Persistent post-concussion symptoms (PPCS) occur frequently after mild traumatic brain injury (mTBI). The identification of patients at risk for poor outcome remains challenging since valid prediction models are missing. The objectives of the current study were to assess the quality and clinical value of prediction models for PPCS , and to develop a new model based on the synthesis of existing models and addition of complaints at emergency department (ED). MTBI patients (Glasgow Coma Scale score 13-15) were prospectively recruited from three Dutch level I trauma centers between 2013-2015 in the UPFRONT study...

Previous studies have shown that isosteviol sodium (STVNa) protects against permanent cerebral ischemia injury by inhibition of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-mediated inflammatory responses. Overwhelming evidence shows that toll-like receptors (TLRs) are the upstream regulators of NF-κB. On the basis of the similarity of the pathology caused by traumatic brain injury (TBI) and stroke, we speculated that STVNa may have a therapeutic effect against TBI through regulation of the TLRs/NF-κB signaling-mediated inflammatory response...

BACKGROUND: Traumatic brain injury (TBI) represents a significant burden of care for acute surgical services, particularly in the absence of on-site neurosurgical cover or sufficient post-acute rehabilitation facilities. We examine factors contributing to TBI, prolonged lengths of stay (LoS) and implications for hospital resources. Long-term outcomes are assessed. METHODS: This is a retrospective cohort study of patients admitted to a regional trauma unit with TBI from 2008 to 2013...

Astroglia are well known for their role in propagating secondary injury following brain trauma. Modulation of this injury cascade, including inflammation, is essential to repair and recovery. Mesenchymal stromal cells (MSCs) have been demonstrated as trophic mediators in several models of secondary CNS injury, however, there has been varied success with the use of direct implantation due to a failure to persist at the injury site. To achieve sustained therapeutic benefit, we have encapsulated MSCs in alginate microspheres and evaluated the ability of these encapsulated MSCs to attenuate neuro-inflammation...

Objectives: Diffuse axonal injury is one of the major causes of unconsciousness, profound neurologic deficits and persistent vegetative state after head trauma. In recent years, MR imaging has been gaining popularity as an adjunctive imaging method in patients with DAI. Our study aims to assess the relative diagnostic and prognostic capability of various MRI sequences. Patients and Methods: Retrospective observational study done in 1 year duration on 30 DAI patients...

Introduction: Posterior fossa extradural hematoma (PFEDH) is rare among the traumatic brain injury and represent about 4-7% cases of all EDHs. This rare condition is rapidly fatal unless identified and intervened timely. Because of limited space in posterior fossa, comparatively small volume can cause clinical deterioration. Early diagnosis by cranial computed tomography and emergent evacuation is vital for a good outcome. Materials and Methods: This study was conducted at Level I trauma center at All India Institute of Medical Sciences, New Delhi, India...

In developing countries, during the harvest season, winnower blade injuries occur very frequently in children and results in lifelong disability. Nine children were managed during 1 month, all resulting due to winnower blade induced craniofacial trauma. PubMed search for "fan blade injury" showed two case series and three case reports. In our study, 88% had compound depressed fracture; brain matter leak in 56%, cerebrospinal fluid (CSF) leak alone in 22%. 66.7% had injury involving the frontal bone...

Glutamate excitotoxicity, characterized as excessive glutamate stress, is considered to be involved in cerebral ischaemia, brain trauma, and neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease. Glutamate homeostasis disruption was highlighted in Mn neurotoxicity caused by high levels of Mn. Astrocytes, accounting for approximately 50% of the neuronal cells in the central nervous system and maintain glutamate homeostasis, are sensitive to neurotoxicity induced by Mn exposure. Astrocytes are tightly coupled with gap junctions (GJ), which are comprised of connexins, mainly connexin43 (Cx43)...

Past and recent attempts at devising objective biomarkers for traumatic brain injury (TBI) in both blood and cerebrospinal fluid have focused on abundance measures of time-dependent proteins. Similar independent determinants would be most welcome in diagnosing the most common form of TBI, mild TBI (mTBI), which remains difficult to define and confirm based solely on clinical criteria. There are currently no consensus diagnostic measures that objectively define individuals as having sustained an acute mTBI. Plasma metabolomic analyses have recently evolved to offer an alternative to proteomic analyses, offering an orthogonal diagnostic measure to what is currently available...

