The trend of the quality of cause-of-death data and its association with socio-economic indicators in Serbia in the period 2005-19.

This study aims to evaluate the temporal trend in the quality of cause-of-death data and garbage code profiles and to determine its association with socio-economic status in Serbia. A longitudinal study was assessed using data from mortality registers from 2005 to 2019. Computer application Analysis of Causes of National Deaths for Action (ANACONDA) calculates the distribution of garbage codes by severity and composite quality indicator: Vital Statistics Performance Index for Quality (VSPI(Q)). A relationship between VSPI(Q) and country development was estimated by analysing two socio-economic indicators: the Socio-demographic Index and the Human Development Index (HDI). Serbia indicates progress in strengthening cause-of-death statistics. The steady upward trend of the VSPI(Q) index has risen from 55.6 (medium quality) to 70.2 (high quality) over the examined years. Significant reduction of 'Insufficiently specified causes with limited impact' (Level 4) and an increase in the trend of 'High-impact garbage codes' (Levels 1 to 3) were evident. Decreased deaths of no policy value (annual percentage change of -1.41%) have manifested since 2014. A strong positive association between VSPI(Q) and socio-economic indicators was assessed, where the HDI has shown a stronger association with VSPI(Q). Improved socio-economic conditions on the national level are followed by enhanced cause-of-death data quality. Upcoming actions to improve quality should be directed at high-impact garbage codes. The study underlines the need to prioritise the education and training of physicians with a crucial role in death certification to overcome many cause-of-death quality issues identified in this assessment.

Association of human capital development and women's employment in China, 1990-2020: An empirical assessment.

This study was designed to assess the connection between human capital development and the employment of women in China from 1990 to 2020. Data was collected from the World Development Indicators, after which it was subjected to Dynamic Ordinary Least Squares and Granger causality econometric analysis. The results from the study showed that human capital development and women employment had a negative but insignificant relationship. Similarly, a unidirectional relationship existed between female employment and government capital expenditure in China, while a bidirectional association ran between women employment and government expenditure on education in the country. Therefore, it is concluded that human capital development and government expenditure on education are the strong motivating factors that drive GDP growth rate and women employment in China. Consequently, we recommend that policymakers in China should consider massive investment in human capital development in order to enhance women employment in the country. Additionally, policymakers should embark on policies and programmes that foster the expansion of China`s GDP growth rate as a measure to increase employment opportunities for women.

Cette étude a été conçue pour évaluer le lien entre le développement du capital humain et l'emploi des femmes en Chine de 1990 à 2020. Les données ont été collectées à partir des indicateurs de développement mondial, après quoi elles ont été soumises à une analyse économétrique des moindres carrés ordinaires dynamiques et de la causalité de Granger. Les résultats de l'étude ont montré que le développement du capital humain et l'emploi des femmes entretenaient une relation négative mais insignifiante. De même, il existait une relation unidirectionnelle entre l'emploi des femmes et les dépenses publiques en capital en Chine, tandis qu'une association bidirectionnelle existait entre l'emploi des femmes et les dépenses publiques d'éducation dans le pays. Par conséquent, nous concluons que le développement du capital humain et les dépenses publiques consacrées à l'éducation sont les principaux facteurs de motivation qui déterminent le taux de croissance du PIB et l'emploi des femmes en Chine. Par conséquent, nous recommandons aux décideurs politiques chinois d'envisager des investissements massifs dans le développement du capital humain afin d'améliorer l'emploi des femmes dans le pays. En outre, les décideurs politiques devraient se lancer dans des politiques et des programmes qui favorisent l'expansion du taux de croissance du PIB chinois afin d'augmenter les opportunités d'emploi pour les femmes.

Modeling multi-source plastic pollution yield and transport driven by catchment hydrometeorological processes.

