UNASSIGNED: Isolated fetal ventriculomegaly can have a range of consequences, ranging from mild neurodevelopmental delay to perinatal death; the extent of these consequences often depend on the severity of ventriculomegaly. This systematic review and meta-analysis aims to investigate the impact of the degree of ventricular dilatation on the risk of neurodevelopmental delay and adverse perinatal outcomes in fetuses diagnosed with isolated fetal ventriculomegaly from gestational week 15 onwards.
UNASSIGNED: PubMed, Embase, Scopus and the Cochrane Library were searched electronically to identify studies investigating the prognosis of mild and/or severe isolated fetal ventriculomegaly. Articles were included if they reported neurodevelopmental or perinatal outcomes in fetuses prenatally diagnosed with isolated fetal ventriculomegaly from week 15 of gestation and onwards. Studies were excluded if they reported on non-isolated ventriculomegaly (IVM), failed to specify the degree of ventriculomegaly, were non-English papers, animal studies or published outside of the 21-year period of interest. Study quality was assessed by two independent reviewers using a modified version of the Newcastle-Ottawa Quality Assessment Scale. Ventriculomegaly was defined as either mild or severe when ventricular diameter measured as 10-15 or >15 mm, respectively. Meta-analyses were conducted for adverse neurodevelopmental outcome, intrauterine fetal demise and infant mortality.
UNASSIGNED: Following the removal of duplicates, the search yielded 2,452 citations, of which 23 studies were included and 8 were eligible for meta-analysis. There were 767 and 347 cases of mild and severe isolated fetal ventriculomegaly, respectively. Adverse outcomes were consistently reported at a higher rate in severe cases than mild. The relative risks of adverse neurodevelopmental outcome, intrauterine fetal demise and infant mortality were 4.24 [95% confidence interval (CI): 2.46-7.30], 4.46 (95% CI: 1.64-12.11) and 6.02 (95% CI: 1.73-21.00), respectively, upon comparison of mild versus severe cases of isolated fetal ventriculomegaly.
UNASSIGNED: The likelihood of adverse neurodevelopmental and perinatal outcomes, including intrauterine and infant mortality, is increased in severe isolated fetal ventriculomegaly compared to mild isolated fetal ventriculomegaly.

OBJECTIVE: To assess the diagnostic accuracy of ultrasound for detecting placenta accreta spectrum (PAS) during the first trimester of pregnancy and compare it with the accuracy of second- and third-trimester ultrasound examination in pregnancies at risk for PAS.
METHODS: PubMed, EMBASE and Web of Science databases were searched to identify relevant studies published from inception until 10 March 2023. Inclusion criteria were cohort, case-control or cross-sectional studies that evaluated the accuracy of ultrasound examination performed at < 14 weeks of gestation (first trimester) or ≥ 14 weeks of gestation (second/third trimester) for the diagnosis of PAS in pregnancies with clinical risk factors. The primary outcome was the diagnostic accuracy of sonography in detecting PAS in the first trimester, compared with the accuracy of ultrasound examination in the second and third trimesters. The secondary outcome was the diagnostic accuracy of each sonographic marker individually across the trimesters of pregnancy. The reference standard was PAS confirmed at pathological or surgical examination. The potential of ultrasound and different ultrasound signs to detect PAS was assessed by computing summary estimates of sensitivity, specificity, diagnostic odds ratio and positive and negative likelihood ratios.
RESULTS: A total of 37 studies, including 5764 pregnancies at risk of PAS, with 1348 cases of confirmed PAS, were included in our analysis. The meta-analysis demonstrated that ultrasound had a sensitivity of 86% (95% CI, 78-92%) and specificity of 63% (95% CI, 55-70%) during the first trimester, and a sensitivity of 88% (95% CI, 84-91%) and specificity of 92% (95% CI, 85-96%) during the second/third trimester. Regarding sonographic markers examined in the first trimester, lower uterine hypervascularity exhibited the highest sensitivity (97% (95% CI, 19-100%)), and uterovesical interface irregularity demonstrated the highest specificity (99% (95% CI, 96-100%)). In the second/third trimester, loss of clear zone had the highest sensitivity (80% (95% CI, 72-86%)), and uterovesical interface irregularity exhibited the highest specificity (99% (95% CI, 97-100%)).
CONCLUSIONS: First-trimester ultrasound examination has similar accuracy to second- and third-trimester ultrasound examinations for the diagnosis of PAS. Routine first-trimester ultrasound screening for patients at high risk of PAS may improve detection rates and allow earlier referral to tertiary care centers for pregnancy management. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

