文摘Stichopus chloronotus is a tropical sea cucumber with facultative asexual reproduction in the Indo-Western Pacific,yet its wild populations are decreasing due to extensive harvesting.Understanding the species’genetic characteristics is essential for effective management and conservation.To develop novel microsatellite markers and assess the genetic diversity,clonality,and genetic structure of eight populations of S.chloronotus in the South China Sea,193 individuals from eight populations across Wuzhizhou and Fenjiezhou(Boundary)islands were analyzed using nine newly developed microsatellite markers and five previously established markers.RNA-Seq was employed to obtained 62662 unigenes and identified 16926 microsatellite loci.Fourteen polymorphic microsatellite loci were developed,of which 11 were highly polymorphic(polymorphic information content>0.5).The number of alleles(N_(a))ranged from 3 to 6 per locus,and the average Shannon diversity index(I)was 1.107.All the populations exhibited asexual reproduction,with regional variations in reproductive modes.Asexual reproduction was predominant in the northwestern Wuzhizhou Island population(SY 7)and the Fenjiezhou Island population(LS 8),where four and five predominant clones represented more than 89%of the individuals,which led to reduced genetic diversity.Overall,genetic diversity was moderately low,with significant genetic differentiation among populations(F_(ST)=0.33;P<0.001),suggesting limited gene flow(the number of migrants(N_(m))<1).These findings highlight the role of reproductive strategies in shaping fine-scale genetic differentiation in S.chloronotus.The limited recruitment success of sexually produced larvae and habitat heterogeneity likely constrain clone dispersal,contributing to distinct genetic restructuring.This study provided key insights into the interplay between reproductive strategies and genetic patterns in sea cucumbers,offering a scientific basis for targeted conservation efforts.

文摘BACKGROUND The deleterious effects of surgical trauma and subsequent postoperative complications pose significant challenges to the smooth recovery of patients after gastric cancer(GC)resection despite the substantial curative benefits provided by surgical interventions for GC.Hence,the investigation of more optimal and efficacious treatment approaches has become an urgent necessity in the medical community.AIM To investigate the association of Sijunzi decoction plus chemotherapy with the gastrointestinal function and serum markers of patients after GC surgery.METHODS This study included patients who underwent GC surgery from June 2022 to February 2024.The control group included 45 patients who received chemotherapy(oxaliplatin+calcium folinate+5-fluorouracil),whereas the research group consisted of 54 patients who received Sijunzi decoction therapy in addition to the treatment administered in the control group.Comparative analyses were conducted from the following perspectives:Gastrointestinal function(defecation time,intestinal gas discharge time,and hospitalization time),serum markers[carcinoembryonic antigen(CEA),carbohydrate antigen(CA)125,and CA199],nutritional indicators total protein(TP)and transferrin(TRF),traditional Chinese medicine(TCM)syndrome score,and grades Ⅲ–Ⅳ adverse events(gastrointestinal reactions,renal/liver function impairment,and myelosuppression).RESULTS The two groups demonstrated similar defecation time(P>0.05),but the intestinal gas discharge time and hospitalization time were significantly shortened in the research group(P<0.05).Further,the research group exhibited significant CEA,CA125,and CA199 reductions after treatment,which were lower compared to the control group,as well as notable increases in TP and TRF that were statistically higher than the control group(all P<0.05).Furthermore,the research group demonstrated an evident decrease in TCM syndrome scores in areas,such as poor appetite,epigastric distension and pain,fatigue and weakness(P<0.01),and abdominal distension after eating,which are notably lower than those in the control group(P<0.01),with a comparable incidence of grades Ⅲ-Ⅳ adverse events(P>0.05).CONCLUSION Our research results indicate that Sijunzi decoction plus chemotherapy exerts a good rehabilitation-promoting effect on gastrointestinal function in patients after GC surgery and significantly downregulates abnormally increased CEA,CA125,and CA199 levels.
