Review
BACKGROUND
Pulmonary arteriovenous malformations are abnormal direct connections between the pulmonary artery and pulmonary vein which result in a right-to-left shunt. They are associated with substantial morbidity and mortality mainly from the effects of paradoxical emboli. Potential complications include stroke, cerebral abscess, pulmonary haemorrhage and hypoxaemia. Embolisation is an endovascular intervention based on the occlusion of the feeding arteries the pulmonary arteriovenous malformations thus eliminating the abnormal right-to-left-shunting.
OBJECTIVES
To determine the efficacy and safety of embolisation in patients with pulmonary arteriovenous malformations including a comparison with surgical resection and different embolisation devices.
SEARCH METHODS
We searched the Cystic Fibrosis and Genetic Disorders Group's Trials Register; date of last search: 31 March 2014.We also searched the following databases: the Australian New Zealand Clinical Trials Registry; ClinicalTrials.gov; International Standard Randomised Controlled Trial Number Register; International Clinical Trials Registry Platform Search Portal (last searched 1 July 2014).We checked cross-references and searched references from review articles.
SELECTION CRITERIA
Trials in which individuals with pulmonary arteriovenous malformations were randomly allocated to embolisation compared to no treatment, surgical resection or embolisation using a different embolisation device.
DATA COLLECTION AND ANALYSIS
Studies identified for potential inclusion were independently assessed for eligibility by two authors, with excluded studies further checked by a third author. No trials were identified for inclusion in the review and hence no analysis was performed.
MAIN RESULTS
There were no randomised controlled trials included in the review; one ongoing trial has been identified which may be eligible for inclusion in the future.
AUTHORS' CONCLUSIONS
There is no evidence from randomised controlled trials for embolisation of pulmonary arteriovenous malformations. However, randomised controlled trials are not always feasible on ethical grounds. Accumulated data from observational studies suggest that embolisation reduces morbidity. A standardised approach to reporting with long-term follow-up through registry studies can help to strengthen the evidence for embolisation in the absence of randomised controlled trials.

Meta-Analysis Review
Exercise hypertension is a common occurrence among individuals with aortic coarctation. Although exercise is known to be beneficial among the general population, the risks and benefits of exercise among those with aortic coarctation are less clear. This systematic review evaluates the benefits and risks of exercise for persons with aortic coarctation. Electronic databases were systematically searched (that is, MEDLINE and EMBASE) and key reviews cross-referenced to identify articles for inclusion. Original research articles reporting exercise among individuals with aortic coarctation were included. From 2608 individual citations, 68 eligible articles were identified. Aerobic exercise stress tests were found to be useful for determining exercise hypertension experiences post-surgical repair (N=5), and other long-term secondary findings (N=3). Experiences of exercise hypertension were associated with abnormal cardiac and/or aortic geometry and cardiac function (N=7). Exercise capacity was generally found to be similar to non-aortic coarctation controls post surgery (N=6). Exercise hypertension was experienced by 27% of participants, including 10% of adults and 43% of children/youth. Individuals who experience exercise hypertension experience greater increases in systolic blood pressure with exercise. No investigations identified evaluated forms of exercise other than aerobic stress tests and no exercise training programs have been conducted to date. Exercise stress tests can be valuable in this population for determining exercise hypertension, especially in the year post-surgical repair. Additional research is urgently needed to accurately assess the benefits and risks of exercise and exercise hypertension, and applicability of exercise restrictions for this population.

Review
BACKGROUND
Approximately 7% of girls will have an anatomic abnormality in their reproductive tract, diagnosed before or after puberty.
OBJECTIVE
It is important for providers to be aware of the obstructive reproductive tract conditions, the way in which various conditions present, and the way in which such conditions should be managed.
DESIGN
Systematic review of the literature using the GRADE evidence system.
RESULTS
There is limited data in most areas of obstructive reproductive tract anomalies; however, some retrospective and prospective series with small numbers are still useful to guide clinical practice.
CONCLUSIONS
Recommendations are based on limited or inconsistent scientific evidence. Recommendations are based primarily on consensus and expert opinion.

