Generalized additive models were used to explore the nonlinear relationships between ultrasonic scores and IBL. Logistic regressions were used to determine the differences in the risk of IBL ≥ 1,500 m L among groups with different ultrasonic scores.Results A total of 332 patients participated in the analysis. Generalized additive models showed a significant positive correlation between score and blood loss. The amount of IBL was increased due to the rise in the ultrasonic score. All cases were divided into three groups according to the scores(low score group: ≤ 6 points, n = 147;median score group: 7-9 points, n = 126;and high score group: ≥ 10 points, n = 59). Compared with the low score group, the high score group showed a higher risk of IBL≥ 1,500 m L [odds ratio, 15.09;95% confidence interval(3.85, 59.19);P ≤ 0.001] after a multivariable adjustment.Conclusions The risk of blood loss equal to or greater than 1,500 m L increases further when ultrasonic score greater than or equal to 10 points, the preparation for transfusion and referral mechanism should be considered.展开更多

The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.展开更多

It is increasingly recognised that early risk assessment is an important part of management, which helps direct appropriate patient care and the timing of endoscopy. Several risk scores have been developed, most of which include endoscopic findings, although a minority do not. These scores were developed to identify various end-points including mortality, rebleeding or clinical intervention in the form of transfusion, endoscopic therapy or surgery. Recent studies have reported accurate identification of a very low risk group on presentation, using scores which require simple clinical or laboratory parameters only. This group may not require admission, but could be managed with early out-patient endoscopy.

文摘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.
文摘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.
文摘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?
文摘BACKGROUND Acute pancreatitis(AP)is an emergency gastrointestinal disease that requires immediate diagnosis and urgent clinical treatment.An accurate assessment and precise staging of severity are essential in initial intensive therapy.AIM To explore the prognostic value of inflammatory markers and several scoring systems[Acute Physiology and Chronic Health Evaluation II,the bedside index of severity in AP(BISAP),Ranson’s score,the computed tomography severity index(CTSI)and sequential organ failure assessment]in severity stratification of earlyphase AP.METHODS A total of 463 patients with AP admitted to our hospital between 1 January 2021 and 30 June 2024 were retrospectively enrolled in this study.Inflammation marker and scoring system levels were calculated and compared between different severity groups.Relationships between severity and several predictors were evaluated using univariate and multivariate logistic regression models.Predictive ability was estimated using receiver operating characteristic curves.RESULTS Of the 463 patients,50(10.80%)were classified as having severe AP(SAP).The results revealed that the white cell count significantly increased,whereas the prognostic nutritional index measured within 48 hours(PNI48)and calcium(Ca^(2+))were decreased as the severity of AP increased(P<0.001).According to multivariate logistic regression,C-reactive protein measured within 48 hours(CRP_(48)),Ca^(2+)levels,and PNI48 were independent risk factors for predicting SAP.The area under the curve(AUC)values for the CRP_(48),Ca^(2+),PNI48,Acute Physiology and Chronic Health Evaluation II,sequential organ failure assessment,BISAP,CTSI,and Ranson scores for the prediction of SAP were 0.802,0.736,0.871,0.799,0.783,0.895,0.931 and 0.914,respectively.The AUC for the combined CRP_(48)+Ca^(2+)+PNI48 model was 0.892.The combination of PNI48 and Ranson achieved an AUC of 0.936.CONCLUSION Independent risk factors for developing SAP include CRP_(48),Ca^(2+),and PNI48.CTSI,BISAP,and the combination of PNI48 and the Ranson score can act as reliable predictors of SAP.
文摘In this article,we discuss the recently published article by Yang et al.This retrospective analysis,which was conducted at a large urban tertiary care center,focused on comparing Lille model scores at days 3 and 7 with established scoring systems and identifying critical clinical predictors,such as renal dysfunction,nutritional status,and underlying cirrhosis.Alcoholic hepatitis(AH),a severe manifestation of alcohol-related liver disease,is associated with high morbidity and mortality,necessitating accurate prognostic tools and comprehensive clinical assessments.Prognostic tools are invaluable for early risk stratification,but they must be contextualized within the multifactorial nature of AH.Acute renal dysfunction and poor nutritional status,for example,are not just complications but pivotal markers of disease severity and systemic impact.Addressing these factors requires a holistic approach that extends beyond scoring systems to include targeted interventions and comprehensive patient care.This editorial emphasizes the need for a paradigm shift in AH management,where prognostic models are complemented by a deeper understanding of patient-specific factors.Such an approach can guide clinicians in tailoring therapies and improving outcomes for this high-risk population.
文摘BACKGROUND Functional gastrointestinal disorders(FGIDs),defined as‘Disorders of Gut-Brain Interaction’,are now considered a global health problem.There is a dearth of concepts and scales to assess the severity of the different symptoms encountered while dealing with the variety of FGIDs as described in the ROME IV classi-fication.We introduced a novel scoring system with the incorporation of 16 different symptoms called Bacharyya’s Questionnaire Scale and started using it while dealing with children suffering from FGIDs.AIM To verify the usefulness and applicability of this recently developed scale,this study was undertaken with the objectives to establish the validity of this scoring system in assessing the severity of symptoms associated with a specific FGID in children and to determine the scoring system's applicability in assessing the treatment response.METHODS The study included children aged 5 to 18 years diagnosed with any FGID based on ROME IV criteria.They completed the newly developed scale and a Visual Analog Scale at initial diagnosis and after a 2-month treatment period.A control group without FGID participated for comparative baseline purposes.Treatment response was defined as a less than or equal to 50%reduction in the total score,which is statistically significant.RESULTS Results from a comprehensive cohort of 190 cases and 90 controls indicated a female preponderance(57.9%)and prevalent disorders such as functional constipation(28%)and functional abdominal pain,not otherwise specified(21%).The grade of FGID(mild,moderate,severe)experienced by the patients was also derived.Post-treatment,96 children demonstrated symptom improvement.The Spearman rank correlation coefficient for pre(r=0.72,95%CI:0.65-0.77,P value<0.0001)and post(r=0.49,95%CI:0.3-0.64,P value<0.0001)treatment data showed positive results with significant P values.CONCLUSION The novel scoring system shows high comprehensibility and gives an objective view of the symptomatology of FGIDs.The use of this novel score in clinical settings will be helpful to typify the FGIDs and may significantly improve decision-making processes to initiate appropriate treatment.