OBJECTIVE An implicit expectation of the pioneers of trauma system design was that high clinical volume at select centers could lead to superior outcomes. There has been little study of the regionalization of pediatric craniospinal trauma care, and whether it continues to trend in the direction of regionalization is unknown. The motivating hypothesis for this study was that trauma system design in the United States is proceeding on a rational basis, producing hospital caseloads that are increasing over time and, because of geographic siting appropriate to the needs of catchment areas, in an increasingly uniform manner...

Antonio Inserra
Ayahuasca ingestion modulates brain activity, neurotransmission, gene expression and epigenetic regulation. N,N -Dimethyltryptamine (DMT, one of the alkaloids in Ayahuasca) activates sigma 1 receptor (SIGMAR1) and others. SIGMAR1 is a multi-faceted stress-responsive receptor which promotes cell survival, neuroprotection, neuroplasticity, and neuroimmunomodulation. Simultaneously, monoamine oxidase inhibitors (MAOIs) also present in Ayahuasca prevent the degradation of DMT. One peculiarity of SIGMAR1 activation and MAOI activity is the reversal of mnemonic deficits in pre-clinical models...

OBJECTIVES: This was a 27-year study of a cohort of 5708 patients who had sustained maxillofacial fractures. Our purpose was to present the etiology, mechanism of trauma, site, and concomitant injuries that led to visual loss. We hypothesize that fractures caused by high-energy impact of the midface may be associated with blindness. A discussion of the treatment approaches is also included. STUDY DESIGN: The study included 5708 patients who had sustained a maxillofacial fracture during the years 1985-2012...

Attention impairments are common symptoms of posttraumatic stress disorder (PTSD); however, the nature of these impairments remains elusive. Attention impairment may arise as the result of either excessive response to task-irrelevant stimuli or reduced response to task-relevant information. To test the association between PTSD and response to task-relevant and task-irrelevant stimuli, we used a 3-tone novelty auditory oddball task (AOD). We hypothesized that participants with PTSD relative to trauma controls would have less response during novelty processing in the dorsolateral prefrontal cortex (dlPFC) and the anterior cingulate cortex, as well as less response in the dlPFC and the orbitofrontal cortex during target detection...

The objectives were to investigate the frequency of return-to-work (RTW) one year after severe traumatic brain injury (sTBI: Glasgow Coma Scale, GCS 3-8) and to identify which demographic and injury-related characteristics and neurocognitive factors are associated with RTW. This study is part of a prospective national study on sTBI conducted in all four Norwegian Trauma Referral Centres, including patients aged >15 years over a period of three years (n = 378). For the purpose of this study, only pre-employed individuals of working age (16 to 67 years) were investigated for RTW (n = 143), and of these, 104 participants underwent neuropsychological testing...

The cerebellum plays a key role not only in motor function but also in affect and cognition. Although several psychopathological disorders have been associated with overall cerebellar dysfunction, it remains unclear whether different regions of the cerebellum contribute uniquely to psychopathology. Accordingly, we compared seed-based resting-state functional connectivity of the anterior cerebellum (lobule IV-V), of the posterior cerebellum (Crus I), and of the anterior vermis across posttraumatic stress disorder (PTSD; n = 65), its dissociative subtype (PTSD + DS; n = 37), and non-trauma-exposed healthy controls (HC; n = 47)...

To develop an outcome-based NeuroImaging Radiological Interpretation System (NIRIS) for acute traumatic brain injury (TBI) patients that would standardize the interpretation of non-contrast head CTs and consolidate imaging findings into ordinal severity categories that would inform specific patient management actions and that could be used as a clinical decision support tool. We retrospectively identified all patients transported to our emergency department by ambulance or helicopter, for whom a trauma alert was triggered per established criteria and who underwent a non-contrast head CT due to suspicion of TBI, between November 2015 and April 2016...

The belief that the spinal cord is hardwired is no longer tenable. Like the rest of the CNS, the spinal cord changes during growth and aging, when new motor behaviours are acquired, and in response to trauma and disease. This paper describes a new model of spinal cord function that reconciles its recently appreciated plasticity with its long recognized reliability as the final common pathway for behaviour. According to this model, the substrate of each motor behaviour comprises brain and spinal plasticity: the plasticity in the brain induces and maintains the plasticity in the spinal cord...