Review
PURPOSE
Posterior plagiocephaly (PP) is a common clinical condition in pediatric age. There are two main causes of PP: postural plagiocephaly and craniosynostosis. Early diagnosis is important, as it prevents neurological complications and emergencies. Diagnosis in the past was often made late and with imaging tests that subjected the infant to a high radiation load. Suture ultrasound does not use ionizing radiation; it is easy to perform, allows an early diagnosis, and directs toward the execution of the cranial 3D-CT scan, neurosurgical consultation, and possible intervention. The aim of the study is to describe the high sensitivity and specificity of suture ultrasound for the differential diagnosis between plagiocephaly and craniosynostosis.
METHODS
We reported our prospective experience and compared it with the data in the literature through a systematic review. The systematic review was conducted on electronic medical databases (PubMed, Embase, Cochrane Library, Scopus, and Web of Science) evaluating the published literature up to November 2020. According to Preferred Reporting Items for Systematic Reviews and Meta-ANALYSES (PRISMA statement), we identified 2 eligible studies. Additionally, according to AMSTAR 2, all included reviews have been critically rated as high quality. A total of 120 infants with abnormal skull shape were examined in NICU. All underwent clinical and ultrasound examination.
RESULTS
Of the total, 105 (87.5%) had plagiocephaly and 15 dolichocephaly/scaphocephaly (12.5%). None of these had associated other types of malformations and/or neurological disorders. The synostotic suture was identified ultrasonographically in 1 infant and subsequently confirmed by 3D CT scan (100%).
CONCLUSION
Cranial sutures ultrasonography can be considered in infants a selective, excellent screening method for the evaluation of skull shape deformities as first technique before the 3D CT scan exam and subsequent neurosurgical evaluation. Cranial suture ultrasonography should be considered part of clinical practice especially for pediatricians.

Meta-Analysis Review
BACKGROUND
There is no systematic assessment of available evidence on effectiveness and comparative effectiveness of balloon dilatation and stenting for aortic coarctation.
METHODS AND RESULTS
We systematically searched 4 online databases to identify and select relevant studies of balloon dilatation and stenting for aortic coarctation based on a priori criteria (PROSPERO 2014:CRD42014014418). We quantitatively synthesized results for each intervention from single-arm studies and obtained pooled estimates for relative effectiveness from pairwise and network meta-analysis of comparative studies. Our primary analysis included 15 stenting (423 participants) and 12 balloon dilatation studies (361 participants), including patients ≥10 years of age. Post-treatment blood pressure gradient reduction to ≤20 and ≤10 mm Hg was achieved in 89.5% (95% confidence interval, 83.7-95.3) and 66.5% (44.1-88.9%) of patients undergoing balloon dilatation, and in 99.5% (97.5-100.0%) and 93.8% (88.5-99.1%) of patients undergoing stenting, respectively. Odds of achieving ≤20 mm Hg were lower with balloon dilatation as compared with stenting (odds ratio, 0.105 [0.010-0.886]). Thirty-day survival rates were comparable. Numerically more patients undergoing balloon dilatation experienced severe complications during admission (6.4% [2.6-10.2%]) compared with stenting (2.6% [0.5-4.7%]). This was supported by meta-analysis of head-to-head studies (odds ratio, 9.617 [2.654-34.845]) and network meta-analysis (odds ratio, 16.23, 95% credible interval: 4.27-62.77) in a secondary analysis in patients ≥1 month of age, including 57 stenting (3397 participants) and 62 balloon dilatation studies (4331 participants).
CONCLUSIONS
Despite the limitations of the evidence base consisting predominantly of single-arm studies, our review indicates that stenting achieves superior immediate relief of a relevant pressure gradient compared with balloon dilatation.

