The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.展开更多

C reactive protein (CRP) has linked with long-term risk of recurrent cardiovascular events or death. Albumin, in contrast to CRP known as a negative acute-phase protein. Thus a newly introduced marker assessed relation of CRP to albumin ratio (CAR), which may provide better results than the use of either marker alone. The aim of the study is to assess the association of C-reactive protein to albumin ratio (CAR) with in-hospital short-term major adverse cardiac events (MACEs) in acute coronary syndrome (ACS) patients. Patients & Methods: A multi-centers prospective cohort study was conducted at coronary intensive care units (CICU) in Baghdad during the period from March to October 2021 that included a total of 132 patients who were diagnosed as a case of ACS. They were assessed for major adverse cardiac events (MACEs) like cardiogenic shock, arrhythmias, post-MI angina, and acute heart failure while inside the ward, in addition to need for early interventional therapeutic approach in relation to (CAR) immediately at time of admission to hospital. Results: High values of CAR, whether using hs-CRP or CRP, were identified as an independent predictor for in-hospital MACEs (P value Conclusion: The CAR was independently correlated with in-hospital short-term MACEs and can be used for risk stratification in patients with ACS.展开更多

Methods:Clinical data regarding the PBL and tumor tissues were obtained at The First Hospital of Jilin University between February 2009 and March 2017.We detected indices of glucose and lipid metabolism,classified and counted PBL lymphocytes using flow cy-tometry,determined the tumor-infiltrating lymphocytes by quantitative immunofluorescence,and analyzed the T-cell receptor(TCR)rep-ertoire by high-throughput sequencing of the TCR β-chain.The correlations between ALB and metabolic immune indices were analyzed by t tests and Pearson chi-square test. Results:A total of 211 enrolled NSCLC patients were divided into a relatively high-ALB group(>41.75 g/L,n = 56)and a low-ALB group(≤41.75 g/L,n = 155);patients with high ALB had lower Treg cells(P<0.05)and more CD8+ cytotoxic T cells in the PBL(P<0.01)and a higher proportion of stromal CD8+ tumor-infiltrating lymphocytes(P = 0.047)than patients with low ALB.High ALB was also significantly related to more diversity in the TCR repertoire(P = 0.0021,r2 = 0.5481).Moreover,ALB was identified as an in-dependent prognostic factor based on a multivariate Cox regression analysis(P = 0.032;hazard ratio(HR)= 1.804;95%confidence interval(CI)= 1.035-3.146).The median overall survival in patients with low ALB vs high ALB was 28.2 vs 42.2 months(P=0.0142),respectively.Among patients with nonmetastatic NSCLC(stage Ⅰ-Ⅲ),there was a higher incidence of distant metastasis in the low-ALB group than that in the high-ALB group(41.3%and 22.2%,P=0.043).A low ALB also had a strong association with a higher risk for disease progression(P<0.001)and death(P<0.01;HR = 0.555;95%CI= 0.312-0.988). Conclusions:Albumin could affect the host immunity,and high ALB predicted a reduced risk of distant metastasis and improved the prognosis in NSCLC patients.展开更多

文摘Epicatechin(EC)was used in this study to antagonize the cognitive dysfunction caused by lead(Pb)exposure in mice.Eight-week-old male Kunming mice were treated with PbCl_(2)(20 mg/kg)and/or EC(50 mg/kg)by gavage administration for 4 weeks.Morris water maze test showed that EC could improve memory dysfunction induced by Pb.EC antagonized Ca^(2+)overload,activated Nrf2 signaling pathway and reduced the accumulation of Pb in the brain and serum,which suggested that EC might alter Pb distribution in mice.In vitro,spectroscopic analysis,potentiometric titration and docking studies were applied to inquiry into the interaction between bovine serum albumin(BSA)and Pb^(2+)in presence or absence of EC.EC was proved to chelate Pb^(2+)and reduced the interaction between BSA and Pb^(2+).In summary,EC might protect Pb-induced cognitive impairment by activating Nrf2 signaling pathway,and suppressing Pb accumulation via interference on the binding of Pb to albumin.

