The Relationship

While electroencephalogram (EEG) burst-suppression is often induced therapeutically using sedatives in the intensive care unit (ICU), there is hitherto no evidence with respect to its association to outcome in moderate-to-severe neurological patients. We examined the relationship between sedation-induced burst-suppression (SIBS) and outcome at hospital discharge and at 6-month follow up in patients surviving moderate-to-severe traumatic brain injury (TBI). For each of 32 patients recovering from coma after moderate-to-severe TBI, we measured the EEG burst suppression ratio (BSR) during periods of low responsiveness as assessed with the Glasgow Coma Scale (GCS). The maximum BSR was then used to predict the Glasgow Outcome Scale extended (GOSe) at discharge and at 6 months post-injury. A multi-model inference approach was used to assess the combination of predictors that best fit the outcome data. We found that BSR was positively associated with outcomes at 6 months (P = 0.022) but did not predict outcomes at discharge. A mediation analysis found no evidence that BSR mediates the effects of barbiturates or propofol on outcomes. Our results provide initial observational evidence that burst suppression may be neuroprotective in acute patients with TBI etiologies. SIBS may thus be useful in the ICU as a prognostic biomarker.

Introduction: Traumatic brain injury (TBI) is a major medical and socioeconomic problem. Patients with severe TBI shows physical and functional improvement but remain with cognitive and psycho-social problem throughout recovery. Despite all the issues, the impact of TBI on long-term survivors in Malaysia is unknown. The aim of this study is to measure the functional level of ICU survivors with severe TBI within 6 months post injury. Materials and method: A cohort study was employed for this study. 33 participants from Hospital Tengku Ampuan Afzan (HTAA) Kuantan, Pahang and Hospital Sultanah Nur Zahirah (HSNZ) Kuala Terengganu with severe TBI were included in this study. The functional assessment of Glasgow Outcome Scale Extended (GOSE) was measured in all samples within in a 6 month period. Results: The participants mean age was 31.79 with ranged from 16 to 73 years old. The result of this study showed that within 3 months after discharged from the hospital, all the participants still had poor recovery n=33 (100.0%). Meanwhile, at 6 months after discharge from the hospital, n= 16 (48.5%) participants were scored good recovery. In this case, the SOFA and SAPS II score contributed significantly to the prediction (SOFA score p=0.045, SAPS II score p= 0.028) of functional outcome. Conclusion: The functional outcome of severe TBI improved in six months post injury. The SOFA score and SAPS II score become significant predictors for functional outcome in this study. However, there were some limitations to this study, which are small sample size and short follow-up duration. This study emphasized the importance of SOFA and SAPS II score in predicting functional outcome; thus early care plan should be done if severe TBI have higher SOFA or SAPS II score.

Introduction: Serum neurofilament light (NfL) is an emerging biomarker of traumatic brain injury (TBI). However, the effect of peripheral injuries such as long bone fracture and skeletal muscle injury on serum NfL levels is unknown. Therefore, the aim of this study was to determine whether serum NfL levels can be used as a biomarker of TBI in the presence of concomitant peripheral injuries. Methods: Rats were randomly assigned to one of four injury groups: polytrauma (muscle crush + fracture + TBI; n = 11); peripheral injuries (muscle crush + fracture + sham-TBI; n = 12); TBI-only (sham-muscle crush + sham-fracture + TBI; n = 13); and triple-sham (n = 7). At 2-days post-injury, serum levels of NfL were quantified using a Simoa HD-X Analyzer. Results: Compared to triple-sham rats, serum NfL concentrations were higher in rats with peripheral injuries-only, TBI-only, and polytrauma. When compared to peripheral injury-only rats, serum NfL levels were higher in TBI-only and polytrauma rats. No differences were found between TBI-only and polytrauma rats. Conclusion: Serum NfL levels did not differ between TBI-only and polytrauma rats, indicating that significant peripheral injuries did not affect the sensitivity and specificity of serum NfL as a biomarker of moderate TBI. However, the finding of elevated serum NfL levels in rats with peripheral injuries in the absence of a TBI suggests that the presence of such injuries may limit the utility of NfL as a biomarker of less severe TBI (eg, concussion).