Plastic pollution has emerged as a global environmental concern, impacting both terrestrial and marine ecosystems. However, understanding of plastic sources and transport mechanism at the catchment scale remains limited. This study introduces a multi-source plastic yield and transport model, which integrates catchment economic activities, climate data, and hydrological processes. Model parameters were calibrated using a combination of field observations, existing literature, and statistical random sampling techniques. The model demonstrated robust performance in simulating both plastic yield and transport from 2010 to 2020 in the upper and middle Mulan River Catchment, located in southeast China. The annual average yield coefficients were found to closely align with existing estimations, and the riverine outflow exhibited a high correlation coefficient of 0.97, with biases ranging from -63.0 % to -21.4 % across all monitoring stations. The analysis reveals that, on average, 12.5 ± 2.5 % of the total plastic yield is transported to rivers annually, with solid waste identified as the primary source, accounting for 37.8 ± 20.7 % of the total load to rivers, followed by agricultural film (26.4 ± 9.8 %), impermeable surfaces (21.5 ± 10.3 %), urban and rural sewage (10.4 ± 5.0 % and 3.0 ± 1.5 %, respectively), and industrial wastewater (0.9 ± 0.7 %). The annual average outflow was estimated to between 9.3 and 43.0 ton/year (median: 23.1) at a 95 % confidence level. This study not only provides insights into the primary sources and transport pathways of plastic pollution at the catchment scale, but also offers a valuable tool for informing effective plastic pollution mitigation strategies.

Are Doctors Equally Distributed Throughout the World?

Background: As the vital and scarce resource of the health system, physicians are responsible for treating patients and saving lives and the equitable distribution of physicians among the whole population is a prerequisite to achieving health for all. We aimed to investigate inequality in physician distribution in the world using the Gini coefficient. Methods: This descriptive-analytical study was conducted in 2021. The number of physicians and the population of countries were obtained from the WHO and United Nations (UN) databases. The Gini coefficient was calculated in three different modes and the distribution of physicians among countries in various Human Development Index (HDI) groups was determined using the physician ratio per 10,000 population. Results: There were generally more than 13 million doctors in the world. About 43% of the world's physicians were available to 20% of the world's population in very high HDI countries, and 12% of the population had access to about 1% of physicians in low HDI countries. An average of 19.5 physicians are distributed per 10,000 population worldwide. The Gini coefficient between the four groups of HDI countries was 0.55, and that of all countries in the world was 0.640. Conclusion: There was a shortage and inequality in the distribution of physicians worldwide. Governments should eliminate inequality in the distribution of the medical workforce, in particular physicians, by redoubling their efforts and accurate planning.

Global H. pylori recurrence, recrudescence, and re-infection status after successful eradication in pediatric patients: a systematic review and meta-analysis.

BACKGROUND: Little information is available regarding global H. pylori recurrence, recrudescence, and re-infection in pediatric patients after successful eradication, nor are their influencing factors clear. We conducted a systematic review and meta-analysis to determine global H. pylori recurrence status and its influencing factors in children and adolescents to improve infection management and disease prevention. METHODS: Published studies on H. pylori recurrence in children and adolescents were collected from major public databases until January 2023. H. pylori recurrences were determined using randomized-effect and fixed-effect models. Stratified analysis was performed based on various regions, countries, publication time, human development indexes (HDIs), and ages. RESULTS: A total of 3310 relevant articles were screened, and 30 articles (1915 participants) were finally enrolled for analysis. The overall H. pylori recurrence rate was 19%, and the annual recurrence rate was 13%. In stratified analysis, H. pylori annual recurrence rate in Asian children was higher than that in Europe (17% vs. 6%) and higher in developing countries than in developed countries (18% vs. 5%). In children aged ≤ 5 years, ≤ 10 years, and 11-18 years, the H. pylori recurrence rates were 30%, 14%, and 8%, respectively. H. pylori recrudescence and re-infection rates were 6% and 10%, respectively, and its recurrence was inversely correlated with HDI. CONCLUSIONS: These results provide insights into global H. pylori recurrence, annual recurrence, recrudescence, and re-infection status in pediatric population. The stratified analysis revealed the pattern and seriousness of infection, which requires further efforts to improve patient care.

Global epidemiological comparison of Streptococcus pyogenes emm-types associated with pharyngitis and pharyngeal carriage.

