Transcriptional Factors and Protein Biomarkers as Target Therapeutics in Traumatic Spinal Cord and Brain Injury.

Traumatic injury to the spinal cord (SCI) and brain (TBI) are serious health problems and affect many people every year throughout the world. These devastating injuries are affecting not only patients but also their families socially as well as financially. SCI and TBI lead to neurological dysfunction besides continuous inflammation, ischemia, and necrosis followed by progressive neurodegeneration. There are well-established changes in several other processes such as gene expression as well as protein levels that are the important key factors to control the progression of these diseases. We are not yet able to collect enough knowledge on the underlying mechanisms leading to the altered gene expression profiles and protein levels in SCI and TBI. Cell loss is hastened by the induction or imbalance of pro- or anti-inflammatory expression profiles and transcription factors for cell survival after or during trauma. There is a sequence of events of dysregulation of these factors from early to late stages of trauma that opens a therapeutic window for new interventions to prevent/restrict the progression of these diseases. There has been increasing interest in the modulation of these factors for improving the patient’s quality of life by targeting both SCI and TBI. Here, we review some of the recent transcriptional factors and protein biomarkers that have been developed and discovered in the last decade in the context of targeted therapeutics for SCI and TBI patients.

FOUR Score sebagai Alternatif dalam Menilai Derajat Keparahan dan Memprediksi Mortalitas pada Pasien Cedera Otak Traumatik yang Diintubasi

The ideal consciousness scoring scale must be linear, reliable, valid, and user-friendly. There is a need to develop and validate a scale to quickly evaluate the level of consciousness, the severity of the disease, and the prognosis of morbidity and mortality. Glasgow Coma Scale (GCS) is the most commonly used tool to assess the level of consciousness and is considered the gold standard. However, GCS has several limitations, such as inability to evaluate verbal components in intubated patients. To overcome these challenges, researchers developed the Full Outline of UnResponsiveness (FOUR) score. FOUR scores is a clinical grading scale to assess the altered state of consciousness. FOUR scores is simpler and able to provide better information, especially in intubated-traumatic brain injury (TBI) patients. Some studies showed that GCS and FOUR scores have the high predictive value in predicting not only the mortality of trauma patients but also the outcome of discharged patients. A multicentre study showed that FOUR scores and GCS do not differ in predicting inpatient mortality. This study suggested that the FOUR scores could be a better diagnostic tool for assessing brainstem reflexes and breathing patterns. Unfortunately, some studies have found conflicting results between GCS and FOUR scores in predicting patient outcomes. These contradictions suggest the need to conduct more studies. Therefore, this literature review will compare GCS and FOUR scores in predicting mortality of TBI patients.

THE NEUROPSYCHOLOGY OF METAPHORS IN PATIENTS AWAKENED FROM POST-TRAUMATIC COMA

Metaphor simply is defined as a verbal construct with two referents: one literal, based on the ordinary, concrete meanings of the word or words involved, and the other metaphorical, that is one derived from an implicit analogy between the literal referent and some other phenomenon, usually an abstraction that is implied, but not named. The aim of this paper is a description of the neuropsychology of metaphors in patients awakened from post-traumatic coma. A group of 34 patients awakened from post-traumatic coma and treated at the Reintegrative and Teaching Centre of the Polish Neuropsychological Society, Poland during the period 2017- 2019 participated in this study. This group included 15 women and 17 men, with an average age of 31.2 ± 8.72 years; as a group, the women were somewhat older (32.6 ± 9.79 vs. 31.1 ± 9.18). We recorded the patients’ utterances with the use of video record- ings of open-ended conversations, and made occasional efforts to introduce proverbs, idioms, and other metaphors into their conversation, but this was done on an impromptu basis. The analysis of recordings of 100 randomly selected statements obtained from each patient revealed the presence of 4 types of errors: (1) non-comprehension, i.e. the listener’s inability to comprehend the meaning of the metaphor used by the speaker, as indicated by the lack of an adequate response, an expression of puzzlement, or a question as to the meaning of the metaphor used by the speaker; (2) concretization, which occurs when the listener reacts to the literal meaning of the word, phrase, or sentence, rather than its metaphorical referent; (3) misapplication, when the speaker uses a familiar metaphor in an inappropriate context; (4) the use of incomprehensible or bizarre metaphors by the speaker, so that the intended meaning is difficult or impossible for the listener to ascertain. On many occasions, however, the gist of the metaphor emerged at some later point in the discourse, despite the surface problems. It was found that the TBI patients we studied showed a marked tendency in spontaneous conversation to concretize or misunderstand the metaphors used by others, and to use inappropriate or bizarre metaphors in their own speech. On many occasions, however, the gist of the metaphor emerged at some later point in the discourse, despite the surface problems.

