Research progress on the diagnosis and treatment of pediatric malocclusion combined with obstructive sleep apnea-hypopnea syndrome / 口腔疾病防治

@#Pediatric malocclusion is common in dentistry. Some children with malocclusion combined with obstructive sleep apnea-hypopnea syndrome (OSAHS) often fail to receive appropriate treatment due to a lack of multidisciplinary diagnosis and treatment. It can cause abnormal ventilation during sleep, affecting the central nervous system and cardiovascular development and even causing neurological and behavioral problems. Pediatric OSAHS is caused by the narrowing of the upper respiratory tract, characterized by specific facial bone characteristics and neuromuscular factors and correlated with malocclusion. Due to its diverse clinical manifestations and etiology, the diagnosis and treatment of pediatric OSAHS require an interdisciplinary, personalized, and specialized approach. Questionnaires and physical examinations can be used for preliminary screening. Moreover, children's stomatology and otorhinolaryngology examinations are the basis for disease diagnosis. Polysomnography (PSG) is currently the direct diagnostic method. There are various treatment methods for OSAHS in children, and for OSAHS caused by adenoid tonsil hypertrophy, adenoidectomy and tonsillectomy are the main treatments. Othodontic treatment including mandibular advancement and rapid maxillary expansion et al is also effective for OSAHS in children with malocclusion. Currently, there is limited research on the correlation between childhood malocclusion and OSAHS, and multidisciplinary combination therapy may improve the cure rate, but there is a lack of sufficient evidence. In the future, the pathogenesis of OSAHS should be further elucidated, and research on multidisciplinary combination therapy should be promoted to achieve early intervention and treatment for potential and existing patients.

Study on Syndrome Research of Ischemic Stroke Combined with Obstructive Sleep Apnea-hypopnea Syndrome Based on Implicit Structure Method / 中国实验方剂学杂志

ObjectiveTo explore the common syndrome elements of cerebral ischemic stroke （CIS） complicated with obstructive sleep apnea-hypopnea syndrome （OSAHS）， reveal the characteristics of traditional Chinese medicine （TCM） syndromes of the disease， clarify the syndrome differentiation and syndrome types， provide evidence for clinical syndrome differentiation， and provide reference for establishing the TCM syndrome type standards of CIS complicated with OSAHS. MethodThe clinical information form of CIS complicated with OSAHS formulated by the research group was used for syndrome survey， and the four-examination information of 300 patients with CIS complicated with OSAHS was collected. The four-examination information of patients was analyzed by latent structure method and comprehensive cluster analysis， and the common syndrome elements of CIS complicated with OSAHS were extracted by combining the TCM basic theory and clinical experience. On this basis， the characteristics of TCM syndromes and the syndrome types in line with reality were summarized. ResultThe top five syndrome elements in patients with CIS and OSAHS are sleep snoring， open mouth breathing， physical obesity， night awakening and dizziness. The top five tongue and pulse manifestations are enlarged tongue， slippery pulse， slippery coating， thick and white coating and purple tongue. The disease locations are the lung， spleen， stomach， kidney， liver and brain. The nature of disease includes deficiency， depression， blood stasis， phlegm， dampness and fire. The clinical syndrome types include the syndrome of stagnation of phlegm and dampness， syndrome of phlegm-dampness blocking the mind， syndrome of spleen deficiency with dampness， syndrome of Yin deficiency leading to fire hyperactivity， syndrome of Qi depression blocking collaterals， syndrome of liver depression and blood stasis， syndrome of Qi deficiency with dampness， and syndrome of Yang deficiency induced water retention. ConclusionIn addition to the common phlegm-， dampness- and blood stasis-related syndromes in patients with CIS and OSAHS， there are also depression- and deficiency-related syndromes. The main etiology and pathogenesis is the disturbance of Qi movement. In clinical practice， attention should be paid to the specific situation of individual patients to differentiate between deficiency and excess， and the treatment should be performed by the method of soothing and reinforcing， or unblocking and clearing， or both.

