Endovascular treatment of ruptured basilar artery trunk aneurysms: complications and long-term outcomes

ObjectTreatment of ruptured basilar artery trunk (BAT) aneurysms is challenging, and is associated with high complication and mortality rates. Herein, we analyzed the complications, long-term outcomes, and outcome predictors of endovascular treatment for ruptured BAT aneurysms. MethodsBetween January 2011 and July 2023, 36 patients with 36 ruptured BAT aneurysms underwent endovascular treatment at our institution. The postprocedural complications and clinical and angiographic outcomes were subsequently reviewed, and the risk factors for postprocedural complications were evaluated. ResultsAll 36 aneurysms in 36 patients were treated successfully. The median clinical follow-up time was 47.0 (IQR: 10.5, 84.5) months. Overall, complications occurred in 10 (27.8%) patients, including 3 (8.3%) deaths. Ischemic events occurred in seven (19.4%) patients, while three (8.3%) patients had shunt-dependent hydrocephalus, of whom one (2.8%) patient had both shunt-dependent hydrocephalus and ischemic events. The cumulative survival rates at 3 and 5 years were 94.1% and 87.8%, respectively. The cumulative 3- and 5-year complication-free survival rates were 75.0% and 70.0%, respectively. Multivariate Cox regression analysis revealed that diabetes mellitus (HR:8.76, 95%CI:2.35-32.69, p=0.001), and Glasgow coma scale score ≤ 12 before the procedure (HR:5.04, 95%CI:1.40-18.12, p=0.013) were associated with overall postprocedural complications. The complete aneurysm occlusion rate was 61.5% at a median angiography follow-up time of 6.0 (IQR: 5.0, 6.0) months. ConclusionsEndovascular treatment is a safe and feasible option for treating ruptured BAT aneurysms. The rate of favorable outcomes at the final follow-up was satisfactory. However, postprocedural complications, particularly ischemic events, should be carefully considered.

Surgical Results with Low-Grade Arteriovenous Malformations : A Single Center 14-Year Experience.

Advancements in AVM surgical techniques for cerebral arteriovenous malformation (AVM) underscore its efficacy. Our research aims to showcase the positive outcomes of treating low-grade AVMs surgically, focusing on safety and effectiveness. We retrospectively reviewed 55 patients (36 males and 19 females; average age 37.4 years) with Spetzler-Martin (S-M) grade 1 and 2 AVMs who underwent surgical resection between January 2009 and December 2022. In our study, 55 patients with S-M grade 1 and 2 AVMs underwent surgical resection, evenly divided between grades 1 (50.9%) and 2 (49.1%). Intracranial hemorrhage was the primary symptom in 74.5% of cases. Pre-operative Glasgow coma scale (GCS) scores revealed 69.1% of patients scored above 13, with 18% below 8. Successful resection was achieved in 87.3%. Postoperatively, 95.5% of ruptured and 90.9% of unruptured AVM patients showed lower or same modified Rankin scale scores. Poorer outcomes were significantly linked to lower GCS scores and intranidal/flow-related aneurysms through multivariate logistic regression. Postoperative seizures noted in nine patients, were exclusive to the ruptured AVM group. Our findings indicate surgical resection as a beneficial treatment for low-grade AVMs, yielding high cure rates and positive functional outcomes in both ruptured and unruptured cases. Preoperative GCS scores and the presence of associated aneurysms are predictive of postoperative functional status. Additionally, managing postoperative seizures effectively is key to enhancing prognosis.

Epidemiological characteristics of ventilator-associated pneumonia in neurosurgery: A 10-year surveillance study in a Chinese tertiary hospital

BackgroundVentilator-associated pneumonia (VAP) is a significant and common health concern. The epidemiological landscape of VAP is poorly understood in neurosurgery patients. This study aimed to explore the epidemiology of VAP in this population and devise targeted surveillance, treatment, and control efforts. MethodsA 10-year retrospective study spanning 2011 to 2020 was performed in a large Chinese tertiary hospital. Surveillance data was collected from neurosurgical patients and analyzed to map the demographic and clinical characteristics of VAP and describe the distribution and antimicrobial resistance profile of leading pathogens. Risk factors associated with the presence of VAP were explored using boosted regression tree (BRT) models. ResultsThree hundred ten VAP patients were identified. The 10-year incidence of VAP was 16.21 per 1000 ventilation days. All-cause mortality was 6.1%. The prevalence of gram-negative bacteria, fungi, and gram-positive bacteria among the 357 organisms isolated from VAP patients was 86.0%, 7.6%, and 6.4%, respectively; most were multidrug-resistant organisms. Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa were the most common pathogens. The prevalence of carbapenem-resistant A. baumannii, P. aeruginosa, and K. pneumoniae was high and increased over time in the study period. The BRT models revealed that VAP was associated with number of days of ventilator use (relative contribution, 47.84 ± 7.25), Glasgow Coma Scale score (relative contribution, 24.72 ± 5.67), and tracheotomy (relative contribution, 21.50 ± 2.69). ConclusionsOur findings provide a better understanding of the epidemiology of VAP and its risk factors in neurosurgery patients.

