RESUMO
This study aimed to investigate the estimated burden attributed to lead exposure (LE), at the national and subnational levels from 1990 to 2019 in Iran. The burden attributed to LE was determined through the estimation of deaths, disability-adjusted life years (DALYs), years of life lost (YLLs) and years lived with disability (YLDs) using the comparative risk assessment method of Global Burden of Disease (GBD) study presenting as age-standardized per 100,000 person year (PY) with 95% uncertainty intervals (95% UI). Furthermore, the burden of each disease were recorded independently. Eventually, the age-standardized YLLs, DALYs, deaths and YLDs rates attributed to LE demonstrated a decrease of 50.7%, 48.9%, 38.0%, and 36.4%, respectively, from 1990 to 2019. The most important causes of LE burden are divided into two acute and chronic categories: acute, mainly causes mental disorders (DALYs rate of 36.0 in 2019), and chronic, results in cardiovascular diseases (CVDs) (DALYs rate of 391.8) and chronic kidney diseases (CKDs) (DALYs rate of 26.6), with CVDs bearing the most significant burden. At the sub-national level, a decrease in burden was evident in most provinces; moreover, low and low-middle SDI provinces born the highest burden. The burden increased mainly by ageing and was higher in males than females. It was concluded that although the overall decrease in the burden; still it is high, especially in low and low-middle SDI provinces, in advanced ages and in males. Among IDID, CKDs and CVDs that are the most important causes of LE-attributed burden in Iran; CVDs bear the highest burden.

BACKGROUND: Diabetes frequently results in the need for multiple medication therapies, known as 'Polypharmacy'. This situation can incur significant costs and increase the likelihood of medication errors. This study evaluated the prescriptions of patients with diabetes regarding polypharmacy to assess its effect on the control of hemoglobin A1c (HbA1c) levels and prescription costs. METHODS: A cross-sectional national study was conducted based on data from linking the Iranians Health Insurance Service prescriptions in 2015 and 2016 with the STEPS 2016 survey in Iran. The association of the individual and sociodemographic factors, as well as polypharmacy, as independent variables, with control of HbA1c levels and the cost of the prescriptions were assessed among diabetic patients using logistic and linear regression, respectively. RESULTS: Among 205 patients using anti-diabetic medications, 47.8% experienced polypharmacy. The HbA1c of 74 patients (36.1%) was equal to or less than 7, indicating controlled diabetes. HbA1c control showed no significant association with gender. However, prescription costs were notably lower in females (ß=0.559 [0.324â0.964], P=0.036). No significant correlation was found between the area of residence and prescription costs, but HbA1c was significantly more controlled in urban areas (OR=2.667 [1.132â6.282], P=0.025). Prescription costs were significantly lower in patients without polypharmacy (ß=0.211, [0.106â0.423], P<0.001), though there was no significant association between polypharmacy and HbA1c levels. CONCLUSION: Our results demonstrated that diabetics with polypharmacy paid significantly more for their prescriptions without experiencing a positive effect on the control of HbA1c levels.

