Abstract

Excessive alcohol drinking represents a major social and public health problem for several countries. Alcohol abuse during pregnancy leads to a complex syndrome referred to as fetal alcohol spectrum disorders (FASD), chiefly characterized by mental retardation. The effects of early exposure to ethanol can be reproduced in laboratory animals and this helped to answer several key questions concerning the human pathology. The interest of experimental models of FASD is twofold. First, they increase our knowledge about the dose and modality of alcohol consumption able to induce damaging effects on the developing brain. Second, experimental models of FASD can provide useful hints to elucidate the basic mechanisms leading to the intellectual disability. In fact, experimental exposure to alcohol can be carried out during discrete, often very restricted, time windows. As a consequence, FASD models, though depending on the multifaceted interference of alcohol with several molecular pathways, can provide valuable information about which specific developmental periods and brain areas are critically involved in the genesis of mental retardation. Putting together data obtained through several experimental paradigms of alcohol exposure and those deriving from other genetic and non-genetic models, one can figure out to what extent different types of mental retardation share common pathogenetic mechanisms. The present Research Topic is aimed at establishing the state of the art of the current research on experimental FASD, focusing on differences and homologies with other types of intellectual disability. The ultimate goal is to find out a common roadmap in view of future therapeutical approaches.

Abstract

The aim of this Research Topic was to collate articles describing prediction of outcomes of pre- and perinatal lesions leading to cerebral palsy, basic research in animal models and human subjects, and ideas for, and trials of, interventions in the first two years of life.CP arises from insults to the sensorimotor cortex, subcortical axon tracts and subplate. The aetiology is complex and often multifactorial. The outcome is not simply a loss of voluntary control due to disruption of descending pathways, but also involves abnormal development of reflex and corticospinal circuitry. CP may be viewed as aberrant plasticity in response to a lesion, indeed, abnormalities in movement are subtle at first but develop subsequently. It is misleading to suppose that developmental mechanisms are self-reparative. The challenge is to understand activitydependent fine tuning of neural circuitry during normal development and to find how to promote desirable plasticity whilst limiting undesirable effects following developmental lesions. However, before proposing interventions, we have to develop our ability to predict the severity of neonatal insults.We solicited a variety of articles, including long and short reviews, original research and opinion pieces, from both basic scientists and clinicians. Likewise we, as editors, have complementary knowledge and experience in this area. Anna Basu is an academic pediatric neurologist and Gavin Clowry is a developmental neuroscientist.

Abstract

Mary Ellen Avery was the driving force behind the discipline of Neonatology. She fought against convention when she published her ground-breaking paper in 1959 showing that Hyaline Membrane Disease was caused by lung surfactant deficiency. Up until then it was thought to be an due to amniotic fluid aspiration, as suggested by Hoccheim in 1903. She encouraged her students to think out of the box, as long as we were studying ‘something that you couldn’t live without’. In addition to being a great clinician-researcher she was a mentor. The article is by her former students writing about their personal experiences under the tutelage of Mel Avery.

Abstract

Pediatric resuscitation medicine has witnessed significant advances with improved understanding of the pathophysiology of cardiac arrest and resuscitation. Multiple mechanisms of neurological injury have been identified, outlining potential avenues for neuroprotection following cardiac arrest. Resuscitation science exists at multiple levels of analysis, from biomechanics of chest compressions to implementation of best training procedures in real time, from epidemiology of cardiac arrest survival to molecular mechanisms of cellular injury due to ischemia and reperfusion. What next steps in research and in clinical practice will ensure the best possible neurologic outcome among children who survive cardiac arrest? How can we leverage novel technologies in neuroimaging, nanomaterials, drug delivery, biomarker-based risk stratification and next generation sequencing, among others, to resuscitate and to protect the Central Nervous System (CNS)? How can we improve clinical trial design and data analyses to maintain a robust clinical research infrastructure and to ensure validity and applicability? These are just some of the questions will addressed in this Research Topic. Using evidence-based algorithms and public health approaches to disseminate them, the last decade has seen a paradigm shift in pediatric resuscitation with significantly improved survival from pediatric cardiac arrests. However, neurologic outcome in survivors remains far from optimal. High quality CPR is increasingly recognized as a key factor for improving neurologic outcomes. Advanced technologies allow monitoring the quality of CPR and just-in-time feedback to improve the quality of CPR. Further research is needed to evaluate impact of these technologies on neurologic outcome. The recent American Heart Association CPR guidelines emphasis on Circulation-Airway-Breathing (CAB) approach to CPR needs a careful evaluation in children, in whom timely airway and breathing support are as important as circulation. The growing controversy regarding use of epinephrine, and alternative routes of administration of epinephrine during CPR, warrants further evaluation in the setting of pediatric CPR. Improved outcome of hemodynamic goal-directed CPR over standard CPR in animal models of cardiac arrest has initiated interest in physiology-based CPR, especially in the in-hospital cardiac arrest. Basic and applied-science research have become relevant for specific subpopulations of pediatric cardiac arrest victims and circumstances (e.g., ventricular fibrillation, neonates, congenital heart disease, extracorporeal cardiopulmonary resuscitation). Just-in-time and just-in-place simulation training, which have evolved as training strategies to improve quality of CPR, are being evaluated for outcomes. The concept of just-in-time and just-in-place coaching of CPR providers on high quality CPR is a novel concept which has emerged recently and remains unstudied. Whilst there have been significant advances in newborn stabilization over the last decade many questions remain unanswered. These include the role of delayed cord clamping in preterm infants and term newborns requiring resuscitation, the role of sustained inflations as a method of respiratory support and the role of epinephrine and volume administration in neonatal resuscitation. Novel methods of assessment including the use of end tidal CO2 monitoring, respiratory function monitoring and near infrared spectroscopy warrant further evaluation. The use of transitioning animal models that accurately replicate the newborn circulation with patent fetal shunts are emerging but more assessments in these are required to better establish CPR strategies in newborn infants. Newborn resuscitation training programs have resulted in a reduction in neonatal mortality in the developing world, but key questions remain around the frequency of training, team training methods and the role of simulation training. Post resuscitation interventions, in particular therapeutic hypothermia, has resulted in significant improvements in long-term outcome and there is now a growing interest in adjunct therapies, such as use of melatonin, erythropoietin, or other neuroprotective molecules to improve therapeutic benefits of cooling. Therapeutic hypothermia did not provide any higher benefit than normothermia in children following out of hospital cardiac arrest, although three is considerable debate in the community whether 14% probability of observing a similar outcome if the study were repeated a 100 times applies to an individual child in the PICU. Exciting research is occurring in unraveling connection between inflammation, immune dysregulation and neuroinjury. This will further support research on the use of anti-inflammatory agents and immunomodulators for neuroprotection after cardiac arrest and birth asphyxia.

