Abstract
IMPORTANCE Early detection and intervention of hearing loss may mitigate negative effects on children's development. Children who were admitted to the neonatal intensive care unit (NICU) as babies are particularly susceptible to hearing loss and risk factors are vital for surveillance. DESIGN, SETTING AND PARTICIPANTS This single-centre retrospective cohort study included data from 142 inborn infants who had been admitted to the NICU in a tertiary regional referral centre. Data were recorded for 71 infants with confirmed permanent congenital hearing loss hearing loss. To determine impact of NICU admission independently of prematurity, babies were individually matched with 71 inborn infants on gestational age, birthweight, and sex. MAIN OUTCOMES AND MEASURES Neonatal indicators were recorded for all children with permanent congenital hearing loss. Presence of UK and US risk factors for hearing loss were collected on the neonatal population with hearing loss and for the matched controls. RESULTS A fifth (21%) of babies with hearing loss had one or more UK risk factors whereas most (86%) had at least one US risk factor. False positives would be evident if US factors were used whereas the matched controls had no UK risk factors. Ten babies who at birth had no UK or US risk factors did not have any significant neonatal indicators identified in their records, one was ventilated for one day and two had a genetic anomaly. CONCLUSIONS AND RELEVANCE Current risk factors for hearing loss we identified for follow-up in this high-risk group are highly specific for congenital hearing loss. UK risk factors were highly specific for hearing loss but not sensitive and conversely, US risk factors are sensitive but not specific so false positives would be recorded. A national study of neonatal indicators could provide the utility to test which combinations of risk factors provide high sensitivity without losing specificity.

Abstract
Children with cerebral palsy (CP) face communication challenges stemming from neural lesions, hearing issues, and executive function impairments, which are further complicated by interactions between motor and hearing impairments. These challenges lead to limitations in daily activities and are compounded by delays in diagnosis and interventions, adversely affecting speech, language, and cognitive function. In infants with CP, impaired motor function disrupts both feedforward and feedback mechanisms crucial for speech sound production, exacerbating the overall impact on communication development. Understanding the interplay between hearing loss and speech production in children with CP, especially in the crucial early developmental stages, is essential for implementing timely interventions and guiding multidisciplinary care teams in both clinical and home settings. IMPACT QUESTIONS: Children with cerebral palsy (CP) face communication challenges due to neural, hearing, and motor issues, impacting speech and language development. Early and comprehensive testing, including auditory brainstem response, is crucial for timely diagnosis and intervention to mitigate adverse effects. The article emphasizes the need for advanced diagnostics and multidisciplinary interventions to improve communication skills and cognitive outcomes in children with CP.

Abstract
OBJECTIVE To investigate the risk for sensorineural hearing impairment (SNHI) in preterm infants, and to what extent the risk is attributed to perinatal morbidities and therapies. DESIGN Population-based cohort study using data from several nationwide registries. SETTING Norwegian birth cohort 1999-2014, with data on SNHI until 2019. PARTICIPANTS 60 023 live-born preterm infants, divided in moderate-late preterm (MLP) infants (32-36 weeks), very preterm (VP) infants (28-31 weeks) and extremely preterm (EP) infants (22-27 weeks), and a reference group with all 869 797 term-born infants from the study period. MAIN OUTCOME MEASURES SNHI defined by selected ICD-10 codes, recorded during minimum 5-year observation period after birth. RESULTS The overall SNHI prevalence in the preterm cohort was 1.4% compared with 0.7% in the reference group. The adjusted risk ratios (95% CIs) for SNHI were 1.7 (1.5-1.8) in MLP infants, 3.3 (2.8-3.9) in VP infants and 7.6 (6.3-9.1) in EP infants. Among EP infants, decreasing gestational age was associated with a steep increase in the risk ratio of SNHI reaching 14.8 (7.7-28.7) if born at 22-23 weeks gestation. Among the VP and MLP infants, mechanical ventilation and antibiotic therapy had strongest association with increased risk of SNHI, but infants not receiving these therapies remained at increased risk. Among EP infants intracranial haemorrhage increased the already high risk for SNHI. We found no signs of delayed or late-onset SNHI in preterm infants. CONCLUSION Preterm birth is an independent risk factor for SNHI. Invasive therapies and comorbidities increase the risk, predominantly in infants born after 28 weeks gestation.

Abstract
OBJECTIVE To identify sociodemographic factors associated with pediatric late-identified hearing loss (LIHL) and classify novel subgroups within the LIHL population. STUDY DESIGN Retrospective cohort. SETTING Tertiary children's hospital. METHODS Our cohort included children with permanent hearing loss (HL) between 2012 and 2020 (n = 1087). Patients with early-identified HL were compared to patients with LIHL (>6 months of age at diagnosis), and 3 subgroups: (1) late-identified congenital HL: failed NHS but had a diagnostic audiogram >6 months old; (2) late-onset HL: passed NHS and identified with HL after 6 months old; (3) late-identified, unknown-onset: unknown NHS results, identified after 6 months old. Geospatial analysis was performed using ArcGIS Pro. RESULTS Compared with early-identified children, children with LIHL were more likely to have more comorbidities (odds ratio [OR] = 1.12, [1.01, 1.23]), be an under-represented minority (URM) (OR = 1.92, [1.27, 2.93]) and have a higher social vulnerability index (SVI) (adjusted odds ratio [AOR] = 2.1, [1.14, 3.87]). However, subgroups in the LIHL cohort had variable associations. Children with late-identified unknown onset hearing loss were uniquely associated with a primarily non-English speaking household (AOR = 1.84, [1.04, 3.25]), whereas children with late-onset hearing loss were less likely to have public insurance (AOR = 0.47, [0.27, 0.81]. There were no significant associations for children with late-identified congenital hearing loss. Neighborhood disadvantage, as measured by SVI, had an increased association with late-identified unknown onset HL (AOR = 4.08, [2.01, 8.28]) and a decreased association with late-onset HL (AOR = 0.40, [0.22, 0.72]). CONCLUSION Sociodemographic factors serve as proxies for health care access, and these factors vary across LIHL pathways. Understanding the risk factors associated with each LIHL subgroup may help address disparities in pediatric HL identification.

Abstract
PURPOSE This study discusses the history and current state of the newborn hearing screening program in Québec and aims to assess general challenges associated with establishing universal newborn hearing screening (UNHS) programs. METHOD We reviewed the statistics of the occurrence and long-term effects of congenital hearing loss and the immediate and long-term benefits of UNHS and its limitations. The resources for this study included financial reports related to establishing UNHS in different health care systems; Canadian provincial, territorial, and federal regulations and publications; local and nationwide media; and interviews health care staff and program managers. RESULTS Because of its benefits and its cost-effectiveness, UNHS programs have been implemented in many health care systems around the world. Despite Canada's success in offering a wide array of health care services to its citizens, certain provinces trail behind others in developing UNHS programs. Although there have been recent improvements in the screening rate of the province of Québec, nearly half of all Québec newborns continue to not be screened for hearing loss. The reasons for the current low screening rate include delays in implementation, information-technology complications, operating costs, and lack of public awareness. CONCLUSIONS For UNHS to be implemented in a timely fashion, those involved in the process should first understand what challenges may arise. Québec's experience with this process may provide useful lessons for other health care systems.

Abstract
OBJECTIVE Infants diagnosed with a conductive hearing loss (CHL) are at increased risk of developmental delays. Using a sample of infants diagnosed with CHL through UNHS, this study aimed to investigate the relationship between specific demographic or clinical characteristics and 1) occasions of service to reach a hearing diagnosis and 2) the profile of CHL. METHODS Retrospective analysis was conducted for all infants with CHL born between 01/01/2007 and 31/12/2018 who had received UNHS. Chi squared analysis was conducted on data from 1208 records. RESULTS Infants with ≥1 risk factor for hearing loss were more likely to attend more than three occasions of service. Infants who were bilateral refer/medical exclusion, Torres Strait Islander, had ≥1 risk factors for hearing loss or were born pre-term had greater proportions of bilateral CHL than unilateral CHL. Mild to moderate was the most frequent degree of CHL, although a unilateral or bilateral CHL did not have an association with the severity of CHL. Compared to other risk factors, infants with a syndrome had greater proportions of bilateral than unilateral CHL. Risk factors of craniofacial abnormality, prolonged ventilation, or syndrome had greater proportions of mild to moderate CHL than moderate or greater. On average, infants were diagnosed with a CHL at 37.29 weeks of age. CONCLUSION These findings highlight the relationship between clinical/demographic characteristics and occasions of service to diagnose CHL in children, including the CHL profile. An understanding of this relationship may help clinicians to better plan, assess and manage infants diagnosed with a CHL through UNHS.