BACKGROUND: Oral disorders are still a major global public health challenge, considering their perpetuating and chronic nature. Currently, there is no direct index to measure the quality of care on a population scale. Hence, we aim to propose a new index to measure the quality of care for oral disorders worldwide. METHODS: We generated our database using the data from the Global Burden of Disease (GBD) study 2017. Among different variables such as prevalence, incidence, years lived with disability, and disability-adjusted life years, we utilised principal component analysis (PCA) to determine the component that bears the greatest proportion of information to generate the novel quality of care index (QCI) for oral disorders. RESULTS: Global QCI for oral disorders gradually increased from 1990 to 2017 (from 70.5 to 74.6). No significant gender disparity was observed during this period, and the gender disparity ratio (GDR) was considered optimal in 1990 and 2017. Between 1990 and 2017, the age-standardised QCI for all oral disorders increased in all the SDI regions. The highest QCI for all oral disorders in 2017 belonged to high-middle SDI countries (=80.24), and the lowest YLDs rate was seen in the low SDI quintile. In 1990, the quality of care in European, Central Asian, and Central and South American countries was in the lowest quintiles, whereas the North American, East Asian, Middle Eastern, and some African countries had the highest quality of dental care. Maynmar (=100), Uganda (=92.5), Taiwan (=92.0), China (=92.5), and the United States (=89.2) were the five countries with the highest age-standardised QCI. Nicaragua (=41.3), Belgium (=40.2), Venezuela (=38.4), Sierra Leone (=30.5), and the Gambia (=30.3) were the five countries with the least age-standardised QCI values. CONCLUSION: The quality of care for all oral disorders showed an increasing trend on a global scale from 1990 to 2017. However, the QCI distribution was not homogenous among various regions. To prevent the exacerbation of imminent disparities in this regard, better attention to total tooth loss in high-income countries and prioritising primary healthcare provision in low-income countries are recommended for oral disorders.

Kidney cancer (KC) is a prevalent cancer worldwide. The incidence and mortality rates of KC have risen in recent decades. The quality of care provided to KC patients is a concern for public health. Considering the importance of KC, in this study, we aim to assess the burden of the disease, gender and age disparities globally, regionally, and nationally to evaluate the quality and inequities of KC care. The 2019 Global Burden of Disease study provides data on the burden of the KC. The secondary indices, including mortality-to-incidence ratio, disability-adjusted life years -to-prevalence ratio, prevalence-to-incidence ratio, and years of life lost-to-years lived with disability ratio, were utilized. These four newly merged indices were converted to the quality-of-care index (QCI) as a summary measure using principal component analysis. QCI ranged between 0 and 100, and higher amounts of QCI indicate higher quality of care. Gender disparity ratio was calculated by dividing QCI for females by males to show gender inequity. The global age-standardized incidence and mortality rates of KC increased by 29.1% (95% uncertainty interval 18.7-40.7) and 11.6% (4.6-20.0) between 1990 and 2019, respectively. Globally, the QCI score for KC increased by 14.6% during 30 years, from 71.3 to 81.6. From 1990 to 2019, the QCI score has increased in all socio-demographic index (SDI) quintiles. By 2019, the highest QCI score was in regions with a high SDI (93.0), and the lowest was in low SDI quintiles (38.2). Based on the World Health Organization regions, the QCI score was highest in the region of America, with Canada having the highest score (99.6) and the lowest in the African Region, where the Central African Republic scored the lowest (17.2). In 1990, the gender disparity ratio was 0.98, and in 2019, it was 0.97 showing an almost similar QCI score for females and males. Although the quality of care for KC has improved from 1990 to 2019, there is a significant gap between nations and different socioeconomic levels. This study provides clinicians and health authorities with a global perspective on the quality of care for KC and identifies the existing disparities.

BACKGROUND AND OBJECTIVE: Cervical cancer is the most preventable and ovarian cancer is the most lethal gynecological cancer. However, in the world, there are disparities in health care performances resulting in differences in the burden of these cancers. The objective of this study was to compare the health-system quality of care and inequities for these cancers using the Quality of Care Index (QCI). MATERIAL AND METHODS: The 1990-2019 data of the Global Burden of Disease (GBD) was analyzed to extract rates of incidence, prevalence, mortality, Disability-Adjusted Life Years (DALYs), Years of Life Lost (YLL), and Years of healthy life lost due to disability (YLD) of cervical and ovarian cancer. Four indices were developed as a proxy for the quality of care using the above-mentioned rates. Thereafter, a Principal Components Analysis (PCA) was applied to construct the Quality of Care Index (QCI) as a summary measure of the developed indices. RESULTS: The incidence of cervical cancer decreased from 1990 to 2019, whereas the incidence of ovarian cancer increased between these years. However, the mortality rate of both cancers decreased in this interval. The global age-standardized QCI for cervical cancer and ovarian cancer were 43.1 and 48.5 in 1990 and increased to 58.5 and 58.4 in 2019, respectively. QCI for cervical cancer and ovarian cancer generally decreased with aging, and different age groups had inequitable QCIs. Higher-income countries generally had higher QCIs for both cancers, but exceptions were also observed. CONCLUSIONS: Uncovering disparities in cervical and ovarian cancer care across locations, Socio-Demographic Index levels, and age groups necessitate urgent improvements in healthcare systems for equitable care. These findings underscore the need for targeted interventions and prompt future research to explore root causes and effective strategies for narrowing these gaps.

