Meta-Analysis
OBJECTIVE
This systematic review and meta-analysis aimed to evaluate the performance of existing externally validated prediction models for pre-eclampsia (PE) (specifically, any-onset, early-onset, late-onset and preterm PE).
METHODS
A systematic search was conducted in five databases (MEDLINE, EMBASE, Emcare, CINAHL and Maternity & Infant Care Database) and using Google Scholar/reference search to identify studies based on the Population, Index prediction model, Comparator, Outcome, Timing and Setting (PICOTS) approach until 20 May 2023. We extracted data using the CHARMS checklist and appraised the risk of bias using the PROBAST tool. A meta-analysis of discrimination and calibration performance was conducted when appropriate.
RESULTS
Twenty-three studies reported 52 externally validated prediction models for PE (one preterm, 20 any-onset, 17 early-onset and 14 late-onset PE models). No model had the same set of predictors. Fifteen any-onset PE models were validated externally once, two were validated twice and three were validated three times, while the Fetal Medicine Foundation (FMF) competing-risks model for preterm PE prediction was validated widely in 16 different settings. The most common predictors were maternal characteristics (prepregnancy body mass index, prior PE, family history of PE, chronic medical conditions and ethnicity) and biomarkers (uterine artery pulsatility index and pregnancy-associated plasma protein-A). The FMF model for preterm PE (triple test plus maternal factors) had the best performance, with a pooled area under the receiver-operating-characteristics curve (AUC) of 0.90 (95% prediction interval (PI), 0.76-0.96), and was well calibrated. The other models generally had poor-to-good discrimination performance (median AUC, 0.66 (range, 0.53-0.77)) and were overfitted on external validation. Apart from the FMF model, only two models that were validated multiple times for any-onset PE prediction, which were based on maternal characteristics only, produced reasonable pooled AUCs of 0.71 (95% PI, 0.66-0.76) and 0.73 (95% PI, 0.55-0.86).
CONCLUSIONS
Existing externally validated prediction models for any-, early- and late-onset PE have limited discrimination and calibration performance, and include inconsistent input variables. The triple-test FMF model had outstanding discrimination performance in predicting preterm PE in numerous settings, but the inclusion of specialized biomarkers may limit feasibility and implementation outside of high-resource settings. © 2023 The Authors.

Meta-Analysis
OBJECTIVE
Pre-eclampsia (PE) is a serious pregnancy status characterized by high blood pressure. Although visfatin is usually associated with PE. Observational studies evaluating the relationship between circulating visfatin and pre-eclampsia have reported inconsistent results. We conducted this systematic review and meta-analysis to summarize published data on the association between visfatin and pre-eclampsia.
METHODS
Electronic databases PubMed, ISI web of science, EMBASE, Scopus and the Cochrane library were comprehensively searched for selection of eligible studies until January 5, 2020. A random-effects model and the generic inverse variance method were used for quantitative data synthesis. The assessment of study quality was performed using the e Newcastle-Ottawa scale and the Agency for Healthcare Research and Quality. Sensitivity analyses and prespecified subgroup were conducted to evaluate potential heterogeneity. Random-effects meta-regression was conducted to assess the impact of potential confounders on the estimated effect sizes. The protocol for this study was registered in PROSPERO (No. CRD42018105861) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
RESULTS
Thirteen studies comprising a total of 536 subjects were included in this meta-analysis. We observed that the pre-eclampsia risk is associated with a statistically significant elevation of visfatin level [SMD (1.33 µg/l) (95% CI 0.37, 2.2) = .007]. No significant publication bias was observed in the meta-analysis. Subgroup and sensitivity analyses indicated that the pooled effects size were affected by systolic blood pressure [SMD (1.82 µg/l) 95% CI (0.94, 2.7), < .05], gestational age [SMD (2.01 µg/l) 95% CI (0.57, 3.4), = .006], body mass index [SMD (1.6 µg/l) 95% CI (0.37, 3), < .05] and pregnancy trimesters[SMD (2.3 µg/l) 95% CI (0.95, 3.7), = .001]. Random-effects meta-regression showed a significant association of visfatin level with potential confounders including systolic blood pressure, gestational age and birth weight at delivery of pre-eclampsia patients.
CONCLUSIONS
Collectively, our data revealed that the increase of visfatin level can be associated with the risk of pre-eclampsia. However, further studies on pre-eclampsia populations are warranted for corroboration of our findings.

