Background: Hypertension has been a significant cause of morbidity and mortality for ages. Coupled with endocrine disorders, it poses a greater risk of indisposition to the U.S population. This CDC wonder analysis explores the trends and patterns of these disorders, stratified by states and rural/urban. Methods: To attain this objective, this retrospective study has utilized data from the Center for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database to assess endocrine disorder-related mortality rates in the pediatric population from 1999 to 2011. Average Annual Percentage Change (AAPC) and Annual Percent Change (APC) were used to evaluate trends and produce age-adjusted mortality rates (AAMRs) per 100,000 people. Data was stratified by year, sex, race/ethnicity, state-wise and geographical regions. Statistical significance and confidence intervals were used to assess the reliability of the observed trends. Results: Between 1999 and 2020, 2383332 deaths in the United States were attributed to endocrine-related mortality with underlying hypertension. The Overall AAMR initially rose steeply from 10.7 in 1999 to 24.9 in 2001 (APC: 34.3; 95% CI: 9.5 to 56.7), followed by a period of further steady increase in AAMR till 36.5 in 2018 (APC: 1.6; 95% CI: 0.6 to 2.1). This progressive increase in AAMR then sharply spiked from 2018 onwards, reaching 51.7 in 2020 (APC: 18.1*; 95% CI: 9.3 to 23.5). Notable discrepancies were observed in urbanization. Non-metropolitan areas showed a higher AAMR (35.5) than metropolitan (31.5). State-level analysis revealed substantial heterogeneity, including Mississippi as the state of the highest AAMR (58.6). Conclusion: The concerning rise of AAMR in non-metropolitan areas and Mississippi calls for more targeted health-care policies. These findings underscore the need for geographically tailored public health interventions to address disparities in endocrine disorder-related mortality in these groups.

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

Background: Diabetes mellitus (DM) is a global health burden, contributing significantly to mortality and comorbidities, including chronic kidney disease (CKD), which remains a leading cause of morbidity and mortality, especially in type 1 and type 2 diabetes. Methods: This retrospective cohort study examined mortality data from the United States from the CDC WONDER database, which gathers data from death certificates. Particularly, deaths from renal problems (ICD-10 codes E10.2-E14.2) linked to diabetes were the emphasis. Sex, age, race/ethnicity, and geographic location were among the important demographic factors that were used to stratify the data for the analysis. Temporal trends were examined using linear regression, while geographic disparities were assessed through chi-square tests and regression analysis. A significance level of p<0.05 was used for all tests. Results: According to the data, the death rate from diabetes increased significantly between 1999 and 2020. Between 1999 and 2020, the number of deaths from diabetes rose from 2,325 to 74,296. From 13.12 per 100,000 in 1999 to 276.92 per 100,000 in 2020, the age-adjusted death rate increased significantly, indicating a fivefold rise in mortality rates over the 21 years. After 2010, the pace of increase became especially steep, with notable yearly increases, especially in the years after 2013. In the Hispanic population alone, the number of deaths from diabetes more than quadrupled between 2013 and 2020, rising from 5,378 in 2013 to 10,395 in 2020. Male mortality rates were consistently greater than female death rates, indicating gender-based inequities as well. By 2020, there were 41,225 male deaths from diabetes (AAMR: 351.07). Notably, the death rate for men was almost 60% greater than that for women in 2020, with rates rising more sharply for men, particularly from 2010 onward. Significant differences in diabetes-related mortality were also observed by geography. Florida, Texas, and California had the largest mortality burdens; in California alone, 73,185 deaths, or 13.8% of all deaths, occurred. Lastly, more deaths were found to occur in medical facilities, especially inpatient settings, as well as at home or in hospice care, indicating a change in the place of death. Conclusions: The study shows a significant rise in diabetes-related mortality in the US over the past two decades, with males experiencing a higher mortality rate. Geographic disparities are also evident, with Southern states and large states like California, Texas, and Florida contributing disproportionately. The shift in death places suggests increased reliance on medical facilities, home care, and hospice care. The study calls for targeted public health interventions to address the growing burden of diabetes-related mortality, particularly in high-risk regions. Presentation: Sunday, July 13, 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.

