#1
Aline C Freitas, Janet E Hill
Bifidobacteria colonize the human gastrointestinal tract, vagina, oral cavity and breast milk. They influence human physiology and nutrition through health-promoting effects, play an important role as primary colonizers of the newborn gut, and contribute to vaginal microbiome homeostasis by producing lactic acid. Nevertheless, the mechanisms by which bifidobacteria are transmitted from mother to infant remains in discussion. Moreover, studies have suggested that Bifidobacterium spp. have specializations for gut colonization, but comparisons of strains of the same bifidobacteria species from different body sites are lacking...

Background: White matter damage (WMD) is a prime risk factor for cerebral palsy, in part occurring unexplained. Though primarily a problem of preterm infants, there is growing evidence that in large newborns cephalopelvic disproportion and prolonged labor are involved. Objective: To explore both incidence of and morphometric risk factors for WMD in term-born infants. Study Design: We related growth variables and risk factors of term-born infants to WMD (61/4,725) using odds ratios of z -score bands...

Bohring-Opitz syndrome (BOS) is a rare disease with a number of characteristic features, including hypertelorism, prominent metopic suture, exophthalmos, cleft palate, abnormal posture, and developmental retardation. Here, we report a BOS patient presenting with lethal persistent pulmonary hypertension of the newborn (PPHN) and inspiratory respiratory failure. The female infant was treated with nitric oxide and vasodilator, which did not improve her condition. The inspiratory respiratory failure required management with deep sedation...

Necrotizing enterocolitis (NEC) is a potentially fatal disease that develops in the intestinal tract of newborn infants. An overactive immune system in the intestinal tract of NEC patients not only propagates inflammation and mediates tissue damage, but may also radiate the disease systemically and impose injury to distant organs. We previously identified impairment in the Treg compartment in NEC patients. Here, we hypothesized that monocytes, which could promote iTreg differentiation both in vitro and in vivo, were dysregulated in NEC infants...

OBJECTIVE: To determine whether monitoring cerebral oxygen tissue saturation (StO2 ) with near-infrared spectroscopy (NIRS) and brain activity with amplitude-integrated electroencephalography (aEEG) can predict infants at risk for intraventricular hemorrhage (IVH) and death in the first 72 hours of life. STUDY DESIGN: A NIRS sensor and electroencephalography leads were placed on 127 newborns <32 weeks of gestational age at birth. Ten minutes of continuous NIRS and aEEG along with heart rate, peripheral arterial oxygen saturation, fraction of inspired oxygen, and mean airway pressure measurements were obtained in the delivery room...

Polychlorinated biphenyls (PCBs) are synthetic chemicals that bioaccumulate in the food chain. PCBs were used primarily for industrial applications due to their insulating and fire retardant properties, but were banned in the 1970s in the United States and in the 1980s in the United Kingdom, as adverse health effects following exposure were identified. Previous studies of populations with high PCB exposure have reported inverse associations with birth weight and gestational length. Birth weight is a powerful predictor of infant survival, and low birth weight can predispose infants to chronic conditions in adult life such as diabetes and cardiovascular diseases...

When newborns are admitted to the neonatal intensive care unit for prematurity or other reasons, parents do not take on the role that they were expecting to assume. That is, they do not become the main caregivers of their children. To address this issue, neonatal units are currently trying to involve parents in the care of their children as soon as possible. Interesting experiences regarding this issue have been published. Most of the experiences show that when parents assume part of the responsibility for caring for their children, breastfeeding is prolonged, hospital-stay lengths decrease, weight gain increases and the numbers of readmissions decrease (1-4)...

Adapting to the cold extrauterine environment after birth is a great challenge for the newborn. Due to their high surface area-to-volume ratio, infants tend to lose more heat to the environment as compared to adults. In addition, human newborns lack sufficiently developed skeletal muscle mass to maintain body temperature through shivering thermogenesis, an important source of heat in cold-exposed adults. Evolution has provided humans and other placental mammals with brown adipose tissue (BAT), a tissue that converts chemically stored energy, in the form of fatty acids and glucose, into heat through non-shivering thermogenesis...

BACKGROUND: The inconsistency in results of cortisol alterations after childhood maltreatment (CM) might arise due to the fact that no study so far considered the effects of environmental factors such as maltreatment load and genetic factors such as the influence of FKBP5 genotype on stress hormone regulation. This study analyzed the interaction between the single nucleotide polymorphism rs1360780 within the FKBP5 gene and the severity of maternal CM experiences (maltreatment load) on hair steroid levels of mother-infant-dyads...