文摘BACKGROUND An increasing number of studies to date have found preoperative magnetic resonance imaging(MRI)features valuable in predicting the prognosis of rectal cancer(RC).However,research is still lacking on the correlation between preoperative MRI features and the risk of recurrence after radical resection of RC,urgently necessitating further in-depth exploration.AIM To investigate the correlation between preoperative MRI parameters and the risk of recurrence after radical resection of RC to provide an effective tool for predicting postoperative recurrence.METHODS The data of 90 patients who were diagnosed with RC by surgical pathology and underwent radical surgical resection at the Second Affiliated Hospital of Bengbu Medical University between May 2020 and December 2023 were collected through retrospective analysis.General demographic data,MRI data,and tumor markers levels were collected.According to the reviewed data of patients six months after surgery,the clinicians comprehensively assessed the recurrence risk and divided the patients into high recurrence risk(37 cases)and low recurrence risk(53 cases)groups.Independent sample t-test andχ2 test were used to analyze differences between the two groups.A logistic regression model was used to explore the risk factors of the high recurrence risk group,and a clinical prediction model was constructed.The clinical prediction model is presented in the form of a nomogram.The receiver operating characteristic curve,Hosmer-Lemeshow goodness of fit test,calibration curve,and decision curve analysis were used to evaluate the efficacy of the clinical prediction model.RESULTS The detection of positive extramural vascular invasion through preoperative MRI[odds ratio(OR)=4.29,P=0.045],along with elevated carcinoembryonic antigen(OR=1.08,P=0.041),carbohydrate antigen 125(OR=1.19,P=0.034),and carbohydrate antigen 199(OR=1.27,P<0.001)levels,are independent risk factors for increased postoperative recurrence risk in patients with RC.Furthermore,there was a correlation between magnetic resonance based T staging,magnetic resonance based N staging,and circumferential resection margin results determined by MRI and the postoperative recurrence risk.Additionally,when extramural vascular invasion was integrated with tumor markers,the resulting clinical prediction model more effectively identified patients at high risk for postoperative recurrence,thereby providing robust support for clinical decision-making.CONCLUSION The results of this study indicate that preoperative MRI detection is of great importance for predicting the risk of postoperative recurrence in patients with RC.Monitoring these markers helps clinicians identify patients at high risk,allowing for more aggressive treatment and monitoring strategies to improve patient outcomes.
文摘Parkinson’s disease(PD)is a common neurodegenerative disorder with increasing incidence and disability rates globally,placing a heavy burden on patients and their families.In the prodromal phase of PD,nonmotor symptoms,particularly depression and sleep disorders,are frequent,with profound effects on disease progression and patient quality of life.Emerging research highlights the critical role of inflammatory markers-including interleukins and tumor necrosis factor-in the pathogenesis of prodromal PD.These inflammatory mediators participate in neurodegenerative processes and may induce or exacerbate depressive symptoms and sleep disorders by disrupting the function of the hypothala-micpituitary-adrenal axis and affecting neurotransmitter,including serotonin,metabolism.Understanding their correlations with nonmotor symptoms in prodromal PD remains incomplete,limiting our ability to develop targeted interventions.This comprehensive review aims to investigate the specific correlations between inflammatory markers and nonmotor symptoms-particularly depression and sleep disorders-in prodromal PD.The findings could have important practical applications,potentially leading to the development of new diagnostic tools and therapeutic strategies for managing PD.By identifying and understanding these correlations,healthcare providers may better predict disease progression and implement more effective treatments for nonmotor symptoms in PD.
