Article Synopsis
  • The study investigates factors leading to early stopping during mechanical thrombectomy (MT) in acute ischemic stroke patients, focusing on those that do not achieve a successful recanalization score (mTICI ≥2b).
  • An analysis of 2,977 patients revealed that factors such as higher age, worse pre-stroke conditions, and certain complications during the procedure were linked to early stopping without successful recanalization.
  • The findings suggest that decisions to stop the procedure often correspond to the patient's overall prognosis, indicating that both favorable and unfavorable conditions can influence the likelihood of early intervention cessation.

Background CT perfusion (CTP)-derived baseline ischemic core volume (ICV) can overestimate the true extent of infarction, which may result in exclusion of patients with ischemic stroke from endovascular treatment (EVT). Purpose To determine whether ischemic core overestimation is associated with larger ICV and degree of recanalization. Materials and Methods This retrospective multicenter cohort study included patients with acute ischemic stroke triaged at multimodal CT who underwent EVT between January 2015 and January 2022.

Background: A sizeable proportion of stroke patients with large vessel occlusion present with minor neurological deficits. Whether mechanical thrombectomy (MT) is beneficial in these patients is controversial. We aimed to investigate factors of early neurological deterioration (END) in thrombectomy patients with minor stroke and hypothesized that END is linked to unfavorable functional outcomes.

Background: There is yet no randomized controlled evidence that mechanical thrombectomy (MT) is superior to best medical treatment in patients with large vessel occlusion but minor stroke symptoms (National Institutes of Health Stroke Scale (NIHSS) <6). Prior studies of patients with admission NIHSS scores 6 observed unfavorable functional outcomes despite successful recanalization, commonly termed as futile recanalization (FR), in up to 50% of cases.

Aim: The aim of this study is to determine the prevalence of FR in patients with minor stroke and identify associated patient-specific risk factors.

Introduction: Tumor budding (TB) refers to the presence of small clusters of tumor cells at the invasive front of a malignant tumor. Single tumor cell invasion (SCI) is an extreme variant of TB, in which individual loose tumor cells are present at the invasive front. Both TB and SCI are important histomorphologic risk factors postulated to indicate loss of cellular cohesion.

Department of Psychology, Faculty of Human Sciences, Medical School Hamburg, Am Kaiserkai 1, Hamburg 20457, Germany; ICAN Institute for Cognitive and Affective Neuroscience, Medical School Hamburg, Am Kaiserkai 1, Hamburg 20457, Germany.

Substance use disorders (SUDs) are severe psychiatric illnesses. Seed region and independent component analyses are currently the dominant connectivity measures but carry the risk of false negatives due to selection. They can be complemented by a data-driven and whole-brain usage of voxel-wise intrinsic measures (VIMs).

Article Synopsis
  • The Alberta Stroke Program Early CT Score (ASPECTS) and penumbral imaging through computed tomography perfusion (CTP) are used to help determine who is eligible for mechanical thrombectomy (MT) in stroke patients.
  • The study hypothesized that the effectiveness of recanalization in patients with large ischemic cores (volume > 50 mL) but high ASPECTS scores (≥6) would be comparable to those with smaller core volumes, and that there could be a tendency to overestimate the core size.
  • Results showed that recanalization did not significantly differ between the two patient groups, and both recanalization and larger core volumes were associated with the overestimation of the ischemic core

Alcohol use disorder (AUD) has been associated with changes in the processing of internal body signals, known as interoception. Changes in brain structure, particularly in the insula, are thought to underlie impaired interoception. As studies specifically investigating this association are largely lacking, this analysis takes an approach that compares meta-analytic results on interoception with recently published meta-analytic results on gray matter reduction in AUD.
