Filter by:Endovascular thrombectomy (EVT) is a highly effective therapy for acute ischemic stroke with large vessel occlusion (LVO). EVT was proven efficacious in selected patients with symptoms onset or last-known-well time of up to 24 hours. With a number-needed-to-treat (NNT) of 2.3-2.8 to achieve functional independence, EVT had become the current state-of-the-art treatment for ischemic stroke with LVO. Nevertheless, more than half of LVO strokes suffered from functional dependence or death despite EVT. Futile EVTs were contributed by peri-procedural malignant brain edema (MBE) and symptomatic intracranial hemorrhage (sICH). Studies suggested that 26.9% of EVTs were complicated by MBE, whereas sICH was present in 6-9% of LVO patients who received EVT. The fundamental pathophysiology of MBE and sICH is blood-brain-barrier (BBB) disruption secondary to ischemia, mechanical and reperfusion injury. These pathological processes can result in increased tissue permeability, excess production of oxygen free radicals and inflammatory response that eventually lead to hemorrhage and edema. Poor collateral circulation, proximal LVOs, intravenous thrombolysis, blood pressure and glucose fluctuation had all been implicated to in MBE and sICH. However, these risk factors were either unmodifiable or not shown to improve EVT outcomes. The preliminary results of a recent randomized trial even suggested harmful effects of intensive blood pressure following EVT. With indications of EVT are expanding to patients with prolonged ischemia and large ischemic cores, enhancing BBB and neuronal tolerance to ischemia and reperfusion therapies may hugely impact on EVT outcomes. Recent animal models have shown that glucagon-like peptide peptide-1 receptor agonists (GLP-1RA) significantly reduced infarct volume and neurological deficits following temporary or permanent middle cerebral artery occlusion. These effects were likely due to the anti-oxidant, anti-inflammatory and anti-apoptotic properties of GLP-1RA that protected BBB integrity and ischemic neurons during induced LVO and/or reperfusion. Investigator hypothesizes that compared to standard reperfusion strategies, administration of GLP-1RA in LVO patients who receive EVT may prevent the development of MBE and sICH, and improve neurological outcomes. In this randomized, open-label pilot study, investigator aims to determine the effect of semaglutide, a GLP-1RA, on the radiological and clinical outcomes in LVO patients undergoing EVT.
The goal of this clinical trial is to compare the efficacy of L-ornithine L-aspartate and Polyethylene Glycol in Cirrhotic Patients with Overt Hepatic Encephalopathy. Participants will be asked to fill out a few questions on proforma that will obtain demographic information as well as information relating to the patient's health. Treatments that they will receive after inclusion in the study, will be the standard treatment (Lactulose) along with additional medication as part of our research (LOLA or Polyethylene glycol).
Sepsis is associated with a mortality rate of 20-25%, with significant increase in case of associated comorbidities or shock. SAE is one of the most common forms of encephalopathy encountered in critically ill patients, with increased ICP as a possible underlying mechanism. Many studies revealed that ONSD is a valuable ICP monitoring tool. Also, ONSD/ETD ratio, according to previous studies, seemed to be more reliable than ONSD alone in predicting neurological outcomes of comatosed patients. The present study will assess the correlation between US-ONSD/ETD ratio and the prognosis of SAE in critically ill patients.
The objective of our study is to investigate the association of umbilical cord abnormalities with adverse pregnancy outcomes. The umbilical cord parameters that will be investigated as part of this study include the umbilical cord coiling index (UCI), umbilical cord (UC) diameter, umbilical vein (UV) diameter, UV flow velocity and the presence of nuchal cord. The UCI, UC, UV diameter & flow and presence of nuchal cord will be measured in routine unselected populations at 20-22 weeks and 35-37 weeks gestation during the study period. We will also measure the UC and UV diameter in a nested population of high-risk pregnancies attending our placental disorders clinic which have been deemed to be at risk of having adverse pregnancy outcomes. Primary objective: To investigate if prenatal assessment of UCI, UC, UV diameter & flow and presence of nuchal cord measured routinely in unselected screened populations at 20-22 weeks and 35-37 weeks' can provide an independent prediction of pregnancies that develop adverse pregnancy outcomes. Secondary objectives: To assess the correlation of UC and UV diameter measured by ultrasound scan and fetal magnetic resonance imaging in prediction of pregnancy outcome. To examine the association of these umbilical cord measurements and observations in a nested cohort of pregnancies in the high-risk placental disorders clinic.