International Journal of Gynaecology... Apr 2023Evidence has shown significant benefits of aspirin for preventing pre-eclampsia. (Review)
Review
BACKGROUND
Evidence has shown significant benefits of aspirin for preventing pre-eclampsia.
OBJECTIVES
The objective of this study was to systematically review recommendations from clinical practice guidelines and other recommendation documents on aspirin for the prevention of pre-eclampsia.
SEARCH STRATEGY
Ten databases were searched for statements from December 1, 2013, to January 1, 2022.
SELECTION CRITERIA
Without language restrictions, the most recent version of documents was considered.
DATA COLLECTION AND ANALYSIS
Two authors independently extracted recommendations. Guideline quality was assessed using a modified AGREE-II instrument and the AGREE-REX tool.
MAIN RESULTS
Out of 48 statements on the prevention of pre-eclampsia, 46 had recommendations on use of aspirin. Of them, 39 were supported by evidence from systematic reviews or randomized controlled trials. Three statements reported aspirin's significant reductions in preterm pre-eclampsia and one in perinatal death. Concerning quality, 41% of statements were rated as high quality in all domains of the AGREE-II tool, 15% were rated high quality in all domains of the AGREE-REX tool, and 11% were rated high quality in all domains on both tools.
CONCLUSIONS
While 96% of statements advocated for use of aspirin, only 9% reported a significant reduction in preterm pre-eclampsia or perinatal death. Based on the AGREE tools, future statements could use methodological improvement.

Review
INTRODUCTION
Mirror syndrome is a rare disease associated with high fetal mortality of up to 67.2%. It is thought to be underdiagnosed and is often associated with preeclampsia. Mirror syndrome is characterized by "triple edema": generalized maternal, placental, and fetal edema.
OBJECTIVE
This comprehensive review aims to thoroughly summarize the existing data and provide a broad update on the topic to help accurate diagnosis and encourage further research.
METHODS
A comprehensive search of several databases (Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus) was conducted.
RESULTS
The last systematic review of mirror syndrome cases was conducted in 2016 and included 113 patients. Much is still unknown about the pathophysiology of the disease and it remains underdiagnosed.
CONCLUSIONS AND RELEVANCE
Mirror syndrome is likely more prevalent than current data suggests for it is often misdiagnosed as pre-eclampsia. The differential of Mirror syndrome should be considered in anomalous presentations of pre-eclampsia as intervention may save the fetus and improve maternal symptoms. It is important to further the study on the pathophysiology of the disease to better understand, diagnose and potentially treat it, to avoid its high morbidity and mortality.

Meta-Analysis
BACKGROUND
There is widespread, increasing use of magnesium sulphate in obstetric practice for pre-eclampsia, eclampsia, and preterm fetal neuroprotection; benefit for preventing preterm labour and birth (tocolysis) is unproven. We conducted a systematic review and meta-analysis to assess whether antenatal magnesium sulphate is associated with unintended adverse neonatal outcomes.
METHODS AND FINDINGS
CINAHL, Cochrane Library, LILACS, MEDLINE, Embase, TOXLINE, and Web of Science, were searched (inceptions to 3 September 2019). Randomised, quasi-randomised, and non-randomised trials, cohort and case-control studies, and case reports assessing antenatal magnesium sulphate for pre-eclampsia, eclampsia, fetal neuroprotection, or tocolysis, compared with placebo/no treatment or a different magnesium sulphate regimen, were included. The primary outcome was perinatal death. Secondary outcomes included pre-specified and non-pre-specified adverse neonatal outcomes. Two reviewers screened 5,890 articles, extracted data, and assessed risk of bias following Cochrane Handbook and RTI Item Bank guidance. For randomised trials, pooled risk ratios (RRs) or mean differences, with 95% confidence intervals (CIs), were calculated using fixed- or random-effects meta-analysis. Non-randomised data were tabulated and narratively summarised. We included 197 studies (40 randomised trials, 138 non-randomised studies, and 19 case reports), of mixed quality. The 40 trials (randomising 19,265 women and their babies) were conducted from 1987 to 2018 across high- (16 trials) and low/middle-income countries (23 trials) (1 mixed). Indications included pre-eclampsia/eclampsia (24 trials), fetal neuroprotection (7 trials), and tocolysis (9 trials); 18 trials compared magnesium sulphate with placebo/no treatment, and 22 compared different regimens. For perinatal death, no clear difference in randomised trials was observed between magnesium sulphate and placebo/no treatment (RR 1.01; 95% CI 0.92 to 1.10; 8 trials, 13,654 babies), nor between regimens. Eleven of 138 non-randomised studies reported on perinatal death. Only 1 cohort (127 babies; moderate to high risk of bias) observed an increased risk of perinatal death with >48 versus ≤48 grams magnesium sulphate exposure for tocolysis. No clear secondary adverse neonatal outcomes were observed in randomised trials, and a very limited number of possible adverse outcomes warranting further consideration were identified in non-randomised studies. Where non-randomised studies observed possible harms, often no or few confounders were controlled for (moderate to high risk of bias), samples were small (200 babies or fewer), and/or results were from subgroup analyses. Limitations include missing data for important outcomes across most studies, heterogeneity of included studies, and inclusion of published data only.
CONCLUSIONS
Our findings do not support clear associations between antenatal magnesium sulphate for beneficial indications and adverse neonatal outcomes. Further large, high-quality studies (prospective cohorts or individual participant data meta-analyses) assessing specific outcomes, or the impact of regimen, pregnancy, or birth characteristics on these outcomes, would further inform safety recommendations.

