We investigated whether advanced brain biological age is associated with accelerated age-related physical and/or cognitive functional decline: mobility impairment no disability (MIND), cognitive impairment no dementia (CIND), and physio-cognitive decline syndrome (PCDS). We constructed a brain age prediction model using gray matter features from the magnetic resonance imaging of 1482 healthy individuals (aged 18–92 years). Predicted and chronological age differences were obtained (brain age gap [BAG]) and analyzed in another 1193 community-dwelling population aged ≥50 years. Among the 1193 participants, there were 501, 346, 148, and 198 in the robust, CIND, MIND, and PCDS groups, respectively. Participants with PCDS had significantly larger BAG (BAG = 2.99 ± 8.97) than the robust (BAG = −0.49 ± 9.27, p = 0.002; η2 = 0.014), CIND (BAG = 0.47 ± 9.16, p = 0.02; η2 = 0.01), and MIND (BAG = 0.36 ± 9.69, p = 0.036; η2 = 0.013) groups. Advanced brain aging is involved in the pathophysiology of the co-occurrence of physical and cognitive decline in the older people. The PCDS may be a clinical phenotype reflective of accelerated biological age in community-dwelling older individuals. [ABSTRACT FROM AUTHOR]

The prevalence rate of obstructive sleep apnea (OSA) in the community Down syndrome (DS) children is not clear. Moreover, the impact of OSA and sleep structure on the cognitive function is inconclusive. The present study aimed to investigate 1) the prevalence rate of OSA in the community DS children and 2) the impact of OSA and sleep structure on cognitive performance. Thirty DS children aged 6–18 years were recruited and evaluated with the performance of the language domain and sensorimotor domain, combining neuropsychological tests and parent-rated behavior. The outcomes were the age-adjusted scores, of which the lower the score was, the better was the patient's ability. The association of score with OSA and sleep structures was determined by linear regression. To diminish the age-related difference, all analyses were conducted separately for all subjects and 6–12-year-old subjects. The median age was 11.3 years and median Full-Scale Intelligence Quotient (FSIQ) was 44. The prevalence of OSA (apnea–hypopnea index ≥ 1/h) was 80% and 62.5% in all subjects and 6–12-year-old subjects, respectively. For 6–12-year-old subjects, after adjustment for age and FSIQ, both %REM and OSA were associated with lower score of the subtest of language domain, WPPSI-R Vocabulary, while %REM was also associated with lower score of VABS-II Communication – Expressive. In contrary, % slow wave sleep was not associated with any subtest. This study identified that OSA may be highly prevalent in community DS children. Among 6–12-year-old DS children, OSA and % REM were associated with their language function. [ABSTRACT FROM AUTHOR]

Background: Whether the weaning outcome of solid cancer patients receiving mechanical ventilation (MV) in the intensive care unit (ICU) is comparable to that in non-cancer patients is unknown. The aim of this study was to compare the weaning outcomes between non-cancer patients and patients with different types of cancer.Methods: We studied patients requiring MV during ICU stay for medical reasons between 2012 and 2014. Cancer patients were grouped into those with lung cancer (LC), head and neck cancer (HNC), hepatocellular carcinoma (HCC), and other cancers (OC). The primary endpoint was successful weaning at day 90 after the initiation of MV, and the main secondary endpoints were 28-day and 90-day mortality after ICU admission.Results: Five hundred and eighteen patients with solid cancers and 1362 non-cancer patients were recruited. The rate of successful weaning at day 90 was 57.9% in cancer patients, which was lower than 68.9% in non-cancer patients (p < 0.001). Compared to non-cancer patients, LC was associated with a lower probability of weaning at day 90 (hazard ratio 0.565, 95% CI 0.446 to 0.715), while HNC, HCC, and OC had similar probabilities. The 28-day and 90-day mortality rates were higher in cancer patients than in non-cancer patients (45.2% vs. 29.4%, and 65.6% vs. 37.7%, respectively, both p < 0.001).Conclusion: Among mechanically ventilated patients in the ICU, those with LC were associated with a lower probability of weaning at day 90 compared to non-cancer patients.

