It is a global health concern with regional variation in incidence and prevalence. This study aims to analyze the regional incidence and prevalence of T1DM among adolescents and young adults (15-39 years) from 1990 to 2021 in 26 regions. Methods: Global Burden of Disease (GBD) data for 2021 were analyzed to assess regional incidence and prevalence of T1DM among adolescents and young adults. The Annual Average Percentage Change (AAPC) was calculated to evaluate trends from 1990 to 2021, with statistical significance determined using p-values. Results: In 2021, middle socio-demographic index (SDI) has the highest incidence (54541) as well as prevalence (1.86 million), followed by Low-middle SDI (I: 48416, P: 1.80 million) and South Asia (I: 46310, P: 1.73 million). Oceania has the lowest incidence (356) as well as prevalence (12885), followed by Andean Latin America (I: 911, P: 31954) and Caribbean regions (I: 1214, P: 54610), respectively. The largest increase in AAPC of incidence was showed by Southern Latin America (2.23, CI: 2.11-2.30), High-income Asia Pacific (2.22, CI: 2.18-2.26), and Western Europe (1.80, CI: 1.73-1.84) regions, while Western Europe (1.72, CI: 1.66-1.75), Eastern Europe (1.64, CI: 1.63-1.66), and Australasia (1.38, CI: 1.36-1.40) showed largest increase in AAPC of prevalence. The Caribbean region had the greatest decline in AAPC of prevalence (-0.11, CI: -0.08 to -0.12) followed by Eastern Sub-Saharan Africa (-0.07, CI: -0.06 to -0.09) and Central Latin America (-0.04, CI: -0.02 to -0.07). There was no region with decline in incidence. All AAPC values were statistically significant (p < 0.000001). Conclusion: Middle SDI region exhibited the highest incidence and prevalence, highlighting the vulnerability of these populations, while Oceania and Andean Latin America bore the least burden. Notably, several regions, particularly in Europe, experienced substantial increases in both incidence and prevalence, emphasizing the need for targeted interventions. Conversely, some regions, such as the Caribbean, showed encouraging declines in prevalence, suggesting that effective prevention and control strategies can be implemented. These findings underscore the importance of tailored approaches to address the evolving burden of T1DM. Presentation: Saturday, July 12, 2025

Background: Bone density and structure-related disorders, such as osteoporosis and related fractures, significantly contribute to morbidity and mortality, particularly among aging populations. Monitoring temporal trends and geographic variations in mortality is essential to inform targeted public health interventions. In this study, we aimed to examine temporal and geographic variations in mortality associated with bone density and structure-related disorders in the United States from 1999 to 2022. Methods: Using ICD-10 codes M80-M85, this retrospective ecological study utilized mortality data extracted from the CDC WONDER database for the years 1999-2022. Age-adjusted mortality rates (AAMRs) were calculated and stratified by demographic variables (age, sex, and race/ethnicity) and geographic regions. Temporal trends were analyzed using Joinpoint regression to estimate annual percent changes (APCs). Geographic variations were visualized using choropleth maps, and subgroup analyses were performed to explore disparities. Statistical significance was set at p < 0.05. Results: Age-adjusted mortality rates (AAMRs) for bone density and structure-related disorders decreased overall from 1999 to 2019, with a subsequent rise observed in 2020 and 2022. Joinpoint regression revealed a significant negative trend from 2007-2016 (APC = -7.46%, p < 0.000001), followed by a positive reversal from 2019-2022 (APC = 3.78%, p = 0.013). Both males and females experienced declines in mortality, but females had a slightly higher APC of -3.10% compared to -2.82% for males. Asian/Pacific Islander groups exhibited the most pronounced decrease in mortality (APC = -11.92%, p < 0.000001) from 2009-2015, with a positive rebound in recent years. Black or African American populations had the smallest decline (APC = -1.35%). The Southern U.S. experienced the steepest decline in mortality from 2010-2016 (APC = -10.92%, p < 0.000001), followed by a strong positive