Abstract
Hearing loss is considered the most common birth defect. The estimated prevalence of moderate and severe hearing loss in a normal newborn is 0.1%-0.3%, while the prevalence is 2%-4% in newborns admitted to the newborn intensive care unit. Neonatal hearing loss can be congenital (syndromic or non-syndromic) or acquired such as ototoxicity. In addition, the types of hearing loss can be conductive, sensorineural, or mixed. Hearing is vital for the acquisition of language and learning. Therefore, early detection and prompt treatment are of utmost importance in preventing the unwanted sequel of hearing loss. The hearing screening program is mandatory in many nations, especially for high-risk newborns. An automated auditory brainstem response test is used as a screening tool in newborns admitted to the newborn intensive care unit. Moreover, genetic testing and screening for cytomegalovirus in newborns are essential in identifying the cause of hearing loss, particularly, mild and delayed onset types of hearing loss. We aimed to update the knowledge on the various aspects of hearing loss in newborns with regard to the epidemiology, risk factors, causes, screening program, investigations, and different modalities of treatment.

Abstract
The purpose of the present systematic review was to synthesize evidence on associated risk factors of hearing loss (HL) in children. Evidence-based research articles on HL published between January 2013 and December 2022 using PubMed, Cochrane, and Scopus databases were searched. The study included children between zero and three years of age who have permanent bilateral/unilateral HL (BHL/UHL) by employing case-control studies, randomized controlled trials, nonrandomized studies, prospective or retrospective cohort studies, and studies with or without comparison groups. The Newcastle-Ottawa Scale (NOS) and the Joanna Briggs Institute (JBI) critical appraisal checklist for longitudinal and cross-sectional studies were used to rate the quality of the chosen studies. The studies that would be considered were reviewed by two independent authors, and a third author was contacted if there was a dispute. A preliminary literature search uncovered 505 articles from the electronic search and 41 studies by hand searching. Duplicate records were eliminated, leaving 432 records. The abstract and title were read, and 340 studies were eliminated. There were 92 articles in total that qualified for full-text screening. Among these, 75 articles were disregarded since they lacked information or failed to assess the risk factors for HL. The qualitative synthesis, therefore, included 17 articles. Most often, cross-sectional study designs were used in the studies that were reviewed, which were then followed by longitudinal studies. Three of the studies that were reviewed used a prospective cohort design. The quality of all the included studies was rated to be good. The current review revealed that the primary statistically significant risk factors for HL included ventilator support; craniofacial anomalies; low birth weight (LBW); forceps delivery; loop diuretics; meningitis; asphyxia; intensive care; consanguinity; sepsis; Apgar scores between 0 and 4 at one minute; toxoplasmosis, other agents, rubella, cytomegalovirus, and herpes (TORCH) infections; and hyperbilirubinemia.

Abstract
Newborn hearing screening (NHS) was implemented in Albania in four maternity hospitals in 2018 and 2019. Implementation outcome, screening outcome, and screening quality measures were evaluated. Infants were first screened by midwives and nurses before discharge from the maternity hospital and returned for follow-up screening. Acceptability, appropriateness, feasibility, adoption, fidelity, coverage, attendance, and stepwise and final-referral rates were assessed by onsite observations, interviews, questionnaires, and a screening database. A post hoc analysis was performed to identify reasons for loss to follow up (LTFU) in a multivariate logistic regression. In total, 22,818 infants were born, of which 96.6% were screened. For the second screening step, 33.6% of infants were LTFU, 40.4% for the third, and 35.8% for diagnostic assessment. Twenty-two (0.1%) were diagnosed with hearing loss of ≥40 dB, six unilateral. NHS was appropriate and feasible: most infants are born in maternity hospitals, hence nurses and midwives could perform screening, and screening rooms and logistic support were supplied. Adoption among screeners was good. Referral rates decreased steadily, reflecting increasing skill. Occasionally, screening was repeated during a screening step, contrary to the protocol. NHS in Albania was implemented successfully, though LTFU was high. It is important to have effective data tracking and supervision throughout the screening.

Abstract
INTRODUCTION National recommendations in the United States specify that all infants with hearing impairment should be identified by 3 months of age. Infants who fail universal newborn hearing screening (UNHS) require follow up testing after hospital discharge. Follow up testing may be difficult to obtain in some communities within the ideal time frame. A rapid access multidisciplinary clinic was established for failed UNHS. The objective of this study is to report outcomes and patient satisfaction from an early access hearing detection clinic. METHODS Infants that failed UNHS were seen in the multidisciplinary clinic between 1/1/19 and 2/28/22. Patients underwent automated auditory brainstem response (ABR) and distortion product otoacoustic emissions testing and consulted with an otolaryngology nurse practitioner. Failed results were followed by diagnostic ABR. Surveys were administered at the beginning and end of the appointment. RESULTS In total, 169 infants were seen at a mean age of 8.4 weeks (95%CI 7.5, 9.4). Repeat testing was abnormal in 38 (22.4%). Diagnostic ABR was performed at an average age of 13.7 weeks (n = 34, 95% CI: 10.8, 16.6) and led to a diagnosis of hearing loss in 18 infants. Twenty-seven parents completed surveys at the initial visit. Anxiety level among patients with normal repeat testing (n = 20) decreased from 1.9 to 1.2 (p = .002), while anxiety level among those with abnormal repeat testing (n = 7) was not statistically different before and after (2.1 vs 2.7, p = .2). Satisfaction level was 3.7 ± 0.7 (scored 1-4). All parents reported having a better understanding of their child's hearing problem after the visit. DISCUSSION This novel nurse practitioner-led early hearing detection clinic enabled timely diagnosis of hearing loss and reassurance to families without hearing loss. Age at hearing loss diagnosis compares favorably to published cohorts.

Abstract
BACKGROUND Universal Newborn Hearing Screening (UNHS) aims to identify infants born with a permanent hearing loss. However, many are also diagnosed with a conductive hearing loss (CHL) and are at subsequent risk for developmental delays. The aim of this study was to investigate the prevalence of CHL and determine which clinical characteristics collected at birth, predict CHL within UNHS. MATERIALS AND METHODS Retrospective analysis was conducted on all infants born between January 01, 2007 and December 31, 2018. During this period, 731,234 infants were screened, 9802 were direct referrals, and 1208 identified with a CHL. Chi squared analysis and logistic regression was conducted to determine CHL prevalence and identify which clinical characteristics predict CHL. RESULTS The prevalence of CHL was 12.32%. Following adjustments for collinearity, clinical characteristics that could predict CHL were: bilateral referrals/medical exclusions to screen (Odds ratio, OR 1.89; 95% CI: 1.65-2.1), ≥1 risk factor for hearing loss (OR 2.03; 95% CI: 1.76-2.34), pre-term birth (OR 1.82; 95% CI: 1.57-2.10), male (OR 1.21; 95% CI: 1.07-1.37), and Indigenous status: 'Aboriginal (not Torres Strait Islander)' (OR 1.27; 95% CI:1.03-1.57 and 'not stated' (OR 2.95; 95% CI: 2.02-4.30). CONCLUSION CHL within UNHS was highly prevalent, with six clinical characteristics that can predict that likelihood of an infant being diagnosed with a CHL. This data could be used to create alternative care pathways for infants with CHL, enabling early and targeted assessments, thereby reducing the risk of developmental delays for these infants.

