Abstract Background Recent trials have furthered uncertainty regarding the endovascular benefit for medium vessel occlusions (MeVO). Stent retrievers (SR) were employed in the first attempt in most interventional arm participants. We sought to compare outcomes in acute MCA M2 occlusions between frontline aspiration and SR, and to delineate procedural and anatomical covariates associated with differential treatment effect. Methods Retrospective analysis of a multicenter stroke thrombectomy cohort identified cases of MT for M2 occlusions. Unmatched and propensity score-matched (PSM) cohorts were generated comparing frontline aspiration to standalone and combined SR. The primary outcome was functional independence (mRS 0–2) at 90 days. Recanalization, symptomatic intracranial hemorrhage (sICH), mortality, and the effect of M2 laterality, division occlusion and procedure time were assessed. Results About 1734 patients with M2 occlusions underwent either frontline aspiration (n = 711) or SR/combined (n = 958) thrombectomy between 2013 and 2024. PSM analysis favored aspiration for functional independence (49.9% vs 44.0%, OR 1.27 (1.03–1.57)), complete recanalization (61.2% vs 48.7%, OR 1.66 (1.34–2.05)), complete first pass effect (35.0% vs 27.6%, OR 1.42 (1.13–1.78)), and sICH (3.5% vs 6.2%, OR 0.55 (0.33–0.91)), with no difference in mortality. Frontline aspiration had significantly shorter procedural times (median 28 [IQR 15–49.5] vs 51 [IQR 35–78] minutes; p < 0.001). For every minute increase in procedure time, the probability of functional independence decreased significantly (p < 0.001) less with frontline aspiration (0.35%) compared to SR/combined (1.61%). Conclusion Frontline aspiration for M2 occlusions resulted in better clinical and angiographic outcomes compared to SRs. Future trials for MeVO with a focus on contact aspiration thrombectomy may succeed where recent trials have failed.

Background A substantial proportion of patients with chronic rhinosinusitis (CRS) remain partly controlled or uncontrolled despite endoscopic sinus surgery (ESS) and maximal medical therapy. For these difficult-to-treat cases, topical antibiotic irrigations have been proposed as an adjunctive therapy, particularly when delivered via large-volume, low-pressure systems that enhance sinus penetration post-ESS. Evidence on their efficacy and prescribing patterns in this population remains limited. Objective This study aims to evaluate the use and outcomes of topical antibiotic irrigations in patients with difficult-to-treat CRS. Methods A retrospective, multi-site cohort study was conducted across tertiary academic medical centers. Adult patients with persistent CRS symptoms despite bilateral full-house ESS and conventional postoperative medical management were included. Patients with cystic fibrosis or granulomatosis with polyangiitis were excluded. Demographic, clinical, and treatment data were collected. Primary outcomes were infection resolution at 8 weeks and changes in Sino-Nasal Outcome Test-22 (SNOT-22) scores. Results Sixty-seven patients met inclusion criteria. Mupirocin (41.8%), tobramycin (23.9%), and gentamicin (17.9%) were the most commonly prescribed agents. After 8 weeks, 62.7% of patients achieved infection clearance. Among 44 patients with SNOT-22 data, scores improved significantly from 34.8 ± 20.2 to 21.8 ± 14.7 ( P < .001). Improvement in SNOT-22 scores was more pronounced in patients who cleared the infection compared to those who did not. Conclusion Large-volume topical antibiotic irrigations were associated with high infection resolution rates and clinically meaningful SNOT-22 improvements in patients with difficult-to-treat CRS. These findings support their potential utility as an adjunctive therapy in select postsurgical patients and warrant further prospective investigation.

Objectives To comprehensively review the available literature on prehabilitation and rehabilitation exercise, nutrition, and psychological support interventions for patients with kidney cancer (KC), to summarise the clinically relevant efficacy and cost‐effectiveness of interventions, to expose key knowledge gaps, and to inform future investigations and initiatives. Methods This review was performed according to the per Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) Extension for Scoping Reviews Guidelines. We included randomised controlled trials (RCTs) assessing programmes of prehabilitation or rehabilitation, exercise, psychological support, or nutrition components in patients with KC or KC caregivers from January 2004 to March 2022. Statistically significant positive (SS+) and negative (SS−) results were summarised. Results The systematic search yielded 10 968 records including 18 RCTs, involving 2774 unique subjects, 706 of whom were KC patients/survivors. None included caregivers or assessed cost‐effectiveness. Two interventions were implemented before surgery, one was implemented prior to initiation of systemic therapy, eight were implemented during systemic or radiation therapy, three were implemented after treatment, while implementation time was not specified for four interventions. Conclusion Most (14/18) RCTs involving exercise, nutrition, psychological support, or prehabilitative or rehabilitative programmes for KC performed to date demonstrated SS+ results. The evidence was most robust regarding previously evaluated psychological support, especially mindfulness‐based interventions (9/10 studies demonstrating SS+ improvement in primary outcomes), followed by therapeutically valid exercise with/without psychological support (5/8 RCTs demonstrated efficacy), then nutrition or pharmacological interventions (2/5 demonstrated efficacy). Level 1 evidence supports counselling patients and referral to mindfulness‐based psychological therapy along with physical therapy or physical medicine and rehabilitation, as well as consideration of preoperative carbohydrate drinks. No studies have examined impact on caregivers, or cost‐effectiveness, which are both critical areas for future study.

