The Effect of the COVID Pandemic on the Rate of Same-Day Discharge in Primary Hip and Knee Arthroplasty.

Background: Same-day discharge (SDD) following primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) started increasing prior to 2020. The purpose of this study was to evaluate the change in the rate of SDD after the pandemic and determine whether those changes became permanent.

Methods: The annual rate of SDD for 15,208 primary THA and TKA cases performed between January 1, 2015, and September 9, 2022, at a single institution was determined.

In December 2021 the U.S. Government announced a new, whole-of-government $1.

Predicting time to serologic diagnosis of AQP4+ NMOSD based on clinical factors and social determinants of health.

Background: Early serologic diagnosis and initiation of targeted therapy are associated with better outcomes in aquaporin-4 IgG positive (AQP4+) neuromyelitis optica spectrum disorder (NMOSD).

Objective: To determine predictors of time to serologic diagnosis of AQP4+ NMOSD.

Methods: In CANOPTICS, a multi-centre, Canadian cohort study of NMOSD, we retrospectively evaluated time from the first clinical attack to first positive AQP4-IgG serology.

Does Powered Femoral Broaching Compromise Patient Safety in Total Hip Arthroplasty?

Background: During manual broaching (MB) in total hip arthroplasty (THA), off-axis forces delivered to the proximal femur and broach malalignment can lead to fractures and cortical perforations. Powered broaching (PB) is a novel alternative that delivers consistent impaction forces and reduces workload. This is the first large-scale study to compare intraoperative and 90-day rates of periprosthetic femur fractures (PFFs) and perforations in THA performed using MB vs PB.

Effect of encoding variability on rejection of non-corresponding lures: Role of retrieval processes.

The primary goal of the current study was to assess whether different retrieval processes moderated the effect of encoding variability on accurate performance on the A-B' test format of the forced-choice Mnemonic Similarity Task (MST). Young adults completed the A-B' test format of the forced-choice MST and determined whether their recognition memory judgment was based on recall-to-reject processing, recall-to-accept processing, familiarity, or guessing. When guesses were excluded from correct trials, fixation counts were higher to the A stimulus than the B stimulus at encoding.
