Filter by:Epilepsy is a chronic condition that requires consistent follow-up aimed at seizure control, surveillance of comorbidities, monitoring of antiepileptic drugs (AED) levels and side effects. Patients may encounter difficulties to be assessed adequately and the disease burden is increased by the need for travelling across the country for medical consultations. Driving restrictions are a further limit to access specialized Centers able to provide an integrated approach focused on patient needs. Telemedicine (TM) offers an invaluable support to patient follow-up, joining the sparse distribution of patients in the country with the prompt availability of a team of experts. The project assesses, through a randomized controlled trial, the non-inferiority of TM in monitoring seizure control compared to usual (face-to-face) care. This approach, coupled with a new self home-sampling method for the measurement of AED levels, will reduce health care costs and simplify patients management.
It is planned to integrate various services based on computer vision technologies for analysis of the certain type of x-ray study into Moscow Unified Radiological Information Service (hereinafter referred to as URIS). As a result of using computer vision-based services, it is expected: 1. Reducing the number of false negative and false positive diagnoses; 2. Reducing the time between conducting a study and obtaining a report by the referring physician; 3. Increasing the average number of radiology reports provided by a radiologist per shift.
The study will evaluate the safety and feasibility of near infrared therapy as an intervention for patients with refractory depression, anxiety, neurodegenerative disease, and traumatic brain injury.
Neurocognitive impairment is frequently observed in pediatric patients with meningoencephalitis (ME) and sepsis-associated encephalopathy (SAE) which represent two relevant central nervous system (CNS) diseases in pediatric patients. It is uncertain, if the the origin of the disease, located primarily in the CNS of patients with ME or secondarily in patients with SAE in the course of sepsis, is of importance for the severity of injury to the brain. Prospective clinical studies combining clinical and laboratory examinations including specific biomarkers of neuroaxonal injury were not performed in a comparative study. Biomarkers of neuroaxonal injury are therefore not only of great interest to detect and monitor neurocognitive impairment but also to quantify the severity of brain injury in patients with ME and SAE.
This study is a multicenter, double blind, randomized, placebo-controlled study to evaluate the safety, tolerability and immunogenicity of different doses, regimens and combinations of Tau targeted vaccines in participants with early Alzheimer's Disease.
The study aims to identify factors that predict the medium and long-term outcome of patients with disorders of consciousness (DOC) undergoing early neurological rehabilitation. In this prospective, observational study, 130 DOC patients are going to be included (36 months). At study entry, different routine data, disease severity and functional status are documented for each patient. In addition, MRI, EEG and evoked potentials are measured within the first week. The level of consciousness is recorded with the Coma-Recovery-Scale-Revised and serves as the primary outcome parameter. Complications, comorbidities, functional status and leve of consciousness are assessed weekly. After eight weeks, the measurement of the MRI, the EEG and the evoked potentials are repeated. After 3, 6 and 12 months, the Glasgow Outcome Scale-Revised is used to followed up the current status of the patients.
Hepatic Encephaopathy is a common complication occurring in patients with Liver cirrhosis. Patients usually develop mild confusion, sleep disturbance or obtundation. It occurs due to accumulation of excess ammonia in the brain, as the liver is unable to metabolize the ammonia. The common gold standard treatment recommended for patients with Hepatic Encephalopathy is Lactulose syrup. This is a non absorbable sugar, often combined with an antibiotic called Rifaxamine to treat this condition. Polyethylene glycol is in a class of medications called osmotic laxatives which works by causing water to be retained with the stool. PEG and lactulose, when used together, result in faster resolution of symptoms suggesting that PEG may be superior to standard lactulose therapy in these patients. Non-absorbable sugars like lactulose are associated with non-serious (mainly gastrointestinal) adverse events like diarrhea and bloating Hence, due to the side effect profile, newer drugs continue to be tested for treatment of Hepatic Encephalopathy. The aim of this research project is to compare the effect of PEG versus lactulose for treatment of HE in patients with liver cirrhosis. The investigators want to compare the resolution of HE as the main outcome. In addition, they will compare length of stay, non-serious (mainly gastrointestinal) adverse events, and 3 months outcome. The investigators hypothesize that rapid purgation of the gut using PEG may resolve HE more effectively than lactulose.
Hypoxic Ischemic Encephalopathy is also known as 'birth asphyxia related brain injury' and happens when the brain does not receive enough oxygen or blood flow around the time of birth. Birth asphyxia related brain injury is the most common cause of death and neurodisability in term babies. Cooling therapy has substantially improved the outcomes of babies with HIE. However, unacceptably high rate of adverse outcomes are still seen in cooled babies with HIE. The EDEN trial is a 2 arm randomised control trial and aims to examine the physiological effects of Darbepoetin alfa (Darbe) therapy on proton magnetic resonance spectroscopy thalamic N-acetylaspartate (NAA) level in babies with neonatal encephalopathy undergoing cooling therapy. A total of 150 babies with neonatal encephalopathy will be recruited from the participating sites in UK over a 24 month period. The babies will be randomly allocated to darbepoetin or usual care. MR imaging and spectroscopy will be performed at 1 to 2 weeks of age to examine the brain injury. Neurodevelopmental outcomes will be assessed at 18 months of age.
Time is an important function that permeates our everyday activities but it has been so far significantly under-investigated in neurological patients. For instance, it is known that right brain damaged (RBD) patients with spatial attentional deficit (neglect) are impaired in both the ability to estimate the duration of an event (Time Estimation), showing a time underestimation, and the ability of mentally moving in past and future time (Mental Time Travelling), showing a deficit in processing future events when they are projected in the past. After a leftward shift of spatial attention induced by prismatic adaptation (PA), both the underestimation and the ability to travel in time ameliorate. However, less is known about these abilities in left brain damaged (LBD) patients. Aims of this study are to investigate: i) the performance (in terms of accuracy and reaction times) of LBD and RBD patients on Mental Time Travelling; ii) the correlation between Mental Time Travelling and Time Estimation abilities; iii) the efficacy of a single session of PA inducing a leftward (L-PA) and a rightward (R-PA) attentional shift on Mental Time Travelling and Time Estimation abilities. A group of control subjects will be involved for comparison among groups.
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.
