BACKGROUND: Fungal skin diseases are common skin diseases with a heterogeneous distribution worldwide.
OBJECTIVE: This study aimed to analyse the spatiotemporal trends in the burden of fungal skin diseases at global, regional, and national levels from 1990 to 2021.
METHODS: Based on the data obtained from the Global Burden of Disease Study (GBD) 2021, we described the incident cases, prevalent cases, number of disability-adjusted life years (DALYs), and corresponding age-standardised rates (ASRs) for fungal skin diseases in 1990 and 2021 by sex, age, socio-demographic index (SDI), 21 GBD regions, and 204 countries and territories. We used Joinpoint regression analysis to assess the temporal trends in burden of fungal skin diseases during 1990 to 2021. Spearman\'s rank test was used to analyse the relationship between disease burden and potential factors.
RESULTS: From 1990 to 2021, the incident cases, prevalent cases, and DALYs for fungal skin diseases worldwide increased by 67.93%, 67.73%, and 66.77%, respectively. Globally, the age-standardised incidence rate (ASIR), age-standardised prevalence rate (ASPR), and age-standardised DALYs rate (ASDR) for fungal skin diseases in 2021 were 21668.40 per 100,000 population (95% UI: 19601.19-23729.17), 7789.55 per 100,000 population (95% UI: 7059.28-8583.54), and 43.39 per 100,000 population (95% UI: 17.79-89.10), respectively. Between 1990 and 2021, the ASIR, ASPR, and ASDR for fungal skin diseases have modestly increased, with AAPC of 11.71% (95% confidence interval [CI]: 11.03%-12.39%), 19.24% (95% CI: 18.12%-20.36%), and 20.25% (95% CI: 19.33%-21.18%), respectively. Males experienced a higher burden of fungal skin diseases than females. The incident cases, prevalent cases, and DALYs for fungal skin diseases were highest at the age of 5-9, while the ASRs were highest among the elderly. At national level, the highest ASRs were observed in Nigeria, Ethiopia, and Mali. Overall, SDI was negatively correlated with the ASRs, whereas Global Land-Ocean Temperature Index (GLOTI) was remarkably positively correlated with the burden of fungal skin diseases.
CONCLUSIONS: Between 1990 and 2021, the global burden of fungal skin diseases has increased, causing a high disease burden worldwide, particularly in underdeveloped regions and among vulnerable population such as children and the elderly. With global warming and aging of the population, the burden of fungal skin diseases may continue to increase in the future. Targeted and specific measures should be taken to address these disparities and the ongoing burden of fungal skin diseases.

BACKGROUND: Migraine, a widespread neurological condition, substantially affects the quality of life, particularly for adolescents and young adults. While its impact is significant, there remains a paucity of comprehensive global research on the burden of migraine in younger demographics. Our study sought to elucidate the global prevalence, incidence, and disability-adjusted life-years (DALYs) associated with migraine in the 15-39 age group from 1990 to 2021, utilizing data from the Global Burden of Disease (GBD) 2021 study.
METHODS: Our comprehensive study analyzed migraine data from the GBD 2021 report, examining the prevalence, incidence, and DALYs across 204 countries and territories over a 32-year span. We stratified the information by age, sex, year, geographical region, and Socio-demographic Index (SDI). To evaluate temporal trends in these metrics, we employed the estimated annual percentage change (EAPC) calculation.
RESULTS: Between 1990 and 2021, the worldwide prevalence of migraine among 15-39 year-olds increased substantially. By 2021, an estimated 593.8 million cases were reported, representing a 39.52% rise from 425.6 million cases in 1990. Global trends showed increases in age-standardized prevalence rate, incidence rate, and DALY rate for migraine during this period. The EAPC were positive for all three metrics: 0.09 for ASPR, 0.03 for ASIR, and 0.09 for DALY rate. Regions with medium SDI reported the highest absolute numbers of prevalent cases, incident cases, and DALYs in 2021. However, high SDI regions demonstrated the most elevated rates overall. Across the globe, migraine prevalence peaked in the 35-39 age group. Notably, female rates consistently exceeded male rates across all age categories.
CONCLUSIONS: The global impact of migraine on youths and young adults has grown considerably from 1990 to 2021, revealing notable variations across SDI regions, countries, age groups, and sexes. This escalating burden necessitates targeted interventions and public health initiatives, especially in areas and populations disproportionately affected by migraine.