Severe hyperbilirubinemia, which may result in kernicterus, is seen more frequently in low and middle-income countries, such as Indonesia, than in high-income countries. In Indonesia midwives, general practitioners (GPs), and pediatricians are involved in the care of jaundiced newborn infants. It is unknown whether the high incidence of severe hyperbilirubinemia in this country is related to a lack of awareness of existing hyperbilirubinemia guidelines issued by, for example, the World Health Organization, the American Academy of Pediatrics, or the Indonesian Health Ministry, or to a lack of adherence to such guidelines...

Celiac disease (CD) is an immune-mediated enteropathy involving genetic and environmental factors, whose interaction influences disease risk. The intestinal microbiota, including viruses and bacteria, could play a role in the pathological process leading to gluten intolerance. In this study, we investigated the prevalence of pathogens in the intestinal microbiota of infants at familial risk of developing CD. We included 127 full-term newborns with at least one first-degree relative with CD. Infants were classified according to milk-feeding practice (breastfeeding or formula feeding) and HLA-DQ genotype (low, intermediate or high genetic risk)...

PURPOSE: We report a female infant identified by newborn screening for severe combined immunodeficiencies (NBS SCID) with T cell lymphopenia (TCL). The patient had persistently elevated alpha-fetoprotein (AFP) with IgA deficiency, and elevated IgM. Gene sequencing for a SCID panel was uninformative. We sought to determine the cause of the immunodeficiency in this infant. METHODS: We performed whole-exome sequencing (WES) on the patient and parents to identify a genetic diagnosis...

OBJECTIVE:  Infants cared for in a newborn intensive care unit (NICU) experience pain, parental separation, and stress that may approach toxic levels, thus are potentially traumatic. Lack of accepted clinical terminology to describe the infant experience may result in under appreciation of NICU hospitalization on infant and family outcomes. This study explored NICU clinician perceptions of the infant experience and how the terms trauma/traumatic would impact their clinical roles and practices...

BACKGROUND: For 70 years, there has been a search for the optimal oxygenation of premature infants. In spite of the lack of evidence, guidelines have successively reduced oxygenation targets during these years. OBJECTIVES: (1) To present a summary of previously published meta-analyses of 5 randomized studies (NeOProM) which tested a low (85-89%) versus a high (91-95%) oxygen saturation target the first weeks after birth on outcome of immature newborn infants. (2) To present international recommendations for oxygenation the first weeks after birth...

STUDY QUESTION: Is transferring embryos that achieve blastulation on Day 7 effective and safe? SUMMARY ANSWER: Embryos that achieve blastulation on Day 7 resulted in clinically relevant rates of clinical pregnancy (32.5%) and live birth (25.2%), and newborns have a similar risk of low birth weight, congenital malformations or early neonatal death compared with those derived from Days 5 and 6 blastocysts. WHAT IS KNOWN ALREADY: Potential advantages of blastocyst transfer over cleavage embryo transfer have led to a shift toward the former in IVF practice...

Zika virus (ZIKV) disease is a vector-borne infectious disease transmitted by Aedes mosquitoes. Recently, ZIKV has caused outbreaks in most American countries. Areas covered: Publications about neurological complications of ZIKV infection retrieved from pubmed searchers were reviewed, and reference lists and relevant articles from review articles were also examined. Vertical/intrauterine transmission leads to congenital infection and causes microcephaly and congenital ZIKV syndrome. ZIKV preferentially infects human neural progenitor cells and triggers cell apoptosis...

Infants born prematurely are particularly susceptible to respiratory illness due to underdeveloped lungs, which can often result in fatality. Preterm infants in acute stages of respiratory illness typically require mechanical ventilation assistance, and the efficacy of the type of mechanical ventilation and its delivery has been the subject of a number clinical studies. With recent advances in machine learning approaches, particularly deep learning, it may be possible to estimate future responses to mechanical ventilation in real-time, based on ventilation monitoring up to the point of analysis...

BACKGROUND: Multivariate predictive models for estimating the risk of neonatal early-onset sepsis (EOS) are available as a Web-based sepsis risk calculator (SRC) and may reduce the proportion of newborns empirically treated with antibiotics after birth. EOS risk assessment based on such models would require workflow changes at most birth hospitals. METHODS: A multidisciplinary team of obstetric, neonatal, and information technology staff at a large, academic, birth hospital collaborated to implement the SRC...
