7-Year outcomes after surgical aortic valve replacement with a stented bovine pericardial bioprosthesis in over 1100 patients: a prospective multicenter analysis.

Objectives: Safety, efficacy, and durability are important considerations when selecting a bioprosthesis for aortic valve replacement (AVR). This study assessed 7-year clinical outcomes and haemodynamic performance of the Avalus bioprosthesis.

Methods: Patients indicated for surgical AVR were enrolled in this prospective, nonrandomized trial, conducted across 39 sites globally.

Comparing contribution of bony and cartilaginous endplate changes to intervertebral disc degeneration.

Objective: To compare the degenerative features of cartilaginous endplate with bony endplate in association with intervertebral degeneration in local population at radiographic, macroscopic and microscopic level in human motion segments.

Methods: This cross-sectional descriptive study examined 59 lumbar spine motion segments from adult male cadavers at the Department of Anatomy, University of Health Sciences, Lahore, between May and September, 2022. Radiographic assessment observed bony endplate (BEP) for the presence of sclerosis & osteophytes and degeneration scores from 1-8 were assigned.

Application of a New Device for Vision Relaxation in Computer Users.

This study aims to explore the potential of a novel EYE ROLL device designed to facilitate guided vision relaxation exercises in an open space. A prospective study was performed on 89 participants who perform screenwork for at least four hours daily. All participants were randomly divided into three groups: a Control group with no exercising, a Manual group undertook manual vision relax ation exercises, and an Eyeroll group engaged in EYE ROLL device-assisted vision relaxation exercises.

From Triumph to Trial: A Case Study of Non-Tuberculous Mycobacterium After Tetralogy of Fallot (TOF) Correction in an Immunocompetent Child.

, a slow-growing non-tuberculous mycobacterium (NTM), presents diagnostic challenges due to its resemblance to and other NTMs. While NTM infections and tuberculosis share clinical and radiological features, their management strategies differ. Accurate differentiation is pivotal, as misdiagnosing NTM infections such as MDR-TB can lead to ineffective treatments.
