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.

Neonatal FeNO, risk factors, and respiratory morbidity in infants: A cohort study.

Background: Respiratory symptoms in infancy are more common in premature infants. Nitric oxide (NO) is involved in prenatal and neonatal lung development. Measurement of exhaled NO is easy and well-tolerated by neonates.

Exhaled nitric oxide in premature and mature infants during the first months of life.

Aim: In this review, we aim to describe how exhaled Nitric Oxide(NO) changes during the first months of life in premature and mature infants.

Method: Review of the literature up to August 2020, on online, tidal breathing NO measurements in unsedated infants. The association between Fractional exhaled NO(FeNO) values, postnatal age, and prematurity was analysed using linear mixed modeling and Spearman's rank correlation.

Tidal breath eNO measurements in a cohort of unsedated hospitalized neonates-A method validation.

Aim: Exhaled Nitric oxide (eNO) is an inflammatory marker. In 2002 Hall et al. [J Appl Physiol.

[Late debut of neonatal pneumonia caused by Chlamydia trachomatis].

A newborn colonized with Chlamydia trachomatis will often show symptoms of conjunctivitis and/or pneumonia. We report a case of interstitial pneumonia caused by C. trachomatis in a 2-month-old boy admitted with RSV.
