Global, regional, and national burden of ischemic stroke, 1990-2021: an analysis of data from the global burden of disease study 2021.

Ischemic stroke remains a major contributor to global mortality and morbidity. This study aims to provide an updated assessment of rates in ischemic stroke prevalence, incidence, mortality, and disability-adjusted life-years (DALYs) from 1990 to 2021, specifically focusing on including prevalence investigation alongside other measures. The analysis is stratified by sex, age, and socio-demographic index (SDI) at global, regional, and national levels. Data for this study was obtained from the 2021 Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). To quantify temporal patterns and assess trends in age-standardized rates of ischemic stroke prevalence (ASPR), incidence (ASIR), mortality (ASDR), and DALYs, estimated annual percentage changes (EAPCs) were computed over the study period. The analyses were disaggregated by gender, 20 age categories, 21 GBD regions, 204 nations/territories, and 5 SDI quintiles. R statistical package V 4.4.2 was performed for statistical analyses and plot illustrations. In 2021, the global burden of ischemic stroke remained substantial, with a total of 69,944,884.8 cases with an ASPR of 819.5 cases per 100,000 individuals (95% UI: 760.3-878.7). The ASIR was 92.4 per 100,000 people (95% UI: 79.8-105.8), while the ASDR was 44.2 per 100,000 persons (95% UI: 39.3-47.8). Additionally, the age-standardized DALY rate was 837.4 per 100,000 individuals (95% UI: 763.7-905). Regionally, areas with high-middle SDI exhibited the greatest ASPR, ASIR, ASDR, and age-standardized DALY rates, whereas high SDI regions had the lowest rates. Geospatially, Southern Sub-Saharan Africa had the highest ASPR, while Eastern Europe showed the highest ASIR. The greatest ASDR and age-standardized DALY rates were observed in Eastern Europe, Central Asia, as well as North Africa, and the Middle East. Among countries, Ghana had the highest ASPR, and North Macedonia had both the highest ASIR and ASDR. Furthermore, North Macedonia also exhibited the highest age-standardized DALY rate. Regions with high-middle and middle SDI continued to experience elevated ASPR, ASIR, ASDR and age-standardized DALY rates. The highest ischemic stroke burden was observed in Southern Sub-Saharan Africa, Central Asia, Eastern Europe, and the Middle East. None.

Global, Regional, and National Burden of Ischemic Stroke, 1990-2019.

To the best of our knowledge, no comprehensive update of the descriptive epidemiology and trends of ischemic stroke has been released since Global Burden of Disease (GBD) 2017. Thus, our objective was to examine ischemic stroke burden at the global, regional, and national levels in terms of sex, age, and social development index (SDI). Data were extracted from the GBD 2019 datasets. Estimated annual percentage changes (EAPCs) were calculated to assess the incidence rate, mortality, and disability-adjusted life-years (DALY) trends of ischemic stroke. Measures were stratified by sex, region, country, age, and SDI. The global age-standardized incidence rate (ASIR) of ischemic stroke decreased from 1990 to 2019, with an EAPC of -0.43 (95% confidence interval [CI] -0.54 to -0.32). High-middle and middle SDI regions had much higher ASIR, age-standardized death rate (ASDR), and age-standardized DALY rates due to ischemic stroke than other SDI regions. Regionally, East Asia had the highest ASIR of ischemic stroke in 2019 and the largest increase in the ASIR from 1990 to 2019. Nationally, Egypt (EAPC 1.40, 95% CI 1.27-1.52) and China (EAPC 1.10, 95% CI 1.00-1.20) had the most pronounced increases in the ASIR of ischemic stroke. Globally, there was an increase in ischemic stroke incidence with increasing age, especially in women 50 to 69 years of age or older. The global ASDR decreased from 1990 to 2019, with an EAPC of -1.63 (95% CI -1.72 to -1.53). The ASDR and age-standardized DALY rates increased most in southern sub-Saharan Africa, eastern sub-Saharan Africa, and southeast Asia. The ASIR, ASDR, and age-standardized DALY rates remained high in high-middle and middle SDI regions. East Asia, southern sub-Saharan Africa, eastern sub-Saharan Africa, and Southeast Asia had the greatest burden of ischemic stroke.

Burden of esophageal cancer between 2010 and 2019 in Asian countries by geographical region and sociodemographic index: A comparison with global data.

