Obstructive sleep apnea (OSA) is a common problem. Excessive daytime sleepiness raises a suspicion of OSA, which can be confirmed by polysomnography (PSG). Insomnia, in patients with OSA, often manifests itself as excessive daytime drowsiness. The incidence of insomnia among patients with OSA differs in different studies. Thus, we investigated the incidence of insomnia among our patients. We included 120 patients who underwent a workup due to a suspicion of OSA in the Polysomnography Laboratory, Department of Otolaryngology, Medical University of Warsaw, Poland. Patients completed the Athens Insomnia Scale (AIS). All-night PSG was done with 14-channel recordings (Grass®, USA). The severity of OSA was classified according to the apnea-hypopnea index (AHI) values. There were 96 patients with OSA and 24 patients without OSA who served as controls (their sleep disorders and daytime drowsiness were not caused by OSA). The total AIS scores tended to indicate insomnia in the entire sample and in all different subgroups. The mean AIS score was significantly different between the subgroups differing in the severity of apnea. The mean AIS score correlated significantly with sleep latency, latent sleep, and N2 latency. The mean AIS score did not correlate significantly with the AHI. In conclusion, in patients with OSA, insomnia, measured with the AIS, was associated with the severity of apnea, although this relationship was weak.

Objectives Evaluate the effects of total thyroidectomy for euthyroid goiter causing tracheal compression on the apnea hypopnea index (AHI) in patients with obstructive sleep apnea (OSA). Demonstrate a relationship between tracheal compression and OSA. Methods A retrospective study of 8 patients with euthyroid goiter causing tracheal compression who had moderate or severe OSA. Between January 2004 and December 2007, 8 patients with these conditions were treated in a community hospital by the author. At least 1 compressive symptom (dysphagia, dyspnea, and/or orthopnea) was reported by all patients. Computed tomography of the neck and chest was used to confirm the extent of goiter and tracheal compression. OSA was confirmed with preoperative polysomnography. Total thyroidectomy was performed. Postoperative polysomnography was obtained after 90 days. Outcome measures were changes in compressive symptoms and AHI using paired t test. Results All 8 patients reported symptomatic control of compressive symptoms after thyroidectomy. 7 of 8 patients demonstrated postoperative improvement of AHI. The mean postoperative AHI decreased significantly from 52.1 to 36.6 (P < 0.05). Conclusions Total thyroidectomy for goiter causing tracheal compression can significantly improve symptoms and AHI in those patients who have OSA. Evaluation of patients with OSA should include screening for tracheal compression from goiter.

Background: Severe obstructive sleep apnea (OSA), defined by apnea-hypopnea index (AHI) as more than 30 events per hour, was previously related to more comorbidity. However, limited studies separated the patients with AHI > 100 from those with a less severe manifestation of the disease. Objectives: The current study aimed at describing the characteristics of this subgroup and comparing them with less severe conditions. Methods: A retrospective analysis was conducted on 114 patients with OSA. Nocturnal polysomnography was used to diagnose severe OSA. Patients were categorized into two groups: (1) 60 < AHI < 100 (very severe OSA), (2) AHI ≥ 100 (extreme OSA). Demographic, medical history, and polysomnographic variables were evaluated and compared between the two groups. Results: Extreme OSA was diagnosed in 19 patients, the mean body mass index (BMI) was significantly higher in this group (39.26 ± 5.93 vs. 35.68 ± 6.45 kg/m2, P = 0.025). They also had lower minimal O2 saturation (65.68 ± 10.16 vs. 74.10 ± 8.74, P = 0.003) and more time with < 90% O2 saturation (T < 90%) (81.78 ± 22.57 vs. 58.87 ± 33.14, P = 0.01). OHS prevalence was significantly higher in the group with extreme OSA (P = 0.04). The most frequent comorbidity was hypertension, with an incidence of 60.5%, for the extreme group, although there was no significant difference between the two groups in terms of clinical associations. Conclusions: The current study results suggested that greater BMI and lower minimal O2 saturation, as well as increased T < 90%, were associated with extreme OSA, although no differences were observed in the associated diseases between the compared groups.

