文摘BACKGROUND Anastomotic leakage(AL)is a serious complication following rectal cancer surgery and is associated with increased recurrence,mortality,extended hospital stays,and delayed chemotherapy.The Onodera prognostic nutritional index(OPNI)and inflammation-related biomarkers,such as the neutrophil-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR),have been studied in the context of cancer prognosis,but their combined efficacy in predicting AL remains unclear.AIM To investigate the relationships between AL and these markers and developed a predictive model for AL.METHODS A retrospective cohort study analyzed the outcomes of 434 patients who had undergone surgery for rectal cancer at a tertiary cancer center from 2016 to 2023.The patients were divided into two groups on the basis of the occurrence of AL:One group consisted of patients who experienced AL(n=49),and the other group did not(n=385).The investigation applied logistic regression to develop a risk prediction model utilizing clinical,pathological,and laboratory data.The efficacy of this model was then evaluated through receiver operating characteristic curve analysis.RESULTS In the present study,11.28%of the participants(49 out of 434 participants)suffered from AL.Multivariate analysis revealed that preoperative levels of the OPNI,NLR,and PLR emerged as independent risk factors for AL,with odds ratios of 0.705(95%CI:0.641-0.775,P=0.012),1.628(95%CI:1.221-2.172,P=0.024),and 0.994(95%CI:0.989-0.999,P=0.031),respectively.These findings suggest that these biomarkers could effectively predict AL risk.Furthermore,the proposed predictive model has superior discriminative ability,as demonstrated by an area under the curve of 0.910,a sensitivity of 0.898,and a specificity of 0.826,reflecting its high level of accuracy.CONCLUSION The risk of AL in rectal cancer surgery patients can be effectively predicted by assessing the preoperative levels of serum nutritional biomarkers and inflammatory indicators,emphasizing their importance in the preoperative evaluation process.
文摘BACKGROUND Acute liver failure(ALF)is a life-threatening multisystemic condition with high short-term mortality.With the growing prevalence of obesity and metabolic syndrome,it is important to investigate the clinical implications of high body mass index(BMI)on survival outcomes in ALF.AIM To explore the impact of overweight and obesity on the clinical outcomes of patients with ALF.METHODS A retrospective observational cohort study was conducted involving patients with ALF admitted to the Johns Hopkins Health System between January 1,2000 and May 1,2020.We performed Cox proportional hazards regression to identify outcomes,including the need for liver transplantation(LT)or all-cause mortality.RESULTS A total of 196 patients were included,the median age was 43.5 years,63.3%were female,and 59.7%were of Caucasian ethnicity.Acetaminophen-induced ALF was the most common etiology(45%).The mean BMI was significantly greater among patients who underwent LT or died(29.64 kg/m^(2)vs 26.59 kg/m^(2),P=0.008)than among survivors.Patients with overweight and obesity had a higher risk of all-cause mortality or need for LT by 2.22-fold(95%CI:1.30-3.78)and 2.04-fold(95%CI:1.29-3.39),respectively.Elevated BMI was associated with renal failure and higher grades of hepatic encephalopathy.Derangements in serologic markers,including alanine transaminase,lactate,and ammonia,were associated with a mortality risk or need for LT.CONCLUSION In this large,retrospective study,with a diverse cohort of United States patients,Overweight and obese were independently associated with an increased risk of all-cause mortality or need for LT.This work highlights the importance of closely monitoring ALF patients who are overweight or obese for adverse complications and measures to improve outcomes in this vulnerable patient population.