Abstract
Background: Objectives of the present work were to analyze the prevalence of hearing loss in our population of screened newborns during the first 9 years of the universal newborn hearing screening (UNHS) program at University Hospital Sassari (Italy) (AOU Sassari), to analyze the risk factors involved, and to analyze our effectiveness in terms of referral rates and dropout rates. Methods: Monocentric retrospective study whose target population included all the newborns born or referred to our hospital between 2011 and 2019. Results: From 2011 to 2019, a total of 11,688 babies were enrolled in our screening program. In total, 3.9‱ of wellborn babies and 3.58% of neonatal intensive care unit (NICU) babies had some degree of hearing loss. The most frequently observed risk factors among non-NICU babies were family history of hearing loss (3.34%) and craniofacial anomalies (0.16%), among NICU babies were low birth weight (54.91%) and prematurity (24.33%). In the multivariate analysis, family history of hearing loss (p < 0.001), NICU (p < 0.001), craniofacial anomalies (p < 0.001), low birth weight (<1500 g) (p = 0.04) and HIV (p = 0.03) were confirmed as risk factors. Conclusions: Our data are largely consistent with the literature and most results were expected, one relevant exception being the possible role of NICU as a confounding factor and the limited number of risk factors confirmed in the multivariate analysis.

[PMID: 36032914 PMCID: PMC9411340 DOI: 10.1007/s12070-021-02435-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 02/02/2021] [Indexed: 11/30/2022] Open
Abstract
Objective The aim of this study is to estimate the incidence of hearing loss in neonates at a tertiary referral center, to assess the associated risk factors in those identified with hearing loss and to explore the challenges of starting and continuing a universal neonatal hearing screening programme in a tertiary care hospital over a decade. Materials and Methods It is a cohort prospective observational study conducted from January 2008 to January 2018. Five thousand five hundred and forty neonates underwent screening for hearing loss, of which 2688 were well babies and 2854 babies had one or more risk factors causing hearing loss. Otoacoustic emissions (OAE) is employed as the first level of screening within one month of birth. Brainstem evoked response audiometry (BERA) is done at 3 months of gestational age for all the well babies who were referred on OAE testing and all the high risk babies irrespective of the result of the OAE screening. The High risk criteria are based on the set criteria by the Joint Committee on Infant Hearing (2007) and American Academy of Pediatrics (1994). Results In our study the incidence of hearing impairment is 5.41 per 1000 neonates screened. In well babies and at risk babies it is 1.49 and 9.11 per 1000 respectively.The common neonatal risk factors associated with hearing loss in our study are babies admitted to neonatal intensive care units (NICU), intrauterine growth retardation (IUGR), birth weight less than 1500 g, respiratory distress syndrome (RDS) and hyperbilirubinemia. Conclusion The incidence of hearing loss in our study is comparable to that reported in literature (Bachmann KR, ArvedsonJC (1998) Early identification and intervention for children who are hearing impaired. Pediatr Rev. 1998 May; Vol. 19. No.5. pp. 155-165. http://www.ncbi.nlm.nih.gov/pubmed/9584525 Accessed from May 1998, Nagapoornima P, Ramesh A, Srilakshmi, Rao S, Patricia PL, Gore M, et al. Universal hearing screening. Indian J Pediatr. 2007 Jun 18; 74(6):545-9., Augustine AM, Jana AK, Kuruvilla KA, Danda S, Lepcha A, Ebenezer J, et al. (2014) Neonatal hearing screening-experience from a tertiary care hospital in southern India. Indian Pediatr. Vol. 51. No.3. pp 179-183. http://www.ncbi.nlm.nih.gov/pubmed/24277966 Accessed from Mar 2014). Hearing loss is more common in those babies with risk factors as reported in literature (Nagapoornima P, Ramesh A, Srilakshmi, Rao S, Patricia PL, Gore M, et al. Universal hearing screening. Indian J Pediatr. 2007 Jun 18; 74(6):545-9. http://www.ncbi.nlm.nih.gov/pubmed/21654001 Paul AK (2011) Early identification of hearing loss and centralized newborn hearing screening facility-the Cochin experience. Indian Pediatr. Vol. 48. No. 5. pp 355-359. Accessed from May 2011). Implementation of neonatal hearing screening program at a tertiary care hospital using a two tier system with OAE and BERA is a feasible but challenging service.

Abstract
Hearing is a special sense needed for appropriate mental, speech and language development and academic performance. Even among normal babies, 50% of cases of hearing loss are missed out if screening protocol is not followed. In this study, we assess the hearing of all neonates born and brought to the tertiary care hospital, and also find out how many well babies with hearing loss would have been missed if this screening had not been done. Hence, the study aims to estimate the prevalence of neonatal hearing loss and study the associated risk factors. Neonates (N = 1559) attended the outpatient department of paediatrics were included. A detailed history of the neonates with special emphasis on prenatal, natal, postnatal, family history, and maternal risk factors were elicited. Three-stage hearing testing protocol was followed with transient evoked otoacoustic emission testing, a gold standard test for stage 1 and 2 and brainstem evoked response audiometry for stage 3. Of 1559 neonates, 138 had hearing loss. History of drug intake, order of the child, place of delivery and maternal history were the significant factors associated with hearing loss in neonates. Bivariate analysis revealed order of child, maternal history, and history of drug taken were the significant factors affecting the hearing loss in the neonates (P < 0.001). The prevalence of hearing loss was 8.85%. Early detection of hearing loss is essential for timely intervention and development of optimal communication skills. Further studies are required to decide the essentiality of Universal New-born hearing screening.

Abstract
OBJECTIVES To reveal the risk situations of ROP patients in terms of hearing loss by examining the newborn hearing screening test results. METHODS Hearing screening test results of ROP patients and newborns with similar congenital risk factors(control group) treated in our hospital were retrospectively screened. Both groups were compared in terms of newborn hearing screening test results. RESULTS In the first screening test, the rate of ''refer'' result in the ROP group was significantly higher than the control group (p < 0.05). There was no significant difference between the two groups in terms of second hearing screening test results (p > 0.05). In the second screening test, 100% of stage 3 ROP patients failed from the right ear and 80% in the left ear, and this difference was statistically significant compared to the other two groups (p < 0.05). CONCLUSION Newborn hearing screenings of patients with advanced stage ROP patients should be followed up more sensitively, since stage 3 ROP patients had more failure results from the screening test in our study.

Abstract
AIM To compare listening and spoken language outcomes after cochlear implantation for children born preterm and at term, and to examine patterns associated with additional disabilities or gestational age. METHOD Children were included if they underwent cochlear implantation in 2013 or 2014 and had complete 5-year follow-up data available. An analysis of assessment data recorded annually was conducted, including outcomes as measured by the Category of Auditory Performance (CAP), the Speech Intelligibility Rating, Second Edition (SIR 2) scale, and the British Picture Vocabulary Scales, Third Edition (BPVS-3). Analyses were conducted to measure the impact of preterm birth and of additional causes of disability on these outcomes. RESULTS Eighty-two children (39 males, 43 females; median corrected age at first cochlear implantation 28.5mo [interquartile range 16.3-48.5]) were included in the study. Children who underwent cochlear implantation experienced significant improvements as measured by the CAP, SIR 2, and BPVS-3. Comparable improvements were seen in the groups born at term and preterm. Children with additional disabilities experienced significant improvement in all measures but performed less well than children without additional disabilities. INTERPRETATION Infants born preterm benefit from cochlear implantation to a degree comparable to their peers born at term. Additional disabilities may limit improvements in speech intelligibility, listening performance, and receptive vocabulary. Children with additional disabilities, nonetheless, derived significant benefit from cochlear implantation; additional benefits of cochlear implantation for this subgroup may go unmeasured by the outcome tools used in this study.

Abstract
AIM To synthesize published evidence regarding hearing impairment diagnosis and interventions in infants with or at high risk for cerebral palsy in the first year after birth. METHOD Nine databases were searched for MeSH terms up to February 2020. Included studies were published in English, enrolled infants with or at high risk for cerebral palsy, and addressed hearing evaluation/rehabilitation within the first year after birth. Quality of evidence was evaluated using RTI Item Bank and QUADAS-2. RESULTS Eighteen articles met inclusion criteria. Quality of the evidence ranged from low to high, revealing variability in diagnostic assessment methodologies and adherence to diagnostic schedules. Concerns for bias included lack of recognition of cerebral palsy effects and etiologies on functional hearing assessment methods and results. Two interventions (hearing aid and cochlear implantation) were identified; however, reported use was inconsistent. INTERPRETATION Hearing screening in infants with or at high risk for cerebral palsy requires evaluation of the entire auditory pathway preferentially using comprehensive electrophysiological panels of assessments. For infants with perinatal neural insults, pediatric neurologists are uniquely positioned to recommend adherence to systematic surveillance and comprehensive audiology assessments, regardless of comorbidities and motor impairments.

