High molecular weight glutenin subunits （HMW-GS） in wheat are important protein subunits, which affect flour quality. To improve breeding and selection efficiency of wheat varieties which are used in making hand-extended noodle, 100 spring wheat varieties were selected to study the importance of HMW-GS on noodle quality score indexes such as color, appearance, taste agreeability, toughness, stickiness, smoothness, taste, and total score, through methods of quantity theory and statistic evaluation. It was shown that the hand-extended noodle quality score of HMW-GS 1, 2°, N, 7, 7 ＋ 8, 17 ＋ 18, 22, 2 ＋ 10, 2 ＋ 11, 2＋ 12, 5 ＋ 10, and 10 was 5.40, 5.35, 0, 2.55, 2.56, 9.19, 0.05, 0.15, 1.49, 1.14, 10.00, and 5.14, respectively. The score system for hand-extended noodle quality based on HMW-GS index included eight multiple linear regression equations （R^2 〉 0.98）. Hence, using the HMW-GS composition, the eight hand-extended noodle quality indexes would be forecasted exactly. Results indicated that ideal subunit compositions of HMW-GS for this special usage were composition 1, 17 ＋ 18, 5 ＋ 10, or composition 2°, 17 ＋ 18, 5 ＋ 10. This standard could be used on variety selection in the early generation of breeding crosses. HMW-GS 2 ＋ 10, 2 ＋ 11, and 2 ＋ 12 were the least desirable subunits for hand-extended noodle, which should be avoided in wheat variety selection aimed for hand-extended noodle flour use.展开更多

Adults with acute diarrhea （n=424） were enrolled in the study. Logistic regression and standard regression coefficients were used to formulate the Early Warning Infectivity Score System for Adults with Acute Bacterial Diarrhea （EWIS-ABD）. Four risk factors were identified by logistic regression, including body temperature （P〈0.01）, abdominal pain （P〈0.01）, leukocyte count in stool （P〈0.01）, and unclean dietary history （P〈0.01）. EWIS-ABD was thus developed, in which the value 〉5 points was set as an indicator of bacterial diarrhea. The incidence of bacterial diarrhea increased along with the elevated score. EWIS-ABD was more specific for bacterial diarrhea than for viral diarrhea. The accuracy and reliability of EWIS-ABD was high by prospective validation in 478 patients with acute diarrhea.展开更多

Some studies revealed that visual experience in early life affected the final myopia, indicating that environmental factors play an impellent role in the development of myopia. However, risk factors of myopia are still not identified among adolescents in China. A total of 4104 cases of myopia symptom and 3306 emmetropia controls were selected from students in primary and middle schools in Wuhan in 2008. We identified the risk factors associated with myopia symptom by multivariate logistic regression in this cross-sectional study and constructed a risk score system for myopia symptom. The value of the area under the receiver operating characteristic curve (ROC) was 0.735. Furthermore, we followed up 93 students aged 7-9 years for one year and calculated the total points using the score system. We found no significant difference between the final myopia symptom and the results predicted by the total points by pair chi-square test (P>0.05). The score system had a modest ability to estimate the risk factors of myopia symptom. Using this score system, we could identify the students who are at risk of myopia symptom in the future according to their behaviors and environmental factors, and take measures to slow the progress of myopia symptom.展开更多

Eighteen cases were excluded from our study due to primary failure（10 cases）,incomplete medical notes（5 cases）and follow-up less than 1y（3cases）. We included 134 PKPs from 134 patients stratified by preoperative risk score. Spearman coefficient was calculated for the relationship between the score obtained and risk of failure at 1y. Univariate and multivariate analysis were calculated for the impact of every single risk factor included in the RSS over graft failure at 1y. RESULTS：Spearman coefficient showed statistically significant correlation between the score in the RSS and graft failure（P〈0.05）. Multivariate logistic regression analysis showed no statistically significant relationship（P〉0.05）between diagnosis and lens status with graft failure. The relationship between the other risk factors studied and graft failure was significant（P〈0.05）,although the results for previous grafts and graft failure was unreliable. None of our patients had previous blood transfusion,thus,it had no impact. CONCLUSION：After the application of multivariate analysis techniques,some risk factors do not show the expected impact over graft failure at 1y.展开更多

