Benefit of Machine Learning to Diagnose Deep Vein Thrombosis Compared to Gold Standard Ultrasound...
Deep Venous Thrombosis of LegDeep Vein ThrombosisThe study coordinator aims to compare gold standard deep vein thrombosis (DVT) diagnostic performed by a specialist sonographer to a scan by a non-specialist with a newly developed an automated DVT (AutoDVT) detection software device. The title of the project is: Benefit of Machine learning to diagnose Deep Vein thrombosis compared to gold standard Ultrasound. Currently the process from the DVT symptom begin, to diagnosis and then treatment is all but not straightforward. It implements a laborious journey for the patient from their general practitioner (GP) to accident and emergency (A&E), then to a specialist sonographer. However, handheld Ultrasound devices have recently become available and they have been implemented with a machine learning software. The startup company ThinkSono developed a software which is hoped to divide between thrombosis and no thrombosis. In this single-blinded pilot study, patients which present at St Mary's DVT Clinic will be scanned by the specialist and then by a non-specialist with the machine learning supported device. The accuracy and sensitivity of this device will be compared to the gold standard. This would mean that DVT could be diagnosed at point of care by a non-specialist such as a community nurse or nursing home nurse, for example beneficial for multimorbid confused nursing home patients. This technology could reduce A&E crowding and free up specialist sonographer to focus on other clinical tasks. These improvements could significantly reduce the financial burden for the National Health System (NHS). The AutoDVT has a CE (as the logo CЄ, which means that the manufacturer or importer affirms the good's conformity with European health, safety, and environmental protection standards) Certificate under the directive 93/42/ European Economic Community (EEC) for medical devices. It is classified in Class 1 - Active Medical Device - Ultrasound Imaging System Application Software (40873). Furthermore, following standards and technical specifications have been applied: British Standard (BS) European Norm (EN) International Organisation for Standardisation (ISO) 13485:2016, BS EN ISO 14971:2012, Data Coordination Board (DCB)0129:2018, ISO 15233-1:2016.
Prevalence of Asymptomatic Thrombosis in Multiple Myeloma
ThrombosisMultiple MyelomaMalignant hemopathies, such as solid cancers, increase the risk of venous and arterial thromboembolic events. The incidence of symptomatic venous thromboembolic events is particularly high in myeloma, linked to the usual risk factors for venous thromboembolic disease, biological risk factors specific to myeloma, and especially to its treatments. The prevalence of asymptomatic venous thromboembolic events and arterial events are not known to date and remain important data for planning a possible randomized study to determine the most suitable thromboprophylaxis in these patients.

Evaluation of Cerebral Oxygenation and Hemodynamics in Patients With Cerebral Venous Thrombosis...
Cerebral Venous ThrombosisCerebral hypoperfusion and hypoxia are the major determinants of neurological outcomes following acute brain injury as proved in Traumatic Brain Injury/Sub Arachnoid Haemhorrhage literature. How the brain injury affects cerebral oxygenation in patients with CVT is not currently known. Some of the factors that can affect cerebral oxygenation in patients with CVT are Hemoglobin, PO2, PCO2, Cerebral Perfusion Pressure (or MAP) and change in Intracranial Pressure after Decompressive Craniectomy. This study is designed to study how these factors affect cerebral oxygenation and impact of Decompressive Craniectomy on the cerebral oxygenation.

InfertilityHyperstimulation Syndrome2 moreIntroduction: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic phenomenon, poorly understood and difficult to predict, complicating intense ovarian stimulation cycle. The most severe symptoms, which associate vascular permeability disorders and hypercoagulability, occur in 0.2 to 1% of the cases and often require intensive care. Activation of endothelial, platelet, erythrocyte or leukocyte cells trigger the release of small specific vesicles, called microparticles, used as markers. Classically leading to endothelial dysfunction and hypercoagulability, the endothelial activation phenomenon could constitute the main cause of OHSS or help predict its severity, as established for various other diseases (cerebral stroke, infarct and lupus…). However, so far, this endothelial activation role has never been studied. Objectives: Evaluate the serum level of microparticles as a predictor of adverse outcomes; correlate it to hypercoagulability and changes of endothelial permeability associated with this syndrome. Methodology: Prospective Pilote Cohort study, evaluating before and throughout the ovarian stimulation cycle (6 samples/patient), the serum modulation of: Endothelial activation markers (endothelial-derived microparticles, E-selectin) Procoagulant markers (microparticles from platelet, erythrocyte or leukocyte origin, Von Willbrand factor, thrombin-antithrombin complex, prothrombin fragment 1+2) Endothelial disjunction marker (soluble CD 146) A group of 50 patients will be assessed Techniques: Flow cytometry for measurement of microparticles expressing non specific (Annexin V) and cell specific surface determinants (CD 31, CD 41, CD 45 or glycophorin A). Use of commercial kits for other serum markers.

Stroke and Cerebrovascular Diseases Registry
StrokeAcute Stroke10 moreThis is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.