Inter-facility transfer of patients with traumatic intracranial hemorrhage and GCS 14–15: The pilot study of a screening protocol by neurosurgeon to avoid unnecessary transfers

We sought to evaluate feasibility and cost-reduction potential of a pilot screening program involving neurosurgeon tele-consultation for inter-facility transfer decisions in TBI patients with GCS 14–15 and abnormal CT head at a community hospital. The authors performed a retrospective comparative analysis of two patient cohorts during the pilot at a large hospital system from 2015 to 2017. In “screened” patients (n = 85), images and examination were reviewed remotely by a neurosurgeon who made recommendations regarding transfer to a level 1 trauma center. In the “unscreened” group (n = 39), all patients were transferred. Baseline patient characteristics, outcomes, and costs were reviewed. Patient demographics were similar between cohorts. Traumatic subarachnoid hemorrhage was more common in screened patients (29.4% vs 12.8%, P = 0.02). The presence of midline shift >5 mm was comparable between groups. Among screened patients, 5 were transferred (5.8%) and one required evacuation of chronic subdural hematoma. In unscreened patients, 7 required evacuation of subdural hematoma. None of the screened patients who were not transferred deteriorated. Screened patients had significantly reduced average total cost compared to unscreened patients ($2,003 vs. $4,482, P = 0.03) despite similar lengths of stay (2.6 vs. 2.7 days, P = 0.85). In non-surgical patients, costs were less in the screened group ($2,025 vs. $2,939), although statistically insignificant (P = 0.38).In this pilot study, remote review of images and examination by a neurosurgeon was feasible to avoid unnecessary transfer of patients with traumatic intracranial hemorrhage and GCS 14–15. The true potential in cost-reduction will be realized in system-wide large-scale implementation.

Outcomes After Tracheostomy in Patients with Severe Acute Brain Injury: A Systematic Review and Meta-Analysis.

To synthesize reported long-term outcomes in patients undergoing tracheostomy after severe acute brain injury (SABI). We systematically searched PubMed, EMBASE, and Cochrane Library for studies in English, German, and Spanish between 1990 and 2019, reporting outcomes in patients with SABI who underwent tracheostomy. We adhered to the preferred reporting items for systematic reviews and meta-analyses guidelines and the meta-analyses of observational studies in epidemiology guidelines. We excluded studies reporting on less than 10 patients, mixed populations with other neurological diseases, or studies assessing highly select subgroups defined by age or procedures. Data were extracted independently by two investigators. Results were pooled using random effects modeling. The primary outcome was long-term functional outcome (mRS or GOS) at 6-12months. Secondary outcomes included hospital and long-term mortality, decannulation rates, and discharge home rates. Of 1405 studies identified, 61 underwent full manuscript review and 19 studies comprising 35,362 patients from 10 countries were included in the meta-analysis. The primary outcome was available from five studies with 451 patients. At 6-12months, about one-third of patients (30%; 95% confidence interval [CI] 17-48) achieved independence, and about one-third survived in a dependent state (36%, 95% CI 28-46%). The pooled short-term mortality for 19,048 patients was 12%, (95% CI 9-17%) with no significant difference between stroke (10%) and TBI patients (13%), and the pooled long-term mortality was 21% (95% CI 11-36). Decannulation occurred in 79% (95% CI 51-93%) of survivors. Heterogeneity was high for most outcome assessments (I2 > 75%). Our findings suggest that about one in three patients with SABI who undergo tracheostomy may eventually achieve independence. Future research is needed to understand the reasons for the heterogeneity between studies and to identify those patients with promising outcomes as well as factors influencing outcome.

