The impact of systolic blood pressure reduction on aneurysm re-bleeding in subarachnoid hemorrhage: A systematic review and meta-analysis

BackgroundPreventing early aneurysm rebleeding is crucial in the management of aneurysmal subarachnoid hemorrhage (SAH). Lowering systolic blood pressure (SBP) has been proposed as a potential strategy, but the evidence remains inconclusive. This systematic review and meta-analysis aimed to determine if a specific SBP target could reduce the risk of aneurysm rebleeding prior to treatment. MethodsElectronic databases were systematically searched for studies comparing SBP between SAH patients with and without aneurysm rebleeding before surgical treatment. Data on SBP values, patient characteristics, and rebleeding events were extracted. Meta-analyses were performed to pool mean SBP differences and odds ratios (ORs) for rebleeding at different SBP cut-offs. ResultsTen studies were included in the systematic review. Pooled data from the included studies showed that the mean SBP was higher in the rebleeding group (mean difference 5.89, 95 % CI 1.94 to 9.85). SBP ≤160 mmHg was associated with lower rebleeding risk (OR 0.30, 95 % CI 0.14 to 0.65). However, substantial heterogeneity and limitations in study designs and definitions were noted. ConclusionsThis meta-analysis suggests that SAH patients with rebleeding may present with higher SBP. However, the findings should be interpreted cautiously due to study limitations. Future prospective studies with standardized definitions and comprehensive data collection are needed to elucidate the complex relationship between blood pressure dynamics and rebleeding risk in SAH.

Effect of sarcopenia on liver cirrhosis with complicating oesophageal and gastric varices after endoscopic therapy

Several investigators have reported that sarcopenia is common in patients with liver cirrhosis. However, few studies have probed the association between sarcopenia and liver cirrhosis complicated with oesophageal and gastric variceal bleeding (LC-EGVB). We aimed to investigate the impact of sarcopenia on rebleeding after endoscopic therapy in patients with LC-EGVB. Computed tomography (CT) radiographs from the third lumbar vertebra were selected to analyse body composition, including skeletal muscle tissue, visceral and subcutaneous adipose tissue using SliceOmatic software. Sarcopenia was defined using validated cutoff values for patients with liver cirrhosis: 44.77 cm2/m2 for men and 32.50 cm2/m2 for women. A total of 187 patients with LC-EGVB and 309 controls were included in this study. The rate of sarcopenia in controls (17.4 %) was significantly lower than that in patients with LC-EGVB (41.2 %). Patients with LC-EGVB exhibiting sarcopenia showed a high prevalence of portal vein thrombosis and rebleeding rate at 1 year. The rate of sarcopenia in the rebleeding group was significantly higher than that in the non-rebleeding group. Univariate and multivariate analyses showed that sarcopenia was an independent risk factor for rebleeding within 1 year in patients with LC-EGVB. Patients with LC-EGVB displayed a high prevalence of sarcopenia. Sarcopenia was observed to be an independent risk factor for rebleeding within 1 year.

Application of a virtual ruler in predicting postoperative rebleeding from esophageal varices in patients with liver cirrhosis

BackgroundEsophageal variceal diameter (EVD) is one of the most important predictors of variceal bleeding, as well as an important predictor of the effectiveness of endoscopic esophageal varices (EV) treatments. EVD is currently determined using visual inspection by endoscopic operators, meaning that results can vary widely between operators. This approach also means that cases unsuitable for endoscopic variceal ligation (EVL) can be complicated by postoperative hemorrhage. Thus, the purpose of this study was to explore the value of a virtual ruler (VR) in predicting rebleeding after the endoscopic treatment of EV in patients with cirrhosis. MethodsWe enrolled 588 patients with cirrhosis and EV (with and without gastric varices), who were treated with EVL or endoscopic injection sclerotherapy across 3 hospitals. We categorized participants into 2 groups, a nonbleeding group and a rebleeding group, according to whether they bled again after surgery. We compared basic demographic and clinical data, laboratory tests, EVD, and treatment modalities between the 2 groups. Potential risk factors for rebleeding after EV operations were analyzed using univariate and multivariable regression analyses. Correlations between esophageal variceal rebleeding and EVD were also analyzed, as was the consistency between visual EVD estimates and EVD measured using a VR. ResultsChild-Pugh class, albumin (ALB) levels, prothrombin time (PT), EVD (visual value), EVD (VR value), red sign, and the number of laps used for EVL showed statistically significant differences between the rebleeding and nonbleeding groups. Univariate regression analysis showed that Child-Pugh classification, ALB levels, PT, EVD (VR value), and red sign were strongly associated with rebleeding after endoscopic treatment of EV, whereas multivariable regression analysis showed that Child-Pugh classification, ALB levels, and EVD (VR value) were predictive factors for rebleeding after endoscopic treatment of EV. Differences between visual EVD estimates and VR EVD measurements were large. (Kappa value: 0.391, P < .001). However, the 2 methods showed high agreement for EVD >1 cm (87/95) ConclusionEVD (VR value) can more accurately predict rebleeding rates. It can also provide a basis for selecting appropriate endoscopic treatment modalities for EV and effectively circumvent postoperative EV rebleeding.

