Objective The objective of this study was to investigate the association between dual seropositive, single seropositive, and seronegative rheumatoid arthritis (RA) with radiographic erosions, disease flares, and death. Methods We performed a retrospective, population‐based study of residents in Southern Minnesota with incident RA who fulfilled criteria for RA in 2003 to 2019. Radiographic erosions and flares were evaluated within one year of incident RA. All‐cause mortality was obtained from medical records and death certificates. Cox models adjusted for age, sex, smoking status, year of incident RA, and comorbidities were used. Results The study included 1,373 patients with RA. At RA incidence, 37% were dual seropositive, 13% seropositive for anti–cyclic citrullinated protein (anti‐CCP) only, 12% seropositive for rheumatoid factor (RF) only, and 38% seronegative. The highest proportion of radiographic erosions before or within one year of RA incidence was in the dual seropositive (31%) and lowest in those seropositive for anti‐CCP only (13%). Flares occurred in 69% of the dual seropositive and 51% of the seropositive for anti‐CCP only within the first year of RA incidence. Those seropositive for RF only had over a two‐fold increase in mortality rates compared with the seronegatives (adjusted hazard ratio [aHR] 2.18, 95% confidence interval [CI] 1.47–3.24). In contrast, the dual seropositives had only a >50% increase in mortality rates (aHR 1.66, 95% CI 1.21–2.28), and those seropositive only for anti‐CCP had a >30% increase in mortality rates (aHR 1.32, 95% CI 0.83–2.11). Conclusion Patients with RA seropositive for RF only have an increase in mortality rates compared with patients who are dual seronegative. RF positivity could be an indicator of inflammation that requires pharmacologic treatment to decrease mortality rates.

Abstract Measurable residual disease (MRD) assessment has become central to risk-adapted treatment strategies in multiple myeloma, yet the prognostic value of MRD negativity following autologous stem cell transplantation (ASCT) across individual high-risk cytogenetic abnormalities (HRCAs) remains unclear. We analyzed 351 newly diagnosed patients who achieved MRD negativity (sensitivity 2.4×10 − 6 ) at Day 100 following ASCT and had baseline cytogenetic data available. Median follow-up was 50.4 months. Standard-risk cytogenetics were present in 46% (n = 162), while 34% (n = 118) had one HRCA and 20% (n = 71) had ≥ 2 HRCAs. Despite uniform MRD negativity, several HRCAs continued to confer inferior progression-free survival (PFS). Compared with the standard-risk group (4-year PFS 84%), patients with del(17p), 1q21+, t(4;14), or MAF translocations [t(14;16)/t(14;20)] had significantly lower 4-year PFS rates: 56% (HR 2.89; p = 0.0001), 60% (HR 2.46; p = 0.0001), 43% (HR 3.50; p = 0.0001), and 58% (HR 2.51; p = 0.01), respectively. Isolated del(17p) and 1q21 + also conferred inferior PFS. The 4-year PFS was 65% for patients with one HRCA (HR 2.31; p = 0.0004) and 55% for those with ≥ 2 HRCAs (HR 2.75; p = 0.0001). In this large MRD-negative post-ASCT cohort, several HRCAs, including isolated HRCAs, remained clinically meaningful drivers of inferior PFS, highlighting that early MRD negativity does not uniformly mitigate the impact of high-risk biology.

Abstract Introduction Cardiac CT is increasingly used to screen for cardioembolism in stroke patients. We assessed the frequency and management of non-cardiac incidental findings on prospective ECG-gated cardiac CT in patients with a suspected stroke. Patients and methods This was a post-hoc analysis of the Mind the Heart study, a prospective single-centre cohort study including consecutive adult patients with acute ischaemic stroke (AIS), transient ischaemic attack (TIA), or a stroke mimic who underwent cardiac CT as part of an acute stroke imaging protocol. Endpoints were pre-defined non-cardiac incidental findings that were detected on cardiac CT: pulmonary embolism (PE), potential malignant lesions, pulmonary consolidations or ground-glass densities, bone fractures, lymphadenopathy, focal liver lesions, and ascending aortic or pulmonary artery dilatation. Change of management was defined as additional treatment or follow-up. Results We included 654 patients (57% men, median age 71 [IQR 59–80] years) of whom 451 (69%) had AIS, 48 had TIA (7%), and 155 had a stroke mimic (24%). Overall, 58 non-cardiac incidental findings were found in 55 (8%; 95%CI, 6–11) patients. The most frequent incidental findings were consolidations or ground-glass densities (n = 17, 3%), liver cysts or non-specific hypodensities (n = 14, 2%), pulmonary nodules or masses (n = 9, 1%), and PEs (n = 8, 1%). Incidental findings led to a change of management in 17/55 (31%) patients of whom 13/55 (24%) had additional follow-up and 9/55 (16%) received treatment (anticoagulation n = 8, chemotherapy n = 1). Discussion & Conclusion Non-cardiac incidental findings were observed on cardiac CT in 8% of patients with a suspected stroke. These findings changed management in 31% of these patients.

