Leprosy in Brazil: an analysis of the Global Burden of Disease estimates between 1990 and 2019.

OBJECTIVE: To analyze the occurrence of leprosy in Brazil and its states between 1990 and 2019, according to Global Burden of Disease (GBD) estimates, and its correlation with development status. STUDY DESIGN: A descriptive and analytical ecological epidemiological study. METHODS: Rates of incidence, prevalence, and years lived with disability (YLD) due to leprosy, standardized by age, per 100,000 inhabitants, were analyzed. The trend analysis consisted of the joinpoint regression model and the average annual percentage change. The correlation between the incidence rate and the sociodemographic index (SDI) was investigated (Spearman test) at a 5% significance level. Incidence, prevalence and YLD rates were presented by country's states, sex, and age. RESULTS: There was an average percentage decrease of -1.1% per year (P < 0.001) in the incidence rate in the country and, between 1990 and 2019, a decline from 4.8 to 3.5 per 100,000 inhabitants; prevalence from 26.1 to 22.2, and YLD from 1.1 to 1.0. The incidence rate was higher among men and the elderly. Maranhão (7.0 in 1990; 4.2 in 2019), Alagoas (6.6 in 1990; 4.1 in 2019), Acre (6.1 in 1990; 4.0 in 2019), Mato Grosso (5.2 in 1990 and 3.7 in 2019), and Mato Grosso do Sul (4.8 in 1990 and 3.7 in 2019) presented the highest incidence rates. A negative correlation was observed between SDI levels and leprosy incidence rates in 1990 (R = -0.71; P < 0.0001) and 2019 (R = -0.81; P < 0.0001). CONCLUSIONS: Despite the decrease in the rates of leprosy incidence, prevalence, and YLDs over the analyzed period, Brazil has a long way towards achieving its eradication. The greater burden of the disease in males stands out. The estimated risk of the disease was higher in the states with the lowest SDI levels. Therefore, interventions must consider the heterogeneity of the disease burden geographically and between sociodemographic groups.

Characterization of clinical trials in Ecuador and their association with disease burden: Are there research gaps?

This study offers a detailed analysis of clinical trials conducted in Ecuador from 2010 to 2022 to assess alignment with the country's disease burden as indicated by the Global Burden of Disease study. Utilizing data from five registries, including ARCSA and Clinicaltrials.gov, we analyzed characteristics and coverage of 75 CTs after removing duplicates and ineligible studies. Findings reveal a 50% research gap across disease groups, with neoplasms being the only category matching disease burden. The scarcity of clinical research highlights the disparity between CTs and prevalent diseases such as cardiovascular and kidney diseases, diabetes, and other non-communicable conditions. Our results underscore the urgent need for increased clinical research investment addressing these critical health challenges in Ecuador.

Noncommunicable disease burden in Brazil and its states from 1990 to 2021, with projections for 2030.

OBJECTIVES: The aim of this study was to analyse the burden of disease due to noncommunicable diseases (NCDs) between 1990 and 2021 in Brazil. In addition, this study compared mortality from NCDs with mortality from all causes and COVID-19, analysed NCD mortality trends and projections for 2030, and analysed NCD mortality rates and risk factors attributed to these deaths among the 27 states of Brazil. STUDY DESIGN: Ecological studies. METHODS: This study used the Global Burden of Disease study (GBD) database from 1990 to 2021. Premature deaths from four NCDs (neoplasms, cardiovascular disease, chronic respiratory diseases and diabetes mellitus) were analysed. The following metrics were used to analyse the burden of NCDs in Brazil: absolute number of deaths, proportional mortality, mortality rate, years of life lost due to premature death (YLL), years lived with disabilities (YLD) and disability-adjusted years of life lost due to premature death (DALY). For comparison between the years studied and states, age-standardised rates were used. RESULTS: Finding from this study showed that there was increase in the proportion of premature deaths due to NCDs between 1990 and 2019 (29.4 % in 1990, 30.8 % in 2019), and a reduction in 2021 (24.7 %). The mortality rates, DALY and YLL from NCDs declined between 1990 and 2019 (-37.7 %, -34.5 % and -38.3 %, respectively); however, a stability in mortality rates, DALY, YLD, YLL was observed between 2019 and 2021 (-0.1 %, 0.7 %, -0.1 % and 0.8 %, respectively). Between 1990 and 2021, there was a decline in mortality rates, DALY and YLL for most states and an increase in YLD rates. However, results suggest that the Sustainable Development Goal (SDG) for the reduction in mortality from NCDs by one-third by 2030 will not be achieved. The main risk factors associated with premature death from NCDs in 2021 were high blood pressure, tobacco use, dietary risks, high body mass index (BMI) and high blood glucose levels. The correlation between sociodemographic index and percentage change in mortality rates was significant for the following total NCDs, cardiovascular disease, chronic respiratory disease, diabetes and neoplasms. CONCLUSIONS: The current study highlights the importance of deaths from NCDs in Brazil and the worsening of mortality rates since 2016, as a result of austerity measures and the COVID-19 pandemic, which compromises the achievement of the SDG reduced mortality targets for NCDs. There was a reduction in risk factors for NCDs, mainly behavioural, although metabolic risk factors are of great concern and require new strategies to promote health, prevention and comprehensive care.