文摘BACKGROUND Gastric cancer has a high incidence and fatality rate,and surgery is the preferred course of treatment.Nonetheless,patient survival rates are still low,and the incidence of major postoperative complications cannot be disregarded.The systemic inflammatory response,nutritional level,and coagulation status are key factors affecting the postoperative recovery and prognosis of gastric cancer patients.The systemic inflammatory response index(SIRI)and the albumin fibrinogen ratio(AFR)are two valuable comprehensive indicators of the severity and prognosis of systemic inflammation in various medical conditions.AIM To assess the clinical importance and prognostic significance of the SIRI scores and the AFR on early postoperative outcomes in patients undergoing radical gastric cancer surgery.METHODS We conducted a retrospective analysis of the clinicopathological characteristics and relevant laboratory indices of 568 gastric cancer patients from January 2018 to December 2019.We calculated and compared two indicators of inflammation and then examined the diagnostic ability of combined SIRI and AFR values for serious early postoperative complications.We scored the patients and categorized them into three groups based on their SIRI and AFR levels.COX analysis was used to compare the three groups of patients the prognostic value of various preoperative SIRI-AFR scores for 5-year overall survival(OS)and disease-free survival(DFS).RESULTS SIRI-AFR scores were an independent risk factor for prognosis[OS:P=0.004;hazards ratio(HR)=3.134;DFS:P<0.001;HR=3.543]and had the highest diagnostic power(area under the curve:0.779;95%confidence interval:0.737-0.820)for early serious complications in patients with gastric cancer.The tumor-node-metastasis stage(P=0.001),perioperative transfusion(P=0.044),positive carcinoembryonic antigen(P=0.014)findings,and major postoperative complications(P=0.011)were factors associated with prognosis.CONCLUSION Preoperative SIRI and AFR values were significantly associated with early postoperative survival and the occurrence of severe complications in gastric cancer patients.
文摘BACKGROUND Gestational diabetes mellitus(GDM)is characterized by glucose intolerance that is first diagnosed during pregnancy,making it the most common complication associated with this period.Early detection and targeted treatment of GDM can minimize foetal exposure to maternal hyperglycaemia and subsequently reduce the associated adverse pregnancy outcomes.Previous studies have inconsistently suggested that the level of glycated albumin(GA)might predict GDM.AIM To review and synthesize existing evidence to evaluate the relationship between GA levels and the development of GDM.METHODS We sought to compare GA levels between GDM and control groups in this metaanalysis by systematically searching the Web of Science,PubMed,Cochrane Library,and Embase databases for articles published up to June 2023.The analysis utilized the weighted mean difference(WMD)as the primary metric.The data were meticulously extracted,and the quality of the included studies was assessed.Additionally,we conducted a subgroup analysis based on study region and sample size.We assessed heterogeneity using I2 statistics and evaluated publication bias through funnel plots.Additionally,trim-and-fill analysis was employed to detect and address any potential publication bias.RESULTS The meta-analysis included a total of 11 studies involving 5477 participants,comprising 1900 patients with GDM and 3577 control individuals.The synthesized results revealed a notable correlation between elevated GA levels and increased susceptibility to GDM.The calculated WMD was 0.42,with a 95%confidence interval(95%CI)ranging from 0.11 to 0.74,yielding a P value less than 0.001.Concerning specific GA levels,the mean GA level in the GDM group was 12.6,while for the control group,it was lower,at 11.6.This discrepancy underscores the potential of GA as a biomarker for assessing GDM risk.Moreover,we explored the levels of glycated haemoglobin(HbA1c)in both cohorts.The WMD for HbA1c was 0.19,with a 95%CI ranging from 0.15 to 0.22 and a P value less than 0.001.This observation suggested that both GA and HbA1c levels were elevated in individuals in the GDM group compared to those in the control group.CONCLUSION Our meta-analysis revealed a substantial correlation between elevated GA levels and increased GDM risk.Furthermore,our findings revealed elevated levels of HbA1c in GDM patients,emphasizing the significance of monitoring both GA and HbA1c levels for early GDM detection and effective management.