文摘BACKGROUND Rectal cancer requires accurate preoperative assessment of T stage and differentiation grade for treatment planning.Traditional imaging and serum markers have limitations in diagnostic accuracy.AIM To evaluate the predictive value of dynamic contrast-enhanced-magnetic resonance imaging(DCE-MRI)parameters and serum biomarkers[carbohydrate antigen(CA)19-9,CA125]for determining T stage and differentiation grade in rectal cancer.METHODS We conducted a retrospective review of clinical data from 126 patients who were pathologically diagnosed with rectal cancer between January 2021 to June 2024.Each patient underwent DCE-MRI scans and serum tests for CA19-9 and CA125.Receiver operating characteristic curves were utilized to assess the diagnostic value of DCE-MRI parameters,including volume transfer constant(Ktrans),rate constant(Kep),and volume fraction of extravascular extracellular space(Ve),as well as serum biomarkers for staging and grading rectal cancer.The DeLong test algorithm was employed to evaluate differences in diagnostic performance among the various indicators.RESULTS There were statistically higher levels of Ktrans,Ve,CA19-9,and CA125 serum concentrations of patients with advanced T stages and on poorly differentiated tumors than that in patients with low stages and moderate to high differentiation(P<0.05).Combined use of Ktrans and Ve for T stage diagnosis showed an area under the curve(AUC)of 0.892[95%confidence interval(CI):0.832-0.952],which increased to 0.923(95%CI:0.865-0.981)when combined with serum biomarkers.For grades differentiation,the combined DCE-MRI parameters had an AUC of 0.883(95%CI:0.821-0.945),which rose to 0.912(95%CI:0.855-0.969)when combined with serum markers.According to the Delong test,the combined diagnostic method performed better than a single diagnostic method(P<0.05).CONCLUSION The combined application of DCE-MRI functional parameters and serum tumor markers can significantly improve the diagnostic accuracy of T staging and differentiation degree of rectal cancer,providing a new approach to improve the preoperative assessment system of rectal cancer.This combined diagnostic model has important clinical application value,but further validation is needed through large-scale multicenter studies.

文摘Chinese chestnut is an important economic forest tree species with enormous application value in the wood,medical,and chemical industries.Currently,the limited genome-wide SSR molecular marker information on chestnut resources significantly restricts research on the genetic diversity and identification of chestnut resources.To address this issue,we used GMATA to screen simple sequence repeat(SSR)markers throughout the Chinese chestnut genome.A total of 312,302 molecular markers were obtained with a density of 434.38 Mb-1.Subsequently,all SSR markers were examined for polymorphism using the Hip STR program and 138,208 polymorphic loci were ultimately obtained.To verify the capability of the developed SSR for identification,we randomly selected 36 markers on 12 chromosomes to construct fingerprint maps of 96 ancient Chinese chestnut resources from the Yanshan Mountains.The results showed that only six pairs of primers were required to create a unique DNA fingerprint of the tested ancient trees,showing that the developed markers have good potential for identification.We then evaluated the inter-specific universality and polymorphism of these markers using 91 Castanea plants of three different species.The molecular markers amplified 94%of the interspecies with a polymorphic information content(PIC)value of 0.859.Cluster analysis revealed that the resources can be well differentiated using these developed markers,and these markers can be widely used to identify interspecific boundaries.The results of this study proved that the developed molecular markers have the potential for assessing genotypic diversity,which can provide references for genetic diversity research,variety identification,kinship analysis,the selection of good products,and the construction of core germplasm resources of chestnut and even chestnut plants.Also these markers provide a solid foundation for the molecular design of hybrids,improved breeding and development of germplasm resources.

文摘BACKGROUND Colorectal cancer(CRC)is a prevalent malignant neoplasm characterized by subtle early manifestations.AIM To investigate the correlation among serum lipid profiles,the triglyceride-glucose(TyG)index,and the atherosclerotic index(AI)in patients with CRC.Furthermore,it explored the clinical diagnostic utility of combining serum lipids with cancer antigens in the context of CRC.METHODS A retrospective analysis encompassed 277 patients with CRC and 1034 healthy individuals.RESULTS Following propensity score matching,patients with CRC exhibited significantly reduced levels of serum triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol,and low-density lipoprotein cholesterol(LDL-C),as well as a diminished TyG index.Conversely,they displayed elevated AI levels compared to their healthy counterparts.Patients in advanced stages exhibited lower serum levels of TG,TC,and LDL-C compared to those in early stages.Patients with positive lymph node metastasis demonstrated reduced levels of TG,LDL-C,and the TyG index.Receiver operating characteristic analysis revealed that the combination of the TyG index,carcinoembryonic antigen,and carbohydrate antigen 19-9 yielded the highest positive prediction rate for CRC at 75.3%.CONCLUSION Preoperative serum lipid profiles exhibit a robust association with patients with CRC.The concurrent assessment of multiple serum lipids and cancer antigens effectively enhances the diagnostic accuracy for CRC.
