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: 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: Gastric cancer remains one of the leading causes of death globally and a major health concern. This study aims to analyze gastric cancer-related mortality trends over 2 decades. Methods: The CDC WONDER database was used to analyze and stratify de-identified death certificates from 1999 to 2022 across the United States. Trends in age-adjusted mortality rates (AAMR) were assessed using the Joinpoint Regression Program to determine annual percentage changes. Results: Overall, AAMR decreased from 79.26 in 1999 to 44.81 in 2022. Men and older adults had the highest AAMRs. Non-Hispanic (NH) Black or African Americans had the highest AAMR, while NH Whites had the lowest. Geographically, the Northeast had the highest AAMR, and metropolitan areas had higher AAMRs than nonmetropolitan areas. Conclusion: Gastric carcinoma has a poor prognosis, and although the general trend is decreasing across all sociodemographic areas, further research is required for targeted interventions and health policies for high-risk populations.

The treatment landscape of B-cell lymphomas has significantly evolved in recent years with approval of novel targeted therapies. CD3 × CD20 bispecific antibodies and CD19-directed monoclonal antibodies and antibody–drug conjugates have demonstrated efficacy in relapsed/refractory follicular lymphoma (FL). Bruton tyrosine kinase (BTK) inhibitor–based regimens are emerging as effective treatment options for patients with TP53-mutated classical mantle cell lymphoma (MCL). Results from ongoing clinical trials suggest that the addition of CD3 × CD20 bispecific antibodies to chemoimmunotherapy improves outcomes in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). These NCCN Guideline Insights highlight significant updates to the NCCN Guidelines for B-Cell Lymphomas for the treatment of FL, MCL, and DLBCL.

Objective Inflammatory bowel disease (IBD) is increasingly recognised in the Middle East, but limited regional data hinder a clear understanding of its burden. We aimed to examine trends in IBD diagnoses, disease phenotypes and predictors of poor outcomes at a major tertiary referral centre in the United Arab Emirates (UAE). Methods In this retrospective observational study, we evaluated diagnostic trends in a cohort of 600 Arab patients between 2002 and June 2025 and analysed detailed phenotypes in a subcohort of 414 patients diagnosed since 2012. Results We observed a nearly 13-fold increase in new IBD diagnoses among Arab patients at our centre between 2002 and 2024. This cohort (median age at diagnosis 25 years; 65% Crohn’s disease (CD; n=269), 35% ulcerative colitis (UC; n=145)) demonstrated a sharper rise in CD compared with UC, with CD being diagnosed at a significantly younger age (median 25 years vs 30 years, p=0.001). A substantial proportion of patients with CD presented with complicated disease defined as stricturing (B2; 22%, n=59), penetrating (B3; 17%, n=46) and perianal (34%, n=92) disease. Ileocolonic (L3) disease was a significant predictor for presenting with a complicated phenotype (OR 3.89). Penetrating (OR 13.9), stricturing (OR 3.38) and perianal (OR 2.22) disease were significant predictors for requiring surgery. 84% of patients with CD and 62% of patients with UC were exposed to advanced therapy. A diagnosis of CD and younger age at diagnosis were associated with a higher likelihood of needing advanced therapy. Conclusions This study provides the most comprehensive data set on IBD diagnoses and phenotypes in the UAE to date, highlighting a pronounced rise in IBD overall and of aggressive disease presentations in CD in particular.

ABSTRACTWith the global rollout of COVID‐19 vaccines, vaccine safety remains a priority. Emerging concerns have raised the potential risk of a long COVID‐like syndrome following vaccination, informally called long Vax and provisionally termed post‐COVID‐19 vaccination syndrome (PCVS). Our narrative review describes the putative manifestation, pathophysiology, and therapeutic approaches of PCVS based on the available evidence, mostly from case reports/series and observational studies. Our review noted that PCVS typically manifests within days to weeks post‐vaccination, with symptoms lasting months to years. PCVS may present as recognized diagnoses such as postural orthostatic tachycardia syndrome (POTS), small‐fibre neuropathy (SFN), myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), or as long‐term sequelae of myocarditis, vaccine‐induced thrombotic thrombocytopaenia (VITT), or immune thrombocytopaenia purpura (ITP). Symptomatically, PCVS overlaps with long COVID, such as fatigue and brain fog, but PCVS may involve more frequent paraesthesia and less dyspnoea. We also review pathophysiological hypotheses of PCVS, focussing on the vaccine‐derived spike protein and related immune responses. Finally, we discuss potential therapies used to treat patients with PCVS or related conditions, primarily documented in case reports/series, which could guide future clinical research. Overall, PCVS remains a poorly understood condition that requires more research to elucidate its prevalence, prognosis, risk factors, and treatments.

