Filter by:The goal of this clinical trial is to evaluate tailored duration of long-term anticoagulant treatment after a first venous thromboembolism based on individualized risk assessments of recurrent VTE and major bleeding risks. Participants will be asked to fill in a questionnaire and take a buccal swab, which are used for an individual estimation of the risks of recurrent VTE and bleeding. Based on these risks a treatment advise will be made, or randomised in a subgroup of patients.
Compression ultrasonography (CUS), which is the gold-standard for the diagnosis of deep vein thrombosis, cannot provide adequate information on the timing of the onset of thrombosis. Shear-Wave elastography, a technique used to assess tissue elasticity and widely used in hepatology, could play a crucial role in distinguishing between acute and chronic deep vein thrombosis. This study aims at evaluating the efficacy and diagnostic and prognostic accuracy of Shear-Wave elastography in distinguishing between acute and chronic deep vein thrombosis.
Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory system disease characterized by persistent respiratory symptoms and irreversible airflow restriction, which seriously endangers people's health. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) refers to individuals who experience continuous deterioration beyond their daily condition and need to change their routine medication. AECOPD is usually caused by viruses and bacteria, and patients require hospitalization, which brings a huge economic burden to society. AECOPD patients often have limited activities. Because long-term chronic hypoxia causes venous blood stasis, siltation causes secondary red blood cell increase, and blood hypercoagulability, AECOPD patients have a high risk of pulmonary embolism (PE). Pulmonary Thrombo Embolism (PTE) refers to a disease caused by blockage of the pulmonary artery or its branches caused by a thrombus from the venous system or right heart. AECOPD patients experience elevated hemoglobin levels and increased blood viscosity due to long-term hypoxia. At the same time, such patients have decreased activity, venous congestion, and are prone to thrombosis. After the thrombus falls off, it can travel up the vein, causing PTE to occur in the right heart PTE is often secondary to low deep vein thrombosis (DVT). About 70% of patients were diagnosed as deep vein thrombosis in lower limb color ultrasound examination. SteinPD conducted a survey on COPD patients and general patients from multiple hospitals. The results showed that by comparing adult COPD patients with non COPD patients, the relative risk of DVT was 1.30, providing evidence for AECOPD being more likely to combine with PTE AECOPD patients with PTE have similarities in their clinical manifestations. It is difficult to distinguish between the two based solely on symptoms, such as cough, increased sputum production, increased shortness of breath, and difficulty breathing. They lack specificity and are difficult to distinguish between the two based solely on symptoms, which can easily lead to missed diagnosis. CT pulmonary angiography (CTPA) is the gold standard for the diagnosis of PTE, but due to the high cost of testing and high equipment prices, its popularity in grassroots hospitals is not high. Therefore, analyzing the risk factors of AECOPD patients complicated with PTE is of great significance for early identification of PTE. At present, although there are reports on the risk factors for concurrent PTE in AECOPD patients, there is no specific predictive model for predicting PTE in AECOPD patients. In clinical practice, risk assessment tools such as the Caprini risk assessment model and the modified Geneva scale are commonly used for VTE, while the Wells score is the PTE diagnostic likelihood score. The evaluation indicators of these tools are mostly clinical symptoms, and laboratory indicators are less involved, It is difficult to comprehensively reflect the patient's condition, so the specificity of AECOPD patients with PTE is not strong. The column chart model established in this study presents a visual prediction model, which is convenient for clinical use and has positive help for the early detection of AECOPD patients with PTE. In addition, medical staff can present the calculation results of the column chart model to patients, making it easier for patients to understand. It helps improve the early identification and treatment of AECOPD combined with PTE patients, thereby improving prognosis.