Abstract 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 Introduction Cervical arterial dissections (CeAD) can involve either single (sCeAD) or multiple (mCeAD) arteries. Whether the involvement of a single versus multiple arteries is associated with outcomes remains unclear. We aimed to study associations between the number of affected arteries and clinical, imaging and outcome parameters. Patients and methods Patients with CeAD from the STOP-CAD multicenter registry study were included. Clinical, imaging, treatment and outcome parameters were compared between patients with sCeAD and mCeAD. Regression analyses were performed to identify associations with multi-arteries involvement. Results Overall, 3858 STOP-CAD patients were included in this analysis and 443 (11.5%) had mCeAD. The presence of mCeAD was associated with age (adjusted odds ratio [aOR] 95% confidence intervals [95% CI] 0.99; (0.98–1.00)), female sex (aOR 1.5; 95% CI 1.17–1.91), recent upper respiratory infection (aOR 2.25; 95% CI 1.55–3.27), presence of connective tissue disease (aOR 3.11; 95% CI 2.32–4.17), severe arterial stenosis (aOR 1.95; 95% CI 1.95–2.58), intracranial extension (aOR 1.47; 95% CI 1.04–2.09), vertebral artery involvement (aOR 2.50; 95% CI 1.94–3.22) and presence of dissecting aneurysm (aOR 2.59; 95% CI 1.95–3.42). In adjusted analyses, mCeAD was not associated with clinical outcomes (ischemic stroke, mortality, and sICH; all p > 0.05). Conclusions mCeAD does not appear to increase risk of subsequent stroke as compared to sCAD despite baseline risk factors suggestive of vasculopathy. mCeAD patients who did develop a stroke presented with milder strokes and less often had vessel occlusions compared to those with sCeAD. The presence of mCeAD did not impact outcomes.

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.

Objectives Multiple system atrophy (MSA) is classified into parkinsonian (MSA‐P) and cerebellar (MSA‐C) phenotypes based on predominant motor features, with corresponding pathological classifications of striatonigral (SN) degeneration and olivopontocerebellar (OPC) atrophy; however, disease progression patterns remain poorly understood. We aimed to identify novel MSA subtypes based on neuronal loss patterns using unsupervised machine learning. Methods We applied the Subtype and Stage Inference (SuStaIn) algorithm to analyze neuronal loss patterns in 167 autopsy‐confirmed MSA. Neuronal loss was semi‐quantitatively assessed in 5 brain regions: putamen, substantia nigra, pontine nucleus, inferior olivary nucleus, and cerebellar Purkinje cells. Obtained subtypes were validated by clinicopathological information. Results Three distinct subtypes were identified: SN‐early subtype (54% [86/160]) with initial SN neuronal loss, OPC‐early subtype (28% [44/160]) with early OPC involvement, and SN‐OPC‐synchronous subtype (19% [30/160]) with concurrent early neuronal loss in both systems. These subtypes corresponded well with clinical phenotypes. The SN‐OPC‐synchronous subtype exhibited significantly shorter survival (median 6.2 years vs 6.9 and 7.4 years in SN‐early and OPC‐early subtypes; p = 0.0049), more frequent rapid progression (57% vs 24% and 41% in SN‐early and OPC‐early subtypes; p = 0.0048), and more frequent early falls (70% vs 36% and 50% in SN‐early and OPC‐early subtypes; p = 0.0039). Immunohistochemical validation confirmed extensive α‐synuclein pathology in both SN and OPC systems in the SN‐OPC‐synchronous subtype. Interpretation The SN‐OPC‐synchronous subtype provides insights into α‐synuclein propagation mechanisms, suggesting multiple initial seeding sites rather than unidirectional spread. This computational approach uncovered disease heterogeneity undetectable by conventional methods, potentially benefiting clinical trials through patient stratification. ANN NEUROL 2026;99:989–1000