BACKGROUND: Chronic kidney disease (CKD) imposes a heavy obscure burden on individuals and health systems. Besides its burden, the quality of care of CKD is less well investigated. In this study, we aimed to explore the global, regional and national trends of CKD burden and quality of care. METHODS: The Global Burden of Disease Study 2019 data were used. Trends of incidence, prevalence, deaths and disability-adjusted life years were studied for the 1990-2019 period in the global aspect. By generating four secondary indices to assess different aspects of quality of care the quality of care index (QCI) was developed to explore the care provided for CKD. Inequities and disparities between various geographic, socio-demographic and age stratifications, and sex were studied using the QCI values. RESULTS: In 2019, there were 18 986 903 (95% uncertainty interval 17 556 535 to 20 518 156) incident cases of CKD, globally. The overall global QCI score had increased slightly from 78.4 in 1990 to 81.6 in 2019, and it was marginally better in males (QCI score 83.5) than in females (80.3). The highest QCI score was observed in the European region with a score of 92.5, while the African region displayed the lowest QCI with 61.7. Among the age groups, the highest QCI was for children aged between 5 and 9 years old (92.0), and the lowest was in the age group of 20-24 year olds (65.5). CONCLUSIONS: This study revealed that significant disparities remain regarding the quality of care of CKD, and to reach better care for CKD, attention to and care of minorities should be reconsidered. The evidence presented in this study would benefit health policymakers toward better and more efficient control of CKD burden alongside improving the care of this condition.

Purpose: While many studies have reported hypertension (HTN) and pre-hypertension (PHTN) in large geographic locations of Iran, information regarding district levels is missing. We aimed to examine inequalities in the prevalence of hypertension, prehypertension, anti-hypertensive coverage, awareness, and effective treatment of adults in districts of Iran. Methods: We used 27,165 participants' data from the STEPS 2016 study in Iran. A small area estimation model was carried out to predict HTN in the 429 districts of Iran. HTN and PHTN were defined based on the American Heart Association Guideline. Awareness of being hypertensive, treatment coverage, and effective treatment were also estimated. Results: HTN's crude prevalence was estimated to be in the range of 11.5-42.2% in districts. About PHTN, it was estimated to be 19.9-56.1%. Moreover, for awareness, treatment coverage, and effective treatment crude estimates ranged from 24.3 to 79.9%, 9.1 - 64.6%, and 19.5 - 68.3%, respectively, indicating inequalities in the distribution of aforementioned variables in 429 districts of Iran. Overall, better conditions were detected in central geographical locations and in females. Conclusion: The inequality of increased blood pressure disorder and related measures are high in districts of Iran and pave the way for policymakers and local health organizers to use the findings of this study to address the inequity of existing resources and improve HTN control.

