The Development of a Nano-based Approach to Alleviate Cisplatin-Induced Ototoxicity
Abstract
Cisplatin-induced hearing loss is experienced by a high percentage of patients with squamous cell carcinoma undergoing cisplatin chemotherapy. A novel nano-construct capable of sequestering extracellular cisplatin was developed to combat this problem. The nano-construct consisted of superparamagnetic iron oxide nanoparticles (SPIONs) entrapped within polymeric micelles, which were formed from a glutathione diethyl ester-conjugated amphiphilic diblock copolymer. The glutathione-micelles were analyzed at the cellular level and in an organotypic study for safety evaluation. All utilized methods indicated that the micelles do not cause cellular toxicity or organ damage. The micelles’ ability to reduce cisplatin-induced cytotoxicity was then probed in an in vitro model. Cisplatin was pre-treated with the novel nano-construct before being added to growing cells. When compared to cells that were exposed to untreated cisplatin, cells in the pre-treated cisplatin group showed a significant increase in cell viability. This clearly demonstrates that the construct is able to protect the cells from cisplatin cytotoxicity and makes it highly likely that the novel nano-construct will be able to play a role in the protection of the inner ear from cisplatin-induced ototoxicity.

Health care professionals' neckties as a source of transmission of bacteria to patients: a systematic review.
Health care professionals' neckties as a source of transmission of bacteria to patients: a systematic review.
CMAJ Open. 2018 Jan 12;6(1):E26-E30
Authors: Pace-Asciak P, Bhimrao SK, Kozak FK, Westerberg BD
Abstract
BACKGROUND: There is growing concern that neckties worn by health care professionals may contribute to infections contracted in health care settings. We evaluated the evidence for health-care-associated infections resulting from neckties and whether the evidence is sufficient to warrant a tieless policy in Canada.
METHODS: We performed a systematic review to determine whether neckties worn by health care professionals colonize harmful pathogenic bacteria and whether they contribute to the spread of infection to patients in the inpatient or outpatient setting. We searched PubMed (1966 to 2017) and Embase (1974 to 2017). The level of evidence was appraised according to the Oxford Centre for Evidence-Based Medicine levels of evidence. We evaluated the quality of evidence and the risk of bias using the Jadad scale or the Newcastle-Ottawa Scale.
RESULTS: We screened 1675 citations, of which 6 were ultimately included in the systematic review. Only 1 study gave level 1b evidence (randomized controlled trial). Neckties were more likely than shirt pockets to colonize bacteria. There is limited evidence that neckties may be contaminated with pathogenic bacteria (e.g., methicillin-resistant Staphylococcus aureus) and very limited evidence that contaminated neckties may transmit bacteria (in a controlled experimental setting to a mannequin).
INTERPRETATION: There is no evidence of increased rates of health-care-associated infections related to the wearing of neckties by health care professionals. There is weak evidence that neckties are contaminated with pathogenic (and nonpathogenic) bacteria. The level of evidence was weak and the studies were heterogeneous. Evidence to support the need for a tieless dress code policy is lacking.

Association of Chronic Subjective Tinnitus with Neuro- Cognitive Performance.
Int Tinnitus J. 2017 Dec 01;21(2):90-97
Authors: Gudwani S, Munjal SK, Panda NK, Kohli A
Abstract
INTRODUCTION: Chronic subjective tinnitus is associated with cognitive disruptions affecting perception, thinking, language, reasoning, problem solving, memory, visual tasks (reading) and attention.
OBJECTIVE: To evaluate existence of any association between tinnitus parameters and neuropsychological performance to explain cognitive processing.
MATERIALS AND METHODS: Study design was prospective, consisting 25 patients with idiopathic chronic subjective tinnitus and gave informed consent before planning their treatment. Neuropsychological profile included (i) performance on verbal information, comprehension, arithmetic and digit span; (ii) non-verbal performance for visual pattern completion analogies; (iii) memory performance for long-term, recent, delayed-recall, immediate-recall, verbal-retention, visualretention, visual recognition; (iv) reception, interpretation and execution for visual motor gestalt. Correlation between tinnitus onset duration/ loudness perception with neuropsychological profile was assessed by calculating Spearman's coefficient.
RESULTS: Findings suggest that tinnitus may interfere with cognitive processing especially performance on digit span, verbal comprehension, mental balance, attention & concentration, immediate recall, visual recognition and visual-motor gestalt subtests. Negative correlation between neurocognitive tasks with tinnitus loudness and onset duration indicated their association. Positive correlation between tinnitus and visual-motor gestalt performance indicated the brain dysfunction.
CONCLUSION: Tinnitus association with non-auditory processing of verbal, visual and visuo-spatial information suggested neuroplastic changes that need to be targeted in cognitive rehabilitation.