A two-center prospective cohort study of serum RIP-3 as a potential biomarker in relation to severity and prognosis after severe traumatic brain injury.

Receptor-interacting protein kinase-3 (RIP-3) is a key component for inducing necroptosis following acute brain injury. Purpose of this study is to unveil whether serum RIP-3 levels are related to severity and clinical outcomes after human severe traumatic brain injury (sTBI). In this two-center prospective cohort study, serum RIP-3 levels were detected in 127 healthy controls coupled with 127 sTBI patients. The prognostic indicators encompassed posttraumatic 180-day mortality, overall survival and poor prognosis (defined as extended Glasgow outcome scale scores of 1-4). The prognosis associations were verified via multivariate analysis. There was a significant incremental serum RIP-3 levels in patients with sTBI, relative to the controls. RIP-3 levels of patients were independently correlated with Rotterdam Computed Tomography (CT) scores and Glasgow coma scale (GCS) scores, as well as were independently predictive of mortality, overall survival and poor prognosis. Mortality and poor prognosis were effectively predicted by serum RIP-3 levels under the receiver operating characteristic curve. Linear relationships between RIP-3 levels and their risks were verified. Mortality and poor prognosis models of serum RIP-3 levels combined with GCS and Rotterdam CT scores displayed efficient predictive abilities. The two models were graphically represented, which were of clinical stability and value by employing the calibration and decision curves. Increased serum RIP-3 levels after sTBI are closely linked to heightened trauma severity and poor prognosis, signifying that serum RIP-3 may be an encouraging biomarker for evaluating severity and predicting clinical outcome of sTBI.

The Etiology of Non-traumatic Loss of Consciousness in Patients Admitted to the Emergency Department

Background: Loss of consciousness (LOC) is one of the most common complaints in the emergency department (ED). This disorder can result from a wide range of clinical conditions, such as structural brain damage, infection, shock, respiratory failure, or psychiatric disorders. Objectives: This study was conducted with the aim of investigating the cause and prognosis of patients with non-traumatic LOC referred to two referral hospitals of Mashhad University. Methods: This prospective cohort study was conducted on 1000 patients presenting with complaints of LOC at Ghaem and Imam Reza hospitals in Mashhad in 2020. All patients with a decreased level of consciousness and a Glasgow Coma Scale (GCS) score of less than 14 were included in the investigation. Results: A total of 1037 patients participated in this study, while 37 patients were excluded. Of the participants, 524 (52.4%) were men and 476 (47.6%) were women. The average age was 59.85 ± 16.06 years, ranging from 18 to 95 years. The relatively common causes of LOC included sepsis (38.3%), stroke (9.2%), heart failure (8%), myocardial infarction (7.3%), meningitis (7.2%), hepatic encephalopathy (6.5%), and toxic alcohol ingestion (5.8%). Deceased patients were older, had higher respiratory rates and temperatures, and had lower blood sugar and blood pressure upon admission. A previous history of stroke, hyperlipidemia, hypertension, and diabetes were associated with death. The relationships between different study outcomes were assessed using multivariate binary logistic regression; a two-sided P < 0.05 was considered significant. Conclusions: Patients presenting to the ED with LOC are more likely to die, making LOC a potential prognostic factor for in-hospital death.

Clinical trauma severity of indoor and outdoor injurious falls requiring emergency medical service response

