However, CPAP compliance remains suboptimal, leading to alternative treatments like the Inspire implant, which stimulates the hypoglossal nerve to maintain airway patency. This case report discusses a 75-year-old male with OSA and CPAP intolerance, successfully treated with the Inspire implant. Postoperative imaging confirmed the proper placement of the device, and the patient reported significant improvements in symptoms. This case highlights the expected radiographic findings of the device.展开更多

Significant emphasis has been placed on obtaining blood pressure, body mass index, and placing importance on screening for signs and symptoms pointing towards cardiovascular disease. Symptoms related to sleep, or screening for sleep apnea has been overlooked by cardiac, diabetic, pulmonary and general medicine clinics despite recommendations for screening by several societies. In recent years, there is mounting data where obesity and obstructive sleep apnea sit at the epicenter and its control can lead to improvement and prevention of diabetes and cardiovascular complications. This editorial raises questions as to why obstructive sleep apnea screening should be included as yet another vital sign during patient initial inpatient or outpatient visit.展开更多

Studies on cognitive performance ...The present study aimed to investigate the efficacy of adenotonsillectomy(AT) for children with obstructive sleep apnea syndrome(OSAS) and the improvement of their cognitive function. Studies on cognitive performance of OSAS children treated with or without AT were identified by searching the Pubmed, EMBASE and Cochrane library. A meta-analysis was conducted to analyze the literature. The random-effects model was used to evaluate 11 eligible studies using an inverse-variance method. The neuropsychological test results of 4 cognitive domains(general intelligence, memory, attention-executive function and verbal ability) were obtained and analyzed. By comparison of cognitive function between OSAS children and healthy controls, the effect sizes of each domain were achieved as follows: general intelligence, –0.5(P<0.0001); memory, –0.18(P=0.02); attention-executive function, –0.21(P=0.002); and verbal ability, –0.48(P=0.0006). The effect sizes of general intelligence, memory, attention-executive function, and verbal ability after AT compared to baseline level were –0.37(P=0.008), –0.36(P=0.0005), –0.02(P=0.88), and –0.45(P=0.009), respectively. Comparing the cognitive ability between OSAS children after AT and healthy controls showed that the effect sizes were –0.54(P=0.0009), –0.24(P=0.12), –0.17(P=0.35), and –0.45(P=0.009) in general intelligence, memory, attention-executive function, and verbal ability, respectively. Our results confirmed that OSAS children performed worse than healthy children in terms of the 4 cognitive domains investigated. After 6–12 months of observation, significant improvement in attention-executive function and verbal ability were found in OSAS children treated with AT compared to their baseline level; restoration of attention-executive function and memory were observed in OSAS children after AT in comparison to healthy controls. Further rigorous randomized controlled trials should be conducted to obtain definitive conclusions.展开更多

文摘Obstructive sleep apnea(OSA)and coronary artery disease(CAD)frequently coexist,forming a bidirectional pathophysiological loop that amplifies cardiovascular risk.Intermittent hypoxemia in OSA patients promotes endothelial dysfunction,systemic inflammation,oxidative stress,and sympathetic activation,thereby accelerating atherogenesis,whereas myocardial ischemia and ventricular dysfunction in CAD patients can further destabilize upper-airway patency and exacerbate OSA.Continuous positive airway pressure(CPAP)is the standard therapy for OSA and reliably restores sleep architecture;however,large randomized trials have reported inconsistent effects on major adverse cardiovascular events,particularly in patients with established CAD.This mini review synthesizes contemporary data on CPAP across diverse OSA–CAD clinical scenarios,delineates patient phenotypes most likely to achieve cardiovascular benefit and identifies contexts in which CPAP provides limited protection.On the basis of these findings,we propose pragmatic recommendations for patient selection,adherence monitoring and optimization of CPAP therapy and highlight key research priorities,including extended follow-up,adherence-enhancing strategies and multimodal interventions.Clarifying the circumstances under which CPAP is cardioprotective will enable more precise management of patients with OSA,with or without concomitant CAD.