Balance Assessment in Deaf Children and Teenagers Prior to and Post Capoeira Practice through the Berg Balance Scale.
Int Tinnitus J. 2017 Dec 01;21(2):77-822
Authors: Lima R
Abstract
INTRODUCTION: Hearing loss changes the functionality and body structure a disability that limits activity and restricts the participation of the individual in situations of daily life. It is believed that capoeira can help people with visual disabilities to minimize these deficits. BSE is a low specificity scale that evaluates objectively and functionally aspects of balance and risk of falls in the elderly and children, including the effect of environment on balance function.
OBJECTIVE: The objective of the research is to analyze deaf children and adolescents prior to and post-practice of capoeira using the Berg Balance Scale (BBS).
METHODS: Quantitative, clinical and observational studies. Twenty five deaf children between 10 and 16 years old of both genders were assessed. BBS was applied in two stages: before starting capoeira and after 6 months of training. The one-hour classes were held once a week for quantitative evaluation purposes. The subjects were divided and evaluated in two groups (10-13 years old and 14-16 years old).
RESULTS: There was a significant statistical difference in BBS scores. The general group and the group of 10-13 years old (p = 0.0251) showed an increase in scores after practicing capoeira (p = 0.0039). There were no statistically significant differences in the group from 14 to 16 years of age (p = 0.0504).
CONCLUSION: Using the Berg Balance Scale, it was possible to observe an improvement in the balance of the group of children and adolescents who practiced capoeira, and consequently, a decrease in the risk of falling.

Effect of Elevated Intracranial Pressure on Amplitudes and Frequency Tuning of Ocular Vestibular Evoked Myogenic Potentials Elicited by Bone-Conducted Vibration.
Ear Hear. 2016 Nov/Dec;37(6):e409-e413
Authors: Gürkov R, Speierer G, Wittwer L, Kalla R
Abstract
OBJECTIVE: Recently, it could be demonstrated that an increased intracranial pressure causes a modulation of the air conducted sound evoked ocular vestibular evoked myogenic potential (oVEMP). The mechanism for this modulation is not resolved and may depend on a change of either receptor excitability or sound energy transmission.
DESIGN: oVEMPs were elicited in 18 healthy subjects with a minishaker delivering 500 and 1000 Hz tone bursts, in supine and tilted positions.
RESULTS: The study could confirm the frequency tuning of oVEMP. However, at neither stimulus frequency could a modulating effect of increased intracranial pressure be observed.
CONCLUSION: These data suggest that the observed modulation of the oVEMP response by an increased intracranial pressure is primarily due to the effect of an increased intralabyrinthine pressure onto the stiffness of the inner ear contents and the middle ear-inner ear junction. Future studies on the effect of intracranial pressure on oVEMP should use air-conducted sound and not bone-conducted vibration.

Long-term Average Spectra Analysis of Voice in Children With Cleft Palate
Source:Journal of Voice
Author(s): Zengjie Yang, Jincai Fan, Jia Tian, Liqiang Liu, Cheng Gan, Tiran Zhang, Zheng Liu, Bing Han
ObjectivesThe purpose of this study was to survey the spectral characteristics and to compare, using an acoustic analyzer, the objective data obtained from patients with cleft palates with the objective data of normal children using long-term average spectra (LTAS) analysis.MethodsParticipants were divided into a clinical group and a control group. All participants were asked to practice reading a sentence to become fluent. The duration of each recording was about 60 seconds. All samples were subjected to acoustic analysis using Praat software. All recordings were analyzed acoustically using LTAS.ResultsIn this study, there was no significant difference between the control group and the clinical group in the low-frequency region (boys: 0–2720 Hz; girls: 0–2240 Hz). LTAS measurements showed a great difference between the control group and the clinical group in the middle-frequency region (boys: 2720–4000 Hz; girls: 2240–4000 Hz). We also found that the energy distributed in the clinical group was lower than that of the control group in the high-frequency region (4000 Hz–8000 Hz) in both boys and girls.ConclusionsThe results reveal a lack of flat region in the middle-frequency range in the clinical group (both boys and girls) in comparison with the control group. The results also reveal that there is no significant difference across the control group and the clinical group in the low-frequency region.

