Background And Aims: Dysphagia is significantly correlated with prognostic outcomes in patients with stroke; however, the intrinsic mechanism of action between the two remains unclear. This study aimed to model the intrinsic mechanism of action between dysphagia and prognostic outcomes in patients with stroke based on structural equation modeling.
Methods: A retrospective analysis of 900 inpatients with stroke from three large hospitals was performed. AMOS software (version 23.0) was used to construct the structural equation modeling.
Results: The overall model showed a good fit (chi-square = 27.3, root mean square error of approximation = 0.01, standardized root mean square residual = 0.032, comparative fit index = 0.98, and adjusted goodness of fit = 0.94). Structural equation modeling showed that the total effect of dysphagia on the prognosis of patients with stroke was 0.694, with a direct effect of 0.599, accounting for 86.31% of the total effect. The total indirect effect was 0.095, with the mediating effects of serum albumin level and pneumonia accounting for 6.48% and 7.35% of the total effect, respectively. The moderating effects of sex on dysphagia and the relationship between activities of daily living, modified Rankin scale score, and length of hospital stay were insignificant (ΔR2 = 0.063, P = 0.145; ΔR2 = 0.002, P = 0.620; ΔR2 = 0.001, P = 0.307).
Conclusions: Dysphagia can directly affect the prognostic outcomes of patients with stroke and indirectly affect prognosis by triggering pneumonia and lowering albumin levels. Sex was not found to play a moderating role in the relationship between dysphagia and prognosis.

Background: Whether it is effective and safe to extend the time window of intravenous thrombolysis up to 24 hours after the last known well is unknown. We aimed to determine the efficacy and safety of tenecteplase in Chinese patients with acute ischemic stroke due to large/medium vessel occlusion within an extended time window.
Methods: Patients with ischemic stroke presenting 4.

Background: How cerebral microbleeds (CMBs) are formed, and how they cause tissue damage is not fully understood, but it has been suggested they are associated with inflammation, and they could also be related to increased blood-brain barrier (BBB) leakage. We investigated the relationship of CMBs with inflammation and BBB leakage in cerebral small vessel disease, and in particular, whether these 2 processes were increased in the vicinity of CMBs.
Methods: In 54 patients with sporadic cerebral small vessel disease presenting with lacunar stroke, we simultaneously assessed microglial activation using the positron emission tomography ligand [11C]PK11195 and BBB leakage using dynamic contrast enhanced magnetic resonance imaging, on a positron emission tomography-magnetic resonance imaging system.

Background: Predicting treated language improvement (TLI) and transfer to the untreated language (cross-language generalization, CLG) after speech-language therapy in bilingual individuals with poststroke aphasia is crucial for personalized treatment planning. This study evaluated machine learning models to predict TLI and CLG and identified the key predictive features (eg, patient severity, demographics, and treatment variables) aligning with clinical evidence.
Methods: Forty-eight Spanish-English bilingual individuals with poststroke aphasia received 20 sessions of semantic feature-based naming treatment in either their first or second language.

Background: Several social and biological factors are shown to differentially affect stroke outcomes between men and women. We evaluated whether clinical outcomes and endovascular thrombectomy (EVT) treatment effects differed between the sexes in patients presenting with large ischemic stroke.
Methods: The SELECT2 trial (A Randomized Controlled Trial to Optimize Patient's Selection for Endovascular Treatment in Acute Ischemic Stroke) was a randomized controlled trial assessing the efficacy and safety of EVT in patients with large strokes across the United States, Canada, Europe, Australia, and New Zealand between October 2019 and September 2022.

Intracerebral hemorrhage (ICH) is a devastating form of stroke with a lack of effective treatments. Following disease onset, ICH activates microglia and recruits peripheral leukocytes into the perihematomal region to amplify neural injury. Bruton's tyrosine kinase (BTK) controls the proliferation and survival of various myeloid cells and lymphocytes.
