Abstract
The effect of hypoxia on the functioning of the outer hair cells of the cochlea, which are responsible for the response to otoemissions used in neonatal hearing screening, is well known. The aim of this study is to determine the influence of mild to moderate variations in umbilical cord pH at birth on the outcome of hearing screening with otoemissions in healthy newborns without hearing risk factors. The sample is composed of 4536 healthy infants. The results show no significant differences in the hearing screening outcome between the asphyctic (<7.20) and normal pH group. Nor is a figure below 7.20 detected in the sample that is related to an alteration in the screening. When broken down into subgroups with known factors of variation in the screening result, such as gender or lactation, no significant differences in response were detected. Apgar ≤7 is significantly related to pH<7.20. In conclusion, mild-moderate asphyxia associated with delivery of healthy newborns, without auditory risk factors, does not alter the outcome of otoemission screening.

Abstract
OBJECTIVES The goal of this study is to determine if chronic obstructive pulmonary disease (COPD) is associated with sensorineural hearing loss (SNHL) in a national database. STUDY DESIGN Cross-sectional study. SETTING National sample of the United States population. PATIENTS Adults with audiometric and spirometry data from the National Health and Nutrition Examination Study (NHANES) database. INTERVENTIONS None. METHODS A total of 2,464 adults with spirometry and audiometry data from the NHANES database (2009-2012) were studied. Outcome measures included hearing, measured by high-frequency pure tone average (HFPTA; 3, 4, 6, 8 kHz) and low-frequency pure tone average (LFPTA; .5, 1, 2 kHz) frequencies. SNHL was defined as a HFPTA or LFPTA threshold more than 25 decibels (dB) in the better ear. Multivariable regression analyses explored the association between hearing loss and COPD. RESULTS The prevalence of COPD was 19.8% in individuals with SNHL in the better ear and 4.7% in individuals with normal hearing (p < 0.001). Presence of COPD was associated with elevated hearing thresholds (worse hearing) at each individual frequency. The presence of COPD was independently associated with a 3.29 dB (95% CI: 1.48, 5.09) increase in HFPTA (p < 0.001), and 2.32 dB (1.13, 3.50) increase in LFPTA (p < 0.001) after controlling for medical, social, and environmental covariates. The presence of COPD was independently associated with a 1.85-fold (1.12, 3.06) increased odds of isolated low-frequency SNHL (p = 0.017). CONCLUSIONS COPD was independently associated with sensorineural hearing loss after controlling for multiple confounding factors. These results contribute to the evidence that COPD and pulmonary dysfunction can be comorbid with hearing decline.

Abstract
Background/aim Ischemia is insufficient blood flow to provide adequate oxygenation. In the present study, we aimed to show whether acute hypoxia has a critical oxygen value that may lead to the deterioration of cochlear function. Materials and methods Under general anesthesia, prehypoxic signal-to-noise ratios were determined by distortion product otoacoustic emissions (DPOAE). The oxygen saturation (SaO2) values of rats were monitored with an oxygen saturation probe. Rats were injected with an extra dose of anesthetic agent, and SaO2 was reduced. DPOAE values in SaO2 100–90, 90–80, 80–70, and 70–60 posthypoxic values were measured and compared statistically with prehypoxic values. Results At 3000 and 4000 Hz, SaO2 70–60 values measured after the hypoxia were observed to be statistically significantly lower than the values measured before the hypoxia. At 6000 and 8000 Hz, SaO2 80–70 and 70–60 values measured after the hypoxia were observed to be statistically significantly lower than the values measured before the hypoxia. At 10,000 Hz, all of the values measured after the hypoxia were observed to be statistically significantly lower than the values obtained before the hypoxia. Conclusion Many studies have been conducted on the effects of hypoxia on the inner ear. It remains unclear how fluctuations in DPOAE levels affect hearing in clinical trials when the SaO2 starts to decrease. Although hypoxia has been implicated in the etiology of sudden hearing loss and tinnitus, the effects of acute hypoxia on the cochlea are still uncertain. Further studies are needed on this subject.

