Abstract
Objective This work focused on investigating if robot-assisted minimally invasive surgery improved middle term vital outcome for primary brainstem hemorrhage (PBSH). Methods This work obtained clinical data from patients with PBSH admitted from July 2019 to August 2021. All cases were classified as surgical or conservative treatment group. The general information, Glasgow coma scale (GCS) score, Glasgow outcome score (GOS), along with survival time in patients 60 days after robot-assisted surgery were recorded and analyzed. Results A prospective analysis was performed on 82 cases meeting eligibility criteria, including 36 from surgical group whereas 46 from the conservative group. Sixty days after onset, the death rate was found to be 19.44% and 50.00% of surgical and conservative groups, separately (cases versus controls, P < 0.05). Furthermore, postoperative GOS and GCS scores of surgical group were significantly higher, and hydrocephalus was lower compared with conservative group. Central fever incidence did not exhibit any significant difference between two groups. Conclusion Robot-assisted PBSH drainage may improve survivorship and reduce the occurrence of hydrocephalus.

Abstract
Elevated pulse pressure is commonly observed in cardiovascular diseases and serves as an independent risk factor and predictor of cardiac mortality. However, the role of pulse pressure in patients with spontaneous intracerebral hemorrhage (ICH) remains uncertain. This study aimed to investigate the association between admission pulse pressure and clinical characteristics, including in-hospital outcomes, in ICH patients. We retrospectively analyzed the data of 292 ICH patients, categorizing them into two groups based on admission wide pulse pressure: > 100 mmHg (n = 60) and ≤ 100 mmHg (n = 232). Clinical characteristics and in-hospital outcomes were compared between the groups, and multivariate logistic regression was performed to identify independent factors. Patients with wide pulse pressure were older, had lower Glasgow Coma Scale, larger intraparenchymal hematomas, more pronounced midline shifts, and higher rates of intraventricular hematoma extension and hydrocephalus. These patients also experienced higher frequencies of craniotomy or craniectomy and longer hospital stays. Multivariate logistic regression revealed that pulse pressure > 100 mmHg was significantly associated with increased in-hospital mortality (odds ratio 4.31, 95% confidence interval 1.12-16.62, p = 0.03), but not with a modified Rankin Scale score of 4-6. In conclusion, our investigation demonstrates a significant relationship between admission pulse pressure and severe clinical characteristics in ICH patients. Importantly, a wider pulse pressure is linked to heightened in-hospital mortality. These results underscore the necessity for customized strategies to predict patient outcomes in this population. Further research is essential to explore potential therapeutic interventions targeting pulse pressure to improve clinical outcomes for ICH patients.

Abstract
OBJECTIVES A post-hoc analysis of the ICH Deferoxamine (i-DEF) trial was performed to examine any associations pre-ICH statin use may have with ICH volume, PHE volume, and clinical outcomes. MATERIALS AND METHODS Baseline characteristics were assessed. Various ICH and PHE parameters were measured via a quantitative, semi-automated method at baseline and follow-up CT scans 72-96 h later. A multivariable logistic regression model was created, adjusting for the variables that were significantly different on univariable analyses (p < 0.05), to assess any associations between pre-ICH statin use and measures of ICH and PHE, as well as good clinical outcome (mRS ≤2), at 90 and 180 days. RESULTS 262 of 291 i-DEF participants had complete data available for analysis. 69 (26.3 %) used statins prior to ICH onset. Pre-ICH statin users had higher prevalences of hypertension, diabetes, and prior ischemic stroke; higher concomitant use of antihypertensives and antiplatelets; and higher blood glucose level at baseline. On univariable analyses, pre-ICH statin users had smaller baseline ICH volume and PHE volume on repeat scan, as well as smaller changes in relative PHE (rPHE) volume and edema extension distance (EED) between the baseline and repeat scans. In the multivariable analysis, none of the ICH and PHE measures or good clinical outcome was significantly associated with pre-ICH statin use. CONCLUSION Pre-ICH statin use was not associated with measures of ICH or PHE, their growth, or clinical outcomes. These findings do not lend support to either overall protective or deleterious effects from statin use before or after ICH.

Abstract
Renal dysfunction has been reported to be associated with larger hematoma volume in intracerebral hemorrhage (ICH) due to concomitant nutritional imbalances and platelet dysfunction; however, this association remains controversial. This study analyzed the association between potential risk factors and hematoma volume in patients with ICH. This retrospective cohort study used data from 456 patients with ICH at a single comprehensive stroke center. We assessed the association of estimated glomerular filtration rate (eGFR) and Controlling Nutritional Status score with hematoma volume using multivariable non-linear regression models. The effect of the use of antithrombotic agents on hematoma volume was analyzed using outcome-adaptive double/debiased machine learning approach, considering many covariates. The median and interquartile range of age and eGFR were 64 (54-75) years and 56.1 (39.3-66.7) mL/min/1.73 m2, respectively. The multivariable non-linear regression model showed that (1) eGFR and hematoma volume had a positive linear association, which was not statistically significant, and (2) nutritional status was positively associated with hematoma volume, although not significantly. Outcome-adaptive double/debiased machine learning revealed that patients receiving antithrombotic agents did not present with significantly larger hematoma volume than those who were not receiving antithrombotic agents (estimated mean difference of hematoma volume [95% confidence interval] = 15.32 [-6.02 to 36.65]). Our analysis shows no statistically or clinically significant relationship between renal function and hematoma volume; however, nutritional status and the use of antithrombotic agents showed an increasing tendency of the degree of hematoma in patients with ICH.

