Nasal epithelial cells from very preterm infants have a functional defect in their ability to repair beyond the first year of life, and failed repair may be associated with antenatal steroid exposure https//bit.ly/39OFJs7. Reduction of COL4A3, one of the six isoforms of collagen 4, in asthmatic airways results in increased inflammation and angiogenesis, implicating it as a central part of asthma pathogenesis. However, to date, the path underlying these diminished COL4A3 levels has been elusive. This study investigated a possible mechanism underlying the reduction of COL4A3 expression. Bronchial biopsies of 76 patients with asthma and 83 controls were subjected to RNA-sequencing and DNA methylation bead arrays to identify expression and methylation changes. The binding of ZNF263 was analysed by chromatin-immunoprecipitation sequencing coupled with quantitative (q)PCR. Effects of silencing, using small interfering RNA, on the expression were studied using qPCR. expression was significantly reduced in bronchial biopsies compared to healthy controls, whereas DNA methylation levels at cg11797365 were increased. expression levels were significantly low in asthmatics without inhaled corticosteroid (ICS) use, whereas the expression was not statistically different between asthmatics using ICS and controls. Methylation levels at cg11797365 were increased upon consecutive rhinovirus infections. Our data indicate an epigenetic modification as a contributing factor for the loss of expression in asthmatic airway epithelium.

This cross-sectional study aimed to investigate the prevalence of self-reported and clinically screened swallowing dysfunction (dysphagia) in COPD patients with severe exacerbations and to identify any associated factors. Findings were then compared to a control group. Participants included 30 patients hospitalised due to a COPD exacerbation. The control group consisted of 30 adults hospitalised with acute cardiac symptoms. Data were derived from spirometry, the 150 mL timed water swallow test, a cookie swallow test and a dyspnoea questionnaire (modified Medical Research Council (mMRC)). Scores from the 10-item Eating Assessment Tool (EAT-10) were calculated to assess patient perception of swallowing dysfunction. Self-reported swallowing dysfunction and clinical signs thereof were more common in COPD patients than in the control group (67% 23% and 80% 37%, respectively; p≤0.001). Clinical signs of swallowing dysfunction in the group with acute exacerbation of COPD were associated with self-reportef COPD. Both groups also experienced xerostomia.A combination of airway clearance techniques are applied for people with bronchiectasis, together with recommendations for exercise and suggestions for management of common comorbidities https//bit.ly/2U3c99H. Childhood interstitial and diffuse lung diseases (chILD) encompass a broad spectrum of rare pulmonary disorders. In most developing Middle Eastern countries, chILD is still underdiagnosed. Our objective was to describe and investigate patients diagnosed with chILD in a tertiary university hospital in Egypt. We analysed data of consecutive subjects (aged <18 years) referred for further evaluation at the Children's Hospital, Ain Shams University (Cairo, Egypt). Diagnosis of chILD was made in accordance with the ChILD-EU criteria. The following information was obtained demographic data, clinical characteristics, chest computed tomography findings, laboratory studies, spirometry, bronchoalveolar lavage and histopathology findings. 22 subjects were enrolled over 24 months. Median age at diagnosis was 7 years (range 3.5-14 years). The most common manifestations were dyspnoea (100%), cough (
