BACKGROUND Thyroid malignancies,while accounting for a small proportion of cancer diagnoses globally,have demonstrated a consistent upward trend in occurrence across diverse populations,with gender-specific analyses revealing a disproportionate burden among women.Despite the characteristically indolent nature of most thyroid carcinomas and their associated high survival rates,emerging evidence points to significant unmet needs regarding psychosocial adaptation and neuropsychiatric sequelae in this growing survivor population.The spectrum of mental health conditions,ranging from affective and anxiety disorders to cognitive impairments,presents substantial barriers to functional recovery and may potentially influence disease trajectories through complex psychoneuroimmunological pathways.Clinical observations consistently report elevated rates of mood disturbances and executive function deficits persisting throughout the cancer continuum,from active treatment into extended follow-up periods.These findings highlight a critical knowledge gap in understanding the dynamic interplay between thyroid cancer biology,its therapeutic interventions,and the development of treatment-resistant psychiatric manifestations that complicate long-term patient care.AIM To analyse the factors influencing the poor prognosis of patients surviving longterm differentiated thyroid cancer with psychiatric disorders and to construct a prediction model.METHODS Forty-eight patients with mental disorders combined with differentiated thyroid cancer who were treated in our hospital during the period of March 2018 to March 2023 were retrospectively selected as the study subjects(thyroid cancer group),and 30 cases each of patients with mental disorders combined with benign thyroid nodules(benign nodules group)and patients with mental disorders alone(mental disorders group),who were treated during the same time period,were selected as controls.The patients with differentiated thyroid cancer were further divided into a poor prognosis group(10 cases)and a good prognosis group(38 cases).The study outcome was poor prognosis as shown by whole body bone imaging within 2 years after thyroid cancer surgery.Factors influencing poor prognosis in survivors of differentiated thyroid cancer were analyzed by univariate and multivariate logistic regression analyses,receiver operating characteristic(ROC)curve analysis was used to assess the predictive efficacy of these factors for poor prognosis,and the DeLong test was used to determine whether there was a statistically significant difference in the area under the curve(AUC)of the model.RESULTS One-way logistic regression analysis showed that tumour diameter[odds ratio(OR)=19.190,P=0.002],T-stage(OR=7.692,P=0.018),extra-glandular infiltration(OR=37.000,P=0.003),degree of differentiation(OR=24.667,P=0.008),serum free T3(OR=22.348,P=0.025),serum free T4(FT4)(OR=1.158,P=0.002),total bilirubin(TBil)(OR=1.792,P=0.004),albumin(OR=0.675,P=0.003),cortisol(OR=1.180,P=0.003),norepinephrine(OR=1.047,P=0.002),angiotensin II(OR=1.975,P=0.002),and superoxide dismutase(OR=0.515,P=0.005)all increased the risk of poor prognosis in patients with psychiatric disorders and long-term differentiated thyroid cancer.Multifactorial logistic regression analysis showed that tumour diameter(OR=16.570,P=0.021),extraglandular infiltration(OR=53.145,P=0.010),FT4(OR=1.186,P=0.007),and TBil(OR=2.823,P=0.048)were independent risk factors for poor prognosis of patients with psychiatric disorders with long-term differentiated thyroid cancer,and the regression equation was:Y=2.808×tumour diameter+3.973×extra-glandular infiltration+0.171×FT4+1.038×TBil-88.138.ROC analysis showed that the predictive power of the overall model(AUC=0.992,P=0.000)was significantly higher than that of independent risk factors(DeLong test P<0.05).CONCLUSION Tumour diameter,extra-glandular infiltration,FT4,and TBil are independent risk factors for poor prognosis in patients with psychiatric disorders with long-term differentiated thyroid cancer,and the combination of these factors is of higher value in predicting the prognosis of patients.These risk factors can be used as a basis to develop a reasonable prognostic management plan in clinical practice for patients with long-term differentiated thyroid cancer with mental disorders,so as to improve the prognosis and quality of life of patients. 展开更多

