The main aim of this opinion review is to comment on the recent article published by Garg et al in the World Journal of Gastroenterology 2023;29:4593–4603.The authors in the published article developed a new scoring system,Garg incon-tinence scores(GIS),for fecal incontinence(FI).FI is a chronic debilitating disease that has a severe negative impact on the quality of life of the patients.Rome IV criteria define FI as multiple episodes of solid or liquid stool passed into the clothes at least twice a month.The associated social stigmatization often leads to significant under-reporting of the condition,which further impairs management.An important point is that the complexity and vagueness of the disease make it difficult for the patients to properly define and report the magnitude of the problem to their physicians.Due to this,the management becomes even more difficult.This issue is resolved up to a considerable extent by a scoring ques-tionnaire.There were several scoring systems in use for the last three decades.The prominent of them were the Cleveland Clinic scoring system or the Wexner scoring system,St.Marks Hospital or Vaizey’s scores,and the FI severity index.However,there were several shortcomings in these scoring systems.In the opinion review,we tried to analyze the strength of GIS and compare it to the existing scoring systems.The main pitfalls in the existing scoring systems were that most of them gave equal weightage to different types of FI(solid,liquid,flatus,etc.),were not comprehensive,and took only the surgeon’s perception of FI into view.In GIS,almost all shortcomings of previous scoring systems had been addressed:different weights were assigned to different types of FI by a robust statistical methodology;the scoring system was made comprehensive by including all types of FI that were previously omitted(urge,stress and mucus FI)and gave priority to patients’rather than the physicians’perceptions while developing the scoring system.Due to this,GIS indeed looked like a paradigm shift in the evaluation of FI.However,it is too early to conclude this,as GIS needs to be validated for accuracy and simplicity in future studies. 展开更多

As a key node of modern transportation network,the informationization management of road tunnels is crucial to ensure the operation safety and traffic efficiency.However,the existing tunnel vehicle modeling methods generally have problems such as insufficient 3D scene description capability and low dynamic update efficiency,which are difficult to meet the demand of real-time accurate management.For this reason,this paper proposes a vehicle twin modeling method for road tunnels.This approach starts from the actual management needs,and supports multi-level dynamic modeling from vehicle type,size to color by constructing a vehicle model library that can be flexibly invoked;at the same time,semantic constraint rules with geometric layout,behavioral attributes,and spatial relationships are designed to ensure that the virtual model matches with the real model with a high degree of similarity;ultimately,the prototype system is constructed and the case region is selected for the case study,and the dynamic vehicle status in the tunnel is realized by integrating real-time monitoring data with semantic constraints for precise virtual-real mapping.Finally,the prototype system is constructed and case experiments are conducted in selected case areas,which are combined with real-time monitoring data to realize dynamic updating and three-dimensional visualization of vehicle states in tunnels.The experiments show that the proposed method can run smoothly with an average rendering efficiency of 17.70 ms while guaranteeing the modeling accuracy(composite similarity of 0.867),which significantly improves the real-time and intuitive tunnel management.The research results provide reliable technical support for intelligent operation and emergency response of road tunnels,and offer new ideas for digital twin modeling of complex scenes. 展开更多

BACKGROUND Emphysematous pyelonephritis(EPN)is a life-threatening necrotizing renal parenchyma infection characterized by gas formation due to severe bacterial infection,predominantly affecting diabetic and immunocompromised patients.It carries high morbidity and mortality,requiring early diagnosis and timely intervention.Various prognostic scoring systems help in triaging critically ill patients.The National Early Warning Score 2(NEWS 2)scoring system is a widely used physiological assessment tool that evaluates clinical deterioration based on vital parameters,but its standard form lacks specificity for risk stratification in EPN,necessitating modifications to improve treatment decisionmaking and prognostic accuracy in this critical condition.AIM To highlight the need to modify the NEWS 2 score to enable more intense monitoring and better treatment outcomes.METHODS This prospective study was done on all EPN patients admitted to our hospital over the past 12 years.A weighted average risk-stratification index was calculated for each of the three groups,mortality risk was calculated for each of the NEWS 2 scores,and the need for intervention for each of the three groups was calculated.The NEWS 2 score was subsequently modified with 0-6,7-14 and 15-20 scores included in groups 1,2 and 3,respectively.RESULTS A total of 171 patients with EPN were included in the study,with a predominant association with diabetes(90.6%)and a female-to-male ratio of 1.5:1.The combined prognostic scoring of the three groups was 10.7,13.0,and 21.9,respectively(P<0.01).All patients managed conservatively belonged to group 1(P<0.01).Eight patients underwent early nephrectomy,with six from group 3(P<0.01).Overall mortality was 8(4.7%),with seven from group 3(87.5%).The cutoff NEWS 2 score for mortality was identified to be 15,with a sensitivity of 87.5%,specificity of 96.9%,and an overall accuracy rate of 96.5%.The area under the curve to predict mortality based on the NEWS 2 score was 0.98,with a confidence interval of(0.97,1.0)and P<0.001.CONCLUSION Modified NEWS 2(mNEWS 2)score dramatically aids in the appropriate assessment of treatment-related outcomes.MNEWS 2 scores should become the practice standard to reduce the morbidity and mortality associated with this dreaded illness. 展开更多

