  • Adhesive capsulitis (AC), or frozen shoulder, is a painful condition typically affecting people aged 40-60, and diagnosing it can be difficult due to its gradual onset and different stages.
  • A new scoring system was created to improve the diagnosis of AC, assessing factors like patient history, imaging results, and other health conditions.
  • This scoring system successfully categorized patients, helping to identify those with clear cases of AC, uncertain diagnoses, or excluded them from having the condition altogether, which could lead to better treatment strategies.

This study, employing an interim analysis, investigates the effects of the Dermamecum protocol, a structured educational and tailored approach that stratifies ostomy patients into risk paths (green, yellow, red) based on pre-operative and post-operative characteristics. The green path indicates a low risk of peristomal skin complications (PSCs), focusing on sustaining healthy behaviours and basic stoma care. The yellow path represents a moderate risk, emphasizing the need for patients to self-monitor and recognize early signs of complications.

Biomedical relation extraction from scientific publications is a key task in biomedical natural language processing (NLP) and can facilitate the creation of large knowledge bases, enable more efficient knowledge discovery, and accelerate evidence synthesis. In this paper, building upon our previous effort in the BioCreative VIII BioRED Track, we propose an enhanced end-to-end pipeline approach for biomedical relation extraction (RE) and novelty detection (ND) that effectively leverages existing datasets and integrates state-of-the-art deep learning methods. Our pipeline consists of four tasks performed sequentially: named entity recognition (NER), entity linking (EL), RE, and ND.
