Inequalities in severe COVID-19 outcomes in Wales, UK

ObjectiveResearch evidence shows that COVID-19 has disproportionately affected people from more deprived backgrounds. In Wales (UK), there is strong evidence of a socioeconomic gradient in total hospitalisations, critical care admissions and deaths. This study focussed on a cohort of the Welsh population using anonymised individual-level linked population-scale data in the SAIL Databank. ApproachThis analysis examines the impact of confounding/mediating factors on severe health outcomes. We used logistic regression, considering the Welsh Index of Multiple Deprivation (WIMD) 2019 as a predictor, to investigate how the coefficient for WIMD is changed when other variables (such as comorbidities, smoking status, Body Mass Index) are added, aiming to understand whether inequalities are mediated by observed characteristics or related to other unobserved factors. ResultsInitial findings show that age-standardised rates of hospital admissions, Intensive Care Unit (ICU) admissions and deaths were roughly twice as high in the most deprived vs least deprived WIMD quintile in Wales. We estimated Years of Life Lost per 1,000 due to COVID-19 as 28.9, with variation between WIMD quintiles of 38.4 for the most deprived and 22.2 for the least deprived. The project also produced regression formulas to evaluate the contribution of the different confounding factors. ConclusionThis study built on existing research findings and further explored the potential reasons for known socioeconomic inequalities in relation to COVID-19 outcomes. Insights from this study have broadened the knowledge around the impact of mediating factors and may contribute to future pandemic preparedness and the formation of future policies.

Spatial-temporal distribution of neglected tropical diseases burdens in China from 2005 to 2020

BackgroundOut of the 21 neglected tropical diseases (NTDs) listed by the World Health Organization, 15 affect the People’s Republic of China. Despite significant achievements in controlling NTDs, comprehensive assessments of the disease burden based on actual case data and detailed information on spatial and temporal dynamics are still lacking. This study aims to assess the disease burden and spatial–temporal distribution of NTDs in China from 2005 to 2020, to provide a reference for the formulation of national health agendas in line with the global health agenda, and guide resource allocation.MethodsThe number of cases and deaths of major NTDs in China from 2005 to 2020 were downloaded from the China Public Health Science Data Center (https://www.phsciencedata.cn/Share/index.jsp) of the Chinese Center for Disease Control and Prevention and relevant literatures. Simplified formulas for disability-adjusted life years (DALYs) helped estimate the years of life lost (YLLs), years lived with disability (YLDs), and total DALYs. Spatial autocorrelation analysis of the average NTDs burden data for the years 2005 to 2020 was evaluated using Moran's I statistic.ResultsChina's overall NTDs burden decreased significantly, from 245,444.53 DALYs in 2005 to 18,984.34 DALYs in 2020, marking a reduction of 92.27%. In 2005, the DALYs caused by schistosomiasis and rabies represent a substantial proportion of the total disease burden, accounting for 65.37% and 34.43% respectively. In 2015, Hunan and Sichuan provinces had the highest diversity of NTDs, with 9 and 8 number of different NTDs reported respectively. And the highest disease burden was observed in Sichuan (242,683.46 DALYs), Xizang Zizhiqu (178,318.99 DALYs) and Guangdong (154,228.31 DALYs). The “high-high” clustering areas of NTDs were mainly in China's central and southern regions, as identified by spatial autocorrelation analysis.ConclusionsChina has made unremitting efforts in the prevention and control of NTDs, and the disease burden of major NTDs in China has decreased significantly. Using the One Health concept to guide disease prevention and control in the field to effectively save medical resources and achieve precise intervention.Graphical abstract

Trend of gastrointestinal and liver diseases in China: Results of the Global Burden of Disease Study, 2019.

