Filter by:The low-flow malformations include venous and lymphatic malformations. The malformation often affects the skin and can extend deep to the muscles and bone, as well as to deep organs. Children with low-flow vascular malformation and their family have difficulty living with their illness and have an impact on their life quality. In this context, the aim of the study is to develope life quality test for the children between 11 to 15 years old.
The purpose of this study was to investigate whether the balanced fluids therapy change plasma osmolality in neurosurgical procedures due to brain tumors, meningeomas and arterio-venous malformation.
To assess the indications and diagnostic efficiency of whole genome sequencing (WGS) in pediatric patients with unexplained intellectual disability/developmental delay, multiple congenital abnormalities and other rare and undiagnosed diseases
Prematurely born children are at higher risk of cognitive impairments and behavioral disorders than full-term children. There is growing evidence of significant volumetric and shape abnormalities in subcortical structures of premature neonates, which may be associated to negative long-term neurodevelopmental outcomes. The general objective is to look directly at the long-term neurodevelopmental implications of these neonatal subcortical structures abnormalities. Investigators propose to develop biomarkers of prematurity by comparing the morphological and diffusion properties of subcortical structures between preterm, with and without associated brain injuries, and full-term neonates using brain MRI. By combining subcortical morphological and diffusion properties, investigators hypothesize to be able to: (1) delineate specific correlative relationships between structures regionally and differentially affected by normal maturation and different patterns of white matter injury, and (2) improve the specificity of neuroimaging to predict neurodevelopmental outcomes earlier. The specific aims and general methodology are: 1) Build a new toolbox for neonatal subcortical structures analyses that combine a group lasso-based analysis of significant regions of shape changes, a structural correlation network analysis, a neonatal tractography, and tensor-based analysis on tracts; 2) Ascertain biomarkers of prematurity in neonates with different patterns of abnormalities using correlational and connectivity analysis within and between structures features; 3) Assess the predictive potential of subcortical imaging on neurodevelopmental outcomes by correlating neonatal imaging results with long-term neurodevelopmental scores at 9 and 18 months, and 6-8 years, follow-up. In each of these aims, investigators will use advanced neuroimaging analysis developed by their group and collaborator, including multivariate tensor-based morphometry and multivariate tract-based analysis. This application will provide the first complete subcortical network analysis in both term and preterm neonates. In the first study of its kind for prematurity, investigators will use sparse and multi-task learning to determine which of the biomarkers of prematurity at birth are the best predictors of long-term outcome. Once implemented, these methods will be available to compare subcortical structures for other pathologies in newborns and children.
The purpose of this prospective cohort study is to build a large platform that includes clinical information (prenatal diagnosis and postnatal follow-up data) and biological specimen banks of fetuses/infants with IUGR or congenital anomalies, which provide vital support and research foundation for accurate diagnosis, precision treatment and meticulous management.
Near infrared spectroscopy is a valuable tool to monitor cerebral oxygenation during intracranial interventions. However, it yields artificial results when the dye indocyanine green (ICG) is applied, which is routinely done for intraoperative angiography. The investigators examine, to what extent and which duration NIRS is disturbed following ICG application.
The human microbiota, a collection of microorganisms mostly settled in the gastrointestinal tract, plays a major role in the maintenance of the hosts' health and in development of disease as well. Exposure to different conditions early in life contributes to distinct "pioneer" bacterial communities, which shape the newborn infants' development and influence their later physiological, immunological and neurological homeostasis. Newborn infants with congenital malformations of the gastrointestinal tract (CMGIT), necrotizing enterocolitis (NEC), and spontaneous intestinal perforation (SIP) commonly require abdominal surgery and enterostomy. While intestinal microbiota has been extensively studied in infants with anatomically uninterrupted intestine, the knowledge of longitudinal intestinal colonization in this population is scarce. This is an exploratory, observational, and longitudinal prospective study, primarily aimed to determine longitudinally the colonization of the proximal remnant intestine, in newborn infants with enterostomy after surgery (three weeks) for CMGIT, NEC and SIP. The secondary aim is to explore the associations of the colonization with the mode of delivery, gestational age, postnatal age, duration of fasting, type of enteric feeding, antimicrobial therapy, H2-receptor antagonist therapy, and length of proximal remnant intestine.
This study aims to assess the feasibility to perform a fetoscopic prenatal repair of an open neural tube defect, and secondly to assess the maternal, fetal and neonatal outcomes.
In the stage of randomized controlled study, our purpose is to obtain the Intraoperative anticoagulation program supported by evidence-based medicine.
In the stage of registration study, our purpose is to find out the safety range of activated coagulation time level in cerebral aneurysm and arteriovenous malformations with hybrid operation.