Background Daytime sleepiness is a frequent complaint in women during pregnancy. It has also been linked to negative obstetric consequences. Although high prevalence of excessive daytime sleepiness throughout pregnancy is well-documented, neither the causes of persistent daytime sleepiness nor new-onset daytime sleepiness during pregnancy have been investigated. Identifying predictive factors may play an important role in the management of daytime sleepiness in pregnant women and improve prenatal care and maternal-fetal outcomes. Objectives To examine first-trimester maternal characteristics associated with the persistence and new-onset daytime sleepiness in pregnant women. Design A longitudinal, prospective cohort design. Setting One medical center in Taipei, Taiwan and participating women’s homes. Participants A total of 204 pregnant women. Methods First-trimester pregnant women recruited from an outpatient obstetric clinic at a medical center provided socio-demographic and health information, wore an actigraphy monitor for 7 days, and completed sleep, mood, and daytime sleepiness questionnaires. Data were collected again when the women were in the second and third trimester. Results Thirty-one (15.2%) women experienced excessive daytime sleepiness that persisted across all three trimesters. Nulliparous women and women who snored in the first trimester were 2.28 and 2.10 times more at risk of being classified of persistent daytime sleepiness than multiparous women and women who did not snore in the first trimester, respectively. Thirty-one (15.2%) women developed new-onset daytime sleepiness with advancing gestation. Women were more likely to develop new-onset daytime sleepiness if they worked longer hours per week (OR = 1.04, p < 0.001), if they reported snoring (OR = 6.75, p < 0.001), and if they had elevated depressive symptoms in the first trimester of pregnancy (OR = 1.09, p = 0.01). Conclusions Snoring in the first trimester is involved in both the persistence and new-onset of daytime sleepiness with elevated depressive symptoms related to new-onset daytime sleepiness in pregnant women. Findings suggest that intervention strategies for alleviating daytime sleepiness in pregnant women should focus on managing snoring and symptoms of depression in early trimesters with special attention to nulliparous and employed women.

Background Sleep disturbances are common in women, especially during pregnancy. Previous studies have confirmed the importance of sleep disturbances as a risk factor of adverse pregnancy outcomes and the need for screening and treatment of inadequate sleep. These reports, however, did not examine health-related quality of life which may be affected by sleep long before adverse clinical consequences are detectable in women during pregnancy. Objectives To examine the cross-sectional and longitudinal association between sleep and health-related quality of life in pregnant women. Design A prospective observational study. Setting A university-affiliated hospital in Taiwan and participants’ homes. Participants A total of 164 pregnant women completed questionnaires and wore a wrist actigraphy monitor for 7 days each trimester. Methods Objective sleep was measured by actigraphy, subjective sleep was measured by the Pittsburgh Sleep Quality Index, and health-related quality of life was measured using the SF-12v2 questionnaire across three trimesters. Multiple linear regression analyses were performed to evaluate the cross-sectional and longitudinal associations between sleep and health-related quality of life. Results Sixty-four (39.0%) women consistently had an average sleep efficiency < 85% by actigraphy and 40 (24.4%) had a Pittsburgh Sleep Quality Index global score > 5 in all three trimesters. Cross-sectionally, more actigraphic daytime sleep ( p = 0.04) and better subjective sleep quality ( p < 0.01) were associated with better physical health-related quality of life in first-trimester pregnant women. Better actigraphic sleep efficiency ( p = 0.04) and better subjective sleep quality ( p < 0.01) were associated with better mental health-related quality of life in second-trimester pregnant women. Longer actigraphic total nighttime sleep ( p < 0.01) and better subjective sleep quality ( p < 0.01) were associated with better mental health-related quality of life in third-trimester pregnant women. Longitudinally, first-trimester actigraphic total nighttime sleep ( p < 0.05) and subjective sleep quality ( p < 0.01) predicted mental health-related quality of life in the second and third trimester. Conclusions Sleep disturbances are a highly prevalent and persistent problem in pregnant women. Adequate sleep is essential for women at all pregnancy stages and improving nocturnal sleep quantity and quality in early gestation is of utmost importance for an optimal health-related quality of life later in pregnancy.

Objective: To investigate the relative contributions of obesity and obstructive sleep apnea (OSA) to unfavorable blood pressure in children.Study Design: Children aged 3-18 years with OSA-related symptoms were recruited. All children underwent office blood pressure (BP) monitoring and full-night polysomnography. Obesity was defined as a body mass index ≥95th percentile. OSA severity was divided into primary snoring (apnea-hypopnea index [AHI] <1), mild OSA (5> AHI ≥1), and moderate to severe OSA (AHI ≥5). Age- and sex-adjusted logistic regression analysis was performed to determine the associations among OSA, obesity, and elevated BP.Results: This cross-sectional study enrolled 1689 children (66% boys), with a mean age of 7.9 years. Compared with children with primary snoring, children with moderate to severe OSA had significantly higher systolic BP (108.1 mmHg vs 105.6 mmHg), diastolic BP (75.0 mmHg vs 70.4 mmHg), systolic BP percentile (75.0 vs 70.4), and diastolic BP percentile (74.0 vs 69.2). The rate of unfavorable BP (ie, elevated BP or hypertension level BP) also was significantly higher in children with more severe OSA. Children with obesity had higher BP and BP percentile. Logistic regression analysis revealed that children with obesity and moderate to severe OSA have a 3-fold greater risk of unfavorable BP compared with children without obesity and primary snoring.Conclusions: We identified a 3-fold greater risk of unfavorable BP in children with obesity and moderate to severe OSA.