AbstractWe investigated gender differences in the optic nerve head (ONH) microcirculation status in association with obstructive sleep apnea (OSA) by using laser speckle flowgraphy (LSFG). We evaluated 150 men (60.5 ± 11.0 yrs) and 45 women (63.0 ± 10.6 yrs) who underwent overnight polysomnography. The mean blur rate (MBR), maximum (Max) MBR, and minimum (Min) MBR were evaluated. The parameters were analyzed separately for the tissues, vessels, and throughout the ONH (All). The apnea hypopnea index (AHI: times/hr), the lowest SpO2%, and the mean SpO2% were calculated as indicators of OSA. We investigated which MBR sections are correlated with OSA parameters separately in the men and women. All MBR sections in the women were significantly positively correlated with the lowest SpO2. In the men, no MBR section was correlated with any OSA parameters. The factors contributing independently to MBR-Tissue were height (β = 0.31) and lowest SpO2 (β = 0.30). The lowest SpO2 in the women was significantly positively correlated with Max MBR-Tissue, Max MBR-All, and Min MBR-All. Our results confirmed a gender difference in characteristics of ONH microcirculation in association with OSA.

Abstract Introduction Recently, the measurement of the hypoxic burden and apnea-hypopnea duration has been shown to correlate with mortality in patients with obstructive sleep apnea (OSA). We hypothesized that in patients with mild positional OSA (apnea-hypopnea index [AHI] &lt; 5 events/hr in the non-supine position) the hypoxic burden would be increased and apnea-hypopnea duration shortened and similar to patients with non-positional OSA. Methods Fourteen patients with positional OSA and 24 patients non-positional OSA with similar severity of OSA based on the respiratory event index (REI) were included. All patients had a home sleep apnea test for suspected OSA. The hypoxic burden was calculated by the multiplication of REI and the mean area under the desaturation curves. Results Thirty-eight patients [12 (35%) males, 50±12 yrs, BMI 35±7 kg/m2, Epworth Sleepiness Scale (ESS) 11±8, REI 10±3 events/hr, apnea-hypopnea duration 19±4 sec, mean SaO2 94±2%, lowest SaO2 79±8%, % total sleep time (TST) SaO2 &lt; 90% 11±16%, hypoxic burden 30±17 %min/hr] completed the study. Fourteen patients [9 (64%) males, 46±14 yrs, BMI 31±6 kg/m2, ESS 7±5, REI 9±3 events/hr, mean SaO2 94±2%, lowest SaO2 81±6%, %TST SaO2 &lt; 90% 4±6%] had positional OSA (supine REI 16±7 events/hr, non-supine REI 3±1 events/hr) and 24 patients had non-positional OSA [3 (13%) males, 52±10 yrs, BMI 38±7 kg/m2, ESS 12±9, REI 10±3 events/hr, mean SaO2 94±2%, lowest SaO2 77±9%, %TST SaO2 &lt; 90% 14±19%]. The hypoxic burden was elevated in both the positional and non-positional OSA patients with no difference between the groups (26±19 %min/hr and 32±15 %min/hr, respectively, p=0.13). The apnea-hypopnea duration was similar in positional and non-positional OSA patients (20±3 sec and 18±4 sec, respectively, p=0.08 sec). Conclusion In patients with mild positional OSA the hypoxic burden, which has been associated with cardiovascular mortality, is elevated and similar to patients with non-positional OSA. Support None

