Artificial Intelligence for Predicting Lymph Node Metastasis in Prostate Cancer: An evidence-based analysis of Machine Learning and Deep Learning Using CT and MRI

This meta-analysis of 21 studies demonstrates that while both machine learning and deep learning models achieve excellent diagnostic accuracy for predicting lymph node metastasis in prostate cancer, their optimal performance depends on a specific algorithm-modality pairing, with deep learning excelling on MRI data and machine learning performing better on CT data.

Analysis of Water Quality Characteristics and Pollution Sources in Different Water Seasons of Small Watersheds in Hilly and Mountainous Areas—Taking the Binan River Basin in Bishan District as an Example

This study analyzes the water quality characteristics and pollution sources of the Binan River Basin in Bishan District using a PMF model, revealing that nitrogen pollution is the primary contaminant, water quality deteriorates during the dry season, and agricultural runoff is the dominant source, thereby providing a scientific basis for seasonal and source-specific watershed management strategies.

Task-based exposure assessment of noise in patrol police officers using task-attributable fraction metrics

This study of 44 Seoul patrol officers demonstrates that while full-shift noise levels remain within occupational limits, intermittent high-intensity dispatch-related tasks disproportionately drive cumulative sound energy, highlighting the value of task-attributable fraction metrics for more effective noise exposure assessment and prevention.

Plasma TMAO Levels in Relation to Perioperative Venous Thromboembolism in Patients With Gynecological Malignancies: A Nested Case–Control Study

This nested case-control study of 981 patients undergoing gynecological cancer surgery found no statistically significant association between plasma TMAO levels and the risk of perioperative venous thromboembolism, suggesting that larger multicenter studies are needed to clarify the potential role of gut microbiota metabolites in tumor-associated thrombosis.

Fostering multidimensional learning engagement through generative AI in Chinese L2 writing: A quasi-experimental investigation grounded in self-determination theory

This quasi-experimental study grounded in self-determination theory demonstrates that teacher-facilitated integration of generative AI tools significantly enhances behavioral engagement and helps sustain cognitive and emotional engagement among Chinese as a second language learners, whereas conventional instruction leads to declines in these areas.

Psychosocial Stressors as Risk Factors for Prenatal Cannabis Use: A Multilevel Analysis of U.S. PRAMS Data, 2016–2022

This multilevel analysis of U.S. PRAMS data from 2016–2022 reveals that psychosocial stressors, concurrent substance use, and residence in states with recreational cannabis legalization are significant risk factors for prenatal cannabis use, while higher socioeconomic status serves as a protective factor.

Personality Traits and Social Participation among Community-Dwelling Older Adults in China: The Mediating Role of Perceived Emotional Needs

This study of 1,332 community-dwelling older adults in China reveals that perceived emotional needs partially mediate the relationship between specific personality traits (extraversion, agreeableness, conscientiousness, and neuroticism) and social participation, highlighting the psychological mechanisms through which personality influences social engagement in later life.