文摘BACKGROUND In recent years,endoscopic resection(ER)has been employed for the excision of submucosal tumors(SMTs).Nonetheless,ER in the duodenum is linked to ele-vated risks of both immediate and delayed hemorrhagic complications and perforations.Satisfactory suturing is crucial for reducing the occurrence of complications.AIM To establish a clinical score model for supporting suture decision-making of duodenal SMTs.METHODS This study included 137 individuals diagnosed with duodenal SMTs who under-went ER.Participants were evenly divided into two groups:A training cohort(TC)comprising 95 cases and an internal validation cohort(VC)with 42 cases.Subsequently,a scoring system was formulated utilizing multivariate logistic regression analysis within the TC,which was then subjected to evaluation in the VC.RESULTS The clinical scoring system incorporated two key factors:Extraluminal growth,which was assigned 2 points,and endoscopic full-thickness resection,which was given 3 points.This model demonstrated strong predictive accuracy,as evidenced by the area under the receiver operating characteristic curve of 0.900(95%confidence interval:0.823-0.976).Additionally,the model’s goodness-of-fit was validated by the Hosmer-Lemeshow test(P=0.404).The probability of purse-string suturing in low(score 0-2)and high(score>3)categories were 3.0%and 64.3%in the TC,and 6.1%and 88.9%in the VC,respectively.CONCLUSION This scoring system may function as a beneficial instrumentality for medical practitioners,facilitating the decision-making process concerning suture techniques in the context of duodenal SMTs.
文摘BACKGROUND The Asia-Pacific Colorectal Screening(APCS)score was designed with the purpose of distinguishing individuals at high risk(HR)for colorectal advanced neoplasia(AN).Traditional Chinese medicine(TCM)constitution was also linked with colorectal cancer(CRC).AIM To integrate the APCS score with TCM constitution identification as a new algorithm to screen for CRC.METHODS A cross-sectional multicenter study was carried out in three hospitals,enrolling 1430 patients who were asymptomatic and undergoing screening colonoscopy from 2022 to 2023.Patients were considered to have average risk,moderate risk,or HR with their APCS score.Odd ratios assessed the relationship between TCM constitution and disease progression.A TCM constitution risk score was created.The sensitivity and specificity of the new algorithm were calculated to evaluate diagnostic performance in detecting advanced adenoma(AA),CRC,and AN.RESULTS Of the 1430 patients,370(25.9%)were categorized as average risk,755(52.8%)as moderate risk,and 305(21.3%)as HR.Using the combined APCS score and the TCM constitution(damp-heat,qi-deficiency,yang-deficiency,phlegm-dampness,and inherited special constitution as positive)algorithm,72.2%of patients with AA and 73.7%of patients with AN were detected.Compared with the APCS score alone,the new algorithm significantly improved the sensitivity for screening AA[72.2%,95%confidence interval(CI):64.4%-80.0%vs 49.2%,95%CI:40.5%-57.9%]and AN(73.7%,95%CI:66.4%-81.1%vs 51.1%,95%CI:42.7%-59.5%).CONCLUSION The combination of APCS and TCM constitution identification questionnaires was valuable in identifying Chinese individuals who were asymptomatic for colorectal screening prioritization.
文摘BACKGROUND Severe symptoms associated with sepsis syndrome(SS)are considered a severe threat,which not only increases therapeutic difficulty but also causes a prognostic mortality rate.However,at present,few related studies focused on the application of different score scales for disease and prognosis assessment in liver cirrhosis(LC)complicated with SS.AIM To determine the correlations of the model for end-stage liver disease(MELD),sequential organ failure assessment(SOFA),and modified early warning score(MEWS)points with the prognosis of patients with LC complicated with SS.METHODS This retrospective analysis included 426 LC cases from February 2019 to April 2022.Of them,225 cases that were complicated with SS were assigned to the LC+SS group,and 201 simple LC cases were included in the LC group.Intergroup differences in MELD,SOFA,and MEWS scores were compared,as well as their diagnostic value for LC+SS.The correlations of the three scores with the progno-sis of patients with LC+SS were further analyzed,as well as the related risk factors affecting patients’outcomes,after the follow-up investigation.RESULTS MELD,SOFA,and MEWS scores were all higher in the LC+SS group vs the LC group,and their combined assessment for LC+SS revealed a diagnostic sensi-tivity and a specificity of 89.66%and 90.84%,respectively(P<0.05).The LC+SS group reported 58 deaths,with an overall mortality rate of 25.78%.Deceased pa-tients presented higher MELD,SOFA,and MEWS points than those who survived(P<0.05).MELD,SOFA,and MEWS scores were determined by COX analysis as factors independently affecting the prognosis of patients with LC+SS(P<0.05).CONCLUSION MELD,SOFA,and MEWS effectively diagnosed LC in patients complicated with SS,and they demonstrated great significance in assessing prognosis,which provides a reliable prognosis guarantee for patients with LC+SS.However,their assessment effects remain limited,which is worthy of further investigation by more in-depth and rigorous experimental analysis.