文摘Patients with suspected OSA were examined using PSG.They were divided into two groups based on the presence of nocturia.Nocturia was defined as a patient who needed to void at least once.Apneaehypopnea index(AHI)was employed to classify patients according to degrees of severity:AHI<5 events/h,5 events/hAHI<15 events/h,15 events/hAHI<30 events/h,and AHI30 events/h,defined as normal,mild OSA,moderate OSA,and severe OSA,respectively.Demographic variables,PSG parameters,International Prostate Symptom Scores(IPSSs),and quality of life scores due to urinary symptoms were analyzed.Results:In total 140 patients,114 patients had OSA(48 had mild OSA;34 had moderate OSA;and 32 had severe OSA)and 107 patients had nocturia.The total IPSS was significantly higher in nocturia patients in all groups except the group of severe OSA patients.With the increasing severity of OSA,more correlated factors related to nocturia were determined.In mild OSA patients,nocturia related to increased age(p=0.025),minimum arterial blood oxygenation saturation(p=0.046),and decreased AHI of non-rapid eye movement(p=0.047),AHI of total sleep time(p=0.010),and desaturation index(p=0.012).In moderate OSA patients,nocturia related to increased age(p<0.001),awake time(p=0.025),stage 1 sleep(p=0.033),and sleep latency(p=0.033),and decreased height(p=0.044),weight(p=0.025),and sleep efficiency(p=0.003).In severe OSA patients,nocturia related to increased weight(p=0.011),body mass index(p=0.009),awake time(p=0.008),stage 1 sleep(p=0.040),arousal number(p=0.030),arousal index(p=0.013),periodic limb movement number(p=0.013),and periodic limb movement index(p=0.004),and decreased baseline arterial blood oxygenation saturation(p=0.046).Conclusion:Our study revealed that there were more correlated factors related to nocturia with increasing severity of OSA.This study helps in clinical education and treatment for OSA patients with different severity.
文摘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.

文摘BACKGROUND Despite being one of the most prevalent sleep disorders,obstructive sleep apnea hypoventilation syndrome(OSAHS)has limited information on its immunologic foundation.The immunological underpinnings of certain major psychiatric diseases have been uncovered in recent years thanks to the extensive use of genome-wide association studies(GWAS)and genotyping techniques using highdensity genetic markers(e.g.,SNP or CNVs).But this tactic hasn't yet been applied to OSAHS.Using a Mendelian randomization analysis,we analyzed the causal link between immune cells and the illness in order to comprehend the immunological bases of OSAHS.AIM To investigate the immune cells'association with OSAHS via genetic methods,guiding future clinical research.METHODS A comprehensive two-sample mendelian randomization study was conducted to investigate the causal relationship between immune cell characteristics and OSAHS.Summary statistics for each immune cell feature were obtained from the GWAS catalog.Information on 731 immune cell properties,such as morphologic parameters,median fluorescence intensity,absolute cellular,and relative cellular,was compiled using publicly available genetic databases.The results'robustness,heterogeneity,and horizontal pleiotropy were confirmed using extensive sensitivity examination.RESULTS Following false discovery rate(FDR)correction,no statistically significant effect of OSAHS on immunophenotypes was observed.However,two lymphocyte subsets were found to have a significant association with the risk of OSAHS:Basophil%CD33dim HLA DR-CD66b-(OR=1.03,95%CI=1.01-1.03,P<0.001);CD38 on IgD+CD24-B cell(OR=1.04,95%CI=1.02-1.04,P=0.019).CONCLUSION This study shows a strong link between immune cells and OSAHS through a gene approach,thus offering direction for potential future medical research.
文摘In this review article,we explore the interplay between obstructive sleep apnea(OSA)and type 2 diabetes mellitus(T2DM),highlighting a significant yet often overlooked comorbidity.We delve into the pathophysiological links between OSA and diabetes,specifically how OSA exacerbates insulin resistance and disrupts glucose metabolism.The research examines the prevalence of OSA in diabetic patients and its role in worsening diabetes-related complications.Emphasizing the importance of comprehensive management,including weight control and positive airway pressure therapy,the study advocates integrated approaches to improve outcomes for patients with T2DM and OSA.This review underscores the necessity of recognizing and addressing OSA in diabetes care to ensure more effective treatment and better patient outcomes.

