INTRODUCTION: Traumatic brain injury (TBI) is a public health problem. It is a pathology that causes significant mortality and disability in Colombia. Different calculators and prognostic models have been developed to predict the neurological outcomes of these patients. The Rotterdam computed tomography (CT) score was developed for prognostic purposes in TBI. We aimed to examine the accuracy of the prognostic discrimination and prediction of mortality of the Rotterdam CT score in a cohort of trauma patients with severe TBI in a university hospital in Colombia...

The innate inflammatory response contributes to secondary injury in brain trauma and other disorders. Metabolic factors such as caloric restriction, ketogenic diet, and hyperglycemia influence the inflammatory response, but how this occurs is unclear. Here, we show that glucose metabolism regulates pro-inflammatory NF-κB transcriptional activity through effects on the cytosolic NADH:NAD(+) ratio and the NAD(H) sensitive transcriptional co-repressor CtBP. Reduced glucose availability reduces the NADH:NAD(+) ratio, NF-κB transcriptional activity, and pro-inflammatory gene expression in macrophages and microglia...

Brain trauma is often associated with severe morbidity and is a major public health concern. Even when injury is mild and no obvious anatomic disruption is seen, many individuals suffer disabling neuropsychological impairments such as memory loss, mood dysfunction, substance abuse, and adjustment disorder. These changes may be related to subtle disruption of neural circuits as well as functional changes at the neurotransmitter level. In particular, there is considerable evidence that dopamine (DA) physiology in the nigrostriatal and mesocorticolimbic pathways might be impaired after traumatic brain injury (TBI)...

Fat embolism syndrome (FES) is a rare syndrome caused by embolization of fat particles into multiple organs including the brain. It typically manifests with petechial rash, deteriorating mental status, and progressive respiratory insufficiency, usually occurring within 24-48 h of trauma with long-bone fractures or an orthopedic surgery. The diagnosis of FES is based on clinical and imaging findings, but requires exclusion of alternative diagnoses. Although there is no specific treatment for FES, prompt recognition is important because it can avoid unnecessary interventions and clarify prognosis...

BACKGROUND: Brain-dead pediatric donors have always been the focus of attention because of the higher quality, utility, and possibility of their organ donation. However, donors under the age of 5 years always necessitate making more challenging management efforts, which are not clearly implied in most parts of the guidelines. METHODS: The data obtained from 79 brain-dead pediatric donors of the Organ Procurement Unit of Masih Daneshvari Hospital, Tehran, Iran, were assessed...

PURPOSE: There is a lack of association between coagulation biomarkers and long-term mortality in severe trauma. We aimed to investigate the association between coagulation biomarkers on admission and outcome of late stage of trauma. METHODS: This retrospective observational study included patients admitted with severe trauma between 2012 and 2015. We used the area under the receiver operating characteristic curve (AUROC) of coagulation biomarkers to determine 28-day mortality...

Cardiac arrest is the most common cause of death in North America. An organized bundle of neurocritical care interventions can improve chances of survival and neurological recovery in patients who are successfully resuscitated from cardiac arrest. Therefore, resuscitation following cardiac arrest was chosen as an Emergency Neurological Life Support protocol. Key aspects of successful early post-arrest management include: prevention of secondary brain injury; identification of treatable causes of arrest in need of emergent intervention; and, delayed neurological prognostication...

BACKGROUND: The Glasgow Coma Scale (GCS) score is the most widely utilized measure of traumatic brain injury (TBI) severity. Currently, the arrival GCS motor score (mGCS) is used in risk-adjustment models for external benchmarking of mortality. However, there is evidence that the highest mGCS in the first 24 hours after injury might be a better predictor of death. Our objective was to evaluate the impact of including highest mGCS on the performance of risk-adjustment models and subsequent external benchmarking results...

PREMISE: Trigeminal neuralgia is a severe facial pain disorder that has been studied for decades. Classical trigeminal neuralgia (CTN) is either idiopathic or caused by neurovascular compression. The related painful trigeminal neuropathies are often secondary to other causes, such as multiple sclerosis or trauma. PROBLEM: Therapies for trigeminal neuralgia and neuropathy have often been pharmacologic or surgical. Pharmacologic therapies are not effective in some cases and often cause side effects, some substantial...

This study compared CSF levels of MAP-2 from adult patients with severe TBI to uninjured controls over ten days, and examined the relationship between MAP-2 concentrations and acute clinical and radiologic measures of injury severity along with mortality at 2-weeks and over 6-months. This prospective study, conducted at two Level 1 Trauma Centers, enrolled adults with severe TBI (GCS ≤8) requiring a ventriculostomy as well as controls. Ventricular CSF was sampled from each patient at 6, 12, 24, 48, 72, 96, 120, 144, 168, 192, 216 and 240 hours following TBI and analyzed via ELISA for MAP-2 (ng/ml)...

BACKGROUND: Previous studies demonstrated decreased brain microstructure integrity in people that were exposed to extreme life stress but did not meet posttraumatic stress disorder (PTSD) diagnostic criteria. It is unclear how the brain recovers from traumatic stress in these trauma-exposed non-PTSD people (TENP). METHODS: Twenty-two TENP individuals were recruited from the most affected area of Wenchuan quake, and scanned twenty-five days after the quake and at a two-year follow-up...

Post-traumatic stress disorder (PTSD) is a condition that develops after an individual has experienced a major trauma. This psychopathological response to traumatic stressors induces learning and memory deficits in rats. Oleuropein (OLE), a major compound in olive leaves, has been reported to possess several pharmacological properties, including anti-cancer, anti-diabetic, anti-atherosclerotic and neuroprotective activities. However, the cognitive effects of OLE and its mechanism of action have remained unclear in PTSD...

OBJECTIVE: Neurobiological research has traditionally focused on vulnerability rather than on resilience to severe stress. So far, only a few neuroimaging studies examining resilience have used designs that allow disentangling of the neural correlates of resilience from those related to psychopathology or trauma-exposure. The aim of this study was to identify structural brain correlates of resilience, and their correlations with behavioral measures. METHOD: MRI scanning was performed in three groups of police officers: (1) a resilient group (N=29; trauma-exposed, no psychopathology), (2) a vulnerable group (N=33; trauma-exposed, psychopathology), and (3) a control group (N=19; no trauma, no psychopathology)...

Few studies have examined the effect of varying the assault perpetrator on expectations of outcome from mild TBI. Using a cross sectional between groups design, individuals with no history of mild TBI were randomly allocated to one of two vignette conditions. The vignette depicted a mild TBI with fixed injury parameters and a different assault perpetrator (partner, n = 27; or stranger, n = 27). The participants were instructed to imagine that they had been injured as per the depiction, and then to anticipate the injury consequences 6-months later...

BACKGROUND: No definitive evidence exists on how intracranial hypertension should be treated in patients with traumatic brain injury (TBI). It is therefore likely that centers and practitioners individually balance potential benefits and risks of different intracranial pressure (ICP) management strategies, resulting in practice variation. The aim of this study was to examine variation in monitoring and treatment policies for intracranial hypertension in patients with TBI. METHODS: A 29-item survey on ICP monitoring and treatment was developed on the basis of literature and expert opinion, and it was pilot-tested in 16 centers...