文摘BACKGROUND Non-ST segment elevation myocardial infarction(NSTEMI)poses significant challenges in clinical management due to its diverse outcomes.Understanding the prognostic role of hematological parameters and derived ratios in NSTEMI patients could aid in risk stratification and improve patient care.AIM To evaluate the predictive value of hemogram-derived ratios for major adverse cardiovascular events(MACE)in NSTEMI patients,potentially improving clinical outcomes.METHODS A prospective,observational cohort study was conducted in 2021 at the Internal Medicine Clinic of the University Hospital in Tuzla,Bosnia and Herzegovina.The study included 170 patients with NSTEMI,who were divided into a group with MACE and a control group without MACE.Furthermore,the MACE group was subdivided into lethal and non-lethal groups for prognostic analysis.Alongside hematological parameters,an additional 13 hematological-derived ratios(HDRs)were monitored,and their prognostic role was investigated.RESULTS Hematological parameters did not significantly differ between non-ST segment elevation myocardial infarction(NSTEMI)patients with MACE and a control group at T1 and T2.However,significant disparities emerged in HDRs among NSTEMI patients with lethal and non-lethal outcomes post-MACE.Notably,neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)were elevated in lethal outcomes.Furthermore,C-reactive protein-to-lymphocyte ratio(CRP/Ly)at T1(>4.737)demonstrated predictive value[odds ratio(OR):3.690,P=0.024].Both NLR at T1(>4.076)and T2(>4.667)emerged as significant predictors,with NLR at T2 exhibiting the highest diagnostic performance,as indicated by an area under the curve of 0.811(95%CI:0.727-0.859)and OR of 4.915(95%CI:1.917-12.602,P=0.001),emphasizing its important role as a prognostic marker.CONCLUSION This study highlights the significant prognostic value of hemogram-derived indexes in predicting MACE among NSTEMI patients.During follow-up,NLR,PLR,and CRP/Ly offer important insights into the inflammatory processes underlying cardiovascular events.
文摘BACKGROUND Perioperative blood transfusion is common in gastric cancer surgery,yet its im-pact on postoperative inflammation,stress response,and long-term prognosis remains incompletely understood.AIM To investigate the effect of perioperative blood transfusion on postoperative infla-mmation and stress markers,as well as its correlation with prognosis in patients with gastric cancer undergoing radical gastrectomy.METHODS A retrospective analysis was conducted on 200 patients who underwent gastric cancer surgery,divided into a non-transfusion group(n=108)and a transfusion group(n=92).Baseline characteristics,pathological features,postoperative inflammatory and stress markers,complications,and long-term survival were compared between the two groups.Statistical analyses were performed using t-tests,χ2 tests,and multivariate Cox regression analysis.RESULTS The transfusion group had a lower T-stage distribution and higher intraoperative blood loss than the non-transfusion group(P<0.05).Postoperative inflammatory markers such as white blood cell count,neutrophil/lymphocyte ratio,C-reactive protein,interleukin-6,and stress markers like cortisol and adrenaline were sig-nificantly higher in the transfusion group than in the non-transfusion group(P<0.05).The incidence of postoperative complications was also higher in the transfusion group than in the non-transfusion group.Overall survival(OS)and disease-free survival(DFS)were significantly shorter in the transfusion group(P<0.05)than in the non-transfusion group.Multivariate Cox regression analysis showed that transfusion had a negative impact on OS and DFS.CONCLUSION Perioperative blood transfusion is associated with increased postoperative inflammation,stress reactions,complication rates,and adverse prognosis in patients with gastric cancer.Reducing unnecessary transfusions can improve postoperative recovery and long-term prognosis.