Traumatic Brain Injury: Effect of Litigation Status on Executive Functioning—A Pilot Study

AbstractTraumatic brain injury (TBI) is associated with a wide range of physiological, behavioral, emotional, and cognitive sequelae. Litigation status is one of the many factors that has an impact on recovery. The aim of this study was to compare executive functions, postconcussion, and depressive symptoms in TBI patients with and without litigation. A sample of 30 patients with TBI, 15 patients with litigation (medicolegal case [MLC]), and 15 without litigation (non-MLC) was assessed. The tools used were sociodemographic and clinical proforma, executive function tests, Rivermead Post-Concussion Symptom Questionnaire, and Beck Depression Inventory. Assessment revealed that more than 50% of patients showed deficits in category fluency, set shifting, and concept formation. The MLC group showed significant impairment on verbal working memory in comparison to the non-MLC group. The performance of both groups was comparable on tests of semantic fluency, visuospatial working memory, concept formation, set shifting, planning, and response inhibition. The MLC group showed more verbal working memory deficits in the absence of significant postconcussion and depressive symptoms on self-report measures.

A mixed methods randomised feasibility trial investigating the management of benign paroxysmal positional vertigo in acute traumatic brain injury

BackgroundTraumatic brain injury (TBI) is the leading cause of long-term disability in working age adults. Recent studies show that most acute TBI patients demonstrate vestibular features of dizziness and imbalance, often from combined peripheral and central vestibular dysfunction. Effective treatment for vestibular impairments post-TBI is important given its significant adverse impact upon quality of life and employment prospects. The most frequent peripheral vestibular disorder in acute TBI is benign paroxysmal positional vertigo (BPPV), affecting approximately half of acute cases. Although there is effective treatment for idiopathic BPPV, there are no high-quality clinical data for post-TBI BPPV regarding its prevalence, natural history, which treatment is most effective and when is the best time to treat. In particular, observational studies suggest post-TBI BPPV may be recurrent, indicating that hyperacute treatment of BPPV may be futile. Given the potential hurdles and the lack of accurate post-TBI BPPV data, the current study was designed to provide information regarding the feasibility and optimal design of future large-scale prospective treatment studies that would compare different interventions and their timing for post-TBI BPPV.MethodA multi-centre randomised mixed methods feasibility study design was employed. We aim to recruit approximately 75 acute TBI patients across a range of clinical severities, from three major trauma centres in London. Patients will be randomised to one of three treatment arms: (1) therapist-led manoeuvres, (2) patient-led exercises and (3) advice. Participants will be re-assessed by blinded outcome assessors at 4 and 12 weeks. Acceptability of the intervention will be obtained by patient interviews at the end of their treatment and therapist interviews at the end of the study. Primary outcomes relate to feasibility parameters including recruitment and retention rates, adverse events and intervention fidelity. We will also aim to provide a more accurate estimate of the prevalence of BPPV in TBI cases on the trauma ward.DiscussionThe multi-centre nature of our feasibility study will inform the design of a future prospective treatment trial of BPPV in acute TBI. Important parameters we will obtain from this study, key for designing a future prospective treatment study, include estimating the prevalence of BPPV in TBI patients admitted to UK major trauma wards, and elucidating both patient and care-provider barriers in delivering BPPV treatment.Trial registrationISRCTN, ISRCTN91943864.