Pituitary Jun 2022To evaluate the association between acromegaly and pregnancy in terms of disease activity, maternal and fetal outcomes. (Meta-Analysis)
Meta-Analysis
PURPOSE
To evaluate the association between acromegaly and pregnancy in terms of disease activity, maternal and fetal outcomes.
METHODS
This systematic review was conducted according to the Joanna Briggs Institute methodology for systematic reviews of etiology and risk. We focused on observational studies that included pregnant women with acromegaly. The outcomes were acromegaly activity, preterm birth, gestational diabetes, hypertension, eclampsia/preeclampsia, miscarriage, perinatal mortality, low birthweight, small for gestational age, and congenital malformations. Embase, Medline, LILACS, and CENTRAL were our source databases. To perform proportional meta-analyses, we used Stata Statistical Software 17.
RESULTS
Nineteen studies were included encompassing a total of 273 pregnancies in 211 women with acromegaly. The overall frequency of control of acromegaly during pregnancy was 62%, and of tumor growth was 9%. No fetal or maternal deaths were reported. The overall frequency of worsening of previous diabetes or development of gestational diabetes was 9%, and of previous hypertension or preeclampsia/eclampsia was 6%. The overall frequency of premature labor was 9% [from 17 studies of 263 pregnancies; 95% confidence interval (CI), 5-13%]; of spontaneous miscarriage was 4% (from 19 studies of 273 pregnancies; 95% CI, 2-11%); of small for gestational age was 5% (from 15 studies of 216 newborns; 95% CI, 3-9%); and of congenital malformations was 1% (from 18 studies of 240 newborns; 95% CI, 0-7%).
CONCLUSION
Pregnancy in women with acromegaly is frequently associated with disease control and is safe in relation to fetal and maternal outcomes, as in women without acromegaly.

Review
BACKGROUND
This systematic review and meta-analysis summarizes the evidence for the association between endometriosis and adverse pregnancy outcome, including gestational hypertension, pre-eclampsia, low birth weight, and small for gestational age, preterm birth, placenta previa, placental abruption, cesarean section, stillbirth, postpartum hemorrhage, spontaneous hemoperitoneum in pregnancy, and spontaneous bowel perforation in pregnancy.
METHODS
We performed the literature review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), by searches in PubMed and EMBASE, until 1 November 2020 (PROSPERO ID CRD42020213999). We included peer-reviewed observational cohort studies and case-control studies and scored them according to the Newcastle-Ottawa Scale, to assess the risk of bias and confounding.
RESULTS
39 studies were included. Women with endometriosis had an increased risk of gestational hypertension, pre-eclampsia, preterm birth, placenta previa, placental abruption, cesarean section, and stillbirth, compared to women without endometriosis. These results remained unchanged in sub-analyses, including studies on spontaneous pregnancies only. Spontaneous hemoperitoneum in pregnancy and bowel perforation seemed to be associated with endometriosis; however, the studies were few and did not meet the inclusion criteria.
CONCLUSIONS
The literature shows that endometriosis is associated with an increased risk of gestational hypertension, pre-eclampsia, preterm birth, placenta previa, placental abruption, cesarean section, and stillbirth.

