Impact of the COVID-19 Pandemic on Infective Endocarditis Management and Outcomes: Analysis of a National Clinical Database.

COVID-19 has widely affected health care delivery, but its impact on the management of infective endocarditis (IE), including valve surgery, is uncertain. We compared the national trends in admissions, demographics, and outcomes of IE before and after COVID-19 onset, using a national sample of IE admissions between 2016 and 2022 from the Vizient Clinical Database. The pre-COVID-19 and post-COVID-19 time periods were separated by the start of the second quarter of 2020, the time during which the COVID-19 pandemic was declared.

Inadequate Adherence to Imaging Surveillance and Medical Management in Patients with Duplex Ultrasound-Detected Carotid Artery Stenosis.

Background: It is recommended that patients with ≥50% carotid artery stenosis undergo surveillance imaging and atherosclerotic risk reduction medical therapies, regardless of whether revascularization is performed. The objective of this study was to determine rates of adherence to these recommended measures and to identify risk factors for nonadherence.

Methods: A retrospective analysis was performed of all carotid duplex ultrasound (DUS) from 2016 to 2017 at a single institution.

Dysregulation of NRAP degradation by KLHL41 contributes to pathophysiology in nemaline myopathy.

Nemaline myopathy (NM) is the most common form of congenital myopathy that results in hypotonia and muscle weakness. This disease is clinically and genetically heterogeneous, but three recently discovered genes in NM encode for members of the Kelch family of proteins. Kelch proteins act as substrate-specific adaptors for Cullin 3 (CUL3) E3 ubiquitin ligase to regulate protein turnover through the ubiquitin-proteasome machinery.
