Background Patients with substance use disorder (SUD) have high rates of hospitalization, readmission, and prolonged lengths of stay. Objectives To conduct a systematic review and meta-analysis of the impact of addiction consult services in the inpatient setting for patients with SUD. Methods Five databases were systematically searched from their earliest available records through January 2025. Two authors independently screened articles, extracted data, and assessed the quality of each study with the Newcastle-Ottawa Scale for observational studies and the Cochrane risk-of-bias tool for randomized clinical trials. Pooled odds ratios (ORs) with 95% CIs were calculated for dichotomous outcomes, and mean differences were calculated for continuous outcomes. Results The search retrieved 20 studies that met inclusion criteria. The intervention for all studies was an addiction medicine consult, but the definition of this consult varied. The meta-analysis did not detect statistically significant differences in hospital length of stay, hospital readmission, or emergency department visits at 1 year among patients who received the consult compared with those who did not; however, many of these outcomes were likely underpowered. However, addiction medicine consults significantly improved the odds of inpatient initiation of medication for SUD (OR, 7.30; 95% CI, 3.30-16.13; P <.001) and postdischarge SUD treatment linkage and adherence (OR, 3.31; 95% CI, 2.06-5.32; P <.001). Conclusion Inpatient addiction consult services are associated with increased inpatient initiation of medication for SUD treatment and postdischarge treatment linkage and adherence. No clear association was identified between the consult and readmissions, emergency department utilization, or length of stay.

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 &lt; 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: The role of dissecting the right paraesophageal lymph node (RPELN) in managing papillary thyroid carcinoma (PTC) remains a subject of debate. This meta-analysis examines both established and novel risk factors associated with RPELN metastasis. Methods: Relevant studies published up to December 2024 were retrieved using PubMed, Embase, Ovid, and Scopus search engines. Data were extracted and evaluated using the Newcastle-Ottawa scale. Statistical analysis was performed using Review Manager 5.4, with heterogeneity assessed through the Q-test and I²-test. Sensitivity analysis was conducted using the leave-one-out method, and the Egger regression test was used to generate a funnel plot for publication bias assessment. Results: Out of 2,444 articles screened, 26 studies involving 16,427 patients were included in the meta-analysis. The overall RPELN metastasis rate was 12.98% (2,133/16,427). The pooled analysis revealed significant associations between RPELN metastasis and the following factors: age under 55 years (P &lt; 0.00001), male gender (P &lt; 0.00001), tumor size &gt;1 cm (P &lt; 0.00001), multifocality (P &lt; 0.00001), capsular invasion (P &lt; 0.00001), vascular invasion (P &lt; 0.00001), extra-thyroidal extension (P &lt; 0.0001), central lymph node metastasis (P &lt; 0.00001), lateral lymph node metastasis (P &lt; 0.00001), Hashimoto’s thyroiditis (P = 0.002), micro-calcifications (P = 0.01), and altered echogenicity (P = 0.03). Conversely, no significant associations were observed for tumor location in the right lobe (P = 0.07), superior pole (P = 0.08), middle pole (P = 1.00), inferior pole (P = 0.28), or tumor margins (P = 0.93) (all P &gt; 0.05). Conclusion: Factors such as age &lt;55, male sex, tumor size &gt;1 cm, multifocality, capsular invasion, vascular invasion, extra-thyroidal extension, central lymph node metastasis, lateral lymph node metastasis, and Hashimoto’s thyroiditis are significantly associated with RPELN metastasis. These should be carefully considered during RPELN dissection in PTC management. Presentation: Sunday, July 13, 2025

