Prognostic Value of Initial Diagnostic Imaging Findings for Patient Outcomes in Adult Patients with Traumatic Brain Injury: A Systematic Review and Meta-Analysis. Tomography 2023; 9:509-528. [PMID: 36961001 PMCID: PMC10037627 DOI: 10.3390/tomography9020042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 02/15/2023] [Accepted: 02/16/2023] [Indexed: 03/02/2023] Open
Abstract
INTRODUCTION Termed the "silent epidemic," traumatic brain injury (TBI) is one of the greatest global contributors not only to post-traumatic death but also to post-traumatic long-term disability. This systematic review and meta-analysis aims to specifically evaluate the prognostic value of features on initial imaging completed within 24 h of arrival in adult patients with TBI. METHOD The authors followed the PRISMA 2020 checklist for systematic review and meta-analysis design and reporting. Comprehensive searches of the Medline and Embase databases were carried out. Two independent readers extracted the following demographic, clinical and imaging information using a predetermined data abstraction form. Statistics were performed using Revman 5.4.1 and R version 4.2.0. For pooled data in meta-analysis, forest plots for sensitivity and specificity were created to calculate the diagnostic odds ratio (DOR). Summary receiver operating characteristic (SROC) curves were generated using a bivariate model, and diagnostic accuracy was determined using pooled sensitivity and specificity as well as the area under the receiver operator characteristic curve (AUC). RESULTS There were 10,733 patients over the 19 studies. Overall, most of the studies included had high levels of bias in multiple, particularly when it came to selection bias in patient sampling, bias in controlling for confounders, and reporting bias, such as in reporting missing data. Only subdural hematoma (SDH) and mortality in all TBI patients had both an AUC with 95% CI not crossing 0.5 and a DOR with 95% CI not crossing 1, at 0.593 (95% CI: 0.556-0.725) and 2.755 (95% CI: 1.474-5.148), respectively. CONCLUSION In meta-analysis, only SDH with mortality in all TBI patients had a moderate but significant association. Given the small number of studies, additional research focused on initial imaging, particularly for imaging modalities other than NECT, is required in order to confirm the findings of our meta-analysis and to further evaluate the association of imaging findings and outcome.

Abstract
OBJECTIVE By extracting clinical and computed tomography imaging data of patients with acute subdural hematoma (ASDH), factors that were significantly associated with poor prognosis were screened and a nomogram model was established and validated. METHODS All patients with ASDH who underwent subdural hematoma removal and decompressive craniectomy from January 2014 to March 2018 in Qinghai Provincial People's Hospital were continuously collected. Finally, 124 patients were included in the study. According to the Glasgow Outcome Scale at 3 months after operation, patients were divided into a good prognosis group and a poor prognosis group. RESULTS Univariate and binary logistic regression analysis were performed to screen out independent predictors that were significantly associated with poor prognosis of ASDH. On the basis of these factors, a nomogram model was established. CONCLUSIONS The nomogram model had high accuracy for predicting poor prognosis in patients with ASDH, and it was easy to promote. In the future, large sample and multicenter prospective studies are necessary to complement and identify the results.

Abstract
OBJECTIVE Gray matter (GM) and white matter (WM) are vulnerable to ischemic-edematous insults after traumatic brain injury (TBI). The extent of secondary insult after brain injury is quantifiable using quantitative CT analysis. One conventional quantitative CT measure, the gray-white matter ratio (GWR), and a more recently proposed densitometric analysis are used to assess the extent of these insults. However, the prognostic capacity of the GWR in patients with TBI has not yet been validated. This study aims to test the prognostic value of the GWR and evaluate the alternative parameters derived from the densitometric analysis acquired during the acute phase of TBI. In addition, the prognostic ability of the conventional TBI prognostic models (i.e., IMPACT [International Mission for Prognosis and Analysis of Clinical Trials in TBI] and CRASH [Corticosteroid Randomisation After Significant Head Injury] models) were compared to that of the quantitative CT measures. METHODS Three hundred patients with TBI of varying ages (92 pediatric, 94 adult, and 114 geriatric patients) and admitted between 2008 and 2013 were included in this retrospective cohort study. The normality of the density of the deep GM and whole WM was evaluated as the proportion of CT pixels with Hounsfield unit values of 31-35 for GM and 26-30 for WM on CT images of the entire supratentorial brain. The outcome was evaluated using the Glasgow Outcome Scale (GOS) at discharge (GOS score ≤ 3, n = 100). RESULTS Lower proportions of normal densities in the deep GM and whole WM indicated worse outcomes. The proportion of normal WM exhibited a significant prognostic capacity (area under the curve [AUC] = 0.844). The association between the outcome and the normality of the WM density was significant in adult (AUC = 0.792), pediatric (AUC = 0.814), and geriatric (AUC = 0.885) patients. In pediatric patients, the normality of the overall density and the density of the GM were indicative of the outcome (AUC = 0.751). The average GWR was not associated with the outcome (AUC = 0.511). IMPACT and CRASH models showed adequate and reliable performance in the pediatric and geriatric groups but not in the adult group. The highest overall predictive performance was achieved by the densitometry-augmented IMPACT model (AUC = 0.881). CONCLUSIONS Both deep GM and WM are susceptible to ischemic-edematous insults during the early phase of TBI. The extent of the secondary injury was better evaluated by analyzing the normality of the deep GM and WM rather than by calculating the GWR.