文摘Background:Obstructive sleep apnea(OSA)is highly common in patients with coronary artery disease(CAD)and it is a strong predictor of subsequent cardiovascular events.However,whether treatment with continuous positive airway pressure(CPAP)can decrease this risk remains controversial.Methods:PubMed,EMBASE,the Cochrane Library,and ClinicalTrials.gov were systematically searched to identify randomized clinical trials reporting cardiovascular events from database inception to February 12,2022.Results:Four trials with 3043 participants were included.The median follow-up duration ranged from 3 to 4.75 years.Compared with usual care alone,CPAP was not associated with decreased MACCE risk(RR 0.96,95%CI 0.77–1.21,P=0.75),and the results were consistent regardless of CPAP adherence(≥4 hours/night vs.<4 hours/night,RR 0.48,95%CI 0.20–1.16).Similarly,no significant differences were observed between groups in the risks of all-cause death(RR 0.81,95%CI 0.52–1.26),cardiovascular death(RR 0.70,95%CI 0.36–1.33),myocardial infarction(RR 1.08,95%CI 0.73–1.60),revascularization(RR 1.03,95%CI 0.77–1.38),and cerebrovascular events(RR 0.77,95%CI 0.23–2.61).Conclusion:Existing evidence does not support an association between CPAP treatment and decreased risk of recur-rent cardiovascular events in patients with CAD and OSA,regardless of adherence to CPAP.

文摘D-transposition of the great arteries(d-TGA)is surgically repaired with the arterial switch operation(ASO)with excellent results,however short and long-term morbidities still develop including neurocognitive delay.Clinically significant central sleep apnea is uncommon in non-premature infants,but when present indicates immature autonomic control of respiration likely due to a neurologic disorder.We report the unanticipatedfinding of central sleep apnea in four-term neonates with d-TGA after uncomplicated ASO,with the short-term complication of delayed hospital discharge and long-term concerns regarding this early marker of brain immaturity and its hindrance to normal development.Within this report,we will review each patient’s clinical course and then examine the literature on pediatric central sleep apnea,neurodevelopmental outcomes after ASO,and the important overlap of these entities in the care of patients going forward.
文摘Obstructive sleep apnea(OSA)is a rapidly increasing global concern.If it remains untreated,it can lead to cardiovascular,metabolic,and psychiatric complications and may result in premature death.The efficient and effective management of OSA can have a beneficial effect and help reduce the financial burden on the health sector.There has been constant development in OSA management,and numerous options are available.The mainstay of therapy is still the conventional measures and behavioral modifications.However,in cases of failure of these modalities,surgical therapy is the only option.Numerous studies have shown that proper management of OSA has beneficial effects with good long-term outcomes.
文摘Obstructive sleep apnea(OSA)is often a lifestyle disease associated with obesity,which is rapidly evolving as a major health concern with diverse multisystemic implications.To prevent and mitigate its adverse effects and reduce its burden on society,its aetiopathogeneses must be precisely understood.Numerous studies focusing on the range of diverse anatomic,functional,and lifestyle factors have already been carried out to determine the possible contributory roles of these factors in OSA.Recently,evidence to validate the role of inflammatory pathways and immune mechanisms in the aetiopathogeneses of OSA is being developed.This allows for further research and translation of such knowledge for targeted therapeutic and preventive interventions in patients with or who are at risk of developing OSA.
文摘BACKGROUND Obstructive sleep apnea hypoventilation syndrome(OSAHS)in children is a sleep respiratory disorder characterized by a series of pathophysiologic changes.Statistics in recent years have demonstrated an increasing yearly incidence.AIM To investigate the risk factors for OSAHS in children and propose appropriate management measures.METHODS This study had a case–control study design.Altogether,85 children with OSAHS comprised the case group,and healthy children of the same age and sex were matched at 1:1 as the control group.Basic information,including age,sex,height,weight and family history,and medical history data of all study participants were collected.Polysomnography was used to detect at least 8 h of nocturnal sleep.All participants were clinically examined for the presence of adenoids,enlarged tonsils,sinusitis,and rhinitis.RESULTS The analysis of variance revealed that the case group had a higher proportion of factors such as adenoid grading,tonsil indexing,sinusitis,and rhinitis than the control group.CONCLUSION A regression model was established,and glandular pattern grading,tonsil indexing,sinusitis,and pharyngitis were identified as independent risk factors affecting OSAHS development.
文摘Depression and metabolic syndrome could exacerbate the risks of the other,leading to a series of severe coexisting conditions.One notable comorbidity that must be mentioned is obstructive sleep apnea(OSA).Current studies suggested that depression increases susceptibility to OSA.As the prevalence of depression rises,it becomes critical to prevent and manage its complications or comorbidities,including OSA.Predictive models,non-invasive electroencephalogram moni-toring,genetic research,and other promising technologies are being applied to the prevention,diagnosis,and personalized treatment of depression and OSA.
文摘Obstructive sleep apnea (OSA) is a prevalent condition marked by repetitive pharyngeal collapse during sleep, often treated with continuous positive airway pressure (CPAP). However, CPAP compliance remains suboptimal, leading to alternative treatments like the Inspire implant, which stimulates the hypoglossal nerve to maintain airway patency. This case report discusses a 75-year-old male with OSA and CPAP intolerance, successfully treated with the Inspire implant. Postoperative imaging confirmed the proper placement of the device, and the patient reported significant improvements in symptoms. This case highlights the expected radiographic findings of the device.
文摘Aim:To study the relationship between NLRP3(nucleotide oligomerization domain[NOD]-,leucine-rich repeats[LRR]-,and pyrin domain-containing protein 3)inflammasome and its downstream inflammatory factors in obstructive sleep apnea(OSA)patients with carotid atherosclerosis(CAS)under cigarette exposure,further exploring the risk factors of CAS in OSA patients.Methods:A total of 109 adult males who underwent polysomnography and carotid artery ultrasonography in our hospital from October 2019 to December 2021 were selected.According to the detection results,they were divided into the OSA group,the CAS group,and the OSA combined CAS group;additionally,29 healthy subjects who underwent a physical examination were also included.According to whether they were smoking,the groups were further divided into smoking and non-smoking groups.The age,body mass index(BMI),blood pressure,apnea-hypopnea index(AHI),lowest blood oxygen saturation(LSaO2),carotid intima-media thickness(CIMT),levels of blood sugar,blood low-density lipoprotein cholesterol(LDLc),and serum NLRP3,interleukin-1β(IL-1β),and interleukin-18(IL-18)of all subjects were recorded.Results:The OSA combined CAS group had higher LDLc levels and AHI and lower LSaO2 than the OSA group and CAS group.The levels of serum NLRP3,IL-1β,and IL-18 in the OSA group were higher than those in the normal control group(P<0.05);and those in the OSA combined CAS group were higher than the OSA group and CAS group(P<0.05),regardless of cigarette exposure.Considering cigarette exposure,serum NLRP3,IL-1β,and IL-18 levels were higher in the OSA,CAS,and OSA combined CAS smoking groups than those in the non-smoking group(P<0.05).Under cigarette exposure,AHI,LDLc,NLRP3,IL-1β,and IL-18 were significantly positively correlated(P<0.05),and LSaO2 was negatively correlated with CAS in OSA(P<0.05).AHI,LSaO2,LDLc,NLRP3,and IL-1βare the risk factors for OSA combined with CAS.Conclusion:LSaO2,AHI,LDLc,NLRP3,and IL-1βare the important risk factors for OSA combined with CAS under cigarette exposure,and their levels can be used to predict the occurrence of CAS in OSA.