e20629 Background: Lung cancer (LC) and respiratory failure (RF) are major contributors to mortality in adults globally. Understanding long-term mortality trends across demographic, racial, geographic, and socio-economic groups is crucial to addressing disparities and improving outcomes. This study examines national mortality patterns for LC and RF in the United States from 1999 to 2023, providing critical insights into changes over time and identifying key disparities in age-adjusted mortality rates (AAMRs). Methods: A descriptive analysis of mortality data from the CDC WONDER database (1999-2023) identified deaths due to LC (ICD-10 code C34) and RF (ICD-10 code J96) in adults aged 25+. AAMRs per 100,000 population were calculated and stratified by gender, race/ethnicity, region, state, and urban-rural classification. Temporal trends were analyzed with Joinpoint regression to compute APCs and 95% CIs. Statistical significance was set at p<0.05. The study followed STROBE guidelines. Results: From 1999 to 2023, a total of 456,325 adult deaths (age 25-85+) were attributed to Lung cancer and Renal failure. Age-adjusted mortality rates (AAMRs) for lung cancer (LC) and respiratory failure (RF) decreased from 1999 to 2010 (APC = -1.2, 95% CI: -1.6 to -0.9), followed by an increase from 2010 to 2023 (APC = 1.4, 95% CI: 1.1 to 1.7). Gender trends revealed a steady decline for men, while women's Age-Adjusted Mortality Rates (AAMr) initially decreased, then increased from 2011-2023 (APC: 2.0, 95% CI: 1.7 to 2.5). Non-Hispanic White populations experienced a rapid increase in age-adjusted mortality rates from 2014 to 2017 (APC: 2.7; 95% CI: 0.9 to 3.3), while other racial/ethnic groups exhibited varied trends with declines, increases, and stabilizations. Geographically, AAMRs were highest in the Northeast (8.6; 95% CI: 8.5 to 8.7) and lowest in the Midwest (7.1; 95% CI: 7.0 to 7.1). Metropolitan areas saw declining trends until 2006, stabilizing briefly, and increasing thereafter. Non-metropolitan areas experienced notable increases post-2009 (APC = 2.3, 95% CI: 1.8 to 3.1). State-level disparities revealed Mississippi with the highest AAMR (14.0; 95% CI: 13.7 to 14.4) and Wisconsin with the lowest (3.7; 95% CI: 3.5 to 3.8). These findings highlight significant demographic, racial, and geographic variations in LC and RF mortality trends. Conclusions: LC and RF-related mortality rates initially declined from 1999 to 2010 but increased significantly from 2010 onward, with notable demographic, racial, and geographic disparities. These findings highlight the urgent need for targeted interventions and resource allocation to address these rising trends and reduce inequities across vulnerable populations.

