Filter by:The Shenzhen Birth Cohort Study was set up to investigate the effect of early life environmental exposures on short- and long-term health consequences in Shenzhen, China.
The objective of this study is to develop an automated, precise, quantitative assay for detecting atypical motor behavior and development in infants using data from wearable sensors and video recordings.
The purpose of this study is to analyze patterns in individuals with hnRNP (and other) genetic variants, including their neurological comorbidities, other medical problems and any treatment. The investigators will maintain an ongoing database of medical data that is otherwise being collected for routine medical care. The investigators will also collect data prospectively in the form of questionnaires, neuropsychological assessments, motor assessments, and electroencephalography to examine the landscape of deleterious variants in these genes.
The primary aim of this study is to compare the diagnostic accuracy of an iPad application (Play.Care assessment) with the current clinical "gold standard" diagnosis for diagnosis of Autism Spectrum Disorder (ASD) in children. Recent evidence has suggested that movement abnormalities are one of the early markers of ASD. However, current clinical diagnostic assessments fail to take this into account. Further, the current "gold standard" clinical tests take a number of hours to administer, require extensive clinical training and are subject to a certain level of subjectivity. Alternatively, by assessing a child's interaction with an iPad screen as they play, an objective measurement of movement can be obtained, which can aid in the diagnostic process. This study aims to recruit a total of 760 children (Typically Developing (TD), Other Neurodevelopmental Disorders (OND) and ASD groups) to assess the diagnostic accuracy of tablet game play in ASD. Children who have been diagnosed with ASD will perform the Play.Care assessment to assess if the tablet result matches their clinical diagnosis. Results from the clinical assessment and Play.Care assessment will then be compared to assess the sensitivity (the proportion of participants with ASD who test positive for ASD as a result of the Play.Care assessment) and specificity (the proportion of participants without ASD who test negatively for ASD as a result of the Play.Care assessment assessment) of the Play.Care assessment.
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 research study is to evaluate the feasibility in conducting advanced MRI sequences in a pediatric clinical setting. The study will be observational in nature, and will only evaluate the studies of pediatric patients who have already been prescribed an advanced MRI for clinical neurological purposes. The only difference for the subject in participating in this study is that the data and information about their scan can be used and disclosed for research purposes, i.e. understanding if the time of the scan, patient comfort, and quality of the data are feasible. Standard MRI's have been extremely beneficial in the diagnosis and assessment of disease, injury, and anomalies throughout the body. Adding advanced MRI sequences to the arsenal of current standard MRI sequences, as well as analyzing the clinical significance of the data, may improve the benefits of MRI in the future. Within this scope, the study will be looking at the following factors: 1. The total time of the scan, including: - Patient arrival time/lateness - Patient preparation time - Time scanner is being occupied - Patient compliance (is the patient continually stopping the study for breaks, fear, movement, etc.) 2. Patient dropout rate, including: - Change of mind - Cost of study is too much - Failure to finish the scan 3. Usability of data, including: - Movement artifact - Patient requiring re-scan for any reason The scan will consist of two to five advanced MRI sequences that will average between 7-15 minutes each, in addition to a routine 5 minute standard MRI sequence. The variability in the number of advanced sequences depends on the prescription and patient history. All sequences are performed using a 1.5 Tesla Siemens MRI scanner at Westwood Open MRI, a 3 Tesla GE scanner at Tower Saint John's Imaging, or a 3 Tesla Siemens MRI scanner at Resolution Imaging. All scanners are FDA-approved.
Locomotor, transport and information functions in human body systems are carried out by active media in autowave regimes! Any living organism is a (micro-macro-mega) hierarchy of autowave subsystems-an ensemble of loosely coupled subsystems of a simpler structure. From the highest levels of the hierarchy, Autowave Codes-Signals arrive, which determine the transitions of subsystems from one autowave regime to another Autowave interaction (of Complex Coherent Action). Autowave interaction is a process associated with the evolution and interaction of spatial and wave structures in the active media of the organism. Chaos in organism functioning tells about health. Periodicity - Autowave reverberator may presage a disease - Autism Spectrum Disorder; Chaotic nature of oscillations in active media of physiological systems is more optimal for their vital functions than periodic one. Firstly, systems that function in chaotic regimes, can re-arrange themselves faster and easier in case of change of environmental conditions, i.e. the so called adaptive control is more easily implemented in them. Secondly, "spreading" of oscillations strength along comparatively wide frequency band takes place in chaotic regime. When an organism is young and healthy, physiological systems show the elements of chaotic behavior, i.e. irregularity and chaotic dynamics are the extremely important characteristics of health. Decrease in changeability and appearance of stable periodicity of Autowave reverberator are often connected with Autism. The main purpose is to study brain plasticity (the changes that occur in the brain through Autowave reverberator) in children with autism. Research suggests that during development, the brains of children may change in response to their Autowave reverberator differently than the brains of typically developing individuals. Investigators want to understand why and how this difference may contribute to the symptoms of autism spectrum disorder (ASD). In this study, the investigators will be examining the effects of non-invasive neuromodulation SQUED™ series 28.1 home-use for Treatment of Autowave reverberator of Autism.