By using the method of radiomics analysis, 591 computed tomography(CT)-based radiomics features were extracted, and the radiomics-based classifier was constructed. Then, using multivariable logistic regression analysis, a weighted score RPRS was derived to identify LN metastasis. Apparent prediction performance of RPRS was assessed with its calibration,discrimination, and clinical usefulness.Results: The radiomics-based classifier was constructed, which consisted of 13 selected radiomics features.Multivariate models demonstrated that radiomics-based classifier, age group, tumor diameter, tumor location, and CT-based LN status were independent predictors. When we assigned the corresponding score to each variable,patients with RPRSs of 0-3, 4-5, 6, 7-8, and 9 had distinctly very low(0%-20%), low(21%-40%), intermediate(41%-60%), high(61%-80%), and very high(81%-100%) risks of LN involvement, respectively. The developed RPRS showed good discrimination and satisfactory calibration (C-index: 0.785, 95% confidence interval(95% CI):0.780-0.790)Additionally, RPRS outperformed the clinicopathologic-based characteristics model with net reclassification index(NRI) of 0.711(95% CI: 0.555-0.867).Conclusions: The novel clinical scoring system developed as RPRS can serve as an easy-to-use tool to facilitate the preoperatively individualized prediction of LN metastasis in patients with resectable NSCLC. This stratification of patients according to their LN status may provide a basis for individualized treatment.展开更多

Demographic and comorbidity information was collected. In a single visit, patients were administered the RAFIS. The results obtained with the new score were compared with those of both Wexner score and faecal incontinence quality of life scale(FIQL) questionnaire. The patient withoutinfluence of the surgeon completed the test. The role of surgeon was explaining the meaning of each section and how he had to fill. Reliability of the RAFIS score was measured using intra-observer agreement and Cronbach's alpha(internal consistency) coefficient. Multivariate analysis of the main components within the different scores was performed in order to determine whether all the scores measured the same factor and to conclude whether the information could be encompassed in a single factor. A sample size of 50 patients with faecal incontinence was estimated to be enough to detect a correlation of 0.55 or better at 5% level of significance with 80% power.RESULTS: We analysed the results obtained by 53 consecutive patients with faecal incontinence(median age 61.55 ± 12.49 years) in the three scoring systems. A total of 208 healthy volunteers(median age 58.41 ± 18.41 years) without faecal incontinence were included in the study as negative controls. Pearson's correlation coefficient between "state" and "leaks" was excellent(r = 0.92, P < 0.005). Internal consistency in the comparison of "state" and "leaks" yielded also excellent correlation(Cronbach's α = 0.93). Results in each score were compared using regression analysis and a correlation value of r = 0.98 was obtained with Wexner score. As regards FIQL questionnaire, the values of "r " for the different subscales of the questionnaire were: "lifestyle" r =-0.87, "coping/behaviour" r =-0.91, "depression" r =-0.36 and "embarrassment" r =-0.90,(P < 0.01). A multivariate analysis showed that all the scoring systems measured the same factor. A single factor may explain 80.84% of the variability of FI, so all the scoring systems measure the same factor. Patient's continence improves when RAFIS and Jorge-Wexner scores show low values and when the values obtained in the FIQL questionnaire are high.CONCLUSION: RAFIS is a valid and reliable tool to assess Faecal Incontinence.展开更多

