Burden of biliary tract carcinoma in China (1990-2021): Findings from the 2021 Global Burden of Disease Study.

Biliary tract carcinoma (BTC) is a group of malignant tumors that originate in the digestive system and occurs with a high incidence in China. Few consistent and comparable assessments of BTC disease burden have been conducted at national or subnational levels, and little is known about the demographic, temporal, and geographic patterns of epidemiological characteristics and disease burden of BTC in China. The incidence, mortality, disability-adjusted life-years (DALYs), years of life lost (YLLs) due to premature death and years lived with disability (YLDs) of BTC were comprehensively examined by age, sex, and calendar year in the Chinese population, using the methodological framework and analytical strategies used for the 2021 Global Burden of Disease study.

Mortality and years of life lost of colorectal cancer in China, 2005-2020: findings from the national mortality surveillance system.

Background: Colorectal cancer (CRC) is the fourth cause of cancer death in China. We aimed to provide national and subnational estimates and changes of CRC premature mortality burden during 2005-2020.

Methods: Data from multi-source on the basis of the national surveillance mortality system were used to estimate mortality and years of life lost (YLL) of CRC in the Chinese population during 2005-2020.

COVID-19 seeding time and doubling time model: an early epidemic risk assessment tool.

Background: As COVID-19 makes its way around the globe, each nation must decide when and how to respond. Yet many knowledge gaps persist, and many countries lack the capacity to develop complex models to assess risk and response. This paper aimed to meet this need by developing a model that uses case reporting data as input and provides a four-tiered risk assessment output.
