Sepsis-associated encephalopathy (SAE), is one of the most common organ dysfunction during the acute phase in sepsis and septic shock. Electroencephalogram (EEG) and auditory evoked potentials (AEPs), which reflect different aspects of brain function, are the most commonly used neurophysiological indices to detect acute brain dysfunction in critically ill patients including sepsis and septic shock. AEPs show the systemic responsiveness of the central nervous to auditory stimuli, so they can be considered a direct measure of brain responsiveness. Mismatch negativity (MMN) is a change-specific component of ERPs, which elicited by a deviant stimulus occurring in a sequence of repetitive stimuli. This component is thought to represent the automatic and unconscious detection of acoustic changes which requires good perceptual discriminative capacity and iconic memory. The peaks of MMN appear at 100 ~ 250 ms from deviant stimulus onset; with increasing magnitude of stimulus change, the peak latency of MMN was shortened and the amplitude increased. Since MMN can be elicited even in the absence of attention, subjects do not need to actively participate. The MMN has been extensively demonstrated to be used in the prediction of awakening in comatose patients for various reasons, and also has been reported to predict awakening in deeply sedated critically ill patients recently. However, it remains unclear whether SAE affects MMN in amplitude and latency that reflects cognitive processing of the auditory information. Patients with sepsis and septic shock who met the inclusion criteria were screened daily on the CAM-ICU scale, and those with positive CAM-ICU were diagnosed with SAE.All patients were tested for event-evoked potentials on Day 1 and Day 3 after inclusion and were followed up to Day 28 after discharge. The investigators intend to observe the dynamic change of MMN amplitude and latency between SAE and non-SAE groups. Logic regression analysis was used to determine whether the change of MMN was a predictor of SAE.
TReatment for ImmUne Mediated PathopHysiology (TRIUMPH) is a multi-center, three arm, randomized, controlled trial of immunosuppressive therapy for children with acute liver failure. The study will determine if suppressing inflammatory responses with either corticosteroids or equine anti-thymocyte globulin therapy improves survival for children with this rare, life-threatening condition.
This is a global study to compare the effects of AXA1665, an orally active mixture of amino acids, compared to placebo, on cognitive and physical function, as well as the safety and tolerability of AXA1665.
Babies who have brain injury also frequently have involvement of their kidneys, lung and heart. Although clinical care in the neonatal period is well defined there are few guidelines and evidence for developmental, heart and kidney followup in childhood. The investigators aim to develop and implement guidelines for health care workers and families on Followup after Neonatal Brain Injury. Inflammation is an important factor in brain injury of newborns and also affects their heart lungs and other parts of their body. The investigators will use tests from the newborn period to predict outcome and help parents with planning health needs for their baby rather than waiting until any issues arise later on. By understanding inflammation the investigators can find methods to decrease the negative effects and improve outcomes in the future for babies and families.
Minimal hepatic encephalopathy (MHE) is a subclinical cognitive impairment and represents the mildest type of hepatic encephalopathy (HE). Portal hypertension is the main complication of cirrhosis and is responsible of severe complications such as HE. The consequence of portal hypertension is the formation of the spontaneous portosystemic shunts (SPSS). The relationship between the SPSS and their characteristics and the prevalence of MHE in patient with cirrhosis is poorly known. The main objective of this study is to evaluate the MHE in patients with cirrhosis and portal hypertension.
Mitochondrial DNA (mtDNA) depletion syndromes (MDS) are a genetically and clinically heterogeneous group of autosomal recessive disorders that are characterized by a severe reduction in mtDNA content leading to impaired energy production in affected tissues and organs. MDS are due to defects in mtDNA maintenance caused by mutations in nuclear genes that function in either mitochondrial nucleotide synthesis. MDS are phenotypically heterogeneous and usually classified as myopathic, encephalomyopathic, hepatocerebral or neurogastrointestinal. No efficacious therapy is available for any of these disorders. Affected individuals should have a comprehensive evaluation to assess the degree of involvement of different systems. Treatment is directed mainly toward providing symptomatic management. No treatment for MDS. Clinical trials studies and in vitro/in vivo research studies showed that the enhancement of the salvage pathway by increasing the availability of deoxyribonucleosides needed for each specific genetic defect prevents mtDNA depletion. Early recognition and immediate therapy to restore mitochondrial function could potentially improve clinical course. Confirming the benefit of deoxynucleosides as a safe and potentially efficacious therapy, will lead to the availability of the first specific and effective treatment for Mitochondria Depletion Disorders. In this phase II Trial a mix of Deoxynucleosides Pyrimidine (Deoxycytidine dC and Deoxythymidine dT) will be used as early treatment of MDS. The dose used has been already used in other clinical trials, and appears to effective and well-tolerated. The subjects included are children (0-18Y), with positive MDS diagnosis and express mutations in one of the following genes: POLG, C10orf2, RRM2B, MPV17, SUCLA2, SUCLG1, FBXL4. Subjects with MDS expressing neurological phenotypes dysfunction.
Electrical activity emerges in the third trimester of pregnancy, plays an important role in the construction of cortical maps, and is impaired in patients with severe early epileptic encephalopathies (EOEE). EOEE are rare and severe epileptic syndromes characterized by epilepsy that begins within the first three months of life and is associated with rapid deterioration of motor, cognitive and behavioral skills. There is a genetic basis for the EOEE. Together with other laboratories, the investigators have identified de novo pathogenic variants in the KCNQ2 gene encoding the Kv7.2 subunit of the Kv7 / M potassium channel, a channel known to control neuronal excitability in the brain and spinal cord. via the current M (IM). Pathogenic variants of the KCNQ2 gene represent the main cause of EOEE and the term KCNQ2-related epileptic encephalopathy (KCNQ2-REE) is now used to define this condition. KCNQ2-REE patients have a remarkably homogeneous phenotype at the start, with epilepsy that begins in the first days after birth, seizures that result in tonic muscle spasms that last from 1 to 10 seconds, and an interictal EEG called "suppression-burst". "That is, paroxysmal bursts of activity interspersed with periods of electrical silence. In this group, more than 50% of the patients present a remission of the epilepsy and a quasi-normalization of the EEG which can occur a few weeks to several months after the onset of the seizures. Despite this positive evolution in terms of seizures, the developmental progression is abnormal and the phenotype is severe with an absence of language, autistic behavior and a subsequent development of motor disorders such as diplegia, spasticity, ataxia or dystonia. The ambition of this project is to increase knowledge of epileptic encephalopathies linked to KCNQ2 at the clinical and molecular levels, to decipher the pathophysiological mechanisms and to propose therapeutic strategies. This project aims to better describe the clinical, EEG, imaging, developmental and long-term follow-up characteristics of patients carrying the KCNQ2 mutation identified in the laboratory.
Children with acquired brain injury (ABI) often struggle with complex impairments, including cognitive (such as memory and attention), social, emotional and behavioral challenges. There is a lack of evidence-based knowledge about rehabilitation for children with ABI in the chronic phase. The current study, the CICI Study, is a randomized controlled trial (RCT) directed towards children with ABI and their families in the chronic phase. The study will be conducted in close collaboration with schools and local health care providers. The CICI Study focuses on the child's and parents' individually identified target outcome areas and rehabilitation goals. The intervention aims to enhance everyday functioning in the home and school environment by attaining rehabilitation goals in areas noted as challenging by the participants. The efficacy of the CICI-intervention will be measured in terms of goal attainment, burden of brain injury related symptoms, parenting self-efficacy, unmet health care needs, as well as several aspects of child, parent and family functioning.
