Objective To evaluate the impact of age on safety, efficacy, and usage of upper airway stimulation (UAS). Study Design Multicenter observational study. Setting Thirteen US hospitals and 3 German hospitals. Subjects and Methods The ADHERE registry is a multicenter database enrolling patients undergoing UAS implantation from October 2016 to April 2018. Outcome measures included the Epworth Sleepiness Scale, apnea-hypopnea index (AHI), therapy usage, and complications. Data were segmented by age (<65 vs ≥65 years). Results Younger adults (n = 365) were a mean ± SD 52.7 ± 7.9 years old and 82% male, with a body mass index of 29.6 ± 3.8. Older adults (n = 235) were 71.1 ± 4.8 years old and 71% male, with a body mass index of 28.8 ± 3.8. Baseline AHI was similar (younger, 36.2 ± 15.9; older, 36.1 ± 14.8). Both groups had lower AHI at 12 months versus baseline ( P < .001), but the older group showed a greater reduction (7.6 ± 6.9 vs 11.9 ± 13.4, P = .01). The Epworth Sleepiness Scale score decreased from 12.3 ± 5.4 to 7.1 ± 4.8 ( P < .001) among younger adults and from 10.7 ± 5.7 to 6.3 ± 4.4 ( P < .001) among older adults. Usage was slightly higher among older adults (6.0 ± 2.0 vs 5.4 ± 2.1 hours/night, P = .02). Surgical time was similar between younger patients (2.4 ± 0.7 hours) and older patients (2.3 ± 0.7 hours, P = .40), with comparably low complications. Conclusion AHI reduction and therapy usage were found to be somewhat higher among patients aged ≥65 years who were treated with UAS. Surgical complications were low, in contrast to traditional sleep surgery.

Objective: To evaluate the impact of upper airway stimulation therapy (UAS) on swallowing function in patients with obstructive sleep apnea. Study Design: Prospective cohort study. Setting: Academic medical center. Participants and Outcome Measures: We recorded demographic, preoperative polysomnogram (PSG), operative, and postoperative PSG data. We assessed the patients swallowing function using the Eating Assessment Tool (EAT-10) dysphagia questionnaire. This was administered both pre- and postoperatively. The postoperative EAT-10 survey was administered at least 3 months after UAS implantation. Results: During the study period, 27 patients underwent UAS implantation, completed the pre- and postoperative EAT-10 questionnaire, met inclusion/exclusion criteria, and were included in the study. The cohort consisted of 16 men and 11 women with a mean age of 63.63 years. The mean preoperative BMI, Epworth Sleepiness Scale (ESS), and Apnea Hypopnea Index (AHI) were 29.37, 10.33, and 34.90, respectively. The mean postoperative ESS and AHI were 5.25 and 7.59, respectively. These were both significantly lower than the preoperative values ( P = .026 and P < .001). The mean pre- and postoperative EAT-10 scores were 0.37 and 0.22, respectively ( P = .461). Conclusion: Our data suggest that UAS likely does not lead to postoperative dysphagia.

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

Obstructive Sleep

There are several studies showing that patients with idiopathic obstructive sleep apnea (OSA) have a narrow and collapsible pharynx that may predispose them to repeated upper airway occlusions during sleep. We hypothesized that this structural abnormality may also extend to the glottic and tracheal region. Consequently, we measured pharyngeal (Aph), glottic (Agl), cervical tracheal (Atr1), midtracheal (Atr2), and distal (Atr3) tracheal areas during tidal breathing in 66 patients with OSA (16 nonobese and 50 obese) and 8 nonapneic controls. We found that Aph, Agl, and Atr1, but not Atr2 or Atr3, were significantly smaller in the OSA group than in the control group. Obese patients with OSA had the smallest upper airway area, although the nonapneic controls had the largest areas. Multiple linear regression analysis revealed that the pharyngeal area, cervical tracheal area, and body mass index were all independent determinants of the apnea-hypopnea index, accounting for 31% of the variability in apnea-hypopnea index. Aph, Agl, and Atr showed significant correlation with the body mass index. We conclude that sleep-disordered breathing is associated with diffuse upper airway narrowing and that obesity contributes to this narrowing. Furthermore, we speculate that a common pathophysiological mechanism may be responsible for this reduction in upper airway area extending from the pharynx to the proximal trachea.

