Deciphering the global landscape of breast cancer in 38 OECD countries from 1990-2019: A benchmarking global analysis.

1046 Background: Breast Cancer (BC) stands as the primary contributor to disability and the second leading cause of death among countries belonging to the Organization for Economic Cooperation and Development (OECD). A comprehensive cross-country analysis of BC is crucial to monitor the growing burden. Methods: Employing the global burden of disease framework, we have calculated the incidence, prevalence, mortality, disability-adjusted life years (DALYs), and years of life lost (YLL) attributed to BC, categorized by age, gender, year, and geographical location across the 38 OECD member countries. Results: The total number of BC cases has witnessed a notable increase, rising from 5.5 million (95%UI: 5.1-6) in 1990 to 9 million (8.2-9.8) in 2019. BC-related deaths have also risen from 172,148 (164,284-176,147) in 1990 to 214,458 (195,692-226,347) in 2019, while DALYs have increased from 4.6 (4.5-4.8) in 1990 to 5.1 (4.8-5.5) in 2019. The annual percentage change (APC) in incidence has surged by 59% (44-75%) from 1990 to 2019. The highest APC in age-standardized incidence rates was observed in South Korea at 150% (99-205), while the most substantial decrease was recorded in Switzerland at 3%. Regarding death rates, Japan saw an 11% increase, Costa Rica 10%, Mexico 9%, South Korea 8%, and Turkey 4%, whereas the remaining countries witnessed a decrease from 1990 to 2019. In terms of DALY rates, Mexico and Japan experienced a 10% increase, South Korea 5%, Turkey 3%, with the rest showing a decrease from 1990 to 2019. Males bore a higher burden compared to females, with an APC in total incidence of 109% versus 58%, deaths at 73% versus 24%, and DALYs at 57% versus 10% from 1990 to 2019. The highest overall burden was observed in the 70+ age group, while the <70 and <20 age groups exhibited a decreasing trend. The total number of deaths is projected to continue increasing. Conclusions: In 2019, BC accounted for 6.64% of all cancer-related deaths and 7.9% of DALYs among women. Based on these findings, low-resource countries should consider reallocating funding to combat this burden, and public health policymakers need to prioritize surveillance and early screening efforts.

The Burden of Type 2 Diabetes Mellitus and Attributable Risk Factors in Iran, 1990-2019: Results from the Global Burden of Disease Study 2019.

This study presents estimates for type 2 diabetes mellitus (T2DM) burden and attributable risk factors in Iran from 1990-2019, using data from the 2019 Global Burden of Disease study. This study reports prevalence, incidence, death, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) of T2DM in Iran, by sex, age, and province, from 1990 to 2019. We also present the T2DM burden attributable to risk factors. Results are reported in absolute number and age-standardized rates. Overall, the burden of T2DM had increased greatly since 1990. In 2019, the T2DM incidence and prevalence cases were 291,482 (a 374% increase) and 5,035,012 (a 417% increase) respectively. Moreover, the number of death and DALYs were 14,191 (a 488% increase) and 716,457 (a 417% increase) respectively. DALYs and YLDs in women were consistently higher than men were, whereas women experienced slower increases in YLLs from 1990 to 2019. The age-standardized DALYs rate increased for all Iranian provinces during study period. High body-mass index, ambient particulate matter pollution, and low physical activity remained the three major attributable risk factors in all provinces in 2019. T2DM constitutes a major health burden in Iran. The remarkable upsurge in the T2DM burden represents an ongoing challenge, given the rapidly aging population in Iran. Thus, integrated and multi-sectoral actions that decrease exposure to risk factors and improve the prevention and early diagnosis are needed.