Burden of disease and costs for the Unified Health System in Brazil due to diseases whose alcohol consumption is a necessary cause: an ecological study.

OBJECTIVE: This study aimed to quantify the health and economic impacts of alcohol consumption in Brazil for 2019. STUDY DESIGN: Ecological study using secondary data sources. METHODS: We calculated the disease burden using estimates from the Global Burden of Disease study, which incorporated data from health surveys and hospital records. Costs were estimated based on direct expenses recorded in the Hospital and Outpatient Information System of the Unified Health System, with data by sex, age group, cause, and Federative Units. RESULTS: Alcohol consumption was a necessary cause for 30,355 deaths and approximately 1.69 million disability-adjusted life years in Brazil, representing 2.2% and 2.6% of the national totals, respectively. The impact was more pronounced among men, in the Northeast region and within the 40- to 64-year-old age group. The total costs attributed to these outcomes reached approximately Int$43.1 million, with hospital admissions accounting for 94.16% of these expenses. CONCLUSION: In 2019, alcohol consumption had a significant impact on both the health of Brazilians and the expenses of the health system. As a preventable risk factor, alcohol consumption necessitates effective intersectoral strategies to mitigate its burden.

Global burden of young-onset Alzheimer's disease and other dementias: a secondary analysis of the global burden of disease study, 2019.

The aging of the world population has led to an increase in the epidemiology and burden of Alzheimer's disease and other dementias. Objective: To describe the global burden of young-onset Alzheimer's disease and other dementias by world region and income through a secondary analysis of the Global Burden of Disease Study 2019. Methods: This is a descriptive cross-sectional ecological study. Data by sex and five-year age groups from 40 to 64 years were extracted from the Global Burden of Disease Study results tool. We performed a descriptive analysis of prevalence, incidence, deaths, disability-adjusted life years, years of life lost, and years lived with disability. Results: In 2019, young-onset Alzheimer's disease and other dementias presented a prevalence of 2.67 cases and an incidence of 0.44 per 1,000 inhabitants globally. It carried a significant burden, resulting in 1.16 disability-adjusted life years per 1,000 inhabitants, primarily due to years of life lost, and to a lesser extent due to years lived with disability. East Asia & the Pacific, Latin America & the Caribbean, and North America are the most affected regions. Burden rates are consistently higher among women; no gradient was observed by country income. Smoking was the most relevant risk factor, presenting a broad difference by country income level. Conclusion: The global burden of young-onset Alzheimer's disease and other dementias may reshape healthcare requirements and the societal impact of dementias, and its understanding is relevant to inform decisions related to service offerings and research agendas.

O envelhecimento da população mundial tem levado a um aumento da epidemiologia e da carga da Doença de Alzheimer e outras Demências. Objetivo: Descrever a Carga Global da Doença de Alzheimer de Início Precoce e outras Demências (DAIPoD) por região do mundo e nível de renda por meio de uma análise secundária do Estudo Global de Carga de Doenças (Global Burden of Disease Study ­ GBD), 2019. Métodos: Estudo ecológico transversal descritivo. Os dados de cinco anos por sexo e faixa etária de 40 a 64 anos foram extraídos da ferramenta de resultados do GBD. Realizou-se uma análise descritiva de prevalência, incidência, óbitos, Anos de Vida Ajustados por Incapacidade (Disability Adjusted Life Years ­ DALY), Anos de Vida Perdidos (Years of Life Lost ­ YLL) e Anos Vividos com Incapacidade (Years Lived with Disability ­ YLD). Resultados: Em 2019, a DAIPoD apresentou uma prevalência de 2,67 casos e uma incidência de 0,44 casos por 1.000. Foi observada uma carga significativa, resultando em 1,16 DALY por 1.000, principalmente devido aos YLL e, em menor grau, aos YLDs. As regiões mais afetadas foram o Leste Asiático e Pacífico, a América Latina e Caribe, e a América do Norte. As taxas de carga são consistentemente mais elevadas entre as mulheres; não foi observado um gradiente por nível de renda dos países. O tabagismo foi o fator de risco mais relevante, apresentando uma ampla diferença por nível de renda do país. Conclusão: A carga global do DAIPoD pode remodelar as necessidades de saúde e o impacto social das demências, e sua compreensão é relevante para informar decisões relacionadas à oferta de serviços e agendas de pesquisa.

From across the globe - traumatic injuries are an international concern at the US-Mexico border wall.

