43.1%). In the FMU, 88.3% and 89.8% of women were satisfied with the explicitness and sufficiency of counselling. Most women (75%) experienced worry before further examinations but less than half (45%) had considered their personal values concerning diagnostic tests. Half (50.5%) of women expected the worry to continue even if diagnostic tests turn out normal. Most (81%) women were aware that diagnostic tests are voluntary and were confident (85.3%) with their decision to participate., Conclusions: After a screen-positive result, women have unanswered questions, experience anxiety and confusion. The possibility of an abnormal screening result is not seriously considered beforehand. To enable an informed consent for prenatal screening, improvements in prescreening counselling during the first visits of antenatal care need to be made., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To evaluate the impact of time of birth on adverse neonatal outcome in singleton term hospital births., Materials and Methods: Medical Birth Register Data in Finland from 2005 to 2009. Study population was all hospital births (n = 263,901), excluding multiple pregnancies, preterm births <37 weeks, major congenital anomalies or birth defects, and antepartum stillbirths. Main outcome measures were either 1-minute Apgar score 0-3, 5-minute Apgar score 0-6, or umbilical artery pH <7.00, and intrapartum and early neonatal mortality. We calculated risk ratios (ARRs) adjusted for maternal age and parity, and 95% confidence intervals (CIs) to indicate the probability of adverse neonatal outcome outside of office hours in normal vaginal delivery, in vaginal breech delivery, in instrumental vaginal delivery, and in elective and nonelective cesarean sections. We analyzed different size-categories of maternity hospitals and different on-call arrangements., Results: Instrumental vaginal delivery had increased risk for mortality (ARR 3.31, 95%CI; 1.01-10.82) outside office hours. Regardless of hospital volume and on-call arrangement, the risk for low Apgar score or low umbilical artery pH was higher outside office hours (ARR 1.23, 95%CI; 1.15-1.30). Intrapartum and early neonatal mortality increased only in large, nonuniversity hospitals outside office hours (ARR 1.51, 95%CI; 1.07-2.14)., Conclusions: Compared to office hours, babies born outside office hours are in higher risk for adverse outcome. Demonstration of more detailed circadian effects on adverse neonatal outcomes in different subgroups requires larger data.

Purpose: To evaluate whether a trial of planned vaginal breech labor affects neurologic development in children., Methods: This is a nationwide, Finnish, population-based record linkage study. An odds ratio with 95% confidence intervals was used to estimate the relative risk that a child delivered by planned vaginal breech labor would be diagnosed with adverse neurodevelopmental outcome (cerebral palsy, epilepsy, intellectual disability, sensor neural developmental outcome, hyperactivity, speech and language problems) at the age of 4 years. The reference group were children born by planned cesarean section., Results: During a study period of 7 years, 8374 infants were delivered in breech position. Among them, 3907 (46.7%) had an attempted labor and 4467 (53.3%) infants were delivered by planned cesarean section. There were no differences in the neurodevelopmental outcome. In the planned vaginal labor group, 133 (3.4%) children had an abnormal neurodevelopmental outcome at the age of 4 years compared to 142 (3.2%) in the planned cesarean section group., Conclusion: The absolute risk of abnormal neurological outcome in breech deliveries at term was low, regardless of planned mode of birth. Planned vaginal breech labor did not increase the risk for abnormal neurological outcome compared to planned cesarean section.

Objectives: Our aim was to demonstrate the influence of increased number of low-risk deliveries on obstetric and neonatal outcome., Study Design: The study hospital was Kätilöopisto Maternity Hospital in Helsinki. Simultaneously, we studied all three delivery units in the Helsinki region in the population-based analysis. The study population was singleton hospital deliveries occurring between 2011 and 2012, and 2014-2015. The study hospital included 11 237 and 15 637 births and the population-based group included 28 950 and 27 979 births. We compared outcome measures in different periods by calculating adjusted odds ratios (AOR). Main outcome measures were induced delivery, mode of delivery, third or fourth degree perineal tear, Apgar score at five minutes <7, umbilical artery pH <7.00, transfer to higher level of neonatal care, neonatal antibiotic treatment, respiratory support of the neonate, hospitalization of the neonate >7 days, and perinatal death., Results: In the study hospital, induction rate increased from 22.4% to 24.8% (AOR 1.06, 95% CI; 1.00-1.12) while in the population-based analysis the rate decreased from 22.2% to 21.5% (AOR 0.96, 95% CI; 0.92-1.00). Percentage of neonatal transfers, low Apgar scores, and severe perineal tears increased both in study hospital and in population-based group. Changes in operative delivery rate and other adverse perinatal outcomes were statistically insignificant., Conclusions: Increasing the volume of a delivery unit does not compromise maternal or neonatal outcome. Specific characteristics of a delivery unit affect the volume outcome association., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Introduction: The awareness of the incidence and timing of postpartum venous thromboembolic events guides the use of thromboprophylaxis. Our aims were to assess the incidence and mortality of venous thromboembolic events and identify its associated risk factors during different postpartum periods., Material and Methods: A population-based controlled cohort study by combining four large registers in 2001-2011. All women with a recent delivery were identified. The incidence, risk factors and mortality of venous thromboembolic events 0-180 days after delivery were assessed by using all healthy delivered women as the control group. The incidence was compared with that of the nonpregnant women., Results: Among the 634 292 delivered women, 1169 had venous thromboembolic events 0-180 days postpartum. The incidence of venous thromboembolic events was highest during the first week postpartum: 37-fold compared with nonpregnant women, declining to two-fold immediately after that. Almost half of the venous thromboembolic events occurred between 43 and 180 days postpartum. The incidence of venous thromboembolic events was four-fold compared with that of nonpregnant women. Three venous thromboembolic events-related deaths occurred. Older age, higher body mass index, thrombophilia, multiple pregnancy, gestational diabetes, anemia, chorioamnionitis, threatening premature birth, in vitro fertilization with ovarian hyperstimulation, primiparity, cesarean section, cardiac/renal diseases, and varicose veins were associated with an increased risk for postpartum venous thromboembolic events. The risk remained elevated for 180 days in women with thrombophilia, cesarean section, multiple pregnancy, varicose veins, and cardiac disease., Conclusions: The risk of venous thromboembolic events remained elevated compared with that of the nonpregnant women after the usually defined postpartum period (6 weeks). The results might assist in selecting women in need of thromboprophylaxis., (© 2017 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To investigate mortality in the non-pregnant fertile female population, and mortality during pregnancy and up to 1 year after the end of pregnancy, in Finland from 2001 to 2012 and compare the results with those of 1987-2000., Design: Retrospective cohort study., Setting: Finland., Population: 10 427 deceased women of reproductive age (15-49)., Methods: Pregnancy outcomes were categorised into: ongoing pregnancy or birth, miscarriage or ectopic pregnancy and termination of pregnancy. Mortality was calculated per 100 000 pregnancies. The mortality rate of the non-pregnant female population of fertile age was calculated per 100 000 person-years, and the results were compared with those of 1987-2000., Main Outcome Measures: Pregnancy-associated mortality during pregnancy and up to 1 year after the end of pregnancy. Mortality of non-pregnant, fertile-age, female population., Results: The age-adjusted mortality rate during pregnancy and within 1 year after the end of pregnancy was 28.4/100 000 pregnancies, and it had significantly decreased compared with the period 1987-2000 [risk ratio (RR) 0.75 (95% CI, 0.65-0.88)]. Mortality in non-pregnant fertile-age females was 48.1/100 000 person-years. Mortality for diseases and medical conditions during and after pregnancy decreased by 26% [RR 0.74 (95% CI, 0.59-0.92)] and for external causes by 23% [RR 0.77 (95% CI, 0.62-0.95)]. The mortality rate for suicides was 3.3/100 000 in ongoing pregnancies and pregnancies ending in birth while it was 21.8/100 000 after termination of pregnancy and 10.2/100 000 among non-pregnant women., Conclusions: In comparison with earlier decades, pregnancy-associated mortality has decreased in Finland., Tweetable Abstract: Mortality decreases among pregnant women and within 1 year after pregnancy in Finland., (© 2016 Royal College of Obstetricians and Gynaecologists.)