trend from 2019-2022 (APC = 6.61%, p < 0.000001). Conversely, the West and Northeast regions showed milder trends with less pronounced reversals. Older age groups (65-74, 75-84) showed significant decreases in mortality, particularly the 65-74 group, which reversed to a positive trend (APC = 6.97%) from 2019-2022. The highest number of deaths occurred at the decedent’s home (3,330 in 2022). Subgroup analyses indicated significant temporal shifts in the mortality patterns across different racial/ethnic groups and geographic regions. Hispanic/Latino and Asian/Pacific Islander populations exhibited an increase in mortality rates post-2019, particularly in 2020. Conclusion: From 1999 to 2022, mortality from bone density and structure-related disorders in the U.S. exhibited significant temporal and geographic variations. These findings highlight the need for targeted public health strategies. Presentation: Monday, July 14, 2025

This condition causes significant morbidity, as measured by Disability-Adjusted Life Years (DALYs) and mortality rates, and its severity varies worldwide. The purpose of this study is to examine trends in T1DM-related death rates and DALYs across 26 geographical areas from 1990 to 2021 in order to provide a current picture of the disease's consequences and identify regional differences. Methods: This study examined DALYs and mortality rates per 100,000 people in individuals aged 15-39 years using data from the Global Burden of Disease Study from 1990 to 2021. Trends were assessed using the Average Annual Percentage Change (AAPC), with p-values used to define statistical significance. The study examined 26 regions with varied socioeconomic development indices (SDI). Using confidence intervals to account for data uncertainty, DALYs and mortality were examined to investigate the disease burden across time. Results: In 1990, the Middle SDI region had the highest DALYs at 298,352 (95% CI: 256,144 -349,670), which reached 382,857 (95% CI: 213,704-317,664) by 2021 (AAPC = 0.15, P-value < 0.000001). The region with the highest DALYs in 2021 was the Low-Middle SDI, with 419,772 (95% CI: 344,307- 495,496) cases (AAPC = -2.93, P-value = <0.000001). From 1990 to 2021, Oceania consistently had the lowest DALYs of 1,895 (95% CI: 1,264-2,577) and 4,210(95% CI: 3,011-5,724), respectively (AAPC= 0.15, P-value = 0.0004). Mortality rates in 1990 were highest in the Middle SDI area with 3,758 deaths (95% CI: 3,343-4,332) (AAPC= -1.23, P-value = <0.000001), but by 2021, South Asia had the highest mortality rate at 5,189(95% CI: 4,272-6,087) (AAPC= -0.49). Oceania had the lowest mortality rate of 25 deaths (95% CI 145-35) (AAPC = 0.193, P-value = <0.0004) in 1990, whereas Australasia had the lowest mortality rate of 28 deaths (95% CI 26-29) in 2021 (AAPC = -0.93, P-value = <0.000001). Conclusion: From 1990 to 2021, the global burden of type 1 diabetes—as indicated by DALYs and death rates—underwent a substantial shift, with significant rises in several regions. DALYs were highest in the Middle SDI region in 1990 but have migrated to the Low-Middle SDI region by 2021, reflecting shifting healthcare issues and demographics. Mortality rates followed a similar pattern, with South Asia and the Low-Middle SDI regions experiencing the highest rates in 2021. Over both time periods, however, Oceania and Australasia consistently had the lowest DALYs and death rates. These findings emphasise the critical need for targeted interventions in high-burden areas. Addressing these differences is crucial for decreasing the global burden of T1DM. Presentation: Sunday, July 13, 2025

Background: Hypertension is a major global health issue, affecting nearly half of U.S. adults. It is a leading risk factor for cardiovascular diseases like stroke, heart attack, and heart failure. Additionally, it is often linked to endocrine disorders, which can result in secondary hypertension. Endocrine disorders contributed to a concerning 2,383,332 deaths in the United States between 1999 and 2020, with many of these individuals having underlying hypertension. Methods: Death certificate data for adults aged 25 and older were obtained from the CDC-WONDER database. Crude mortality rates (CMR) and age-adjusted mortality rates (AAMRs) per 100,000 