Clinical outcomes of endoscopic detachable snare ligation for colonic diverticular hemorrhage: Multicenter cohort study.

The hemostatic mechanism of endoscopic detachable snare ligation (EDSL) for colonic diverticular hemorrhage (CDH) is similar to that of endoscopic band ligation, which is effective and safe. However, because reports on EDSL are scarce, we conducted a two-center cohort study to evaluate its effectiveness. This study analyzed 283 patients with CDH treated with EDSL at two Japanese hospitals between July 2015 and November 2021. Patient characteristics and clinical outcomes were retrospectively evaluated. A Kaplan-Meier analysis was performed to evaluate the cumulative probability of rebleeding after EDSL. A Cox proportional hazards regression analysis was performed to compare the effects of complete and incomplete ligation on rebleeding. The initial hemostasis success and early rebleeding rates were 97.9% and 11.0%, respectively. The time to hemostasis after identification of the bleeding site and total procedure time were 9 min and 44 min, respectively. Red blood cell transfusion was required for 32.9% of patients. The median hospital length of stay after EDSL was 5 days. The complete ligation rate of the early rebleeding group was significantly lower than that of the group without early rebleeding (P < 0.01). The 1-year cumulative rebleeding rate with EDSL was 28.2%. Complete ligation was associated with decreased cumulative rebleeding after EDSL (P < 0.01). One patient experienced colonic diverticulitis; however, colonic perforation was not observed. Complete ligation is associated with reduced short-term and long-term rebleeding. EDSL could be valuable for CDH because of its low rebleeding rate and the absence of serious adverse events.

Predictive value of blood coagulation and routine blood indices for rebleeding after endoscopic treatment in hepatitis B-related cirrhotic patients with esophagogastric fundal varices: a logistic regression model analysis.

To evaluate the predictive value of blood coagulation and routine blood indices for rebleeding after endoscopic treatment of ruptured esophagogastric fundal varices (EGVB) in cirrhotic patients with hepatitis B infection. This retrospective analysis included 248 patients with hepatitis B-related cirrhosis and EGVB who received initial endoscopic treatment from October 2019 to March 2022 and were followed up for 12 months. Patients were divided into rebleeding and non-rebleeding groups. Laboratory indices were analyzed, and univariate and multivariate analyses identified predictors of rebleeding. The efficacy of a logistic regression model was evaluated using Receiver Operating Characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA), and a risk factor nomogram was constructed for assessing the predictive efficiency of those risk factors. Univariate analysis showed significant differences in portal vein diameters and lower Child-Pugh scores in the rebleeding group in contrast to those in the non-rebleeding group. Key laboratory markers such as platelet count (PLT), albumin (ALB), alanine aminotransferase (ALT), lymphocytes (LYM), and prognostic nutritional index (PNI) were lower, while prothrombin time (PT) and lactate levels (LN) were higher in the rebleeding group than those in the non-rebleeding group. Multivariate analysis identified portal vein diameter, PLT, ALT, PT, LYM, and PNI as significant predictors of rebleeding. The logistic model demonstrated high accuracy (AUC=0.986) and clinical value, validated by ROC curves, calibration curves (C-index =0.986), and DCA results. A risk factor predictive nomogram was successfully constructed. This study developed a logistic regression model with a nomogram for predicting EGVB-related rebleeding in patients with hepatitis B-related cirrhosis, achieving an AUC of 0.986, indicating high accuracy and significant clinical relevance.

Aneurysmal Inflow Rate Coefficient Predicts Ultra-early Rebleeding in Ruptured Intracranial Aneurysms: Preliminary Report of a Computational Fluid Dynamics Study.

