Review
Timing of cortisol collection during pregnancy is an important factor within studies reporting on the association between maternal cortisol and depression during pregnancy. Our objective was to further examine the extent to which reported associations differed across studies according to time of maternal cortisol collection during pregnancy. On December 15, 2016, records were identified using PubMed/MEDLINE (National Library of Medicine), EMBASE (Elsevier; 1974-), Cumulative Index to Nursing and Allied Health Literature (CINAHL, EBSCO), PsycINFO (EBSCO), and Web of Science Core Collection (Thomson Reuters). Unique abstracts were screened using the following inclusion criteria: (1) maternal cortisol assessed during pregnancy; (2) antepartum depression assessed during pregnancy using a screening instrument; (3) reports on the association between maternal cortisol and antepartum depression; (4) provides information on timing of cortisol assessment during pregnancy, including time of day and gestation; and (5) not a review article or a case study. One thousand three hundred seventy-five records were identified, resulting in 826 unique abstracts. Twenty-nine articles met all inclusion criteria. On balance, most studies reported no association between maternal cortisol and antepartum depression (N = 17), and saliva and blood were the most common reported matrices. Morning and second and third trimesters were the most common times of collection during pregnancy. Among studies reporting an association (N = 12), second-trimester and third-trimester cortisol assessments more consistently reported an association and elevated cortisol concentrations were observed in expected recovery periods. Our review adds to the existing literature on the topic, highlighting gaps and strategic next steps.

Review
UNLABELLED
Essentials The evidence on how to manage life-threatening pregnancy-related pulmonary embolism (PE) is scarce. We systematically reviewed all available cases of (sub)massive PE until December 2016. Thrombolysis in such severe PE was associated with a high maternal survival (94%). The major bleeding risk was much greater in the postpartum (58%) than antepartum period (18%).
SUMMARY
Background Massive pulmonary embolism (PE) during pregnancy or the postpartum period is a rare but dramatic event. Our aim was to systematically review the evidence to guide its management. Methods We searched Pubmed, Embase, conference proceedings and the RIETE registry for published cases of severe (submassive/massive) PE treated with thrombolysis, percutaneous or surgical thrombectomy and/or extracorporeal membrane oxygenation (ECMO), occurring during pregnancy or within 6 weeks of delivery. Main outcomes were maternal survival and major bleeding, premature delivery, and fetal survival and bleeding. Results We found 127 cases of severe PE (at least 83% massive; 23% with cardiac arrest) treated with at least one modality. Among 83 women with thrombolysis, survival was 94% (95% CI, 86-98). The risk of major bleeding was 17.5% during pregnancy and 58.3% in the postpartum period, mainly because of severe postpartum hemorrhages. Fetal deaths possibly related to PE or its treatment occurred in 12.0% of cases treated during pregnancy. Among 36 women with surgical thrombectomy, maternal survival and risk of major bleeding were 86.1% (95% CI, 71-95) and 20.0%, with fetal deaths possibly related to surgery in 20.0%. About half of severe postpartum PEs occurred within 24 h of delivery. Conclusions Published cases of thrombolysis for massive PE during pregnancy and the postpartum period suggest a high maternal and fetal survival (94% and 88%). In the postpartum period, given the high risk of major bleeding with thrombolysis, other therapeutic options (catheter [or surgical] thrombectomy, ECMO) may be considered if available.

Meta-Analysis
OBJECTIVE
Women with epilepsy are at risk of pregnancy complications. Whether these vary globally is unknown. We undertook a systematic review to assess the overall rates of obstetric outcomes in women with epilepsy, and variations in estimates across geographical region, economic status of country, and over time.
STUDY DESIGN
We searched Medline, Embase, Cochrane, AMED and CINAHL, (January 1, 1990 and November 29, 2016), without any language restrictions for studies reporting core maternal and fetal outcomes in women with epilepsy. We pooled the results using Freeman-Tukey Transformation random effectsanalysis, and reported our findings as rates of complications per 100 pregnancies with 95% confidence intervals (CI). We assessed for differences in risk across World Health Organisation (WHO) regions, income status, and year of publication.
RESULTS
From the 7420 articles screened, we included 60 studies (62 articles). In women with epilepsy (116,105 pregnancies), the commonest complications were caesarean section (29.2 per 100 pregnancies; 95% CI 25.4-33.1, I=98.44%), and admission to the neonatal intensive care unit (12.5 per 100 pregnancies; 95% CI 9.6-15.8, I=60.63%). There were significant differences across the WHO regions, with the highest rates of caesarean section (37%, 95% CI 32%-42%); spontaneous miscarriage (39%, 95% CI 35%-44%) and preterm birth (10%, 95% CI 8%-12%) in the Americas; postpartum haemorrhage (9%, 95% CI 7%-12%), hypertensive disorders (14%, 95% CI 8%-21%) and perinatal death (2%, 95% CI 1%-7%) in the Western Pacific; induction of labour (30%, 95% CI 19%-41%) in South East Asia and antepartum haemorrhage (10%, 95% CI 5%-17%) in the Eastern Mediterranean. The reported rates of antepartum haemorrhage, caesarean section, gestational diabetes and spontaneous miscarriage were highest in high income and high-middle income countries. Over time, there was a significant increase in caesarean section, and reduction in stillbirths, perinatal deaths and admission to the neonatal intensive care unit in women with epilepsy.
CONCLUSION
There is significant variation in reported maternal and offspring outcomes in pregnant women with epilepsy across geographical regions, economic status of country and over time, which needs to be considered in setting priorities for clinical management and research.