Abstract
Background Studies of the impact of increased hemoglobin on spontaneous intracerebral hemorrhage (ICH) are limited. The present study aimed to explore the effect of increased hemoglobin on ICH. Methods A retrospective single-center study using medical records from a database processed by univariate and multivariate analyses was performed in the People’s Hospital of Tibet Autonomous Region in Lhasa, Tibet, China. Results The mean hemoglobin level in 211 patients with ICH was 165.03 ± 34.12 g/l, and a median hematoma volume was 18.5 ml. Eighty-eight (41.7%) patients had large hematomas (supratentorial hematoma ≥ 30 ml; infratentorial hematoma ≥ 10 ml). No differences in ICH risk factors between the groups with different hemoglobin levels were detected. Increased hemoglobin was independently associated with large hematomas [odds ratio (OR) 1.013, P = 0.023]. Increased hemoglobin was independently associated with ICH with subarachnoid hemorrhage (OR 1.014, P = 0.016), which was more pronounced in men (OR 1.027, P = 0.002). Increased hemoglobin was independently associated with basal ganglia hemorrhage and lobar hemorrhage in men (OR 0.986, P = 0.022; OR 1.013, P = 0.044, respectively) but not in women (P > 0.1). Conclusions Increased hemoglobin was independently associated with large hemorrhage volume. Increased hemoglobin was independently associated with lobar hemorrhage in men and ICH with subarachnoid hemorrhage, which was more pronounced in men. Additional studies are needed to confirm our findings and explore potential mechanisms.

Abstract
Background: We routinely measured the exact chronic subdural hematoma (CSDH) volume during single burr hole surgery. To date, several risk factors have been reported for CSDH recurrence, including sex, hematoma volume and degree of midline shift calculated from computed tomography, use of anticoagulants or antiplatelet medications, and alcohol consumption habits. The aim of this study was to clarify whether hematoma volume, in conjunction with other factors, can predict recurrence. Methods: We retrospectively reviewed the clinical data of 194 consecutive patients with CSDH who underwent single burr hole surgery. The risk factors for recurrence were analyzed based on patients’ sex, age, bilaterality, existence of apparent trauma history, exact intraoperative hematoma volume, and various clinical factors, including preoperative anticoagulant/antiplatelet intake. Results: Recurrence occurred in 22 patients (11.3%). Multivariate logistic regression analysis revealed that intraoperative hematoma volume was an independent risk factor for CSDH recurrence (odds ratio [OR], 1.01; 95% confidence interval [CI], 1.01–1.02, P < 0.001), in addition to sex (male) (OR 9.25; 95% CI, 1.00–84.8; P = 0.049) and diabetes mellitus (DM) (OR: 3.97, 95% CI, 1.34–11.7, P = 0.013). Based on receiver operating characteristics analysis, the cutoff value of the hematoma volume predicting CSDH recurrence was 150 ml (sensitivity and specificity of 72.7% and 72.1%, respectively; area under the curve: 0.7664, 95% CI: 0.654–0.879, P < 0.001). Of these, a hematoma volume ≥150 mL was the strongest independent risk factor for recurrence according to multiple regression (OR: 8.98, 95% CI: 2.73–29.6, P < 0.001) and Cox regression analysis (hazard ratio: 3.05, 95% CI: 1.18–7.87, log-rank P = 0.0046, P = 0.021). Follow-up periods after surgery were significantly longer for cases with recurrence than for non-recurrence cases (24.8 ± 11.5 vs. 15.9 ± 9.7 days), and the recurrence prediction cutoff value was 17 days, with a sensitivity and specificity of 83.1% and 68.2%, respectively (AUC: 0.7707, 95% CI: 0.6695–0.8720, P < 0.001). Conclusion: Intraoperative hematoma volume could be a predictive value for CSDH recurrence.