China is one of the countries with the largest burden of gastrointestinal and liver diseases (GILD) in the world. The GILD constitutes various causes of mortality and disability. The study aimed to investigate the trend of GILD in China using the Global Burden of Diseases Study 2019 (GBD 2019) data resources from 1990 to 2019. The data on the age-standardized mortality rates (ASMR) and disability-adjusted life years (DALYs) for GILD in China from 1990 to 2019 were collected from the GBD 2019 data resources. Furthermore, the ranking of the main causes of deaths and DALYs, as well as the trends of ASMR, DALYs, years of life lost (YLLs), and years of life lost due to disability (YLDs) per 1,000,000 in GILD were reported. The ASMR and DALYs for stomach cancer, liver cancer, and esophageal cancer, which ranked top three among the GILDs from 1990 to 2019, were gradually decreasing. Significant decreases in the ASMR and DALYs were found in diarrheal diseases and acute hepatitis (A, E, and C). However, noteworthy increases were found in those of colon and rectum cancer (CRC) and pancreatic cancer. Trend of DALYs, mortality, and YLLs rates for most of GILD were decreasing from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trend. The DALYs, mortality and YLLs of most GILD diseases showed decreasing trends from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trends. The result of the GBD 2019 showed that the rates of most GILDs decreased in China; however, gastrointestinal and liver cancer, such as stomach cancer still held the top ranking. Furthermore, the shift from infectious diseases to non-communicable causes among GILD burden is occurring and is likely to continue with many public health strategies implications.

The burden of liver cancer in Mongolia from 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019.

Liver cancer remains the leading cause of death and public health threat among the Mongolian population. So far, there has been no in-depth analysis to describe the burden of common attributable factors to liver cancer in Mongolia. Therefore, we aimed to explore the most prevalent causes of liver cancer and its trends from 1990 to 2019. We extracted the primary liver cancer data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to examine the mortality and morbidity of liver cancer by its etiological types, which included alcohol, viral hepatitis B and C, and non-alcoholic steatohepatitis (NASH). The data was extracted by sex and 5-year age intervals from 1990 to 2019. Data included mortality, incidence, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) of liver cancer among the Mongolian population. Mongolia had the world's highest age-standardized DALYs for liver cancer (2558.1) in 2019. Alcohol-attributable DALYs (786.6) were 29 times higher than the global average (26.1), and liver cancer due to hepatitis C (752.6) and B (763.2) were 21.5 (35.0) and 10.9 (69.1) times higher, respectively. Over the past 30 years, there has been a steady increase in the incidence and number of deaths caused by liver cancer in Mongolia. In 2019, liver cancer incidence due to alcohol consumption was 3.1 times higher for males than females, and hepatitis B was 2.7 times higher for males than females. However, the incidence of hepatitis C and NASH were slightly higher for females. Deaths from liver cancer accounted for 9.51% (2365) of total deaths in Mongolia in 2019, with a continuously increasing trend in the fraction of death compared to 1990, which was 11 times higher than the global average (0.86%), particularly in females with a 319.6% (95% UI 234.9-435.7) increase observed during the study period. Liver cancer due to hepatitis B, C, and alcohol each shared about one-third of liver cancer deaths. A comprehensive analysis of the burden of liver cancer in Mongolia reveals alcohol use as a primary cause of liver cancer mortality, particularly affecting men and significantly impacting the disease burden. Viral hepatitis continues to pose a major public health concern in the country. Although significant milestones have progressed, addressing the unique demographic and geographical challenges requires tailored approaches for specific target populations. The evidence generated from this analysis is crucial to support policy guidance, contribute to evidence-based decisions, guide public health prevention measures, and amplify population health promotion and disease prevention throughout Mongolia.

Mortality Rate and Years of Life Lost Due to Ischemic Heart Disease in Southern Iran between 2004 and 2019: A Population-Based Study.

Cardiovascular diseases (CVDs) account for one-third of all deaths worldwide. In this cross-sectional study, we extracted all death records from the Electronic Death Registration System categorized as ischemic heart disease (IHD) based on age, gender, and the year of death according to ICD-10 for this cross-sectional analysis. The Fars province is situated in southern Iran with a population of about 4 million. An analysis of years of life lost (YLL) resulting from premature death from IHD was conducted using the World Health Organization's 2015 YLL framework. The trend of the YLL rates was investigated using joinpoint regression. In the Fars province, IHD was the cause of 46969 deaths throughout a 16-year study period, (2004 to 2019). Among these, 26,503 (56.4%) were men. The crude death rates per 100000 population for men and women were 84.2 and 66.5, respectively. The total YLL due to premature death due to IHD, during the 16-year study period, was 287625 in male, 209665 in female. The joinpoint regression showed a declining trend in the YLL rate associated with premature death. Annual Percent Change (APC) was -0.6% (95% CI -6.9 to 6.1, P=0.851) for males and -1.5% (95% CI -5.2 to 2.2, P=0.418) for females. The trends of the standardized mortality rate, YLL, and crude mortality rate held steady throughout a 16-year period. Planning for comprehensive primary and secondary prevention and increasing public knowledge of IHD are necessary.