Introduction: Socio-economic and political events of recent years have caused a significant increase in immigrants attempting to illegally cross the United States (US)-Mexico border. While a 30-foot border wall separates the US and Mexico, immigrants from around the world have used this location as their point of entry to the US. These border crossings have led to a dramatic increase in major trauma resulting in increased inpatient resource utilization and the need for comprehensive hospital services. The aim of this study was to describe the nationality of injured immigrants admitted to a Trauma Center serving a segment of the US-Mexico border wall and to report their ultimate destinations after discharge. Methods: We performed a retrospective review of patients admitted to an academic, Level 1 Trauma Center after injury at the US-Mexico border wall from 2021 to 2022. Demographic information was obtained from the trauma registry. The electronic medical record was searched to identify each patient's self-reported country of origin. Patients' nationality was then stratified by region of the world to understand geographic representation of border injury admissions. Results: We identified 597 patients injured while crossing the US-Mexico border wall representing 38 different countries. The mean age of patients was 32.2±10.4 years and 446 (75%) were male. Most patients (405, 67.8%) were Mexican, followed by 23 (3.9%) patients from Peru, 17 (2.8%) patients from India, 14 (2.3%) patients from El Salvador, 13 (2.2%) patients from Cuba and 12 (2.0%) patients from Jamaica. When considering regions of the world other than Mexico, patients were most commonly from Africa, South America and Central America. Conclusion: The increased volume of trauma associated with the US-Mexico border wall is a humanitarian and health crisis.(1) The diverse national origin of patients admitted after injury from border wall falls has shed new light on the social and interpreter services needed to care for these border injury patients and the challenges that exist in their post-discharge care.

Migraine is the most disabling neurological disease among children and adolescents, and second after stroke among adults: A call to action.

The Global Burden of Disease (GBD) study is pivotal in shaping health policies by providing comprehensive data on mortality and disability. An updated GBD2021 analysis, published in Lancet Neurology on 14 March 2024, expands the scope of neurological disorders to include 37 conditions, revealing their significant impact on global health. Neurological disorders affect 3.4 billion people, or 43.1% of the global population, making them the leading cause of disability-adjusted life years (DALYs) in 2021, with an 18.2% increase since 1990. The top three causes of DALYs in this category are stroke, neonatal encephalopathy and migraine. Migraine, affecting 1.16 billion people, ranks first among children and adolescents and second among adults aged under 60 years. Despite its substantial impact, migraine often lacks proper attention because of its non-fatal nature, invisibility and historical neglect of neurological disorders. The International Headache Society calls for recognizing migraine as a serious medical condition, promoting research and integrating migraine management into public health strategies. Effective interventions include raising awareness, improving access to treatment, adding migraine to the epidemiological surveillance agenda and exploring new treatment strategies. A coordinated effort among stakeholders is essential to alleviate the burden of migraine on individuals and society.

Performance evaluation of Mexico's health system at the national and subnational level, 1990-2019: an analysis of the Health Access and Quality Index.

OBJECTIVES: This study aimed to comprehensively evaluate Mexico's health system performance from 1990 to 2019 utilising the Health Access and Quality Index (HAQI) as a primary indicator. STUDY DESIGN: A retrospective ecological analysis was performed using data from the Global Burden of Diseases, Injuries and Risk Factors Study (GBD) study and the National Population Council (CONAPO). METHODS: HAQI values for 1990, 2000, 2010, 2015, and 2019 were examined for each state in Mexico and three age groups (young, working, and post-working). Additionally, the marginalisation index was employed to assess inequalities in the HAQI distribution across states. The concentration index of the HAQI for each year was estimated, and the efficiency of states in producing the HAQI was evaluated using a data envelopment approach. RESULTS: Through the analysis of national and subnational data, results indicated an overall improvement in healthcare access and quality during the study period. Although differences in the HAQI value related to state marginalisation decreased from 1990 to 2015, by 2019, the inequality had returned to a level comparable to 2000. Efficiency in producing health (HAQI values) exhibited substantial heterogeneity and fluctuations in the ranking order over time. States such as Nuevo León consistently performed well, while others, such as Guerrero, Chihuahua, Mexico City, and Puebla, consistently underperformed. CONCLUSIONS: The findings from this study emphasise the necessity for nuanced strategies to address healthcare disparities and enhance the overall system performance. The study provides valuable insights for ongoing discussions about the future of Mexico's healthcare system, aiming to inform evidence-based policy decisions and improve the nationwide delivery of healthcare services.

Effects of air pollution on global health: evidence from the global burden of disease study in the BRICS countries.