BACKGROUND Chronic liver disease is a growing global health problem,leading to hepatic decompensation characterized by an array of clinical and biochemical complic-ations.Several scoring systems have been introduced in assessing the severity of hepatic decompensation with the most frequent ones are Child-Pugh score,model of end-stage liver disease(MELD)score,and MELD-Na score.Anemia is frequently observed in cirrhotic patients and is linked to worsened clinical outcomes.Although studies have explored anemia in liver disease,few have investigated the correlation of hemoglobin level with the severity of hepatic decompensation.AIM To determine the relationship between hemoglobin levels and the severity of decompensated liver disease and comparing the strength of this correlation using the Child-Pugh,MELD,and MELD-Na scores.METHODS This cross-sectional study was conducted at a tertiary care hospital with 652 decompensated liver disease patients enrolled in the study.Data was collected on demographics,clinical history,and laboratory findings,including hemoglobin levels,bilirubin,albumin,prothrombin time(international normalized ratio),sodium,and creatinine.The Child-Pugh,MELD,and MELD-Na scores were calculated.Statistical analysis was performed using Statistical Package for the Social Sciences version 26,and correlations between hemoglobin levels and severity scores were assessed using Spearman's correlation coefficient.RESULTS The study included 405 males(62.1%)and 247 females(37.9%)with an average age of 58.8 years.Significant inverse correlations were found between hemoglobin levels and Child-Pugh,MELD,and MELD-Na scores(P<0.01),with the MELD scoring system being the strongest correlator among all.One-way analysis of variance revealed significant differences in hemoglobin levels across the severity groups of each scoring system(P=0.001).Tukey's post hoc analysis confirmed significant internal differences among each severity group.CONCLUSION Understanding the correlation between hemoglobin and liver disease severity can improve patient management by offering insights into prognosis and guiding treatment decisions. 展开更多

BACKGROUND The degree of obstruction plays an important role in decision-making for obstructive colorectal cancer(OCRC).The existing assessment still relies on the colorectal obstruction scoring system(CROSS)which is based on a comprehensive analysis of patients’complaints and eating conditions.The data collection relies on subjective descriptions and lacks objective parameters.Therefore,a scoring system for the evaluation of computed tomography-based obstructive degree(CTOD)is urgently required for OCRC.AIM To explore the relationship between CTOD and CROSS and to determine whether CTOD could affect the short-term and long-term prognosis.METHODS Of 173 patients were enrolled.CTOD was obtained using k-means,the ratio of proximal to distal obstruction,and the proportion of nonparenchymal areas at the site of obstruction.CTOD was integrated with the CROSS to analyze the effect of emergency intervention on complications.Short-term and long-term outcomes were compared between the groups.RESULTS CTOD severe obstruction(CTOD grade 3)was an independent risk factor[odds ratio(OR)=3.390,95%confidence interval(CI):1.340-8.570,P=0.010]via multivariate analysis of short-term outcomes,while CROSS grade was not.In the CTOD-CROSS grade system,for the non-severe obstructive(CTOD 1-2 to CROSS 1-4)group,the complication rate of emergency interventions was significantly higher than that of non-emergency interventions(71.4%vs 41.8%,P=0.040).The postoperative pneumonia rate was higher in the emergency intervention group than in the non-severe obstructive group(35.7%vs 8.9%,P=0.020).However,CTOD grade was not an independent risk factor of overall survival and progression-free survival.CONCLUSION CTOD was useful in preoperative decision-making to avoid unnecessary emergency interventions and complications. 展开更多

