The auditory rehabilitation mechanism with cochlear implants can activate specific cortical regions of the brain similar to those of hearing people. Near-infrared spectroscopy (fNIRS) is a neuroimaging tool that makes it possible to evaluate the cortical development of implanted children.

Objective: To investigate the molecular imaging response, reflected by difference in cortical oxygenation, in a deaf child with a cochlear implant compared to hearing children, observe and report auditory performance verifying correspondence with fNIRS findings.

Methods: Comparative case study using the fNIRS technique to evaluate the child's cortical activation on the day of device activation with three hearing children of the same hearing age. The recorded data was processed with Brainstorm software and statistical analysis was performed with the Power F test in relation to the baseline and the Permutation test for comparison. Longitudinal analysis of the implanted child's audiological data was carried out, as well as auditory perception and language questionnaires.

Results: No statistical differences were found between cortical activation of the implanted child and hearing children of the same hearing age. An improvement in the child's auditory perception and language performance can be observed after using the implant.

Conclusion: The evolution of auditory responses was observed, showing cortical maturation after activation of the cochlear implant seen in the molecular image, concomitantly with the use of hearing aids and speech therapy. It was observed that fNIRS is a neuroimaging technique capable of recording cortical changes in children with and without implants, being a promising tool.

The objective was to compare gesture-vocal synchrony in language functioning between mothers and babies and the gestural typology of babies from 3 to 26 months of age, one of them with autism spectrum disorder (case R), diagnosed at age 3, and the other without diagnosis (case B). It was select moments in which there was greater mother-baby interaction, from a bank of mother-baby interactions footage, from 3 to 26 months. It was analyzed using the Eudico Linguistic Annotator software ( ELAN), considering multimodal categories of sign language and speech of mothers and babies for descriptive statistical analysis. The results showed differences in the frequencies and types of gestures between the babies and also in the synchrony between them and their mothers. In the case of B., the gesture-vocal synchrony and variety of gestures is inserted in a context of conjunction between him and his mother in the first year of life, which gave rise to the second enunciative mechanism in the second year of life. In case R, the conjunction relationships were not established, as the difficulties in reading discomfort and annoyance gestures, very present in the baby since its first months of life, hindered the engagement and shared attention of the mother and her baby, disfavoring the inscription of gesture as language. R. showed language acquisition delay at 26 months. Although the gestural typology of B and R are similar, the frequencies, the quality and, above all, the gesture-vocal synchrony differ between dyads.

Purpose: To translate and cross-culturally adapt The Cancer Dyspnoea Scale - CDS into Brazilian Portuguese.

Methods: The original instrument in English was translated by a Brazilian Speech-Language Pathologist (SLP) and a Brazilian translator, both bilingual. The compiled version of the two translations was back-translated by a second SLP and a second translator, both bilingual, native English speakers, and fluent in Brazilian Portuguese. The final version was analyzed by a committee of experts, resulting in the final version of the Escala de Dispneia Oncológica - CDS-Br. It was pre-tested by applying the translated scale (with the additional option of responding "not applicable") to 40 cancer patients with dyspnea complaints - 35 initial participants and another five to confirm subsequent adjustments.

Results: None of the 35 initial study participants marked "not applicable" in the 12 scale items, but some questions were raised regarding the response keys, which were adapted after the committee of experts rediscussed them. Five new participants then responded to the scale to confirm the adjustments, without the need for further adaptations in the formulation of the items.

Conclusion: The translated and cross-culturally adapted version for Brazilian Portuguese was called Escala de Dispneia Oncológica - CDS-Br. Adjustments were necessary during translation and cross-cultural adaptation to reflect the original version and be compatible with the target language and culture. The Escala de Dispneia Oncológica - CDS-Br proved to be an easy-to-apply and understand self-assessment tool for dyspnea in cancer patients.

Purpose: To estimate the occurrence and characteristics of eating difficulties in Brazilian children.

Methods: Cross-sectional study, carried out from January to June 2022 through the completion of online forms and scales by parents and/or guardians of Brazilian children aged 6 months to 6 years and 11 months old.

Results: The sample included 596 participants, the majority (54.5%) of whom were male, with a gestational age at birth of an average of 38 weeks (SD = 3.07). Eating difficulties were present in 26% of the sample, being more prevalent in males (59.36%). There were positive associations between family education and the presence and severity of eating difficulties. The presence of at least one disease or comorbidity was reported in 59.1% (n = 352) of the sample, with severe eating difficulties being associated with the presence of at least one of the mentioned comorbidities. Children diagnosed with autism spectrum disorder were significantly associated with severe eating difficulties (p = <0.001). The presence of some syndrome or genetic disease was associated (p = 0.021) with moderate eating difficulties. There was a significant association (p = 0.026) between the presence of mild and moderate eating difficulties and the presence of more than one hospitalization.

Conclusion: The occurrence of eating difficulties in Brazilian children is 26%, the majority of which are severe and associated with pre-existing comorbidities.

Purpose: To evaluate the usability of a device for lip strength and mobility rehabilitation, combining exercises with digital games, and to examine the influence of age, muscle tension, and the number of attempts on the performance of adults and children.

Methods: This observational, cross-sectional study included 11 adults and nine children. Participants used a device consisting of an anatomical-functional prototype for the rehabilitation of the orbicularis oris muscle, which works as a controller for digital games and is activated by the counter-resistance movement performed by the lips. Participants played a game with the device and received a score proportional to their performance. After using the game, adult participants completed the System Usability Scale (SUS) to assess the device's usability. Participants' scores were compared based on age, lip muscle tension, and the number of attempts.

