Doxorubicin (DOXO) has long been used clinically and remains a key drug in cancer therapy. DOXO-induced cardiomyopathy (DICM) is a chronic and fatal complication that severely limits the use of DOXO. However, there are very few therapeutic agents for DICM, and there is an urgent need to identify those that can be used for a larger number of patients.

Local hemodynamics play an essential role in the initiation and progression of coronary artery disease. While vascular geometry alters local hemodynamics, the relationship between vascular structure and hemodynamics is poorly understood. Previous computational fluid dynamics (CFD) studies have explored how anatomy influences plaque-promoting hemodynamics.

To develop a predictive model for improvement of ejection fraction 1 year after heart failure with reduced ejection fraction (HFrEF) following acute ST-segment elevation myocardial infarction (STEMI). This nested case-control study included STEMI patients diagnosed with HFrEF from a prospective multicenter multimodality imaging cohort between August 2014 and March 2021. Based on the improvement of left ventricular ejection fraction (LVEF) at baseline and 1-year follow-up, the patients were classified into the heart failure with improved ejection fraction (HFimpEF) group and the persistent HFrEF group.

Regional Image Quality Scoring for 2-D Echocardiography Using Deep Learning.

Ultrasound Med Biol

January 2025

Department of Circulation and Medical Imaging, Norwegian University of Science and Technology - NTNU, Trondheim, Norway; Health Research, SINTEF, Trondheim, Norway.

Objective: To develop and compare methods to automatically estimate regional ultrasound image quality for echocardiography separate from view correctness.

Methods: Three methods for estimating image quality were developed: (i) classic pixel-based metric: the generalized contrast-to-noise ratio (gCNR), computed on myocardial segments (region of interest) and left ventricle lumen (background), extracted by a U-Net segmentation model; (ii) local image coherence: the average local coherence as predicted by a U-Net model that predicts image coherence from B-mode ultrasound images at the pixel level; (iii) deep convolutional network: an end-to-end deep-learning model that predicts the quality of each region in the image directly. These methods were evaluated against manual regional quality annotations provided by three experienced cardiologists.

Objective: This study aimed to investigate the effects of nasal obstruction on the coordinated movement of perioral tissues during mastication using a motion capture system.

Design: Twelve healthy adult participants were instructed to chew gum only on their habitual masticatory side for 30 s, with and without nasal obstruction. Nasal obstruction was induced by blocking nasal breathing with a nose clip.