Abstract
INTRODUCTION Newborn hearing screening is essential for early identification of hearing loss to decrease the adverse effects of hearing loss. The objective of this study was to determine the prevalence of hearing loss and risk factors of congenital hearing loss in newborns. METHODS In this analytical case-control study, a hearing screening test was performed for all newborns aged 3-14 days. RESULTS Of 5,500 newborns evaluated, 24 newborns had hearing loss. The prevalence of hearing loss was 4.36 per 1,000. Of 24 hearing-impaired newborns, 15 had bilateral hearing loss (BHL) (62.5%) and nine had unilateral hearing loss (UHL) (37.5%). Among the neonates with hearing loss, the prevalence of hearing loss was higher (77.8%) in the right ear. The main risk factors identified in this study were low gestational age (P=0.001), hospitalization in the neonatal intensive care unit (NICU) (P=0.008), exposure to ototoxic drugs (P=0.001), gestational diabetes P=0.01), craniofacial anomalies (P=0.01), convulsion (P=0.03), consanguineous marriage of parents (P=0.001), low birth weight (P=0.01), and hyperbilirubinemia (P=0.001). CONCLUSION The prevalence of hearing loss was higher in the right ear than in the left ear. NICU stay, use of ototoxic drugs, low gestational age (<35 weeks), gestational diabetes, craniofacial anomalies, convulsion, consanguineous marriage of parents, low birth weight, and hyperbilirubinemia were significant risk factors for congenital hearing loss in studied newborns.

Abstract
Introduction Despite the high burden of hearing loss (HL) globaly, most countries in resource limited settings lack infant hearing screening programs(IHS) for early HL detection. We examined the feasibility of establishing an IHS program in this setting, and in this pilot program measured the prevalence of infant hearing loss (IHL) and described the characteristics of the infants with HL. Methods We assessed feasibility of establishing an IHS program at a regional referral hospital in south-western Uganda. We recruited infants aged 1 day to 3 months and performed a three-staged screening. At stage 1, we used Transient Evoked Oto-acoustic Emissions (TEOAEs), at stage 2 we repeated TEOAEs for infants who failed TEOAEs at stage 1 and at stage 3, we conducted Automated brainstem responses(ABRs) for those who failed stage 2. IHL was present if they failed an ABR at 35dBHL. Results We screened 401 infants, mean age was 7.2 days (SD = 7.1). 74.6% (299 of 401) passed stage 1, the rest (25.4% or 102 of 401) were referred for stage 2. Of those referred (n = 102), only 34.3% (35 of 102) returned for stage 2 screening. About 14.3% (5/35) failed the repeat TEOAEs in at least one ear. At stage 3, 80% (4 of 5) failed the ABR screening in at least one ear, while 25% (n = 1) failed the test bilaterally. Among the 334 infants that completed the staged screening, the prevalence of IHL was 4/334 or 12 per 1000. Risk factors to IHL were Newborn Special Care Unit (NSCU) admission, gentamycin or oxygen therapy and prematurity. Conclusions IHS program establishment in a resource limited setting is feasible. Preliminary data indicate a high prevalence of IHL. Targeted screening of infants at high risk may be a more realistic and sustainable initial step towards establishing IHS program s in a developing country like Uganda.

Abstract
OBJECTIVE To characterize the association between hyperbilirubinemia and a failed newborn hearing screen in infants born at 22-32 weeks of gestation. STUDY DESIGN We included infants with gestational ages of 22-32 weeks who were discharged from neonatal intensive care units in the US from 2002 to 2017 with available newborn hearing screen results obtained after 34 weeks postmenstrual age. We excluded infants with severe birth asphyxia or craniofacial abnormalities. We identified 95 672 infants from 313 neonatal intensive care units. We used multivariable logistic regression to examine the association between maximum total bilirubin at <21 days postnatal age with failed hearing screen, adjusting for important demographic and clinical risk factors. RESULTS The median gestational age and birth weight were 30 weeks (IQR, 28-32 weeks) and 1330 g (IQR, 1010-1630 g), respectively. The median maximum total bilirubin was 8.3 mg/dL (IQR, 6.7-10.0 mg/dL), and 5275 infants (6%) failed their newborn hearing screen. On adjusted analysis, each 1 mg/dL increase in maximum total bilirubin was associated with a small, but significant, increase in odds of a failed hearing screen (OR, 1.03; 95% CI, 1.02-1.04). CONCLUSIONS An increased maximum total bilirubin level was independently associated with hearing screen failure. Further prospective studies are needed to understand whether this increased risk of hearing screen failure translates to increased risk of hearing loss.

Abstract
OBJECTIVE This study investigated whether demographic variables, risk factor presence or absence and universal newborn hearing screening (UNHS) results can be used to predict permanent childhood hearing loss (PCHL) in infants referred from screening. DESIGN Retrospective analysis of a UNHS database. STUDY SAMPLE Data were extracted from the state-wide UNHS database storing details of the 613,027 infants who were born in Queensland, Australia between 1 January 2007 and 31 December 2016 and participated in UNHS. This study included the 6735 children who were referred from the UNHS program for diagnostic audiology due to failing the screen in one or both ears or bypassing screening. RESULTS Factors with a significant positive association with PCHL that were incorporated into a logistic regression model were: female gender, non-indigenous status, family history of PCHL, craniofacial anomalies and syndromes associated with PCHL, and a bilateral refer result on screening. CONCLUSIONS Odds of PCHL vary among infants referred for diagnostic assessment from UNHS programs. When an infant refers on the newborn hearing screen, information about their gender, indigenous status, identified risk factors and specific screening outcome can be used to predict the likelihood of a congenital PCHL diagnosis.

Abstract
OBJECTIVES To determine the incidence and risk factors of hearing loss (HL) in Brazilian neonates. STUDY DESIGN 11,900 neonates were screened for hearing and congenital CMV (cCMV). Low and high-risk babies who did not pass their hearing screening and infants with cCMV were scheduled for a diagnostic audiologic evaluation. RESULTS The incidence of HL was 2 per 1000 live-born infants (95% CI: 1-3). HL was higher in high-risk neonates than in low risk babies (18.6 vs. 0.3/1000 live births, respectively). Among infants exposed to isolated risk factors, association of HL with craniofacial abnormalities/syndromes (RR = 24.47; 95% CI: 5.9-100.9) and cCMV (RR = 9.54; 95% CI: 3.3-27.7) were observed. HL was 20 to 100-fold more likely in neonates exposed to ototoxic drugs in combination with cCMV or craniofacial/congenital anomalies. CONCLUSIONS Strategies for the prevention of cCMV and exposure to ototoxic drugs may decrease the incidence of HL in this population.

Abstract
We report a case of neuro-ophthalmological complications of congenital toxoplasmosis, a parasitic infection caused by Toxoplasma gondi. Its congenital form occurs either as a primary infection or as reactivation of the same due to immunosuppression during pregnancy. With an incidence rate of 1.5/1000 live births, this disease is an important cause of visual loss from chorio-retinal lesions in >82%. Recent studies have shown that treatment given in utero and in the first year of life can reduce ophthalmological complications.

Abstract
Background: Hearing is necessary for speech and language development, children with bilateral hearing loss often have impaired speech and language abilities thus limiting educational attainment. Early detection and intervention will help minimize such effects. Therefore, neonatal hearing screening program has been advocated in developing countries. Objective: TThe objective of this study is to determine the prevalence of hearing loss and risk factors among full-term inborn neonates delivered in a University Teaching Hospital with transient evoked otoacoustic emission (TEOAE). Materials and Methods: All full-term neonates delivered in a University Teaching Hospital were included in this prospective cross-sectional study. The hospital’s ethical committee gave approval. The researcher obtained informed consent from the parents and administered a questionnaire for demographic, prenatal, and postnatal data. A comprehensive head and neck examination preceded the preliminary otoscopy. With the help of a hand-held otodynamic otoport, Neonatal Hearing Screening Program otoacoustic emission (OAE), each ear’s hearing was assessed. Statistical Product and Service Solutions (SPSS) version 22.0 was used to analyse the data. Results: 150 full-term neonates were screened, of which 72 (48%) were males and 78 (52%) were females. Neonates that failed the TEOAE in both ears were 12 (8%). 18 (12%) neonates had a refer in right ear only, while 24 (16%) had a refer in the left ear only. The only significant risk factor with a referral outcome of TEOAE was family history of childhood hearing loss (23.1%). Conclusion: This study found a high prevalence (8%) of failed TEOAE of full-term neonates delivered in our hospital with a significant risk factor of family history of childhood hearing loss.

