Objectives: Precision medicine for obstructive sleep apnea (OSA) requires non-invasive estimates of each patient's pathophysiological "traits". Here we provide the first, automated technique to quantify the respiratory arousal threshold-defined as the level of ventilatory drive triggering arousal from sleep-using diagnostic polysomnographic signals in patients with OSA. Methods: Ventilatory drive preceding clinically-scored arousals was estimated from polysomnographic studies by fitting a respiratory control model (Terrill P et al...

Human rhinoviruses (HRVs) are the commonest cause of the common cold. While less pathogenic compared to other respiratory viruses, it is frequently associated with exacerbation of chronic respiratory diseases such as rhinosinusitis and asthma exacerbation. Currently, there are limited studies on HRV infection of nasal epithelial cells despite being the first site of viral contact, immune initiation, and airway inter-connectivity. Hence, we established a model of HRV infection of in vitro differentiated human nasal epithelial cells (hNECs) derived from multiple individuals...

The impact of low pathogenic influenza viruses such as subtype H9N2, which infect the respiratory and the gastrointestinal tracts of chickens, on microbial composition are not known. Twenty day-old specific pathogen free chickens were assigned to two treatment groups, control (Uninfected) and H9N2-infected (challenged via the oral-nasal route). Fecal genomic DNA was extracted, and the V3-V4 regions of the 16S rRNA gene was sequenced using the Illumina Miseq® platform. Sequences were curated using Mothur as described in the MiSeq SOP...

Background: In 2007, Illinois became the first state in the United States to mandate active surveillance of methicillin-resistant Staphylococcus aureus (MRSA). The Illinois law applies to intensive care unit (ICU) patients; contact precautions are required for patients found to be MRSA-colonized. However, the effectiveness of a legislated "search and isolate" approach to reduce MRSA burden among critically ill patients is uncertain. We evaluated whether the prevalence of MRSA colonization declined in the 5 years after the start of mandatory active surveillance...

BACKGROUND: While Eustachian tube dysfunction (ETD) is a known comorbidity of chronic rhinosinusitis (CRS), the prevalence of ETD symptoms in the CRS population is poorly understood. We sought to determine the cross-sectional prevalence of ETD in patients with CRS using the validated Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and to correlate ETDQ-7 scores with 22-item Sino-Nasal Outcome Test (SNOT-22) scores, endoscopy scores, and computed tomography (CT) scores. METHODS: A total of 101 patients with confirmed CRS completed the ETDQ-7 and SNOT-22 at their initial visit to our rhinology clinic...

BACKGROUND: There has been little investigation regarding air quality and rhinitis in the pathophysiology of upper airway disease. In this study, we assessed the impact of inhalant pollutants (particulate matter 2.5 [PM2.5 ] and black carbon [BC]) on allergic rhinitis and chronic rhinosinusitis (CRS) disease severity. METHODS: CRS patients with nasal polyps (CRSwNP) and without polyps (CRSsNP) were identified. Spatial modeling from pollutant monitoring sites was used to estimate exposures for patients meeting the inclusion criteria (total, n = 125; CRSsNP, n = 67; CRSsNP, n = 58)...

An intraosseous lipoma is a rare histologic variant of lipoma, accounting for only 0.1% of all primary bone tumors. This may not be the actual incidence because most of these lesions are frequently asymptomatic, but imaging modalities, such as computed tomography or magnetic resonance imaging (MRI) seem to have increased the detection rate. Lipoma occasionally undergoes osseous metaplasia and becomes an osseous lipoma. Although there are numerous papers discussing intraosseous lipoma and some authors have tried to differentiate lipomas from osseous lipomas, there is still a great deal of confusion with regard to characteristic radiologic features and the use of terms...

OBJECTIVE: Pneumococcal infection caused by Streptococcus pneumoniae is a major upper respiratory tract disease that causes severe illness and mortality. Therefore, it is important to develop safe and effective vaccines to prevent pneumococcal infections. The goal of the study was to investigate the effectiveness of transcutaneous immunization (TCI) for induction of pneumococcal surface protein A (PspA) responses in the upper respiratory tract. METHODS: C57BL/6 mice were transcutaneously immunized with 1 μg of PspA and 2 μg of cholera toxin (CT) six times at weekly intervals and compared with transcutaneously treated controls (PBS alone/PspA alone/CT alone)...

The host defense system with lysozyme and secretory phospholipase A2 (sPLA2) was immunohistochemically investigated in rat respiratory tract under healthy conditions. In the nasal epithelium, a large number of non-ciliated and non-microvillous cells (NC) and a small number of goblet cells (GC) were immunopositive for lysozyme and sPLA2. A few acinar cells and almost all epithelial cells of intercalated ducts were immunopositive for both bactericidal substances in the nasal glands. In the laryngeal and tracheal epithelia, few NC and GC were immunopositive for both bactericidal substances...

In the Alps, traditional dairy farms are small-scale operations where vertical transhumance from valley indoor housing systems to highland pasture-based systems is still practiced in summer. Vertical transhumance implies a substantial change of environment, available resources, and management practices from one season to another. In such systems, animal-based welfare measures need to be monitored throughout the year to capture the variation of welfare outcomes, based on which targeted welfare management plans can be implemented...

INTRODUCTION: Adenoidectomy is one of the most commonly performed pediatric operations worldwide. There are a proportion of children who require revision adenoidectomy. Yet there is little in the literature about the incidence, associated factors and etiology of adenoidal regrowth. The aim of this retrospective cohort study was to determine incidence and factors associated with revision adenoidectomy. METHODS: An extraction of all hospital morbidity records belonging to patients under the age of 18 years who underwent one or more adenoidectomy procedures (with or without tonsillectomy) between January 1, 2000 and June 2016 at a tertiary care children's hospital was performed...

Chronic rhinosinusitis (CRS) is a well-known disease encountered in the department of otorhinolaryngology, yet little is known about its pathogenesis. Autophagy, a lysosome-dependent degradation process, has been reported to be involved in the process of many chronic inflammatory diseases. Here we tried to evaluate the function of autophagy in CRS as well as explore the related mechanisms. We first stained light chain 3B (LC3B) with immunohistochemistry in uncinate tissues (UT) from patients with and without CRS and found that its expression was up-regulated in CRS patients...