Burden of biliary tract carcinoma in China (1990–2021): Findings from the 2021 Global Burden of Disease Study

Biliary tract carcinoma (BTC) is a group of malignant tumors that originate in the digestive system and occurs with a high incidence in China. Few consistent and comparable assessments of BTC disease burden have been conducted at national or subnational levels, and little is known about the demographic, temporal, and geographic patterns of epidemiological characteristics and disease burden of BTC in China. The incidence, mortality, disability-adjusted life-years (DALYs), years of life lost (YLLs) due to premature death and years lived with disability (YLDs) of BTC were comprehensively examined by age, sex, and calendar year in the Chinese population, using the methodological framework and analytical strategies used for the 2021 Global Burden of Disease study. All-age incidence increased from 17,077 to 51,720 between 1990 and 2021, and the age-standardized incidence rate rose by 13.62%; all-age deaths increased from 17,251 to 37,833, but the age-standardized mortality rate fell by nearly one-fifth. The DALYs rose by 89.57% while the age-standardized DALY rate fell by 23.24%. Variations of the tendencies in BTC burden were found between sexes and age groups. Data for each provincial region indicate that coastal eastern provincial regions have higher incidence and YLD levels, whereas northern provincial regions have higher mortality, DALY, and YLL levels. The proportions of DALYs attributable to high body mass index (BMI) illustrate the growing attribution obesity has made, and high BMI usually puts more burden on northern provincial regions. These results provide evidence to support precise, targeted, and customed public health strategies aimed at enhancing biliary tract health among the Chinese population.

Overall mortality for community-dwelling adults over 50years at risk of malnutrition.

It is well reported that malnutrition in acute care is associated with poorer health outcomes including increased mortality. However, the consequences of malnutrition on survival in community settings is uncertain. Malnutrition in people 65years or over is often cited. Nevertheless, this study includes both middle-aged and older adults as current public health policy is highlighting the need to increase disease-free life years and is moving away from just extending life to increase overall longevity. The aim of this study is to describe the association of the risk of malnutrition using the Malnutrition Universal Screening Tool (MUST) with mortality in community-dwelling middle-aged and older adults. We used the UK Biobank to investigate the association between those at risk of malnutrition and mortality in participants aged ≥50years. MUST identified risk of malnutrition and linked data to national death registries confirmed mortality. Years of life lost (YLL) and Cox proportional hazard models with hazard ratios (HR) and confidence intervals (CI) described risk associated with all-cause mortality. There were 502408 participants recruited, 117830 were ≤50years leaving 384578 eligible participants. Based on MUST scores 63495 (16.5%) were at risk of malnutrition with 401 missing some data and excluded. Incidence of mortality for at risk participants was 755 per 100000 person-years, corresponding to 153476 YLL. Of those at risk of malnutrition, 9.5% died versus 7.8% at low risk. Initial survival analysis reported an increased risk of mortality (HR 1.29, 95% CI: 1.25 to 1.33) that decreased after adjusting for confounders (HR 1.14, 95% CI: 1.11 to 1.18) in those at risk of malnutrition versus those at low risk. Risk of malnutrition was associated with increased overall mortality. Modest effect sizes are demonstrated but are supportive of public health policies, which advocate wide-scale community, based nutritional screening for middle-aged and older adults.

Burden of schistosomiasis in global, regional, and national 1990–2019: A systematic analysis for the Global Burden of Disease Study 2019