Objective: To assess risk factors for adverse perinatal and neonatal outcomes in "well-selected" singleton vaginal breech deliveries at term., Methods: During the time span from January 2008 up to April 2015 a total of 786 singleton term breech deliveries with a planned vaginal delivery were identified in a retrospective observational study at Helsinki University Central Hospital, Finland. The study's end point was a composite of adverse perinatal and neonatal outcomes. Infants with an adverse outcome were compared to all spontaneous singleton vaginal breech deliveries with normal perinatal and neonatal outcomes. A multivariate logistic regression model was used to analyze associations between adverse neonatal outcomes and several variables. The secondary outcome was the severe morbidity rate according to the criteria of the term breech trial., Results: An adverse neonatal outcome was recorded for 38 (4.8%) infants. According to the study the second delivery stage lasting <40 min [adjusted odds ratio (aOR): 0.34, 95% confidence interval (95% CI): 0.15-0.79] was associated with lower odds and had a protective effect against adverse outcomes. Epidural anesthesia (aOR: 2.88, 95% CI: 1.08-7.70) was associated with higher adverse outcomes. The incidence rate of severe morbidity was 1.3% (10/787)., Conclusion: Adverse neonatal outcomes in well-selected breech deliveries are associated with a prolonged second delivery stage lasting >40 min and with epidural anesthesia.

Purpose: The aim of this study was to estimate whether breech presentation at term was associated with known individual obstetric risk factors for adverse fetal outcome., Methods: This was a retrospective, nationwide Finnish population-based cohort study. Obstetric risks in all breech and vertex singleton deliveries at term were compared between the years 2005 and 2014. A multivariable logistic regression model was used to determine significant risk factors., Results: The breech presentation rate at term for singleton pregnancies was 2.4%. The stillbirth rate in term breech presentation was significantly higher compared to cephalic presentation (0.2 vs 0.1%). The odds ratios (95% CIs) for fetal growth restriction, oligohydramnios, gestational diabetes, a history of cesarean section and congenital fetal abnormalities were 1.19 CI (1.07-1.32), 1.42 CI (1.27-1.57), 1.06 CI (1.00-1.13), 2.13 (1.98-2.29) and 2.01 CI (1.92-2.11)., Conclusions: The study showed that breech presentation at term on its own was significantly associated with antenatal stillbirth and a number of individual obstetric risk factors for adverse perinatal outcomes. The risk factors included oligohydramnios, fetal growth restriction, gestational diabetes, history of caesarean section and congenital anomalies.

Background: Vaginal breech delivery is associated with adverse perinatal outcome. The aim of this study was to identify factors associated with adverse perinatal outcome in term breech pregnancies, and to provide clinicians an aid in selecting women for a trial of vaginal labor with the fetus in breech position., Methods: We conducted a retrospective, nationwide, Finnish population-based case-control study. All planned singleton vaginal deliveries at term with the fetus in breech position between the years 2005 and 2014 were analyzed. The study's end point was a composite set of adverse perinatal outcomes. All infants with an adverse outcome were compared to the infants with normal outcomes. A multivariate logistic regression model was used to analyze the data., Results: An adverse perinatal outcome was recorded for 73 (1.5%) infants. According to the study results fetal growth restriction (adjusted odds ratio, 2.94; 95% CI, 1.30-6.67), oligohydramnios (adjusted odds ratio, 2.94; 95% CI, 1.15-7.18), a history of cesarean section (adjusted odds ratio, 2.94; 95% CI, 1.28-6.77, gestational diabetes (adjusted odds ratio, 2.89; 95% CI, 1.54-5.40), epidural anesthesia (adjusted odds ratio, 2.20; 95% CI, 1.29-3.75) and nulliparity (adjusted odds ratio, 1.84; 95% CI, 1.10-3.08) were associated with adverse perinatal outcome., Conclusions: Adverse perinatal outcome in planned vaginal breech labor at term is associated with fetal growth restriction, oligohydramnios, previous cesarean delivery, gestational diabetes, nulliparity and epidural anesthesia.

Introduction: In this study, we have assessed the changes in pregnancy outcomes following the implementation of national guidelines for gestational diabetes mellitus (GDM). These national guidelines changed the screening policy from risk-based to comprehensive screening., Material and Methods: We designed a retrospective register-based cohort study based on the data from the Finnish Medical Birth Register and Hospital Discharge Register including 34 794 singleton births in 2006-2008 and 36 488 in 2010-2012. Maternal characteristics and pregnancy outcomes were analyzed., Results: Overall, 29.6% of mothers underwent an oral glucose tolerance test in 2006-2008 compared with 59.7% in 2010-2012. The prevalence of GDM increased from 7.2 to 11.3% and was highest among obese women (body mass index ≥30 kg/m 2 ) (from 30.0 to 34.7%; p < 0.001). The proportion of insulin-treated women remained unchanged (12.5/12.3%; p = 0.70). The main pregnancy outcomes for the women with GDM were the increased usage of oxytocin (19.5/40.0%, p < 0.001), increased number of inductions (27.2/33.0%; p < 0.001) and reduced birthweight (mean ± SD: 3647 ± 575 g/3567 ± 575 g). Healthy and unscreened women displayed similar results. Children of both women with GDM and healthy screened women had fewer admissions to the neonatal intensive care unit (16.3%/12.1%; p < 0.001) and less asphyxia (11.3%/6.3%; p < 0.001). However, the rates of cesarean delivery (26.5%/25.4%, p = 0.31), resuscitation (2.6%/2.0%; p = 0.12), and perinatal mortality (1.2‰/3.1‰, p = 0.11) among women with GDM did not change, whereas the number of hypoglycemia cases increased (2.3%/5.2%; p < 0.001)., Conclusions: In conclusion, glucose tolerance tests were performed twice as often as a result of the implementation of the national GDM guidelines, but this comprehensive screening practice did not improve pregnancy and neonatal outcomes., (© 2016 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To evaluate the effect of a rapid PCR-based group B streptococcus (GBS) test on length of stay in hospital among newborns, antibiotic use, and GBS-early-onset-disease (EOD) incidence., Methods: We conducted a before and after service evaluation including term deliveries between 1st January and 12th November 2014 (6688 deliveries). Length of stay in the hospital, GBS-EOD incidence and antibiotic use were evaluated., Results: We recorded three confirmed and 74 possible cases of GBS-EOD in Phase 1, and 85 possible cases in Phase 2. In newborns with suspected infection, the introduction of the rapid test was related to a decreased length of stay on the pediatric care unit by 1.16 days (p = 0.01), and an increase in the length of stay on the mother-and-baby ward by 1.11 days (p < 0.001). No increase in antibiotics was noted., Conclusion: The introduction of a point of care test was associated with a reduction in length of stay in the pediatric care unit, without an increase in antibiotic use. This test could improve the accuracy of GBS colonization detection, and help to prevent intrapartum transmission as no verified GBS-EOD cases were recorded with the intrapartum PCR algorithm.