Neuroinflammatory Biomarkers Associated With Mild Traumatic Brain Injury History in Special Operations Forces Combat Soldiers

Special Operations Forces (SOF) combat soldiers are frequently exposed to blast and blunt neurotrauma, most often classified as mild traumatic brain injury (mTBI). Repetitive mTBI may increase the risk of developing long-term neurological sequelae. Identifying changes in neuroinflammatory biomarkers before chronic conditions emerge could serve as preliminary evidence of developing neuropathology. To determine the effects of mTBI history, lifetime mTBI incidence, and recency on blood biomarker concentrations of axonal protein neurofilament light (NfL), glycolytic enzyme neuron-specific enolase (NSE), astrocyte-expressed S100 calcium-binding protein B (S100B), and neurotrophic cytokine interleukin-6 (IL-6) in healthy, active duty SOF combat soldiers. Self-reported mTBI history/recency and fasted blood samples were collected in this cross-sectional study of 104 asymptomatic SOF combat soldiers. Biomarker concentrations were quantified using commercial enzyme-linked immunosorbent assays. Mann-Whitney U and Kruskal-Wallis tests were used to compare groups. Post hoc tests with appropriate corrections were conducted as warranted. Soldiers with mTBI history had higher NSE concentrations than those without (z = -2.60, P = .01). We also observed significant main effects of lifetime mTBI incidence on NSE (χ(3) = 9.52, P = .02) and S100B (χ(3) = 8.21, P = .04) concentrations and a significant main effect of mTBI recency on NfL concentration (χ(2) = 6.02, P = .049). The SOF combat soldiers with mTBI history had increased NSE. Longitudinal studies in this population are needed due to between-subject heterogeneity in biomarker concentrations. The NfL concentrations in our SOF combat soldiers-regardless of mTBI history or recency-were similar to values previously reported in civilian acute TBI patients.

Management of Traumatic Intracranial Hemorrhage on Anticoagulant Regiment: A Literature Review

Oral anticoagulant and antiplatelet are often prescribed in clinical practice. These drugs are mainly consumed by geriatric patients to prevent or treat cerebrovascular, systemic embolism, or heart condition. Managing anticoagulated TBI patients is a challenging task for surgeons. This study aims to review available literatures regarding anticoagulated TBI patients and to suggest a treatment algorithm for such cases. Based on several retrospective and prospective studies, it might be wasteful to do a routine follow-up CT scan on anticoagulated TBI patients. The risk of new lesion development or presenting lesion progression seems to be especially low among patients with negative initial CT scan. We suggest to reserve repeat CT scan for patients with evident neurological deterioration. Tighter observation for anticoagulated patients with positive initial CT scan might be useful. Anticoagulation reversal is recommended by the American College of Cardiology, but some studies reported that reversal should be directed by INR. Acute antiplatelet cessation is still controversial for aspirin, but it is advised for clopidogrel. Preoperative management of both anticoagulant and antiplatelet should take into account the bleeding risk of the surgical procedure. Blind cessation and reversal of anticoagulant and/or antiplatelet might delay the timing of surgery and thus would better be avoided

A-189 Exploring the Effects of EEG Neurofeedback Training on Verbal Episodic Memory in a TBI Sample

Abstract Objective Traumatic brain injuries (TBI) are commonly characterized by neural changes that impair physical, behavioral, and cognitive functioning across diverse ages and demographics. Cognitive complaints frequently include memory difficulties, with deficits in episodic memory greatly impairing daily functioning and future planning. Although various interventions and rehabilitation techniques have been implemented for TBI, limited treatment options are available for TBI-driven memory complaints. Recent research has explored the use of neurofeedback training (NFT) to improve cognitive functioning in TBI patients, yet it remains unclear whether this intervention may be successful in improving these memory deficits. Method In this double-blind, placebo-controlled pilot study, the use of EEG neurofeedback training (NFT) on verbal episodic memory was explored in 12 veterans with TBI. Participants were randomized to active treatment or sham treatment, and they completed 20 sessions of NFT. Clinical assessments and functional magnetic resonance imaging (fMRI) data were collected pre and post treatment to measure any changes in resting-state functional connectivity or cognitive functioning. Results Findings suggest that immediate recall scores improved following active NFT, as measured by the California Verbal Learning Task-II. We also observed increased resting-state functional connectivity between the ventromedial prefrontal cortex and the inferior temporal lobe following NFT (Fig. 1), which may represent an underlying mechanism of memory improvement. Conclusions These exploratory findings may hold promise for future research on the use of NFT for memory enhancement in various populations.

