Disability-adjusted life years and the trends of the burden of colorectal cancer:a population-based study in Shanghai,China during 2002 to 2016

Background:Colorectal cancer(CRC)still ranks the top in morbidity and mortality of cancers worldwide,posing a huge threat and burden to the society.We aimed to determine the age-standardized incidence,mortality,and disability-adjusted life years(DALYs)of CRC and explore potential changes in the temporal trends of the CRC burden in Shanghai during 2002 to 2016.Methods:The cancer statistics and demographics were obtained from the Cancer Registry and the Statistics Bureau of Pudong New Area,respectively.Data from 2002 to 2016 were included and analyzed retrospectively.DALYs were calculated using DisMod and the age-standardized rates(ASRs)were obtained according to Segi world standard population.Joinpoint regression was used to measure the trends in CRC incidence and to estimate the annual percent change.Results:The increasing trend of CRC ASR incidence halted after 2014,coinciding with the introduction of the Shanghai CRC screening program.The ASRs of mortality and DALYs increased,at 0.42%(P<0.05)and 4.07%(P<0.001)per year,respectively,which were mainly driven by men and individuals aged above the CRC screening program target.Conclusions:The disease burden of CRC in Shanghai remains serious,especially among men,and individuals aged>74 years.The benefits of the screening program have been partially proven by the ASRs of CRC incidence,providing important insights into better and wider application of screening programs.

Analysis of the Global Burden of Disease study highlights the trends in death and disability-adjusted life years of leukemia from 1990 to 2017

Background:The patterns of leukemia burden have dramatically changed in recent years.This study aimed to estimate the global trends of leukemiarelated death and disability-adjusted life-years(DALYs)from 1990 to 2017.Methods:The data was acquired from the latest version of the Global Burden of Disease(GBD)study.Estimated annual percentage changes(EAPCs)were calculated to estimate the trend of age-standardized rate(ASR)of death and DALYs due to leukemia and its main subtypes from 1990 to 2017.Results:Globally,the numbers of death and DALYs due to leukemia were 347.58×10^(3)(95%uncertainty interval[UI]=317.26×10^(3)-364.88×10^(3))and 11975.35×10^(3)(95%UI=10749.15×10^(3)-12793.58×10^(3))in 2017,with a 31.22% and 0.03% increase in absolute numbers from 1990 to 2017,respectively.Both of their ASR showed decreasing trends from 1990 to 2017 with the EAPCs being−1.04(95%confidence interval[CI]=(−1.10-−0.99)and−1.52(95%CI=−1.59-−1.44),respectively.Globally,the most pronounced decreasing trend of death and DALYs occurred in chronic myeloid leukemia with EAPCs of−2.76(95%CI=−2.88-−2.64)and−2.84(95%CI=−2.97-−2.70),respectively,while the trend increased in acute myeloid leukemia.The death and DALYs of leukemia decreased in most areas and countries with high socio-demographic index(SDI)including Bahrain,Finland,and Australia.Conclusions:The disease burden of death and DALYs due to leukemia decreased globally,and for most regions and countries from 1990 to 2017.However,the leukemia burden is still a substantial challenge globally and required adequate and affordable medical resources to improve the survival and quality of life of leukemia patients.

Burden of road traffic accidents in Nepal by calculating disability-adjusted life years

Objective:To calculate the burden of road traffic accidents in Kathmandu Valley and then extrapolate this to the national level.Methods:A prospective study was performed to compute the burden of road traffic accidents by quantification of disability-adjusted life years(DALYs)using the Global Burden of Disease Study method on the basis of 1-year data from nine hospitals in Nepal and the Department of Foren-sic Medicine and cross-checked with the Nepal Traffic Directorate.Multiple methods were applied to the extrapolated population metrics of the burden of road traffic accidents in Nepal.Results:The total number of years of life lived in disability,years of life lost,and DALYs in Nepal were 38,848±194,119,935±1464,and 158,783±1658(95% confidence interval)re-spectively.The number of years lost because of morbidity and death was similar in Kathmandu Valley.Most(75%)of the DALYs resulted from years of life lost in Nepal.Males accounted for 73% of DALYs.Almost half(44%)of the DALYs were contributed by the group aged 15-29 years.Conclusion:This study is the first to calculate the burden of road traffic accidents in Nepal using Nepal’s own data.Nepal needs to develop and enhance its own system to identify significant public health issues so as to set national priorities for prevention of road traffic accidents.