Shen et al’s retrospective study aims to compare the utility of two separate scoring systems for predicting mortality attributable to gastrointestinal(GI)injury in critically ill patients[the GI Dysfunction Score(GIDS)and the Acute Gastroin-testinal Injury(AGI)grade].The authors note that this study is the first proposal that suggests an equivalence between the ability of both scores to predict mor-tality at 28 days from intensive care unit(ICU)admission.Shen et al retrospec-tively analysed an ICU cohort of patients utilising two physicians administering both the AGI grade and GIDS score,using electronic healthcare records and ICU flowsheets.Where these physicians disagreed about the scores,the final decision as to the scores was made by an associate chief physician,or chief physician.We note that the primary reason for the development of GIDS was to create a clear score for GI dysfunction,with minimal subjectivity or inter-operator variability.The subjectivity inherent to the older AGI grading system is what ultimately led to the development of GIDS in 2021.By ensuring consensus between physicians administering the AGI,Shen et al have controlled for one of this grading systems biggest issues.We have concerns,however,that this does not represent the real-world challenges associated with applying the AGI compared to the newer GIDS,and wonder if this arbitration process had not been instituted,would the two scoring systems remain equivalent in terms of predicted mortality? 展开更多

Accurate prediction of landslide displacement is crucial for effective early warning of landslide disasters.While most existing prediction methods focus on time-series forecasting for individual monitoring points,there is limited research on the spatiotemporal characteristics of landslide deformation.This paper proposes a novel Multi-Relation Spatiotemporal Graph Residual Network with Multi-Level Feature Attention(MFA-MRSTGRN)that effectively improves the prediction performance of landslide displacement through spatiotemporal fusion.This model integrates internal seepage factors as data feature enhancements with external triggering factors,allowing for accurate capture of the complex spatiotemporal characteristics of landslide displacement and the construction of a multi-source heterogeneous dataset.The MFA-MRSTGRN model incorporates dynamic graph theory and four key modules:multilevel feature attention,temporal-residual decomposition,spatial multi-relational graph convolution,and spatiotemporal fusion prediction.This comprehensive approach enables the efficient analyses of multi-source heterogeneous datasets,facilitating adaptive exploration of the evolving multi-relational,multi-dimensional spatiotemporal complexities in landslides.When applying this model to predict the displacement of the Liangshuijing landslide,we demonstrate that the MFA-MRSTGRN model surpasses traditional models,such as random forest(RF),long short-term memory(LSTM),and spatial temporal graph convolutional networks(ST-GCN)models in terms of various evaluation metrics including mean absolute error(MAE=1.27 mm),root mean square error(RMSE=1.49 mm),mean absolute percentage error(MAPE=0.026),and R-squared(R^(2)=0.88).Furthermore,feature ablation experiments indicate that incorporating internal seepage factors improves the predictive performance of landslide displacement models.This research provides an advanced and reliable method for landslide displacement prediction. 展开更多

Objective:Neuroblastoma is the most common extracranial solid tumor in children and has complex genetic underpinnings.Previous genome-wide association studies(GWASs)have identified many loci associated with neuroblastoma susceptibility;however,their application in risk prediction for Chinese children has not been systematically explored.This study seeks to enhance neuroblastoma risk prediction by validating these loci and evaluating their performance in polygenic risk models.Methods:We validated 35 GWAS-identified neuroblastoma susceptibility loci in a cohort of Chinese children,consisting of 402 neuroblastoma patients and 473 healthy controls.Genotyping these polymorphisms was conducted via the TaqMan method.Univariable and multivariable logistic regression analyses revealed the genetic loci significantly associated with neuroblastoma risk.We constructed polygenic risk models by combining these loci and assessed their predictive performance via area under the curve(AUC)analysis.We also established a polygenic risk scoring(PRS)model for risk prediction by adopting the PLINK method.Results:Fourteen loci,including ten protective polymorphisms from CASC15,BARD1,LMO1,HSD17B12,and HACE1,and four risk variants from BARD1,RSRC1,CPZ and MMP20 were significantly associated with neuroblastoma risk.Compared with single-gene model,the 8-gene model(AUC=0.72)and 13-gene model(AUC=0.73)demonstrated superior predictive performance.Additionally,a PRS incorporating six significant loci achieved an AUC of 0.66,effectively stratifying individuals into distinct risk categories regarding neuroblastoma susceptibility.A higher PRS was significantly associated with advanced International Neuroblastoma Staging System(INSS)stages,suggesting its potential for clinical risk stratification.Conclusions:Our findings validate multiple loci as neuroblastoma risk factors in Chinese children and demonstrate the utility of polygenic risk models,particularly the PRS,in improving risk prediction.These results suggest that integrating multiple genetic variants into a PRS can enhance neuroblastoma risk stratification and potentially improve early diagnosis by guiding targeted screening programs for high-risk children. 展开更多