Objective: To assess the association between pregnancy-associated placental protein A (PAPP-A) levels in the first trimester of pregnancy and adverse pregnancy outcomes., Method: A retrospective study included data from a group of patients in the first trimester of pregnancy with PAPP-A levels below 0.3 multiples of median who attended the Helsinki University Hospital, Finland, between January 1, 2009 and December 31, 2012; an age-matched control group of patients with PAPP-A levels 0.9-1.1 multiples of median was also enrolled. The incidences of adverse pregnancy outcomes in the two groups were compared., Results: There were 961 patients included in each of the groups. Significantly increased risks of aneuploidies (odds ratio [OR] 116.0; 95% confidence interval [CI] 16.2-836.6) and spontaneous abortion (OR 7.7; 95% CI 2.7-22.0) were observed among patients with low PAPP-A (both P<0.001). Preterm delivery (OR 2.5, 95% CI 1.8-3.5), pre-eclampsia (OR 10.9, 95% CI 4.3-27.6), and small for gestational age neonates (OR 4.9, 95% CI 3.2-7.5) were also observed more frequently among patients with low PAPP-A (all P<0.001). There were 9 (0.9%) stillbirths recorded among patients with low PAPP-A and none recorded in the control group., Conclusion: Low PAPP-A was associated with adverse pregnancy outcomes and aneuploidy. These risks should be considered when planning follow-up for patients with low PAPP-A pregnancies., (© 2016 International Federation of Gynecology and Obstetrics.)

Objective: The aim of the study was to analyze the risk of adverse pregnancy outcome in three subgroups with extremely low maternal pregnancy-associated plasma protein-A (PAPP-A), that is, <0.3 multiples of median (MoM) at the first trimester screening., Method: A cohort of 961 pregnancies with PAPP-A levels < 0.3 MoM at the first trimester combined screening was followed up during the study period of January 2009 to December 2012. The incidences of adverse outcomes was determined in three subgroups with PAPP-A levels < 0.1 MoM, 0.1 to 0.2 MoM, and 0.2 to 0.3 MoM, respectively., Results: The risks of aneuploidy and spontaneous abortion increased with decreasing PAPP-A levels (p < 0.001), but no difference was detected in the rate of structural anomalies among the three groups. Rates of preterm delivery (p < 0.001) and birth weight < 2 standard deviation below the mean (p < 0.001) increased with decreasing PAPP-A levels. The rates of preeclampsia, stillbirth, and cesarean delivery were not significantly different across the three subgroups., Conclusion: The risks of aneuploidy, spontaneous abortion, preterm delivery, and small for gestational age newborn increased with decreasing PAPP-A. © 2016 John Wiley & Sons, Ltd., (© 2016 John Wiley & Sons, Ltd.)

Objectives: The purpose of this study was to evaluate pregnancies with isolated short fetal femur and humerus on second-trimester sonography. Short fetal long bones are known to be associated with aneuploidy and structural anomalies. In this study, we wanted to show the risk of adverse pregnancy outcomes in euploid and nonanomalous pregnancies., Methods: Singleton pregnancies with short femur and humerus were included. Pregnancies with normal fetal bone lengths and age-matched mothers were selected as controls., Results: The study group included 30 pregnancies with short fetal femur and humerus, and the control group included 60 normal pregnancies. The overall odds ratio for an adverse pregnancy outcome in the study group was 24.9. Preterm delivery occurred significantly more frequently (odds ratio, 20.8; P < .001), and one-third of pregnancies were complicated by preeclampsia. In the group with short long bones, the odds ratio for a pathologic umbilical Doppler flow pattern was 45.2 (P < .001), and birth weight was significantly lower (P < .001). Also, 3 (10.3%) stillbirths and 4 (13.3%) cases of early neonatal death were recorded in this group. These complications were not recorded in the control group. The risk of emergency cesarean delivery was significantly higher in the group with short long bones (odds ratio, 11.8; P < .001)., Conclusions: The risk of adverse pregnancy outcomes is significant in euploid and nonanomalous pregnancies with isolated short long bones. Close follow-up is needed during pregnancy., (© 2016 by the American Institute of Ultrasound in Medicine.)

Objective: The aim of our study was to introduce outpatient induction of labor by Foley catheter, and to compare outcomes and preferences between in-patients and outpatients., Study Design: This clinical cohort study was conducted in Helsinki University Hospital between January 2011 and January 2012. A total of 485 women scheduled for induction of labor by Foley catheter were included. The main outcome measures were cesarean delivery rate, and maternal and neonatal infectious morbidity. Maternal satisfaction of outpatients was measured after delivery., Results: Two hundred and four (42.1%) women were managed as outpatients and 281 (57.9%) women as in-patients. The rates of cesarean delivery, and maternal or neonatal infections did not differ between outpatients and in-patients. Of the outpatients, 85.3% were satisfied., Conclusion: Induction of labor by Foley catheter appears suitable for outpatients, and resulted in no differences in cesarean delivery or infection rates compared with in-patients. Most women were satisfied with the outpatient induction.

Introduction: In contrast to unfractionated heparin (UFH), use of low-molecular weight heparin (LMWH) during pregnancy has not been reported to be associated with a significant decrease in bone mineral density (BMD). The aim of this study was to investigate whether long-term use of LMWH during pregnancy is associated with subsequent decrease in BMD or with increased number of osteoporotic fractures., Materials and Methods: In this observational cohort study BMD was measured by dual energy X-ray absorptiometry (DEXA) 4-7years after the last delivery in 152 women. Ninety-two women had prolonged LMWH-exposure during pregnancy - 75 as prophylaxis and 17 as treatment for venous thromboembolic event (VTE). Dalteparin and enoxaparin were the LMWH-preparations used. Sixty women without LMWH-exposure served as controls. A questionnaire about lifestyle factors and medical history was filled out by the subjects., Results: Lumbar spine BMD in the LMWH users was lower than that in the controls both in the prophylactic group (1.22g/cm(2) vs. 1.27g/cm(2); p=0.03), and in the treatment group (1.20g/cm(2) vs. 1.27g/cm(2); p=0.07). BMD in femoral neck did not differ between the LMWH-users and controls. However, after adjusting for potential confounding factors, LMWH-exposure did not remain associated with decreased BMD in lumbar spine. Use of contraceptive pills was positively associated with BMD in lumbar spine. Incidence of osteopenia was 13% in the LMWH-group and 8% in the control-group, (p=0.4). No osteoporosis or osteoporotic fractures were found., Conclusions: Prolonged use of LMWH during pregnancy was not associated with subsequent decrease in BMD, osteopenia, osteoporosis, or osteoporotic fractures., (Copyright © 2016 Elsevier Ltd.