PURPOSE: Considering the dynamic influence of environmental, social, economic, and political factors in the emergence and growth of the BRICS countries (Brazil, Russia, India, China, and South Africa) over the years and pre-existing differences, the adverse effects of air pollution on the health and well-being of the people have remained major areas of academic inquiry and policy interventions. The present study examines the global trend of deaths and Disability Adjusted Life Years (DALYs) attributable to air pollution with particular reference to the BRICS countries for the period 1990 to 2019. METHODS: This study has used the global burden of disease estimates by using different rounds of the Global Burden of Disease (GBD) study report published by the Institute of Health Metrics Evaluation. This study has calculated the cause of death and DALYs due to environmental risk factors (i.e. Air pollution). Data analysis has been done by using the standard formula for the calculation of death (mortality) rate and DALYs rate. Similarly, we calculated the age and gender-wise death and DALYs rate by using the appropriate numerator and denominator. RESULTS: The study discovered a significant shift in disease patterns over this period, as communicable diseases like respiratory infections and tuberculosis were replaced by non-communicable diseases such as ischemic heart disease (17.2 million), chronic obstructive pulmonary disease (14.59 million), and stroke (17.02 million) as the primary causes of air pollution-related deaths in 2019 at the global level. Additionally, the study identified a worrying increase in deaths linked to neonatal disorders and respiratory infections caused by ambient particulate matter pollution in South Africa, India, and Brazil. The impact of air pollution on public health is evident across different age groups and genders, with people aged 50-69 years, those aged 70 and above, and children under 5 years being more vulnerable. Furthermore, the male population is disproportionately affected by communicable and noncommunicable diseases caused by air pollution. CONCLUSION: The study highlights the need for policymakers to implement evidence-based interventions to tackle this global health problem. The interventions should aim to reduce the emerging crisis of non-communicable diseases related to air pollution, particularly among vulnerable age groups and the male population, ultimately improving public health outcomes.

Mortality due to visceral leishmaniasis in Brazil by municipalities, 2001-2018: a spatial-temporal analysis of estimates from the Global Burden of Disease study.

OBJECTIVES: In the American regions, Brazil accounts for 97% of visceral leishmaniasis (VL) cases, with a case fatality rate of approximately 10%. This study aimed to investigate the VL mortality distribution in Brazil and identify high-priority and high-risk areas for intervention strategies. STUDY DESIGN: This was an ecological study that analysed the spatial-temporal patterns of VL mortality in Brazilian municipalities. METHODS: Age-standardised VL mortality rates from the Global Burden of Disease study from 2001 to 2018 were used. The distribution of mortality in the municipalities was assessed, and subsequently the Local Index of Spatial Autocorrelation (LISA) analysis was conducted to identify contiguous areas with high mortality rates. Scan analysis identified clusters of high spatial-temporal risks. RESULTS: The highest mortality rates and clusters were in municipalities located in the Northeast region and in the states of Tocantins and Roraima (North region), Mato Grosso do Sul (Central-West region), and Minas Gerais (Southeast region). According to LISA, there was an increase in the number of municipalities classified as high priority from the first 3-year period (n = 434) to the last 3-year period (n = 644). The spatio-temporal analysis identified 21 high-risk clusters for VL mortality. CONCLUSION: Areas with a high risk of VL mortality should prioritise preventing transmission, invest in early diagnosis and treatment, and promote the training of healthcare professionals.

Expansion of national surgical, obstetric, and anaesthesia plans in Latin America: can Brazil be next?

On the sidelines of the 75th Session of the Regional Committee of the World Health Organization for the Americas, the Republic of Ecuador hosted an event to expand on National Surgical, Obstetric, and Anaesthesia Plans (NSOAPs). NSOAPs are policy frameworks that offer governments a pathway to incorporate surgical planning into their overall health strategies. In Latin America, Ecuador became the first country to lead the development of an NSOAP and is fostering regional efforts for other Latin American countries to have sustainable surgical strengthening plans. Brazil is a prominent candidate for enrolling in an NSOAP process to enhance its public health system's functionality. An NSOAP in Brazil can help mitigate social disparities, promote greater efficiency in allocating existing resources, and optimise public health system financing. This process can also encourage the creation of resources and distinct NSOAP vocabulary in Portuguese to facilitate the development of NSOAPs in other Portuguese-speaking and low- and middle-income countries. In this viewpoint, we explore why an NSOAP can benefit Brazil's surgical system, national features that enable surgical policymaking, and how multiple stakeholder engagement can contribute to the country's planning, validation, and implementation of an NSOAP.

Burden of non-communicable diseases attributed to alcohol consumption in 2019 for the Brazilian Unified Health System.

