Cataloging Existing Hearing Loss Cohort Data to Guide the Development of Precision Medicine for Sensorineural Hearing Loss: A Systematic Review of Hearing Repositories

Recent breakthroughs in our understanding of sensorineural hearing loss etiology have encouraged the identification of novel hearing therapeutics, paving the way for precision hearing medicine. Critical to this field is the curation of health resources on hearing data. A systematic review of the literature was conducted to map existing (inter)national and regional datasets that include hearing data to inform the development of future hearing repositories. Systematic literature review was performed adhering to Preferred Reporting Items for Systematic Review and MetaAnalysis recommendations. Databases, including those from gray literature, were searched to identify publications reporting on phenotypic and/ or genotypic hearing data in May 2019. The databases reviewed were Medline, PubMed, Embase databases, and Google Scholar. Publications on local datasets were excluded. All hearing datasets identified in the screening process were noted. For each dataset, geography, context, objective, period of time run, numbers and demographics of participants, genomic data, hearing measures and instruments used were extracted and cataloged. One hundred and eighty-eight datasets were identified, containing hearing data on populations ranging from 100 to 1.39 million individuals, and all extracted data have been cataloged. This searchable resource has been made accessible online. This unique catalog provides an overview of existing datasets that contain valuable information on hearing. This can be used to inform the development of national and international patient data repositories for hearing loss and guide strategic collaboration between key stakeholder groups, pivotal to the delivery and development of sensorineural hearing loss precision diagnostics and treatments

Tailoring surgical interventions to treat obstructive sleep apnoea: one size does not fit all

While continuous positive airway pressure (CPAP) remains the gold standard treatment of choice in patients with moderate or severe obstructive sleep apnoea (OSA), surgery has been established as a means to improve compliance and facilitate the use of CPAP, both of which are potential pitfalls in the efficacy of this treatment modality. In a minority of cases, with obvious oropharyngeal anatomical obstruction, corrective surgery may completely alleviate the need for CPAP treatment. In this review, we summarise clinical assessment, surgical options, discuss potential new treatments, and outline the importance of investigating and addressing the multiple anatomical levels that can contribute to OSA. Research into effectiveness of these procedures is rapidly accumulating, and surgery can be an effective treatment. However, given the myriad of options available and multiple levels of anatomical pathology that can present, it is imperative that correctly selected patients are matched with the most appropriate treatment for the best outcomes. Key points OSA is an increasingly prevalent disorder which has significant systemic effects if left untreated. Anatomical abnormalities can be corrected surgically to good effect with a growing and robust evidence base. Drug-induced sleep endoscopy is a key tool in the otolaryngologist's armamentarium to tailor specific surgery to address specific anatomical concerns, and to facilitate appropriate patient selection. Multilevel surgical approaches are often indicated instead of a “one size fits all” model. Educational aims To discuss how to assess patients presenting with OSA in clinic, from an otorhinolaryngology perspective. To discuss the indications for intervention. To provide an overview of nonsurgical interventions for treating OSA, with evidence. To discuss the different surgical modalities available for treatment of OSA, with evidence
