Portuguese to English: Potencial evocado auditivo cortical em neonatos a termo e pré-termo: gênero e indicadores de risco para deficiência auditiva General field: Science Detailed field: Other
Source text - Portuguese Objetivo: Pesquisar os potenciais exógenos em neonatos normo-ouvintes, nascidos a termo e pré-termo, correlacionando-os ao gênero e presença de Indicadores de Risco para Deficiência Auditiva (IRDA). Métodos: A amostra inicial foi composta por 127 neonatos e, após análise de juízes, foram considerados 96. Destes, 66 eram nascidos a termo e 30 nascidos pré-termo, em um hospital público. Todos os neonatos apresentaram resultado “passa” na triagem auditiva neonatal. Os registros do exame foram feitos com os neonatos em sono natural, por meio de eletrodos assim posicionados: o ativo na fronte (Fz), o terra (Fpz) na fronte e os de referência na mastoide esquerda (M1) e direita (M2). Foram apresentados estímulos verbais, binauralmente, sendo /ba/ o estímulo frequente e /ga/ o estímulo raro, em intensidade de 70 dBNA, por meio de fones de inserção. Respeitou-se o paradigma oddball. Foi analisada a presença ou ausência dos potenciais exógenos. Para análise dos dados foram utilizados os testes estatísticos. Resultados: Houve diferença significativa nos valores dos componentes para o gênero feminino, relacionados à amplitude de N1-P2, na orelha esquerda. Não houve diferença entre presença de IRDAs e ausência de componentes. Conclusão: Verificou-se que os Potenciais Evocados Auditivos Corticais em neonatos apresentaram valores maiores de amplitude no Grupo Pré-termo, no gênero feminino, e ausência de diferença quanto à latência. Quanto à presença de IRDAs e ausência de componentes, não foi encontrada relação.
Translation - English Purpose: To investigate the exogenous potential in normal hearing neonates born at term and preterm, correlating them to gender and to the presence of risk indicators for hearing loss (IRDA). Methods: Of 127 newborns, 96 were considered after judges’ analysis. Sixty six were born at term and 30 preterm in a public hospital. All neonates had result "pass" in neonatal hearing screening. The exam records were made with newborns, in natural sleep, through positioned electrodes: the active on the forehead (Fz), the ground (Fpz) on the forehead and the reference ones on the left (M1) and right (M2) mastoid. Verbal stimuli were presented binaurally. The frequent stimulus was /ba/ and /ga/ was the rare stimulus, in intensity of 70 dBHL, through insert earphones. The oddball paradigm was respected. The presence or absence of exogenous potential was analyzed. For data analysis, statistical tests were used. Results: There was a statistically significant difference in the values of female gender components related to N1-P2 amplitude in the left ear. There was no significant difference between the IRDAs presence and components absence. Conclusion: It was verified that the cortical auditory evoked potentials in neonates present higher amplitude values in the preterm group in females, and no statistically significant difference related to latency. However, regarding the presence of IRDAs and absence of components, it was not found significant connection.

Bio
After a 5 years
experience in Dublin, Ireland, working in the catering industry and studying
Tourism Management, I am back in Brazil working as a tourist guide and travel
consultant for a tour operator. I also work part time as a freelancer
translator once English, as well as travelling, is one of my passions!
It is also
important to mention my job as an English teacher for 1 year, in a language
school in Brazil, and my volunteer experience translating articles for students
in the field of speech therapy, which have greatly increased my skills as a
translator.
My graduation as a journalist is also a strength,
since I have excellent skills also with my native language, Portuguese. I am a friendly and hard worker professional, with
meticulous attention to detail.
