Voxel-Based Lesion Mapping of Cryptogenic Stroke in Patients with Advanced Cancer: A Detailed Magnetic Resonance Imaging Analysis of Distribution Pattern
Ischemic stroke is one form of cancer-associated thrombosis that can greatly worsen a patient's performance status. The present investigation aimed to elucidate the characteristic distribution pattern(s) of cryptogenic stroke lesions using a voxel-based lesion-mapping technique and examine the differences in clinical manifestations between cryptogenic and conventional strokes in patients with advanced cancer.

Recurrent Ischemic Stroke in a Patient with the Trousseau Syndrome Treated with Dabigatran
A 70-year-old man with multiple ischemic strokes was diagnosed with cardiac embolism and treated with dabigatran. Three months later, he suddenly developed vertigo and vomiting. Magnetic resonance imaging, showed recurrent lesions and blood tests revealed hypercoagulability, hypoproteinemia, and elevated cytokeratin 19 fragments that serve as a tumor marker of lung cancer. Chest computed tomography showed there were small nodules in bilateral lungs and swollen mediastinal lymph nodes. A conclusive diagnosis was impossible because the patient declined invasive procedures. We suspected primary lung cancer and diagnosed conco...

Fatal Intracranial Hemorrhage after Intravenous Thrombolytic Therapy for Acute Ischemic Stroke Associated with Cancer-related Nonbacterial Thrombotic Endocarditis
Nonbacterial thrombotic endocarditis (NBTE) is associated with hypercoagulability in patients with inflammatory states such as cancer and autoimmune diseases. Cardiac vegetations caused by NBTE often lead to life-threatening systemic thromboembolism that most frequently affects the brain, spleen, and kidneys. A 54-year-old woman diagnosed with ovarian cancer suddenly developed back pain and left hemiparesis. Although intravenous alteplase (rt-PA) therapy was administered to treat hyperacute ischemic infarction detected by magnetic resonance imaging, intracranial hemorrhage occurred in the left hemisphere several hours late...

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...

A Post-hoc Study of D-Amino Acid Oxidase in Blood as an Indicator of Post-stroke Dementia
In conclusion, our data support that plasma DAO levels were increased in PSD patients and correlated with brain WMH, independent of age, gender, hypertension, and renal function. Plasma DAO levels may therefore aid in PSD diagnosis. Introduction Stroke is a risk factor for both vascular dementia and Alzheimer's disease (1, 2). Functional recovery develops over the course of 26 weeks after a stroke (3), but the survivors are often left with disabilities. In addition to the sequelae of acute neuronal damage, the 1-year post-stroke dementia (PSD) rates after first-ever and recurrent stroke are ~10 and 30...

Shengui Sansheng San Ameliorates Cerebral Energy Deficiency via Citrate Cycle After Ischemic Stroke
Conclusion In summary, SSS extraction significantly ameliorates cerebral energy metabolism via boosting citrate cycle, which mainly embodies the enhancements of blood glucose concentration, glucose and lactate transportation and glucose utilization, as well as the regulations of relative enzymes activities in citrate cycle. These ameliorations ultimately resulted in numerous ATP yield after stroke, which improved neurological function and infarcted volume. Collectively, it suggests that SSS extraction has exerted advantageous effect in the treatment of cerebral ischemia. Ethics Statement All animal operations were accor...

Stroke and cancer
Rev Neurol (Paris). 2023 Apr 4:S0035-3787(23)00891-3. doi: 10.1016/j.neurol.2023.03.009. Online ahead of print.ABSTRACTAssociation between stroke and cancer is well-established and has led to a growing literature over the past decades. Risk of ischemic and hemorrhagic stroke is increased among patients with newly diagnosed cancer and 5-10% of stroke patients bear an active cancer. All cancers are concerned, but hematological malignancy in childhood and adenocarcinoma from lung, digestive tract and pancreas in adults are most usually identified. Unique stroke mechanisms are dominated by hypercoagulation, a condition that ma...

Outcome of 312 Japanese Patients with Carotid Endarterectomy and Factors Associated with Cardiovascular Events—A Single-center Study in Japan
Background: There have only been a few reports regarding the outcomes and risk factors after CEA. To clarify the factors associated with outcome in patients with carotid stenosis who underwent carotid endarterectomy (CEA), we investigated cardiovascular events and mortality in the Kyushu Medical Center in Japan.Methods: We consecutively registered patients with significant carotid stenosis who had CEA performed over 10 years and compared the incidences of stroke, myocardial infarction, and death. On admission, we evaluated medical records for stroke risk factors, including hypertension, diabetes mellitus, hypercholesterol...

Case Report: Brain Metastasis Confined to the Infarcted Area Following Stroke
Conclusions: Cerebral infarctions can cause neovascularization and disruption of the blood–brain barrier. Moreover, the compartmentalized cavity formed by the ischemic injury may accept a large volume of metastatic tumor cells. Such an altered microenvironment of infarcted tissue would be suitable for the colonization and proliferation of metastatic seed. Further, brain metastases should be considered, in addition to recurrence, when new focal neurological deficits develop in patients with ischemic stroke and comorbid cancer.

Stroke in Children With Cancer: The Tip of the Iceberg?
We read with great interest the article by Noje et al. in which they analyzed the incidence and characteristics of stroke in children with cancer. Among a population of 1411 children with cancer, during a 10-year period registry, 15 children had stroke, corresponding to an overall prevalence of 1%. A slightly increased prevalence of stroke in children with brain tumors was documented (1.3%). The occurrence of stroke in children with brain tumors is potentiated by cranial radiation therapy. We are currently following a cohort of 103 adult survivors of childhood primary central nervous system tumors in our neurooncology c...

Cryptogenic stroke
In about a quarter of ischaemic strokes the cause is undetermined, because the investigation is incomplete or delayed, because there are multiple causes or because the stroke is truly cryptogenic. Cryptogenic stroke can be further classified as non‐embolic or embolic. Embolic stroke of undetermined source can be due to paroxysmal atrial fibrillation, minor emboligenic cardiac conditions, atheroembolism, cancer associated and paradoxical embolism through a patent foramen ovale (PFO) or less often a pulmonary fistula. Currently, risk factor control, statins and antiplatelets are the main therapeutic measures to prevent rec...

Chemotherapy induced stroke mimic: 5-Fluorouracil encephalopathy fulfilling criteria for tissue plasminogen activator therapy
Stroke mimics, especially those involving chemotherapy related neurotoxicity, can confound the clinical diagnosis of acute stroke. Here we describe the case of a 63year-old male with a recent history of stage IIIC colon cancer who presented with confusion on the second day of modified FOLFOX6 (5-fluorouracil/oxaliplatin) chemotherapy and subsequently received alteplase, tissue plasminogen activator therapy (tPA), for presumed ischemic stroke. Magnetic resonance imaging scans after tPA administration did not reveal evidence of an infarction and the patients' neurological symptoms resolved completely after discontinuation of...