Objectives To compare the Foley catheter and misoprostol for induction of labor in term women with premature rupture of membranes. Study Design A randomized controlled trial was performed in three university hospitals in Finland between March 2012 and September 2014. A total of 202 term women with ruptured membranes >18 hours, singleton pregnancies in cephalic presentation, unfavorable cervix, and no prior cesarean section were enrolled. Participants were randomly allocated to induction of labor by Foley catheter or oral misoprostol in a 1:1 ratio. All women received prophylactic antibiotics. The main outcomes were cesarean section and maternal and neonatal infections. Results Labor induction by Foley catheter or misoprostol showed no difference in cesarean delivery rates (23.6 vs. 18.2%; odds ratio [OR], 1.39; 95% confidence interval [CI], 0.69-2.82; p = 0.36), maternal intrapartum infections (2.2 vs. 2%; OR, 1.12; 95% CI, 0.15-8.9; p = 1.00), postpartum infections (1.1 vs. 2.0%; OR, 0.55; 95% CI, 0.05-6.18; p = 1.00), or neonatal infections (1.1 vs. 5.1%; OR, 0.21; 95% CI, 0.24-1.87; p = 0.22). The total time from induction to delivery was similar (1,311 vs. 1,435 minutes; p = 0.31) in the two groups. Conclusions Foley catheter or misoprostol can both be used for induction of labor in women with term premature rupture of membranes., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objective: The aim of this study is to evaluate whether induction of breech delivery at term is feasible and safe for mother and child compared with spontaneous vaginal breech delivery., Study Design: A total of 268 singleton term breech deliveries with an attempted vaginal delivery were identified in a single-center retrospective observational study. Out of these, 73 cases had an induction of labor for various medical and obstetric reasons and were compared to 195 spontaneous singleton breech deliveries. The main outcome measure was the mode of delivery. Secondary outcomes included maternal and neonatal morbidity and mortality., Results: The vaginal delivery rate in the induction group was 64.4% compared with 80% in the spontaneous delivery group. No statistical differences were observed between the two delivery groups regarding neonatal and maternal morbidity and mortality., Conclusions: The vaginal delivery rate was significantly lower in induced than in spontaneous breech deliveries. The neonatal and maternal morbidity and mortality rates were similar implying that induction in breech delivery is an option and it is time for clinical reappraisal.

Objective: To evaluate the influence of delivery unit size and on-call staffing in the performance of low-risk deliveries in Finland., Study Design: A population-based study of hospital size and level based on Medical Birth Register data. Population was all hospital births in Finland in 2005-2009. Inclusion criteria were singleton births (birth weight 2500g or more) without major congenital anomalies or birth defects. Additionally, only intrapartum stillbirths were included. Birthweights and maternal background characteristics were adjusted for by logistic regression. Main outcome measures were intrapartum or early neonatal mortality, neonatal asphyxia and newborns' need for intensive care or transfer to other hospital and longer duration of care. On-call arrangements were asked from each of the hospitals., Results: Intrapartum mortality was higher in units where physicians were at home when on-call (OR 1.25; 95% CI 1.02-1.52). A tendency to a higher mortality was also recorded in non-university hospitals (OR 1.18; 95% CI 0.99-1.40). Early neonatal mortality was twofold in units with less than 1000 births annually (OR 2.11; 95% CI 0.97-4.56) and in units where physicians were at home when on-call (OR 1.85; 95% CI 0.91-3.76). These results did not reach statistical significance. No differences between the units were found regarding Apgar scores or umbilical cord pH., Conclusion: The differences in mortality rates between different level hospitals suggest that adverse outcomes during delivery should be studied in detail in relation to hospital characteristics, such as size or level, and more international studies determining obstetric patient safety indicators are required., (Copyright © 2016 Elsevier Ireland Ltd.

Objective: This study aims to estimate the occurrence of emergency peripartum hysterectomy (EPH) and to quantify its risk factors in connection with the mode of delivery and the obstetric history of patients at the Helsinki University Central Hospital, Finland., Methods: In a retrospective, matched case-control study we identified 124 cases of EPH from 2000 to 2010 at our hospital. These were matched with 248 control patients., Results: The incidence rate of EPH was 9.9/10,000. Patients whose current delivery was vaginal, and had a cesarean section (CS) in their history had a six-fold risk for EPH. Women who underwent their first CS had a nine times higher risk, while patients who currently underwent CS and had a history of previous CS, had a 22 times higher risk. Those who experienced prostaglandin-E1 induction had a five-fold risk. Maternal age >35 years, previous curettage, and twin pregnancy were identified as significant risk factors. In 41 cases, interventions to reduce bleeding were performed., Conclusion: Obstetric emergency training and guidelines for massive hemorrhage should be established in any delivery department. Moreover, all possible precautions should be taken to avoid the first CS if it is obstetrically unnecessary. Induction with prostaglandin-E1, maternal age >35 years, previous curettage, twin pregnancies, and early gestation were identified as risk factors for EPH.

Background: Induction of labour is associated with increased risk for caesarean delivery among nulliparous women. The aims of this study were to evaluate the risk factors for caesarean delivery and to investigate the risk of maternal and neonatal infections in nulliparous women undergoing induction of labour by Foley catheter., Methods: This clinical retrospective study of 432 nulliparous women with singleton pregnancy and intact amniotic membranes at or beyond 37 gestational weeks scheduled for induction of labour by Foley catheter was conducted over the course of one year, between January 2012 and January 2013, in Helsinki University Hospital. The main outcome measures were caesarean section rate and maternal and neonatal infections. Univariate and multivariate logistic regressions were used to estimate relative risks by odds ratios with 95% confidence intervals., Results: The caesarean section rate was 39.1% (n = 169). In multivariate regression analysis, the factors associated with caesarean section were the need for oxytocin for labour induction [OR 2.9 (95% CI 1.8-4.5) p < 0.001] and early epidural analgesia [OR 9.9 (95% CI 2.1-47.5), p = 0.004]. The maternal intrapartum infection rate was 6.3%, and the clinical neonatal infection rate was 2.8%. In multivariate analysis, gestational diabetes was associated with maternal intrapartum infection [OR 4.3 (95% CI 1.7-11.0, p = 0.002] and early epidural analgesia with neonatal clinical sepsis [OR 10.5 (95% CI 1.4-76), p = 0.02]., Conclusions: Oxytocin induction and early epidural analgesia were associated with caesarean delivery. Gestational diabetes and early epidural analgesia were associated with infectious morbidity. Since the first caesarean delivery has a major impact on subsequent pregnancies, optimising labour induction among nulliparous women is important.

