One of the pathophysiological mechanisms described in primary open-angle glaucoma is that hypoxia in the optic nerve progressively destroys the retinal cells leading to the onset and/or aggravation of glaucoma. The aim of the study was to evaluate the risk of OSA in patients with primary open-angle glaucoma. <strong>Methodology:</strong> An analytical study was conducted from January to May 2020 at the UHC. After obtaining ethical clearance, 112 patients including 50 glaucoma patients (44.64%) and 62 in the control group were enrolled. Sociodemographic and clinical data were collected from the medical records of the participants, with or without glaucoma, and a questionnaire was administered and a clinical examination performed. The STOP BANG score was used to determine the risk level of OSAHS. Statistical analyses were performed using Epi Info version 7.2. <strong>Results:</strong> A female predominance was found (60%) in the glaucoma group with a mean age of 55 ± 17 years against 49 ± 18 years in the control group. The high risk of OSAHS was more associated with glaucoma patients. In glaucoma patients, an association was found between high risk of OSAHS and snoring (OR = [1.43 - 849.53];p = 0.029) as well as insomnia (OR = [1.36 - 482.86];p = 0.030). <strong>Conclusion:</strong> High risk of OSAHS was found in participants with chronic open-angle glaucoma. Signs of OSAHS should be sought in chronic open-angle glaucoma as it may be a factor in its progression.展开更多

Meanwhile the correlation between the concentration of VEGF and parameters of polysomnography （PSG） was examined. Our results showed that the concentrations of VEGF were significantly higher in OSAHS patients with severe hypoxia （536.8±334.7 pg/mL） than in those with mild hypoxia （329.2±174.7 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. The concentrations of VEGF were also significantly higher in OSAHS patients with hypertension （484.5±261.4 pg/mL） than in those without hypertension （311.0±158.4 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. There was a positive correlation between the concentration of VEGF and the apnea hypopnea index （AHI） （r=0.34, P〈0.05）. It is concluded that the concentration of the serum VEGF is positively related to the severity of OSAHS. The elevated serum VEGF level may be involved in the pathogenesis of the complications of obstructive sleep apnea hypopnea syndrome.展开更多