文摘ACKGROUND The hemoglobin glycation index(HGI)represents the discrepancy between the glucose management indicator(GMI)based on mean blood glucose levels and laboratory values of glycated hemoglobin(HbA1c).The HGI is a promising indicator for identifying individuals with excessive glycosylation,facilitating personalized evaluation and prediction of diabetic complications.However,the factors influencing the HGI in patients with type 1 diabetes(T1D)remain unclear.Autoimmune destruction of pancreaticβcells is central in T1D pathogenesis,yet insulin resistance can also be a feature of patients with T1D and their coexistence is called“double diabetes”(DD).However,knowledge regarding the relationship between DD features and the HGI in T1D is limited.AIM To assess the association between the HGI and DD features in adults with T1D.METHODS A total of 83 patients with T1D were recruited for this cross-sectional study.Laboratory HbA1c and GMI from continuous glucose monitoring data were collected to calculate the HGI.DD features included a family history of type 2 diabetes,overweight/obesity/central adiposity,hypertension,atherogenic dyslipidemia,an abnormal percentage of body fat(PBF)and/or visceral fat area(VFA)and decreased estimated insulin sensitivity.Skin autofluorescence of advanced glycation end products(SAF-AGEs),diabetic complications,and DD features were assessed,and their association with the HGI was analyzed.RESULTS A discrepancy was observed between HbA1c and GMI among patients with T1D and DD.A higher HGI was associated with an increased number of SAF-AGEs and a higher prevalence of diabetic microangiopathy(P=0.030),particularly retinopathy(P=0.031).Patients with three or more DD features exhibited an eight-fold increased risk of having a high HGI,compared with those without DD features(adjusted odds ratio=8.12;95%confidence interval:1.52-43.47).Specifically,an elevated PBF and/or VFA and decreased estimated insulin sensitivity were associated with high HGI.Regression analysis identified estimated insulin sensitivity and VFA as factors independently associated with HGI.CONCLUSION In patients with T1D,DD features are associated with a higher HGI,which represents a trend toward excessive glycosylation and is associated with a higher prevalence of chronic diabetic complications.

文摘BACKGROUND Gastric cancer(GC)is the fifth most common cancer and the third leading cause of cancer-related deaths in China.Many patients with GC frequently experience symptoms related to the disease,including anorexia,nausea,vomiting,and other discomforts,and often suffer from malnutrition,which in turn negatively affects perioperative safety,prognosis,and the effectiveness of adjuvant therapeutic measures.Consequently,some nutritional indicators such as nutritional risk index(NRI),prognostic nutritional index(PNI),and systemic immune-inflammatorynutritional index(SIINI)can be used as predictors of the prognosis of GC patients.AIM To examine the prognostic significance of PNI,NRI,and SIINI in postoperative patients with GC.METHODS A retrospective analysis was conducted on the clinical data of patients with GC who underwent surgical treatment at the Guangxi Medical University Cancer Hospital between January 2010 and December 2018.The area under the receiver operating characteristic(ROC)curve was assessed using ROC curve analysis,and the optimal cutoff values for NRI,PNI,and SIINI were identified using the You-Review-HTMLden index.Survival analysis was performed using the Kaplan-Meier method.In addition,univariate and multivariate analyses were conducted using the Cox proportional hazards regression model.RESULTS This study included a total of 803 patients.ROC curves were used to evaluate the prognostic ability of NRI,PNI,and SIINI.The results revealed that SIINI had superior predictive accuracy.Survival analysis indicated that patients with GC in the low SIINI group had a significantly better survival rate than those in the high SIINI group(P<0.05).Univariate analysis identified NRI[hazard ratio(HR)=0.68,95%confidence interval(CI):0.52-0.89,P=0.05],PNI(HR=0.60,95%CI:0.46-0.79,P<0.001),and SIINI(HR=2.10,95%CI:1.64-2.69,P<0.001)as prognostic risk factors for patients with GC.However,multifactorial analysis indicated that SIINI was an independent risk factor for the prognosis of patients with GC(HR=1.65,95%CI:1.26-2.16,P<0.001).CONCLUSION Analysis of clinical retrospective data revealed that SIINI is a valuable indicator for predicting the prognosis of patients with GC.Compared with NRI and PNI,SIINI may offer greater application for prognostic assessment.