The Impact

<b><i>Objective:</i></b> The purpose of this study was to evaluate the effects of nasal surgery on airflow characteristics in patients with obstructive sleep apnea (OSA) by comparing the alterations of airflow characteristics within the nasal and palatopharyngeal cavities. <b><i>Methods:</i></b> Thirty patients with OSA and nasal obstruction who underwent nasal surgery were enrolled. A pre- and postoperative 3-dimensional model was constructed, and alterations of airflow characteristics were assessed using the method of computational fluid dynamics. The other subjective and objective clinical indices were also assessed. <b><i>Results:</i></b> By comparison with the preoperative value, all postoperative subjective symptoms statistically improved (<i>p</i> &#x3c; 0.05), while the Apnea-Hypopnea Index (AHI) changed little (<i>p</i> = 0.492); the postoperative airflow velocity and pressure in both nasal and palatopharyngeal cavities, nasal and palatopharyngeal pressure differences, and total upper airway resistance statistically decreased (all <i>p</i> &#x3c; 0.01). A significant difference was derived for correlation between the alteration of simulation metrics with subjective improvements (<i>p</i> &#x3c; 0.05), except with the AHI (<i>p</i> &#x3e; 0.05). <b><i>Conclusion:</i></b> Nasal surgery can decrease the total resistance of the upper airway and increase the nasal airflow volume and subjective sleep quality in patients with OSA and nasal obstruction. The altered airflow characteristics might contribute to the postoperative reduction of pharyngeal collapse in a subset of OSA patients.

Abstract Introduction Insomnia and restless legs syndrome (RLS) are common sleep disorders that may impact obstructive sleep apnea (OSA) treatment. To our knowledge, no studies have investigated whether these comorbidities affect upper airway stimulation (UAS) therapy adherence and outcomes. This study aims to explore possible effects of insomnia and RLS in patients using UAS therapy. Methods All patients who underwent UAS system implantation for treatment of OSA at our facility were retrospectively studied. Pre- and post-implant histories and data, including diagnostic sleep testing, otolaryngology evaluation, activation results, and treatment evaluation, were analyzed. Patients with no insomnia or RLS were compared to patients with insomnia, RLS, or both. Apnea-hypopnea index (AHI), Epworth Sleepiness Scale (ESS), and adherence were compared pre- and post-treatment for each group. Results Sixty-four patients who have undergone UAS implantation at our center have completed post-treatment in-lab titration and evaluation of their UAS system. Insomnia was present in 47%, RLS in 28%, and both insomnia and RLS in 14%. In all groups, the overall AHI during in-lab titration was &gt;50% lower than the pre-treatment AHI (16.1+/-14.3/h vs 32.5+/-13.1/h, p&lt;0.001). While the trend in AHI reductions suggested a lower AHI in those without insomnia or RLS, the reduction did not reach statistical significance (no insomnia or RLS 15.7+/-12.9/h, insomnia 16.9+/-16.7/h, RLS 19.0+/-15.5/h, both insomnia and RLS 23.4+/-18.4/h). UAS therapy usage was reduced in patients with RLS (3.9+/-2.6 h/night, p=0.029) and in patients with both insomnia and RLS (3.9+/-1.3 h/night, p=0.046) compared to patients with neither comorbidity (5.9+/-1.9 h/night). Mean reduction in ESS was similar across groups, averaging from 11+/-5 pre-treatment to 7+/-5 post-treatment (p&lt;0.001). Conclusion Insomnia and RLS are common in patients using UAS therapy for OSA. Pre- and post-treatment residual AHI and ESS significantly improved in all patient groups assessed. A decrease in UAS usage was present in patients with RLS and both RLS and insomnia. Our study suggests that identification and treatment of RLS and insomnia may play an important role for UAS therapy adherence and efficacy, thus, optimizing care. Support (if any):