BackgroundInjurious falls represent a significant public health burden. Research and policies have primarily focused on falls occurring indoors despite evidence that outdoor falls account for 47–58% of all falls requiring some medical attention. This study described the clinical trauma severity of indoor versus outdoor injurious falls requiring Emergency Medical Services (EMS) response.MethodsUsing the 2019 National Emergency Medical Services Information System (NEMSIS) dataset, we identified the location of patients injured from falls that required EMS response. We classified injury severity using (1) the Revised Trauma Score for Triage (T-RTS): ≤ 11 indicated the need for transport to a Trauma Center; (2) Glasgow Coma Scale (GCS): ≤ 8 and 9–12 indicated severe and moderate neurologic injury; and (3) patient clinical acuity by EMS: Dead, Critical, Emergent, Low.ResultsOf 1,854,909 encounters for patients with injurious falls, the vast majority occurred indoors (n = 1,596,860) compared to outdoors (n = 152,994). For patients who fell indoors vs outdoors on streets or sidewalks, the proportions were comparable for moderate or severe GCS scores (3.0% vs 3.9%), T-RTS scores indicating need for transport to a Trauma Center (5.2% vs 5.9%) and EMS acuity rated as Emergent or Critical (27.7% vs 27.1%). Injurious falls were more severe among male patients compared to females and males injured by falling on streets or sidewalks had higher percentages for moderate or severe GCS scores (5.2% vs 1.9%) and T-RTS scores indicating the need for transport to a Trauma Center (7.3% vs 3.9%) compared to falling indoors. Young and middle-aged patients who fell on streets or sidewalks had higher proportions for a T-RTS score indicating the need for Trauma Center care compared to those in this subgroup who fell indoors. Yet older patients injured by falling indoors were more likely to have a T-RTS score indicating the need for transport to a Trauma Center than older patients who fell on streets or sidewalks.ConclusionsThere was a similar proportion of patients with severe injurious falls that occurred indoors and outdoors on streets or sidewalks. These findings suggest the need to determine outdoor environmental risks for outdoor falls to support location-specific interventions.

Acute hemorrhagic leukoencephalitis: a case report and systematic review of factors associated with severe disability and death.

Acute hemorrhagic leukoencephalitis (AHLE), a rare form of acute disseminated encephalomyelitis (ADEM), has a generally poor prognosis. However, significant variation is observed, and even complete recovery has been reported. The recent increase in the frequency of AHLE case reports is possibly contributed by the advent of COVID-19 and may have added to the heterogeneity of cases. We report a fatal case of AHLE with a preceding unspecified respiratory infection, then perform a systematic review of AHLE, in an effort to delineate factors that may be associated with an ultimate outcome of severe disability (defined as modified Rankin scale score of 4 or 5) or death. Descriptions of 31 cases of AHLE were found in 21 identified articles, with our case being the 32nd case. The most common antecedent event was an infection (20 patients, 62.5%), with nearly half of these being COVID-19 (9 patients). The majority of patients had a subacute progression (1 to 10days) from onset to clinical nadir. We found that an altered mental status (AMS) and a Glasgow Coma Scale (GCS) score of less than12 were associated with a final outcome of severe disability or death. An abnormal upgoing plantar response was associated with a final outcome of death. COVID-19 and its vaccines were not associated with either outcome. AMS, depressed GCS, and an upgoing plantar response at presentation may be associated with a poor outcome in AHLE. Our findings may serve as a springboard to much-needed research into the stratification of AHLE.

Systematic quantitative evaluation of gene polymorphism and therapeutic effect of xingnaojing injection in patients with brain injury.

The incidence of brain injury is increasing year by year, and it has become one of the major diseases threatening human life in today's society. From the perspective of the causes of brain injury, it is mainly due to falls from high places, traffic accidents, etc. Severe brain injury patients often lose consciousness. In recent years, the emergence of integrated traditional Chinese and Western medicine has provided a new approach and new ideas for the treatment of craniocerebral trauma. The article systematically and scientifically expounded the role of Xingnaojing injection in the treatment of brain injury by comparing the GCS (Glasgow Coma Scale) score, changes in intracranial pressure, the incidence of complications after brain injury, the transformation from moderate brain injury to severe brain injury, and recovery of consciousness. For the problem of gene polymorphism in patients with brain injury, this article discussed the role of APOE2 (Apolipoprotein E2), ε3, ε4 in brain injury. All patients had a clear history of trauma and received strict nervous system examination and CT scanning when they were admitted to the hospital. After craniocerebral trauma surgery or conservative therapy, patients should take a Xingnaojing injection of 30 ml and a 0.9% sodium chloride injection of 250 ml after admission. After the operation, respiratory tract nursing should be strengthened, and patients who cannot eat should be given nasal feeding, acupuncture, and physiotherapy to prevent bedridden complications. The probability of epilepsy after brain injury was 27%. The article would help to evaluate the degree of brain damage and prognosis of patients.

Diagnostic and prognostic utility of plasma thrombospondin-1 levels in traumatic brain injury.