Trends of Potential Years of Life Lost in Pavia Province (Italy) in the Period 2015-2021: The Impact of COVID-19

The World Health Organization has declared the novel coronavirus disease, COVID-19, a pandemic from 2020 to 2023, causing more than 6.8 million deaths worldwide (updated March 2023). In record time, an anti-COVID-19 vaccine was created and large-scale mandatory vaccination was carried out. In Italy the first anti-COVID-19 vaccination started at the end of 2020. The work aimed to evaluate the impact of the COVID-19 on premature mortality in Pavia Province (Italy) with about 500,000 people in 2 different time points, during the pandemic without vaccination and with mandatory vaccination, in relation to the pre-pandemic period using Potential Years of Life Lost (PYLL). PYLL is a tool used to evaluate the effect of a specific disease on mortality for all causes. PYLLs were calculated for the 3 upper age limits (UAL): 70, 80, 90 years. The PYLL indicators showed the highest level of years of life lost in 2020, the period associated with the COVID-19 pandemic without vaccination and only other protective/preventive measures. The PYLLs decrease in 2021 to the pre-COVID-19 level may be associated with the introduction of mandatory vaccination. Keywords: PYLL, UAL, COVID-19, pandemic, Northern Italy

The invisible problem of early adolescent pregnancy in the Dominican Republic: a descriptive analysis

Study objectivesThe aim of this article is to describe the problem of pregnancy in girls under 15 years of age in the Dominican Republic in the period 2000–2021, to develop a specific indicator for this age group and describing the related factors. MethodsThis is an exploratory ecological study, based on secondary data sources, such as birth records from the National Statistics Office (NSO) and the Ministry of Public Health (MPH). We calculated the rates of fertility and pregnancy in early adolescence, as well as analyzed their main determining factors and consequences. ResultsFertility Rate in Early Adolescence (FREA) decreases from 6.27 to 1.04 per thousand in the period 2001–2021. The average FREA for 2015–2021 was 1.78. The average Estimated Rate of Pregnancy in Early Adolescence (ERPEA) for the same period was 3.39. Disability-Adjusted Life Years (DALYs) were 11,620 years. Years of Life Lost (YLL) were 9,665.9 years. The prevalence of Low Birth Weight (LBW) in the under 15-year-old age group was 14.2 %. ConclusionsPregnancy in childhood implies risks for both the mother and the child, including low birth weight. The official fertility rate is substantially underreported (2.84 vs. 1.79).The fertility rate indicator traditionally used does not accurately measure the number of pregnancies in women, particularly in specific age groups or populations where pregnancies may be interrupted by various factors. Therefore, the use of ERPEA is recommended.We emphasize the need for implementing the proposed indicator for the target group, as well as monitoring Sustainable Development Goal indicator 3.7.2.

Public Health Impacts of Ambient Particulate Matter Pollution in Libya from 1990 to 2019: An Analysis of the 2019 Global Burden of Disease (GBD) Study.

Air pollution is recognized as a critical global health risk, yet there has been no comprehensive assessment of its impact on public health in Libya until now. This study evaluates the burden of disease associated with ambient particulate matter (PM2.5) in Libya, drawing on data from the Global Burden of Disease Study 2019. By integrating satellite-based estimates, chemical transport models, and ground-level measurements, PM2.5 exposure and its effects on mortality and disability-adjusted life years (DALYs) across the different sexes and all age groups from 1990 to 2019 are estimated. Our findings reveal that the annual population-weighted mean PM2.5 concentration in Libya was 38.6 μg/m3 in 2019, marking a 3% increase since 1990. In the same year, PM2.5 was responsible for approximately 3368 deaths, accounting for 11% of all annual deaths in the country. Moreover, a total of 107,207 DALYs were attributable to PM2.5, with ischemic heart disease being the leading cause, representing 46% of these DALYs. The analysis also highlights a significant burden of years of life lost (YLLs) at 89,113 and years lived with disability (YLDs) at 18,094, due to PM2.5. Given the substantial health risks associated with air pollution, particularly from ambient particulate matter, Libyan authorities must implement effective policies aimed at reducing air pollution to enhance healthcare outcomes and preventive services.

