NCT ID: NCT04308577 Completed - Stroke Clinical Trials

Diet Induced Ketosis for Brain Injury - A Feasibility Study

Start date: October 5, 2020
Phase: N/A
Study type: Interventional

Each year, approx. 100 patients with severe brain injury is admitted to the Clinic for Neurorehabilitation/TBI Unit, Rigshospitalet. Severe brain injury results in local oxygen deficiency and acid formation in the brain, which together destroys brain cells. The purpose of this study is to investigate whether it is possible to carry out a ketogenic diet therapy for patients with severe brain injury for six weeks. Ketosis has been shown to be neuroprotective during and after severe brain injury.

Dexamethasone for the Treatment of Vasogenic Pericontusional Edema.

DEXCON-TBI
Start date: July 24, 2020
Phase: Phase 3
Study type: Interventional

The DEXCON-TBI trial is a multicenter, pragmatic, randomized, triple-blind, placebo controlled trial to quantify the effects of the administration of dexamethasone on the prognosis of TBI patients with brain contusions and pericontusional edema. Adult patients who fulfil the elegibility criteria will be randomized to receive dexamethasone or placebo. Patients who have suffered a head injury and have one or more cerebral contusions with visible pericontusional edema in the CT scan can be included in the study. The doses of dexamethasone will be a short and descending course: 4mg/6 hours (2 days); 4 mg/8 hours (2 days); 2 mg/6 hours (2 days); 2 mg/8 hours (2 days); 1 mg/8 hours (2 days); 1 mg/12 hours (2 days). The primary outcome is the Glasgow Scale Outcome Extended (GOSE) performed one month and 6 months after trauma. Other secondary outcomes are: compare the number of episodes of neurological deterioration; compare the symptoms associated with TBI; compare the presence of adverse events during treatment; compare the volume of pericontusional edema before and after 12 days of treatment in both groups of patients; and compare the results of the neuropsychological tests between the two groups of patients one month and 6 months after the TBI. The main analysis will be on an ''intention-to-treat´´ basis. A descriptive analysis of the baseline variables will be made for each treatment group. Logistic regression will be used to estimate the effect of dexamethasone and placebo on GOSE at one month and at 6 months, dichotomized in unfavorable outcome (GOSE 1-6) and favorable outcome (GOSE 7-8). Since the severity of the initial injury will determine significantly the final outcome of the patient, to assess the effect of dexamethasone, efficacy will also be analyzed using the 'sliding dichotomy'. A subgroup analysis will be carried out by stratifying the patients as they present more or less than 10mL of pericontusional edema in the preinclusion CT. We will perform an interim analysis with the patients included during the first year to calculate the conditional power. An independent statistician will blindly perform this analysis. At the same time a safety analysis will be also perfomed. A study with 600 patients would have about 80% power (two sided alpha=5%) to detect a 12% absolute increased (from 50% to 62%) in good outcome.

Study Examines the Feasibility, Safety and Benefits of Using a Specific Suspension Walking Device for Patients With Neurological Damage

Walk-Up
Start date: March 30, 2020
Phase:
Study type: Observational

This monocentric descriptive study addresses feasibility, safety and benefits of using a specific suspension walking device for patients with severe neurological injuries in the neuroICU of Montpellier University Hospital, France. Analyzes are retrospective on data collected prospectively during standard practice. All adult neurological patients hospitalized for > 48 hours and requiring mechanical ventilation from January 2018 to January 2019 are included, and divided into two groups: beneficiaries of suspension walking during the ICU stay, and non-beneficiaries. Characteristics of the two groups are compared and reasons for not using suspension walking recorded (feasibility). After pooling all suspension walking sessions, changes in clinical parameters during sessions and occurrence of adverse events are described (tolerance).

Participation and Executive Functions in Adults Following Traumatic Brain Injury In Sub-Acute Inpatient Rehabilitation

Start date: March 1, 2020
Phase: N/A
Study type: Interventional

Aim: To examine the feasibility of a new treatment protocol in improving executive function deficits and participation in daily activities of adults with TBI at discharge and one month post-discharge. A double-blind (assessors) randomized control trial (RCT) with two groups, experimental and control. This study will include 40 adults hospitalized in the inpatient Head Trauma unit. Potential patients will be approached by occupational therapists working in the inpatient Head Trauma rehabilitation unit and be invited to participate in the study. If they agree, they will be asked to sign an informed consent form. Then they will undergo a screening assessment. Participants who are found eligible will be then administered a cognitive assessment battery. Then they will be randomly allocated to either the experimental (new treatment protocol) or the control (conventional therapy) group. In both groups, the intervention will include 18 treatment sessions of 45 minutes, between three to five times a week depending on the participant's state, over a period of four to six weeks. Following the intervention, participants will undergo the assessment again. Participation questionnaires will be administered by telephone one month post-discharge.