This study aims to examine the incidence and prevalence of T1DM by gender in the 15-39 age range between 1990 and 2021. Methods: We analyzed data from the Global Burden of Disease (GBD) to evaluate incidence and prevalence rates of T1DM in each gender from 1990 to 2021. The Annual Percentage Change (APC) and The Annual Average Percentage Change (AAPC) was used to assess trends, with p-values determining the statistical significance. Results: From 1990 to 2021, the global prevalence of T1DM was found to be increased steadily for both genders, with the highest rates recorded in 2021: 247.32 per 100,000 for females and 246.47 per 100,000 for males. Incidence rates in 2021 showed a contrasting pattern, with males exhibiting higher rates (7.18 per 100,000) compared to females (5.98 per 100,000). AAPC analysis showed that males exhibit a faster rise in both prevalence and incidence compared to females over the study period. The difference in AAPC between males and females is more pronounced for prevalence (+0.3748%) compared to incidence (+0.1956%), with all AAPC values being statistically significant (p &lt; 0.000001). Following the APC analysis, other significant trends were revealed. Male incidence experienced the greatest increase during 2015-2021, with an APC of +1.9033% (p &lt; 0.000001), whereas female incidence increased most between 2011 and 2014 (APC = +1.3050%; p &lt; 0.000001). In contrast, the most significant decline in incidence was observed in females during 1990-1992, with an APC of +0.1665% (p = 0.006799), which was the lowest increase in the dataset. For prevalence, males exhibited the highest increase during 2015-2021, with an APC of +1.3938% (p &lt; 0.000001), whereas females had their peak increase during 2006-2009, with an APC of +0.8957% (p &lt; 0.000001). The slowest increase in prevalence for females occurred during 2014-2019, with an APC of +0.4591% (p &lt; 0.000001). Conclusion: The prevalence and incidence of T1DM among people aged 15-39 increased significantly between 1990 and 2021, with a greater increase in males. This highlights the need for gender-specific strategies in T1DM prevention and management, and research into the factors driving these disparities. Presentation: Sunday, July 13, 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 &lt; 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 = &lt;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 = &lt;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 = &lt;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 = &lt;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: Type 1 diabetes mellitus (T1DM) is an autoimmune condition, characterized by the destruction of pancreatic beta cells, resulting in lifelong dependency on insulin. It is a significant health burden in adolescents and young adults, with long-term complications affecting quality of life and survival. We aim to explore sex-stratified trends in mortality and disability-adjusted life years (DALYs) due to T1DM from 1990 to 2021. Methods: We obtained sex-stratified data for adolescents and young adults (15-39 years) with T1DM from the Global Burden of Disease (GBD) from 1990 to 2021. The mortality rates were age-standardized and expressed per 100,000 deaths. Trends were analyzed as annual percentage change (APC) and average APC (AAPC) using Joinpoint Regression. Results: From 1990 to 2021, deaths due to T1DM in adolescent and young adult males increased globally from 7,123 to 9,244 per annum, with age-standardized mortality rates (ASMRs) decreasing from 0.64 to 0.61 and standardized DALYs rising from 49.56 to 51. In females, deaths rose from 6,160 to 6,892, with ASMRs declining from 0.57 to 0.47 and DALYs declining from 47.12 to 43.11. Despite the apparent rise in deaths, ASMRs exhibited a significant decline in both sexes, with an AAPC of -0.16% (95% CI: -0.20 to -0.12) in males and -0.62% (-0.68 to -0.55) in females, four times that of in males. The DALYs showed a significant decline in females with an AAPC of -0.31% (-0.35 to -0.26) but a significant increase in males with an AAPC of 0.09% (0.04 to 0.12). Males showed the greatest APC increase in ASMRs of 1.34% from 1990 to 1994, while females showed the greatest APC increase of 0.45% from 1990 to 2000, three times less and over twice the period seen in males. This was followed by the greatest APC decline of -1.14% in females from 2001 to 2011, and a non-significant decline of -0.14% till 2021. Males experienced the greatest decline of -1.14% from 2000 to 2013. It then increased significantly from 2013 to 2018 (APC: 0.73%), followed by a significant decline of -0.62% till 2021, almost four times that in females. DALYs showed a similar trend in females with the greatest increase of 0.45% from 1990 to 2000, followed by the greatest decrease of -1.14% till 2011, and then a non-significant decline of -0.14 till 2021. Males showed the greatest increase of 1.24% from 1990 to 1994 and the greatest decrease of 0.63% from 2000 to 2013, followed by a much smaller decline. Conclusion: Although ASMRs declined, the recent decline in ASMRs in females is becoming less pronounced highlighting the importance of ongoing monitoring and improvement strategies. The disparity in DALYs between males and females also demands the need for targeted interventions addressing male-specific challenges to reduce the burden of T1DM.

