Active clinical trials for "Brain Diseases"

The post-operative delirium picture is a serious and common complication seen after any major surgery, including hepatic resection. Patients who will be planned to undergo donor hepatectomy for liver transplantation will be included in the study. Basic clinical and demographic information of patients undergoes donor hepatectomy will be recorded before surgery. The anatomical parameters such as liver volume, medications performed during the surgery, complications, bleeding amounts, fluids given, blood and blood products, vital signs during surgery, fluid balance, duration of surgery, recovery length at post-operative period, complications after surgery, approaches to complications, analgesics and other medications used, hemogram and other biochemical parameters (electrolytes, albumin, liver frontier tests, etc.), weight status, vital signs, duration of intensive care, post-operative VAS scores, drainage and information such as length of stay, length of hospital stay, the healing time of the wound will also be recorded. During the hospitalization, the delirium status of the patients will be evaluated with a delirium evaluation scale by consultant doctor. Blood will be taken for the measurement of S100β, NSE, and GFAP levels one day before donor hepatectomy and following day of hepatectomy, 3rd day, and 7th day in the post-operative period. The plasma of the blood taken will be separated and stored at -80 0C until working. Laboratory values are taken from the patients before the operation will be recorded over the system. The relationship between the results obtained and the delirium evaluation scores performed on the days followed will be evaluated. This study aims to analyze the delirium incidence and post-operative early S100β, NSE, and GFAP levels within the first week following the hepatectomy performed in live donors for liver transplantation.

Immune effectors cells-associated neurotoxicity syndrome (ICANS) is one of the most clearly defined acute toxicities after CAR-T cells infusion. The investigators conducted a prospective cohort study of all patients who received CAR T cell infusions on the hematology department from Montpellier University Medical Center. Each patient was assessed between the 6th and 8th day after infusion by a neurological clinical examination, an electroencephalogram, and a brain MRI. The aim of the studies is to describe the EEG pattern associated with ICANS.

Some ICU ventilated patients might present with large tidal volume despite very low or inexistant presser support. Patient-Self Inflicted Lung Injury (P-SILI) might appear related with large alveolar stretch an distension. Two clinical presentations are observed: patients with or without respiratory distress signs such as supra-clavicular depression and thoracic-abdominal asynchronies. The aim of this study is to compare the pulmonary physio(-patho)logical parameters of these two types of patients (eupneic or with respiratory distress signs), and presenting important TV in spite of a minimal adjustment of the ventilatory support, except for Acute Respiratory Distress Syndrome (ARDS).

Minimal hepatic encephalopathy (MHE) can have a far-reaching impact on quality and ability to function in daily life and may progress to overt Hepatic Encephalopathy. Patients with MHE were missed in clinical follow up and are more exposure to work accident. The aim of the present study was to assess the effects of oral supplementation of antioxidant and zinc gluconate Versus Lactulose inTruck driver cirrhotic patients with MHE.

This study aims to determine the effect of therapeutic hypothermia on reducing AKI in term and late-preterm infants with hypoxic ischemic encephalopathy as estimated by measurment of serum(s) neutrophil gelatinase-associated lipocalin(NGAL) and serum (s) cystatin-C.

1 in 1000 babies are born suffering from a lack of oxygen. This is known as hypoxic ischemic encephalopathy (HIE). Infants with this condition can suffer multiple organ problems. In particular it can affect how their hearts pump blood around their body thus leading to a poor blood supply to parts of their body such as the brain. This is known as circulatory failure and can contribute to poor long term outcomes such as cerebral palsy. To try and prevent brain damage these infants are treated with total body cooling, however this treatment can further effect how babies pump blood around the body, but also how drugs which may be used by in this condition are processed. In order to assess and treat this condition doctors need to be able to accurately measure the blood supply in an infant. However there is no agreement on how best to do this. This makes decisions about when to treat an infant difficult. Sometimes doctors may want to use drugs such as dobutamine or adrenaline but these drugs are unlicensed in babies. This study proposes to observe the way babies circulatory problems are treated in babies with HIE the in the first four days of life. In addition the study will look are two new measurements of a babies blood supply to see if they are a better measure of when an infant needs treatment. This will involve an ultrasound scan of the heart and measurement of the baby's oxygen levels from a probe placed on their hand. The study will also look at how the drug dobutamine is processed by babies. This will be done from two small extra blood tests. The aim of the study is to help clinicians refine the identification and treatment of circulatory failure in babies with HIE.

N-acetylaspartate (NAA) is a surrogate neuronal marker and its proton magnetic resonance spectroscopy (1H MRS) signal decreases with increasing neuronal mortality associated with cerebral hypoxia-ischaemia. The MRS lactate (Lac)/NAA peak-area ratio increases during and after severe cerebral hypoxia-ischaemia reflecting mitochondrial injury and impaired oxidative phosphorylation. Aims: (1) To establish normative ranges for thalamic 1H MRS NAA concentration and Lac/NAA in healthy newborn infants (2) To examine the accuracies of thalamic 1H MRS NAA concentration and Lac/NAA for predicting adverse neurodevelopmental outcome in neonatal encephalopathy (NE) Design: Prospective observational study Methods: Year 1: Following 1H MRS methodology optimisation 40 healthy control infants will be recruited to collect normative data. Year 2 to 3: 115 infants with NE, undergoing therapeutic hypothermia will be recruited. MRS will be performed aged less than 4 days and 7 to 14 days and thalamic NAA levels and Lac/NAA will be quantified; Qualitative interviews to evaluate parental understanding of this biomarker. Year 4, 5: Outcome assessment by BSID III at 18 months. Outcomes: Mean thalamic NAA levels and Lac/NAA and appropriate confidence intervals in normal infants, and thalamic NAA levels and Lac/NAA in infants with NE according to neurodevelopmental outcome. Areas under curves for thalamic NAA and Lac/NAA will be examined separately for early & late MRS. Accuracy of early MRS will inform utility of this investigation in decisions about withdrawal of life support; late MRS will inform about efficacy as a surrogate end point in clinical trials. Qualitative interviews will be thematically analysed and reported.

The primary objective of HOPE is to improve the accuracy of outcome prediction in anoxic-ischemic encephalopathy following cardiac arrest by bringing under close scrutiny some of the existing methods used for this purpose (e.g. somato-sensory evoked potentials). HOPE is the first multicenter prospective cohort study on coma prognosis to control for the effect of a possible self-fulfilling prophecy at the ICU and to cover the acute and neurorehabilitation phases with a long-term follow-up longer than the usual three or six months.