OBJECTIVES: To test the prevailing dogma that Streptococcus pyogenes emm-types that cause pharyngitis are the same as those associated with the carriage, using a global dataset. METHODS: Drawing on our systematic review of the global distribution of S. pyogenes emm-types and emm-clusters from 1990 to 2023, we compared the distribution and diversity of strains associated with pharyngitis and pharyngeal carriage, in the context of local United Nations Development Programme Human Development Index (HDI) values. RESULTS: We included 20 222 isolates from 71 studies done in 34 countries, with the vast majority of carriage strain data from studies in 'Low HDI' settings (550/1293; 43%). There was higher emm-type diversity for carriage than pharyngitis strains (Simpson Reciprocal Index of diversity 28.9 vs. 11.4). Compared with pharyngitis strains, carriage emm-types were disproportionately from emm-clusters E and D, usually described as 'generalist' or 'skin' strains. DISCUSSION: A limited number of studies have compared S. pyogenes strains from cases of pharyngitis compared with carriage. Our understanding of strains associated with carriage is the poorest for high-income settings. In low and medium HDI countries, we found greater strain associated with pharyngeal carriage than pharyngitis. Improving our understanding of S. pyogenes carriage epidemiology in the pre-vaccine era will help to decipher the direct and potential indirect effects of vaccines.

Confronting Inequalities and Bridging the Divide: A Retrospective Study Assessment of Country-Level COVID-19 Vaccine Equality with a Cox Regression Model.

COVID-19 vaccination is vital in reducing illness, hospitalization, and mortality in the face of this global pandemic. However, COVID-19 vaccination rates worldwide remain below WHO public health targets, and persistent structural inequities reduce vaccine uptake likelihood among populations of low socioeconomic status. We conducted a cross-sectional study based on publicly available data from the Our World in Data project. We included all 124 countries with available open epidemic data and a population of more than 5 million. We used a Cox Regression Model, with population, population density, median age, human development index, GDP per capita, gender inequality index, healthcare access and quality index, hospital beds per thousand people, completion rate of primary education, infection cases of COVID-19 by the end of 2022, and death rate due to COVID-19 by the end of 2022 as predictors for model hazard rates of completion of 50% population vaccination. According to our study, countries with higher populations, higher population density, higher human development index, lower gender inequality index, and lower hospital beds per 1000 people had a higher hazard rate, which means they were more likely to achieve 50% population vaccination faster. By utilizing the time to achieve vaccination rate goals as our primary endpoint, we evaluated inequity from a dual perspective, considering both the differences in vaccination rates and the duration required to attain them. Consequently, this study employed survival analysis approaches to gain a comprehensive understanding of vaccine drivers and population-level trends nationally and inform all communities from a statistical perspective to prepare for health emergencies. Development-level standing modified the effects of equal access to COVID-19 vaccination on cumulative cases and mortality, for which countries of low or medium human development tended to fare worse in outcomes than high human development countries. As COVID-19 vaccination efforts evolve, healthcare professionals, scholars, and policymakers need to identify the structural impediments to equitable vaccination awareness, access, and uptake so that future vaccination campaigns are not impeded by these barriers to immunization. Recognizing the complex nature of this significant barrier, it is evident that no single statistical analysis method can comprehensively address all intricacies.

Training strategies of 10,074 athletes from 121 countries based on human development index in early COVID-19 lockdown.

The aim of this study was to investigate relationships between changes in training practices and human development index (HDI) levels, and identify strategies employed by athletes who consistently maintained their training quantity during the first 100 days of the COVID-19 pandemic. A total of 10,074 athletes (5290 amateur and 4787 professional athletes from 121 countries) completed an online survey between 17 May to 5 July 2020. We explored their training practices, including specific questions on training frequency, duration and quantity before and during lockdown (March-June 2020), stratified according to the human development index (HDI): low-medium, high, or very high HDI. During the COVID-19 lockdown, athletes in low-medium HDI countries focused on innovative training. Nevertheless, women and amateur athletes experienced a substantial reduction in training activity. Performance-driven athletes and athletes from higher HDI indexed countries, were likely to have more opportunities to diversify training activities during lockdowns, facilitated by the flexibility to perform training away from home. Factors such as lockdown rules, socioeconomic environment, and training education limited training diversification and approaches, particularly in low-medium and high HDI countries. Athletes (amateurs and professionals) who maintained the quantity of training during lockdown appeared to prioritize basic cardiovascular and strength training, irrespective of HDI level. Modifying training and fitness programs may help mitigate the decrease in training activities during lockdowns. Customized training prescriptions based on gender, performance, and HDI level will assist individuals to effectively perform and maintain training activities during lockdowns, or other challenging (lockdown-like) situations.