Abstract

Emerging from the protective environment of the uterus, the newborn is exposed to a myriad of microbes, and quickly establishes a complex microbiome that shapes the infant’s biology in ways that are only now beginning to come to light. Among these exposures are a number of potential pathogens. The host responses to these pathogens in the neonatal period are unique, reflecting a developing immune system even with delivery at term. Preterm infants are delivered at a time when host defense mechanisms are even less developed and therefore face additional risk. As such, the organisms that cause disease in this period are different from the pathogens that are common in other age groups, or the disease they cause manifests in more severe fashion. Developmental alterations in both innate and adaptive immune responses in neonates have been documented among many cell types and pathways over the last several decades. Contemporary insights into the human immune system and methodologies that allow an “omics” approach to these questions have continued to provide new information regarding the mechanisms that underlie the human neonate as an “immunocompromised host.” This Research Topic highlights studies related to this unique host-pathogen interface. Contributions include those related to the innate or adaptive immune system of neonates, their response to microbial colonization or infection, and/or the pathogenesis of microbes causing disease in neonates.

Abstract

The advances in the peri-operative management of congenital heart defects have substantially improved the survival of infants over the last few decades, reaching >95% survival in the reports of the international congenital data-base from the European Association of Cardio-Thoracic Surgery and form the Society of Thoracic Surgery (North-America). Nevertheless, the surviving children often experience neurodevelopmental deficits and behavioral, emotional and social issues. These problems often have a profound impact on the quality of life of the growing population of these children at risk and their families.

Abstract

Gilles de la Tourette Syndrome (TS) is a common, albeit severely under-diagnosed, neuropsychiatric disorder that is caused by a complex genetic basis, interacting with environmental factors. High comorbidity rates with other neurodevelopmental disorders such as attention deficit/hyperactivity disorder and obsessive compulsive disorder raise the intriguing hypothesis of a shared etiological background. Abnormalities of corticostriatal-thalamic-cortical circuits (CSTC) and dysfunction of both dopamine and serotonin neurotransmitter systems are assumed to be associated with TS. Recently, multiple lines of evidence also point towards an important role of additional neurotransmitters such as histamine and glutamate. For a very long time, efforts to elucidate the etiology and pathophysiology of TS have been fragmented and hampered by low statistical power. Finally, after more than two decades of active research aiming to identify the etiology and pathophysiology of TS, we are on the verge of a new era, promising exciting and rapid discoveries in the field. Investigators from around the world, representing multiple disciplines and scientific approaches, are joining their efforts in large-scale initiatives supported both by European Union and US National funding agencies, such as the European-funded EMTICS, TACTICS, and TSGeneSEE consortia, the Marie Curie Initial Training Network TS-EUROTRAIN and the European Society for the Study of TS joining forces with the NIH-funded TSAICG, GGRI, and Tic Genetics consortia. Importantly, all these initiatives are supported by TS patient support and advocacy groups. Multiple resources are being consolidated and coming together to serve the study of TS, including large well-characterized patient cohorts, and specialized epidemiological databases, such as the unique resource of the Netherlands Twin Register. This research topic showcases current large-scale collaborative efforts aiming to elucidate the genetic and neurobiological background of TS, through diverse approaches; from genomewide association studies aiming to identify common variants associated to the disorder to neuroimaging studies and animal models. Furthermore, current approaches on the clinical assessment and management of the disorder are presented. Propelled by the gradual availability of large scale TS cohorts, novel methodologies, and importantly, sheer enthusiasm by multiple researchers working together across different countries, the new era of the neurobiology of TS holds the promise to identify novel targets for improved therapies.