Abstract
BACKGROUND Rapid diagnosis and proper management of intracerebral hemorrhage (ICH) play a crucial role in the outcome. Prediction of the outcome with a high degree of accuracy based on admission data including imaging information can potentially influence clinical decision-making practice. METHODS We conducted a retrospective multicenter study of consecutive ICH patients admitted between 2012-2017. Medical history, admission data, and initial head computed tomography (CT) scan were collected. CT scans were semiautomatically segmented for hematoma volume, hematoma density histograms, and sphericity index (SI). Discharge unfavorable outcomes were defined as death or severe disability (modified Rankin Scores 4-6). We compared (1) hematoma volume alone; (2) multiparameter imaging data including hematoma volume, location, density heterogeneity, SI, and midline shift; and (3) multiparameter imaging data with clinical information available on admission for ICH outcome prediction. Multivariate analysis and predictive modeling were used to determine the significance of hematoma characteristics on the outcome. RESULTS We included 430 subjects in this analysis. Models using automated hematoma segmentation showed incremental predictive accuracies for in-hospital mortality using hematoma volume only: area under the curve (AUC): 0.85 [0.76-0.93], multiparameter imaging data (hematoma volume, location, CT density, SI, and midline shift): AUC: 0.91 [0.86-0.97], and multiparameter imaging data plus clinical information on admission (Glasgow Coma Scale (GCS) score and age): AUC: 0.94 [0.89-0.99]. Similarly, severe disability predictive accuracy varied from AUC: 0.84 [0.76-0.93] for volume-only model to AUC: 0.88 [0.80-0.95] for imaging data models and AUC: 0.92 [0.86-0.98] for imaging plus clinical predictors. CONCLUSIONS Multiparameter models combining imaging and admission clinical data show high accuracy for predicting discharge unfavorable outcome after ICH.

Abstract
BACKGROUND Oxidative stress and inflammation play important roles in the neuronal injury caused by intracerebral hemorrhage (ICH). Uric acid (UA), an important natural antioxidant, might reduce the neuronal injury caused by ICH. Delineating the relationship between UA and ICH will enhance our understanding of antioxidative mechanisms in recovery from ICH. METHODS We conducted a retrospective study of 325 patients with acute supratentorial ICH to investigate the relationship between serum UA levels and hematoma volumes and prognosis. A hematoma volume of ≥30 mL was defined as a large hematoma. An unfavorable outcome was defined as a modified Rankin scale score of 4-6 on day 30. RESULTS The serum UA level was significantly lower in the patients with a large hematoma volume (median, 306 μmol/L; 25th to 75th percentile, 243-411 μmol/L) than in those with a small hematoma volume (median, 357 μmol/L; 25th to 75th percentile, 271-442 μmol/L; P = 0.012). Similarly, the unfavorable outcome group had had lower serum UA levels (median, 309 vs. 363 μmol/L; P = 0.009) compared with the favorable outcome group. The results of the multivariate logistic analysis indicated that a lower serum UA level was associated with a larger hematoma volume (odds ratio, 0.996; P = 0.006) and an unfavorable outcome (odds ratio, 0.997; P = 0.030). CONCLUSIONS The results from the present study have indicated that in patients with acute supratentorial ICH, a low serum UA level might indicate that the patient has a large hematoma volume and might be a risk factor for a poor day 30 functional prognosis.

Abstract
BACKGROUND Early systolic blood pressure (SBP) reduction is believed to improve outcome after spontaneous intracerebral hemorrhage (ICH), but there has been a limited assessment of SBP trajectories in individual patients. We aimed to determine the prognostic significance of SBP trajectories in ICH. METHODS We collected routine data on spontaneous ICH patients from two healthcare systems over 10 years. Unsupervised functional principal components analysis (FPCA) was used to characterize SBP trajectories over first 24 h and their relationship to the primary outcome of unfavorable shift on modified Rankin scale (mRS) at hospital discharge, categorized as an ordinal trichotomous variable (mRS 0-2, 3-4, and 5-6 defined as good, poor, and severe, respectively). Ordinal logistic regression models adjusted for baseline SBP and ICH volume were used to determine the prognostic significance of SBP trajectories. RESULTS The 757 patients included in the study were 65 ± 23 years old, 56% were men, with a median (IQR) Glasgow come scale of 14 (8). FPCA revealed that mean SBP over 24 h and SBP reduction within the first 6 h accounted for 76.8% of the variation in SBP trajectories. An increase in SBP reduction (per 10 mmHg) was significantly associated with unfavorable outcomes defined as mRS > 2 (adjusted-OR = 1.134; 95% CI 1.044-1.233, P = 0.003). Compared with SBP reduction < 20 mmHg, worse outcomes were observed for SBP reduction = 40-60 mmHg (adjusted-OR = 1.940, 95% CI 1.129-3.353, P = 0.017) and > 60 mmHg, (adjusted-OR = 1.965, 95% CI 1.011, 3.846, P = 0.047). Furthermore, the association of SBP reduction and outcome varied according to initial hematoma volume. Smaller SBP reduction was associated with good outcome (mRS 0-2) in small (< 7.42 mL) and medium-size (≥ 7.42 and < 30.47 mL) hematomas. Furthermore, while the likelihood of good outcome was low in those with large hematomas (≥ 30.47 mL), smaller SBP reduction was associated with decreasing probability of severe outcome (mRS 5-6). CONCLUSION Our analyses suggest that in the first 6 h SBP reduction is significantly associated with the in-hospital outcome that varies with initial hematoma volume, and early SBP reduction > 40 mmHg may be harmful in ICH patients. For early SBP reduction to have an effective therapeutic effect, both target levels and optimum SBP reduction goals vis-à-vis hematoma volume should be considered.