OBJECTIVE: To estimate the health and economic burden of non-communicable diseases (NCDs) attributed to alcohol consumption in 2019 for the Brazilian Unified Health System (SUS) stratified by states. STUDY DESIGN: Observational, descriptive, and ecological study. METHODS: We used population attributable fractions (PAFs) of NCDs due to alcohol consumption from the Global Burden of Disease study. We applied the PAFs to the costs of hospitalizations and outpatient procedures of medium to high complexity paid by SUS for each outcome, obtained from official databases. We also calculated the disability-adjusted life years (DALYs) and mortality caused by alcohol-related NCDs. We converted the costs into international dollars (Int$) using the purchasing parity power in 2019. RESULTS: Alcohol-related NCDs accounted for 8.48% of deaths and 7.0% of DALYs among men, and 1.33% of deaths and 1.6% of DALYs among women. The main diseases were substance use, digestive, and neoplastic diseases. The SUS spent Int$202.0 million on alcohol-related NCDs, mostly on hospitalizations. The highest health burden was observed in the states of the Northeast region, and the highest expenses in the states from the South. The burden and cost values varied by sex, age group, and state. CONCLUSION: The study showed that alcohol consumption has a significant impact on Brazilian population morbidity and mortality and SUS expenditures, especially among men. These results can support policies for the prevention and control of alcohol consumption and health promotion at the subnational level, prioritizing strategies that are more appropriate to local realities.

Burden of disease and direct costs to the health system attributable to high body mass index in Brazil.

OBJECTIVES: Excess weight, measured by a high body mass index (BMI), is associated with the onset of many diseases, which can, in turn, lead to disability and premature death, subsequently placing a significant burden on healthcare services. This study analysed the burden of disease and the direct costs to the Brazilian Unified Health System (Sistema Único de Saúde [SUS]) attributable to high BMI in the Brazilian population. STUDY DESIGN: Ecological study. METHODS: This ecological study had two components: (1) a time-series assessment to analyse the burden of diseases attributable to high BMI from 1990 to 2019 in Brazil; and (2) a cross-sectional design to estimate the direct costs of SUS hospitalisations and outpatient procedures attributable to high BMI in 2019. Estimates from the Global Burden of Disease study and the costs of hospital admissions and outpatient procedures from the Department of Informatics of the Brazilian Unified Health System were used. Deaths, years of life lost to premature death (YLLs), years lived with disability (YLDs), and years of life lost adjusted for disability (DALYs) were analysed. The direct health cost was obtained in Brazilian Real (R$) and converted in international Dollars (INT$). RESULTS: The current study found a reduction in the number of DALYs, YLLs, and deaths per 100,000 population of cardiovascular disease (CVD) attributable to high BMI and an increase in YLD due to diabetes and cardiovascular disease attributable to high BMI from 1990 to 2019. In 2019, high BMI resulted in 2404 DALYs, 658 YLDs, 1746 YLLs, and 76 deaths per 100,000 inhabitants. In the same year, INT$377.30 million was spent on hospitalisations and high- and medium-complexity procedures to control non-communicable diseases attributable to high BMI. The states in the South and Southeast regions of Brazil presented the highest total cost per 10,000 inhabitants. CVDs and chronic kidney disease showed the highest costs per hospital admission, whereas neoplasms and CVDs presented the highest costs for outpatient procedures. CONCLUSIONS: High BMI causes significant disease burden and financial costs. The highest expenses observed were not in locations with the highest burden of disease attributable to high BMI. These findings highlight the need to improve current public policies and apply cost-effective intervention packages, focussing on equity and the promotion of healthier lifestyles to reduce overweight/obesity, especially in localities with low socioeconomic status.

Disability and costs of IHD attributable to the consumption of trans-fatty acids in Brazil.

OBJECTIVE: To estimate the disability and costs of the Brazilian Unified Health System for IHD attributable to trans-fatty acid (TFA) consumption in 2019. DESIGN: This ecological study used secondary data from the Global Burden of Disease (GBD) Study 2019 to estimate the years lived with disability from IHD attributable to TFA in Brazil in 2019. Data on direct costs (purchasing power parity: 1 Int$ = R$ 2·280) were obtained from the Hospital and Ambulatory Information Systems of the Brazilian Unified Health System. Moreover, the total costs in each state were divided by the resident population in 2019 and multiplied by 10 000 inhabitants. The relationship between the socio-demographic index, disease and economic burden was investigated. SETTING: Brazil and its twenty-seven states. PARTICIPANTS: Adults aged ≥ 25 years of both sexes. RESULTS: IHD attributable to TFA consumption resulted in 11 165 years lived with disability (95 % uncertainty interval 932­18 462) in 2019 in Brazil. A total of Int$ 54 546 227 (95 % uncertainty interval 4 505 792­85 561 810) was spent in the Brazilian Unified Health System in 2019 due to IHD attributable to TFA, with the highest costs of hospitalisations, for males and individuals aged ≥ 50 years or over. The highest costs were observed in Sergipe (Int$ 6508/10 000; 95 % uncertainty interval 576­10 265), followed by the two states from the South. Overall, as the socio-demographic index increases, expenditures increase. CONCLUSIONS: TFA consumption results in a high disease and economic IHD burden in Brazil, reinforcing the need for more effective health policies, such as industrial TFA elimination, following the international agenda.