PF) computerized adaptive test(CAT), hip disability and osteoarthritis outcome score for joint reconstruction(HOOS JR), and the knee injury and osteoarthritis outcome score for joint reconstruction(KOOS JR) from February 2014 to April 2017. MCIDs were calculated using anchorbased and distribution-based methods. Patient reports of meaningful change in function since their first clinic encounter were used as an anchor.RESULTS There were 2226 patients who participated with a mean age of 61.16(SD = 12.84) years, 41.6% male, and 89.7% Caucasian. Mean change ranged from 7.29 to 8.41 for the PROMIS~? PF CAT, from 14.81 to 19.68 for the HOOS JR, and from 14.51 to 18.85 for the KOOS JR. ROC cut-offs ranged from 1.97-8.18 for the PF CAT, 6.33-43.36 for the HOOS JR, and 2.21-8.16 for the KOOS JR. Distribution-based methods estimated MCID values ranging from 2.45 to 21.55 for the PROMIS~? PF CAT; from 3.90 to 43.61 for the HOOS JR, and from 3.98 to 40.67 for the KOOS JR. The median MCID value in the range was similar to the mean change score for each measure and was 7.9 for the PF CAT, 18.0 for the HOOS JR, and 15.1 for the KOOS JR.CONCLUSION This is the first comprehensive study providing a wide range of MCIDs for the PROMIS? PF, HOOS JR, and KOOS JR in orthopaedic patients with joint ailments.展开更多
文摘Hand-extended noodle, a special kind of noodle, requires particular quality flour to make it. High molecular weight glutenin subunits （HMW-GS） in wheat are important protein subunits, which affect flour quality. To improve breeding and selection efficiency of wheat varieties which are used in making hand-extended noodle, 100 spring wheat varieties were selected to study the importance of HMW-GS on noodle quality score indexes such as color, appearance, taste agreeability, toughness, stickiness, smoothness, taste, and total score, through methods of quantity theory and statistic evaluation. It was shown that the hand-extended noodle quality score of HMW-GS 1, 2°, N, 7, 7 ＋ 8, 17 ＋ 18, 22, 2 ＋ 10, 2 ＋ 11, 2＋ 12, 5 ＋ 10, and 10 was 5.40, 5.35, 0, 2.55, 2.56, 9.19, 0.05, 0.15, 1.49, 1.14, 10.00, and 5.14, respectively. The score system for hand-extended noodle quality based on HMW-GS index included eight multiple linear regression equations （R^2 〉 0.98）. Hence, using the HMW-GS composition, the eight hand-extended noodle quality indexes would be forecasted exactly. Results indicated that ideal subunit compositions of HMW-GS for this special usage were composition 1, 17 ＋ 18, 5 ＋ 10, or composition 2°, 17 ＋ 18, 5 ＋ 10. This standard could be used on variety selection in the early generation of breeding crosses. HMW-GS 2 ＋ 10, 2 ＋ 11, and 2 ＋ 12 were the least desirable subunits for hand-extended noodle, which should be avoided in wheat variety selection aimed for hand-extended noodle flour use.
文摘AIM:To suggest a new cleansing score system for small bowel preparation and to evaluate its clinical efficacy.METHODS:Twenty capsule endoscopy cases were reviewed and small bowel preparation was assessed with the new scoring system.For the assessment,two visual parameters were used:proportion of visualized mucosa and degree of obscuration.Representative frames from small bowel images were serially selected and scored at 5-min intervals.Intraclass correlation coefficient(ICC)was obtained to assess the reliability of the new scoring system.For efficacy evaluation and validation,scores of our new scoring system were compared with another previously reported cleansing grading system.RESULTS:Concordance with the previous system,inter-observer agreement,and intra-patient agreement were excellent with ICC values of 0.82,0.80,and 0.76,respectively.The intra-observer agreements at four-week intervals were also excellent.The cutoff value of adequate image quality was found to be 2.25.CONCLUSION:Our new scoring system is simple,efficient,and can be considered to be applicable in clinical practice and research.

文摘The aim of our study was to develop a scoring system to predict whether diarrhea is of a bacterial origin and whether the diarrheal patients constitute a potential source of infection to others. Adults with acute diarrhea （n=424） were enrolled in the study. Logistic regression and standard regression coefficients were used to formulate the Early Warning Infectivity Score System for Adults with Acute Bacterial Diarrhea （EWIS-ABD）. Four risk factors were identified by logistic regression, including body temperature （P〈0.01）, abdominal pain （P〈0.01）, leukocyte count in stool （P〈0.01）, and unclean dietary history （P〈0.01）. EWIS-ABD was thus developed, in which the value 〉5 points was set as an indicator of bacterial diarrhea. The incidence of bacterial diarrhea increased along with the elevated score. EWIS-ABD was more specific for bacterial diarrhea than for viral diarrhea. The accuracy and reliability of EWIS-ABD was high by prospective validation in 478 patients with acute diarrhea.
文摘Myopia is the leading cause of visual impairments worldwide. Some studies revealed that visual experience in early life affected the final myopia, indicating that environmental factors play an impellent role in the development of myopia. However, risk factors of myopia are still not identified among adolescents in China. A total of 4104 cases of myopia symptom and 3306 emmetropia controls were selected from students in primary and middle schools in Wuhan in 2008. We identified the risk factors associated with myopia symptom by multivariate logistic regression in this cross-sectional study and constructed a risk score system for myopia symptom. The value of the area under the receiver operating characteristic curve (ROC) was 0.735. Furthermore, we followed up 93 students aged 7-9 years for one year and calculated the total points using the score system. We found no significant difference between the final myopia symptom and the results predicted by the total points by pair chi-square test (P>0.05). The score system had a modest ability to estimate the risk factors of myopia symptom. Using this score system, we could identify the students who are at risk of myopia symptom in the future according to their behaviors and environmental factors, and take measures to slow the progress of myopia symptom.