BackgroundDespite the gradual decline of schistosomiasis due to the efforts of the WHO and various countries, with the WHO setting a goal to eliminate schistosomiasis by 2030, a comprehensive global assessment of the current status of schistosomiasis has not been conducted. ObjectivesTo provide a detailed description of the changes in schistosomiasis from 1990 to 2019 by using the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 database. MethodsWe obtained all relevant data on schistosomiasis worldwide from the Global Burden of Diseases (GBD) database from 1990 to 2019. The mortality, prevalence, disability-adjusted life-years (DALYs), Years of Life Lost (YLLs), Years Lived with Disability (YLDs) of schistosomiasis were examined by Socio-demographic Index (SDI), age, sex, and year at the global, region and national level. ResultsFrom 1990 to 2019, the age-standardized rate(ASR)-prevalence of schistosomiasis has decreased from 2600.9 per 100,000(95% uncertainty interval (UI) 2191.2 to 3059.3) to 1805.0 per 100,000(95% UI 1503.4 to 2146.9). The estimated annual percentage change (EAPC) from 1990 to 2019 was 1.28 (95% UI 1.22 to 1.33) in high SDI regions and −2.45 (95% UI −3.03 to −1.86) in low SDI regions. In North Africa and the Middle East, the most substantial reduction in DALYs occurred, with an observed EAPC of −5.36. ConclusionThe burden of schistosomiasis has decreased over the past three decades worldwide. However, the high SDI regions have shown the increasing burden of schistosomiasis. Besides, Multiple countries in Africa still bear a significant burden of schistosomiasis, necessitating robust prevention and control efforts.

Trend analysis of drowning mortality and years of life lost (YLL) in the south of Iran, 2004–2019

Background and Aims: Drowning is defined as a process with consequences ranging from death to survival without continuous injury. This study was conducted to determine the mortality rate and the years of life lost (YLL) due to drowning in Fars Province. Methods: All deaths due to drowning in Fars Province were obtained from the electronic population-based death registration system (EDRS). Crude and age-standardized mortality rate, YLL, and YLL rate data were calculated, and joinpoint regression was used to examine the trend. Results: During the study period (2004–2019), 910 deaths due to drowning occurred in Fars Province. Of these, 80.5% (733 cases) were reported in men and 41.0% (373 cases) were in the age group of 15–29 years. Crude mortality rate had decreasing trends in male and stable trends in female. The total YLL due to drowning during the 16-year study period were 19,583 (0.62 per 1000 people) in men and 4797 (0.15 per 1000 people) in women. According to the joinpoint regression analysis, the 16-year trend of YLL rate due to premature mortality in males was decreasing. The annual percent change (APC) was -6.0% [95% confidence interval (95% CI) -8.4 to -3.5, p < 0.001] and stable trends in female (APC = - 5.4%; 95% CI -11.8 to 1.4, p = 0.108). Conclusion: Although the trend of crude and standardized mortality rates and YLL due to drowning in men decreased during 2004–2019, these trends have been constant in women. Therefore, the need to invest in the implementation and evaluation of drowning prevention interventions cannot be ignored.

Burden of alcohol use disorder and its consequences in Iran from 1990 to 2019: Findings from the global burden of disease study

BackgroundThis study aimed to provide an up-to-date evaluation of the burden of alcohol use disorder and its consequences in Iran from 1990 to 2019. MethodsWe assessed the burden of alcohol use disorder and its three subsequent disorders, including cirrhosis and other chronic liver diseases, liver cancer, and cardiomyopathy using Global Burden of Disease (GBD) data. We retrieved data on incidence, prevalence, death, Years of Life Lost from mortality (YLL), Years of healthy life Lost due to Disability (YLD), and Disability-Adjusted Life Year (DALY), which is calculated by summing YLL and YLD values, indices, as well as sociodemographic index (SDI) values. ResultsAge-standardized DALY rate of alcohol use disorder reduced from 55.5 in 1990 to 41.8 per 100,000 in 2019 (−24.1 %). Similarly, age-standardized DALY rates of cirrhosis due to alcohol use (−28.7 %), liver cancer due to alcohol use (−20.9 %), and alcoholic cardiomyopathy (−36.3 %) decreased in Iran from 1990 to 2019. In 2019, alcohol use disorder had the highest DALY rate among individuals younger than 55 years, while cirrhosis due to alcohol use imposed the greatest burden on those older than 55. After adjusting for the year, SDI was negatively associated with the age-standardized DALY rate of liver cancer due to alcohol use (p < 0.001), positively associated with that of alcoholic cardiomyopathy (p = 0.002), and not significantly associated with the burden of other conditions (p > 0.05). ConclusionsDespite reductions in the age-standardized DALY rate of alcohol use disorders and related consequences among Iranians, they remain a serious public health concern in Iran.