文摘BACKGROUND Over the years,programmed cell death-1(PD-1)inhibitors have been routinely used for hepatocellular carcinoma(HCC)treatment and yielded improved survival outcomes.Nonetheless,significant heterogeneity surrounds the outcomes of most studies.Therefore,it is critical to search for biomarkers that predict the efficacy of PD-1 inhibitors in patients with HCC.AIM To investigate the role of the C-reactive protein to albumin ratio(CAR)in evaluating the efficacy of PD-1 inhibitors for HCC.METHODS The clinical data of 160 patients with HCC treated with PD-1 inhibitors from January 2018 to November 2022 at the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed.RESULTS The optimal cut-off value for CAR based on progression-free survival(PFS)was determined to be 1.20 using x-tile software.Cox proportional risk model was used to determine the factors affecting prognosis.Eastern Cooperative Oncology Group performance status[hazard ratio(HR)=1.754,95%confidence interval(95%CI)=1.045-2.944,P=0.033],CAR(HR=2.118,95%CI=1.057-4.243,P=0.034)and tumor number(HR=2.932,95%CI=1.246-6.897,P=0.014)were independent prognostic factors for overall survival.CAR(HR=2.730,95%CI=1.502-4.961,P=0.001),tumor number(HR=1.584,95%CI=1.003-2.500,P=0.048)and neutrophil to lymphocyte ratio(HR=1.120,95%CI=1.022-1.228,P=0.015)were independent prognostic factors for PFS.Two nomograms were constructed based on independent prognostic factors.The C-index index and calibration plots confirmed that the nomogram is a reliable risk prediction tool.The ROC curve and decision curve analysis confirmed that the nomogram has a good predictive effect as well as a net clinical benefit.CONCLUSION Overall,we reveal that the CAR is a potential predictor of short-and long-term prognosis in patients with HCC treated with PD-1 inhibitors.If further verified,CAR-based nomogram may increase the number of markers that predict individualized prognosis.
文摘Gestational diabetes mellitus is the most common endocrine disorder in pregnancy and a cause of maternal and fetal morbidities and mortalities. The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.

文摘Objective:To identify the association between serum albumin levels and disease severity among adult patients with dengue in China's Mainland.Methods:This retrospective cohort study analyzed the data of adult patients(aged≥18 years)hospitalized with laboratory-confirmed dengue in a tertiary center for infectious diseases from 2013 to 2019 in China's Mainland.Serum albumin levels were estimated and compared between patients with severe dengue and non-severe dengue.Additionally,the association between serum albumin levels and severe dengue was evaluated using a generalized linear model[relative risks(RR)].Multivariate logistic regression analysis was performed to identify the potential predictors of severe dengue.Results:Overall,1568 patients were included in this study.Of these patients,34(2.17%)developed severe dengue.The median serum albumin levels were significantly lower in patients with severe dengue than that in those with non-severe dengue(33 g/L vs.37 g/L,P<0.001).After adjustment for age,sex,and comorbidities,hypoalbuminemia(RR 4.877,95%CI 2.193-11.461,P<0.001)was found to be a predictor of severe dengue.Serum albumin levels(OR 1.303,95%CI 1.161-1.462,P<0.001)and age(OR 1.038,95%CI 1.017-1.061,P<0.001)were significant risk factors for severe dengue.The area under the curve for serum albumin levels to distinguish severe dengue was 0.787.Conclusions:Lower serum albumin levels were significantly associated with disease severity in adult patients with dengue.Hypoalbuminemia on admission resulted in at least a four-fold increased risk of severe dengue.
文摘BACKGROUND The hemoglobin,albumin,lymphocyte,and platelet(HALP)score,derived from a composite evaluation of markers reflecting the tumor-inflammation relationship and nutritional status,has been substantiated as a noteworthy prognostic determinant for diverse malignancies.AIM To investigate how the HALP score relates to prognosis in patients with metastatic gastric cancer.METHODS The cutoff values for the HALP score,neutrophil/lymphocyte ratio,and platelet/lymphocyte ratio were determined using receiver operating characteristic analysis.Low HALP scores were defined as those less than 24.79 and high HALP scores as those greater than 24.79.RESULTS The study cohort comprised 147 patients and 110 of them(74.8%)were male.The patients'median age was 63(22-89)years.The median overall survival was significantly superior in the patients with high HALP scores than in those with low HALP scores(10.4 mo vs 7.5 mo,respectively;P<0.001)CONCLUSION The HALP score was found to be a prognostic factor in patients with metastatic gastric cancer.
