Impact of papillary muscle infarction on atrial and ventricular myocardial deformation in non-anterior STEMI patients.
Int J Cardiovasc Imaging

Department of Radiology, Azienda Ospedaliero Universitaria (A.O.U.), di Cagliari - Polo di Monserrato s.s. 554 Monserrato (Cagliari), Monserrato, 09045, Italy.
The purpose of this study was to explore the impact of papillary muscle (PPM) infarction on left atrial and ventricular strain parameters in patients with non-anterior ST-segment elevation myocardial infarction (NA-STEMI) using cardiovascular magnetic resonance (CMR). This retrospective study performed CMR scans on 88 consecutive patients with NA-STEMI (68 males, 65 ± 10.05 years).

Transcatheter edge-to-edge repair (TEER) is approved for patients with symptomatic severe mitral regurgitation (MR) who are deemed inoperable or at high surgical risk with life expectancy of more than 1 year, but has also been used off-label in patients with hypertrophic obstructive cardiomyopathy (HOCM) for symptomatic relief who are not candidates for septal reduction therapy. An 83-year-old woman with decompensated heart failure was found to have HOCM with systolic anterior motion of the mitral valve and a large P2 flail segment with ruptured cords. TEER was performed resulting in mild MR and resolution of the prior left ventricular outflow tract gradient.

Purpose: To report a case of corneoscleral juvenile xanthogranuloma (JXG) with progressive anterior segment involvement refractory to topical steroids.
Observations: A 4-month-old male was referred for a new-onset subconjunctival lesion in the right eye. He was found to have a thickened, yellow corneoscleral lesion and hyphema, presumed to be ocular JXG.
Neonatal inflammation and near-term white matter microstructure in infants born very preterm.
Neuroimage Rep
December 2024
Department of Pediatrics, Division of Developmental-Behavioral Pediatrics, Stanford University, Stanford, CA, USA.
Background: Severe neonatal inflammatory conditions in very preterm infants (VPT: <32 weeks gestational age, GA) are linked to adverse neurodevelopmental outcomes. Differences in white matter (WM) microstructure of the corpus callosum (CC) have been observed at age 6 in VPT children with a history of severe neonatal inflammation. The goal of this study was to determine whether these CC differences can be detected at term-equivalent age using diffusion MRI (dMRI), and whether neonatal inflammation is associated with altered WM in additional tracts implicated in the encephalopathy of prematurity.

Cataract is the leading ocular disease of blindness and visual impairment globally. Deep neural networks (DNNs) have achieved promising cataracts recognition performance based on anterior segment optical coherence tomography (AS-OCT) images; however, they have poor explanations, limiting their clinical applications. In contrast, visual features extracted from original AS-OCT images and their transform forms (e.