Objectives: To describe labor outcomes in women with prolonged pregnancy and induction of labor with a Foley catheter, as compared with women with spontaneous onset of labor., Design: Retrospective study., Setting: Helsinki University Hospital., Sample: 553 women with uncomplicated prolonged pregnancies between January 2011 and January 2012, divided into 303 women (54.8%) with Foley catheter induction and 250 (45.2%) with spontaneous labor., Methods: Maternal and neonatal characteristics of women with uncomplicated singleton pregnancy of ≥41(+5) weeks of gestation were analyzed., Main Outcome Measures: Cesarean delivery rates, maternal and neonatal morbidity., Results: The cesarean delivery rate was 30.7% (n = 93/303) in women with labor induction and 4.8% (12/250) in women with spontaneous onset of labor (p < 0.001). The cesarean delivery rate was 37.3% (91/244) among nulliparous women with labor induction and 8.7% (11/126) among women with spontaneous labor, a sixfold increased risk (odds ratio 6.2). Among parous women, cesarean section rates were low and not significantly different (3.4% vs. 0.8%, p = 0.2). There were no differences in maternal intrapartum or postpartum infection rates or adverse neonatal outcomes between the groups., Conclusions: Foley catheter induction of labor in prolonged pregnancy did not increase maternal or perinatal morbidity compared with spontaneous onset of labor but was associated with a considerably increased cesarean section rate, particularly among nulliparous women., (© 2015 Nordic Federation of Societies of Obstetrics and Gynecology.)

The majority of congenital heart defects occur without identifiable risk factors. Detection rates are therefore highly dependent on the experience and expertise of the obstetrical screening operator. In the first trimester, the risk of congenital heart defects increases with increasing nuchal thickness (≥2.5 mm detects 44% of major congenital heart defects), but because of the number of false positives, the positive predictive value is only a few percent. The anatomy of major congenital heart defects may be delineated in less than half of the fetuses during early second trimester. The reported yield of congenital heart defects detection during the mid-gestational routine obstetrical screening has improved over time and detection rates up to 85% of major congenital heart defects have been reported when outflow tract and three-vessel views are included in conjunction with the four-chamber view. Improved detection rates have been achieved following screening operator training interventions combined with a low referral threshold to obtain a detailed fetal echocardiographic study., (© 2014 Nordic Federation of Societies of Obstetrics and Gynecology.)

Aim: Women with a recent induced abortion have a 3-fold risk for suicide, compared to non-pregnant women. The increased risk was recognised in unofficial guidelines (1996) and Current Care Guidelines (2001) on abortion treatment, highlighting the importance of a check-up 2 - 3 weeks after the termination, to monitor for mental health disorders. We studied the suicide trends after induced abortion in 1987 - 2012 in Finland., Methods: We linked the Register on Induced Abortions (N = 284,751) and Cause-of-Death Register (N = 3798 suicides) to identify women who had committed suicide within 1 year after an induced abortion (N = 79). The abortion rates per 100,000 person-years were calculated for 1987 - 1996 (period with no guidelines), 1997 - 2001 (with unofficial guidelines) and 2002 - 2012 (with Current Care Guidelines)., Results: The suicide rate after induced abortion declined by 24%, from 32.4/100,000 in 1987 - 1996 to 24.3/100,000 in 1997 - 2001 and then 24.8/100,000 in 2002 - 2012. The age-adjusted suicide rate among women aged 15 - 49 decreased by 13%; from 11.4/100,000 to 10.4/100,000 and 9.9/100,000, respectively. After induced abortions, the suicide rate increased by 30% among teenagers (to 25/100,000), stagnated for women aged 20 - 24 (at 32/100,000), but decreased by 43% (to 21/100,000) for women aged 25 - 49., Conclusions: The excess risk for suicide after induced abortion decreased, but the change was not statistically significant. Women with a recent induced abortion still have a 2-fold suicide risk. A mandatory check-up may decrease this risk. The causes for the increased suicide risk, including mental health prior to pregnancy and the social circumstances, should be investigated further., (© 2014 the Nordic Societies of Public Health.)

Introduction: Recurrent venous thromboembolism (VTE) during pregnancy is a challenging topic with relatively few publications. The aim of this study was to identify the incidence and the risk factors of recurrent antepartum VTE in women with a history of at least one previous VTE episode., Materials and Methods: This observational cohort study involved 270 pregnant women (369 pregnancies) with at least one previous episode of VTE. The risk factors of recurrent antepartum VTE were identified by using group A (women without recurrent venous thromboembolism VTE) as a control group for group B (women with recurrent VTE despite LMWH (low molecular weight heparin) prophylaxis) and C (women with VTE recurrence in early pregnancy before the planned initiation of LMWH prophylaxis)., Results and Conclusions: The incidence of recurrent VTE was 7.6% (n=28). Twelve recurrent VTEs in ten women (3.3%) developed during early pregnancy before initiation of LMWH and sixteen recurrent VTEs (4.3%) developed in 15 women despite LMWH prophylaxis. In women with recurrent antepartum VTE, the incidence of a history of two or more previous VTEs (group A vs. B: 5.7% vs. 40.0%, p<0.001; group A vs. C: 5.7% vs. 30.0%, p=0.022), previous VTE in connection with antiphospholipid antibody syndrome (group A vs. B: 2.6% vs. 20.0%, p=0.012) and a history of VTE related to hormonal risk factors (group A vs. B: 60.4% vs. 93.3%, p=0.011) was significantly higher compared to those with successful LMWH-prophylaxis. The percentage of the women with long-term anticoagulation was also significantly higher among the women with recurrent antepartum VTE (group A vs. B: 7.6% vs. 46.7%, p<0.001) compared to those with successful LMWH-prophylaxis. The risk of antepartum recurrent VTE is considerable in women with a history of two or more previous VTEs, antiphospholipid antibody syndrome or long-term anticoagulation. The antepartum prophylaxis with prophylactic dose of LMWH or even with intermediate dose of LMWH might not be sufficient in this high-risk population., (Copyright © 2014 Elsevier Ltd.