文摘Acute pancreatitis(AP)is a potentially life-threatening inflammatory disease of the pancreas,with clinical management determined by the severity of the disease.Diagnosis,severity prediction,and prognosis assessment of AP typically involve the use of imaging technologies,such as computed tomography,magnetic resonance imaging,and ultrasound,and scoring systems,including Ranson,Acute Physiology and Chronic Health Evaluation II,and Bedside Index for Severity in AP scores.Computed tomography is considered the gold standard imaging modality for AP due to its high sensitivity and specificity,while magnetic resonance imaging and ultrasound can provide additional information on biliary obstruction and vascular complications.Scoring systems utilize clinical and laboratory parameters to classify AP patients into mild,moderate,or severe categories,guiding treatment decisions,such as intensive care unit admission,early enteral feeding,and antibiotic use.Despite the central role of imaging technologies and scoring systems in AP management,these methods have limitations in terms of accuracy,reproducibility,practicality and economics.Recent advancements of artificial intelligence(AI)provide new opportunities to enhance their performance by analyzing vast amounts of clinical and imaging data.AI algorithms can analyze large amounts of clinical and imaging data,identify scoring system patterns,and predict the clinical course of disease.AI-based models have shown promising results in predicting the severity and mortality of AP,but further validation and standardization are required before widespread clinical application.In addition,understanding the correlation between these three technologies will aid in developing new methods that can accurately,sensitively,and specifically be used in the diagnosis,severity prediction,and prognosis assessment of AP through complementary advantages.

文摘Objective This study aims to investigate the correlation of an ultrasonic scoring system with intraoperative blood loss(IBL) in placenta accreta spectrum(PAS) disorders.Methods A retrospective cohort study was conducted between January 2015 and November 2019.Clinical data for patients with PAS have been obtained from medical records. Generalized additive models were used to explore the nonlinear relationships between ultrasonic scores and IBL. Logistic regressions were used to determine the differences in the risk of IBL ≥ 1,500 m L among groups with different ultrasonic scores.Results A total of 332 patients participated in the analysis. Generalized additive models showed a significant positive correlation between score and blood loss. The amount of IBL was increased due to the rise in the ultrasonic score. All cases were divided into three groups according to the scores(low score group: ≤ 6 points, n = 147;median score group: 7-9 points, n = 126;and high score group: ≥ 10 points, n = 59). Compared with the low score group, the high score group showed a higher risk of IBL≥ 1,500 m L [odds ratio, 15.09;95% confidence interval(3.85, 59.19);P ≤ 0.001] after a multivariable adjustment.Conclusions The risk of blood loss equal to or greater than 1,500 m L increases further when ultrasonic score greater than or equal to 10 points, the preparation for transfusion and referral mechanism should be considered.