Meta-Analysis
BACKGROUND
Aspirin and heparin are widely used as preventive strategy to reduce the high risk of recurrent pregnancy loss in women with antiphospholipid antibodies (aPL). This review supersedes a previous, out-of-date review that evaluated all potential therapies for preventing recurrent pregnancy loss in women with aPL. The current review focusses on a narrower scope because current clinical practice is restricted to using aspirin or heparins, or both for women with aPL in an attempt to reduce pregnancy complications.
OBJECTIVES
To assess the effects of aspirin or heparin, or both for improving pregnancy outcomes in women with persistent (on two separate occasions) aPL, either lupus anticoagulant (LAC), anticardiolipin (aCL) or aβ-glycoprotein-I antibodies (aβGPI) or a combination, and recurrent pregnancy loss (two or more, which do not have to be consecutive).
SEARCH METHODS
We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (3 June 2019), and reference lists of retrieved studies. Where necessary, we attempted to contact trial authors.
SELECTION CRITERIA
Randomised, cluster-randomised and quasi-randomised controlled trials that assess the effects of aspirin, heparin (either low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH]), or a combination of aspirin and heparin compared with no treatment, placebo or another, on pregnancy outcomes in women with persistent aPL and recurrent pregnancy loss were eligible. All treatment regimens were considered.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion criteria and risk of bias. Two review authors independently extracted data and checked them for accuracy and the certainty of the evidence was assessed using the GRADE approach.
MAIN RESULTS
Eleven studies (1672 women) met the inclusion criteria; nine randomised controlled trials and two quasi-RCTs. The studies were conducted in the USA, Canada, UK, China, New Zealand, Iraq and Egypt. One included trial involved 1015 women, all other included trials had considerably lower numbers of participants (i.e. 141 women or fewer). Some studies had high risk of selection and attrition bias, and many did not include sufficient information to judge the risk of reporting bias. Overall, the certainty of evidence is low to very low due to the small numbers of women in the studies and to the risk of bias. The dose and type of heparin and aspirin varied among studies. One study compared aspirin alone with placebo; no studies compared heparin alone with placebo and there were no trials that had a no treatment comparator arm during pregnancy; five studies explored the efficacy of heparin (either UFH or LMWH) combined with aspirin compared with aspirin alone; one trial compared LMWH with aspirin; two trials compared the combination of LMWH plus aspirin with the combination of UFH plus aspirin; two studies evaluated the combination of different doses of heparin combined with aspirin. All trials used aspirin at a low dose. Aspirin versus placebo We are very uncertain if aspirin has any effect on live birth compared to placebo (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.71 to 1.25, 1 trial, 40 women, very low-certainty evidence). We are very uncertain if aspirin has any effect on the risk of pre-eclampsia, pregnancy loss, preterm delivery of a live infant, intrauterine growth restriction or adverse events in the child, compared to placebo. We are very uncertain if aspirin has any effect on adverse events (bleeding) in the mother compared with placebo (RR 1.29, 95% CI 0.60 to 2.77, 1 study, 40 women). The certainty of evidence for these outcomes is very low because of imprecision, due to the low numbers of women involved and the wide 95% CIs, and also because of risk of bias. Venous thromboembolism and arterial thromboembolism were not reported in the included studies. Heparin plus aspirin versus aspirin alone Heparin plus aspirin may increase the number of live births (RR 1.27, 95% CI 1.09 to 1.49, 5 studies, 1295 women, low-certainty evidence). We are uncertain if heparin plus aspirin has any effect on the risk of pre-eclampsia, preterm delivery of a live infant, or intrauterine growth restriction, compared with aspirin alone because of risk of bias and imprecision due to the low numbers of women involved and the wide 95% CIs. We are very uncertain if heparin plus aspirin has any effect on adverse events (bleeding) in the mother compared with aspirin alone (RR 1.65, 95% CI 0.19 to 14.03, 1 study, 31 women). No women in either the heparin plus aspirin group or the aspirin alone group had heparin-induced thrombocytopenia, allergic reactions, or venous or arterial thromboembolism. Similarly, no infants had congenital malformations. Heparin plus aspirin may reduce the risk of pregnancy loss (RR 0.48, 95% CI 0.32 to 0.71, 5 studies, 1295 women, low-certainty evidence). When comparing LMWH plus aspirin versus aspirin alone the pooled RR for live birth was 1.20 (95% CI 1.04 to 1.38, 3 trials, 1155 women). In the comparison of UFH plus aspirin versus aspirin alone, the RR for live birth was 1.74 (95% CI 1.28 to 2.35, 2 trials, 140 women).
AUTHORS' CONCLUSIONS
The combination of heparin (UFH or LMWH) plus aspirin during the course of pregnancy may increase live birth rate in women with persistent aPL when compared with aspirin treatment alone. The observed beneficial effect of heparin was driven by one large study in which LMWH plus aspirin was compared with aspirin alone. Adverse events were frequently not, or not uniformly, reported in the included studies. More research is needed in this area in order to further evaluate potential risks and benefits of this treatment strategy, especially among women with aPL and recurrent pregnancy loss, to gain consensus on the ideal prevention for recurrent pregnancy loss, based on a risk profile.

