NCT ID: NCT04044248 Recruiting - Cirrhosis, Liver Clinical Trials

TIPS Plus Transvenous Obliteration for Gastric Varices

Start date: April 4, 2019
Phase:
Study type: Observational

Variceal hemorrhage (VH) from gastric varices (GVs) results in significant morbidity and mortality among patients with liver cirrhosis. In cases of acute bleeding, refractory bleeding, or high risk GVs, the transjugular intrahepatic portosystemic shunt (TIPS) creation and transvenous variceal obliteration procedures have used to treat GVs. While these techniques are effective, each is associated with limitations, including non-trivial rebleeding and hepatic encephalopathy rates for TIPS and aggravation of esophageal varices, development of new or worsening ascites, and formation of difficult to treat ectopic varices for transvenous obliteration. Increasingly, however, TIPS and transvenous obliteration are viewed as complimentary procedures that can be combined to reduce bleeding risk and ameliorate sequelae of portal hypertension. Yet, despite a strong mechanistic basis for their combination, there are few studies investigating the combined effectiveness of TIPS plus transvenous obliteration. Thus, the aim of this single center prospective pilot study is to assess the effectiveness and safety of combined TIPS creation plus transvenous obliteration for the treatment of GVs, with the overall goal of improving the clinical outcomes of patients with VH related to GVs. The work proposed could lead to important advances in the treatment of bleeding complications due to liver cirrhosis.

NCT ID: NCT03968861 Completed - Encephalopathy Clinical Trials

Outcome After 24 Months of Participants in the TOBY Xenon Study

Start date: August 2014
Phase:
Study type: Observational

The objective of this study is to document the outcome at 2-3 years of age of participants of the TOBY Xe trial, to provide preliminary information about the later clinical effects of treatment with Xenon gas combined with moderate hypothermia following perinatal asphyxia. The TOBY Xe trial was a randomised controlled trial of inhaled xenon gas combined with hypothermia for the treatment of perinatal asphyxia. The trial primary outcome was changes on magnetic resonance parameters examined prior to discharge from hospital. Continuing clinical follow-up of trial participants is important following any therapeutic trial and is essential in early phase trials where information on the clinical effects of the intervention are lacking. Therefore, we have set up this study to determine the major clinical and neurological outcomes of participants of the TOBY Xe trial and to determine whether the magnetic resonance parameters in that trial are qualified to predict outcome following neural rescue therapy. This information is necessary for planning further studies of this intervention.

NCT ID: NCT03525431 Completed - Epilepsy Clinical Trials

Clinical Utility of Pediatric Whole Exome Sequencing

Start date: August 1, 2017
Phase: N/A
Study type: Interventional

The investigator aims to examine the clinical utility of WES, including assessment of a variety of clinical outcomes in undiagnosed pediatric cases.

NCT ID: NCT03173196 Completed - Encephalopathy Clinical Trials

Prospective Analysis of Septic Associated Encephalopathy Using the Non-invasive Acoustocerebrography-ACG

SAEACG
Start date: June 1, 2016
Phase: N/A
Study type: Observational

The patients of the group "sepsis" are measured several times with the non-invasive multi-spectral sonography (Sonovum "ACG-Diagnosesystem") (days 1, 3, 7 and 14). The patients of the group "control" are measured on days 1 and 3 with the system. A measurement takes 3 minutes. For this purpose two ultrasound heads are placed above the patient's ears and fixed with an all-head harness. The device is certified for CE application. There are no known health risks of ultrasound in humans.

NCT ID: NCT03138876 Completed - Encephalopathy Clinical Trials

EEG Cap for Identification of Non-Convulsive Status Epilepticus

Start date: May 30, 2017
Phase: N/A
Study type: Interventional

Altered mental status (AMS) is one of the most common reasons for inpatient neurology consultation. Non-convulsive status epilepticus (NCSE) is frequently on the differential diagnosis of the patient with AMS. NCSE becomes more refractory to treatment after one hour of seizure activity, making rapid identification and treatment of NCSE of great clinical importance. Currently, an electroencephalogram (EEG) technologist must be called in from home during non-workday hours in order to obtain a stat EEG. The investigators propose the time required for diagnosis of NCSE at Mayo Clinic can be significantly decreased with rapid placement of an EEG cap by the onsite neurology residents.

NCT ID: NCT02951559 Recruiting - Alzheimer Dementia Clinical Trials

SOLFAMU Study of Nasal Brushing Collected OLFActory MUcosa Samples in the Diagnosis of Human Encephalopathies

Start date: March 2016
Phase: Phase 4
Study type: Interventional

Encephalopathies are a group of central nervous system (CNS) affection with heterogeneous etiology. Several causes have been recognized including neurodegenerative, vascular, infectious, autoimmune, toxic or allergic affections or secondary to systemic disorders. While 30-50% of acute encephalitis remains without etiological definition, definitive criteria for neurodegenerative diseases are usually unavailable in vivo and possible or probable definitions are used. The Olfactory mucosa (OM) is the part of the nasal mucosa that carries the specialized sensory organ for the modality of smell; the olfactory epithelium is composed of five principal cell types including olfactory receptor neurons. A sample of OM may be collected through a rhinoscopy-guided brushing: it is well-accepted by patients, not-contraindicated in patients with raised intracranial pressure and associated with almost no side-effects. Nasal brushing has recently been proposed for the in vivo diagnosis of Creutzfeldt-Jakob disease (CJD). Aims of the project are: 1. Training of ear throat and nose (ETN), Infectious disease (ID) and neurology (NEU) specialists in the technique of nasal brushing; 2. Conducting a prospective study comparing the use of nasal brushing with gold-standard criteria in the diagnosis of Encephalopathies; 3. Increasing the diagnostic and prognostic power in the diagnosis of encephalopathies. A prospective, case control, multicentric study enrolling 400 patients and 100 controls (patients with nasal stenosis undergoing rhinoscopy for clinical reasons). Patients will be diagnosed and followed according to international guidelines and local clinical practice. Cerebrospinal fluid and magnetic resonance imaging will be used, where indicated, for the diagnosis according to the clinical or radiological suspect.

NCT ID: NCT02831010 Completed - Encephalopathy Clinical Trials

A Multi-Center Cohort Study of Risk Factors and Outcomes of Encephalopathy of Prematurity in China

NCT ID: NCT02451618 Terminated - Seizures Clinical Trials

Novel Epidermal Recording and Detection of Seizures

NERDS
Start date: January 27, 2015
Phase:
Study type: Observational

For any newborn that exhibits possible seizure activity or has altered mental status of unknown etiology, continuous bedside EEG recording is the standard of care to detect subclinical seizure activity. The experimental aspect of this study will be the application of test electrodes (EES or EKG) to evaluate if the electrodes can be used to produce a continuous bedside recording of brain activity in the same manner as an EEG recording, while ideally producing less irritation of newborn skin than conventional EEG electrodes.