Rebleeding from a ruptured intracranial aneurysm has poor outcomes. Although numerous factors are associated with rebleeding, studies on computational fluid dynamics (CFD) on hemodynamic parameters associated with early rebleeding are scarce. In particular, no report of rebleeding in ultra-early phase exists. We aimed to elucidate the specific hemodynamic parameters associated with ultra-early rebleeding using CFD. In this study, the rebleeding group included patients with aneurysmal subarachnoid hemorrhage (aSAH) that rebled within 6 h from the onset. The control group included patients without rebleeding, observed for >10 h following the initial rupture. Clinical images after initial rupture and before rebleeding were used to build 3D vessel models for hemodynamic analysis focusing on the following parameters: time-averaged wall shear stress (WSS), normalized WSS, low shear area, oscillatory shear index, relative residence time, pressure loss coefficient, and aneurysmal inflow rate coefficient (AIRC). Five and 15 patients in the rebleeding and control groups, respectively, met the inclusion criteria. The World Federation of Neurosurgical Surgeons grade was significantly higher in the rebleeding group (p = 0.0088). Hemodynamic analysis showed significantly higher AIRC in the rebleeding group (p = 0.042). The other parameters were not significantly different between groups. There were no significant differences or correlations between SAH severity and AIRC. AIRC was identified as a hemodynamic parameter associated with ultra-early rebleeding of ruptured intracranial aneurysms. Thus, AIRC calculation may enable the prediction of ultra-early rebleeding.

Factors influencing re-bleeding after trans-arterial embolization for endoscopically unmanageable peptic ulcer bleeding

Background/Aims Acute peptic ulcer bleeding is the most common cause of non-variceal upper gastrointestinal bleeding (NVUGIB). Endoscopic hemostasis is the standard treatment. However, various conditions complicate endoscopic hemostasis. Transarterial visceral embolization (TAE) may be helpful as a rescue therapy. This study aimed to investigate the factors associated with rebleeding after TAE. Methods We retrospectively investigated the records of 156 patients treated with TAE between January 2007 and December 2021. Rebleeding was defined as the presence of melena, hematemesis, or hematochezia, with a fall (>2.0 g/dl) in hemoglobin level or shock after TAE. The primary outcomes were rebleeding rate and 30-day mortality. Results Seventy patients with peptic ulcer bleeding were selected, and rebleeding within a month after TAE occurred in 15 patients (21.4%). Among the patients included in rebleeding group, significant increases were observed in the prevalence of thrombocytopenia (73.3% vs. 16.4%, p<.001) and ulcers >1 cm (93.3% vs 54.5%, p = .014). The mean AIMS65 (albumin, international normalized ratio, mental status, systolic blood pressure, age >65 years) score (2.3 vs 1.4, p = .009) was significantly higher in the rebleeding group. Multivariate logistic analysis revealed that thrombocytopenia (odds ratio 31.92, 95% confidence interval 6.24–270.6, p<.001) and larger ulcer size (odds ratio 27.19, 95% confidence interval 3.27–677.7, p=.010) significantly increased the risk of rebleeding after TAE. Conclusion TAE was effective in the treatment of patients with high-risk peptic ulcer bleeding. AIMS65 score was a significant predictor of rebleeding after TAE, and thrombocytopenia and larger ulcer size increased the risk of rebleeding after TAE.

Sirotik Varis Kanamalarında Tekrar Kanama Belirleyicileri

Aim: Cirrhotic patients with acute variceal bleeding are characterized by a high mortality and rebleeding rate. The aim of this study was to explore predictors of rebleeding in cirrhotic patients. Methods: Cirrhotic patients who were admitted to the hospital were retrospectively analyzed. Rebleeding was defined as a new onset of hematemesis, hematochezia or melena after endoscopic therapy, and a period of stable vital signs and hemoglobin. Medical records as laboratory data include hemoglobin and platelet level, prothrombin time, creatinine, bilirubin, albumin level, vital signs, need of blood transfusions, comorbidities, medications, clinical findings as presence of ascites and hepatic encephalopathy, and endoscopic findings of varices were recorded and entered a computer-based database. Child-Pugh stage was also calculated and recorded. Results: 20 patients (21%) with recurrent hemorrhage after control of the variceal bleeding during the six-week follow-up period were included in this study. The level of albumin and hemoglobin in the rebleeding group were significantly lower than those in non-rebleeding group. The mean level of albumin was 2.45 mg/dL (vs. 3.05 mg/dL, p=0.01) and hemoglobin was 7.96 g/dL (vs. 9.92 g/dL, p=0.001). Ascites was seen to be significantly higher in the rebleeding group (50% vs. 14%, p=0.002). After multivariate regression analysis, we found that lower hemoglobin level and Child-Pugh grade were the only independent significant predictors for variceal rebleeding. Conclusion: Since factors such as the Child-Pugh grade, hypoalbuminemia and presence of ascites are associated with portal hypertension and hepatic failure, we found that lower hemoglobin level and Child-Pugh grade were the only independent significant predictors for variceal rebleeding.

