BACKGROUND: Recent evidence has shown that adaptive servo-ventilation (ASV) is contraindicated in patients with predominant central sleep apnea (CSA) and reduced left ventricular ejection fraction (LVEF ≤45%). The objective of this study was to assess the clinical usage of ASV in patients at the time-point of the release of a safety warning by type of SDB, breathing pattern and LVEF. METHODS: Patients of a cardiac and a respirology sleep center, both in Germany, who received ASV therapy were contacted between May and October 2015...

The environment plays a critical role in shaping development and function of the brain. Stress, especially when experienced early in life, can interfere with these processes. In the context of respiratory control, perinatal stress can therefore alter the ability to achieve the "fine-tuning" necessary for proper detection of chemosensory stimuli and production of an adequate motor (respiratory) command. Depending on the timing, intensity, and duration, the detrimental consequences of perinatal exposure to adverse conditions on the respiratory network become manifest at various life stages and can persist into adulthood...

Hydrogen sulfide exists widely in mammalian tissues and plays a vital role in physiological and pathophysiological processes. However, striking differences with orders of magnitude were observed for the detected hydrogen sulfide concentrations in biological matrices among different measurements in literature, which lead to the uncertainty for examination the biological relevance of hydrogen sulfide. Here, we developed and validated a liquid chromatography- mass spectrometry (LC-MS/MS) method for the determination of hydrogen sulfide in various biological matrices by determination of a derivative of hydrogen sulfide and monobromobimane named sulfide dibimane (SDB)...

BACKGROUND: The surgical excision of anatomic obstructions such as adenoids, palatine or lingual tonsils are commonly performed in children with sleep disordered breathing (SDB). Imaging studies measuring airway changes post-surgery in the SDB pediatric population are scarce, rarely addresses the nasal cavity, and are based on global measures (e.g. volume) that do not represent the complexity of the upper airway anatomy. The purpose of this pilot is to test the feasibility in using cone beam CT (CBCT) to analyze the nasal and pharyngeal airway space post-surgery using meaningful methods of analyses, and correlating imaging findings with clinical outcomes in children with SDB symptoms and maxillary-mandibular disproportion...

This review aims to explain the inevitable imbalance between respiratory load, drive, and muscular force that occurs in the natural aging of Duchenne muscular dystrophy and that predisposes these patients to sleep disordered breathing (SDB). In DMD, SDB is characterized by oxygen desaturation, apneas, hypercapnia, and hypoventilation during sleep and ultimately develops into respiratory failure during wakefulness. It can be present in all age groups. Young patients risk obstructive apneas because of weight gain, secondary to progressive physical inactivity and prolonged corticosteroid therapy; older patients hypoventilate and desaturate because of respiratory muscle weakness, in particular the diaphragm...

INTRODUCTION: Sleep disordered breathing (SDB) symptoms are associated with increased rates of opioid-induced respiratory depression as well as enhanced nociception. Consequently, practitioners often withhold or administer lower intraoperative doses of opioids out of concern for postoperative respiratory depression. Therefore, SDB may be a critical determinant of analgesic requirement in the post-anesthesia care unit (PACU). We investigated whether preoperative SDB classification was independently associated with need for PACU analgesic intervention in a cross-sectional sample of 985 children who underwent elective, painful ambulatory surgical procedures...

PURPOSE: Sleep-disordered breathing (SDB) is highly prevalent in patients with heart failure and reduced left ventricular ejection fraction (HF-REF). SDB is classified as predominant obstructive (OSA) or central (CSA) and may alter sleep duration, sleep quality, and quality of life. This study describes sleep quality and duration in well-characterized cohorts of these patients. METHODS: Two hundred fifty consecutive patients with HF-REF (NYHA class ≥II, ejection fraction ≤45%) underwent cardiac and pulmonary examination, plus full attended in-hospital overnight polysomnography (PSG)...

Sleep disordered breathing (SDB) is common in patients with coronary disease, but its impact on post-operative recovery after coronary artery bypass graft surgery (CABG) is unclear. We therefore determined the effects of SDB on post-operative outcome after elective CABG.In this prospective two-centre study, 219 patients due to receive elective CABG underwent cardiorespiratory polygraphy for SDB prior to surgery and were monitored for post-operative complications. The primary end-point was a composite of 30-day mortality or major post-operative complications (cardiac, respiratory, surgical, infectious, acute renal failure or stroke)...

BACKGROUND: People with Down syndrome (DS) often have sleep-disordered breathing (SDB). Unusual sleep postures, such as leaning forward and sitting, are observed in people with DS. This study aimed to clarify the prevalence of unusual sleep postures and their relationships with SDB-related symptoms (SDB-RSs), such as snoring, witnessed apnoea, nocturnal awakening and excessive daytime sleepiness. METHODS: A questionnaire, including demographic characteristics and the presence of unusual sleep postures, as well as SDB-RSs, was completed by 1149 parents of people with DS from Japan...

INTRODUCTION: Both types of sleep-disordered breathing (SDB), obstructive and central sleep apnoea (OSA and CSA, respectively), are common in patients with heart failure and reduced ejection fraction (HFrEF). In such patients, SDB is associated with increased cardiovascular morbidity and mortality but it remains uncertain whether treating SDB by adaptive servo-ventilation (ASV) in such patients reduces morbidity and mortality. AIM: ADVENT-HF is designed to assess the effects of treating SDB with ASV on morbidity and mortality in patients with HFrEF...

Sourdough fermentation has been increasingly used worldwide, in accordance with the demand of consumers for tasty, natural and healthy food. The high diversity of lactic acid bacteria (LAB) and yeast species, detected in sourdoughs all over the world, may affect nutritional, organoleptic and technological traits of leavened baked goods. A wide regional variety of traditional sourdough breads, over 200 types, has been recorded in Italy, including special types selected as worthy of either Protected Geographical Indication (PGI) or Protected Designation of Origin (PDO), whose sourdough microbiota has been functionally and molecularly characterized...

Rationale: Current scoring criteria of non-apneic events (ie, hypopnea) require the presence of oxyhemoglobin desaturation and/or arousal. However, other sleep study parameters may help to identify abnormal respiratory events (REs) and assist in making more accurate diagnosis. Objectives: To investigate whether non-apneic REs without desaturation or cortical arousal are associated with respiratory and cardiac consequences. Methods: Thirteen participants with sleep disturbances (snoring and/or excessive day time sleepiness), were screened using attended in laboratory polysomnography (PSG) while monitoring pressure and airflow via a nasal mask with an attached pneumotach...

INTRODUCTION: Despite the high prevalence of sleep-disordered breathing (SDB) and the significant health consequences associated with untreated disease, access to diagnosis and treatment remains a challenge. Even patients with severe SDB (severe obstructive sleep apnoea or hypoventilation), who are at particularly high risk of adverse health effects, are subject to long delays. Previous research has demonstrated that, within a sleep clinic, management by alternative care providers (ACPs) is effective for patients with milder forms of SDB...

Solanesol is a non-cyclic terpene alcohol composed of nine isoprene units that mainly accumulates in solanaceous plants. Solanesol plays an important role in the interactions between plants and environmental factors such as pathogen infections and moderate-to-high temperatures. Additionally, it is a key intermediate for the pharmaceutical synthesis of ubiquinone-based drugs such as coenzyme Q10 and vitamin K2, and anti-cancer agent synergizers such as N-solanesyl-N,N'-bis(3,4-dimethoxybenzyl) ethylenediamine (SDB)...

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...
