Quality-adjusted life years and surgical waiting list:Systematic review of the literature

BACKGROUND The quality-adjusted life year(QALY)is a metric that is increasingly used today in the field of health economics to evaluate the value of different medical treatments and procedures.Surgical waiting lists(SWLs)represent a pressing problem in public healthcare.The QALY measure has rarely been used in the context of surgery.It would be interesting to know how many QALYs are lost by patients on SWLs.AIM To investigate the relationship between QALYs and SWLs in a systematic review of the scientific literature.METHODS The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement.An unlimited search was carried out in PubMed,updated on January 19,2024.Data on the following variables were investigated and analyzed:Specialty,country of study,procedure under study,scale used to measure QALYs,the use of a theoretical or real-life model,objectives of the study and items measured,the economic value assigned to the QALY in the country in question,and the results and conclusions published.RESULTS Forty-eight articles were selected for the study.No data were found regarding QALYs lost on SWLs.The specialties in which QALYs were studied the most in relation to the waiting list were urology and general surgery,with 15 articles each.The country in which the most studies of QALYs were carried out was the United States(n=21),followed by the United Kingdom(n=9)and Canada(n=7).The most studied procedure was organ transplantation(n=39),including 15 kidney,14 liver,5 heart,4 lung,and 1 intestinal.Arthroplasty(n=4),cataract surgery(n=2),bariatric surgery(n=1),mosaicplasty(n=1),and septoplasty(n=1)completed the surgical interventions included.Thirty-nine of the models used were theoretical(the most frequently applied being the Markov model,n=34),and nine were real-life.The survey used to measure quality of life in 11 articles was the European Quality of Life-5 dimensions,but in 32 articles the survey was not specified.The willingness-to-pay per QALY gained ranged from$100000 in the United States to€20000 in Spain.CONCLUSION The relationship between QALYs and SWLs has only rarely been studied in the literature.The rate of QALYs lost on SWLs has not been determined.Future research is warranted to address this issue.

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.

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.

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.

Racial disparity in years of potential life lost to induced abortions

The magnitude of the overall prevalence and racial disparity in induced abortion suggests that it is a major influence on the demographic and socioeconomic composition of the population of the United States (US). However, the years of potential lives averted by induced abortion have not been systematically studied. We applied race-specific intra-uterine death estimates to the induced abortions occurring to non-Hispanic (NH) white and non-Hispanic (NH) black women in the US state of North Carolina in 2008. The resultant estimate of births averted by induced abortion was used to project years of potential life lost. All-cause detailed mortality data were used to compare induced abortion with other contributing causes of years of potential life lost before age 75 (YPLL 75). For NH whites, induced abortions in 2008 contributed 59% of total YPLL 75, and 1.5 times the total YPLL 75 from all other causes combined. For NH blacks, induced abortions in 2008 contributed 76% of total YPLL 75 and 3.2 times the total YPLL 75 from all other causes combined. Induced abortion is the overwhelmingly predominant contributing cause of preventable potential lives lost in the North Carolina population, and NH blacks are disproportionately affected.

Maternal Death and Potential Years of Life Lost(PYLL)in Santa Catarina,Brazil,in 2000 and 2014

Introduction: Indicators of maternal health are often used to evaluate the social development and overall health of a population, as well as the accessibility of health services. Among these indicators, the Potential Years of Life Lost, which is associated with maternal deaths, is useful for the definition of priorities, monitoring, evaluation, and intervention, identifying the highest risk groups. Objective: To analyze the Potential Years of Life Lost by maternal death in Santa Catarina in 2000 and 2014. Method: An Ecological study with exploratory spatial analysis was conducted with data obtained from the Information System on Mortality and Live Births. Results: In the Information System, 35 maternal deaths in the year 2000 were identified and 24 in 2014. The total estimated years of life lost were 845 years in 2000 and 780 years in 2014, dominated by direct obstetric causes. In 2000, women who died lost, on average, 39.8 years of life;and 41.5 years in 2014. Conclusion: The spatial pattern observed in 2000 highlights areas of high risk in different regions of Santa Catarina. The greatest loss of years occurred in younger women, confirming the need to prevent and control maternal mortality and review strategies for compliance with public policies in the State.

