Filter by:Vasoactive intestinal peptide (VIP) is a peptide of 28 amino acid residues that belongs to the glucagon/secretin superfamily of peptides. Along with other neuropeptides, such as calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP), it is released from the trigeminal afferents and exerts a strong vasodilating activity on the cranial vasculature. Especially, it shares 70% structure with PACAP and acts on the same receptors. But, unlike it, VIP cannot induce a long-lasting vasodilation and has a modest capability to induce migraine attacks. Whether it may induce migraine-like attacks in migraine patients, as a twenty-minute infusion of PACAP, is unknown.
Prospective, multi-site, single-arm study to evaluate the diagnostic yield of cWGS in adults with neurological disorders. A single cohort naive of genetic testing will receive standard of care testing for 180 days followed by cWGS. The cohort will be followed for a total of 365 days following enrollment.
Uremic encephalopathy is an organic brain disorder may be frequently seen in patients with acute or chronic renal failure. Certain neurological symptoms can be found under clinical glomerular filtration rate of 15 ml/minutes. The above mentioned neurological disorders can be due to uremic toxins as well as many other reasons such as metabolic and hemodynamic disturbances, inflammation, or oxidative stress. Most frequent symptoms are impaired consciousness, lethargy, cranial nerve involvement, nystagmus, dysarthria, and even coma and death. Brain tissue may receive damage and some secondary biomarkers may appear in case BUN (Blood Urea Nitrogen) level is >175 mg/dl together with neuroinflammation. Although hemodialysis is a temporary solution in terms of treatment, these symptoms may be reversible in the long-run with organ transplantation. A rigorous neurological assessment before transplantation is important for identifying the severity and distribution of the neurological disorder as well as defining the abnormalities that are responding to the current treatments and foreseeing potential postoperative prognosis. S100β is excreted by astrocytes in brain damage cases. S100β level rises when brain damage starts, thus it may be used in the prognosis of brain damage in its early period. Neuron-specific enolase (NSE) functions as intracytoplasmic enzyme and serum level rises in neuron damage. Glial fibrillary acidic protein (GFAP), on the other hand, is the intermediary filament cytoskeleton protein found in astrocytes. It has the same root structure with S100β. The purpose of this study is to assess neurological damage by looking at the levels of S100β, NSE and GFAP in patients who underwent kidney transplantation and to analyze the impacts on the prognosis.
Multiple sclerosis (MS) is a disease of autoimmune system which attacks the central nervous system and that is one of the most common inflammatory diseases and has caused a heavy disease burden on patients. In the world, the prevalence of MS is on the rise, and the annual growth rate of MS patients in Taiwan is much higher than the whole world (3.78 times). However, it has no discussion or study in references at present, and it is worthwhile to research. MS is not a fatal disease, but its complications make the mortality of its patients three times higher than that of general population. This study will explore the survival and the causes of death for MS patients in Taiwan by cohort study of fourteen years. In addition, in the recent years, the MS patients in Taiwan and the medical resource consumption has increased largely, and it is necessary to conduct the research.
The objective of this study is to test the safety and preliminary efficacy of staged bilateral subthalamotomy performed using the ExAblate Transcranial System for the treatment of Parkinson's disease (PD) motor features
Stroke is the 4th leading cause of mortality in Hong Kong. It also carries considerable socioeconomical consequences due to disability. Ischemic stroke can be classified by the TOAST classification, which includes large artery atherosclerosis, cardioembolism, small-artery occlusion and other causes (1). Among which, intracranial atherosclerosis (ICAS) had been major cause of acute ischemic stroke (AIS) in the Asia Pacific. It was estimated as high as 24.1% of AIS or transient ischemic attacks (TIAs) were attributed to ICAS in China (2). Management of ICAS related strokes has been challenging owing to its high rate of recurrence despite medical therapy. Recent randomized clinical trial suggested that aggressive medical therapy may result in reduction in recurrence compared with historical cohorts (3). Our group has previously observed a 2.5-fold increase in atrial fibrillation related stroke over a 15-year period (4). The inverstigator also observed a decline in ICAS related AIS as well as its recurrent stroke risk throughout the recent years. Possible mechanisms include better management of metabolic risk factors and aggressive secondary prevention. Other possible reasons are increased atrial fibrillation (AF), small vessel disease (SVD) or other stroke mechanisms. This study is aim to find the evolution of different stroke subtypes in relation to the characteristics of our stroke population over a 15-year period. This may influence territorial prevention strategy.
The objective of this study is to evaluate the safety and feasibility of Auto Focusing (AF) echo imaging using the ExAblate Neuro system
The purpose of this double-masked, randomized, controlled, multiple-dose study is to evaluate the efficacy, safety, tolerability and systemic exposure of sepofarsen (QR-110) administered via intravitreal injection in subjects with Leber's Congenital Amaurosis (LCA) due to the CEP290 p.Cys998X mutation after 24 months of treatment
Subjects completing participation in study PQ-110-001 (EudraCT 2017-000813-22 / NCT03140969) will be given the opportunity to enroll into the extension study for continued dosing if available data support current and/or future benefits for the subject. Study PQ-110-002 will provide long-term safety, tolerability, pharmacokinetic (PK), and efficacy data of QR-110.
The European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM) joint guidelines for post-resuscitation care recommend a multimodal approach to prognostication of neurological outcome. However, head computed tomography (CT) which is commonly used for predicting long-term neurological outcome after cardiac arrest has not yet been examined prospectively in a clinical trial. The primary purpose of the TTM-2 CT-substudy is to prospectively investigate and compare various methods of diagnosing generalized oedema on CT after cardiac arrest and it´s ability to predict long-term neurological outcome.
