SARS-CoV-2 Placentitis: A Review of Pathologic Findings and Discussion of Differential Diagnosis.

Context.—: Maternal SARS-CoV-2 infection has been associated with increased adverse events in the mother, as well as increased stillbirths (11.5 per 1000), spontaneous abortions, and premature delivery.

Antimicrobial activity of immobilized mycocins in sodium alginate on fecal coliforms.

is a yeast-producing mycocins and has antimicrobial action. is the predominant bacterium of the coliforms group; its presence in water indicates fecal contamination, being used as an indicator of microbiological analyses. The immobilization of cells and substances demonstrates great potential for biotechnological applications.

Four-Wave Mixing at peV Energy Scales.

We measure the nonlinear magnetic susceptibility χ^{(3)} of the disordered quantum Ising magnet LiHo_{0.045}Y_{0.955}F_{4} and demonstrate four-wave mixing due to coherent (anti-)Stokes Raman scattering at ∼100  Hz (peV) energy scales.

Spine Surgery Outcomes in Patients With Limited English Proficiency.

Study Design: Retrospective cohort study.

Objective: The purpose of this study is to investigate the impact of language-discordant spine care. Specifically, do non-English speakers (NES) experience (1) increased length of stay? (2) increased rates of complications (ie, intra/perioperative complications, revision surgery, reoperation)?

Background: To provide the best care, there exists a growing focus on understanding which patient groups may be at greater risk for poorer outcomes.

Mentor-Guided Learning in Immersive Virtual Environments: the Impact of Visual and Haptic Feedback on Skill Acquisition.

In the early stages of learning a technical skill, trainees require guidance from a mentor through augmented feedback to develop higher expertise. However, the impact of such feedback and the different modalities used to communicate it remain underexplored in immersive virtual environments (IVE). This paper presents a study in which 27 participants were divided into three groups to learn a tool manipulation trajectory in an IVE.