Global disparities in surgeons' workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study.

The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI.

The Global Road Traffic Death Rate and Human Development Index from 2000 to 2019: A Trend Analysis.

BACKGROUND: Numerous studies on the association between the human development index (HDI) and road traffic death rate (RTDR) merely focus on developed countries, not reflecting the relationship between the HDI components and RTDR in a time-trend analysis. Accordingly, this study analyzes the trends of RTDR and their association with the HDI and its components from 2000 to 2019. METHODS: The RTDR data of 154 countries were imported into the unconditional latent growth model (LGM) to assess the RTDR trends. The impact of the HDI and its components (viz., education, income, and life expectancy [LE viz]) on the trajectory of RTDR was also evaluated using the conditional LGM. RESULTS: The results of the unconditional LGM indicated an overall decreasing trend in RTDR. The conditional LGM results revealed the negative effect of the HDI and its components on the model parameters. The findings of random forests indicated that education and LE were the most crucial variables. CONCLUSION: Overall, this study emphasizes the significance of HDI and its components, particularly education and LE, in lowering the number of traffic fatalities. In this sense, improving formal education and LE could be one of the main policies that policymakers could consider to reduce RTDR.

[Anaesthesia for Emergent Caesarean Section: A Population-based Study on Icelandic and Migrant Women during 2007-2018].

INTRODUCTION: General anaesthesia for emergent caesarean section, though uncommon, is vital in expediting deliveries. Studies indicate higher complication risks among pregnant migrant women. This research investigates if migrant women in Iceland are more likely to undergo general anaesthesia for emergent caesarean section compared to their Icelandic counterparts. MATERIALS AND METHODS: This population-based cohort study analysed 4,415 emergency caesarean sections in Iceland between 2007 and 2018, sourced from the National Birth Registry. Participants were categorized by citizenship, with migrants further stratified by their country's Human Development Index (HDI). NCSP-IS and ICD-10 codes indexed diseases, interventions, and complications. The impact of variables was assessed through multiple logistic regression analysis. RESULTS: Migrant women received general anaesthesia in 16.1% of cases, slightly surpassing Icelandic women's 14.6%. Adjusting for risk factors showed no increased risk for migrant women. However, they had a higher likelihood of urgent caesarean sections (OR 1.45, 95% CI 1.08-1.94, p=0.015), a known risk factor for general anaesthesia, despite fewer comorbidities. Adjusting for confounders revealed reduced odds with a history of previous caesarean section (aOR 0.73, 95% CI 0.59-0.89, p=0.003) and placement of epidural anaesthesia in the delivery room (aOR 0.49, 95% CI 0.40-0.60, p< 0.001). CONCLUSIONS: Migrant women in Iceland do not face increased risks of general anaesthesia for emergent caesarean sections. However, their elevated risk of urgent caesarean sections suggests potential challenges, including language barriers or inadequate antenatal care. Early information dissemination and targeted interventions may mitigate these risks in this vulnerable community.

Examining resilience among child protection professionals during COVID-19: A global comparison across 57 countries.