文摘In this article,we critically appraise the study by Wu et al,which investigated the prognostic value of preoperative inflammatory and nutritional markers in colorectal cancer patients with peritoneal metastasis.This retrospective cohort study included 133 patients.The findings indicate that patients with high neutrophil-to-lymphocyte ratios(NLRs)or lower hemoglobin(Hb)levels have significantly shorter overall survival(OS)than those with lower NLRs or normal Hb levels,respectively.Furthermore,age,carbohydrate antigen 199 levels,the NLR,Hb,and the peritoneal cancer index were identified as independent prognostic factors for OS.A nomogram was subsequently developed,demon-strating its ability to accurately predict the OS of colorectal cancer patients with peritoneal metastasis.This study introduces a potentially valuable prognostic tool for these patients.However,further validation in multicenter cohorts is needed to confirm its clinical applicability,to assess its limitations,and to elucidate the underlying mechanism of these identified biomarkers.

文摘BACKGROUND Gastric cancer is a major global health concern,often diagnosed at advanced stages,leading to poor prognosis.Proximal and distal gastric cancers exhibit distinct clinicopathological features.AIM To investigate the diagnostic value of hematological and inflammatory markers in differentiating proximal and distal gastric cancers and to evaluate their association with clinical outcomes.METHODS A retrospective cohort study was conducted on 150 patients diagnosed with gastric adenocarcinoma through histopathological analysis.Patients were categorized into proximal gastric cancer and distal gastric cancer groups.Laboratory parameters were analyzed.RESULTS Of the 150 patients,84 had proximal gastric cancer and 66 had distal gastric cancer.Dysphagia was significantly more common in the proximal gastric cancer group,while anemia and higher platelet-to-lymphocyte ratio values were observed in the distal gastric cancer group(P=0.031).Tumor stage and neutrophil-to-lymphocyte ratio emerged as independent predictors of all-cause mortality.No significant differences were found in other laboratory or biochemical parameters between the groups.CONCLUSION Proximal and distal gastric cancers demonstrate distinct clinical and laboratory profiles.The platelet-to-lymphocyte ratio may serve as a valuable marker in differentiating cancer localization,while the neutrophil-to-lymphocyte ratio is a prognostic indicator for mortality.These findings highlight the potential of hematological markers in optimizing diagnosis and treatment strategies for gastric cancer.
文摘Malaria continues to pose a significant global health challenge despite a significant achievement in control and elimination in certain areas.Accurate and timely diagnosis is crucial for effective disease management and control,and finally leading to elimination.However,microscopy and rapid diagnostic tests(RDTs)have traditionally been the primary malaria diagnostic tools used globally,with certain shortcomings,including their limited sensitivity,specificity,and inability to identify asymptomatic infections.Serological markers have emerged as promising alternatives in malaria serosurveillance,particularly in countries where targets have already been set for elimination.This review highlights the advantages of serological markers over conventional diagnostic techniques and discusses some of the most promising serological markers against Plasmodium species-specific antigens.The implementation of serosurveillance,coupled with the utilization of these serological markers represents a transformative shift in malaria surveillance.By capitalizing on the immune memory of individuals,serosurveillance also enables the identification of recent and past infections.This approach is particularly valuable in low-transmission settings and for tracking changes in malaria prevalence over time.While recognizing the use of serological markers across various global contexts,this review predominantly emphasizes their significance within the framework of India.
文摘Colorectal cancer(CRC)is the third most common malignancy and the second leading cause of cancer-related mortality worldwide,responsible for approximately 900000 deaths annually.Inflammation and malnutrition significantly influence patients'responses to treatment.Markers such as serum albumin concentration,the prognostic nutritional index,nutritional risk index(NRI),geriatric NRI,and the systemic immune-inflammation index enable the early identification of high-risk patients,facilitating timely interventions that can improve survival and reduce morbidity.A comprehensive understanding and application of these markers allow for better risk stratification in CRC patients,optimizing their management and outcomes.

