Purpose: Cardiac computed tomography angiography (CCTA) has significantly advanced the visualization of cardiac structures, particularly valves. We assessed the diagnostic performance of CCTA in diagnosing the most common disorders affecting the aortic valves requiring surgery-papillary fibroelastoma, infective endocarditis, and degeneration.
Methods: This retrospective study included patients who underwent aortic valve resection between 2016 and 2023 and had a preceding CCTA.
Article Synopsis
- The study investigates risk factors for proliferative vitreoretinopathy (PVR), a common complication after retinal detachment surgery.
- A large patient database was analyzed, identifying systemic (like age, gender, and smoking) and ocular (such as trauma and previous eye conditions) factors that correlate with increased PVR risk.
- The findings emphasize the importance of considering these risk factors in surgical planning and treatment to prevent PVR in patients with retinal detachment.
Article Synopsis
- Limited annotated datasets for 3D biomedical imaging make it challenging to train machine learning models for accurate disease prediction.
- The SLIViT model, pre-trained on 2D scans, effectively predicts disease-risk factors by processing 3D scans into 2D images and integrating their features.
- SLIViT outperformed existing models in various learning tasks and matched the accuracy of trained specialists, potentially saving time and costs in clinical settings.
Laboratory scale conventional single-use bioreactor was used to investigate the effect of different stirrer speeds on the Arthrospira platensis (Spirulina platensis) culture. Experiments were handled in two steps. First step was the selection of the stirring speeds, which was simulated via using CFD, and the second was the long term cultivation with the selected speed.

Subjects/methods: Patients with DR who underwent both Optos ultrawidefield (UWF) pseudocolor imaging and macular OCTA (Cirrus Angioplex, 6 × 6 mm) were included in this cross-sectional observational study. The distribution of DR lesions was assessed by comparing each of the peripheral ETDRS extended fields (3-7) against their corresponding ETDRS field, hence eyes were defined as either having predominantly peripheral lesions (PPL) or predominantly central lesions (PCL).
