[Ab] Abstract:BACKGROUND: The doctoral viva voce is an under-researched field, particularly from the point of view of doctoral candidates. With increasing numbers of health care professionals undertaking doctoral study, we can develop practice by listening to their 'living voices'. OBJECTIVE: To explore doctoral candidates' experiences of their viva. DESIGN AND METHODS: Using exploratory research and purposive sampling, eighteen participants who had undergone examination of their doctorate within the last five years were identified. Semi-structured interviews were used to explore these participants' experiences of their viva. RESULTS: Thematic analysis of the data demonstrated that: Candidates wanted to engage in academic argument but were not always provided the opportunity to do so; the viva voce examination was frequently an emotional experience, even for candidates who did not regard themselves as subject to such emotions, examiners were sometimes able to moderate the effect of these emotions; practical aspects of the examination were not always considered; issues of fairness were raised, both by successful candidates and by those who were required to resubmit. CONCLUSIONS: The viva voce examination, as experienced by candidates, is not always a fair one. We recommend engagement of the academic community to promote best practice in the "living voice" examination.

[Ab] Abstract:Introduction: Medical equipment is an essential health intervention tool used by nurses for prevention, diagnosis and treatment of disease and for rehabilitation of patients. However, access to functioning medical equipment is a challenge in low- and middle-income countries. The World Health Organization estimated that 50 to 80 percent of medical equipment in developing countries is not working, creating a barrier to the ability of the health system to deliver health services to patients. This study explored and described the lived experiences of nurses working at a district hospital with a critical shortage of medical equipment. Methods: A qualitative, exploratory, phenomenological and descriptive study design was used. A purposive sampling was used to select participants and due to saturation of data 14 nurses participated in the study. Research ethics were observed. Data was collected through semi-structured interviews using an interview guide. Interviews were audio-taped and field notes were taken. Voice recordings were transcribed verbatim and Tesch's open coding method was used for data analysis. Findings were confirmed by an independent coder. Results: Critical shortage of medical equipment at the hospital occurred in the form of unavailability of equipment, low quality and poor maintenance of the few that were available. Shortage impacted negatively on nursing care, nursing profession and the hospital. Conclusion: Nurses should be provided with functional medical equipment in order to provide quality nursing care. Management, leadership and governance structures should be strengthened to ensure that procurement and maintenance plans for medical equipment are developed and implemented.

[Ab] Abstract:This study was inspired by the case of a robbery victim who was startled and reminded of the crime upon hearing a stranger's voice, while not clearly recognizing the speaker. To investigate whether specific voices can modulate startle reactions and thereby predict speaker identification, we presented an audio hijack scenario to 84 participants and afterwards asked them to identify the perpetrator among neutral and negative speech fragments, while measuring flash-evoked eye-blink startle responses. Furthermore, we addressed data-driven cognitive processing during the audio scenario as a potential moderator in voice discrimination. Negative speech and the perpetrator's voice led to potentiated startle. Enhanced startle was positively associated with voice discrimination, but only in neutral speech fragments. In negative fragments, this association was weakened as a function of self-reported levels of data-driven processing during encoding. Thus, startle responses can generally predict accurate voice recognition, but speech emotionality and cognitive processing moderate this relationship.

[Ab] Abstract:Previously, we have shown that people who have had one eye surgically removed early in life during visual development have enhanced sound localization [1] and lack visual dominance, commonly observed in binocular and monocular (eye-patched) viewing controls [2]. Despite these changes, people with one eye integrate auditory and visual components of multisensory events optimally [3]. The current study investigates how people with one eye perceive the McGurk effect, an audiovisual illusion where a new syllable is perceived when visual lip movements do not match the corresponding sound [4]. We compared individuals with one eye to binocular and monocular viewing controls and found that they have a significantly smaller McGurk effect compared to binocular controls. Additionally, monocular controls tended to perceive the McGurk effect less often than binocular controls suggesting a small transient modulation of the McGurk effect. These results suggest altered weighting of the auditory and visual modalities with both short and long-term monocular viewing. These results indicate the presence of permanent adaptive perceptual accommodations in people who have lost one eye early in life that may serve to mitigate the loss of binocularity during early brain development.

