Filter by:The objective of this study is to compare the effectiveness of a personalized patient education program to the current hospital education and evaluate its impact using patient satisfaction scores. The investigators hypothesize that a personalized patient education intervention will increase patient's understanding of their diagnosis and satisfaction with the care as reflected in the survey results.
This research study will evaluate the effectiveness and estimate the feasibility of administering an investigational drug called 'CN-105' (the study drug), to prevent postoperative cognitive decline, delirium (serious confusion) and underlying brain inflammatory and brain activity changes in adults 60 years and older undergoing surgery.
The primary objective of the study is to evaluate the safety and immunogenicity of non-adjuvanted and adjuvanted monovalent VEE VLP Vaccine in healthy adults (ages 18-50 years) when administered via intramuscular (IM) injection at escalating doses of 2 μg, 10 μg, and 20 μg as a 2-dose primary series (Day 0, Day 28) with a Day 140 booster dose. The secondary objective of the study is to evaluate immunogenicity of the vaccine at the aforementioned time points
The purpose of this study is to proof and investigate the effectiveness and safety of the invented device named "Human Lumbar Puncture Assist Device (LPat)" as an assist tool to be utilized to improve the success rate of performing lumbar puncture (LP), avoid side effects from multiple punctures, avoid excess radiation if the LP need to be done under fluoroscopy, and need to obtain none traumatic tap for better CSF analysis.
DESIGN: exploratory, prospective, natural history, imaging cohort study BACKGROUND: Stroke causes a strong inflammatory response in the brain which is thought to contribute to permanent brain damage in stroke patients. To develop new therapies targeting inflammation we need to better understand how inflammation affects the injured brain tissue and how it relates to neurological deficits that directly affect the patients' quality of life. AIMS: To track the extent and location of inflammation in the brain after stroke over a period of 90 days. The study will explore whether the most inflamed areas in the brain undergo the most damage after stroke and correspond to the cognitive and neurological deficits experienced by stroke patients. METHODS: The study involves an initial screening visit and 2 study imaging visits at days 15 and 90 after the stroke episode. Patients will undergo: 1. Two 90-minute brain imaging sessions using Positron Emission Tomography (PET) (involves injection of safe radiotracers which attach to brain immune cell markers TSPOs and light up the inflamed areas in the brain), 2. Two 45-90 minute Magnetic Resonance Imaging (MRI) scanning sessions (include administration of safe chemical contrast agent Gadolinium), 3. Physical and neurological examinations (vital signs, assessments of mobility and cognitive functioning), 4. Blood testing (routine measurements, blood inflammation markers, and genetic testing for TSPO marker). Venous cannula will be inserted into the forearm for the duration of the scans. POPULATION: 15- 25 patients (recruitment will cease once 15 patients have completed the study) ELIGIBILITY: Male and female stroke patients, aged 18-85, with a recent (within last 10 days) ischemic stroke of moderate severity, able and willing to provide informed consent LOCATION: Patients will be recruited at the Charing Cross Hospital, Imperial College Healthcare NHS Trust, and study scans will be performed by Invicro Centre for Imaging Sciences, Hammersmith Hospital DURATION: 18 months FUNDED BY: Biogen Idec Ltd
The study is to explore the treatment effects and long-term prognosis (12 months and 24 months after immunotherapy) by comparing the early plasma exchange (PE) combined with medication therapy with the PE after medication immunotherapy in autoimmune encephalitis (AE) patients, to make clear that the early PE can be more effective than the treatment of PE after medication immunotherapy. As well as, the study is to explore whether PE is also effective in AE with autoantibody synthesis in the sheath, positive cerebrospinal fluid antibody and seronegative.
Most of patients with autoimmune encephalitis are left with permanent cognitive deficits of varying severity. The patients' life and career would be affected definitely by cognitive deficits. Recently, more and more clinical physician have begun to focus on cognitive impairment of patients with autoimmune encephalitis. Generally, the outcome was measured by the modified Rankin Scale (mRS). However, the mRS are commonly used to evaluate the degree of disability or dependence in the daily activities of the patients suffering from a stroke and cognition function were minimally evaluated in this scale. It is crucial to adopt detailed cognition tools to study the long-term cognitive outcomes and as an indicator of overall curative effect judgment in autoimmune encephalitis. Currently, only early immunotherapy is uniformly and consistently considered to produce favorable cognitive outcomes. However, studies concerning the association of second-line immunotherapy with cognitive outcomes have been scarce and have shown conflicting results regarding autoimmune encephalitis. Hence, the goal of this study was to explore cognitive neural mechanism of autoimmune encephalitis by using neuropsychological tests and multi-mode MRIs.
For this project, neflamapimod and placebo will be provided free of charge by the EIP company (www.eippharma.com). Neflamapimod is currently tested in 2 clinical trials in AD, one in Europe (The Netherlands) and one in the USA (clinical trials.gov/VX-745). The company commenced in May 2015 dosing in two phase 2a clinical studies in patients with Early AD: one in the Netherlands that is focused on PET amyloid imaging as the primary biomarker of drug effect, and one in the US (California) that is focused on Cerebrospinal fluid (CSF) evaluation to determine CSF drug concentrations and effects on inflammatory markers and disease biomarkers. Pharmacokinetic evaluation in these patients has demonstrated blood drug concentration levels in the predicted therapeutic range; and importantly, the data from the US study demonstrate that the drug achieves target drug concentrations in CSF, thus confirming the drug robustly enters the brain in humans. The present project offers us a unique chance to test this promising drug in AD patients. The aim of the study is to focus on PET neuroinflammation imaging as the primary biomarker of this drug effect. The chosen biomarker for imaging neuroinflammation in patients is [1 8F]-DPA714.
The Danish Study Group of Infections of the Brain is a collaboration between all departments of infectious diseases in Denmark. The investigators aim to monitor epidemiological trends in central nervous system (CNS) infections by a prospective registration of clinical characteristics and outcome of all adult (>17 years of age) patients with community-acquired CNS infections diagnosed and/or treated at departments of infectious diseases in Denmark since 1st of January 2015.
A study of the study vaccine (JECEVAX- VABIOTECH-Vietnam) and a licensed vaccine (JEVAX-VABIOTECH-Vietnam) is conducted in Vietnamese children, aged 9 to 24 months to assess the safety of the study vaccine compares to licenced vaccine. Two hundred and twenty children are enrolled and randomly assigned into 2 groups (110 children/group), each of which receive 2 doses of study / control vaccine subcutaneously, at 28-34 days interval. Safety data included immediate reaction at the injection site and systemic reaction within 30 min of administration, solicited and unsolicited adverse events occurs from the 1st dose to 28-34 days after first dose and from the second dose to 28-34 days after 2nd dose. SAE (from start of first dose to 28-34 days after second dose).
