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

Metastatic meningioma exhibits diverse dissemination patterns across organ systems (lungs, bone, liver, soft tissue, etc), with molecular imaging—particularly gallium 68 DOTA Tyr3-octreotide PET/CT—playing a pivotal role in detection, characterization, and guiding management.

Background Endovascular thrombectomy (EVT) has transformed acute ischemic stroke (AIS) care, with onset-to-puncture (OTP) time widely recognized as a critical determinant of outcome. However, emerging evidence suggests that in-hospital procedure time (PT)—from arterial puncture to final recanalization—may have an equally or more significant impact. This study examines the relative contribution of PT versus OTP to functional outcomes in patients with AIS undergoing EVT. Methods A retrospective analysis was conducted of 6644 patients with AIS treated at 44 international stroke centers from the Stroke Thrombectomy and Aneurysm Registry (STAR; 2016–2023). Multivariable regression, time-equivalence analysis, and marginal effects modeling were used to assess associations between PT, OTP, and 90-day modified Rankin Scale (mRS) outcomes. Centers were stratified by procedural efficiency and compared using propensity score matching (PSM). Mediation analysis evaluated whether PT accounted for inter-center differences. Results PT and OTP were independently associated with functional outcomes; however, PT had a significantly stronger effect (adjusted OR for mRS 0–2: PT=0.56 vs OTP=0.96 per hour). Each 5 min increase in PT was equivalent to 78–100 min of additional OTP in outcome impact. Centers with faster average PT had higher rates of functional independence (number needed to treat (NNT)=10), fewer complications, and lower symptomatic intracranial hemorrhage rates. PT significantly mediated the relationship between center tier and outcomes (Sobel’s P<0.001). Conclusion While minimizing OTP remains important, PT exerts a greater influence on outcomes after EVT. Procedural efficiency should be emphasized in stroke systems of care and included in center performance metrics to improve patient outcomes.

Introduction: Endovascular thrombectomy (EVT) is an effective treatment for basilar artery occlusion (BAO) stroke in select patients. While there is a growing body of literature suggesting that advanced imaging modalities such as computed tomography perfusion (CTP) and magnetic resonance (MR) may not be necessary for selecting anterior circulation large vessel occlusion stroke patients for EVT, whether advanced imaging may be superior to conventional imaging (non-contrast CT and CT angiography) in identifying good treatment candidates among BAO patients is less clear. Patients and methods: This was a multicenter retrospective cohort study of BAO EVT patients treated from 2013 to 2022 in the Stroke Thrombectomy and Aneurysm Registry. Patients selected for EVT by advanced imaging (CTP or MR) were matched with those selected by conventional imaging using propensity score matching (PSM) accounting for possible confounders. Primary outcome was functional independence at 90 days. Other outcomes include bedridden state or death at 90-days and symptomatic intracranial hemorrhage (sICH). Results: 268 patients were included. 150 patients were selected for BAO EVT by conventional imaging, 86 by CTP, and 32 by MR. Patients selected by advanced imaging were significantly older than those selected by conventional imaging (median age 71 vs 64 years, p = 0.001); patient characteristics were otherwise similar between cohorts. After PSM, 90-day outcomes were similar between the two cohorts ( p = 0.56), with similar rates of functional independence (39.4% vs 35.1%, p = 0.65), bedridden state or death (40.4% vs 44.7%, p = 0.66), and sICH (3.3% vs 5.7%, p = 0.49) for conventional and advanced imaging groups, respectively. Results were similar across treatment time windows (all p > 0.05). Conclusions: Selecting patients for basilar EVT using conventional versus advanced imaging did not result in different clinical outcomes, regardless of treatment time windows. Conventional imaging appears sufficient as a first-line tool for selecting basilar EVT patients in routine clinical practice.

ABSTRACT Histoplasmosis has a wide spectrum of presentations ranging from mild pulmonary disease to a more widespread infection leading to disseminated histoplasmosis. Gastrointestinal histoplasmosis is a rare form of disseminated histoplasmosis that most commonly causes nonspecific symptoms and rarely presents with serious symptoms. Duodenal involvement is further rare but can cause ulcerated lesions leading to upper gastrointestinal bleed. The potential for a nonspecific initial presentation quickly progressing to a fatal upper gastrointestinal bleed makes it important to keep Gastrointestinal histoplasmosis in our list of differentials, as timely initiation of appropriate antifungal therapy can significantly reduce the risk of severe complications and mortality.

Background The effectiveness of endovascular thrombectomy (EVT) for low Alberta Stroke Program Early CT score (ASPECTS) stroke patients with occlusion of the second segment of the middle cerebral artery (M2) is unclear. Methods This was a multicenter retrospective study. Patients with M1 or M2 occlusions and low ASPECTS (<6) who underwent successful EVT (modified treatment in cerebral ischemia score of 2b or higher) were included. Primary outcome was futile EVT reperfusion (defined as 90-day modified Rankin scale of 5 or 6). Other outcomes of interest include acceptable outcomes (modified Rankin scale of 3 or less) and intracranial hemorrhage (ICH), and all-cause 90-day mortality. Outcomes for M1 patients were compared to M2 patients with multivariable logistic regression models accounting for potential confounders. Results 173 patients with M1 or M2 occlusions and low ASPECTS (<6) who underwent successful EVT were identified. After multivariable adjustments, M2 patients had significantly higher odds of futile reperfusion (OR 5.48 [95%CI 1.91 to 15.7], p = 0.002), lower odds of acceptable outcomes (OR 0.33 [95%CI 0.12 to 0.89], p = 0.028), and higher odds of all-cause mortality (OR 4.90 [95%CI 1.65 to 14.5], p = 0.004). These findings suggest that EVT's efficacy for low-ASPECTS stroke patients may be diminished for patients with M2 occlusions. M2 occlusion was not significantly associated with ICH. Conclusions Among low-ASEPCTS stroke patients who underwent successful EVT, those with M2 occlusions had significantly higher odds of poor outcome compared to those with M1 occlusions.
