Filter by:Acute lymphoblastic leukemia (ALL) is the most common malignant disease in childhood. Today more than 90% of children and 75% of adults (18-45 years) survive ALL. The enzyme Asparaginase (Asp) is an indispensable part of the multiagent treatment of ALL. Treatment related severe acute toxicities are common. Especially in teenagers and adults, thromboembolism is one of the most common acute toxicities and may result in post thrombotic syndrome (PTS) or pulmonary hypertension. The knowledge about these late effects is limited, including for ALL patients.
Venous thromboembolism (VTE - blood clots that form in deep veins or in the lungs) has been identified as a leading cause of death in economically developed countries for pregnant and recently-pregnant women. There is evidence that clotting parameters can take up to 6 weeks to return to normal for women who have had term deliveries, however there is an absence of information on time taken for clotting parameters to normalise following abortion. As such, existing guidelines are based solely on expert opinion and recommend durations of VTE prevention from as short as 7 days, up to 6 weeks following abortion. All women are assessed for risk of VTE, but data are needed to inform an evidence-based approach to prevention of VTE in these women. The findings from this pilot study have the potential to inform clinical guidance and possibly a larger study subsequently.
Pulmonary embolism (PE) is a common pathology causing significant morbidity and mortality. It is usually secondary to migration through the inferior vena cava (IVC) of a formed thrombus in the veins of the lower limbs or pelvis. The inferior vena cava filter (IVCF) is a medical device whose purpose is to prevent thrombus migration from the veins of the legs and pelvis to the pulmonary arteries, thus preventing the occurrence of Pulmonary embolism (PE). There is no data on the interactions of Retrievable inferior vena cava filters (IVCF) with the inferior vena cava (intrafilter thrombi, insertion through the venous wall) although it may modify the evolution after IVCF retrievable.
This online-based, observational retrospective registry aims to (i) study the rate of cardiovascular events, encompassing venous thromboembolic and arterial events, in consecutive hospitalized patients with coronavirus (Covid19), (ii) investigate the prevalent use of thromboprophylaxis, (iii) describe the use of imaging tests for the detection of cardiovascular events in patients with Covid19. This will also facilitate and constitute the basis for the conduction of interventional thromboprophylaxis studies in patients with Covid19.
In our study, investigators will investigate the effectiveness and complications of two catheter lock solutions one of which is the standard heparin routinely used in comparison to Sodium bicarbonate. Both solutions were used but not compared head to head. Investigators aim to compare both solutions in terms of catheter lumen patency and their effect on catheter-related infections.
In patients with hgepatocellular carcinoma (HCC) and portal vein tumoral thrombosis (PVTT), Sorafenib represents the treatment of choice but more recently, trans-arterial radioembolization (TARE) with yttrium-90 has been also proposed. A considerable percentage of such patients are not only able to achieve stability of the disease, but also to obtain a complete radiological response (CR). The possibility of achieving a CR might allow these patients to be listed for liver transplantation (LT), in order to cure not only the cancer but also the underlying cirrhosis that generated it.
Catheter-related thrombosis could impair blood flow in the vein, block the central venous catheter, induce catheter-related infection or venous thromboembolism in the deep veins or pulmonary vessels, which furthermore progress into the post-thrombotic syndrome. Researches using echogenic mass as the primary outcome could miss those premature thrombi which might not be seen on traditional ultrasonography but may be detected by Duplex and Doppler ultrasound with vessel compression. Moreover, studies indicated that some thrombus developed after the catheter removal. Removal of the catheter is not the endpoint of thrombus detection. This study is designed to determine the preventive effects of continuous heparin infusion on real-world central venous catheter-related thrombosis in infants after cardiac surgery.
The PTRG-DES consortium is a coalition composed of multi-center, real-world registries including CAD patients treated with DES in South Korea. From 9 academic registries in Korea, a total of 13,160 patients were enrolled for this database between July 2003 and August 2018. The aim of the study was to investigate long-term prognostic implications of platelet function and genotypes after DES implantation for significant CAD in South Korea.
The main objective is to evaluate the efficacy and safety of three doses of tinzaparin (prophylactic, intermediate and therapeutic) in hospitalized patients with COVID-19 pneumonia.
Rationale Many patients with coronavirus disease (COVID-19) need hospital admission for oxygen supplementation. A substantial number of patients need intensive care unit (ICU) admission for escalation of care. ICU doctors and nurses are struggling to provide the best care for patients with COVID-19. Practice of adjunctive and supportive treatments remains uncertain. Objective To determine and compare practice of adjunctive and supportive treatments for COVID-19 in the Netherlands, and to determine their independent associations with outcome. Hypotheses Practice of adjunctive and supportive treatments for COVID-19 varies substantially. Adjunctive and supportive treatments have an independent association with outcome in ICU patients with COVID-19. Study design National/international, multicenter, retrospective observational study. Study population Intensive care unit (ICU) patients with COVID-19. Methods In this study we will collect data on diverse treatments during the first 28 days in ICU, including (a) the types of oxygen support* and awake prone positioning; (b) the types of ventilatory support, (c) rescue therapies for refractory hypoxemia during invasive ventilation (prone positioning, ventilator adjustments, continuous muscle paralysis, and extracorporeal membrane oxygenation); (d) adjunctive treatments, including thromboprophylaxis and anticoagulation, antiviral and immunomodulating therapies, and (e) experimental supportive treatments. Outcomes include duration of each adjunctive treatment, duration of ventilation, incidence of tracheostomy, duration of stay in ICU and mortality until day 90. Study endpoints A combination of adjunctive treatments, including types of oxygen support, ventilatory support and rescue therapies for refractory hypoxemia during invasive ventilation (primary), other adjunctive and supportive treatments, tracheostomy rate; duration of ventilation and ventilator-free days and alive at day 28 (VFD-28), duration of ICU and hospital stay, and ICU, hospital and 90-day mortality. Nature and extent of the burden and risks associated with participation, benefit and group relatedness Retrospective collection of data regarding adjunctive treatments, and clinical endpoints is without risk for ICU patients. *In a subset of patients we will collect granular data (every two hours) regarding oxygenation (FiO2, inspiratory tidal volume, air flow, respiratory rate, SpO2, PaO2, and PEEP) over the first 2 full calendar days of ICU admission. The primary endpoint of this sub-analysis will be the amount of oxygen used with different respiratory support interventions. The statistical analysis plan for the analysis of these data that were collected in two ICUs that participated in the national study, and one additional ICU in Spain is uploaded in the document section (filename Statistical Analysis Plan PROXY-COVID)
