European Radiology Feb 2024To develop and validate MRI-based scoring models for predicting placenta accreta spectrum (PAS) invasiveness. (Meta-Analysis)
Meta-Analysis
OBJECTIVES
To develop and validate MRI-based scoring models for predicting placenta accreta spectrum (PAS) invasiveness.
MATERIALS AND METHODS
This retrospective study comprised a derivation cohort and a validation cohort. The derivation cohort came from a systematic review of published studies evaluating the diagnostic performance of MRI signs for PAS and/or placenta percreta in high-risk women. The significant signs were identified and used to develop prediction models for PAS and placenta percreta. Between 2016 and 2021, consecutive high-risk pregnant women for PAS who underwent placental MRI constituted the validation cohort. Two radiologists independently evaluated the MRI signs. The reference standard was intraoperative and pathologic findings. The predictive ability of MRI-based models was evaluated using the area under the curve (AUC).
RESULTS
The derivation cohort included 26 studies involving 2568 women and the validation cohort consisted of 294 women with PAS diagnosed in 258 women (88%). Quantitative meta-analysis revealed that T2-dark bands, placental/uterine bulge, loss of T2 hypointense interface, bladder wall interruption, placental heterogeneity, and abnormal intraplacental vascularity were associated with both PAS and placenta percreta, and myometrial thinning and focal exophytic mass were exclusively associated with PAS. The PAS model was validated with an AUC of 0.90 (95% CI: 0.86, 0.93) for predicting PAS and 0.85 (95% CI: 0.79, 0.90) for adverse peripartum outcome; the placenta percreta model showed an AUC of 0.92 (95% CI: 0.86, 0.98) for predicting placenta percreta.
CONCLUSION
MRI-based scoring models established based on quantitative meta-analysis can accurately predict PAS, placenta percreta, and adverse peripartum outcome.
CLINICAL RELEVANCE STATEMENT
These proposed MRI-based scoring models could help accurately predict PAS invasiveness and provide evidence-based risk stratification in the management of high-risk pregnant women for PAS.
KEY POINTS
• Accurately identifying placenta accreta spectrum (PAS) and assessing its invasiveness depending solely on individual MRI signs remained challenging. • MRI-based scoring models, established through quantitative meta-analysis of multiple MRI signs, offered the potential to predict PAS invasiveness in high-risk pregnant women. • These MRI-based models allowed for evidence-based risk stratification in the management of pregnancies suspected of having PAS.

BACKGROUND
The lifelong risks of cardiovascular disease following preeclampsia and gestational hypertension are well-established. However, it is unclear whether this evidence has been translated into clinical practice guidelines. Thus, this review aimed to assess the quality and content of Australian clinical practice guidelines regarding the risk of cardiovascular disease following gestational hypertension and preeclampsia.
METHODS
We conducted a systematic search of MEDLINE (Ovid), EMBASE (Ovid), and CINAHL databases, as well as hospital, obstetric society, and medical college websites. Publications were included if: they were a clinical practice guideline; were published in the previous ten years; and included recommendations for the management of future cardiovascular disease risk following hypertensive disorders of pregnancy. Quality assessment was performed using Appraisal of Guidelines for Research and Evaluation Instrument Version Two (AGREE-II) and AGREE Recommendations Excellence Instrument (AGREE-REX).
RESULTS
Eighteen guidelines were identified, and of these, less than half (n = 8) included recommendations for managing future cardiovascular risk following hypertensive disorders of pregnancy. Across these eight, four main counselling recommendations were found regarding (1) risk of future cardiovascular disease; (2) risk factor screening; (3) lifestyle interventions; and (4) prenatal counselling for future pregnancies. The quality and content of these recommendations varied significantly, and the majority of guidelines (87.5%) were assessed as low to moderate quality.
CONCLUSIONS
There are limited Australian clinical practice guidelines providing appropriate advice regarding future risk of cardiovascular disease following hypertensive disorders of pregnancy. The quality and content of these guidelines varied significantly. These findings highlight the need for improved translation from evidence-based research to enhance clinical care and guidance.