Abstract
Background Glutaric aciduria type 1 (GA-1) is a rare disease connected with speech delay and neurological deficits. However, the audiological and otologic profiles of GA-1 have not yet been fully characterized. To our knowledge, this is the largest study of comprehensive audiological and otologic evaluation in patients with GA-1 to date.
Methods Thirteen patients diagnosed with GA-1 between January 1994 and December 2019 with audiological, radiological and genetic manifestations were retrospectively analyzed. Hearing tests were performed in all patients. MRI was performed for radiological evaluation. Results Hearing loss was found in 76.9% (10/13) of GA-1 patients, including slight hearing loss in 46.1% (6/13) of patients, mild hearing loss in 15.4% (2/13) of patients, and moderate hearing loss in 7.7% (1/13) of patients. Normal hearing thresholds were seen in 23% (3/13) of patients. Patients with intensive care unit (ICU) admission history showed significantly worse hearing than those without (29.17 ± 12.47 vs 13.56 ± 3.93 dB HL, 95% CI 2.92–24.70, p = 0.0176). One patient had moderate sensorineural hearing loss and a past history of acute encephalopathic crisis. No usual causative gene mutations associated with hearing loss were found in these patients. MRI showed a normal vestibulocochlear apparatus and cochlear nerve. One patient with extensive injury of the basal ganglia on MRI after acute encephalopathic crisis was found to have moderate sensorineural hearing loss. Two patients with disability scores above 5 were found to have mild to moderate hearing impairment. No obvious correlation between macrocephaly and hearing loss was found. Conclusion A high prevalence of hearing impairment is found in GA-1 patients. Adequate audiological evaluation is essential for these patients, especially for those after encephalopathic crises or with ICU admission history.

Abstract
Early detection of hearing loss in neonates is important for normal language development, especially for infants admitted to the neonatal intensive care unit (NICU) because the infants in NICU have a higher incidence of hearing loss than healthy infants. However, the risk factors of hearing loss in infants admitted to the NICU have not been fully acknowledged, especially in Korea, although they may vary according to the circumstances of each country and hospital. In this study, the risk factors of hearing loss in NICU infants were analyzed by using the newborn hearing screening (NHS) and the diagnostic auditory brainstem response (ABR) test results from a 13-year period. A retrospective chart review was performed using a list of NICU infants who had performed NHS from 2004 to 2017 (n = 2404) in a university hospital in Korea. For the hearing loss group, the hearing threshold was defined as 35 dB nHL or more in the ABR test performed in infants with a 'refer' result in the NHS. A four multiple number of infants who had passed the NHS test and matched the age and gender of the hearing loss group were taken as the control group. Various patient factors and treatment factors were taken as hearing loss related variables and were analyzed and compared. From the 2404 infants involved, the prevalence of hearing loss was 1.8% (n = 43). A comparison between the hearing loss group (n = 43) and the control group (n = 172) revealed that history of sepsis, peak total bilirubin, duration of vancomycin use, days of phototherapy, and exposure to loop-inhibiting diuretics were significantly different, and can be verified as significant risk factors for hearing loss in NICU infants.

Abstract
INTRODUCTION Hearing loss is one of the most common congenital disabilities in neonates. The aims of this study were to investigate the prevalence of hearing loss and identify the most significant risk factor in neonates hospitalized at the Neonatal Intensive Care Unit (NICU). METHODS This cross-sectional study involved 530 neonates admitted to NICU Abuzar Hospital with risk factors for hearing loss based on Joint Committee of Infant Hearing (JCIH). The hearing screening tests include transient evoked otoacoustic emissions (TEOAES) and the automated auditory brain stem response (AABR). For infants with abnormal AABR and TEOAE results, the Auditory Brainstem Response (ABR) and Auditory Steady-State Responses (ASSR) tests were performed. RESULT Of 530 infants, 27 (5.09%) were diagnosed with different types of hearing loss. Ototoxic drugs, hyperbilirubinemia requiring exchange transfusion, asphyxia, low weight birth, Apgar score < 5, and a kinship marriage of parents were significant risk factors for hearing loss in our study population. CONCLUSION Due to the high prevalence of hearing loss in the NICU, it is recommended that a hearing screening program be performed for all infants admitted to the NICU. Implement a comprehensive plan for neonatal hearing screening for early detection and intervention of hearing loss is essential.

Abstract
OBJECTIVES To describe the nature, associated risk factors and age of diagnosis for childhood hearing loss in a South African cohort from the Western Cape Province. METHODS A retrospective review of clinical data from children under six years of age with confirmed hearing loss at Red Cross War Memorial Children's Hospital (RCWMCH) was conducted between 1 January 2019 and 31 July 2019. Data collected included demographic information, type and degree of hearing loss, documented risk factors associated with hearing loss, and age of suspicion and diagnosis of hearing loss. RESULTS The study sample included 240 children with hearing loss, with a mean age of 42 months (21.8 SD; range 2-72). More than two thirds (68.3%) of the children presented with bilateral hearing loss. The majority presented with conductive hearing loss (64.6%), followed by sensorineural (28.7%) and mixed hearing loss (3.3%) or auditory neuropathy spectrum disorder (3.3%). More than half (51.8%) of the bilateral sensorineural hearing losses were of a profound degree. The most prominent risk factor for conductive hearing loss was otitis media, for sensorineural hearing loss it was a family history of childhood hearing loss, and for auditory neuropathy spectrum disorder it was hyperbilirubinaemia. Approximately one third of patients (27.1%) with sensorineural hearing loss did not have any associated risk factors. The mean age of diagnosis of permanent congenital or early-onset hearing loss was 31.4 months (22.8 SD; range 2-72), with a mean delay of nine months (13.2 SD; range 0-60) between age of suspicion and diagnosis of hearing loss (n = 93). CONCLUSIONS The large proportion of preventable hearing losses in this sample highlights the importance of maximising primary health care efforts to treat preventable causes timeously. Age of diagnosis of permanent congenital or early-onset hearing loss was severely delayed undermining prospects of positive outcomes through early intervention. Infant hearing screening services in the public health sector of South Africa should be prioritised alongside primary health care efforts to reduce preventable risks for hearing loss.

Abstract
Objective To study the prevalence of hearing loss (HL) and to identify the possible risk factors causing HL. Methods This retrospective study was conducted from January 2014-December 2016 at a tertiary hospital in Malaysia. All neonates admitted to the neonatal intensive care unit (NICU), Universiti Kebangsaan Malaysia Medical Centre (UKMMC) were screened with a two-step protocol using an automated auditory brain response (AABR) and/or Otoacoustic Emission and auditory brain response (ABR). Descriptive analysis was used for the prevalence of HL, degree of HL and number of risk factors per infant. Results A total of 2713 babies underwent hearing screening in NICU was enrolled in this study. Two thousand six hundred eight (96%) babies passed the screening test and 214 (4%) babies required further diagnostic test. Only 105 (49%) babies completed diagnostic tests. Out of 105 babies, 40 (38.1%) babies had HL. Mild HL was the commonest HL with 22 (55%), moderate HL was in seven babies (17.5%), severe HL in two babies (5%), and profound HL in nine babies (22.5%). The presence of craniofacial anomalies was the only significant independent risk factor for HL with p<0.05 with an odds ratio of 0.105 CI 95% [0.028-0.389]. Of Babies with the presence of three or more risk factors, 100% of them had HL.There was an increased risk of hearing loss in those with craniofacial anomalies up to 11 times higher compared to those without such anomalies. Conclusion The prevalence of HL among the NICU babies was 1.5% and mild HL was the commonest degree of HL (55%).