Background/Purpose: The OSA-18 questionnaire is one of the most widely-used sleep quality measurements in children. We tested the applicability and cross-cultural validation of the traditional Chinese version OSA-18 questionnaire. Methods: This cross-sectional study was conducted in a tertiary medical referral center. The translation and cultural adaptation of the OSA-18 questionnaire were performed based on Brislin's revised model. A total of 109 children aged 2–18 years old with sleep problems were recruited. Overnight polysomnography and the OSA-18 questionnaire were administered. The reliability and validity of the traditional Chinese version of OSA-18 questionnaire were verified. Results: Excellent test–retest reliability and good internal consistency were achieved, and the validity of OSA-18 with overnight polysomnography was confirmed. The domain of sleep disturbance, daytime function, caregiver concerns, and the OSA-18 total scores were significantly higher in sleep apnea patients. The domain of caregiver concern had the highest score, while those of emotional distress had the lowest scores. The optimal cut-off point of the OSA-18 total scores for detecting obstructive sleep apnea was 67. Conclusion: The traditional Chinese version of OSA-18 demonstrated high reliability and good validity in our study. The domain of caregiver concern is the major element in Taiwanese children with sleep-disordered breathing. [ABSTRACT FROM AUTHOR]

Introduction: Craniofacial anatomic abnormalities related to structural narrowing of the upper airway have been reported in patients with obstructive sleep apnea syndrome (OSAS). The purpose of this study was to test whether there are sex differences in the relative contributions of specific anthropometric and cephalometric measurements of OSAS severity. Methods: The subjects were Taiwanese patients who visited the Ear, Nose, and Throat Department of National Taiwan University Hospital with complaints of snoring or sleep apnea. The anthropometric, cephalometric, and overnight polysomnographic records of 109 subjects were evaluated. Results: There are obvious sex differences in the craniofacial skeletal characteristics that contribute to OSAS severity. Male patients with the following risk factors are likely to have more severe type OSAS: increased neck size, inferiorly positioned hyoid bone, and greater anterior lower facial height. The risk factors related to the severity of OSAS in female patients include smaller posterior facial height and anteriorly positioned hyoid bone. Conclusions: To evaluate OSAS severity, different anthropometric and cephalometric measurements should be used for men and women. The craniofacial skeletal characteristics that contribute to OSAS severity were in the anterior lower portion of the profile in men and in the posterior portion of the profile in women.

Sleep disturbances are one of the most frequent chief complaints brought to the healthcare professionals during routine prenatal care visits. Sleep and mood disturbances are often intertwined, and depression in particular is a leading cause of disability and disease burden worldwide with women more likely to be affected than men. However, limited studies have prospectively investigated the association between sleep disturbances and longitudinal risk of depression in pregnant women, with no studies using actigraphy to objectively estimate daytime and nighttime sleep duration and the extent of sleep disruption. To examine the predictive and longitudinal association of objective actigraphic and subjective sleep disturbances with depressive symptoms in pregnant women. A prospective observational cohort study. 204 1st trimester pregnant women recruited from a university-affiliated hospital provided socio-demographic and health information, wore a wrist actigraph for 7 days, and completed Pittsburgh Sleep Quality Index, Center for Epidemiologic Studies - Depression Scale, and Epworth Sleepiness Scale. Identical data collection procedures were implemented again in the 2nd and 3rd trimester, with each data collection scheduled at least 8 weeks apart. We estimated unadjusted and multivariable adjusted odds ratios and 95% confidence intervals to evaluate various types of sleep disturbances at 1st trimester and risk of depression at follow-ups. 121 (59.3%) 1st trimester women had a sleep efficiency of < 85% by actigraphy, and 92 (45.1%) had Pittsburgh Sleep Quality Index global scores > 5 indicative of poor sleep quality. In multivariable adjusted models, 1st trimester objectively measured sleep efficiency < 85% was associated with 2.71-, 3.87-, and 5.27-fold increased odds having risk of depression at 2nd trimester, 3rd trimester, and both 2nd and 3rd trimesters, respectively. Healthy pregnant women experience both objective and subjective sleep disturbances during the early trimester, with a substantial proportion of them also having high depressive symptoms throughout the pregnancy. Objectively assessed poor sleep quality in the 1st trimester, but not self-reported characteristics of disturbed sleep, may play a role in the development of both elevated and persistent high depressive symptoms in pregnancy. Future studies using objective sleep measurements and clinical diagnostic interviews are warranted to examine whether an early intervention aiming at improving sleep may help reduce high depressive symptom risk and lower depression rate in women during pregnancy. Tweetable abstract : Objectively assessed poor sleep efficiency in the 1st trimester predicts both elevated and persistent high depressive symptoms in pregnancy. [ABSTRACT FROM AUTHOR]