Sustainable Development Goals' health-related indicators for Brazil and Ecuador: an analysis for the period of 1990-2019.

OBJECTIVE: This article aims to analyse the evolution of 40 Sustainable Development Goals' (SDGs) health-related indicators in Brazil and Ecuador from 1990 to 2019. STUDY DESIGN: Epidemiological study of long-term trends in 40 SDGs' health-related indicators for Brazil and Ecuador from 1990 to 2019, using estimates from the Global Burden of Disease Study. METHODS: Forty SDGs' health-related indicators and an index from 1990 to 2017 for Brazil and Ecuador, and their projections up to 2030 were extracted from the Institute for Health Metrics and Evaluation's Global Burden of Disease website and analysed. The percent annual change (PC) between 1990 and 2019 was calculated for both countries. RESULTS: Both countries have made progress on child stunting (Brazil: PC = -38%; Ecuador: PC = -43%) and child wasting prevalences (Brazil: PC = -42%; Ecuador: PC = -41%), percent of vaccine coverage (Brazil: PC = +215%; Ecuador: PC = +175%), under-5 (Brazil: PC = -75%; Ecuador: PC = -60%) and neonatal mortality rates (Brazil: PC = -69%; Ecuador: PC = -51%), health worker density per 1000 population (Brazil: PC = +153%; Ecuador: PC = +175%), reduction of neglected diseases prevalences (Brazil: PC = -40%; Ecuador: PC = -58%), tuberculosis (Brazil: PC = -27%; Ecuador: PC = -55%) and malaria incidences (Brazil: PC = -97%; Ecuador: PC = -100%), water, sanitation and hygiene mortality rates (Brazil and Ecuador: PC = -89%). However, both countries did not show sufficient improvement in maternal mortality ratio to meet SDGs targets (Brazil: PC = -37%; Ecuador: PC = -40%). Worsening of indicators were found for violence, such as non-intimate partner violence for both countries (Brazil: PC = +26%; Ecuador: PC = +18%) and suicide mortality rate for Ecuador (PC = +66%), child overweight indicator for Brazil (PC = -67%), disaster mortality rates (Brazil: PC = +100%; Ecuador: PC = +325%) and alcohol consumption (Brazil: PC = +46%; Ecuador: PC = +35%). CONCLUSIONS: Significant improvements are necessary in both countries requiring the strengthening of health and other policies, particularly concerning the prevention and management of violence and alcohol consumption, and preparedness for dealing with environmental disasters.

Economic burden for the Unified Health System attributable to excessive sodium consumption in Brazil.

OBJECTIVES: This study aimed to estimate the economic costs of excessive sodium consumption in terms of hospitalizations and outpatient procedures of medium and high complexity (OPMHC) for the Brazilian Unified Health System (SUS) and its states in 2019. STUDY DESIGN: Ecological study. METHOD: This study used population attributable fractions (PAFs) of excessive sodium consumption estimated by the Global Burden of Disease study based on the theoretical minimum risk exposure level (3 g of sodium per day), the average population consumption, and relative risks of sodium-outcome pairs. PAFs were applied to the total costs of hospitalizations and OPMHC paid by SUS for each outcome obtained from the Outpatient and Hospital Information Systems. The costs per 10,000 inhabitants in all the Brazilian states were calculated and converted into international dollars (Int$), considering the purchasing parity power in the year 2019. RESULTS: Excessive sodium consumption resulted in Int$ 98,882,386.36 (95% uncertainty interval: Int$ 3,398,343.53-312,065,319.80) in hospitalizations and OPMHC costs in Brazil in 2019. Males and the 55- to 69-year-old age group had the highest expenditures attributable to excessive sodium consumption. Cardiovascular diseases were the most significant contributors to the costs associated with the risk factor. Southern and southeastern states had the highest costs of diseases attributable to sodium. CONCLUSION: Excessive sodium consumption has a significant economic burden on SUS, particularly among men and more developed states. This underscores the inequalities in socio-economic factors and access to health services throughout the country. Economic analyses at the subnational level can provide evidence for public policy planning to define the most appropriate actions for the population's sociodemographic reality.

Mortality by avoidable causes in Brazil from 1990 to 2019: data from the Global Burden of Disease Study.