Abstract
Subdural hemorrhage is commonly associated with mechanical brain injury and has a correspondingly high mortality rate. Subdural hematomas may immediately provoke symptoms or may be initially asymptomatic, with further symptoms evolving rapidly and fatally.The data regarding forensic autopsy of victims were obtained from The State Forensic Medicine Service of Lithuania between the years 2013 and 2016. A retrospective study was performed including 110 patients, whose cause of death was subdural hemorrhage. 95% confidence intervals were calculated.It was calculated, that in cases of sudden death, after subdural hemorrhage was diagnosed, a higher concentration of ethyl alcohol in blood (mean 2.22 ± 1.3%) demanded a smaller amount of blood under the dura matter (mean 81.6 ± 60.5 g) in order for the patient to die. It was also noted that hospitalized patients with subdural hemorrhage had a smaller concentration of blood ethyl alcohol (mean 1.33 ± 1%) and a larger amount of blood under the dura (mean 135.6 ± 82.9 g).Due to the toxic effect of ethyl alcohol, even a small amount (81.6 ± 60.5 g) of blood under the dura matter can determine a sudden death.

Dunham CM, Malik RJ, Huang GS, Kohli CM, Brocker BP, Ugokwe KT. Hypertonic saline administration and complex traumatic brain injury outcomes: a retrospective study. INTERNATIONAL JOURNAL OF BURNS AND TRAUMA 2018; 8:40-53. [PMID: 30042863 PMCID: PMC6055080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/28/2018] [Accepted: 06/12/2018] [Indexed: 06/08/2023]
Abstract
Although hypertonic saline (HTS) decreases intracranial pressure (ICP) with traumatic brain injury (TBI), its effects on survival and post-discharge neurologic function are less certain. We assessed the impact of HTS administration on TBI outcomes and hypothesized that favorable outcomes would be associated with larger amounts of 3% saline. This is a retrospective study of consecutive-patients with the following criteria: blunt trauma, age 18-70 years, intracranial hemorrhage, Glasgow Coma Scale score (GCS) 3-12, and mechanical ventilation ≥ 5 days. The need for craniotomy or craniectomy denoted surgical decompression patients. Amounts of HTS were during the first-5 trauma center days. Traits for the 112 patients during 2012-2016 were as follows: GCS, 6.8 ± 3.2; subdural hematoma, 71.4%; cerebral contusion, 31.3%, ICP device, 47.3%; surgical decompression, 51.8%; ventilator days, 14.8 ± 6.7; trauma center mortality, 13.4%; and no commands at 3 months 35.5%. In surgically decompressed patients, trauma center mortality was greater with ≤ 8.0 mEq/kg sodium (38.9%) than with > 8.0 mEq/kg (7.5%; P = 0.0037). In surgically decompressed patients, following commands at 3 months was greater with ≥ 1400 mEq sodium (76.9%) than with < 1400 mEq (50.0%; P = 0.0489). For trauma center surviving non-decompression patients with no ICP device, those following commands at 3 months received more sodium (513 ± 784 mEq) than individuals not following commands (82 ± 144 mEq; P = 0.0142). For patients with a GCS 5-8, following commands at 3 months was greater with ≥ 1350 mEq sodium (92.3%) than with < 1350 mEq (60.0%; P = 0.0214). In patients with subdural hematoma or cerebral contusion, following commands at 3 months was greater with ≥ 1400 mEq sodium (84.2%) than with < 1400 mEq (61.8%; P = 0.0333). Patients with ICP > 20 mmHg for ≤ 10 hours (mean hours 2.0) received more sodium (16.5 ± 11.5 mEq/kg) when compared to ICP elevation for ≥ 11 hours (mean hours 34) (9.4 ± 6.3 mEq/kg; P = 0.0139). These observations demonstrate that hypertonic saline administration in patients with complex traumatic brain injury is associated with 1) mitigation of intracranial hypertension, 2) trauma center survival, and 3) following commands at 3 months post-injury.

Abstract
OBJECTIVE To evaluate relationship between gray-white matter ratio (GWR) on computed tomography and prognosis in patients with extra-axial hematoma. METHODS Patients with extra-axial hematoma who had undergone surgical treatment at Qinghai Provincial People's Hospital from September 2016 to December 2017 were included. GWR values were calculated by measuring values of gray matter and white matter in Hounsfield units in noninjury sites of basal ganglia. According to Glasgow Outcome Scale score at 3 months after operation, patients were divided into good prognosis (Glasgow Outcome Scale score 4-5) and poor prognosis (Glasgow Outcome Scale score 1-3) groups. RESULTS Of 103 patients who met inclusion criteria and were analyzed, 24 had with a poor outcome, including 5 deaths, and 79 patients had a good outcome. There were significant differences between the 2 groups in terms of age, type of hematoma, admission Glasgow Coma Scale score, and presence of hernia (all P < 0.05). Postoperative HU values of posterior capsule, postoperative GWR values, and difference between preoperative and postoperative GWR values had statistical significance (all P < 0.05). Receiver operating characteristic curve showed that difference between preoperative and postoperative GWR values was the best predictor of poor outcome. CONCLUSIONS The difference between preoperative or postoperative GWR values has a higher sensitivity and greater area under the curve to predict patient outcome. Measuring the difference between preoperative and postoperative GWR values may be useful as an objective early predictor of outcome in patients with extra-axial hematoma. Larger samples and multicenter prospective studies are still required.