Background Biomarkers-based prediction of long-term risk of acute coronary syndrome(ACS)is scarce.We aim to develop a risk score integrating clinical routine information(C)and plasma biomarkers(B)for predicting long-term risk of ACS patients.Methods We included 2729 ACS patients from the OCEA(Observation of cardiovascular events in ACS patients).The earlier admitted 1910 patients were enrolled as development cohort;and the subsequently admitted 819 subjects were treated as valida-tion cohort.We investigated 10-year risk of cardiovascular(CV)death,myocardial infarction(MI)and all cause death in these pa-tients.Potential variables contributing to risk of clinical events were assessed using Cox regression models and a score was de-rived using main part of these variables.Results During 16,110 person-years of follow-up,there were 238 CV death/MI in the development cohort.The 7 most import-ant predictors including in the final model were NT-proBNP,D-dimer,GDF-15,peripheral artery disease(PAD),Fibrinogen,ST-segment elevated MI(STEMI),left ventricular ejection fraction(LVEF),termed as CB-ACS score.C-index of the score for predica-tion of cardiovascular events was 0.79(95%CI:0.76-0.82)in development cohort and 0.77(95%CI:0.76-0.78)in the validation co-hort(5832 person-years of follow-up),which outperformed GRACE 2.0 and ABC-ACS risk score.The CB-ACS score was also well calibrated in development and validation cohort(Greenwood-Nam-D’Agostino:P=0.70 and P=0.07,respectively).Conclusions CB-ACS risk score provides a useful tool for long-term prediction of CV events in patients with ACS.This model outperforms GRACE 2.0 and ABC-ACS ischemic risk score. 展开更多

BACKGROUND The rising global prevalence of gastroesophageal reflux disease(GERD)has been closely linked to lifestyle changes driven by globalization.GERD imposes a substantial public health burden,affecting quality of life and leading to potential complications.Early intervention through lifestyle modification can prevent disease onset;however,there is a lack of effective risk prediction models that emphasize primary prevention.AIM To develop and validate a GERD Risk Scoring System(GRSS)aimed at identifying high-risk individuals and promoting primary prevention strategies.METHODS A 45-item questionnaire encompassing major lifestyle and demographic risk factors was developed and validated.It was administered to healthy controls and GERD patients.Two regression models-one using continuous variables and another using categorized variables-were used to develop a computational prediction equation and a clinically applicable scoring scale.An independent validation cohort of 355 participants was used to assess model performance in terms of discrimination(C-index),calibration,sensitivity,specificity,internal consistency(Cronbach's alpha),and test-retest reliability(intraclass correlation coefficient,Bland-Altman analysis).RESULTS Significant associations were observed between GERD and key lifestyle factors.The derived GRSS equation and scoring scale demonstrated strong discriminative ability,with high sensitivity and specificity.The scoring system exhibited excellent internal consistency(Cronbach’s alpha)and strong test-retest reliability.The C-index indicated excellent predictive accuracy in both derivation and validation cohorts.CONCLUSION GRSS offers a novel and validated approach to GERD risk prediction,combining a robust equation for digital applications and a practical scale for clinical use.Its ability to accurately identify at-risk individuals supports a paradigm shift toward primary prevention,underscoring its significance in addressing the growing burden of GERD at the population level. 展开更多

As we look ahead to future lunar exploration missions, such as crewed lunar exploration and establishing lunar scientific research stations, the lunar rovers will need to cover vast distances. These distances could range from kilometers to tens of kilometers, and even hundreds and thousands of kilometers. Therefore, it is crucial to develop effective long-range path planning for lunar rovers to meet the demands of lunar patrol exploration. This paper presents a hierarchical map model path planning method that utilizes the existing high-resolution images, digital elevation models and mineral abundance maps. The objective is to address the issue of the construction of lunar rover travel costs in the absence of large-scale, high-resolution digital elevation models. This method models the reference and semantic layers using the middle- and low-resolution remote sensing data. The multi-scale obstacles on the lunar surface are extracted by combining the deep learning algorithm on the high-resolution image, and the obstacle avoidance layer is modeled. A two-stage exploratory path planning decision is employed for long-distance driving path planning on a global–local scale. The proposed method analyzes the long-distance accessibility of various areas of scientific significance, such as Rima Bode. A high-precision digital elevation model is created using stereo images to validate the method. Based on the findings, it can be observed that the entire route spans a distance of 930.32 km. The route demonstrates an impressive ability to avoid meter-level impact craters and linear structures while maintaining an average slope of less than 8°. This paper explores scientific research by traversing at least seven basalt units, uncovering the secrets of lunar volcanic activities, and establishing ‘golden spike’ reference points for lunar stratigraphy. The final result of path planning can serve as a valuable reference for the design, mission demonstration, and subsequent project implementation of the new manned lunar rover. 展开更多

