Autism spectrum disorders (ASD) represent a variety of disorders characterized as complex lifelong neurodevelopment disabilities, which may affect the ability of communication and socialization, including typical comportments like repetitive and stereotyped behavior. Other comorbidities are usually present, such as echolalia, hypotonia, intellectual disability and difficulties in processing figured speech. Furthermore, some ASD individuals may present certain abilities, such as eidetic memory, outstanding musical or painting talents and special mathematical skills, among others...

BACKGROUND: Manganese (Mn) is an essential metal that can become neurotoxic at elevated levels with negative consequences on neurodevelopment. We have evaluated the influence of single nucleotide polymorphisms (SNPs) in Mn transporter genes SLC30A10 and SLC39A8 on Mn concentrations in dentine, a validated biomarker that reflects Mn tissue concentrations early in life. METHODS: The study included 195 children with variable environmental Mn exposure. Mn concentrations in dentine representing fetal, early postnatal and early childhood developmental periods were measured using laser ablation-inductively coupled plasma mass spectrometry...

BACKGROUND: Thyroid hormones are essential for growth and brain development in childhood. Although congenital hypothyroidism (CH) is the most common reason for mental retardation, normal neurological development can be achieved through early and effective treatment. The aim of the present study was to evaluate the neurological development of CH patients aged 24-56 months. METHODS: The study included a total of 116 healthy control subjects and 112 patients aged 24-56 months who were diagnosed with CH during the neonatal period and were being followed up at the Pediatric Endocrinology Department, Keçiören Training and Research Hospital, between 2012 and 2015...

BACKGROUND: Carbon-dioxide (CO2)-pneumothorax during minimally invasive surgery induces well-known metabolic changes. However, little is known about its impact on the central nervous system. The aim of this work is to evaluate the acute impact of CO2-pneumothorax over central cytokine response and its long-term effect on animal behavior. METHODS: This is an experimental study where neonatal Sprague-Dawley rats are submitted to CO2-pneumothorax. Peripheral and central cytokine response was evaluated 24h after insufflation, and peripheral immune cell phenotyping was evaluated 24h and 4weeks post-insufflation...

Our understanding of adipose tissue as an endocrine organ has been transformed over the last 20 years. During this time, a number of adipocyte-derived factors or adipokines have been identified. This article will review evidence for how adipokines acting via the central nervous system (CNS) regulate normal physiology and disease pathology. The reported CNS-mediated effects of adipokines are varied and include the regulation of energy homeostasis, autonomic nervous system activity, the reproductive axis, neurodevelopment, cardiovascular function, and cognition...

BACKGROUND: Exclusion from school is increasingly recognized as pertinent to child health. National educational data reveal that boys, children who are looked-after, living in poverty, have special educational needs, or from certain ethnic minorities, are disproportionately excluded from school. As population-based data on the wider characteristics of excluded children are scarce, we aimed to describe predictors of school exclusion in the Avon Longitudinal Study of Parents and Children...

During the course of adolescence, reductions occur in cortical thickness and gray matter (GM) volume, along with a 65% reduction in slow-wave (delta) activity during sleep (SWA) but empirical data linking these structural brain and functional sleep differences, is lacking. Here, we investigated specifically whether age-related differences in cortical thickness and GM volume and cortical thickness accounted for the typical age-related difference in slow-wave (delta) activity (SWA) during sleep. 132 healthy participants (age 12-21 years) from the National Consortium on Alcohol and NeuroDevelopment in Adolescence study were included in this cross-sectional analysis of baseline polysomnographic, electroencephalographic, and magnetic resonance imaging data...

BACKGROUND: We sought to determine if HIV-exposed uninfected (HEU) children had worse neurodevelopmental outcomes at 24 months compared with HIV-unexposed uninfected (HUU) children in Botswana. METHODS: HIV-infected and uninfected mothers enrolled in a prospective observational study ("Tshipidi") in Botswana from May 2010 to July 2012. Child neurodevelopment was assessed at 24 months with the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III: cognitive, gross motor, fine motor, expressive language, and receptive language domains) and the Development Milestones Checklist (DMC), a caregiver-completed questionnaire (locomotor, fine motor, language and personal-social domains)...