Archives of Disease in Childhood. Fetal... Dec 2023To describe families' experiences of antenatal counselling of spina bifida.
OBJECTIVE
To describe families' experiences of antenatal counselling of spina bifida.
DESIGN
Systematic review.
METHODS
MEDLINE, CINAHL, PsycINFO and Embase databases were searched using a combination of Medical Subject Headings and text/abstract terms. Case reports, survey results and qualitative interview data were included. The quality of research was evaluated using the Critical Appraisal Skills Programme checklist.
RESULTS
8 papers were included. Families described shock and grief at diagnosis, with some immediately offered termination of pregnancy (TOP) even though they knew little about the condition. Positive and negative aspects of care were found. Teams that were gentle, kind and empathetic, who did not use jargon, and highlighted positive and negative aspects of the baby's life were seen favourably. Callous language, and overly negative or incorrect counselling was not, particularly if there was pressure to agree to TOP. Families based their decisions on how they would cope, the effect on siblings and the baby's likely quality of life. Prenatal surgery was viewed positively. The views of families who chose TOP, were happy with their care, partners, families, and the LGBTQ+ community were under-represented in the literature.
CONCLUSIONS
Unlike other conditions where limited data on outcome exist or the spectrum is genuinely broad, the outcomes of children with spina bifida is well described. Poor aspects of antenatal counselling were described frequently by families, and further work is needed to capture the full spectrum of views on antenatal counselling, how it can be improved, and what training and resources healthcare professionals need to perform it better.

Meta-Analysis
BACKGROUND
Pseudoamniotic band sequence (PABS) is a rare iatrogenic consequence of invasive fetal interventions, most commonly fetoscopic laser surgery (FLS) in monochorionic multiple pregnancies complicated by twin-to-twin transfusion syndrome (TTTS).
OBJECTIVES
The aim of this study was to investigate prenatal risk factors and perinatal outcomes for pregnancies involving PABS after FLS for TTTS and compare outcomes between those undergoing fetoscopic band release versus not.
METHOD
We conducted a systematic search of PubMed, Scopus, and Web of Science on studies reporting PABS following FLS for TTTS. A meta-analysis of pooled proportions was conducted.
RESULTS
There were 16 studies covering 47 pregnancies complicated by PABS following FLS, mostly case series and case reports. The incidence of PABS was 2%, with the recipient twin affected in 94% of the cases. Pregnancies complicated by PABS were associated with inter-twin septostomy in 32% and chorioamniotic separation (CAS) in 90%. The mean gestational age (GA) at FLS and delivery were 17.7 and 30.9 weeks, respectively. Preterm premature rupture of membranes (PPROM) happened in 62% of pregnancies. The risk of preterm birth (PTB) <34 weeks, <32 weeks, and <28 weeks were 94%, 67%, and 31%, respectively. There were 41% fetal demises and 64% live births among the affected fetuses. Results of fetoscopic band release versus not were comparable, including GA at delivery, PPROM, and PTB at 32 weeks. It was noted that the likelihood of PTB by 28 weeks (67% vs. 23%) and fetal death (50% vs. 39%) were higher in the band release group. It was similar between groups in terms of postnatal amputation.
CONCLUSIONS
PABS causes amputations or fetal death in more than one-third of cases. Pregnancies with an inter-twin septostomy, CAS, advanced TTTS staging, and early GA are more likely to experience PABS. In addition, more than a third of FLS-treated TTTS resulted in PTB and PPROM. PABS cases with prenatal band release showed higher rates of PTB and fetal death, but the data were from small, heterogeneous studies.

Meta-Analysis
ETHNOPHARMACOLOGICAL RELEVANCE
Tanreqing injection (TRQI) is an intravenous herbal preparation derived from 5 types of traditional Chinese medicines including Scutellariae Radix, Lonicerae Japonicae Flos, Forsythiae Fructus, bear bile powder and goral horn, incorporating baicalin, chlorogenic acid, ursodeoxycholic acid, and goose deoxycholic acid and other compounds known for anti-inflammatory properties, is widely used in China to treat cough caused by acute trachea-bronchitis disease (ATB).
AIM OF THE STUDY
To investigate the clinical efficacy and safety of Tanreqing injection (TRQI) with and without Western medicine (WM) for cough caused by acute trachea-bronchitis (ATB).
MATERIALS AND METHODS
We systematically searched eight databases, including CENTRAL, Embase, PubMed, Science Direct, Wiley, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and WanFang, from inception to August 2023 for randomized clinical trials (RCTs) on TRQI for cough caused by ATB. The critical outcomes of interest were time to symptom disappearance, including time for cough symptom to disappear and time to improve cough and sputum production. Important outcomes included symptom disappearance rate, adverse events (AEs) and lung function. We carried out random-effects meta-analysis using Review Manager 5.4 and assessed the certainty of evidence utilizing the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
RESULTS
A total of 2872 citations were identified by our search, of which 26 eligible RCTs enrolled 2731 participants. Low to moderate certainty evidence showed that when compared with WM, TRQI plus WM treatment was associated with a favorable effect on the time for cough symptom to disappear (MD -2.21 d, 95% CI -2.64 to -1.78), time to improve cough and sputum production (MD -0.68 d, 95% CI -0.83 to -0.53), symptom disappearance rate (RR 1.37, 95% CI 1.20 to 1.55), forced vital capacity, and forced expiratory volume in 1 s (MD 0.38 L, 95% CI 0.26 to 0.50; MD 2.92%, 95% CI 1.29 to 4.56, respectively). In terms of AEs, there was no association between TRQI plus WM and WM (RR 0.55, 95% CI 0.14 to 2.21; low-certainty evidence). Very low certainty evidence showed that TRQI alone was associated with reduced time to improve cough and sputum (MD -0.14 d, 95% CI -0.26 to -0.02) and increased symptom disappearance rate (RR 1.89, 95% CI 1.24 to 2.88; low certainty evidence) compared to WM.
CONCLUSIONS
The overall efficacy of TRQI or WM for ATB cough is better than that of WM, and TRQI also effectively improve symptoms in patients with similar adverse events. However, due to the lack of methodological rigor of included studies, the present findings should be interpreted with caution. We advocate better high-quality and convincing clinical studies to be performed to prove the effectiveness and safety of TRQIs.