Objective:Our study addressed aims: (1) test the hypothesis that moderate-severe TBI in pediatric patients is associated with widespread white matter (WM) disruption; (2) test the hypothesis that age and sex impact WM organization after injury; and (3) examine associations between WM organization and neurobehavioral outcomes.Methods:Data from ten previously enrolled, existing cohorts recruited from local hospitals and clinics were shared with the ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) Pediatric msTBI working group. We conducted a coordinated analysis of diffusion MRI (dMRI) data using the ENIGMA dMRI processing pipeline.Results:Five hundred and seven children and adolescents (244 with complicated mild to severe TBI [msTBI] and 263 controls) were included. Patients were clustered into three post-injury intervals: acute/subacute - <2 months, post-acute - 2-6 months, chronic - 6+ months. Outcomes were dMRI metrics and post-injury behavioral problems as indexed by the Child Behavior Checklist (CBCL). Our analyses revealed altered WM diffusion metrics across multiple tracts and all post-injury intervals (effect sizes ranging between d=-0.5 to -1.3). Injury severity is a significant contributor to the extent of WM alterations but explained less variance in dMRI measures with increasing time post-injury. We observed a sex-by-group interaction: females with TBI had significantly lower fractional anisotropy in the uncinate fasciculus than controls (𝞫=0.043), which coincided with more parent-reported behavioral problems (𝞫=-0.0027).Conclusions:WM disruption after msTBI is widespread, persistent, and influenced by demographic and clinical variables. Future work will test techniques for harmonizing neurocognitive data, enabling more advanced analyses to identify symptom clusters and clinically-meaningful patient subtypes.

Abstract Objective Recovery following traumatic brain injury (TBI) is complex. Often following mild TBI, recovery occurs within days or weeks, though this is not always the case. Following more severe TBI, some recover quickly, while many never fully recover. This study examines acute predictors of chronic neurobehavioral symptoms in U.S. military service members (Age: M = 33.9 years, SD = 10.2) without injury (n = 86), or with history of uncomplicated mild traumatic brain injury (TBI; n = 56), complicated mild, moderate, or severe TBI (mod-sev TBI; n = 43), or bodily injury (n = 25). Method Participants completed the Neurobehavioral Symptom Inventory (NSI), Posttraumatic Stress Disorder Checklist, Alcohol Use Disorder Checklist, Combat Exposure Scale, and TBI Quality of Life and passed symptom validity tests at 0–8 months and ≥ 2 years post-injury. Forward stepwise logistic regression included 26 potential predictors (demographics, injury characteristics, military characteristics, and self-report measures at baseline) of International Statistical Classification of Diseases and Related Health Problems-10 Postconcussional Syndrome (PCSy) at follow-up. Results Cognitive Concerns (Exp(B) = .896, p = .001), Sleep (Exp(B) = 1.874, p &lt; .001), Somatosensory Symptoms (Exp(B) = 1.194, p = .012), and mod-sev TBI (Exp(B) = 2.959, p = .045) significantly predicted follow-up PCSy. When baseline NSI symptoms were removed from the model, Cognitive Concerns (Exp(B) = .902, p &lt; .001), Post-traumatic stress (Exp(B) = 1.173, p = .001), and Resilience (Exp(B) = .950, p &lt; .031) significantly predicted PCSy. For all included measures in both models, higher symptoms at baseline predicted increased likelihood of follow-up PCSy. Both models correctly classified 81.3% of participants. Conclusion Findings suggest patients reporting psychological distress and cognitive concerns acutely should be targeted for treatment to mitigate prolonged neurobehavioral symptoms.

