Clinical efficacy and mechanism study of mid-frequency anti-snoring device in treating moderate obstructive sleep apnea-hypopnea syndrome

BACKGROUND Obstructive sleep apnea-hypopnea syndrome(OSAHS)is primarily caused by airway obstruction due to narrowing and blockage in the nasal and nasopha-ryngeal,oropharyngeal,soft palate,and tongue base areas.The mid-frequency anti-snoring device is a new technology based on sublingual nerve stimulation.Its principle is to improve the degree of oropharyngeal airway stenosis in OSAHS patients under mid-frequency wave stimulation.Nevertheless,there is a lack of clinical application and imaging evidence.METHODS We selected 50 patients diagnosed with moderate OSAHS in our hospital between July 2022 and August 2023.They underwent a 4-wk treatment regimen involving the mid-frequency anti-snoring device during nighttime sleep.Following the treatment,we monitored and assessed the sleep apnea quality of life index and Epworth Sleepiness Scale scores.Additionally,we performed computed tomo-graphy scans of the oropharynx in the awake state,during snoring,and while using the mid-frequency anti-snoring device.Cross-sectional area measurements in different states were taken at the narrowest airway point in the soft palate posterior and retrolingual areas.RESULTS Compared to pretreatment measurements,patients exhibited a significant reduction in the apnea-hypopnea index,the percentage of time with oxygen saturation below 90%,snoring frequency,and the duration of the most prolonged apnea event.The lowest oxygen saturation showed a notable increase,and both sleep apnea quality of life index and Epworth Sleepiness Scale scores improved.Oropharyngeal computed tomography scans revealed that in OSAHS patients cross-sectional areas of the oropharyngeal airway in the soft palate posterior area and retrolingual area decreased during snoring compared to the awake state.Conversely,during mid-frequency anti-snoring device treatment,these areas increased compared to snoring.CONCLUSION The mid-frequency anti-snoring device demonstrates the potential to enhance various sleep parameters in patients with moderate OSAHS,thereby improving their quality of life and reducing daytime sleepiness.These therapeutic effects are attributed to the device’s ability to ameliorate the narrowing of the oropharynx in OSAHS patients.

Obstructive sleep apnea-hypopnea syndrome immunological relationship

Obstructive sleep apnea-hypopnea syndrome(OSAHS)is a complex disorder cha-racterized by symptoms resulting from intermittent hypoxia and hypopnea,with research indicating a crucial role of immune system dysregulation and genetic variations in its pathogenesis.A recent Zhao et al study utilizes Mendelian ran-domization analysis to explore the causal relationship between immune cell characteristics and OSAHS.The study identifies specific lymphocyte subsets as-sociated with OSAHS,providing valuable insights into the disease's pathophy-siology and potential targets for therapeutic intervention.The findings underscore the significance of genetic and immunological factors in sleep disorders,offering a fresh perspective on OSAHS's complexities.Compared to existing literature,Zhao et al's study stands out for its focus on genetic markers and specific immune responses associated with OSAHS,expanding upon previous research primarily centered on systemic inflammation.In conclusion,the study represents a signi-ficant advancement in the field,shedding light on the causal role of immune cells in OSAHS and paving the way for future research and targeted treatments.

Intermittent hypoxia is involved in gut microbial dysbiosis in type 2 diabetes mellitus and obstructive sleep apnea-hypopnea syndrome

BACKGROUND Obstructive sleep apnea(OSA)-hypopnea syndrome(OSAHS)has been recognized as a comorbidity of type 2 diabetes mellitus(T2DM);more than half of T2DM patients suffer from OSAHS.Intermittent hypoxia(IH)plays an important role in metabolic diseases,such as obesity and OSAHS,through various mechanisms,including altering the gut microecological composition and function.Therefore,it is important to study the role of gut microbiota in T2DM patients with OSAHS,which has a high incidence and is prone to several complications.AIM To assess whether IH is involved in altering the fecal microbiome in T2DM patients with OSAHS.METHODS Seventy-eight participants were enrolled from Henan Province People’s Hospital and divided into healthy control(HC,n=26),T2DM(n=25),and T2DM+OSA(n=27)groups based on their conditions.The fecal bacterial DNA of the research participants was extracted and subjected to 16S ribosomal RNA sequencing.The clinical indices,such as insulin resistance index,homocysteine(HCY)concentration,and the concentrations of inflammatory factors in the peripheral blood,were assessed and recorded.RESULTS Group T2DM+OSA had the highest apnea-hypopnea index(AHI)(2.3 vs 3.7 vs 13.7),oxygen desaturation index(0.65 vs 2.2 vs 9.1),HCY concentration(9.6μmol/L vs 10.3μmol/L vs 13.81μmol/L)and C-reactive protein(CRP)concentrations(0.3 mg/L vs 1.43 mg/L vs 2.11 mg/L),and lowest mean oxygen saturation(97.05%vs 96.6%vs 94.7%)among the three groups.Twelve and fifteen key differences in amplicon sequence variants were identified when comparing group T2DM+OSA with groups T2DM and HC,respectively.We found progressively decreased levels of Faecalibacterium,Eubacterium,and Lachnospiraceae,and an increase in the level of Actinomyces,which strongly correlated with the HCY,CRP,fasting plasma glucose,and hemoglobin A1c concentrations,AHI,mean oxygen saturation,and insulin resistance index in group T2DM+OSA(P<0.05).CONCLUSION For T2DM patients with OSAHS,IH may be involved in selective alterations of the gut microbiota,which may affect the pathophysiological development of T2DM and DM-related complications.

