Traumatic brain injury

INTRODUCTION: Evaluations of clinical outcomes in service members with mild traumatic brain injury (TBI) sustained in combat have largely focused on neurobehavioral and somatic symptoms, neurocognitive functioning, and psychological/psychiatric health. Questions remain regarding other domains, such as gross or fine motor abilities, that could be impacted and are mission-critical to functional warfighters. MATERIALS AND METHODS: The objective of the current study was to evaluate longitudinal motor function in U...

Many clinicians believe that residual impairments due to traumatic brain injury (TBI) are static once initial recovery has plateaued. That is, the effcts of the injury are not expected to change significantly over the remainder of a person's life. This assumption has been called into question by several independent longitudinal studies showing that the long-term course of TBI may be better characterized as dynamic rather than static. Healthcare services that recognize brain injury as a chronic condition would encourage education on self-management to improve or protect health, as well as proactive healthcare that anticipates common co-morbidities...

Background : Persistent symptoms have been reported in up to 50% of the 27 million people with mild traumatic brain injuries (mTBI) every year. MRI findings are currently limited by low diagnostic and prognostic sensitivities, constraining the value of imaging in the stratification of patients following mTBI. Limbic system structures are promising brain regions in offering prognostic factors for symptom persistence following mTBI. The objective of this study was to associate volume and symmetry of limbic system structures with the presence and persistence of common symptoms in patients with mTBI...

Background/Objectives : This study explores the relationship between cognitive performance measured by the Symbol Digit Modality Test (SDMT) and the severity of self-reported head injury, traumatic brain injury (TBI), post-traumatic stress disorder (PTSD), depression, pain, and psychosocial dysfunction in a population of trauma-affected refugees. Refugees, especially those who have been subjected to torture, often face various difficulties, such as PTSD, depression and somatic disturbances (e.g., pain), which can significantly impact their day-to-day functioning...

Background/Objectives : Traumatic brain injury (TBI) is a leading cause of death and disability in children. Currently, no biological test can predict outcomes in pediatric TBI, complicating medical management. This study sought to identify brain-related micro-ribosomal nucleic acids (miRNAs) in saliva associated with moderate-to-severe TBI in children, offering a potential non-invasive, prognostic tool. Methods : A case-control design was used, enrolling participants ≤ 18 years old from three pediatric trauma centers...

Post-traumatic cerebral venous sinus thrombosis (ptCVST) often remains underdiagnosed due to the non-specific nature of clinical signs, commonly mimicking severe traumatic brain injury (TBI) manifestations. Early recognition of this rare and potentially life-threatening complication is crucial for the effective management of severe TBI patients in Intensive Care. The present study reports the case of a 66-year-old male who was transferred to the emergency department due to moderate TBI. Initial emergency brain computed tomography (CT) scans revealed certain traumatic lesions, not necessitating any urgent neurosurgical intervention...

Traumatic brain injury (TBI) is the leading cause of traumatic death worldwide and is a public health problem associated with high mortality and morbidity rates, with a significant socioeconomic burden. The diagnosis of brain injury may be difficult in some cases or may leave diagnostic doubts, especially in mild trauma with insignificant pathological brain changes or in cases where instrumental tests are negative. Therefore, in recent years, an important area of research has been directed towards the study of new biomarkers, such as micro-RNAs (miRNAs), which can assist clinicians in the diagnosis, staging, and prognostic evaluation of TBI, as well as forensic pathologists in the assessment of TBI and in the estimation of additional relevant data, such as survival time...

Direct neuronal reprogramming is a promising approach to replace neurons lost due to disease via the conversion of endogenous glia reacting to brain injury into neurons. However, it is essential to demonstrate that the newly generated neurons originate from glial cells and/or show that they are not pre-existing endogenous neurons. Here, we use controls for both requirements while comparing two viral vector systems (Mo-MLVs and AAVs) for the expression of the same neurogenic factor, the phosphorylation-resistant form of Neurogenin2...

Traumatic brain injury (TBI) has been found to be associated with certain peripheral organ injuries; however, a few studies have explored the chronological influences of TBI on multiple organs and the systemic effects of therapeutic interventions. Particularly, high-mobility group box 1 (HMGB1) is a potential therapeutic target for TBI; however, its effects on peripheral organs remain unclear. Therefore, this study aimed to determine whether severe TBI can lead to multiple organ injury and how HMGB1 inhibition affects peripheral organs...