UNASSIGNED: To identify the long-term spatiotemporal trend of ozone-related chronic obstructive pulmonary disease (COPD) burden by sex and country and to explore potential drivers.
UNASSIGNED: We retrieved data of ozone-related COPD death and disability adjusted life year (DALY) from the Global Burden of Disease 2019. We used a linear regression of natural logarithms of age-standardized rates (ASRs) with calendar year to examine the trends in ASRs and a panel regression to identify country-level factors associated with the trends.
UNASSIGNED: Global ozone-attributable COPD deaths increased from 117,114 to 208,342 among men and from 90,265 to 156,880 among women between 1990 and 2019. Although ASRs of ozone-related COPD death and DALY declined globally, they increased in low and low-middle Socio-demographic Index (SDI) regions, with faster rise in women. Elevated average maximum temperature was associated with higher ozone-attributable COPD burden, while more green space was associated with lower burden.
UNASSIGNED: More efforts are needed in low and low-middle SDI regions, particularly for women, to diminish inter-country inequality in ozone-attributable COPD. Global warming may exacerbate the burden. Expanding green space may mitigate the burden.

Purpose: Identifying the burden of disease related to plastic and reconstructive surgery in Canada will provide timely population-based data, inform policy, and generate support for research funding. Methods and Patients: Data on the burden of disease (ie, prevalence, incidence, mortality, years of life lost, years lived with disability, and disability-adjusted life years [DALYs]), were extracted from the Global Burden of Disease 2019 results tool for all available and relevant plastic surgery diseases. The economic burden of disease in Canadian dollars was calculated based on prior studies. Data are presented as either rates (per 100 000) or counts with the associated uncertainty interval. Results: In 2019, plastic surgery related conditions in Canada had an overall age-standardized DALY rate of 556 per 100 000 [463-664]. Of these conditions, breast cancer was responsible for approximately 50% of the overall burden of disease, with an age-standardized DALY rate of 268 per 100 000 [244-294] followed by squamous cell carcinoma (66 per 100 000 [45-94]) and thermal burns (61 per 100 000 [46-82]). Age-standardized incidence rates were highest for cellulitis (2654 per 100 000 [2502-2812]). Breast cancer had the highest age-standardized cost of care of all plastic surgery related diseases, at $5.1 billion, approximately half of the total age-standardized cost of $10.6 billion for included plastic surgery diseases. Conclusion: Plastic and reconstructive surgery related diseases, particularly breast cancer, thermal burns, and malignant melanoma, are responsible for a high burden of disease and significant cost to the Canadian healthcare system. These results will help guide national healthcare policy and should provide support to directing funding and research efforts toward impactful diseases facing the Canadian healthcare system.
Objectif: L’identification de la morbidité des maladies liées à la chirurgie plastique et reconstructrice au Canada fournira des données en temps opportun reposant sur la population, permettra de renseigner les politiques et générer un soutien pour le financement de la recherche. Méthodes et patients: Des données sur la morbidité des maladies (c.-à-d. prévalence, incidence, mortalité, années de vie perdues [YLL], années vécues avec une invalidité [YLD], et années de vie corrigées pour l’invalidité [AVCI ou DALY]) ont été extraites de l’outil de résultats sur la morbidité mondiale des maladies 2019 pour toutes les affections disponibles et pertinentes pour la chirurgie plastique. Le poids économique de la maladie en dollars canadiens (CAD) a été calculé sur la base d’études antérieures. Les données sont présentées sous forme de taux (pour 100 000) ou de nombres avec les intervalles d’incertitude (IdI) associés. Résultats: En 2019, les troubles liés à la chirurgie plastique au Canada avaient un taux d’AVCI global standardisé pour l’âge de 556 pour 100 000 (463-664). Parmi ces affections, le cancer du sein était responsable d’environ 50% du fardeau global de la maladie avec un taux d’AVCI standardisé pour l’âge de 268 pour 100 000 (244-294) suivi du cancer épidermoïde (carcinome à cellules squameuses) (66 pour 100 000 [45-94]) et des brûlures thermiques (61 pour 100 000 [46-82]). Les incidences standardisées pour l’âge étaient les plus élevées pour la cellulite (2 654 pour 100 000 [2 502-2 812]). Le cancer du sein avait le coût des traitements standardisé pour l’âge le plus élevé de toutes les maladies liées à la chirurgie plastique, avec 5,1 milliards de dollars, soit environ la moitié des dépenses totales standardisées pour l’âge de 10,6 milliards de dollars pour les maladies incluses liées à la chirurgie plastique. Conclusion: Les maladies liées à la chirurgie plastique et reconstructrive, et plus particulièrement le cancer du sein, les brûlures thermiques et le mélanome malin, sont responsables d’une importante morbidité et de coûts significatifs pour le système de santé canadien. Ces résultats aideront à guider la politique nationale de soins de santé et devraient fournir un soutien pour orienter le financement et les efforts de recherche vers des maladies ayant les plus grandes répercussions sur le système de soins de santé canadien. Mots-clés: chirurgie plastique, morbidité, années de vie corrigées pour l’invalidité, fardeau global de la maladie, coût des soins, morbidité de la maladie.