RESUMO
BACKGROUND: The aim of this study was to examine the quality of care by age and gender in oesophageal cancer using Global Burden of Disease (GBD) database. METHODS: Patients aged 20 and over with oesophageal cancer were included in this longitudinal study using GBD 1990-2019 data. We used the Socio-Demographic Index (SDI) to classify the regions. We used Principal Component Analysis (PCA) method to calculate the Quality of Care Index (QCI). The QCI was rescaled into a 0-100 single index, demonstrating that the higher the score, the better the QC. RESULTS: The age-standardized QCI for oesophageal cancer dramatically increased from 23.5 in 1990 to 41.1 in 2019 for both sexes, globally. The high SDI regions showed higher QCI than the rest of the regions (45.1 in 1990 and 65.7 in 2019) whereas the low SDI regions had the lowest QCI, which showed a 4.5% decrease through the years (from 13.3 in 1990 to 12.7 in 2019). Globally, in 2019, the QCI showed the highest scores for patients aged 80-84, reported 48.2, and the lowest score for patients aged 25-29 reported 31.5, for both sexes. Globally, in 2019, age-standardized Gender Disparity Ratio (GDR) was 1.2, showing higher QCI in females than males. CONCLUSION: There were fundamental differences in the QCI both globally and regionally between different age groups as well as between males and females. To achieve the goal of providing high-quality services equally to people in need in all over the world, health systems need to invest in effective diagnostic services, treatments, facilities, and equipment and to plan for screening and surveillance of high-risk individuals.

BACKGROUND: Multiple sclerosis (MS) is a common neurologic autoimmune disorder. We have used a newly introduced measure, Quality of Care Index (QCI), which is associated with the efficacy of care given to patients suffering from MS. OBJECTIVES: The aims of the study were to report and compare the quality of care given to MS patients in different regions and country. METHODS: Primary measures were retrieved from Global Burden of Disease (GBD) from 1990 to 2019. Secondary measures (mortality-to-incidence ratio, DALY-to-prevalence ratio, prevalence-to-incidence ratio, and YLL-to-YLD ratio) were combined using principal component analysis, to form an essential component (QCI) (0-100 index with higher values representing better condition). RESULTS: In 2019, there were 59,345 (95% UI: 51,818-66,943) new MS incident cases globally. Global QCI of 88.4 was calculated for 2019. At national level, Qatar had the highest quality of care (100) followed by Kuwait (98.5) and Greenland (98.1). The lowest QCI was observed in Kiribati (13.5), Nauru (31.5), and Seychelles (36.3), respectively. Most countries have reached gender equity during the 30 years. Also, QCI was lowest in ages from 55 to 80 in global scale. CONCLUSION: MS QCI is better among those countries of higher socioeconomic status, possibly due to better healthcare access and early detection in these regions. Countries could benefit from adopting the introduced QCI to evaluate the quality of care given to MS patients at national and global level.

BACKGROUND: We aimed to estimate the prevalence of physical inactivity in all districts of Iran and the disparities between subgroups defined by various measures. METHODS: Small area estimation method was employed to estimate the prevalence of physical inactivity in districts based on the remaining districts in which data on the level of physical inactivity were available. Various comparisons on the estimations were done based on socioeconomic, sex, and geographical stratifications to determine the disparities of physical inactivity among districts of Iran. RESULTS: All districts of Iran had a higher prevalence of physical inactivity compared with the world average. The estimated prevalence of physical inactivity among all men in all districts was 46.8% (95% uncertainty interval, 45.9%-47.7%). The highest and lowest estimated disparity ratio of physical inactivity were 1.95 and 1.14 in males, and 2.25 and 1.09 in females, respectively. Females significantly had a higher prevalence of 63.5% (62.7%-64.3%). Among both sexes, the poor population and urban residents significantly had higher prevalence of physical inactivity than rich population and rural residents, respectively. CONCLUSIONS: The high prevalence of physical inactivity among Iranian adult population suggests the urgent need to adopt population-wide action plans and policies to handle this major public health problem and avert the probable burden.