The aim of this study was to describe the trends in incidence, mortality, and burden of esophageal cancer (EC) in Asia from 2010 through 2019 and compare with other global continental data. We collected EC data from the 2019 Global Burden of Disease study from 2010 to 2019 in 49 countries and territories in Asia based on the sociodemographic index (SDI). For all locations, annual case data and age-standardized rates (ASRs) were extracted to investigate the EC incidence, prevalence, mortality, and disability-adjusted life-years (DALYs). The ASR relative difference (%) between years and the male/female (M/F) ratio were calculated. Data are reported in values and 95% uncertainty interval (UI). In 2019, more than 70% of EC new cases, deaths, prevalence, and DALYs occurred in Asian countries. From 2010 to 2019, incidences, deaths, prevalence cases, and DALY number of EC increased over 1.10-, 1.07-, 1.14-, and 1.03-fold, in Asia. During this period, the age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), age-standardized prevalence rate (ASPR), and age-standardized DALYs rate (DALYs ASR) of EC decreased by 18, 21, 14, and 22%, respectively. The rate of decline in Asia is higher than in the world and other continents. In 2019, age-specific incidence, death, prevalence, and DALY cases of EC cancer peaked at 65-74, 70-74, 65-69, and 65-69 years, respectively. In 2019, the highest ASIR, ASDR, ASPR, and DALYs ASR of EC were observed in East Asian countries, while having the highest decreasing trend. In 2019, among high SDI Asian countries, Taiwan had the highest ASIR, ASPR, and DALYs ASR, and the United Arab Emirates had the highest ASDR. Among high-middle SDIs, Kazakhstan had the highest ASIR, ASPR, ASDR, and DALYs ASR; among middle SDIs, China had the highest ASIR, ASDR, and ASPR, and Viet Nam had the highest DALYs ASR; among low-middle SDIs, Mongolia had the highest ASIR, ASDR, ASPR, and DALY ASR of EC cancer. Among low SDI Asian countries, Pakistan had the highest ASIR and ASPR, and DALY ASR for EC cancer. For four indicators, in most countries, the ratio of men was higher than women, and in some countries, this ratio reached more than 10 times. Although the rate of decline in incidence, death, prevalence and burden of EC in Asia was higher than in other areas in the last 10 years, more than 70% of these amounts occur in Asia. Therefore, it appears that adopting appropriate strategies in the field of identifying and controlling modifiable risk factors for EC, implementing screening programs, and timely diagnosis and treatment will help in reducing the burden of this disease in Asian countries.

Temporal trends of tracheal, bronchus, and lung cancer between 2010 and 2019, in Asian countries by geographical region and sociodemographic index, comparison with global data.

This study aimed to describe the trends in incidence, mortality, and burden of tracheal, bronchial and lung (TBL) cancer in Asia from 2010 through 2019 and compare with global and other continental data. We collected TBL cancer data from the 2019 Global Burden of Disease (GBD) study from 2010 to 2019 in 49 countries and territories in Asia. For all locations, annual case data and age-standardized rates (ASRs) were used to investigate the incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) of TBL from 2010 to 2019. The relative difference (%) between years was used to show comparative variations of ASRs for the indicators studied. In 2019, more than 55% of TBL cancer cases and deaths occurred in Asian countries. A total of 57% of lung cancer patients lived in Asia and almost 60% of the global burden of lung cancer was imposed on Asian countries. From 2010 to 2019, incidences, deaths, prevalence cases, and DALYs number of TBL cancer increased over 1.34-, 1.31-, 1.31-, and 1.26-fold, in Asia. During this period, the age-standardized incidence rate (ASIR), the age-standardized death rate (ASDR), the age-standardized prevalence rate (ASPR), and the age-standardized DALYs rate (DALYs ASR) of TBL cancer decreased by 1, 3, 4, and 4%, respectively. While at the same time, the decreasing trend of these rates globally and in America and in Europe happened faster. In 2019, age-specific incidence, death, prevalence, and DALY cases of TBL cancer were peaking at 65-74, 70-74, 65-69, and 65-69 years, respectively. In 2019, the highest ASIR, ASDR, and DALYs ASR of TBL cancer was observed in East Asia countries and the highest ASPR in high-income Asia Pacific countries. Central Asia and high-income Asia Pacific countries experienced a decreasing trend in ASIR and ASDR, and the South Asia countries experienced the highest increasing trend from 2010 to 2019. ASPR only decreased in Central Asia, and DALYs ASR only increased in South Asia. In 2019, among high sociodemographic index (SDI) Asian countries, Brunei Darussalam had the highest ASIR, ASDR, and DALYs ASR and the Republic of Korea had the highest ASPR. Among high-middle SDIs, Turkey and Georgia; among middle SDIs, China and Armenia; among low-middle SDIs, Mongolia and the Democratic People's Republic of Korea had the highest ASIR, ASDR, ASPR, and DALY ASR of TBL cancer. Among low SDI Asian countries, Pakistan had the highest ASIR, ASDR, ASPR, and DALY ASR of TBL cancer. Most of the global burden of lung cancer occurs in Asian countries, and the decreasing trend of incidence, death, prevalence, and burden of this cancer in these countries is slower than in other regions. Therefore, the implementation of necessary measures in order to reduce the process of this cancer is considered urgent.