Abstract Background This study simulates how assay-specific bias influences the diagnostic performance of 0/1-h accelerated diagnostic protocols (ADPs) for 3 different high-sensitivity cardiac troponin (hs-cTn) assays. Methods We included 1493 patients presenting with chest pain. hs-cTnT (Roche Diagnostics), hs-cTnI from Abbott Diagnostics (hs-cTnI-A), and Siemens Healthineers (hs-cTnI-S) were measured at admission. The absolute total error observed in a state-of-the-art EQA study were added to the admission concentrations, producing 6 new variables being adjusted for maximum possible bias (if analytical variation is 0) (+biasmean, +biasmax95%CI, +biasmin95%CI, −biasmean, −biasmax95%CI, −biasmin95%CI). The influence of this “worst-case scenario” bias was compared after calculating sensitivity, specificity, negative and positive predictive values, and rule-out proportion for 30-day myocardial infarction or death for the observed and bias-adjusted hs-cTn concentrations. Results For 0-h rule-out, hs-cTnI-S and hs-cTnT had a sensitivity of >99.0%, compared to 97.7% for hs-cTnI-A. After adding the bias, sensitivity was unchanged for hs-cTnI-S (99.5%), but lower for hs-cTnT (95.5%), and hs-cTnI-A (96.2%). For the 0-/1-h algorithm, adding bias reduced sensitivity to 95.5% for hs-cTnT, while both hs-cTnI algorithms were unchanged (100.0%). Rule-out proportions for 0 h ranged from 0% to 60.0% for hs-cTnT, 28.2%–62.7% for hs-cTnI-A, and 3.5%–35.5% for hs-cTnI-S. For the 0-/1-h algorithm, ranges were 57.7%–75.8% (hs-cTnT), 52.8%–67.5% (hs-cTnI-A), and 45.7%–61.2% (hs-cTnI-S), Conclusion Analytical bias of hs-cTn assays affects the clinical rule-out rate of the 0/1-h ADPs more than the diagnostic sensitivity. Bias may have a greater influence on the proportion of patients requiring hospital admission and may contribute to the heterogeneity of the reported rule-out rates of current ADPs.

Importance Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with a substantial burden. Standardized global prevalence estimates and data on associated sociodemographic and risk factors are lacking. Objective To estimate the global prevalence of HS and study differences in prevalence by age, sex, geographical location, body mass index (BMI; calculated as weight in kilograms divided by height in meters squared), smoking status, gross domestic product (GDP), and Human Development Index (HDI). Data Sources and Study Selection Included studies were conducted using the standardized Global Hidradenitis Suppurativa Atlas methodology with finalized data collection before May 19, 2023. Studies were required to use a population-based sampling method and conduct clinical confirmation of HS diagnosis following a screening questionnaire. Data Extraction and Synthesis Data were independently extracted from relevant studies by 2 reviewers (D.B. and C.E.M.) using a standardized form. Extracted variables included geographic location, age, sex, BMI (median and BMI >30), smoking status, HS prevalence estimates (with 95% CIs), GDP, and HDI. A proportional meta-analysis using a random-effects model was conducted on the included studies. Main Outcomes and Measures The primary outcome was the point prevalence of HS, confirmed by clinical examination. Secondary outcomes included differences in HS prevalence by sex, age, BMI category, smoking status, and country-level socioeconomic indicators (GDP and HDI). All outcomes were prespecified before data analysis. Results The sample included 22 743 participants, identifying 247 patients with HS, across 25 studies in 23 countries spanning 6 continents. The median proportion of female patients with HS was 55.6%, and the median age was 34.5 years. While the prevalence estimates showed considerable inconsistency ( I 2 > 75%; τ 2 = 0.747), the overall random-effects global prevalence of HS was 0.99% (95% CI, 0.67%-1.46%). Female sex was the only factor observed to be associated with the prevalence estimates (β = 1.02; 95% CI, 1.01-1.03). Conclusions and Relevance In this meta-analysis, an estimated global prevalence of HS between 0.67% and 1.46% surpassed previous global estimates. Substantial global variations in HS prevalence were also observed. Female sex was the only factor associated with prevalence in this sample. Future studies assessing genetic, environmental, and etiological factors are warranted to explain the heterogeneity in prevalence.

Gastrointestinal (GI) defects pose a significant clinical challenge, impacting patient outcomes and healthcare costs. Endoscopic closure techniques have emerged as effective and minimally invasive approaches to manage these defects. This review explores the various endoscopic techniques, including over-the-scope clips (OTSC), endo suturing systems, through-the-scope (TTS) clips, and the X-Tack system. Each technique offers distinct advantages and limitations, making it suitable for specific clinical scenarios. While these devices have demonstrated promising results in clinical practice, further research is needed to optimize their use and address knowledge gaps. Large-scale randomized controlled trials are essential to establish evidence-based guidelines for device selection and procedural techniques. By embracing technological advancements and addressing research limitations, the field of endoscopic closure devices has the potential to revolutionize GI care, leading to improved patient outcomes and expanded therapeutic possibilities.

ABSTRACT Contrast‐enhanced ultrasound (CEUS) utilizes microbubble contrast agents to improve imaging clarity during surgeries, offering real‐time visualization of anatomy and perfusion without ionizing radiation. CEUS has demonstrated feasibility in congenital heart defect repairs for monitoring procedures and cerebral perfusion, in developmental dysplasia of hip surgeries for assessing hip perfusion, in neurosurgery for delineating tumor margins, and in urogenital surgeries for guiding interventions. Intraoperative CEUS improves precision, reduces reliance on postoperative imaging, and enhances safety. While it is a safe and effective tool for intraoperative decision‐making in pediatric surgeries, further studies are needed to expand its applications and standardize its use.