Review
BACKGROUND
We aimed to explore whether maternal asymptomatic hepatitis B (HB) infection effects on pre-term rupture of membranous (PROM), stillbirth, preeclampsia, eclampsia, gestational hypertension, or antepartum hemorrhage.
METHODS
We searched the PubMed, Scopus, and ISI web of science from 1990 to Feb 2015. In addition, electronic literature searches supplemented by searching the gray literature (e.g., conference abstracts thesis and the result of technical reports) and scanning the reference lists of included studies and relevant systematic reviews. We explored statistical heterogeneity using the, I2 and tau-squared (Tau2) statistical tests.
RESULTS
Eighteen studies were included. Preterm rupture of membranous (PROM), stillbirth, preeclampsia, eclampsia, gestational hypertension and antepartum hemorrhage were considerable outcomes in this survey. The results showed no significant association between inactive HB and these complications in pregnancy. The small amounts of -value and chi-square and large amount of I2 suggested the probable heterogeneity in this part, which we tried to modify with statistical methods such as subgroup analysis.
CONCLUSION
Inactive HB infection did not increase the risk of adversely mentioned outcomes in this study. Further, well-designed studies should be performed to confirm the results.

Review
INTRODUCTION
Ogilvie's Syndrome or Acute Colonic Pseudo-Obstruction (ACPO) is a rare condition characterized by massive dilatation of the colon in the absence of mechanical obstruction. About 10% of all reported cases are related to Obstetric and Gynaecological procedures, Caesarean section being the commonest associated factor. Acute intestinal dilatation, if not treated, may lead to perforation and faecal peritonitis with consequent high morbidity and mortality.
MATERIALS AND METHODS
An electronic literature searches were performed in PubMed, EMBASE, Google scholar and hand searches for relevant references were included without any language restriction. All the records reported after year 2002 were included for the full review. We analyzed the quality of the reports and the data was further analyzed for their respective risk factors, clinical features, management methods, morbidity and mortality.
RESULTS
The results from our searches included a total of 125 cases of postpartum ACPO. A total of 66 cases were reported in 37 publications after year 2002. Details of delivery were recorded in 13(19%), clinical manifestations in 49(69%), imaging results in 43(65%) and management described in 100% of the cases. Although 62(92%) cases were following caesarean section, no specific antepartum or intrapartum factors were associated with ACPO. The caesarean sections performed for indications of preeclampsia, multiple pregnancy, antepartum haemorrhage/placenta previa were more in this group of patients who developed ACPO compared to caesarean sections performed for same indication in general population of England and Wales. Abdominal distension and pain were the commonest symptoms, followed by vomiting. Fever was common in patients with perforation. Twenty eight (43%) patients had intestinal perforation or impending perforation, and 31(47%) patients required laparotomy. Conservative management was successful in 33(50%) patients. All patients with a caecal diameter of more than 12cm perforated compared to 3/17 with a diameter of less than 9cm. Most perforations were diagnosed between postoperative day 3 and day 5. Only one case of mortality has been recorded (1.5%).
CONCLUSIONS
No specific risk factors could be identified for postpartum ACPO. A postpartum patient with abdominal distension and pain should have appropriate imaging to rule out colonic dilatation and/or perforation. Perforation may occur with a caecal diameter of less than 9cm but it is more likely if the diameter exceeded 12cm. The mortality risk appears to be low in the postpartum group compared to other patients with ACPO. There is a need for establishing national level databases to capture all the relevant data in a consistent manner, to understand this rare disease process.

