Filter by:Hyponatremia (HN) is the most common electrolytic disorder in the traumatic brain injury (TBI) population, found in 17 to 51% of patients according to the series. Two etiologies predominate in the literature, the Syndrome of Inappropriate Anti Diuretic Hormone (SIADH) and the Cerebral Salt Waste Syndrome (CSW), but none has been precisely described in terms of epidemiology, risk factors or severity. Moreover, SIADH and CSH were often confused in previous works. The main goal of our study is to assess retrospectively prevalence, severity, time to onset, length, risk factors of HN in a large population of TBI patients, as well as treatment modalities and prognosis. A specific distinction was performed between SIADH or CSW.
Establishment of effective, efficient, and evidence-based interventions in rehabilitation of working memory (WM) deficits after acquired brain injury (ABI) is sorely needed. Despite robust evidence for the usefulness of clinical hypnosis in a wide range of clinical conditions, and improved understanding of mechanisms underlying it ́s effects, the potential of clinical hypnosis in cognitive rehabilitation is virtually unexplored. The current study seeks to replicate resent intriguing findings where large effects of hypnotic suggestion were seen on WM capacity following ABI, and further, explore underlying mechanisms of change.
In patients with severe brain injury, maintenance and control of blood pressure is at the very first point in the management strategy, whether in anesthesia or in intensive care. In order to restore cerebral perfusion pressure (CPP) to appropriate levels (60-70 mmHg) while ensuring optimal perfusion of other vital organs, intravenous administration of vasodilator, inodilator or vasoconstrictor vasoactive agents is commonly used. These vasoactive agents, widely used to correct hypotension or hypertension, have their own effects on the load conditions of the left ventricle and the tone of the arterial tree, but also have effects on the microcirculation. The microcirculatory status of a tissue cannot be reliably predicted by considering only the macrocirculatory parameters usually measured. Therefore, in situations where organ perfusion is inadequate or compromised, patient management that includes the integration of the impact of vasoactive agents on the microcirculation seems essential for comprehensive hemodynamic treatment. The non-invasive study of microcirculatory perfusion and its interactions with the macrocirculatory network, using a minimally invasive method such as videomicroscopy, should allow a better use of the treatments used. For cerebral patients, routine management already includes very complete monitoring of all cardiopulmonary and cerebral systemic parameters. It is therefore imperative to study and propose new minimally invasive modalities for monitoring the microcirculation in order to define new therapeutic targets that take into account the microcirculatory compartment.
The purpose of this study was to observe the relationship between the changes of circulating extracellular vesicles and disease development and outcome in patients with traumatic brain injury, and to find early serum markers and potential intervention targets for disease monitoring in patients with traumatic brain injury. In addition, explore the source of extracellular vesicles as much as possible to prepare for subsequent basic experiments.
Sequences of muscle tendon vibrations allow to reproduce the sensory feedback during movement like locomotion and kinaesthesia. It is known that such a treatment promotes motor recovery after stroke assuming that it enhances neuroplasticity. The aim of the research is to study the activity in cerebrospinal circuitry to evaluate the neuroplastic changes during and after instrumented proprioceptive rehabilitation relying on sequences of muscle vibration in subacute stroke stages.
The purpose of this study is to assess a balance training program to see if it can be helpful to avoid falls in people who have had traumatic brain injuries (TBIs). The study will include 3 groups: TBI Intervention group , TBI Control Group, and healthy control group. TBI Intervention group - These individuals will participate in 16 anticipatory postural adjustments (APA) and compensatory postural adjustments (CPA) training sessions using the Neurocom Balance Platform. Each session will last for 1 hour. During the APA portion, participants will be provided with a visual cue on the front screen in the form of a countdown timer showing the remaining seconds to the onset of the upcoming perturbation. This information will allow an opportunity for the participant to adjust their posture to handle the upcoming perturbation in the best possible way and also train them to anticipate upcoming disturbances and execute corrective motor outputs. In CPA, after a 5 second pause, the platform will oscillate at 1 Hz, with a constant amplitude, in the anterior-posterior direction for 50 seconds, followed by an additional 5 second quiet period. The participant will wear a safety harness at all times and a spotter will be present at all times. TBI Control Group- They do not receive any intervention. healthy control group- They do not receive any intervention. All three groups will participate in two data collection sessions: Baseline and follow-up. At baseline and follow-up, we will collect functional, clinical, biomechanical, and physiological metrics. During training and data collection, a spotter will be present at all times to prevent falls and participants will be allowed as much rest as needed by them..