BACKGROUND: The COVID-19 pandemic led to numerous challenges for child protection professionals (CPPs). However, limited research has investigated the interwoven concepts of coping, resilience, and mental distress among CPPs during COVID-19 on a global scale. OBJECTIVES: This study aimed to explore CPPs' practice, resilience, and mental distress during COVID-19, the relationship between their resilience and mental distress, the global stability of the Multi-System Model of Resilience (MSMR), and how CPPs' resilience varied according to the Human Development Index (HDI). METHODS: Data were collected from 420 CPPs in 57 countries across five continents between July and September 2021. Participants completed an online questionnaire on demographics, resilience, mental distress, coping, and perceptions of child protection during the pandemic in their native languages. The analyses compared the countries grouped according to HDI using means comparisons, correlations, and multiple linear regressions. A two-path analysis was also performed to identify variables associated with behavioral resilience engagement and mental distress. RESULTS: The findings indicated that CPPs' perceptions of COVID-19's impact on child maltreatment varied in correlation with their country's HDI. There were also significant HDI-based differences regarding the perceived opportunity to engage in resilient behavior and its helpfulness. Years of professional experience, internal resilience, and external resilience were shown to be significant predictors of mental distress among CPPs during the pandemic, and resilience mediated how years of experience predicted mental distress. CONCLUSIONS: This study emphasized the importance of experience and internal resilience for CPPs' psychological well-being. It also provides empirical evidence to support the MSMR theory on a global scale. Additionally, it demonstrates how the perceived changes in child maltreatment during COVID-19 may be associated with regional HDI. Lastly, the opportunities CPPs had to engage in resilient behavior and how much this helped them was associated with regional HDI, but not in the way originally predicted. Study results also hold implications for how practice and policy may be altered to help CPPs cope better during times of crisis and generally.

Prevalence of postpartum depression symptoms in high-income, and low- and middle-income countries in the Covid-19 pandemic: a systematic review with meta-analysis.

OBJECTIVE: To perform a meta-analysis and comparison between high-income, and low- and middle-income countries postpartum depression symptoms prevalences. METHODS: PubMed, Embase, Virtual Health Library, Scopus, Web of Science, PsycINFO and CINAHL databases were searched until October 2022 for studies that collected data from pandemic. The metaprop command was used in the Stata statistical software v.12.0 to run a random-effects meta-analysis. RESULTS: A total of 15 studies with 4,788 postpartum women were included. The overall prevalence of postpartum depression symptoms was 31% (95% CI: 21.85-40.99). The pooled prevalence of postpartum depression symptoms among women from high-income countries [30.5% (95% CI: 16.95-46.02)] did not differ significantly from that among women from low- and middle-income countries [31.5% (95% CI: 19.26-45.15)]. However, studies that analyzed women up to one month after childbirth had a lower prevalence of postpartum depression symptoms [17.5% (95% CI: 9.85-26.62)] compared to those that observed them up to one year after childbirth [38.3% (95% CI: 33.96-42.83)]. CONCLUSIONS: The prevalence of postpartum depression symptoms was high regardless of the country's human development index and it must be regularly tracked around the world to assess, discuss, and recommend more assertive steps that may be implemented based on the particular characteristics of each country.

Oral cancer epidemiology in relation to inter-country disparities in human development in south and Southeast Asia.

OBJECTIVES: South Asia (SA) and Southeast Asia (SEA) are geographically close; however, discrepancies in oral cancer (OC) epidemiology exist between the two regions. Socioeconomic disparities may influence the OC burden. The aim of this study was to assess the epidemiology of OC and its relationship with the Inequality Adjusted Human Development Index (IHDI) and its components in SA and SEA. METHODS: Cancer data for this ecological study was obtained from GLOBOCAN 2020, while the IHDI was obtained from the Human Development Report 2020. Based on data availability, 14 SA and SEA countries were chosen. Poisson log-weighted regression models were employed to examine IHDI and its components in relation to incidence and mortality. Univariate linear regression models were utilized to determine the association between the mortality-to-incidence ratio (MIR) and the IHDI. RESULTS: Mortality and MIR of OC were negatively correlated with all sub-indices of the IHDI, including education, health and income. However, incidence and mortality of OC were influenced by region and sex. CONCLUSIONS: Higher IHDI countries tended to have lower MIR. SA and males showed higher incidence and mortality. Reducing intra-country inequalities in development may be a pragmatic approach to enhancing the OC burden and prognosis.