Traumatic brain injury neuroelectrochemical monitoring: behind-the-ear micro-instrument and cloud application

BackgroundTraumatic Brain Injury (TBI) is a leading cause of fatality and disability worldwide, partly due to the occurrence of secondary injury and late interventions. Correct diagnosis and timely monitoring ensure effective medical intervention aimed at improving clinical outcome. However, due to the limitations in size and cost of current ambulatory bioinstruments, they cannot be used to monitor patients who may still be at risk of secondary injury outside the ICU.MethodsWe propose a complete system consisting of a wearable wireless bioinstrument and a cloud-based application for real-time TBI monitoring. The bioinstrument can simultaneously record up to ten channels including both ECoG biopotential and neurochemicals (e.g. potassium, glucose and lactate), and supports various electrochemical methods including potentiometry, amperometry and cyclic voltammetry. All channels support variable gain programming to automatically tune the input dynamic range and address biosensors’ falling sensitivity. The instrument is flexible and can be folded to occupy a small space behind the ear. A Bluetooth Low-Energy (BLE) receiver is used to wirelessly connect the instrument to a cloud application where the recorded data is stored, processed and visualised in real-time. Bench testing has been used to validate device performance.ResultsThe instrument successfully monitored spreading depolarisations (SDs) - reproduced using a signal generator - with an SNR of 29.07 dB and NF of 0.26 dB. The potentiostat generates a wide voltage range from -1.65V to +1.65V with a resolution of 0.8mV and the sensitivity of the amperometric AFE was verified by recording 5 pA currents. Different potassium, glucose and lactate concentrations prepared in lab were accurately measured and their respective working curves were constructed. Finally,the instrument achieved a maximum sampling rate of 1.25 ksps/channel with a throughput of 105 kbps. All measurements were successfully received at the cloud.ConclusionThe proposed instrument uniquely positions itself by presenting an aggressive optimisation of size and cost while maintaining high measurement accuracy. The system can effectively extend neuroelectrochemical monitoring to all TBI patients including those who are mobile and those who are outside the ICU. Finally, data recorded in the cloud application could be used to help diagnosis and guide rehabilitation.

Establishment and validation of a model for brain injury state evaluation and prognosis prediction

PurposeTraumatic brain injury (TBI) is one of the leading causes of disability and death in modern times, whose evaluation and prognosis prediction have been one of the most critical issues in TBI management. However, the existed models for the abovementioned purposes were defective to varying degrees. This study aims to establish an ideal brain injury state clinical prediction model (BISCPM). MethodsThis study was a retrospective design. The six-month outcomes of patients were selected as the end point event. BISCPM was established by using the split-sample technology, and externally validated via different tests of comparison between the observed and predicted six-month mortality in validating group. TBI patients admitted from July 2006 to June 2012 were recruited and randomly divided into establishing model group and validating model group. Twenty-one scoring indicators were included in BISCPM and divided into three parts, A, B, and C. Part A included movement, pupillary reflex and diameter, CT parameters, and secondary brain insult factors, etc. Part B was age and part C was medical history of the patients. The total score of part A, B and C was final score of BISCPM. ResultsAltogether 1156 TBI patients were included with 578 cases in each group. The score of BISCPM from validating group ranged from 2.75 to 31.94, averaging 13.64 ± 5.59. There was not statistical difference between observed and predicted mortality for validating group. The discrimination validation showed that the BISCPM is superior to international mission for prognosis and analysis of clinical trials (IMPACT) lab model. ConclusionBISCPM is an effective model for state evaluation and prognosis prediction of TBI patients. The use of BISCPM could be of great significance for decision-making in management of TBI.

Vestibular Assessment in Patients with Persistent Symptoms of Mild Traumatic Brain Injury.

