INTRODUCTION: Placental histologic examination can assist in revealing the mechanism leading to preterm birth. Accumulating evidence suggests an association between intrauterine pathological processes, morbidity and mortality of premature infants, and their long term outcome. Neonatal brain activity is increasingly monitored in neonatal intensive care units by amplitude integrated EEG (aEEG) and indices of background activity and sleep cycling patterns were correlated with long term outcome...

Phenobarbital is the most commonly used drug for the treatment of neonatal seizures but may induce neurodegeneration in the developing brain. Methylxanthine caffeine is used for the treatment of apnea in newborn infants and appears to be neuroprotective, as shown by antiapoptotic and anti-inflammatory effects in oxidative stress models in newborn rodents and reduced rates of cerebral palsy in human infants treated with caffeine. We hypothesized that caffeine may counteract the proapoptotic effects of phenobarbital in newborn rats...

The preterm born infant's ability to regulate its cerebral blood flow (CBF) is crucial in preventing secondary ischemic and hemorrhagic damage in the developing brain. The relationship between arterial blood pressure (ABP) and CBF estimates, such as regional cerebral oxygenation as measured by near-infrared spectroscopy (NIRS), is an attractive option for continuous non-invasive assessment of cerebrovascular autoregulation. Areas covered: The authors performed a literature search to provide an overview of the current literature on various current clinical practices and methods to measure cerebrovascular autoregulation in the preterm infant by NIRS...

BACKGROUND: Docosahexaenoic (C22:6) and arachidonic (C20:4) acids are long-chain polyunsaturated fatty acids (LC-PUFA) essential to neonatal development, being present in the glycerophospholipids of all organs, particularly the brain. In plasma, LC-PUFAs are mainly present in lipoprotein lipids, which are neutral lipids (triglycerides and cholesterol esters) and glycerophospholipids, like choline containing phosphatidylcholine (PC). PURPOSE: To guide future supplementation strategies of C22:6 and C20:4 in combination with choline, we determined the distribution of C20:4 and C22:6 between PC and neutral lipid...

By definition, autism spectrum disorder (ASD) is a neurodevelopmental disorder that emerges during early childhood. It is during this time that infants and toddlers transition from appearing typical across multiple domains to exhibiting the behavioral phenotype of ASD. Neuroimaging studies focused on this period of development have provided crucial knowledge pertaining to this process, including possible mechanisms underlying pathogenesis of the disorder and offering the possibility of prodromal or presymptomatic prediction of risk...

Broadband near-infrared spectroscopy (NIRS) can provide an endogenous indicator of tissue temperature based on the temperature dependence of the water absorption spectrum. We describe a first evaluation of the calibration and prediction of brain tissue temperature obtained during hypothermia in newborn piglets (animal dataset) and rewarming in newborn infants (human dataset) based on measured body (rectal) temperature. The calibration using partial least squares regression proved to be a reliable method to predict brain tissue temperature with respect to core body temperature in the wavelength interval of 720 to 880 nm with a strong mean predictive power of [Formula: see text] (animal dataset) and [Formula: see text] (human dataset)...

Neonatal encephalopathy due to hypoxic-ischemic (HI) brain injury triggers a wave of neuroinflammatory events attributed to causing the progressive degeneration and functional deficits seen weeks after the initial insult. In a recent set of studies, we evaluated the therapeutic efficacy of a small molecule antagonist for ALK5 (activin-like kinase 5 ), TGF-β receptor in a rat model of moderate perinatal HI and found significant improvements in neurologic outcomes. Here, we have extended those studies to evaluate the efficacy of delayed TGF-β receptor antagonism on postnatal day (P) 6 and P9 HI rat pups with and without hypothermia...

This review describes the maturational features of the baseline electroencephalogram (EEG) in the neurologically healthy preterm infant. Features such as continuity, sleep state, synchrony and transient waveforms are described, even from extremely preterm infants and includes abundant illustrated examples. The physiological significance of these EEG features and their relationship to neurodevelopment is highlighted where known. This review also demonstrates the importance of multichannel conventional EEG monitoring for preterm infants as many of the features described are not apparent if limited channel EEG monitors are used...

Children under three comprise a sizable and growing proportion of foster care placements. Very young children who enter the child welfare system experience disruptions of critical attachments that are essential to this formative stage of brain development, as well as other traumatic events, leaving them at great risk for lifelong impairments. To reverse these concerning outcomes, babies who have been removed from their homes require intensive, relationship-based interventions that promote secure attachment to a primary caregiver and holistic attention the child's developmental needs...

Pregnant women living in or traveling to areas with local mosquito-borne Zika virus transmission are at risk for Zika virus infection, which can lead to severe fetal and infant brain abnormalities and microcephaly (1). In February 2016, CDC recommended 1) routine testing for Zika virus infection of asymptomatic pregnant women living in areas with ongoing local Zika virus transmission at the first prenatal care visit, 2) retesting during the second trimester for women who initially test negative, and 3) testing of pregnant women with signs or symptoms consistent with Zika virus disease (e...

The immediate and long term effects of exposure to early life stress (ELS) have been documented in humans and animal models. Even relatively brief periods of stress during the first 10 days of life in rodents can impact later behavioral regulation and the vulnerability to develop adult pathologies, in particular an impairment of cognitive functions and neurogenesis, but also modified social, emotional and conditioned fear responses. The development of preclinical models of ELS exposure allows the examination of mechanisms and testing of therapeutic approaches that are not possible in humans...

Creatine is one of the most popular nutritional ergogenic aids for athletes. Studies have consistently shown that creatine supplementation increases intramuscular creatine concentrations which may help explain the observed improvements in high intensity exercise performance leading to greater training adaptations. In addition to athletic and exercise improvement, research has shown that creatine supplementation may enhance post-exercise recovery, injury prevention, thermoregulation, rehabilitation, and concussion and/or spinal cord neuroprotection...

Ictal blinking (IB) is a very rare disease manifesting as an epileptic motor event in children and adults. Until now it has not been included in any classification of focal seizures of the International League Against Epilepsy Commission. It could be unilateral or bilateral, isolated or in association with other motor manifestations such as limbs' clonus and spasms. Its pathogenesis has not been clearly established: paroxysmal discharges from different areas of the brain could cause IB by activation of trigeminal fibers...

Infantile amnesia, the inability of adults to recollect early episodic memories, is associated with the rapid forgetting that occurs in childhood. It has been suggested that infantile amnesia is due to the underdevelopment of the infant brain, which would preclude memory consolidation, or to deficits in memory retrieval. Although early memories are inaccessible to adults, early-life events, such as neglect or aversive experiences, can greatly impact adult behavior and may predispose individuals to various psychopathologies...
