ObjectiveThis cross-sectional clinical study evaluated the associations between sociodemographic, occupational, clinical conditions, psychological and sleep quality variables on definite sleep bruxism (SB).MethodsAll records obtained from adults (aged 20–60 years) and the elderly (aged >60 years) who had undergone polysomnography (PSG) at a private medical outpatients’ clinic from July 2017 to February 2018 were reviewed. Data from a questionnaire, based on the criteria of the American Academy of Sleep Medicine (AASM), were also gathered. Definite SB data pattern distribution was analyzed, and multivariate Poisson regression with robust variance was used to assess the associations between definite SB diagnosis, determined via PSG recordings, and the independent variables. A significance level of 5% was adopted.ResultsA total of 240 individuals were included in the study and the SB prevalence was 7.08% (n = 17). The adjusted Poisson regression analysis revealed association between definitive SB and individuals with respiratory allergy (PR = 3.63; 95% CI:1.01–13; P = 0.047) and restless sleep (PR = 2.97; 95% CI:1.04–8.50; P = 0.042).ConclusionThis study found associations between definite SB and clinical conditions (respiratory allergy) and sleep behavior (restless sleep). Knowledge regarding factors associated with definite SB can contribute to decision making in the clinical setting and management strategies involving a multidisciplinary approach. 相似文献

ObjectiveLimited information is currently available on 24-h ambulatory blood pressure (ABP) changes after adenotonsillectomy (T&A) in children with obstructive sleep apnea (OSA). In this study, the trajectory of 24-h ABP changes after surgery in children with OSA was examined at three-month and six-month follow-up.MethodsChildren aged 4–16 years with clinical symptoms of OSA and polysomnography (PSG)-diagnosed OSA (apnea-hypopnea index [AHI] >1) were included. All the children received T&A. PSG was conducted before and after surgery. Twenty four hour ABP was monitored using the linear mixed model before, three months after, and six months after surgery.ResultsIn total, 122 children were examined (mean age: 7.9 years; 71% were boys). The AHI significantly decreased from 12.7 ± 16.7 to 2.4 ± 3.2 events/h after T&A (P < 0.001). Overall diastolic blood pressure (DBP; from 65.1 to 63.4 mmHg, P = 0.01) and night-time DBP (from 57.4 to 55.4 mmHg, P = 0.032) decreased nonsignificantly during the six-month postoperative period. The OSA children with presurgical hypertension exhibited significant reductions in overall systolic blood pressure (SBP), overall DBP, daytime DBP, night-time SBP, and night-time DBP at the three-month and six-month postoperative follow-up (all P < 0.05). The three-month and six-month ABP data did not differ significantly in the entire cohort, even between children with presurgical hypertension and non-hypertensive children.ConclusionThe 24-h ABP decreased significantly in the OSA children with hypertension at three and six months after surgery. Moreover, ABP findings did not differ significantly between the three- and six-month follow-up. 相似文献

ObjectiveSleep complaints are frequent after acute COVID-19. Aim of this study was to videopolysomnographically evaluate sleep and sleep disorders after SARS-Cov2 infection.MethodsPatients with suspected sleep disorders after acute COVID-19 underwent video-polysomnography (v-PSG) at the Sleep Disorders Clinic, Department of Neurology, Medical University Innsbruck. V-PSG was conducted 4.2 (SD = 1.3) months after diagnosis of SARS-CoV-2 infection.ResultsEleven patients [nine men, age 52.5 (SD = 11.7) years; BMI 29 (SD = 5.2) kg/m2] were included. At 60 days follow-up after diagnosis, persisting breathing complaints were present in 7/11 (64%) patients. After v-PSG four patients (36%) were diagnosed with obstructive sleep apnea (OSA). Respiratory frequency during sleep was normal and no tachypnea, thoracoabdominal asynchrony, or periodic deep sighing were detected. Four patients (36%) showed REM sleep without atonia (RWA), and two additional patients showed an RWA index within the highest range of normality.ConclusionWe report videopolysomnographic findings in a series of eleven patients after acute COVID-19. A major finding of this study was the presence of isolated RWA, a recognized prodromal stage of RBD, in more than one third of the patients. Future videopolysomnographic investigations including quantification of RWA in patients after COVID-19 will give more insights into a possible acute or post-infectious CNS pathology related to the SARS-CoV-2 infection. 相似文献