OBJECTIVE: This study aims to assess geographic inequalities in the prevalence, awareness of diagnosis, treatment coverage and effective control of diabetes in 429 districts of Iran. METHODS: A modelling study by the small area estimation method, based on a nationwide cross-sectional survey, Iran STEPwise approach to surveillance (STEPS) 2016, was performed. The modelling estimated the prevalence, awareness of diagnosis, treatment coverage, and effective control of diabetes in all 429 districts of Iran based on data from available districts. The modelling results were provided in different geographical and socio-economic scales to make the comparison possible across the country. RESULTS: In 2016, the prevalence of diabetes ranged from 3.2 to 19.8% for women and 2.4 to 19.1% for men. The awareness of diagnosis ranged from 51.9 to 95.7% for women and 35.7 to 100% for men. The rate of treatment coverage ranged from 37.2 to 85.6% for women and 24.4 to 80.5% for men. The rate of effective control ranged from 12.1 to 63.6% for women and 12 to 73% for men. The highest treatment coverage rates belonged to Ardebil for women and Shahr-e-kord for men. The highest effective control rates belonged to Sanandaj for women and Nehbandan for men. Across Iran districts, there were considerable differences between the highest and lowest rates of prevalence, diagnosis awareness, treatment coverage, and effective control of diabetes. The concentration indices of diabetes prevalence, awareness of diagnosis, and treatment coverage were positive and significant for both sexes. CONCLUSION: Findings of this study highlight the existence of inequalities in diagnosis awareness, treatment coverage, and effective control of diabetes in all Iran regions. More suitable population-wide strategies and policies are warranted to handle these inequalities in Iran.

BACKGROUND: Breast cancer (BC), as the top neoplasm in prevalence and mortality in females, imposes a heavy burden on health systems. Evaluation of quality of care and management of patients with BC and its responsible risk factors was the aim of this study. METHODS: We retrieved epidemiologic data of BC from the Global Burden of Disease (GBD) 1990-2019 database. Epidemiology and burden of BC and its risk factors were explored besides the Quality of Care Index (QCI) introduced before, to assess the provided care for patients with BC in various scales. Provided care for BC risk factors was investigated by their impact on years of life lost and years lived with disability by a novel risk factor quality index (rQCI). We used the socio-demographic index (SDI) to compare results in different socio-economic levels. RESULTS: In 2019, 1,977,212 (95% UI: 1,807,615-2,145,215) new cases of BC in females and 25,143 (22,231-27,786) in males was diagnosed and this major cancer caused 688,562 (635,323-739,571) deaths in females and 12,098 (10,693-13,322) deaths in males, globally. The all-age number of deaths and disability-adjusted life years attributed to BC risk factors in females had an increasing pattern, with a more prominent pattern in metabolic risks. The global estimated age-standardized QCI for BC in females in 2019 was 78.7. The estimated QCI was highest in high SDI regions (95.7). The top countries with the highest calculated QCI in 2019 were Iceland (100), Japan (99.8), and Finland (98.8), and the bottom countries were Mozambique (16.0), Somalia (8.2), and Central African Republic (5.3). The global estimated age-standardized rQCI for females was 82.2 in 2019. CONCLUSION: In spite of the partially restrained burden of BC in recent years, the attributable burden to risk factors has increased remarkably. Countries with higher SDI provided better care regarding both the condition and its responsible risk factors.

BACKGROUND AND AIM: Cirrhosis and other chronic liver diseases are complex disorders with a known burden. Currently health systems have different approaches to dealing with this issue. The objective of this study is to describe the burden attributed to and quality of care for cirrhosis and other chronic liver diseases. METHODS: Data of cirrhosis and other chronic liver diseases extracted from Global-Burden-of-Diseases 2019. Four indicators, including mortality to incidence ratio, prevalence to incidence ratio, disability-adjusted-life-years (DALYs) to prevalence ratio, and years-of-life-lost (YLLs) to years-lived-with-disability (YLDs) ratio, were defined and combined by the principal-components-analysis to construct the Quality-of-Care-Index (QCI). RESULTS: The global QCI of cirrhosis increased from 71.0 in 1990 to 79.3 in 2019. The QCI showed a favorable situation in higher SDI countries compared with lower SDI countries, with a QCI of 86.8 in high SDI countries and 60.1 in low SDI countries. The highest QCI was found in Western Pacific Region (90.2), and the lowest was for African Region (60.4). Highest QCI belonged to the 50-54 age group (99.5), and the lowest was for the 30.34 age group (70.9). Among underlying causes of cirrhosis, the highest QCI belonged to alcohol use, followed by hepatitis C and NAFLD with QCIs of 86.1, 85.3, and 81.1. CONCLUSIONS: There was a considerable variation in the QCI of cirrhosis and other chronic liver diseases. Countries with low QCI, mainly located in developing regions, need organized action to control the burden of cirrhosis and its underlying causes and improve their quality of care.

