BACKGROUND: The patterns of mandibular movements (MM) during sleep can be used to identify increased respiratory effort periodic large-amplitude MM (LPM), and cortical arousals associated with "sharp" large-amplitude MM (SPM). We hypothesized that Cheyne Stokes breathing (CSB) may be identified by periodic abnormal MM patterns. The present study aims to evaluate prospectively the concordance between CSB detected by periodic MM and polysomnography (PSG) as gold-standard.

The low-fermentable oligo-, di-, and monosaccharide and polyol (FODMAP) diet is a 2-phased intervention, with strict reduction of all slowly absorbed or indigestible short-chain carbohydrates (ie, FODMAPs) followed by reintroduction of specific FODMAPs according to tolerance. The efficacy of the elimination phase of the FODMAP diet is well established, but the success of maintaining this diet has been shown in only a few observational studies. How the efficacy of the low-FODMAP diet compares with that of other therapies has received limited attention, but recent studies have shown this diet to be comparable or superior to diets that address eating style and choice of food as well as to gut hypnotherapy...

Obstructive sleep apnea (OSA) is a disorder characterized by a cessation of breathing during sleep, leading to poor sleep patterns and daytime somnolence. Daytime somnolence is of particular concern for commercial vehicle drivers, whose crash risk increases 50% with untreated OSA. The process of diagnosing and treating OSA in commercial drivers begins with effective and consistent screening. Therefore, the researchers screened drivers with both the STOP-Bang Questionnaire and the Obstructive Sleep Apnea Evaluation Worksheet (OSAEW) and compared the two tools...

PURPOSE: Hyperpolarized (129) Xe magnetic resonance imaging (MRI) using Dixon-based decomposition enables single-breath imaging of (129) Xe in the airspaces, interstitial barrier tissues, and red blood cells (RBCs). However, methods to quantitatively visualize information from these images of pulmonary gas transfer are lacking. Here, we introduce a novel method to transform these data into quantitative maps of pulmonary ventilation, and (129) Xe gas transfer to barrier and RBC compartments...

OBJECTIVE: The psychometric properties of the Sleep Disturbance Scale for Children (SDSC) have been shown to be accurate, even when translated into several languages. The aim of the present study was to translate, adapt, and validate the SDSC for a French-speaking population. METHODS: After forward- and back-translation, the tool was further translated and adapted into the French language. It was then pretested in terms of clarity on 33 French-speaking parents. Pretesting demonstrated that the questionnaire was well understood, indicating good clarity...

We used a remotely monitored non-contact biosensor (SleepMinder™) to measure breathing during sleep (SDB) in a prospective study of 91 patients with stable class II to IV heart failure (HF). The device algorithm measures a surrogate of the traditional apnoea/hypopnoea index (AHI) measured in polysomnographic sleep studies. Data was transmitted daily to a central monitoring centre and analysed in consecutive 2-week blocks. A total of 37 465 nights over 3-24 months was analysed. An AHI of >15/h was considered clinically significant...

BACKGROUND AND PURPOSE: In 1989, the Cleft Palate-Craniofacial Journal published the first randomized prospective cleft surgery study, comparing the Kriens intravelar veloplasty (IVV) with a non-IVV 2-flap repair. Results in that and follow-up publications yielded no difference between the 2 groups for need for secondary velopharyngeal management. The subjects have now reached adulthood. This study was designed to ask: Is there any difference between the groups in the outcomes that multidisciplinary team care addresses: speech intelligibility, facial growth, breathing while awake and asleep, attainment of education, and long-term socioeconomic status? METHODS: Enrollees from the original published study were invited to participate in a survey...

Between 7-18 million Americans suffer from sleep disordered breathing (SDB), including those who suffer from obstructive sleep apnea (OSA). Despite this high prevalence and burden of OSA, existing diagnostic techniques remain impractical for widespread screening. In this study, we introduce a new model for OSA screening and describe an at-home wearable sleep mask (named ARAM) that can robustly track the wearers' sleep patterns. This monitoring is achieved using select sensors that enable screening and monitoring in a form-factor that can be easily self-instrumented...