The state of health in the European Union (EU-27) in 2019: a systematic analysis for the Global Burden of Disease study 2019

BackgroundThe European Union (EU) faces many health-related challenges. Burden of diseases information and the resulting trends over time are essential for health planning. This paper reports estimates of disease burden in the EU and individual 27 EU countries in 2019, and compares them with those in 2010.MethodsWe used the Global Burden of Disease 2019 study estimates and 95% uncertainty intervals for the whole EU and each country to evaluate age-standardised death, years of life lost (YLLs), years lived with disability (YLDs) and disability-adjusted life years (DALYs) rates for Level 2 causes, as well as life expectancy and healthy life expectancy (HALE).ResultsIn 2019, the age-standardised death and DALY rates in the EU were 465.8 deaths and 20,251.0 DALYs per 100,000 inhabitants, respectively. Between 2010 and 2019, there were significant decreases in age-standardised death and YLL rates across EU countries. However, YLD rates remained mainly unchanged. The largest decreases in age-standardised DALY rates were observed for “HIV/AIDS and sexually transmitted diseases” and “transport injuries” (each -19%). “Diabetes and kidney diseases” showed a significant increase for age-standardised DALY rates across the EU (3.5%). In addition, “mental disorders” showed an increasing age-standardised YLL rate (14.5%).ConclusionsThere was a clear trend towards improvement in the overall health status of the EU but with differences between countries. EU health policymakers need to address the burden of diseases, paying specific attention to causes such as mental disorders. There are many opportunities for mutual learning among otherwise similar countries with different patterns of disease.

Disease burden of mental disorders among children and adolescents considering both co-morbidities and suicide in Northeastern China

BackgroundFew studies have assessed the burden of mental disorders among children and adolescents considering the impact of co-morbidities and suicide on disability adjusted life years (DALYs).MethodsThis was a multicenter cross-sectional study. Our survey data in Liaoning Province (LN) were used to estimate the burden of six mental disorders, supplemented with data from other investigative studies conducted in China to assess four other disorders. DALYs were derived from the sum of years lived with a disability (YLDs) adjusted for co-morbidities, and the years of life lost (YLLs) adjusted for suicide. The changes in DALYs, YLDs, and YLLs were compared with and without adjustment for co-morbidities and suicide.ResultsThe DALYs rate of mental disorders among children and adolescents in LN decreased from 1579.6/105 to 1391.4/105, after adjusting for both co-morbidities and suicide (-11.9%). The DALYs rate for major depression, anxiety disorder, and conduct disorder (-80.8/105, -75.0/105 and -30.2/105, respectively) were the top three contributors to the DALYs reduction (-188.2/105). The YLDs decreased from 72724.8 to 62478.5 after co-morbidity adjustment (-17.8%), mainly due to the reduction by major depression (-35.3%) and attention deficit/hyperactivity disorder [ADHD] (-34.2%). The YLLs increased from 130 to 1697.8 after adjusting for suicides (+ 56.9% of all suicide YLLs), mainly due to the contribution of major depression (+ 32.4%) and anxiety disorder (+ 10.4%). Compared to GBD 2010, the estimated DALY rate for mental disorders in LN was to be about 80%, with the proportion of DALYs and DALY rates explained by major depressive disorder accounted for only approximately one-third (14.6% vs. 41.9% and 202.6 vs. 759.9, respectively). But the proportion and absolute level of DALY rates explained by anxiety disorders were approximately 2-fold higher (39.7% vs. 19.6% and 552.2 vs. 323.3, respectively).ConclusionsThe DALYs of mental disorders among Chinese children and adolescents were approximately 80% of the global level, with anxiety disorders imposing about 2 times the global level. Co-morbidity and suicide must be adjusted when calculating DALYs.

