Although the association between cerebral amyloid angiopathy (CAA) and cognitive impairment is increasingly recognized, it not clear whether this because of impact recurrent intracerebral hemorrhage (ICH) events, disruptions caused by small vessel damage, or both. We investigated considering before ICH was associated with neuroimaging features CAA on magnetic resonance imaging.We studied 166 patients neuroimaging-confirmed recruited to a prospective multicentre observational study....
The New Zealand (NZ) Central Region Stroke Network, serving 1.17 million catchment population, changed to tenecteplase for stroke thrombolysis in 2020 but was forced revert Alteplase 2021 due a sudden cessation of drug supply. We used this unique opportunity assess potential before and after temporal trend confounding.In NZ all reperfused patients are entered prospectively into national database safety monitoring. assessed patient outcomes treatment metrics over three time periods: alteplase...
Stroke is the second leading cause of death worldwide, with highest mortality rates in low- to middle-income countries, particularly sub-Saharan Africa. We aimed investigate predictors 30-day among patients stroke admitted at a tertiary teaching hospital Northwestern Tanzania.This cohort study recruited World Health Organization's clinical definition stroke. Data were collected on baseline characteristics, degree neurological impairment admission (measured using National Institutes Scale),...
To investigate whether enlarged perivascular spaces (PVS) within the basal ganglia or deep cerebral white matter are risk factors for intracranial hemorrhage in patients taking oral anticoagulants (OACs), independent of established clinical and radiologic factors, we conducted a post hoc analysis Clinical Relevance Microbleeds Stroke (CROMIS-2) (atrial fibrillation [AF]), prospective inception cohort study.Patients with atrial recent TIA ischemic stroke underwent standardized MRI prior to...
Introduction: Hematoma expansion (HE) is strongly associated with mortality and disability in intracerebral hemorrhage (ICH). While it accepted that the majority of this occurs early after onset, there limited data on HE associations outcome ultra-early time window (within 3 hours symptom onset). We aimed to (a) estimate incidence within period ICH, (b) describe hematoma growth dynamics over time, (c) investigate between clinical outcomes ICH. Methods: performed a planned secondary analysis...
Background The most frequent electrolyte derangement in adults with stroke is hyponatremia, which associated increased morbidity, mortality, and prolonged hospital stay. study aimed to investigate the hyponatremia incidence 30-day outcomes among admitted at a large tertiary teaching Northwestern Tanzania. Methods This cohort recruited presenting first-ever (as defined by World Health Organization) between November 2023 May 2024. Data were collected on demographics, degree of neurological...
Background: Atrial fibrillation (AF) increases ischaemic stroke (IS) risk, which can be mitigated using risk prediction models to guide anticoagulation decisions. This resultant widespread use of anticoagulants has reduced IS rates globally. However, commonly used scores were validated in mainly European cohorts. Cardiology society guidelines recommend the local refinement such improve prediction. study aims: 1. To determine trends prevalence AF associated Auckland. 2. perform a validation...
We present the case of a 55-year-old Caucasian man presenting with polyarthritis, weight loss and multiple tender cutaneous nodules. Abnormal liver function tests prompted imaging which demonstrated metastases. Biopsy lesions confirmed diagnosis metastatic pancreatic neuroendocrine carcinoma.
Background It is likely that a proportion of poststroke cognitive impairment sometimes attributable to unidentified prestroke decline; function also clinically relevant because it associated with poor functional outcomes, including death. We investigated the radiological and prognostic associations preexisting in patients ischemic stroke or transient attack atrial fibrillation. Methods Results included 1102 from prospective multicenter observational CROMIS ‐2 (Clinical Relevance Microbleeds...
Rationale Haematoma growth is common early after intracerebral haemorrhage (ICH), and a key determinant of outcome. Tranexamic acid, widely available antifibrinolytic agent with an excellent safety profile, may reduce haematoma growth. Methods design Stopping tranexamic acid for hyperacute onset presentation including mobile stroke units (STOP-MSU) phase II double-blind, randomised, placebo-controlled, multicentre, international investigator-led clinical trial, conducted within the estimand...
Background: Most strokes and cardiovascular diseases (CVDs) are potentially preventable if their risk factors identified well controlled. Digital platforms, such as the PreventS-MD web app (PreventS-MD) may aid health care professionals (HCPs) in assessing managing promoting lifestyle changes for patients. Methods: This is a mixed-methods cross-sectional two-phase survey using largely positivist (quantitative qualitative) framework. During Phase 1, prototype of was tested internationally by...
