Rates of Detecting Thyroid Nodules Recommended for Biopsy with Ultrasound: Are All Indications Equal?

The use of thyroid ultrasound increases yearly, adding to costs and overdetection of clinically irrelevant nodules. We investigated which indications most commonly prompt referral for thyroid ultrasound and the diagnostic utility by indication. We performed a retrospective observational cohort study of adults (≥18 years) undergoing an initial dedicated thyroid ultrasound between 2017 and 2019 at a tertiary academic center.

Measuring the impact of simulation debriefing on the practices of interprofessional trauma teams using natural language processing.

Background: Natural language processing (NLP) may be a tool for automating trauma teamwork assessment in simulated scenarios.

Methods: Using the Trauma Nontechnical Skills Assessment (T-NOTECHS), raters assessed video recordings of trauma teams in simulated pre-debrief (Sim1) and post-debrief (Sim2) trauma resuscitations. We developed codes through directed content analysis and created algorithms capturing teamwork-related discourse through NLP.

A Rare Complication of Fine-Needle Aspiration of Neck Structures.

Fine-needle aspiration (FNA) is a generally accepted tool for safe diagnostic evaluation in the workup of lesions and masses. Aside from the commonly discussed risks of infection and minor bleeding related to skin puncture, other more serious complications have been reported sparingly. We present two cases of pneumothorax from FNA of neck structures, which have been theorized but not previously reported to our knowledge.

Thermoacoustic range verification using a clinical ultrasound array provides perfectly co-registered overlay of the Bragg peak onto an ultrasound image.

The potential of particle therapy due to focused dose deposition in the Bragg peak has not yet been fully realized due to inaccuracies in range verification. The purpose of this work was to correlate the Bragg peak location with target structure, by overlaying the location of the Bragg peak onto a standard ultrasound image. Pulsed delivery of 50 MeV protons was accomplished by a fast chopper installed between the ion source and the cyclotron inflector.