文摘Objective:This study was aimed at investigating the effects of the neutrophil-to-lymphocyte ratio(NLR)on the long-term prognosis of patients with acute coronary syndrome(ACS)and obstructive sleep apnea(OSA).Methods:This prospective study enrolled patients with ACS and OSA at Anzhen Hospital between June 2015 and January 2020.OSA was defined by an apnea-hypopnea index≥15 events·h-1.Baseline NLR was classified as high or low,according to the median.The primary endpoint was major adverse cardiovascular events(MACE),comprising cardiovascular death,recurrent myocardial infarction,stroke,and ischemia-driven revascularization.Results:Atotal of 1011 patients withACS and OSAwere enrolled,506 of whom were in the high NLR(≥2.54)group.No significant differences in sleep monitoring indicators were observed.During a median follow-up of 2.8(1.4,3.6)years,a non-linear correlation between NLR and the incident risk of MACE was observed.After adjustment for clini-cally relevant confounders,a high NLR was independently associated with elevated MACE risk(adjusted HR=1.45,95%CI:1.02–2.06,P=0.040).Conclusions:In patients with ACS and OSA,a high NLR was associated with poorer clinical outcomes during long-term follow-up.Trial registration:ClinicalTrials.gov;Number:NCT03362385;URL:www.clinicaltrials.gov.
文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)is an emerging liver disease and currently the most common cause of incidental abnormal liver tests.The pathogenesis of NAFLD is multifactorial and many mechanisms that cause fatty liver infiltration,inflammation,oxidative stress and progressive fibrosis have been proposed.Obstructive sleep apnea(OSA)may be linked with the pathogenesis and the severity of NAFLD.AIM To study the association between NAFLD and OSA considering also the efficacy of continuous positive airway pressure(CPAP)treatment.METHODS A Pub Med search was conducted using the terms"non-alcoholic fatty liver disease AND(obstructive sleep apnea OR obstructive sleep disorders OR sleep apnea)".Research was limited to title/abstract of articles published in English in the last 5 years;animal and child studies,case reports,commentaries,letters,editorials and meeting abstracts were not considered.Data were extracted on a standardized data collection table which included:First author,publication year,country,study design,number of patients involved,diagnosis and severity of OSA,diagnosis of NAFLD,patient characteristics,results of the study.RESULTSIn total,132 articles were initially retrieved on Pub Med search and 77 in the last five years.After removal of irrelevant studies,13 articles were included in the qualitative analysis.There was a total of 2753 participants across all the studies with a mean age between 42 and 58 years.The proportion of males ranged from21%to 87.9%and the mean body mass index ranged from 24.0 to 49.9 kg/m2.The results of this review showed an increased prevalence of NAFLD in patients with diagnosis of OSA,even in the absence of coexisting comorbidities such as obesity or metabolic syndrome.Furthermore,the severity of NAFLD is associated with the increase in OSA severity.Effective CPAP treatment,although not always decisive,may stabilize or slow NAFLD progression with benefits on metabolic and cardiovascular functions.CONCLUSION In NAFLD patients,although asymptomatic,it is recommended to systematically perform polysomnography in order to early and better treat them before the development of potentially life threatening systemic dysfunctions.
文摘Obesity, sleep apnea, diabetes and cardiovascular diseases are some of the most common diseases encountered by the worldwide population, with high social and economic burdens. Significant emphasis has been placed on obtaining blood pressure, body mass index, and placing importance on screening for signs and symptoms pointing towards cardiovascular disease. Symptoms related to sleep, or screening for sleep apnea has been overlooked by cardiac, diabetic, pulmonary and general medicine clinics despite recommendations for screening by several societies. In recent years, there is mounting data where obesity and obstructive sleep apnea sit at the epicenter and its control can lead to improvement and prevention of diabetes and cardiovascular complications. This editorial raises questions as to why obstructive sleep apnea screening should be included as yet another vital sign during patient initial inpatient or outpatient visit.