Common mental disorders (CMD) such as Depression, contributes significantly to the global burden of disease. Fetal exposure to adverse intrauterine environment mediated by life course factors can enhance risk of non-communicable disease in later life. Maternal micronutrients such as Vitamin B12 and folate play an important role in early fetal development through their effect on one carbon metabolism. Vitamin B12 deficiency is common in Indian women; however guidelines recommend only iron, folic acid supplementation during pregnancy. This study aims to investigate effects of maternal B12, folate during pregnancy on mental health and neurocognitive outcomes in offspring during adulthood. The Pune Maternal Nutrition Study(PMNS) birth-cohort(n=762) was established in 1993 at the Diabetes Unit of KEM Hospital Pune with well characterized serial data and archived biological samples. The subjects of the cohort are now in age range of 20-22 years and this provides an opportunity to examine the proposed objectives. Key objectives: To examine the specific association between maternal vitaminB12, folate, homocysteine levels at 18 & 28 weeks of gestation and risk for CMD, neurocognitive outcomes. Examine the causality of this association by Mendelian randomisation using genetic determinants of vitamin B12 and homocysteine. Design and analysis: Consenting members of the birth cohort of PMNS (n=690) will be recruited after ethics approval. Following cross-sectional outcome measures will be measured Neurocognitive functions: using standardized neuropsychological battery Brain imaging for Structural and functional magnetic resonance imaging (MRI). Temperament-character dimensions (TCI):140 item short TCI-R. Structured clinical interview for CMD, Diet, physical activity, High-risk behaviors, Early life stress. Serum Brain Derived Neurotrophic factor (BDNF), Insulin like growth factor (IGF-1) from serum archived at 6,12 & 18 years. Longitudinal methods and multivariate regression analysis would be used to investigate the hypothesized associations. Path analysis will be used to generate pathways of evolution of the abnormalities. Causality of the associations will be assessed by Mendelian randomization analysis (triangulation and instrumental variable analysis) using maternal genetic determinants of vitamin B12 and homocysteine
The prospective multicenter study GD-Brain provides a better knowledge on the basis of neurological impairment in children born to mothers with gestational diabetes (GDM). GDM modifies placental structure and affect materno-fetal nutrient transfer. Docosahexaenoic acid (DHA) play an important role on neurodevelopment, and it is reduced in venous cord blood of newborns born to GDM. In previous studies, we have already demonstrated impaired DHA fetal levels not only using label fatty acids with stable isotopes administrated to pregnant women, but also in observational studies in GDM as the prevention of obesity study (PREOBE study) in Granada and other similar study in Murcia. The impaired cord DHA levels were associated to disturbed neurodevelopment in these children during the first year of life. However, it is uncertain the mechanisms underlying this impaired materno-fetal DHA transfer and implications for later life. The recent publication in Nature Journal of a selective transmembrane carrier for DHA in brain named "major facilitator superfamily domain 2a" (MFSD2a) open new expectations. We detected disturbed MFSD2a levels in placentas from GDM which could be due to structural problems in this organ; inflammation, oxidation and metabolic changes related to diabetes might affect MFSD2a activity. Moreover, it is difficult to know whether disturbed MFSD2a levels in placenta may also indicate altered levels of this carrier in the brain from children born to GDM mothers, which could contribute to neurodevelopment impairment in these subjects. Recent studies also indicate that obesity alters the biosynthesis of eicosanoids derived from DHA, with a decrease of protectins and resolvin of D-series, which have powerful anti-inflammatory properties. The main aim of this study is to analyse potential differences on neurodevelopment, and brain structure and functioning, in children 8 years old born to GDM respect to those born to healthy normoweight mothers, as well as to identify early biomarkers consistently related to neurodevelopment from early stages of life.
The advancement in life-saving technologies and clinical expertise in the care of extremely premature infants, have resulted in the development of large neonatal intensive care units (NICU). It has been suggested that reconstruction of megaunits of neonatal intensive care to smaller care units with specific patient population and clinical team providers will be essential to maintain optimal teamwork, quality of care and patient outcome. Despite the growing knowledge around the need for reconstruction of large NICUs to smaller units of care, there is no evidence regarding the safety and efficacy of microsystem model of care on the key aspects of health care. At the McMaster Children's Hospital (MCH), we planned a change from standard model of care to the microsystem model of care and therefore we aimed to prospectively assess the effect of this organizational change on the variable aspects of health care. A working group met weekly to formulate the implementation planning, to review the adaptation and adjustment process and to ascertain the quality of implementation following the initiation of the microsystem model. The study was retrospectively registered.