UNASSIGNED: Under some circumstances, individuals choose to undergo pregnancy termination for foetal anomalies in the second half of pregnancy. This report provides objective information on the clinical management of such cases and a systematic review of the literature on labour induction outcomes for third-trimester abortion using mifepristone-misoprostol.
UNASSIGNED: The study is a case series describing outcomes for labour induction abortion for foetal anomalies, at gestational age 24 weeks and beyond. A systematic review was performed, searching PubMed, Embase, and Cochrane databases. Two independent authors reviewed and quality assessed the data from the articles.
UNASSIGNED: During a two-year period, 15 patients met inclusion criteria. Fourteen patients received mifepristone and misoprostol, and one received oxytocin. All delivered vaginally. Thirteen patients delivered within 24 hours of the first misoprostol dose, and half delivered within 12 hours. The average interval from misoprostol initiation to foetal expulsion was 15.5 hours in our series. The systematic review identified nine articles for inclusion, all retrospective studies. Labour induction protocols for mifepristone-misoprostol, reporting of gestational age, and key comparisons varied greatly.
UNASSIGNED: The case series illustrates successful termination of pregnancy primarily using combined mifepristone-misoprostol. Certainty of current evidence is low, based on the GRADE framework. Future research is necessary on third-trimester outcomes with mifepristone-misoprostol.

Background and Objectives: Since spontaneous uterine rupture in the mid-trimester is rare, maternal and fetal outcomes in subsequent pregnancies remain unclear. Therefore, this study aimed to examine the maternal and fetal outcomes of subsequent pregnancies after prior mid-trimester uterine rupture. Materials and Methods: A systematic review using PubMed, the Cochrane Central Register of Controlled Trials, and Scopus until 30 September 2021, was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The studies that clarified the maternal and fetal outcomes after prior mid-trimester uterine rupture and our case (n = 1) were included in the analysis. Results: Among the eligible cases, there were five women with eight subsequent pregnancies after prior mid-trimester uterine rupture. The timing of prior mid-trimester uterine rupture ranged from 15 to 26 weeks of gestation. The gestational age at delivery in subsequent pregnancies was 23-38 gestational weeks. Among the included cases (n = 8), those involving prior mid-trimester uterine rupture appeared to be associated with an increased prevalence of placenta accreta spectrum (PAS) (n = 3, 37.5%) compared with those involving term uterine rupture published in the literature; moreover, one case exhibited recurrent uterine rupture at 23 weeks of gestation (12.5%). No maternal deaths have been reported in subsequent pregnancies following prior mid-trimester uterine rupture. Fetal outcomes were feasible, except for one pregnancy with recurrent mid-trimester uterine rupture at 23 weeks of gestation, whose fetus was alive complicated by cerebral palsy. Conclusions: Our findings suggest that clinicians should be aware of the possibility of PAS and possible uterine rupture in pregnancies after prior mid-trimester uterine rupture. Further case studies are warranted to assess maternal and fetal outcomes in pregnancies following prior mid-trimester prior uterine rupture.

