Background: Early identification of intravenous immunoglobulin (IVIG) resistance contributes to better management of Kawasaki disease (KD). This study aims to establish an effective prediction model for IVIG resistance in the Chinese population. Methods: A total of 658 eligible patients diagnosed with KD were enrolled in this study, with 461 in the training cohort and 197 in the validation cohort. The demographic characteristics and potential risk factors were compared between IVIG-responsive and resistant groups. Predictors were selected by the Akaike information criterion. The nomogram's performance was evaluated by calibration curve, decision curve analysis, and operating characteristic curve. Results: White blood cell counts (WBC), neutrophil-lymphocyte ratio (N/L ratio), hematocrit (HCT), albumin (ALB), total bilirubin (TBIL), lactate dehydrogenase (LDH), and creatinine (Cr) were detected as predictors of IVIG resistance. A predictive nomogram incorporating these predictors was constructed using the training cohort. The calibration curve and decision curve analysis showed good discrimination and calibration of the proposed nomogram in both training and validation sets, and the area under the receiver operating characteristic curve (AUROC) in both sets was 75.8% and 74.2%, respectively. Conclusion: This study identified WBC, N/L ratio, HCT, ALB, TBIL, LDH, and Cr as predictors for IVIG resistance in patients with KD. The proposed novel nomogram with a high level of accuracy and reliability may benefit clinical decision-making upon treatment initiation. [ABSTRACT FROM AUTHOR]

Background: Narcissistic personality disorder (NPD) has never been applied in Chinese clinical practice, and the distribution of NPD in the clinical population of China is largely unknown. The current study uses two-stage clinic-based screening to investigate the frequency and clinical features of NPD in a Chinese help-seeking sample. Methods: A total of 1402 consecutive outpatients ages 18–60 were recruited during their visit to the Shanghai Mental Health Center and screened with the Personality Diagnostic Questionnaire Fourth Edition Plus (PDQ-4+) and Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) Axis II (SCID-II). The structured clinical interview was administered to estimate the rate of NPD and the frequency of each disorder criterion. Results: The frequency estimate of NPD in the total sample was 4.0%. Among the 56 outpatients who met the criteria for NPD, there were more males than females, and many had a better educational background. The SCID-II interviews revealed high frequencies of diagnostic criterion 1 ("exaggerated sense of self-importance. NPD likely overlaps with Histrionic PD, Borderline PD, and Paranoid PD. This two stage screening method can enhance detection of Chinese NPD patients in clinical settings. Conclusions: Narcissism pathology is not rare in the Chinese psychiatric community when using the DSM-IV NPD criteria. Existing evidence suggests, at least indirectly, that there are important benefits of NPD diagnosis in psychiatric practice. [ABSTRACT FROM AUTHOR]

Background/objective: This multicenter study aimed to explore the efficacy and toxicity of radioactive Iodine-125 seed implantation for lymph node recurrence in patients with esophageal cancer after external radiotherapy. Methods: Clinical data of eligible patients from 5 centers in China were retrospectively reviewed. A total of 126 patients between January 2016 and March 2019 were included. The median interval between previous radiotherapy and radioactive Iodine-125 seed implantation was calculated. The target volume was 2.1–128.1 cm3 (median, 22.2 cm3) and the median postoperative D90 is 120.6 Gy (range, 101.7–192). Short-term efficacy of tumor response, the long-term efficacy of local progression-free survival (LRFS) and overall survival (OS), and treatment-related toxicity were reported. Results: For tumor response, 37 (29.4%), 51 (40.5%), 14 (11.1%), and 24 (19.0%) patients achieved complete response, partial response, stable disease and progressive disease, respectively. The 1-, 2- and 3-year LPFS and OS rates were 48.8%, 23.0% and 15.9%, and 80.2%, 38.8%, and 24.5%, respectively. Multivariate analysis identified Karnofsky performance status (P = 0.041) and tumor response (P = 0.049) as independent prognostic factors for LPFS; initial tumor stage (P = 0.034), lesion volume (P = 0.017), and tumor response (P = 0.004) as independent prognostic factors for OS. In total, 77 (61.1%) patients suffered from skin reactions and the incidence of grade 3–5 skin toxicity was 5.6% (7/126). Conclusion: Radioactive Iodine-125 seed implantation seems efficient with acceptable toxicity for the treatment of lymph node recurrence secondary to esophageal cancer. A head-to-head study is needed to further evaluate the survival benefit. [ABSTRACT FROM AUTHOR]
