OBJECTIVE: To evaluate feasibility and initial outcomes of fetoscopic tracheal occlusion for severe diaphragmatic hernia compared with a historical cohort who had not received fetal tracheal occlusion. METHODS: Outcomes in a prospective observational cohort who underwent fetoscopic tracheal occlusion for severe fetal left diaphragmatic hernia without associated anomalies were compared with our historical nontreated cohort of matched fetuses of similar severity. Fetuses were classified using the same ultrasonography and magnetic resonance imaging methodology-prospectively in the fetoscopic tracheal occlusion group and retrospectively in the historical nontreated cohort...

The results of several epidemiological studies and clinical trials investigating the effects of n-3 polyunsaturated fatty acids (PUFAs) on antenatal and postnatal depression remain controversial. In a previous case-control study of early pregnancy in Japan, we found an inverse association between eicosapentaenoic acid and risk of psychological distress after adjusting for possible confounders. Here, in a 1:2 matched case-control study, we further investigated the possible relationship between serum n-3 PUFAs and risk of psychological distress in the second and third trimesters of pregnancy...

OBJECTIVES: Recent research provides evidence that anogenital distance may serve as a novel metric to assess reproductive potential in men. In children, a shorter anogenital distance was linked with cryptorchidism, hypospadias, and micropenis. Scarce data exist in the literature regarding anogenital distance measurement in the fetus. The aim of our study was to assess whether intrauterine measurement of fetal anogenital distance could assist in the differential diagnosis of male genital anomalies...

We have previously shown that endochondral ossification is finely regulated by the Clock system expressed in chondrocytes during postnatal skeletogenesis. Here we show a sophisticated modulation of bone resorption and bone mass by the Clock system through its expression in bone-forming osteoblasts. Brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (Bmal1) and Period1 (Per1) were expressed with oscillatory rhythmicity in the bone in vivo, and circadian rhythm was also observed in cultured osteoblasts of Per1::luciferase transgenic mice...

Introduction: Fetal thrombotic vasculopathy is a recently described placental alteration with varying degrees of involvement and often associated with adverse perinatal outcomes. The diagnosis is made histologically and therefore is postnatal, which makes it a challenge in clinical practice. Method: Case report and review of literature on the subject. Results: The present case refers to a pregnant woman presenting fetal growth restriction, with poor obstetrical past, and sent late to our service...

Notch1 signaling plays a critical role in maintaining and determining neural stem/progenitor cell (NSPC) fate, yet the transcriptional mechanism controlling Notch1 specific expression in NSPCs remains incomplete. Here, we show transcription factor Nkx6.1 interacts with a cis-element (CR2, an evolutionarily conserved non-coding fragment in the second intron of Notch1 locus) and regulates the expression of Notch1 in ventral NSPCs of the developing spinal cord. We show that the Notch1 expression is modulated by the interaction of Nkx6...

PURPOSE: Plasmapheresis in pregnancy adversely affects maternal hemodynamics, however there are studies suggesting it to reduce pregnancy loss in immunological diseases when medication is more harmful to the fetus. The overall optimal plasmapheresis treatment protocol remains unknown. MATERIALS AND METHODS: A pregnant with neuromyelitis optica was followed up after receiving six volumes of fresh frozen plasma via plasmapheresis. RESULTS: The placenta compensated the hemodynamic change until the 33rd week of gestation, resulting a small for gestational age, otherwise healthy girl...

OBJECTIVES: Caffeine (CAF) and sedative/anesthetic drugs (SADs) are often coadministered to premature infants in the neonatal intensive care unit (NICU). While SAD neurotoxicity in the developing brain is well established, it is not fully clear whether CAF interacts with SADs and whether this interaction is detrimental. Using a mouse model of prematurity, we hypothesized that CAF would increase apoptotic neurotoxicity when coadministered with SADs. METHODS: Postnatal day 3 mice were treated with vehicle or 80 mg/kg CAF prior to challenge with 6 mg/kg midazolam, 40 mg/kg ketamine, or 40 μg/kg fentanyl...

The prefrontal cortex (PFC) plays a key role in cognitive functions, memory, and attention. Alterations in parvalbumin interneurons (PV neurons) and perineuronal nets (PNNs) within the PFC have been implicated in schizophrenia and autism spectrum disorder pathology. However, it remains unclear why PV neurons and PNNs in the PFC are selectively impaired. Here we aimed to clarify if PV neurons and PNNs in the PFC have region-specific features. We found that PV neurons and PNNs were increased in a region-specific manner in the PFC during postnatal development...

