Inflammation-induced FGF10 protein deficiency is associated with bronchopulmonary dysplasia (BPD), a chronic lung disease of prematurely born infants characterized by arrested alveolar development. So far, experimental evidence for a direct role of FGF10 in lung disease is lacking. Using the hyperoxia-induced neonatal lung injury as a mouse model of BPD, the impact of Fgf10 deficiency in Fgf10(+/-) versus Fgf10(+/+) pups was investigated. In normoxia, no lethality of Fgf10(+/+) or Fgf10(+/-) pups was observed...

BACKGROUND: In some studies, the dose of intravenous soybean oil (SO) has been associated with a decreased incidence of intestinal failure-associated liver disease. The effect of lipid sparing on neurodevelopment (ND) and growth remains unknown. This study investigated the impact of SO dose on ND and growth over the first 2 years of age in preterm neonates. MATERIALS AND METHODS: This is a single-site prospective follow-up study. Neonates with a gestational age ≤29 weeks were randomized to low-dose (LOW) or standard-dose (CON) SO...

BACKGROUND: Pregnancies resulting through oocyte donation have been associated with increased risk for adverse outcomes for the mother, such as gestational hypertensive disorders. However, little is known about possible neonatal complications of such pregnancies. The purpose of this study was to evaluate the neonatal health outcomes among singleton pregnancies in a population of relatively young and healthy oocyte recipients in Sweden, taking into account the medical indication leading to treatment...

Retinopathy of prematurity (ROP), the most common cause of blindness in premature infants, has long been associated with inner retinal alterations. However, recent studies reveal outer retinal dysfunctions in patients formerly afflicted with ROP. We have recently demonstrated that choroidal involution occurs early in retinopathy. Herein, we investigated the mechanisms underlying the choroidal involution and its long-term impact on retinal function. An oxygen-induced retinopathy (OIR) model was used. In vitro and ex vivo assays were applied to evaluate cytotoxic effects of IL-1β on choroidal endothelium...

A substantial number of mutations have been identified in voltage-gated sodium channel genes that result in various forms of human epilepsy. SCN1A mutations result in a spectrum of severity ranging from mild febrile seizures to Dravet syndrome, an infant-onset epileptic encephalopathy. Dravet syndrome patients experience multiple seizures types that are often refractory to treatment, developmental delays, and elevated risk for SUDEP. The same sodium channel mutation can produce epilepsy phenotypes of varying clinical severity...

Kangaroo Mother Care (KMC) is a human-based care intervention devised to complement neonatal care for low birth weight and premature infants. Kangaroo position (skin-to-skin contact on the mother's chest) offers thermal regulation, physiological stability, appropriate stimulation and enhances bonding and breastfeeding. Kangaroo nutrition is based on breastfeeding and kangaroo discharge policy relies on family empowerment and early discharge in kangaroo position with close ambulatory follow-up. We describe how the evidence has been developed, and how it has been put into practice by means of direct preterm infants care and dissemination of the method, including training of KMC excellence centers in many countries not only in Latin America but worldwide...

Objective: The diagnosis of cancer in pregnancy is rare, but might become more relevant even for head and neck cancer patients due to a shift of age of primipara towards the last third of reproductive years. Unsureness exists about the risk and benefit of diagnostic and therapeutic cancer modalities for the unborn and established recommendations are still missing. But, according to recent data, even multimodal therapeutic approaches (e. g. surgery, radiation, chemotherapy) seem possible in face of pregnancy and should be traded against the risk of prematurity...

CONTEXT: Necrotizing enterocolitis (NEC) is the most frequent gastrointestinal emergency in neonates. The microbiome of the preterm gut may regulate the integrity of the intestinal mucosa. Probiotics may positively contribute to mucosal integrity, potentially reducing the risk of NEC in neonates. OBJECTIVE: To perform an updated systematic review and meta-analysis on the efficacy and safety of probiotics for the prevention of NEC in premature infants. DATA SOURCES: Structured searches were performed in: Medline, Embase, and the Cochrane Central Register of Controlled Trials (all via Ovid, from 2013 to January 2015)...

: We investigated 10 mother-newborn pairs and found a 90% rate of dengue virus (DENV) transmission during the perinatal period. Here, we describe DENV kinetics in the sera of newborns before the onset of disease. Of the breast-milk samples analyzed, 75% tested positive for DENV. BACKGROUND: Dengue is the most common mosquito-borne viral disease in humans. With this study, we aimed to investigate the risk of vertical (DENV) transmission during the peripartum period and to describe its viral kinetics in serum and breast milk...

Bronchopulmonary dysplasia (BPD) is the chronic lung disease associated with premature birth, characterized by impaired vascular and alveolar growth. In neonatal rats bleomycin decreases lung growth and causes pulmonary hypertension (PH), which is poorly responsive to nitric oxide. In the developing lung, through rho-kinase (ROCK) activation, ET-1 impairs endothelial cell function, however, whether ET-1-ROCK interactions contribute to impaired vascular and alveolar growth in experimental BPD is unknown. Neonatal rats were treated daily with intra-peritoneal bleomycin with and without selective ETA (BQ123/BQ610) and ETB (BQ788) receptor blockers, non-selective ET receptor blocker (ETRB) (bosentan) or fasudil (ROCK inhibitor)...

Importance: Metabolic changes after maternal bariatric surgery may affect subsequent fetal development. Many relevant perinatal outcomes have not been studied in this postoperative population, and the risks associated with short operation-to-birth (OTB) intervals have not been well examined. Objective: To examine the risk for perinatal complications in women with a history of bariatric surgery (postoperative mothers [POMs]) by comparing them with mothers without operations (nonoperative mothers [NOMs]) and examining the association of the OTB interval with perinatal outcomes...

Introduction The incidence and risk factors for inguinal hernia (IH) is not a thoroughly evaluated issue of preterms. Prematurity is the single most important risk factor. There exists no study in our country which reported the incidence of IH in preterms. The purpose of this study is to investigate the incidence and time of diagnosis of IH in very low-birth-weight (VLBW) infants. Patients and Methods This retrospective case-control study was conducted in Etlik Zubeyde Hanim Women's Health Training and Research Hospital and included discharged VLBW infants with gestational age less than 32 weeks...

In this article, we reflect upon Carolyn Rovee-Collier's pioneering research on learning and memory in infants, especially that using the mobile conjugate reinforcement task, for our understanding of (a) cognitive development in infants born prematurely and those with Down's syndrome and (b) her prediction that infants' performance in the mobile conjugate reinforcement and similar operant tasks would predict later intellectual functioning. We then examine the implications of her research on time windows (the integration of new information into a memory) and memory reactivation (the retrieval of a forgotten memory as a result of the re-exposure to a component of the original learning experience) for early intervention programs and clinicians treating victims of early trauma...

Introduction: Hospitalization in neonatal intensive care unit may leads to many stresses for premature infants. Since premature infants cannot properly process stressors, identifying interventions that reduce the stress level for them is seems necessary. The aim of present study was to compare the effects of Field massage and Gentle Human Touch (GHT) techniques on the urine level of cortisol, as an indicator of stress in preterm infants. Methods: This randomized, controlled clinical trial was carried out in Al-Zahra hospital, Tabriz...