BACKGROUND: Recent medical literature has drawn attention to the possible influence of COVID-19 on the course of pregnancies. As the coherence of results seems to vary, especially in relation to first and second trimester pregnancies, a concise qualitative systematic review can shed light on the most recent data.
METHODS: A structured systematic search was performed to collect all COVID-19 pregnancy-related articles published between January 1 and September 16, 2020. Two independent reviewers evaluated studies using the STROBE statement in combination with the CERQual quality assessment of findings.
RESULTS: In total 1387 articles were screened and finally 22 studies were evaluated (179 1st/2nd trimesters of pregnant women with COVID-19). The majority of reported mothers who contracted COVID-19 during 1st/2nd trimesters are yet to complete their pregnancy.
CONCLUSIONS: Evidently a limited amount of data is available. Usually, mothers and newborns are discharged from the hospital without any serious complications. Further observations are imperative.

BACKGROUND: Conjoined twins are a rare clinical event occurring in about 1 per 250,000 live births. Though the prognosis of conjoined twins is generally low, there is limited evidence as to the optimal method of pregnancy termination, particularly in cases of advanced gestational age. We report a successful dilation and evacuation (D&E) done for conjoined twins at 22 weeks of gestation.
METHODS: A 20-year-old primigravid woman was diagnosed with a conjoined, thoraco-omphalopagus twin pregnancy after undergoing a detailed two-dimensional (2D) fetal ultrasound anatomic scanning. Assessment and counseling were done by a multidisciplinary team. The team discussed the prognosis and options of management with the patient. The patient opted for termination of pregnancy. Different options of termination were discussed and the patient consented for D&E, with the possibility of reverting to hysterotomy in case intraoperative difficulty was encountered. A 2-day cervical preparation followed by D&E was done under spinal anesthesia and ultrasound guidance.
CONCLUSIONS: In this patient, D&E was done successfully without complications. Adequate cervical preparation, pain control, and ultrasound guidance during the procedure are critical for optimal outcomes. A literature review of methods of pregnancy termination for conjoined twins in the second trimester revealed 75% delivered vaginally through medical induction while 18% underwent cesarean section. Only one other report described successful D&E for conjoined twins after 20 weeks. D&E can be safely performed for carefully selected cases of conjoined twins beyond 20 weeks\' gestations avoiding the need for induction or hysterotomy.

This study aimed to determine the optimal cervical priming regimen before surgical abortion between 14+0 and 24+0 weeks\' gestation.
Embase, MEDLINE, and the Cochrane Library were searched for publications up to February 2020. Experts were consulted for any ongoing or missed trials.
Randomized controlled trials, published in English after 1985, that compared (1) mifepristone, misoprostol, and osmotic dilators against each other, alone or in combination; (2) different doses of mifepristone and misoprostol; (3) different intervals between priming and abortion; or (4) different routes of administration of misoprostol were included.
Risk of bias was assessed using the Cochrane Collaboration checklist for randomized controlled trials, and data were meta-analyzed in Review Manager 5.3. Dichotomous outcomes were analyzed as risk ratios using the Mantel-Haenszel method, and continuous outcomes were analyzed as mean differences using the inverse variance method. Fixed effects models were used when there was no significant heterogeneity (I2<50%), random effects models were used for moderate heterogeneity (I2≤50% and <80%), and evidence was not pooled when there was high heterogeneity (I2≥80%). Subgroup analyses were undertaken based on parity where available. The overall quality of the evidence was assessed using Grades of Recommendation Assessment, Development, and Evaluation.
A total of 15 randomized controlled trials (N=2454) were included and showed decreased difficulty of procedure and/or increased cervical dilation and decreased patient acceptability with regimens that included dilators compared with those that did not include dilators; increased preoperative expulsion of the pregnancy with sublingual misoprostol and mifepristone compared with sublingual misoprostol alone; increased difficulty of procedure with dilators and misoprostol compared with dilators and mifepristone; decreased difficulty of procedure with dilators and mifepristone compared with dilators alone; and increased cervical dilation when dilators were placed the day before abortion compared with the same day.
Considered alongside clinical expertise, the published data support the use of osmotic dilators, misoprostol, or mifepristone before abortion for pregnancies at 14+0 to 16+0 weeks\' gestation; osmotic dilators or misoprostol for pregnancies at 16+1 to 19+0 weeks\' gestation; and osmotic dilators alone or with mifepristone for pregnancies at 19+1 to 24+0 weeks\' gestation. The effectiveness of pharmacologic agents alone beyond 16+0 weeks\' gestation and the optimal timing of dilator placement remain important questions for future research.