Review
In order to compile knowledge on deafblindness (DB) and congenital deafblindness (CDB), one important factor is comparison of results between different scientific studies. In an attempt to do a systematic review of the literature on cognitive assessment and CDB, considerable difficulties in determining eligibility of the studies were encountered due to heterogeneity in definitions and inclusion criteria used in the articles. The present systematic review aims to provide both an overview of this terminological and methodological heterogeneity and suggestions for better future research practices. A systematic review of definitions used in (N=30) studies employing psychological assessment of people with CDB served as a sample of the scientific literature on DB and CDB. Absent or heterogeneous definitions and inclusion criteria regarding both DB and CDB are evident in the sample. Fifty percent of the studies reported no definition of DB and 76.7% reported no definition of CDB. Main discrepancies are: (1) medical/functional versus ability/functioning definitions regarding DB; and (2) different criteria for onset of DB in the case of defining CDB (e.g. age versus developmental level). The results of this study call attention to a scientifically inadequate approach to the study of DB and CDB. Findings indicate that clear guidelines for sample descriptions of the DB and/or CDB populations are needed. It is suggested that studies including DB and CDB participants provide the following information: definitions of DB and CDB used; severity of sensory impairments; level of sensory ability in relation to mobility, access to information, and communication; age at onset of DB; and communication as well as language ability at onset of DB.

Review
BACKGROUND
Public concern about potential health risks associated with incineration has prompted studies to investigate the relationship between incineration and risk of cancer, and more recently, birth outcomes. We conducted a systematic review of epidemiologic studies evaluating the relationship between waste incineration and the risk of adverse birth and neonatal outcomes.
METHODS
Literature searches were performed within the MEDLINE database, through PubMed and Ovid interfaces, for the search terms; incineration, birth, reproduction, neonatal, congenital anomalies and all related terms. Here we discuss and critically evaluate the findings of these studies.
RESULTS
A comprehensive literature search yielded fourteen studies, encompassing a range of outcomes (including congenital anomalies, birth weight, twinning, stillbirths, sex ratio and infant death), exposure assessment methods and study designs. For congenital anomalies most studies reported no association with proximity to or emissions from waste incinerators and "all anomalies", but weak associations for neural tube and heart defects and stronger associations with facial clefts and urinary tract defects. There is limited evidence for an association between incineration and twinning and no evidence of an association with birth weight, stillbirths or sex ratio, but this may reflect the sparsity of studies exploring these outcomes.
CONCLUSIONS
The current evidence-base is inconclusive and often limited by problems of exposure assessment, possible residual confounding, lack of statistical power with variability in study design and outcomes. However, we identified a number of higher quality studies reporting significant positive relationships with broad groups of congenital anomalies, warranting further investigation. Future studies should address the identified limitations in order to help improve our understanding of any potential adverse birth outcomes associated with incineration, particularly focussing on broad groups of anomalies, to inform risk assessment and waste policy.

Meta-Analysis Review
INTRODUCTION
Several studies have reported on the maternal age-associated risks of congenital anomalies. However, there is a paucity of studies with comprehensive review of anomalies. We aimed to quantify the risk of birth defects in children born to middle-aged mothers compared with that in children born to young or older mothers.
MATERIAL AND METHODS
We classified maternal ages into three groups: young (<20 years old), middle (20-34 years old) and older age (≥35 years old). Observational studies that met our age criteria were eligible for inclusion. The articles searched using the Embase and MEDLINE databases were those published from 1989 to January 21, 2021. The Newcastle-Ottawa scale was used to assess the risk of bias. If heterogeneity exceeded 50%, the random effect method was used; otherwise, the fixed-effect method was used. Prospero registration number: CRD42021235229.
RESULTS
We included 15 cohort, 14 case-control and 36 cross-sectional studies. The pooled unadjusted odds ratio (95% CI) of any congenital anomaly was 1.64 (1.40-1.92) and 1.05 (0.95-1.15) in the older and young age groups, respectively (very low quality of evidence). The pooled unadjusted odds ratio of chromosomal anomaly was 5.64 (5.13-6.20) and 0.69 (0.54-0.88) in the older and young age groups, respectively. The pooled unadjusted odds ratio of non-chromosomal anomaly was 1.09 (1.01-1.17) and 1.10 (1.01-1.21) in the older and young age groups, respectively (very low quality of evidence). The incidence of abdominal wall defects was increased in children of women in the young maternal age group.
CONCLUSIONS
We identified that very low quality evidence suggests that women in the older maternal age group had increased odds of having children with congenital anomalies compared with those in the 20-34 year age group. There was no increase in odds of children with congenital anomalies in women of <20 year age group except for abdominal defects compared with those in the 20-34 year age group. The results stem from very low quality evidence with no adjustment of confounders.

