Heart failure (HF) is one of the most prevalent conditions worldwide and despite therapeutic advances, its prognosis remains poor. Among the multiple comorbidities in HF, sleep-disordered breathing (SDB) is frequent and worsens the prognosis. Preliminary observational studies suggested that treatment of SDB could modify the prognosis of HF, and the issue has gained importance in recent years. The diagnosis of SDB is expensive, slow and suboptimal, and there is thus a need for screening devices that are easier to use and validated in this population...

OBJECTIVE: This study aimed to determine whether overweight and obesity increased the detrimental effects of pediatric sleep-disordered breathing (SDB) on cognition, behavior, mood, and quality of life. METHODS: Children and adolescents (8-16 years) with clinically diagnosed SDB were categorized into two groups: healthy weight (Body Mass Index (BMI) z-score <1.04, N = 11) and overweight/obese (BMI z-score ≥ 1.04, N = 10). Age-matched healthy weight, non-snoring controls (N = 25) were recruited from the community...

Colored waterborne polyurethanes have been widely used in paintings, leathers, textiles, and coatings. Here, a series of black waterborne polyurethanes (WPUs) with different ratios of black dye, Sudan Black B (SDB), were prepared by step-growth polymerization. WPU emulsions as obtained exhibit low particle sizes and remarkable storage stability at the same time. At different dye loadings, essential structural, statistical and thermal properties are characterized. FTIR (fourier transform infrared) spectra indicate that SDB is covalently linked into waterborne polyurethane chains...

PURPOSE OF REVIEW: Allergic rhinitis and nonallergic rhinitis (NAR) are common disorders, which have been considered as potential risk factors for obstructive sleep apnea (OSA). This review summarizes the proposed underlying pathophysiological mechanisms to provide a better understanding of the relationship between these conditions. RECENT FINDINGS: In adults, allergic rhinitis and NAR may be considered as symptoms potentiating, rather than risk potentiating factors in the pathophysiology of OSA, whereas in children, these are considered to be independent predictors for sleep-disordered breathing (SDB) and failure of adeno-tonsillectomy, the recommended first-line therapy for children with OSA...

There is increasing prevalence of both asthma and obesity in children globally in recent years. Various epidemiological studies link obesity as a risk factor for asthma and suggest a possible causal association. Obesity asthma phenotype is considered as distinct in view of greater severity and poor asthma control. Various mechanisms underlying this phenotype have been suggested including mechanical effects of obesity and systemic inflammation, but still the exact mechanism is unclear. Also, the comorbidities like gastroesophageal reflux disease (GERD) and sleep disordered breathing (SDB) lead to inflammation in airways and contribute to asthma obesity association...

STUDY OBJECTIVES: Sleep disorders are frequent in stroke patients. The prevalence of sleep-disordered breathing (SDB), excessive daytime sleepiness (EDS), and restless legs syndrome (RLS) among stroke survivors is up to 91%, 72%, and 15%, respectively. Although the relationship between EDS and SDB is well described, there are insufficient data regarding the association of EDS with RLS. The aim of this study was to explore the association between EDS, SDB, and RLS in acute ischemic stroke...

INTRODUCTION: Bardet-Biedl Syndrome (BBS) is an autosomal recessive ciliopathy, and obesity is among its defining characteristics. Consequently, the incidence of sleep disordered breathing (SDB) in this population is expected to be high. Due to its relative rarity, the nature of SDB in this population is poorly described. The objective of this study was to review a single institutional experience in the assessment and management of SDB in patients with BBS. METHODS: Retrospective chart review of tertiary care, academic pediatric hospital...

Tinnitus and sleep are closely related. One of the most important aspects of tinnitus is its association with sleep disturbance. According to the literature, up to 71% of patients with tinnitus report sleep problems (1); furthermore, insomnia is also associated with more distressing tinnitus (2). Conversely, sleep disturbance was proposed as one of the causes of chronic tinnitus (3). The relationship of tinnitus with sleep-disordered breathing (SDB) and obstructive sleep apnea (OSAS) has rarely been mentioned (4)...

PURPOSE: Sleep disordered breathing (SDB) is highly prevalent in older adults. Increasing evidence links SDB to the risk of dementia, mediated via a number of pathways, some of which may be attenuated by low-dose aspirin. This study will evaluate, in a healthy older cohort, the prospective relationship between SDB and cognitive function, changes in retinal and cerebral microvasculature, and determine whether low-dose aspirin ameliorates the effects of SDB on these outcomes over 3years...

Seed priming is to expose seeds to specific compounds to enhance seed germination. Few studies of plant immune activation through seed priming have been conducted. Here, we introduce an emerging technology that combines seed priming with elicitation of plant immunity using biologically active compounds. This technology is named 'seed defense biopriming' (SDB). We prepared heat-stable metabolites from 1,825 root-associated Bacillus spp. isolated from the rhizosphere in South Korea. These preparations were tested for their ability to induce SDB in cucumber and pepper seeds and trigger plant immunity...

Objective: Multiple sleep onset rapid eye movement (R) periods (SOREMPs) and a mean sleep latency ≤8min on the multiple sleep latency test (MSLT) are diagnostic criteria of narcolepsy (NC), but occur also in other conditions with increased sleep pressure, including insufficient sleep syndrome (ISS), sleep disordered breathing (SDB) or Parkinson's disease (PD). These false positives are common, may create diagnostic uncertainty, and highlight the need for complementary MSLT measures with high specificity for narcolepsy...

Emerging literature suggests that sleep-disordered breathing (SDB) worsens over the course of pregnancy and is associated with adverse maternal and fetal outcomes. Earlier studies, using mainly snoring as a surrogate marker for SDB, have shown an increase in the prevalence of SDB during pregnancy compared with that in the pregravid state. More recently, prospective observational studies in which the investigators ascertained SDB by using complete polysomnography have shown a prevalence ranging from approximately 17% to 45% in the third trimester...

BACKGROUND: There are limited data on the effect of bronchopulmonary dysplasia (BPD) on sleep disordered breathing (SDB). We hypothesized that both the severity of prematurity and BPD would increase the likelihood of SDB in early childhood. Our secondary aim was to evaluate the association of demographic factors on the development of SDB. METHODS: This is a retrospective study of patient factors and overnight polysomnogram (PSG) data of children enrolled in our BPD registry between 2008 and 2015...