Exploring acupuncture treatment strategies for snoring based on meridian theory / 中国针灸

Starting from the perspective of meridian theory, this article briefly analyzes the meridian pathophysiology of snoring and the relationship between snoring and meridian theory. It proposes that acupuncture treatment for snoring should focus on regulating qi from the shaoyang meridians, harmonizing the spirit by the governor vessel, resolving phlegm through the three yang meridians, and harmonizing qi and blood from the yangming meridians. Additionally, attention is placed on both the root cause and the symptoms, the theory of "four seas". The ultimate goal is to promote the flow of meridian and qi-blood, improve symptoms such as nighttime snoring, poor sleep quality, and daytime sleepiness, and achieve the desired outcome of stopping snoring and ensuring restful sleep.

Clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness" / 中国针灸

This study summarizes the clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness". According to the pathological characteristics of qi stagnation and blood stasis, phlegm dampness and internal obstruction in snoring patients, combined with the etiology, pathogenesis and location of the disease, the innovative viewpoint of "disharmony qi leads to restlessness" is proposed. It is believed that the key to snoring treatment lies in "regulating qi ". In clinical practice, acupuncture can directly regulate the qi of the disease's location, regulate the qi of the organs and viscera, and regulate the qi of the meridians to achieve overall regulation of the body's internal and external qi, smooth circulation of qi and blood, and ultimately achieve the therapeutic goal of harmonizing qi, stopping snoring, and improving sleep quality.

Efficacy of magnetic traction hyoid suspension surgery in the animal model of OSAHS / 西安交通大学学报(医学版)

【Objective】 To explore the effectiveness of creating the obstructive sleep apnea hypopnea syndrome (OSAHS) animal model of glossocoma using the botulinum toxin type A in white rabbits, and to explore the effectiveness and safety of magnetic traction hyoid suspension operation in the OSAHS animal model of glossocoma. 【Methods】 A total of 12 adult male experimental white rabbits were randomly divided into two groups. The animals in the experimental group were injected with 0.4 mL (10 U) of botulinum toxin type A in the genioglossus muscle to construct the OSAHS animal model of glossocoma. The animals in the control group were injected with 0.4 mL of normal saline. We designed and 3D printed a polyacrylate shell that could be loaded with inner and outer neodymium iron boron (NdFeB) magnets. After the modeling, a polyacrylate shell with the inner magnet device was fixed on the hyoid bone of the animals in the experimental group. All animals in the experimental group wore the polyacrylate orthotic neck brace containing the outer magnet 10 days after the operation. The arterial blood oxygen detector was used to record the oxygen saturation (SaO2) of the femoral artery, and multi-slice CT plain scan was used to measure the diameter of the narrowest part of the upper airway. 【Results】 The animals in the experimental group gradually showed decreased activity, labored breathing, blue lips and ear margins and other manifestations of hypoxemia 5 days after intramuscular injection of botulinum toxin type A in the genioglossus, and their body weight dropped from (3.72±0.21)kg to (3.40±0.20)kg, the average SaO2 of the femoral artery decreased from (93.84±5.14)% to (84.00±3.35)%, and the diameter of the narrowest part of the upper airway decreased from (4.83±0.47)mm to (3.52±0.83)mm (P<0.05). In the control group, the animals’ weight, the average SaO2 of the femoral artery, and the diameter of the narrowest part of the upper airway did not significantly change before and after injection of normal saline into the genioglossus muscle (P>0.05). The animals in the experimental group completed the magnetic traction hyoid suspension surgery. After wearing the orthotic neck brace containing an external magnet for hyoid magnetic traction, the food intake and activity of the animals in the experimental group increased, the color of the lips changed from purple to pink, the SaO2 of the femoral artery increased significantly to (90.44±5.95)%, and the diameter of the narrowest part of the upper airway increased significantly to (4.42±0.15)mm (P<0.05). 【Conclusion】 The genioglossus muscle injection of botulinum toxin type A in white rabbits could successfully establish the OSAHS animal model of glossocoma. Magnetic traction hyoid suspension surgery in the treatment of OSAHS animal model could effectively correct the upper airway stenosis related symptoms and hypoxemia caused by glossocoma.

