Evolution and Predictive Factors of Improvement of Obstructive Sleep Apnea in an Obese Population After Bariatric Surgery

Study Objectives:Our objectives were to determine in an obese population (body mass index> 35 kg/m2) the number of patients, after gastric bypass (GBP), who no longer met French Ministry of Health criteria for utilizing positive airway pressure (PAP), and the predictive factors of obstructive sleep apnea (OSA) improvement.Methods:Between June 2012 and August 2014 we diagnosed OSA in 129 incident patients requiring PAP therapy before GBP. A postoperative sleep recording was undertaken for 44 of these patients after a weight loss of at least 10%.Results:Most of the patients showed severe OSA with a mean [standard deviation] apnea-hypopnea index (AHI) of 52.8 [23.8] events/h. The body mass index was 46.1 [5.1] kg/m2. All the patients were treated via PAP and most of them via auto-titrating PAP with a range of 4–16 cmH2O. Following the GBP, in 31 patients (70.5%) OSA was improved, allowing PAP to be stopped (AHI

Introduction: In recent years, the prevalence of Obstructive Sleep Apnea (OSA) in the Indian population has increased. Despite this surge, the awareness of OSA in our population is low.Aims: To determine the predisposing risk factors and awareness of OSA in an unselected Indian population.Methods: An Internet-based questionnaire consisting of 14 questions pertaining to various facets of OSA was administered to 1006 subjects via several social media platforms. Given the difficulties in measuring neck circumference in an internet-based survey, a STOP-BAG score was calculated instead of a STOP-BANG score. Increased risk of OS...

This study was conducted among consecutive adults, who were admitted to the Department of Pulmonary Medicine, Marmara University, Istanbul between November 2015 and October 2018. Participants answered the questionnaires and underwent a sleep study with cardiorespiratory polygraphy. OSA was defined as an Apnoe-Hypopnoe-Index (AHI)≥15/h.In all, 1042 adults (334 women; 32.1%) were included. OSA was diagnosed in 589 (56.5%). In the OSA group, women were older (53.7±11.5 vs 47.8± 12.8 yrs; p

Conclusion and Discussion: Our study shows that the treatment by CPAP in obese patients with severe OSAHS doesn’t improve the function of the muscular and cardiorespiratory chain. In addition to CPAP, a pulmonary rehabilitation program training and weight reduction can help us in the care of those patients.

Conclusions:The differential results of heritability and familial aggregation of OSA in normal weight and overweight subgroups substantiated the recommendation of separating childhood OSA into normal weight and overweight subtypes. In the overweight subgroup, there may be obesity-independent components involved in the genetic variance of OAHI, although a significant proportion of the genetic variance is shared with obesity.Citation:Au CT, Zhang J, Cheung JYF, Chan KCC, Wing YK, Li AM. Familial aggregation and heritability of obstructive sleep apnea using children probands.J Clin Sleep Med. 2019;15(11):1561–1570.

This study demonstrated ultrasonography in predicting difficult laryngoscopy lacked utility. Ultrasound utilization as an efficacious means of difficult airway assessment requires further research with a larger sample size. Further studies using sonography on those patients with known difficult airways may provide data to determine if ultrasound has utility in predicting difficult laryngoscopy.

Conclusion: :OSA is not uncommon in asthma patients. Careful assessment of sleep related symptoms and demographic parameters of asthma patients are essential to suspect diagnosis of OSA. Additional factors like smoking, obesity, GERD and allergic rhinitis are important contributing factor for higher risk of OSA among asthma patients. Early diagnosis of OSA in asthma patients by polysomnography may have a clinical benefit in the management of both diseases. PMID: 31321930 [PubMed - in process]

Conclusions:Modeling neck circumference while allowing for differences by Mallampati class showed a nearly threefold increase in the risk of SDB with increasing neck circumference in women with Mallampati class 1.

Loud snoring ruins the lives of millions: the snorers’ as well as those who have to listen to it frequently. However, snoring isn’t just an annoyance. It can hint at a serious sleeping disorder: sleep apnea. Not only does the condition cause frustration in itself, but when looking at the comfort of it, its treatment could be compared to an attack of Aliens. How could digital health help patients who undergo sleep apnea treatment? Are there any ways to get rid of the Aliens? Almost 1 in 7 people have sleep apnea worldwide ‘Laugh and the world laughs with you, snore and you sleep alone’, that&rs...