Risk analysis of 30-day rebleeding in acute non-variceal upper gastrointestinal bleeding

Background and study aimsThis study aimed to compare the prognostic value of ABC, Glasgow-Blatchford, Rockall and AIMS65 scoring systems in predicting rebleeding rate within 30 days after endoscopic treatment of acute non-variceal upper gastrointestinal bleeding (ANVUGIB). Patients and methodsA total of 93 patients with ANVUGIB were selected as the study subjects and they were divided into groups according to whether there was rebleeding in the 30 days’ follow-up period. 7 patients with rebleeding within 30 days were included in the rebleeding group, and the other 86 patients without rebleeding were included in the non-rebleeding group. ResultsBy drawing ROC curve, we found that ABC scoring system had the highest accuracy (area under the receiver operating characteristic (AUROC) curve [95% confidence interval (CI), 0.65]) in predicting rebleeding within 30 days compared with the AIMS65 (0.56; P < 0.001), RS (0.51; P < 0.001), and GBS (0.61; P < 0.001). ABC scoring system showed the highest risk of rebleeding in 30 days. When the 4 scoring standards were judged as medium–high risk patients, the efficacy of the ABC scoring system in predicting the risk of rebleeding at 30 days for ANVUGIB was found to be the best in diagnostic sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy. ConclusionComprehensive evaluation showed that ABC score had the highest prediction accuracy. The negative differential significance of each evaluation method was great, that is, the risk of rebleeding was generally low when judged as low risk patients, while the value of predicting rebleeding was limited when judged as medium and high risk patients.

Risk Factors for Rebleeding After Successful Rapid Rhino Packing in Epistaxis Patients

Background and Objectives: Epistaxis is one of the most common emergencies in otolaryngology, and the recently developed Rapid Rhino nasal pack, a balloon-type nasal packing device, is widely used in emergency departments. Rebleeding after initial treatment increases patients’ discomfort and medical costs. The aim of this study was to investigate risk factors for rebleeding in patients treated with Rapid Rhino packing.Methods: In this retrospective study, 93 patients with epistaxis treated with Rapid Rhino from January 2020 to November 2022 were divided into the well-controlled group (39 patients) and the rebleeding group (54 patients), and the baseline characteristics, management methods, and complications were compared between these groups. The rebleeding group was divided according to whether patients experienced a single episode of rebleeding (38 patients) or multiple rebleeding episodes (16 patients), and the differences between these two groups were compared.Results: Oral anticoagulation therapy was associated with a higher risk of rebleeding after Rapid Rhino packing (odds ratio [OR]=8.41, p=0.047). A history of nasal surgery was associated with multiple rebleeding (OR=22.55, p=0.009). Age, sex, the management method, complications, and the site of bleeding were not found to be related to rebleeding.Conclusion: Patients with rebleeding after Rapid Rhino nasal packing had a higher rate of concurrent oral anticoagulation therapy. A history of nasal surgery was strongly associated with multiple episodes of rebleeding. A detailed medical history can be important for assessing the risk of rebleeding in epistaxis patients treated with Rapid Rhino packing.

Risk factors associated with failure of endoscopic combined treatment to prevent varices rebleeding in patients with liver cirrhosis

ABSTRACT Background The aim of this study is to investigate risk factors associated with gastroesophageal variceal rebleeding after endoscopic combined treatment. Research design and methods Patients who had liver cirrhosis and underwent endoscopic treatment to prevent variceal rebleeding were retrospectively recruited. Hepatic venous pressure gradient (HVPG) measurement and CT examination of portal vein system were performed before endoscopic treatment. Endoscopic obturation for gastric varices and ligation for esophageal varices were performed simultaneously at the first treatment. Results One hundred and sixty-five patients were enrolled, and after the first endoscopic treatment, recurrent hemorrhage occurred in 39 patients (23.6%) during 1-year follow-up. Compared to the non-rebleeding group, HVPG was significantly higher (18 mmHg vs.14 mmHg, P = 0.024) and more patients had HVPG exceeding 18 mmHg (51.3% vs.31.0%, P = 0.021) in the rebleeding group. No significant difference was found in other clinical and laboratory data between two groups (P > 0.05 for all). By a logistic regression analysis, high HVPG was the only risk factor associated with failure of endoscopic combined therapy (OR = 1.071, 95%CI, 1.005–1.141, P = 0.035). Conclusions The poor efficacy of endoscopic treatment to prevent variceal rebleeding was associated with high HVPG. Therefore, other therapeutic options should be considered for the rebleeding patients with high HVPG.