Estudo do nível de conhecimento e interesse do cirurgião dentista no diagnóstico e tratamento da síndrome da apnéia/hipopnéia obstrutiva do sono (SAHOS) / Study of the level of knowledge and interest of the dental surgeon in the diagnosis and treatment of obstructive sleep apnea/hypopnea syndrome (OSAHS)

Atualmente, o tratamento do ronco primário e da Síndrome da Apnéia/Hipopnéia Obstrutiva do Sono (SAHOS)1 através de aparelhos intra-orais (AIO) tem recebido a atenção dos pesquisadores pela comprovada eficácia destes dispositivos. Os aparelhos mais indicados são os reposicionadores de mandíbula que promovem um avanço mandibular, afastando os tecidos da orofaringe superior, o que evita a obstrução parcial ou total da área. Sua indicação é para casos de ronco primário e apnéias leves e moderadas2, no entanto é necessário que os candidatos apresentem número de dentes suficientes com saúde periodontal para a ancoragem do aparelho. Por ser uma doença de consequências sistêmicas graves, o tratamento da SAHOS é em sua essência de responsabilidade do médico especialista na área, porém o cirurgião dentista deve ter conhecimento para diagnosticar e tratar, quando o AIO for a opção terapêutica. A interpretação da polissonografia, exame que diagnostica e conduz para a escolha correta do tratamento, e dos dados cefalométricos são os principais quesitos ao Cirurgião Dentista que se propõe a tratar portadores da SAHOS. Nesse trabalho foi elaborado um questionário e aplicado aos cirurgiões dentistas de três diferentes cidades do Estado de São Paulo para que fosse possível avaliar o conhecimento desses profissionais a respeito do diagnóstico e tratamento da SAHOS. 70 Cirurgiões Dentistas foram entrevistados e os resultados mostraram que 70% destes têm interesse em trabalhar com os AIOs. Esse grupo se relacionou estatisticamente significante com aqueles que afirmaram já terem sido alguma vez questionado por algum paciente a respeito desse tratamento. Quanto à criação de uma especialidade para essa área, os profissionais da área de prótese e implante se mostraram mais interessados. E, do número total de entrevistados, apenas 25% já tiveram contato com esse tipo de aparelho, mas não conhece o protocolo de atendimento para o tratamento desses pacientes(AU)

Currently, the treatment of primary snoring and Obstructive Sleep Apnea/Hypopnea Syndrome (OSAHS)1 through intraoral appliances (OA) has received the attention of researchers due to the proven effectiveness of these devices. The most suitable devices are jaw repositioning devices that promote mandibular advancement, moving the tissues away from the upper oropharynx, which prevents partial or total obstruction of the area. Its indication is for cases of primary snoring and mild to moderate apnea2, however it is necessary that candidates have a sufficient number of teeth with periodontal health to anchor the appliance. As it is a disease with serious systemic consequences, the treatment of OSAHS is, in essence, the responsibility of the specialist in the area, but the dental surgeon must have the knowledge to diagnose and treat, when OA is the therapeutic option. The interpretation of polysomnography, na exam that diagnoses and leads to the correct choice of treatment, and cephalometric data are the main requirements for the Dental Surgeon who proposes to treat patients with OSAHS. In this work, a questionnaire was developed and applied to dentalsurgeons from three different cities in the State of São Paulo so that it was possible to assess the knowledge of these professionals regarding the diagnosis and treatment of OSAHS. 70 Dental Surgeons were interviewed and the results showed that 70% of them are interested in working with AIOs. This group had a statistically significant relationshipwith those who stated that they had already been asked by a patient about this treatment. Regarding the creation of a specialty for this area, professional in the area of ??prosthesis and implant were more interested. And, of the total number of respondents, only 25% have already had contact with this type of device, but do not know the care protocol for the treatment of these patients(AU)

Prevalence of mild, moderate, and severe OSA was 28.8%, 15.1%, and 34.9%, respectively. Proportions of diabetes and hypertensionwere significantly high among patients with obstructive sleep apnea. Correlation analysis revealed a weak positive linear relationship (r=0.14) between the number of risk factors and the AHI score.Conclusions:Thisstudy showed high prevalence of OSA among out patients presented with suspected sleep disordered breathing. Hypertension, diabetes and obesity were highly prevalent CV comorbidities among South Indian patients diagnosed with OSA.