Forces involved in breathing-which effectively pull in air-are the diaphragmatic, intercostal, spine, and neck muscles. Equally important is the bulbar musculature maintaining the architecture of a patent airway conduit and abdominal wall and internal intercostal muscles providing cough. Acute injury along a neural trajectory from brainstem to muscle will impair the coordinated interaction between these muscle groups. Acutely failing respiratory mechanics can be caused by central and peripheral lesions. In central lesions, the key lesion is in the nucleus ambiguus innervating the dilator muscles of the soft palate, pharynx, and larynx, but abnormal respiratory mechanics rarely coincide with abnormalities of the respiratory pattern generator...

A recently discovered neurodevelopmental disorder caused by the mutation of the cyclin-dependent kinase-like 5 gene (CDKL5) entails complex autistic-like behaviours similar to Rett syndrome, but its impact upon physiological functions remains largely unexplored. Sleep-disordered breathing is common and potentially life-threatening in patients with Rett syndrome; however, evidence is limited in children with CDKL5 disorder, and is lacking altogether in adults. The aim of this study was to test whether the breathing pattern during sleep differs between adult Cdkl5 knockout (Cdkl5-KO) and wild-type (WT) mice...

Muscular dystrophy is a group of inherited myopathies characterised by progressive skeletal muscle wasting, including of the respiratory muscles. Respiratory failure, i.e. when the respiratory system fails in its gas exchange functions, is a common feature in muscular dystrophy, being the main cause of death, and it is a consequence of lung failure, pump failure or a combination of the two. The former is due to recurrent aspiration, the latter to progressive weakness of respiratory muscles and an increase in the load against which they must contract...

REVIEW
A Balofsky, J George, P Papadakos
Neuropulmonology refers to the complex interconnection between the central nervous system and the respiratory system. Neurologic injury includes traumatic brain injury, hemorrhage, stroke, and seizures, and in each there are far-reaching effects that can result in pulmonary dysfunction. Systemic changes can induce impairment of pulmonary function due to changes in the core structure and function of the lung. The conditions and disorders that often occur in these patients include aspiration pneumonia, neurogenic pulmonary edema, and acute respiratory distress syndrome, but also several abnormal respiratory patterns and sleep-disordered breathing...

PURPOSE: The purpose of this study was to use non-EEG PSG signals to estimate TST in order to diagnose SDB with a greater sensitivity than type 3 device methodology that relies on TRT. METHODS: Movement patterns were obtained from the thoracoabdominal signals of adult PSG recordings (n = 60) in the laboratory and the home. Parameters obtained allowed, with 95% certainty, identification of sleep and wake based on the duration of movements and quiescent time (Qd)...

A major limitation in the study of sleep breathing disorders in mouse models of pathology is the need to combine whole-body plethysmography (WBP) to measure respiration with electroencephalography/electromyography (EEG/EMG) to discriminate wake-sleep states. However, murine wake-sleep states may be discriminated from breathing and body movements registered by the WBP signal alone. Our goal was to compare the EEG/EMG-based and the WBP-based scoring of wake-sleep states of mice, and provide formal guidelines for the latter...

BACKGROUND AND OBJECTIVE: Dysfunctional breathing (DB) is a respiratory disorder, which involves a pattern of breathing too deeply, too superficially and/or too rapidly. In asthma patients, DB may lead to an overestimation of the severity of asthma symptoms, and hence potentially to overtreatment. However, it is not known to which degree DB may affect estimates of asthma control, in a specialist clinical setting. METHODS: The MAPOut-study examined all patients referred consecutively over a 12-months period for specialist assessment of asthma at the Respiratory Outpatient Clinic at Bispebjerg Hospital in Copenhagen...

BACKGROUND: Dyspnea is a common symptom affecting as many as 25% of patients seen in the ambulatory setting. It can arise from many different underlying conditions and is sometimes a manifestation of a life-threatening disease. METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed, and on pertinent guidelines. RESULTS: The term dyspnea refers to a wide variety of subjective perceptions, some of which can be influenced by the patient's emotional state...
