Background: High-risk infants refer to newborns exposed to high-risk factors in the prenatal, natal or postnatal period. High-risk infants are at high risk of developmental retardation, and early identification of developmental abnormalities plays a vital role in improving high-risk infants' quality of life.
Aims: To describe the neurodevelopment of high-risk infants aged less than 1 year old, and to analyse the incidences and influencing factors of neurodevelopmental abnormalities in order to provide a basis for neurodevelopment monitoring and management of high-risk infants.
Methods: High-risk infants born between January 2016 and December 2016 in the maternity and infant health hospitals of three districts in Shanghai were followed up. The Gesell Developmental Scale was used to assess the neurodevelopmental level at the time of recruitment (0-2 months) and at 9 months. Univariate and multivariate analyses of the influencing factors were conducted.
Results: 484 high-risk infants (male 51%, female 49%) with an average gestation age of 36.5±2.2 weeks were recruited. At the time of recruitment, the average age was 2.1 (0.8) months, and the developmental quotient (DQ) scores of full-term high-risk infants in motor (=3.542, =0.001), cognitive (=3.125, =0.002), language (=3.189, =0.002) and social (=3.316, =0.001) areas were higher than those of preterm infants. The incidences of developmental abnormalities of full-term high-risk infants in motor (χ =9.452, =0.002), cognitive ( =6.258, =0.012), language ( =12.319, =0.001) and social ( =6.811, =0.009) areas were lower than the preterm infants. At 9 months, there was no difference in the DQ scores and incidences of developmental abnormalities in four areas between full-term and preterm high-risk infants, and the incidence of developmental abnormalities was around 10%.
Conclusion: The incidence of neurodevelopmental abnormalities in high-risk infants aged less than 1 year old is high. Preterm birth and parental bad habits are significant factors affecting the neurodevelopment. Monitoring and early interventions help to improve high-risk infants' neurodevelopment.

Preservation of the azygos vein versus ligation of the azygos vein during primary surgical repair of congenital esophageal atresia.

Background: Esophageal atresia is one of the most common life-threatening congenital malformations and is defined as an interruption in the continuity of the esophagus with or without fistula to the trachea or bronchi. Definitive treatment is surgical ligation of the fistula if present and esophageal end-to-end anastomosis of the two pouches, thereby reconstructing the continuity of the esophagus. During this procedure, the surgeon may choose to either ligate or preserve the azygos vein, a major draining vein for the esophagus and surrounding structures, but no definitive consensus on the matter exists.

Background: Patients with congenital heart defects (CHDs) are at higher risk for infectious diseases. This may partly be due to frequent hospital stays and the associated exposure to pathogens. This study aims to provide a comprehensive overview of immunisation coverage among twins in which at least one twin has CHD.

To investigate how a high risk for infant neurological impairment affects the quality of infant verbal interactions, and in particular properties of infant-directed speech, spontaneous interactions between 14 mothers and their 4.5-month-old infants at high risk for neurological disorders (7 female) were recorded and acoustically compared with those of 14 dyads with typically developing infants (8 female). Mothers of at-risk infants had proportionally less voicing, and the proportion of voicing decreased with increasing severity of the infants' long-term outcome.

Background: Patients supported by extracorporeal membrane oxygenation (ECMO) are at a high risk of brain injury, contributing to significant morbidity and mortality. This study aimed to employ machine learning (ML) techniques to predict brain injury in pediatric patients ECMO and identify key variables for future research.
Methods: Data from pediatric patients undergoing ECMO were collected from the Chinese Society of Extracorporeal Life Support (CSECLS) registry database and local hospitals.

Preterm infants are at high risk of developing respiratory distress syndrome (RDS). Mutations in the genes encoding for surfactant proteins B and C or the ATP-binding cassette transporter A3 (ABCA3) are rare but known to be associated with severe RDS and interstitial lung diseases. The exact prevalence of these mutations in the general population is difficult to determine, as they are usually studied in connection with clinical symptoms.