BACKGROUND: The objective of this study is to estimate the burden of selected immunization-preventable infectious diseases in Spain using the Burden of Communicable Diseases in Europe (BCoDE) methodology, as well as focusing on the national immunization programme and potential new inclusions.
METHODS: The BCoDE methodology relies on an incidence and pathogen-based approach to calculate disease burden via disability-adjusted life year (DALY) estimates. It considers short and long-term sequelae associated to an infection via outcome trees. The BCoDE toolkit was used to populate those trees with Spanish-specific incidence estimates, and de novo outcome trees were developed for four infections (herpes zoster, rotavirus, respiratory syncytial virus [RSV], and varicella) not covered by the toolkit. Age/sex specific incidences were estimated based on data from the Spanish Network of Epidemiological Surveillance; hospitalisation and mortality rates were collected from the Minimum Basic Data Set. A literature review was performed to design the de novo models and obtain the rest of the parameters. The methodology, assumptions, data inputs and results were validated by a group of experts in epidemiology and disease modelling, immunization and public health policy.
RESULTS: The total burden of disease amounted to 163.54 annual DALYs/100,000 population. Among the selected twelve diseases, respiratory infections represented around 90% of the total burden. Influenza exhibited the highest burden, with 110.00 DALYs/100,000 population, followed by invasive pneumococcal disease and RSV, with 25.20 and 10.57 DALYs/100,000 population, respectively. Herpes zoster, invasive meningococcal disease, invasive Haemophilus influenza infection and hepatitis B virus infection ranked lower with fewer than 10 DALYs/100,000 population each, while the rest of the infections had a limited burden (< 1 DALY/100,000 population). A higher burden of disease was observed in the elderly (≥ 60 years) and children < 5 years, with influenza being the main cause. In infants < 1 year, RSV represented the greatest burden.
CONCLUSIONS: Aligned with the BCoDE study, the results of this analysis show a persisting high burden of immunization-preventable respiratory infections in Spain and, for the first time, highlight a high number of DALYs due to RSV. These estimates provide a basis to guide prevention strategies and make public health decisions to prioritise interventions and allocate healthcare resources in Spain.