Meta-Analysis Review
OBJECTIVES
The main aim of this systematic review was to evaluate the prevalence and type of associated anomalies in fetuses with heterotaxy diagnosed prenatally on ultrasound; the perinatal outcome of these fetuses was also studied.
METHODS
An electronic search of MEDLINE, EMBASE and CINAHL databases was performed. Only studies reporting the prenatal diagnosis of isomerism were included. Outcomes observed included associated cardiac and extracardiac anomalies, fetal arrhythmia, abnormal karyotype, type of surgical repair and perinatal mortality. The analysis was stratified according to the type of heterotaxy syndrome (left (LAI) or right (RAI) atrial isomerism). Meta-analyses of proportions were used to combine data. Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for cohort studies.
RESULTS
Sixteen studies (647 fetuses) were included in the analysis. Atrioventricular septal defect was the most common associated major cardiac anomaly found both in fetuses with LAI (pooled proportion (PP), 59.3% (95% CI, 44.0-73.7%)), with obstructive lesions of the right outflow tract occurring in 35.5% of these cases, and in fetuses with RAI (PP, 72.9% (95% CI, 60.4-83.7%)). Fetal arrhythmias occurred in 36.7% (95% CI, 26.9-47.2%) of cases with LAI and were mainly represented by complete atrioventricular block, while this finding was uncommon in cases with RAI (PP, 1.3% (95% CI, 0.2-3.2%)). Abnormal stomach and liver position were found, respectively, in 59.4% (95% CI, 38.1-79.0%) and 32.5% (95% CI, 11.9-57.6%) of cases with LAI, and in 54.5% (95% CI, 38.5-70.1%) and 45.9% (95% CI, 11.3-83.0%) of cases with RAI, while intestinal malrotation was detected in 14.2% (95% CI, 2.5-33.1%) of LAI and 27.1% (95% CI, 7.9-52.0%) of RAI cases. Hydrops developed in 11.8% (95% CI, 2.9-25.6%) of fetuses diagnosed prenatally with LAI. Biventricular repair was accomplished in 78.2% (95% CI, 64.3-89.4%) of cases with LAI, while univentricular repair or palliation was needed in 17.0% (95% CI, 9.7-25.9%); death during or after surgery occurred in 26.8% (95% CI, 4.6-58.7%) of LAI cases. Most children with RAI had univentricular repair and 27.8% (95% CI, 15.5-42.1%) died during or after surgery.
CONCLUSIONS
Fetal heterotaxy is associated with a high prevalence of cardiac and extracardiac anomalies. Approximately one quarter of fetuses with heterotaxy died during or after surgery. Abnormal heart rhythm, especially heart block, is common in fetuses with LAI, while this finding is uncommon in RAI. Biventricular repair was common in LAI while univentricular repair was required in the majority of children affected by RAI. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Meta-Analysis Review
AIMS
To investigate the safety of fluoxetine use during pregnancy, and to better understand the relationship between maternal fluoxetine use during the first trimester and congenital malformations in infants.
METHODS
PubMed and Web of Science databases were systematically searched from inception to 21 March 2016. Additional studies were identified in a manual search of the reference lists. Two reviewers independently extracted data. A third reviewer checked the data. Estimates were pooled using a random-effects model to calculate the summarized relative ratios (RR) and 95% confidence intervals (CI).
RESULTS
Among 1918 initially identified articles, 16 cohort studies were included. The offspring of pregnant women exposed to fluoxetine during the first trimester had a statistically increased risk of major malformations (RR = 1.18, 95% CI = 1.08-1.29), cardiovascular malformations (RR = 1.36, 95% CI = 1.17-1.59), septal defects (RR = 1.38, 95% CI = 1.19-1.61), and non-septal defects (RR = 1.39, 95% CI = 1.12-1.73) with low heterogeneity in infants. There were no significant observations of other system-specific malformations in the nervous system, eye, urogenital system, digestive system, respiratory system, or musculoskeletal system, respectively. There was no indication of publication bias.
CONCLUSIONS
The results of this meta-analysis indicate maternal fluoxetine use is associated with a slightly increased risk of cardiovascular malformations in infants. Health care providers and pregnant women must weigh the risk-benefit potential of these drugs when making decisions about whether to treat with fluoxetine during pregnancy.