文摘The Dst index has been commonly used to measure the geomagnetic effectiveness of magnetic storm events for several decades.Based on Burton’s empirical Dst model and the global magneto-hydrodynamic(MHD)simulation of Earth’s magnetosphere,here we proposed a semi-empirical model to forecast the Dst index during geomagnetic storms.In this model,the ring current contribution to the Dst index is derived from Burton’s model,while the contributions from other current systems are obtained from the global MHD simulation.In order to verify the model accuracy,a number of recent magnetic storm events are tested and the simulated Dst index is compared with the observation through the correlation coefficient(CC),prediction efficiency(PE),root mean square error(RMSE)and central root mean square error(CRMSE).The results indicate that,in the context of moderate and intense geomagnetic storm events,the semi-empirical model performs well in global MHD simulations,showing relatively higher CC and PE,and lower RMSE and CRMSE compared to those from the empirical model.Compared with the physics-based ring current models,this model inherits the advantage of fast processing from the empirical model,and easy implementation in a global MHD model of Earth’s magnetosphere.Therefore,it is suitable for the Dst estimation under a context of a global MHD simulation.
文摘Extreme weather events,such as floods and droughts,are expected to rise significantly worldwide as a result of climate change.Investigating future drought patterns is therefore a key approach for elaborating anticipatory water resources management responses to climate change.In this paper,future meteorological drought conditions are investigated based on the SPEI(Standardised Precipitation Evapotranspiration Index).This study makes use of observed and projected data.The simulated data were retrieved from the CMIP6(Coupled Model Intercomparison Project Phase 6)over the period 2025-2050,and the Delta change method was adopted to remove the bias in the dataset.Then SPEI at various scales has been estimated under four future scenarios(SSP1-2.6,SSP2-4.5,SSP3-7.0 and SSP5-8.5).The trend analysis of the projected SPEI was performed at p<0.05 using the MMK(Modified Mann-Kendall)test in order to detect the statistically significant trend of the drought against the null hypothesis of no trend.Results show large variability in the magnitude of drought in the past and future.Based on SPEI at 24 months accumulation,the result shows that under SSP1-2.6,the basin will experience a wet period during the first decade(SPEI=0.60),the second decade will be dry(SPEI24=-0.43).The remaining years will be also dry(SPEI=-0.34).Under SSP2-4.5,SSP3-7.0 and SSP5-8.5 scenarios,the district will experience a wet period during the first two decades with SPEI ranging from 0.38 to 0.59.This wet period will be followed by a dry period under these scenarios ranging from-0.14 to-0.06.Overall,under SSPs scenarios,two main periods characterized by a rainfall recovery spanning from followed by a moderately prolonged drought are identified within the study area.The findings of this study may provide valuable information for developing proactive measures to reduce water insecurity in Fada N’Gourma through effective drought mitigation.
文摘This editorial comments on the study by Tao et al,emphasizing the scalable diagnostic tool for metabolic dysfunction-associated steatotic liver disease(MASLD)in type 2 diabetes mellitus(T2DM).Classical indices such as the fatty liver index(FLI),hepatic steatosis index(HSI),and non-alcoholic fatty liver disease-liver fat score have provided valuable insights.Still,their predictive accuracy often varies across populations and clinical settings.In Western cohorts,FLI and HSI are widely applied,yet they depend heavily on anthropometric or categorical variables,which limits their sensitivity in Asian populations.The Zhejiang University index(ZJU index),developed in China,integrates fasting glucose,triglycerides,hepatic enzyme ratios,and body mass index into a composite score of insulin resistance.Recent studies show that the ZJU index outperforms FLI and HSI in predicting MASLD among Chinese patients,particularly those with T2DM,where it demonstrates a nonlinear association with disease risk and identifies a critical threshold of 38.87.The ZJU index links to conditions like sarcopenia,sleep apnea,and gallstones,showing its versatility in metabolic health.This editorial compares its performance with other indices and emphasizes the ZJU index as a nextgeneration tool for MASLD risk stratification globally.

