BACKGROUND: Obstructive respiratory disorders, such as allergic rhinitis and asthma may impair sleep quality. The aim of this study is to validate the Children's Sleep Habits Questionnaire (CSHQ) for Greek children from 6 to 14 years of age. No validated tool has been developed so far to assess sleep disturbances in Greek school-aged children. METHODS: We examined the reliability and validity of the CSHQ in a sample of children with allergic rhinitis (AR) and a non-clinical population of parents of these children as a proxy measure of children's AR quality of life (QoL) as evaluated by the Pediatric Allergic Rhinitis Quality of Life (PedARQoL) questionnaire...

BACKGROUND: Symptom burden increases during pulmonary exacerbations of cystic fibrosis (CF), and patient-reported outcome measures (PROMs) are often used to evaluate symptoms as either primary or secondary outcomes. However, there is currently no guidance on the use of PROMs to assess symptom burden during pulmonary exacerbations. METHODS: A systematic literature search was conducted to identify PROMs measuring symptom experience, management, or influencing factors, which were developed for CF patients and had been used at least once during pulmonary exacerbations...

BACKGROUND: The mechanisms of the atopic march, characterized by a natural progression from food and cutaneous allergies to rhinitis and asthma, are still unknown. However, as several organs can be involved, chemokines and their receptors might be implicated in this process and may be instrumental factors. OBJECTIVES: We hypothesized that the T-cell gut-homing receptor CCR9 could be implicated in the evolution of allergic diseases. METHODS: We characterized the immune response and the role of CCR9 in a murine model combining food allergy to wheat gliadin and a model of acute airways inflammation in response to house dust mite...

The carotid body has recently emerged as a promising therapeutic target for treating cardiovascular disease, however the potential impact of carotid bodies removal on the dynamic cardiovascular responses to acute stressors such as exercise, hypoxia and hypercapnia in hypertension is an important safety consideration that has not been studied. We first validated a novel surgical approach to selectively resect the carotid bodies bilaterally (CBR) sparing the carotid sinus baroreflex. Second, we evaluated the impact of CBR on the cardiovascular responses to exercise, hypoxia and hypercapnia in the conscious, chronically instrumented spontaneously hypertensive (SH) rats...

Bronchoscopic examination has a key role in diagnosing or further specifying of a broad spectrum of respiratory diseases. Although classic bronchoscopy with its rigid instrumentation still upholds its position, the vast majority of procedures are performed with flexible bronchoscopes. Diagnostic possibilities are broadened by new technical findings and procedures, such as endobronchial ultrasonography, examination through autofluorescence, navigated bronchoscopy and others. The material for cytological, microbiological or other examinations can be sampled through a whole number of procedures using specialized instruments...

A seminatural, factorial-design experiment was used to quantify dynamics of the pathogen Mycoplasma agassizii and upper respiratory tract disease in the Mojave desert tortoise (Gopherus agassizii) over 2 years. Groups of initially healthy animals were separated into serologically positive (seropositive), seronegative, and artificially infected groups and paired into 23 pens. We found no evidence of long-term immune protection to M. agassizii or of immunological memory. Initially seronegative, healthy tortoises experienced an equal amount of disease when paired with other seronegative groups as when paired with seropositive and artificially infected groups-suggesting that recrudescence is as significant as transmission in introducing disease in individuals in this host-pathogen system...

Air sacs are an important component of the avian respiratory system, and corresponding structures also were crucial for the evolution of sauropod dinosaur gigantism. Inferring the presence of air sacs in fossils so far is restricted to bones preserving internal pneumatic cavities and foramina as osteological correlates. We here present bone histological correlates for air sacs as a new potential identification tool for these elements of the respiratory system. The analysis of several avian and non-avian dinosaur samples revealed delicate fibres in secondary trabecular and secondary endosteal bone that in the former case (birds) is known or in the latter (non-avian dinosaurs) assumed to have been in contact with air sacs, respectively...

OBJECTIVES: Traditional supraglottoplasty for pediatric laryngomalacia is most commonly conducted with either CO2 laser or cold steel instruments. While the procedure enjoys high success rates, serious complications such as excessive bleeding, supraglottic stenosis and aspiration can occur. Unilateral coblation supraglottoplasty may reduce this risk, but data on respiratory and swallowing outcomes are lacking. This study reports our experiences with unilateral coblation supraglottoplasty...

BACKGROUND: Infectious bovine rhinotracheitis virus (IBRV) is a major pathogen in cattle and has led to significant economic losses to the dairy industry worldwide, and therefore a more optimal method for the rapid diagnosis of IBRV infection is highly needed. In this study, we described the development of a lateral flow dipstrip (LFD) of isothermal recombinase polymerase amplification (RPA) method for rapid detection of IBRV. METHODS: Distinct regions were selected as a candidate target for designing the LFD-RPA primers and probes...

BACKGROUND: Respiratory distress is a common and distressing experience that strikes most critically ill patients with cardiopulmonary diseases. Now, most dyspnea assessment tools rely on patient's self-report. Only one instrument, the Respiratory Distress Observation Scale (RDOS), is valid for assessing respiratory distress when the patient cannot provide a dyspnea self-report. PURPOSE: The aims of this study were to develop the Chinese version of RDOS through two-way translation and examine its reliability and validity...

The respiratory system consists of an integrated network of organs and structures that primarily function for gas exchange. In mammals, oxygen and carbon dioxide are transmitted through a complex respiratory tract, consisting of the nasal passages, pharynx, larynx, and lung. Exposure to ambient air throughout the lifespan imposes vulnerability of the respiratory system to environmental challenges that can contribute toward development of disease. The importance of the respiratory system to human health is supported by statistics from the Centers for Disease Control and Prevention; in 2015, chronic lower respiratory diseases were the third leading cause of death in the United States...

Microarray technology can be useful for pathogen detection as it allows simultaneous interrogation of the presence or absence of a large number of genetic signatures. However, most microarray assays are labour-intensive and time-consuming to perform. This study describes the development and initial evaluation of a multiplex reverse transcription (RT)-PCR and novel accompanying automated electronic microarray assay for simultaneous detection and differentiation of seven important viruses that affect swine (foot-and-mouth disease virus [FMDV], swine vesicular disease virus [SVDV], vesicular exanthema of swine virus [VESV], African swine fever virus [ASFV], classical swine fever virus [CSFV], porcine respiratory and reproductive syndrome virus [PRRSV] and porcine circovirus type 2 [PCV2])...

AIMS: Chest compressions (CC) during cardiopulmonary resuscitation are not sufficiently effective in many circumstances. Mechanical CC could be more effective than manual CC, but there are no studies comparing both techniques in children. The objective of this study was to compare the effectiveness of manual and mechanical chest compressions with Thumper device in a pediatric cardiac arrest animal model. MATERIAL AND METHODS: An experimental model of asphyxial cardiac arrest (CA) in 50 piglets (mean weight 9...

Breathing parameters can be measured by motion capture systems by placing photo-reflective markers on the chest wall. A computational model is mandatory to compute the breathing volume and to calculate temporal and kinematical features by the gathered markers trajectories. Despite different methods based on different geometrical approaches can be adopted to compute volumes, no information about their differences in the respiratory evaluation are available. This study investigated the performances of four methods (conventional, prism-based, convex hull with boundary condition, based on Delaunay triangulation) using an optoelectronic motion capture system, on twelve healthy participants during 30 s of breathing...