The global burden of suicide mortality among people on the autism spectrum: A systematic review, meta-analysis, and extension of estimates from the Global Burden of Disease Study 2021

We aimed to quantify the risk, mortality, and burden of suicide among autistic persons. We searched PubMed, Embase, and PsycINFO on 5th April 2023 for sources reporting the relative risk (RR) of suicide or suicide attempt among autistic persons (PROSPERO registration: CRD42021265313). Autism spectrum prevalence and suicide mortality and years of life lost (YLLs), were sourced from the Global Burden of Disease Study 2021. RRs pooled via meta-regression and health metrics estimates were used to estimate the excess suicide mortality and YLLs among autistic persons. We sourced 983 unique studies of which ten studies met inclusion criteria, consisting of 10.4 million persons. The pooled RR for suicide for autistic persons was 2·85 (95% UI: 2·05–4·03), which was significantly higher for autistic females than autistic males. No evidence of publication bias was detected via inspection of funnel plot and Egger's test. Globally, we estimated 13 400 excess suicide deaths among autistic persons in 2021, equating to 1·8% of all suicide deaths and 621 000 excess YLLs. Studies were limited in number and geographical coverage. Effective suicide prevention strategies for autistic persons may substantially reduce the fatal burden of suicides globally and reduce the health burden experienced within this population.

Mortality Rate and Years of Life Lost Due to Breast and Gynecologic Cancers in Southern Iran 2004-2019: A Population-Based Study.

There is an increase in the incidence of breast and gynecologic cancers in Iran during the last three decades. Literature is inadequate about the Years of Life Lost (YLL) attributed to these cancers in Iran. Mortality data due to these cancers amongst females aged >20 yr from 2004 to 2019 was acquired from "Electronic Death Registry System", Fars Province, Iran. Using local health centers' databases and national census reports from 1996 to 2016, the age-standardized incidence rate (ASR) per 100,000 people were estimated. YLLs were calculated using the WHO's 2015 "YLL template". During 2004-2019, 1886 and 829 deaths occurred due to breast and gynecologic cancers, respectively. The ASR due to breast and gynecologic cancers showed a significant increasing trend (P<0.001 for each). The total YLL due to breast, cervical/uterine/vaginal/vulvar, and ovary cancers' deaths in the 16-year period were 33,077, 7,172 and 6,584 yr, respectively. The highest YLLs were observed in 50-59-year-old females, followed by 40-49- and 60-69-year-old females. The 16- year trend of YLL rate due to premature mortality in breast cancer, ovary cancer and cervix cancer was increasing: annual percent change (APC) was 7.6% (95% CI: 5.5-9.7, P<0.001), 19.0% (95% CI: 12.2-26.1, P<0.001) and 9.2% (95% CI: -9.2 to 31.3, P>0.05, respectively. Mortality rate and YLLs due to breast and gynecologic cancers have been increased in southern Iran during the last twenty years. Early detection programs and allocating treatments at early stages should be prioritized.

Mortality and disease burden of oral cancer in China: a time-trend analysis on the China Death Surveillance Database from 2006 to 2021

BackgroundOral cancer is one of the most common cancers in China and seriously threaten life and health of Chinese people. We analysed the trends and disparities of oral cancer mortality rates and the disease burden of oral cancer in China from 2006 to 2021 to provide a reference for its prevention and control.MethodsAnnual death data for oral cancer was gleaned from the China Death Surveillance Database. The age-standardized mortality rate (ASMR), annual percentage change (APC), and average APC (AAPC) were used to analyze the trend of mortality. Loss of life expectancy (LLE) and years of life lost (YLL) were adopted to assess disease burden.ResultsFrom 2006 to 2021, the overall ASMR of oral cancer lightly declined (AAPC: − 0.97%; 95% CI: − 1.89%, − 0.04%), and the similar trend was observed among females (AAPC: − 1.22%; 95% CI: − 1.89%, − 0.55%). The ASMR of males was 2.31–3.16 times higher than that of females per year. The median of LLE for overall, males and females caused by oral cancer from 2006 to 2021 were 0.05, 0.06 and 0.03 years, respectively. There was a decrease of standardized YLL rate from 2006 to 2021 for overall (AAPC: − 1.31%, 95% CI: − 2.24% ~ − 0.37%) and for female (AAPC: − 1.63%, 95% CI: − 2.30% ~ − 0.95%). ASMR in urban areas was 1.02–1.28 times higher than that in rural areas from 2006 to2011, but 0.85–0.97 times lower in urban areas than that in rural areas from 2018 to 2021. The disease burden was higher in urban areas than in rural areas in 2006, whereas the reverse was observed in 2021.ConclusionsThere are severe health gaps and disparities in trends between sexes and different areas in China. Males and rural populations need to be focused on targeted interventions for the main influencing factors.