Abstract
The volume of pelvic hematoma at CT has been shown to be the strongest independent predictor of major arterial injury requiring angioembolization in trauma victims with pelvic fractures, and also correlates with transfusion requirement and mortality. Measurement of pelvic hematomas (unopacified extraperitoneal blood accumulated from time of injury) using semi-automated seeded region growing is time-consuming and requires trained experts, precluding routine measurement at the point of care. Pelvic hematomas are markedly variable in shape and location, have irregular ill-defined margins, have low contrast with respect to viscera and muscle, and reside within anatomically distorted pelvises. Furthermore, pelvic hematomas occupy a small proportion of the entire volume of a chest, abdomen, and pelvis (C/A/P) trauma CT. The challenges are many, and no automated methods for segmentation and volumetric analysis have been described to date. Traditional approaches using fully convolutional networks result in coarse segmentations and class imbalance with suboptimal convergence. In this study, we implement a modified coarse-to-fine deep learning approach-the Recurrent Saliency Transformation Network (RSTN) for pelvic hematoma volume segmentation. RSTN previously yielded excellent results in pancreas segmentation, where low contrast with adjacent structures, small target volume, variable location, and fine contours are also problematic. We have curated a unique single-institution corpus of 253 C/A/P admission trauma CT studies in patients with bleeding pelvic fractures with manually labeled pelvic hematomas. We hypothesized that RSTN would result in sufficiently high Dice similarity coefficients to facilitate accurate and objective volumetric measurements for outcome prediction (arterial injury requiring angioembolization). Cases were separated into five combinations of training and test sets in an 80/20 split and fivefold cross-validation was performed. Dice scores in the test set were 0.71 (SD ± 0.10) using RSTN, compared to 0.49 (SD ± 0.16) using a baseline Deep Learning Tool Kit (DLTK) reference 3D U-Net architecture. Mean inference segmentation time for RSTN was 0.90 min (± 0.26). Pearson correlation between predicted and manual labels was 0.95 with p < 0.0001. Measurement bias was within 10 mL. AUC of hematoma volumes for predicting need for angioembolization was 0.81 (predicted) versus 0.80 (manual). Qualitatively, predicted labels closely followed hematoma contours and avoided muscle and displaced viscera. Further work will involve validation using a federated dataset and incorporation into a predictive model using multiple segmented features.

Abstract
PURPOSE To introduced our experience with progressive extra-axial hematoma (EAH) in the original frontotemporoparietal (FTP) site after contralateral decompressive surgery (CDS) in traumatic brain injury patients and discuss the risk factors associated with this dangerous situation. METHODS This retrospective study was conducted on 941 patients with moderate or severe TBI treated in Daping Hospital, Army Medical University, Chongqing, China in a period over 5 years (2013-2017). Only patients with bilateral lesion, the contralateral side being the dominant lesion, and decompressive surgery on the contralateral side conducted firstly were included. Patients were exclude if (1) they underwent bilateral decompression or neurosurgery at the original location firstly; (2) although surgery was performed first on the contralateral side, surgery was done again at the contralateral side due to re-bleeding or complications; (3) patients younger than 18 years or older than 80 years; and (4) patients with other significant organ injury or severe disorder or those with abnormal coagulation profiles. Clinical and radiographic variables reviewed were demographic data, trauma mechanisms, neurological condition assessed by Glasgow coma scale (GCS) score at admission, pupil size and reactivity, use of mannitol, time interval from trauma to surgery, Rotterdam CT classification, type and volume of EAH, presence of a skull fracture overlying the EAH, status of basal cistern, size of midline shift, associated brain lesions and types, etc. Patients were followed-up for at least 6 months and the outcome was graded by Glasgow outcome scale (GOS) score as favorable (scores of 4-5) and unfavorable (scores of 1-3). Student's t-test was adopted for quantitative variables while Pearson Chi-squared test or Fisher's exact test for categorical variables. Multivariate logistic regression analysis was also applied to estimate the significance of risk factors. RESULTS Initially 186 patients (19.8%) with original impact locations at the FTP site and underwent surgery were selected. Among them, 66 met the inclusion and exclusion criteria. But only 50 patients were included because the data of the other 16 patients were incomplete. Progressive EAH developed at the original FTP site in 11 patients after the treatment of, with an incidence of 22%. Therefore the other 39 patients were classified as the control group. Multivariate logistic regression analysis showed that both the volume of the original hematoma and the absence of an apparent midline shift were significant predictors of hematoma progression after decompressive surgery. Patients with fracture at the original impact site had a higher incidence of progressive EAH after CDS, however this factor was not an important predictor in the multivariate model. We also found that patients with progressive EAH had a similar favorable outcome with control group. CONCLUSION Progressive EAH is correlated with several variables, such as hematoma volumes ≥10 mL at the original impact location and the absence of an apparent midline shift (<5 mm). Although progressive EAH is devastating, timely diagnosis with computed tomography scans and immediate evacuation of the progressive hematoma can yield a favorable result.

