Background and Aims:As a core data source in the development of medical informatization,the front page of inpatient medical records plays a crucial role in determining the usability of research data and the scientific quality of clinical decision-making.Given the relatively standardized diagnostic and treatment protocols for thyroid malignancies,this disease serves as a representative model for evaluating the data quality of medical record front sheets.This study aimed to systematically assess the accuracy of diagnostic and surgical procedure coding for thyroid malignancies on the medical record front page,identify existing problems,and explore strategies for improvement and the potential for future application in clinical research.Methods:A total of 3 361 patients who underwent initial surgical treatment and were pathologically confirmed with thyroid cancer at the Department of Thyroid Surgery,the First Affiliated Hospital of Kunming Medical University from January 2018 to December 2020 were retrospectively included.Postoperative pathology reports and surgical records were used as reference standards to evaluate the accuracy of primary and secondary diagnosis codes,as well as primary and secondary surgical procedure codes on the medical record front page.Results:The accuracy rate of primary diagnosis coding reached 98.8%.However,among 1 368 patients with cervical lymph node metastasis,only 31.2%had correctly recorded secondary diagnosis codes and metastatic sites,with an omission rate as high as 67.8%.The overall accuracy rate for primary surgical procedure coding was 90.4%,with thyroid lobectomy(TL)and total thyroidectomy(TT)coding accuracies of 85.5%and 96.0%,respectively.Among the coding errors,70.0%involved TL procedures being incorrectly coded as TT.Secondary surgical procedure codes—mainly for lymph node dissection—were highly inconsistent,with up to 14 different coding types,reflecting a lack of standardization and unified input criteria.Notably,the error rate for primary surgical coding in 2020 increased significantly compared with the previous two years,suggesting subjectivity and variability in manual data entry.Conclusion:This study highlights major accuracy deficiencies in surgical procedure coding for thyroid malignancies on the medical record front page,which may compromise the scientific validity of real-world data.Going forward,leveraging artificial intelligence technologies to support structured documentation and automated coding,alongside establishing a proactive quality control system through multidisciplinary collaboration,may significantly improve data accuracy.These efforts are essential for strengthening data foundations for precision treatment,performance evaluation,insurance payment,and clinical research on thyroid cancer.

Objective To explore the feasibility and operability in identifying the therapeutic dominant stages of traditional Chinese medicine(TCM)based on subdivision model of disease course.Methods The hierarchical Bayesian model was used to differentiate the disease course of 125 cases of premature ovarian failure(POF),and the disease course of POF were divided into the occult stage,diminished ovarian reserve(DOR)stage,premature ovarian insufficiency(POI)stage,and POF stage.An then the paired sample t-test,Pearson correlation analysis and expert in-depth interview were used for the analysis of the therapeutic effects of TCM for POF at various stages.Results(1)Compared with POF stage,DOR and POI stages were frequently intervened by Chinese patent medicine.(2)In DOR(complicated with POI)stage and POF stage,there was significant difference between the degree of TCM intervention and the therapeutic effect(t =-3.70,P＜0.001).(3)The degree of TCM intervention was positively correlated with treatment outcomes in the DOR stage(r = 0.679,P＜0.001),so did in the POF stage(r = 0.432,P＜0.001),but the correlation in the POF stage was slightly lower than that in the DOR stage.(4)The results of in-depth interviews with experts of TCM gynecology showed that in the concealed phase of POF,the prognosis would be most favorable if TCM regulation and intervention were performed.In the DOR stage and POI stage,treatment with Chinese medicine prescriptions usually brought about better curative effect and prognosis.For the patients at POF stage,the therapeutic effect of TCM depended on the patients'compliance and the treatment course,and the effect was relatively not as good as that of the previous stages.Conclusion In the DOR stage and POF stage,the higher the degree of TCM intervention,the better the prognosis will be achieved for the patients treated with western medicine.In the POF stage,the efficacy of TCM intervention is reduced to a certain extent compared with the DOR stage.The results indicated that it is feasible and operable to identify the TCM therapeutic dominant stages based on the subdivision model of disease course.

