Bighorn sheep (BHS) populations have been reported to experience high levels of morbidity and mortality following infection with . This contrasts with the subclinical presentation in domestic sheep (DS). Understanding this difference requires baseline knowledge of pre- and post-infection immune responses of both species.

However, the diagnostic performance and efficiency of swabbing the nasal passage compared to other anatomical locations has not been determined within sheep populations. The goal of this research was to assess the diagnostic capability of nasopharyngeal swabs in comparison to nasal swabs for the detection of Mycoplasma ovipneumoniae.

Objectives: The authors sought to evaluate institutional variability in radiation doses during transcatheter valve interventions.
Methods: Using a large statewide registry, transcatheter edge-to-edge mitral valve repair, transcatheter mitral valve replacement, and transcatheter aortic valve replacement procedures between January 1, 2020, and December 31, 2022, with an air kerma (AK) recorded were analyzed.
Article Synopsis
- Prior research on aortic valve replacement (AVR) in patients with normal-flow, low-gradient aortic stenosis (NF-LG AS) has shown mixed results concerning survival benefits, and the impact on quality of life (QoL) after transcatheter AVR (TAVR) in this group has been underexplored.
- This study aimed to assess the changes in QoL after TAVR between patients with NF-LG AS and those with high-gradient aortic stenosis (HG-AS).
- Results indicated that while the one-year mortality rate was higher for NF-LG AS patients compared to HG-AS patients, the improvement in QoL after TAVR was similar for both groups, suggesting a need for further research on
Background: Cardiac rehabilitation (CR) is strongly recommended for a spectrum of cardiovascular conditions and procedures including aortic valve replacement.
Objectives: The purpose of this study was to characterize patient and hospital factors associated with CR participation after transcatheter aortic valve replacement (TAVR) and determine which factors explain hospital-level variation in CR participation.
Methods: We linked clinical and administrative claims data from patients who underwent TAVR at 24 Michigan hospitals between January 1, 2016 and June 30, 2020 and obtained rates of CR enrollment within 90 days of discharge.