The goal of this clinical trial is to compare in describe participant population health conditions. The main questions it aims to answer are: - To obtain the limb movement and bed mobility limits after femoral venipuncture, in order to provide a basis and support for clinical reduction of postoperative braking time and alleviation of postoperative patient subjective discomfort - To analyze the effect of perioperative factors such as anticoagulation and sheath size on the complication rate, so as to develop a detailed and systematic strategy to stop bleeding after femoral venipuncture - The advantages and necessity of reducing the postoperative braking time in bed were demonstrated by objective evaluation of patients' postoperative subjective feelings and mental status. In this prospective study, 150 patients who underwent femoral vein puncture intervention were selected by inclusion and exclusion criteria, and were randomly divided into control group, trial A group and trial B group by SPSS software, with 50 cases each. In the control group, the lower limb of the punctured side was braked for 4 hours + 8 hours after routine postoperative activities; in the trial A group, the lower limb of the punctured side was braked for 2 hours + 4 hours after postoperative activities; in the trial B group, the lower limb of the punctured side was braked for no postoperative activities + 2 hours after postoperative activities, and the corresponding evaluation indexes and questionnaires were used to record the hemostasis at the puncture site, whether complications occurred and the subjective feelings of patients in each group after completing the corresponding strategies. The data were also recorded along with the general information of the patients and the factors that may cause bleeding in the perioperative period. Statistical analysis was used to classify, summarize and draw conclusions about the data obtained, analyze the limit of braking bed time, and formulate scientific hemostatic strategies.
This prospective, observational, post-market study will be performed to collect patient-level data on the Celect Platinum Vena Cava Filter Sets and the Günther Tulip Vena Cava Filter Retrieval Set to confirm continued safety and performance of the devices throughout their expected lifetime and continued acceptability of the benefit:risk ratio. Additionally, the study intends to evaluate longer-term (i.e., up to 5 years) outcome data while the filter is indwelling.
The project will investigate the feasibility of a physiotherapy intervention for patients diagnosed with deep vein thrombosis for whom a physiotherapy intervention is not currently part of clinical practice in Denmark. Specifically, the project will investigate if an early-initiated physiotherapy intervention for patients who are admitted acutely with first-time deep vein thrombosis (DVT), can be carried out and is experienced as valuable for the patients.
The aim of the study is to evaluate the safety and performance of the ClotTriever catheter in the treatment of patients with symptomatic iliofemoral deep vein thrombosis (DVT)
This is a multicentric, prospective, observational study with two cohorts and adjunctive procedure. It aims at collecting and analyzing data about the function of an innovative hospital-territory integration health service for the management of patients with intermediate urgency, or emergency department "white codes." This service, activated in the participating centers, will be provided in two alternative modalities, one so-called "dual specialty" (cardiology and diabetes specialist outpatient clinic) and a second one more focused on the figure of the specialist in Internal Medicine. The investigators will monitor the population treated in these centers (presenting complaint, medical history, clinical-radiological data, performed therapies and overall health path) and the degree of satisfaction of the General Practitioners who sent their patients there and the degree of satisfaction of the patients themselves. The data collected will also be used to evaluate the effectiveness of the outpatient clinics in terms of reducing improper admissions to the Emergency Departments and hospitalizations. The two modes of service delivery will be compared. This is an 18-month study, sponsored by our Scientific Directorate and carried out on a nonprofit basis. The study will enroll 246 patients and 30 healthy volunteer General Practitioners. The clinical trial will be conducted in accordance with Good Clinical Practice standards.
A new Clinical Score (CS) to rule out Deep Vein Thrombosis (DVT) has to be derived and internally validated (with bootstrap method), from patients suspected of DVT in Italy. Primary care physicians (general practitioners) in Lombardy will be instructed to inform patients suspected of DVT about this research and get in touch with the team to get details and, eventually, volunteer for the study. The CS includes categorical variables and a continuous variable: the differential leg skin temperature measured with a low-cost handheld infrared thermometer in object surface mode.
This primary care study aims to compare the "time in therapeutic range" (TTR) of two strategies for monitoring the international normalized ratio (INR) over 6 months in nursing homes. The population consists of frail elderly patients for whom Anti-Vitamin K treatments are frequent, and who are consequently more prone to embolic and hemorrhagic complications.
