Noncanonical Short-Latency Auditory Pathway Directly Activates Deep Cortical Layers.

Auditory processing in the cerebral cortex is considered to begin with thalamocortical inputs to layer 4 (L4) of the primary auditory cortex (A1). In this canonical model, A1 L4 inputs initiate a hierarchical cascade, with higher-order cortices receiving pre-processed information for the slower integration of complex sounds. Here, we identify alternative ascending pathways in mice that bypass A1 and directly reach multiple layers of the secondary auditory cortex (A2), indicating parallel activation of these areas alongside sequential information processing.

Epicardial adipose tissue, cardiac damage, and mortality in patients undergoing TAVR for aortic stenosis.

Computed tomography (CT)-derived Epicardial Adipose Tissue (EAT) is linked to cardiovascular disease outcomes. However, its role in patients undergoing Transcatheter Aortic Valve Replacement (TAVR) and the interplay with aortic stenosis (AS) cardiac damage (CD) remains unexplored. We aim to investigate the relationship between EAT characteristics, AS CD, and all-cause mortality.

Burden of Valvular Heart Diseases in a Racially and Ethnically Diverse Population: The Bronx-Valve Registry.

Background: Valvular heart disease (VHD) is a major focus of cardiovascular medicine, but limited data are available for racial and ethnic minorities. The aim was to assess the burden and clinical correlates of VHD in a highly diverse area of the United States.

Methods And Results: Individuals with echocardiographic diagnosis of native VHD between January 2010 and December 2019 at a quaternary care health system of the Bronx (New York, USA) were included.

Compartmental location of middle ear inflammatory polyps in cats: 9 cases (2021-2023).

Objectives: To report the compartmental location of feline aural inflammatory polyps within the tympanic bulla.

Materials And Methods: Nine client-owned cats with clinical signs and middle ear filling consistent with feline aural inflammatory polyps were prospectively pre-selected and underwent unilateral or bilateral ventral bulla osteotomy. Preoperative and surgical findings, complications and outcomes were recorded.