Spatial disparities in the mortality burden of the covid-19 pandemic across 569 European regions (2020-2021)

Since its emergence in December 2019, the COVID-19 pandemic has resulted in a significant increase in deaths worldwide. This article presents a detailed analysis of the mortality burden of the COVID-19 pandemic across 569 regions in 25 European countries. We produce age and sex-specific excess mortality and present our results using Age-Standardised Years of Life Lost in 2020 and 2021, as well as the cumulative impact over the two pandemic years. Employing a forecasting approach based on CP-splines that considers regional diversity and provides confidence intervals, we find notable losses in 362 regions in 2020 (440 regions in 2021). Conversely, only seven regions experienced gains in 2020 (four regions in 2021). We also estimate that eight regions suffered losses exceeding 20 years of life per 1000 population in 2020, whereas this number increased to 75 regions in 2021. The contiguity of the regions investigated in our study also reveals the changing geographical patterns of the pandemic. While the highest excess mortality values were concentrated in the early COVID-19 outbreak areas during the initial pandemic year, a clear East-West gradient appeared in 2021, with regions of Slovakia, Hungary, and Latvia experiencing the highest losses. This research underscores the importance of regional analyses for a nuanced comprehension of the pandemic’s impact.

Liver cancer in China: the analysis of mortality and burden of disease trends from 2008 to 2021

BackgroundLiver cancer is one of the most common cancers in China. To understand the basic death situation and disease burden change trend, we analyze the death information of liver cancer among Chinese residents from 2008 to 2021.MethodsData was collected from the Cause-of-Death Surveillance dataset of the National Cause-of-Death Surveillance System from 2008 to 2021. Excel 2016 was used for data entry and to calculate the Crude Mortality Rate (CMR), Age-Standardized Mortality Rate (ASMR), Potential Years of Life Lost (PYLL), and Potential Years of Life Lost Rate (PYLLR). SPSS 25.0 was used to statistically analyze CMR, ASMR, PYLL, and other indicators. Annual percent change (APC) and average APC(AAPC) was used for trend analysis and tested by t tests. Joinpoint 4.9.1.0 was used to calculate APC and AAPC. Age-Period-Cohort model was used to assess the effects of age, period, and birth cohort on liver cancer mortality.ResultsFrom 2008 to 2021, 491,701 liver cancer deaths were reported in the National Disease Surveillance Points System. The ASMR of liver cancer in Chinese residents decreased from 27.58/100,000 in 2008 to 17.95/100,000 in 2021 at an average annual rate of 3.40% (t = -5.10, P < 0.001). The mortality rate was higher in males than in females (all P < 0.001) and higher in rural areas than in urban areas (all P < 0.001). The mortality rate of liver cancer varied significantly among eastern, central, and western China (all P < 0.001). The PYLLR of liver cancer in Chinese residents decreased from 2.89‰ in 2008 to 2.06‰ in 2021 at an average annual rate of 2.40% (t = -5.10, P < 0.001). Males had a lower PYLLR than females, decreasing at average annual rates of 2.20% (t = -5.40, P < 0.001) and 2.90% (t = -8.40, P < 0.001), respectively. Urban areas had a lower PYLLR than rural areas, decreasing at average annual rate of 3.30% (t = -4.00, P < 0.001) and 2.50% (t = -11.60, P < 0.001), respectively. Eastern, central, and western China decreased at average annual rates of 3.40%, 2.30%, and 2.10%, respectively (t = -7.80, -3.60, -7.10, P < 0.001 for all). The risk of China liver cancer mortality increased with age, decreased with birth cohort.ConclusionsThe mortality and disease burdens of liver cancer in China decreased yearly and were higher in males and in people living in rural areas, with significant differences among those living in eastern, central, and western China.

Premature Mortality Excess Rates Before and During the COVID-19 Pandemic: A Comparative Analysis Conducted in Bihor County, Romania.

