Fortified human milk is the first choice for preterm infants. Although individualized fortification is recommended, the optimal method for this population remains uncertain. We conducted a comparative study assessing the growth effects of adjusted (AF) and targeted fortification (TF) in extremely low birth weight (ELBW) infants.

Background: FICare model has been evaluated mostly on the stable preterm infant.We have scaled the model to two implementation levels(basic/advanced),making it suitable for all high-risk neonates.We report on the short- and mid-term outcomes of infants enrolled in a pilot on FICare implementation at our NICU.

Background: Insulin might be associated with changes in infant gastrointestinal microbiota. The objective of this randomized controlled trial was to assess the efficacy of two doses of recombinant human(rh) enteral insulin administration compared to placebo in intestinal microbiota.

Methods: 19 preterm patients were recruited at the NICU of La Paz University Hospital (Madrid, Spain).

Objective: To evaluate changes in blood long-chain polyunsaturated fatty acid (LCPUFA) and oxylipin concentrations in very preterm infants from birth to 36 weeks' postmenstrual age (WPA) after providing an emulsified arachidonic acid (ARA):docosahexaenoic acid (DHA) supplement at two different concentrations.

Study Design: This prospective, randomized trial assigned infants to receive a supplement (1) 80:40 group (80 mg/kg/day ARA and 40 mg/kg/day DHA, = 9) or (2) 120:60 group (120 mg/kg/day ARA and 60 mg/kg/day DHA, = 9). Infants received supplement daily from birth until 36 WPA.

Objective: To evaluate the effect of a new probiotic strain combination, Ligilactobacillus salivarius subsp infantis PS11603 and Bifidobacterium longum PS10402, on gut bacterial colonization of preterm infants.

Methods: A randomized, double-blind, placebo-controlled study was conducted in preterm infants from 28 weeks + 0days to 30 weeks + 6days of gestation. Thirty preterm infants were randomly selected after birth to receive either probiotics or placebo.

Introduction: Monitoring of brain function using continuous electroencephalography (aEEG/cEEG) is an essential tool in the standard care of the term infant, and its use is growing in the premature infant as a biomarker of lesion and brain maturity. However, the placing of the electrodes is a great challenge, particularly in the extremely premature infant, which often discourages neuromonitoring. The aim of this study is to assess the different electrodes available, to select the one that best suits the peculiarities of the extremely premature infant, and evaluate its applicability in clinical practice.

Family Integrated Care (FICare) integrates parents in the direct care of their child while the healthcare personnel act as teachers and guides. To this date, most reports on the feasibility of this model refer to stable preterm infants admitted to Neonatal Intensive Care Units (NICUs). To scale up and adapt FICare to make it suitable in level IIIC NICUs, which care for extreme prematurity and other complex medical or surgical neonatal conditions.

The current 2019 coronavirus disease (COVID-19) is the world's largest and most pervasive public health emergency in more than one hundred years. Although neonatal units have not been at the epicentre of the current health crisis, they have also been forced to adopt contingency plans with the aim of protecting hospitalised neonates, their families, and professionals. Neonatal units have been forced to alter the neonatal care framework based on promoting neurodevelopment and family-centred care.

Article Synopsis
  • The study focuses on how gut microbiota develops in low-birth-weight preterm infants in a neonatal intensive care unit (NICU) over the first three weeks of life, comparing their microbiota during a S. marcescens outbreak to a control group.
  • Results showed that antibiotic exposure likely delayed the expected expansion of gut bacteria, leading to increased levels of harmful bacteria like E. coli and Serratia, particularly during the outbreak, while reducing beneficial Firmicutes.
  • The research highlights that preterm infants' gut microbiota is initially shaped by their hospital environment, with a tendency for rapid bacterial transmission and a significant impact of hospital outbreaks on microbiota development.

Human milk fat is a concentrated source of energy and provides essential and long chain polyunsaturated fatty acids. According to previous experiments, human milk fat is partially lost during continuous enteral nutrition. However, these experiments were done over relatively short infusion times, and a complete profile of the lost fatty acids was never measured.

This document is the result of previous work carried out by different expert groups and submitted to multidisciplinary debate at a Conference about controversial, deficient, or new aspects in the field of neonatal palliative care, such as: 1) the deliberative decision-making process, 2) hospital and domiciliary palliative care, 3) donation after controlled cardiac death, and 4) moral stress in professionals. The most relevant conclusions were: the need to instruct professionals in bioethics and in the deliberative method to facilitate thorough and reasonable decision-making; the lack of development in the field of perinatal palliative care and domiciliary palliative care in hospitals that attend newborns; the need to provide neonatal units with resources that help train professionals in communication skills and in the management of moral distress, as well as delineate operational procedure and guidelines for neonatal organ donation.

The preterm infant gut has been described as immature and colonized by an aberrant microbiota. Therefore, the use of probiotics is an attractive practice in hospitals to try to reduce morbidity and mortality in this population. The objective of this pilot study was to elucidate if administration of two probiotic strains isolated from human milk to preterm infants led to their presence in feces.