Effect of D-dimer on the prognosis of patients with aneurysmal subarachnoid hemorrhage based on propensity score matching

Objective: To evaluate the effect of D-dimer on the prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH). Methods: A total of 1 658 patients who were first diagnosed with aSAH in West China Hospital of Sichuan University from December 2013 to June 2019 were retrospectively analyzed. All patients were divided into four groups according to the median and quartiles of D-dimer level, including 415 cases, 414 cases, 414 cases, and 415 cases in groups Q1, Q2, Q3, and Q4, respectively. Groups Q2, Q3, Q4, and group Q1 were matched by propensity score matching (PSM), and the correlation between D-dimer and each outcome was analyzed by logistic regression. Since there is no general clinical classification standard for D-dimer, this study attempted to reclassify patients into groups q1 (<0.55 mg/L, 94 cases), q2 (0.55-1.65 mg/L, 435 cases), q3 (1.65-5.50 mg/L, 650 cases) and q4 (>5.50 mg/L, 303 cases) based on 1, 3, 5, 10 times of the upper limit of the current clinical reference value. Results: The age of 1 658 aSAH patients were (57±12) years, including 1 068 males and 590 females. After PSM based on the median and quartiles of D-dimer level, there were 318 cases, 318 cases, 251 cases, and 229 cases in groups Q1, Q2, Q3, and Q4, respectively. Compared with group Q1 (<1.23 mg/L), the risk of in-hospital infection (OR=2.14, 95%CI: 1.47-3.11, P<0.001), pneumonia (OR=2.22, 95%CI: 1.51-3.28, P<0.001), urinary tract infection (OR=1.75, 95%CI: 1.12-2.75, P=0.014) and intracranial rebleeding (OR=3.59, 95%CI: 1.30-9.91, P=0.013) group Q4 (>4.95 mg/L) was higher. Likewise, the risk of adverse outcomes in group Q4 was also higher than that in group Q1, including unfavorable outcome at discharge (OR=2.12, 95%CI: 1.43-3.14, P<0.001), mortality during hospitalization (OR=3.03, 95%CI: 1.26-7.33, P=0.014), mortality within 90 days (OR=2.33, 95%CI:1.29-4.22, P=0.005), mortality within 180 days (OR=1.92, 95%CI: 1.12-3.29, P=0.018), mortality within 1 year (OR=2.07, 95%CI:1.23-3.47, P=0.006) and mortality during the longest follow-up period (OR=1.97, 95%CI:1.26-3.09, P=0.003). After secondary grouping and PSM based on current clinical reference values, there were 90 cases, 87 cases, 90 cases, and 43 cases, respectively in groups q1, q2, q3 and q4. The risk of nosocomial infection (OR=2.26, 95%CI: 1.14-4.45, P=0.019), blood-borne infection (OR=8.86, 95%CI:1.08-72.78, P=0.042), poor prognosis at discharge (OR=4.92, 95%CI: 2.18-11.07, P<0.001), death within 180 days (OR=3.39, 95%CI: 1.04-11.08, P=0.043), death within 1 year (OR=3.23, 95%CI: 1.10-9.49, P=0.033), and death within the longest follow-up period (OR=3.28, 95%CI: 1.34-8.01, P=0.009) was still higher in group q4 than that in group q1. Conclusion: aSAH patients with high D-dimer level have a higher risk of complications and mortality during hospitalization and worse clinical prognosis.

Associations Between Endoscopic Primary Prophylaxis and Rebleeding in Liver Cirrhosis Patients with Esophagogastric Variceal Bleeding.

AimTo identify the association between endoscopic primary prophylaxis and the risk of rebleeding in patients with liver cirrhosis receiving endoscopic therapy.MethodsThis cohort study involved in 944 liver cirrhosis patients with esophagogastric variceal bleeding (EGVB) receiving endoscopic therapy. All participants were divided into two groups: rebleeding group (n = 425) and non-rebleeding group (n = 519) according to the occurrence of rebleeding in patients. Rebleeding indicated any bleeding after endoscopic therapy for the first bleeding of esophagogastric varices in liver cirrhosis patients. Univariate and multivariate logistic analyses were employed to identify the association between endoscopic primary prophylaxis and rebleeding in patients with liver cirrhosis after endoscopic therapy.ResultsIn total, 425 patients rebleeded at the end of the follow-up. The risk of rebleeding in patients with endoscopic primary prophylaxis decreased by 0.773 times (OR = 0.227, 95%CI: 0.139–0.372, P < 0.001) after adjusting covariables. Subgroups were divided according to the Child-Pugh (CP) score, and the results revealed that the risk of rebleeding in patients with endoscopic primary prophylaxis decreased by 0.858 times in Grade A patients (OR = 0.142, 95%CI: 0.066–0.304, P < 0.001) and 0.804 times in Grade B patients (OR = 0.196, 95%CI: 0.085–0.451, P < 0.001) compared with patients without endoscopic primary prophylaxis, but showed no difference in Grade C patients.ConclusionEndoscopic primary prophylaxis was associated with a decreased risk of rebleeding in liver cirrhosis patients with EGVB after endoscopic therapy, which suggested that clinicians should pay more attention to endoscopic primary prophylaxis to prevent the occurrence of rebleeding in these patients.