Results: Usability was considered good, with a mean score of 91.1 and a standard deviation of 11 points. There was no difference in scores across different attempts or between the scores of adults under and over 22 years old or children with normal and reduced lip tension. A statistically significant difference was found between adults' and children's scores in the first attempt and the mean of the attempts.

Conclusion: The device demonstrated good usability, with age (adults vs. children) influencing participant scores.

Purpose: To analyze the results of the Central Auditory Processing Disorder. Central Auditory Processing Skill Self-Perception Scale (CAPSSPS) and compare different auditory skills in young adults with and without Central Auditory Processing Disorder (CAPD).

Methods: Cross-sectional and prospective study. Thirty-two individuals participated in the study, who were native Brazilian Portuguese speakers, non-bilingual, non-musicians, and not exposed to noise, with normal results in basic audiological assessments, no cognitive or otological complaints, with or without difficulties related to Central Auditory Processing, divided into two groups: participants without CAPD (G1) and participants with CAPD (G2). All participants underwent Anamnesis, Visual Inspection of the External Auditory Canal, Pure Tone Audiometry, Speech Audiometry, Acoustic Immittance Measures, Behavioral Tests of Central Auditory Processing, and the CAPSSPS questionnaire.

Results: There was a significant difference between the groups with and without CAPD when comparing the CAPSSPS questionnaire and the Test of Frequency Pattern (TPF) - Auditec, Masking Level Difference (MLD), and the Gaps in Noise (GIN) tests for the left ear.

Conclusions: The CAPSSPS questionnaire demonstrated the possibility of screening for other altered auditory skills, in addition to auditory closure and temporal resolution in young adult populations, including temporal ordering for frequency and binaural interaction. Furthermore, young adult individuals showed greater alterations in auditory skills of temporal resolution, temporal ordering for frequency, and poorer performance in binaural interaction skill.

Purpose: To determine whether lifestyle habits influence the self-perception of cardiac symptoms and dizziness in patients with heart failure.

Methods: This is a cross-sectional, retrospective, analytical study approved by the Research Ethics Committee (approval no. 4,462,519). The study analyzed 34 medical records of patients with a functional diagnosis of peripheral vestibular dysfunction, followed up at a cardiology outpatient clinic, collecting data on sex, age, body mass index, and lifestyle habits such as smoking, alcohol consumption, nutritional monitoring, and regular physical activity. It also analyzed scores from the Dizziness Handicap Inventory (DHI) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ). The data were subjected to inferential statistical analysis using analysis of variance (ANOVA).

Results: The patients' mean age was 55.9 years, with a predominance of males (79.41%). Statistical differences were observed between the DHI emotional and total scores and alcohol consumption, and between the MLHFQ emotional scores and balanced diet. Regular physical activity differed statistically from the DHI and MLHFQ emotional impact and the total MLHFQ scores.

Conclusion: Harmful lifestyle habits such as alcohol consumption, poor diet, and a sedentary lifestyle negatively impacted the quality of life and self-perception of cardiological and vestibular symptoms in patients with heart failure and dizziness.

Purpose: To identify whether there are differences in the amplitude and width of spread of excitation (SOE) across the apical, medial and basal regions of the cochlea.

Methods: Cross-sectional retrospective study approved by the Ethics Committee of the institution. The study included adults with postlingual deafness, undergoing cochlear implant (CI) surgery, with present intraoperative neural responses in which the SOE was investigated in the basal (6), medial (11) and apical (16) electrodes. Neural response telemetry thresholds, peak amplitudes (µv) of the SOE function and SOE width in millimeters were collected and grouped by the electrode array type for analysis using the Mann Whitney and Kruskal Wallis tests.

Results: Seventy-one subjects were selected, 27 with perimodiolar array and 44 with straight array. There were no significant differences in the peak amplitudes among evaluated electrodes in both groups. However, SOE width (mm) of the medial electrode was significantly wider in both arrays, followed by the width of the basal electrode.

Conclusion: Although the SOE amplitude was similar suggesting similar neural recruitment in different regions of the cochlea, wider spread was found in the medial region even in the perimodiolar array. Thus, the use of objective tests will become increasingly important to assist in CI mapping, aiming for more effective and individualized programming.

Purpose: To investigate the online search behavior of the Brazilian population for information related to hearing loss, tinnitus, and dizziness.

Methods: This ecological and infodemiological study analyzed online search behavior in Brazil for the terms "Hearing Loss," "Dizziness," and "Tinnitus" from January 2014 to May 2024, using data from Google Trends™. Normalized relative search volumes (VPR) were calculated, and correlations between the terms were analyzed using Spearman's test, trend analysis with the Mann-Kendall test, and structural breaks with a significance level of 5%.

Results: Significant correlations were found between the terms "Dizziness" and "Hearing Loss," "Tinnitus" and "Hearing Loss," and "Tinnitus" and "Dizziness." An increasing trend in VPR was observed for "Hearing Loss," "Dizziness," and "Tinnitus." Structural breaks for each search term occurred in the following periods: Hearing Loss (two breaks): February 2016 and January 2021; Dizziness (five breaks): July 2015, July 2017, February 2019, April 2020, and December 2021; and Tinnitus (five breaks): April 2015, April 2017, March 2018, April 2020, and April 2022.

Conclusion: The search behavior over the past decade reveals a growing interest in information about hearing loss, tinnitus, and dizziness, with correlated results among the three terms. Sergipe had the highest search volume for "hearing loss," Maranhão for "dizziness," and São Paulo for "tinnitus."