[Ab] Abstract:BACKGROUND: Patient-reported measure (PRM) questionnaires were originally used in research to measure outcomes of intervention studies. They have now evolved into a diverse family of tools measuring a range of constructs including quality of life and experiences of care. Current health and social care policy increasingly advocates their use for embedding the patient voice into service redesign through new models of care such as person-centered coordinated care (P3C). If chosen carefully and used efficiently, these tools can help improve care delivery through a variety of novel ways, including system-level feedback for health care management and commissioning. Support and guidance on how to use these tools would be critical to achieve these goals. OBJECTIVE: The objective of this study was to develop evidence-based guidance and support for the use of P3C-PRMs in health and social care policy through identification of PRMs that can be used to enhance the development of P3C, mapping P3C-PRMs against an existing model of domains of P3C, and integration and organization of the information in a user-friendly Web-based database. METHODS: A pragmatic approach was used for the systematic identification of candidate P3C-PRMs, which aimed at balancing comprehensiveness and feasibility. This utilized a number of resources, including existing compendiums, peer-reviewed and gray literature (using a flexible search strategy), and stakeholder engagement (which included guidance for relevant clinical areas). A subset of those candidate measures (meeting prespecified eligibility criteria) was then mapped against a theoretical model of P3C, facilitating classification of the construct being measured and the subsequent generation of shortlists for generic P3C measures, specific aspects of P3C (eg, communication or decision making), and condition-specific measures (eg, diabetes, cancer) in priority areas, as highlighted by stakeholders. RESULTS: In total, 328 P3C-PRMs were identified, which were used to populate a freely available Web-based database. Of these, 63 P3C-PRMs met the eligibility criteria for shortlisting and were classified according to their measurement constructs and mapped against the theoretical P3C model. We identified tools with the best coverage of P3C, thereby providing evidence of their content validity as outcome measures for new models of care. Transitions and medications were 2 areas currently poorly covered by existing measures. All the information is currently available at a user-friendly web-based portal (p3c.org.uk), which includes all relevant information on each measure, such as the constructs targeted and links to relevant literature, in addition to shortlists according to relevant constructs. CONCLUSIONS: A detailed compendium of P3C-PRMs has been developed using a pragmatic systematic approach supported by stakeholder engagement. Our user-friendly suite of tools is designed to act as a portal to the world of PRMs for P3C, and have utility for a broad audience, including (but not limited to) health care commissioners, managers, and researchers.

[Ab] Abstract:Recognizing the identity of others by their voice is an important skill for social interactions. To date, it remains controversial which parts of the brain are critical structures for this skill. Based on neuroimaging findings, standard models of person-identity recognition suggest that the right temporal lobe is the hub for voice-identity recognition. Neuropsychological case studies, however, reported selective deficits of voice-identity recognition in patients predominantly with right inferior parietal lobe lesions. Here, our aim was to work towards resolving the discrepancy between neuroimaging studies and neuropsychological case studies to find out which brain structures are critical for voice-identity recognition in humans. We performed a voxel-based lesion-behaviour mapping study in a cohort of patients (n = 58) with unilateral focal brain lesions. The study included a comprehensive behavioural test battery on voice-identity recognition of newly learned (voice-name, voice-face association learning) and familiar voices (famous voice recognition) as well as visual (face-identity recognition) and acoustic control tests (vocal-pitch and vocal-timbre discrimination). The study also comprised clinically established tests (neuropsychological assessment, audiometry) and high-resolution structural brain images. The three key findings were: (i) a strong association between voice-identity recognition performance and right posterior/mid temporal and right inferior parietal lobe lesions; (ii) a selective association between right posterior/mid temporal lobe lesions and voice-identity recognition performance when face-identity recognition performance was factored out; and (iii) an association of right inferior parietal lobe lesions with tasks requiring the association between voices and faces but not voices and names. The results imply that the right posterior/mid temporal lobe is an obligatory structure for voice-identity recognition, while the inferior parietal lobe is only a facultative component of voice-identity recognition in situations where additional face-identity processing is required.

[Ab] Abstract:OBJECTIVE: Professional singers are more likely to develop laryngeal pathologies and symptoms associated with misuse and overuse of the voice. However, different studies have shown conflicting evidence. We aim to perform a systematic review and quantitative meta-analysis to determine the prevalence and risk of laryngeal pathologies and symptoms among professional singers. METHODS: Four electronic databases (MEDLINE, PubMed, EMBASE, and CINAHL) were searched, with no language restrictions. From 3368 potential studies, a total of 21 studies met our inclusion criteria. A systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. All cohort, case-control, or cross-sectional studies that reported the risk of laryngeal pathologies in singers were included. Data were pooled by a random effects model and the pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS: There was a positive relationship between singing and laryngeal pathologies. There was an increased risk of hoarseness (OR: 2.00, 95% CI: 1.61-2.49), gastroesophageal reflux disease (GERD) (OR: 1.45, 95% CI: 1.19-1.77), Reinke edema (OR: 2.15, 95% CI: 1.08-4.30), and polyps (OR: 2.10, 95% CI: 1.06-4.14) in professional singers. CONCLUSION: Professional singers are at an increased risk of laryngeal pathologies and symptoms associated with vocal misuse and overuse, particularly hoarseness, GERD, edema, and polyps.