Estimating the excess of premature deaths (before the age of 75 years) and Potential Years of Life Lost allows ranking causes of death as an expression of the burden of disease in a population.We statistically analysedthe impact of the coronavirus disease 2019 (COVID-19) pandemic on excess premature mortality in the total population and specifically, by sexes, compared to the pre-pandemic period, through Potential Years of Life Lost. In this retrospective descriptive observational study, we counted excess of premature mortality in the years 2020, 2021, and 2022 by cause of death (cardiovascular diseases, cancer, digestive diseases, injury, COVID-19, and other causes) and by sexes compared to the period average from 2017-2019, based on the deaths registered in Bihor County (48,948 people). Premature deaths due to COVID-19 (1,745 people ofboth sexes) contributed 71.3% to excess mortality, the population being similar for both sexes (71.4% in men and 71.2% in women). The Potential Years of Life Lost/death due to COVID-19 was 11.84 years for both sexes (11.76 years in men and 12.02 years in women). Potential Years of Life Lost/all-cause heath was lower during the pandemic (13.42 years for both sexes, 14.06 years for men and 12.32 years for women) compared to the pre-pandemic period (14.6 years for both sexes, 15.1 years for men and 13.5 years for women). The excess of premature mortality and decreased Potential Years of Life Lost/death during the pandemic, shows an increase in the proportion of deaths at ages closer to the established limit for premature mortality (75 years) compared to the pre-pandemic period.

Analysis of the global burden of cervical cancer in young women aged 15-44 years old.

Understanding the burden of cervical cancer (CC) in young women aged 15-44 years old are essential for formulating effective preventive strategies. Utilizing the Global Burden of Disease 2019 Study, we estimated incidence, disability-adjusted life-years (DALYs), years of life lost (YLLs) and years lived with disability (YLDs) due to CC among young women from 1990 to 2019. Additionally, we evaluated the temporal trends using estimated annual percentage changes (EAPCs) during this period. We conducted a decomposition analysis to assess the absolute contributions of three components: population growth, population age structure and epidemiologic changes. Globally, there were 187 609.22 incident cases of CC worldwide, resulting in 2621 917.39 DALYs in 2019. From1990 to 2019, the age-standardized rates were decline, only the age-standardized YLDs rate (EAPC = 0.02; 95% CI: -0.02 to 0.05) showed a stable trend. The largest increase in age-standardized incidence rate (ASIR) and age-standardized YLDs rate observed in the high-middle social demographic index (SDI) quintiles. Population growth and age structure changes were associated with substantial changes in cases of CC, especially in South Asia and East Asia. Globally, the burden of CC in young women continues to increase, as measured by the absolute number. As populations are growing and age structure changes were associated with substantial changes in cases of CC, governments will face increasing demand for treatment, and support services for CC, especially in South Asia and East Asia.

Current immunotherapeutic approaches to diffuse intrinsic pontine glioma.

Diffuse intrinsic pontine glioma (DIPG) is an aggressive brain tumour that occurs in the pons of the brainstem and accounts for over 80% of all brainstem gliomas. The median age at diagnosis is 6-7years old, with less than 10% overall survival 2years after diagnosis and less than 1% after 5years. DIPGs are surgically inaccessible, and radiation therapy provides only transient benefit, with death ensuing from relentless local tumour infiltration. DIPGs are now the leading cause of brain tumour deaths in children, with a societal cancer burden in years of life lost (YLL) of more than 67 per individual, versus approximately 14 and 16 YLL for lung and breast cancer respectively. More than 95 clinical drug trials have been conducted on children with DIPGs, and all have failed to improve survival. No single or combination chemotherapeutic strategy has been successful to date because of our inability to identify targeted drugs for this disease and to deliver these drugs across an intact blood-brain barrier (BBB). Accordingly, there has been an increased focus on immunotherapy research in DIPG, with explorations into treatments such as chimeric antigen receptor T (CAR-T) cells, immune checkpoint blockades, cancer vaccines, and autologous cell transfer therapy. Here, we review the most recent advances in identifying genetic factors influencing the development of immunotherapy for DIPG. Additionally, we explore emerging technologies such as Magnetic Resonance-guided Focused Ultrasound (MRgFUS) in potential combinatorial approaches to treat DIPG.

Premature mortality for patients after completely resected early adenocarcinoma of the esophagus or stomach.

