A Case of Neonate with Split Cord Malformation Presenting with Hypoplasia of the Left Lower Extremity.

The frequency of split cord malformation (SCM) is approximately 1 in 5000 births; however, patients are rarely diagnosed with SCM in the neonatal period. Moreover, there have been no reports of SCM with hypoplasia of the lower extremities at birth. A 3-day-old girl was transferred to our hospital for a thorough examination of hypoplasia of the left lower extremity and lumbosacral abnormalities detected after birth.

A COL4A1 variant in a neonate with multiple intracranial hemorrhages and congenital cataracts.

A 2-day-old neonate presented with seizures, multiple intracranial hemorrhages, and bilateral congenital cataracts. Targeted next-generation sequencing of the collagen type IV alpha 1 chain (COL4A1) gene revealed a heterozygous de novo missense variant (NM_001845.6:c.

Growth Trajectories during the First 6 Years in Survivors Born at Less Than 25 Weeks of Gestation Compared with Those between 25 and 29 Weeks.

We aimed to determine the differences in the growth trajectories of the youngest gestational survivors (<25 weeks’ gestation) up to 6 years of age compared to those of older gestational ages. Preterm infants were divided into two groups: 22−24 weeks’ gestation (male (M) 16, female (F) 28) and 25−29 weeks’ gestation (M 84, F 59). Z-scores of body weight (BW), body length (BL), and body mass index (BMI) were derived from Japanese standards at 1, 1.

Resistin in Urine and Breast Milk: Relation to Type of Feeding and Anthropometry at 1-Month.

Breast milk contains adipokines such as resistin and leptin and is known for its protective effect against obesity and insulin resistance. This pilot study aims to evaluate the correlation between resistin levels, feeding types (breast milk and formula), and anthropometric parameters in healthy 1-month-old term infants. Urine and breast milk samples were collected from 32 infants and their mothers at 1 month postpartum.

Avoidance of bottles during the establishment of breastfeeds in preterm infants.

Background: Preterm infants often start milk feeds by gavage tube. As they mature, sucking feeds are gradually introduced. Women with preterm infants may not always be in hospital to breastfeed their baby and need an alternative approach to feeding.

Effect of parenteral lipid emulsion on preterm infant PUFAs and their downstream metabolites.

Objective: Oxylipins synthesized by oxidation of long-chain polyunsaturated fatty acids (LCPUFAs) are bioactive downstream lipid mediators. The aim of this study was to describe oxylipin levels in preterm infants born 30 to 33 weeks' gestation who were enrolled in a randomized controlled trial in which peripheral parenteral nutrition (P-PN), including lipid emulsion (containing soy, medium chain triglyceride, olive and fish oil), was compared with 10% glucose on growth during the transition to enteral feeds.

Methods: Of the 92 infants randomized to the P-PN study, the first 72 (P-PN n = 34, control n = 38) had blood taken for fatty acid analyses.

The efficacy and safety of peripheral intravenous parenteral nutrition vs 10% glucose in preterm infants born 30 to 33 weeks' gestation: a randomised controlled trial.

Background: Preterm infants born 30 to 33 weeks' gestation often require early support with intravenous fluids because of respiratory distress, hypoglycemia or feed intolerance. When full feeds are anticipated to be reached within the first week, risks associated with intravenous delivery mode and type must be carefully considered. Recommendations are for parenteral nutrition to be infused via central venous lines (because of the high osmolarity), however, given the risks associated with central lines, clinicians may opt for 10% glucose via peripheral venous catheter when the need is short-term.

Intravenous fat induces changes in PUFA and their bioactive metabolites: Comparison between Japanese and Australian preterm infants.

Objective: Oxylipins are biologically active signaling molecules that initiate and resolve inflammation; they are synthesized by oxidation of polyunsaturated fatty acids (PUFAs) and reflect PUFA intake and status. The PUFA intake in preterm infants differs between countries because of the type of lipid emulsions used and the PUFA content of breast milk. We compared total blood PUFA, free PUFA and their oxylipin levels in dried whole blood samples from preterm infants born in Australia and Japan.

Correlations between feeding type and blood ionized magnesium levels in Japanese preterm infants.

Although magnesium (Mg) contents are different between breast milk and formula, few studies have investigated the blood Mg level in breast fed or formula fed preterm infants. We examined the influence of feeding type on serum Mg and whole blood ionized Mg (iMg) levels in preterm infants soon after birth. We included 115 preterm infants born between gestational weeks 32 and 35.

Oxylipins and Free Fatty Acids in Parenteral Lipid Emulsions Currently Used in Preterm Infant Care: An In Vitro Study.