Liver Cancer Mortality Disparities at a Fine Scale Among Subpopulations in China: Nationwide Analysis of Spatial and Temporal Trends.

China has the highest number of liver cancers worldwide, and liver cancer is at the forefront of all cancers in China. However, current research on liver cancer in China primarily relies on extrapolated data or relatively lagging data, with limited focus on subregions and specific population groups. The purpose of this study is to identify geographic disparities in liver cancer by exploring the spatial and temporal trends of liver cancer mortality and the years of life lost (YLL) caused by it within distinct geographical regions, climate zones, and population groups in China. Data from the National Death Surveillance System between 2013 and 2020 were used to calculate the age-standardized mortality rate of liver cancer (LASMR) and YLL from liver cancer in China. The spatial distribution and temporal trends of liver cancer were analyzed in subgroups by sex, age, region, and climate classification. Estimated annual percentage change was used to describe liver cancer trends in various regions, and partial correlation was applied to explore associations between LASMR and latitude. In China, the average LASMR decreased from 28.79 in 2013 to 26.38 per 100,000 in 2020 among men and 11.09 to 9.83 per 100,000 among women. This decline in mortality was consistent across all age groups. Geographically, Guangxi had the highest LASMR for men in China, with a rate of 50.15 per 100,000, while for women, it was Heilongjiang, with a rate of 16.64 per 100,000. Within these regions, the LASMR among men in most parts of Guangxi ranged from 32.32 to 74.98 per 100,000, whereas the LASMR among women in the majority of Heilongjiang ranged from 13.72 to 21.86 per 100,000. The trend of LASMR varied among regions. For both men and women, Guizhou showed an increasing trend in LASMR from 2013 to 2020, with estimated annual percentage changes ranging from 10.05% to 29.07% and from 10.09% to 21.71%, respectively. Both men and women observed an increase in LASMR with increasing latitude below the 40th parallel. However, overall, LASMR in men was positively correlated with latitude (R=0.225; P<.001), while in women, it showed a negative correlation (R=0.083; P=.04). High LASMR areas among men aligned with subtropical zones, like Cwa and Cfa. The age group 65 years and older, the southern region, and the Cwa climate zone had the highest YLL rates at 4850.50, 495.50, and 440.17 per 100,000, respectively. However, the overall trends in these groups showed a decline over the period. Despite the declining overall trend of liver cancer in China, there are still marked disparities between regions and populations. Future prevention and control should focus on high-risk regions and populations to further reduce the burden of liver cancer in China.

A Model for Estimating the Burden of Disease of Transfusion-Transmitted Infection.

Blood transfusion is an important mode of infectious disease transmission in low- and middle-income countries (LMICs). This study describes a model to determine the prevalence of transfusion-transmitted infections (TTIs) and the associated burden of disease. A five-step model was developed to determine the TTI-related burden of disease measured by disability-adjusted life years (DALYs). Uganda was selected as the study country. Approximately 298,266 units of blood were transfused in Uganda in 2019, yielding an estimated TTI incidence of 6,858 new TTIs (2.3% of transfused units) and prevalence of 19,141 TTIs (6.4% of transfused units). The total burden of disease is 2,903 DALYs, consisting of approximately 2,590years of life lost (YLLs), and 313years lived with disability (YLDs). The incidence and prevalence of TTIs and the associated burden of disease can be calculated on a local and national level. The model can be applied by health ministries to estimate the impact of TTIs in order to develop blood safety strategies to reduce the burden of disease.

