Monitoring of cardiopulmonary activity is a challenge when attempted under adverse conditions, including different sleeping postures, environmental settings, and an unclear region of interest (ROI). This study proposes an efficient remote imaging system based on a Microsoft Kinect v2 sensor for the observation of cardiopulmonary-signal-and-detection-related abnormal cardiopulmonary events (e.g., tachycardia, bradycardia, tachypnea, bradypnea, and central apnoea) in many possible sleeping postures within varying environmental settings including in total darkness and whether the subject is covered by a blanket or not...

Morphine and other opioids cause respiratory depression in high doses and lower the ventilatory responses to hypoxia and hypercapnia in mammals. Recent studies indicate that turtles respond similarly, but although they are used routinely for post-surgical analgesia, little is known about the physiological effects of opioids in reptiles. We therefore investigated the effects of morphine (10 and 20 mg kg-1 ) on gas exchange and ventilation in six dwarf caiman (Paleosuchus palpebrosus) using pneumotachography in a crossover design...

AIM: Less invasive surfactant administration (LISA) can avoid tracheal intubation for neonatal respiratory distress syndrome, but can be painful because it requires laryngoscopy. The aim of this study was to assess the efficacy and tolerance of intravenous atropine plus ketamine administration before LISA. METHODS: We conducted a prospective observational study of all premature infants hospitalised in our French neonatal intensive care unit treated with LISA between March 2015 and March 2016...

BACKGROUND: Periodic breathing and short apnoeas are common in infants, particularly those born preterm, but are thought to be benign. The aim of our study was to assess the incidence and impact of periodic breathing and apnoea on heart rate, oxygen saturation and brain tissue oxygenation index (TOI) in infants born at term and preterm over the first 6 months after term equivalent age. STUDY DESIGN: 19 infants born at (38-42 weeks gestational age) and 24 preterm infants (born at 27-36 weeks gestational age) were studied at 2-4 weeks, 2-3 months and 5-6 months post-term corrected age during sleep...

OBJECTIVES: Originally developed as a paper questionnaire, the electronic Epworth Sleepiness Scale (ESS) is widely used in sleep clinics and sleep population research. Despite potential differences between computer-based and conventional questionnaire delivery, studies have not evaluated the agreement between electronic and paper versions of the ESS. Given the widespread use of the ESS, a bias between results would present considerable data concerns. Thus, the aim of this study was to examine agreement between electronic and paper ESS responses in obstructive sleep apnoea (OSA)...

Chronic intermittent hypoxia (ChIH) is a dominant feature of obstructive sleep apnoea (OSA) and is associated to metabolic alterations and oxidative stress (OS). Although management of OSA is well established, the research of new biomarkers that are independent of confounding factors remains necessary to improve the early detection of comorbidity and therapeutic follow-up. In this study, the urinary metabonomic profile associated to intermittent hypoxia was evaluated in a mouse model. When exposed to intermittent hypoxia, animals showed a significant alteration in energy metabolism towards anaerobic pathways and signs of OS imbalance...

The goal of this study was to assess the relationship between the severity of OSA and the levels of carcinogenesis- and tumour growth-related biomarkers, in patients with cutaneous melanoma (CM).This multicentre observational study included patients who were newly diagnosed with melanoma. The patients were classified as non-OSA (apnoea-hypopnoea index (AHI); 0-5 events/h), mild-OSA (AHI; 5-15 events/h), and moderate to severe OSA (AHI>15 events/h). Enzyme-linked immunosorbent assays (ELISAs) were performed to analyse the serum levels of hypoxia- and tumour adhesion-related biomarkers (VEGF, IL8, ICAM-1, VCAM-1), and markers of tumour aggressiveness (S100B, MIA)...

Obstructive sleep apnoea (OSA) characterized by intermittent hypoxia (IH) is closely associated with cardiovascular diseases. IH confers cardiac injury via accelerating cardiomyocyte apoptosis, whereas the underlying mechanism has remained largely enigmatic. This study aimed to explore the potential mechanisms involved in the IH-induced cardiac damage performed with the IH-exposed cell and animal models and to investigate the protective effects of haemin, a potent haeme oxygenase-1 (HO-1) activator, on the cardiac injury induced by IH...

