Background: In Hong Kong, breast cancer is the commonest female cancer. In addition to intrinsic risk factors that cannot be modified, other factors may be potentially modifiable. The objective of this report was to determine modifiable risk factors in association with breast cancer among Chinese women in our locality.

Purpose: To assess the diagnostic utility of MRI radiomics in the differentiation of musculoskeletal myxomas and myxoid sarcomas.
Study Type: Retrospective.
Long-term use of low-dose aspirin has been demonstrated to reduce cancer risk, but the duration of necessary medication use remains uncertain. This study aimed to investigate the long-term chemoprotective effect of aspirin among the Chinese population. This population-based study included all aspirin users between 2000 and 2019.

Silicon-rich nitride (SRN) was chosen as the material platform due to its high refractive index, CMOS compatibility, and cost-effective fabrication. Two SRN-based metalenses were designed: a geometric phase metalens (GPM) and a propagation phase metalens (PPM), each evaluated at aspect ratios of 10:1 and 4:1.

A challenge to the development of effective injury prevention interventions is the limited study pool of detailed activity and outcome data to provide better understanding of the characteristics of injurious events.
Methods: A cross-sectional study of individuals under 16 years of age hospitalised after TPI from November 2018 to December 2021 was conducted.
