Objective To assess the clinical effectiveness and safety of uvulopalatopharyngoplasty （UPPP） in the treatment of snoring and obstructive sleep aponea syndrome （OSAS ）. Methods MEDLINE （1966 -2005 ）, EMBASE （1984 - 2005 ）, The Cochrane Library （Issue 1, 2005 ）, CBM （1979 - 2005 ）, CNKI （1994 - 2005 ）, VIP （ 1989 - 2005 ）, CMCC （1994-2005） ,Wanfang Database and Internet were searched in English and Chinese versions. Randomized controlled trials（ RC,Ts）, quasi-randomized controlled trials and prospective cohort studies were included. Study quality was evaluated by two researchers independently. RevMan4.2.7 was used for meta-analysis.Results Twelve studies were included, of which 5 were RCTs, 7 were prospective cohort studies. Compared with dental appliance（DA）, PSG （polysomnography） changes of DA group were larger than UPPP group, but patients of UPPP group had better quality of life and compliance. Comparing UPPP with LAUP （laser-assisted uvulopalatpharyngoplasty ） and RFTVR （radiofrequency tissue volume reduction）, the postoperative pain of the latter two was less than UPPP. About complications, UPPP and LAUP had no difference except for nasal reflux at 1 week after operation, there was no statistical difference between UPPP and RFTVR. There was no study to compare the PSG change among the three groups. Comparing UPPP with CPAP （continuous positive airway pressure）, PSG changes were larger in CPAP. Conclusions At present, there is no evidence to assure that UPPP is better than other treatments for snoring and OSAS or to suggest which type of surgery is most effective.The literature search is restricted to the publications of English and Chinese language, which may have resulted in missing some studies; the evidence is still weak due to the poor quality and a small number of included studies. There is an urgent need for high quality RCTs to be carried out.
睡眠呼吸障碍（sleep breathing disorders，SDB）是一种常见病、多发病，其主要类型是阻塞性睡眠呼吸暂停综合征（OSAS），特点是夜间睡眠过程中上气道完全或部分阻塞及呼吸中枢驱动降低导致呼吸暂停及低通气，产生慢性间歇性低氧、反复微觉醒、睡眠结构异常、自主神经功能紊乱等。OSAS近年已公认是一种全身性疾病，它可引起或加重许多疾病,美国心脏协会/美国心脏病学基金会（AHA/ACCF）联合发表了《睡眠呼吸暂停与心血管疾病的科学共识》。为了进一步认识两者之间的关系，提升OSAS及相关疾病防控水平，中华医学会呼吸病分会睡眠学组与心血管病学组就SDB与心血管疾病相关问题达成共识，为多学科联合防治SDB提供了科学依据。
Objective To investigate the prevalence and risk factors of sleep-disordered breathing (SDB) in patients with different severity of chronic kidney diseases (CKD). Methods A total of 144 patients of non-dialysis CKD patients in nephrology unit were recruited in the study. The patients were divided into CKD 1-2 period, CKD 3-4 period, and CKD5 period according to the severity of renal function. Results The prevalence of moderate SDB in CKD 1-2 period, CKD 3-4 period and CKD5 period were 30.0%, 53.5% and 60.5%, respectively (P=0.03), the prevalence of nocturnal hypoxemia were 23.3%, 56.3% and 65.1%, respectively ( P=0.001), and the prevalence of excessive daytime sleepiness (EDS) were 33.3%, 57.7% and 62.8%, respectively (P=0.032). Logistic regression analysis showed that age, male, body mass index (BMI), hypertension, diabetes and heart failure were independent risk factors for CKD merged with moderate to severe SDB, and the highest risk factor was heart failure (OR=7.034, 95%CI 1.255-39.420). Compared with CKD 1-2 period and CKD 3-4 period, the risk degree of CKD5 period was higher (OR=3.569 95%CI 1.324-9.620). Correlation analysis showed that glomerular filtration rate (eGFR) was negatively correlated with sleep apnea-hypopnea index (AHI) (r=–0.327, P=0.000). Conclusions There is a high prevalence of SDB (predominantly obstructive) in CKD patients and the increased risk of SDB is significantly associated with decreased eGFR among these patients. Associated comorbidities in CKD patients, especially for cardiac dysfunction, are important risk factors for SDB.
In order to promote the clinical diagnosis and treatment of obstructive sleep apnea (OSA) in Chinese children, it is urgent to construct evidence-based guidelines. The protocol and a formal version of the “Chinese guideline for Diagnosis and Treatment of Obstructive Sleep Apnea in Children” will be drawn up by referring to the “World Health Organization Guidelines Development Manual”. This protocol mainly introduces development methodology and process of guideline, including the significance, purpose, target population, users, members of the designated group, collection and determination of clinical problems and outcome indicators, evidence acquisition, evaluation and synthesis, the generation of recommendations and so on.
Sleep-related breathing disorder (SRBD) is a sleep disease with high incidence and many complications. However, patients are often unaware of their sickness. Therefore, SRBD harms health seriously. At present, home SRBD monitoring equipment is a popular research topic to help people get aware of their health conditions. This article fully compares recent state-of-art research results about home SRBD monitors to clarify the advantages and limitations of various sensing techniques. Furthermore, the direction of future research and commercialization is pointed out. According to the system design, novel home SRBD monitors can be divided into two types: wearable and unconstrained. The two types of monitors have their own advantages and disadvantages. The wearable devices are simple and portable, but they are not comfortable and durable enough. Meanwhile, the unconstrained devices are more unobtrusive and comfortable, but the supporting algorithms are complex to develop. At present, researches are mainly focused on system design and performance evaluation, while high performance algorithm and large-scale clinical trial need further research. This article can help researchers understand state-of-art research progresses on SRBD monitoring quickly and comprehensively and inspire their research and innovation ideas. Additionally, this article also summarizes the existing commercial sleep respiratory monitors, so as to promote the commercialization of novel home SRBD monitors that are still under research.