The estimated worldwide incidence of TBI is 10 million cases per year. Dizziness and imbalance are two common symptoms in mild TBI (mTBI). In about 10-15% of TBI patients, these symptoms remain for a long time and may show no recovery. These persistent symptoms may relate to different factors including vestibular abnormalities. The aim of this study is a vestibular assessment of patients with persistent symptoms of mTBI by different tests including computerized dynamic posturography. 21 patients with mTBI evaluated in this study. Patients were civilians with persistent symptoms. TBI did cause by blunt force trauma (mainly from falling) in the past 6months. They had normal neurologic and musculoskeletal assessments and no temporal bone fracture. Several auditory and vestibular evaluations were performed for each patient. They included: case history, otoscopy, pure tone and speech audiometry, tympanometry, vestibular bedside examination (spontaneous nystagmus, gaze, saccade, pursuit, Dix-Hallpike maneuver, side-lying maneuver, roll, and Romberg test), cervical Vestibular Myogenic Evoked Potential (c-VEMP), Computerized Dynamic Posturography (CDP) and Dizziness Handicap Inventory (DHI). Patients showed hearing loss in 10 (47.6%) and tinnitus in 4 (19.0%) cases. In ocular motor tests, patients had the most abnormal results in the pursuit test. 6 patients also had Benign Paroxysmal Positional Vertigo (BPPV) in the posterior canal. c-VEMP showed abnormal saccular function in 14 patients. In CDP, the composite scores were decreased relative to normal populations. vestibular tests showed abnormal results in most patients. Vestibular abnormality could relate to persisting symptoms of mTBI patients.

Post-TBI splenectomy may exacerbate coagulopathy and platelet activation in a murine model

IntroductionTraumatic brain injury (TBI) induces acute hypocoagulability, subacute hypercoagulability, and persistently elevated risk for thromboembolic events. Splenectomy is associated with increased mortality in patients with moderate or severe TBI. We hypothesized that the adverse effects of splenectomy in TBI patients may be secondary to the exacerbation of pathologic coagulation and platelet activation changes. MethodsAn established murine weight-drop TBI model was utilized and a splenectomy was performed immediately following TBI. Sham as well as TBI and splenectomy alone mice were used as injury controls. Mice were sacrificed for blood draws at 1, 6, and 24 h, as well as 7 days post-TBI. Viscoelastic coagulation parameters were assessed by rotational thromboelastometry (ROTEM) and platelet activation was measured by expression of P-selectin via flow cytometry analysis of platelet rich plasma samples. ResultsAt 6 h following injury, TBI/splenectomy demonstrated hypocoagulability with prolonged clot formation time (CFT) compared to TBI alone. By 24 h following injury, TBI/splenectomy and splenectomy mice were hypercoagulable with a shorter CFT, a higher alpha angle, and increased MCF, despite a lower percentage of platelet contribution to clot compared to TBI alone. However, only the TBI/splenectomy continued to display this hypercoagulable state at 7 days. While TBI/splenectomy had greater P-selectin expression at 1-h post-injury, TBI alone had significantly greater P-selectin expression at 24 h post-injury compared to TBI/splenectomy. Interestingly, P-selectin expression remained elevated only in TBI/splenectomy at 7 days post-injury. ConclusionSplenectomy following TBI exacerbates changes in the post-injury coagulation state. The combination of TBI and splenectomy induces an acute hypocoagulable state that could contribute to an increase in intracranial bleeding. Subacutely, the addition of splenectomy to TBI exacerbates post-injury hypercoagulability and induces persistent platelet activation. These polytrauma effects on coagulation may contribute to the increased mortality observed in patients with combined brain and splenic injuries.

Accounting for Changing Structure in Functional Network Analysis of TBI Patients.