Thrombospondin-1 (TSP-1), a powerful antiangiogenic agent, is increasingly expressed in mice brain tissues after traumatic brain injury (TBI). However, in the peripheral blood of TBI patients, TSP-1 concentrations have not been identified. This study aimed to determine if TSP-1 measured in the plasma of patients relates to TBI diagnosis and injury severity. Plasma TSP-1 levels were assessed in 75 patients with mild to severe TBI and 60 healthy volunteers. Glasgow Coma Scale (GCS) score was recorded to assess traumatic severity. Other relevant clinical characters and laboratory tests were collected to evaluate the diagnostic efficiency of TSP-1. Glasgow outcome scale (GOSE) 3 months after trauma was dichotomized into unfavorable (GOSE1-4) and favorable (GOSE5-8) outcomes. TSP-1 levels were significantly higher in TBI patients than in controls (median 530.4 ng/l, the upper- lower quartiles 373.2-782.1 vs. median 201.5mg/l, the upper - lower quartiles 83.1-351.4, P < 0.001). Plasma TSP-1 was able to differentiate patients with mild, moderate, and severe TBI from healthy controls with Area Under the Receiver-Operating Characteristic Curve (AUROC) of 0.8089, 0.9312, and 0.9189, respectively. TSP-1 levels were closely and negatively correlated with GCS score (r = -0.41). TSP-1 levels > 624.4 ng/ml independently predicted a 3-month unfavorable outcome with an odds ratio value of 9.666 (95% confidence interval (CI),1.393-69.072). TSP-1 levels significantly discriminated 3-month unfavorable outcome with AUROC of 0.7445 (95%CI, 0.6152-0.8739). The results of this study indicate that plasma TSP-1 should be further investigated as a diagnostic and prognostic marker for patients with TBI.

Phenotypes of Patients with Intracerebral Hemorrhage, Complications, and Outcomes.

The objective of this study was to define clinically meaningful phenotypes of intracerebral hemorrhage (ICH) using machine learning. We used patient data from two US medical centers and the Antihypertensive Treatment of Acute Cerebral Hemorrhage-II clinical trial. We used k-prototypes to partition patient admission data. We then used silhouette method calculations and elbow method heuristics to optimize the clusters. Associations between phenotypes, complications (e.g., seizures), and functional outcomes were assessed using the Kruskal-Wallis H-test or χ2 test. There were 916 patients; the mean age was 63.8 ± 14.1 years, and 426 patients were female (46.5%). Three distinct clinical phenotypes emerged: patients with small hematomas, elevated blood pressure, and Glasgow Coma Scale scores > 12 (n = 141, 26.6%); patients with hematoma expansion and elevated international normalized ratio (n = 204, 38.4%); and patients with median hematoma volumes of 24 (interquartile range 8.2-59.5) mL, who were more frequently Black or African American, and who were likely to have intraventricular hemorrhage (n = 186, 35.0%). There were associations between clinical phenotype and seizure (P = 0.024), length of stay (P = 0.001), discharge disposition (P < 0.001), and death or disability (modified Rankin Scale scores 4-6) at 3-months' follow-up (P < 0.001). We reproduced these three clinical phenotypes of ICH in an independent cohort (n = 385) for external validation. Machine learning identified three phenotypes of ICH that are clinically significant, associated with patient complications, and associated with functional outcomes. Cerebellar hematomas are an additional phenotype underrepresented in our data sources.

Comparison and combined use of NEWS2 and GCS scores in predicting mortality in stroke and traumatic brain injury: a multicenter retrospective study.

This study aims to assess the effectiveness of the National Early Warning Score 2 (NEWS2) versus Glasgow Coma Scale (GCS) in predicting hospital mortality among patients with stroke and traumatic brain injury (TBI). This multicenter study was conducted at two anonymized tertiary care hospitals in distinct climatic regions of China, with a combined annual emergency admission exceeding 10,000 patients. The study included 2,276 adult emergency admissions diagnosed with stroke (n = 1,088) or TBI (n = 1,188) from January 2021 to December 2023, excluding those with chronic pulmonary disease, severe cardiac conditions, or a history of brain surgery. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were utilized to analyze the predictive accuracy of NEWS2 and GCS for hospital mortality at 24, 48, and 72 h post-admission and at discharge. Out of 2,276 patients (mean age 61.4, 65.6% male), 1855 survived while 421 succumbed. NEWS2 demonstrated superior predictive accuracy (AUC = 0.962) over GCS (AUC = 0.854) for overall hospital mortality. Specifically, NEWS2 outperformed GCS in predicting mortality at 24 h (0.917 vs. 0.843), 48 h (0.893 vs. 0.803), and 72 h (0.902 vs. 0.763). Notably, despite a higher AUC for NEWS2 at predicting 24-h hospital mortality, the sensitivity and specificity of GCS were considerably lower (12 and 31%, respectively) compared to NEWS2 (sensitivity of 95% and specificity of 81%). Subgroup analysis showed NEWS2 outperforming GCS in predicting in-hospital mortality for TBI and stroke patients. For TBI patients (n = 260), NEWS2 had an AUC of 0.960 (95% CI: 0.948-0.973) vs. GCS's AUC of 0.811 (95% CI: 0.781-0.840). For stroke patients (n = 161), NEWS2 had an AUC of 0.930 (95% CI: 0.908-0.952) vs. GCS's AUC of 0.858 (95% CI, 0.823-0.892). NEWS2 showed greater sensitivity in both groups, highlighting its effectiveness in identifying high-risk neurological patients. NEWS2 scores are more precise and effective in predicting hospital mortality in stroke and TBI patients compared to GCS scores, although slightly less so within the first 24 h. Combining NEWS2 with GCS and clinical findings within the initial 24 h is recommended for a comprehensive prognosis evaluation.