ObjectiveLaryngomalacia has been reported to contribute to the severity of obstructive sleep apnea (OSA) in children. It is unclear if surgical treatment of laryngomalacia improves polysomnography (PSG) outcomes in these patients. The objective of this study is to report the impact of supraglottoplasty on PSG parameters in children with laryngomalacia-related OSA.Study DesignRetrospective case series.SettingTertiary care medical center.Subjects and MethodsHistorical cohort study of consecutive children with laryngomalacia who underwent supraglottoplasty and who had undergone overnight PSG before and after surgery.ResultsForty-one patients were included in the final analysis: 22 (53.6%) were male, and 19 (46.3%) were female. The mean ± SEM age of patients at preoperative PSG was 1.3 ± 0.89 years (range, 0.003-2.9). In entire cohort, the mean obstructive apnea-hypopnea index score was reduced from 26.6 events/h before supraglottoplasty to 7.3 events/h after surgery ( P = .003). Respiratory disturbance index was reduced from 27.3 events/h before supraglottoplasty to 7.8 events/h after surgery ( P = .003). The percentage of REM sleep decreased from 30.1% ± 2.4 to 24.8% ± 1.3 ( P = .04). Sleep efficiency was improved ( P = .05).ConclusionOverall, supraglottoplasty significantly improved several PSG outcomes in children with laryngomalacia. However, mild to moderate OSA was still present postoperatively in most children. This suggested a multifactorial cause for OSA in this population.

Abstract Background Obstructive sleep apnea is a condition characterized by the complete or partial obstruction of the upper airway during sleep. This study aimed to compare the clinical and polysomnographic characteristics of our obstructive sleep apnea patients according to their positional and non-positional features. Results Two hundred eighty patients were included in the study. One hundred two patients (36.43%) were female, while 178 patients (63.57%) were male. While 88 (31.43%) of these patients were defined as positional patients, 192 (68.57%) were defined as non-positional patients. The mean age of the positional patients (46.78 ± 9.66) was lower than the mean age of the non-positional patients (50.90 ± 10.96) (p 0.001). Similarly, the mean body mass index of the positional patients (29.39 ± 3.80) was lower than the mean body mass index of the non-positional patients (33.30 ± 6.45) (p < 0.001). Neck circumference values of the positional patients (40.36 ± 2.65) were lower compared to the non-positional patients (43.32 ± 2.54) (p < 0.001). Sleep values were compared based on the presence of positional sleep apnea. In the positional patients, sleep duration, sleep efficiency (percentage), duration of stage N3, minimum, and mean saturation values were found to be higher compared to the non-positional patients, while nightlong apnea hypopnea index, apnea index, percentage of sleep time with oxygen saturation below 90%, oxygen desaturation index, mean heart rate, and periodic limb movement index values were found to be lower (p < 0.05). The rate of severe sleep apnea (7.95%) in the positional patients was lower than the non-positional patients (53.65%) (p < 0.001). Conclusion In the light of these data, positional OSA is a very important condition presented in 31.43% of OSA patients and it was determined that these patients were younger, had less body mass index, and shorter neck circumference. The rate of severe disease was found to be lower in positional OSA patients

Objective: Obstructive sleep apnea (OSA) is highly prevalent in children and requires an expensive and relatively unavailable sleep study for diagnosis. This study was undertaken to translate the previously validated OSA screening tool (POSAST) to the Thai language and assess its accuracy and test-retest reliability in at-risk symptomatic children. Study design: Prospective cross-sectional cohort study Methods: Pediatric patients clinically referred for suspected OSA who underwent overnight polysomnography (PSG) were recruited, and caregivers completed the Thai version of the POSAST. The same questionnaire was completed again after 2-4 weeks. Results: One hundred and ten subjects completed the study. The mean age was 8.4±2.9 years. The mean apnea-hypopnea index (AHI) was 10.9±11.9 events/hour. Test-retest reliability (Pearson correlation coefficient = 0.96, P<0.001) and internal consistency (Cronbach’s alpha coefficient = 0.82, P<0.001) between each question were excellent. A cumulative equation-derived score cut-off of 1.9 yielded 78.4% sensitivity and 50.0% specificity, while a numerical additive score cut-off of 8 corresponded to 81.1% sensitivity and 52.8% specificity for diagnosing moderate and severe OSA (AHI ≥5 events per hour) Conclusion: The internal consistency and reproducibility of the Thai version of the POSAST are satisfactory, display acceptable validity, and the instrument can be used for screening symptomatic Thai children for OSA.