Abstract
OBJECTIVE The objective of this study was to establish the local incidence of hearing screening failure rate in newborns with all three stages of hypoxic ischemic encephalopathy (HIE). METHODS This retrospective cohort study was undertaken in a tertiary neonatal intensive care unit. Medical records and hearing secreening test results were collected for two years. RESULTS One hundred and ninety seven infants diagnosed with HIE, 20 of them died, 177 screened. Thirty five of 177 (19%) infants failed in screening test for hearing. Screening failure rate was 10/51 (19%), 20/105 (19%) and 5/21 (23%) in stage 1, 2 and 3, respectively and did not differ between HIE stages (p = 0.88). Furthermore failure rates were similar between infants who received therapeutic hypothermia or not (20% vs 19%, p = 0.84). CONCLUSION Hearing screening failure rate in HIE is quite high even in Stage 1 infants. Management and treatment of these infants should be made carefully concerning additional risks for hearing loss and long term follow-up even in Stage 1 HIE infants should be planned strictly.

Abstract
Background/aim This study was conducted to determine the critical partial oxygen pressure (pO2) value that would impair hearing function by evaluating the effects of hypoxia on hearing function in subjects diagnosed with chronic obstructive pulmonary disease (CPOD). Materials and methods The study included 25 male and 5 female patients referred to our clinic who were diagnosed with COPD, according to spirometry and PaO2 values, and who did not show pathology upon autoscopic examination. The control group consisted of 14 female and 16 male patients who had no lung disease and were in the same age range as the COPD group. Results A statistically significant difference was found between the two groups for distortion-product otoacoustic emission (DPOAE) (P < 0.001). The COPD group was divided into two groups according to pO2 levels (pO2 ≤ 70 and pO2 > 70) in order to find a critical pO2 level which might cause significant change at a certain audiological extent. Conclusion Hypoxia causes long-term decline in hearing thresholds, deterioration of DPOAE results, and prolongation of I–V interpeak latency in auditory brainstem response. However, the critical oxygen level that disrupts hearing function could not be determined.

Abstract
OBJECTIVE Acute mountain sickness (AMS) is caused by a low partial pressure of oxygen and may occur above 2500m. The aim of this research was to evaluate olfactory and gustatory abilities of healthy subjects during baseline conditions and after seven hours of normobaric hypoxia. METHODS Sixteen healthy subjects were assessed using the Sniffin' Sticks, as well as intensity and pleasantness ratings. Gustatory function was evaluated utilizing the Taste Strips. Experiments were carried out under baseline conditions (518m altitude) followed by a second testing session after seven hours of normobaric hypoxia exposure (comparable to 4000m altitude). RESULTS During normobaric hypoxia olfactory sensitivity and intensity estimates were significantly reduced. CONCLUSIONS We conclude that normobaric hypoxia leads to a significant decrease of olfactory sensitivity and intensity ratings.

Abstract
RESUMO Introdução Atualmente, somente a hipóxia neonatal grave (evidenciada pelo valor do Apgar) é considerada risco para a deficiência auditiva. A hipóxia é uma das causas mais comuns de lesão e morte celular. Nos casos de hipóxia leve ou moderada, embora menor, a privação da oxigenação está presente e, dessa forma, algum dano ao sistema auditivo pode ocorrer. Objetivo Investigar as amplitudes das emissões otoacústicas em recém-nascidos a termo sem risco para deficiência auditiva que apresentaram hipóxia leve ou moderada. Métodos Foram selecionados 37 recém-nascidos de ambos os sexos, divididos em dois grupos: 25 do grupo controle, formado por recém-nascidos sem hipóxia, e 12 do grupo estudo, formado por recém-nascidos com hipóxia leve ou moderada. Resultados Foram pesquisadas as EOAT e EOAPD em ambos os grupos e comparados os seus resultados. Nas EOAPD foram encontradas diferenças estatísticas entre as amplitudes nas frequências 1.000, 2.800, 4.000 e 6.000 Hz. Nas EOAT foram encontradas diferenças estatísticas nas bandas de frequência de 1.000, 1.400, 2.000, 2.800 e 4.000 Hz, sendo as EOA do grupo estudo menores que as do grupo controle. Conclusão Embora a ocorrência de hipóxia neonatal leve e moderada não seja considerada risco para perda auditiva, a mínima privação do oxigênio durante o momento de hipóxia neonatal parece interferir no funcionamento das células ciliadas externas e, consequentemente, no nível de respostas das emissões otoacústicas. Dessa forma, faz-se necessário o acompanhamento longitudinal desses lactentes, a fim de identificar o possível impacto desses resultados na aquisição de linguagem e, futuramente, no desempenho escolar.