文摘BACKGROUND Perforated peptic ulcer(PPU)is a common emergency surgical condition and a significant cause of morbidity and mortality worldwide.While advances in surgical techniques have improved outcomes for patients with PPU,many factors still affect postoperative hospital stay and overall prognosis.One potential factor is the serum albumin(SA)level,a widely utilized marker of nutritional status that has been associated with length of stay and complications in various surgical procedures.AIM To clarify the correlation of SA level on postoperative day 2 with hospital length of stay(HLOS)in patients undergoing emergency surgery for perforated peptic ulcer(PPU).METHODS We retrospectively collected and analyzed clinical baseline data,including blood routine and SA levels,of patients who underwent emergency PPU surgery and postoperative treatment at the Lingnan Hospital,the Third Affiliated Hospital of Sun Yat-sen University between December 2012 and September 2021.Patients were grouped according to HLOS with 7 d as the cut-off value,and relevant indicators were analyzed using SPSS 26.0.RESULTS Of the 37 patients undergoing emergency surgery for PPU referred to our department,33 had gastric and 4 had duodenal ulcer perforation.The median HLOS was 10 d.There were 8 patients in the≤7-d group(median HLOS:7 d)and 29 patients in the>7-d group(median HLOS:10 d).The≤7-d group had markedly higher SA on postoperative day 2 than the>7-d group(37.7 g/L vs 32.6g/L;P<0.05).The SA level on postoperative day 2 was a protective factor for patients with HLOS>7 d(Odds ratio=0.629,P=0.015).The cut-off of SA on postoperative day 2 was 30.6g/L,with an area under the curve of 0.86 and a negative predictive value of 100%for the prediction of HLOS≤7 d.CONCLUSION The SA level on postoperative day 2 was associated with the HLOS in patients undergoing emergency surgery for PPU.The pre-and post-operative albumin levels should be monitored,and infusion of human SA should be considered in a timely manner.

文摘Objective C-reactive protein(CRP)/albumin ratio(CAR)is a new inflammation-based index for predicting the prognosis of various diseases.The CAR determined on admission may help to predict the prognostic value of multiple trauma patients.Methods A total of 264 adult patients with severe multiple trauma were included for the present retrospective study,together with the collection of relevant clinical and laboratory data.CAR,CRP,albumin,shock index and ISS were incorporated into the prognostic model,and the receiver operating characteristic(ROC)curve was drawn.Then,the shock index for patients with different levels of CAR was analyzed.Finally,univariate and multivariate logistic regression analyses were performed to identify the independent risk factors for the 28-day mortality of multiple trauma patients.Results A total of 36 patients had poor survival outcomes,and the mortality rate reached 13.6%.Furthermore,after analyzing the shock index for patients with different levels of CAR,it was revealed that the shock index was significantly higher when CAR was≥4,when compared to CAR<2 and 2≤CAR<4,in multiple trauma patients.The multivariate logistic analysis helped to identify the independent association between the variables CAR(P=0.029)and shock index(P=0.019),and the 28-day mortality of multiple trauma patients.Conclusion CAR is higher in patients with severe multiple trauma.Furthermore,CAR serves as a risk factor for independently predicting the 28-day mortality of multiple trauma patients.The shock index was significantly higher when CAR was≥4 in multiple trauma patients.
文摘Background: Acute coronary syndrome (ACS) is the leading cardiovascular (CV) cause of mortality. C reactive protein (CRP) has linked with long-term risk of recurrent cardiovascular events or death. Albumin, in contrast to CRP known as a negative acute-phase protein. Thus a newly introduced marker assessed relation of CRP to albumin ratio (CAR), which may provide better results than the use of either marker alone. The aim of the study is to assess the association of C-reactive protein to albumin ratio (CAR) with in-hospital short-term major adverse cardiac events (MACEs) in acute coronary syndrome (ACS) patients. Patients & Methods: A multi-centers prospective cohort study was conducted at coronary intensive care units (CICU) in Baghdad during the period from March to October 2021 that included a total of 132 patients who were diagnosed as a case of ACS. They were assessed for major adverse cardiac events (MACEs) like cardiogenic shock, arrhythmias, post-MI angina, and acute heart failure while inside the ward, in addition to need for early interventional therapeutic approach in relation to (CAR) immediately at time of admission to hospital. Results: High values of CAR, whether using hs-CRP or CRP, were identified as an independent predictor for in-hospital MACEs (P value Conclusion: The CAR was independently correlated with in-hospital short-term MACEs and can be used for risk stratification in patients with ACS.

