Active clinical trials for "Brain Injuries, Traumatic"

The aim of this study is to investigate whether a tDCS-accompanied intensive naming therapy leads to a performance improvement in patients with chronic aphasia induced by a moderate TBI

Head injuries are responsible for 1.4 million visits to hospital each year in the United Kingdom (UK). Most patients are allowed home the same day and make a full recovery, but some will have persistent symptoms. The investigators aim to use the latest generation of imaging technology to investigate those with mild traumatic brain injury (mTBI) to better assess them. The investigators will invite patients presenting following trauma to the Emergency Department at Queen's Medical Centre, Nottingham, UK to participate. The investigators will compare those who have a suffered an mTBI to those who have non-head traumatic injuries. The investigators will use two magnetoencephalogram (MEG) systems and ultra-high field magnetic resonance imaging (MRI) to record the functioning and structure of the brain within days of participants' injury. The investigators will test memory and thinking skills, then follow participants for six months, record the severity of participants' symptoms, and find out who does not make a full recovery. Multimodal imaging will consist of a standard MEG device using Superconducting Quantum Interference Device (SQUID) sensors, a novel MEG device using Optically Pumped Magnetometer (OPM) sensors and seven Tesla MRI. The investigators will test whether these innovative imaging techniques are more sensitive to the acute damage that mTBI causes than routine imaging. The investigators will also test whether early imaging can reveal who is most seriously affected, identifying those who will not recover without additional support. It is currently not clear what the predominant mechanism of damage that causes these long-term problems is and the investigators hope this study will address this. The Medical Research Council is funding this work

Traumatic brain injuries (TBI) are one of the most common reasons for patients to attend the emergency department (ED). 90% of patients with TBI are defined as mild TBI (mTBI). A small minority of patients with mTBI would show pathological computed tomography (CT) results and even fewer need neurosurgical intervention. Nevertheless, complications would be so severe, if neurosurgical intervention is delayed, that it has become common practice to subject all patients with mTBI to CT. The high number of CT scans has an impact on health care resources but may also involve risk by subjecting patients through potentially harmful ionizing radiation. Several independent research groups have attempted to optimize CT use in mTBI patients by forming guidelines that aim to identify patients at high risk for intracranial complications. Most guidelines have been published in the past 15 years and have been validated both prospectively internally and externally; all guidelines have been shown to be safe when implemented in clinical use with few missed complications. However the number of CT scans has not been reduced dramatically, in some cases it has even increased. In 2013, the new Scandinavian guidelines (SNC13) were published. They are the first guidelines that use a biomarker, S100B, as a tool for managing patients with mTBI. Although S100B has a low specificity for intracranial complications, a high sensitivity makes it suitable to be implemented into clinical practice as a tool for CT reduction. Previous SNC guidelines have been compared to other prominent guidelines with impressive results. The SNC13 have been externally validated in a retrospective study from the USA that was underpowered for important outcomes. Nevertheless, SNC13 have already been partially implemented in clinical practice in Scandinavia. However, a strict multicenter validation has not been performed yet nor a systematic comparison to other available guidelines. Our primary aim is to validate the performance of the SNC13 in predicting intracranial complications in adult patients presenting with traumatic head injury in Swedish hospitals. A secondary aim is to compare the performance of SNC 13 with 6 other clinical guidelines, with respect to important outcomes. Moreover, to explore the performances of different biomarkers in predicting intracranial complications in predefined subgroups of TBI. Finally, to evaluate the possibility of further improvement of the SNC13.

The research project aims to better understand the multiple factors related to the clinical evolution and the social participation of traumatic brain injured (TBI). The project will provide better understanding of the patients' evolution during rehabilitation after TBI in terms of adaptation and social participation, assess the effect of rehabilitation and study social participation outcomes and quality of life of TBI patients one-year post-rehabilitation. Project benefits include improvement of clinical practices and support in decision-making. The objectives of this research project are: Part 1: To provide a picture of the evolution, in terms of social adaptation and participation of patients during rehabilitation after a TBI. Part 2: To study social participation outcomes and quality of life of TBI individuals one year after the end of their rehabilitation.

The purpose of this study is to observe the relationship between the level of lipid peroxidation products in serum of patients with traumatic brain injury and secondary coagulation disorders.

Mild traumatic brain injury (mTBI) accounts for 70-90% of brain injuries, with 600 cases of mTBI per 100 000 people in the united states, but only 100-300 mTBI patients per 100 000 people receive hospital-based care. Symptoms reported immediately after injury tend to diminish over the following 10 days and are generally resolved by 3 months. However, in 15-25% of cases , problems persist, and may even worsen, at 3 months. Physical, emotional, and behavioral factors can be affected. Physical disorders include pain and fatigue. Sleep disorders are also common. Persistent symptoms can affect patient outcomes (affecting all aspects of life) and increase public healthcare costs .In a previous study (NCT03811626, Efficacy of Psychoeducation and Cognitive Rehabilitation After Mild Traumatic Brain Injury for Preventing Post-concussional Syndrome in Individuals With High Risk of Poor Prognosis: A Randomized Clinical Trial. The investigators were able to demonstrate that early multidisciplinary management improved the outcome and prognosis of patients by statistically significantly reducing the percentage of patients with Post traumatic syndrome distress at six months (6% for the treated group versus 52% for the control group, p < 0.001). It seems important to verify that if this short-term improvement (6 months after the trauma) persists in the long term, and therefore at a distance from the end of the initially proposed rehabilitation.

Severe traumatic brain injury (TBI) is the leading cause of death and disability among people under 45 years of age and a major public health problem. Although management of severe TBI patients has gradually improved with the establishment of intensive care units (ICU) and the development of practice guidelines, mortality is still high - ranging from 30 to 50% - with 30% of survivors suffering from severe neurological sequelae such as neurovegetative states. Families and medical teams are frequently called upon to determine reasonable and appropriate goals of care for brain injured patients. They may have to consider high intensity of care, but also the withdrawal of life-sustaining therapies in accordance with patient wishes. Physicians involved in the care of severe traumatic brain injury have expressed serious concerns about hasty decisions made in the absence of appropriate evidence of unfavourable prognosis. The purpose of the TBI-Prognosis study is to develop a prognostic model by using a multimodal approach of different prognostic indicators and their evolution over time in the acute phase of care. The results of this study will provide better objective information that will facilitate the shared-decision making-process with families and relatives.

Brain trauma is an important burden in traumatologic intensive care. In these patients the treatment is guided by a cluster of multimodal monitoring parameters. Despite this it is difficult to assess the actual physiopathologic status of the brain. Changing the position of these patients (semi-seated to lying position) causes changes in the hémodynamics brain conditions, so in monitoring parameters . The analysis of these changes can givr us valuable clinically informations.

Comparison between a normothermia protocol and current protocol (acetaminophen plus blankets) Normothermia Protocol is successful in achieving and maintaining normal temperature in moderate to severe Traumatic Brain Injury (TBI) patients.(using Arctic Sun for 96 hrs from admission to Neuro ICU) Normothermia is translated into improved neurologic Outcome and survival compared to standard of care (Physician management)

The purpose of this study is to evaluate physiological variables to the decision about the appropriate time to discontinuation of mechanical ventilation in patients with traumatic brain injury. It is expected that these variables are effective in predicting the outcome of weaning from mechanical ventilation.