文摘The present study aimed to investigate the efficacy of adenotonsillectomy(AT) for children with obstructive sleep apnea syndrome(OSAS) and the improvement of their cognitive function. Studies on cognitive performance of OSAS children treated with or without AT were identified by searching the Pubmed, EMBASE and Cochrane library. A meta-analysis was conducted to analyze the literature. The random-effects model was used to evaluate 11 eligible studies using an inverse-variance method. The neuropsychological test results of 4 cognitive domains(general intelligence, memory, attention-executive function and verbal ability) were obtained and analyzed. By comparison of cognitive function between OSAS children and healthy controls, the effect sizes of each domain were achieved as follows: general intelligence, –0.5(P<0.0001); memory, –0.18(P=0.02); attention-executive function, –0.21(P=0.002); and verbal ability, –0.48(P=0.0006). The effect sizes of general intelligence, memory, attention-executive function, and verbal ability after AT compared to baseline level were –0.37(P=0.008), –0.36(P=0.0005), –0.02(P=0.88), and –0.45(P=0.009), respectively. Comparing the cognitive ability between OSAS children after AT and healthy controls showed that the effect sizes were –0.54(P=0.0009), –0.24(P=0.12), –0.17(P=0.35), and –0.45(P=0.009) in general intelligence, memory, attention-executive function, and verbal ability, respectively. Our results confirmed that OSAS children performed worse than healthy children in terms of the 4 cognitive domains investigated. After 6–12 months of observation, significant improvement in attention-executive function and verbal ability were found in OSAS children treated with AT compared to their baseline level; restoration of attention-executive function and memory were observed in OSAS children after AT in comparison to healthy controls. Further rigorous randomized controlled trials should be conducted to obtain definitive conclusions.
