Correlations between serum BDNF levels and neurodevelopmental outcomes in infants of mothers with gestational diabetes.

Background: Diabetes during pregnancy is associated with an increased risk of foetal and neonatal complications and long-term complications in the offspring. Brain-derived neurotrophic factor (BDNF), a neurotrophin that has a crucial role in neurogenesis modulation and neural pathway maturation during neurodevelopment, may have a role in protecting neurons against injury and diseases by modulating glucose metabolism. The aim of this study was to investigate the possible relationship between the serum BDNF levels of infants of mothers with gestational diabetes (IMGD) and neurodevelopmental outcomes of the children after birth.

[Space-Time Estimations and Mapping of PM Fine Particulates Based on Multi-source Data].

PM pollution in China has become an extreme environmental and social problem and has generated widespread public concern. We estimate ground-level PM from satellite-derived aerosol optical depth (AOD), topography data, meteorological data, and pollutant emissions using a new technique, Bayesian maximum entropy (BME) combined with geographically weighted regression (GWR), to evaluate the spatial and temporal characteristics of PM exposure in an eastern region of China in winter. The overall 10-fold cross-validation is 0.

Identification of an association between genomic hypomethylation of FCGR2A and susceptibility to Kawasaki disease and intravenous immunoglobulin resistance by DNA methylation array.

Objective: Kawasaki disease (KD) is characterized by systemic vasculitis, and it is the most common acquired heart disease in children. However, the etiology and immunopathogenesis of KD are still unclear. A genome-wide association study (GWAS) identified polymorphisms in CD40, BLK, and FCGR2A as the susceptibility genes for KD.

Periventricular echogenicity is related to delayed neurodevelopment of preterm infants.

Periventricular leukomalacia (PVL) is one of the most commonly seen neuropathologic lesions and is related to many neurodevelopmental handicaps in premature infants. Periventricular echogenicities (PVE) are considered to be at the milder end of the spectrum of PVL, and thus might affect the neurodevelopment of the preterm infants as well. In this retrospective cohort study medical records of 257 preterm infants who were discharged from our neonatal intensive care unit (NICU) during October 1996 to August 2000 were reviewed.