Background: With a global prevalence of 586,000 cases of thyroid cancer, thyroid cancer is the 10th most common malignancy. Despite advancements in early detection and treatment, the incidence of thyroid cancer continues to increase in the United States. This study aims to assess disparities in mortality trends stratified by age, sex, race, geography, urbanization status, and location of death, to guide clinical decision making. Methodology: Mortality data on thyroid cancer were extracted from the CDC-WONDER database, from 1999 to 2020. Age-adjusted mortality rates (AAMRs) and crude mortality rates (CMRs) per 100,000 were stratified by age, sex, race, geography, urbanization status, and place of death. Joinpoint regression software was used to determine annual percent change (APC) and average APC. Results: From 1999 to 2020, a total of 46,777 deaths attributed to thyroid cancer occurred in the United States, among individuals aged ≥ 25 years. The overall AAMRs showed a positive trend, increasing from 0.6 per 100,000 (95% CI: 0.5-0.6) in 1999, to 0.7 (95% CI: 0.7 - 0.7) in 2020. 56.63% of those deaths, or 26,493 deaths, occurred in women. When stratified by age group, the 85+ age group had the highest CMR of 9 (95% CI: 8.3-9.7). The racial group with the highest AAMRs were Whites, with an AAMR of 0.7 per 100,000. Mortalities in the South region accounted for 33.5% of total deaths. Moreover, metro areas also had higher mortality rates than non-metro areas. Information regarding place of death was only available for 8242 deaths, with 2763 of them occurring in medical settings. Conclusion: Mortality rates in all population groups increased from 1999 to 2020, with variations in mortality rates noted among them. Risk stratification of high-risk groups, such as older people and women, and targeted interventions are key for addressing disparities in mortality rates. Presentation: Saturday, July 12, 2025

Yet, when we examine the United States, one of the most developed nations globally, a concerning picture emerges in the realm of public health significant racial and ethnic disparities in disease outcomes. Among these, endocrine- related mortality, which includes conditions like diabetes, thyroid disorders, and hormonal imbalances, stands as a silent yet significant contributor to health inequities. Using data from the CDC WONDER database, this study seeks to explore these trends in depth, not just to identify the gaps but to shed light on the lived experiences of marginalized communities who bear the brunt of these inequities to pave the way for more equitable healthcare interventions. Methods: This descriptive study analyzes Racial and Ethnic Disparities in Endocrine-Related Mortality in the United States from 1999-2022, utilizing data from CDC Wonder database. We searched the Center for Disease Control database from 1999 to 2022 for mortality statistics with an underlying cause of death. The age-adjusted mortality rate (AAMR) was calculated per 1,000,000 deaths. We evaluated the AAMR using demographic variables such as race/ethnicity, geographic density, gender, age (25 or above), place of death, and the US Census Region. Temporal trends were assessed using Joinpoint regression software. Mortality rates by age, demographics, and place of death were examined. Statistical analysis calculated endocrine-related mortality rates and trends, with findings deemed significant at P &lt; 0. 05. Results: Between the years 1999 to 2022, 837203 deaths were recorded to be caused by endocrine-related disorders. An overall rising mortality trend from 1999-2022 among all races and ethnicities is noted, except in Asian or Pacific Islander, Black or African American, and Hispanic patients, which shows a rise till 2020 followed by fall in age-adjusted mortality rates (AAMR) in 2022. A significant dip in mortality rate was seen in 2017 in all racial and ethnic groups. American Indian or Alaska Natives showed highest AAMR (181.87, 95% CI 178.06-185.69) followed by Black or African Americans (149.78, 95% CI 148.9-150.64), Hispanic or Latinos (112.33, 95% CI 111.59-113.07), Whites (94.31, 95% CI 66.6-68.25), Asian or Pacific Islanders (67.45, 95% CI 66.6-68.25). American Indians or Alaska Natives exhibit the steepest rise over time (APC -0.32 TO 8.85) from 1999-2022. Conclusions: Mortality due to endocrine-related disorders has dramatically increased over time. Significant disparities have been noted among different races and ethnic groups, with the highest rate among Americans and the lowest among Asians. This underscores the need for targeted interventions for specific racial groups to reduce the mortality burden of endocrine-related diseases. Presentation: Sunday, July 13, 2025

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: 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.