Esophageal cancer global burden profiles, trends, and contributors

Objective:This study aimed to provide a comprehensive overview of the global burden of esophageal cancer(EC)and determine the temporal trends and factors influencing changes in the global burden.Methods:The latest incidence and mortality data for EC worldwide were obtained from GLOBALCAN 2022.The mortality and disability-adjusted life years(DALYs)rates for EC from 1990±2019 were sourced from the 2019 Global Burden of Diseases.Trends in EC mortality and DALYs attributable to 11 risk factors or clusters of risk were analyzed using the joinpoint regression model.The trends in age-related EC burden were assessed using a decomposition approach.Results:An estimated 511,054 new cases of EC were diagnosed in 2022 with 445,391 deaths worldwide.Approximately 75%of cases and deaths occurred in Asia.Nearly 50%of global EC deaths and DALYs were attributed to tobacco use in men in 2019,while 20%were attributed to high body mass index(BMI)in women.From 1990±2019,EC deaths and DALYs attributable to almost all risk factors had declining trends,while EC deaths and DALYs attributed to high BMI in men had upward trends.The age-related EC burden exhibited an upward trend driven by population growth and aging,which contributed to 307.4 thousand deaths and 7.2 million DALYs due to EC.Conclusions:The EC burden remains substantial worldwide.Effective tobacco and obesity control measures are critical for addressing the risk-attributable burden of EC.Population growth and aging pose challenges for EC prevention and control efforts.

Colorectal cancer’s burden attributable to a diet high in processed meat in the Belt and Road Initiative countries

BACKGROUND Colorectal cancer(CRC)plays a significant role in morbidity,mortality,and economic cost in the Belt and Road Initiative(“B and R”)countries.In addition,these countries have a substantial consumption of processed meat.However,the burden and trend of CRC in relation to the consumption of a diet high in processed meat(DHPM-CRC)in these“B and R”countries remain unknown.AIM To analyze the burden and trend of DHPM-CRC in the“B and R”countries from 1990 to 2019.METHODS We used the 2019 Global Burden of Disease Study to collate information regarding the burden of DHPM-CRC.Numbers and age-standardized rates(ASRs)of deaths along with the disability-adjusted life years(DALYs)were determined among the“B and R”countries in 1990 and 2019.Using joinpoint regression analysis,the average annual percent change(AAPC)was used to analyze the temporal trends of age-standardized DALYs rate(ASDALR)from 1990 to 2019 and in the final decade(2010–2019).RESULTS We found geographical differences in the burden of DHPM-CRC among“B and R”countries,with the three highest-ranking countries being the Russian Federation,China,and Ukraine in 1990,and China,the Russian Federation,and Poland in 2019.The burden of DHPM-CRC generally increased in most member countries from 1990 to 2019(all P<0.05).The absolute number of deaths and DALYs in DHPM-CRC were 3151.15[95%uncertainty interval(UI)665.74-5696.64]and 83249.31(95%UI 15628.64-151956.31)in China in 2019.However,the number of deaths(2627.57-2528.51)and DALYs(65867.39-55378.65)for DHPM-CRC in the Russian Federation has declined.The fastest increase in ASDALR for DHPM-CRC was observed in Vietnam,Southeast Asia,with an AAPC value of 3.90%[95%confidence interval(CI):3.63%-4.16%],whereas the fastest decline was observed in Kyrgyzstan,Central Asia,with an AAPC value of-2.05%(95%CI:-2.37%to-1.73%).A substantial upward trend in ASR of mortality,years lived with disability,years of life lost,and DALYs from DHPM-CRC changes in 1990-2019 and the final decade(2010-2019)for most Maritime Silk Route members in East Asia,South Asia,Southeast Asia,North Africa,and the Middle East,as well as Central Europe,while those of the most Land Silk Route members in Central Asia and Eastern Europe have decreased markedly(all P<0.05).The ASDALR for DHPM-CRC increased more in males than in females(all P<0.05).For those aged 50-74 years,the ASDALR for DHPM-CRC in 40 members exhibited an increasing trend,except for 20 members,including 7 members in Central Asia,Maldives,and 12 high or high-middle social development index(SDI)members in other regions(all P<0.05).CONCLUSION The burden of DHPM-CRC varies substantially across“B and R”countries and threatens public health.Relevant evidence-based policies and interventions tailored to the different trends of countries in SDIs or Silk Routes should be adopted to reduce the future burden of CRC in“B and R”countries via extensive collaboration.
