Anomalies in Hadronic B Decays.

In this Letter, we perform fits to B→PP decays, where B={B^{0},B^{+},B_{s}^{0}} and the pseudoscalar P={π,K}, under the assumption of flavor SU(3) symmetry [SU(3)_{F}]. Although the fits to ΔS=0 or ΔS=1 decays individually are good, the combined fit is very poor: there is a 3.6σ disagreement with the SU(3)_{F} limit of the standard model (SM_{SU(3)_{F}}).

Adjunctive Dorsal Spanning Plate Fixation in the Stabilization of Perilunate Dislocations.

Purpose: To compare the biomechanical properties of adjunctive dorsal spanning plate (DSP) fixation with traditional K-wire fixation of perilunate dislocations in a cadaveric model.

Methods: Fourteen fresh-frozen cadaveric wrists underwent simulated perilunate injury. The specimens were randomly allocated to either K-wire fixation versus K-wire and DSP fixation.

Digital Preoperative Huddle Platform Use Leads to Decreased Surgical Cost.

Background And Objectives: Communication has a well-established effect on improving outcomes. The current study evaluated the effect of multidisciplinary preoperative team communication using a digital huddle software platform on operating room costs.

Methods: A digital huddle software platform was implemented in March 2022 for neurosurgical procedures performed at a single tertiary care center.

A methodology for estimating SARS-CoV-2 importation risk by air travel into Canada between July and November 2021.

Background: Estimating rates of disease importation by travellers is a key activity to assess both the risk to a country from an infectious disease emerging elsewhere in the world and the effectiveness of border measures. We describe a model used to estimate the number of travellers infected with SARS-CoV-2 into Canadian airports in 2021, and assess the impact of pre-departure testing requirements on importation risk.

Methods: A mathematical model estimated the number of essential and non-essential air travellers infected with SARS-CoV-2, with the latter requiring a negative pre-departure test result.

Experimenting With the New Frontier: Artificial Intelligence-Powered Chat Bots in Hand Surgery.

Increased utilization of artificial intelligence (AI)-driven search and large language models by the lay and medical community requires us to evaluate the accuracy of AI responses to common hand surgery questions. We hypothesized that the answers to most hand surgery questions posed to an AI large language model would be correct. Using the topics covered in Green's 8 Edition as a guide, 56 hand surgery questions were compiled and posed to ChatGPT (OpenAI, San Francisco, CA).