individuals were computed. Temporal trends were analyzed by calculating the annual percent change (APC) and the average annual percent change (AAPC) in the rates using Joinpoint regression analysis. Results: The age-adjusted mortality rate (AAMR) rose sharply from 10.7 (95% CI:10.6-10.9) in 1999 to 24.9 (95% CI: 9.5 to 56.7) in 2001, then continued to increase steadily to 36.5 (95% CI: 0.6 to 2.1) by 2018. From 2018 onwards, the rate spiked significantly, reaching 51.7 (95% CI: 9.3 to 23.5) in 2020, which coincided with the COVID-19 pandemic. Men had higher overall AAMR i.e. 36.6 as compared to women 28.4 during the span of this study. Stratifying by race, Non-Hispanic Blacks or African Americans had the highest overall age-adjusted mortality rate at 64.4 vs non-Hispanic whites, who had the lowest rate at 27.6. Southern states exhibited the highest mortality rates among the census region followed by the Western, Midwestern, and Northeastern regions. In contrast, the Annual Mortality Rates (AAMRs) displayed similar patterns across all regions. Regarding age, people aged 85 and above had the highest mortality rate among all the age groups while ages 25-34 had the lowest. Conclusion: Endocrine disorders associated with underlying hypertension showed an increasing trend throughout the study period, peaking during the COVID-19 pandemic. These findings account for immediate targeted interventions directed at the most vulnerable demographic and geographical groups Presentation: Monday, July 14, 2025

This study examines the discrepancies of paediatric endocrine abnormalities across various demographic and geographic groups in the United States, including gender, census region, race, age groups, and urbanization levels. Our objective was to identify disparities and trends to inform targeted interventions for the vulnerable demographics. Methods: Adhering to STROBES criteria, we extracted the mortality statistics due to endocrine disorders in the paediatric population from 1999-2020 from the Centre for Disease Control and Prevention-Wide Ranging Online Data for Epidemiologic research (CDC-WONDER). We calculated Age-Adjusted mortality rates (AAMRs) per 100,000 individuals. We calculated the Annual Percentage Change (APC) and Average Annual Percentage Change (AAPC) to assess trends stratified by age, gender, urbanization, race, census region, and states. Joinpoint regression model was used for analysis. Results: Between 1999 and 2020, 5161 deaths among children less than 1 year to 14 years of age in the United States were related to endocrine-related disorders. Most occurred due to thyroid disorders, diabetes mellitus, and other miscellaneous disorders related to glucose regulation and pancreatic internal secretion. The overall AAPC for endocrine-related mortality in the pediatric population increased from 1.4866 in 2008 to 2.4982 in 2020, with an AAPC of 0.1346 (95% CI: -3.1216 to -3.5003, p > 0.000001). The male population had higher AAPCs than the female population (women: -0.9938; men: 0.7223). There were notable racial differences: The Hispanic or Latino population had the highest AAPC (0.15), followed by the Black population (-0.195) and then the White population with the lowest AAPC (-0.166). According to the age group stratification, the age group with the highest AAPC was the 5-14 age group (2.03) and the lowest the less than 1 year age group, with AAPC (-2.007). There was a significant decrease in deaths in the less than 1 year age group from 1999 to 2020 (p value < 0.05) with APC (-2.0) (95% CI: -3.0191 to -0.9861) and for the 5-14 age group from 2010 to 2020 with APC (10.8861) (95% CI: 3.4843 to 18.8). Depending on the urban-rural categorization, metro areas had a higher AAPC (0.1508) compared to the non-metro areas with an AAPC (-0.4467). Conclusion: The overall decline in endocrine-related deaths in the pediatric population from 1999 to 2020 hails an improvement in efforts made to manage these disorders. However, the recent uptick in the Hispanic-Latino population emphasizes the necessity for targeted efforts to tackle these disparities and improve the health outcomes of affected communities as well as in children 1-4 years of age, depicting the increased vulnerability and need for added care in this age group.

