Article Abstract
Background: Cerebral venous thrombosis (CVT) is an uncommon neurological condition usually treated with heparin followed by oral vitamin K antagonists (VKAs). In patients with venous thromboembolism (VTE), compared to VKAs, direct oral anticoagulants (DOACs) offer several advantages. However, there is little data concerning their use in managing CVT.
Aims: This retrospective observational study pursued 2 objectives: (1) to investigate clinical characteristics of CVT patients treated with heparin + DOACs vs. heparin + standard treatment; (2) to compare clinical outcomes.
Methods: Consecutive CVT patients recruited from January 2016 to March 2018 in 2 French university hospitals (Lyon, Saint-Etienne), and treated with DOACs or VKAs were identified. Radiological evolution, VTE, hemorrhagic events, and antithrombotic medication were recorded. Functional outcome was assessed by the modified Rankin scale score and venous recanalization was assessed by magnetic resonance imaging.
Results: Overall, 41 patients were included: 25 (61%) received VKAs and 16 (39%) DOACs. We identified no clinical or radiological features explaining the physicians' preference for a specific anticoagulation treatment, and age, initial clinical presentation, radiological severity, and individual risk factors thus unlikely guided the choice of anticoagulant. No DOAC patient exhibited clinical or radiological thrombosis aggravation, and the thrombosis completely vanished in 6 (40%). Two of the VKA-treated patients (28.6%) demonstrated complete venous recanalization, whereas 3 others experienced clinical or radiological aggravation versus baseline. There was no major bleeding leading to hospitalization in both groups.
Conclusion: The collected data on DOAC efficacy and safety in CVT management appear encouraging, yet needs to be confirmed by larger prospective randomized clinical trials.

Background: Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis fistulas, addressing the existing gap in comprehensive literature.

White matter hyperintensities (WMH) of presumed vascular origin are a magnetic resonance imaging (MRI)-based biomarker of cerebral small vessel disease (CSVD). WMH are associated with cognitive decline and increased risk of stroke and dementia, and are commonly observed in aging, vascular cognitive impairment, and neurodegenerative diseases. The reliable and rapid measurement of WMH in large-scale multisite clinical studies with heterogeneous patient populations remains challenging, where the diversity of imaging characteristics across studies adds additional complexity to this task.

Motor symptom laterality is an important clinical feature of PD that not only manifests as lateral limb dysfunction but also affects the nonmotor symptoms and the prognosis in PD patients. Previous studies suggested that the compensatory mechanisms in the dominant hemisphere of the brain may be an underlying explanation. The corpus callosum (CC) is the largest fiber connecting the two hemispheres of the brain.

Isocitrate dehydrogenase (IDH)-mutant gliomas are the most common malignant primary brain tumors in young adults. This condition imposes a substantial burden on patients and their caregivers, marked by neurocognitive deficits and high mortality rates due to tumor progression, coupled with significant morbidity from current treatment modalities. Although surgery, radiation therapy, and chemotherapy improve survival, these treatments can adversely affect cognitive function, quality of life, finances, employment status, and overall independence.

The ability to integrate semantic information into the context of a sentence is essential for human communication. Several studies have shown that the predictability of a final keyword based on the sentence context influences semantic integration on the behavioral, neurophysiological, and neural level. However, the architecture of the underlying network interactions for semantic integration across the lifespan remains unclear.
