Objective:To construct a risk prediction model for non-suicidal self-injury (NSSI) in adolescents with mood disorders, providing a basis for identifying and intervening in high-risk patients.Methods:A convenience sampling method was used to retrospectively analyze 724 adolescent patients with mood disorders admitted to the open ward of Qingdao Mental Health Center from January 2019 to July 2023. Patients admitted from January 2019 to December 2022 (641 cases) were randomly divided into a modeling group and an internal validation group in a 7∶3 ratio, while patients admitted from January to July 2023 (83 cases) were used as an external validation group. A binary multivariate logistic regression analysis was used to construct a nomogram prediction model for NSSI risk in adolescents with mood disorders. The predictive performance of the model was evaluated using the area under the curve (AUC), sensitivity, and specificity.Results:There were 179 males and 545 females, aged 15 (14, 17) years old. Among the 724 patients, 449 were in the modeling group, 192 in the internal validation group, and 83 in the external validation group. The incidence of NSSI in the modeling group was 32.96% (148/449). Reduced food intake ( OR=10.980, 95% CI 4.462-27.017), passive contact ( OR=4.681, 95% CI 1.986-11.031), Hamilton Depression Rating Scale-17 score >17 ( OR=12.235, 95% CI 4.657-32.141), Hamilton Anxiety Rating Scale score>15 ( OR=27.888, 95% CI 8.700-124.630), Insomnia Severity Index score >15 ( OR=6.357, 95% CI 2.257-17.899), and higher levels of past self-injury ( OR=1.663, 95% CI 1.428-1.935) were independent risk factors for NSSI in adolescents with mood disorders (all P<0.05). The AUC of the nomogram model based on these six factors was 0.973, with a sensitivity of 0.94 and a specificity of 0.89. Conclusions:The risk prediction model for NSSI in adolescents with mood disorders has good discrimination, accuracy, and practicality, and can help identify high-risk NSSI populations among adolescents with mood disorders.

Objective To explore the clinical value of high frequency ultrasound combined with dermoscopy in preoperative evaluation of cutaneous malignant tumors.Methods A total of 323 patients with suspected cutaneous malignant tumors were selected from Jinhua Municipal Central Hospital from January 2022 to December 2023.The clinical value of high frequency ultrasound,dermoscopy and their combined examination in preoperative diagnosis of cutaneous malignant tumors were analyzed and compared.Results A total of 323 patients with suspected cutaneous malignant tumors,223 patients with confirmed cutaneous malignant tumors by skin pathology,234 skin lesions,and 100 patients with benign skin tumors were included.141 skin lesions were detected by dermoscopy,195 skin lesions by high frequency ultrasound,and 213 skin lesions by the combination of dermoscopy and high frequency ultrasound.The sensitivity,specificity and accuracy of high frequency ultrasound combined with dermoscopy in diagnosis of cutaneous malignant tumors were 87.6％,92.0％and 88.9％,respectively,which was higher than that of single high frequency ultrasound and single dermoscopy.The diagnosis results of dermoscopy combined with high frequency ultrasound were in good agreement with the pathological results(kappa=0.75).Conclusion Dermoscopy and high frequency ultrasound are convenient,non-invasive and sensitive imaging methods for skin detection.They can balance resolution and depth of detection,reveal morphological information of tumors,and predict the risk of tumor recurrence.

Objective To identify the impact of glucose variability(GV)on the development of gestational hyper-tension(GH)in patients with gestational diabetes mellitus(GDM),and to find the differences between various GV metrics as well as to evaluate their predictive value in management strategy development.Methods A total of 127 pregnant women diagnosed with GDM were included in this study.After the diagnosis of GDM,continuous glu-cose monitoring(CGM)and blood pressure measurements were performed,and the occurrence of gestational hyper-tensive disorders was recorded.Indices of glucose variability were calculated using an automated software EasyGV version 9.0.Results The results revealed an association between gestational hypertension and glucose variability in GDM patients.Among the study participants,2 cases(1.6％)were diagnosed with preeclampsia and 9 cases(7.1％)were diagnosed with gestational hypertension.TBR％(time below range)showed a significantly negative correlation with diastolic blood pressure at 29-32 weeks of gestation and with both diastolic and systolic blood pres-sure during delivery.TIR％(time in range)showed a negative correlation with the rate of change in systolic blood pressure between two prenatal visits.CONGA(continuous overlapping net glycemic action)emerged as an inde-pendent predictor of gestational hypertension(OR:3.648;95％CI:1.046,12.721;P=0.042).When CONGA exceeded 4.856,the risk of gestational hypertension in GDM patients increased.Conclusions Blood glucose varia-tion is an independent factor affecting the occurrence of pregnancy-induced hypertension in GDM women.This study suggests new targets for the use and management of CGM in pregnant women with GDM.For GDM patients at high risk of hypertensive disease during pregnancy,blood glucose should be kept at a reasonable and stable level.

Objective To evaluate the clinical value of a modified Cancer and Aging Research Group(CARG)model in guiding anticancer drug dose adjustments for elderly cancer patients in China.Methods This prospective study enrolled patients aged≥65 years with solid tumors at the Department of Oncology,Peking Union Medical College Hospital from September 1,2022 to October 29,2023.All patients underwent comprehensive geriatric assessment(CGA)and CARG risk scoring,and were stratified into low-,intermediate-,and high-risk groups.Anti-cancer drug doses(including chemotherapy,targeted therapy or immunotherapy)were reduced proportionally based on CARG risk stratification and treatment intent(curative vs.palliative).Treatment outcomes and adverse events(AEs)were recorded regularly.Fisher's Exact Test compared AE incidence between the CARG-guided dose adjust-ment group(experimental)and the physician-experience-guided dose adjustment group(control).Receiver operating characteristic(ROC)curve analysis was used to assess the predictive value of the CARG model for severe toxicity.Results Among 166 enrolled patients(median age:71 years[range:65-90];78.3%were male;68.7%had gastro-intestinal cancers;69.3%had stageⅣ),95 were assigned to the experimental group(CARG low-risk:24[25.3%],intermediate-risk:51[53.7%],high-risk:20[21.0%])and 71 were included into the control group.By December 31,2024,81 patients experienced disease progression and 10 patients died.Overall AE rates was 92.6%in the ex-perimental group and 94.4%in the control group,while grade≥3 AEs were recorded in 45.3%vs.43.7%,respec-tively(both P＞0.05).Conclusions The modified CARG model-guided dose adjustment strategy achieved comparable safety to empirical dose adjustment,which is in line with the individualized treatment paradigm for elderly cancer pa-tients,representing a structured framework for optimizing therapeutic decision-making in geriatric oncology.