Syndrome d'apnées-hypopnées obstructives du sommeil: état des lieux des connaissances et de la pratique des médecins généralistes dans la ville de Kinshasa / Apneas-obstructive sleep hypopneas syndrome: state of the knowledge and practice of generalist physicians in the city of Kinshasa

Contexte et objectif. Le syndrome d'apnées hypopnées obstructives du sommeil (SAHOS) est une pathologie fréquente, mais méconnue. L'objectif de cette enquête était d'évaluer les connaissances ainsi que les habitudes diagnostique et thérapeutique des médecins généralistes (MG) vis-à-vis le SAHOS. Méthodes. Etude transversale, déclarative, observationnelle menée auprès des MG de la ville de Kinshasa, à partir d'un questionnaire anonyme n'ayant pas précisé au préalable l'objet de l'étude. Les réponses aux questions et le nombre des répondants sont exprimés en fréquence et en pourcentage. Résultats. Sur 177 MG ayant répondu au questionnaire, près de 70% avaient obtenu leur diplôme après l'année 2009. Le cursus universitaire avait été la principale source d'information. La majorité des MG de l'enquête (62%) n'était pas familiarisée avec le SAHOS. Les symptômes cardinaux (ronflements, apnées nocturnes, somnolence diurne) avaient été cités par plus de moitié des MG mais sans leur donner de signification réelle dans leur pratique médicale. L'obésité a été largement citée comme un facteur associé au SAHOS par 68 % de MG, cependant les autres facteurs ont été méconnus ou à peine cités. Plus de la moitié des MG (54,2 %) ne connaissait pas les répercussions et les complications des apnées nocturnes sur l'individu et son environnement. La polysomnographie comme examen clé du SAHOS avait été citée par 56 % des MG. Le niveau des connaissances révélé par l'ensemble des résultats s'est avéré globalement faible. Conclusion. Le SAHOS est une pathologie fréquente, méconnue et très peu intégrée dans les pratiques professionnelles médicales à Kinshasa. Cette situation appelle un approfondissement de la formation des médecins par l'enseignement universitaire et la formation médicale continue

Context and objective. Obstructive sleep apneahypopnea syndrome (OSAHS) is a frequent pathology. The objective was to assess the knowledge as well as the diagnostic and therapeutic habits of general practitioners (GPs) concerning the OSAHS. Methods. A crosssectional, observational study was conducted among GPs using an anonymous questionnaire that did not specify the purpose of the study beforehand. Results. Out of 177 GPs who answered the questionnaire, almost 70 % had graduated after 2009. University education had been the main source of information. The majority of GPs in the survey (62%) were not familiar with OSAHS. Cardinal symptoms of OSAHS (snoring, nocturnal apnea, daytime sleepiness) had been cited by more than half of GPs but without giving them any real significance in their medical practice. Half of them had never discussed the diagnosis of OSAHS with their patients. Obesity was widely cited as a factor associated with OSAHS by 68% of GPs, however other factors were either unrecognized or barely mentioned. More than half of GPs (54.2%) did not know the repercussions and complications of night apnea on the individual and his environment. Polysomnography as a key examination for OSAHS was cited by 56% of GPs. The existence of care was also indicated by a large number of them (87%) but without knowing the terms. Conclusion. OSAHS is a pathology affecting the population of Kinshasa, but little integrated into professional medical practices. Its cardinal symptoms, complications and diagnostic and therapeutic modalities are little known to GPs. This situation calls for further training of doctors through university education and continuing medical education.

