AI Article Synopsis
- A previous trial indicated that re-irradiation combined with chemotherapy improved disease-free survival in recurrent Head and Neck squamous-cell carcinoma (HNSCC) patients.
- The study compared two re-irradiation methods: a longer regimen with chemotherapy (VP-arm) and a shorter one with cetuximab (HFR-arm), focusing on treatment interruptions due to toxicity.
- Results showed that the HFR-arm had fewer treatment interruptions, with no significant difference in overall survival or disease-free survival between the two methods, indicating that the shorter regimen with cetuximab was well-tolerated.
Article Abstract
Background: A previous randomized trial in recurrent Head and Neck squamous-cell carcinoma (HNSCC) has shown re-irradiation combined with chemotherapy after salvage surgery significantly improved disease-free survival (DFS). The objective of this randomized trial was to compare two methods of re-irradiation in terms of toxicity and survival.
Patients And Methods: Patients with recurrence/second primary in previously irradiated area were randomly allocated to receive either 60 Gy over 11 weeks with concomitant 5FU - hydroxyurea (VP-arm), or 60 Gy (1.2 Gy twice daily) over 5 weeks with cetuximab (HFR-arm). Primary endpoint was treatment interruption >15 days (acute toxicity).
Results: Twenty-six patients were included in VP-arm and 27 in HFR-arm. One patient in VP-arm experienced >15 days interruption due to toxicity, and none in HFR-arm. In both arms, all patients received at least 60 Gy. In VP-arm, 8/26 patients had chemotherapy delay and/or dose reduction. In HFR-arm, 4/27 patients had <6 cycles cetuximab. There was no significant difference in overall survival (Median OS: 37.4 months vs 21.9 months, p = 0.12). Toxicities and DFS were not different between 2 arms.
Conclusions: Twice daily schedule of re-irradiation of 60 Gy/5 weeks with cetuximab was tolerable and no significant difference in treatment delays occurred between two arms.

Background: Research has shown that engaging in a range of healthy lifestyles or behavioral factors can help reduce the risk of developing dementia. Improved knowledge of modifiable risk factors for dementia may help engage people to reduce their risk, with beneficial impacts on individual and public health. Moreover, many guidelines emphasize the importance of providing education and web-based resources for dementia prevention.

Background: Postpartum depression remains a significant concern, posing substantial challenges to maternal well-being, infant health, and the mother-infant bond, particularly in the face of barriers to traditional support and interventions. Previous studies have shown that mobile health (mHealth) interventions offer an accessible means to facilitate early detection and management of mental health issues while at the same time promoting preventive care.
Objective: This study aims to evaluate the effectiveness of the Leveraging on Virtual Engagement for Maternal Understanding & Mood-enhancement (LoVE4MUM) mobile app, which was developed based on the principles of cognitive behavioral therapy and psychoeducation and serves as an intervention to prevent postpartum depression.

We evaluated enterocyte damage (IFABP), microbial translocation (sCD14), and inflammatory responses (TNF-α, IL-6, CRP) in 16 older adults (66-78 years) during 8 hours rest in conditions simulating homes maintained at 22°C (control), the 26°C indoor temperature upper limit proposed by health agencies, and homes without air-conditioning during heatwaves (31°C, 36°C). Relative to 22°C, IFABP was elevated ~181 pg/mL after exposure to 31°C (P=0.07), and by ~378 pg/mL (P<0.
