INTRODUCTION: Reporting of sex and gender analysis in medical research has been shown to improve quality of the science and ensures findings are applicable to women and men. There is conflicting evidence on whether efforts by funding agencies and medical journals to encourage reporting of sex and gender analysis has resulted in tangible improvements. This study mapped the inclusion of sex and gender analysis in stroke and dementia research conducted in the Asia-Pacific region. METHODS: A systematic search for Asia-Pacific stroke and dementia research was conducted in PubMed and papers included from the period 2012 to 2022...

BACKGROUND: Although guidelines recommend a target blood pressure 185-180/105-110 mmHg after mechanical thrombectomy for acute ischemic stroke (AIS), there is limited randomized evidence to support this level. We surveyed candidate institutions about the approach to blood pressure management in this patient group in preparation for inviting them to participate in the Enhanced Blood Pressure Control after Endovascular Thrombectomy for the Acute Ischemic Stroke Trial (ENCHANTED2/MT). METHODS: Physicians from a professional network of institutions that met mechanical thrombectomy qualification requirements were invited to participate in an online questionnaire covering basic clinical information as well as questions on blood pressure management...

BACKGROUND: The use of Alteplase (ALT) bridging to endovascular mechanical thrombectomy (MT) has become the standard approach in treating patients with large vessel stroke (LVO). Tenecteplase (TNK) has emerged as an equivalent fibrinolytic agent in treating ischemic stroke due to its remarkable pharmacological characteristics. This study aims to compare the use of intravenous TNK to ALT bridging to MT in patients with LVO. METHODS: We included observational and randomized controlled trials of patients with LVO who received bridging TNK vs ALT before undergoing MT...

INTRODUCTION: Post-thrombectomy intraparenchymal hyperdense (PTIH) in patients with acute ischaemic stroke (AIS) is a common CT sign, making it difficult for physicians to distinguish intracerebral hemorrhage in the early post-thrombectomy period. The aim of this study is to develop an effective model to differentiate intracerebral hemorrhage from contrast extravasation in patients with PTIH. METHODS: We retrospectively collected information on patients who underwent endovascular thrombectomy (EVT) at two stroke centers between August 2017 and January 2023...

INTRODUCTION: Cerebral perforating arteries provide blood supply to the deep regions of the brain. Recently, it became possible to measure blood flow velocity and pulsatility in these small arteries. It is unknown if vascular risk factors are related to these measures. METHODS: We measured perforating artery flow with 2D phase contrast 7 Tesla MRI at the level of the centrum semiovale (CSO) and the basal ganglia (BG) in seventy participants from the Heart Brain Connection study with carotid occlusive disease (COD), vascular cognitive impairment (VCI), or no actual cerebrovascular disease...

INTRODUCTION: While patients who experience improved cognition following carotid endarterectomy (CEA) typically demonstrate restored brain perfusion after the procedure, it is worth noting that less than 50% of patients in whom postoperative cerebral blood flow (CBF) restoration is achieved actually show improved cognition after postoperatively. This suggests that factors beyond the mere restoration of CBF may play a role in postoperative cognitive improvement. Increased iron deposition in the cerebral cortex may cause neural damage, and quantitative susceptibility mapping (QSM) obtained using magnetic resonance imaging (MRI) quantifies magnetic susceptibility in the cerebral cortex, allowing for the assessment of iron deposition in vivo...

INTRODUCTION: Calcifications of the intracranial internal carotid artery (iICA) can lead to an increased risk for stroke. Two types of iICA calcification are known: those affecting the tunica intima or the tunica media. In extracranial arteries, risk factors and calcification patterns are different in women and men, but little is known regarding the iICA. In this study we aimed to identify sex-specific risk profiles and medications associated to intimal and medial iICA calcification in patients with cardiovascular disease (CVD)...