Objective To observe the value of 5.0T MR susceptibility weighted imaging(SWI)for displaying cerebral small veins and detecting cerebral microbleeds(CMB).Methods Head MR examinations were prospectively performed using both 3.0T and 5.0T MR scanner in 30 stroke patients suspected caused by cerebral small vessel disease.The image quality,effect of displaying cerebral small veins and detecting CMB were compared between 3.0T and 5.0T SWI.Results The image quality scores,signal-to-noise ratios,contrast-to-noise ratios,scores of displaying deep cerebral veins and subcortical veins,the counts of detecting CMB and iron deposition on cortical surface of 5.0T SWI were all higher than those of 3.0T SWI(all P＜0.05).High consistency of CMB positions was found between 3.0T and 5.0T SWI(Kappa=1.0).Conclusion The effect of 5.0T MR SWI for displaying cerebral small veins and detecting cerebral microbleeds were better than 3.0T MR SWI,which could be used to assess stroke caused by cerebral small vascular disease.

Objective Based on the scoping review framework,we collected cancer-related cognitive impairment(CRCI)assessment tools from home and abroad to provide references for the standardized use of such assessment tools.Methods Chinese and English databases,such as Pubmed,Embase,Web of Science Core Collection database,CNIK,Wanfang database,and VIP database,were systematically searched from the establishment of the database to April 12,2024,to extract the basic information of evaluation tools,and the search results were standardized.Results 31 articles were included,of which 26 were about the development or validation of assessment tools,and 5 were about the localization and application of assessment tools,involving 19 subjective assessment tools and 8 objective assessment tools.Most of the subjective assessment tool reliability and validity tests were internal consistency reliability tests and concurrent validity tests;14 subjective assessment tools were multidimensional scales;6 objective assessment tools measured retest reliability;4 were unidimensional measures.Conclusion The assessment tools chosen for the current studies vary.It is recommended to choose the evaluation tools and judgment standards recommended by the International Cognitive and Cancer Working Group to carry out relevant research.In the future,the existing CRCI assessment tools should be further verified and improved,and a localized CRCI assessment tool should be continuously introduced or developed.

Objective:To evaluate the clinical value of 5.0 T ultra-high filed MRI system in assessing intracranial arteries segments and vessel branchers.Methods:This study was a prospective study. Totally 40 consecutive healthy volunteers were recruited from Zhongshan Hospital, Fudan University from September 1, 2021 to November 30, and all participants who underwent either 3.0 T or 5.0 T time-of-flight MR angiography (TOF-MRA) in random order were divided into 3.0 T MR group and 5.0 T MR group with 20 volunteers for each group. Image quality was assessed by Likert 5 scoring systems and signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR),and score in visualization of intracranial arteries [middle cerebral artery (MCA) and its segments, anterior cerebral artery (ACA) and its segments, posterior cerebral artery (PCA) and its segments, lenticulostriate arteries (LA) and pontine artery (PA)] were assessed from 0 to 3 (≥2: good depiction of vessel segment). Quantitative indicators were compared between 2 groups using independent t test or Mann-Whitney U test. Results:Among the 40 subjects, there were 29 males and 11 females, aged 20-69 (50±12) years. SNR and CNR were both significantly higher in 5.0 T MR group than those in 3.0 T MR group (SNR: 187±9 vs 91±4, t=31.59, P<0.001; CNR: 156±7 vs 70±4, t=31.45, P<0.001), but there was no significant difference in subjective scores of image quality between the 5.0 T MR and 3.0 T MR groups [5.0 (4.0, 5.0), 5.0 (5.0, 5.0) points, respectively, Z=-1.23, P=0.218]. In the evaluation of cerebral arteries, the visualizations of the proximal and middle segments of MCA, ACA and PCA was better than those in the 3.0 T MR group, and there was no significant difference in the scores ( P>0.05), while the visualizations of proximal arteries in the 5.0 T MR group were significantly better than those in the 3.0 T MR group ( P<0.05). Furthermore, small vessel branches such as LA and PA in 5.0 T MR group were visualized better than those in 3.0 T MR group ( P<0.001). Conclusion:TOF-MRA by ultra-high filed 5.0-T provides an optimal choice in visualization of distal large arteries and small vessel branches, which could be useful for the diagnosis on cerebral vascular disease.