Over the last 15 years, network analysis approaches based on MR data have allowed a renewed understanding of the relationship between brain function architecture and consciousness. Application of this approach to Disorders of Consciousness (DOC) highlights the relationship between specific aspects of network topology and levels of consciousness. Nonetheless, such applications do not acknowledge that DOC patients present with a dramatic level of heterogeneity in structural connectivity (SC) across groups (e.g., etiology, diagnostic categories) and within individual patients (e.g., over time), which possibly affects the level and quality of functional connectivity (FC) patterns that can be expressed. In addition, it is rarely acknowledged that the most frequently employed outcome metrics in the study of brain connectivity (e.g., degree distribution, inter- or intra-resting state network connectivity, and clustering coefficient) are interrelated and cannot be assumed to be independent of each other. We present empirical data showing that, when the two points above are not taken into consideration with an appropriate analytic model, it can lead to a misinterpretation of the role of each outcome metric in the graph's structure and thus misinterpretation of FC results. We show that failing to account for either SC or the inter-relation between outcome measures can lead to inflated false positives (FP) and/or false negatives (FN) in inter- or intra-resting state network connectivity results (defined, respectively, as a positive or negative result in network connectivity that is present when not accounting for SC and/or outcome measure inter-relation, but becomes not significant when accounting for all variables). Overall, we find that unconscious patients have lower rates of FP and FN for within cortical connectivity, lower rates of FN for cortico-subcortical connectivity, and lower rates of FP for within subcortical connectivity. These lower rates in unconscious patients may reflect differences in their triadic closure and SC metrics, which bias the interpretations of the inter- or intra-resting state network connectivity if the SC metrics and triadic closure are not modeled. We suggest that future studies of functional connectivity in DOC patients (i) incorporate where possible SC metrics and (ii) properly account for the intercorrelated nature of outcome variables.

Hypotension on admission in patients with isolated traumatic brain injury: contemporary examination of the incidence and outcomes using a national registry

ABSTRACT Purpose This study was primarily aimed at establishing the incidence and impact of hypotension in patients with blunt traumatic brain injury based on National Trauma Registry Database. Methods A retrospective cohort study using the National Trauma Registry was conducted. Patients with TBI following blunt mechanisms of injury were examined, comparing those with and without hypotension (SBP < 90 mm Hg) on arrival. Results During the period from 1998 to 2017, the registry included 437.354 blunt trauma patients. Of them, 7818 patients were hemodynamically unstable (SBP < 90 mm Hg) on admission. 513 met the inclusion criteria. Significant percentages of patients with high grade injures (ISS≥16) and low admission’s GCS 3-12 (46% vs 16.4%), were found in the group of hypotensive TBI patients (p<0.0001). 323 (62.9%) patients had head AIS score 3-4 and only 190 (37.1%) patients AIS 5-6 (p<0.0001). Mortality in the hypotensive TBI group was 32.3%, whereas 6.1% patients died in the TBI hemodynamically stable group (p<0.0001) Conclusion TBI patients presenting with hypotension represent an appreciable portion blunt trauma patients. Prompt brain CT, expedient efforts at optimal resuscitation and possibly early inotropic and vasopressors agents use may have an impact on final outcome in these patients.

Dendritic arbor complexity and spine density changes after repetitive mild traumatic brain injury and neuroprotective treatments

Traumatic brain injury has been described as the signature affliction of recent military conflicts and repetitive TBIs, particularly associated with military and athletic activities, typically result in more severe clinical effects. The majority of TBIs are mild, but they can result in long term cognitive deficits for which there is no effective treatment. One of the most significant deficits observed in TBI patients is memory loss, which suggests that TBI can induce pathological changes within the hippocampus. tert-butylhydroquinone (tBHQ) and pioglitazone activate the Nrf2 and PPAR-γ transcription factors, respectively, and both have been shown to be neuroprotective in model systems. We examined the morphological changes within the hippocampus following repetitive mild TBI and simultaneous treatment with both factors. We utilized a closed head injury mouse model with five injuries over 5 weeks. Our results showed marked morphological changes among the dendrites and dendritic spines of the neurons of the dentate gyrus of the hippocampus. We observed decreases in overall dendritic length, as well as in the quantity and density of dendritic spines. Our treatment partially ameliorated these effects, suggesting that the Nrf2 and PPAR-γ transcription factors may be important targets for future drug development in the treatment of TBI in humans.

