Patient Perception of Allograft Versus Autograft in ACL Reconstruction Using a Validated Online Survey Marketplace.

Background: Little is known regarding the opinions of the general population on anterior cruciate ligament (ACL) graft options.

Purpose: To evaluate the general population's perception of the use of allografts versus autografts in ACL reconstruction using a previously validated online marketplace platform.

Methods: A prospective 34-question survey was distributed via the online marketplace.

Principled Conscientious Provision: Referral Symmetry and Its Implications for Protecting Secular Conscience.

"Conscientious provision" refers to situations in which clinicians wish to provide legal and professionally accepted treatments prohibited within their (usually Catholic) health care institutions. It mirrors "conscientious objection," which refers to situations in which clinicians refuse to provide legal and professionally accepted treatments offered within their (usually secular) health care institutions. Conscientious provision is not protected by law, but conscientious objection is.

Outcomes of Primary Anterior Cruciate Ligament (ACL) Repair for Proximal Tears: A Systematic Review and Meta-Analysis.

The purpose of this study is to compare failure rates among different techniques of primary anterior cruciate ligament (ACL) repair for the treatment of proximal ACL ruptures. Meta-analysis and systematic review were completed, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Studies from Embase, Cochrane, and PubMed published between June 2011 and June 2022 reporting outcomes of primary ACL repair on proximal tears with a minimum two-year follow-up were included.

Improvement of oxygen reduction activity and stability on a perovskite oxide surface by electrochemical potential.

The instability of the surface chemistry in transition metal oxide perovskites is the main factor hindering the long-term durability of oxygen electrodes in solid oxide electrochemical cells. The instability of surface chemistry is mainly due to the segregation of A-site dopants from the lattice to the surface. Here we report that cathodic potential can remarkably improve the stability in oxygen reduction reaction and electrochemical activity, by decomposing the near-surface region of the perovskite phase in a porous electrode made of LaSrCoFeO mixed with SmCeO.

Spatial sampling bias and model complexity in stream-based species distribution models: A case study of Paddlefish () in the Arkansas River basin, USA.

Leveraging existing presence records and geospatial datasets, species distribution modeling has been widely applied to informing species conservation and restoration efforts. Maxent is one of the most popular modeling algorithms, yet recent research has demonstrated Maxent models are vulnerable to prediction errors related to spatial sampling bias and model complexity. Despite elevated rates of biodiversity imperilment in stream ecosystems, the application of Maxent models to stream networks has lagged, as has the availability of tools to address potential sources of error and calculate model evaluation metrics when modeling in nonraster environments (such as stream networks).