Population-based analysis of the human development index and risk factors for head and neck cancer.

BACKGROUND: We aimed to investigate global variations in incidence and mortality and their associations to possible risk factors for prompt cancer prevention and control. METHODS: Estimates of incidence and mortality rates for six types of head and neck cancer were extracted from the GLOBOCAN 2020 database. Summary exposure values for level-two risk factors were obtained from the Global Burden of Disease. Regression models adjusting for the human development index (HDI) were constructed to analyze correlations between age-standardized rates and risk factors. RESULTS: The incidence rates of multiple types of head and neck cancer were positively associated with HDI tiers. In addition to tobacco use and alcohol consumption, high systolic blood pressure was associated with the incidence and mortality of cancers of the salivary glands, oropharynx, hypopharynx, and larynx. Dietary risks were linked to cancers of the oropharynx, nasopharynx, and hypopharynx. CONCLUSIONS: This comprehensive analysis provides valuable insights into possible risk factors for head and neck cancer.

Changing Trends in the Global Burden of Cataract Over the Past 30 Years: Retrospective Data Analysis of the Global Burden of Disease Study 2019.

BACKGROUND: Cataracts now account for the largest proportion of the global burden of blindness and vision loss. Understanding the changing trends in the global burden of cataracts over the past 30 years and the next 15 years is of clear significance for the prevention and control of cataracts in key populations. As far as we know, research on the future burden of cataracts is lacking. OBJECTIVE: This study aims to assess the global burden of cataracts over the past 30 years by using age-period-cohort modeling and to estimate trends in the next 15 years. METHODS: Data were obtained from the Global Burden of Disease Study 2019, the United Nations Development Programme, and the WHO (World Health Organization) Global Health Observatory data repository. The assessment of trends and disparities in the number and rate of disability-adjusted life years (DALYs) for cataracts from 1990 to 2019 was conducted. The association between the age-standardized DALY rate (ASDR) and the socio-demographic index (SDI), human development index (HDI), national levels of particulate matter <2.5 µm in diameter (PM2.5), and ambient ultraviolet radiation (UVR) was determined using linear regression analysis. Additionally, we used the Nordpred (Harald Fekjær and Bjørn Møller) age-period-cohort model to predict the cataract burden from 2020 to 2034. RESULTS: Globally, the number of DALYs due to cataract increased from 3,492,604 (95% uncertainty interval [UI] 2,481,846-4,719,629) in 1990 to 6,676,281 (95% UI 4,761,210-9,006,193) in 2019. The ASDRs due to cataract decreased from 93.17 (95% UI 66.14-125.32) in 1990 to 82.94 (95% UI 59.06-111.75) in 2019, with an average annual percentage change of -0.37 (95% CI -0.44 to -0.3; P<.001). Age, female sex, air pollution, smoking, high fasting plasma glucose levels, and a high body mass index were risk factors for the burden of cataracts. SDI and HDI were negatively correlated with ASDRs of cataracts, while PM2.5 and UVR were positively associated with them. Higher DALY rates were also associated with lower SDI (R2=0.1939; P<.001), lower HDI (R2=0.2828; P<.001), national PM2.5 concentration (R2=0.1874; P<.001), and ambient UVR levels (R2=0.2354; P<.001). The prediction model suggested that the number of DALYs due to cataract will continue to rise globally, while the cataract DALY rate will continue to decrease. CONCLUSIONS: While the ASDR of cataracts has decreased, there has been a notable increase in the number of DALYs over the past 30 years. Projections suggest that the global burden of cataracts will continue to rise over the next 15 years. To address this challenge, appropriate prevention and treatment policies must be implemented.

Future directions for One Health research: Regional and sectoral gaps.

