- Diabetes mellitus and sensorineural hearing loss: is there an association? Baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)(2017) SAMELLI, Alessandra G.; SANTOS, Itamar S.; MOREIRA, Renata R.; RABELO, Camila M.; ROLIM, Laurie P.; BENSENOR, Isabela J.; LOTUFO, Paulo A.OBJECTIVES: Although several studies have investigated the effects of diabetes on hearing loss, the relationship between these two conditions remains unclear. Some studies have suggested that diabetes may cause sensorineural hearing loss, whereas others have failed to find an association. The biggest challenge in investigating the association between diabetes and hearing loss is the presence of confounding variables and the complexity of the auditory system. Our study investigated the association between diabetes and sensorineural hearing loss. We evaluated the influence of time from diabetes diagnosis on this association after controlling for age, gender, and hypertension diagnosis and excluding those subjects with exposure to noise. METHODS: This cross-sectional study evaluated 901 adult and elderly Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) participants from Sao Paulo, Brazil who underwent audiometry testing as part of ELSA-Brasil's baseline assessment. RESULTS: Hearing thresholds and speech test results were significantly worse in the group with diabetes than in the group without diabetes. However, no significant differences were found between participants with and without diabetes after adjusting for age, gender, and the presence of hypertension. Hearing thresholds were not affected by occupational noise exposure in the groups with and without diabetes. In addition, no association between the duration of diabetes and hearing thresholds was observed after adjusting for age, gender, and hypertension. CONCLUSION: We found no association between the duration of diabetes and worse hearing thresholds after models were adjusted for age, gender, and the presence of hypertension.
- Analysis of possible factors of vocal interference during the teaching activity(2017) SILVA, Barbara Gabriela; CHAMMAS, Tiago Visacre; ZENARI, Marcia Simoes; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra Giannella; NEMR, KatiaOBJECTIVE: To measure the risk of dysphonia in teachers, as well as investigate whether the perceptual-auditory and acoustic aspects of the voice of teachers in situations of silence and noise, the signal-to-noise ratio, and the noise levels in the classroom are associated with the presence of dysphonia. METHODS: This is an observational cross-sectional research with 23 primary and secondary school teachers from a private school in the municipality of Sao Paulo, Brazil, divided into the groups without dysphonia and with dysphonia. We performed the following procedures: general Dysphonia Risk Screening Protocol (General-DRSP) and complementary to speaking voice teacher (Specific-DRSP), voice recording during class and in an individual situation in a silent room, and measurement of the signal-to-noise ratio and noise levels of classrooms. RESULTS: We have found differences between groups regarding physical activity (General-DRSP) and particularities of the profession (Specific-DRSP), as well as in all aspects of the perceptualauditory vocal analysis. We have found signs of voice wear in the group without dysphonia. Regarding the vocal resources in the situations of noise and silence, we have identified a difference for the production of abrupt vocal attack and the tendency of a more precise speech in the situation of noise. Both the signal-to-noise ratio and the room noise levels during class were high in both groups. CONCLUSIONS: Teachers in both groups are at high risk for developing dysphonia and have negative vocal signals to a greater or lesser extent. Signal-to-noise ratio was inadequate in most classrooms, considering the standards for both children with normal hearing and with hearing loss, as well as equivalent noise levels.