UNASSIGNED: Mifepristone and misoprostol are recommended for second-trimester medical abortion, but consensus is unclear on the ideal regimen.
UNASSIGNED: The objectives were to systematically review randomized controlled trials (RCTs) investigating efficacy, safety and satisfaction of medical abortion at ≥ 12 weeks\' gestation.
UNASSIGNED: We searched PubMed, Popline, Embase, Global Index Medicus, Cochrane Controlled Register of Trials and International Clinical Trials Registry Platform from January 2008 to May 2017.
UNASSIGNED: We included RCTs on medical abortion at ≥ 12 weeks\' gestation using mifepristone and/or misoprostol. We excluded studies with spontaneous abortion, fetal demise and mechanical cervical ripening and those not reporting ongoing pregnancy (OP).
UNASSIGNED: After extracting prespecified data and assessing risk of bias in accordance with the Cochrane handbook, we used Revman5 software to combine data and GRADE to assess certainty of evidence.
UNASSIGNED: We included 43 of the 1894 references identified. Combination mifepristone-misoprostol had lower rates of OP [risk ratio (RR) 0.12, 95% confidence interval (CI) 0.04-0.35] vs. misoprostol only. A 24-h interval between mifepristone and misoprostol had lower OP rate at 24 h than simultaneous dosing (RR 3.13, 95% CI 1.23-7.94). Every 3-h dosing had lower OP rate at 48 h (RR 0.39, 95% CI 0.17-0.88).
UNASSIGNED: Direct comparisons of buccal misoprostol to sublingual or vaginal routes after mifepristone were limited. Evidence from clinical trials on how to best manage women with prior uterine incisions was lacking.
UNASSIGNED: Our analysis supports the use of mifepristone 200 mg 1 to 2 days before misoprostol 400 mcg vaginally every 3 h at ≥ 12 weeks\' gestation.
UNASSIGNED: Where available, providers should use mifepristone plus misoprostol for second-trimester medical abortion. Vaginal misoprostol appears to be most efficacious with fewest side effects, but sublingual and buccal routes are also acceptable.

High-quality care for termination of pregnancy (TOP) requires pain to be effectively managed; however, practices differ, and the available guidelines do not specify optimal strategies.
To guide providers in effective pain management for second-trimester medical and surgical TOP.
We searched PubMed, Cochrane and Embase databases, and the US National Library of Medicine clinical trials registry, from inception to the end of June 2019, and hand-searched reference lists.
Trials comparing pain management strategies with no treatment, placebo or active interventions during induced medical or surgical TOP, occurring between 13 and 24 weeks of gestation, and reporting direct or indirect measures of pain.
Both authors summarised and systematically assessed the evidence and risk of bias using standard tools.
We included seven medical and four surgical TOP studies, with 453 and 349 participants, respectively. The heterogeneity of interventions and outcomes prevented pooled analyses. Medical TOP: women receiving routine or continuous epidural analgesia experienced mild pain. The prophylactic use of nonsteroidal anti-inflammatory drugs (NSAIDs) decreased pain (mean difference -0.5, P < 0.001) and additional opioid requirements (3.5 versus 7 mg, P = 0.04) compared with placebo/other treatment. Paracervical block was ineffective. No studies assessed intramuscular (IM)/intravenous (IV) opioid or nonpharmacological treatment. Surgical TOP: general anaesthesia/deep IV sedation alleviated pain. Nitrous oxide was ineffective. No studies assessed moderate IV sedation, IV/IM opioid, paracervical block without sedation, NSAID or nonpharmacological treatment.
Based on limited data, regional analgesia and NSAIDs mitigated second-trimester medical TOP pain; general anaesthesia/deep IV sedation alleviated surgical TOP pain.
Although women experience intense pain during second-trimester termination of pregnancy, few data are available to inform their treatment.