OBJECTIVE: To present estimates of prevalence and incidence of and contributors to central nervous system (CNS) cancers, death, years of life lost, years lived with disability, and disability-adjusted life years from 1990 to 2019 in North Africa and the Middle East. METHODS: Primary measures were retrieved from Global Burden of Disease 2019. Contribution of various factors to observed incidence and mortality changes was investigated with decomposition and age-period-cohort analyses. RESULTS: In 2019, 27,529 (95% uncertainty interval [UI]: 18,554-32,579; percent change compared with 1990: +152.5%) new CNS cancers and 17,773 (95% UI:12,096-20,936; percent change compared with 1990: +111.5%) deaths occurred. Meanwhile, 71.0% increase led to 71,6271 (95% UI: 493,932-848,226) disability-adjusted life years in 2019 with a halved years of life lost/years lived with disability ratio of 66.3% (proxy of worse care quality). Altogether, 97,195 (95% UI: 64,216-115,621; percent change compared with 1990: +280.5%) patients with prevalent cases were alive in 2019. All decomposed indices, including aging, cause-specific incidence, and population growth, contributed substantially to increased incidence of CNS cancers. Moreover, age brackets, study period (1990-2019), and 5-year cohorts all demonstrated positive effects, while age had a mixed influence in different age groups. Palestine harbored the highest age-standardized disability-adjusted life years rate in 2019 (232.0 [95% UI: 175.6-279.5]), while Tunisia had the lowest (41.8 [95% UI: 27.6-57.1] per 100,000). The greatest burden increase was found in Saudi Arabia (32.3%). CONCLUSIONS: The burden of CNS cancers is rising in North Africa and the Middle East, with major heterogeneities among countries. Improved early detection and health care access across countries are required to bridge inequalities and address the rising burden of CNS malignancies.

BACKGROUND: Lung cancer is one of the leading cancers, with a high burden worldwide. As a developing country, Iran is facing with population growth, widespread tobacco use, demographic and epidemiologic changes, and environmental exposures, which lead to cancers becoming a severe concern of public health in Iran. We aimed to examine the burden of lung cancer and its risk factors in Iran. METHODS: We utilized the Global Burden of Disease 2019 data and analyzed the total burden of the lung cancer and seven related risk factors by sex, age at national and sub-national levels from 1990 to 2019. RESULTS: The lung cancer age-standardized death rate increased from 11.8 (95% Uncertainty Interval: 9.7-14.4) to 12.9 (11.9-13.9) per 100,000 between 1990 and 2019. This increase was among women from 5 (4.2-7.1) to 8 (7.2-8.8) per 100,000; in contrast, there was a decline among men from 18.5 (14.8-22.6) to 17.8 (16.2-19.4) per 100,000. The burden of lung cancer is concentrated in the advanced age groups. Smoking with 53.5% of total attributable deaths (51.0%-55.9%) was the leading risk factor. At the provincial level, there was a wide range between the lowest and highest, from 8.3 (7.0-10.0) to 19.1 (16.4-22.0) per 100,000 population in the incidence rate and from 8.7 (7.3-10.3) to 20.6 (17.7-24.0) per 100,000 population in mortality rate, respectively in Tehran and West Azerbaijan provinces in 2019. CONCLUSION: The increasing trend of lung cancer burden among the entire Iranian population, the inter-provincial disparities, and the significant rise in burden of this cancer in women necessitate the urgent implementation and development of policies to prevent and manage lung cancer burden and strategies to reduce exposure to risk factors.