Lipid emulsions used to support nutrition in preterm infants contain long-chain polyunsaturated fatty acids (LCPUFAs) as a source of essential fatty acids; these LCPUFAs and their parent polyunsaturated fatty acid (PUFA) can be oxidized by a variety of mechanisms to bioactive molecules called oxylipins, which are signaling molecules that initiate and/or resolve inflammation. The aim of this study was to explore levels of free LCPUFA and their related oxylipins in 3 commercially available lipid emulsions (Intralipid, SMOFlipid, and ClinOleic) using ultra high-performance liquid chromatography mass spectroscopy. Free LCPUFA were detected in all lipid emulsions tested.

A Systematic Review and Meta-Analysis of Human Milk Feeding and Morbidity in Very Low Birth Weight Infants.

This systematic review and meta-analysis synthesised the post-1990 literature examining the effect of human milk on morbidity, specifically necrotising enterocolitis (NEC), late onset sepsis (LOS), retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD) and neurodevelopment in infants born ≤28 weeks' gestation and/or publications with reported infant mean birth weight of ≤1500 g. Online databases including Medline, PubMed, CINAHL, Scopus, and the Cochrane Central Register of Controlled Trials were searched, and comparisons were grouped as follows: exclusive human milk (EHM) versus exclusive preterm formula (EPTF), any human milk (HM) versus EPTF, higher versus lower dose HM, and unpasteurised versus pasteurised HM. Experimental and observational studies were pooled separately in meta-analyses.

Urinary prostaglandin D metabolite excretion during the first six months of life was significantly lower in breast-fed than formula-fed infants.

Aim: The metabolic changes that occur during the postnatal weaning period appear to be particularly important for future health, and breast milk is considered to provide the optimal source of infant nutrition. This pilot study from September 2013 to May 2015 examined the effect of breastfeeding on prostaglandin metabolism in healthy term infants.

Methods: Urine samples were collected from 19 infants at one month of age in the Juntendo University Hospital, Tokyo, Japan.

Avoidance of bottles during the establishment of breast feeds in preterm infants.

Background: Preterm infants start milk feeds by gavage tube. As they mature, sucking feeds are gradually introduced. Women who choose to breast feed their preterm infant are not always able to be in hospital with their baby and need an alternative approach to feeding.

Effect of insulin-like growth factor-I during the early postnatal period in intrauterine growth-restricted rats.

Background: Insulin-like growth factor-I (IGF-I) is essential for perinatal growth and development; low serum IGF-I has been observed during intrauterine growth restriction (IUGR). We investigated the effects of recombinant human (rh) IGF-I in IUGR rats during the early postnatal period.

Methods: Intrauterine growth restriction was induced by bilateral uterine artery ligation in pregnant rats.

A family having type 2B von Willebrand disease with a novel VWF p.R1308S mutation: Detection of characteristic platelet aggregates on peripheral blood smears as the key aspect of diagnosis.

Type 2B von Willebrand disease (VWD) is frequently associated with distinct platelet morphology. Here we present a familial case of type 2B VWD with a novel VWF mutation (p.R1308S), which caused neonatal thrombocytopenia.

Oxidative stress early in infancy and neurodevelopmental outcome in very low-birthweight infants.

Background: Reactive oxygen species may be involved in serious diseases in premature infants. The objective of this study was to assess the relationship between neurodevelopmental outcome and oxidative stress marker level in the urine of very low-birthweight (VLBW) infants.

Methods: Spot urine samples were collected from 35 VLBW infants.

Lipid profile and atherogenic indices soon after birth in Japanese preterm infants.

Aim: The intra-uterine environment affects the risk of development of cardiovascular disease in adulthood. The aim of this study was to determine the influence of prematurity and foetal growth restriction on lipid metabolism, by assessing atherogenic indices soon after birth in preterm infants.

Methods: Blood samples were collected within 20 min of birth from 80 preterm infants with a gestational age of ≤35 weeks.

Fat emulsion given to very low-birthweight infants increases urinary L-FABP.

Background: In premature infants, many factors influence the function of renal tubules, such as asphyxia, respiratory disorders, use of high-concentration oxygen, hypotension, and drug treatment. When tubular ischemia and oxidative stress develop due to renal microcirculatory pathology, urinary L-type fatty acid-binding protein (L-FABP) level increases.

Methods: Urinary L-FABP level was measured over time in very low-birthweight infants (VLBWI), and the effect of fat emulsion on L-FABP level was investigated.

Effect of hypoxic-ischemic insults on the composition of fatty acids in the brain of neonatal rats.

Background: Long-chain polyunsaturated fatty acids, especially docosahexaenoic acid (DHA; 22:6 n-3), comprise a major component of brain membrane phospholipids. The effect of neonatal hypoxic-ischemic insults on brain fatty acid composition is not completely understood. The aim of this study was to investigate alterations in brain fatty acid composition during development and in response to hypoxic-ischemic insults in neonatal rats.