e20520 Background: Cancer and respiratory failure (RF) are amongst leading causes of mortality in adults. This study investigates national trends in age-adjusted mortality rates (AAMRs) for cancer and RF in the United States from 1999 to 2023, focusing on disparities by gender, race, region, and rural-urban residence to inform public health strategies. Methods: This descriptive study analyzed data from the CDC WONDER database, of adults aged 25 and older. Mortality data were identified using ICD-10 codes C00–C97 (cancer) and J96 (RF). AAMRs per 100,000 population were calculated and stratified by gender, race/ethnicity, census region, urban-rural classification, and state. Temporal trends were analyzed using Joinpoint regression to estimate annual percent changes (APCs) with 95% confidence intervals (CIs). Statistical significance was set at p < 0.05. Results: From 1999 to 2023, total deaths of 1,263,368 attributed to cancer and RF (682,141 men, 581,227 women). AAMRs declined from 1999 to 2004 (APC = -1.5, 95% CI: -4.0 to -0.4), stabilized from 2004 to 2012 (APC = 0.8, 95% CI: 0.1 to 2.4), and increased from 2012 to 2023 (APC = 3.2, 95% CI: 2.9 to 3.8). Men experienced a greater initial decline (APC = -2.1, 1999–2004) but significant increases thereafter (APC = 3.0, 2012–2023), while women showed a slower decline followed by sharper increases (APC = 3.5, 2013–2023). Non-Hispanic Black populations initially declined (APC = -1.7, 1999–2003) but later increased significantly (APC = 3.0, 2014–2020). Hispanic/Latino populations declined (APC = -1.2, 1999–2009) before rising sharply (APC = 3.1, 2009–2020). American Indian or Alaska Native populations showed consistent increases (APC = 1.7, 1999–2020). Urban areas experienced initial declines (APC = -1.7, 1999–2004), followed by increases (APC = 2.4, 2011–2020). Non-metropolitan areas exhibited steeper increases (APC = 4.6, 2014–2020). Regionally, the West recorded the highest AAMR (24.0), followed by the Northeast (23.6), South (20.9), and Midwest (18.0). Mississippi had the highest state-level AAMR (36.3), while Wisconsin had the lowest (10.0). States in the top 90th percentile included Mississippi, Arkansas, and California, while Wisconsin, Minnesota, and Oregon were among the lowest. Conclusions: Cancer and RF mortality declined initially but have significantly increased in recent years. Disparities persist across gender, racial, and regional groups, underscoring the need for focused public health efforts and equitable resource distribution to address these trends.

e24020 Background: Transcatheter aortic valve replacement (TAVR) is a widely adopted treatment for severe aortic stenosis, but outcomes in cancer survivors with prior chest radiation therapy (C-XRT) remain uncertain. This study compares the clinical outcomes of TAVR between patients with a history of C-XRT and those without prior radiation exposure (control group). Methods: Patients with prior chest radiation therapy (C-XRT) were compared to a control group without radiation exposure to evaluate key clinical endpoints. For each endpoint, odds ratios (OR) and 95% confidence intervals (CI) were determined, and heterogeneity was analyzed using the I² statistic. A p-value of <0.05 was considered statistically significant. Results: Nine studies were included in the meta-analysis, encompassing 3083 C-XRT and 8891 control patients. Patients with prior C-XRT showed significantly higher long-term mortality (OR 1.84, 95% CI [1.08, 3.13], p=0.02) compared to controls. Other outcomes, including access-related vascular complications, Acute Kidney Injury, Congestive heart failure, major bleeding, need for pacemaker, short-term mortality, and stroke, did not demonstrate significant differences between the groups. Conclusions: Cancer survivors with prior chest radiation therapy undergoing TAVR may experience higher long-term mortality compared to patients without radiation exposure. However, no significant differences were observed in other major outcomes. These findings suggest that while TAVR is a viable treatment for C-XRT patients, long-term risks require further investigation to optimize patient selection and management strategies. Outcomes.

e24024 Background: Patients with active cancer undergoing trans catheter aortic valvular replacement (TAVR) face a higher risk of adverse outcomes due to the interplay between cancer and cardiovascular disease. Although TAVR is increasingly used in high-risk populations, data on outcomes for these patients remain limited. This systematic review and meta-analysis aim to evaluate the clinical outcomes associated with TAVR in patients with active cancer compared to non-cancer controls, providing insights to inform clinical decision-making in this unique group. Methods: A systematic search of major databases (PubMed, Embase, OVID, Web of Science, Scopus) was conducted to identify studies comparing clinical outcomes of TAVR between patients with active cancer and those without cancer. Key outcomes included measures of mortality, procedural complications, and post-procedure adverse events. The Mantel-Haenszel method was used for pooled analysis, applying random-effects or fixed-effects modeling based on heterogeneity assessed by Higgins I². Statistical significance was set at a p-value < 0.05. Results: Twelve studies involving 5,73,192 patients (67,684 active cancer, 505508 control) were included. Patients with active cancer undergoing TAVR have significantly higher risks of short-term mortality (OR 1.31, 95% CI [1.15, 1.49], p < 0.0001), long-term mortality (OR 2.24, 95% CI [1.85, 2.70], p < 0.0001), and major bleeding complications (OR 1.80, 95% CI [1.68, 1.92], p < 0.0001). There were no statistically significant differences in cardiovascular mortality (OR 1.33, 95% CI [0.94, 1.89], p = 0.11), myocardial infarction (OR 1.60, 95% CI [0.82, 3.11], p = 0.17), stroke (OR 0.61, 95% CI [0.28, 1.35], p = 0.22), AKI (OR 0.92, 95% CI [0.49, 1.73], p = 0.80), or the need for permanent pacemaker implantation (OR 1.12, 95% CI [0.85, 1.48], p = 0.42). Conclusions: Patients with active cancer undergoing TAVR face significantly higher risks of mortality and major bleeding compared to non-cancer controls. However, the risks of cardiovascular mortality, MI, stroke, AKI, and the need for permanent pacemaker implantation are comparable to those of non-cancer controls. Careful risk assessment and management are crucial for optimizing outcomes in this vulnerable population, and further studies are needed to refine treatment strategies. Odds ratios of all outcomes.