Abstract
Chronic subdural hematoma (CSDH) is a common disease in older individuals with a substantial rate of recurrence. The mechanism of CSDH recurrence remains unclear. This study aimed to detect imaging parameters that could indicate the risk for CSDH recurrence by using quantitative volumetric analysis and computed tomography (CT) texture analysis (CTTA). Clinical and imaging parameters were retrospectively investigated in 147 newly diagnosed CSDH lesions in 114 patients surgically treated at the Keio University Hospital during a 6-year period. For CT images, quantitative volumetric and texture analyses were performed. Hematoma volume, postoperative air volume, hematoma density, and texture parameters including kurtosis, skewness, and entropy were evaluated and compared with CSDH recurrence rate. Data were statistically evaluated, and a difference of p < 0.05 was considered significant. Reoperation for CSDH recurrence was required in 27 sides (18.4%) of 26 patients. Multivariate analysis showed that postoperative hematoma volume and postoperative hematoma density were independent risk factors for symptomatic CSDH recurrence that required reoperation. Postoperative hematoma volume, postoperative significant residual air, and postoperative hematoma density were also identified as independent risk factors for potential CSDH recurrence. Preoperative hematoma entropy was prone to be associated with both symptomatic and potential CSDH recurrence in univariate analysis, but not in multivariate analysis because of confounding factors. Quantitative volumetric analysis and CTTA could aid in distinguishing individuals at risk for CSDH recurrence.

Abstract
Simulating a clinical condition of intracerebral hemorrhage (ICH) in animals is key to research on the development and testing of diagnostic or treatment strategies for this high-mortality disease. In order to study the mechanism, pathology, and treatment for hemorrhagic stroke, various animal models have been developed. Measurement of hematoma volume is an important assessment parameter to evaluate post-ICH outcomes. However, due to tissue preservation conditions and variables in digitization, quantification of hematoma volume is usually labor intensive and sometimes even subjective. The objective of this study is to develop an automated method that can accurately and efficiently obtain unbiased cerebral hematoma volume. We developed an application (MATLAB program) that can delineate the brain slice from the background and use the Hue information in the Hue/Saturation/Value (HSV) color space to segment the hematoma region. The segmentation threshold of Hue is calculated based on the Bayes classifier theorem so that the minimum error is mathematically ensured and automated processing is enabled. To validate the developed method, we compared the outcomes from the developed method with the hemoglobin content by the spectrophotometric assay method. The results were linearly correlated with statistical significance. The method was also validated by digital phantoms with an error less than 5% compared with the ground truth from the phantoms. Hematoma volumes yielded by the automated processing and those obtained by the operator's manual operation are highly correlated. This automated segmentation approach can be potentially used to quantify hemorrhagic outcomes in rodent stroke models in an unbiased and efficient way.

Abstract
OBJECTIVE To test whether robot-assisted surgery can improve prognosis of small-volume thalamic hemorrhage and to provide a surgical basis for treatment of small-volume thalamic hemorrhage. METHODS This retrospective study included patients with thalamic hemorrhage and hematoma volume of 5-15 mL treated from December 2015 to December 2018. Patients were divided into an operation group and a nonoperation group. General data, types of hematoma, incidence of complications, Scandinavian Stroke Scale score, and modified Rankin Scale score were recorded and analyzed. RESULTS Retrospectively, 84 cases met inclusion criteria: 35 cases in operation group and 49 cases in nonoperation group. At 90 days after onset, mortality was 11.4% in the operation group and 4.1% in the nonoperation group (P > 0.05). The Scandinavian Stroke Scale score in the operation group (43.3 ± 8.5) was higher than in the nonoperation group (36.1 ± 10.0) (P < 0.05). The modified Rankin Scale score in the operation group (2.9 ± 0.3) was lower than in the nonoperation group (3.7 ± 0.2) (P < 0.05). The incidence of pneumonia (8.6%) and renal dysfunction (14.3%) was lower in the operation group than in the nonoperation group (28.6% and 34.7%, respectively) (P < 0.05). There was no significant difference between the 2 groups in the incidence of central fever (5.7% vs. 12.2%), stress ulcer (11.4% vs. 16.3%), and ion balance disturbance (20.0% vs. 26.5%) (P > 0.05). CONCLUSIONS Robot-assisted drainage of thalamic hemorrhage can improve prognosis and reduce the incidence of pneumonia and renal dysfunction.