Background: Thyroid disorders are common endocrine disorders including thyrotoxicosis, thyroiditis, hypothyroidism, and autoimmune thyroid diseases. Although it affects an estimated 200 million people globally, the epidemiology of this condition remains underexplored. Here we aimed to investigate mortality trends attributable to thyroid disorders in the US stratified by year, sex, race, and region. Methods: Using data from the CDC WONDER database, we calculated the crude and age-adjusted mortality rates (AAMRs) per 1,000,000 individuals (≥25 years) and used Joinpoint regression to determine annual and average annual percent change (AAPC) in the mortality trends. Results: Between 1999 and 2020, 561,089 deaths were recorded among patients with thyroid disorders in the United States, with an overall increasing trend in mortality (AAPC = 0.78). The age-adjusted mortality rate (AAMR) declined gradually from 1999 to 2018 (APC = -0.43, 95% CI: -0.65 to -0.22) before rising sharply from 2018 to 2020 (APC = 13.05, 95% CI: 6.39 to 20.12). Females had a higher AAMR (139.75) than males (81.99). Among racial and ethnic groups, Whites exhibited the highest AAMR (124.09), followed by American Indian or Alaskan Natives (121.36), Hispanics (89.13), Black or African Americans (88.44), and Asian or Pacific Islanders (59.36). Regional disparities showed the highest AAMR in the Midwest (130.45) and the lowest in the South (109.40). West Virginia (199.93) and North Dakota (198.82) reported the highest state-level AAMRs, while Nevada (60.18) and Florida (65.49) had the lowest. Non-metropolitan areas experienced higher mortality rates (141.04) than metropolitan areas (112.21), underscoring significant geographical and demographic variations in thyroid disorder-related mortality. Conclusion: Adults in the US have shown a rising trend in Thyroid-related deaths, with the highest mortality rates seen in females, Whites, and people living in the Midwest and Non-metropolitan areas. Our study also highlights the disparities across different demographics. Policy makers should focus on equitable access to healthcare to control this increasing mortality.

e20593 Background: Tislelizumab, an anti-PD-1 antibody, is emerging as a promising immunotherapy agent and has demonstrated clinical benefit and acceptable tolerability in recent lung cancer trials. This study aims to assess the safety and efficacy of Tislelizumab, as monotherapy or combined with chemotherapy (Group 1), as a superior treatment alternative for lung cancer compared to standard chemotherapy (Group 2) in improving patient outcomes. Methods: Following PRISMA guidelines, a systematic search was conducted through MEDLINE, Embase, Scopus, Science Direct, Cochrane (CENTRAL), and ClinicalTrials.gov from inception to December 2024 to identify Randomized Control Trials (RCTs). Hazards ratio (HRs) and risk ratios (RRs) were generated, by employing a Random-effects model with a 95% confidence interval (CI). Statistical analysis was performed using RevMan 5.4, with statistical significance set at p<0.05. Our outcomes of interest were Progression Free Survival (PFS), Overall Survival (OS), Objective Response Rate (ORR), Disease Control Rate (DCR), Duration of response (DOR), and treatment-related adverse Events. Results: A total of 6 RCTs involving 2107 patients were included for analysis. Pooled analysis demonstrated that Group 1 significantly improved PFS, OS, and DOR with HRs of 1.85 (95% CI: 1.71-1.99; p <0.00001, I² = 0%), 2.01 (95% CI: 1.75-2.29; p <0.00001, I² = 0%) and 2.14 (95% CI: 1.52-3.03; p <0.0001, I² = 39%), respectively. Group 1 has better DCR and ORR compared to Group 2 with RRs of 1.52 (95% CI: 1.12-2.07; p= 