BACKGROUND: We attempt to develop a relatively comprehensive structural model of risk factors for drug abuse (DA) in Swedish men that illustrates developmental and mediational processes. METHODS: We examined 20 risk factors for DA in 48,369 men undergoing conscription examinations in 1969-70 followed until 2011 when 2.34% (n=1134) of them had DA ascertained in medical, criminal and pharmacy registries. Risk factors were organized into four developmental tiers reflecting i) birth, ii) childhood/early adolescence, iii) late adolescence, and iv) young adulthood...

The science of early childhood development underscores that maltreatment and other adversities experienced during infancy heightens the risk for poor developmental and socio-emotional outcomes. Referrals to supportive services by the child welfare system are particularly critical during infancy given the rapidity of brain development and infants' sensitivity to their environment. The main objectives of the current study are to: (1) examine age-specific differences in clinical and case characteristics; (2) determine the factors associated with the service referral decision involving infants; and (3) explore the types of services families have been referred to at the conclusion of a maltreatment-related investigation...

BACKGROUND: The first three years of a child's life are a critical period for brain growth and development. Caregiver interventions during this period that improve early childhood health and development have the potential to enhance a child's physical, mental, and social well-being. METHODS: This was a pretest/posttest quasi experimental program evaluation. Early childhood education materials were adapted to create two separate interventions consisting of 30-page interactive flipchart talks to educate mothers on health and development topics relevant to 0-6 and 6-12 month old children...

Perfluorinated alkylate substances (PFASs) are highly persistent and may cause immunotoxic effects. PFAS-associated attenuated antibody responses to childhood vaccines may be affected by PFAS exposures during infancy, where breastfeeding adds to PFAS exposures. Of 490 members of a Faroese birth cohort, 275 and 349 participated in clinical examinations and provided blood samples at ages 18 months and 5 years. PFAS concentrations were measured at birth and at the clinical examinations. Using information on duration of breastfeeding, serum-PFAS concentration profiles during infancy were estimated...

INTRODUCTION: In utero exposure to dioxin-like compounds (DLCs) may cause imbalance of immune development in early infancy. However, there are few epidemiological studies into the effects of in utero exposure to DLCs on allergies and infections during childhood. This study evaluates associations between concentrations of maternal DLCs and cord blood immunoglobulin (Ig) E, as well as allergies and infections during childhood. METHOD: We recruited 514 pregnant women in a maternity hospital in Sapporo, Japan, and measured concentrations of DLCs in 426 maternal blood samples using high-resolution gas chromatography/high-resolution mass spectrometry...

Antenatal brain hypoxia-ischemia, which occurs in cerebral palsy, is considered a significant cause of motor impairments in children. The mechanisms by which antenatal hypoxia-ischemia causes brain injury and motor deficits still need to be elucidated. Tetrahydrobiopterin is an important enzyme cofactor that is necessary to produce neurotransmitters and to maintain the redox status of the brain. A genetic deficiency of this cofactor from mutations of biosynthetic or recycling enzymes is a well-recognized factor in the development of childhood neurological disorders characterized by motor impairments, developmental delay, and encephalopathy...

Better cognitive performance and greater cortical and hippocampal volume have been observed in individuals who undertook aerobic exercise during childhood and adolescence. One possible explanation for these beneficial effects is that juvenile physical exercise enables better neural development and hence more cells and neuronal circuitries. It is probable that such effects occur through intracellular signaling proteins associated with cell growth, proliferation and survival. Based on this information, we evaluated the number of neuronal and non-neuronal cells using isotropic fractionation and the expression and activation of intracellular proteins (ERK, CREB Akt, mTOR and p70S6K) in the cerebral cortex and hippocampal formation of the rats submitted to a physical exercise program on a treadmill during adolescence...

BACKGROUND: Regular engagement in physical activity can help youth control their weight during childhood while decreasing one's chances of developing chronic diseases (e.g., coronary heart disease, diabetes) throughout the lifespan. While numerous studies have explored physical activity participation and weight status among typically developing children, few epidemiological studies utilizing nationally representative data has focused on children with chronic health problems, illness, or disabilities (CHID)...

Autism spectrum disorder (ASD) gradually develops predominantly neurodevelopmental disorders, which are socially diagnosed in early childhood. Though the etiopathology of ASD is not clear, immune alteration has been suggested as autism's pathophysiological mechanism. Previous studies found that several cytokines and transcription factor activation pathways were significantly increased in ASD. IL-9 has been confirmed to play a significant role in the central nervous system (CNS). The aim of the present study was to investigate the understudied role of pro- and anti-inflammatory cytokines and the JAK-STAT signaling pathway in ASD...

Duchenne Muscular Dystrophy (DMD) is the most frequent muscular dystrophy in childhood, with a worldwide incidence of one in 5000 live male births. It is due to mutations in the dystrophin gene leading to absence of full-length dystrophin protein. Central nervous system involvement is well-known in Duchenne Muscular Dystrophy. The multiple dystrophin isoforms expressed in brain have important roles in cerebral development and functioning. The association of Duchenne Muscular Dystrophy with seizures has been reported, and there is a higher prevalence of epilepsy in Duchenne Muscular Dystrophy patients (between 6...

Child development in low and middle income countries (LMIC) is compromised by multiple risk factors. Reducing children's exposure to harmful events is essential for early childhood development (ECD). In particular, preventing violence against children - a highly prevalent risk factor that negatively affects optimal child development - should be an intervention priority. We used the Child Health and Nutrition Initiative (CHNRI) method for the setting of research priorities in integrated Early Childhood Development and violence prevention programs (ECD+)...

Neuroblastoma is a cancer of the neural crest almost exclusively seen in childhood. While children with single, small primary tumors are often cured with surgery alone, the 65% of children with neuroblastoma whose disease has metastasized have less than a 50% chance of surviving five years after diagnosis. Innovative pharmacological strategies are critically needed for these children. Efforts to identify novel targets that afford ablation of neuroblastoma with minimal toxicity to normal tissues are underway...

Neuroblastoma is a brain malignancy of childhood and accounts for 7-10% of childhood cancers, leading to approximately 15% of pediatric cancer deaths. MicroRNAs (miRNAs) are a family of short (about 18-25 nucleotides), noncoding and single stranded endogenous RNAs, which complementarily bind to the 3' untranslated regions of their target genes. Recently, glutamine metabolism has been recognized as an important nutrition source for tumor cells, and hence targeting glutamine metabolism could benefit to development of anti-cancer agents...
