Filter by:Approximately 150,000 children present each year to emergency departments (EDs) in the US with concussion and many more are treated by primary care physician, or outpatient specialists. Concussion is defined as a traumatically induced transient disturbance of brain function and involves a complex pathophysiological process. There is a variety of symptoms related to concussion, and the diagnosis of concussion requires the use of symptom-checklist. Since there is a various degree of the severity of those symptoms, the diagnosis is a subjective one and lacks sensitivity. One major problem is that approximately one-third of the children with concussion experience ongoing somatic, cognitive, and psychological or behavioral symptoms, referred to as persistent post-concussion symptoms. A recent study that investigated the validity a 12-point PPCS risk score revealed that it had modest validity (0.71). Moreover, one of the greatest concerns is the child's schedule return to activity. Since the basic mechanism for concussion is acceleration/ deceleration movement of axons, it is likely to be expressed in desynchronization of delta wave activity between anterior hemispheres as seen in pathological problems related to attention and/ or working memory). The aim of this proof-of-concept study is to find-out whether interhemispheric desynchronization of delta waves (IHDD) in the anterior hemispheres can identify acute concussion in children. If the investigators find that IHDD can accurately diagnose acute concussion, a second objective will be to examine whether this index can be a useful tool in the follow up of patients with persistent post-concussion symptoms.
Microbiome studies may be highlighted as crucial in the development of depression for TBI patients. The microbiota-gut-brain connection may further provide an opportunity for microbiota manipulation to treat the TBI patients with depression.This study is to investigate whether exist the relationship between depression and circadian rhythm of patients with TBI or not and focus the study on the potential of the host-microbiota interaction in regulating depression.
Traumatic brain injury (TBI) is a serious condition with high morbidity and mortality. The Glasgow score alone, assessed at the initial phase, is not enough to determine the prognosis. The aim of this study is to define and to evaluate a prognostic score for early death based on clinical and CT-scan findings in an observational retrospective derivation cohort of patients hospitalized for traumatic brain injury. This cohort will allow us to carry out a uni- and then multi-variate analysis so as to create a prognostic score for early death. We will subsequently test this score in a prospective validation cohort.
Head injury is a frequent motive of consultation in paediatric emergency units and the first cause of mortality in infants of more than one year old in developped countries. The indication of performing cerebral CT scans currently depends on clinical decision based on recommendations used in adults. In this way, 60 to 90% of scans are normal in children with head injury. CT scan is expensive and irradiating with the risk of increasing the cancer in children. Protein S100B and copeptin are biomarkers which have shown their ability to detect cerebral lesion in children with head injury. (protein S100B and /or in adults protein S100B and copetin). It is the first clinical biological evaluation of severity of head injury based on dosing of copeptin alone or associated with protein S100B. Furthermore, the evaluation of the biomarkers GFAP, NFL, Tau and UCHL-1 is today necessary from a scientific point of view and to optimize the diagnostic and prognostic value of these biomarkers which can be combined. Indeed, these protein biomarkers are biologically linked to the protein S100B and copeptin, and will allow a more specific and more thorough evaluation of the presence of brain damage at the cellular level. More specifically, the measurement of the S-100B and GFAP proteins will allow evaluation of gliovascular damage while those of copeptin, NFL, Tau and UCHL1 proteins will allow evaluation of neuronal damage. The assay of these different biomarkers will also be carried out on a control population, without head injury or neurological or inflammatory pathologies, in order to establish the standards of these biomarkers on a pediatric population of similar age.
Microbiome studies may be highlighted as crucial in the development of sleep disorder for TBI patients. The microbiota-gut-brain connection may further provide an opportunity for microbiota manipulation to treat the TBI patients with sleep disorders.This study is to investigate whether exist the relationship between sleep disorder and circadian rhythm of patients with TBI or not and focus the study on the potential of the host-microbiota interaction in regulating sleep disorder.
To examine efficacy of combined unimanual and bimanual intensive therapy in children with unilateral brain injury. A key question in hemiplegia therapy is whether the affected hand should be trained alone or in tandem with the other hand. In constraint-induced movement therapy (CIMT), a participant's less-affected upper extremity is restricted with a sling, cast, or mitt, while the participant actively uses the affected arm and hand in skill-based therapeutic activities. Bimanual therapy, in contrast, engages both hands in therapeutic movement. Since constraint and bimanual therapy target different aspects of hand use, they could have synergistic effects on hand function when given in combination.
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.
Extremely low birth weight (ELBW), birth weight less than or equal to 1000 g, infants are at high risk for developing brain injury in the first week of life. Intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL) are the most common injuries in this group of infants. Their incidence is inversely proportional to gestational age (GA) and birth weight (BW). These lesions are associated with neurodevelopmental delay, poor cognitive performance, visual and hearing impairment, epilepsy, and cerebral palsy; and instability of systemic hemodynamics during transition from intra- to extra-uterine life and during the early neonatal period is believed to be at their genesis. While the incidence of ultrasound- diagnosed cystic PVL has decreased dramatically over the last 2 decades, diffuse PVL detected by magnetic resonance imaging (MRI) is still prevalent in survivors of neonatal intensive care. Moreover, PVL, even when non-cystic, is associated with decreased cortical complexity and brain volume and eventual neurocognitive impairment. Currently, clinicians lack the tools to detect changes in cerebral perfusion prior to irreversible injury. Unfortunately, the incidence of brain injury in ELBW infants has remained relatively stable. Once translated to the bedside, the goal of this research is to develop a monitoring system that will allow researchers to identify infants most at risk for IVH and PVL and in the future, intervention studies will be initiated to use the changes in cerebral perfusion to direct hemodynamic management. The purpose of this study is to first understand the physiology of brain injury and then to eventually impact the outcomes in this high-risk group of infants by assessing the ability of the diastolic closing margin (DCM), a non-invasive estimate of brain perfusion pressure, to predict hemorrhagic and ischemic brain injury in ELBW infants. The information collected for this study will help develop algorithms or monitoring plans that will maintain the appropriate brain perfusion pressure and thereby, prevent severe brain injury.
We will determine the incidence and magnitude of cerebral desaturation in TBI. Adult patients (18 years and older) admitted to the Surgical/Trauma Intensive Care Unit (ICU) at the Health Sciences Center with a severe TBI will have cerebral oximetry monitoring instituted within 12 hours of admission and continuing for 72 hours after placement. Decreases in regional cerebral oxygenation will be correlated with ICU hemodynamic parameters including mean arterial pressure, intracranial pressure, and arterial oxygen and carbon dioxide tension.
The GASPAR trial is a pragmatic, parallel-arms, single-center, non-blinded, superiority randomized control trial in neurorehabilitation. The main objective is to test whether a 4 weeks gait rehabilitation program that uses augmented reality is superior to a conventional treadmill training program of equivalent intensity. Baseline assessments precede allocation, which consists in blocking randomization (2:1 ratio) with stratification according to the disease etiology. Post-intervention assessments serve to compare the short-term efficacy of the intervention between the two groups. Three months after discharge, follow-up assessments take place to detect potential long-term effects.