文摘Coronavirus disease 2019(COVID-19)has become a worldwide pandemic.Hospitalized patients of COVID-19 suffer from a high mortality rate,motivating the development of convenient and practical methods that allow clinicians to promptly identify high-risk patients.Here,we have developed a risk score using clinical data from 1479 inpatients admitted to Tongji Hospital,Wuhan,China(development cohort)and externally validated with data from two other centers:141 inpatients from Jinyintan Hospital,Wuhan,China(validation cohort 1)and 432 inpatients from The Third People’s Hospital of Shenzhen,Shenzhen,China(validation cohort 2).The risk score is based on three biomarkers that are readily available in routine blood samples and can easily be translated into a probability of death.The risk score can predict the mortality of individual patients more than 12 d in advance with more than 90%accuracy across all cohorts.Moreover,the Kaplan-Meier score shows that patients can be clearly differentiated upon admission as low,intermediate,or high risk,with an area under the curve(AUC)score of 0.9551.In summary,a simple risk score has been validated to predict death in patients infected with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2);it has also been validated in independent cohorts.
文摘BACKGROUND Bone metastasis has various negative impacts.Activities of daily living(ADL)and quality of life(QOL)can be significantly decreased,survival may be impacted,and medical expenses may increase.It is estimated that at least 5%cancer patients might be suffering from bone metastases.In 2016,we published the Comprehensive Guidelines for the Diagnosis and Treatment of Bone Metastasis.Since then,the therapeutic outcomes for patients have gradually improved.As life expectancy is a major determinant of surgical intervention,the strategy should be modified if the prolongation of survival is to be achieved.AIM To monitor how bone metastasis treatment has changed before and after launch of our guidelines for bone metastasis.METHODS For advanced cancer patients with bone metastasis who visited the Department of Clinical Oncology at Akita University hospital between 2012 and 2023,parameters including the site and number of bone metastases,laboratory data,and survival time,were extracted from electronic medical records and the Katagiri score was calculated.The association with survival was determined for each factor.RESULTS Data from 136 patients were obtained.The 1-year survival rate for the poor prognosis group with a higher Katagiri score was 20.0%in this study,which was 6%and an apparent improvement from 2014 when the scoring system was developed.Other factors significantly affecting survival included five or more bone metastases than less(P=0.0080),and treatment with chemotherapy(P<0.001),bone modifying agents(P=0.0175)and immune checkpoint inhibitors(P=0.0128).In recent years,advances in various treatment methods have extended the survival period for patients with advanced cancer.It is necessary not only to simply extend survival time,but also to maintain ADL and improve QOL.CONCLUSION Various therapeutic interventions including surgical approach for bone metastasis,which is a disorder of locomotor organs,are increasingly required.Guidelines and scoring system for prognosis need to be revised promptly.
文摘AIM：To analyze the relationship between the score obtained in the Risk Score System（RSS）proposed by Hicks et al with penetrating keratoplasty（PKP）graft failure at 1y postoperatively and among each factor in the RSS with the risk of PKP graft failure using univariate and multivariate analysis.METHODS：The retrospective cohort study had 152 PKPs from 152 patients. Eighteen cases were excluded from our study due to primary failure（10 cases）,incomplete medical notes（5 cases）and follow-up less than 1y（3cases）. We included 134 PKPs from 134 patients stratified by preoperative risk score. Spearman coefficient was calculated for the relationship between the score obtained and risk of failure at 1y. Univariate and multivariate analysis were calculated for the impact of every single risk factor included in the RSS over graft failure at 1y. RESULTS：Spearman coefficient showed statistically significant correlation between the score in the RSS and graft failure（P〈0.05）. Multivariate logistic regression analysis showed no statistically significant relationship（P〉0.05）between diagnosis and lens status with graft failure. The relationship between the other risk factors studied and graft failure was significant（P〈0.05）,although the results for previous grafts and graft failure was unreliable. None of our patients had previous blood transfusion,thus,it had no impact. CONCLUSION：After the application of multivariate analysis techniques,some risk factors do not show the expected impact over graft failure at 1y.
文摘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.
文摘BACKGROUND Clinical predictors of dengue fever are crucial for guiding timely management and avoiding life-threatening complications.While prognostic scores are available,a systematic evaluation of these tools is lacking.AIM To evaluate the performance and accuracy of various proposed dengue clinical prognostic scores.METHODS Three databases,PubMed,EMBASE and Cochrane,were searched for peer-reviewed studies published from inception to 4 September 2023.Studies either developing or validating a prognostic model relevant to dengue fever were included.A total of 29 studies(n=17910)were included.RESULTS Most commonly studied outcomes were severe dengue(15 models)and mortality(8 models).For the paediatric population,Bedside Dengue Severity Score by Gayathri et al(specificity=0.98)and the nomogram model by Nguyen et al(sensitivity=0.87)performed better.For the adult population,the most specific model was reported by Leo et al(specificity=0.98).The most sensitive score is shared between Warning Signs for Severe Dengue as reported by Leo et al and Model 2 by Lee et al(sensitivity=1.00).CONCLUSION While several models demonstrated precision and reliability in predicting severe dengue and mortality,broader application across diverse geographic settings is needed to assess their external validity.
文摘Emphysematous pyelonephritis(EPN)is a severe,a lethal necrotizing upper urinary tract infection,characterized by gas production within the renal pa-renchyma,collecting system,or perinephric tissue.EPN is emerging as a sig-nificant concern,necessitating early diagnosis,severity assessment,and timely intervention to improve outcomes.This study proposes a modified National Early Warning Score 2(mNEWS 2)to enhance risk stratification and predictive accuracy in EPN management.The mNEWS 2 refines the original NEWS 2 system,which aggregates 6 physiological indicators(body temperature,systolic blood pressure,pulse rate,oxygen saturation,breathing rate,and degree of consciousness),by incorporating weighted risk stratification indices and specific cutoff values derived from clinical observations,statistical modeling,and predictive per-formance analysis.A pilot study identified optimal thresholds,with a score of 15 maximizing predictive performance for mortality risk and intervention needs,validated through receiver operating characteristic curve analysis.So,the mNEWS 2 score represents a significant advancement in EPN management,offering improved risk stratification and treatment outcomes.
文摘This editorial comment is on the article by Xu et al.It offers an in-depth analysis of liver function assessment tools and their prognostic roles in non-malignant liver diseases,with a focus on the albumin-bilirubin(ALBI)score.ALBI’s components,grading system,and clinical relevance across various liver conditions are reviewed and compared with traditional models such as the Child-Pugh and model for end-stage liver disease scores.We included recent studies evaluating ALBI’s role in estimating liver function,suggesting it may help differentiate patients who appear similar under other staging systems,and assist in guiding clinical decisions.Although ALBI is primarily used as an indicator of hepatic reservoir in hepatocellular carcinoma,it has been demonstrated a positive correlation with overall survival,tumor recurrence,and post-hepatectomy liver failure in patients undergoing potentially curative treatments such as liver resection,liver transplantation,and local ablation.Moreover,several studies suggest that ALBI can also predict survival outcomes,treatment-related toxicity,and liver-related complications in patients receiving trans-arterial chemoembolization,radioembolization,external-beam radiotherapy,or systemic therapies.Its growing use in nonmalignant liver diseases,including primary biliary cholangitis,cirrhosis,acute and chronic liver failure,and viral hepatitis highlights the need for large,prospective studies.Further studies are warranted to validate the integration of ALBI into routine clinical practice and to clarify its role in guiding prognosis and treatment planning.

