Objective To assess neonatal SARS-CoV-2 anti-spike IgG antibody levels after maternal mRNA COVID-19 vaccination and/or infection during pregnancy and evaluate their protective effect. Methods Prospective observational study, conducted from January 2021 to December 2022. Infants were tested for anti-spike IgG antibodies at birth and then every 3 mo...

Background As Chromium (Cr) is known to contaminate components of parenteral nutrition (PN), Cr-free PN is recommended for preterm infants. Exposure to Cr by PN in preterm infants is scarcely investigated. Objective To describe Cr levels in plasma (Crp) and urine (Cru) during the first month of life in premature newborns ≤ 1500 g of birthweight (B...

Background: The benefits of facilitating breastmilk feeding and close contact between mother and neonate (family-centred care; FCC) in the perinatal period are well-established. The aim of this study was to determine how the delivery of FCC practices were impacted for neonates born to mothers with perinatal SARS-CoV-2 infection during the COVID-19...

Objective: High manganese (Mn) levels during fetal growth or prolonged parenteral nutrition (PN) may have adverse effects on neurodevelopment. We aim to report on Mn levels and their short term impact on clinical course in very low birth weight infants. Study design: An observational study including newborns with a gestational age (GA) ≤32 weeks...

Background and Objectives Swallowing disorders lead to chronic lung aspiration. Early detection and treatment of aspiration in children with dysphagia is important to prevent lung damage. Diagnosis of aspiration, which may be silent, requires an instrumental study such as fiberoptic endoscopic evaluation of swallowing (FEES). Despite its usefulness...

Aim: Due to reduced PaO2, aircrafts at cruising altitudes are pressurized to a cabin altitude of 2438m, equivalent to breathing FiO2 0.15. Portable oxygen concentrators (POCs) are approved for onboard oxygen supply with lack of evidence, especially in infants. We assessed POCs (continuous-flow cPOC vs. pulsed-flow pPOC) under simulated altitude co...

Background: Newborns diagnosed with craniofacial malformations or laryngeal and tracheal alterations may often need advanced airway-management for airway stabilization. Although fiberoptic bronchoscopy (FB) is currently the gold standard for difficult airway management, there is a scarcity of published data on the application of FB in newborns for...

Objectives: Swallowing disorders which lead to aspiration are common in premature infants with a postmenstrual age (PMA) of >36 weeks. Aspiration is often silent and the unique symptom is desaturation during feeding. The aim of this study was 1) to determine the number of prematures with desaturations during feeding due to aspiration, using Fibero...

Background: Preflight hypoxia challenge testing (HCT) in a body plethysmograph has previously been done only on infants >3 months of corrected gestational age (CGA). This study aims to determine the earliest fit-to-fly age by testing neonates <1 week old. Methods: A prospective observational study was carried out on 3 groups of infants: healthy...

Objective: To evaluate the incidence, onset, duration, characteristics and importance of late-onset neutropenia (defined as absolute neutrophil count<1500 μl(-1) at 3 weeks of age or later) in a group of very low birth weight (VLBW) infants. Study design: Routine complete blood cell counts (CBCs) obtained from VLBW infants over a period of 7 yea...

Congenital Langerhans cell histiocytosis is usually limited to cutaneous lesions and has a good prognosis. In rare cases of gut involvement, mortality is high and early and aggressive treatment essential. We report a case of histiocytosis in a newborn with bowel involvement, and performed a literature review of 13 similar cases worldwide documented...