Implementation of a One Health approach varies considerably between different geographical regions and remains challenging to implement without greater inclusivity of different disciplinary capacity and expertise. We performed comparative analyses of abstracts presented at the 1st World One Health Congress (WOHC 2011) and 6th WOHC (2020) to explore and describe the evolving demographics and disciplinary scope of One Health research. We classified abstracts into six One Health research categories and twenty-three subcategories. We also recorded corresponding authors' country and regional affiliation as well as study country (i.e., the country in which the research was conducted) to explore potential asymmetries between funding recipients and study subjects. The WOHC has seen a significant expansion in participation over the last 10 years. The numbers of abstracts accepted to the Congress increased threefold over the last decade (i.e., 302 abstracts in 2010, and 932 abstracts in 2020). At both Congresses, "Disease Surveillance" accounted for the largest proportion (105/302 (35%) and 335/932 (36%) in 2010 and 2020, respectively) of all abstracts accepted. However, "Environmental and Ecological Issues" (33/302 (10%) and 94/932 (11%)), and "Sustainable Food Systems" (19/302 (6%) and 44/932 (4%)) were less well-represented categories of One Health research in both 1st and 6th WOHC respectively. In contrast, "Antimicrobial Resistance" related research increased substantially over time (4/302 (1%) in 2011) and (119/932 (13%) in 2020). There were also differences in the type of research by authors based in "Very High Human Development" index countries compared to "Medium and Low Human Development. "Public Policy" dominated the former, whereas "Disease Surveillance" dominated the latter, suggesting potential regional differences regarding One Health research priorities. The results of the study highlight potential regional gaps and differences in One Health research priorities, with respect to emphasis on operational (surveillance) versus strategic (policy) One Health activities.

An update on the global trends in the burden of primary liver cancers.

Liver cancer (LC) remains one of the major causes of cancer-related mortality worldwide. The Incidence, mortality, and prevalence associated with primary LCs were analyzed over the past decade, using GLOBOCAN 2012 and 2020, to understand the trends related to geographic and socioeconomic factors. While total cases of primary LCs continue to rise, global rates of LC incidence and mortality are slowing, mostly driven by changes seen in historically endemic regions.

Global trends in the incidence and mortality of pancreatic cancer based on geographic location, socioeconomic status, and demographic shift.

BACKGROUND: Pancreatic cancer (PC) is a lethal malignancy with a significantly rising rate of incidence and mortality. This study aims to describe the influence of geography, socioeconomic development (based on the Human Development Index [HDI]), gender, and demographic shift on the temporal trends in the global burden of PC. METHODS: Data (2020-2040) relating to the incidence, mortality of PC, and demographic shifts based on continents and HDI areas were extracted from GLOBOCAN 2020. RESULTS: PC was associated with a higher socioeconomic status. Asia contributed to the majority of the burden, led by China. Advanced age (≥65 years) contributed to the majority of the burden in all socioeconomic regions except in Medium HDI and Low HDI countries, where the younger population (<65 years) contributed more. Females contributed to a higher burden in certain countries. Future trends for 2040 showed a >60% increase in the incidence and mortality of PC with an associated demographic shift. CONCLUSION: The global burden of PC is expected to rise significantly over the next few decades regardless of geography, socioeconomic development, age, and gender. Advance knowledge of this data can help to formulate strategies and public health policies to specifically target countries and populations at risk.

Global epidemiological trends and variations in the burden of gallbladder cancer.

BACKGROUND: Gallbladder cancer (GBC) is a rare but lethal malignancy with a dismal prognosis. The aim of this study is to analyze the burdens and trends of GBC across the world based on geography, socioeconomic development (based on human development index [HDI]), and gender. METHODS: GLOBOCAN 2020 database was used to extract data (2020-2040) relating to the incidence and mortality of GBC across the world. RESULTS: Asia had the highest burden of GBC with India and China contributing to majority of the absolute burden. The burden of GBC by age standardized rate was highest in Latin America (Bolivia and Chile) and Southeast Asia (Bangladesh and Nepal). Medium HDI countries had a higher mortality rate compared to very high HDI countries. Females had a higher predilection for GBC across different regions and socioeconomic groups. GBC burden is expected to significantly increase across the world by 2040 with variable trends across different regions, age groups, and genders. CONCLUSION: The global burden of GBC will significantly increase over the next two decades with marked regional and demographic variations. The results of this study will empower national and global health leaders to develop policies to address the increasing burden of this lethal malignancy.