Sociodemographic and clinical data were collected from the medical records of the participants, with or without glaucoma, and a questionnaire was administered and a clinical examination performed. The STOP BANG score was used to determine the risk level of OSAHS. Statistical analyses were performed using Epi Info version 7.2. <strong>Results:</strong> A female predominance was found (60%) in the glaucoma group with a mean age of 55 ± 17 years against 49 ± 18 years in the control group. The high risk of OSAHS was more associated with glaucoma patients. In glaucoma patients, an association was found between high risk of OSAHS and snoring (OR = [1.43 - 849.53];p = 0.029) as well as insomnia (OR = [1.36 - 482.86];p = 0.030). <strong>Conclusion:</strong> High risk of OSAHS was found in participants with chronic open-angle glaucoma. Signs of OSAHS should be sought in chronic open-angle glaucoma as it may be a factor in its progression.
文摘Objective:To evaluate the characteristics of glucolipid metabolism as well as atherosclerosis in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) combined with cerebral infarction.Methods:Patients who were treated in the hospital due to acute cerebral infarction between March 2015 and February 2018 were selected, and according to the combination of OSAHS, the 300 patients with cerebral infarction were divided into the cerebral infarction group A who were combined with OSAHS and the cerebral infarction group B who were not combined with OSAHS;the 100 cases of healthy volunteers who underwent physical examination in our hospital during the same period were selected as the control group. The contents of glucolipid metabolism indexes, cytokines and plaque hydrolysis molecules in serum were determined.Results: Serum F-Ins, TC, LDL-C, VE-cadherin, YKL-40, FKN, M-CSF, MCP-1, MMP9, Caspase-3, ICTP and VCAM-1 levels of cerebral infarction group A and cerebral infarction group B were significantly higher than those of control group whereas HDL-C levels were significantly lower than that of control group;serum F-Ins, TC, LDL-C, VE-cadherin, YKL-40, FKN, M-CSF, MCP-1, MMP9, Caspase-3, ICTP and VCAM-1 levels of cerebral infarction group A were significantly higher than those of cerebral infarction group B whereas HDL-C level was significantly lower than that of cerebral infarction group B.Conclusion: There are more significant glucolipid metabolism disorder and worse plaque stability in patients with OSAHS combined with cerebral infarction.
文摘The main purpose of this study was to assess the reliability and validity of the simplified Chinese STOP-BANG Questionnaire(SBQ)as a diagnosing and screening tool for obstructive sleep apnea hypopnea syndrome(OSAHS).Two hundred and ten patients with suspected OSAHS were recruited in this study.The simplified Chinese SBQ was completed twice before and after polysomnography(PSG)monitoring.SPSS 20.0 was used to analyze the test-retest reliability,discriminant validity,comparative validity and predictive validity of the SBQ.Fourteen patients were excluded on account of fragmentary data,and valid 196 were divided into four groups:non-OSAHS group(n=28,14.29%),mild OSAHS group(n=28,14.29%),moderate OSAHS group(n=31,15.81%)and severe OSAHS group(n=109,55.61%).The test-retest coefficient tor the first four items was 0.810,0.679,0.775,0.963 respectively and the total score of the STOP questionnaire was 0.854.The analysis of discriminant validity revealed that there were significant differences among four groups in the total score of the SBQ and scores of item 1,3,7 and 8,which were also validated between patients with normal blood oxygen saturation and different degrees of hypoxemia.The SBQ evaluation showed low consistency with diagnostic gold standard PSG(k=0.3O3,P<0.05).When taking apnea hypopnea index(AHI)≥5/h,≥15/h and≥30/h as cut-offs to evaluate the SBQ predictive value,the areas under ROC curve were 0.77,0.81 and 0.78,the sensitivity was 90.48%,93.57%and 93.33%,and corresponding negative predictive values were 40.74%,66.67%and 85.19%,respectively.It was suggested that the simplified Chinese version of SBQ had good reliability,and could distinguish the severity of OSAHS.Despite its limited diagnostic accuracy,the SBQ can be considered as an ideal tool for screening OSAHS with superior predictive validity.
文摘To explore the relationship between the serum vascular endothelial growth factor （VEGF） level and the severity of obstructive sleep apnea hypopnea syndrome （OSAHS）, the concentrations of serum VEGF in 40 OSAHS patients and 9 healthy controls were measured by using ELISA method. Meanwhile the correlation between the concentration of VEGF and parameters of polysomnography （PSG） was examined. Our results showed that the concentrations of VEGF were significantly higher in OSAHS patients with severe hypoxia （536.8±334.7 pg/mL） than in those with mild hypoxia （329.2±174.7 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. The concentrations of VEGF were also significantly higher in OSAHS patients with hypertension （484.5±261.4 pg/mL） than in those without hypertension （311.0±158.4 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. There was a positive correlation between the concentration of VEGF and the apnea hypopnea index （AHI） （r=0.34, P〈0.05）. It is concluded that the concentration of the serum VEGF is positively related to the severity of OSAHS. The elevated serum VEGF level may be involved in the pathogenesis of the complications of obstructive sleep apnea hypopnea syndrome.
文摘BACKGROUND Carotid body tumor(CBT)is a chemoreceptor tumor located in the carotid body,accounting for approximately 0.22%of head and neck tumors.Surgery is the main treatment method for the disease.CASE SUMMARY We reviewed the diagnosis and treatment of one patient who had postoperative secondary aggravation of obstructive sleep apnea–hypopnea syndrome(OSAHS)and hypoxia after surgical resection of bilateral CBTs.This patient was admitted,and relevant laboratory and imaging examinations,and polysomnography(PSG)were performed.After the definitive diagnosis,continuous positive airway pressure(CPAP)treatment was given,which achieved good efficacy.CONCLUSION This case suggested that aggravation of OSAHS and hypoxemia is possibly caused by the postoperative complications after bilateral CBTs,and diagnosis by PSG and CPAP treatment are helpful for this patient.

文摘tObstructive sleep apnea-hypopnea syndrome(OSAHS)significantly impairs children's growth and cognition.This study aims to elucidate the pathophysiological mechanisms underlying OSAHS in children,with a particular focus on the alterations in cortical information interaction during respiratory events.We analyzed sleep electroencephalography before,during,and after events,utilizing Symbolic Transfer Entropy(STE)for brain network construction and information flow assessment.The results showed a significant increase in STE after events in specific frequency bands during N2 and rapid eye movement(REM)stages,along with increased STE during N3 stage events.Moreover,a noteworthy rise in the information flow imbalance within and between hemispheres was found after events,displaying unique patterns in central sleep apnea and hypopnea.Importantly,some of these alterations were correlated with symptom severity.These findings highlight significant changes in brain region coordination and communication during respiratory events,offering novel insights into OSAHS pathophysiology in children.