To establish the life expectancy burden of esophago-gastric cancer by analyzing years of life lost (YLL) for a Western patient population after treatment of early esophageal (EAC) or early gastric (GAC) adenocarcinoma. For patients with early EAC or GAC, the short-term prognosis after surgical resection is very good. Little data is available regarding long-term prognosis when compared to the general population. Two hundred and fourteen patients with pT1 EAC (n = 112) or GAC (n = 102) were included in the study. Patients with EAC underwent transthoracic en-bloc esophagectomy; those with GAC had total or subtotal gastrectomy with D2-lymphadenectomy. Surviving patients had a median follow-up of approximately 14 years. YLL was calculated using average life expectancy data from Germany. Patients with EAC were younger (median age 61 years) than those with GAC (66 years) (p = 0.031). The male:female ratio was 10:1 for EAC and 3:2 for GAC (p < 0.001). Multivariate survival analysis showed the age of the patients ≥60 years and the existence of lymph node metastasis was associated with poor prognosis. The median YLL for all patients who died over follow-up was 8.0 years. For patients under 60 years, it was approximately 20 years, and for older patients, approximately 5 years (p < 0.001) without difference in tumor stage between these age cohorts. YLL did not differ for GAC vs. EAC. After surgical resection, the prognostic burden as measured by YLL is relevant for all patients with early esophageal and gastric adenocarcinomas and especially for younger patients. Reasons for YLL need further studies.

Years of Life Lost Due to Premature Mortality in Northern Iran: A Cross-sectional Study

Background: Years of life lost (YLL) is commonly used to determine the social and economic burden of loss due to premature mortality. The present study estimated YLL based on general mortality groups in Golestan Province, Iran, in 2018. Methods: In this cross-sectional study, by referring to the province death registration system information and using standard expected years of life lost (SEYLL) of the World Health Organization (WHO), YLL was calculated due to premature mortality based on general mortality groups in ICD-10 (international classification of diseases 10th revision). Results: The total number of deaths in Golestan Province was 8543 in 2018. The overall YLL due to premature mortality was 129838 years, of which 57.4% occurred among men. The major causes of YLL due to premature mortality (YLL%) were diseases of the circulatory system (I00-I99) (32.3%), external causes (V01-Y89) (17.3%), certain conditions originating in the perinatal period (P00-P96) (14.5%), and cancers (C00-D48) (13.9%). After diseases of the circulatory system, the most common cause of YLL due to premature mortality is external causes (22.9%) among men and cancers (16.2%) among women. In general, the highest YLL rate occurred due to circulatory system diseases (22.5 per 1000 people). Conclusion: According to the results of our study, most years of life lost in both sexes are related to diseases of the circulatory system, followed by external causes of morbidity and mortality. Therefore, it is important to pay attention to the diseases of the circulatory system and its causes, as well as external causes of morbidity and mortality.

Infective Endocarditis in North Africa and the Middle East, 1990‒2019: Updates from the Global Burden of Disease Study 2019.

Infective endocarditis (IE), a severe and economically impactful condition, lacks substantial epidemiological data in the North Africa and Middle East (NAME) region. This study focused on analyzing the trends and burden of IE in NAME from 1990 to 2019, taking into account factors like age, gender, and socio-demographic index (SDI). The Global Burden of Disease data from 1990 to 2019 was retrieved from the Institute for Health Metrics and Evaluation (IHME) website. Between 1990 and 2019, the age-standardized rates (ASR) for IE incidence increased by 59%, and prevalence and years lived with disability (YLDs) rose by 12% and 9%, respectively, while the ASRs for deaths, disability-adjusted life years (DALYs), and years of life lost (YLLs) saw reductions of 22%, 34%, and 34% in the NAME region. Death rates among children under five declined by 72%. Gender and the SDI did not significantly influence these changes. Saudi Arabia witnessed the most significant increase in ASR of IE incidence since 1990, while Turkey had the highest rates in 2019. The year 2019 also saw the highest death rate among those aged 70 and over, with over 91000 DALYs from IE. DALYs decreased by 71.5% for children under five from 1990 to 2019 but remained stable for individuals in their seventies. Jordan showed the most notable decrease in ASRs for deaths, DALYs, and YLLs among children under five. This study highlights the changing epidemiology of IE in the NAME region, recommending the establishment of multidisciplinary IE registries, antibiotic prophylaxis guidelines for healthcare-associated IE, and strategies to control antimicrobial resistance as key mitigation measures.