Abstract
OBJECTIVE To assess the association between gentamicin exposure in the neonatal period and hearing in school age. METHODS This study included children exposed to a high-dose (6 mg/kg) gentamicin regimen as neonates (2004-2012), invited for follow-up at school age, and a healthy age-matched control group. We assessed hearing with pure tone audiometry including the extended high-frequency (EHF) range. Outcomes were average hearing thresholds in the midfrequencies (0.5-4 kHz) and the EHFs (9-16 kHz). The measures of gentamicin exposure were cumulative dose and highest trough plasma concentration. We used linear regression models to assess the impact of gentamicin exposure, and other peri- and postnatal morbidities, on hearing thresholds. RESULTS A total of 219 gentamicin-exposed and 33 healthy-control children were included in the audiological analysis. In the gentamicin cohort, 39 (17%) had a birth weight <1500 g. Median cumulative doses and trough plasma concentrations were 30 (interquartile range 24-42) mg/kg and 1.0 (interquartile range 0.7-1.2) mg/L, respectively. Median hearing thresholds for the midfrequencies and the EHFs were 2.5 (0 to 6.3) dB hearing level and -1.7 (-5.0 to 5.0) dB hearing level, both of which were within the normal range. In an adjusted analysis, increasing hearing thresholds were associated with lower birth weight and postnatal middle-ear disease but not level of gentamicin exposure. After adjusting for birth weight, there was no difference in hearing threshold between the gentamicin-exposed cohort and healthy controls. CONCLUSIONS Exposure to a high-dose gentamicin regimen in the neonatal period was not associated with an increase in hearing thresholds in schoolchildren being able to complete audiometry.

Abstract
BACKGROUND We aimed to analyse the outcome of universal newborn hearing screening (UNHS) and high-risk hearing screening in neonatal intensive care unit (NICU) graduates in a tertiary care unit. METHODS The hearing screen programme comprises a 2-stage automated auditory brainstem response protocol followed by a high-risk hearing screen at 3-6 months. This study is a retrospective study of NICU graduates born between April 2002 and December 2009. Data on hearing screening, audiological assessment, and management were extracted from a computerized data management system (HITRACK). RESULTS Of 100,225 newborn infants, 2.9% were admitted to the NICU during the study period. The overall incidence of hearing loss (HL) of any type/severity was 35/1,000 infants. Of infants with HL, 92.4% had their first automated auditory brainstem response at/before 1 month of corrected age. The incidence of congenital permanent HL identified by the UNHS was 15.4/1,000. The corrected median age of diagnosis was 4.5 months (1-23.5 months). Of 2,552 NICU graduates who passed the UNHS, 75.5% were retested at 3-6 months of life. Twelve infants with permanent late-onset HL were identified, raising the overall incidence of permanent HL to 19.9/1,000; 1.1/1,000 had auditory neuropathy. Of the 92 infants with HL, 89 (96.7%) had multiple risk factors. CONCLUSIONS There is a high incidence of HL in NICU graduates; 22.6% were late in onset. An early rescreen in those who pass the UNHS is a beneficial step for this high risk population.

Abstract
PURPOSE The current study aimed to describe the medical case history factors in a group of neonates admitted to high care and Kangaroo Mother Care wards at two hospitals in Gauteng, South Africa and to explore the relationship between specific case history factors and audiological outcomes. METHODS This study was part of a bigger study titled "Early detection of hearing loss: exploring risk-based hearing screening within a developing country context" where all case history data were recorded from participant medical files at the time of an initial hearing screening, through the use of a case history form that was developed for this study. Results were analyzed using descriptive statistics. The relationship between case history factors and audiological outcomes was analyzed using Fisher's exact test. RESULTS Findings revealed that, of all the case history data, preterm birth (95.7%), exposure to ototoxic medication (87.7%), neonatal jaundice (NNJ) (80.6%), and birthweight below 1500 g (66.7%) were the most frequently occurring case history factors in this South African sample. No statistically significant association was found between these frequently occurring case history factors and the repeat hearing screening outcomes in this sample. CONCLUSIONS Risk factors for hearing impairment cannot be viewed in isolation but should be considered in relation to their interaction with multiple other risk factors. Contextually understanding the profile of high risk has implications for medical intervention, as well as for the field of Audiology where planning for early identification and intervention services for hearing impairment is vital. Such contextually relevant evidence allows for a snap shot of how this population presents, what their needs and requirements are, and their possible future requirements; hence, raising important planning implications for the department of health and for targeted newborn hearing screening as well as early childhood intervention within the South African context.

Abstract
OBJECTIVES Aim of this study is to report and discuss the results of 4 years of Newborn hearing screening (NHS) program at the Neonatal Intensive Care Unit (NICU), particularly evaluating the clinical ABR results. METHODS Retrospective study. NHS data from NICU newborns, admitted for ≥5 days, in the period from January 1st, 2013 and December 31st, 2016, were retrieved and analyzed. NHS results were classified as following: (i) "pass" when both ears for both the a-TEOAE (automated Transient-Evoked Otoacoustic Emissions) and the a-ABR (automated Auditory Brainstem Response) protocol resulted as "pass"; (ii) "fail" when one ear, at either one of the two performed tests resulted as "fail"; (iii) "missing" when the newborns were not tested with both protocols. All "fail" and "missing" newborns were retested (with both tests): in the case of a second "fail" result, a clinical ABR was performed within a period of 3 months. RESULTS A total of 1191 newborns were screened. From those, 1044/1191 resulted as "pass", 108/1191 as "fail", and 39/1191 as "missing". During the re-testing of these 147 newborns, 43 were assigned as "missing", 63 were assigned as "pass" (showing bilaterally a wave V identifiable within 30 dB nHL) and 25 failed the retest and/or did not present an identifiable wave V within 30 dB nHL. Among the 147 retested infants, we identified a group of 16 subjects who resulted as NHS "refer" and who, during the audiological follow-up, showed either: (i) a unilateral or bilateral wave V identifiable over 30 dB nHL, at the first clinical ABR assessment; or (ii) a bilateral wave V identifiable within 30 dB nHL, in a following clinical ABR test during the first year of life. These 16 subjects were defined to have an 'Auditory Brainstem Maturation' issue. CONCLUSIONS A possible "maturation" of the ABR response (and therefore of the auditory pathway) has been hypothesised in 16 out of 1191 infants (1.3%). A delay of the auditory pathway maturation in preterm babies compared to term newborns has already been suggested in the literature. A possible delay of the NHS retest could be considered, in selected cases, with significant savings in economic resources and parental anxiety.

Abstract
AIM To explore how auditory and speech function developed post-cochlear implantation (pCI) in prelingually deaf children with white matter lesions (WML). METHOD Patients (41 males, 29 females; mean age at implantation 2y 11mo [SD 7.5mo], range 1y 8mo-5y) were divided into the following groups according to preoperative brain magnetic resonance imaging evaluation: mild WML, moderate WML, severe WML, and control. We assessed auditory and speech performance at baseline, 6 months, 12 months, and 24 months pCI. As well as auditory event-related potentials, topographic maps and electroencephalography source imaging were recorded and analysed at 24 months pCI. RESULTS For children with WML (any level), postoperative auditory or speech performance at 6 months was significantly below that of control participants. After stratification, auditory and speech performance was highly related to WML grading. Auditory or speech performance in mild WML or control groups was comparatively better than the moderate WML and severe WML groups. The recovery rate of speech performance fell behind that of the auditory perception. With the increasing severity of WML, N1 amplitude was significantly smaller with a consistent presentation in the topographic map, which was similar in the mild WML and control group. The dominant auditory centre was activated in the control or mild WML groups, but not in the moderate WML and severe WML groups. INTERPRETATION WML gradually affect auditory and speech development, and electrophysiological performance pCI in prelingually deaf children. WHAT THIS PAPER ADDS Auditory and speech performance in prelingually deaf children with white matter lesions (WML) was significantly worse than those without WML. Postoperative auditory and speech performance in children with WML was highly related to WML grading. Grand N1 amplitude in auditory event-related potentials was negatively related to the severity of WML. Non-dominant areas close to the auditory cortex were potentially activated in severe WML.