A cross-fostering design was used to assess the relative involvement of genetic variability and early postnatal experiences on differential levels of playfulness in juvenile Fischer 344 (F344) and Lewis (LEW) rats and the extent to which strain differences in anxiety may influence play in these two strains. F344 dams were found to lick and groom their pups less than LEW dams and this was not dependent upon the strain of the pups in the litter. As expected, F344 rats were less playful than LEW rats as demonstrated by fewer playful contacts directed to the nape of a Sprague-Dawley (SD) partner and a decreased likelihood of rotating completely to a supine position when their nape was contacted by the SD partner...

BACKGROUND: Postnatal growth and repair of skeletal muscle relies upon a population of quiescent muscle precursor cells, called satellite cells that can be activated to proliferate and differentiate into new myofibers, as well as self-renew to replenish the satellite cell population. The balance between differentiation and self-renewal is critical to maintain muscle tissue homeostasis, and alterations in this equilibrium can lead to chronic muscle degeneration. The transcription factor CCAAT/enhancer binding protein beta (C/EBPβ) is expressed in Pax7(+) satellite cells of healthy muscle and is downregulated during myoblast differentiation...

BACKGROUND: Organ regeneration in mammals is hypothesized to require a functional pool of stem or progenitor cells, but the role of these cells in lung regeneration is unknown. METHODS: Based on the fact that postnatal regeneration of alveolar tissue has been attributed to alveolar epithelial cells, we established a hemorrhagic shock and Lipopolysaccharide (LPS) lung injury model. Using this model, we analyzed the cellular kinetics of lung alveolar epithelial cells...

BACKGROUND: Despite advances in neonatal intensive care, germinal matrix-intraventricular hemorrhage (GMH-IVH) remains a frequent, serious complication of premature birth. Neutral head position and head tilting have been suggested to reduce the risk of GMH-IVH in preterm infants during the first 72 h of life. OBJECTIVE: The aim of this study was to provide a systematic review of the effect of neutral head positioning and head tilting on the incidence of GMH-IVH in very preterm infants (gestational age ≤30 weeks)...

BACKGROUND: Anesthesia during the synaptogenic period induces dendritic spine formation, which may affect neurodevelopment. The authors, therefore, evaluated whether changes in synaptic transmission after dendritic spine formation induced by sevoflurane were associated with long-term behavioral changes. The effects of sevoflurane on mitochondrial function were also assessed to further understand the mechanism behind spinogenesis. METHODS: Postnatal day 16 to 17 mice were exposed to sevoflurane (2...

Congenital hyperinsulinism is a serious blood glucose regulation defect that interferes with brain development, leading to mental retardation, neurological sequelae and secondary epilepsy and ultimately may be life-threatening. Congenital hyperinsulinism (CHI) is caused by genetic defects of regulation of insulin secretion that induce insulin oversecretion in intrauterine life and postnatally. The clinical consequence is fetal macrosomia and subsequently neonatal and infantile hypoglycaemia. The most severe form is caused by biallelic mutations of KCNJ11 and ABCC8 genes that encode both potassium channel subunits, whereas their heterozygous mutations as well as enzymatic defects (GLUD1, HADH, GCK) lead to milder presentation...

The pectoral girdle is a complex structure which varies in its morphology between species. A major component in birds is the furcula, which can be considered equivalent to a fusion of the paired clavicles found in many mammals, and the single interclavicle found in many reptiles. These elements are a remnant of the dermal skeleton and the only intramembranous bones in the trunk. Postnatally, the furcula plays important mechanical roles by stabilising the shoulder joint and acting as a mechanical spring during flight...

REVIEW
Heiko J Luhmann
The combination of voltage-sensitive dye imaging (VSDI) with multielectrode array (MEA) recordings in the rodent cerebral cortex in vivo allows the simultaneous analysis of large-scale network interactions and electrophysiological single-unit recordings. Using this approach, distinct patterns of spontaneous and sensory-evoked activity can be recorded in the primary somatosensory (S1) and motor cortex (M1) of newborn rats. Already at the day of birth, gamma oscillations and spindle bursts in the barrel cortex synchronize the activity of a local columnar ensemble, thereby generating an early topographic representation of the sensory periphery...