I Do Biotech Dental Implants: Prospective Multicentric Study after 5 Years of Functional Loading

Introduction: I Do Biotech’s implants were developed starting in 2014. Since then, they obtained GMP and KFDA licenses for distribution in 2015. The main objective of this paper is to determine the survival rate of I Do Biotech implants five years after the first surgery. Material and Methods: 1000 implants were used on 480 prostheses across 10 clinics on 320 healthy, non-smoker and non-diabetic patients, chosen at random, of which 160 are male and 160 female, all in the age range of 30 to 50 years old. The failure rate was studied related to the patient’s gender, the length and diameter of the implant, anatomical location, the percentage of peri-implantitis, prosthodontic failures and the patient’s quality of life. Discussion: The results obtained are similar to those of Van Steenberghe D. Dieter-Busenlechner, E. Serrano Catauria and far superior to those of Sáenz Guzmán. Failure rates vary greatly from study to study due to the heterogeneity of the samples in the other research papers. Conclusion: The overall implant failure rate at 5 years is 1.7%. The factors affecting significantly the survival rate are: the implant diameter, its length and the anatomic area. Failure ratios increase significantly when the diameter or the length of the implant decreases, and when they are placed in the posterior maxilla (up to 4.3%). The rate of peri-implantitis is 5.1%. The prosthodontic failure rate is 2.91%. The improvement in quality of life and satisfaction increases with the years.

BRAIN TUMORS OF THE FIRST YEAR OF LIFE:CLINICAL AND SURGICAL MANAGEMENT

Brain tumors incidence in pediatric age hasbeen estimated between 1.3 to 5% with a relativeincidence of 1.4 to 11% during the first year oflife; the improvement in instrumental deviceshas lead to a relative increase in precocious diag-nosis. The choice to study brain tumors of the firstyear of life as a separate topic from pediatric ageones depends on the observation that these le-sions have peculiar clinical, topographic and tis-sular characteristics. The survival rate of thesepatients is very poor if compared with that found

1990-2019年中国成年人归因于糖尿病的心血管疾病负担研究

背景在全球老龄化不断深化的背景下,慢性病患者不断增加,多病共存现象愈加严重。在普遍认知中,心血管疾病与2型糖尿病大多属于老年病,但随着居民生活节奏与饮食等行为方式的改变,很多疾病呈现年轻化趋势。现也有研究表明,与一般人群相比,年轻时患糖尿病的患者的心血管疾病风险及死亡率会相对增加。目的探究1990—2019年中国成年人归因于糖尿病的心血管疾病负担情况,为共病预防提供依据。方法基于2019年全球疾病负担研究(GBD)数据,主要采用死亡率、伤残调整寿命年(DALY)率和计算获取的年估计变化百分比(EAPC)等指标评估我国心血管疾病(包括缺血性心脏病、脑卒中和外周动脉疾病3类)归因于糖尿病的疾病负担情况,并对年龄段(25~49岁、50~69岁、≥70岁)及性别进行分层分析,最后对疾病负担的时间趋势进行分析。结果中国25岁及以上人群归因于糖尿病的心血管疾病死亡数从1990年的29.805万例上升到2019年的70.034万例。男性归因于糖尿病的心血管疾病标化死亡率较1990年升高,而女性标化死亡率有所降低,且男性标化死亡率始终高于女性。2019年归因于糖尿病的心血管疾病DALY为1358.585万人年,按年龄划分的死亡率和DALY率随年龄增长而增加。女性标化DALY率下降趋势较男性明显(女性:EAPC=-0.32%,95%CI=-0.49%~-0.11%;男性:EAPC=-0.01%,95%CI=-0.26%~0.29%)。2019年归因于糖尿病的缺血性心脏病、外周动脉疾病患者3个年龄段的死亡率和DALY率较1990年大部分上升,而2019年归因于糖尿病的脑卒中患者3个年龄段的死亡率较1990年下降。1990—2019年心血管疾病中3类心血管疾病归因于糖尿病的标化DALY率占比呈波动性变化,但在2019年归因于糖尿病的3类心血管疾病标化DALY率占比均高于1990年。结论1990—2019年我国成年人归因于糖尿病的心血管疾病的死亡率和DALY率总体呈现上升趋势,人群糖尿病及心血管疾病共病风险较大,应注重在糖尿病患者中筛查心血管疾病或患心血管疾病风险高的个体,重点关注男性、高龄人群以及不良生活习惯较多的年轻人,对其进行早期的健康干预,减少共病疾病负担。

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.