文摘Background Cotton is a significant crop for fiber production;however,seed shape-related traits have been less investigated in comparison to fiber quality.Comprehending the genetic foundation of traits associated with seed shape is crucial for improving the seed and fiber quality in cotton.Results A total of 238 cotton accessions were evaluated in four different environments over a period of two years.Traits including thousand grain weight(TGW),aspect ratio(AR),seed length,seed width,diameter,and roundness demonstrated high heritability and significant genetic variation,as indicated by phenotypic analysis.The association analysis involved 145 simple sequence repeats(SSR)markers and identified 50 loci significantly associated with six traits related to seed shape.The markers MON_DPL0504aa and BNL2535ba were identified as influencing multiple traits,including aspect ratio and thousand grain weight.Notably,markers such as HAU2588a and MUSS422aa had considerable influence on seed diameter and roundness.The identified markers represented an average phenotypic variance between 3.92%for seed length and 16.54%for TGW.Conclusions The research finds key loci for seed shape-related traits in cotton,providing significant potential for marker-assisted breeding.These findings establish a framework for breeding initiatives focused on enhancing seed quality,hence advancing the cotton production.
文摘The retrospective cohort study by Zuo et al investigates the interplay between microsatellite instability(MSI)status,nutritional indicators,and inflammatory profiles in colorectal cancer(CRC).Analyzing 56 patients,the study reveals that MSI-high tumors are associated with significantly lower serum albumin,body mass index,and absolute lymphocyte counts,alongside elevated neutrophil-tolymphocyte ratios compared to microsatellite stable tumors.These findings highlight distinct immunological and nutritional profiles in MSI-high CRC,suggesting potential clinical utility in risk stratification and personalized treat-ment.While the study underscores the importance of MSI status in CRC mana-gement,its single-center design and limited sample size warrant validation through multicenter trials.This article contextualizes these findings within the broader landscape of CRC research,emphasizing the need for integrating bio-markerdriven strategies into clinical practice to optimize outcomes for patients with differing MSI statuses.

文摘BACKGROUND Although histopathological examination via colonoscopy is the benchmark for ulcerative colitis(UC)diagnosis,its limitations underscore the urgency of identifying noninvasive diagnostic markers.AIM To investigate the clinical relevance of systemic inflammatory markers in assessing disease severity among patients with UC.METHODS In this study,117 consecutive patients with UC hospitalized between January 2024 and January 2025 were analyzed and stratified by disease severity using the modified Mayo score:Mild(n=37),moderate(n=45),and severe(n=35)groups.Demographic and clinical data were recorded,and serum concentrations of inflammatory markers-interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α),and C-reactive protein(CRP)-were measured and compared across the groups.Correlation analyses(Spearman’s rank)were conducted to evaluate the relationships between cytokine levels and disease severity.Disease severity-associated predictors were identified through regression(univariate and multivariate)analyses,supplemented by sensitivity testing to validate consistency.The diagnostic performance of inflammatory markers for disease progression was assessed using the receiver operating characteristic curve.RESULTS Serum IL-6,TNF-α,and CRP levels exhibited a significant stepwise increase with worsening UC severity.Each inflammatory marker demonstrated a strong positive correlation with disease severity.Multivariate analysis identified smoking history,alcohol abuse,IL-6,TNF-α,and CRP as independent predictors of disease progression.In the sensitivity testing,directional effects of these variables were aligned(all odds ratios>1),indicating robust results.Receiver operating characteristic analysis indicated that the combined cytokine panel demonstrated superior diagnostic accuracy(area under the curve 0.917,88.6%sensitivity,80.5%specificity)when compared with individual markers(area under the curves,0.763-0.820).CONCLUSION IL-6,TNF-α,and CRP levels strongly correlate with the progression of UC and may serve as reliable biomarkers for disease activity.The combined measurement of these markers could facilitate the early identification of high-risk patients,enabling prompt delivery of clinical intervention and personalized management.