Effectiveness of early rehabilitation interventions in patients with traumatic brain injury using a large database.

Rehabilitation is important for patients with moderate-to-severe traumatic brain injury (TBI). However, the timing of early rehabilitation initiation is ambiguous, and its safety and effectiveness are unknown. To examine the effectiveness and safety of early rehabilitation in patients with moderate-to-severe TBI using propensity score analysis and a large database. Retrospective cohort study. A large medical database (JMDC database) of tertiary care facilities was used to compare outcomes of early and delayed rehabilitation. Patients aged between 20 and 90 years who were diagnosed with TBI were admitted to acute care hospitals. Inclusion criteria were patients undergoing rehabilitation within 7 days of admission with a Glasgow Coma Scale score of 3 to 12 on admission. This study included 3074 patients with moderate-to-severe TBI. Patients were classified into an early rehabilitation group (within 2 days of admission) or a delayed rehabilitation group (3 to 7 days postadmission), depending on when rehabilitation started after TBI. Rehabilitation was defined as any type or intensity of intervention provided by a physical, occupational, and/or speech/language therapist. Interventions were not controlled. The primary outcome was Barthel Index (BI) efficiency (BI gain/length of stay). Secondary outcomes included BI gain (discharge BI - admission BI), incidence of aspiration pneumonia complications during hospitalization, discharge to home, mortality, and length of stay. After applying inverse probability weighting with propensity scores, the total was 6152 patients. 3074 (50.0%) patients received early rehabilitation. The early rehabilitation group showed no difference in inpatient mortality (p = .438), improved BI efficiency (β = 0.86, p < .001), and shorter length of stay (β = -5.00, p = .018). Early rehabilitation in patients with moderate-to-severe TBI is associated with more efficient functional improvement and reduced hospital stays without an increase in inpatient mortality.

MRI and Clinical Variables for Prediction of Outcomes After Pediatric Severe Traumatic Brain Injury

Traumatic brain injury (TBI) is a leading cause of death and disability in children, and predicting functional outcome after TBI is challenging. Magnetic resonance imaging (MRI) is frequently conducted after severe TBI; however, the predictive value of MRI remains uncertain. To identify early MRI measures that predict long-term outcome after severe TBI in children and to assess the added predictive value of MRI measures over well-validated clinical predictors. This preplanned prognostic study used data from the Approaches and Decisions in Acute Pediatric TBI (ADAPT) prospective observational comparative effectiveness study. The ADAPT study enrolled 1000 consecutive children (aged <18 years) with severe TBI between February 1, 2014, and September 30, 2017. Participants had a Glasgow Coma Scale (GCS) score of 8 or less and received intracranial pressure monitoring. Magnetic resonance imaging scans performed as part of standard clinical care within 30 days of injury were collected at 24 participating sites in the US, UK, and Australia. Summary imaging measures were correlated with the Glasgow Outcome Scale-Extended for Pediatrics (GOSE-Peds), and the predictive value of MRI measures was compared with the International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT) core clinical predictors. Data collection, image analysis, and data analyses were completed in July 2023. Pediatric severe TBI with an MRI scan performed as part of clinical care. All measures were selected a priori. Magnetic resonance imaging measures included contusion, ischemia, diffuse axonal injury, intracerebral hemorrhage, and brainstem injury. Clinical predictors included the IMPACT core measures (GCS motor score and pupil reactivity). All models adjusted for age and sex. Outcome measures included the GOSE-Peds score obtained at 3, 6, and 12 months after injury. This study included 233 children with severe TBI who were enrolled at participating sites and had an MRI scan and preselected clinical predictors available. Their median age was 6.9 (IQR, 3.0-13.3) years, and more than half of participants (134 [57.5%]) were male. In a multivariable model including MRI measures and IMPACT core clinical variables, contusion volume (odds ratio [OR], 1.13; 95% CI, 1.02-1.26), brain ischemia (OR, 2.11; 95% CI, 1.58-2.81), brainstem lesions (OR, 5.40; 95% CI, 1.90-15.35), and pupil reactivity were each independently associated with GOSE-Peds score. Adding MRI measures to the IMPACT clinical predictors significantly improved model fit and discrimination between favorable and unfavorable outcomes compared with IMPACT predictors alone (area under the receiver operating characteristic curve, 0.77; 95% CI, 0.72-0.85 vs 0.67; 95% CI, 0.61-0.76 for GOSE-Peds score >3 at 6 months after injury). In this prognostic study of children with severe TBI, the addition of MRI measures significantly improved outcome prediction over well-established and validated clinical predictors. Magnetic resonance imaging should be considered in children with severe TBI to inform prognosis and may also promote stratification of patients in future clinical trials.