Abstract Background Measurement of cardiac troponin (cTn) using high-sensitivity assays is recommended for the diagnosis of myocardial infarction. We determined sex-specific and uniform 99th percentile upper reference limits (URLs) using the new Elecsys® Troponin T high-sensitivity Gen 6 assay in a global, healthy reference range cohort. Methods Lithium-heparin plasma and serum samples were prospectively collected from apparently healthy individuals aged ≥20 years across 34 global sites in the United States, Europe, China, and Japan. cTnT was measured using the Troponin T high-sensitivity Gen 6 assay on the Cobas® e 801 analyzer. Exclusion criteria were defined according to the 2022 IFCC guidance. Uniform and sex-specific 99th percentile URLs and nonparametric 95% CIs were determined in plasma and serum separately and combined. Results The final study population comprised 4147 participants (52.5% female) with a median (25th–75th percentiles) age of 48.0 (33.0–59.0) years; 45.8%, 47.9%, 5.2%, and 1.1% were White, Asian, Black, and other/unknown, respectively. For sample matrices combined (n = 8294), 81.0% and 99.2% of cTnT values were above the limit of detection in females and males, respectively. Sex-specific 99th percentile URLs (95% CI) were 18 (16–23) ng/L for females and 32 (28–35) ng/L for males; the uniform 99th percentile URL was 27 (24–31) ng/L. URLs were comparable in plasma and serum samples. Conclusions This study determined sex-specific and uniform 99th percentile URLs for the Troponin T high-sensitivity Gen 6 assay that were comparable irrespective of the matrix used in a large, global, healthy reference population.

Abstract Background Intracranial mesenchymal tumors, FET::CREB fusion-positive (ICMT), show fusions involving FET RNA-binding protein family genes (EWSR1 or FUS) and CREB family of transcription factors (ATF1, CREB1, or CREM). The methylation signature(s), gene expression characteristics, and clinical behavior of this important tumor type require further characterization. Methods We study the methylation profiles of 81 ICMT cases (61 newly profiled cases and 20 cases from publicly available sources). Clinicopathologic and genomic data were recorded for each case when available. Results ICMT showed a relatively distinct methylation signature compared to related tumors. Among the 65 cases where fusion types were documented, the identified fusions included EWSR1::ATF1 (25 cases), EWSR1::CREB1 (12 cases), EWSR1::CREM (21 cases), FUS::CREM (3 cases), and SMARCA2::CREM (4 cases). We confirmed the prior description of 2 distinct subgroups of ICMT (subclasses A and B). The majority of the cases belonged to subclass A (n = 69; 85%), which showed a higher median age compared to subclass B patients (26 years vs. 15 years). Subclass B cases (n = 12; 15%) showed shorter progression-free survival (P &lt; 0.01). Gene expression analysis of ICMT showed key overexpressed markers in ICMT, with significant CREM overexpression regardless of fusion type, when compared to either meningioma alone or a larger group of CNS tumors. Conclusions This work provides further characterization of ICMT as an important CNS mesenchymal neoplasm that is prone to tumor recurrence, showing 2 prognostically relevant methylation subclasses and warranting diagnostic distinction from other epigenetically and histologically related tumors. ICMTs show substantial overexpression of the CREM gene, independent of fusion type.