文摘BACKGROUND Gastric cancer,a globally prevalent malignant tumor,continues to exhibit high incidence and mortality rates.Although radical gastrectomy remains the primary treatment for this disease,postoperative complications frequently arise,negatively impacting short-term recovery and significantly reducing patients’quality of life.In this context,accurately predicting the risk of postoperative recurrence and metastasis,coupled with targeted interventions,could substantially improve patient outcomes.The C-reactive protein-triglyceride-glucose index(CTI),a composite biomarker that integrates metabolic disturbances and systemic inflammation,has garnered increasing attention in oncology.The prognostic nutritional index(PNI),a composite measure based on serum albumin and peripheral blood lymphocyte count,is used to evaluate both the nutritional status and systemic immune function of patients.In recent years,both the CTI and PNI have demonstrated significant prognostic value in predicting tumor outcomes,assessing treatment responses,and formulating personalized treatment strategies.AIM To investigate whether the combined inflammation and insulin resistance marker,the CTI,can serve as a prognostic indicator for patients undergoing radical gastrectomy for gastric cancer.Additionally,it seeks to develop a predictive model by incorporating the PNI alongside CTI.METHODS This retrospective study included a total of 300 patients who underwent radical gastrectomy.The patients were classified into high and low CTI groups based on their CTI index.Cox proportional hazards regression analysis was performed to identify independent prognostic factors influencing overall survival(OS)and disease-free survival(DFS),and two nomogram models were developed.RESULTS Of the included patients,131 had a high CTI and 169 had a low CTI.The DFS period of the low CTI group was significantly longer than that of the high CTI group.The number of postoperative adjuvant treatments,T stage,N stage,CTI,and PNI were identified as independent prognostic factors for DFS.The hazard ratio for CTI was 2.07(95%confidence interval:1.36-3.17,P<0.001).In terms of OS,the OS period of the low CTI group was significantly longer than that of the high CTI group.Whether adjuvant treatment was administered,T stage,CTI,and PNI were independent prognostic factors for OS.The hazard ratio for CTI was 2.47(95%confidence interval:1.44-4.23,P=0.001).The nomogram models for OS and DFS further emphasized the importance of CTI as a key predictor of patient prognosis.CONCLUSION CTI is a long-term prognostic indicator for the outcome of radical gastrectomy for gastric cancer.Patients with lower CTI values have a better prognosis.The prediction models constructed by combining CTI with PNI has good predictive ability for DFS and OS after radical gastrectomy.

文摘Based on optofluidics and whispering gallery mode(WGM)theory,here an optofluidic refractive index sensor with microtube-coupled suspended core fiber(SCF)is proposed.It solves the issues of general sensors with microcavity-coupled fiber taper such as too fragile,unstable performance due to open coupling,poor portability and repeatability,while overcoming the poor performance of low refractive index sensing in general full-package fiber sensors.The sensor only needs a very small amount of liquid sample(about 1.8 nL).The proposed sensor combines the excellent performance of full package,optofluidics and WGM resonator.The resonant characteristics and sensing performance of the sensor are analyzed and discussed by the theoretical simulation.The simulation results indicate that the sensor has a wide refractive index sensing range(1.330-1.700)and good performance.The resonance wavelength shift has a good linear relationship with the liquid refractive index variation.In the low refractive index region,the sensitivity is 222.5-247.5 nm/RIU,Q-factor is 1.03×10^(3) and the detection limit is 3.64×10^(-4) RIU.In the medium and high refractive index regions,the sensitivity is 564.4-846.2 nm/RIU,Q-factor is up to 8.62×10^(4),and the detection limit can be as low as 1.29×10^(-6) RIU.The sensor exhibits a high sensitivity,a high Q-factor and a very low detection limit.
