Background: Gastrointestinal cancer is a significant cause of cancer incidence and mortality. Nevertheless, the epidemiology of the burden among adolescents and young adults (AYAs, aged 15-39 years) remains limited in the Asia-Pacific region, despite the region's significant population. This study aims to explore the gastrointestinal cancer burden among AYAs in the Asia-Pacific region for the year 2019, while also analysing trends from 1990 to 2019 and projecting future trends up to 2044., Methods: Annual case numbers, age-standardized rates of incidence, death, and disability-adjusted life-years (DALYs) and their estimated annual percentage changes (EAPCs) for gastrointestinal cancers were derived from the Global Burden of Disease, Injuries, and Risk Factors Study 2019. Trends over the next 25 years have also been predicted., Results: In 2019, there were 117,714 incident cases, 61,578 deaths and 3,483,053 DALYs due to gastrointestinal cancers in the Asia-Pacific region, accounting for 68.5%, 67.6% and 72.4%, respectively, of global gastrointestinal cancers in this population. The highest age-standardized rates occurred in countries with a middle Socio-demographic Index. From 1990 to 2019, there was a decline in the age-standardized rates of incidence, death and DALY attributed to gastrointestinal cancers, with EAPC of -1.10, -2.48 and -2.44, respectively. These rates are expected to stabilize over 25 years, with notable variations in individual gastrointestinal cancers., Conclusions: Gastrointestinal cancers among AYAs in the Asia-Pacific region have posed a significant burden over the past 30 years and are expected to persist in the coming years.

Background: The objective of this study is to conduct a temporal analysis of rheumatic heart disease (RHD) disease burden trends over a 30-year period (1991 to 2021), focusing on prevalence, deaths, and disability-adjusted life years (DALYs) in the South Asia (SA)., Methods: In this ecological study, we analyzed data regarding burden of RHD from the Global Burden of Diseases (GBD) study spanning the years 1991 to 2021 for the SA Region. Estimates of the number RHD-related prevalence, deaths, and DALYs along with age-standardized rates (ASR) per 100,000 population and 95% uncertainty intervals (UI) were evaluated., Results: The overall prevalent cases of RHD in the 2021 were 54785.1 × 10 3 (43328.4 × 10 3 to 67605.5 × 10 3 ), out of which 14378.8 × 10 3 (11206.9 × 10 3 to 18056.9 × 10 3 ) were from SA. The ASR of point prevalence showed upward trend between 1991 and 2021, at global level and for SA with an average annual percentage change (AAPC) of 0.40 (0.39 to 0.40) and 0.12 (0.11 to 0.13), respectively. The overall number of RHD-related deaths in the 2021 were 373.3 × 10 3 (324.1 × 10 3 to 444.8 × 10 3 ), out of which 215 × 10 3 (176.9 × 10 3 to 287.8 × 10 3 ) were from SA, representing 57.6% of the global deaths. The ASR of deaths also showed downward trend between 1991 and 2021, at global level and for SA with an AAPC of -2.66 (-2.70 to -2.63) and -2.07 (-2.14 to -2.00), respectively. The ASR of DALYs showed downward trend between 1990 and 2019, at global level and for South Asian region with an AAPC of -2.47 (-2.49 to -2.44) and -2.22 (-2.27 to -2.17), respectively., Conclusion: The rising age-standardized prevalence of RHD remains a global concern, especially in South Asia which contribute to over 50% of global RHD-related deaths. Encouragingly, declining trends in RHD-related deaths and DALYs hint at progress in RHD management and treatment on both a global and regional scale., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)