ObjectivesPediatric obesity and sleep-disordered breathing (SDB) are strongly associated, and both promote metabolic impairments. However, the effects of a lifestyle intervention on the overall metabolic syndrome (MetS) are unknown. The objectives were i) to evaluate the effects of a lifestyle intervention on cardiometabolic risk (CMR), assessed with a dichotomous (MetS) and a continuous (MetScoreFM) instrument, in obese adolescents with and without SDB and ii) to compare the post-intervention cardiometabolic responses between adolescents with persistent (apnea-hypopnea index; AHI≥2) or normalized-SDB (AHI<2).MethodsSeventy-six adolescents with obesity recruited from two specialized institutions underwent a 9–12month diet and exercise intervention. Sleep and SDB (AHI≥2) were studied by polysomnography. Anthropometric parameters, fat mass (FM), glucose, insulin, lipid and leptin profiles, blood pressure (BP), MetScoreFM and MetS were assessed pre- and post-intervention. We performed comparisons between Non-SDB and SDB groups and between Normalized-SDB and Persistent-SDB subgroups.ResultsFifty participants completed the study. Pre-intervention, twenty youth had SDB (40%) with higher insulin concentrations and systolic BP than Non-SDB participants (p < 0.01), for a similar degree of obesity. Post-intervention, MetScoreFM (p < 0.001) and MetS prevalence (p < 0.05) were decreased in both groups. Eleven participants (55%) normalized SDB along with a decrease in insulin concentrations and BP (p < 0.05). Triglycerides, total cholesterol and LDL-cholesterol concentrations (p < 0.01) improved equally in the Normalized and Persistent-SDB subgroups.ConclusionSDB was associated with lower insulin sensitivity and higher BP but did not affect the lipid profile. A diet and exercise lifestyle intervention is effective in decreasing the CMR whether or not SDB was normalized in obese adolescents. 相似文献

IntroductionWe aimed to investigate the effects of changes in sleep architecture on long-term clinical outcome in patients with Parkinson's disease (PD) who underwent deep brain stimulation of subthalamic nuclei (STN DBS).MethodsWe followed up eight PD patients before and three years after STN DBS surgery. In addition to clinical assessments, polysomnography (PSG) followed by multiple sleep latency tests was performed before and after STN DBS, while stimulator was ON and OFF.ResultsSubjective sleep latency was significantly decreased (P = 0.033) and sleep duration was increased (P = 0.041), as measured by Pittsburgh sleep quality index. Latency to REM sleep stage was shortened after surgery with STN DBS ON (P = 0.002). Index of central type of abnormal respiratory events was significantly increased while stimulator was ON (P = 0.034). Total number of major body movements was found to be increased when stimulator was turned OFF (P = 0.012). Among PSG data obtained during STN DBS ON, it was observed that duration of N3 sleep was negatively correlated with UPDRS scores at 1st (P = 0.038) and 3rd (P = 0.045) post-operative years. Among PSG variables during STN DBS OFF, durations of N3 sleep (P = 0.017) and REM sleep (P = 0.041) were negatively correlated with UPDRS scores at post-operative 1st year.ConclusionDisturbances in sleep architecture are associated with higher UPDRS scores and worse prognosis at 1st and 3rd post-operative years. Similar results obtained while stimulator was OFF at the end of 1st year support the presence of microlesion effect after STN DBS, which is probably not long lasting. 相似文献

目的 研究肥胖儿童合并阻塞性睡眠呼吸暂停(obstructive sleep apnea,OSA)的临床特征。 方法 对在深圳市儿童医院呼吸科行多导睡眠监测的肥胖并诊断为OSA的33例7~15岁儿童的临床资料进行回顾性分析,并选取50例体重正常的、性别及年龄相匹配的OSA患儿作为对照组。 结果 33例合并肥胖的OSA儿童中,常见的日间症状前3位为:注意力不集中30例(91%),嗜睡22例(67%),晨起疲劳21例(64%);夜间症状前3位为:打鼾27例(82%),张口呼吸20例(61%),出汗16例(48%)。与正常儿童参考值相比,肥胖OSA组和对照组两组患儿浅睡眠延长,深睡眠缩短,快速动眼期明显缩短,但两组之间这些指标的比较差异无统计学意义(P> 0.05)。与对照组比较,肥胖OSA组呼吸暂停低通气指数和阻塞性呼吸暂停低通气指数均显著增加(P <0.05);快速动眼期及非快速动眼期氧减指数均显著增加(P <0.05);肥胖OSA组睡眠期间最低血氧饱和度显著低于对照组(P <0.05)。 结论 肥胖合并OSA儿童临床日间症状以注意力不集中、嗜睡、晨起疲劳为主,夜间症状以打鼾、张口呼吸、出汗为主。与体重正常OSA患儿相比,肥胖合并OSA儿童的睡眠结构无明显差别,但呼吸事件及血氧饱和度下降更严重。 引用格式: 相似文献