The Age- And Sex- Specific Burden of Transport Injuries in India Over a Decade From 2010-2019: A Systematic Analysis from Global Burden of Diseases 2019

Background: In India, transport injuries persist as leading preventable causes of mortality and morbidity for a large number of people, including children, young adults and elderly people. The objective is to estimate the transport injury-related mortality and morbidity in India over the past decade from 2010-2019. Methodology: By using the Global Burden of Diseases, Injuries, and Risk Factors 2019 Study (GBD), we analysed mortality, Disability-Adjusted Life-Years (DALYs), Years Lived in Disability (YLDs), Years of Life Lost (YLL), prevalence rate (per 100K) attributed to transport injuries for all ages, in India. Burden is reported in absolute numbers and percentage changes over a decade period from 2010 to 2019; stratified by sex ratio, and age groups, with 95% confidence intervals (CIs). Results: Transport injuries had accounted for 235,444 deaths (2.51%) in 2019; and 231,177 deaths (2.68%) in 2010. Transport injuries are the leading cause of death among people aged 15-49 years with more than 50% of burden in India. Death-rate due to transport had declined from 18.77 to 16.93 per 100,000 populations over a decade (2010-2019). Conclusions: Over a decade, progress made in the burden of transport injuries was limited and the burden had started to rise after achieving some success till 2016. India needs to sustain and improve the progress made in order to achieve UN goals for 2030.

Global trends and differences in the burden of alcohol use disorders attributable to childhood sexual abuse by sex, age, and socio-demographic index: Findings from the Global Burden of Disease Study 2019

BackgroundChildhood sexual abuse (CSA) is a severe global problem associated with alcohol use disorder (AUD). Previous studies have confirmed this relationship; however, there is a lack of research on the disease burden of AUD attributable to CSA. ObjectiveTo analyze global spatiotemporal trends and differences in the disease burden of AUD attributable to CSA and its relationship with age, sex, and the sociodemographic index (SDI). Participants and settingData from the Global Burden of Disease 2019 Public Database. MethodsSummary exposure value (SEV) was used to evaluate CSA. Disability-adjusted life year (DALY), years lived with disability (YLD), years of life lost (YLL), and their annual rates of change were used to evaluate disease burden. Cluster analysis based on Ward's method was used to examine the global burden associated with age, sex, and SDI. A 95 % uncertainty intervals (UI), excluding 0, was considered statistically significant. ResultsIn 2019, 1.63 million (95 % UI 0.23–3.90 million) DALYs of AUD were caused by CSA and the age-standardized rates (ASRs) of DALY was 19.77 (95 % UI 2.78–47.46) globally. Annual rates of change in DALY of people over 65 years of age increased from 1990 to 2019 in all regions except the High-middle SDI regions. The ASRs of DALY of females in High SDI regions, were always at a much higher level than other SDI regions, and showed an upward trend from 1990 to 2019 (DALY 1990: 20.38 [95 % UI 2.87–47.77], 2019: 23.61 [95 % UI 3.55–54.94]). ConclusionsSubstantial geographical differences were observed in the burden of AUD attributable to CSA. The level of CSA exposure was inconsistent with the related burden of AUD in different regions according to the sociodemographic index. The burden of disease increased in the elderly population and in females in high sociodemographic index regions.

Gender-age peculiarities of disability-adjusted life years (DALYs) in tuberculosis in a high-density region: a retrospective cohort study

