Changes of campus tobacco control environment and the impact on tobacco control behaviors among secondary school personnel in Shanghai, China.

Introduction: Youth smoking is a serious public health problem. Nevertheless, a rigorous tobacco-free environment within schools, combined with exemplary tobacco control behavior among school personnel can effectively contribute to reducing adolescent smoking. This study compared the tobacco control environment in Shanghai secondary schools in 2017 and 2021, and explored how the tobacco control environment influenced the tobacco control behaviors of school personnel.

Radiomics Based on Multimodal magnetic resonance imaging for the Differential Diagnosis of Benign and Malignant Vertebral Compression Fractures.

Objectives: Recent studies have indicated that radiomics may have excellent performance and clinical application prospects in the differential diagnosis of benign and malignant vertebral compression fractures (VCFs). However, multimodal magnetic resonance imaging (MRI)-based radiomics model is rarely used in the differential diagnosis of benign and malignant VCFs, and is limited to lumbar. Herein, this study intends to develop and validate MRI radiomics models for differential diagnoses of benign and malignant VCFs in patients.
