Study Objectives: The use of sleep tracking devices is increasing as people become more aware of the importance of sleep and interested in monitoring their patterns. With many devices on the market, we conducted a meta-analysis comparing sleep scoring data from consumer wrist-worn sleep tracking devices with polysomnography to validate the accuracy of these devices.

Methods: We retrieved studies from the databases of SCOPUS, EMBASE, Cochrane Library, PubMed, Web of Science, and KoreaMed and OVID Medline up to March 2024.

Objective: Polysomnography (PSG) is unique in diagnosing sleep disorders, notably obstructive sleep apnea (OSA). Despite its advantages, manual PSG data grading is time-consuming and laborious. Thus, this research evaluated a deep learning-based automated scoring system for respiratory events in sleep-disordered breathing patients.

The relationship between obstructive sleep apnea (OSA) and chronic rhinosinusitis (CRS) has not yet been fully elucidated. Therefore, the objective of this study was to evaluate the connection between OSA risk and CRS by investigating associations between the STOP-Bang questionnaire and presence of CRS in a nationwide, population-based study. This is a cross-sectional study based on the Korean National Health and Nutrition Examination Survey (KNHANES).

Objectives: The aim of this study was to evaluate the validity of a modified STOP-Bang questionnaire with different body mass index reference as a screening tool for obstructive sleep apnea in Korean population.

Methods: The medical records of 1417 participants who underwent overnight Level I polysomnography were retrospectively analyzed. Predictive parameters were calculated for each of the 3 groups classified by obstructive sleep apnea severity with a cut-off value of 3 or 4.

Background And Objectives: In the past, palate surgery, such as uvulopalatopharyngoplasty (UPPP), was widely performed to treat obstructive sleep apnea (OSA). However, since the introduction of reimbursement for positive airway pressure (PAP) therapy in 2018, it is believed that the frequency of these operations has significantly declined. Despite this, there are currently no definitive data to support this assertion.

Article Synopsis
  • - This study aimed to analyze the safety and effectiveness of a digital therapy for insomnia called dSIBT-I, comparing it with another digital therapy, dCBT-I, at Asan Medical Center with 50 participants over one month.
  • - Both treatments showed significant improvements in sleep scores after four weeks, but there was no major difference between the two therapies in overall effectiveness.
  • - Notably, at the two-week mark, dSIBT-I outperformed dCBT-I in reducing insomnia severity and had no reported adverse events, suggesting it's a safe and effective option for quick relief.

Limited palatal muscle resection (PMR) is a surgical technique employed to alleviate respiratory disturbances in obstructive sleep apnea (OSA) patients with retropalatal narrowing by reducing soft palate volume and tightening the muscles. Although some previous publications have demonstrated the effectiveness of limited PMR, the overall efficacy and therapeutic role of limited PMR for the treatment of OSA remain uncertain. This study utilized meta-analysis and a systematic literature review to estimate the overall effectiveness of limited PMR in treating OSA.

Introduction: Obstructive sleep apnea (OSA) is known to increase the risk of various cancers. By analyzing the Korea National Health Insurance Service (KNHIS) registry, the impact of OSA on the lung cancer incidence was analyzed in a retrospective cohort group.

Methods: A retrospective cohort of adult patients newly registered with OSA in the KNHIS data from 2007 to 2017 was included and observed until December 2019 (12 years).

Obstructive sleep apnea (OSA) has been linked to an increased risk of acquiring many types of cancer. No data on the prevalence of testicular cancer in OSA patients have been reported in the literature. The goal of the present investigation is to find out the impact of OSA on the incidence of testicular cancer based on the Korea National Health Insurance Service (KNHIS) dataset.

It has been claimed that a tighter, reinforced quarantine strategy was advocated to reduce the transmission of coronavirus disease 2019 (COVID-19) during major outbreaks; however, there have been no prior quantitative studies examining the effectiveness and duration of such a reinforced quarantine. Consequently, the purpose of this research was to determine the impact of a "tighter, reinforced" quarantine during the third COVID-19 breakout wave in South Korea, which occurred between late 2020 and early 2021. The efficacy of the quarantine was determined by comparing the number of newly diagnosed COVID-19 patients between the "prediction model" and "actual observed data.

Obstructive sleep apnea (OSA) is a relatively common sleep disorder characterized by repetitive narrowing or obstruction of the upper airway, including the nasal cavity, pharynx, and larynx, during sleep. OSA can cause a variety of symptoms and/or complications, such as excessive daytime sleepiness, reduced concentration, hypertension, type II diabetes, and stroke. Accordingly, an accurate diagnosis and appropriate treatments are required for OSA.

Obstructive sleep apnea (OSA) is a common disorder characterized by upper airway obstruction during sleep. To reduce the morbidity of OSA, sleep specialists have explored various methods of managing the condition, including manifold positive airway pressure (PAP) techniques and surgical procedures. Nasal obstruction can cause significant discomfort during sleep, and it is likely that improving nasal obstruction would enhance the quality of life and PAP compliance of OSA patients.

There is controversy about the effect of pharyngeal surgery for obstructive sleep apnea (OSA) on positive airway pressure (PAP) adherence, and the related results of meta-analysis have not yet been available. Therefore, the purpose of this meta-analysis was to assess the effect of pharyngeal OSA surgery on PAP therapy parameters such as optimal pressure levels and usage time. We selected studies investigating optimal PAP levels or usage time before and after pharyngeal OSA surgery, regardless of the study design.

Background And Objectives: Little is known about studies evaluating positive airway pressure (PAP) compliance after re-prescription. Therefore, the aim of this study was to investigate PAP compliance after re-prescription in obstructive sleep apnea (OSA) patients who failed initial PAP therapy.

Methods: We retrospectively reviewed OSA patients who had received a re-prescription for PAP from March 2020 to June 2021.

Article Synopsis
  • The study investigated the effectiveness of respiratory mechanic instability (RMI) in diagnosing obstructive sleep apnea syndrome (OSAS) in children.
  • Researchers reviewed clinical and polysomnography (PSG) data from children across two hospitals, aiming to correlate RMI with sleep-related parameters.
  • The findings indicated that RMI parameters were significantly higher in children diagnosed with OSAS and correlated well with the severity of the condition, suggesting RMI could be a valuable diagnostic tool for pediatric OSAS.

The Korean Society of Otorhinolaryngology-Head and Neck Surgery and Korean Rhinologic Society appointed a guideline development group (GDG) to establish a clinical practice guideline, and the GDG developed a guideline for nasal irrigation for adult patients with chronic rhinosinusitis (CRS). The guideline focuses on knowledge gaps, practice variations, and clinical concerns associated with nasal irrigation. Nasal irrigation has been recommended as the first-line treatment for CRS in various guidelines, and its clinical effectiveness has been demonstrated through a number of studies with robust evidence.