A patent foramen ovale (PFO) is not to be considered a disease as it is present in about 25 % of people. Yet, it is the prime reason for paradoxical embolism that can cause serious problems, such as death, stroke, myocardial infarction, and peripheral ischemia. The frequency of such events is probably underestimated as other causes tend to be blamed for them. Device PFO closure can be easily accomplished as outpatient procedure with minimal discomfort and risk and it has been referred to as mechanical vaccination...

BACKGROUND: Retinopathy of prematurity (ROP) is a vision-threatening disease of preterm neonates. The use of beta-adrenergic blocking agents (beta-blockers), which modulate the vasoproliferative retinal process, may reduce the progression of ROP or even reverse established ROP. OBJECTIVES: To determine the effect of beta-blockers on short-term structural outcomes, long-term functional outcomes, and the need for additional treatment, when used either as prophylaxis in preterm infants without ROP, stage 1 ROP (zone I), or stage 2 ROP (zone II) without plus disease or as treatment in preterm infants with at least prethreshold ROP...

PURPOSE: Sleep apnoea syndrome (SAS) is often associated with glaucoma, and intermittent hypoxia, present in SAS, can contribute to glaucoma pathogenesis. However, the relationships between SAS, high systemic oxidative stress and the speed of glaucoma progression are unclear. Thus, we investigated these relationships in glaucoma patients with and without SAS. METHODS: Peripheral blood samples were collected from 166 eyes of 166 Japanese patients: 42 controls, 109 open-angle glaucoma (OAG) patients without SAS and 15 OAG patients with SAS...

We aimed to assess the prevalence of suicidal ideation and to examine the relationships between obstructive sleep apnoea severity, sleep-related problems, social support and suicidal ideation in obstructive sleep apnoea patients. We included 149 patients (68% male; mean age, 48.99 ± 9.57 years) with diagnosed obstructive sleep apnoea (Apnoea-Hypopnoea Index ⩾5) based on full-night polysomnography. The prevalence of suicidal ideation among obstructive sleep apnoea patients was 20.1 per cent. Structural equation modelling showed that suicidal ideation in obstructive sleep apnoea was strongly related to poor sleep quality and high fatigue levels...

In this study, the hypercapnic ventilatory response (HCVR) was measured, defined as the ventilation response to carbon dioxide tension ( P CO2 ). We investigated which method, rebreathing or steady-state, is most suitable for measurement of the HCVR in healthy subjects, primarily based on reproducibility. Secondary outcome parameters were subject experience and duration. 20 healthy adults performed a rebreathing and steady-state HCVR measurement on two separate days. Subject experience was assessed using numeric rating scales (NRS)...

Background: Airway management is a core clinical skill in anaesthesia. Pre-oxygenation prior to induction of anaesthesia is a standard practice to prevent desaturation. Apnoeic oxygenation in adults is effective and prolongs the time to desaturation. The effectiveness of apnoeic oxygenation in the adult is well documented; however, evidence in the paediatric is lacking. Therefore, the aim of this study was to investigate the effectiveness of apnoeic oxygenation during airway management in children...

Introduction: There is a worldwide increase in the prevalence of obesity among the adolescent population in India from 16.3% in 2001 to 19.3% in 2010. Recent evidence suggests that bariatric surgery leads to resolution of comorbidities and associated long-term complications in adolescent patients with morbid obesity. Aim: The aim of this study is to determine the impact of bariatric surgery on the weight loss and comorbidities of morbidly obese adolescents. Materials and Methods: A retrospective review of the data of 10 adolescent patients, who underwent Laparoscopic Sleeve Gastrectomy at our institute (tertiary care hospital), from July 2009 to July 2016 was carried out...

Nalmefene, an opioid antagonist, has recently been approved for the treatment of alcohol dependence. We describe here the first case of a 52-year-old woman who developed a severe central sleep apnoea (CSA) 5 months after initiation of nalmefene. Scoring of ventilation during sleep recording revealed an apnoea-hypopnoea index of 67/h with 98.7% of central events and an apnoea index of 65/h. Nalmefene was withdrawn and a new polysomnography was performed which concluded that CSA has disappeared. Pathophysiology is still unclear but could involve the κ-opioid receptors...
