Beneficial actions of prothymosin alpha-mimetic hexapeptide on central post-stroke pain, reduced social activity, learning-deficit and depression following cerebral ischemia in mice
Publication date: Available online 23 January 2020Source: PeptidesAuthor(s): Keita Sasaki, Sebok Kumar Halder, Hayato Matsunaga, Hiroshi UedaAbstractProthymosin alpha (ProTα)-mimetic hexapeptide (amino acid: NEVDQE, P6Q) inhibits cerebral or retinal ischemia-induced behavioral, electrophysiological and histological damage. P6Q also abolishes cerebral hemorrhage induced by ischemia with tissue plasminogen activator (tPA). In the present study we examined the beneficial effects of P6Q on other post-stroke prognostic psychology-related symptoms, which obstruct the motivation toward physical therapy. Intravenous (i.v.) admini...

Why we fail: mechanisms and co-factors of unsuccessful thrombectomy in acute ischemic stroke
ConclusionIn 20% of failing MT, thrombus cannot be reached/passed. Direct carotid puncture or surgical arterial access could be considered in these cases.In 80% of failing interventions, thrombus can be passed with the device, but the occluded vessel cannot be recanalized. Rescue techniques can be an option. Development of new devices and techniques is necessary to improve recanalization rates. Assessment of pre-existing illness could sensitize for occurring complications.

IJERPH, Vol. 17, Pages 618: Risk Factors Associated with Outcomes of Recombinant Tissue Plasminogen Activator Therapy in Patients with Acute Ischemic Stroke
eng Tsong-Hai Lee Ischemic stroke is the most common type of stroke, and early interventional treatment is associated with favorable outcomes. In the guidelines, thrombolytic therapy using recombinant tissue-type plasminogen activator (rt-PA) is recommended for eligible patients with acute ischemic stroke. However, the risk of hemorrhagic complications limits the use of rt-PA, and the risk factors for poor treatment outcomes need to be identified. To identify the risk factors associated with in-hospital poor outcomes in patients treated with rt-PA, we analyzed the electronic medical records of patients who were diagn...

Similar thrombolysis outcomes in acute stroke patients with and without atrial fibrillation if pre-stroke CHA2DS2-VASc score is low: A retrospective study
The prognosis of acute ischemic stroke patients treated with intravenous (IV) recombinant tissue plasminogen activator (rtPA) is poorer in patients with atrial fibrillation (AF) than patients without AF, which might be related to the greater stroke severity in AF patients. Higher pre-stroke CHA2DS2-VASc scores are associated with greater stroke severity and poorer outcomes. AF Patients tend to have higher CHA2DS2-VASc scores than the non-AF patients. We thus hypothesized that pre-stroke CHA2DS2-VASc scores can be used to improve outcome stratification of IV thrombolysis therapy in acute stroke patients with and without AF....

von Willebrand Factor and Platelet Glycoprotein Ib: A Thromboinflammatory Axis in Stroke
von Willebrand factor (VWF) and platelets are key mediators of normal hemostasis. At sites of vascular injury, VWF recruits platelets via binding to the platelet receptor glycoprotein Ibα (GPIbα). Over the past decades, it has become clear that many hemostatic factors, including VWF and platelets, are also involved in inflammatory processes, forming intriguing links between hemostasis, thrombosis, and inflammation. The so-called “thrombo-inflammatory” nature of the VWF-platelet axis becomes increasingly recognized in different cardiovascular pathologies, making it a potential therapeutic target to interfere with both...

mtDNA Copy Number Contributes to All-Cause Mortality of Lacunar Infarct in a Chinese Prospective Stroke Population
AbstractThe study aimed to investigate the relationship between mtDNA copy number and the risk of all-cause mortality in stroke. One thousand four hundred eighty-four stroke patients were documented including 273 deaths (127 thrombosis, 52 lacunar, 94 hemorrhage). Patients in the third quartile had the lowest mortality rates in overall stroke and the three subtypes. The lowest quartile of mtDNA copy number (Q1< 85.85) indicated an increased risk of all-cause mortality in stroke patients (adjusted HR, 1.52; 95% CI, 1.08–2.14;p = 0.017). In the subtype analysis, the risk of all-cause mortality appeared only in la...