Objective: To assess the effects of adenotonsillectomy (T&A) on ambulatory blood pressure (ABP) in childhood obstructive sleep apnea (OSA).Study Design: From 2012 to 2017, children aged 4-16 years with symptoms and polysomnography-diagnosed OSA (apnea-hypopnea index [AHI] >1) underwent T&A. PSG studies and 24-hour ABP monitoring were performed before and at 3 months after surgery.Results: In total, 159 children were enrolled (mean age, 7.8 ± 3.3 years; 72% male). T&A significantly reduced the AHI from 12.4 ± 15.9 events/hour to 2.7 ± 5.7 events/hour (P < .001). A decrease was observed in the children's overall diastolic blood pressure (65.1 ± 6.1 mm Hg to 63.8 ± 7.4 mm Hg, P = .04) after surgery. In subgroup analysis, 100 (63%) patients were classified as nonhypertensive, and 59 (37%) were classified as hypertensive. Linear mixed model analysis revealed that compared with the children without hypertension, those with hypertension had superior improvement in systolic and diastolic blood pressure during daytime and nighttime (all P values < .01). The ABP changes after surgery were not correlated with the AHI changes. Finally, preoperative hypertension was an independent risk factor of postoperative hypertension among these children (OR 3.66; 95% CI 1.70-7.86).Conclusions: Overall, in children with OSA, the 24-hour ABP change after T&A is small. However, among children with preoperative hypertension, there is significant BP improvement after T&A surgery. [ABSTRACT FROM AUTHOR]

Objective: To compare office blood pressure (BP) and 24-hour ambulatory BP (ABP) monitoring to facilitate the diagnosis and management of hypertension in children with obstructive sleep apnea (OSA).Study Design: Children aged 4-16 years with OSA-related symptoms were recruited from a tertiary referral medical center. All children underwent overnight polysomnography, office BP, and 24-hour ABP studies. Multiple linear regression analyses were applied to elucidate the association between the apnea-hypopnea index and BP. Correlation and consistency between office BP and 24-hour ABP were measured by Pearson correlation, intraclass correlation, and Bland-Altman analyses.Results: In the 163 children enrolled (mean age, 8.2 ± 3.3 years; 67% male). The prevalence of systolic hypertension at night was significantly higher in children with moderate-to-severe OSA than in those with primary snoring (44.9% vs 16.1%, P = .006). Pearson correlation and intraclass correlation analyses revealed associations between office BP and 24-hour BP, and Bland-Altman analysis indicated an agreement between office and 24-hour BP measurements. However, multiple linear regression analyses demonstrated that 24-hour BP (nighttime systolic BP and mean arterial pressure), unlike office BP, was independently associated with the apnea-hypopnea index, after adjustment for adiposity variables.Conclusions: Twenty-four-hour ABP is more strongly correlated with OSA in children, compared with office BP.

As a reversible thermochromic material, vanadium dioxide (VO 2 ) is a promising candidate for smart window applications. The trade-off between the integrated visible transmission ( T lum ) and the solar modulating ability (Δ T sol ), as well as the high phase transition temperature ( τ c ∼68 °C) are regarded as the main obstacle for practical applications of pure VO 2 nanomaterials. The combination of both high τ c reducing efficiency of W and improving T lum /Δ T sol properties of RE (rare earth: Eu, Tb), herein lies the purpose of RE/W-codoping to enhance the thermochromic performance. The RE/W-codoped VO 2 nanoparticles were synthesized under hydrothermal conditions, and exhibited grain size of less than 100 nm. The smart window which was fabricated by coating RE/W-codoped VO 2 nanoparticles onto glass, exhibits a thermochromic performance with a combination T lum = 40%, Δ T sol = 6.3%, τ c = 40.8 °C or T lum = 63%, Δ T sol = 3.6%, τ c = 31.9 °C, indicating the largely reduced absorption compared with the single W doping. Under the RE/W-codoping conditions, it was found that the ionic radius of the RE 3+ cations controlled the crystallinity of the VO 2 particles and the electron/hole carrier counteraction as well as the competition between the strain and the hole carrier played a vital role in modulating the τ c of the VO 2 products. The findings should be meaningful for investigating the codoping mechanisms for VO 2 nanomaterials. [ABSTRACT FROM AUTHOR]