OBJECTIVES: The aim of this study was to analyse the trends of avoidable mortality in Brazil from 1990 to 2019 and its correlation with sociodemographic indexes (SDIs). STUDY DESIGN: Epidemiological mortality trends. METHODS: This study analysed data from the Global Burden of Disease database. The list of causes of avoidable death, as proposed by Nolte and McKee, was applied and included 32 causes. The current study used age-standardised mortality rates and the rates of change, in addition to a correlation analysis between avoidable death and the SDI. RESULTS: Mortality rates decreased from 343.90/100,000 inhabitants in 1990 to 155.80/100,000 inhabitants in 2019. Infectious diseases showed the largest decline in mortality rates, but notable decreases were also found for diarrhoeal diseases (-94.9%), maternal conditions (-66.5%) and neonatal conditions (-60.5%). Mortality rates for non-communicable diseases (NCDs) also decreased (-48%) but maintained a similar absolute number of deaths in 2019 compared with 1990. Decreased mortality rates were also found for ischaemic heart disease (-49.1%), stroke (-61.4%) and deaths due to adverse effects caused by medical treatments (-26.2%). Avoidable mortality rates declined in all of the 27 Brazilian states, and a high correlation was found between deaths and SDI (R = -0.74; P < 0.000001). CONCLUSIONS: A reduction in avoidable deaths was found throughout Brazil over the study period, although major regional inequalities were revealed. Richer states presented the best overall reduction in mortality rates. The biggest decreases in mortality were seen in maternal and paediatric infectious diseases in the poorest states due to the expansion of the Primary Health System and improvements in sanitation. Today, NCDs predominate and efforts should be made to formulate public policies for the prevention and control of NCDs.

The global, regional, and national burden of foreign bodies from 1990 to 2019: a systematic analysis of the global burden of disease study 2019.

BACKGROUND: Foreign bodies (FBs) are a common emergency in medical institutions, that can occur in any area and among people of any age, which are common public health problems. Understanding the epidemiological characteristics of FBs is crucial for their prevention and control. The purpose of this study was to analyze the epidemiological characteristics of FBs worldwide through the data from the Global Burden of Disease Study 2019 (GBD 2019). METHODS: We obtained data from the GBD 2019, which is an important public database to understand the disease burden of FBs. Joinpoint was used to analyze temporal trends in the incidence and death trends of FBs, which is widely used to study the long-term temporal trend of the burden of diseases. SaTScan was used to detect spatial-temporal clusters of pulmonary aspiration and foreign body in the airway (PAFBA), which is based on a Poisson model, scanning the number of people and diseases in the study area to obtain the spatial-temporal clusters of diseases. RESULTS: Globally, the age-standardized incidence rate (ASIR) and the age-standardized death rate (ASDR) of FBs in 2019 were 869.23/100,000 (679.92/100,000-1120.69/100,000) and 1.55/100,000 (1.41/100,000-1.67/100,000), respectively. The ASIR and ASDR showed downtrends with average annual percent changes (AAPCs) of -0.31% and - 1.47% from 1990 to 2019. Of note, the ASIR showed an uptrend during 2010-2019, especially in high, high-middle, and middle SDI regions. Stratified analysis by age group showed that ASIR increased in each age group in recent years. From 1990 to 2019, the ASDR in the over-70 age group showed an uptrend worldwide, especially in high and high-middle SDI regions. In different types of FBs, the ASDR of PAFBA was the highest. The death burden of PAFBA was mainly clustered in 82 countries during 1993-2007, such as Canada, Cuba, and Mexico. CONCLUSION: The most important goal is to improve public awareness and emergency knowledge of FBs through publicity methods, such as the internet or offline activities, and to improve laws and regulations. Additionally, different age groups need different targeted measures, such as strengthening the care of children, caring for elderly individuals, improving necessary monitoring programs and reporting systems, conducting effective hazard assessments, and publicity and education activities.

Expanding Global Surgery Education in Brazil: Perspectives after the 35th Brazilian Surgical Congress / Expandindo o Ensino de Cirurgia Global no Brasil: Perspectivas após o 35º Congresso Brasileiro de Cirurgia

ABSTRACT The 35th Brazilian Congress of Surgery marked a turning point for surgical education in the country. For the first time, the Brazilian College of Surgeons included Global Surgery on the main congressional agenda, providing a unique opportunity to rethink how surgical skills are taught from a public health perspective. This discussion prompts us to consider why and how Global Surgery education should be expanded in Brazil. Although Brazilian researchers and institutions have contributed to the fields expansion since 2015, Global Surgery education initiatives are still incipient in our country. Relying on successful strategies can be a starting point to promote the area among national surgical practitioners. In this editorial, we discuss potential strategies to expand Global Surgery education opportunities and propose a series of recommendations at the national level.

RESUMO O 35º Congresso Brasileiro de Cirurgia foi marcado por discussões inovadoras para a educação cirúrgica no país. Pela primeira vez, o Colégio Brasileiro de Cirurgiões incluiu a Cirurgia Global na pauta principal do congresso, proporcionando uma oportunidade única de repensar como as habilidades cirúrgicas são ensinadas a partir de uma perspectiva de saúde pública. Essa discussão nos leva a considerar por que e como o ensino da Cirurgia Global deve ser expandido no Brasil. Embora pesquisadores e instituições brasileiras tenham contribuído para a expansão do campo desde 2015, as iniciativas de educação em Cirurgia Global ainda são incipientes em nosso país. Basear-se em estratégias bem-sucedidas pode ser um ponto de partida para promover a área entre os profissionais de cirurgia nacionais. Neste editorial, discutimos potenciais estratégias para expandir as oportunidades de educação em Cirurgia Global e propomos uma série de recomendações a nível nacional.