文摘This study aimed to characterize the physical-chemical and biological properties of pectin(PC)/chia seed mucilage(CM)membranes.PC/CM[100/0(control),80/20%,60/40%,and 40/60%w/w]membranes were prepared using the casting method.The membranes(PC/CM)were thin,yellow,lightly opaque(≈10%)and capable of blocking light UVB(between 66 at 52%).SEM analysis showed the presence of aggregates in the shape of a sphere(≈13μm)and ovoid(≈25μm).The proportion of 80/20 showed an increase in tensile strength(29%)and elastic modulus(19%)when compared to the control.FTIR analysis exhibited intermolecular interactions between PCPC,PC-CM,and CM-CM in the membranes.The thermal analysis(600°C)showed a slight improvement in the percentage of residual mass-loss of 3.31%(80/20)that control.The 40/60 membrane showed the lowest percentage of hemolysis(2.94%)but limited human albumin adsorption capacity.These results suggested that the blend PC/CM may be considered as a biomaterial for medical applications.

文摘Human serum albumin(HSA)is the most abundant protein in plasma and plays an essential physiological role in the human body.Ethanol precipitation is the most widely used way to obtain HSA,and pH and ethanol are crucial factors affecting the process.In this study,infrared(IR)spectroscopy and near-infrared(NIR)spectroscopy in combination with chemometrics were used to investigate the changes in the secondary structure and hydration of HSA at acidic pH(5.6-3.2)and isoelectric pH when ethanol concentration was varied from 0%to 40%as a perturbation.IR spectroscopy combined with the two-dimensional correlation spectroscopy(2DCOS)analysis for acid pH system proved that the secondary structure of HSA changed significantly when pH was around 4.5.What's more,the IR spectroscopy and 2DCOS analysis showed different secondary structure forms under different ethanol concentrations at the isoelectric pH.For the hydration effect analysis,NIR spectroscopy combined with the McCabe-Fisher method and aquaphotomics showed that the free hydrogen-bonded water fluctuates dynamically,with ethanol at 0-20%enhancing the hydrogen-bonded water clusters,while weak hydrogen-bonded water clusters were formed when the ethanol concentration increased continuously from 20%to 30%.These measurements provide new insights into the structural changes and changes in the hydration behavior of HSA,revealing the dynamic process of protein purification,and providing a theoretical basis for the selection of HSA alcoholic precipitation process parameters,as well as for further studies of complex biological systems.
文摘Objective:To investigate the application of heparin-binding protein along with albumin(HBP+ALB)in evaluating the severity of community-acquired pneumonia(CAP)and compares it with single HBP,white blood cells(WBCs),C-reactive protein(CRP),and procalcitonin(PCT).Methods:A total of 226 patients with CAP admitted to the Emergency Department of Zhujiang Hospital,Southern Medical University,Guangdong,China,between March 1,2021,and March 1,2022,were enrolled.The patients were grouped into two groups:mild CAP(n=175)and severe CAP(sCAP)(n=51).Patients'characteristics and laboratory data were obtained.ROC curve and the value of the area under the curve(AUC)were used to evaluate the predictive values of HBP,ALB,WBC,CRP,and PCT.Results:WBC count,CRP,PCT,HBP,creatinine,and D-dimer were higher in the sCAP group,while ALB was lower in the sCAP group(P<0.05)than those in the mild CAP group.The AUCs of WBC,CRP,PCT,HBP,and HBP+ALB were 0.633(95%CI:0.545-0.722,P<0.05),0.635(95%CI:0.542-0.729,P<0.05),0.705(95%CI:0.619-0.791,P<0.05),0.809(95%CI:0.736-0.883,P<0.05),and 0.889(95%CI:0.842-0.936,P<0.05),respectively.Conclusions:HBP+ALB has a higher predictive value than single HBP,PCT,CRP and WBC used alone for the early assessment of CAP.
