Purpose: The objective was to use cyclic tensile loading to compare the gap formation at suture site of three different suture materials to repair bovine radial meniscal tears: (1) polyglactin sutures, (2) tough adhesive puncture sealing (TAPS) sutures and (3) ultra-high molecular weight polyethylene (UHMWPE) sutures.
Methods: Twelve ex vivo bovine knees were dissected to retrieve the menisci. Complete radial tears were performed on 24 menisci, which were then separated into three groups and repaired using either pristine 2-0 polyglactin sutures, TAPS sutures (2-0 polyglactin sutures coated with adhesive chitosan/alginate hydrogels) or 2-0 UHMWPE sutures with a single stitch.

Background: Non-obstructive azoospermia (NOA), the severe type of male infertility. The objective of this study was to evaluate the predictive accuracy of a prediction model of sperm retrieval failure with fine needle aspiration (FNA).
Methods: This study involved 769 NOA patients (dataset 1) undertaking FNA and 140 NOA patients undertaking mTESE (dataset 2).

Purpose: Report 2-year outcomes from a prospective, multicenter, non-randomized, single-arm study designed to further assess the safety and effectiveness of the Celect and the Günther Tulip Vena Cava Filters.
Materials And Methods: The BLIND study enrolled patients requiring temporary or permanent IVC filter placement for the prevention of pulmonary embolism (PE). The primary effectiveness endpoint was the rate of technical placement success and 12-month freedom from new symptomatic PE while a filter was indwelling.

The prevalence of sperm DNA fragmentation (SDF) is significantly higher in males with infertility, which is often associated with oligozoospermia and hypospermia. It can also occur in patients with infertility who have normal conventional semen indicators. The etiologies involve aberrations in sperm maturation, dysregulated apoptotic processes, and heightened levels of oxidative stress.

Background: Retrieval practice is a highly effective learning strategy that enhances long-term retention by encouraging the active recall of information. However, the optimal question format for maximizing knowledge retention remains uncertain. In this study, we compared the effect of very short answer (VSAQ) versus multiple-choice question (MCQ) practice tests on students' knowledge retention.