OBJECTIVE
Stress is a known risk factor for numerous psychopathologies, whereas evidence is lacking regarding the specific consequences of stress on the neural basis of attention-deficit hyperactivity disorder (ADHD). A systematic literature review was thus conducted to clarify the role of stress in the association between the resulting alterations of brain structure, connectivity, and function in ADHD.
METHODS
The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under identifier CRD42023379809. A systematic search of the PubMed and CINAHL databases was conducted for articles published prior to December 22nd, 2022. Retrieved literature was screened in Rayyan and data extraction was performed with respect to neuroimaging, stress exposure, and ADHD outcomes. The Quality in Prognosis Studies (QUIPS) tool was adapted based on the Conducting Systematic Reviews and Meta-Analyses of Observational Studies of Etiology (COSMOS-E) guidance article to assess risk of bias and quality of studies. Strength of the evidence was assessed under the guidance of the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system.
RESULTS
Screening 25,026 non-duplicate articles yielded 20 eligible studies for inclusion. Exposure to early life trauma, institutionalization, prenatal smoking or alcohol consumption, air pollution, low socioeconomic status, or low birth weight were associated with alterations in brain structure, function, and connectivity in ADHD. However, most studies did not provide strong evidence due to small sample sizes and lack of statistical approaches to determine a direct mediation of the association between stress and ADHD by neural outcomes.
CONCLUSION
This systematic review was the first to summarize evidence of structural and functional stress-associated alterations in the brain, which were found to be directly and indirectly associated with ADHD outcomes. Overall, stress requires consideration as a significant determinant of neurodevelopmental outcomes in ADHD. However, extensive further research is warranted due to little available evidence and the difficulty of obtaining clear results. In light of such a complex research question, in order to confirm findings, provide further evidence, and establish causality systematic longitudinal studies would be required. Investigating the topic may provide invaluable information when it comes to tailoring prevention and treatment strategies in ADHD, and should be pursued in order to integrate the factor of stress into a more comprehensive understanding of ADHD.

Meta-Analysis
OBJECTIVES
To assess the diagnostic accuracy of two-dimensional ultrasound at 11-14 weeks' gestation as a screening test for individual fetal anomalies and to identify factors impacting on screening performance.
METHODS
This was a systematic review and meta-analysis that was developed and registered with PROSPERO (CRD42018111781). MEDLINE, EMBASE, Web of Science Core Collection and the Cochrane Library were searched for studies evaluating the diagnostic accuracy of screening for 16 predefined, non-cardiac, congenital anomalies considered to be of interest to the early anomaly scan. We included prospective and retrospective studies from any healthcare setting conducted in low-risk, mixed-risk and unselected populations. The reference standard was the detection of an anomaly on postnatal or postmortem examination. Data were extracted to populate 2 × 2 tables and a random-effects model was used to determine the diagnostic accuracy of screening for the predefined anomalies (individually and as a composite). Secondary analyses were performed to determine the impact on detection rates of imaging protocol, type of ultrasound modality, publication year and index of sonographer suspicion at the time of scanning. Post-hoc secondary analysis was conducted to assess performance among studies published during or after 2010. Risk of bias assessment and quality assessment were undertaken for included studies using the Quality Assessment of Diagnostic Accuracy Studies-2 tool.
RESULTS
From 5684 citations, 202 papers underwent full-text review, resulting in the inclusion of 52 studies comprising 527 837 fetuses, of which 2399 were affected by one or more of the 16 predefined anomalies. Individual anomalies were not equally amenable to detection on first-trimester ultrasound: a high (> 80%) detection rate was reported for severe conditions, including acrania (98%), gastroschisis (96%), exomphalos (95%) and holoprosencephaly (88%); the detection rate was lower for open spina bifida (69%), lower urinary tract obstruction (66%), lethal skeletal dysplasias (57%) and limb-reduction defects (50%); and the detection rate was below 50% for facial clefts (43%), polydactyly (40%) and congenital diaphragmatic hernia (38%). Conditions with a low (< 30%) detection rate included bilateral renal agenesis (25%), closed spina bifida (21%), isolated cleft lip (14%) and talipes (11%). Specificity was > 99% for all anomalies. Secondary analysis showed that detection improved with advancing publication year, and that the use of imaging protocols had a statistically significant impact on screening performance (P < 0.0001).
CONCLUSIONS
The accurate detection of congenital anomalies using first-trimester ultrasound is feasible, although detection rates and false-positive rates depend on the type of anomaly. The use of a standardized protocol allows for diagnostic performance to be maximized, particularly for the detection of spina bifida, facial clefts and limb-reduction defects. Highlighting the types of anomalies amenable to diagnosis and determining factors enhancing screening performance can support the development of first-trimester anomaly screening programs. © 2024 The Authors.