Multiple Sclerosis and Related Disorders Jul 2023Aquaporin-4 antibody positive (AQP4+) neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are rare... (Review)
Review
A systematic literature review to examine the considerations around pregnancy in women of child-bearing age with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) or aquaporin 4 neuromyelitis optica spectrum disorder (AQP4+ NMOSD).
BACKGROUND
Aquaporin-4 antibody positive (AQP4+) neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are rare autoimmune diseases with overlapping phenotypes. Understanding their clinical manifestation prior to, during and after pregnancy may influence the management of women of child-bearing age (WOCBA) with these diseases.
METHODS
This systematic review identified relevant MEDLINE-indexed publications dated between 01 January 2011 and 01 November 2021, and congress materials from key conferences between 01 January 2019 and 01 November 2021. These were manually assessed for relevance to AQP4+ NMOSD and/or MOGAD in WOCBA, with selected data extracted and considered.
RESULTS
In total, 107 articles were retrieved and reviewed for relevancy, including 65 clinical studies. Limited evidence was found regarding a conclusive impact of either disease on female fertility, sexual function or menarche, and impact on maternal outcomes requires further investigation in both conditions to establish risk for pre-eclampsia, gestational diabetes and other complications relative to the general population. Collated data for pregnancy outcomes show clear risks in AQP4+ NMOSD to healthy delivery and a rise in annualised relapse rate postpartum that may require adaptation of treatment regimens. Disease activity appears to be attenuated during pregnancy in MOGAD patients with an increased risk of relapse during the postpartum months, but strong conclusions cannot be made due to a paucity of available data.
CONCLUSIONS
This review brings together the literature on AQP4+ NMOSD and MOGAD in WOCBA. The potential impact of pregnancy and the postpartum period on disease activity suggest a proactive management strategy early on may improve maternal and infant outcomes, but more clinical data are needed, particularly for MOGAD.

European Heart Journal. Quality of Care... Jan 2024There is a need for further studies on the cardiovascular risk of women experiencing pre-eclampsia (PE). (Meta-Analysis)
Meta-Analysis
BACKGROUND/INTRODUCTION
There is a need for further studies on the cardiovascular risk of women experiencing pre-eclampsia (PE).
PURPOSE
To update the literature regarding the association between a history of PE and subsequent cardiovascular diseases, including cardiovascular death, coronary heart diseases, heart failure, and stroke, focusing on the trend in the effect size (ES) estimates over time.
METHODS AND RESULTS
Following PRISMA guidelines, from inception to May 2023, we performed a systematic review of PubMed, MEDLINE, Scopus, and EMBASE. Randomized, cohort, or case-control studies in English were included if fulfiling the following criteria:(i) The association between PE and subsequent cardiovascular disease was adjusted for clinically relevant variables, (ii) the presence of a control group, and (iii) at least 1 year of follow-up. Pooled adjusted ESs and 95% confidence intervals (CIs) were used as effect estimates and calculated with a random-effect model. Twenty-two studies met the inclusion criteria. PE was associated with a higher risk of cardiovascular death (ES 2.08, 95% CI 1.70-2.54, I2 56%, P < 0.00001), coronary artery diseases (ES 2.04, 95% CI 1.76-2.38, I2 87%, P < 0.00001), heart failure (ES 2.47, 95% CI 1.89-3.22, I2 83%, P < 0.00001), and stroke (ES 1.75, 95% CI 1.52-2.02, I2 72%, P < 0.00001) after adjusting for potential confounders. This risk is evident in the first 1-to-3 years of follow-up and remains significant until 39 years of follow-up.
CONCLUSIONS
Compared to women who experienced a normal pregnancy, those suffering from PE have about double the risk of lifetime cardiovascular disease.