文摘AIM:To ascertain the usefulness of a histological scoring system devised to assist in the interpretation of liver histology in neonatal cholestasis(NC) .METHODS:Liver biopsy specimens obtained from infants with NC referred to a tertiary pediatric unit in Malaysia were prospectively studied.The first author,blinded to the final diagnosis,devised the histological diagnosis based on a 7-feature(portal ductal proliferation,bile plugs in portal ductules,portoportal bridging,lymphocytic infiltration in portal region,multinucleated hepatocytes,neutrophilic infiltration,hepatocellular swelling) ,15-point(0 to 15) scoring system.The author classified the histological diagnosis as either biliary atresia(BA) or neonatal hepatitis(NH,all other diagnoses) ,and subsequently compared the author's diagnosis with the final diagnosis.RESULTS:Eighty-four biopsy specimens obtained from 78 patients were reviewed.Without the scoring system,BA was correctly diagnosed by the author histologically in 30 cases,labelled as NH in 3.For other diagnoses,BA was excluded correctly in 33 cases and mislabeled as BA in 2 cases.The overall sensitivity for BA was 91%,specificity 86% and accuracy 88%.With the scoring system,a score of ≥ 7 had the best diagnostic utility to differentiate BA from other intrahepatic cholestasis histologically(sensitivity 88%,specificity 94%,accuracy 92%) .Four patients with a score < 7 had BA,and 3 patients with a score ≥ 7 had NH.CONCLUSION:A 7-feature,15-point histological scoring system had good diagnostic accuracy in the interpretation of liver histology in neonatal cholestasis.
文摘AIM:To establish a predictive algorithm which may serve for selecting optimal candidates for interferon-α(IFN-α) treatment.METHODS:A total of 474 IFN-α treated hepatitis B virus e antigen(HBeAg)-positive patients were enrolled in the present study.The patients' baseline characteristics,such as age,gender,blood tests,activity grading(G) of intrahepatic inflammation,score(S) of liver fibrosis,hepatitis B virus(HBV) DNA and genotype were evaluated;therapy duration and response of each patient at the 24th wk after cessation of IFN-α treatment were also recorded.A predictive algorithm and scoring system for a sustained combined response(CR) to IFN-α therapy were established.About 10% of the patients were randomly drawn as the test set.Responses to IFN-α therapy were divided into CR,partial response(PR) and non-response(NR).The mixed set of PR and NR was recorded as PR+NR.RESULTS:Stratified by therapy duration,the most significant baseline predictive factors were alanine aminotransferase(ALT),HBV DNA level,aspartate aminotransferase(AST),HBV genotype,S,G,age and gender.According to the established model,the accuracies for sustained CR and PR+NR,respectively,were 86.4% and 93.0% for the training set,81.5% and 91.0% for the test set.For the scoring system,the sensitivity and specificity were 78.8% and 80.6%,respectively.There were positive correlations between ALT and AST,and G and S,respectively.CONCLUSION:With these models,practitioners may be able to propose individualized decisions that have an integrated foundation on both evidence-based medicine and personal characteristics.

文摘The prognostic value of T category for locoregional control in patients with nasopharyngeal carcinoma(NPC)has decreased with the extensive use of intensity-modulated radiotherapy(IMRT).We aimed to develop a prognostic scoring system(PSS)that incorporated tumor extension and clinical characteristics for locoregional control in NPC patients treated with IMRT.The magnetic resonance imaging scans and medical records of 717 patients with nonmetastatic NPC treated with IMRT at Sun Yat-sen University Cancer Center between January 2003 and January 2008 were reviewed.Age,pathologic classification,primary tumor extension,primary gross tumor volume(GTV-p),T and N categories,and baseline lactate dehydrogenase(LDH)level were analyzed.Hierarchical cluster analysis as well as univariate and multivariate analyses were used to develop the PSS.Independent prognostic factors for locoregional relapse included N2–3 stage,GTV-p≥26.8 mL,and involvement of one or more structures within cluster3.We calculated a risk score derived from the regression coefficient of each factor and classified patients into four groups:low risk(score 0),intermediate risk(score>0 and≤1),high risk(score>1 and≤2),and extremely high risk(score>2).The 5-year locoregional control rates for these groups were 97.4%,93.6%,85.2%,and 78.6%,respectively(P<0.001).We have developed a PSS that can help identify NPC patients who are at high risk for locoregional relapse and can guide individualized treatments for NPC patients.