Background: Atherosclerotic Cardiovascular Disease (CVD) is the leading cause of death globally and dyslipidemia plays a critical role in the development of this condition. This study aimed to analyze the potential impact of socioeconomic factors on the prevalence of dyslipidemia at district level in Iran. Understanding these factors is important for development of future risk factor control programs. Methods: We used the nationwide Iran STEPwise approach to risk factor Surveillance (STEPS) 2016 survey as a representative dataset on the Non-Communicable Diseases (NCDs) risk factors in Iran. To obtain a district level dyslipidemia estimates, we utilized the small area estimation method with a Bayesian spatial hierarchical multilevel regression and multilevel mixed models. The principal component analysis was applied to derive household wealth index. For evaluation of education, successful years of schooling was calculated at district level. Urbanization ratio was defined as the proportion of residents in the urban area to the urban and rural areas for each district. Results: The highest difference was found for hypercholesterolemia coverage with 9.11 times difference among the lowest and highest prevalence across the country's district for males. Men with lower income, lower urbanization, and lower education levels had lower values of high-density lipoprotein (HDL) cholesterol, and higher level of hypercholesterolemia, and hypertriglyceridemia (P-value < 0.001). Triglyceride levels were directly correlated with all analyzed socioeconomic factors in both females and males (P-value < 0.001). Conclusion: We demonstrated that there is an inverse relationship between socioeconomic levels and dyslipidemia indices as populations with higher socioeconomic levels consistently had higher mean dyslipidemia levels. Our findings provide an excellent fundamental framework for healthcare administrators and policymakers to set goals and pursue effective preventive strategies.

RESUMO
BACKGROUND: Data on the burden of stroke and changing trends at national and subnational levels are necessary for policymakers to allocate recourses appropriately. This study presents estimates of the stroke burden from 1990 to 2019 using the results of the Global Burden of Disease (GBD) 2019 study. METHODS: For the GBD 2019, verbal autopsy and vital registration data were used to estimate stroke mortality. Cause-specific mortality served as the basis for estimating incidence, prevalence, and disability-adjusted life years (DALYs). The burden attributable to stroke risk factors was calculated by a comparative risk assessment. Decomposition analysis was applied to determine the contribution of population aging, population growth, and changes in the age-specific incidence rates. RESULTS: In 2019, the number of prevalent cases, incident cases, and deaths due to stroke in Iran were 963,512; 102,778; and 40,912, respectively. The age-standardized incidence rate (ASIR) and the age-standardized death rate (ASDR) decreased from 1990 to 2019. Of national stroke ASDRs in 2019, 44.7% (35.7-54.7%) were attributable to hypertension and 28.8% (15.2-57.4) to high fasting plasma glucose. At the subnational level, the trend of the stroke incidence and mortality rate decreased in all provinces. Stroke was responsible for 4.48% of total DALYs in 2019 (3.38% due to ischemic stroke, 0.87% due to intracerebral hemorrhage, and 0.22% due to subarachnoid hemorrhage). CONCLUSION: ASIR and ASDR of stroke are decreasing nationally and subnationally; however, the number of incident cases and deaths are increasing in all SDI quintiles, possibly due to population growth.