文摘BACKGROUND Pancreatoduodenectomy represents a complex procedure involving extensive organ resection and multiple alimentary reconstructions.It is still associated with high morbidity,even in high-volume centres.Prediction tools including preoperative patient-related factors to preoperatively identify patients at high risk for postoperative complications could enable tailored perioperative management and improve patient outcomes.AIM To evaluate the clinical significance of preoperative albumin-bilirubin score and other risk factors in relation to short-term postoperative outcomes in patients after open pancreatoduodenectomy.METHODS This retrospective study included all patients who underwent open pancreatic head resection(pylorus-preserving pancreatoduodenectomy or Whipple resection)for various pathologies during a five-year period(2017-2021)in a tertiary care setting at University Medical Centre Ljubljana,Slovenia and Cattinara Hospital,Trieste,Italy.Short-term postoperative outcomes,namely,postoperative complications,postoperative pancreatic fistula,reoperation,and mortality,were evaluated in association with albumin-bilirubin score and other risk factors.Multiple logistic regression models were built to identify risk factors associated with these short-term postoperative outcomes.RESULTS Data from 347 patients were collected.Postoperative complications,major postoperative complications,postoperative pancreatic fistula,reoperation,and mortality were observed in 52.7%,22.2%,23.9%,21.3%,and 5.2%of patients,respectively.There was no statistically significant association between the albumin-bilirubin score and any of these short-term postoperative complications based on univariate analysis.When controlling for other predictor variables in a logistic regression model,soft pancreatic texture was statistically significantly associated with postoperative complications[odds ratio(OR):2.09;95%confidence interval(95%CI):1.19-3.67];male gender(OR:2.12;95%CI:1.15-3.93),soft pancreatic texture(OR:3.06;95%CI:1.56-5.97),and blood loss(OR:1.07;95%CI:1.00-1.14)were statistically significantly associated with major postoperative complications;soft pancreatic texture was statistically significantly associated with the development of postoperative pancreatic fistula(OR:5.11;95%CI:2.38-10.95);male gender(OR:1.97;95%CI:1.01-3.83),soft pancreatic texture(OR:2.95;95%CI:1.42-6.11),blood loss(OR:1.08;95%CI:1.01-1.16),and resection due to duodenal carcinoma(OR:6.58;95%CI:1.20-36.15)were statistically significantly associated with reoperation.CONCLUSION The albumin-bilirubin score failed to predict short-term postoperative outcomes in patients undergoing pancreatoduodenectomy.However,other risk factors seem to influence postoperative outcomes,including male sex,soft pancreatic texture,blood loss,and resection due to duodenal carcinoma.

文摘Objective:Serum albumin(ALB)can transport nutrients to circulating and local immune cells by passing through blood vessels and has attracted attention as a prognostic predictor of non-small cell lung cancer(NSCLC)because it reflects the host immunity from peripheral blood(PBL)to the tumor microenvironment. Methods:Clinical data regarding the PBL and tumor tissues were obtained at The First Hospital of Jilin University between February 2009 and March 2017.We detected indices of glucose and lipid metabolism,classified and counted PBL lymphocytes using flow cy-tometry,determined the tumor-infiltrating lymphocytes by quantitative immunofluorescence,and analyzed the T-cell receptor(TCR)rep-ertoire by high-throughput sequencing of the TCR β-chain.The correlations between ALB and metabolic immune indices were analyzed by t tests and Pearson chi-square test. Results:A total of 211 enrolled NSCLC patients were divided into a relatively high-ALB group(>41.75 g/L,n = 56)and a low-ALB group(≤41.75 g/L,n = 155);patients with high ALB had lower Treg cells(P<0.05)and more CD8+ cytotoxic T cells in the PBL(P<0.01)and a higher proportion of stromal CD8+ tumor-infiltrating lymphocytes(P = 0.047)than patients with low ALB.High ALB was also significantly related to more diversity in the TCR repertoire(P = 0.0021,r2 = 0.5481).Moreover,ALB was identified as an in-dependent prognostic factor based on a multivariate Cox regression analysis(P = 0.032;hazard ratio(HR)= 1.804;95%confidence interval(CI)= 1.035-3.146).The median overall survival in patients with low ALB vs high ALB was 28.2 vs 42.2 months(P=0.0142),respectively.Among patients with nonmetastatic NSCLC(stage Ⅰ-Ⅲ),there was a higher incidence of distant metastasis in the low-ALB group than that in the high-ALB group(41.3%and 22.2%,P=0.043).A low ALB also had a strong association with a higher risk for disease progression(P<0.001)and death(P<0.01;HR = 0.555;95%CI= 0.312-0.988). Conclusions:Albumin could affect the host immunity,and high ALB predicted a reduced risk of distant metastasis and improved the prognosis in NSCLC patients.