Reliability and Validity of the Turkish Version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)
Source:Journal of Voice
Author(s): Esra Özcebe, Fatma Esen Aydinli, Tuğçe Karahan Tiğrak, Önal İncebay, Taner Yilmaz
ObjectivesThe main purpose of this study was to culturally adapt the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) to Turkish and to evaluate its internal consistency, validity, and reliability.Materials and MethodsThe Turkish version of CAPE-V was developed, and with the use of a prospective case-control design, the voice recordings of 130 participants were collected according to CAPE-V protocol. Auditory-perceptual evaluation was conducted according to CAPE-V and Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale by two ear, nose, and throat specialists and two speech and language therapists. The different types of voice disorders, classified as organic and functional disorders, were compared in terms of their CAPE-V scores.ResultsThe overall severity parameter had the highest intrarater and inter-reliability values for all the participants. For all four raters, the differences in the six CAPE-V parameters between the study and the control groups were found to be statistically significant. Among the correlations for the comparable parameters of the CAPE-V and the GRBAS scales, the highest correlation was found between the overall severity-grade parameters. There was no difference found between the organic and functional voice disorders in terms of the CAPE-V scores.ConclusionsThe Turkish version of CAPE-V has been proven to be a reliable and valid instrument to use in the auditory-perceptual evaluation of voice. For the future application of this study, it would be important to investigate whether cepstral measures correlate with the auditory-perceptual judgments of dysphonia severity collected by a Turkish version of the CAPE-V.

Trends in Singing Voice Research: An Innovative Approach
Source:Journal of Voice
Author(s): Pedro Melo Pestana, Vaz Freitas Susana, Maria Conceição Manso
ObjectivesThe objectives of this study were to trace and describe research patterns in singing voice, to compare the amount of published research over time, to identify journals that published most papers on “singing voice,” and to establish the most frequent research topics.Materials and MethodsThe study uses qualitative and quantitative approaches through descriptive statistics, text mining, and clustering. The authors conducted a search to identify scientific papers. The titles and abstracts were analyzed regarding word frequency and relations between them, through hierarchical cluster analysis and co-occurrence networks. The frequency of journals was calculated, as well as the amount of papers across time.ResultsSince 1949, 754 papers were published and an increase was noticed. Even though 162 journals were identified by the authors, the Journal of Voice holds the majority of papers, in every analyzed period. An evolution of studied topics is described. Up to 2010, the main theme was professional singers, especially classical and opera interpreters. Since then, voice quality and the effects of training gathered more attention.ConclusionsThe growing interest in singing has been conspicuous since the first indexed paper. However, it has been slightly slowing down. Until 2010, great importance was given to the voice quality of singers and their occupational demands. Acoustic analysis was widely used to study the effects of training. Since 2010, the concern with functionality is increasing, rather than the organic voice structures. Musical perception studies have been a trend, as well as the use of electroglottography.

Effect of Auditory-Perceptual Training With Natural Voice Anchors on Vocal Quality Evaluation
Source:Journal of Voice
Author(s): Priscila Campos Martins dos Santos, Maurílio Nunes Vieira, João Pedro Hallack Sansão, Ana Cristina Côrtes Gama
PurposeTo analyze the effects of auditory-perceptual training with anchor stimuli of natural voices on inter-rater agreement during the assessment of vocal quality.Study designThis is a quantitative nature study.MethodsAn auditory-perceptual training site was developed consisting of Programming Interface A, an auditory training activity, and Programming Interface B, a control activity. Each interface had three stages: pre-training/pre-interval evaluation, training/interval, and post-training/post-interval evaluation. Two experienced evaluators classified 381 voices according to the GRBASI scale (G-grade, R-roughness, B-breathiness, A-asthenia, S-strain, I-instability). Voices were selected that received the same evaluation by both evaluators: 57 voices for evaluation and 56 for training were selected, with varying degrees of deviation across parameters. Fifteen inexperienced evaluators were then selected. In the pre-, post-training, pre-, and postinterval stages, evaluators listened to the voices and classified them via the GRBASI scale. In the stage interval evaluators read a text. In the stage training each parameter was trained separately. Evaluators analyzed the degrees of deviation of the GRBASI parameters based on anchor stimuli, and could only advance after correctly classifying the voices. To quantify inter-rater agreement and provide statistical analyses, the AC1 coefficient, confidence intervals, and percentage variation of agreement were employed.ResultsExcept for the asthenia parameter, decreased agreement was observed in the control condition. Improved agreement was observed with auditory training, but this improvement did not achieve statistical significance.ConclusionTraining with natural voice anchors suggest an increased inter-rater agreement during perceptual voice analysis, potentially indicating that new internal references were established.