OBJECTIVE: In this study, we assessed the efficacy of a new method (expansion sphincter pharyngoplasty [ESP]) to treat obstructive sleep apnea. STUDY DESIGN: We conducted a prospective, randomized controlled trial. METHODS: Forty-five adults with small tonsils, body mass index less than 30 kg/m 2 , of Friedman stage II or III, of type I Fujita, and with lateral pharyngeal wall collapse were selected for the study. RESULTS: The mean body mass index was 28.7 kg/m 2 . The apnea-hypopnea index improved from 44.2 ± 10.2 to 12.0 ± 6.6 ( P < 0.005) following ESP and from 38.1 ± 6.46 to 19.6 ± 7.9 in the uvulopalatopharyngoplasty group ( P < 0.005). Lowest oxygen saturation improved from 78.4 ± 8.52% to 85.2 ± 5.1% in the ESP group ( P = 0.003) and from 75.1 ± 5.9% to 86.6 ± 2.2% in the uvulopalatopharyngoplasty group ( P < 0.005). Selecting a threshold of a 50% reduction in apnea-hypopnea index and apnea-hypopnea index less than 20, success was 82.6% in ESP compared with 68.1% in uvulopalatopharyngoplasty ( P < 0.05). CONCLUSION/SIGNIFICANCE: The ESP may offer benefits in a selected group of OSA patients.

The Impact

The aim of this study was to examine the association between body mass index and weight changes on disability transitions and mortality among Brazilian older adults. Longitudinal data from the Health, Well-Being, and Aging in Latin America and the Caribbean Study conducted in São Paulo, Brazil (2000 and 2006), were used to examine the impact of obesity on disability and mortality and of weight changes on health transitions related to disability. Logistic and multinomial regression models were used in the analyses. Individuals who were obese were more likely than those of normal weight to have limitations on activities of daily living (ADL), instrumental activity of daily living (IADL), and Nagi's limitations. Obesity was associated with higher incidence of ADL and IADL limitations and with lower recovery from Nagi's limitations. Compared to those who maintained their weight, those who gained weight experienced higher incidence of ADL and Nagi's limitations, even after controlling for initial body mass index. Higher mortality among overweight individuals was only found when the reference category was “remaining free of Nagi limitations.” The findings of the study underline the importance of maintaining normal weight for preventing disability at older ages.

Objective: To compare patients with moderate-severe obstructive sleep apnea (OSA) undergoing traditional single and multilevel sleep surgery to those undergoing upper airway stimulation (UAS). Study Design: Case control study comparing retrospective cohort of patients undergoing traditional sleep surgery to patients undergoing UAS enrolled in the ADHERE registry. Setting: 8 multinational academic medical centers. Subjects and Methods: 233 patients undergoing prior single or multilevel traditional sleep surgery and meeting study inclusion criteria were compared to 465 patients from the ADHERE registry who underwent UAS. We compared preoperative and postoperative demographic, quality of life, and polysomnographic data. We also evaluated treatment response rates. Results: The pre and postoperative apnea hypopnea index (AHI) was 33.5 and 15 in the traditional sleep surgery group and 32 and 10 in the UAS group. The postoperative AHI in the UAS group was significantly lower. The pre and postoperative Epworth sleepiness scores (ESS) were 12 and 6 in both the traditional sleep surgery and UAS groups. Subgroup analysis evaluated those patients undergoing single level palate and multilevel palate and tongue base traditional sleep surgeries. The UAS group had a significantly lower postoperive AHI than both traditional sleep surgery subgroups. The UAS group had a higher percentage of patients reaching surgical success, defined as a postoperative AHI <20 with a 50% reduction from preoperative severity. Conclusion: UAS offers significantly better control of AHI severity than traditional sleep surgery. Quality life improvements were similar between groups.

The Impact

The purpose of this study was to investigate the combined impact of obesity and physical activity (PA) on the health of older adults. Pedometer-determined steps/d, body-mass index (BMI), resting blood pressure, and fasting glucose (FG) were assessed in 137 older adults (69.0 ± 8.9 yr). The active group (>4,227 steps/d) had lower systolic blood pressure (SBP;p= .001), diastolic blood pressure (DBP;p= .028), and FG (p< .001) than the inactive group (≤4,227 steps/d). The normal-BMI group (18.5-24.9 kg/m2) had lower SBP (p< .001) and DBP (p= .01) than the obese group (≤30 kg/m2). There were no differences in SBP (p= .963) or DBP (p= 1.0) between active obese and inactive normal-BMI groups. The active obese group, however, had a more favorable FG than the inactive normal-BMI group (χ2= 18.9,df= 3,p= .001). Efforts to increase PA of older adults should receive the same priority as reducing obesity to improve BP and FG levels.