Objective: The aim of this study was to compare the rate of cesarean sections in 12 delivery units in Finland, and to assess possible associations between cesarean section rates and maternal and neonatal complications., Design: Prospective multicenter cohort study., Setting: The 12 largest delivery units in Finland., Population: Total obstetric population between 1 January 2005 and 30 June 2005 (n = 19 764)., Methods: Prospectively collected data on 2496 cesarean sections and data derived from the Finnish Birth Register on all deliveries in these units were compared. Cesarean section rates and maternal complication rates were adjusted for known risk factors., Main Outcome Measures: Cesarean section rate, maternal complications related to cesarean section, and neonatal asphyxia., Results: The cesarean section rates varied significantly between the hospitals (12.9-25.1%, p < 0.0001), as did the maternal complication rates related to cesarean section (13.0-36.5%, p < 0.0001). There was no relation between maternal complications and the cesarean section rate. The differences remained after adjusting for risk factors. Neonatal asphyxia rates varied between 0.14 and 2.8% (p < 0.0001) and were not related to the cesarean section rates., Conclusions: The rates of cesarean section, maternal complications and neonatal asphyxia vary markedly between different delivery units. Good maternal and neonatal outcomes can be achieved with cesarean section rates <15%., (© 2013 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To study the safety of low-molecular-weight heparin (LMWH) treatment during pregnancy for the mother and the foetus., Study Design: Retrospective controlled cohort study. Six hundred and forty-eight pregnancies exposed to LMWH were compared with 626 unexposed pregnancies. Principal characteristics, indications for LMWH use, and maternal and foetal complications were reported for each pregnancy. Data were obtained from patients' electronic hospital records and analysed using Statistical Package for the Social Sciences Version 17.0., Results: The incidence rates of various pregnancy complications did not differ between the groups (LMWH group vs control group): 1.56% vs 1.1% for thrombocytopenia, 8.7% vs 6.5% for preterm delivery, 0.7% vs 0.3% for stillbirth, 1.4% vs 1.0% for severe pre-eclampsia, 2.7% vs 2.2% for foetal growth restriction, and 10.7% vs 7.8% for antenatal bleeding. One serious antenatal maternal haemorrhage occurred in the LMWH group (0.15%), but this was unrelated to LMWH use. The caesarean section rate and the amount of bleeding during delivery were similar in the two groups (21% vs 19% and 500 vs 450 ml, respectively). The risk of major blood loss during labour (>1000 ml) was no higher in the LMWH group compared with the control group. The incidence of allergic skin reactions was 0.3% in the LMWH group. No heparin-induced thrombocytopenia or symptomatic osteoporotic fractures were observed. Recurrent venous thromboembolic events occurred in 2.5% of patients in the LMWH group., Conclusion: This study indicates that the use of LMWH is safe during pregnancy., (Copyright © 2012 Elsevier Ireland Ltd.

We analyzed the frequency and possible causes of false-negative (Fn) screening results in first-trimester combined Down syndrome screening in Finland. During the study period (May 1, 2002, to December 31, 2008), 76,949 voluntary women with singleton pregnancies participated in screening. Maternal age at screening, week of gestation, levels of pregnancy-associated plasma protein-A (PAPP-A), free β-human chorionic gonadotropin (fβ-hCG), and nuchal translucency (NT) measurement were compared and statistically analyzed between true-positive (Tp) and Fn cases. There were a total of 188 Down syndrome cases (1:409) in the screened population; 154 confirmed Tp and 34 Fn cases. Most Fn cases (n = 25) occurred at 12 + 0 to 13 + 6 weeks' gestation and only nine Fn cases presented between 10 and 11 weeks' gestation. According to the logistic regression analysis, the NT measurement was the most powerful discriminating factor in Fn screening results and accounted for 37.2% of Fn results. The second most important factor was fβ-hCG, adding 14.0% to R(2), followed by PAPP-A, which contributed a further 14.3%. The chosen parameters explain 83.9% of Fn results, but 16.1% remain due to unknown factor(s). All investigated parameters contributed to Fn screening results, but fetal NT was the most discriminating factor leading to an Fn screening result., (Copyright © 2012 by Thieme Medical Publishers, Inc.)

Objective: To evaluate the performance of first-trimester combined screening in 5-year periods according to maternal age in a low-risk population., Design: A prospective study., Setting: Multicenter study in Finland., Population: A total of 76949 voluntary women with singleton pregnancies participated in first-trimester combined screening in public healthcare between 1 May 2002 and 31 December 2008., Methods: The serum samples were analyzed using the PerkinElmer AutoDELFIA® time-resolved fluoroimmunoassay kit for the measurement of pregnancy-associated plasma protein-A and free beta-human chorionic gonadotropin. Nuchal translucency was measured by trained personnel (midwives or physicians) in a university or central hospital., Main Outcome Measures: Performance, detection rate, false positive rate and the number of invasive procedures needed to detect a single case of Down's syndrome were analyzed., Results: There was a direct connection between maternal age and the prevalence of Down's syndrome with a low prevalence in young women being 1:1 193 in the 25-29 age group and 1:150 in the 35-39 age group. Consequently, for a fixed false positive rate of 5%, the number of invasive procedures needed to detect one case of Down's syndrome is higher in younger women to achieve the same detection rate., Conclusions: In combined first trimester screening the risk for Down's syndrome is individual, varying with maternal age. This should be taken into consideration when counseling women., (© 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.)

Recurrent miscarriage affects 1-2% of women. In more than half of all recurrent miscarriage the cause still remains uncertain. Thrombophilia has been identified in about 50% of women with recurrent miscarriage and thromboprophylaxis has been suggested as an option of treatment. A randomised double-blind (for aspirin) multicentre trial was performed among 207 women with three or more consecutive first trimester (<13 weeks) miscarriages, two or more second trimester (13-24 weeks) miscarriages or one third trimester fetal loss combined with one first trimester miscarriage. Women were analysed for thrombophilia. After complete work-up, women were randomly allocated before seven weeks' gestation to either enoxaparin 40 mg and placebo (n=68), enoxaparin 40 mg and aspirin 100 mg (n=63) or aspirin 100 mg (n=76). The primary outcome was live-birth rate. Secondary outcomes were pregnancy complications, neonatal outcome and adverse effects. The trial was ended prematurely because of slow recruitment. A live birth rate of 71% [relative risk (RR) 1.17, 95% confidence interval (CI) 0.92-1.48] was found for enoxaparin and placebo and 65% [RR 1.08, 95% CI 0.83-1.39] for enoxaparin and aspirin when compared to aspirin alone (61%, reference group). In the whole study group the live birth rate was 65% (95% CI 58.66-71.74) for women with three or more miscarriages (n=204). No difference in pregnancy complications, neonatal outcome or adverse effects was observed. No significant difference in live birth rate was found with enoxaparin treatment versus aspirin or a combination of both versus aspirin in women with recurrent miscarriage.

The principal causes of trauma in pregnancy include falls, motor vehicle accidents and violence. Blunt trauma to the abdomen increases the risk of fetomaternal hemorrhage. Massive fetomaternal hemorrhage is a rare but severe complication which can result in fetal anemia, fetal hypoxia, intrauterine death or neonatal neurologic damage. This case report defines incidence and significance of fetomaternal hemorrhage and shows via two cases that even minor maternal injury can lead to severe fetomaternal hemorrhage and risk of fetal compromise. The most common symptoms of fetomaternal hemorrhage are decreased fetal activity and movements reported by the mother. The cornerstones of evaluation of the third trimester trauma patient after abdominal hit are adequate assessment, CTG monitoring and sonographic fetal surveillance.