BACKGROUND The prognosis of patients with poorly differentiated gastric neuroendocrine neoplasms(PDGNENs)is dismal and related research is limited.AIM To investigate the prognostic factors,and validate a novel prognostic nomogram for PDGNEN patients.METHODS We conducted a retrospective study using clinical and pathological data from PDGNEN patients treated at the First Medical Center of the Chinese PLA General Hospital from January 2000 to June 2023.Overall survival(OS)differences were assessed with the Log-rank test and Kaplan-Meier survival curves.Cox regression analysis identified independent risk factors for prognosis.Model performance was evaluated using Harrell’s concordance index,receiver operating characteristic analysis,area under the curve,calibration curves,and decision curve analysis(UDC),including the area under the UDC.RESULTS The study included 336 patients(227 with neuroendocrine carcinoma and 109 with mixed adenoneuroendocrine carcinoma).The average age was 62.7 years.The cohort comprised 80(24.7%)patients in stage I,146(42.9%)in stage II,62(18.1%)in stage III,and 48(14.3%)in stage IV.Significant differences in OS were observed across tumor-node-metastasis stages(P<0.001).Multivariate analysis showed age,Ki-67 index,invasion depth,lymph node metastasis,distant metastasis,and platelet-to-lymphocyte ratio as independent risk factors.We developed a nomogram with a concordance index of 0.779(95%confidence interval:0.743-0.858).Receiver operating characteristic analysis showed area under the curves for 1-year,3-year,and 5-year OS predictions of 0.865,0.850,and 0.890,respectively.The calibration curve demonstrated good agreement with actual outcomes.The area under the UDC for the nomogram vs the 8th American Joint Committee on Cancer tumor-node-metastasis staging system were 0.047 vs 0.027,0.291 vs 0.179,and 0.376 vs 0.216 for 1-year,3-year,and 5-year OS,respectively.CONCLUSION PDGNENs are predominantly found in older men,often in advanced stages at diagnosis,resulting in poor prognosis.The established nomogram demonstrates strong predictive capability and clinical utility. 展开更多

AIM:To assess the visual electrophysiological outcomes in children with functional amblyopia who exhibited poor response to conventional treatment.METHODS:Twenty-one children with functional amblyopia,aged 5.7±2.1y(range:4-10y),underwent comprehensive ophthalmic and refractive evaluations.Spectral domain-optical coherence tomography(SD-OCT)and multifocal electroretinography(mfERG)were conducted to analyze the macular retinal thickness and the first-order response P1 ring of the mfERG in the amblyopic eye(AE)compared to the fellow good eye(GE).RESULTS:Initially,visual acuity in the AE ranged from 20/800 to 20/40,while the GE exhibited a range of 20/25 to 20/20(P<0.01).After 6mo of treatment,17 patients demonstrated improved visual acuity in the AE to 20/50 or better,while 4 children showed no improvement.SD-OCT revealed comparable macular and optic disc structures between the AE and GE.Prior to treatment,the mfERG P1 ring amplitude was significantly reduced in the AE compared to GE(P<0.05).The AE/GE ratio of P1 ring amplitude showed significant improvement post-treatment.However,a smaller AE/GE ratio before treatment was associated with poorer improvement post-treatment.CONCLUSION:In the management of functional amblyopia,a thorough assessment of amblyopic eye examinations is crucial.Approximately 20%of amblyopic eyes may not achieve significant improvement in visual acuity,despite the absence of detectable organic retinal abnormalities.mfERG may reveal underlying abnormalities.Integrating mfERG into initial assessments or treatment follow-ups can aid in identifying potential hidden retinal defects and predicting the prognosis of the amblyopic eye. 展开更多

