Non-vitamin K Oral Anticoagulants and Anti-seizure Medications: A Retrospective Cohort Study
Conclusions: The recurrent stroke rate of NOAC users with potential DDIs was not higher than in those without potential DDIs in this single-institute study. Our results suggest that theoretical interactions between ASMs and NOACs may not be as severe as previously thought in a real-world situation.

Risk of intracranial hemorrhage with direct oral anticoagulants: a systematic review and meta-analysis of randomized controlled  trials
ConclusionAll DOACs had a lower risk of ICH than VKAs. In terms of the risk of ICH, DOACs were overall as safe as LMWHs, and apixaban and dabigatran were as safe as aspirin, but rivaroxaban was not. For secondary prevention stroke, the risk of ICH with DOACs was overall lower than warfarin and similar to aspirin, but it should be noted that compared with aspirin, rivaroxaban may increase the risk of ICH. This is the first pair-wise meta-analysis that compares the risk of ICH between DOACs and other antithrombotic drugs in detail across all diseases, which may have certain significance for patients with high risk of ICH to ...

Stroke-Induced Peripheral Immune Dysfunction in Vitamin D –Deficient Conditions: Modulation by Progesterone and Vitamin D
AbstractVitamin D deficiency (Ddef) alters morphology and outcomes after a stroke. We investigated the interaction of Ddef following post-stroke systemic inflammation and evaluated whether administration of progesterone (P) or vitamin D (D) will improve outcomes. Ddef rats underwent stroke with lipopolysaccharide (LPS)-induced systemic inflammation. Rats were randomly divided into 9 groups and treated with P, D, or vehicle for 4 days. At day 4, rats were tested on different behavioral parameters. Markers of neuronal inflammation, endoplasmic reticulum stress, oxidative stress, white matter integrity, and apoptosis were mea...

Rivaroxaban in Recurrent Ischemic Stroke Due to Protein S Deficiency: A Case Report
In this study our patient was treated with rivaroxaban. Protein S deficiency may be a predisposing factor in recurrent ischemic stroke, and rivaroxaban can be a safe and effective treatment option. Further studies are needed to confirm our findings.

Challenges of treatment adherence with direct oral anticoagulants in pandemic
Purpose of review Direct oral anticoagulants (DOAC) are crucial for the prevention of thromboembolic events in patients with nonvalvular atrial fibrillation. Drug adherence by the patient but also adherence to guidelines by the physician are suboptimal. This review highlights aspects of DOAC treatment during the coronavirus disease 2019 (COVID-19) pandemic and selected challenging scenarios. Recent findings For patients with a newly diagnosed indication for oral anticoagulation, a new interim clinical guidance recommends starting DOAC instead of vitamin K antagonists if DOAC are not contraindicated. The goal is ...

Residual Stroke Risk in Patients with Atrial Fibrillation Treated with Non-Vitamin K Oral Anticoagulants: An 8-Year Retrospective Cohort Study
Conclusions: Stroke developed in NVAF patients despite being on NOACs, with the majority being female, older, and hypertensive. Surprisingly, in general they had reasonable lipid and diabetic control.Cerebrovasc Dis Extra 2021;11:9 –14

Malignant Left Atrial Appendage Morphology: Current Classification vs H-L System
In non-valvular atrial fibrillation (AF), more than 90% of thrombus formation occurs in the left atrial appendage (LAA).1-3 Current guidelines have established direct oral anticoagulants (DOACs) as the treatment of choice in patients with AF and high risk of stroke or transient ischemic attack (TIA), while vitamin K antagonists (VKA) can be considered in patients not suitable for DOACs.4,5 This strategy significantly reduces the risk of thromboembolism; however, there is a subset of patients that suffer recurrent embolic strokes despite appropriate anticoagulant therapy, known as malignant LAA.

Status epilepticus in neonates and infants
Rajni Farmania, Divyani Garg, Suvasini SharmaAnnals of Indian Academy of Neurology 2020 23(6):747-754 Status epilepticus (SE) is a common neurological emergency in childhood associated with high mortality and morbidity. Acute management of seizures along with aggressive evaluation for establishing the underlying cause are crucial determinants of outcome. Neonatal status epilepticus carries the burden of poor neurological outcomes and may lead to global developmental delay as well as persistent seizures. The aetiology and pathophysiological mechanisms of SE in neonates and young infants differ compared to older children an...

Insights Into Direct Oral Anticoagulant Therapy Implementation of Stroke Survivors with Atrial Fibrillation in an Ambulatory Setting
Atrial fibrillation (AF) is the most common cardiac arrhythmia and increases the risk of ischemic stroke by about five times.1 Oral anticoagulation (OAC) with direct oral anticoagulants (DOAC) or vitamin K antagonists (VKA) reduces ischemic stroke risk in AF patients. Currently, DOAC (apixaban, dabigatran, edoxaban and rivaroxaban) are recommended as first-line treatment for stroke prevention in AF patients.2 Despite several advantages compared to VKA, DOAC have a short half-life of about 12 h. Missing more than 5% of intakes is associated with a higher occurrence of thromboembolic events in OAC-treated AF patients.

Oral Anticoagulation and Risk of Symptomatic Hemorrhagic Transformation in Stroke Patients Treated With Mechanical Thrombectomy: Data From the Nordictus Registry
Conclusions: OAC with VKA, but not with DOACs, was an independent predictor of sICH after mechanical thrombectomy. This excess risk was associated neither with INR value by the time thrombectomy was performed, nor with a worse functional outcome or mortality at 3 months.

Inactivated Four-Factor Prothrombin Complex Concentrate Dosing Practices for Reversal of Warfarin-Related Intracranial Hemorrhage
ConclusionsMost patients received single doses of I4F-PCC, with adjunctive reversal agents and rounding doses to vial size. The time difference from baseline INR to factor product administration is a potential opportunity for process improvement in the management of warfarin-related ICH.

Long-Term Anticoagulation in Secondary Ischemic Stroke Prevention: The Prospective Multicenter RESTAIC Registry
Conclusion: Long-term OAC in secondary stroke prevention is associated with a lower frequency of bleeding complications than stroke recurrences. No differences between anticoagulant drugs were found in any of the analyzed outcomes. The main cause for OAC switch during follow-up was stroke recurrence.

Temporal Trends in Pharmacological Stroke Prevention in Patients with Acute Ischemic Stroke and Known Atrial Fibrillation
Oral anticoagulation (OAC) substantially reduces stroke risk in patients with atrial fibrillation (AF) at risk for stroke. Whether non-vitamin K-dependent oral anticoagulants (NOACs) improve OAC use in stroke prevention requires investigation.

Non-vitamin K oral anticoagulants as first-line regimen for acute ischemic stroke with non-valvular atrial fibrillation
There are various patterns in determining the choice of the first-line antithrombotic agent for acute stroke with non-valvular atrial fibrillation. We investigated the efficacy and safety of non-vitamin K oral anticoagulants as first-line antithrombotics for patients with acute stroke and non-valvular atrial fibrillation.