Chronic Myeloid Leukemia in Bulgaria in the New Millennium: Identification of Directions for Improvement in Management and Outcomes Reporting

Background: In the last two decades, tyrosine kinase inhibitors (TKIs) and advances in molecular diagnostics have revolutionized management and long-term clinical outcomes in chronic myeloid leukemia (CML). Real-world data from different countries allow for the identification of country-specific issues in the clinical management and development of specific plans for improvement. Here, we aimed to analyze the trend in overall survival in Bulgarian CML patients since 2000. Methods: We retrieved publicly available Bulgarian CML data from several sources such as the Bulgarian National Cancer Registry, Bulgarian National Statistical Institute, and National Health Insurance Fund since 2000. We used the retrieved data of a total of 1513 Bulgarian CML patients to describe the trends in overall survival (OS), conditional overall survival, life expectancy, and life years lost over five time periods. We also described the trends in healthcare expenditures for TKIs and CML patients’ coverage with TKIs since 2014. Results: In both uni- and multivariate models, we found a constant increase in OS over the three 5-year periods until 2014. The period 2015–2019 was not associated with an additional increase in OS. Identical dynamics in the improvement in life expectancy (LE) and in life years lost (LYLs) was observed. Additionally, conditional 5-year survival did not improve during 2015–2019 in comparison to 2010–2014. Population-level data did not show consistent changes in the documented number of deaths due to CML since 2013. The period after 2013 is marked by a constant increase in the annual expenditures for TKIs, reaching to about 2.0 EUR/capita. The number of patients who received at least one TKI also increased during that period. Conclusions: After the initial significant improvement in the clinical outcomes for Bulgarian CML patients until 2014, subsequent periods did not bring further benefit in spite of the improved coverage with second- and third-line TKIs. Multiple factors may contribute to these suboptimal outcomes. Therefore, one can propose several additional measures at the country level, which could lead to additional improvement in the OS of Bulgarian CML patients.

Trauma Research Funding: An Emergency in Emergency Care.

Trauma remains a significantly underfunded area of medical research despite its status as a leading cause of death and substantial economic burden in the United States. This study explores the disparity in trauma research funding, focusing on Oklahoma compared to neighboring and populous states. Using data from the Centers for Disease Control and Prevention (CDC)'s Web-based Injury Statistics Query and Reporting System (WISQARS™) and the National Institutes of Health (NIH)'s RePORT databases, we analyzed age-adjusted years of potential life lost (YPLL) due to trauma and corresponding NIH funding across different states and nationally. Statistical analyses included bivariate comparisons and standardization of funding data per population and YPLL. From 2010 to 2020, NIH allocated approximately $124 billion nationally, with only 5% dedicated to trauma, amounting to $1,772.32 per age-adjusted YPLL. Oklahoma and Kansas exhibited the lowest NIH funding per YPLL compared to New York and California. Funding for the National Injury Prevention and Control, a subdivision of the CDC, has shown significant increases, ranking third in 2022. This study highlights the urgent need for enhanced trauma research funding to address its disproportionate impact on mortality and healthcare costs. Strategic allocation of resources is essential to advance trauma care and align research priorities with public health needs.

Global, regional, and national burdens of HIV/AIDS acquired through sexual transmission 1990-2019: an observational study.

Background Sexual transmission accounts for a substantial proportion of HIV infections. Although some countries are experiencing an upward trend in HIV infections, there has been a lack of studies assessing the global burden of HIV/AIDS acquired through sexual transmission. We assessed the global, regional, and national burdens of HIV/AIDS acquired through sexual transmission from 1990 to 2019. Methods Data on deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALY) of HIV/AIDS acquired through sexual transmission in 204 countries and territories from 1990 to 2019 were retrieved from the Global Burden of Disease Study (GBD) 2019. The burdens and trends were evaluated using the age-standardised rates (ASR) and estimated annual percentage change (EAPC). Results Globally, HIV/AIDS acquired through sexual transmission accounted for ~695.8 thousand (95% uncertainty interval 628.0-811.3) deaths, 33.0million (28.7-39.9) YLLs, 3.4million (2.4-4.6) YLDs, and 36.4million (32.2-43.1) DALYs in 2019. In 2019, Southern sub-Saharan Africa (11350.94), Eastern sub-Saharan Africa (3530.91), and Western sub-Saharan Africa (2037.74) had the highest ASR of DALYs of HIV/AIDS acquired through sexual transmission per 100,000. In most regions of the world, the burden of HIV/AIDS acquired through sexual transmission has been increasing from 1990 to 2019, mainly in Oceania (EAPC 17.20, 95% confidence interval 12.82-21.75), South Asia (9.00, 3.94-14.30), and Eastern Europe (7.09, 6.35-7.84). Conclusions HIV/AIDS acquired through sexual transmission results in a major burden globally, regionally, and nationally.