UNASSIGNED: This study aimed to quantify the global cardiovascular disease (CVD) burden attributable to diet high in sugar-sweetened beverages (SSB) among adults aged 60 years and older using data from the Global Burden of Disease (GBD) Study 2019.
UNASSIGNED: We extracted data on CVD mortality, disability-adjusted life-years (DALYs), and risk-factor exposures from the GBD 2019 study for people aged 60 and older. Age-period-cohort models were used to estimate the overall annual percentage change in mortality and DALY rate (net drift, % per year), mortality and DALY rate for each age group from 1990 to 2019 (local drift, % per year), longitudinal age-specific rate corrected for period bias (age effect), and mortality and Daly rate for each age group from 1990 to 2019 (local drift, % per year). And period/cohort relative risk (period/cohort effect).
UNASSIGNED: Between 1990 and 2019, global age-standardized CVD mortality (ASMR) and disability-adjusted life years (DALY) rates attributable to high SSB intake decreased, with larger reductions in high-SDI regions. ASMR declined from 19.5 to 13 per 100,000 (estimated annual percentage change (EAPC): -1.46%) and ASDR declined from 345.8 to 220.6 per 100,000 (EAPC: -1.66%). Age-period-cohort analysis showed CVD deaths and DALYs increased exponentially with age, peaking at 85-89 years. Period effects indicated declining CVD mortality and DALY rates since 1999, especially in higher-SDI regions. Cohort effects demonstrated consistent risk declines across successive generations born between 1900 and 1959. Predictions suggest continuing decreases through 2045 globally, but slower declines in lower-SDI regions.
UNASSIGNED: In conclusion, this comprehensive assessment of global CVD burden among older adults attributable to high SSB intake highlights major achievements but also persistent areas needing attention. Favorable declining mortality and DALY rate trends reflect substantial progress in CVD control amid population growth and aging.

UNASSIGNED: Given the rapidly growing burden of cardiovascular disease (CVD) in Asia, this study forecasts the CVD burden and associated risk factors in Asia from 2025 to 2050.
UNASSIGNED: Data from the Global Burden of Disease 2019 study was used to construct regression models predicting prevalence, mortality, and disability-adjusted life years (DALYs) attributed to CVD and risk factors in Asia in the coming decades.
UNASSIGNED: Between 2025 and 2050, crude cardiovascular mortality is expected to rise 91.2% despite a 23.0% decrease in the age-standardised cardiovascular mortality rate (ASMR). Ischaemic heart disease (115 deaths per 100,000 population) and stroke (63 deaths per 100,000 population) will remain leading drivers of ASMR in 2050. Central Asia will have the highest ASMR (676 deaths per 100,000 population), more than three-fold that of Asia overall (186 deaths per 100,000 population), while high-income Asia sub-regions will incur an ASMR of 22 deaths per 100,000 in 2050. High systolic blood pressure will contribute the highest ASMR throughout Asia (105 deaths per 100,000 population), except in Central Asia where high fasting plasma glucose will dominate (546 deaths per 100,000 population).
UNASSIGNED: This forecast forewarns an almost doubling in crude cardiovascular mortality by 2050 in Asia, with marked heterogeneity across sub-regions. Atherosclerotic diseases will continue to dominate, while high systolic blood pressure will be the leading risk factor.

Ischemic heart disease (IHD) is a condition in which the heart is starved of oxygen. Knowing the dietary risk factors implementing appropriate nutritional interventions in this regard seems essential. Therefore, the present study was carried out to determine the epidemiological features of IHD affected by dietary risks. This study used data from the Global Burden of Disease (GBD) study. In this study, we collected information on death, years lived with disability (YLD), and disability-adjusted life years (DALYs) of IHD affected by dietary risks in one hundred thousand people with 95% confidence based on the direct Age Standard Rate (ASR). We applied these data based on the Socio-demographic Index (SDI). In 2019, the number of IHD deaths, YLDs, and DALYs attributable to dietary risks was 62.43 million (95% UI [50.97-73.63] per 100,000 population), 36.88 (95% UI [23.87-53.32] per 100,000 population), and 1271.32 (95% UI [1061.29-1473.75] per 100,000 population), respectively. We found that the lowest DALYs of IHD affected by dietary risks by ASR are for high SDI countries. Most dietary risk factors related to IHD in countries with high and high middle SDI were related to a diet high in red and processed meat, sodium, and low in legumes, but in countries with low and low middle SDI, it was related to a diet low in fiber, fruit, nuts and seeds, PUFA, seafood W3 fatty acids, vegetables and whole grain. Considering that the dietary risk factors related to IHD are different based on SDI, it is necessary to consider nutritional interventions according to SDI.