Background:Acute cholangitis is an infection due to the bile duct obstruction.Despite progress in treat-ment,acute cholangitis remains potentially fatal.Early diagnosis and treatment improve the patient out-comes.The present study aimed to identify clinical and biological factors at admission associated with 30-day mortality in acute cholangitis,to build an efficient prognostic score based on these parameters and to study the performances of this new score.Methods:We enrolled all adult patients consecutively hospitalized for acute cholangitis between January 2017 and December 2021.We developed a score system named ProChol using variables significantly asso-ciated with 30-day mortality in multivariate logistic analysis and simplified this system(named sProChol)based on a simple points-based approach.Results:In total,528 patients were included,with an average age of 77±13 years,a male predominance(54.2%)and a majority of lithiasis etiology(66.5%).Mortality in 30 days was 11.9%.In multivariate logis-tic analysis,tumor etiology[adjusted odds ratio(aOR)=15.43,95%confidence interval(CI):5.90-40.40],stent obstruction(aOR=5.12,95%CI:2.02-12.99),hypoalbuminemia(aOR=3.50,95%CI:1.25-9.81),renal failure(aOR=6.51,95%CI:2.62-16.18),oxygen therapy(aOR=4.63,95%CI:1.02-20.92)and cu-rative anticoagulation(aOR=2.60,95%CI:1.23-5.52)were independently associated with the 30-day mortality while fever was a protective factor(aOR=0.37,95%CI:0.16-0.84).ProChol score using these 7 parameters and sProChol using the 3 robust factors(etiology,renal failure and anticoagulation)presented respectively an area under receiver operating characteristic(ROC)curves(AUC)of 0.81 and 0.77,higher than Tokyo(AUC=0.72)and Gravito-Soares et al.score(AUC=0.71).Patients with sProChol≥4 had a significantly higher risk of transfer to intensive care unit(13.3%vs.5.1%;P<0.001)and longer length of stay(P=0.0006).Conclusions:ProChol and sProChol constructed from simple clinico-biological parameters at admission,present interesting performances in predicting the 30-day mortality in acute cholangitis. 展开更多

Thyroid nodules,a common disorder in the endocrine system,require accurate segmentation in ultrasound images for effective diagnosis and treatment.However,achieving precise segmentation remains a challenge due to various factors,including scattering noise,low contrast,and limited resolution in ultrasound images.Although existing segmentation models have made progress,they still suffer from several limitations,such as high error rates,low generalizability,overfitting,limited feature learning capability,etc.To address these challenges,this paper proposes a Multi-level Relation Transformer-based U-Net(MLRT-UNet)to improve thyroid nodule segmentation.The MLRTUNet leverages a novel Relation Transformer,which processes images at multiple scales,overcoming the limitations of traditional encoding methods.This transformer integrates both local and global features effectively through selfattention and cross-attention units,capturing intricate relationships within the data.The approach also introduces a Co-operative Transformer Fusion(CTF)module to combine multi-scale features from different encoding layers,enhancing the model’s ability to capture complex patterns in the data.Furthermore,the Relation Transformer block enhances long-distance dependencies during the decoding process,improving segmentation accuracy.Experimental results showthat the MLRT-UNet achieves high segmentation accuracy,reaching 98.2% on the Digital Database Thyroid Image(DDT)dataset,97.8% on the Thyroid Nodule 3493(TG3K)dataset,and 98.2% on the Thyroid Nodule3K(TN3K)dataset.These findings demonstrate that the proposed method significantly enhances the accuracy of thyroid nodule segmentation,addressing the limitations of existing models. 展开更多

Objective: To explore the application effect of nursing interventions based on APACHE II scores in patients with severe pancreatitis and its impact on the recovery time of the gastrointestinal function. Methods: A total of 86 patients with severe pancreatitis treated in our hospital from March 2023 to March 2024 were selected. Using a random number table method, the patients were divided into a control group receiving conventional nursing care and a study group receiving nursing interventions based on APACHE II scores, with 43 patients in each group. The intervention effects of the two groups were compared. Results: The recovery time of gastrointestinal function in the study group was significantly shorter than that in the control group (P < 0.05). After the intervention, the quality of life scores in the study group was significantly higher than those in the control group (P < 0.05). The incidence of complications in the study group was significantly lower than in the control group (P < 0.05). Conclusion: Nursing interventions based on APACHE II scores can shorten gastrointestinal recovery time and reduce complications in patients with severe pancreatitis, contributing to improved quality of life. 展开更多