Objective: Limited 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.Methods: Children 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.Results: In 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.Conclusion: The 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. [ABSTRACT FROM AUTHOR]

To assess the craniofacial morphology in children with sleep-disordered breathing (SDB) using nonradiation and readily accessible photogrammetry technique. Included children aged 3–18 years with SDB-related symptoms from April 2019 to February 2020 in a tertiary center. All participants underwent craniofacial photogrammetry and overnight polysomnography (PSG). Participants were stratified into 2 groups (obstructive sleep apnea [OSA] group: apnea-hypopnea index [AHI] ≥ 1 and non-OSA group: AHI <1). Craniofacial photogrammetry was performed to derive variables of craniofacial features in standardized frontal and profile views. The 2 groups were propensity score matched based on age, sex, and body mass index (BMI) percentiles. Associations between craniofacial feature variables and OSA (AHI ≥1) likelihood were examined using logistic regression test. intraclass correlation coefficient (ICC) was used to evaluate the intrarater and interrater reliability. In total, 58 children were enrolled for the analysis after matching. All 3 variables representing the mandibular plane angle in the profile view were increased in the OSA group (mego-tn: 34.85 ± 5.99 vs 31.65 ± 5.96°, odds ratio [OR]: 1.10, 95% CI:1.02 to 1.18, P =.01; tn-gogn: 28.65 ± 6.38 vs 25.91 ± 5.38°, OR: 1.08, 95% CI:1.02 to 1.15, P =.012; and gome-tsup: 26.71 ± 6.13 vs 22.20 ± 5.89°, OR: 1.13, 95% CI:1.04 to 1.23, P =.003). Craniofacial photogrammetry revealed increased mandibular inclination in children with OSA. A steep mandibular plane with craniofacial photogrammetry is considered a potential predictor of pediatric OSA. Further investigation with a large sample size is required to clarify the validity of photogrammetry in evaluating pediatric OSA. • OSA children present significantly increased mandibular plane angle through photogrammetry. • A steep mandibular plane is considered a characteristic craniofacial morphology in OSA children. • Profile view is easier than frontal view to manifest craniofacial characteristics. • Craniofacial photogrammetry is a novel technique that is easily accessible and radiation free. • For screening of pediatric SDB, craniofacial photogrammetry might be a potential tool readily accessible for clinicians.

Objective To assess short-term and long-term changes in quality of life after adenotonsillectomy (T&A) in children with obstructive sleep apnea (OSA). Materials and methods Children aged 2–18 years old were enrolled. All subjects had clinical symptoms, overnight polysomnography diagnosis of OSA, and received T&A as treatment. Caregivers were asked to complete the OSA-18 survey before surgery, within 6 months after surgery (short-term), and more than 6 months after surgery (long-term). Results A total of 114 children were included (mean age, 7.0 ± 3.5 years; 75% boys). The mean OSA-18 total score was 71.5 ± 16.0 before surgery. After surgery, the mean OSA-18 total score was significantly decreased in both the short-term (40.3 ± 12.2, p < 0.001) and the long-term (42.0 ± 13.7, p < 0.001). All five OSA-18 domains were also significantly decreased during short-term and long-term postoperative follow up ( p < 0.001). Short-term and long-term outcomes were compared. Mean OSA-18 total scores, sleep disturbance score, emotional distress score, daytime function score, and caregiver concerns score did not differ significantly between the short-term and long-term periods, while the physical symptom score was slightly higher in the long-term than the short-term period (9.7 ± 3.3 vs. 8.7 ± 3.0, p = 0.02). Additionally, the physical symptoms score was higher in the long-term period in the female ( p = 0.01), older age (>6 years) ( p = 0.03), and non-obese ( p = 0.04) subgroups. Conclusion T&A improves short-term and long-term quality of life in children with OSA. Nevertheless, caregivers observed children with aggravation of physical symptoms of quality of life during long-term follow up, especially in the female, older, and non-obese subgroups.
