Cohort profile: the vitamin A and D and nitric oxide (AD-ON) observational cohort on lung development and symptoms in premature and mature children in North Zealand, Denmark.

Purpose: The risk of developing asthma-like symptoms and asthma in childhood is influenced by genetics, environmental exposures, prenatal and early postnatal events, and their interactions. The cohort name refers to vitamins A and D, and nitric oxide (NO) spelt backwards and this cohort profile paper aims to present the data collection and aim of the cohort.The overall aim when establishing this cohort was to investigate if childhood lung function can be traced back to early neonatal lung function and fractional exhaled NO (FeNO) and investigate prenatal and postnatal risk factors including maternal and neonatal vitamin A and D levels in preterm and term born children.

Clinical assessment of blood pressure in 60 girls with Turner syndrome compared to 1888 healthy Danish girls.

Objective: Hypertension contributes to increased risk of cardiovascular disease in patients with Turner syndrome (TS). Our objective was to evaluate blood pressure (BP) in girls with TS followed longitudinally through childhood and adolescence compared to a newly established BP reference material.

Design: Cohort study with data collected from 1991 to 2019 consisting of a population-based reference cohort and a group of girls with TS followed at a single tertiary centre.

Postoperative dysnatremia in infants after open-heart surgery occurs frequently and is associated with prolonged intensive care length of stay.

Background: Dysnatremia after surgery for congenital heart disease (CHD) is well known and has been associated with prolonged pediatric intensive care unit length of stay (PICU-LOS). Fluctuations in plasma sodium levels occur perioperatively. The primary aim of the study was to evaluate the occurrence of dysnatremia during the first 48 h after surgery and whether it was associated with PICU-LOS.

Transthoracic Vector Flow Imaging in Pediatric Patients with Valvular Stenosis - A Proof of Concept Study.

Continuous wave Doppler ultrasound is routinely used to detect cardiac valve stenoses. Vector flow imaging (VFI) is an angle-independent real-time ultrasound method that can quantify flow complexity. We aimed to evaluate if quantification of flow complexity could reliably assess valvular stenosis in pediatric patients.

[Preoperative risk assessment of patients with congenital heart disease in non-cardiac surgery].

Over the last decades, remarkable advances in survival in patients with congenital heart disease (CHD) have been reported. Currently, 90% of infants born with CHD can expect to reach adulthood. Moderate and severe CHD is associated with increased perioperative mortality.

Left ventricular thrombus in multisystem inflammatory syndrome in children associated with COVID-19.

A 17-year-old adolescent with severe multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease-2019 developed reduced left ventricular function and left ventricular thrombus. With treatment, his condition improved and the thrombus was dissolved. This case illustrates the risk of severe intra-cardiac thrombotic complications in patients with MIS-C.

Liver fibrosis in patients with tetralogy of Fallot, an unrecognised complication?

Objectives: Improved survival has led to a growing population of adults with congenital heart disease (CHD), followed by numerous reports of late complications. Liver disease is a known complication in some patients, with most studies focusing on Fontan associated liver disease. Whether liver disease also exists in other patients with CHD is not fully investigated.