Objective: To assess the rate of maternal complications related to cesarean section (CS) and to compare morbidity between elective, emergency and crash-emergency CS. To establish risk factors associated with maternal CS morbidity., Design: A prospective multicenter cohort study., Setting: Twelve delivery units in Finland., Population: Women delivering by CS (n = 2,496) during a 6 months period in the study hospitals., Methods: Data on pregnant women, CS, and maternal recovery during the hospital stay was collected prospectively on report forms. The complication rates by different CSs were calculated, and factors associated with morbidity were analyzed by odds ratios (OR)., Main Outcome Measures: Maternal complication rates in different types of CS. The association of risk factors with morbidity., Results: About 27% of women delivering by CS had complications; 10% had severe complications. The complication rate was higher in emergency CS than in elective CS, and highest in crash-emergency CS. Significant independent risk factors for maternal morbidity were emergency CS and crash-emergency CS compared to elective CS (OR 1.8; 95% confidence interval (CI) 1.5-2.2), pre-eclampsia (OR 1.5; CI 1.1-2.0), maternal obesity (OR 1.4; CI 1.1-1.8) and maternal increasing age (OR 1.1; CI 1.03-1.2 per each 5 years)., Conclusions: Maternal complications are frequent in CS, and although performing CS electively reduces the occurrence of complications, the frequency is still high. The complication rate depends on the degree of emergency, and increases with maternal obesity, older age and pre-eclampsia.

The cause of recurrent miscarriage (RM) can be identified in approximately 50% of cases, whereas in others, unknown genetic factors are actively being sought. As mitochondrial functions, and therefore also the mitochondrial genome [mitochondrial DNA (mtDNA)], have an important role in human development, through ATP production and participation in apoptosis, we aimed to study the role of mtDNA variations in RM. We screened 48 women with RM and 48 age-matched control women for heteroplasmic mitochondrial mutations using denaturing high performance liquid chromatography, a sensitive method that can detect approximately 5% heteroplasmy. As a result, we detected a heteroplasmic mtDNA variation in 13 RM women (27%) and in 9 control women (19%). Seven synonymous and five non-synonymous changes were detected within coding regions. In addition, seven heteroplasmic variations were detected within the non-coding control region. We were also able to show the presence of the variations in eight placental samples from three heteroplasmic women. In three of these cases, the proportion of variant mtDNA was higher in the placenta compared with that in the mother. We conclude that our sensitive methodology revealed a higher frequency of samples with heteroplasmic variations than expected in women with both RM and controls. However, no apparent increased frequency of heteroplasmic mtDNA variations or amounts of aberrant mtDNA was detected in the RM group. In addition, none of the detected variations were previously known to be pathogenic and therefore they are an unlikely cause of miscarriage.

This study aimed to investigate the role of p53 in early human development by screening patients with recurrent miscarriages (RM) for mutations in the p53 gene and by studying p53 expression in placental tissue. A total of 46 women with RM and 191 control women were included in the study. A sample was also obtained from 40 male partners of RM patients. The samples were screened for p53 sequence variations using denaturing high-performance liquid chromatography, sequencing and allele-specific polymerase chain reaction. Placental tissue was available from 19 miscarriages. p53 expression in placental tissue was studied by immunohistochemical staining. The C11992A polymorphism in p53 was found to be associated with RM in Finnish patients. The C/A or A/A genotype was detected in 32.6% of the women with RM and in 18.9% of the controls (P = 0.0414, odds ratio 2.083, confidence interval 1.018-4.259). The results suggest that women carrying the C/A or A/A genotype have a two-fold higher risk for RM than women with the C/C genotype. Further studies are, however, necessary to define whether the intronic polymorphism has functional consequences. The immunohistochemical staining of placental tissues revealed no abnormal p53 expression patterns in the samples studied.

Objective: To investigate whether skewed X chromosome inactivation (XCI) and Y chromosome microdeletions are associated with recurrent miscarrige (RM)., Design: A retrospective study., Setting: University hospital and genetic laboratory., Patient(s): Altogether, 46 women with a history of RM, defined as at least three miscarriages, and a control group of 95 women with no history of miscarriage were included in the XCI study. In the Y chromosome microdeletion study 40 male partners of women with RM were studied., Intervention(s): Blood samples for DNA extraction., Main Outcome Measure(s): X chromosome inactivation patterns in the females were analyzed using a methylation-sensitive assay. The DNA from males was tested for Y chromosome microdeletions by analyzing 37 sequence tagged sites., Results: Mildly skewed XCI (>85% inactivation of one allele) was detected in 4 of 43 (9.3%) patients, and 9 of 81 (11.1%) controls. Among these women, extremely skewed XCI (>90% inactivation of one allele) was detected in 2 of 43 (4.7%) patients, and 4 of 81 (4.9%) controls. No statistical differences could be shown between the groups. No microdeletions were found in the male partners., Conclusion(s): The frequency of both extremely and mildly skewed XCI was similar in patients and control women. Y chromosome microdeletions were not found in spouses of patients. Based on these results we conclude that skewed X inactivation and Y chromosome microdeletions are not associated with RM in our study couples.

Context: The incidence of recurrent miscarriage (RM) (>or=3 consecutive pregnancy losses) is estimated as 1-2% in fertile couples. Familial clustering of RM has suggested the contribution of a genetic component., Objective: A low level of human chorionic gonadotropin (HCG) in maternal serum during the first trimester of the pregnancy is a clinically accepted risk factor for miscarriage. We sought to study whether variation in chorionic gonadotropin beta-subunit genes (CGBs) expressed in placenta may contribute to the risk of RM., Design: Resequencing of CGB5 and CGB8, the two most actively transcribed loci of the four HCG beta-duplicate genes, was performed., Setting: A case-control study involving two sample sets, from Estonia (n = 194) and Finland (n = 185), was performed., Patients: RM patients (n = 184) and fertile controls (n = 195) participated in the study., Results: From 71 identified variants in CGB5 and CGB8, 48 polymorphisms were novel. Significant protective effect was associated with two single nucleotide polymorphisms located at identical positions in intron 2 in both CGB5 [P = 0.007; odds ratio (OR) = 0.53] and CGB8 (P = 0.042; OR = 0.15), and with four CGB5 promoter variants (P < 0.03; OR = 0.54-0.58). The carriers of minor alleles had a reduced risk of RM. The haplotype structure of the CGB8 promoter was consistent with balancing selection; a rare mutation in CGB8 initiator element was detected only among patients (n = 3). In addition, three rare nonsynonymous substitutions were identified among RM cases as possible variants increasing the risk of recurrent pregnancy loss., Conclusion: The findings encourage studying the functional effect of the identified variants on CGB expression and HCG hormone activity to elucidate further the role of CGB variation in RM.

