Childhood stroke : What are the special features of childhood stroke?
Abstract Childhood arterial ischemic stroke differs in essential aspects from adult stroke. It is rare, often relatively unknown among laypersons and physicians and the wide variety of age-specific differential diagnoses (stroke mimics) as well as less established care structures often lead to a considerable delay in the diagnosis of stroke. The possible treatment options in childhood are mostly off-label. Experiences in well-established acute treatment modalities in adult stroke, such as thrombolysis and mechanical thrombectomy are therefore limited in children and only based on case reports and case series. The...

Prevalence and covariates of uncontrolled hypertension in ischemic stroke survivors: the Norwegian stroke in the young study.
CONCLUSION: Uncontrolled hypertension was highly prevalent in ischemic stroke survivors <60 years and associated with co-presence of obesity and functional and structural arterial damage. Our results highlight the unmet potential and challenge of optimization of hypertension diagnosis and management in order to prevent recurrent vascular events in ischemic stroke survivors.

Impact of pre-admission treatment with non-vitamin K oral anticoagulants on stroke severity in patients with acute ischemic stroke
ConclusionsWe report a positive impact of pre-admission NOAC on ischemic stroke severity, which is particularly remarkable in light of the increased prevalence of prior stroke and lower rates of thrombolysis in this patient population.

Interleukin-1 receptor inhibition reduces stroke size in a murine model of sickle cell disease.
Abstract Sickle cell disease (SCD) is associated with chronic hemolytic anemia and a heightened inflammatory state. The causal role of inflammatory pathways in stroke associated with SCD is unclear. Therefore, the hypothesis that deletion of the non-hematopoietic interleukin-1 receptor (IL-1R) pool may be beneficial in SCD was pursued. Since potential deleterious effects of IL-1R signaling in SCD could be mediated via downstream production of interleukin-6 (IL-6), the role of the non-hematopoietic IL-6 pool was also addressed. Bone marrow transplantation (BMT) from SCD to wild-type (WT) recipient mice was used to ...

Routine surveillance of pelvic and lower extremity deep vein thrombosis in stroke patients with patent foramen ovale
AbstractPatent foramen ovale (PFO) is a potential conduit for paradoxical embolization to the systemic atrial circulation of a thrombus originating in the venous system. In a selected group of subjects, the prevalence of deep vein thrombosis (DVT) was assessed. Subjects were identified if they underwent magnetic resonance venography (MRV) pelvis and lower extremity doppler (LE-VDU) for assessment of DVT with PFO. The primary outcome measure was to report the number of patients with paradoxical embolization as their suspected etiology of stroke due to the presence of DVT, which then will be considered as determined stroke. ...

Coagulation factor XII, XI, and VIII activity levels and secondary events after first ischemic stroke.
CONCLUSIONS: In our study of mild to moderate ischemic stroke patients, high activity levels of FXI and FVIII but not FXII were associated with worse vascular outcomes in the three-year period after first ischemic stroke. PMID: 32935900 [PubMed - as supplied by publisher]

The use of recombinant tissue plasminogen activator in in acute ischemic stroke is associated with increased level of BDNF
This study was conducted on 47 patients presenting with acute ischemic stroke (during the first 4.5  h from stroke onset); 26 patients of them eligible for receiving rt-PA (patient group) and 21 patients having contraindications for treatment with rt-PA (control group). Neurological, radiological and laboratory assessment (including BDNF serum level) were done for both groups at stroke onset (bef ore receiving rt-PA) and at day 7. There was a statistically significant increase in BDNF serum level from day 1 to day 7 in rt-PA treated patients in comparison to control group (P-value˂ 0.001). Serum level of BDNF is signific...

Associations of Coagulation Factor X and XI with Incident Acute Coronary Syndrome and Stroke: A Nested Case-Control Study
CONCLUSION: FXI levels were associated with a greater risk of incident ischemic stroke but not hemorrhagic stroke or ACS. FX levels were not associated with incident ACS or stroke.PMID:34351069 | DOI:10.1111/jth.15486

Age at smoking initiation and smoking cessation influence the incidence of stroke in China: a 10-year follow-up study
In conclusion, we found that current smokers had a higher stroke risk than never smokers, and the risk increased with a younger age at smoking in itiation. Smoking cessation can reduce the risk for stroke, especially could benefit from cessation at a younger age.

Prediction of ischemic stroke in young Indians: is thrombophilia profiling a way out?
Stroke in the young is attributed to the prevalence of thrombophilia, however, reports explaining the cause mechanisms from Indian populations are largely not known. The information about the association of inherited thrombophilia and occurrence of stroke is still missing. Therefore, we describe here 52 cases of young ischemic stroke of which 22 cases were of recurrent stroke and 30 cases of first episode stroke along with an equal number of healthy controls. Imaging techniques (CT/MRI/Doppler studies) were used to identify the type and location of infarcts among various regions of the brain. All the patients and controls ...

Retinal vein and artery occlusions: a risk factor for stroke in atrial fibrillation
ConclusionsA history of retinal arterial or retinal venous occlusion is associated with an increased risk of stroke/TE/TIA in patients with atrial fibrillation. Thus, prior retinal vascular occlusion may be considered as a previous thromboembolic event when evaluating stroke risk in patients with atrial fibrillation.

Cytoprotective-selective activated protein C therapy for ischaemic stroke.
Abstract Despite years of research and efforts to translate stroke research to clinical therapy, ischaemic stroke remains a major cause of death, disability, and diminished quality of life. Primary and secondary preventive measures combined with improved quality of care have made significant progress. However, no novel drug for ischaemic stroke therapy has been approved in the past decade. Numerous studies have shown beneficial effects of activated protein C (APC) in rodent stroke models. In addition to its natural anticoagulant functions, APC conveys multiple direct cytoprotective effects on many different cell t...
