Filter by:This study is a prospective, observational, single-center study to assess the correlation between rs-fMRI measures and clinical measures of standard MRI, NIRS, EEG and clinical scores. The target population was neonates with HIE referred to MRI after hypothermia treatment, which was initiated within 6 hours of birth, continued for 72 hours and followed by a slow rewarming period of 6-12 hours. A one-year clinical and imaging follow-up is planned. As the aim of the present study is to assess the predictiveness of the outcome one year after the HIE event, no follow-up is planned.
In this study, the objective is to compare neonatal cerebral oxygenation and electrical activity within 3 days after birth across different altitude areas using non-invasive methods, specifically near infrared spectroscopy (NIRS) and amplitude-integrated electroencephalography (aEEG), and establish reference value for each altitude level.
This is a multicenter prospective observational study that aims to determine the natural history of patients with early diagnosis (within 6 hours of life) of mild hipoxic ischemic encephalopaty (HIE), who are not candidates for treatment with therapeutic hypothermia. The goal of this study is to learn about the early neurological outcome in babies with mild encephalopathy, as recent studies have shown how there is an increased risk of brain damage with a high incidence of resonance magnetic nuclear (RMN) anomalies and possible neurodevelopmental complications including learning or neuropsychological disorders, epilepsy, visual and sensory deficits. The main question aimed to answer is the identification of early possible predictive factors for an unfavorable outcome in order to undertake early rehabilitation programs and for the future planning of trials on early neuroprotection in the investigated population. Babies with early diagnosis (within 6h of life) of mild grade HIE not candidate for hypothermic treatment are subjected to clinical and instrumental assessments during the neonatal period: - neurological objective exam according to the modified "Sarnat" score, Thompson score and Hammersmith Neonatal Neurological Examination (HINE) within 6 hours of life, 24 hours of life and before resignation; - an Amplitude Electroencephalogram (aEEG) study within 6 hours of life, for 6 hours; - cerebral ultrasound within 6 hours of life, in the third and seventh day of life; - a brain magnetic resonance imaging study between the seventh and 14th day of life; - an Electroencephalogram (EEG) evaluation within 7 days. After resignation, all patients will be included in a minimum duration follow-up program of 12 months, with assessments at 3rd, 6th and 12th month of age: - Hammersmith Neonatal Neurological Examination (HINE) and evaluation of the General Movements; - evaluation of psychomotor development through Griffiths/Bayley III scales at the 12th month; - EEG evaluation at the 6th and 12th month.
The goal of this trial is to learn about the effect of PRAX-222 in pediatric participants with early onset SCN2A developmental and epileptic encephalopathy (DEE), aged 2 to 18 years.
This study aims to investigate whether a live stream video between the on-call neurologist and the emergency medical services is feasible.
Hepatic encephalopathy (HE) is one of the most serious complications of end-stage liver disease and an independent predictor of death in patients with liver cirrhosis. Recurrent hepatic encephalopathy is defined as recurrent hepatic encephalopathy after rifaximin combined with lactulose treatment. This project designs a prospective, multicenter cohort study on the treatment of recurrent hepatic encephalopathy with fecal microbiota transplantation, carries out the comparison of fecal microbiota transplantation with different amounts of bacteria, and the dynamic sequencing of the macro genome of the recipient's stool, compares the effectiveness and safety of fecal microbiota transplantation with different amounts of bacteria in the treatment of recurrent hepatic encephalopathy, and explores the internal mechanism of different effects, providing a new idea for the treatment of recurrent HE in clinical practice.
If intracranial pressure can be measured non-invasively using single-channel EEG, clinicians will be able to easily monitor changes in intracranial pressure in patients with brain diseases in the clinical setting. Therefore, a more efficient treatment plan can be established and the prognosis of patients with brain disease can be expected to improve in the long term.
This pilot study aims to assess if participants that meet the criteria for a TES diagnosis have a specific tau deposition profile on PET scanning using the PET tau binding ligand - [18F] PI-2620. It is hoped this study will highlight potential diagnostic tests of TES diagnosis, the in-life correlate of CTE.
This is an observational study that will test the clinical significance of speech features in patients with cirrhosis. It aims to assess if speech is associated with cognitive function at baseline, if speech predicts changes in cognition, and if speech predicts future events of hepatic encephalopathy (cirrhosis-related confusion), as well as to assess the dynamics of speech over time, especially with episodes of overt hepatic encephalopathy (OHE) and treatment interventions.
Background the research proposed herein is in line with the Swedish Research Council's current focus on International collaborations and postdoctoral work abroad. In this case the child brain and translational and clinical infant brain research. Neonatal hypoxic ischemic encephalopathy in term infants constitutes a serious health problem, not the least due to its often life-long consequences in the form of cerebral palsy and other forms of brain dysfunction. An estimated 3-5 of every 1000 live term births are affected, a quarter of which with severe symptoms; 10-30% of the affected children do not survive, 30% suffer life-long disabilities. The incidence may be 10-fold higher in the developing world. In Sweden, an estimated 200 children are born each year with hypoxic ischemic asphyxia or oxygen deprivation during delivery of a severity necessitating treatment, in order to reduce future handicap. Not only the brain, but also other organs, such as the heart, liver or kidney can be damaged by hypoxic ischemia. In clinical trials, proof has been obtained that cooling can have positive effects counteracting brain injury induced by oxygen deprivation (asphyxia). Recent research suggests that cooling may also have a positive effect in stroke during the pre-treatment/transportation to hospital phase. PCM. A material with phase change properties (PCM) can be a chemical element, a solution or a substance with high melting energy. It melts/solidifies at a precise temperature and can store considerable amounts of energy (heat) before changing from one phase to another. The study group have used elements or solutions that change between solid and fluid phases within a narrow temperature interval. The most common use of PCM today is for energy storage, accomplished by having the PCM change between solid and fluid phases. Phase changes that include other PCMs, high temperatures and/or gas phases are less useful in medical applications due to the need of either large volumes in a low pressure setting or smaller amounts in a high pressure setting, increasing the risk for mistakes or secondary injury to medical staff or patients. For the clinical purposes of hypothermic treatment described here, the Glauber salt-based PCM in a mattress form developed by the applicant has near ideal properties; it is completely safe, does not cause over-cooling, can be reused many times, eliminates cooling fluctuations, is easy to handle and biodegradable.