The Utility of Positive Psychology in Military TBI Rehabilitation

Start date: September 2019
Phase: N/A
Study type: Interventional

Service members and veterans (SMVs) report more persisting symptoms following traumatic brain injury (TBI) compared to civilian populations (Ommaya, Ommaya, Dannenber, & Salazar, 1996). Therefore, it is important to utilize interventions that reduce psychological impairments and increase resiliency during military TBI rehabilitation. Unlike traditional behavioral health treatments that focus on reducing maladaptive behaviors and negative thoughts, positive psychological treatments focus on increasing positive emotions to increase well-being. There is substantial growing evidence demonstrating that cultivating positive emotions is preventative and improves resiliency and psychological (Bolier et al., 2013; Sin & Lyumbomirsky, 2009), cognitive (Estrada, Isen, & Young, 1997; Ashby & Isen, 1999; Isen & Daubman, 1984; Isen, Daubman, & Nowicki, 1987; Fredrickson & Branigan, 2001), and health outcomes (Pressman & Cohen, 2005). This study will examine the effectiveness of traditional behavioral health treatment versus behavioral health treatment with an added positive psychological group treatment in terms of psychological, cognitive, and health outcomes during TBI rehabilitation. The hypothesis is that SMV's with TBI will experience improved outcomes with added positive psychological treatment compared to traditional behavioral health treatment alone. There will be about 100 people taking part in the study, randomly assigned to either a traditional behavioral health treatment group or an alternative behavioral health treatment group (therefore, up to 50 people will be enrolled in each) at the Fort Belvoir Intrepid Spirit Center over a period of 30 months. Study participants will be randomly assigned to groups, and over 3 months the study procedures include participating in group behavioral health treatment and/or individual behavioral health treatment and completing pre/post-treatment questionnaires focusing on psychological, cognitive, and health outcomes. The behavioral health intervention has not been well-studied; thus, the behavioral health intervention is considered experimental for the treatment of psychological symptoms. Additionally, the impact on other areas of functioning (i.e., cognitive functioning and overall health) is currently unknown.

NCT ID: NCT04244058 Suspended - Clinical trials for Traumatic Brain Injury

Changes in Glutamatergic Neurotransmission of Severe TBI Patients

Start date: September 23, 2020
Phase: Early Phase 1
Study type: Interventional

Studies in patients with disorders of consciousness (DOC) after severe brain injury implicate dysfunction of the anterior forebrain mesocircuit dysfunction a key underlying mechanism. The anterior forebrain metabolism in DOC is markedly downregulated across brain regions underpinning highly elaborated cognitive behaviors demonstrating a collapse of the level of synaptic background activity required for consistent goal-directed behavior and arousal regulation. Since dopamine levels are one of the primary controllers of the level of synaptic background activity within these forebrain structures and in regulating excitatory glutamatergic homeostasis, the investigators propose to investigate the specific contribution of presynaptic dopamine function in glutamatergic neurotransmission in posttraumatic DOC. The aim of the present study is to measure metabotropic glutamate receptors 5 occupancy in the main gutamatergic structures of the brain using (3-[18F]fluoro-5-(2-pyridinylethynyl)benzonitrile)-positron emission tomography ( [18F]FPEB-PET) at rest and following a short pharmacological challenge with amantadine, an N-methyl-D-aspartate receptor (NMDA-R) antagonist, following L-DOPA, and amantadine + L-DOPA. Using this novel technique in DOC the investigators will characterize the relevance of a presynaptic deficiency to synthesize and/or release dopamine in the final regulation of excitatory interneurons of the anterior forebrain mesocircuit. It is unknown whether glutamatergic neurotransmission is affected across the population of subjects with DOC and, if this condition is secondary to a presynaptic dopaminergic failure of the anterior forebrain mesocircuit (i.e., down-regulation). Since the investigators previously identified the existence of a presynaptic dopaminergic deficit in these subjects due to a failure in the biosynthesis of dopamine, the investigators will evaluate if by providing the main biological substrate of the biosynthesis process (i.e., L-DOPA) the glutamatergic system regains homeostasis. The investigators therefore propose to investigate patients with posttraumatic DOC using [18F]FPEB-PET at rest and following short pharmacological challenges aimed at increasing glutamate and dopamine release.
