Article Abstract

This study introduces NeuMANTA (Multifunctional Arithmetic for Neutron Transportation Analysis), a dedicated treatment planning system (TPS) developed for accelerator-based boron neutron capture therapy (AB-BNCT). NeuMANTA integrates Monte Carlo-based dose calculation with modular workflow management to enable full-cycle support from imaging to post-treatment verification. Powered by the BNCT-specific COMPASS (COMpact PArticle Simulation System) engine, the system achieves dosimetric accuracy comparable to MCNP while reducing computation time by 2.8-fold. NeuMANTA supports heterogeneous boron distribution modeling, automated multi-scenario dose calculations based on measured blood boron concentrations, and polynomial dose-rate response fitting. It also enables seamless data exchange with external systems including patient positioning, boron measuring, and beam control via a dedicated radiotherapy data management system (RDMS). A clinical demonstration using the NeuPex platform in China's first investigator-initiated AB-BNCT trial validated the system's feasibility, accuracy, and clinical interoperability. These results highlight NeuMANTA's potential as a standardized platform for precision BNCT, offering reliable dose planning, adaptive delivery, and robust system integration.

Diabetes management during the end of life.

For individuals with diabetes, maintaining optimal glycaemic control is essential to reduce the risk of long-term complications. However, as patients approach the end of life, the emphasis on tight glycaemic targets becomes less relevant. Instead, the primary goal shifts to maintaining blood glucose levels within a range that minimises the risk of hypoglycaemia and prevents symptomatic hyperglycaemia, thereby ensuring comfort and quality of life.

Background: Epigenetic regulation significantly affects immune responses in lung adenocarcinoma (LUAD). However, the role of RNA N6-methyladenosine (m6A) modification, especially in obstructive sleep apnea-hypopnea syndrome (OSAHS) within LUAD, is not well understood.

Methods: This study examined m6A modification patterns in 973 LUAD patients using 23 regulatory genes.