OBJECTIVE: Predicting high-value care outcomes is crucial in managing pediatric traumatic brain injuries (TBIs), where timely and accurate prognostication can significantly influence treatment decisions and resource allocation. This study aimed to enhance understanding of how well scoring systems such as the Trauma and Injury Severity Score (TRISS) can forecast high-value care outcomes. Furthermore, the authors compared the predictive power of TRISS with the routinely used Injury Severity Score (ISS)...

OBJECTIVE: Despite the growing literature on sport-related concussion (SRC) in high school and collegiate athletes, the understanding of how outcomes can vary in child athletes younger than 12 years of age remains limited. Therefore, the authors sought to compare injury characteristics and recovery in 8- to 12-year-old athletes with those of 13- to 17-year-old athletes following SRC. METHODS: A single-institution retrospective cohort study was undertaken including 8- to 12-year-old and 13- to 17-year-old athletes seen at a regional SRC between November 2017 and January 2022...

Subjective cognitive decline (SCD) is one of the most important early onset symptoms of Alzheimer's Disease. Previous studies consistently reported that SCD is associated with quality of life, socio-economic factors, and related health comorbidities. However, the impact of veteran status on SCD has been little investigated. This study conducted a cross-sectional study to address disproportionate effects in subjective cognitive decline between veterans and non-veterans in the United States. Propensity score matching (PSM) was applied in this observational study to achieve covariate balancing and reduce selection bias, providing a more accurate estimate of the isolated effect of veteran status on SCD...

BACKGROUND: Veterans Affairs and the Department of Defense (DOD) acknowledge that nutrition may be a modifier of mild traumatic brain injury (TBI) sequelae. Military clinicians are considering nutritional supplements and dietary interventions when managing patients with mild TBI. Therefore, clinicians should be familiar with the current evidence for nutritional interventions in mild TBI and special considerations related to the military lifestyle. OBJECTIVE: This narrative review aims to summarize the existing evidence surrounding the role of special diets and select nutrients in mild TBI outcomes, gut microbiota changes, and special considerations for Service members and Veterans recovering from mild TBI...

BACKGROUND: Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy more frequently found in deceased former football players. CTE has heterogeneous clinical presentations with multifactorial causes. Previous literature has shown substance use (alcohol/drug) can contribute to Alzheimer's disease and related tauopathies pathologically and clinically. OBJECTIVE: To examine the association between substance use and clinical and neuropathological endpoints of CTE...

INTRODUCTION: Absence of pre-hospital coagulation tests challenges prompt management of hemostasis after trauma. The Viscoelastic Coagulation Monitor (VCM, Entegrion, Durham, NC) is a hand-held coagulation test for point-of-care. We evaluated VCM in a translational swine polytrauma model, hypothesizing that VCM correlates with a laboratory reference method, the TEG 5000 (Haemonetics, Boston, MA), and can identify coagulopathic phenotypes relevant to trauma. Our secondary hypothesis was that pre-warming of VCM disposable test cartridges using a heating plate versus pre-warming of cartridges by carrying the cartridge in the user's pocket does not significantly alter results...

In the presented clinical observation of complex therapy of severe combined trauma: severe brain contusion, subarachnoid hemorrhage, closed fracture of the occipital bone, closed compression fracture of ThVI -ThVIII vertebral bodies, contusion of the lungs and kidneys, blunt abdominal trauma and closed fracture of both bones of the right leg in lower third with displacement) in a teenager after an accident, the need for dynamic introscopic examination of the patient is shown for timely detection of abnormalities in the state of brain structures and correction of treatment up to surgical intervention...

Trauma is a prevalent cause of coagulopathy, with traumatic brain injury (TBI) accompanied by coagulation disorders particularly linked to adverse outcomes. TBI is distinguished by minimal bleeding volume and unique injury sites, which precipitate complex coagulation disturbances. Historically, research into trauma-induced coagulopathy has primarily concentrated on the molecular biology and pathophysiology of endogenous anticoagulation and inflammation. Nonetheless, recognizing that cells are the fundamental units of structure and function in all living organisms, the present review aimed to distill our understanding of coagulopathy post-TBI by elucidating the intricate cellular mechanisms involving endothelial cells, neutrophils and platelets...
