CMK-0301 is a multi-site, randomized clinical trial to evaluate the safety and efficacy of [F-18]Flornaptitril-PET (F-18 FNT-PET) for the prediction of clinical progression of Mild Cognitive Impairment (MCI) with either Suspected Chronic Traumatic Encephalopathy (CTE) or Alzheimer's Disease (AD). The primary objectives of the study are to: (1) To determine the accuracy of F-18 FNT-PET in prediction of clinical decline and (2) To assess the safety and tolerability of F-18 FNT. The secondary objectives include: (1) To demonstrate the feasibility of F-18 FNT-PET in differentiation of participants with suspected chronic traumatic encephalopathy (CTE) from those with suspected Alzheimer's disease (AD) by trained image readers, (2) To evaluate disease progression in participants with suspected CTE or AD and (3) To evaluate the correlation between F-18 FNT-PET regional and summary visual reads scan and other assessments.
The study aims to evaluate the safety and efficacy of the Supernova stent retriever device, developed by Gravity Medical Technology, for treating acute ischemic stroke. The device is used to remove blood clots and restore blood flow to the brain .
Acute liver failure in cirrhotic patients is associated with a one-month mortality of 48%. Encephalopathy, largely related to hyperammonemia, is a frequent complication of liver failure and is a poor prognostic marker. Lactulose decreases ammonia by acidification of the colon, replacement of urease-producing bacteria and creation of a laxative effect. Thus, the administration of lactulose in patients with severe hepatic encephalopathy reduces mortality by more than 40%. In intensive care patients, lactulose is often administered rectally. The use of simple rectal tubes is associated with frequent leakage of lactulose as well as faecal discharge and therefore risks of infection and skin lesions. Balloon rectal tubes with a drug delivery valve have recently been developed and used in this indication. The aim of this study is therefore to describe the use of these balloon rectal tubes to administer Lactulose in severe hepatic encephalopathy. This suggests that ammonia reduction in these patients may prolong survival time. No studies have described the administration of Lactulose via the rectal route with a balloon tube. The descriptive methodology is therefore appropriate. This is a preliminary study allowing data collection to establish the methodology for a subsequent clinical trial.
Hepatic encephalopathy is (HE) defined by the neurological and/or neuropsychological symptoms caused by an acute or chronic liver disease and/or a portosystemic shunt. Its pathophysiology is still debated, although the synergic role of hyperammonemia and inflammation is now admitted for years. Several additional mechanisms have been suspected, one of them being an altered permeability of the brain blood barrier (BBB). Nevertheless, many aspects remain poorly understood. The rise of "-omics" techniques, and especially metabolomics, allowed to identify more precisely the different metabolic pathways that are involved in the pathophysiology of HE. Using a high flow chemistry technique and multivariate data analysis, metabolomics is an accurate way to understand the pathophysiology and pathogenesis of multifactorial diseases such as HE. Several studies have been published in cirrhosis. It has been suggested that serum metabolites at admission, as well as thyroxine, can predict advanced HE in patients without brain failure. In a cohort including more than 600 patients, a higher microbially-derived metabolites, together with a lower thyroxine level, were associated with further development of brain failure. In another study from the same team, serum and urinary metabolites were significantly different in hospitalised patients who had developed poor outcome or not. Another study conducted in the CANONIC cohort as also found changes in metabolites of patients with cirrhosis and acute-on-chronic liver failure (ACLF), revealing mitochondrial dysfunction in peripheral organs that may contribute to organ failures. Last, our team previously analysed plasma and cerebrospinal fluid (CSF) samples of patients with cirrhosis and HE hospitalised in intensive care unit (ICU), showing alteration in ammonia and amino-acids metabolism, and also in energy metabolism. However, in the latest study, ALCF grading was not available. As many of these patients were in a severe condition, one could hypothesize that the metabolomic changes observed in these patients may have been confounded by an ACLF profile. Therefore, the objective of this study is to characterize the metabolomic fingerprints of HE in patients with cirrhosis, using 4 different groups of patients: patients with or without HE, with or without ALCF.
The goal of this open-label, single-blind, controlled-trial is to evaluate brain changes evaluated with diffusion Magnetic Resonance Imaging (MRI) and functional MRI in patients with high-frequency episodic migraine and chronic migraine that will be treated with Fremanezumab, 12 weeks after the treatment onset, compared with the baseline. Type of study: Phase IV clinical trial Participant population: high-frequency episodic migraine and chronic migraine. Participants will be treated with Fremanezumab.
This study aims to investigate the influences behind patient choices regarding involvement, discontinuation, or re-engagement in hepatic encephalopathy clinical trials. Uncovering these factors is essential to enhance the relevance and efficacy of future research endeavors. In essence, this trial aims to deepen understanding of the factors influencing participation in hepatic encephalopathy clinical trials. Elevating participation rates could expedite the development of innovative treatments for this challenging condition.
The goal of this single-centre longitudinal observational study is to create reference values for diastolic function parameters in neonates born at 35 weeks' gestation or above, and to assess the influence of pre-defined antenatal, intrapartum, maternal, and neonatal factors on cardiac function. The main question it aims to answer are: - What are the normal reference ranges for parameters of diastolic cardiac function in neonates? - How are these influenced by maternal, intrapartum and neonatal factors? - Do the diastolic changes noted during the first two days of life persist into infancy? Participants will have four echocardiographic assessments in total: - Two during the first 48 hours of life (prior to discharge home) - Two during infancy (as an outpatient)
This is an observational study in patients who require clinical anesthesia. The main purpose of this study is to understand whether there are differences in the cerebral blood flow, and oxygen metabolism affected by different types of anesthesia. Subjects who require clinical anesthesia for a clinical MRI and for whom the use of anesthetics for the exam are in clinical equipoise are asked to join the study. All eligible subjects will be asked to provide informed consent before participating in the study.
The goal of this clinical trial is to investigate the feasibility if a remotely administered smartphone app can increase the volume and intensity of physical activity in daily life in patients with isolated Rapid Eye Movement (REM) sleep behaviour disorder over a long period of time (24 months). Participants will be tasked to achieve an incremental increase of daily steps (volume) and amount of minutes exercised at a certain heart rate (intensity) with respect to their own baseline level. Motivation with regards to physical activity will entirely be communicated through the study specific Slow Speed smartphone app. Primary outcomes will be compliance expressed as longitudinal change in digital measures of physical activity (step count) measured using a Fitbit smartwatch. Exploratory outcomes entail retention rate, completeness of remote digital biomarker assessments, digital prodromal motor and non-motor features of PD, blood biomarkers and brain imaging markers. Using these biomarkers, we aim to develop a composite score (prodromal load score) to estimate the total prodromal load. An international exercise study with fellow researchers in the United States and United Kingdom are currently in preparation (Slow-SPEED). Our intention is to analyse overlapping outcomes combined where possible through a meta-analysis plan, to obtain insight on (determinants of) heterogeneity in compliance and possible efficacy across subgroups
