Neuraxial Labor Analgesia and Offspring Neurodevelopment

How perinatal factors affect the long-term development of children has always been an issue of much concern. This study is designed to explore the potential impact of maternal neuraxial labor analgesia exposure on offspring neurodevelopment.

Early Detection and Intervention in Developmental Delay / Behavioral Problems in Preschool Children - PLUSS

The PLUSS (Mental health, learning, development, collaboration around preschool children) is a collaborative project involving guardians, Jönköping County´s health care, preschools and social services. The project studies the implementation of a "One way in"-model that provides coordinated services to screen, evaluate and treat toddlers with behavioral problems. The project also provides parental interventions and education for preschool teachers. The study aims to investigate a) implementation of the PLUSS model, b) effectiveness of the model and the included parental training program on behavioral problem and their longitudinal development among preschool children, c) parental wellbeing and satisfaction. In the long term, the goal is to reduce mental health problems among children, adolescents and their families and to provide support for a functioning everyday life.

General Anesthesia/Surgical Exposure on White Matter Development in Children

International large-scale clinical studies have found that prolonged or repeated exposure to general anesthesia drugs in infancy and early childhood can lead to an increased risk of long-term neurodevelopmental abnormalities in children. The study of neurodevelopmental toxicity of general anesthesia drugs is of great social significance. We have established a rhesus monkey model to study the neurodevelopmental toxicity of general anesthetic drugs, the first time to make a preliminary exploration of the mechanism of myelin developmental toxicity of general anesthetic drugs. Several studies using magnetic resonance scanning found a positive correlation between the number of anesthesia exposures and the maturity of distant brain white matter development in juvenile non-human primates. Clinical evidence for myelin developmental toxicity induced by general anesthetic drugs needs to be collected by conducting multicenter and large-sample clinical studies. Earlier studies have either had low sample sizes, which do not allow for better control of confounding factors; or the study population has been limited to specific disease populations, and the results cannot be extrapolated to normal children. In view of this, based on the applicant's earlier study, this project proposes to recruit children who underwent general anesthesia surgery between 0-3 years of age and are now 12-15 years old; children who did not experience surgery between 0-3 years of age were matched by age-sex to serve as a control group. MRI will be used to assess their brain white matter development, to explore the correlation between anesthesia and anesthesia-related factors and brain white matter development and related neurobehavioral development, and to clarify the effects of anesthesia and surgery on children's brain white matter and related neuropsychological development.
