Three-dimensional (3D) echocardiography-derived right ventricular (RV) ejection fraction (EF) and global longitudinal strain (GLS) are valuable RV functional markers; nevertheless, they substantially load-dependent. Global myocardial work index (GMWI) is a novel parameter calculated by the area of pressure-strain loop. By adjusting deformation to instantaneous pressure, it may reflect contractility.To test this hypothesis, we enrolled 60 patients who underwent pressure-conductance...
Background/Objectives: Donor-derived cell-free DNA (dd-cfDNA) is a marker of graft injury that increases in acute rejection and has excellent negative predictive value. Left ventricular global longitudinal strain (LVGLS) strain-derived myocardial work indices are novel echocardiographic parameters with growing applications. Still, they have been poorly investigated heart transplant (HTx) recipients so far. We sought to examine the diagnostic impact left diagnosing as assessed by dd-cfDNA...
Despite the significant contribution of circumferential shortening to global ventricular function, data are scarce concerning its prognostic value on long-term mortality. Accordingly, our study aimed assess both left (LV) and right (RV) longitudinal (GLS) strain (GCS) using three-dimensional echocardiography (3DE) determine their importance.Three hundred fifty-seven patients with a wide variety left-sided cardiac diseases were retrospectively identified (64 ± 15 years, 70% males) who...
Conventional echocardiographic parameters of right ventricular (RV) function are afterload-dependent. Therefore, incorporating RV pressures may enable the formulation new that reflect intrinsic accurately. Accordingly, we sought to develop an artificial intelligence-based method reconstruct pressure curve based on peak pressure. We invasively acquired in 29 heart failure patients before and after implanting a left (LV) assist device. Using these tracings, trained various machine learning...
Objectives: Melanoma is the deadliest form of skin cancer, but it can be fully cured through early detection and treatment in 99% cases. Our aim was to develop a non-invasive machine learning system that predict thickness melanoma lesion, which proxy for tumor progression, dermoscopic images. This method serve as valuable tool identifying urgent cases treatment.Methods: A modern convolutional neural network architecture (EfficientNet) used construct model capable classifying images lesions...
Current guidelines recommend considering multiple factors while deciding between cardiac resynchronization therapy with a defibrillator (CRT-D) or pacemaker (CRT-P). Nevertheless, it is still challenging to pinpoint those candidates who will benefit from choosing CRT-D device in terms of survival.
Abstract Choosing the optimal device during cardiac resynchronization therapy (CRT) upgrade can be challenging. Therefore, we sought to provide a solution for identifying patients in whom upgrading CRT-defibrillator (CRT-D) is associated with better long-term survival than CRT-pacemaker (CRT-P). To this end, first applied topological data analysis create patient similarity network using 16 clinical features of 326 without prior ventricular arrhythmias who underwent CRT upgrade. Then,...
Abstract Background and aim Over the past decades, we have witnessed an immense expansion in arsenal performance of machine learning (ML) algorithms. One most important fields that could benefit from these advancements is biomedical science. To streamline training evaluation binary classifiers, constructed a universal flexible ML framework uses tabular data as input. Methods results Our requires input to be provided comma-separated values file, which rows correspond subjects columns...
Abstract Conventional echocardiographic parameters of right ventricular (RV) function are heavily afterload-dependent. Therefore, the incorporation RV pressure curve may enable formulation new that reflect intrinsic more accurately. Accordingly, we sought to develop an artificial intelligence-based method can reconstruct based on peak pressure. We invasively acquired in 29 heart failure patients before and after implantation a left (LV) assist device. Using these tracings, trained various...
Background Three-dimensional (3D) echocardiography-derived right ventricular (RV) ejection fraction (EF) and global longitudinal strain (GLS) are valuable RV functional markers; nevertheless, they substantially load-dependent. Global myocardial work index (GMWI) adjusts deformation to instantaneous pressure; therefore, it may better reflect contractility. Accordingly, we aimed calculate GMWI using 3D echocardiography examine its relationship with contractility’s gold standard invasive...
<b>Ziel der Untersuchung</b> Koloskopien werden ausschließlich mithilfe Insufflationstechnik durchgeführt. Nur so ist es möglich, ein ausreichendes Sichtverhältnis zur Untersuchung Darmmukosa zu schaffen. Nach Insufflation klagen Patienten häufig über Völlegefühl, dessen Ursache auf das Dickdarmspannungsgefühl zurückzuführen ist. Dieses Schmerzgefühl hat einen negativen Einfluss den Patienten, sich in Abnahme Kooperationsbereitschaft bei Untersuchungen bemerkbar macht und damit die...
For more complex classification problems it is inevitable that we use increasingly and cumbersome classifying models. However, often do not have the space or processing power to deploy these models.Knowledge distillation an effective way improve accuracy of otherwise smaller, simpler model using a teacher network ensemble networks. This can classifier with comparable while small enough deploy.In this paper evaluate certain features distilling method, trying its results. These experiments...
