Background: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). Methods: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidencebased review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. Results: The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. Conclusion:This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.
ImportanceEarly identification of childhood hearing loss through newborn hearing screening mitigates permanent speech, language, and developmental delays, but many children are lost to follow-up or develop postnatal hearing loss. Early childhood hearing screening programs may help identify these children, but evidence on their outcomes is limited.ObjectiveTo assess outcomes from a low-income, preschool-based hearing screening program and risk factors for hearing loss in this population.Design, Setting, and ParticipantsA retrospective cohort study of 6820 children aged 2 to 6 years from urban, low-income public preschools who received hearing screening from July 1, 2015, to June 30, 2019, was performed using San Francisco Department of Public Health records. A multivariate logistic regression analyzed risk factors for hearing loss. Data analysis was conducted from January 14, 2020, to April 20, 2021.ExposuresAnnual single-visit, 2-tiered screening was implemented with conditioned play pure-tone audiometry (CPA) and distortion product otoacoustic emissions (OAEs).Main Outcomes and MeasuresRates of successful screening, referred screening, loss to follow-up, and hearing loss.ResultsOf 6820 children (age, 2-6 years) screened, 3425 (50.2%) were boys, 15% were White/non-Hispanic, and 48% had English as the primary home language. A total of 403 (5.9%) children were referred for full medical or audiologic evaluation after 2-tiered CPA/OAE screening. Only 24 children were unable to complete both CPA and OAE testing for a screening completion rate of 99.6%. After medical evaluation, 114 of 403 children (28.3%) passed hearing rescreening and 55 (13.6%) were lost to follow-up. The prevalence of conductive hearing loss was 2.9% (n = 195), and the prevalence of sensorineural hearing loss was 0.2% (n = 13). Primary language, race and ethnicity, and sex were not associated with rates of referral or hearing loss.Conclusions and RelevanceThe findings of this cohort study suggest that preschool-based screening programs can be a useful method to identify early childhood hearing loss and that teacher concerns are associated with final diagnostic hearing status.
Results: There was strong evidence of an association between doctor-patient communication scores and ethnicity. South Asian patients reported scores averaging 3.0 percentage points lower (scale of 0-100) than White British patients (95% CI −4.9 to −1.1, p=0.002). This difference reduced to 1.4 points (95% CI −3.1 to 0.4) after accounting for speaking a nonEnglish language at home; respondents who spoke a non-English language at home reported lower scores than English-speakers (adjusted difference 3.3 points, 95% CI −6.4 to −0.2).Conclusions: South Asian patients rate communication lower than White British patients within the same practices and with similar demographics. Our analysis further shows that this disparity is largely mediated by language.
Objectives: Hearing-loss gene panel testing (HLGPT) is increasingly accessible as a first-line test in determining the etiology of sensorineural hearing loss (SNHL) in children. A major advantage of HLGPT is early identification of syndromic forms of SNHL, especially Usher syndrome, prior to the development of overt syndromic phenotype, which may impact management and counseling. Here, we describe early ocular findings in children with clinically non-syndromic SNHL identified by HLGPT as having two variants associated with Usher Syndrome.Methods: A total of 184 children, ages 1 month -15 years of age, evaluated at one tertiary pediatric children's hospital for clinically non-syndromic SNHL, underwent next-generation sequencing of 150 genes involved in hearing loss. Children with two variants in genes associated with Usher syndrome were referred for evaluation by pediatric ophthalmology.Results: A total of 18/184 tested children had two variants in Usher syndrome-associated genes, including MYO7A, GPR98 (ADGRV1), USH2A, and PDZD7. SNHL varied from moderate to profound. 29% of the children who underwent clinical ophthalmology evaluation were found to have previously unidentified retinal abnormalities on retinal imaging or electroretinography consistent with inherited retinal degeneration.Conclusion: Among this ethnically and racially diverse pediatric population with apparently non-syndromic SNHL, HLGPT yielded a high proportion (10%) of children with two variants in genes associated with Usher syndrome. Early genetic testing allows early identification of variants conferring a diagnosis of Usher syndrome at a stage prior to visual symptoms. This allows for more informed genetic counseling, reproductive planning, and sensory deficit interventions.
