The Declaration of Helsinki, established in 1964, remains a foundational document in medical research ethics. This review examines the 2024 revision, endorsed by the 75th World Medical Association (WMA) Assembly, highlighting its impact on modern clinical research. Major updates include the shift from "subjects" to "participants," promoting autonomy and active involvement, and the introduction of dual ethical review requirements for cross-border studies to strengthen accountability. ⋯ In response to global health crises such as COVID-19, the revised Declaration sets forth ethical protections to balance participant safety with research urgency during emergencies. Despite these advances, areas for improvement remain, especially in AI ethics, emergency research protocols, and the extension the Declaration's scope to include forensic and specimen research. The 2024 revision thus strengthens the Declaration's role as an adaptive, relevant framework for safeguarding participant rights and research integrity in a changing landscape.

Gastroesophageal reflux disease (GERD) is a chronic inflammatory gastrointestinal disease, which has no thoroughly effective or safe treatment. Elevated oxidative stress is a common consequence of chronic inflammatory conditions. ⋯ These findings offered strong support for the identification of GERD treatment targets in the future as well as for the study of the oxidative stress mechanism underlying GERD.

The mechanisms underlying osteoarthritis (OA) remain unclear, and effective treatments are lacking. This study aims to identify OA-related genes and explore their potential in drug repositioning for OA treatment. ⋯ This study identified potential OA-related genes and explored their roles in drug repositioning, suggesting the repurposing of existing drugs and the development of new therapeutic options for OA patients. Key message What is already known on this topic The exact pathogenesis of osteoarthritis (OA) remains unclear, and currently, there are no approved drugs that can prevent, halt, or inhibit the progression of OA. What this study adds We identified 128 OA-related genes and 10 core-related genes based on common biological processes revealed by TWAS and mRNA expression profiling. Using these genes, we discovered potential drugs for OA through the Network-based drug repositioning method. How this study might affect research, practice, or policy This study provides recommendations for repositioning existing drugs and developing new treatment options for patients with OA.

Observational studies have suggested a potential link between emotions and inflammatory dermatoses. However, research on the causal relationship between different types of emotions and inflammatory dermatoses is lacking. This study is aimed to investigate the causal relationship between negative emotions and inflammatory dermatoses through Mendelian randomization (MR) analysis. ⋯ This MR study revealed bidirectional causality between worrier/anxious feelings and eczema. It also found that guilty feelings may elevate the risk of psoriasis, and individuals with psoriasis may experience increased rates of miserableness, worrier/anxious feelings, nervous feelings, and loneliness/isolation.
