Efficacy of Cognitive Behavioural Therapy for Insomnia and Bright Light Therapy in Adolescents With ADHD, Insomnia, and Evening Chronotype

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by persistent inattention, hyperactivity, and impulsivity. In adolescents and young people, ADHD is commonly accompanied by insomnia and circadian delay. These co-occurring sleep and circadian disturbances may negatively affect daytime functioning and overall clinical outcomes. Although cognitive behavioural therapy for insomnia (CBT-I) is considered the first-line treatment for insomnia, and bright light therapy may help address circadian issues, their efficacy in adolescents with ADHD and comorbid insomnia and eveningness remains unexplored. This study aims to evaluate whether CBT-I, with or without bright light therapy, improves insomnia, sleep, and circadian as well as other clinical outcomes, and cognitive functioning in youths with ADHD and whether these interventions can also lead to improvements in mood and other clinical symptoms, as well as cognitive functioning.

Estimation and Prediction of Individual Benefit From Postoperative Adjuvant Transcatheter Arterial Chemoembolization For Patients With Hepatocellular Carcinoma

Adjuvant transarterial chemoembolization (TACE) is widely adopted in China for resectable hepatocellular carcinoma (HCC), yet its efficacy remains inconsistent. We aimed to identify factors influencing individual patient benefit using causal machine learning. To this end, we retrospectively collected HCC patients with high risk factors for tumor recurrence from four centers of China, divided into the discovery cohort and the validation cohort . The primary endpoint was disease-free survival (DFS). The primary endpoint was overall survival (OS).Individual treatment effects (ITEs) were estimated within a causal machine learning framework. An ITE \< 0 was considered recommendation for adjuvant TACE , while ITE ≥ 0 indicated active surveillance. The model would be validated in the validation cohort. The contribution of each variable to ITE was assessed using the Shapley Additive Explanations (SHAP). An online calculator would be developed for future use by public.

Early Intervention to Prevent Lower Limb Lymphedema of Gynecological Malignancy

This study is a prospective, randomized, controlled clinical trial of a single center in China and plans to enroll 400 patients. 1. Patients with diagnosed gynecological malignancies who underwent pelvic and abdominal lymphadenectomy and required pelvic radiotherapy; 2. Random grouping (A:B=3:1): A. Prophylactic lymphoedema treatment; B. Standard care group; 3. Preventive lymphedema health education was given to patients with gynecological malignant tumors without contraindications before surgery. All patients were randomly divided into an intervention group and a nonintervention group. The intervention group received preventive lymphedema treatment twice a week. 10 times, and the interval between the two treatments was not less than 48 hours and not more than 2 weeks. The intervention measures included four parts: manual lymphatic drainage, skin care, functional exercise, and wearing lymphedema preventive compression stockings. In the nonintervention group, knowledge education and telephone follow-up were routinely conducted. 4. All patients were evaluated for edema, lymphedema symptoms and quality of life 1 day before radiotherapy, every Friday during radiotherapy and every 3 months thereafter. Bioelectrical impedance measurement and leg diameter measurement were used to evaluate edema, the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) was used to evaluate lymphedema symptoms, and the EORTC Quality of Life Scale (QLQ-C30) was used to evaluate quality of life. followed up to 2 years after the end of lymphedema prophylaxis.
