AskGLP1: A Knowledge Graph LLM Agent for Exploring GLP-1 Experience from Online Patient Narratives

Read the original on arXiv AI →

AskGLP1 is a system that converts unstructured online patient narratives about GLP‑1 medications into a knowledge graph and uses an LLM‑assisted pipeline grounded in MedDRA terminology to answer questions about drug experiences. The pipeline screened nearly 8.5 million Reddit posts, distilled 163,135 relevant experiences, and combined them with 2,506 WebMD reviews into a KG containing 385,790 drug‑side‑effect and drug‑purpose relations. Analysis of the KG shows that online narratives highlight everyday burdens such as fatigue and food aversion, differ from FAERS reports in symptom emphasis, and reveal drug‑specific variations in reported side effects. whyItMatters":"The study uncovers gaps between formal pharmacovigilance data and patient‑reported experiences, underscoring the need for patient‑centered approaches to drug safety monitoring."

Knowledge-augmented Agentic AI for Mental Health Medication Information Seeking

arXiv:2606. 26205v1 Announce Type: new Abstract: Patients increasingly seek medication information online, yet safety knowledge for psychiatric drugs is split between regulatory adverse-event records, which are authoritative but abstract, and patient narratives, which are experience-near but unvalidated.

OpenAIs HealthBench in Action: Evaluating an LLM-Based Medical Assistant on Realistic Clinical Queries

arXiv:2509. 02594v3 Announce Type: replace-cross Abstract: Evaluating large language models (LLMs) on their ability to generate high-quality, accurate, situationally aware answers to clinical questions requires going beyond conventional benchmarks to assess how these systems behave in complex, high-stakes clinical scenarios.

Open Foundation Models in Healthcare: Challenges, Paradoxes, and Opportunities with GenAI Driven Personalized Prescription

The paper surveys open, non‑proprietary large language models (LLMs) and AI foundation models (AIFMs) for clinical use, presenting a taxonomy of current state‑of‑the‑art models. It empirically tests open‑weight LLMs on a personalized‑prescription task, finding that they match or surpass a proprietary baseline in overall suitability accuracy, especially when combined with Retrieval‑Augmented Generation (RAG). A subjective evaluation by blinded raters shows mixed effects of RAG on perceived suitability across multiple dimensions, and the authors discuss ethical risks and the need for responsible deployment.

Coupled Graph--Policy Distillation for Personalized Medication Safety in Older Adults with Multimorbidity

arXiv:2608. 09443v1 Announce Type: new Abstract: Large language model (LLM) agents can support medication review between clinical visits, but safe choices for older adults with multimorbidity depend on conditions, medications, and geriatric risks that users may omit.
