Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.

Objective To elucidate the clinical and pathological characteristics of patients with mercury poisoning-associated glomerulonephropathy. Methods Seven patients with mercury poisoning-associated glomerulonephropathy were enrolled in this study. The pattern of mercury exposure, feature of mercury toxicity, and clinicopathological presentation of the kidneys were investigated. Results They were all female, averaged (28.9 ±8.1) years old. Skin-whitening cream was the only cause of mercury poisoning. Proteinuria occurred 5 to 8 months after exposure. Serum mercury were 27.0 to 98.0 μg/L, and spot urinary mercury were 34.4 to 204.0 μg/L. The presentation of all the patients was mild to moderate edema with proteinuria and decreased serum albumin level. Five patients (5/7) were diagnosed as nephrotic syndrome. Six patients underwent renal biopsy: 3 cases with minimal change disease, 2 cases with membranous nephropathy and 1 case with focal segmental glomerular sclerosis. All the patients were administrated chelation therapy with sodium dimercaptopropanal sulfonate or sodium dimercaptosuccinic acid for 3 to 7 courses. They got complete remission by 3 to 5 weeks treatment. Conclusions Patients in this study with glomerulonephropathy induced by mercury poisoning are all from skin-whitening cream exposure. Mild to moderate edema and proteinuria are the common clinical pattern. Minimal change disease, membranous nephropathy and focal segmental glomerular sclerosis are found pathologically. Chelation therapy is effective.