Abstract
A retrospective review of children with confirmed hearing loss identified through universal newborn hearing screening (UNHS) in Virginia from 2010 to 2014 was conducted in order to compare the incidence of Joint Committee on Infant Hearing (JCIH) risk factors in children with unilateral hearing loss (UHL) to bilateral hearing loss (BHL). Over the 5-year study period, 1004 children (0.20% of all births) developed a confirmed hearing loss, with 544 (51%) children having at least one JCIH risk factor. Overall, 18% of children with confirmed hearing loss initially passed UNHS. Of all children with risk factors, 226 (42%) demonstrated UHL and 318 (58%) had BHL. The most common risk factors for UHL were neonatal indicators (69%), craniofacial anomalies (30%), stigmata of HL syndromes (14%), and family history (14%). The most common risk factors in BHL were neonatal indicators (49%), family history (27%), stigmata of HL syndromes (19%), and craniofacial anomalies (16%). Children with the risk factor for positive family history were more likely to have BHL, while those with craniofacial anomalies were more likely to have UHL ( P < .001). Neonatal indicators were the most commonly identified risk factor in both UHL and BHL populations. Children with UHL were significantly more likely to have craniofacial anomalies, while children with BHL were more likely to have a family history of hearing loss. Further studies assessing the etiology underlying the hearing loss and risk factor associations are warranted.

Abstract
BACKGROUND We aimed to identify prenatal and postnatal risk factors associated with abnormal newborn hearing screen (NHS) results and subsequently confirmed sensorineural hearing loss (SNHL) in preterm twin neonates. METHODS Electronic medical records of 159 twin neonates who were born alive after ≤32 weeks were retrospectively reviewed for hearing loss in both ears. Histopathologic examination of the placenta was performed and clinical data, including method of conception and factors specific to twins, were retrieved from a computerized perinatal database. The main outcome measure was failure to pass the NHS test. The generalized estimation equations model was used for twins. RESULTS Thirty-two neonates (20.1%) had a "refer" result, and, on the confirmation test, permanent SNHL was identified in 4.4% (7/159) of all neonates. Neonates who had a "refer" result on the NHS test were more likely to be of lower birth weight, more likely to have been conceived with the use of in vitro fertilization (IVF), and more likely to have higher rates of intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia. However, monochorionic placentation, death of the co-twin, or being born first was not associated with a "refer" result on the NHS test. Multivariable logistic regression revealed that conception after IVF and the presence of IVH were the only variables to be statistically significantly associated with "refer" on the NHS test. No parameters studied were found to be significantly different between the SNHL and no SNHL groups, probably because of the relatively small number of cases of SNHL. CONCLUSION In preterm twin newborns, IVF and the presence of IVH were independently associated with an increased risk of abnormal NHS results, whereas the factors specific to twins were not associated with abnormal NHS results.

Abstract
Objective We aimed to determine whether elevated levels of various inflammatory and immune proteins in umbilical cord blood are associated with an increased risk of newborn hearing screening (NHS) test failure in preterm neonates. Methods This retrospective cohort study included 127 premature singleton infants who were born at ≤33.6 weeks. Umbilical cord plasma at birth was assayed for interleukin (IL)-6, complement C3a and C5a, matrix metalloproteinase (MMP)-9, macrophage colony-stimulating factor (M-CSF), and endostatin levels using ELISA kits. Neonatal blood C-reactive protein (CRP) levels were measured within 2 hours of birth. The primary outcome measure was a uni- or bilateral refer result on an NHS test. Univariate and multivariate analyses were applied. Results Fifteen (11.8%) infants failed the NHS test. In the univariate analyses, high IL-6 and low C3a levels in umbilical cord plasma, funisitis, and an elevated CRP level (>5 mg/L) in the immediate postnatal period were significantly associated with NHS test failure. However, the levels of umbilical cord plasma MMP-9, C5a, M-CSF, and endostatin were not significantly different between infants who passed and those who failed the NHS test. Multiple logistic regression analyses indicated that elevated umbilical cord plasma C3a levels were independently associated with a reduced risk of NHS test failure, whereas elevated levels of umbilical cord plasma IL-6 and high CRP levels in the immediate postnatal period were significantly associated with NHS test failure. Conclusions Our data demonstrated that in preterm neonates, a systemic fetal inflammatory response reflected by umbilical cord plasma IL-6 and immediate postnatal CRP levels may contribute to the risk for NHS test failure, whereas the changes in complement activation fragments initiated in utero may have protective effect of hearing screen failure.

Abstract
There are a wide variety of hearing impairments that part of it is auditory neuropathy/dys-synchrony (AN/AD). So, the object of this study was determination the prevalence and causes of AN/AD in children with hearing impairment. This study was a descriptive cross-sectional survey. The sample size consisted of 105 hearing impairment children. All them were under hearing screening tests (tympanometry), distortion and transient evoked otoacoustic emissions (DPOAEs + TEOAE) and automated auditory brainstem response (AABR). If they were suspected to AN/AD, for complete diagnostic measurements were referred to our hospital. Four cases (8 ears) with AN/AD were diagnosed, which had an average age 37 months (SD = 8.67). So, the prevalence of AN/AD was 3.8 % among hearing impaired children. The findings of this study showed that there are the relationships between AN/AD and fluctuating hearing loss, acoustic reflex, high bilirubin, blood exchange after birth, neonatal intensive (NICU) care unit (P < 0.05). The simultaneous use of both ABR and OAE tests in the birth screening provide much more useful information than when each of these tests is used alone.

Abstract
OBJECTIVE The aim of this study was to discover Turkish regional differences in the risk factors of newborn hearing loss. METHOD A multi-centered retrospective design was used. A total of 443 children, registered to the national newborn hearing screening programme, with bilateral hearing loss, from five different regions of Turkey, were evaluated in terms of the types of hearing loss, the degree of hearing loss, the types of risk factors, parental consanguinity, age at diagnosis and age of auditory intervention, respectively. RESULTS There was no significant difference in the prevalence of hearing loss between regions (χ2 = 3.210, P = 0.523). Symmetric Sensorineural Hearing Loss (SSHL) was the most common type of HL in all regions (91.8%). Profound HL was the most common degree of HL in all regions (46.2%). There were statistically significant differences between regions in terms of types of HL (χ2 = 14.151, P = 0.000). As a total, 323 (72.9%) of subjects did not have any risk factors. There were statistically significant differences between regions in terms of the types of risk factors (pre, peri and post-natal) for SSNHL (χ2 = 16.095, P = 0.000). For all regions, the age of diagnosis was convenient with the JCIH criteria. However the age of hearing aid application was prolonged in some regions. There were statistically significant differences between regions in terms of the age of diagnosis (χ2 = 93.570, P = 0.000) and the age of auditory intervention (χ2 = 47.323, P = 0.000). The confounding effects of gender, age of diagnosis, age of hearing aids applications, HL in the family, types of risk factors for HL on SSNHL were detected. CONCLUSION To reach the goal of a high quality newborn hearing screening, there is a need to develop an evidence-based standard for follow up guideline. In addition, risk factors should be re-evaluated according to regional differences and all regions should take their own precautions according to their evidence based data.

Abstract
The aim of the paper is to describe the knowledge of mothers in Durban, South Africa, regarding risk factors of hearing loss in infants and their awareness of audiology services, and to describe their cultural beliefs about the risk factors for hearing loss in infants. A descriptive survey design with quantitative methods of analysis were used. Conveniently sampled mothers (n=102) receiving postnatal care for their infants from eight provincial clinics within Durban consented to participate, yielding a response rate of 48%. A questionnaire was used to collect the data and the Cronbach α was calculated yielding a score of 0.835, indicating good internal consistency and reliability of the questionnaire. Sixty percent of the mothers were aware of risk factors, such as middle ear infections, ototoxic medication and consumption of alcohol during pregnancy. Seventy percent were unaware that NICU/mechanical ventilation for more than 5 days, prematurity, rubella and jaundice are considered risk factors for hearing loss, implying a need to create awareness amongst mothers regarding such risk factors. Sixty percent (n=62) believed that bewitchment and ancestral curses can cause hearing loss. Cultural beliefs were associated with hearing loss, therefore, health professionals need to demonstrate cultural competence when providing audiology services, especially in a culturally and linguistically diverse countries such as South Africa. Although the mothers had an average knowledge about risk factors, two thirds did not know which professional to seek help from. There is a need to create awareness amongst mothers regarding the risk factors of infant hearing loss as well as audiology services in order to facilitate early detection and intervention. There is a need for health professionals to demonstrate cultural competence when working with their patients.