Meta-Analysis Review
BACKGROUND
There remains no consensus on the best timing of deinfibulation in women with type III female genital mutilation (FGM).
OBJECTIVES
To conduct a systematic review of the effects of antepartum or intrapartum deinfibulation on childbirth outcomes in women with type III FGM.
SEARCH STRATEGY
The following major databases were searched: Cochrane Central Register for Controlled Trials (CENTRAL), MEDLINE, Scopus, Web of Science, and ClinicalTrials.gov, from inception until August 2015 without any language restrictions.
SELECTION CRITERIA
Studies of pregnant women or girls with type III FGM who were deinfibulated antepartum or intrapartum were included.
DATA COLLECTION AND ANALYSIS
Two team members independently screened and collected data. Quality of evidence was assessed using GRADE. Summary odds ratios and proportions were calculated when possible.
RESULTS
There is no evidence of a significant difference between antepartum and intrapartum deinfibulation for obstetric outcomes such as duration of labor, perineal lacerations, episiotomies, postpartum hemorrhage, and cesarean deliveries. Outcomes in women living with type III FGM and those who have undergone deinfibulation were not statistically different; however, trends show a benefit for deinfibulation. All studies were underpowered to detect statistical differences.
CONCLUSION
Larger studies are required to have full confidence in these findings.

Meta-Analysis Review
Antepartum hemorrhage (APH) is an important cause of perinatal mortality and maternal morbidity in pregnant women with placenta previa in the world. However, the epidemiological characteristics are not completely understood. We performed an initial systematic review and meta-analysis to assess the prevalence of APH in pregnant women with placenta previa. It was totally performed following the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement. PubMed, Elsevier Science Direct, and the Cochrane Library were searched before April 2016. A meta-analysis with a random-effects model based on a proportions approach was performed to determine the prevalence. Stratified analyses, meta-regression method, and sensitivity analysis were utilized to analyze the heterogeneity. A total of 29 articles were included. The pooled overall prevalence of APH among pregnant women with placenta previa was 51.6% (95% CI 42.7-60.6) in a heterogeneous set of studies (I = 97.9). Correlation analysis found that there was a positive correlation between prevalence and percentage of multiparous (r = 0.534, P = 0.027) and a negative correlation between prevalence and survey year (r = -0.400, P = 0.031). In conclusion, the prevalence of APH was a high condition among pregnant women with placenta previa.

Meta-Analysis Review
We performed a meta-analysis to evaluate the risk of venous thromboembolism (VTE) in pregnant women with essential thrombocythemia. Twenty-one trials and 756 pregnancies met inclusion criteria. The absolute VTE risk in the antepartum period is not above a threshold where low-molecular-weight heparin (LMWH) prophylaxis is clearly indicated or below a threshold where LMWH should be withheld (2.5%; 95% CI, 1.3-4.3). Postpartum, the absolute VTE risk is above a threshold where postpartum LMWH prophylaxis should be considered (4.4%; 95% CI, 1.2-9.5).

Meta-Analysis Review
BACKGROUND
Bipolar Disorder (BD) is a mental disorder usually diagnosed between 18 and 30 years of age; this coincides with the period when many women experience pregnancy and childbirth. As specific problems have been reported in pregnancy and childbirth when the mother has BD, a systematic review was carried out to summarise the outcomes of pregnancy and childbirth, in mother and child, when the mother has BD diagnosed before pregnancy.
METHODS
An a priori protocol was designed and a systematic search conducted in PubMed, CINAHL, Scopus, PsycINFO and Cochrane databases in March 2015. Studies of all designs were included if they involved women with a diagnosis of bipolar disorder prior to pregnancy, who were pregnant and/or followed up to one year postpartum. All stages of inclusion, quality assessment and data extraction were done by two people. All maternal or infant outcomes were examined, and narrative synthesis was used for most outcomes. Meta-analysis was used to achieve a combined prevalence for some outcomes and, where possible, case and control groups were combined and compared.
RESULTS
The search identified 2809 papers. After screening and quality assessement (using the EPHPP and AMSTAR tools), nine papers were included. Adverse pregnancy outcomes such as gestational hypertension and antepartum haemorrhage occur more frequently in women with BD. They also have increased rates of induction of labour and caesarean section, and have an increased risk of mood disorders in the postnatal period. Women with BD are more likely to have babies that are severely small for gestational age (<2nd-3rd percentile), and it appears that those women not being treated with mood stabilisers in pregnancy might not have an increased risk of having a baby with congenital abnormalities.
DISCUSSION
Due to heterogeneity of data, particularly the use of differing definitions of bipolar disorder, narrative synthesis was used for most outcomes, rather than a meta-analysis.
CONCLUSIONS
It is evident that adverse outcomes are more common in women with BD and their babies. Large cohort studies examining fetal abnormality outcomes for women with BD who are not on mood stabilisers in pregnancy are required, as are studies on maternal-infant interaction.