Establishment of a risk prediction model for acute upper gastrointestinal rebleeding in elderly patients

To establish a prediction model of acute upper gastrointestinal rebleeding (AUGIRB) for elderly patients by combining and applying multiple indicators. A retrospective observational study was conducted. The clinical data of 161 elderly patients (age ≥ 65 years old) who suffered from acute upper gastrointestinal bleeding (AUGIB) and who were hospitalized in Shanghai General Hospital from July 2018 to December 2020 were recorded. The patients were divided into the rebleeding group (31 cases) and the non-rebleeding group (130 cases) according to whether gastrointestinal rebleeding occurred. Univariate analysis was adopted to screen AUGIRB-related risk factors and Logistic regression analysis was used to screen independent predictors of AUGIRB so that a predictive model was constructed. Based on the area under the curve (AUC) of the receiver operator characteristic curve (ROC curve), the predictive ability of the prediction model for AUGIRB was evaluated, the optimal cut-off value was determined, and the odds ratio (OR) and its 95% confidence interval (95%CI) were calculated. Bootstrap resampling technology was used to validate the predictive ability of the model. Univariate Logistic analysis showed that oral anticoagulant drugs, oral antiplatelet drugs, albumin (ALB), platelet count (PLT), Glasgow-Blatchford bleeding score (GBS), D-dimer, fibrinogen (FIB), and international normalized ratio (INR) all had a significant effect on the occurrence of AUGIRB among elderly patients. Multivariate Logistic regression analysis showed that the oral antiplatelet drugs (OR = 11.150, 95%CI was 1.888-65.852, P < 0.05) and GBS score (OR = 2.503, 95%CI was 1.523-4.114, P < 0.05) were the independent risk factors of AUGIRB among elderly patients, while the ALB (OR = 0.764, 95%CI was 0.626-0.932, P < 0.05) and FIB (OR = 0.065, 95%CI was 0.011-0.370, P < 0.05) were the protective factors of AUGIRB among elderly patients. The AUC of the above four indexes joint prediction model was 0.979. The verification results of the model showed that the consistency index (C-index) of the model was 0.986. The prediction model fitted in this research has a high prediction accuracy and it also has a certain reference value for the judgment of elderly patients who suffer from AUGIRB.

Rebleeding and prognosis of patients with liver cirrhosis and severe esophagogastric variceal bleeding

Objective To investigate the risk factors for rebleeding within 5 years and the influencing factors for 5-year survival in patients with liver cirrhosis and severe esophagogastric variceal bleeding (EVB). Methods A retrospective analysis was performed for 129 patients with liver cirrhosis who attended Tianjin Third Central Hospital from May 2012 to May 2014 due to severe EVB for the first time, with a follow-up time of 5 years. Related clinical data were analyzed, including age, sex, cause of liver cirrhosis, presence or absence of infection at the first time of bleeding, liver stiffness measurement (LSM), splenic stiffness measurement (SSM), portal vein diameter, biochemical parameters, rebleeding time, and prognosis. Esophagogastric variceal rebleeding was defined as the primary endpoint and death was defined as the secondary endpoint. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the independent risk factors for rebleeding, and a Cox regression analysis was used to analyze the predictive indicators for 5-year survival in EVB patients; the Kaplan-Meier curve was used to analyze the cumulative non-rebleeding rate. Results Among the 129 patients, 87(67.4%) experienced rebleeding during follow-up. There were significant differences between the rebleeding group and the non-rebleeding group in the proportion of patients with alcoholic cirrhosis (χ2=4.896, P=0.027), portal vein diameter (t=2.203, P=0.030), LSM(Z=-2.771, P=0.006), and SSM(t=2.678, P=0.010). The patients with alcoholic cirrhosis had a significantly higher mean number of times of bleeding than those with non-alcoholic cirrhosis (all P Conclusion Alcoholic cirrhosis, LSM, and SSM are independent risk factors for rebleeding within 5 years in EVB patients, and age, times of bleeding, portal vein diameter, and presence or absence of infection at the first time of bleeding are associated with 5-year survival.

Risk factors for early rebleeding after endoscopic therapy for esophageal varices in cirrhotic patients

Objective To investigate the risk factors for early rebleeding after endoscopic ligation or sclerotherapy for esophageal variceal bleeding in cirrhotic patients. Methods A retrospective analysis was performed for the clinical data of 153 cirrhotic patients with esophageal variceal bleeding who underwent endoscopic ligation or sclerotherapy in Beijing YouAn Hospital, Capital Medical University, from May 2017 to May 2019, and according to the presence or absence of rebleeding from 72 hours to 6 weeks after endoscopic therapy, the patients were divided into rebleeding group and non-rebleeding group. A logistic regression analysis was performed to investigate independent risk factors for early rebleeding. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Results Early rebleeding rate was 24.8% (38/153). Compared with the non-rebleeding group, the rebleeding group had a significantly lower albumin (Alb) and significantly higher activated partial thromboplastin time and prothrombin time (all P Conclusion Portal vein thrombosis, massive ascites, Child-Pugh C liver cirrhosis, and hypoproteinemia are independent risk factors for early rebleeding after endoscopic therapy in cirrhotic patients with esophageal variceal bleeding, which should be taken seriously in clinical practice.

