Breaking down barriers: Call-taker strategies to address caller perception of inappropriateness of cardiopulmonary resuscitation during the emergency ambulance call.

Background: Ambulance call-takers perform the critical role of prompting callers to initiate and continue cardiopulmonary resuscitation (CPR) for patients with suspected out-of-hospital cardiac arrest (OHCA). This study aimed to identify call-taker strategies to address callers' perceptions of CPR 'inappropriateness' (perceiving the patient as dead and beyond help, or as showing signs of life).
Methods: Using a linguistic approach, we analysed 31 calls previously identified as having an inappropriateness barrier to CPR initiation or continuation.
An Anechoic, High-Fidelity, Multidirectional Speech Corpus.

Introduction: We currently lack speech testing materials faithful to broader aspects of real-world auditory scenes such as speech directivity and extended high frequency (EHF; > 8 kHz) content that have demonstrable effects on speech perception. Here, we describe the development of a multidirectional, high-fidelity speech corpus using multichannel anechoic recordings that can be used for future studies of speech perception in complex environments by diverse listeners.
Design: Fifteen male and 15 female talkers (21.
Gender and speech material effects on the long-term average speech spectrum, including at extended high frequencies.

Gender and language effects on the long-term average speech spectrum (LTASS) have been reported, but typically using recordings that were bandlimited and/or failed to accurately capture extended high frequencies (EHFs). Accurate characterization of the full-band LTASS is warranted given recent data on the contribution of EHFs to speech perception. The present study characterized the LTASS for high-fidelity, anechoic recordings of males and females producing Bamford-Kowal-Bench sentences, digits, and unscripted narratives.

The goal of this study is to demonstrate the feasibility of detecting symptom episodes in a free-living scenario, providing a higher level of interpretability to aid AI-powered decision-making. Machine learning models trained on wearable sensor data from scripted activities performed by participants in the lab and clinician ratings of the video recordings of these tasks identified tremor, bradykinesia, and dyskinesia in the supervised lab environment with a balanced accuracy of 83%, 75%, and 81%, respectively, when compared to the clinician ratings.

Background: Obesity is a common, serious and costly chronic disease. Current clinical practice guidelines recommend that providers augment the longitudinal care of people living with obesity with consistent support for the development of self-efficacy and motivation to modify their lifestyle behaviors. Lifestyle behavior change aligns with the goals of motivational interviewing (MI), a client-centered yet directive counseling modality.
