Review
This chapter discusses the role of cardiac neural crest cells in the formation of the septum that divides the cardiac arterial pole into separate systemic and pulmonary arteries. Further, cardiac neural crest cells directly support the normal development and patterning of derivatives of the caudal pharyngeal arches, including the great arteries, thymus, thyroid, and parathyroids. Recently, cardiac neural crest cells have also been shown to indirectly influence the development of the secondary heart field, another derivative of the caudal pharynx, by modulating signaling in the pharynx. The contribution and function of the cardiac neural crest cells has been learned in avian models; most of the genes associated with cardiac neural crest function have been identified using mouse models. Together these studies show that the neural crest cells may not only critical for normal cardiovascular development but also may be involved secondarily because they represent a major component in the complex tissue interactions in the caudal pharynx and outflow tract. Cardiac neural crest cells span from the caudal pharynx into the outflow tract, and therefore may be susceptible to any perturbation in or by other cells in these regions. Thus, understanding congenital cardiac outflow malformations in human sequences of malformations resulting from genetic and/or environmental insults necessarily requires better understanding the role of cardiac neural crest cells in cardiac development.

International Journal of Cardiology Jun 2024The purpose of this study was to analyse the association between stannum exposure during pregnancy and congenital heart diseases in offspring.
BACKGROUND
The purpose of this study was to analyse the association between stannum exposure during pregnancy and congenital heart diseases in offspring.
METHODS
Based on a prospective birth cohort study conducted in Gansu Maternal and Child Health Hospital from 2010 to 2012, 14,359 pregnant women were followed up using a nested case-control study method. 97 pregnant women whose offspring were diagnosed with CHDs were used as the case group, and 194 pregnant women whose offspring did not suffer from congenital heart diseases were used as the control group in a ratio of 1:2 according to their age and place of birth. Inductively coupled plasma mass spectrometry was used to determine elemental stannum in blood samples from pregnant women hospitalized for delivery and in fetal cord blood samples. Multifactorial logistic regression analysis was used to assess the association between stannum and offspring CHDs.
RESULTS
There was a moderate positive correlation between the concentration of stannum in pregnant women's blood and that in umbilical cord blood. A higher concentrations of maternal blood stannum level was associated with a greater risk of CHDs (aOR 3.409, 95%CI 1.785-6.826), isolated CHDs (aOR 4.044, 95%CI 1.803-9.070), multiple CHDs (aOR 2.625, 95%CI 1.137-6.061), patent ductus arteriosus (aOR 2.882, 95%CI 1.443-5.756), atrial septal defects (aOR 3.067, 95%CI 1.406-6.690), ventricular septal defects (aOR 7.414, 95%CI 1.414-38.874). There was a correlation between the maternal and cord blood sample suggesting stannum crosses the placenta.

BACKGROUND
To investigate the prognosis of the remaining fetus in twin pregnancy after experiencing one fetal demise in the first trimester according to the location of the demised fetus.
METHODS
This was a retrospective study of twin pregnancies with one fetal demise after the first trimester (14 weeks of gestation) delivered between September 2004 and September 2022. The study population was divided into two groups based on the location of the demised fetus as determined by the last recorded ultrasonography results: Group 1 included twin pregnancies where the presenting fetus was demised (n = 36) and Group 2 included twin pregnancies where the non-presenting fetus was demised (n = 44). The obstetric and neonatal outcomes were also reviewed.
RESULTS
A total of 80 pregnant women were included. The median gestational age for the diagnosis of fetal demise was 24.1 weeks. The gestational age of the demised fetus was not different between Groups 1 and 2; however, the gestational age of the remaining fetus at delivery was significantly earlier in Group 1 than it was in Group 2 (33.8 vs. 37.3 weeks, P = .004). The rate of preterm birth before 28 weeks was almost five times higher in Group 1 than in Group 2 (22.2% vs. 4.5%, P = .037). Regression analysis demonstrated significant differences between Groups 1 and 2. Respiratory distress syndrome, bronchopulmonary dysplasia, patent ductus arteriosus, retinopathy of prematurity, and jaundice were more common in Group 1 than in Group 2; however, the association was not significant after adjusting for gestational age at delivery.
CONCLUSIONS
When the presenting fetus is demised in a twin pregnancy, the remaining fetus tends to be delivered earlier than when the non-presenting fetus is demised.