Cuantificación de la carga de la enfermedad renal crónica en América Latina: una epidemia invisibilizada / Quantification of the burden of chronic kidney disease in Latin America: an invisible epidemic / Quantificação da carga da doença renal crônica na América Latina: uma epidemia invisível

RESUMEN Objetivo. 1) Describir la carga de la enfermedad renal crónica en países de América Latina entre 1990 y 2019 y, 2) estimar la correlación entre los años de vida saludables perdidos (AVISA) con el índice sociodemográfico y el índice de acceso y calidad de salud. Métodos. Análisis secundario y ecológico, basado en el Estudio de la Carga Global de Enfermedades, Lesiones y Factores de Riesgo 2019. Se reportaron las tasas estandarizadas de mortalidad, años perdidos por muertes prematuras (APMP), años de vida ajustados por discapacidad (AVAD) y AVISA por enfermedad renal crónica para 1990, 2005 y 2019. La información se desagregó por países, sexo, grupos etarios y subcausas. Resultados. Entre 1990 y 2019, la carga de la enfermedad renal crónica aumentó considerablemente en los países de América Latina, convirtiéndose en una de las principales causas de mortalidad y de AVISA. La tasa estandarizada de AVISA por enfermedad renal crónica se debió, en gran medida, al peso de las muertes prematuras más que a la discapacidad. En 2019, Nicaragua, El Salvador, México y Guatemala se destacaron por tener las tasas estandarizadas de mortalidad por enfermedad renal crónica y de AVISA más elevadas, mientras que Uruguay presentó las más bajas. Conclusiones. La enfermedad renal crónica es una epidemia invisibilizada que representa una carga excesiva, en mortalidad y AVISA, para los países de América Latina. Es indispensable aunar esfuerzos regionales para enfrentar la enfermedad, además de impulsar acciones locales que atiendan las particularidades de cada país.

ABSTRACT Objective. 1) Describe the burden of chronic kidney disease in Latin American countries between 1990 and 2019; and 2) Estimate the correlation between disability-adjusted life years (DALYs) and the Sociodemographic Index and the Healthcare Access and Quality Index. Methods. Secondary and ecological analysis, based on the 2019 Global Burden of Diseases, Injuries and Risk Factors Study. Standardized mortality rates, years of life lost to due to premature death (YLLs),years of healthy life lost due to disability (YLDs) and DALYs due to chronic kidney disease were reported for 1990, 2005, and 2019. Information was disaggregated by country, sex, age group, and sub-cause. Results. Between 1990 and 2019, the burden of chronic kidney disease increased considerably in Latin American countries, becoming one of the main causes of mortality and DALYs. The standardized rate of DALYs for chronic kidney disease was largely due to the weight of premature deaths rather than disability. In 2019, Nicaragua, El Salvador, Mexico, and Guatemala had the highest standardized mortality rates for chronic kidney disease and DALYs, while Uruguay had the lowest. Conclusions. Chronic kidney disease is an invisible epidemic that places an excessive burden in terms of mortality and DALYs on Latin American countries. It is essential to join forces to tackle the disease in the region, and promote local actions that address the particularities of each country.

RESUMO Objetivo. 1) Descrever a carga da doença renal crônica nos países da América Latina entre 1990 e 2019 e 2) estimar a correlação entre os anos de vida saudável perdidos (AVISA), o índice sociodemográfico e o índice de acesso e qualidade da saúde. Métodos. Análise secundária e ecológica, baseada no estudo Carga Global de Doenças, Lesões e Fatores de Risco 2019 (GBD). Foram informadas taxas de mortalidade padronizadas, anos de vida perdidos por morte prematura (AVP) por morte prematura, anos de vida ajustados por incapacidade (AVAI) e AVISA devido a doença renal crônica de 1990, 2005 e 2019. Os dados foram desagregados por país, sexo, faixas etárias e causas subjacentes. Resultados. Entre 1990 e 2019, a carga de doença renal crônica aumentou consideravelmente nos países da América Latina, tornando-se uma das principais causas de mortalidade e de AVISA. A taxa padronizada de AVISA devido à doença renal crônica foi influenciada em grande parte pelo peso das mortes prematuras, e não da incapacidade. Em 2019, Nicarágua, El Salvador, México e Guatemala se destacaram por terem as maiores taxas padronizadas de mortalidade por doença renal crônica e AVISA, ao passo que Uruguai teve as menores taxas. Conclusões. A doença renal crônica é uma epidemia invisível, que representa uma carga excessiva em termos de mortalidade e de AVISA para os países da América Latina. É essencial unir esforços na região para combater a doença, além de promover ações locais que atendam às particularidades de cada país.