文摘Peanut kernels rich in oil,particularly those with oleic acid as their primary fatty acid,are in high demand among consumers,the food industry,and farmers due to their superior nutritional content,extended shelf life,and health benefits.The oil content and fatty acid composition are governed by multiple genetic factors.Identifying the quantitative trait loci(QTLs)related to these attributes will facilitate marker-assisted selection and genomic selection,thus enhancing quality-focused peanut breeding programs.For this purpose,we developed a population of 521 recombinant inbred lines(RILs)and tested their kernel quality traits across five different environments.We identified two major and stable QTLs for oil content,qOCAh12.1 and qOCAh16.1.The markers linked to these QTLs were designed by Kompetitive allele-specific PCR(KASP)and subsequently validated.Moreover,we found that the superior haplotype of oil content in the qOCAh16.1 region was conserved within the plant introduction(PI)germplasm cluster,as evidenced by a diverse peanut accession panel.In addition,we determined that qAh09 and qAh19.1,which harbor the key gene encoding fatty acid desaturase 2(FAD2),influence all seven fatty acids,palmitic,stearic,oleic,linoleic,arachidic,gadoleic,and behenic acids.Regarding the protein content and the long-chain saturated fatty acid behenic acid,qAh07 emerged as the major and stable QTL,accounting for over 10%of the phenotypic variation explained(PVE).These findings can enhance marker-assisted selection in peanut breeding,with the aim of improving the oil content,and deepen our understanding of the genetic mechanisms that shape fatty acid composition.

文摘Bariatric surgery significantly improves glycemic control and can lead to type 2 diabetes remission.However,the reliability of glycated hemoglobin(HbA1c)as a type 2 diabetes biomarker post-surgery can be confounded by conditions such as anemia and gastrointestinal complications.Hence,we explored the use of alter-native biomarkers such as glycated albumin(GA),1,5-anhydroglucitol(1,5-AG),and insulin-like growth factor binding protein-1(IGFBP-1)to monitor glycemic control more effectively in post-bariatric surgery patients.Measuring GA and 1,5-AG levels can detect glycemic variability more sensitively than HbA1c,especially under non-fasting conditions.GA shows promise for short-term monitoring post-surgery while 1,5-AG could be useful for real-time glucose monitoring.IGFBP-1 can be used to monitor metabolic improvement and to predict HbA1c normal-ization.However,challenges in assay standardization and cost remain significant barriers to their clinical adoption.Although these biomarkers could offer a more personalized approach to glucose monitoring(thereby addressing the limitations of utilizing HbA1c in this endeavor in post-bariatric surgery patients),this would require overcoming technical,logistical,and cost-related challenges.While using GA,1,5-AG,and IGFBP-1 shows promise for glycemic monitoring,further research and validation are crucial for their routine clinical implementation,espe-cially in the context of diabetes management post-bariatric surgery.
文摘Background:An increasing number of patients with Fontan circulation are reaching adulthood;however,long-term outcomes remain limited by Fontan failure,which is characterized by elevated central venous pressure(CVP)and reduced cardiac output.Red blood cell distribution width(RDW),a readily available hematological parameter,is a known prognostic marker of heart failure.However,its relationship with invasive hemodynamics in adolescent and adult Fontan patients has not been fully examined.Objectives:To clarify the association between RDW and invasive hemodynamic indices in adolescent and adult Fontan patients and assess the utility of RDW as a noninvasive circulatory marker.Methods:This single-center retrospective study included consecutive Fontan patients aged≥16 years who underwent routine cardiac catheterization≥5 years after surgery,between June 2014 and July 2025.Laboratory data and catheter-derived hemodynamics were also analyzed.The primary endpoint was the correlation between RDW and CVP,and the secondary endpoint was the correlation between RDW and central venous oxygen saturation(ScvO_(2)).Results:Forty patients(median age:22 years)were analyzed.The median RDW was 13.3%,and the median CVP was 11.0 mmHg.RDW correlated positively with CVP(ρ=0.57,p<0.001)and negatively with ScvO_(2)(ρ=-0.66,p<0.001)and the cardiac index(ρ=-0.34,p=0.03).Patients with elevated RDW(>14.5%)had higher CVP(14.5 vs.10.5 mmHg,p<0.001)and lower ScvO_(2)(63.8%vs.76.1%,p<0.001),compared with those with normal RDW.Multivariable analysis identified RDW as an independent predictor of ScvO_(2)(p<0.001).Conclusions:In adolescents and adults after the Fontan procedure,RDW was significantly associated with elevated CVP and reduced ScvO_(2)and independently predicted impaired oxygen delivery.RDW is inexpensive,widely accessible,and may serve as a practical noninvasive biomarker for the early detection of Fontan failure and the optimization of invasive testing and interventions during long-term follow-up.
