Device used to close small hole in heart may protect against recurrent stroke
A device used to close a small hole in the heart may benefit certain stroke patients by providing an extra layer of protection for those facing years of ongoing stroke risk, according to the results of a large clinical trial led by UCLA researchers.“It is a major new treatment option for some people,” said Dr. Jeffrey Saver, director of theUCLA Comprehensive Stroke Center and lead author of the study. However, he added, “Using the device is going to have to be a considered clinical decision between the doctor and the patient about who’s the right person to get it.”Thefindings appear in the Sept. 14 New England Jo...

Publication date: Available online 26 February 2018 Source:The Lancet Global Health Author(s): Mayowa O Owolabi, Fred Sarfo, Rufus Akinyemi, Mulugeta Gebregziabher, Onoja Akpa, Albert Akpalu, Kolawole Wahab, Reginald Obiako, Lukman Owolabi, Bruce Ovbiagele Background Sub-Saharan Africa has the highest incidence, prevalence, and fatality from stroke globally. Yet, only little information about context-specific risk factors for prioritising interventions to reduce the stroke burden in sub-Saharan Africa is available. We aimed to identify and characterise the effect of the top modifiable risk factors for stroke in sub-Sahara...

Efficacy of nitric oxide, with or without continuing antihypertensive treatment, for management of high blood pressure in acute stroke (ENOS): a partial-factorial randomised controlled trial
This study is registered, number ISRCTN99414122. Findings Between July 20, 2001, and Oct 14, 2013, we enrolled 4011 patients. Mean blood pressure was 167 (SD 19) mm Hg/90 (13) mm Hg at baseline (median 26 h [16–37] after stroke onset), and was significantly reduced on day 1 in 2000 patients allocated to glyceryl trinitrate compared with 2011 controls (difference −7·0 [95% CI −8·5 to −5·6] mm Hg/–3·5 [–4·4 to −2·6] mm Hg; both p<0·0001), and on day 7 in 1053 patients allocated to continue antihypertensive drugs compared with 1044 patients randomised to stop them (difference −9·5 [95% CI −11...

Incidence, outcome, risk factors, and long-term prognosis of cryptogenic transient ischaemic attack and ischaemic stroke: a population-based study
Publication date: Available online 27 July 2015 Source:The Lancet Neurology Author(s): Linxin Li, Gabriel S Yiin, Olivia C Geraghty, Ursula G Schulz, Wilhelm Kuker, Ziyah Mehta, Peter M Rothwell Background A third of transient ischaemic attacks (TIAs) and ischaemic strokes are of undetermined cause (ie, cryptogenic), potentially undermining secondary prevention. If these events are due to occult atheroma, the risk-factor profile and coronary prognosis should resemble that of overt large artery events. If they have a cardioembolic cause, the risk of future cardioembolic events should be increased. We aimed to asses...

Statistical analysis plan for the ‘Efficacy of Nitric Oxide in Stroke’ (ENOS) trial
High blood pressure is common during the acute phase of stroke and is associated with a poor outcome. However, the management of high blood pressure remains unclear. The ‘Efficacy of Nitric Oxide in Stroke’ trial tested whether transdermal glyceryl trinitrate, a nitric oxide donor that lowers blood pressure, is safe and effective in improving outcome after acute stroke. Efficacy of Nitric Oxide in Stroke is an international multicenter, prospective, randomized, single‐blind, blinded endpoint trial, with funding from the UK Medical Research Council. Patients with acute ischemic stroke or intracerebral hemorrhage and s...

Effect of atherosclerosis on 5-year risk of major vascular events in patients with transient ischaemic attack or minor ischaemic stroke: an international prospective cohort study
Lancet Neurol. 2023 Apr;22(4):320-329. doi: 10.1016/S1474-4422(23)00067-4.ABSTRACTBACKGROUND: The prevalence of atherosclerosis and the long-term risk of major vascular events in people who have had a transient ischaemic attack or minor ischaemic stroke, regardless of the causal relationship between the index event and atherosclerosis, are not well known. In this analysis, we applied the ASCOD (atherosclerosis, small vessel disease, cardiac pathology, other causes, and dissection) grading system to estimate the 5-year risk of major vascular events according to whether there was a causal relationship between atherosclerosis...

Rapid intervention with glyceryl trinitrate in hypertensive stroke trial-2 (right-2): safety and efficacy of transdermal glyceryl trinitrate, a nitric oxide donor
Rationale High blood pressure (BP) is common in acute stroke and is associated with poor outcome. Previous hospital-based trials testing the effects of BP lowering on functional outcome have been inconclusive. The PIL-FAST and RIGHT pilot trials confirmed the feasibility of performing single-centre ambulance-based stroke trials in the UK. In both RIGHT and a subgroup of patients recruited within 6 hours into the large ENOS trial, transdermal glyceryl trinitrate (GTN), a nitric oxide donor, lowered BP and reduced death or disability. Based on these results, RIGHT-2 aims to test the safety and efficacy of transdermal GTN in ...

Defective trophoblast invasion underlies fetal growth restriction and preeclampsia-like symptoms in the stroke-prone spontaneously hypertensive rat
AbstractSTUDY QUESTIONWhat is the impact of chronic hypertension on placental development, fetal growth and maternal outcome in the stroke-prone spontaneously hypertensive rat (SHRSP)?SUMMARY ANSWERSHRSP showed an impaired remodeling of the spiral arteries and abnormal pattern of trophoblast invasion during placentation, which were associated with subsequent maternal glomerular injury and increased baseline hypertension as well as placental insufficiency and asymmetric fetal growth restriction (FGR).WHAT IS KNOWN ALREADYA hallmark in the pathogenesis of preeclampsia (PE) is abnormal placentation with defective remodeling o...

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Real-World Study Confirms Benefit of XARELTO ® (rivaroxaban) for Secondary Prevention of Venous Thromboembolism in Cancer Patients
TITUSVILLE, NJ, December 9, 2022 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced observational data from eight years of clinical practice showing that the oral Factor Xa inhibitor XARELTO® (rivaroxaban) is associated with comparable effectiveness and safety to the Factor Xa inhibitor apixaban for the treatment of cancer-associated thromboembolism (CAT) in a broad cohort of patients with various cancer types. Patients with CAT are at a higher risk of venous thromboembolism (VTE), which is the second-leading cause of death in people with cancer.1Data from the Observational Study in Cancer-A...