文摘BACKGROUND Patients with inflammatory bowel disease(IBD)are at an increased risk of bacterial pneumonia,contributing to significant morbidity and mortality.While previous studies have identified various risk factors,including medications and comorbidities,the independent contribution of IBD to pneumonia risk remains unclear.We hypothesized that the increased pneumonia risk is primarily driven by factors other than IBD itself.AIM To investigate the relative contributions of IBD,comorbidities,and medications to pneumonia risk in patients with IBD.METHODS We conducted a retrospective cohort study using the All of Us Research Program database(2010-2022).We matched 2810 participants with IBD 1:1 with controls using four propensity score models:(1)Demographics/Lifestyle only;(2)Plus comorbidities;(3)Plus medications;and(4)All factors combined.Then we used Cox proportional hazards models to assess pneumonia risk and logistic regression to evaluate risk factors.RESULTS In the primary analysis of 5620 matched participants,IBD was not independently associated with increased pneumonia risk[hazard ratio(HR)=1.07,95%CI:0.84-1.35]when matched for all factors.However,participants with IBD had significantly higher risk(HR=2.08,95%CI:1.56-2.78)when matched only for demographics and lifestyle factors.Within the IBD cohort,a high comorbidity burden(Charlson Comorbidity Index≥10)[odds ratio(OR)=12.20,95%CI:6.69-23.00]and systemic steroid use(OR=2.26,95%CI:1.21-4.64)were independently associated with increased pneumonia risk.CONCLUSION Comorbidities and systemic steroids,rather than IBD itself,drive pneumonia risk.Management should focus on these factors and prioritize vaccination in high-risk patients.
文摘Ossiculoplasty remains a challenging surgical procedure,with outcomes heavily influenced by diverse anatomical and pathological factors.Over the decades,numerous scoring systems have been developed to predict the prognosis of ossiculoplasty,each emphasizing different variables such as ossicular status,middle ear environment,and surgical history.This paper provides a comprehensive review of the evolution of prognostic scoring systems,including Austin's original ossicular classification,Bellucci's otorrhea staging,the Middle Ear Risk Index(MERI),the Ossiculoplasty Outcome Parameter Staging(OOPS),and the recently introduced Ear Environment Risk(EER)scale.While these systems have significantly contributed to preoperative assessment,each presents notable limitations in encompassing all variables affecting surgical success.Therefore,the aim of this paper is to provide a review of the ossiculoplasty prognostic scores and show the benefits,innovations and gaps associated with each.To address these gaps,a novel,modified scoring system is proposed,incorporating previously overlooked but clinically significant factors such as tympanic membrane status,type of tympanoplasty,ossicular replacement material,CT scan findings,and the presence of complicated ear conditions.By synthesizing elements from historical scores with updated clinical insights,the proposed system aims to provide a more holistic and predictive framework for preoperative evaluation.Future multicenter studies are encouraged to validate the efficacy and prognostic power of this new scoring system,with the goal of improving surgical planning and patient counseling in ossiculoplasty.