PURPOSE: To express a global view of care quality in major causes of mortality and morbidity in children and adolescences. METHODS: We used primary epidemiologic indicators from the Global Burden of Disease 1990-2017 database. We have created four secondary indices from six primary indices in order to assess the care quality parameters. We conducted a principal component analysis on incidence, prevalence, mortality, Years of Life Lost (YLLs), Years Lived with Disability (YLDs), and Disability Adjusted Life Years (DALYs) to create an index presented by quality-of-care index (QCI) to compare different countries. RESULTS: The global QCI scores of respiratory infection, enteric infection, leukemia, foreign body aspiration, asthma, epilepsy, diabetes mellitus, dermatitis, road injury, and neonatal disorders have improved remarkably. These causes showed equal distribution of qualified care for both sexes. The global trend of QCI score for mental health showed a steady pattern during the same time and disparities favoring females was evident. The quality of care for these causes was notably higher in developed areas. CONCLUSIONS: The global QCI revealed a universal growth in major causes of death and morbidity in <20y during 28 years. Quality of care is an associate of the level of country's development. Despite effective interventions, inequities still remain. Implementation of policies to invest in quality improvement and inequality elimination is needed.

BACKGROUND: Development of surveillance systems based on big data sources with spatial information is necessitated more than ever during this pandemic. Here, we present our pilot results of a new technique for the incorporation of spatial information of transactions and a vital registry of COVID-19 to evaluate the disease spread. METHODS: We merged two databases of laboratory-confirmed national COVID-19 registry of Iran and financial transactions of point-of-sale devices from February to March 2020 as our training data sources. Spatial information was used for the visualization of maps and movements of sick individuals. We used the point-of-sale devices-related guild to check for the dynamics of financial transactions and effectiveness of quarantines. FINDINGS: In the study period, 174,428 confirmed cases were in the COVID-19 registry with accompanying transactions information. In total, 13,924,982 financial transactions were performed by them, with a mean of 1.2 per day for each person. All guilds had a decreasing pattern of "risky" transactions except for grocery stores and pharmacies. The latter showed a decreasing pattern by impose of lockdowns. Different cities were the hotspot of disease transmission as many "high-risk" transactions were performed in them, among which Tehran (mainly its central neighborhoods) and southern cities of Lake Urmia predominated. Lockdowns indicated that the disease gradually became less transmissible. INTERPRETATION: Financial transactions can be readily used for epidemics surveillance. Semi real-time results of such iterations can be informative for policy makers, guild owners, and general population to prepare safer commuting and merchandise spaces.
RESUMO
BACKGROUND: To measure the quality of care for lip and oral cavity cancer worldwide using the data from the Global Burden of Disease (GBD) Study 2017. METHODS: After devising four main indices of quality of care for lip and oral cavity cancer using GBD 2017 study's measures, including prevalence, incidence, years of life lost, years lived with disability, and disability-adjusted life years, we utilised principal component analysis (PCA) to determine a component that bears the most proportion of info among the others. This component of the PCA was considered as the Quality-of-Care Index (QCI) for lip and oral cavity cancer. The QCI score was then reported in both men and women worldwide and different countries based on the socio-demographic index (SDI) and World Bank classifications. RESULTS: Between 1990 and 2017, care quality continuously increased globally (from 53.7 to 59.6). In 1990, QCI was higher for men (53.5 for men compared with 50.8 for women), and in 2017 QCI increased for both men and women, albeit a slightly higher rise for women (57.2 for men compared with 59.9 for women). During the same period, age-standardised QCI for lip and oral cavity cancer increased in all regions (classified by SDI and World Bank). Globally, the highest QCI scores were observed in the elderly age group, whereas the least were in the adult age group. Five countries with the least amount of QCIs were all African. In contrast, North American countries, West European countries and Australia had the highest indices. CONCLUSION: The quality of care for lip and oral cavity cancer showed a rise from 1990 to 2017, a promising outcome that supports patient-oriented and preventive treatment policies previously advised in the literature. However, not all countries enjoyed such an increase in the QCI to the same extent. This alarming finding could imply a necessary need for better access to high-quality treatments for lip and oral cavity cancer, especially in central African countries and Afghanistan. More policies with a preventive approach and paying more heed to the early diagnosis, broad insurance coverage, and effective screening programs are recommended worldwide. More focus should also be given to the adulthood age group as they had the least QCI scores globally.