Abstract
BACKGROUND Prognostic significance of serum calcium level in patients with intracerebral hemorrhage is not well studied. The aim of the study was to identify if a relationship between admission serum calcium level and prognosis exists in patients with intracerebral hemorrhage. METHODS A total of 1262 confirmed intracerebral hemorrhage patients were included. Demographic data, medical history, medicine history, laboratory data, imaging data, clinical score, and progress note were collected from their medical records. All images of head computed tomography were reanalyzed. Ninety-day prognosis was recorded, and poor outcome was defined as death or major disability caused by intracerebral hemorrhage. RESULTS During the 90-day follow-up period, 504 patients died and 226 patients suffered from major disability. Death and major disability were combined as poor prognosis. The remaining 532 patients showed good prognosis. Admission serum calcium level was lower in the patients with poor prognosis than in the patients with good prognosis (2.41 ± 0.23 mmol/l, 2.55 ± 0.26 mmol/l, P < 0.001). Admission INR and hematoma volume were higher in the patients with poor prognosis than in the patients with good prognosis (INR: 1.74 ± 0.29, 1.70 ± 0.29, P = 0.029; hematoma volume: 11.6 ± 4.4 ml, 10.7 ± 4.1 ml, P < 0.001). There was no difference in admission APTT level between the two prognosis groups (28.4 ± 5.6 s, 27.8 ± 5.4 s, P = 0.056). A multivariate COX regression analysis reported that admission serum calcium level ≤ 2.41 mmol/l was associated with the increased risk of poor prognosis (death or major disability) in the patients (HR 1.45, 95% CI 1.32-1.60). In addition, there was a significant linear association of serum calcium level with coagulation function markers and hematoma volume on admission (APTT: r = - 0.091, P = 0.001; INR: r = - 0.063, P = 0.025; hematoma volume: r = -0.108, P < 0.001). CONCLUSIONS Admission serum calcium level might be a prognostic marker for intracerebral hemorrhage. Potential mechanism involved calcium-induced coagulation function abnormality.

Abstract
OBJECTIVES The effect of a direct-acting oral anticoagulant (DOAC) dose on intracerebral hemorrhage (ICH) severity and outcome remains unclear. The aim of this study is to clarify the frequency of off-label dosing of DOAC treatments in ICH patients and compare clinical characteristics. PATIENTS AND METHODS We studied 43 patients with ICH who were treated with DOAC for nonvalvular atrial fibrillation before the onset of ICH. DOAC treatments were categorized into three groups based on the following doses: optimal dose, under-dose, and overdose. RESULTS Overall, 31 patients were optimally dosed, 10 were under-dosed, and 2 were overdosed. CHADS2 and CHA2DS2-VASc scores were the highest in the overdose group (median, 4, 6, respectively) and the lowest in the optimal dose group (median, 2, 4, respectively) (p = 0.006, p = 0.005, respectively). ICH severity measured using the National Institutes of Health Stroke Scale scores was the highest in the overdose group (median, 26.5) and the lowest in the under-dose group (median, 6.5) (p = 0.244). Larger initial hematoma volume was observed in the overdose group. The ratio of good outcome (modified Rankin Scale score ≤ 2) was higher in the under-dose group (40%) than the other groups, but this difference was not significant. CONCLUSION Our study shows only a few patients received overdosing of a DOAC before the onset of ICH, and they were associated with poorer functional outcomes. Conversely, under-dosing was associated with better functional outcomes than the other groups.

Abstract
OBJECTIVE Multiple simultaneous intracerebral hemorrhages (MSICH) are a rare clinical entity. The mechanism and risk factors have yet to be elucidated. The purpose of this study was to clarify clinical presentations and risk factors of MSICH compared with solitary intracerebral hemorrhages (ICH). PATIENTS AND METHODS Medical records of 313 consecutive patients with ICH admitted to our institution between April 2011 and September 2014 were retrospectively reviewed. Seventeen cases of MSICH were identified, and 10 clinical and neuroimaging variables were compared between MSICH cases and solitary ICH cases using the unpaired t-test, chi-square test, and multiple logistic regression analysis. RESULTS There were significant differences in size between larger hematomas (mean 59.2±69.1mL) and smaller hematomas (mean 1.7±2.1mL) in patients with MSICH (p=0.001). Larger hematoma volume was the only independent risk factor for MSICH in multiple logistic regression analysis (OR=1.012, 95%CI 1.004-1.021, p=0.004). CONCLUSIONS Patients with MSICH have clinical characteristics and outcomes similar to patients with solitary ICH. They present with two significantly different hematoma sizes, both of which are significantly larger than patients with solitary ICH, suggesting that a larger hematoma can trigger smaller hematomas. A future prospective study with a larger number of patients will explore the precise mechanism of this rare entity.

Abstract
Objective To explore predictors of the 6-month clinical outcome of thalamic hemorrhage, and evaluate if minimally invasive thalamic hematoma drainage (THD) could improve its prognosis. Methods A total of 54 patients with spontaneous thalamic hemorrhage were evaluated retrospectively. Clinical data, including demographics, stroke risk factors, neuroimaging variables, Glasgow Coma Score (GCS) on admission, surgical strategy, and outcome, were collected. Clinical outcome was assessed using a modified Rankin Scale, six months after onset. Univariate analysis and multivariate logistic regression analysis were performed to determine predictors of a poor outcome. Results Conservative treatment was performed for five patients (9.3%), external ventricular drainage (EVD) for 20 patients (37.0%), THD for four patients (7.4%), and EVD combined with THD for 25 patients (46.3%). At six months after onset, 21 (38.9%) patients achieved a favorable outcome, while 33 (61.1%) had a poor outcome. In the univariate analysis, predictors of poor 6-month outcome were lower GCS on admission (P = 0.001), larger hematoma volume (P < 0.001), midline shift (P = 0.035), acute hydrocephalus (P = 0.039), and no THD (P = 0.037). The independent predictors of poor outcome, according to the multivariate logistic regression analysis, were no THD and larger hematoma volume. Conclusions Minimally invasive THD, which removes most of the hematoma within a few days, with limited damage to perihematomal brain tissue, improved the 6-month outcome of thalamic hemorrhage. Thus, THD can be widely applied to treat patients with thalamic hemorrhage.