Background/Objectives: Postoperative opioid exposure after lumbar fusion remains a key clinical concern. Understanding which perioperative factors are associated with lower postoperative opioid use may help optimize recovery after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF). This study aimed to determine if patients undergoing MIS-TLIF under spinal anesthesia (SA) showed lower postoperative opioid use compared to those undergoing MIS-TLIF under general anesthesia (GA). Methods: We retrospectively studied all adult patients (>18 years) undergoing 1- and contiguous 2-level MIS-TLIFs performed by a single surgeon. Patients undergoing the procedure under GA were compared to those undergoing the procedure under SA. Postoperative oral opioid use, up to 3 months post discharge, was collected. A 1:1 propensity score matching (PSM) protocol was implemented. Each outcome variable was initially assessed using univariate regression. Predictor variables with a p-value < 0.2 were included in the multivariate regression model. This was a retrospective, non-randomized study, and residual confounding cannot be excluded despite PSM. Results: The matched groups (n = 50 in each group) did not differ significantly depending on demographics or levels fused. Before regression, mean number of postoperative opioid prescriptions (p = 0.03), mean total operating room (OR) time in minutes (p < 0.01), and median length of stay (LOS) in days (p = 0.03) were significantly different. Multivariate regression showed that the GA group received 216.5 more total morphine milligram equivalents than the SA group (95% CI = 0.7–432.2, p = 0.049). The days of opioid use were higher in the GA group by 3.8 days (95% CI = 0.5 to 7.1, p = 0.025). On multivariate regression, LOS in hours was greater in the GA group by 14.1 h (p = 0.042). Conclusions: SA is an effective anesthetic modality for spinal surgery with the advantages of reduced postoperative opioid use, reduced OR time, and shorter LOS compared to GA.

Background: Transradial artery access (TRA) is the favored approach for percutaneous coronary intervention (PCI) and coronary angiography (CAG). However, transulnar artery access (TUA) has emerged as an alternative, particularly when TRA is not feasible. This systematic review and meta-analysis aims to compare the efficacy and safety of TUA versus TRA in patients undergoing PCI and CAG. Methods: From inception to August 2025, a systematic search of electronic databases was conducted. Data were synthesized using a random-effects model, and heterogeneity was assessed using the I 2 statistic. Results: Nine RCTs involving 6089 patients were included. Meta-analysis revealed no significant difference in procedural success between TUA and TRA (RR: 0.93, 95% CI: 0.82–1.06, P = 0.28, I 2 = 99%). Similarly, puncture success rates were comparable (RR: 0.95, 95% CI: 0.91–1.00, P = 0.06, I 2 = 83%). Secondary outcomes showed no significant differences in puncture attempts or hematoma incidence, but TRA was associated with a shorter procedure time (MD: 0.89, 95% CI: 0.27–1.50, P = 0.005). Conclusion: TUA provides a viable alternative to TRA, with similar success rates and complication profiles. However, TRA remains superior in terms of procedure time. Further large-scale RCTs are warranted to confirm these findings and refine clinical guidelines.

ABSTRACT Introduction Extracorporeal membrane oxygenation (ECMO) is a life‐saving intervention for refractory cardiopulmonary failure. Despite advancements reducing complications, ECMO remains associated with acute kidney injury (AKI), often requiring kidney replacement therapy (KRT). Studies report up to 45% of ECMO patients needing KRT, significantly increasing mortality. A prior meta‐analysis suggested a declining mortality trend in recent years. Methodology Following PRISMA guidelines, PubMed, MEDLINE, EMBASE, and Cochrane Library were searched (2000–2024) for randomized and observational studies on adult ECMO patients requiring KRT. Data extraction covered study characteristics, patient demographics, ECMO type, KRT timing, and clinical outcomes. Quality was assessed using the Newcastle–Ottawa Scale. Statistical analyses were performed using RevMan 5.4.1 under a random‐effects model, with mortality as the primary outcome. Result A total of 24 studies (6347 patients) met the inclusion criteria, including 23 observational studies and one RCT. The mean age of ECMO + KRT patients was 51 years in observational studies and 61.2 years in the RCT, with cardiogenic shock as the most common ECMO indication. Meta‐analysis showed a significantly higher mortality in ECMO + KRT patients (RR: 1.86, 95% CI: 1.63–2.12, p < 0.001), with infections and bleeding as key contributors. Subgroup analysis revealed no significant survival difference based on KRT timing, while Veno‐arterial extracorporeal membrane oxygenation (VA‐ECMO) was associated with worse outcomes than Veno‐venous extracorporeal membrane oxygenation (VV‐ECMO). The RCT reported 61.9% mortality at 30 days in ECMO + KRT patients. Conclusion KRT during ECMO is associated with increased mortality, likely due to the severity of illness and complications like infections and bleeding. The optimal timing of KRT initiation remains unclear, and no significant survival benefit was found for early KRT. Further large‐scale RCTs are needed to optimize management strategies.