0.007, I² = 97%) and 1.50 (95% CI: 1.20-1.86; p= 0.0003, I² = 83%), respectively. The high heterogeneity observed in the pooled analysis of DCR (I² = 97%) and ORR (I² = 83%) likely reflects variability in study populations, treatment protocols, and response assessment criteria across the included RCTs. Subgroup or sensitivity analyses could help identify contributing factors. Despite the heterogeneity, the pooled effect sizes indicate a statistically significant improvement in DCR and ORR with Tislelizumab, with caution warranted when generalizing these findings. Group 1 significantly reduced all-cause mortality compared to Group 2 (RR = 0.89; 95% CI: 0.83–0.95; p = 0.0003), with no heterogeneity (I² = 0%). No significant differences were found in adverse events, except for ALT elevations. (RR = 1.36; 95% CI: 1.14–1.61; p = 0.0006, I² = 25%). Conclusions: Tislelizumab, with or without chemotherapy, demonstrates greater PFS and OS benefits compared to chemotherapy alone in patients with lung cancer. There was a significantly reduced all-cause mortality in the intervention group; however, the observed increase in the risk of ALT elevation underscores the need for vigilant liver function monitoring. When combined with chemotherapy, Tislelizumab presents a promising treatment option for lung cancer.

e16420 Background: Pancreatic cancer (PC) typically follows an indolent course and is often diagnosed at an advanced stage, contributing to its high mortality rate, particularly among older adults. Its aggressive nature makes it a significant global health burden, causing substantial mortality across nations. This analysis investigates national mortality trends in adults aged 70 years and older from 1990 to 2021, utilizing data from the Global Burden of Disease (GBD) Study. Methods: We utilized data from the GBD-Study 2021 to report the number of cases and age-standardized rates (per 100,000 population) of PC. To assess mortality trends from 1990 to 2021, we calculated the estimated annual percentage change (EAPC) along with corresponding 95%confidence intervals (CI), providing a robust evaluation of temporal patterns. Results: Over the past three decades, deaths attributable to PC have shown a significant increase globally. In 1990, the United States of America (USA) reported the highest number of PC-related deaths, followed by China and Japan. By 2021, however, China surpassed the USA, becoming the leading contributor to PC mortality, with Japan maintaining its position as the third highest.In 2021, the United Arab Emirates reported the highest mortality rate (148.15), which was more than double its 1990 rate (70.71). The Principality of Monaco (140.87) and Uruguay (129.39) held the second and third highest mortality rates, respectively. The lowest mortality rates were recorded in Mozambique (8.18), Malawi (8.98), and Sao Tome and Principe (9.01).Countries with the largest increases in the EAPC included Turkmenistan (EAPC: 15.16, 95% CI: 10.92, 21.02), Republic of Cabo Verde (EAPC: 13.60, 95% CI: 8.56, 19.48), and Mongolia (EAPC: 4.80, 95% CI: 3.11, 7.26). In contrast, the greatest declines were observed in the Republic of San Marino (EAPC: -0.32, 95% CI: -0.52, -0.07), Guam (EAPC: -0.27, 95% CI: -0.41, -0.13), and Greenland (EAPC: -0.24, 95% CI: -0.44, 0.007). Conclusions: Globally, mortality rates associated with PC among individuals aged 70 and older increased from 1990 to 2021, with particularly notable rises in Turkmenistan, Republic of Cabo Verde, and Mongolia. These findings underscore the critical need for enhanced prevention strategies, improved management, and research to address underlying disparities. Mortality percent change.

