The Use of 3D Printing in Fetal Surgery for Surgical Planning: A Scoping Review.

: We sought to identify in which clinical scenarios 3D printed models are used to plan for fetal surgeries as well as the main purpose and the imaging method utilized for the models. In addition, we describe benefits and shortcomings of the models, as well as potential future improvements. : In this scoping review, data were collected retrospectively from scientific databases (PubMed, Embase, Cochrane CENTRAL, CINAHL, Scopus, and the Web of Science platform) and screened by title, abstract, and full text against strict criteria.

Predictors of Clinical Outcomes in Adult Laryngotracheal Stenosis.

Objectives: Sequelae of laryngotracheal stenosis (LTS) can be devastating, often necessitating tracheostomy. This study aims to describe the characteristics and outcomes of patients with LTS and identify risk factors for long-term tracheostomy dependence stratified by etiology.

Methods: A retrospective chart review was performed on 215 patients diagnosed with LTS from 09/01/2011 to 12/31/2020.

Improved survival for severely injured patients receiving massive transfusion at US teaching hospitals: A nationwide analysis.

Background: Previous studies have shown improved survival for patients treated at American College of Surgeons (ACS)-verified level I trauma centers compared with level II, level III, and undesignated centers. This mortality difference is more pronounced in severely injured patients. However, a survival benefit for severely injured trauma patients has not been established at teaching institutions compared with nonteaching centers.

Mechanical Property Comparison of 23-, 25-, and 27-Gauge Vitrectors across Vitrectomy Systems.

Objective: To investigate the mechanical properties of 23-, 25-, and 27-gauge vitrectomy vitrectors across 3 different vitrectomy systems to inform surgical techniques.

Design: An experimental study that did not involve any human subjects.

Methods: Nine vitrectors (3 each of 23-, 25-, and 27 gauge) from Alcon, Dutch Ophthalmic Research Center (DORC), and Bausch & Lomb (B/L) were measured.

Accidental Infant Suffocation and Strangulation in Bed: Disparities and Opportunities.

Objectives (a) Update previous descriptions of trends in ASSB; (b) determine if factors previously associated with ASSB are replicated by updated data; and (c) generate new hypotheses about the occurrence of ASSB and racial inequalities in ASSB mortality. Methods National Center for Health Statistics files (International Classification of Diseases, Tenth Edition) Code W75 to describe race-ethnicity-specific ASSB occurrence. Results (a) ASSB mortality continues to increase significantly; for 1999-2016, 4.