Effect of transitional nursing combined with resistance breathing training on elderly obese obstructive sleep apnea-hypopnea syndrome / 中国实用护理杂志

Objective:To analyze the effect of transitional care model (TCM) mode combined with resistance breathing training on hypoxic reactivity of respiratory center in elderly obese obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods:Totally 78 patients with OSAHS who met the criteria were selected from the geriatric department of Nanjing Drum Tower Hospital from January 2018 to December 2020 and divided into observation group and control group by random digits table method, with 39 cases in each group; the control group was intervened by basic nursing combined with resistance breathing training mode, and the observation group was intervened by TCM mode on the basis of the control group. Before nursing and 1 month after discharge, Pittsburgh Sleep Quality Index (PSQI), Short-Form 36-item Health Survey (SF-36), Montreal Cognitive Assessment (MoCA) were used to evaluate the sleep quality, quality of life and cognitive function of the patients. Besides, FVC, FEV 1, FEV 1/FVC were also tested before nursing and 1 month after discharge. Results:One month after discharge, the daytime dysfunction, use of sleep drugs, habitual sleep efficiency, subjective sleep quality, sleep disorder, sleep latency, sleep duration and total score of PSQI in the observation group were significantly lower than those in the control group (the control group: 2.27 ± 0.34, 2.03 ± 0.31, 2.09 ± 0.23, 1.85 ± 0.28, 2.11 ± 0.28, 1.40 ± 0.24, 2.12 ± 0.41, 13.87 ± 0.56; the observation group: 1.63 ± 0.33, 1.22 ± 0.29, 1.63 ± 0.29, 1.12 ± 0.31, 1.35 ± 0.34, 1.09 ± 0.28, 1.74 ± 0.26, 9.78 ± 0.59) ( t values were 4.91-31.61, all P<0.01). One month after discharge, the scores of mental health, physical pain, physiological function, physiological function, emotional function, life vitality, social function and overall health of SF-36 in the observation group were significantly higher than those in the control group (the control group: 62.83 ± 6.31, 68.94 ± 5.91, 61.99 ± 5.98, 64.85 ± 6.13, 43.28 ± 5.74, 64.85 ± 6.12, 61.21 ± 5.74, 62.31 ± 6.85; the observation group: 69.81 ± 5.74, 76.12 ± 6.02, 70.84 ± 6.08, 71.74 ± 5.99, 50.93 ± 6.12, 70.52 ± 5.94, 69.89 ± 5.53, 68.41 ± 4.99)( t values were 4.18-7.77, all P<0.01). One month after discharge, the scores of visual space and executive function, attention, language, delayed recall, orientation, abstraction and total score of MoCA in the observation group were significantly higher than those in the control group (the control group: 4.48 ± 0.37, 5.23 ± 0.29, 2.43 ± 0.27, 3.37 ± 0.31, 5.01 ± 0.33, 5.27 ± 0.26, 25.79 ± 1.17; the observation group:4.95 ± 0.31, 5.68 ± 0.27, 2.67 ± 0.24, 3.98 ± 0.19, 5.47 ± 0.28, 5.64 ± 0.23, 28.39 ± 1.09)( t values were 4.17-10.51, all P<0.01). One month after discharge, the levels of FVC, FEV 1 and FEV 1/FVC in the observation group were significantly higher than those in the control group, the control group: (2.59 ± 0.18) L, (1.60 ± 0.14) L, (61.78 ± 4.01)%; the observation group: (2.89 ± 0.19) L, (1.99 ± 0.17) L, (68.86 ± 3.99)% ( t = 7.21, 11.14, 7.87, all P<0.05). Conclusions:TCM combined with resistance breathing training can effectively improve the hypoxic response of respiratory center in elderly obese patients with OSAHS.

Application of NoSAS score, STOP-BANG Questionnaire and Epworth sleepiness scale in evaluating obstructive sleep apnea risk in patients with respiratory disease / 国际生物医学工程杂志

