COVID-19 pandemic in the neonatal intensive care unit: any effect on late-onset sepsis and necrotizing enterocolitis?

The study was aimed at describing potential indirect effects of pandemic-related measures on very-low-birthweight infants in four Italian NICUs. No overall change in late-onset sepsis (LOS) and necrotizing enterocolitis was documented. However, in the NICU where baseline LOS rate was high, a significant reduction in LOS incidence was recorded. Conclusion: COVID-19-related implementation of NICU hygiene policies is likely to reduce the occurrence of LOS in high-risk settings. What is Known: • COVID-19 pandemic has disrupted routine care in Neonatal Intensive Care Units (NICUs), mostly by tightening infection control measures and restricting parental presence in the NICU. • Beyond the described psychological impact of COVID-19 related measures on healthcare workers and NICU families, their consequences in terms of preterm infants' clinical outcomes have not been described in detail yet. What is New: • Strengthened infection-control measures do not seem to have an overall influence on the incidence of necrotising enterocolitis and late-onset sepsis in very-low-birth-weight infants. • However, the implementation of these measures appears to reduce the occurrence of late-onset sepsis in settings where the baseline incidence of the disease is high.

Paediatricians play a key role in preventing early harmful events that could permanently influence the development of the gut microbiota in childhood.

AIM: The development of the gut microbiota occurs primarily during infancy, and growing evidence has emphasised its positive role and implications for human health. The aim of this review was to provide essential knowledge about the gut microbiota and to describe and highlight the importance of the factors that influence the gut microbiota in early life and their potential harmful effects later in life. METHODS: The European Paediatric Association, the Union of the National European Paediatric Societies and Associations, convened a panel of independent European experts to summarise the research on microbiota for general paediatricians. They used PubMed and the Cochrane Library to identify studies published in English up to June 2018. RESULTS: A number of clinical conditions can disrupt the development of a stable gut microbiota. Changes in the microbiome have been documented in many chronic diseases, mainly immune-mediated gastrointestinal and liver diseases, and distinct patterns have been associated with each specific disease. The gut microbiota can be positively modulated with probiotics, prebiotics, synbiotics, paraprobiotics and postbiotics. CONCLUSION: Paediatricians can play a key role in preventing harmful events that could permanently influence the composition and/or function of the gut microbiota. Various treatment strategies can be used.