文摘Traditional psychiatric diagnosis relies on subjective symptom assessment,lacking objective biomarkers that hinder early detection and personalized treatment.Plasma proteins and polygenic risk score(PRS),as potential predictive tools,hold promise for advancing early diagnosis of mental disorders.This study aims to evaluate the predictive potential of proteomic features and PRS in multiple mental illnesses(depression,schizophrenia,and post-traumatic stress disorder(PTSD)).Using participant data from the UK Biobank-Pharma Proteomics Project,we screen protein associations with mental disorders through least absolute shrinkage and selection operator(LASSO)analysis and construct a Cox regression risk prediction model by integrating the PRS.Additionally,we evaluate predictive performance using 6 machine learning methods and Kaplan-Meier survival curves.Our findings reveal distinct predictive patterns across dis-orders.For depression,integrating plasma proteins with PRS significantly improves prediction beyond the clinical model(C-index=0.6322).For schizophrenia,adding plasma proteins enhances predictive performance,whereas PRS provides no significant improvement.For PTSD,neither plasma proteins nor PRS add substantial predictive value beyond clinical variables.Risk stratification analysis demonstrat that all three mental disorders models can clearly distinguish high-risk from low-risk groups(depression:HR=2.34,P<0.001;schizophrenia:HR=5.47,P<0.001;PTSD:HR=3.02,P<0.001).Al-though it shows good performance in short-term prediction,its long-term prediction ability has decreased,and it needs to be further optimized in the future.This study underscores the differential utility of biomarkers across mental disorders and provides a rationale for disorder-specific predictive modeling in precision psychiatry.

文摘Objective: To develop and validate a radiomics-based predictive risk score(RPRS) for preoperative prediction of lymph node(LN) metastasis in patients with resectable non-small cell lung cancer(NSCLC).Methods: We retrospectively analyzed 717 who underwent surgical resection for primary NSCLC with systematic mediastinal lymphadenectomy from October 2007 to July 2016. By using the method of radiomics analysis, 591 computed tomography(CT)-based radiomics features were extracted, and the radiomics-based classifier was constructed. Then, using multivariable logistic regression analysis, a weighted score RPRS was derived to identify LN metastasis. Apparent prediction performance of RPRS was assessed with its calibration,discrimination, and clinical usefulness.Results: The radiomics-based classifier was constructed, which consisted of 13 selected radiomics features.Multivariate models demonstrated that radiomics-based classifier, age group, tumor diameter, tumor location, and CT-based LN status were independent predictors. When we assigned the corresponding score to each variable,patients with RPRSs of 0-3, 4-5, 6, 7-8, and 9 had distinctly very low(0%-20%), low(21%-40%), intermediate(41%-60%), high(61%-80%), and very high(81%-100%) risks of LN involvement, respectively. The developed RPRS showed good discrimination and satisfactory calibration (C-index: 0.785, 95% confidence interval(95% CI):0.780-0.790)Additionally, RPRS outperformed the clinicopathologic-based characteristics model with net reclassification index(NRI) of 0.711(95% CI: 0.555-0.867).Conclusions: The novel clinical scoring system developed as RPRS can serve as an easy-to-use tool to facilitate the preoperatively individualized prediction of LN metastasis in patients with resectable NSCLC. This stratification of patients according to their LN status may provide a basis for individualized treatment.