Objective:To compare the value of NoSAS score, STOP-BANG questionnaire (SBQ) and Epworth Sleepiness Scale (ESS) in assessing the risk of obstructive sleep apnea hypopnea syndrome (OSAHS) in patients with respiratory disease (RD).Methods:The clinical data, NoSAS, SBQ and ESS scores of 190 patients who underwent overnight polysomnography (PSG) were collected. According to the receiver operating characteristic (ROC) curve, with different apnea-hypopnea index (AHI) as the judgment cutoff, the sensitivity, specificity, positive predictive value, negative predictive value, diagnostic odds ratio (DOR) and accuracy of the three scales were compared.Results:With AHI ≥5 times/h as the cutoff, the area under the ROC curve (AUC) of NoSAS and SBQ were 0.833 and 0.729, respectively, indicating that both have predictive value for mild OSAHS. Among them, NoSAS had a larger DOR value (16.150), indicating that NoSAS had the higher accuracy in assessing the risk of mild OSAHS. When AHI>15 times/h was used as the cutoff, the AUC value of NoSAS was 0.704, indicating that it has predictive value for moderate OSAHS. When AHI>30 times/h was used as the cutoff, the AUC value (0.706) and DOR value (6.527) of SBQ were high, indicating that it has predictive value and good accuracy for severe OSAHS. The SBQ is more sensitive than NoSAS and ESS when evaluating patients at high risk for OSAHS ( SBQ≥3). Conclusions:When evaluating the risk of mild and moderate OSAHS in RD patients, NoSAS is better than SBQ and ESS, and when evaluating severe OSAHS, SBQ is better than NoSAS and ESS. In clinical work, appropriate predictive tools should be selected according to the actual situation to assess the risk of OSAHS, so as to formulate and implement early intervention plans based on the assessment results.

Progress on the influence of seasonal and environmental factors on OSAHS in children / 国际儿科学杂志

Obstructive sleep apnea hypopnea syndrome(OSAHS) is one of the common diseases harmful to children′s health.OSAHS is a disease characterized by complete or partial obstruction of the upper respiratory tract, accompanied by blood gas changes and atypical sleep patterns.The incidence of OSAHS is on the rise.OSAHS can cause a series of physical, mental and developmental abnormalities in children, resulting in negative consequences for children.Common causes of OSAHS in children include mechanisms such as compliance changes caused by increased upper airway resistance and influence of neural regulation.Meanwhile, studies have shown that season、environmental factors have certain effects on the incidence and severity of OSAHS and sleep structure.This paper reviews the effects of season and environmental factors on children with OSAHS.

The experience of adult inpatients with obstructive sleep apnea-hypopnea syndrome after surgery: a qualitative research / 中国实用护理杂志

Objective:To explore the experience of the postoperative adult patients with obstructive sleep apnea-hypopnea syndrome from the patients′ angle and to provide references for improving the postoperative comfort of the patients.Methods:The phenomenology research method was adopted in this study. Thirteen postoperative adult patients with obstructive sleep apnea-hypopnea syndrome from Department of Otolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology participated in the in-depth interview with the interview outline. Data were analyzed by using Colaizzi′s phenomenological method.Results:Three level-1 themes and ten level-2 themes were extracted. The physical discomfort included throat discomfort, lacking of enough sleep at night, restricted diet, limitation in speaking. The negative emotion included the sense of worry, helplessness, fidget and regret. The wish of support included the wish of coping strategy and being understanded.Conclusions:The main uncomfortable experience of the patients is the throat discomfort which has the chain reaction and causes the other discomfort. So the nurses should inquire patients initiatively, cooperate with doctors and patients′ family members to relieve patients′ discomfort particularly at night, and then the patients′ quality of life, nurse-patient relationship and patients′ satisfaction may be improved.

Effect of information-motivation-behavior skills on adherence of continuous positive airway pressure therapy in patients with obstructive sleep apnea hypopnea syndrome / 中南大学学报(医学版)