Abstract
PURPOSE In this study, we examined the association between risk factors for hearing loss and early childhood hearing status (normal hearing, congenital hearing loss, or delayed-onset hearing loss). Follow-up rates of audiologic care following passed or referred birth screens for children with risk factors were also examined. METHOD A retrospective data review was completed on 115,039 children born from 2010 to 2012. Data analyses included prevalence rates, odds ratios, and Fisher exact tests of statistical significance. RESULTS Ninety percent of children were born with no risk factors for hearing loss; of those, 99.9% demonstrated normal hearing by 3 years of age. Of the 10% of children born with risk factors, 96.3% demonstrated normal hearing by age 3, 1.4% presented with congenital hearing loss, and 2.3% demonstrated permanent hearing loss by age 3. Factors that placed children at the highest risk of congenital hearing impairment were neurodegenerative disorders, syndromes, and congenital infections. Factors that placed children at the highest risk of developing permanent postnatal hearing loss were congenital cytomegalovirus, syndromes, and craniofacial anomalies. CONCLUSIONS Certain risk factors place a child at significantly greater risk of congenital hearing impairment or developing permanent hearing loss by age 3. Follow-up diagnostic testing should remain a priority for children with certain risk factors for hearing loss.

AUNA2: A Novel Type of Non-Syndromic Slowly Progressive Auditory Synaptopathy/Auditory Neuropathy with Autosomal-Dominant Inheritance. Audiol Neurootol 2017; 22:30-40. [PMID: 28601886 DOI: 10.1159/000474929] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2016] [Accepted: 03/31/2017] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Auditory synaptopathy/neuropathy (AS/AN) is a heterogeneous disorder, which may be caused by environmental factors like postnatal hyperbilirubinemia or by genetic factors. The genetic forms are subdivided into syndromic and non-syndromic types, and show different inheritance patterns with a strong preponderance of autosomal-recessive forms. To date, only a single locus for non-syndromic autosomal-dominant AS/AN (AUNA1) has been reported in a single family, in which a non-coding DIAPH3 mutation was subsequently described as causative. MATERIALS AND METHODS Here, we report detailed clinical data on a large German AS/AN family with slowly progressive postlingual hearing loss. Affected family members developed their first symptoms in their second decade. Moderate hearing loss in the fourth decade then progressed to profound hearing impairment in older family members. Comprehensive audiological and neurological tests were performed in the affected family members. Genetic testing comprised linkage analyses with polymorphic markers and a genome-wide linkage analysis using the Affymetrix GeneChip® Human Mapping 250K. RESULTS AND CONCLUSION We identified a large family with autosomal-dominant AS/AN. By means of linkage analyses, the AUNA1 locus was excluded, and putatively linked regions on chromosomal bands 12q24 and 13q34 were identified as likely carrying the second locus for autosomal-dominant AS/AN (AUNA2). AUNA2 is associated with a slowly progressive postlingual hearing loss without any evidence for additional symptoms in other organ systems.

Abstract
BACKGROUND Sensorineural hearing loss (SNHL) is a multifactorial disease that more frequently affects preterm newborns. Although a number of maternal conditions have been reported to be associated with preterm birth, little information is available concerning maternal risk factors for the development of SNHL. We aimed to identify maternal and placental risk factors associated with a "refer" result on the newborn hearing screening (NHS) test and subsequently confirmed SNHL in very preterm neonates. METHODS This retrospective cohort study included 267 singleton neonates who were born alive after ≤ 32 weeks. Histopathologic examination of the placenta was performed, and clinical data were retrieved from a computerized perinatal database. Cases with two abnormal findings, "refer" on the NHS test, and presence of SNHL on the confirmation test were retrospectively reviewed based on electronic medical records. RESULTS Forty-two neonates (15.7%) showed a "refer" result, and, on the confirmation test, permanent SNHL was identified in 1.87% (5/267) of all neonates. Multivariate regression analysis revealed that the presence of funisitis was independently associated with a "refer" on the NHS test, whereas use of antenatal corticosteroids was statistically significantly associated with a reduced incidence of "refer" on the screening test. Neither histologic chorioamnionitis nor prematurity (as defined by low gestational age and birth weight) was associated with a "refer" on the NHS test. By contrast, multivariate analysis with occurrence of SNHL as a dependent variable identified no significant associations with the parameters studied, probably owing to the small total number of neonates with permanent SNHL. CONCLUSION Presence of funisitis was significantly and independently associated with increased risk of abnormal NHS results, while administration of antenatal corticosteroids was related to a normal NHS result. These findings support the hypothesis that a systemic fetal inflammatory response, manifested as funisitis, might play a role in the pathogenesis of SNHL in preterm neonates.

Abstract
OBJECTIVE The aim of this study was to analyze the hearing screening program among preterm infants as well as to identify risk factors associated with failing primary newborn hearing screening. METHODS The retrospectively selected population included all preterm infants who had primary hearing screening in a neonatal ward from January 1st, 2013 to December 31st, 2015 at West China Second University Hospital, Sichuan University. The newborn hearing screening (NHS) procedure was performed in all preterm infants by automated auditory brainstem response (AABR). Infants who failed the primary hearing screening received a second screening at 42 days after birth. Infants who failed both tests were referred to a tertiary audiology center for diagnostic confirmation and management before 6 months of age. The final diagnosis for referred infants was obtained by telephone follow-up. The risk factors associated with failure to pass the primary hearing screen were evaluated and analyzed for preterm infants. RESULTS Among 2291 preterm infants recruited, 155 infants (6.8%) failed the primary hearing screening with an abnormal AABR. Of these 155 infants, 113 (72.9%) passed the secondary screening. At the end of the follow-up, 1 infant (0.04%) was diagnosed with hearing loss, 3 infants had delayed language development, and 40 infants were lost to follow up. Multivariate regression analysis revealed that gestational age ≤32 weeks (Odds ratio [OR] = 2.093, 95% confidence interval [CI] 1.370-3.196), super hyperbilirubinemia (≥25 mg/dl) (OR = 3.560, 95% CI 1.009-12.560), and respiratory failure (OR = 1.971, 95% CI 1.188-3.265) were associated with failure to pass newborn hearing screening. CONCLUSION The prevalence of failure to pass primary hearing screening among preterm infants was 6.8% in our study, and we found a relatively low prevalence of hearing loss (0.04%). Super hyperbilirubinemia, gestational age ≤32weeks, and respiratory failure were risk factors associated with failure of preterm infants to pass the primary hearing screening. Our results suggest that preterm infants with hyperbilirubinemia, gestational age ≤32 weeks, and respiratory failure should be closely followed.

Abstract
BACKGROUND Although we've made big strides in perinatal and neonatal care, auditory handicap remains a serious complication in those who were born very premature. OBJECTIVES The aim was to determine the prevalence and analyze possible risk factors of hearing impairment in very-low-birth-weight (VLBW) infants. MATERIALS AND METHODS This was a retrospective study by reviewing medical records of all VLBW infants (BW ≤ 1500 g) admitted to NICU of Chang Gung Children's Hospital over 2 years period from Jan. 2010 to 2011. Brainstem auditory evoked potentials (BAEP) hearing screening was performed at 3 months postnatal corrective age and repeated if failed the 1st time, then refer to ENT doctor if BAEP confirmed abnormal. All VLBW infants examined for hearing impairment were included and data were retrieved retrospectively and analyzed for neonatal risk factors using logistic regression. RESULTS Over the period, 309 VLBW infants were screened. Prevalence of uni- or bilateral hearing impairment was 3.9% (12/309; 95% CI 2.6-4.1). The mean corrective age on diagnosed of hearing impairment was 2.9 ± 1.1 (range 1-5) months. Mean gestational age was 27.9 weeks (SD 1.4) and mean birth weight was 1028 g (SD 180). By univariant analysis for hearing impairment, severe birth asphyxia, craniofacial anomalies, ventilator dependence, patent ductus arteriosus ligation, and use of postnatal ototoxins yielded good prediction of hearing impairment in this population. However, using multivariate analysis revealed that the only independent risk factors for hearing impairment were ototoxins (OR: 3.62; CI: 1.67-7.82), PDA ligation (OR: 4.96; CI: 2.34-10.52), craniofacial anomalies (OR: 3.42; CI: 1.70-6.88)and assisted prolonged use of oxygen at gestational age of >36 weeks (OR: 5.94; CI: 2.61-13.54). CONCLUSION The incidence of hearing impairment among VLBW infants was 3.9%. Prolonged supplemental oxygen use is a marker for predicting hearing impairment; this requires detailed analysis of the pathophysiologic features, to reduce the prevalence of hearing impairment.
