AI Article Synopsis

  • Randomized clinical trials do not currently support using continuous positive airway pressure for treating asymptomatic obstructive sleep apnea (OSA), especially in low-risk patients.
  • The OSCAR algorithm was proposed to help doctors manage asymptomatic moderate-severe OSA by focusing on weight loss, symptoms, and cardiovascular disease (CVD) risk.
  • Research found no significant difference in the risk of major adverse cardiovascular events (MACE) between patients with moderate-severe OSA and those without OSA, indicating that more studies are needed on this topic.

Article Abstract

Since randomized clinical trials currently do not support continuous positive airway pressure treatment of asymptomatic obstructive sleep apnea (OSA) we proposed the Obesity, Symptoms, and CARdiovascular assessment (OSCAR) algorithm to aid clinicians in the management of asymptomatic low-risk moderate-severe OSA, focusing on weight loss, symptoms and cardiovascular disease (CVD) risk assessment. Exploiting the data of the Sleep Heart Health Study we selected subjects with a body mass index (BMI) < 30 Kg/m, no history of CVD or sleepiness and compared 552 patients with moderate-severe OSA (OSCAR(-)) to 916 individuals without OSA (No-OSA). After adjusting for age, gender, and BMI, there was no significant difference in the risk of major adverse cardiovascular events (MACE) between OSCAR(-) and No-OSA (1.05; 95%CI 0.81-1.37). The study suggests that low-risk moderate-severe OSA patients may not have a greater risk of MACE compared to those without OSA and highlights the need for further research on this topic.

Association between obstructive sleep apnea and hyperuricemia/gout in the general population: a cross-sectional study.

BMC Musculoskelet Disord

January 2025

Department of Internal Medicine, Division of Rheumatology, Soonchunhyang University Seoul Hospital, Soonchunhyang University School of Medicine, Seoul, South Korea.

Background: Obstructive sleep apnea (OSA) is linked to various health conditions, including cardiovascular diseases and metabolic disorders. Hyperuricemia and gout may be associated with OSA, but large-scale studies on this are limited. This study aimed to investigate the association between hyperuricemia/gout and OSA using data from the Korea National Health and Nutrition Survey (KNHANES).

Background: Obstructive sleep apnea has been associated with various urinary system diseases, including prostatic hyperplasia and nocturia. Recently, it has been linked to prostate cancer. This study investigated the relationship between the apnea hypopnea index, prostate-specific antigen (PSA) levels, and changes in PSA.

Aim: In this study, it was aimed to determine the changes in the anatomic structures of individuals with obstructive sleep apnea syndrome (OSAS) classified according to the apnea-hypopnea index (AHI).

Materials And Methods: Individuals were divided into groups as group 1 (AHI=0, n=20), group 2 (AHI ˂5, n=20), group 3 (AHI=5-15, n=20), group 4 (AHI=16-30, n=20), group 5 (AHI ˃30, n=20). The individuals left lateral cervical vertebra radiographs were taken.

External rigid distraction is an established method for achieving subcranial Le Fort III advancement in severe syndromic craniosynostosis. Craniofacial surgeons commonly use halo-type devices for these corrections, as they allow for multiple vectors of pull and facilitate larger midfacial advancements. Although most complications related to their use involve pin displacement or infection, rare complications such as skull fractures have been reported.