文摘BACKGROUND Primary liver cancer is a globally prevalent malignancy,with China accounting for approximately 55%of new cases,and is linked to hepatitis B,aflatoxin,and cirrhosis.Its rupture with hemorrhagic shock is a lethal complication with high mortality,and traditional triage struggles with timely risk stratification,necessitating better tools,such as the integrated shock index(SI)-early warning score(EWS).AIM To study and analyze the combined effect of the SI and EWS in primary liver cancer patients with ruptured hemorrhage and shock.METHODS In total,118 patients who visited the Emergency Department of Nantong Third People's Hospital from January 2023 to December 2024 were selected and randomly divided into a control group(59 patients who received routine emergency treatment)and an observation group(59 patients who received condition assessment and intervention by combining the SI and EWS based on routine emergency treatment).The clinical treatment outcomes,respiratory function indicators,serological indicators,complications,and satisfaction with emergency intervention before and after the emergency intervention were compared between the two groups.RESULTS The emergency,triage,waiting,and hemostasis times,as well as hospital stay were shorter in the observation group than in the control group(P<0.05).After 48 hours of emergency intervention,blood oxygen saturation and partial pressure of oxygen in the observation group were higher than those in the control group(P<0.05).Seven days after emergency intervention,the hemoglobin,prealbumin,and albumin levels were higher in the observation group than in the control group(P<0.05).The complication rate in the observation group was 3.39%,lower than that in the control group(13.56%;P<0.05).Satisfaction with emergency intervention in the observation group was 94.92%,higher than 83.05%in the control group(P<0.05).CONCLUSION The combined application of the SI and EWS in patients with primary liver cancer rupture,hemorrhage,and shock can significantly shorten emergency treatment time,improve respiratory function and serological indicators,reduce the incidence of complications,and enhance patient satisfaction with emergency interventions,with higher clinical treatment efficiency and quality.Therefore,it is worthy of promotion and application.

文摘AIM: To implement a quick and simple test- rapid assessment faecal incontinence score(RAFIS) and show its reliability and validity.METHODS: From March 2008 through March 2010, we evaluated a total of 261 consecutive patients, including 53 patients with faecal incontinence. Demographic and comorbidity information was collected. In a single visit, patients were administered the RAFIS. The results obtained with the new score were compared with those of both Wexner score and faecal incontinence quality of life scale(FIQL) questionnaire. The patient withoutinfluence of the surgeon completed the test. The role of surgeon was explaining the meaning of each section and how he had to fill. Reliability of the RAFIS score was measured using intra-observer agreement and Cronbach's alpha(internal consistency) coefficient. Multivariate analysis of the main components within the different scores was performed in order to determine whether all the scores measured the same factor and to conclude whether the information could be encompassed in a single factor. A sample size of 50 patients with faecal incontinence was estimated to be enough to detect a correlation of 0.55 or better at 5% level of significance with 80% power.RESULTS: We analysed the results obtained by 53 consecutive patients with faecal incontinence(median age 61.55 ± 12.49 years) in the three scoring systems. A total of 208 healthy volunteers(median age 58.41 ± 18.41 years) without faecal incontinence were included in the study as negative controls. Pearson's correlation coefficient between "state" and "leaks" was excellent(r = 0.92, P < 0.005). Internal consistency in the comparison of "state" and "leaks" yielded also excellent correlation(Cronbach's α = 0.93). Results in each score were compared using regression analysis and a correlation value of r = 0.98 was obtained with Wexner score. As regards FIQL questionnaire, the values of "r " for the different subscales of the questionnaire were: "lifestyle" r =-0.87, "coping/behaviour" r =-0.91, "depression" r =-0.36 and "embarrassment" r =-0.90,(P < 0.01). A multivariate analysis showed that all the scoring systems measured the same factor. A single factor may explain 80.84% of the variability of FI, so all the scoring systems measure the same factor. Patient's continence improves when RAFIS and Jorge-Wexner scores show low values and when the values obtained in the FIQL questionnaire are high.CONCLUSION: RAFIS is a valid and reliable tool to assess Faecal Incontinence.

