OBJECTIVE Poststroke hyperglycemia is common and is associated with increased risk of death and dependence, but appropriate management remains uncertain. Glucose potassium insulin (GKI) infusion did not benefit patients with moderate poststroke hyperglycemia in a recent trial. Using magnetic resonance imaging (MRI), previous studies identified a(More)
BACKGROUND Three peptides consisting of amino acids 1-30, 31-67, and 79-98 of the 126-amino acid atrial natriuretic factor prohormone (proANF), which have blood pressure-lowering, diuretic, natriuretic, and/or kaliuretic properties in animals, were investigated to determine if they have similar properties in humans. METHODS AND RESULTS Thirty-six healthy,(More)
BACKGROUND Intravenous alteplase is licensed for treatment of ischaemic stroke within 3 h of onset. Up to one-third of patients in the UK present to hospital within this time window but few are treated. AIMS To examine the effect of a stroke thrombolysis protocol on service provision for an acute stroke service in the UK, jointly run by Neurology and(More)
BACKGROUND Vessel dilator, a 37-amino acid peptide hormone synthesized in the heart, enhances urine flow 4- to 12-fold and sodium excretion 3- to 6-fold in healthy humans. The present investigation was designed to determine whether vessel dilator might have similar beneficial effects in persons with congestive heart failure (CHF). METHODS AND RESULTS(More)
BACKGROUND AND PURPOSE European directives and legislation in some countries forbid inclusion of subjects incapable of consent in research if recruitment of patients capable of consent will yield similar results. We compared brain lesion volumes in stroke patients deemed to have capacity to consent with those defined as incapacitated. METHODS Data were(More)
Current acute therapies for ischemic stroke are limited. Only a small proportion of stroke patients are eligible to receive fibrinolytic therapy; clinical trials of neuroprotectant drugs have yielded disappointing results, and other potential interventions are at very early stages of development. Against this background, coordinated stroke unit care is,(More)
BACKGROUND AND PURPOSE Early ischemic changes on noncontrast CT in acute stroke include both hypoattenuation and brain swelling, which may have different pathophysiological significance. METHODS Noncontrast CT and CT perfusion brain scans from patients with suspected acute stroke <6 hours after onset were reviewed. Five raters independently scored(More)
The present investigation was designed to determine whether atrial natriuretic peptides consisting of amino acids 1-30 [i.e. pro-ANF-(1-30)], 31-67 [i.e. pro-ANF(31-67)], 79-98 [i.e. pro-ANF-(79-98)], and 99-126 [i.e. atrial natriuretic factor (ANF)] of 126-amino acid ANF prohormone have a negative feedback on their own and each others' release. Thirty(More)
BACKGROUND Post-stroke hyperglycaemia (PSH) is associated with higher mortality and dependence, but further data on predictors of PSH and its evolution over time are required. We examined the prevalence, predictors, and prognosis of acute PSH using data from well-characterised clinical trials in the VISTA database. METHODS Data were extracted for(More)