Efficacy of Endoscopic Variceal Ligation in the Control of Variceal Bleeding: A Real World Setting

Background: Combined pharmacological and endoscopic therapy, particularly endoscopic variceal ligation (EVL), is the first-line treatment for acute esophageal variceal bleeding (EVB). In patients with rebleeding, the rescue treatment with a transjugular intrahepatic portosystemic shunt (TIPS) is recommended. However, in a real world setting where the accessibility to TIPS is limited, repeated endoscopic therapy is inevitably performed. Objective: To study the outcomes of EVL on rebleeding and mortality in the resource-limited setting. Materials and Methods: Patients who underwent EVL during 2017 to 2018 are included. Patients were treated with vasoactive drugs and EVL until the eradication of varices. We focus on the outcome of a second attempt at EVL to control EVB. The rebleeding and mortality rate within 6 months after the combined treatment were collected. Logistic regression analysis was performed to identify risk factors of rebleeding. Results: There were 339 EVL performed during the 2-year period. Of these procedures, EVL was indicated to control acute EVB in 118 patients. EVB in 98 patients (83%) were successfully controlled in only one session of EVL, while those of 20 patients (17%) required at least 2 sessions to control the recurrent EVB. In the rebleeding group, no patient rebled within 5 days after the first EVL, while 15 patients (75%) rebled within 6 weeks. Once rebled, the second EVL was performed. There were 5 patients (25%) whom the second EVL failed to control the recurrent EVB. Those recurrent EVB were finally controlled by the other endoscopic therapy. The 6-week mortality after rebleeding was 15%. Hepatocellular carcinoma and creatinine are factors associated with recurrent EVB within 6 weeks with odds ratio (OR) 5.96 (95% CI 1.41 to 25.19, p = 0.02) and OR 1.47 (95% CI: 1.02 to 2.11, p = 0.04), respectively. Conclusion: The second attempt at endoscopic therapy can be considered to control recurrent EVB after the first EVL with a success rate of 75% in area where an accessibility to a treatment with TIPS is limited.

Admission Neutrophil–Lymphocyte Ratio Predicts Rebleeding Following Aneurismal Subarachnoid Hemorrhage

The relationship between neutrophil-lymphocyte ratio (NLR) and the occurrence of rebleeding in aneurysmal subarachnoid hemorrhage (aSAH) is poorly understood. Our study aimed to investigate the association between NLR on admission and rebleeding following aSAH. Clinical and laboratorial data from patients with aSAH were retrospectively collected, including leukocyte, neutrophil, lymphocyte, and NLR. Univariate and multivariate analyses were performed to assess for the association of NLR with rebleeding. We performed propensity-score matching analyses to correct imbalances in patient characteristics between the rebleeding group and nonrebleeding group. Rebleeding occurred in 30 of 716 (4.19%) patients with aSAH in this cohort. Patients with rebleeding had significantly higher NLR comparing with patients without rebleeding (11.27 vs. 5.5; P < 0.05) in the univariate analysis. In the multivariate analysis, NLR was considered as a risk factor of rebleeding (odds ratio, 0.283; 95% confidence interval, 0.130-0.620; P= 0.002), as well as Fisher grade (odds ratio, 0.353, 95% confidence interval, 0.151-0.824; P= 0.016). The area under the curve of the NLR and combined NLR-Fisher grade model was 0.702 and 0.744 (sensitivity was 39.94%, and specificity was 100%) for predicting rebleeding, respectively. After propensity-score matching, the optimal cutoff value for NLR as a predictor for rebleeding following aSAH was determined as 5.4 (sensitivity was 83.33%, and the specificity was 63.33%). Higher NLR predicts the occurrence of rebleeding and poor outcome, and NLR combined with Fisher grade significantly improves the prediction of rebleeding following aSAH.