[Ab] Abstract:An electrolarynx (EL) is one of the most popular voice rehabilitation technologies used after laryngectomy. However, most ELs generate monotonic EL speech, which has been shown to create a particular deficit in speech intelligibility, especially for Chinese Mandarin (Mandarin). Mandarin is a tonal language that makes lexical distinctions using variations in tone. Our purpose is to design an EL that can produce the four Mandarin tones, and to evaluate its performance. We designed a fundamental frequency (F0) control method for Mandarin EL speech and manufactured a touch-controlled electrolarynx (T-EL) prototype. Using monosyllables, disyllabic words, and frequently used phrases, we evaluated speech produced with a T-EL, as well as with monotone (M-EL) and variable-frequency modes (P-EL) of a commercially available TruTone EL. A male native Mandarin speaker with laryngectomy volunteered to be the speaker. Results show that the normal speech pitch contours of the four Mandarin tones were most closely matched by the characteristics produced with T-EL. The statistical accuracy of the T-EL's tone and word perception was significantly higher than that of the other EL types. Moreover, the confusion matrix indicates that the listeners could correctly identify the tones of monosyllables and disyllabic words in T-EL speech. Accurate tone judgment can improve the intelligibility of EL speech in Mandarin. The mean opinion score was used to evaluate the listeners' acceptability of EL speech. The scores of the T-EL and M-EL were very close, and the score of the P-EL was significantly lower than that of the other two ELs. However, the results from a single speaker cannot provide sufficient data to conclude which EL has a higher acceptability. The evaluation of multiple EL speakers with different EL types at difference levels of proficiency should be studied in future research.

[Ab] Abstract:CONTEXT: - Augmented reality (AR) devices such as the Microsoft HoloLens have not been well used in the medical field. OBJECTIVE: - To test the HoloLens for clinical and nonclinical applications in pathology. DESIGN: - A Microsoft HoloLens was tested for virtual annotation during autopsy, viewing 3D gross and microscopic pathology specimens, navigating whole slide images, telepathology, as well as real-time pathology-radiology correlation. RESULTS: - Pathology residents performing an autopsy wearing the HoloLens were remotely instructed with real-time diagrams, annotations, and voice instruction. 3D-scanned gross pathology specimens could be viewed as holograms and easily manipulated. Telepathology was supported during gross examination and at the time of intraoperative consultation, allowing users to remotely access a pathologist for guidance and to virtually annotate areas of interest on specimens in real-time. The HoloLens permitted radiographs to be coregistered on gross specimens and thereby enhanced locating important pathologic findings. The HoloLens also allowed easy viewing and navigation of whole slide images, using an AR workstation, including multiple coregistered tissue sections facilitating volumetric pathology evaluation. CONCLUSIONS: - The HoloLens is a novel AR tool with multiple clinical and nonclinical applications in pathology. The device was comfortable to wear, easy to use, provided sufficient computing power, and supported high-resolution imaging. It was useful for autopsy, gross and microscopic examination, and ideally suited for digital pathology. Unique applications include remote supervision and annotation, 3D image viewing and manipulation, telepathology in a mixed-reality environment, and real-time pathology-radiology correlation.

[Ab] Abstract:PURPOSE: To compare vocal and acoustic parameters of HIV-infected children and non-HIV-infected children. METHODS: Vocal samples were submitted to auditory-perceptual and acoustic analysis. Samples of the sustained vowel /ε/ and continuous speech of 74 children between 6 and incomplete 12 years old were analyzed, divided into two groups: 37 HIV-infected children (GHIV) and 37 non-HIV-infected children, the control group (CG), age and gender-matched and without previous vocal evaluation; they were all prepubescent by the Tanner Stages (MS, 2014). The children had their voices recorded and analyzed by VoxMetria 5.1, in the period between 2014 and 2015. The auditory-perceptual analysis assessed the overall degree of the vocal quality and was performed using a 100-point visual analogue scale, transformed into a 4 point numerical scale (0 = no vocal deviation and 4 = severe vocal deviation). The acoustic evaluation was based on the analysis of the vocal sample distribution in the Phonatory Deviation Diagram (PDD). The research was approved by the Ethics Committee under the number 122.746. RESULTS: In the auditory-perceptual analysis, most children of both groups were evaluated as with no vocal deviation. No difference between the groups was found in the acoustic analysis using the PDD; most voice samples were within the normality area, in the quadrant 1, with a spread density distribution and a vertical shape. CONCLUSION: HIV-infected children presented similar vocal quality to children without the illness, both for the perceptual-auditory and acoustic evaluation.