Early exposure to environmental toxins like lead, air pollution, and arsenic can have long-lasting and irreversible consequences for children's neurodevelopment, especially in the developing world. Though the number of pollutants increases each year, some neuroscientists are forging partnerships to improve measurement, raise awareness, and promote global health.

Oral gavage is a popular route of drug administration during preclinical testing. Despite the growing body of information regarding the effects of oral gavage and the stress associated with this technique, the consequences of such exposure during pregnancy or lactation have rarely been investigated. Therefore, we sought to determine the consequences of oral gavage exposure during pregnancy and lactation on the neurodevelopment and behavior of rat offspring. Pregnant Sprague-Dawley dams underwent either no treatment or oral gavage of distilled water once daily from gestational day 7 until postnatal day 21...

One third of humans are infected lifelong with the brain-dwelling, protozoan parasite, Toxoplasma gondii. Approximately fifteen million of these have congenital toxoplasmosis. Although neurobehavioral disease is associated with seropositivity, causality is unproven. To better understand what this parasite does to human brains, we performed a comprehensive systems analysis of the infected brain: We identified susceptibility genes for congenital toxoplasmosis in our cohort of infected humans and found these genes are expressed in human brain...

BACKGROUND: Breast milk alone, given at standard recommended volumes (150 to 180 mL/kg/d), is not adequate to meet the protein, energy, and other nutrient requirements of growing preterm or low birth weight infants. One strategy that may be used to address these potential nutrient deficits is to give infants enteral feeds in excess of 200 mL/kg/d ('high-volume' feeds). This approach may increase nutrient uptake and growth rates, but concerns include that high-volume enteral feeds may cause feed intolerance, gastro-oesophageal reflux, aspiration pneumonia, necrotising enterocolitis, or complications related to fluid overload, including patent ductus arteriosus and bronchopulmonary dysplasia...

Changes in resident microbiota may have wide-ranging effects on human health. We investigated whether early life microbial disruption alters neurodevelopment and behavior in larval zebrafish. Conventionally colonized, axenic, and axenic larvae colonized at 1 day post fertilization (dpf) were evaluated using a standard locomotor assay. At 10 dpf, axenic zebrafish exhibited hyperactivity compared to conventionalized and conventionally colonized controls. Impairment of host colonization using antibiotics also caused hyperactivity in conventionally colonized larvae...

Enterovirus (EV) and human parechovirus (HPeV) are major causes of sepsis-like illness in infants under 90 days of age and have been identified as neurotropic. Studies about acute and long-term neurodevelopment in infants with sepsis-like illness without the need for intensive care are few. This study investigates cerebral imaging and neurodevelopmental outcome following EV and HPeV infection in these infants. We studied infants under 90 days of age who were admitted to a medium care unit with proven EV- or HPeV-induced sepsis-like illness...

High throughput experiments are becoming increasingly common, and scientists must balance hypothesis driven experiments with genome wide data acquisition. We sought to predict novel genes involved in Drosophila learning and long-term memory from existing public high-throughput data. We performed an analysis using PILGRM, which analyzes public gene expression compendia using machine learning. We evaluated the top prediction alongside genes involved in learning and memory in IMP, an interface for functional relationship networks...

Perinatal hypoxia leads to behavioral abnormalities, cognitive disabilities, and epilepsy resulting from alterations in neurodevelopment, maturation and construction of the network. Considering a particular role of γ-aminobutyric acid (GABA) for an immature brain, we analysed transporter-mediated [(3)H]GABA uptake in the cortical, hippocampal and thalamic nerve terminals isolated from rats of different age in the control and after perinatal hypoxia. The state of hypoxia was induced by exposure of rats at the age of 10 postnatal days (pd) (that corresponds approximately to the time of birth in humans) to a respiratory medium with low O2 content (4% O2 and 96%N2) for 12min (up to the initiation of clonico-tonic seizures)...