Meta-Analysis Review
BACKGROUND
Midwives are primary providers of care for childbearing women around the world. However, there is a lack of synthesised information to establish whether there are differences in morbidity and mortality, effectiveness and psychosocial outcomes between midwife-led continuity models and other models of care.
OBJECTIVES
To compare midwife-led continuity models of care with other models of care for childbearing women and their infants.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (25 January 2016) and reference lists of retrieved studies.
SELECTION CRITERIA
All published and unpublished trials in which pregnant women are randomly allocated to midwife-led continuity models of care or other models of care during pregnancy and birth.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach.
MAIN RESULTS
We included 15 trials involving 17,674 women. We assessed the quality of the trial evidence for all primary outcomes (i.e. regional analgesia (epidural/spinal), caesarean birth, instrumental vaginal birth (forceps/vacuum), spontaneous vaginal birth, intact perineum, preterm birth (less than 37 weeks) and all fetal loss before and after 24 weeks plus neonatal death using the GRADE methodology: all primary outcomes were graded as of high quality.For the primary outcomes, women who had midwife-led continuity models of care were less likely to experience regional analgesia (average risk ratio (RR) 0.85, 95% confidence interval (CI) 0.78 to 0.92; participants = 17,674; studies = 14; high quality), instrumental vaginal birth (average RR 0.90, 95% CI 0.83 to 0.97; participants = 17,501; studies = 13; high quality), preterm birth less than 37 weeks (average RR 0.76, 95% CI 0.64 to 0.91; participants = 13,238; studies = eight; high quality) and less all fetal loss before and after 24 weeks plus neonatal death (average RR 0.84, 95% CI 0.71 to 0.99; participants = 17,561; studies = 13; high quality evidence). Women who had midwife-led continuity models of care were more likely to experience spontaneous vaginal birth (average RR 1.05, 95% CI 1.03 to 1.07; participants = 16,687; studies = 12; high quality). There were no differences between groups for caesarean births or intact perineum.For the secondary outcomes, women who had midwife-led continuity models of care were less likely to experience amniotomy (average RR 0.80, 95% CI 0.66 to 0.98; participants = 3253; studies = four), episiotomy (average RR 0.84, 95% CI 0.77 to 0.92; participants = 17,674; studies = 14) and fetal loss less than 24 weeks and neonatal death (average RR 0.81, 95% CI 0.67 to 0.98; participants = 15,645; studies = 11). Women who had midwife-led continuity models of care were more likely to experience no intrapartum analgesia/anaesthesia (average RR 1.21, 95% CI 1.06 to 1.37; participants = 10,499; studies = seven), have a longer mean length of labour (hours) (mean difference (MD) 0.50, 95% CI 0.27 to 0.74; participants = 3328; studies = three) and more likely to be attended at birth by a known midwife (average RR 7.04, 95% CI 4.48 to 11.08; participants = 6917; studies = seven). There were no differences between groups for fetal loss equal to/after 24 weeks and neonatal death, induction of labour, antenatal hospitalisation, antepartum haemorrhage, augmentation/artificial oxytocin during labour, opiate analgesia, perineal laceration requiring suturing, postpartum haemorrhage, breastfeeding initiation, low birthweight infant, five-minute Apgar score less than or equal to seven, neonatal convulsions, admission of infant to special care or neonatal intensive care unit(s) or in mean length of neonatal hospital stay (days).Due to a lack of consistency in measuring women's satisfaction and assessing the cost of various maternity models, these outcomes were reported narratively. The majority of included studies reported a higher rate of maternal satisfaction in midwife-led continuity models of care. Similarly, there was a trend towards a cost-saving effect for midwife-led continuity care compared to other care models.
AUTHORS' CONCLUSIONS
This review suggests that women who received midwife-led continuity models of care were less likely to experience intervention and more likely to be satisfied with their care with at least comparable adverse outcomes for women or their infants than women who received other models of care.Further research is needed to explore findings of fewer preterm births and fewer fetal deaths less than 24 weeks, and all fetal loss/neonatal death associated with midwife-led continuity models of care.