The Relationship

Although recent evidence suggests a beneficial effect of alcohol for patients with traumatic brain injury (TBI), the level of alcohol that confers the protective effect is unknown. Our objective was to investigate the relationship between admission blood alcohol concentration (BAC) and outcomes in patients with isolated moderate to severe TBI. From 2005 to 2009, the Los Angeles County Trauma Database was queried for all patients ≥14 years of age with isolated moderate to severe TBI and admission serum alcohol levels. Patients were then stratified into four levels based on admission BAC: None (0 mg/dL), low (0-100 mg/dL), moderate (100-230 mg/dL), and high (≥230 mg/dL). Demographics, patient characteristics, and outcomes were compared across levels. In evaluating 3794 patients, the mortality rate decreased with increasing BAC levels (linear trend P < 0.0001). In determining the relationship between BAC and mortality, multivariable logistic regression analysis demonstrated a high BAC level was significantly protective (adjusted odds ratio 0.55; 95% confidence interval: 0.38-0.8; P = 0.002). In the largest study to date, a high (≥230 mg/dL) admission BAC was independently associated with improved survival in patients with isolated moderate to severe TBI. Additional research is warranted to investigate the potential therapeutic implications.

Background: Previous research addressing cognitive recovery after traumatic brain injury (TBI) in adults has predominately used cross-sectional methods. This systematic review examines longitudinal research into cognitive recovery in the first 2 years following moderate-to-severe TBI in adults and aims to identify apparent methodological issues with the existing literature.Design: Systematic review of the first 2 years post-trauma.Setting: Data were extracted from three electronic databases and manual searches of published articles until October 2012.Participants: Two hundred and forty-two participants with severe TBI and 281 comparison participants were used to calculate effect sizes.Results: Twenty papers met the selection criteria, with effect sizes computed from four studies. Moderate-to-large effect sizes were initially observed between the TBI and comparison groups on most measures (range: d = 0.2–2.8). Recovery continued in all five cognitive domains over the 2 years post-injury.Conclusions: Results demonstrated that cognitive recovery was continuous throughout the first 2 years following moderate-to-severe TBI. Findings also indicated different rates of recovery for the specific cognitive domains, highlighting the heterogeneous nature of cognitive recovery after TBI. The review highlighted several methodological issues within the limited existing literature; recommendations were developed to improve the evidence base.

AbstractBehavioral dysregulation is a common and detrimental consequence of traumatic brain injury (TBI) in children that contributes to poor academic achievement and deficits in social development. Unfortunately, behavioral dysregulation is difficult to predict from either injury severity or early neuropsychological evaluation. The uncinate fasciculus (UF) connects orbitofrontal and anterior temporal lobes, which are commonly implicated in emotional and behavioral regulation. Using probabilistic diffusion tensor tractography (DTT), we examined the relationship between the integrity of the UF 3 months post-injury and ratings of executive functions 12 months post-injury in children with moderate to severe TBI and a comparison group with orthopedic injuries. As expected, fractional anisotropy of the UF was lower in the TBI group relative to the orthopedic injury group. DTT metrics from the UF served as a biomarker and predicted ratings of emotional and behavior regulation, but not metacognition. In contrast, the Glasgow Coma Scale score was not related to either UF integrity or to executive function outcomes. Neuroanatomical biomarkers like the uncinate fasciculus may allow for early identification of behavioral problems and allow for investigation into the relationship of frontotemporal networks to brain-behavior relationships.

