RESUMO
OBJECTIVES: To conduct critical assessment of the literature on the effects of cochlear implantation on adults' cognitive abilities. DESIGN: PubMed, Scopus, Lilacs, Web of Science, Livivo, Cochrane, Embase, PsycInfo, and grey literature were searched. Eligibility criteria: age 18 or over with severe-to-profound bilateral hearing loss, cochlear implantation, cognitive test before and after implantation. Risk of bias was assessed using ROB, ROBINS-I and MASTARI tools. Meta-analysis was performed. STUDY SAMPLE: Out of 1830 studies, 16 met the inclusion criteria. RESULTS: On AlaCog test, significant improvement was found after implantation [MD = -46.64; CI95% = -69.96 to -23.33; I2 = 71%]. No significant differences were found on the Flanker, Recall, Trail A and n-back tests (p > 0.05). For MMSE, no significance was found [MD 0.63; CI 95% = -2.19 to 3.45; I2 = 88%]. On TMT, an overall significant effect with a 9-second decrease in processing speed post-implantation [MD = -9.43; CI95% = -15.42 to -3.44; I2 = 0%]. CONCLUSION: Cognitive improvements after cochlear implantation may depend on time and the cognitive task evaluated. Well-designed studies with longer follow-up are necessary to examine whether cochlear implantation has a positive influence on cognitive abilities. Development of cognitive assessment tools to hearing-impaired individuals is needed.

BACKGROUND: Hearing problems can have adverse effects on an individual's job performance, as well as on unemployment or underemployment and increased risk of stress-related sick leave. OBJECTIVE: To investigate hearing impairment among workers and satisfaction with the use of hearing aids. METHODS: Cross-sectional study with workers who are hearing aid users. Subjects underwent pure tone audiometry and answered the Hearing Handicap Inventory for Adults and the Satisfaction with Amplification in Daily Life questionnaires. RESULTS: Participants were 36 workers between 36 and 75 years old, with an average age of 53.47 years, 52.7% male and 47.3% female. There was a mild to moderate hearing handicap perception, with worse results for women in the emotional domain. As hearing loss increased, workers' frustration increased when talking to coworkers. Everyone was satisfied with the use of their hearing aids. Satisfaction increased with increasing age and decreased with increasing hearing loss. The greater the frustration when talking to co-workers, the lower the overall satisfaction with hearing aid use; the lower the satisfaction with the competence of the professional who assisted in adapting the hearing aid; the lower the satisfaction in environments with background noise and overall worse personal image. The worse the attitudes and emotional responses of workers regarding their hearing impairment, the lower the overall satisfaction with the hearing aid. CONCLUSIONS: Despite the use of hearing aids, workers perceive having a hearing impairment, especially women. As hearing loss and frustration in talking with co-workers increased, satisfaction decreased.

This study aimed to assess the central auditory functions of endemic disease control agents. This cross-sectional cohort study comprised two groups: the exposed group, with 38 male endemic disease control agents with simultaneous occupational noise and pesticide exposure; and the control group, with 18 age- and sex-matched workers without occupational noise and/or pesticide exposure. All participants underwent pure-tone audiometry, brainstem auditory evoked potentials, dichotic digits test, and transient-evoked otoacoustic emissions suppression effect. There was a significant inter-group difference in waves III and V absolute latencies, and interpeak I-III and I-V latencies bilaterally, with worse results found in the exposed group. Abnormal dichotic digits test results occurred more often in the exposed group, with a significant association between pesticide- and noise-exposure and the abnormal results (p = 0.0099). The transient-evoked otoacoustic emissions with suppression effect did not yield significant inter-group differences. It was concluded that pesticide and noise exposure induce harmful effects on the central auditory functions, particularly on the brainstem and figure-ground speech-sound auditory skills.