OBJECTIVES@#Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common disease that seriously affects health. Continuous positive airway pressure (CPAP) therapy is the preferred treatment for moderate-to-severe OSAHS patients. However, poor adherence to CPAP is a major obstacle in the treatment of OSAHS. Information-motivation-behavioral (IMB) skills, as a kind of mature technology to change the behavior, has been used in various health areas to improve treatment adherence. This study aims to explore the effects of the IMB skills intervention on CPAP adherence in OSAHS patients.@*METHODS@#Patients who were primary diagnosed with moderate-to-severe OSAHS were randomly divided into the IMB group (n=62) and the control group (n=58). The patients in the IMB group received CPAP therapy and the IMB skills intervention for 4 weeks. The patients in the control group received CPAP therapy and a usual health care provided by a registered nurse. We collected the baseline data of the general information, including age, sex, body mass index (BMI), the Epworth Sleepiness Scale (ESS) score, the Hospital Anxiety and Depression Scale (HADS) score, and indicators about disease severity [apnea-hypopnea index (AHI), percentage of time with arterial oxygen saturation SaO2<90% (T90), average SaO2, lowest SaO2, arousal index]. After CPAP titration, we collected CPAP therapy-relevant parameters (optimal pressure, maximum leakage, average leakage, 95% leakage, and residual AHI), score of satisfaction and acceptance of CPAP therapy, and score of willingness to continue CPAP therapy. After 4 weeks treatment, we collected the ESS score, HADS score, CPAP therapy-relevant parameters, effective CPAP therapy time per night, CPAP therapy days within 4 weeks, CPAP adherence rate, score of satisfaction and acceptance of CPAP therapy, and score of willingness to continue CPAP therapy. Visual analog scale (VAS) of 0-5 was used to evaluate the satisfaction and acceptance of IMB intervention measures in the IMB group.@*RESULTS@#There were no significant differences in the baseline level of demographic parameters, ESS score, HADS score, disease severity, and CPAP therapy related parameters between the IMB group and the control group (all P>0.05). There were no significant differences in score of willingness to continue CPAP therapy, as well as score of satisfaction and acceptance of CPAP therapy after CPAP titration between the IMB group and the control group (both P>0.05). After 4 weeks treatment, the ESS score, HADS score, maximum leakage, average leakage, and 95% leakage of the IMB group were significantly decreased, while the score of satisfaction and acceptance of CPAP therapy and willingness to continue CPAP therapy of the IMB group were significantly increased (all P<0.05); while the above indexes in the control group were not different before and after 4 weeks treatment (all P<0.05). Compared with the control group, the ESS score, HADS score, maximum leakage, average leakage, and 95% leakage of the IMB group after 4 weeks treatment were significantly lower (all P<0.05); the effective CPAP therapy time, CPAP therapy days within 4 weeks, score of satisfaction and acceptance of CPAP therapy, score of willingness to continue CPAP therapy of the IMB group were significantly higher (all P<0.05). The rate of CPAP therapy adherence in 4 weeks of the IMB group was significantly higher than that of the control group (90.3% vs 62.1%, P<0.05). The VAS of overall satisfaction with IMB skills intervention measures was 4.46±0.35.@*CONCLUSIONS@#IMB skills intervention measures can effectively improve the adherence of CPAP therapy in OSAHS patients, and is suitable for clinical promotion.

Research progress of obstructive sleep apnea hypopnea syndrome and ocular surface diseases / 国际眼科杂志(Guoji Yanke Zazhi)

Obstructive sleep apnea hypopnea syndrome(OSAHS)is a group of diseases which occurred in the upper respiratory tract with transient, recurrent, partial or complete obstruction during night sleep. It can affect the regulation of hemodynamics, endocrine systems and autonomic nerve, and then result in the reduction of body oxygen saturation, chronic hypoxia and hypercapnia. Beside being an independent risk factor for cardiovascular and cerebrovascular diseases, many studies have shown that it is also associated with ocular surface diseases in OSAHS, such as floppy eyelid syndrome, dry eye, keratoconus, etc., but there is still a lack of perfect systematic analysis. This paper reviews the relationship between OSAHS and relevant ocular surface diseases including pathogenesis,clinical manifestations and treatment progress, in order to reduce the ophthalmic complications of OSAHS patients in clinical diagnosis and treatment,and better improve the quality of life of patients.