Meta-Analysis
OBJECTIVES
Vascular rings may cause tracheal and/or oesophageal compression. For many patients, symptoms/signs have been present for a long period before diagnosis. However, in the era of prenatal diagnosis, some units advocate universal early surgery. The risks and efficacy of surgery must be known to adequately counsel for the operation. This meta-analysis sought to define the morbidity and mortality associated with surgical correction, and persistent post-operative symptoms.
METHODS
PubMed, Cochrane Library and CINAHL databases were searched for studies that described the outcome of patients undergoing surgery for a double or right aortic arch (DAA or RAA). Non-comparative and random effects model-based meta-analyses were conducted to calculate the pooled rates of mortality, surgical complications, reintervention, and persistent follow-up symptoms.
RESULTS
Nineteen eligible studies were included comprising 18 studies describing outcomes for DAA surgery and 15 for RAA surgery. For DAA surgery, overall mortality rate was 0% [95% confidence interval (CI) 0.0-1.0], post-surgical complication rate 18% [95% CI: 12.0-23.0], prevalence of reintervention 3% [95% CI: 1.0-5.0] and prevalence of symptoms at last follow-up was 33% [95% CI: 17.0-52.0]. For RAA surgery, overall pooled mortality was 0% [95% CI: 0.0-0.0], prevalence of post-surgical complications was 15% [95% CI: 8.0-23.0], reintervention rate was 2% [95% CI: 0.0-4.0], prevalence of symptoms at last follow-up was 40% [95% CI: 26.0-55.0].
CONCLUSIONS
While surgery to correct a vascular ring is safe, the rate of persistent symptoms is high and further strategies must be sought to reduce this burden.

Review
Umbilical Artery Thrombosis (UAT) is an extremely rare complication of pregnancy strongly associated with severe fetal distress and death. The pathogenesis is still unclear but it is often associated with anatomical cord abnormalities that leads to blood stasis and thrombosis formation. Other possible risk factors are maternal thrombophilia, autoimmune disease, gestational diabetes, hypertension disorders of pregnancy and Rh-alloimmunization. The most common clinical symptom is the reduction of fetal movements. The diagnosis is histopathological, but it can be suspected by clinical and prenatal ultrasound findings. Generally, the first choice therapy is the immediate delivery with cesarean section. This study reported a case of a spontaneous intrauterine UAT in a low-risk pregnancy and a systematic review of the literature on clinical, ultrasound and histopathological findings of UAT, in order to help clinicians in the diagnostic process and management of this rare complication.

BACKGROUND
The prenatal diagnosis of a fetal anomaly is unexpected, creating a family crisis. Expectant parents are at an increased risk for perinatal depression and traumatic stress. Prior reviews examined parents' experiences when terminating but not continuing the pregnancy. This review synthesized qualitative research to describe the experiences, emotional responses, and needs of families continuing their pregnancy.
METHODS
An integrative review was performed using the Whitemore and Knafl methodology and PRISMA guidelines. A systematic review of peer-reviewed articles published between 2000 and 2200 on the experiences of fetal anomaly was performed using 5 databases. Eligible articles included qualitative studies describing families' experiences with a fetal anomaly diagnosis who elected to continue their pregnancy. Methodological quality was evaluated using the Critical Skills Appraisal Program checklist.
RESULTS
Of the 678 article results, 16 met inclusion criteria. There were 298 participants from 5 countries. The major overarching theme of Response to the Diagnosis of Fetal Anomaly was identified. The major categories were emotional response, coping strategies, influences, health care experiences, and family needs. Uncertainty and grief were the most common emotions.
DISCUSSION
Parents choosing to continue pregnancy benefit from compassionate, sensitive care, and accurate, concise information, provided in tailored instruction using multiple styles.