Comparison of Mean Glasgow Outcome Score in Patients with Traumatic Brain Injury after Magnesium Sulphate Therapy and Placebo. A Prospective Study of Shaikh Zayed Hospital Lahore

Objective: We evaluated the effectiveness of magnesium sulphate treatment for the management and outcome of TBI.&#x0D; Material and Methods: The prospective cases (n = 112) of TBI were included from Department of Neurosurgery, Shaikh Zayed Hospital, Lahore. Patients were split into two groups. Magnesium sulphate treatment group (n = 56) and placebo group (n = 56). Detailed history of patients was taken along with comprehensive examinations with CT scans.56 TBI patients were given standard treatment plus magnesium sulphate and remaining 56 patients received just standard treatment.&#x0D; Results: Mean age of the magnesium supplement therapy group was 36.83 ± 13.45 years while in the placebo group was 33.64 ± 12.88 years). Majority 28 (67.9%) were male in the magnesium sulphate group while 37 (66.1%) were in the placebo group. Mean duration passed between hospital presentation and traumatic brain injury was 4.98 ± 2.32 hours in the magnesium sulphate group while it was 5.05 ± 2.48 in the placebo group. Mean Glasgow outcome score was 3.57 ± 1.33 in the magnesium sulphate group while 2.78 ± 1.23 in the placebo group and this difference was statistically significant.&#x0D; Conclusion: There is significant improvement in GOS after magnesium sulphate therapy in patients with traumatic brain injury versus placebo group as noted in the results.

Effect of Multidimensional Exercise Program for Improving Balance in Traumatic Brain Injury Patients

Background- Balance disorder is a common problem in post-TBI patients. In many research’s done before treatment is given mainly on motor component to improve balance in TBI patients. In this study we are going to give multidimensional protocol - sensory stimulations along with motor components. Balance is a main component of a patient for his mobility, many therapist concentrate on balance in chronic stage of TBI patients, in this study we are going to give treatment in acute stage of TBI patients which will help them to recover fast. There is lack of research’s done on acute post TBI patients with multidimensional exercise program for balance disorder. Indeed this made us to study the effect of multidimensional exercise program on balance disorder in TBI patients. Objectives- To find out the effectiveness of multidimensional exercise program for improving balance control in mild TBI patients. To find out the effectiveness of multidimensional exercise program for improving balance control in moderate TBI patients. To find out the effectiveness of multidimensional exercise program for improving balance control in severe TBI patient. METHOD- In this study total 20 candidates were taken having impaired balance secondary to TBI from hospitals in karad. Their balance were assessed by berg balance scale and community balance and mobility scale. They were divided into mild, moderate and severe TBI. A multidimensional exercise protocol of 6 week was given for improving balance and their balance was checked at 2nd, 4th, and 6th week by same BBS and CBMS score. Later evaluation and interpretation of data was done. Result- The 20.8% improvement is seen in pre and post treatment BBS score and 8.82% improvement is seen in pre and post treatment CBMS score in post TBI patients with balance impairment. Conclusion- On the basis of result it can be concluded that multidimensional exercise program is effective for improving balance in TBI patients.

Lobectomy in traumatic brain injury patients with intracerebral hemorrhage and delayed contusion

:Background:TBI, standing for Traumatic Brain Injury, is a leading cause of death worldwide; nonetheless, data on its management has hitherto been sparse. In view of the fact that brain lobectomy is a contentious issue in the management of TBI, we set out the current study to assess the mortality rate and outcomes of TBI with delayed contusion or Intracerebral Hemorrhage (ICH) undergoing lobectomy.Methods:We evaluated 135 TBI patients with delayed contusion or ICH undergoing brain lobectomy from 2001 to 2013. Withal, the mortality and Glasgow Outcome Scale (GOS) and Glasgow Comma Scale (GCS) rates were assessed in these patients and the association in between was sought.Results:The TBI patients undergoing brain lobectomy (77% male versus 23 % female) had a mean age of 43.4±20.3 years and experienced a survival rate of 62.2% (71% in females versus 60% in males). Favorable GOS was observed in 53% of male patients, compared with 27% in the females. Age was demonstrated to significantly affect the mortality rate (p=0.0001). Initial GCS score was associated with GOS as 79.1% of the survived patients with a GCS of higher than 9 on admission were discharged with favorable GOS. Conclusions:The evidence from the present study indicates that lobectomy can be an acceptable surgical procedure in management of TBI patients with delayed contusion or ICH.
