Filter by:The clinical trial aimes to evaluate multiple large language models in respiratory disease consultations by comparing their performance to that of human doctors across three major medical consultation scenarios. The main question aims to answer are: - How do large language models perform in comparison to human doctors in diagnosing and consulting on respiratory diseases across various clinical scenarios? In three clinical scenarios including the online query section, the disease diagnosis section and the medical explanation section, research assistants or volunteers will be asked to cross-question all LLMs or real doctors using predefined online questions and their own issues. After each questioning session, a short washout period is implemented to eliminate potential biases.
Pulmonary embolism (PE) presents notable risks of morbidity and mortality, underscoring the need for customized anticoagulant treatment. There is a scarcity of research examining drug-related issues (DRPs) in PE. This research endeavor seeks to assess how addressing DRPs affects the clinical outcomes of PE patients receiving outpatient care, offering valuable insights to bolster patient safety measures. This study will conduct a randomized controlled trial on PE patients in Istanbul, Turkey, from January 15, 2022, to January 15, 2023. The intervention group (IG) will receive clinical pharmacist (CP) recommendations for DRPs, while the control group (CG) will undergo observation only. Evaluations will occur at 90- and 180-days post-discharge, focusing on DRPs, CP interventions, and patient outcomes. Data will be systematically recorded and analyzed, adhering to ethical standards and employing the PCNE v9.1 classification system.
The purpose of this study is to identify and validate new imaging biomarkers allowing an individual phenotyping of patient with venous thrombo-embolism (VTE), mainly in terms of recurrence risk assessment and to distinguish provoked from unprovoked VTE. To do so, the investigators will create a retrospective imaging database including multiple imaging modalities, performed at diagnosis of the VTE.
Evaluation of circulating endothelial inflammatory biomarkers in response to GLP-1 agonist Semaglutide in acute pulmonary embolism
Estimation of the incidence of pulmonary embolism in patients presenting to the Emergency Department with hemoptysis.
The investigators' aim in this study is to assess the sensitivity and accuracy of YEARS algorithm in the diagnosis of PE.
This multicenter international prospective cohort study will include patients with AIS with a known or newly diagnosed anticoagulant-naïve AF. All centers will use the same transcranial Doppler machine for one-hour monitoring with bilateral 2-MHz probes within 24 hours of symptom onset. Recordings will be analyzed for MES by a blinded central reader. The primary aim is to determine the proportion of patients with MES and the association of MES with functional outcomes assessed by a modified Rankin scale (mRS) score at 90 days.
A blood sample was taken before starting the patients on any thrombolytic treatment. The positivity threshold for D-Dimer was above 250 ng/ml. CTPA was performed after performing blood sampling. Patients with confirmed pulmonary embolisms were admitted to ICU for continued monitoring of vitals, consciousness level, and signs of tissue perfusion. Signs of shock or hemodynamic instability should be observed regularly. Patients were managed in the ICU with anticoagulants by parenteral use. The most commonly used items were Heparin, either Unfractionated (UFH) or low-molecular-weight heparin (LMWH).D-dimer levels can leverage to detect PE. D-dimer levels can help in guiding the option of CTPA and the initiation of treatment for patients with suspected PE.
The goal of this single center prospective controlled observational and interventional trial is to investigate and compare origin of air emboli when different venous cannulation methods is used in patients undergoing cardiac surgery with extracorporeal circulation. 40 consecutive elective patients will be included in two groups, depending on the procedure requiring bicaval or cavoatrial cannulation. After assorted into respective group, patients will be block randomized (five groups consisting of eight patients each) to either intervention group (low venous reservoir volume, 200-300 mL) or control group (venous reservoir volume > 300 mL). Primary endpoint is to investigate if the amount of air emboli passing through the oxygenator to the arterial line differs between bicaval and cavoatrial venous cannulation during extracorporeal circulation. Secondary endpoints are the relative difference in amount air emboli between the groups, if there is any correlation between the amount of air in venous line and the amount of air passing through the oxygenator to the arterial line during extracorporeal circulation, and if difference is seen on the amount of air passing through the oxygenator depending on the level of volume in the venous reservoir.