In order to limit the spread of the coronavirus, several protective measures have been put in place in the community, in private and public residences and in health care centers. Some measures have a negative impact on communication. They include physical distancing, the use of face masks and shields as well as the increased use of telephone and videoconferencing for distance communication. The effects of COVID-19 are particularly harsh on older adults. Consequently, older adults, especially those with hearing loss, are particularly at risk of experiencing communication breakdowns and increased social isolation. Health care professionals should learn about and be encouraged to use communication strategies to maintain good interactions with their patients. This article proposes practical suggestions to health professionals who interact with older adults, especially those who have difficulty understanding speech. The goal of this article is to inform on the prevalence of hearing loss, the hearing difficulties experienced by older adults, the manifestations of hearing problems, the effects of pandemic protection measures on communication and the strategies that can be used to optimize professional-patient communication during a pandemic.
RESUMO
BACKGROUND: Several health conditions among professional fishermen have been reported. Among the risks to the health of fishermen, it should be noted that high noise levels cause hearing loss and general health problems. OBJECTIVE: to investigate the effects of exposure to occupational noise on hearing in professional fishermen at the main large-scale commercial fishing center in Brazil. METHODS: A cross-sectional study, 466 Brazilian commercial fishermen participated in the study, all males, ages range 18-67 years. A total of 15 vessels were included in the study. The first phase involved assessment of the sound pressure levels (SPLs) in the vessels, the second phase involved the use of a questionnaire and audiological assessment. RESULTS: Most compartments registered SPLs greater than 80 dBA and the noisiest compartment was the engine-room, where the vessel pilot works. Among the fishermen, tinnitus was the most commonly reported symptom (48.63%). A higher prevalence of hearing loss was observed in engine-room keepers. Longer the length of time in service, and consequently, exposure to noise (in years), were associated with higher auditory thresholds. CONCLUSION: the tolerance limits to noise exposure were exceeded according to legislation. Fishing activities are associated with noise-induced hearing loss, with the risk increasing with the length of service.

OBJECTIVE: To analyze and correlate the audiometric findings of high frequencies (9-16 kHz) in adolescents with their hearing habits and attitudes, in order to prevent noise-induced hearing loss. METHOD: This was a descriptive cross-sectional study, which included 125 adolescents in a sample of normal-hearing students, at a state school. The subjects performed high-frequency audiometry testing and answered a self-administered questionnaire addressing information on sound habits concerning the use of personal stereo devices. The sample was divided according to the exposure characteristics (time, duration, intensity, etc.) and the results were compared with the observed thresholds, through the difference in proportions test, chi-squared, Student's t-test, and ANOVA, all at a significance level of 0.05. RESULTS: Average high-frequency thresholds were registered below 15 dB HL and no significant correlation was found between high frequency audiometric findings and the degree of exposure. CONCLUSION: The prevalence of harmful sound habits due to the use of personal stereo devices is high in the adolescent population, but there was no correlation between exposure to high sound pressure levels through personal stereos and the high-frequency thresholds in this population.

Introduction Fishing, one of the oldest productive activities, is an important sector of the national and world economy. Aim To evaluate the vestibular behavior in a population of fishermen. Methods In a retrospective and cross-sectional study, 13 fishermen (mean 45.0), between 33 and 62 years of age, were submitted to anamnesis, otorhinolaryngological evaluation, and vestibular exam through the vector electronystagmography. Results The most evident otoneurologic symptoms were hearing loss (76.9%), tinnitus (61.7%), dizziness (46.1%), and headache (46.1%). The most evident clinical symptoms were fatigue (46.1%), depression (23.0%), anxiety (15.3%), insomnia (7.7%), and agitation during sleep (7.7%). There were alterations in the vestibular exam in 5 fishermen (38.5%) discovered in the caloric test. There was a prevalence of alteration in the peripheral vestibular system. There was a major frequency of the peripheral vestibular irritative syndrome. Conclusion The otoneurologic complaints were frequent in the population studied to verify the importance of allowing labyrinth exams and the need for adopting preventive measures relating to noise exposure as well as carbon monoxide exposure, because they can cause and/or enhance various manifestations of labyrinthine vestibular impairment that can affect the quality of life of these workers.
