Background and purpose: Although poor prognosis after intracerebral haemorrhage relates to risk factors and haematoma characteristics, there is limited evidence for the effect of race-ethnicity. Methods: Data from 1011 patients with intracerebral ha...

Assessment of consent models as an ethical consideration in the conduct of prehospital ambulance randomised controlled clinical trials: a systematic review (2017)
Journal Article
Background We sought to understand the main ethical considerations when conducting clinical trials in the prehospital ambulance based setting. Methods A systematic review of the literature on randomised controlled trials in ambulance setting...

Rationale The pathophysiology of most lacunar stroke, a form of small vessel disease, is thought to differ from large artery atherothrombo- or cardio-embolic stroke. Licensed drugs, isosorbide mononitrate and cilostazol, have promising mechanisms... Read More about Preventing cognitive decline and dementia from cerebral small vessel disease: The LACI-1 Trial. Protocol and statistical analysis plan of a phase IIa dose escalation trial testing tolerability, safety and effect on intermediary endpoints of isosorbide mononitrate and cilostazol, separately and in combination.
Background Endpoints that are commonly used in trials of moderate/severe stroke may be less frequent in patients with minor, non-disabling stroke thus inflating sample sizes. We tested whether trial efficiency might be improved with composite endp... Read More about The effect of different combinations of vascular, dependency and cognitive endpoints on the sample size required to detect a treatment effect in trials of treatments to improve outcome after lacunar and non-lacunar ischaemic stroke.
Validating and comparing stroke prognosis scales (2017)
Journal Article
Objective: To compare the prognostic accuracy of various acute stroke prognostic scales using a large, independent, clinical trials dataset. Methods: We directly compared 8 stroke prognostic scales, chosen based on focused literature review (Acute... Read More about Validating and comparing stroke prognosis scales.
Predicting major bleeding in patients with noncardioembolic stroke on antiplatelets (2017)
Journal Article
Objective: To develop and externally validate a prediction model for major bleeding in patients with a TIA or ischemic stroke on antiplatelet agents. Methods: We combined individual patient data from 6 randomized clinical trials (CAPRIE, ESPS-2, M...

Infections up to 76 days after stroke increase disability and death (2017)
Journal Article
Early infection after stroke is associated with a poor outcome. We aimed to determine whether delayed infections (up to 76 days post-stroke) are associated with poor outcome at 90 days. Data came from the international Efficacy of Nitric Oxide Stroke... Read More about Infections up to 76 days after stroke increase disability and death.
Remote assessment of platelet function in patients with acute stroke or transient ischaemic attack (2017)
Journal Article
Background: Antiplatelets reduce recurrence after cerebral ischaemia. The international TARDIS trial assessed the safety and efficacy of intensive (combined aspirin, dipyridamole and clopidogrel) versus guideline (aspirin and dipyridamole, or clopido...

Cerebral misery perfusion due to carotid occlusive disease (2017)
Journal Article
Purpose Cerebral misery perfusion (CMP) is a condition where cerebral autoregulatory capacity is exhausted, and cerebral blood supply in insufficient to meet metabolic demand. We present an educational review of this important condition, which has a... Read More about Cerebral misery perfusion due to carotid occlusive disease.
The incidence of first stroke in and around pregnancy: A population-based cohort study from Sweden (2017)
Journal Article
Introduction: Research has suggested that delivery is associated with an increased risk of stroke in women; however, there is a lack of contemporary estimates on the incidence of stroke in and after pregnancy compared with the baseline risk in women...

The incidence of first stroke in pregnant and non-pregnant women of childbearing age: a population-based cohort study from England (2017)
Journal Article
Background: Pregnant women may have an increased risk of stroke compared to non-pregnant women of similar age, but the magnitude and the timing of such risk are unclear. We examined the risk of first stroke event in women of childbearing age and comp...

Nitric oxide donors (nitrates), L-arginine, or nitric oxide synthase inhibitors for acute stroke (2017)
Journal Article
Background:Nitric oxide (NO) has multiple effects that may be beneficial in acute stroke, including lowering blood pressure, and promoting reperfusion and cytoprotection. Some forms of nitric oxide synthase inhibition (NOS-I) may also be beneficial.... Read More about Nitric oxide donors (nitrates), L-arginine, or nitric oxide synthase inhibitors for acute stroke.
Magnetic resonance imaging plaque hemorrhage for risk stratification in carotid artery disease with moderate risk under current medical therapy (2017)
Journal Article
Background and Purpose—Magnetic resonance imaging (MRI)–defined carotid plaque hemorrhage (MRIPH) can predict recurrent cerebrovascular ischemic events in severe symptomatic carotid stenosis. It is less clear whether MRIPH can improve risk stratifica... Read More about Magnetic resonance imaging plaque hemorrhage for risk stratification in carotid artery disease with moderate risk under current medical therapy.
Investigating the effect of independent blinded digital image assessment on the STOP GAP trial (2017)
Journal Article
Background Blinding is the process of keeping treatment assignment hidden and is used to minimise the possibility of bias. Trials at high risk of bias have been shown to report larger treatment effects than low risk studies. In dermatology, one popu... Read More about Investigating the effect of independent blinded digital image assessment on the STOP GAP trial.
Background Stroke is associated with the development of cognitive impairment and dementia. We assessed the effect of intensive blood pressure (BP) and/or lipid lowering on cognitive outcomes in patients with recent stroke in a pilot trial. Meth...

Understanding the relationship between costs and the modified Rankin Scale: a systematic review, multidisciplinary consensus and recommendations for future studies (2016)
Journal Article
Background and purpose: Cost-of-illness studies often describe a single aggregate cost of a disease state. This approach is less helpful for a condition with a spectrum of outcomes like stroke. The modified Rankin Scale is the most commonly used outc...

Dependency and health utilities in stroke: data to inform cost-effectiveness analyses (2016)
Journal Article
Introduction: Health utilities (HU) assign preference weights to specific health states and are required for costeffectiveness analyses. Existing HU for stroke inadequately reflect the spectrum of post-stroke disability. Using international stroke tr...

Antiplatelet therapy following ischaemic stroke: continue or change pre-existing therapy? (2016)
Journal Article
Introduction: Antiplatelet therapy is routinely prescribed early after ischaemic stroke. Many patients will already be taking antiplatelet therapy and it is unknown whether these patients should continue the same antiplatelet treatment or switch to a...

Baseline characteristics of the 3,096 patients recruited into the 'Triple Antiplatelets for Reducing Dependency after Ischaemic Stroke' (TARDIS) trial (2016)
Journal Article
Background: The risk of recurrence following ischaemic stroke (IS) or transient ischaemic attack (TIA) is highest immediately after the event. Antiplatelet agents are effective in reducing the risk of recurrence and two agents are superior to one in...

Rationale: Ongoing dysphagia in stroke patients weaned from mechanical ventilation often requires long-term tracheotomy to protect the airway from aspiration. In a recently reported single-centre pilot study, a significantly larger proportion (75%) o...