Clinical features and prognostic model for viral encephalitis after allogeneic haematopoietic stem cell transplantation.

The objective of this study was to identify independent prognostic factors of viral encephalitis (VE) after allogeneic haematopoietic stem cell transplantation (allo-HSCT) and establish a prognostic model to identify post-transplant VE patients with a greater likelihood of mortality. Among 5380 patients in our centre from 2014 to 2022, 211 patients who developed VE after allo-HSCT were reviewed in this retrospective study. Prognostic factors were selected, and a prognostic model was constructed using Cox regression analysis. The model was subsequently validated and estimated using the area under the receiver operating characteristic curve (AUC), a calibration plot and decision curve analysis (DCA). Glasgow Coma Scale score <9, lesions >3 lobes on magnetic resonance imaging and severe thrombocytopenia were identified as independent prognostic risk factors for VE patients who underwent allo-HSCT. The prognostic model GTM (GTM is an abbreviation for a model composed of three risk factors: GCS score <9, severe thrombocytopenia [platelet count <20 000 per microliter], and lesions >3 lobes on MRI) was established according to the regression coefficients. The validated internal AUC was 0.862 (95% confidence interval [CI], 0.773-0.950), and the external AUC was 0.815 (95% CI, 0.708-0.922), indicating strong discriminatory ability. Furthermore, we constructed calibration plots that demonstrated good consistency between the predicted outcomes and the observed outcomes. DCA exhibited high accuracy in this system, leading to potential benefits for patients.

Elevated cerebrospinal fluid galectin-3 and associated cytokines after severe traumatic brain injury in patients.

This study aimed to investigate the galectin-3 and associated cytokines levels in the cerebrospinal fluid (CSF) of severe traumatic brain injury (sTBI) patients. Temporal CSF expression of galectin-3 and associated cytokines levels in sTBI patients within 1-week post-injury were studied using the multiplex bead array. STBI patient group was stratified using the Modified Rankin Score (mRS) into 3 groups: mRS 6 (died), mRS 5 (severely disabled) and mRS 1-4 (mild-to-moderately disabled) group. Analysis for bead array data using Kruskal-Wallis test with post hoc Dunn's multiple comparisons test, and temporal changes and correlation analysis using Spearman's correlation were carried out. At day 1 post-injury, CSF galectin-3 and interleukin-6 (IL-6), interleukin-10 (IL-10), cysteine-cysteine motif chemokine ligand-2 (CCL-2), and cysteine-cysteine motif chemokine ligand-20 (CCL-20), but not interleukin-1β (IL-1β) and tumor necrosis factor (TNF-α) levels were significantly elevated in mRS 5 group compared to non-TBI controls. Temporal correlation analysis at 1-7 days showed decreased IL-10 level in the mRS 6 group, decreased IL-10 and CCL-2 levels in mRS 5 group, and decreased IL-6, CCL-2, and CCL-20 levels in the mRS 1-4 group. Receiver operating characteristic curve analyses revealed a significant area under the curve for comparison between mRS 6 and mRS 5 groups for galectin-3 and IL-6. No significant differences in sex, age, Glasgow Coma Scale score, C-reactive protein levels and types of TBI-induced hemorrhages were observed between the groups. CSF galectin-3 and associated cytokines, especially IL-6, CCL-2 and CCL-20 levels were different within sub-groups of sTBI patients, suggesting their potential use in sTBI prognostics.

Mild Traumatic Brain Injury by the Glasgow Coma Scale Score and Early CT-Brain Findings in Acute Alcohol Intoxication Patients: A Prospective Observational Study.