Ending extreme poverty and achieving sustainable development by 2030 poses a significant challenge for de veloping countries.In the past decade,China has pioneered the Targeted Poverty Alleviation(TPA)strategy and implemented a range of anti-poverty programs,aiming to reconcile poverty reduction with environmental restoration.However,the effectiveness of the TPA strategy in facilitating sustainable development in the poor areas of China(PAC)remains unclear.Drawing on a perspective of systems,this study compiles a panel dataset of 832 nationally designated poverty-stricken counties in China from 2013 to 2020 and employ the coupling coordination degree model to examine the coupling and coordination relationships among economic,social,and environmental systems in the PAC.We find that during the TPA period,the socioeconomic level developed rapidly,while the environmental quality was slightly improved in the PAC.The TPA strategy promotes the co ordinated development of social,economic,and ecological systems in the PAC,shifting the relationship between human and environment from imbalance to coordination.Our findings underscore the necessity for the Chinese government to persist in its environmental restoration efforts in the PAC to guarantee a sustained development progress. 展开更多

BACKGROUND Poorly differentiated thyroid carcinoma(PDTC)is a rare and aggressive form of thyroid cancer.Distant metastasis occurs frequently in PDTC.AIM To determine factors associated with distant metastasis and the effects of metastasis,either diagnosed on initial presentation or developing during follow-up,on mortality in PDTC patients.METHODS Patients with PDTC diagnosed between January 1,1985 and July 31,2022 were identified using a thyroid cancer database at a medical center in Taiwan.Factors associated with distant metastasis and cancer-specific survival(CSS)were analyzed using binary logistic analysis and Cox regression,respectively.Survival analysis was conducted using the Kaplan–Meier method.RESULTS The study cohort included 39 patients with PDTC,including 16 with distant metastasis on initial presentation,5 with metastasis during the follow-up period,and 18 with no evidence of metastasis.Older age(≥45 years)was significantly associated with a higher risk of distant metastasis(odds ratio:5.31;95%confi-dence interval:1.27–22.2;P=0.018),while sex,tumor size,T stage,and N stage were not associated with distant metastasis.Patients with metastatic PDTC,either diagnosed at presentation or developing during follow-up,had poorer 5-year CSS rates(55.0%and 40.0%,respectively)than those without metastasis(5-year CSS,93.8%)(P=0.001 for both comparisons).CONCLUSION Older patients with PDTC have an increased risk of distant metastasis.Patients with metastatic PDTC,both diagnosed at presentation and developing during follow-up,have a dismal prognosis. 展开更多

Objective:To investigate the evaluation value of cardiac color Doppler echocardiography(CDE)in assessing poor prognosis in patients with coronary atherosclerotic heart disease(CAD).Methods:A retrospective review was conducted of 106 patients with coronary artery disease(CAD)who were treated in the hospital’s cardiovascular department between January 2023 and June 2024.All participants received baseline comprehensive Doppler echocardiography(CDE)assessments.Based on whether they experienced a Major Adverse Cardiovascular Event(MACE)within one year of follow-up,the patients were categorized into either a MACE group or a non-MACE group.The study compared baseline clinical information and CDE parameters,specifically left ventricular ejection fraction(LVEF),wall motion score index(WMSI),and mitral annular E/e’ratio,between the two groups.Independent predictors of MACE were identified using multivariate logistic regression analysis.Results:A total of 29 out of the 106 patients experienced MACE during the oneyear follow-up.Compared with the non-MACE group,the MACE group had a higher prevalence of diabetes mellitus.In terms of CDE parameters,the MACE group had a lower LVEF than the non-MACE group(p<0.05),while WMSI,average E/e’,pulmonary artery systolic pressure(PASP),and mitral regurgitation(MR)proportion were all higher in the MACE group than in the non-MACE group(p<0.05).Multifactor logistic regression analysis revealed that after adjusting for confounding factors such as diabetes,WMSI(OR=3.003,95%CI:1.226–7.356,p=0.016)and mean E/e’(OR=1.281,95%CI:1.006–1.539,p=0.008)were independent predictors of the occurrence of major adverse cardiovascular events(MACE).Conclusion:WMSI and E/e’diagnosed by color Doppler echocardiography(CDE)hold significant and independent assessment value for predicting poor prognosis in patients with coronary artery disease(CAD). 展开更多