Our successful R01 discovered 1) the neural mechanistic difference between typically occurring convergence insufficiency (TYP-CI) and binocularly normal controls and 2) the underlying mechanism of office-based vergence and accommodative therapy (OBVAT) that is effective in remediating symptoms. Adolescent and young adult concussion is considered a substantial health problem in the United States where our team has shown that about half of patients with persistent post-concussion symptoms have convergence insufficiency (PPCS-CI), causing significant negative impact associated with reading or digital screen-related activities, and is believed to be one factor causing delayed recovery impacting return to school, sports, or work. The results of this randomized clinical trial will impact the lives of adolescents and young adults with PPCS-CI to guide professionals on how to manage and treat those with PPCS-CI by 1) comparing the differences between PPCS-CI and TYP-CI, 2) discovering the neural mechanism of OBVAT for PPCS-CI compared to standard-community concussion care, and 3) determining the effectiveness of 12 one-hour sessions compared to 16 one-hour sessions of OBVAT.
Traumatic brain injury (TBI) is a significant problem for U.S. Hispanic children. Compared to non-Hispanic children, Hispanic children have higher long-term disability and lower health related quality of life, even though differences are not present at hospital discharge. Rehabilitation decreases disability, but needs timely initiation, and long treatments in hospitals, community healthcare facilities and schools. Parents play a key role in their child's recovery. Hispanic parents face additional barriers to initiate and maintain outpatient treatments. They report knowledge gaps in TBI-education, community, and school support systems; language and health literacy barriers. The investigators developed, a bilingual bicultural theory-based program for Hispanic families consisting of Brain Injury Education and outpatient care Navigation (1st BIEN). It integrates in-person education enriched by video content delivered through mobile phones, with navigation during transitions to outpatient care and school return. The pilot established feasibility and acceptability of the program. This randomized control trial will determine efficacy to maintain long-term adherence to rehabilitation and reduce disability. It will enroll 150 parent-child dyads: children (6-17 y), with mild-complicated, moderate-severe TBI in 5 centers in Washington, Texas, Dallas, Utah and Oregon and their parents. Intervention group parents receive: One in-person education session, plus bi-weekly videos tailored to the child's TBI and therapies; and, 3-months of bilingual outpatient care navigation. Attention control parents receive one in person-education session, monthly well-child texts and usual institutional follow up care. Primary outcome is treatment adherence at 6 months post-discharge measured by percentage of follow-up appointments attended during the prescribed time at hospitals, and community care facilities. Secondary outcomes are functional status of the child using PROMIS parental report measures; and parental health literacy, self-efficacy, and mental health at 3, 6, and 12 months after discharge. Child's academic performance will be assessed using school records. The study evaluates a flexible and scalable intervention using mobile phones to aid transitions of care, improve treatment adherence and TBI outcomes. It addresses the needs of an understudied population and can serve as a model for TBI family centered care for at risk groups.
Children requiring inpatient rehabilitation treatment following acquired brain injury (ABI) are at risk for poor engagement in rehabilitative therapies. A within subject crossover design will be used to determine whether involving dogs in physical and occupational therapies while receiving inpatient rehabilitation improves patient engagement, how involving dogs improves engagement, and identify who is most likely to benefit. This project addresses the critical need to establish an evidence base for animal-assisted therapies in pediatric rehabilitation, incorporates innovative methods, and has the potential to lead to improved clinical care for children and adolescents receiving intensive rehabilitation following ABI.
The CONNECT-TBI Trial aims to develop safe, effective treatments for complex mTBI that improve cognitive functioning. Based on the compelling preliminary data generated by our study team, the objective of this study is to conduct a randomized, double-blinded, sham-controlled Phase II clinical trial of APT-3 combined with rTMS, HD-tDCS, or sham to treat cognitive control deficits in Veterans with complex mTBI and PPCS. At the Baseline Visit, participants will undergo demographic, neuropsychological, behavioral, and quality of life testing. They will also undergo structural MRI to permit modeling of their brain, resting/task-related fMRI to identify the CCN, and pseudocontinuous arterial spin labeling (pCASL) and diffusion tensor imaging (DTI) to assess for other pathologies. They will then be randomized to 16 sessions of APT-3 with concurrent rTMS, HD-tDCS, or sham stimulation delivered to the unique functional left dorsolateral prefrontal cortex (DLPFC), a primary node of the CCN. Lastly, they will repeat all baseline tests, and report on 3- and 6-month recovery levels to establish longevity and stability of subjective benefit. Given that this individualization protocol has never been attempted for cognitive rehabilitation in military mTBI, we expect this trial will generate useful effect sizes for HD-tDCS and rTMS to be used for powering the next step, a Phase III multi-center trial.