Analysis of core indicators of fatal gastrointestinal rebleeding in emergency from the perspective of big data

To explore a method of screening the core indicators in the emergency database that can be used to evaluate the in-hospital fatal gastrointestinal rebleeding by using the big data algorithm. Based on the emergency database of the Chinese PLA General Hospital, through the big data retrieval technology, all the 647 patients diagnosed as gastrointestinal bleeding in the emergency database were enrolled, except those who were admitted to the hospital for the first time and whose hemoglobin (Hb) was less than 90 g/L or did not undergo Hb test. Among them, there were 313 in the rebleeding group (fatal rebleeding in the hospital) and 334 in the non-rebleeding group (no fatal rebleeding in the hospital). General data of patients were collected, including gender, age, physical signs, blood gas, test index collection data, and the identification of gastrointestinal rebleeding. The fusion algorithm of rough set algorithm, genetic algorithm, and cellular automaton algorithm were used to calculate the key indicators that affect gastrointestinal rebleeding. A total of 499 indicators were calculated by machine fusion algorithm, after screening 5 times repeatedly, 24 key indicators were screened out, 3 of which were vital signs, including systolic blood pressure (SBP), diastolic blood pressure (DBP), temperature (T); 7 key indicators of blood routine, including white blood cell count (WBC), eosinophil (EOS), monocyte (MONO), Hb, hematocrit (HCT), red cell distribution width (RDW), mean corpuscular hemoglobin (MCH); 3 key indicators of coagulation, including prothrombin time (PT), plasma fibrinogen (FIB), activated partial thromboplastin time (APTT); 5 key indicators of biochemical, including myoglobin (MYO), chloride, glucose (GLU), serum albumin (ALB), total bilirubin (TBil); and 6 key indicators of blood gas, including pH, lactate (Lac), oxygen saturation (SO2), base excess (BE), bicarbonate (HCO3-), partial pressure of carbon dioxide (PaCO2). Using big data technology, 24 core indicators for evaluating the fatal gastrointestinal rebleeding in hospitals can be screened out from the emergency database, providing new ideas and methods for clinical diagnosis of the disease.

Monitoring of intracranial pressure in patients with hypertensive intracerebral hemorrhage after minimally invasive surgery and its correlation with nerve injury, inflammatory stress response

Objective To monitor the intracranial pressure in patients with hypertensive intracerebral hemorrhage after minimally invasive surgery and to explore its correlation with nerve injury, inflammatory stress response. Methods From December 2014 to October 2017, 60 patients of hypertensive intracerebral hemorrhage underwent minimally invasive surgery in Taizhou Municipal Hospital were chosen in the research.According to the prognosis, the patients were divided into hematoma clearance group (n=45) and rebleeding group(n=15). The levels of intracranial pressure 24h after surgery, serum contents of nerve injury related indicators, inflammatory mediators and oxidative stress indicators were compared between the two groups.Pearson test was used to evaluate the correlation between intracranial pressure 24h after surgery and nerve injury, inflammatory stress response. Results 24 h after surgery, the intracranial pressure in the hematoma clearance group was (349.27±45.81)mmH2O, which was lower than (511.09±57.64)mmH2O in the rebleeding group (t=-11.093, P<0.05). The serum contents of nerve injury markers such as NSE, h-FABP, GFAP, S100B in the hematoma clearance group were (9.37±1.05)ng/L, (7.04±0.85)μg/L, (7.19±0.85)μg/L, (20.47±3.19)ng/L, respectively, which were significantly lower than those in the rebleeding group [(14.58±1.62)ng/L, (11.36±1.62)μg/L, (16.23±1.72)μg/L, (45.87±5.62)ng/L](t=-14.414, -13.330, -26.989, -21.749, all P<0.05), the BNP level of the hematoma clearance group [(22.61±2.85)μg/L] was significantly higher than (15.28±1.79)μg/L in the rebleeding group (t=11.732, P<0.05). The levels of inflammatory mediators such as IL-6, IL-1β, TNF-α in the hematoma clearance group were (5.28±0.59)ng/L, (9.73±1.54)ng/L, (15.28±1.76)ng/L, respectively, which were lower than those in the rebleeding group [(11.07±1.63)ng/L, (20.46±2.95)ng/L, (23.51±3.79)ng/L] (t=-20.410, -18.225, -11.445, all P<0.05). The levels of antioxidant factors such as SOD, CAT in the hematoma clearance group were (49.58±6.21)U/L, (68.11±7.59)U/L, respectively, which were significantly higher than those in the rebleeding group [(32.16±4.05)U/L, (45.23±5.61)U/L] (t=10.138, 10.715, all P<0.05). The contents of ROS, AOPP in the hematoma clearance group were (15.28±1.73)μg/L, (10.94±1.62)μg/L, respectively, which were lower than those in the rebleeding group [(34.19±4.25)μg/L, (22.53±2.18)μg/L](t=-24.632, -21.945, all P<0.05). Pearson test showed that the level in 24h intracranial pressure in patients with hypertensive intracerebral hemorrhage was positively correlated with the degree of nerve injury, inflammation stress(r=0.371, 0.483, 0.427, 0.519, 0.537, all P<0.05). Conclusion Monitoring of intracranial pressure after minimally invasive surgery for hypertensive intracerebral hemorrhage, can effectively judge the severity of nerve injury and inflammatory stress reaction, and can predict the risk of recurrent intracerebral hemorrhage.