目的了解1990-2019年中国慢性阻塞性肺疾病发病、患病、死亡情况及疾病负担情况,预测2020-2030年中国慢性阻塞性肺疾病发病情况,为评估和制定慢性阻塞性肺疾病相关预防治疗政策和措施提供数据支持。方法利用2019年全球疾病负担研究数据库(Global burden of disease study,GBD),研究分析1990-2019年中国慢性阻塞性肺疾病的发病、患病、死亡、伤残调整寿命年(DALY)、早死寿命损失年(YLL)、伤残寿命损失年(YLD)等情况。采用贝叶斯-时期-队列分析(BAPC)方法,预测2020-2030年中国慢性阻塞性肺疾病发病率。结果相对于1990年,2019年中国慢性阻塞性肺疾病粗患病率增长35.44%,标化患病率减少27.16%,粗发病率增长38.31%,标化发病率减少28.52%,粗死亡率减少30.59%,标化死亡率减少70.08%。1990-2019年中国人群因慢性阻塞性肺疾病导致的YLL率由3281.48/10万降至862.37/10万,YLD率由330.33/10万降至240.40/10万,DALY率由3611.81/10万降至1102.77/10万。2019年男性慢性阻塞性肺疾病DALY率相比于1990年降低66.56%,女性DALY率相比于1990年降低71.87%。2020-2030年中国慢性阻塞性肺疾病标化发病率预计呈下降趋势,2030年男性标化发病率预计比2020年降低31.97%,女性标化发病率预计比2020年降低27.69%。结论1990-2019年,慢性阻塞性肺疾病对中国人口造成的疾病负担总体呈下降趋势。但从患病情况和死亡情况来看,发病及死亡人数较多,中国慢性阻塞性肺疾病的疾病负担仍处于较高水平。同时预测结果显示,未来10年中国慢性阻塞性肺疾病标化发病率在下降,但是仍处于较高水平,因此进行早筛查、早预防和早治疗,及广泛开展慢阻肺相关知识普及,对于做好COPD疾病管理具有重要意义。

2014—2023年镇江市居民恶性肿瘤疾病负担趋势

目的了解镇江市居民恶性肿瘤死亡率和疾病负担及变化趋势。方法利用2014—2023年镇江市死因监测数据,计算恶性肿瘤粗死亡率、标化死亡率、早死寿命损失年(YLLs)、YLLs率,采用平均年度变化百分比(AAPC)分析变化趋势。结果2014—2023年,镇江市因恶性肿瘤死亡73922例,年均粗死亡率为318.44/10万,标化死亡率为262.33/10万。粗死亡率和标化死亡率男性均高于女性(χ^(2)值分别为6087.30、199262.00,P值均<0.05)。总人群、男性恶性肿瘤粗死亡率呈上升趋势(AAPC分别为0.91%、1.19%),全人群、男性、女性恶性肿瘤YLLs率呈下降趋势(AAPC分别为-1.19%、-1.01%、-1.43%,P值均<0.05)。2023年死因顺位前5位恶性肿瘤依次为肺癌(占20.35%)、胃癌(占20.19%)、食道癌(占13.19%)、结直肠癌(占9.73%)、肝癌(占9.47%),合计占全部恶性肿瘤死亡的72.93%。相比2014年,肺癌全人群和男、女性YLLs率变化趋势无统计学意义(P值均>0.05),胃癌、食道癌、肝癌全人群、男、女性YLLs率均呈下降趋势(P值均<0.05),结直肠癌全人群、男性YLLs率均呈下降趋势(P值均<0.05)。结论镇江市恶性肿瘤标化死亡率和标化YLLs率均呈下降趋势,但依然处于较高水平,应重点关注肺癌和胃癌等消化系统肿瘤的综合防控。