Introduction Traumatic brain injuries (TBI) in recent years have proved to be a significant public health problem, with potentially life-changing consequences for the individual and their family. Alcohol consumption is a regular, well-documented problem among persons sustaining TBIdue to road traffic accidents and accidental falls. The primary objective of this study was to find out the correlation between the Glasgow Coma Scale (GCS) score and CT brain findings among mild TBI patients under acute alcohol intoxication and determine if early CT-brain is indicated in this group. Methods A prospective observational study was conducted involving 111 alcohol-intoxicated patients with mild head injuries admitted to the surgical wards of Thanjavur Medical College Hospitalover a period of three months. The Glasgow Coma Scale was used to assess the patient'sneurological status and determine the severity of the brain injury. A semi-structured CT-brain findings chart and a severity of alcohol intoxication objective-based scoring system were developed and validated by experts. Descriptive statistics tools such as frequency, percentage, and mean were used, along with inferential statistics tools like the Chi-squared test, Fisher exact test, and Pearson's correlation coefficient test. Results The study findings showed that the comparison of GCS with early CT-brain was significant at a p-value of 0.012, and a negative correlation (r=-0.253) was found between GCS and CT-brain findings. A comparison of CT-brain findings with the severity of alcohol intoxication was non-significant at a p-value of 0.433. Conclusions Early CT-brain in intoxicated mild TBI patients may have a positive impact on early diagnosis and management, even in centers with limited resources catering to low-income population groups. The results of our short-term study show that early CT-Brain picks up lesions and helps initiate early management while it is up to the attending physician to keep in mind an adverse cost-benefit ratio in overuse of hospital resources and misdiagnosis leading to undertreatment causing long-term sequelae and morbidity before prescribing early CT-brain in this cohort of patients.

Clinical and Etiological Profile of Children With Acute Viral Encephalitis in a Tertiary Care Hospital: A Cross-Sectional Study.

Acute encephalitis refers to the clinical diagnosis of children who have a sudden onset of symptoms and show evidence of inflammatory lesions in the brain. Timely diagnosis is crucial for both lifesaving measures and the preservation of brain functions. The objective of the study was to determine the clinical and etiological profile of acute viral encephalitis in children within a tertiary care hospital. This hospital-based cross-sectional study was conducted in the Pediatric Intensive Care Unit (PICU) at Dr. D. Y. Patil Medical College, Hospital, and Research Centre in Pune. The study included children aged one month to 12 years diagnosed with suspected viral encephalitis. Over 22 months, from August 2022 to June 2024, 35 children who met the inclusion criteria were enrolled. Data collection involved clinical examinations, laboratory investigations, and imaging studies, following informed consent from the parents or guardians. The study examined 35 patients with suspected acute encephalitis syndrome (AES) and found a male-to-female ratio of 3.4:1. Among the patients, 22 (62.85%) had a confirmed viral etiology, while 13 (37.17%) had an unknown etiology. The most common virus isolated was mumps, with school-age children most affected. The cases were concentrated in the Chikhali, Bhosari, Nigdi, and Chinchwad regions. Symptoms included fever, seizures, vomiting, and altered mental status. Low vaccination rates were observed, and the Glasgow Coma Scale (GCS) scores, shock incidence, and ventilation showed an association with mortality. Most patients required intensive care, antiedema measures, antibiotics, and antivirals. The mortality rate was 11.4%, with 17% of patients discharged with neurological sequelae. Causative agents such as mumps, herpes simplex virus (HSV), dengue, and many other viruses are now more prevalent than the Japanese encephalitis (JE) virus. Bad clinical course and fatal outcomes are observed in patients affected with rabies, HSV, and H1N1 influenza virus. Factors such as GCS scores, shock, and need for ventilation play a significant role in determining patient prognosis. Early detection and prompt treatment may aid in betteroutcomes for patients.

Intensive Care Unit Sleep Promotion Bundle: Impact on Sleep Quality, Delirium, and Other Patient Outcomes.

High-quality sleep is important for optimal patient recovery. Sleep deprivation during hospitalization may lead to poor patient outcomes. To examine whether implementation of a sleep promotion bundle in the intensive care unit affects rates of delirium and agitation, restraint use, and length of stay. An evidence-based sleep promotion bundle was developed and implemented in 2 intensive care units in a 1025-bed level I trauma teaching hospital. Deidentified data from the electronic health record were obtained for patients hospitalized before and during the intervention. Data included scores on the Confusion Assessment Method for the Intensive Care Unit, Richmond Agitation-Sedation Scale, and Glasgow Coma Scale; restraint use; and hospital and intensive care unit length of stay. A total of 137 patients during the preintervention period and 149 patients during the intervention period were hospitalized in the intensive care units and met inclusion criteria. A 9-percentage-point decrease in the incidence of delirium from before to during the intervention was found, although it was not statistically significant (P = .07). Significant reductions were found in both intensive care unit (P = .04) and hospital (P = .03) length of stay. A significant decrease was found in Richmond Agitation-Sedation Scale high scores for patients requiring mechanical ventilation (P = .03). No significant differences were found in Richmond Agitation-Sedation Scale low scores, Glasgow Coma Scale scores, or restraint use. Critical care nurses are in an optimal position to implement evidence-based sleep promotion measures. Further research on sleep promotion bundles is needed.