e18161 Background: Thyroid cancer remains a significant cause of mortality globally, with varying trends across demographic, geographic, and socioeconomic groups. Understanding these patterns is critical for developing effective prevention and intervention strategies. This study examines thyroid cancer-related mortality trends in the United States from 1999 to 2023, focusing on age-adjusted mortality rates (AAMRs) and disparities across demographic and geographic classifications. Methods: This descriptive study utilized the CDC WONDER database to extract data on thyroid cancer (ICD-10 code C73) deaths among adults aged 25 and older from 1999 to 2023. AAMRs per 1,000,000 individuals were calculated and stratified by gender, race/ethnicity, census region, urban-rural classification, and state. Temporal trends were analyzed using Joinpoint regression to compute annual percent changes (APCs) with 95% confidence intervals (CIs). Statistical significance was set at p<0.05. Results: Between 1999 and 2023, there were 55,971 deaths attributed to thyroid cancer (Men: 24,398; Women: 31,573). Overall, the AAMR increased modestly, with an APC of 1.0 (95% CI: 0.8 to 1.2). Men exhibited a slightly higher AAMR increase (APC: 1.2; 95% CI: 1.1 to 1.4) compared to women (APC: 0.9; 95% CI: 0.7 to 1.2). Racial disparities revealed varied trends. Non- Hispanic White individuals experienced a steady AAMR increase (APC: 1.0; 95% CI: 0.8 to 1.2), while Hispanic populations showed a smaller increase (APC: 0.4; 95% CI: -0.1 to 1.1). Non-Hispanic Asians or Pacific Islanders had a slight decline (APC: -0.4; 95% CI: -1.1 to 0.5), and Non-Hispanic Black populations showed segmented trends, with an APC of 0.3 (95% CI: - 7.8 to 16.7) from 1999 to 2018 and a subsequent increase (APC: 3.7; 95% CI: -5.5 to 10.5) from 2018 to 2020. Geographically, the West exhibited the highest overall AAMR (11.0; 95% CI: 10.8–11.2), followed by the Midwest (9.9; 95% CI: 9.7–10.0) and Northeast (9.8; 95% CI: 9.6–10.0), with the South reporting the lowest AAMR (9.0; 95% CI: 8.8–9.1). Hawaii had the highest state-level AAMR (12.3; 95% CI: 10.8–13.7), while Georgia recorded the lowest (7.6; 95% CI: 7.2–8.1). Urban-rural disparities indicated a slightly higher APC in non-metropolitan areas (1.0; 95% CI: 0.7–1.4) compared to metropolitan areas (0.8; 95% CI: 0.6–1.0). Conclusions: Thyroid cancer-related mortality has shown a gradual increase in the United States over the past two decades, with distinct gender, racial, and geographic disparities. Men, non-metropolitan residents, and individuals in the West and Hawaii faced higher mortality burdens. These findings underscore the importance of targeted public health strategies to address these disparities and reduce thyroid cancer mortality in vulnerable populations.