- Avaliação da atenção primária em saúde por usuários com e sem deficiência(2017) ALMEIDA, Maria Helena Morgani de; PACHECO, Samanta; KREBS, Stephanie; OLIVEIRA, Amanda Manso; SAMELLI, Alessandra; MOLINI-AVEJONAS, Daniela Regina; TOLDRÁ, Rosé Colom; OLIVER, Fátima CorrêaABSTRACT Purpose To evaluate the core (First Contact, Longitudinality, Comprehensiveness, and Coordination of Services) and derivative (Family Orientation, Community Orientation) attributes of primary health care (PHC) from the perspective of users with and without disabilities. Methods Observational, cross-sectional study using the Primary Care Assessment Tool (PCAT) with users with and without disabilities of five basic health units (BHU) in a municipality where 55% of the population depends on the Brazilian Unified Health System (SUS). Scores were assigned to the responses given to each of the PHC attributes evaluated. Results Study participants were 93 (67 physically disabled and 26 without disabilities) PHC users. No statistically significant differences were observed for any attribute on the comparison between the populations. For both groups, the attributes Degree of Affiliation, First Contact - Utilization, Longitudinality, and Coordination of Services - Information System received satisfactory (above cutoff) scores, whereas the attributes First Contact - Accessibility, Coordination of Services - Care Integration, Comprehensiveness, Family Orientation, and Community Orientation received unsatisfactory (below cutoff) scores. Users reported that the health teams are able to satisfactorily identify mobility issues, but there are failures in the recognition of problems of hearing, voice/speech and vision, and in the orientation of services available and services provided. Conclusion Users with and without disabilities evaluated the health care received similarly, indicating fragilities on the recognition of specific demands. Structural and work process changes should be conducted to ensure Accessibility, Comprehensiveness, and Family and Community Orientation, and thus increase the quality of PHC.
- Association between language and hearing disorders - risk identification(2017) SAMELLI, Alessandra Giannella; RONDON-MELO, Silmara; RABELO, Camila Maia; MOLINI-AVEJONAS, Daniela ReginaOBJECTIVE: To identify children at risk for hearing and/or language disorders and to investigate the association between these risks by conducting pre-validated hearing and language screenings. METHODS: The study was conducted during a polio vaccination campaign in August of 2013 in basic health units in western Sao Paulo. Parents of children between 2 and 5 years of age were asked to complete two screening tools: a hearing questionnaire (regarding hearing development) and a language production and comprehension scale (including the major language development milestones). The screening tools were administered by different researchers. We compared the risk of having language disorders among children at risk for hearing loss versus children not at risk, as well as the attributable risk and odds ratios. Chi-squared tests and logistic regression analyses were used. RESULTS: The study included 479 children with a mean age of three and one-half years, of whom 26.9% were identified as at risk for deficits in language production, 8.6% were at risk for deficits in language comprehension and 14% were at risk for hearing disorders. The children at risk for hearing disorders were twice as likely as those not at risk to exhibit language production and comprehension deficits. CONCLUSION: The results of this study highlight the importance of establishing and adopting low-cost procedures such as screenings to identify children at risk of developing language and/or hearing disorders in early childhood.
- Tablet-Based Hearing Screening(2017) SAMELLI, Alessandra G.; RABELO, Camila M.; SANCHES, Seisse G. G.; AQUINO, Camila P.; GONZAGA, DeniseIntroduction: Hearing loss (HL) affects people worldwide, many of whom are children. Especially in developing countries, epidemiological data on the prevalence of HL are insufficient to implement effective health promotion programs. In this preliminary study with young adults, we describe and validate a tablet-based hearing screening test developed for interactive remote hearing screening and compare the performance of an audiometry screening tablet application with conventional audiometry. In addition, the sensitivity, specificity, and predictive values of the tablet-based method and the concordance between the two methods were analyzed. Methods: Thirty volunteers participated in a double-blind study assessing two auditory threshold screening methods: tablet-based hearing screening and sweep audiometry. For both methods, a correct response to a minimum of two tones out of three emitted at 20 dBHL for the frequencies of 1, 2, and 4 kHz and 30 dBHL for 0.5 kHz in both ears, was considered a negative screening result (normal hearing), whereas hearing impairment was considered a positive screening result. Results: According to both methods, 26 participants had normal hearing and four had HL. The Kappa coefficient indicated perfect concordance between methods. The tablet-based hearing screening method had a sensitivity of 100% (confidence interval [CI]: 30.5-100.0), a specificity of 100% (CI: 87.1-100.0), a positive predictive value of 100% (CI: 30.5-100.0), and a negative predictive value of 100% (CI: 87.1-100.0). Conclusions: The tablet-based hearing screening test was shown to be a reliable and an accurate method for hearing screening that can be used effectively in places with Internet access and where local audiologists are not available.