e16419 Background: Pancreatic cancer remains one of the most lethal malignancies worldwide. While high-income regions have long faced higher rates, recent trends show that lower-income regions are also beginning to see an increase. This study explores how pancreatic cancer incidence and prevalence have changed over the past 30 years among adults aged 70 and older assessing regional differences. Methods: We analyzed data from the Global Burden of Disease (GBD) spanning three decades (1990–2021) to assess pancreatic cancer incidence and prevalence rates among adults aged 70+. Data focused on different regions worldwide, grouping them by income levels using the Socio-demographic Index (SDI) and annual changes in incidence and prevalence rates were calculated. Results: In 2021, High-income Asia Pacific had the highest incidence rate at 119.52 per 100,000, whereas Low SDI regions had the lowest at 12.01 per 100,000. High-income regions accounted for the majority of cases, with over 140,000 reported, compared to fewer than 3,000 in the lowest-income areas. Andean Latin America experienced significant APC fluctuations, with a sharp rise from 2015 to 2019 followed by a decline, while High-income North America saw a recent decrease in incidence. Overall, most regions exhibit a steady increase in pancreatic cancer prevalence, with higher AAPCs in Sub-Saharan Africa, North Africa, and parts of Asia, while high-income regions show more moderate increases. Trend analysis reveals significant trends in pancreatic cancer incidence and prevalence among individuals aged 70+. Western Sub-Saharan Africa has the highest Average Annual Percent Change (AAPC) at 2.3248%, indicating the most substantial increase in prevalence from 1990 to 2021, followed by North Africa and the Middle East at 1.9906%. Low-middle SDI regions also show a steady rise with an AAPC of 1.718%, while high-income regions like High-income Asia Pacific report a notable AAPC of 1.595%. Conclusions: Our findings show a concerning rise in pancreatic cancer among older adults, with the most dramatic increases in regions like Western Sub-Saharan Africa and North Africa. To tackle this growing challenge, we need focused efforts on prevention, early detection, and accessible care, especially in lower-resource settings. Incidence percent changes.

e16418 Background: Pancreatic cancer remains one of the most fatal malignancies globally, posing a significant burden on older populations. Despite numerous reports on its prevalence, a detailed comparative analysis of national trends among adults aged 70 and older from 1990 to 2021 is scarce. This study seeks to bridge this gap by evaluating prevalence rates using data from the Global Burden of Disease (GBD) study. Methods: Prevalence data for pancreatic cancer in individuals aged 70 years and older were obtained from the GBD-2021 dataset, encompassing 204 countries and territories for the years 1990 and 2021. The Estimated Annual Percent Change (EAPC) and corresponding 95% confidence intervals (CI) were calculated to assess trends over the period from 1990 to 2021. Results: The prevalence of pancreatic cancer has shown a significant increase since 1990, reaching its highest levels in 2021. In 1990, the United States of America (USA) reported the highest prevalence, followed by Japan and China. However, by 2021, Japan ranked first in prevalence, followed by China and the USA. The analysis revealed that in 1990, the highest prevalence rates of pancreatic cancer were observed in Greenland (91.04 per 100,000), followed by Finland (82.57 per 100,000) and Japan (76.30 per 100,000). By 2021, Japan reported the highest prevalence (126.73 per 100,000), followed by Finland (119.20 per 100,000) and Canada (109.22 per 100,000). Despite the observed prevalence rates from 1990 to 2021, Turkmenistan exhibited the most significant increase (EAPC: 15.41, 95% CI: 10.91, 21.41), followed by the Republic of Cabo Verde (EAPC: 13.61, 95% CI: 8.67, 19.59) and Mongolia (EAPC: 4.81, 95% CI: 3.11, 7.20). In contrast, the most significant declines were recorded in the Republic of San Marino (EAPC: -0.308, 95% CI: -0.51, -0.03), followed by Guam (EAPC: -0.24, 95% CI: -0.37, -0.08) and Cuba (EAPC: -0.21, 95% CI: -0.33, -0.09). Conclusions: The prevalence of pancreatic cancer among adults aged 70 and older has increased significantly over the past three decades, with distinct regional patterns. Countries like Japan, China, and the USA continue to report the highest prevalence rates. These findings highlight the urgent need for targeted prevention, screening, and treatment strategies, particularly in high-burden regions, to mitigate the growing impact of pancreatic cancer in aging populations.
