Article Abstract
Objectives/hypothesis: To determine if the Vocal Priorities Questionnaire (VPQ) could be used in people who were not seeking treatment for a voice problem. To determine if the VPQ could be used to compare groups based on self-reported voice problems. To determine if vocal priorities (loudness, clarity, pitch, pitch range) vary based on self-reported voice problems.
Study Design: Prospective cross-sectional study.
Methods: An online survey that contained demographic questions, questions about self-reported voice problems, and the VPQ was distributed to undergraduate university students. Confirmatory factor analyses (CFA) and exploratory factor analysis (EFA) were completed to determine if the VPQ was appropriate for use in this population. Invariance testing determined if the VPQ could be used to compare groups. Cronbach's alpha determined internal consistency. An analysis of variance was conducted to compare the scores for each vocal priority across three self-reported voice problem categories: never, current, and past.
Results: Responses from 285 participants were analyzed. An initial CFA found that the four-priority VPQ originally proposed did not have adequate fit indices. An EFA and modified CFA revealed that four priorities were still present, but "not having a gravelly voice" fit better with the priority of pitch, not clarity. With this model, invariance was verified and Cronbach's alpha indicated internal consistency. Loudness was the top vocal priority for 34.8%. In those with a past voice problem, clarity was scored higher compared to those with a current voice problem, F(2, 284) = 5.298, P = 0.006, and pitch range was scored higher compared to those who had never experienced a voice problem, F(2, 284) = 5.431, P = 0.005.
Conclusions: A modified four-priority version of the VPQ presented with acceptable dimensionality and invariance for college students with and without self-reported voice problems. Scores for clarity and pitch range were influenced by experiences with voice problems.

A reconfigurable piezo-ionotropic polymer membrane for sustainable multi-resonance acoustic sensing.
Nat Commun

Sensorineural hearing loss is the most common form of deafness, typically resulting from the loss of sensory cells on the basilar membrane, which cannot regenerate and thus lose sensitivity to sound vibrations. Here, we report a reconfigurable piezo-ionotropic polymer membrane engineered for biomimetic sustainable multi-resonance acoustic sensing, offering exceptional sensitivity (530 kPa) and broadband frequency discrimination (20 Hz to 3300 Hz) while remaining resistant to "dying". The acoustic sensing capability is driven by an ion hitching-in cage effect intrinsic to the ion gel combined with fluorinated polyurethane.

Introduction: The preservation of the human self-a fundamental yet underexplored aspect of neurosurgical practice-has gained increasing attention in recent years.
Research Question: How can neural correlates of self-consciousness be identified, monitored, and protected during brain tumor surgery, and how might this reshape the concept of "onco-functional balance"?
Material And Methods: This review synthesizes emerging evidence from neuroimaging, neuropsychology, and intraoperative neurophysiology to build a framework for integrating the concept of self into modern neurosurgical practice.
Results: We describe the anatomical and functional basis of bodily and cognitive self-awareness, highlighting the roles of interoception, multisensory integration, and higher-order cortical networks such as the medial prefrontal cortex, insula and temporoparietal junction.
Effectiveness and Implementation of a One-Day Voice Preventive Program for Primary-School Teachers: A Longitudinal Study Based on Acoustic and Subjective Evaluations.

A longitudinal study was conducted over 5 months on 22 primary school teachers without existing vocal disorders to assess the effectiveness of a 1-day preventive voice intervention in limiting vocal deterioration over the school year, improving vocal endurance throughout a workday, and promoting the adoption and maintenance of healthy vocal habits. A combined analysis of the variation of objective acoustic parameters [f, Jitter, Shimmer, and harmonic to noise ratio (HNR)] throughout a workday showed that the intervention group (TEST) maintained a typical endurance profile across the school year, while the control group (CTRL) exhibited increased atypical vocal responses. Subjective assessments further supported the preventive impact, with the TEST group reporting reduced vocal discomfort and communication difficulties immediately after the intervention.

Objective: To investigate differences between the structural aspects and laryngeal functionality before and after a vocal loading activity and their association with symptoms of vocal fatigue (VF).
Methods: Young adults without vocal complaints and who use professional or nonprofessional voices participated in the research. Videolaryngostroboscopy (VLS) exams were performed before and after a vocal loading activity to which the participants were submitted, characterized by reading texts at high vocal intensity lasting 90 minutes.