Abstract Background Ventricular arrhythmias (VAs) are a proximate mechanism of sudden cardiac death, yet national patterns in place of death (POD) and their determinants remain sparsely described. We quantified 25-year trends and factors associated with POD among UAs decedents in the United States. Methods We analyzed CDC WONDER Multiple Cause of Death data (1999–2024) for adults ≥25 years with ventricular arrhythmias (ICD-10 I47.2, I49.0) as underlying cause. POD was categorized as inpatient, outpatient/emergency department (ED), home, hospice/nursing, or other/unknown. Covariates included age, sex, race, Hispanic origin, and urbanization. We calculated Annual and Average Annual Percent Changes (AAPCs and APC) using Age-Adjusted Mortality Rates (AAMRs), and fit multinomial logistic regression (reference = inpatient) to obtain adjusted odds ratios (ORs, 95% CIs). Results Among 433,988 ventricular arrhythmia (VA) deaths, POD was inpatient 62.0%, outpatient/ED 18.1%, home 11.1%, hospice/nursing 5.8%, other 3.1%. Inpatient deaths increased from 57.8% (1999) to 66.1% (2024). AAMRs declined sharply from 13.3 per 100,000 in 1999 to 6.3–6.5 during 2010–2019, then rose to 7.4 in 2021 and fell to 6.8 in 2024. In home vs inpatient: ≥85 years, medium/small metropolitan counties and rural counties had higher odds of VA deaths, whereas younger age groups, females, Black, American Indian, Asian/Pacific Islander individuals and Hispanic individuals had lower odds. In outpatient/ED vs inpatient: 25–44 years, 45–64 years, males, Black, American Indian and Asian/Pacific Islander individuals had higher odds, whereas ≥85 years and females had lower odds. In hospice/nursing facilities: ≥85 years, females, Whites, non-Hispanic individuals, medium/small metropolitan counties and rural counties had higher odds of VA deaths, whereas younger age groups, Black, American Indian, Asian/Pacific Islander individuals and Hispanic individuals had markedly lower odds. Conclusion From 1999–2024, VA deaths shifted toward hospitals. Persistent disparities by age, sex, race/ethnicity, and rurality highlight the need to expand equitable advance care planning and device deactivation discussions.

BACKGROUND AND OBJECTIVES: Unruptured intracranial aneurysms (UIAs) are increasingly detected and require careful management to prevent rupture. No externally validated score currently predicts procedural risk to guide treatment decisions. We developed and validated 2 predictive scores for complications after endovascular treatment (EVT) or neurosurgical treatment (NT) of UIA using routinely collected clinical and aneurysmal features. METHODS: We conducted a multicenter retrospective study including patients with UIA treated with EVT or NT across 15 neurovascular centers (2014-2024). Predictive models were built using multivariable logistic regression, with variables derived from Delphi consensus. The primary outcome was a composite safety end point: new neurological deficits, modified Rankin Scale (mRS) worsening (≥1 point or mRS 2-5 within 30 days), or procedural death. Internal validation used bootstrapping, and external validation was performed temporally and institutionally. Model performance was assessed using area under the receiver operating characteristic curve (AUROC) and calibration. Final scores, named Morbidity and Mortality Associated Risk in the Treatment of UIAs (MARTA)-EVT and MARTA-NT, were compared with existing models identified through systematic review. RESULTS: Among 2647 patients (1907 EVT and 740 NT), procedural complications occurred in 6.3% (EVT) and 12.8% (NT). Independent predictors included age, baseline mRS, aneurysm location, size, morphology, and procedural factors. MARTA-EVT (AUROC = 0.68, 95% CI = 0.57-0.78) and MARTA-NT (AUROC = 0.65, 95% CI = 0.54-0.77) showed moderate discrimination and good calibration. MARTA-EVT outperformed existing models; MARTA-NT performed similarly to SAFETEA. Predictive models are available open-source: https://martascoreapp.shinyapps.io/martascoreapp/. CONCLUSION: MARTA-EVT and MARTA-NT are validated tools for predicting procedural risks in UIA treatment and may support patient counseling and clinical decision making.

Abstract Motivation: Epilepsy is a diverse group of neurological disorders affecting over 50 million people worldwide. While common epilepsy types are well studied, rare epilepsies—often severe and genetically complex—pose significant challenges in diagnosis, research, and treatment. Accurate and interoperable etiology and disease classifications are critical for improving data sharing, supporting clinical decision-making, and advancing rare disease research. Results: To enhance the accuracy of epilepsy-related disease concept representation within the Mondo Disease Ontology (Mondo), we conducted a series of expert-driven workshops in collaboration with the team from the Rare Disease Cures Accelerator-Data and Analytics Platform (RDCA-DAP). Specialists in epileptology, genetics, neurodevelopment, biomedical ontology, and patient community advocates systematically reviewed and revised the epilepsy hierarchy in Mondo, aligning it with the International League Against Epilepsy (ILAE) classification system. These updates include reclassification of epilepsy subtypes, including syndromes, age-related epilepsies, and developmental epileptic encephalopathies, resulting in a more granular, standardized, and clinically relevant structure. Mondo now offers an enhanced framework for integrating epilepsy data across resources, enabling improved interoperability and facilitating rare disease research and data curation, with continued efforts underway to further refine and expand this integration.