文摘AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic hepatitis.METHODS We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.

文摘Objective:This study aimed to develop and validate a risk scoring system to identify high-risk individuals carrying malignant lesions in stomach for tailored gastric cancer screening.Methods:A gastric cancer risk scoring system(GC-RSS)was developed based on questionnaire-based predictors for gastric cancer derived from systematic literature review.To assess the capability of this system for discrimination,risk scores for 8,214 and 7,235 outpatient subjects accepting endoscopic examination in two endoscopy centers,and 32,630 participants in a community-based cohort in China were calculated to plot receiver operating characteristic curves and generate area under the curve(AUC).To evaluate the performance of GC-RSS,the screening proportion,sensitivity and detection rate ratio compared to universal screening were used under different risk score cutoff values.Results:GC-RSS comprised nine predictors including advanced age,male gender,low body mass index(<18.5 kg/m^(2)),family history of gastric cancer,cigarette smoking,consumption of alcohol,preference for salty food,irregularity of meals and consumption of preserved food.This tool performed well in determining the risk of malignant gastric lesions with AUCs of 0.763,0.706 and 0.696 in three validation sets.When subjects with risk scores≥5 were evaluated with endoscopy,nearly 50%of these endoscopies could be saved with a detection rate of over 1.5 times achieved.When the cutoff was set at 8,only about 10%of subjects with the highest risk would be offered endoscopy,and detection rates for gastric cancer could be increased 2-4 fold compared to universal screening.Conclusions:An effective questionnaire-based GC-RSS was developed and validated.This tool may play an important role in establishing a tailored screening strategy for gastric cancer in China.
文摘Upper gastrointestinal haemorrhage (UGIH) remains a common medical emergency worldwide. It is increasingly recognised that early risk assessment is an important part of management, which helps direct appropriate patient care and the timing of endoscopy. Several risk scores have been developed, most of which include endoscopic findings, although a minority do not. These scores were developed to identify various end-points including mortality, rebleeding or clinical intervention in the form of transfusion, endoscopic therapy or surgery. Recent studies have reported accurate identification of a very low risk group on presentation, using scores which require simple clinical or laboratory parameters only. This group may not require admission, but could be managed with early out-patient endoscopy. This article aims to describe the existing pre- and post-endoscopy risk scores for UGIH and assess the published data comparing them in the prediction of outcome. Recent data assessing their use in clinical practice, in particular the early identification of low-risk patients, are also discussed.

文摘Objective:To develop and validate a radiomics prognostic scoring system(RPSS)for prediction of progressionfree survival(PFS)in patients with stageⅣnon-small cell lung cancer(NSCLC)treated with platinum-based chemotherapy.Methods:In this retrospective study,four independent cohorts of stageⅣNSCLC patients treated with platinum-based chemotherapy were included for model construction and validation(Discovery:n=159;Internal validation:n=156;External validation:n=81,Mutation validation:n=64).First,a total of 1,182 three-dimensional radiomics features were extracted from pre-treatment computed tomography(CT)images of each patient.Then,a radiomics signature was constructed using the least absolute shrinkage and selection operator method(LASSO)penalized Cox regression analysis.Finally,an individualized prognostic scoring system incorporating radiomics signature and clinicopathologic risk factors was proposed for PFS prediction.Results:The established radiomics signature consisting of 16 features showed good discrimination for classifying patients with high-risk and low-risk progression to chemotherapy in all cohorts(All P<0.05).On the multivariable analysis,independent factors for PFS were radiomics signature,performance status(PS),and N stage,which were all selected into construction of RPSS.The RPSS showed significant prognostic performance for predicting PFS in discovery[C-index:0.772,95%confidence interval(95%CI):0.765-0.779],internal validation(C-index:0.738,95%CI:0.730-0.746),external validation(C-index:0.750,95%CI:0.734-0.765),and mutation validation(Cindex:0.739,95%CI:0.720-0.758).Decision curve analysis revealed that RPSS significantly outperformed the clinicopathologic-based model in terms of clinical usefulness(All P<0.05).Conclusions:This study established a radiomics prognostic scoring system as RPSS that can be conveniently used to achieve individualized prediction of PFS probability for stageⅣNSCLC patients treated with platinumbased chemotherapy,which holds promise for guiding personalized pre-therapy of stageⅣNSCLC.