Bilateral anterior cerebral artery infarction presenting with acute paraparesis and parkinsonism
In patients with acute-onset paraparesis inferior, the concurrent presence of new onset cortical signs (abulia or mutism), and more rarely extrapyramidal signs, should alert clinicians to consider acute anterior bihemispheric ischemia. Prompt recognition of this rare form of acute cerebral stroke can enable timely delivering of acute thrombolytic or endovascular treatment.

Left Atrial Appendage Occlusion in the Management of Stroke in Patients With Atrial Fibrillation
Atrial fibrillation (AF) is associated with a substantially higher risk of thromboembolism, particularly stroke events, resulting in significant morbidity and mortality. Oral anticoagulation (OAC), while effective in reducing embolic events in AF patients, is associated with an increased bleeding risk. Thus, not all patients with AF are candidates for OAC and some are only candidates for OAC in the short term. Of the available nonpharmacologic strategies for the management of AF, left atrial appendage occlusion (LAAO) has emerged as a potential approach for reducing the risk of systemic thromboembolism in AF patients eligi...

Subtype-Dependent Reporting of Stroke With SGLT2 Inhibitors: Implications From a Japanese Pharmacovigilance Study.
Abstract Volume depletion as an adverse events (AE) caused by sodium-glucose cotransporter-2 inhibitors (SGLT2i) because of their diuretic effect may raise the concern about the risk of lacunar stroke; however, an earlier meta-analysis reported no significant increase in the incidence of stroke without clearly distinguishing stroke subtypes. Here, aiming to investigate subtype-wise reporting of stroke potentially related to SGLT2i treatment, we conducted a disproportionality analysis using the Japanese Adverse Drug Event Report database, which contains approximately 500 000 cases recorded between April 2004 and M...

An unusual cause of acute ischemic stroke: Adult Onset Still ’s Disease
We present a case where acute ischemic stroke secondary to a floating internal carotid artery thrombus was an early manifestation of AOSD. The patient also had prolonged high spiking fevers, sign ificant leucocytosis, arthralgias and transaminitis. He responded well to a high dose of oral corticosteroids and was eventually started on anticoagulation for secondary stroke prevention. To our knowledge, this is the first described case of arterial thrombosis associated with AOSD. We postulate th at thrombocytosis, vasculitis and hypercoagulability from the underlying inflammatory state may have contributed to the ischemic stroke.

Timing of Initiation of Oral Anticoagulation after Acute Ischemic Stroke in Patients with Atrial Fibrillation
AbstractPatients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post ‐stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transfo rmation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemo...

CONCLUSION Patients who suffer BCVI-related stroke are hypercoagulable compared with those with BCVI who remain asymptomatic. Increased angle or MA should be considered when assessing the risk of thrombosis and determining the optimal time to initiate antithrombotic therapy in patients with BCVI. LEVEL OF EVIDENCE Prognostic, Level III.

What Causes LVAD-Associated Ischemic Stroke? Surgery, Pump Thrombosis, Antithrombotics, and Infection
Acute ischemic stroke (AIS) is a major complication in left ventricular assist device (LVAD) population. A better understanding of clinical risk factors associated with AIS may help mitigate risk of stroke. We reviewed prospectively collected data of 477 LVAD patients from a tertiary center from October 1, 2004 to December 31, 2016. Supplemental data abstraction was performed on patients with AIS. Fifty-seven (12%) developed 61 AIS. Of 61, 17 (28%) AIS occurred perioperatively. The median time from implant to perioperative AIS was 5 days (interquartile range: 3–9). Pump thrombosis accounted for 19 (31%) of 61 AIS, and 7 ...
