Diagnostic Cytopathology, EarlyView.ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.

Deep Underground Science and Engineering, EarlyView.Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

ESC Heart Failure, Volume 12, Issue 2, Page 879-887, April 2025.Abstract Background Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF). Aims This study aimed to characterize patients with exertional dyspnoea and normal/near‐to‐normal N‐terminal pro‐brain natriuretic peptide (NT ...