Abstract
BACKGROUND Twist drill craniostomy (TDC) is a minimally invasive and cost-effective technique to treat chronic subdural hematomas (CSDHs). Predictors for treatment success such as imaging characteristics, hematoma volume, and drainage volume are not established; thus, they are purpose of this analysis. MATERIAL AND METHODS We retrospectively evaluated all data of patients with CSDH undergoing TDC in our institution between January 2010 and December 2013. We analyzed imaging characteristics (extension and composition), volumetrically calculated pre- and postoperative hematoma volumes, measured drainage volume, and clinical course. Primary treatment success was defined as sufficient if definitive treatment was achieved via a single TDC (TDC-1) and insufficient if more than one TDC was needed. The need for open surgical evacuation was defined as treatment failure. RESULTS Data of 233 patients undergoing 387 TDCs were available for our study. A total of 67% of TDCs treated CSDHs effectively, whereas the remainder required further open surgical evacuation. Via use of the median-split-method, we found that sufficient treatment was achieved more frequently in smaller hematomas (P < 0.05). Treatment effectiveness was neither correlated with hematoma image characteristics (presence of membranes: P = 0.11, extent of chronification: P = 0.55) nor with the respective drainage volume (P = 0.95). Residual hematoma volume was consistently greater than expected by drainage calculation (P < 0.05). CONCLUSIONS TDC is an effective treatment option for CSDH. Sufficient treatment with single TDC was more common in smaller hematomas with an associated smaller residual hematoma. Failure of brain re-expansion after TDC may increase the treatment failure rates. In these cases, an open surgical evacuation might accelerate treatment and clinical recovery.

Abstract
BACKGROUND Neutrophil to lymphocyte ratio (NLR) serves as a powerful inflammatory marker for predicting cardiovascular events. Here, we investigate whether admission NLR is associated with hematoma volume, stroke severity, and 3-month outcomes in patients with acute intracerebral hemorrhage (ICH). METHODS 352 patients with acute ICH were prospectively identified in this study. Demographic characteristics, lifestyle risk factors, NIHSS score, hematoma volumes, and other clinical features were recorded for all participants. Patients was divided into quartiles based on the admission NLR levels (Q1: <2.78; Q2: 2.78-4.08; Q3: 4.08-7.85; Q4: ≥7.85). Multivariable linear regression models and logistic regression models were used to evaluate the association between NLR and hematoma volume, admission severity, or the outcomes after ICH. RESULTS Median NIHSS scores for each quartile (Q1 to Q4) were 6.0, 6.0, 6.0, and 11.0 (P=.001), and median hematoma volumes were 9.5, 9.3, 9.1, and 15.0ml (P=.005), respectively. After adjusting the age, sex, and other potential risk factors, the patients in Q4 had higher NIHSS scores (P=.042) and larger hematoma volume (P=.014). After 3-month follow-up, 148 poor outcomes (mRS, 3-6) and 47 all-cause deaths were documented. There were more patients with poor outcomes in Q4 than Q1. However, compared with the patients in Q1, those in Q4 were not associated with poor outcomes (P-trend=0.379), and all-cause mortality (P-trend=0.843) after adjust for other risk factors. CONCLUSIONS Higher admission NLR are associated with larger hematoma volume and more serious stroke, but not 3-month outcomes in patients with acute ICH.

Abstract
OBJECTIVE Manually segmented traumatic pelvic hematoma volumes are strongly predictive of active bleeding at conventional angiography, but the method is time intensive, limiting its clinical applicability. We compared volumetric analysis using semi-automated region growing segmentation to manual segmentation and diameter-based size estimates in patients with pelvic hematomas after blunt pelvic trauma. MATERIALS AND METHODS A 14-patient cohort was selected in an anonymous randomized fashion from a dataset of patients with pelvic binders at MDCT, collected retrospectively as part of a HIPAA-compliant IRB-approved study from January 2008 to December 2013. To evaluate intermethod differences, one reader (R1) performed three volume measurements using the manual technique and three volume measurements using the semi-automated technique. To evaluate interobserver differences for semi-automated segmentation, a second reader (R2) performed three semi-automated measurements. One-way analysis of variance was used to compare differences in mean volumes. Time effort was also compared. Correlation between the two methods as well as two shorthand appraisals (greatest diameter, and the ABC/2 method for estimating ellipsoid volumes) was assessed with Spearman's rho (r). RESULTS Intraobserver variability was lower for semi-automated compared to manual segmentation, with standard deviations ranging between ±5-32 mL and ±17-84 mL, respectively (p = 0.0003). There was no significant difference in mean volumes between the two readers' semi-automated measurements (p = 0.83); however, means were lower for the semi-automated compared with the manual technique (manual: mean and SD 309.6 ± 139 mL; R1 semi-auto: 229.6 ± 88.2 mL, p = 0.004; R2 semi-auto: 243.79 ± 99.7 mL, p = 0.021). Despite differences in means, the correlation between the two methods was very strong and highly significant (r = 0.91, p < 0.001). Correlations with diameter-based methods were only moderate and nonsignificant. Mean semi-automated segmentation time effort was 2 min and 6 s and 2 min and 35 s for R1 and R2, respectively, vs. 22 min and 8 s for manual segmentation. CONCLUSION Semi-automated pelvic hematoma volumes correlate strongly with manually segmented volumes. Since semi-automated segmentation can be performed reliably and efficiently, volumetric analysis of traumatic pelvic hematomas is potentially valuable at the point-of-care.