Evaluation of a Shorter Follow-up Time to Capture Benefit of a Trial Vocal Fold Augmentation
Source:Journal of Voice
Author(s): Thomas L. Carroll, Elizabeth Faudoa, Maxine Van Doren
ObjectiveTrial vocal fold injection (TVFI) is employed diagnostically for patients with subtle glottic insufficiency to explore potential for improvement. Clinical experience demonstrates the time to and length of peak benefit of the TVFI is variable. Previous studies collected data 4 weeks or more after TVFI. The aim of this study was to compare subjectively successful and unsuccessful TVFI patient groups. It is hypothesized that patients with subjectively reported success will also have significant improvements in Voice Handicap Index-10 (VHI-10), phase closure percentage, and aerodynamic measures 2 weeks after trial augmentation.Methods/DesignSubjects with glottic insufficiency were included in this retrospective review if they underwent office-based, per-oral vocal fold injection augmentation specifically for trial purposes. Patients were divided into “successful” and “unsuccessful” groups based on their subjective experience during the 2-week post-TVFI period. VHI-10, subjective report, phase closure evaluation using frame-by-frame analysis, and aerodynamic data were collected pre- and 2 weeks post-TVFI.ResultsOf the subjects, 15 of 23 (65%) reported a successful subjective improvement of their symptom, whereas 8 (35%) were unsuccessful (only partial improvement or no improvement). The number of subjects with an improvement in VHI-10 by 5 or more points was not significantly different between groups. The number of subjects that demonstrated complete, long phase closure was significantly higher in the successful group (P = 0.021).ConclusionsThe understanding of how to more precisely determine the success of TVFI remains incomplete. Subjective improvement of successful TVFI was captured with basic clinical questioning, yet the VHI-10 was unable to confidently demonstrate this reported success 2 weeks after TVFI.

OBJECTIVE: To characterize the audiometric phenotype of autosomal-dominant DFNA34 hearing loss (HL) caused by a missense substitution in the NLRP3 gene. NLRP3 encodes a critical component of the NLRP3 inflammasome that is activated in innate immune responses.
STUDY DESIGN: This study was conducted under protocol 01-DC-0229 approved by the NIH Combined Neurosciences IRB. We performed medical and developmental history interviews and physical and audiological examinations of affected individuals with DFNA34 HL caused by the p.Arg918Gln mutation of NLRP3. We retrospectively reviewed audiological reports, when available, from other health care centers.
SETTING: Federal biomedical research facility.
SUBJECTS: Eleven members of a North American family segregating p.Arg918Gln.
MAIN OUTCOME MEASURES: Pure-tone thresholds, rates of pure-tone threshold progression, and speech discrimination scores.
RESULTS: Eight subjects had bilateral sensorineural HL with an onset in the late 2nd to 4th decade of life. Slowly progressive HL initially primarily affected high frequencies. Low and middle frequencies were affected with advancing age, resulting in moderate HL with a downsloping audiometric configuration. The average annual threshold deterioration was 0.9 to 1.5 dB/yr. Speech recognition scores ranging from 60 to 100% were consistent with cochlear, but not retrocochlear, etiology. Three subjects (16, 22, and 32 yr old) had normal hearing thresholds.
CONCLUSION: DFNA34 HL has an onset during early adulthood and progresses approximately 1.2 dB/yr.

Abstract
Age-related hearing loss (ARHL), clinically referred to as presbycusis, is one of the three most prevalent chronic medical conditions of our elderly, with the majority of persons over the age of 60 suffering from some degree of ARHL. The progressive loss of auditory sensitivity and perceptual capability results in significant declines in workplace productivity, quality of life, cognition and abilities to communicate effectively. Aldosterone is a mineralocorticoid hormone produced in the adrenal glands and plays a role in the maintenance of key ion pumps, including the Na-K(+)-Cl co-transporter 1 or NKCC1, which is involved in homeostatic maintenance of the endocochlear potential. Previously we reported that aldosterone (1 μM) increases NKCC1 protein expression in vitro and that this up-regulation of NKCC1 was not dose-dependent (dosing range from 1 nM to 100 μM). In the current study we measured behavioral and electrophysiological hearing function in middle-aged mice following long-term systemic treatment with aldosterone. We also confirmed that blood pressure remained stable during treatment and that NKCC1 protein expression was upregulated. Pre-pulse inhibition of the acoustic startle response was used as a functional measure of hearing, and the auditory brainstem response was used as an objective measure of peripheral sensitivity. Long-term treatment with aldosterone improved both behavioral and physiological measures of hearing (ABR thresholds). These results are the first to demonstrate a protective effect of aldosterone on age-related hearing loss and pave the way for translational drug development, using aldosterone as a key component to prevent or slow down the progression of ARHL.
