Predictive analysis of lung function in school-age children born with very low birthweight, according to the definition used of bronchopulmonary dysplasia. A retrospective observational analysis.

Aim: To determine the predictive value of the definition of bronchopulmonary dysplasia (BPD) on spirometric parameters of very low birthweight (VLBW) children of school age between 1 January 2008 and 31 December 2016.

Methods: In this longitudinal retrospective observational study, we analyse a cohort of children admitted to a neonatal intensive care unit between 1 January 2008 and 31 December 2016. All newborns weighing <1500 g and born before 32 weeks of gestational age were included in the study (VLBW newborns).

Analysis of the Association between In Vitro Fertilization/Assisted Conception and the Development of Retinopathy of Prematurity in Very-Low-Birth Weight Newborns.

Objective: The objective is to study to what extent the development of retinopathy of prematurity (ROP) is associated with assisted conception (AC) and in vitro fertilization (IVF) in a tertiary referral hospital.

Materials And Methods: This study is a retrospective observational cohort study. Very-low-birth weight (VLBW) infants with gestational age (GA) <32 weeks or birth weight <1500 g were admitted to the neonatal unit of a tertiary care hospital between January 1, 2011, and December 31, 2021.

Late Neonatal Sepsis in Very-low-birth-weight Premature Newborns Is Associated With Alterations in Neurodevelopment at Twenty-five Months of Age.

Aim: To evaluate the impact of late-onset sepsis (LOS) on the neurodevelopment of very-low-birth-weight (VLBW) premature infants.

Methods: This is a retrospective cohort study of VLBW premature infants. The Mental Development Index (MDI) was determined for a population of 546 VLBW infants, at 14 and 25 months of age, and evaluated using the Bayley test.

Breast-feeding as protective factor against bronchopulmonary dysplasia in preterm infants.

Breast-feeding is associated with fewer comorbidities in very-low-birth-weight (VLBW) preterm infants. Bronchopulmonary dysplasia (BPD) of VLBW infants is a multifactorial pathology in which nutritional aspects may be of special importance. The aim of this study is to determine, in a cohort of VLBW infants, whether breast milk nutrition is associated with a reduced prevalence and severity of BPD.

Laser fetoscopy ablation for twin-twin transfusion syndrome may reduce the risk of ROP.

Purpose: Twin-twin transfusion syndrome (TTTS) is a condition wherein monochorionic twins share a common placenta with placental anastomoses between the two foetal circulations. Most infants who survive TTTS are born prematurely. This study aimed to determine whether fetoscopic laser ablation (FLA) can reduce the risk of retinopathy of prematurity (ROP) and whether TTTS was a risk factor for ROP.

Extrauterine growth restriction and low energy intake during the early neonatal period of very low birth weight infants are associated with decreased lung function in childhood.

Premature birth, bronchopulmonary dysplasia or restrictive nutrition in the first weeks of postnatal life may have repercussions on lung development and affect long-term lung function outcomes. This prospective observational study is based on a cohort of 313 very low birth weight (VLBW) neonates, born between 1 January 2008 and 1 December 2016. The daily intake of calories, protein, fat and carbohydrates during the first week of life and evidence of inadequate weight gain (Δwt) until week 36 of gestational age (GA) were recorded.

Sensitivity and Specificity of the Newborn Infant Parasympathetic Evaluation Index in Pain Assessment of Very Low Birth Weight Infants.

Objective: This article describes the results of a study investigating the sensitivity and specificity of the Newborn Infant Parasympathetic Evaluation (NIPE) index for detecting the physiological changes resulting from nociception in painful procedures in very low birth weight (VLBW) infants.

Study Design: A prospective observational study was carried on of 44 newborns at 23 to 32 weeks' gestational age. The sensitivity and specificity of the NIPE index are analyzed using a receiver operating characteristic curve.

Blood products transfusion and retinopathy of prematurity: A cohort study.

Aim: The aim of the study was to assess the influence of blood product transfusions on the development and severity of retinopathy of prematurity (ROP).

Methods: A retrospective cohort study was conducted of very low birth weight (VLBW) newborns with less than 32 weeks gestational age (GA) admitted to the neonatal unit of a tertiary care hospital during the period from 1 January 2008 to 31 December 2021. Data on the degree of ROP and the transfusions received were obtained and analysed.

Evaluation of Risk and Preventive Factors for Necrotizing Enterocolitis in Premature Newborns. A Systematic Review of the Literature.

Necrotizing enterocolitis (NEC) is a serious condition related to prematurity and the initiation of enteral feeding. In this article, we review the evidence published in recent years on necrotizing enterocolitis risk factors (prematurity, feeding with low-weight formula, existence of intestinal dysbiosis) and protective factors (human milk or donated milk supply, supplementation of human milk with oligosaccharides, probiotics administration, and the determination of disease predictive biomarkers). A systematic review was conducted of preventive, risk and predictive factors for necrotizing enterocolitis in neonates prior to 37 weeks' gestational age, based on a literature search for clinical trials, meta-analyses, randomized controlled trials and systematic reviews published between January 2018 and October 2021.

Effectiveness of two probiotics in preventing necrotising enterocolitis in a cohort of very-low-birth-weight premature new-borns.

According to previous research, the incidence of necrotising enterocolitis (NEC) decreases after supplementation with probiotics. However, few studies have considered the equivalence or otherwise of different strains of probiotics in this respect. Accordingly, this prospective observational study was conducted in a cohort of 245 very-low-birth-weight (VLBW) new-borns to assess the prevalence of NEC after supplementation with the probiotic Inforan (Berna Biotech, Madrid, Spain) 250 mg capsules containing 10 cfu of (ATCC 4356) and 10 cfu of (ATCC 15696); or with Bivos (Ferring, Madrid, Spain) containing (formerly ) (LGG) (ATCC 53103) (10 cfu); or with no probiotic supplementation.

The association between restricted intra-uterine growth and inadequate postnatal nutrition in very-low-birth-weight infants and their neurodevelopmental outcomes: a 50-month follow-up study.

Inadequate nutrition during a critical period of development - as is the case during gestation and the first days of life, especially in very-low-birth-weight (VLBW) infants, can impact on neurodevelopment and favour co-morbidities. In this study, we evaluate how neurodevelopment may be affected by intra-uterine growth (IUGR) restriction and by an inadequate intake of nutritional energy during the early neonatal period. A longitudinal cohort study was conducted to analyse the nutritional contributions received during the first week of life, among a population of 396 VLBW infants.