Due to the essential role of calcium in vital biological functions, diet low in calcium (DLC) is associated with various diseases. However, there is a lack of study about the current prevalence and health burden due to DLC using reliable data sources.
We used data from the Global Burden of Disease study 2019 (GBD 2019) to estimate the prevalence and health burden of DLC in 204 countries from 1990 to 2019, by age, sex, and sociodemographic index (SDI). The estimates were produced in DisMod-MR 2.1, a Bayesian meta-regression tool. Summary exposure value (SEV) was used to show the prevalence of DLC, while diseases adjusted life year (DALY) was used to represent the disease burden. The disease burden was estimated for DLC-induced colorectal cancer. Spearman Rank Order correlation was used for correlation analysis, and estimated annual percentage (EAPC) was used to reflect the temporal trends.
From 1990 to 2019, the global prevalence of DLC decreased (EAPC of SEV, -0.47; 95% CI, -0.5 to -0.43), but have increased in Oceania region and in many countries, such as United Arab Emirates, New Zealand, Japan, and France. The global DALYs associated with low in calcium were estimated to be 3.14 million (95% uncertainty interval (UI), 2.25-4.26 million) in 2019, with an age standardized rate of 38.2 (95% UI, 27.2-51.8) per 100,000. Unlike the prevalence, the global age standardized DALY rates has remained unchanged (EAPC, -0.03; 95% CI, -0.12 to 0.07), but has increased in over 80 of the 204 countries, located mainly in Asia, Africa, and South America. In all years and regions, the age standardized SEV and DALY rates were higher in male people than that in female people. The prevalence (rho = -0.823; P < 0.001) and disease burden (rho = -0.433; P < 0.001) associated with diet in low calcium were strongly correlated to SDI. The prevalence decreased with age, but the DALY rates increased with age and peaked at about 90 years. The prevalence of DLC has decreased worldwide and in most countries, but the disease burden of DLC induced colorectal cancer has increased in over 40% of countries worldwide.
Countries with low sociodemographic level and male people are more likely to experience the risk of DLC and related disease burden. Related measures in improve dietary calcium intake are in need to address diet in low calcium related health problems.

UNASSIGNED: Few studies have investigated near vision loss (NVL) in China. To address this gap, we aimed to explore trends in the prevalence and disease burden of NVL from 1990 to 2019 and to predict trends over the next decade.
UNASSIGNED: Using data from the Global Burden of Disease 2019 study, we calculated the age-standardised prevalence rate (ASPR), age-specific disability-adjusted life years (DALYs), and annual percentage change (EAPC) in China and different regions. We then used the Bayesian age-period-cohort (BAPC) predictive model to predict the prevalence trends from 2020 to 2030 in both contexts.
UNASSIGNED: At the global level, ASPRs increased from 5613.27 in 1990 to 5937.81 per 100 000 population in 2019, with an EAPC of 0.06. The ASPR in China specifically decreased from 7538.14 in 1990 to 7392.86 per 100 000 population in 2019 (EAPC = -0.02). The age-standardised DALY rate was higher in women than in men, both globally and in China. The NVL burden was relatively higher in low-income regions, low sociodemographic index regions, and the South-East Asia Region compared to other regions. The predictive model indicated that the ASR trend for NVL slowly increased at a global level after 2020, yet decreased in China.
UNASSIGNED: Despite a decline in the age-standardised prevalence of NVL in China over the next decade, the current burden remains substantial. To alleviate this burden, decision-makers should adopt inclusive approaches by involving all stakeholders.