Automated Measurement of Cerebral Hemorrhagic Contusions and Outcomes After Traumatic Brain Injury in the TRACK-TBI Study

Because withdrawal of life-sustaining therapy based on perceived poor prognosis is the most common cause of death after moderate or severe traumatic brain injury (TBI), the accuracy of clinical prognoses is directly associated with mortality. Although the location of brain injury is known to be important for determining recovery potential after TBI, the best available prognostic models, such as the International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT) score, do not currently incorporate brain injury location. To test whether automated measurement of cerebral hemorrhagic contusion size and location is associated with improved prognostic performance of the IMPACT score. This prognostic cohort study was performed in 18 US level 1 trauma centers between February 26, 2014, and August 8, 2018. Adult participants aged 17 years or older from the US-based Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) study with moderate or severe TBI (Glasgow Coma Scale score 3-12) and contusions detected on brain computed tomography (CT) scans were included. The data analysis was performed between January 2023 and February 2024. Labeled contusions detected on CT scans using Brain Lesion Analysis and Segmentation Tool for Computed Tomography (BLAST-CT), a validated artificial intelligence algorithm. The primary outcome was a Glasgow Outcome Scale-Extended (GOSE) score of 4 or less at 6 months after injury. Whether frontal or temporal lobe contusion volumes improved the performance of the IMPACT score was tested using logistic regression and area under the receiver operating characteristic curve comparisons. Sparse canonical correlation analysis was used to generate a disability heat map to visualize the strongest brainwide associations with outcomes. The cohort included 291 patients with moderate or severe TBI and contusions (mean [SD] age, 42 [18] years; 221 [76%] male; median [IQR] emergency department arrival Glasgow Coma Scale score, 5 [3-10]). Only temporal contusion volumes improved the discrimination of the IMPACT score (area under the receiver operating characteristic curve, 0.86 vs 0.84; P = .03). The data-derived disability heat map of contusion locations showed that the strongest association with unfavorable outcomes was within the bilateral temporal and medial frontal lobes. These findings suggest that CT-based automated contusion measurement may be an immediately translatable strategy for improving TBI prognostic models.

Evaluating the effectiveness of immediate vs. elective thoracic endovascular aortic repair for blunt thoracic aortic injury

PurposeTo evaluate the relationship between the timing of thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) and prognosis. MethodsThis is a single-center retrospective cohort study. Patients who received TEVAR for BTAI at our institution from October 2016 to September 2023 were divided into 2 categories depending on the injury severity score (ISS) (≤ 25 vs. > 25) and when the TEVAR was performed for BTAI (within 24 h vs. after 24 h), respectively. The analysis included all patients who received TEVAR treatment after being diagnosed with BTAI through whole-body CT angiography. Patients treated with open repair and non-operative management were excluded. After propensity-score matching for various factors, outcomes during hospitalization and follow-up were compared. These factors included demographics, comorbidities, concomitant injuries, cause and location of aortic injury, Glasgow coma scale score, society for vascular surgery grading, hemoglobin concentration, creatinine concentration, shock, systolic blood pressure, and heart rate at admission. The comparison was conducted using SPSS 26 software. Continuous variables were presented as either the mean ± standard deviation or median (Q1, Q3), and were compared using either the t-test or the Mann-Whitney U test. Categorical variables were expressed as n (%), and comparisons were made between the 2 groups using the χ2 test or Fisher’s exact test. Statistical significance was defined as a 2-sided p < 0.05. ResultsIn total, 110 patients were involved in the study, with 65 (59.1%) patients having ISS scores > 25 and 32 (29.1%) receiving immediate TEVAR. The perioperative overall mortality rate in the group with ISS > 25 was significantly higher than that in the group with ISS ≤ 25 (11 (16.9%) vs. 2 (4.4%), p < 0.001). Upon admission, the elective group exhibited a notably higher Glasgow coma scale score (median (Q1, Q3)) compared to the immediate group (15 (12, 15) vs. 13.5 (9, 15), p = 0.039), while the creatinine concentration (median (Q1, Q3)) at admission was significantly higher in the immediate group (90.5 (63.8, 144.0) vs. 71.5 (58.3, 80.8), p = 0.012). The final sample included 52 matched patients. Complications occurred significantly less frequently in the elective group compared to the immediate group (16 (50.0%) vs. 3 (10.0%), p < 0.001). Single-factor analysis of variance showed that complications in hospitalized patients were significantly associated with immediate TEVAR as the sole independent risk factor (odds ratio: 9.000, 95% confidence interval: 2.266 – 35.752, p = 0.002). ConclusionIn this propensity-score matched analysis of patients undergoing TEVAR for BTAI, elective TEVAR was significantly associated with a lower risk of complication rates. In this study using propensity-score matching, patients who underwent elective TEVAR for BTAI had lower complication rates than immediate TEVAR.