文摘BACKGROUND Hepatic encephalopathy(HE)remains an enormous challenge in patients who undergo transjugular intrahepatic portosystemic shunt(TIPS)implantation.The preoperative indocyanine green retention rate at 15 min(ICG-R15),as one of the liver function assessment tools,has been developed as a prognostic indicator in patients undergoing surgery,but there are limited data on its role in TIPS.AIM To determine whether the ICG-R15 can be used for prediction of post-TIPS HE in decompensated cirrhosis patients with portal hypertension(PHT)and compare the clinical value of ICG-R15,Child-Pugh score(CPS),and model for end-stage liver disease(MELD)score in predicting post-TIPS HE with PHT.METHODS This retrospective study included 195 patients with PHT who underwent elective TIPS at Beijing Shijitan Hospital from January 2018 to June 2019.All patients underwent the ICG-R15 test,CPS evaluation,and MELD scoring 1 wk before TIPS.According to whether they developed HE or not,the patients were divided into two groups:HE group and non-HE group.The prediction of one-year post-TIPS HE by ICG-R15,CPS and MELD score was evaluated by the areas under the receiver operating characteristic curves(AUCs).RESULTS A total of 195 patients with portal hypertension were included and 23%(45/195)of the patients developed post-TIPS HE.The ICG-R15 was identified as an independent predictor of post-TIPS HE.The AUCs for the ICG-R15,CPS,and MELD score for predicting post-TIPS HE were 0.664(95%confidence interval[CI]:0.557-0.743,P=0.0046),0.596(95%CI:0.508-0.679,P=0.087),and 0.641(95%CI:0.554-0.721,P=0.021),respectively.The non-parametric approach(Delong-Delong&Clarke-Pearson)showed that there was statistical significance in pairwise comparison between AUCs of ICG-R15 and MELD score(P=0.0229).CONCLUSION The ICG-R15 has appreciated clinical value for predicting the occurrence of post-TIPS HE and is a choice for evaluating the prognosis of patients undergoing TIPS.
文摘Eastern Cooperative Oncology Group(ECOG)performance status and Gleason score are commonly investigated factors for overall survival(OS)in men with castration-resistant prostate cancer(CRPC).However,there is a lack of consistency regarding their prognostic or predictive value for OS.Therefore,we performed this meta-analysis to assess the associations of ECOG performance status and Gleason score with OS in CRPC patients and compare the two markers in patients under different treatment regimens or with different chemotherapy histories.A systematic literature review of monotherapy studies in CRPC patients was conducted in the PubMed database until May 2019.The data from 8247 patients in 34 studies,including clinical trials and real-world data,were included in our meta-analysis.Of these,twenty studies reported multivariate results and were included in our main analysis.CRPC patients with higher ECOG performance statuses(≥2)had a significantly increased mortality risk than those with lower ECOG performance statuses(<2),hazard ratio(HR):2.10,95%confidence interval(CI):1.68-2.62,and P<0.001.The synthesized HR of OS stratified by Gleason score was 1.01,with a 95%CI of 0.62-1.67(Gleason score≥8 vs<8).Subgroup analysis showed that there was no significant difference in pooled HRs for patients administered taxane chemotherapy(docetaxel and cabazitaxel)and androgen-targeting therapy(abiraterone acetate and enzalutamide)or for patients with different chemotherapy histories.ECOG performance status was identified as a significant prognostic factor in CRPC patients,while Gleason score showed a weak prognostic value for OS based on the available data in our meta-analysis.

文摘AIM To establish minimum clinically important difference(MCID) for measurements in an orthopaedic patient population with joint disorders.METHODS Adult patients aged 18 years and older seeking care for joint conditions at an orthopaedic clinic took the Patient-Reported Outcomes Measurement Information System Physical Function(PROMIS~? PF) computerized adaptive test(CAT), hip disability and osteoarthritis outcome score for joint reconstruction(HOOS JR), and the knee injury and osteoarthritis outcome score for joint reconstruction(KOOS JR) from February 2014 to April 2017. MCIDs were calculated using anchorbased and distribution-based methods. Patient reports of meaningful change in function since their first clinic encounter were used as an anchor.RESULTS There were 2226 patients who participated with a mean age of 61.16(SD = 12.84) years, 41.6% male, and 89.7% Caucasian. Mean change ranged from 7.29 to 8.41 for the PROMIS~? PF CAT, from 14.81 to 19.68 for the HOOS JR, and from 14.51 to 18.85 for the KOOS JR. ROC cut-offs ranged from 1.97-8.18 for the PF CAT, 6.33-43.36 for the HOOS JR, and 2.21-8.16 for the KOOS JR. Distribution-based methods estimated MCID values ranging from 2.45 to 21.55 for the PROMIS~? PF CAT; from 3.90 to 43.61 for the HOOS JR, and from 3.98 to 40.67 for the KOOS JR. The median MCID value in the range was similar to the mean change score for each measure and was 7.9 for the PF CAT, 18.0 for the HOOS JR, and 15.1 for the KOOS JR.CONCLUSION This is the first comprehensive study providing a wide range of MCIDs for the PROMIS? PF, HOOS JR, and KOOS JR in orthopaedic patients with joint ailments.