Abstract
The aim of this study is to analyze the association of preoperative usage of angiotensin converting enzyme (ACE) inhibitors with the initial presentation and clinical outcome of patients with chronic subdural hematoma (cSDH). Patients treated for cSDH between 2009 and 2013 at our institution were included in this retrospective case-control study. Medical charts were reviewed retrospectively and data were analyzed using descriptive and inferential statistics. Out of 203 patients (58 females, mean age 73.2years), 53 (26%) patients were on ACE inhibitors before their presentation with cSDH. Median initial hematoma volume in individuals with ACE inhibitors (179.2±standard error of the mean [SEM] 13.0ml) was significantly higher compared to patients without ACE inhibitors (140.4±SEM 6.2ml; p=0.007). There was an increased probability of surgical reintervention in the ACE inhibitor group (12/53, 23% versus 19/153, 12%; p=0.079), especially in patients older than 80years (6/23, 26% versus 3/45, 7%; p=0.026). ACE inhibitors are associated with higher hematoma volume in patients with cSDH and with a higher frequency of recurrences requiring surgery (especially in the very old). We hypothesize that these effects are due to ACE inhibitor induced bradykinin elevation causing increased vascular permeability of the highly vascularized neomembranes in cSDH.

Abstract
Background: Spontaneous intracerebral hemorrhage (SICH) is a form of cerebrovascular accident with a very high rate of morbidity and mortality. The determinants of prognosis include the demographic, clinical, laboratory, and radiologic factors. It is long known that the hematoma size has a negative impact on the outcome in SICH. The influence of perihematomal edema (PHE) is not established to the extent same as that of hematoma volume. Hence, we planned this study to determine as to what role does PHE plays in the outcome in SICH. Aim of the Study: To evaluate the prognostic influence of absolute and relative edema (ratio of absolute edema to hematoma volume) in the patients of SICH. Materials and Methods: This is a prospective case-controlled study. A total of 44 patients were enrolled after excluding the confounding factors. The patients were evaluated and their disability was assessed using modified Rankin scale (MRS). The imaging was done in the interval between 24 and 72 h and the hematoma volume, absolute edema volume, and the relative edema were calculated. The outcome was reassessed at 12 weeks and defined as favorable if MRS < 3. Results: A total of 69 patients were found to be having SICH on imaging; however, 25 patients were excluded as they had one of the criterion for exclusion. Hence, only 44 patients were included in the study. On univariate analysis, none of the demographic characteristics of the patients, vascular risk factors, presenting complaints, blood pressure, Glasgow coma scale, and MRS at admission, laboratory parameters were not significantly different in the two outcome groups. The hematoma volume was significantly higher in the poor outcome group (P < 0.0001) and the relative edema was associated with a favorable outcome at 12 weeks (P < 0.0001). On multivariate logistic regression, the hematoma volume and relative edema were found to have effect on the outcome similar to that seen on univariate analysis. Conclusion: In SICH, a larger hematoma volume is a predictor of poor outcome and a relative edema is associated with a better functional status.

Abstract
Gait analysis is a systematic collection of quantitative information on bodily movements during locomotion. Gait analysis has been employed clinically in stroke patients for their rehabilitation planning. In animal studies, gait analysis has been employed for the assessment of their locomotive disturbances in ischemic stroke, spinal cord injury and Parkinson's disease. The aims of the work reported here were to identify the gait parameters, collected from the computer-generated CatWalk System, that change after unilateral intracerebral hemorrhage (ICH) in the acute stage and long term up to 56 days post-ICH. The results showed that with the collagenase-induced unilateral striatal lesion, the rats displayed a significant contralateral decrease in print and maximum contact area and paw intensity, a diagonal increase in the stance duration of the left front and right hind paws, a significant decrease in the stride length of all four limbs, and foot pattern instability as reflected by the base of support, support on styles, and cadence. These deficits, including those in print area, stance and pressure, were demonstrated throughout the long-term period following ICH. The correlations between the gait parameters, lesion volume and asymmetrical forelimb use were also reported in this paper. This work has provided a systematic description on gait parameters in the classical striatal ICH model, which might become an essential assessment tool in future studies of pathophysiology and the development of novel treatments for experimental unilateral intracerebral hemorrhage with gait deficits.