ABSTRACT Objective: To validate the Portuguese-language version of the STOP-Bang (acronym for Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender) questionnaire, culturally adapted for use in Brazil, as a means of screening for obstructive sleep apnea (OSA) in adults. Methods: In this validation study, we enrolled patients ≥ 18 years of age, recruited between May of 2015 and November of 2016. All patients completed the STOP-Bang questionnaire and underwent overnight polysomnography. To evaluate the performance of the questionnaire, we used contingency tables and areas under the (receiver operating characteristic) curve (AUCs). Results: We included 456 patients. The mean age was 43.7 ± 12.5 years, and 291 (63.8%) of the patients were male. On the basis of the apnea-hypopnea index (AHI), we categorized OSA as mild/moderate/severe (any OSA; AHI ≥ 5 events/h), moderate/severe (AHI ≥ 15 events/h), or severe (AHI ≥ 30 events/h). The overall prevalence of OSA was 78.3%, compared with 52.0%, and 28.5% for moderate/severe and severe OSA, respectively. The most common score on the STOP-Bang questionnaire was 4 points (n = 106), followed by 3 points (n = 85) and 5 points (n = 82). An increase in the score was paralleled by a reduction in sensitivity with a corresponding increase in specificity for all AHI cut-off points. The AUCs obtained for the identification of any, moderate/severe, and severe OSA were: 0.743, 0.731, and 0.779, respectively. For any OSA, the score on the questionnaire (cut-off, ≥ 3 points) presented sensitivity, specificity, and accuracy of 83.5%, 45.5%, and 75.2%, respectively. Conclusions: The STOP-Bang questionnaire performed adequately for OSA screening, indicating that it could be used as an effective screening tool for the disorder.

Background: Wake-up stroke (WUS) accounts for a quarter of all ischemic strokes. Its conspicuous occurrence during sleep suggests that WUS may be associated with obstructive sleep apnea (OSA). We investigated the potential association among WUS, OSA, and measures of sympathetic hyperactivity. Methods: This is a cross-sectional analysis of data from the Sleep Apnea in Transient Ischemic Attack and Stroke (SLEEP TIGHT) study. Ischemic stroke patients were divided into WUS and non-WUS groups. Participants underwent polysomnography and ambulatory blood pressure monitoring. Collected data included demographic, medical, stroke characteristics (including severity by National Institutes of Health Stroke Scale), cholesterol, serum catecholamines, C-reactive protein, interleukin-6, B-type natriuretic peptide, blood pressure, and polysomnographic (apnea-hypopnea index (AHI); measures of hypoxia). Because both stroke and OSA affect men and women to varying degrees, the cohort was considered as a whole and by gender stratification. Results: Among 164 participants, 30.3% had WUS. The mean age was 62.0 ± 11.3 and the mean body mass index was 30.2 ± 7.9 kg/m2. One-hundred-and-five participants (63.6%) were males and 92 participants (56.8%) were Caucasian. Neither AHI nor OSA (AHI ≥5) frequency differed between WUS and non-WUS groups. Men tended to be more likely than women to have WUS (74.0 vs. 59.6%; p = 0.08), but this was not statistically significant. In gender-stratified analyses, men with WUS compared to men with non-WUS had significantly higher rates of severe OSA (AHI >30: 45.0 vs. 17.6%; p = 0.03) and tended toward more 3% oxygen desaturation events (57.0 ± 63.9 vs. 31.8 ± 22.9; p = 0.06). These differences were not seen in women. WUS patients tended to be of the male gender (74.0 vs. 59.6%; p = 0.08). History of stroke, hypertension, diabetes, dyslipidemia, or atrial fibrillation, serum catecholamines, and inflammatory biomarkers was no different between the groups. Low-density lipoprotein (LDL) was significantly higher in WUS (114.5 ± 36.3 vs. 101.4 ± 37.6; p = 0.04). Baseline diastolic blood pressure (DBP) was significantly greater in the WUS group. There was no difference in systolic or ambulatory blood pressure (including nighttime blood pressure) between WUS and non-WUS groups. Conclusions: WUS may be associated with severe OSA with more oxygen desaturation in men but not in women. WUS may be associated with high DBP and increased LDL cholesterol.