A study to identify obstructive sleep apnea syndrome based on 24 h ambulatory blood pressure data / 生物医学工程学杂志

Sleep apnea causes cardiac arrest, sleep rhythm disorders, nocturnal hypoxia and abnormal blood pressure fluctuations in patients, which eventually lead to nocturnal target organ damage in hypertensive patients. The incidence of obstructive sleep apnea hypopnea syndrome (OSAHS) is extremely high, which seriously affects the physical and mental health of patients. This study attempts to extract features associated with OSAHS from 24-hour ambulatory blood pressure data and identify OSAHS by machine learning models for the differential diagnosis of this disease. The study data were obtained from ambulatory blood pressure examination data of 339 patients collected in outpatient clinics of the Chinese PLA General Hospital from December 2018 to December 2019, including 115 patients with OSAHS diagnosed by polysomnography (PSG) and 224 patients with non-OSAHS. Based on the characteristics of clinical changes of blood pressure in OSAHS patients, feature extraction rules were defined and algorithms were developed to extract features, while logistic regression and lightGBM models were then used to classify and predict the disease. The results showed that the identification accuracy of the lightGBM model trained in this study was 80.0%, precision was 82.9%, recall was 72.5%, and the area under the working characteristic curve (AUC) of the subjects was 0.906. The defined ambulatory blood pressure features could be effectively used for identifying OSAHS. This study provides a new idea and method for OSAHS screening.

Cone-beam computed tomography study of upper airway morphology in children with obstructive sleep apnea-hypopnea syndrome / 口腔疾病防治

Objective @#To evaluate the morphology of the upper airway of children with obstructive sleep apnea-hypopnea syndrome (OSAHS) using cone-beam computed tomography (CBCT) combined with polysomnography (PSG) and provide references for clinical practice.@*Methods@# CBCT data of 45 OSAHS children and 45 normal children and PSG data of the OSAHS group were retrospectively collected. Three-dimensional reconstructions were performed using NNT 9.0 software. The total upper airway volume, nasopharyngeal volume, palatopharyngeal volume, glossopharyngeal volume, laryngopharyngeal volume, minimum cross-sectional area, anterior-posterior diameter of the minimum cross-section, and lateral diameter of the minimum cross-section were measured and recorded. According to PSG monitoring results, patients with an obstructive apnea hypopnea index (OAHI) and lowest oxygen saturation (LSaO2) were assessed. Body mass index (BMI) was recorded. The correlation between airway volume parameters, BMI and PSG test results was analyzed. @*Results@#The total upper airway volume, nasopharyngeal volume, palatopharyngeal volume, glossopharyngeal volume, laryngopharyngeal volume, minimum cross-sectional area, anterior-posterior diameter of the minimum cross-section, and lateral diameter of the minimum cross-section of the OSAHS group were significantly reduced compared with those of the control group (P<0.05). In the OSAHS group, the total upper airway volume, the minimum cross-sectional area and the lateral diameter of the minimum cross-section showed moderate negative correlations with the obstructive apnea hypopnea index (OAHI) (P<0.05). Moreover, the total upper airway volume, minimum cross-sectional area, anterior-posterior diameter of the minimum cross-section and lateral diameter of the minimum cross-section showed no correlation with the minimum blood oxygen saturation (P>0.05). No significant correlation was noted between BMI and PSG in the OSAHS group (P>0.05).@*Conclusion @#The morphology of the upper airway of children with OSAHS was significantly smaller than that of normal children. CBCT three-dimensional technology for analyzing the upper airway has a certain value in evaluating the morphology and degree of obstruction of the upper airway in children with OSAHS.

Diagnostic methods and criteria of obstructive sleep apnea hypopnea syndrome in children / 口腔疾病防治

@#Obstructive sleep apnea hypopnea syndrome (OSAHS), which is a common childhood disease, is a trending topic in clinical multidisciplinary research due to its detriment to the growth and development of children. Due to the wide variety and specificity of pathogenesis and clinical manifestations, the clinical diagnosis of OSAHS is sophisticated and difficult and remains controversial in the field. This review summarizes the common diagnostic methods in OSAHS for children, including polysomnography,which is known as the current “gold standard”, pulse oximetry, fiberoptic nasopharyngoscopy, nasopharyngeal lateral X-ray, CT, and magnetic resonance imaging (MRI). Furthermore, it emphasizes the new diagnostic critical value from Chinese guidelines for the diagnosis and treatment of obstructive sleep apnea in children (2020) for children with OSAHS released by China in 2020: the obstructive apnea hypopnea index (OAHI) is ≥ 1 time/h; it also emphasizes the importance of history and physical examination to contribute to clinical diagnosis and treatment for children with OSAHS.