Objectives Childhood traumatic brain injury (TBI) is a public health issue. Our objectives were to determine the prevalence of permanent pituitary hormone deficiency and to detect the emergence of other pituitary dysfunctions or central precocious puberty several years after severe TBI. Design Follow-up at least 5 years post severe TBI of a prospective longitudinal study. Patients Overall, 66/87 children, who had endocrine evaluation 1 year post severe TBI, were included (24 with pituitary dysfunction 1 year post TBI). Main outcome measures In all children, the pituitary hormones basal levels were assessed at least 5 years post TBI. Growth hormone (GH) stimulation tests were performed 3–4 years post TBI in children with GH deficiency (GHD) 1 year post TBI and in all children with low height velocity (<−1 DS) or low IGF-1 (<−2 DS). Central precocious puberty (CPP) was confirmed by GnRH stimulation test. Results Overall, 61/66 children were followed up 7 (5–10) years post TBI (median; (range)); 17/61 children had GHD 1 year post TBI, and GHD was confirmed in 5/17 patients. For one boy, with normal pituitary function 1 year post TBI, GHD was diagnosed 6.5 years post TBI. 4/61 patients developed CPP, 5.7 (2.4–6.1) years post-TBI. Having a pituitary dysfunction 1 year post TBI was significantly associated with pituitary dysfunction or CPP more than 5 years post TBI. Conclusion Severe TBI in childhood can lead to permanent pituitary dysfunction; GHD and CPP may appear after many years. We recommend systematic hormonal assessment in children 1 year after severe TBI and a prolonged monitoring of growth and pubertal maturation. Recommendations should be elaborated for the families and treating physicians.

Abstract Background: Tracheostomy is very common in patients with severe traumatic brain injury (TBI), and long-term nursing care are needed for those patients. We aimed to evaluate the effects of hospital-community-home (HCH) nursing in those patients. Methods: Tracheostomy patients with severe TBI needing long-term care were included. All patients underwent two months long follow-up. Glasgow coma score (GCS), Karnofsky, Self-Anxiety Scale (SAS) (SAS) and Barthel assessment at the discharge and two months after discharge were evaluated. The tracheostomy related complications were recorded and compared.Results: A total of 60 patients were included. There weren’t significant differences between two groups in the GCS, Karnofsky, SAS and Barthel index at discharge((all p>0.05), the GCS, Karnofsky and Barthel index was all significantly increased after two months follow-up for two groups (all p<0.05), and the GCS, Karnofsky and Barthel index at two months follow-up in HCH group was significantly higher than that of control group(all p<0.05), but the SAS at two months follow-up in HCH group was significantly less than that of control group(p=0.009). The incidence of block of artificial tracheal cannula and readmission in HCH group were significant less than that of control group (all p<0.05).Conclusion: HCH nursing care is feasible in tracheostomy patients with severe TBI, future studies are needed to further evaluate the role of HCH nursing care.

OBJECTIVETraumatic brain injury (TBI) is a significant cause of morbidity and mortality worldwide. Clinical outcomes in TBI are determined by the severity of injury, which is dependent on the primary and secondary brain injury processes. Whereas primary brain injury lesions are related to the site of impact, secondary brain injury results from physiological changes caused by oxidative stress and inflammatory responses that occur after the primary insult. The aim of this study was to identify important clinical and biomarker profiles that were predictive of recovery after moderate to severe TBI. A good functional outcome was defined as a Glasgow Outcome Scale (GOS) score of ≥ 4.METHODSThis was a prospective study of patients with moderate to severe TBI managed at the Nelson Mandela Academic Hospital during the period between March 2014 and March 2016. Following admission and initial management, the patient demographic data (sex, age) and admission Glasgow Coma Scale score were recorded. Oxidative stress and inflammatory biomarkers in blood and CSF were sampled on days 1–7. On day 14, only blood was sampled for the same biomarkers. The primary outcome was the GOS score—due to its simplicity, the GOS was used to assess clinical outcomes at day 90. Because of difficulty in performing regular follow-up due to the vastness of the region, difficult terrain, and long travel distances, a 3-month follow-up period was used to avoid default.RESULTSSixty-four patients with Glasgow Coma Scale scores of ≤ 12 were seen and managed. Among the 56 patients who survived, 42 showed significant recovery (GOS score ≥ 4) at 3 months. Important predictors of recovery included antioxidant activity in the CSF (superoxide dismutase and total antioxidant capacity).CONCLUSIONSRecovery after TBI was dependent on the resolution of oxidative stress imbalance.