Multicentre, prospective, Multi-arm Multi-stage (MAMS) seamless phase 2b/3 interventional randomized placebo-controlled double-blinded parallel-assignment (2 arms with 1:1 randomization) efficacy and safety trial to test intra-arterial tenecteplase at the completion of thrombectomy versus best practice in participants with anterior circulation LVO receiving mechanical thrombectomy within 24 hours of symptoms onset.
The goal of this randomised control trial is to establish the safety and efficacy of whole-body hypothermia for babies with mild hypoxic ischaemic encephalopathy, inform national and international guidelines, and establish uniform practice across the NHS. The main questions it aims to answer are: 1. Does whole-body cooling (33.5+0.5°C) initiated within six hours of birth and continued for 72 hours, improve cognitive development at 24 (±2) months of age after mild neonatal encephalopathy compared with normothermia (37+0.5°C)? 2. Does a prospective trial-based economic evaluation support the provision of cooling therapy for mild encephalopathy in the NHS on cost-effectiveness grounds? Participants will have the following interventions: - Randomisation into one of the following groups - Whole body hypothermia group - Targeted normothermia group - Bayley Scales of Infant and Toddler Development 4th Edition (Bayley-IV) examination at 24 (±2) months of age. Researchers will compare the mean Cognitive Composite Scale score from the Bayley IV examination between the two groups.
A study conducted in Finland discovered that a multidomain intervention, consisting of physical activity, nutritional guidance, cognitive training, social activities, and management of vascular risk factors, effectively decelerated cognitive decline in healthy older adults who were at an increased risk of cognitive decline. The HERITAGE study is a 2-year clustered randomized controlled trial (clustered-RCT) that explores the efficacy of a multidomain intervention among 1200 elderly residents with a higher risk of cognitive decline and dementia in Zhejiang Province, China
Sleep difficulties are common following stroke yet effective evidence-based interventions for improving sleep in this population are lacking. A small number of studies have investigated the use of music listening as a way to improve sleep in adults with insomnia. This study aims to examine whether a mindful music-listening intervention can reduce subjective and objective insomnia symptoms and improve mood and fatigue post-stroke. Six adults with a clinical diagnosis of stroke presenting with an insomnia disorder will be recruited from stroke services within NHS Greater Glasgow and Clyde. A multiple baseline single case experimental design will be employed. Participants will be randomly allocated to a baseline phase of 7, 11 or 15 days, followed by a five-week mindful music-listening intervention incorporating sleep hygiene. Changes in subjective and objective sleep will be measured using questionnaires and actigraphy, respectively. Mood and fatigue will also be measured. The data will be analysed using visual inspection, Tau-U and multi-level modelling.
Acute necrotizing encephalopathy of childhood (ANEC) is a fulminant type of encephalopathy. Most reported cases occur in Asian children with the highest prevalence among patients between the age of 6 and 18 months. The most common clinical presentations are fever, rapid alteration in the level of consciousness, and seizures, in addition to characteristic findings in brain imaging that include, but are not limited to, bilateral thalamic lesions with supra and infra-tentorial lesions of variable dimensions. The diagnosis of ANEC was determined by specific diagnostic criteria as described by Mizuguchi [1] which consist of 1. Encephalopathy preceded by viral febrile illness with rapid deterioration in the level of consciousness and convulsions. 2. Absent cerebrospinal fluid (CSF) pleocytosis. 3. Symmetric multifocal brain lesions. 4. Elevation in serum aminotransferase levels. 5. Exclusion of similar diseases. The ANE severity score was used to assess the severity of illness after admission for shock (3 points), brainstem lesions (2 points), age >4 years (2 points), platelet (PLT) count < 100,000 (1 point), and elevated CSF protein (1 point) was observed.
