Introduction: Despite its importance in voice training, comprehensive research into sustained vowel phonation with constant pitch and increasing and decreasing loudness, the so-called Messa di Voce, is lacking. The study examines the laryngeal behavior during Messa di Voce, regarding the impact of the speed of execution on voice stability parameters.

Materials And Methods: Nine untrained, healthy subjects (5 female, 4 male) were asked to perform Messa di Voce exercises on the vowel [i:], involving a gradual increase and decrease of volume.

Purpose: This study explores the effects of water intake and a hyaluronic acid (HA)-containing lozenge on acoustic measurements and vocal oscillation patterns investigated after a vocal loading test (VLT).

Method: Ten healthy subjects (five females, five males) read out loud a standardized text for 10 min at a target level of 80 dB(A), measured 30 cm from the mouth, under three conditions but each after fasting for 2 hr: (a) drinking 0.7 l of water, (b) sucking an HA-containing lozenge, and (c) neither of both before the VLT.

Background: Extracorporeal membrane oxygenation (ECMO) has emerged as a critical intervention in the management of patients with trauma-induced cardiorespiratory failure. This study aims to compare outcomes in patients with severe thoracic injuries with and without venovenous extracorporeal membrane oxygenation (VV-ECMO).

Methods: We performed a retrospective cohort study on Trauma Quality Improvement Program (2017-2021) and included all patients with isolated blunt thoracic injuries with Abbreviated Injury Scale score of ≥4 who required intubation.

Background: Rotator cuff repair (RCR) is a frequently performed outpatient orthopaedic surgery, with substantial financial implications for health-care systems. Time-driven activity-based costing (TDABC) is a method for nuanced cost analysis and is a valuable tool for strategic health-care decision-making. The aim of this study was to apply the TDABC methodology to RCR procedures to identify specific avenues to optimize cost-efficiency within the health-care system in 2 critical areas: (1) the reduction of variability in the episode duration, and (2) the standardization of suture anchor acquisition costs.

This project implemented Seguridad en las Lecherías, an award-winning, bilingual (Spanish and English), 5-module curriculum approved by the Occupational Safety and Health Administration. The intervention aimed to increase safety knowledge among immigrant dairy workers, encourage a safety culture, and identify challenges faced by the dairy farming community in Minnesota and South Dakota. A total of 360 Hispanic immigrant workers from 19 participating dairies were trained.