Effect of motivational interviewing on postoperative weight control in patients with obstructive sleep apnea-hypopnea syndrome

BACKGROUND Obesity is an important factor to cause the obstructive sleep apnea-hypopnea syndrome(OSAHS).Higher body mass index(BMI)often results in more severe OSAHS.Currently,the common measures for controlling the weight mainly include diet control,increase exercise and so on.Motivational interviewing(MI)could explore the patient’s internal state and make the patient realize his/her ambivalence,resulting in the change in his/her behavior.This process emphasizes respecting the patient’s autonomy.AIM To evaluate the effect of MI on the weight control of patients with OSAHS.METHODS A randomized controlled study was conducted in 100 obese OSAHS patients undergoing surgical treatment at Shengjing Hospital of China Medical University.The patients were divided into an intervention group and a control group,with 50 cases each.The control group was given routine health education after the operation;in addition to the regular health education,the intervention group was given MI according to a predetermined plan.Obesity-related indicators,postoperative complications,and the sleep status of both groups were evaluated before and 6 mo after the intervention.RESULTS Patients in the intervention group had significantly improved body weight,BMI,and waist and neck circumferences compared with patients in the control group(P<0.05).Regarding complications at 6 mo after operation,the incidence of cough and reflux in patients in the intervention group was significantly lower than that in the control group(P<0.05).In addition,the Epworth Sleepiness Scale and Self-Rating Scale of Sleep scores of patients in the intervention group were significantly lower than those in the control group,and the sleep status of patients in the intervention group was improved(P<0.05).CONCLUSION MI intervention has a significant advantage over postoperative routine health education.It can greatly change the lifestyle,further control the postoperative weight,reduce the occurrence of complications,improve the quality of sleep,and improve long-term postoperative efficacy in OSAHS patients.

Relationship between obstructive sleep apnea-hypopnea syndrome(OSAHS)and liver fibrosis

Objective:The current study discusses the relationship between sleep apnea-hypopnea syn-drome(OSAHS)and liver fibrosis by determining the level of plasma hyaluronic acid(HA),pro-collagen III(PIII),collagen IV(IVC),and laminin(LN)in OSAHS patients and non-OSAHS patients with obesity and normal body weight.Methods:The patients who underwent polysomnographic(PSG)examinations in the outpatient and inpatient departments of our hospital between December 2010 and June 2013 were selected.The patients were divided into two groups based on the apnea-hypopnea index(AHI;OSAHS and non-OSAHS patients),and both groups were further divided based on obesity and normal body weight based on the body mass index(BMI).Sleep breathing indicators,including BMI,AHI,LSaO_(2),and MSaO_(2),were measured in all patients.All of the patients had their blood drawn on the morning after the day of the PSG examination,and the samples were sent to the biochemical laboratory of our hospital for determination of the levels of HA,PIII,IVC,and LN.Results:Among the obese and normoweight patients,the levels of HA,PIII,IVC,and LN in OSAHS patients were higher than the non-OSAHS patients(P value<0.05).Amongst the OSAHS and non-OSAHS patients,the levels of HA,PIII,IVC,and LN in the obese patients were also higher than the non-obese patients(P value<0.05).The levels of HA,PIII,IVC,and LN in the obese OSAHS patients were higher than the remaining three groups(P value<0.05).The levels of HA,PIII,IVC,and LN had positive correlations with the AHI and BMI(r=0.701,0.523,0.639,and 0.421,respectively,P<0.05;and r=0.565,0.441,0.475,and 0.401,respectively,P<0.05),and nega-tive correlations with the LSaO_(2) and MSaO_(2) in OSAHS patients(r=-0.432,-0.394,-0.403,and-0.267,respectively,P<0.05;and r=-0.591,-0.517,-0.533,and-0.484,respectively,P<0.05).Conclusion:The levels of plasma HA,PIII,IVC,and LN in OSAHS patients were related to OSAHS.OSAHS might lead to liver fibrosis.

Relation between Obstructive Sleep Apnea-Hypopnea Syndrome and Glaucoma in a Sub-Saharan African Population

Introduction: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a frequent pathology worldwide whose main mechanism is a complete or partial obstruction of the upper airway. 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. Methodology: 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. Results: 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). Conclusion: 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.