BACKGROUND
To investigate the concurrent, long-term, and future adverse events and assess the trend of adverse events in pediatric patients with patent ductus arteriosus (PDA) after transcatheter closure.
METHODS
A total of 1590 patients underwent transcatheter PDA closure were enrolled, including 465 patients (median age = 22 months) in the training group and 1125 patients in the validation group. Logistic regression analysis was used to assess independent risk factors associated with concurrent adverse events after closure. The chi-square test was used to evaluate the 5-year follow-up trend.
RESULTS
Multivariable logistic regression analysis indicated that low age, female, and high pulmonary end diameter were independent risk factors for concurrent adverse events after closure. For patients without concurrent adverse events and for those who with concurrent adverse events but return to normal, the Chi-square test showed no abnormal results at the 5-year follow-up. Furthermore, the follow-up data of the validation group were not significantly different from those of the training group.
CONCLUSION
The value of long-term follow-up of children may be limited for those who did not have a concurrent adverse event after closure nor for those who had a concurrent adverse event after closure but returned to normal during the 5-year follow-up period.
IMPACT
Follow-up monitoring of adverse events tended to be recommended in pediatric patients with PDA after transcatheter closure. However, follow-up in these pediatric patients is expensive and there is a risk of sedation for echocardiography examination frequently. ·Patients who had no concurrent adverse events after closure did not show any abnormality at 5-year follow-up. ·Most of the patients who had concurrent adverse events after closure returned to normal at 5-year follow-up. The value of long-term follow-up may be limited for the above patients after transcatheter PDA closure.

Diagnostic approach and treatment of ventricular septal defect associated with PDA, coarctation of aorta, hypoplastic aortic arch and multiple valvular heart disease in a tertiary center: An infrequent association.
Ventricular septal defect is the most common congenital heart disease in children and is associated with patent ductus arteriosus in 1%-7% of cases. The coexistence of both malformities with hypoplastic aortic arch and aortic coarctation is even rarer. We present the case of a 6-year-old girl referred to our hospital because of dyspnea on feeding, recurrent respiratory infections, poor weight gain, and a heart murmur. The image studies revealed a ventricular septal defect, patent ductus arteriosus, severe hypoplasia of the aortic arch with critical stenosis of the proximal portion, severe dilatation of the pulmonary artery and pulmonary, mitral, tricuspid, and aortic regurgitation. We will discuss the diagnostic approach and treatment in a tertiary reference center for patients with cardiovascular diseases.

Meta-Analysis
BACKGROUND AND OBJECTIVE
There is a paucity of pooled synthesized data on the epidemiology of neonatal acute kidney injury (AKI). Our objective with this study is to systematically assess the worldwide incidence of AKI in neonates.
METHODS
We searched 3 electronic databases (Embase, PubMed, Web of Sciences) from January 2004 to December 2022 without language restrictions. We included cohort and cross-sectional studies that reported the incidence of AKI or associated mortality in neonates. Eligible studies had at least 10 participants and used standard criteria (Acute Kidney Injury Network/Pediatric Risk, Injury, Failure, Loss, End Stage Renal Disease (pRIFLE)/ Kidney Disease Improving Global Outcomes) to define AKI. Two authors independently retrieved data on demographic characteristics, clinical setting, and outcomes (incidence and AKI-associated mortality) using a semi-structured proforma and assessed the risk of bias. We used a random-effects meta-analysis to calculate pooled estimates with 95% confidence intervals.
RESULTS
We included 201 studies (98 228 participants) from 45 countries. The incidence of any stage AKI was 30% (95% confidence interval 28-32), and that of severe AKI was 15% (14-16). Overall, AKI-associated mortality was 30% (27-33). The odds of mortality were higher (odds ratio 3.4; 2.9-4.0) in neonates with AKI compared with those without AKI. We found that perinatal asphyxia, sepsis, patent ductus arteriosus, necrotizing enterocolitis, and nephrotoxic medications were significant risk factors for AKI. Significant heterogeneity in the pooled estimates was a limitation of this study.
CONCLUSIONS
AKI was observed in one-third of the neonates and was associated with increased risk of mortality. The incidence of AKI was almost similar in neonates with perinatal asphyxia and sepsis, but mortality was higher in the former group.
