Stroke propensity in the Th3+/ mouse model of β-thalassemia intermedia
Neurobiol Dis. 2022 Jun 23:105802. doi: 10.1016/j.nbd.2022.105802. Online ahead of print.ABSTRACTβ-thalassemia is associated with multiple hematological and cerebrovascular symptoms linked to a hypercoagulable state that has not been fully replicated in animal models for the development of stroke treatments. Herein we compared the physiological properties and responses to transient cerebral hypoxia-ischemia (tHI) between six-month-old wildtype and heterozygous Th3/+ mice, a model of non-transfusion-dependent β-thalassemia intermedia (β-TI). We found that Th3/+ mice developed microcytic anemia, splenomegaly, higher plate...

Cerebral venous thrombosis following COVID-19 vaccination
We appreciate the literature review by Abdalkader et al.1 to summarize the clinical epidemiology and features of cerebral venous thrombosis (CVT) in patients with coronavirus disease 2019 (COVID-19). Based on the meta-analysis performed by Baldini et al.,2 the estimated proportion of CVT cases among hospitalized patients with COVID-19 was 0.08%; therefore, it is not surprising that COVID-19 associated CVT had not been given much attention compared to the more common deep vein thrombosis and pulmonary embolism events in this patient population.

Anticoagulant approach in COVID-19 patients with cerebral venous thrombosis
We appreciate Klein et al. [1] for reporting the case of cerebral venous thrombosis accompanied by hemorrhagic infarct in a young patient with novel coronavirus disease 2019 (COVID-19). The reporting of such a case would raise the awareness of the possibility of the occurrence of cerebral venous thrombosis in the course of COVID-19, especially among the young adults present with COVID-19 and neurological symptoms.

Sickle Mice Are Sensitive to Hypoxia/Ischemia-Induced Stroke but Respond to Tissue-Type Plasminogen Activator Treatment Basic Sciences
Conclusions—Sickle mice are sensitive to hypoxia/ischemia-induced cerebral infarct but benefit from thrombolytic treatment. An increased resistive index in carotid arteries may be an early marker of sickle cell vasculopathy.
