Hypopnea Syndrome

The syndrome of obstructive sleep apnea/hypopnea is a common disease which is caused by obstruction of the upper respiratory tract. This condition is characterized by repeated pauses in breathing during sleep. It is usually associated with a decrease in blood oxygen saturation. Primary risk factors of obstructive sleep apnea/hypopnoea syndrome — age, being a male and the family anamnesis. To the minor factors contributing to development of obstructive sleep apnea/hypopnoea syndrome, adiposity, abusing alcohol, the smoking, a habitual snore, day drowsiness.The researchers are interested in this problem due to the fact that obstructive sleep apnea/hypopnea syndrome is an adverse consequence of cardiovascular diseases and sudden death. Objective. Determine the prevalence of this disease in the outpatient medical practiceMaterial and methods. Out-patient cardio-respiratory monitoring. Results and discussion. High incidence of disease in outpatient patients.

Obstructive sleep apnea (OSA) is a common disorder which may need to be treated by the upper respiratory tract (URT) surgery. To increase the success rate of the URT surgery, it is crucial to understand the flow features in the URT models. In this work, the turbulent flow characteristics in four 3D anatomically accurate URT models reconstructed from two OSA subjects with successful and failed surgery are numerically studied by the large-eddy simulation (LES) and unsteady Reynolds-averaged Navier-Stokes (RANS). The features of velocity fields, pressure fields, and wall shear stress fields as well as the spectral analysis of wall shear stress between successful and failed surgery are explored. The results indicate that LES is capable of capturing flow patterns and flow oscillation and is effective for OSA surgery prediction. Even if the unsteady RANS can obtain the correct pressure drop across the airways, it may not be appropriate to be used for surgery prediction. Moreover, it is found that the quality of oscillating signal of wall shear stress is a key factor in surgery prediction. In a successful surgery, the wall shear stress oscillation is always strong, and the oscillating signal can perform a dominant frequency near 3~5 Hz, while in a failed surgery it does not show this clear intrinsic property. The results not only will gain new insights in the URT surgical planning but also will improve the prediction of surgical outcome for OSA patients.

Obstructive Sleep

Obstructive sleep apnea (OSA) is a common disease, with approximately 3–7% of men and 2–5% of women worldwide suffering from symptomatic OSA. If OSA is left untreated, hypoxia, microarousals and increased chemoreceptor stimulation can lead to complications like hypertension (HT). Continuous positive airway pressure (CPAP) is the most common treatment for OSA, and it works by generating airway patency, which will counteract the apnea or hypopnea. More than one billion people in the world suffer from HT, and the usual treatment is pharmacological with antihypertensive medication (AHM). The focus of this review will be to investigate whether the CPAP therapy for OSA affects HT.

Objective. The aim of this study was to compare the differences in thyroid hormone, intelligence, attention, and quality of life (QoL) of children with obstructive sleep apnea hypopnea syndrome (OSAHS) before and after endoscopic adenoidectomy.Method. A total of 35 OSAHS children (21 males and 14 females with a mean age of6.81±1.08years) were included in this study for analyzing the levels of thyroid hormone, intelligence, attention, and QoL. There were 22 children underwent endoscopic adenoidectomy with bilateral tonsillectomy (BT), while the other 13 children who underwent endoscopic adenoidectomy without bilateral tonsillectomy without BT.Results. Our results revealed no significant difference in serum free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) levels in OSAHS children before and after endoscopic adenoidectomy (allP>0.05). However, there were significant differences in full-scale intelligence quotient (FIQ) (92.45±5.88versus106.23±7.39,P<0.001), verbal intelligence quotient (VIQ) (94.17±15.01versus103.91±9.74,P=0.006), and performance intelligence quotient (PIQ) (94.12±11.04versus104.31±10.05,P=0.001), attention (98.48±8.74versus106.87±8.58,P<0.001), and total OSA-18 scores (87.62±17.15versus46.61±10.15,P<0.001) between before and after endoscopic adenoidectomy in OSAHS children.Conclusion. Our findings provided evidence that the intelligence, attention, and QoL of OSAHS children may be significantly improved after endoscopic adenoidectomy.