Background. Infections associated with socially significant diseases considerably contribute to a decrease in the quality of public health. Tuberculosis, though declining in Russia, is still recognized as a pressing public health problem. Meanwhile, an assessment of the burden of tuberculosis on society, using such comprehensive methods as measuring disability-adjusted life years, is yet to be investigated in Russia. Objective. To estimate the tuberculosis burden by calculating the index of disability adjusted life years in a high-density region.Methods. The retrospective cohort study involved data on newly-diagnosed and died of tuberculosis cases that corresponded to the annual reporting form of federal statistical surveillance No. 8 “Information on active tuberculosis cases” for the Republic of North Ossetia-Alania; information on patients who died of tuberculosis or tuberculosis combined with infection caused by human immunodeficiency virus, was obtained from the Department of Civil Status Records of the Republic of North Ossetia-Alania and verified with data from the Federal State Statistics Service; data on tuberculosis-associated disability was received from Main Bureau of Medical and Social Expertise in the Republic of North Ossetia-Alania of the Ministry of Labor and Social Protection of the Russian Federation for 2018 and 2022. Following the analytic dataset, 691 people with newly-diagnosed tuberculosis, who received TB-associated disability and died from TB in 2018 (318 people) and 2022 (373 people) were identified. The study involved calculation of gender and age standardized TB morbidity and mortality rates as well as DALY index with its components: Years of Life Lost due to tuberculosis and Years Lost due to Disability. The study involved comparing data between 2018 and 2022 and gender/age-specific indicators within the same year. Mathematical data processing was performed using Microsoft Excel 2017 (Microsoft Corporation, USA) and SPSS 26.0 (SPSS Inc., USA). Differences between the compared indicators were evaluated by Chi-square criterion with variations, the initial data were grouped in a contingency table, the significance of differences was expressed by p-value.Results. The burden of tuberculosis in the Republic of North Ossetia-Alania refers predominantly to the male population: with a gender difference in the decrease in the disability-adjusted life years in 2018 and 2022 by 4.4 and 9.0 times (p &lt; 0.05), respectively; 2.8 times among males, 5.5 times among females (p &lt; 0.05). The burden of tuberculosis is mainly associated with premature mortality due to tuberculosis among males aged 35–54 years and among females aged 35–44 years with a pronounced decrease in Years of Life Lost. Years of Life Lost among males aged 20–34 in 2022 appears two times higher than the cohort average. The increase in Years of Life Lost among males aged 60–64 accounted for 1.7 times, in Years Lost Due to Disability — 11.2 times (p &lt; 0.05). Years Lost Due to Disability among females aged 20–44 years appeared to be the highest, exceeding the cohort average by more than two times in 2018.Conclusion. The burden of tuberculosis is predominantly due to tuberculosis-related premature mortality among the male population. According to the disturbing conclusion, Years of Life Lost among young males aged 20–34 years and tuberculosis-related premature mortality shift towards the male population of pre-retirement age (60–64 years) with an increase in Years Lost Due to Disability among them. Notably, the study reveals high rates of Years Lost Due to Disability among females aged 20–44. The results obtained should be taken into account when developing regional tuberculosis programs with their targeted use in “vulnerable” age and gender groups of the population.

Mortality and years of life lost related to adverse drug events in Brazil.

To assess regional and national mortality and years of life lost (YLL) related to adverse drug events in Brazil. This is an ecological study in which death records from 2009 to 2018 from the Mortality Information System were analyzed. Codes from the International Classification of Diseases 10th revision (ICD-10) that indicated drugs as the cause of death were identified. The number of deaths and the YLL due to adverse drug events were obtained. Crude, age- and gender-specific, and age-adjusted mortality rates and YLL rates per 100,000 inhabitants were formed by year, age group, gender, and Brazilian Federative Unit. Rate ratios were calculated by comparing rates from 2009 to 2018. A joinpoint regression model was applied for temporal analysis. For the selected ICD-10 codes, a total of 95,231 deaths and 2,843,413 YLL were recorded. Mortality rates from adverse drug events increased by a mean of 2.5% per year, and YLL rates increased by 3.7%. Increases in rates were observed in almost all age groups for both genders. Variations in rates were found between Federative Units, with the highest age-adjusted mortality and YLL rates occurring in the Distrito Federal. The numbers and rates of deaths and YLL increased during the study period, and variations in rates of deaths and YLL were observed between Brazilian Federative Units. Information on multiple causes of death from death certificates can be useful for quantifying adverse drug events and analyzing them geographically, by age and by gender.