Purpose: This study was designed to evaluate prospectively the results of the overlap technique in primary sphincter reconstruction after obstetric tear., Methods: Obstetric tears in 44 women were operated on with primary overlap reconstruction. These women were investigated six to nine months after the operation. Results were compared with those of a historical control group of 52 women whose obstetric sphincter rupture had been treated with the end-to-end technique., Results: The overlap group had significantly more incontinence symptoms after delivery and repair of the sphincter tear than before delivery (P < 0.0001); however, their incontinence symptoms were significantly fewer than those of the end-to-end group (P = 0.004). The prevalence of persistent rupture of the external anal sphincter was significantly lower in the overlap group (6/44, 13.6 percent) than in the end-to-end group (39/52, 75 percent; P < 0.0001). Internal anal sphincter rupture occurred in 5 patients (11.4 percent) in the overlap group and in 40 patients (76.9 percent) in the end-to-end group (P < 0.0001)., Conclusions: The overlap technique should be adopted as the method of choice for primary sphincter repair after obstetric tear.

Background: Recurrent miscarriage (RM) has been suggested to be caused by mutations in genes coding for various coagulation factors resulting in thrombophilia. Mouse models indicate that genes involved in the protein C anticoagulant pathway are essential for normal embryonic development. Loss of function of two of these genes, thrombomodulin (TM) and endothelial protein C receptor (EPCR), causes embryonic lethality in mice. The aim of this study was to determine whether variations in the human TM or EPCR genes are associated with an increased risk for RM., Methods: Forty-six RM patients and 191 controls were screened for mutations in TM and EPCR using denaturing high-performance liquid chromatography (DHPLC). The partners of 40 RM patients were also screened., Results: One exonic and one intronic variation in TM and two exonic and two intronic sequences in EPCR were detected. Four variants were common in both patients and controls. A previously identified truncating mutation in EPCR, suggested to have a role in pregnancy complications, was identified in two patients and one control. A novel deletion in the 3'UTR region of TM was detected, but its significance remains unsolved., Conclusions: These data suggest that mutations in the TM or EPCR genes are not a major cause of RM, although they may exert a modifier effect in combination with other variants.

Introduction: The presence of antiphospholipid (aPL) antibodies increases the risk for recurrent miscarriage (RM). Annexins are a family of structurally related proteins which all bind to anionic phospholipids (PLs) preventing clotting on vascular phospholipid surfaces. The aim of our study was to define plasma concentrations of circulating annexins IV and V at the beginning of pregnancy among women with a history of RM, and in connection to their aPL antibody status., Materials and Methods: Sixty-eight women with RM and 25 controls without history of adverse pregnancy outcome were included in the study. Concentrations of annexins IV and V in plasma were determined by using a sandwich ELISA technique., Results: Hereditary or acquired thrombophilic disorders were found in 53% (36/68) of the patients with RM. Plasma levels of annexin V were significantly higher at the beginning of pregnancy (P=0.03), at the 6th (P=0.01) and 8th week of pregnancy in women with aPL antibodies compared with those without aPL antibodies. A tendency towards higher plasma levels of annexin V was observed in those whose pregnancies ended in miscarriage compared with those with successful pregnancy, although the results did not reach statistical significance (P=0.10). Plasma levels of annexin IV at the first visit in women with aPL antibodies were similar to those at 6 and 8 weeks of gestation. There were no significant differences in plasma annexin IV levels between women with and without aPL antibodies., Conclusions: Patients with RM show elevated plasma levels of annexin V in presence of aPL antibodies. These antibodies could displace annexin from anionic phospholipid surfaces of syncytiotrophoblasts (STBs) and hereby promote coagulation activation.

Thrombin regulation in newborns remains incompletely understood. We studied tissue factor-initiated thrombin formation in cord plasma in vitro, and the effects of Factor V(Leiden) (FVL) heterozygosity on thrombin regulation both in vitro and in vivo in newborns. Pregnant women with known thrombophilia (n=27) were enrolled in the study. Cord blood and venous blood at the age of 14 days were collected from 11 FVL heterozygous newborns (FVL-positive) and from 16 FVL-negative newborns. Prothrombin fragment F1 +2 and coagulation factors were measured. Tissue factor-initiated thrombin formation was studied in cord platelet-poor plasma (PPP) of FVL-negative and -positive newborns, and in both PPP and platelet-rich plasma (PRP) of healthy controls. The endogenous thrombin potential (ETP) in cord PPP or PRP was approximately 60% of that in adult plasma, while thrombin formation started approximately 55% and approximately 40% earlier in cord PPP and PRP, respectively. Further, in FVL-positive newborns thrombin formation started significantly earlier than in FVL-negative newborns. Exogenous activated protein C (APC) decreased ETP significantly more in cord than in adult PRP. In FVL-negative cord plasma 5 nM APC decreased ETP by 17.4+/-3.5% (mean+/-SEM) compared with only 3.5+/-3.8% in FVL-positive cord plasma (p=0.01). FVL-positive newborns showed similar levels of F1 +2 but significantly decreased levels of factorV compared with FVL-negative newborns both in cord plasma (FV 0.82+/-0.07 U/ml vs. 0.98+/- 0.05 U/ml, p=0.03) and at the age of two weeks (FV 1.15+/-0.04 U/ml vs. 1.32+/- 0.05 U/ml, p=0.03). In conclusion, newborn plasma showed more rapid thrombin formation and enhanced sensitivity to APC compared with adult plasma. FVL conveyed APC resistance and a procoagulant effect in newborn plasma. Lack of elevated F1+2 levels in FVL-positive infants, however, suggested the existence of balancing mechanisms; one could be the observed lower level of factor V in FVL heterozygous newborns.

The presence of antiphospholipid antibodies is associated with thromboembolic events, thrombocytopenia and numerous pregnancy complications such as recurrent miscarriage, preeclampsia and HELLP syndrome. This condition is known as the antiphospholipid syndrome (APS). We describe a rare case of recurrent liver necrosis postpartum in two consecutive pregnancies of woman with systemic lupus erythematosus (SLE) and positive antiphospholipid antibodies (aPL) who underwent complete recovery.

Recurrent spontaneous abortions (RSA) are estimated to affect 0.5-1% of couples trying to have a child. The causes of RSA are unknown in the majority of cases. This study aimed to determine whether homozygous mutations in the AMN gene in a fetus cause spontaneous abortions in humans, as they are known to cause spontaneous abortions in mice. The study was conducted by screening 40 couples and 5 women with three or more unexplained spontaneous abortions for heterozygous mutations in the AMN gene using denaturing high-performance liquid chromatography. Altogether, 3 exonic and 11 intronic sequence variations were found. There were no significant differences in the frequencies of the variations between the patients and a control group. One of the exonic variations was non-synonymous, and three of the variations may affect gene splicing. None of the putative phenotype-affecting variations were found in both partners in any couple. These results indicate that RSA in the couples studied cannot be explained by homozygous AMN mutations in the fetus. However, two couples had different, potentially deleterious variations in both partners. If these variations have a phenotypic effect, the RSA experienced by these couples may be caused by mutations in the AMN gene. In addition, birthplaces of the patients' ancestors revealed some clustering, suggesting that some patients may carry a founder mutation in another gene which may contribute to RSA.
