Filter by:Covid-19 mainly affects the respiratory system. Multiple organ dysfunction and a particularly progressive respiratory insufficiency along with a widespread coagulopathy presumed to be due to infection-associated inflammation and the resulting cytokine storm, are strongly associated with high mortality rates. In this study, the association between thrombosis risk and clinical presentation of Covid-19 is investigated.
Venous thromboembolic disease is a significant cause of morbidity and mortality. The purpose of the RAPID registry is to collect information on the Angiovac procedure and Angiovac device used in the treatment of deep venous thrombosis (DVT), right heart pathology and pulmonary embolism.
The researchers wanted to learn how to help sick patients who are in the hospital because of COVID-19. They are trying to find out the best way that is safe to stop blood clots that could be dangerous from forming in patients with COVID-19. This research study happened at 34 hospitals. All patients in the study took medicines that help prevent blood clots. These medicines are called blood thinners or anticoagulants. Patients got different amounts of blood thinners to see what works better and is safer. Researchers randomly chose some patients to get more and some to get less. The researchers also wanted to know if another medicine called clopidogrel can safely help stop blood clots from forming. This kind of medicine helps keep parts of the blood, called platelets, from sticking together. In some patients who did not have other reasons to take a platelet-blocker the researchers randomly chose the patient to take clopidogrel or not. This type of medicine is also called an antiplatelet.
The purpose of this study is to investigate the prevalence of venous thromboembolism in a regional health care system (Region Östergötland, Sweden) before and during the SARS-COV-2 pandemic. In a retrospective observational study, we will review patient data, diagnostic data and treatment data over a three-month period since the onset of the SARS-COV-2 pandemic. This data will be compared with data from the corresponding time frame during the years 2015 to 2019.

Research subgroup According to the order of the patients, the following groups are entered in turn, and the cycle is repeated. 1. ) Heparin group 2. ) Rivaroxaban group 3. ) Control group.
To improve the safety of diagnosis and therapy for a set of conditions and undifferentiated symptoms for hospitalized patients, the investigators will employ a set of methods and tools from the disciplines of systems engineering, human factors, quality improvement,and data analytics to thoroughly analyze the problem, design and develop potential solutions that leverage existing current technological infrastructure, and implement and evaluate the final interventions. The investigators will engage the interdisciplinary care team and patient (or their caregivers) to ensure treatment trajectories match the anticipated course for working diagnoses (or symptoms), and whether they are in line with patient and clinician expectations. The investigators will use an Interrupted time series (ITS) design to assess impact on diagnostic errors that lead to patient harm. The investigators will perform quantitative and qualitative evaluations using implementation science principles to understand if the interventions worked, and why or why not.
Although the use of peripheral venous catheters (CVP) with brachial insertion with echo-guide (Midline) has increased significantly over the last 5-10 years, there are no sensitive data concerning complications in the literature during their use, particularly as regards incidence of thrombotic complication.The prospective observational study will enroll all the patients admitted to Home Health Hospitalization service, Geriatric Department and Intermediate Care service, to whom a Midline-type CVP will be placed for infusional therapy and who will give their consent to participate.
The aim of the present study is to assess clinically and radio-graphically the regenerative potential of immature permanent teeth with necrotic pulp using blood clot and Platelet rich fibrin scaffolds.
Severe COVID-19 patients at a high risk of venous thromboembolism. We studied patients in 2 intensive care units of university hospitals in Barcelona and Badalona, Spain. We performed a cut-off screening of deep venous thrombosis (DVT) with bilateral duplex ultrasound to 230 patients.
Worldwide observational studies indicate a significant prothrombogenic effect associated with SARS-CoV-2 infection with a high incidence of venous thromboembolism (VTE), notably life-threatening pulmonary embolism. According to recommendations for acute medical illnesses, all COVID-19 hospitalized patients should be given VTE prophylaxis such as a low molecular weight heparin (LMWH). A standard prophylactic dose (eg. Enoxaparin 4000IU once daily) could be insufficient in obese patients and VTE has been reported in patients treated with a standard prophylactic dose. In COVID-19 patients, guidelines from several international societies confirm the existence of an hypercoagulability and the importance of thromboprophylaxis but the "optimal dose is unknown" and comparative studies are needed. In view of these elements, carrying out a trial comparing various therapeutic strategies for the prevention of VTE in hospitalized patients with COVID-19 constitutes a health emergency. Thus, we hypothesize that an increased prophylactic dose of weight-adjusted LMWH would be greater than a lower prophylactic dose of LMWH to reduce the risk of life-threatening VTE in hospitalized patients. The benefit-risk balance of this increase dose will be carefully evaluated because of bleeding complications favored by possible renal / hepatic dysfunctions, drug interactions or invasive procedures in COVID-19 patients. This multicenter randomized (1:1) open-label controlled trial will randomize hospitalized adults with COVID-19 infection to weight-adjusted prophylactic dose vs. lower prophylactic dose of LMWH.
