To identify potential risk factors for lung disease progression in children with cystic fibrosis (CF), we studied the longitudinal data of all children with CF (aged ≥5 years) registered in the Dutch CF Registry (2009-2014). Lung disease progression was expressed as a decline in lung function (FEV1 %pred) and the pulmonary exacerbation rate (PEx). Potential risk factors at baseline included: sex, age, best FEV1%pred, best forced vital capacity (FVC)%pred, genotype, BMI z-score, pancreatic insufficiency, medication use (proton pump inhibitors [PPI], prophylactic antibiotics, and inhaled corticosteroids), CF-related diabetes, allergic bronchopulmonary aspergillosis, and colonisation with Pseudomonas aeruginosa The data of 545 children were analysed...

Objective: Common comorbid medical conditions including allergic rhinitis (AR), obesity, and sleep disordered breathing (SDB) have been linked with asthma exacerbations; however, these conditions also impact sleep and academic functioning. The current study sought to examine unique and combined associations of these common comorbidities on sleep and academic performance among urban minority children with persistent asthma. We expected additional comorbid diagnoses would be associated with poorer sleep and academic functioning...

Asthma is a common pulmonary disorder characterizerized by airway inflammation, airway- hyper reactivity, and reversible airflow obstruction. The classic triad of symptoms is wheezing, chronic episodic dyspnea and chronic cough. The prevalence of asthma increased steadily over the latter part of the last century, first in the developed and then in the developing world. The number of people with asthma in the world may be as high as 334 million. Asthma in Bangladesh appears to be a substantial public health problem: an estimated 11...

OBJECTIVES: Neuroendocrine cell hyperplasia of infancy (NEHI) is a children's interstitial and diffuse lung disease of unknown etiology that presents in infancy with characteristic findings of tachypnea, retractions, crackles, and hypoxemia. At the present, the mainstay of treatment is oxygen supplementation to normalize oxygen saturations and decrease work of breathing. There are characteristic pulmonary function, radiographic, and histologic findings, but polysomnography (PSG) data has not been reported...

BACKGROUND: Bronchiectasis is being increasingly diagnosed and recognised as an important contributor to chronic lung disease in both adults and children in high- and low-income countries. It is characterised by irreversible dilatation of airways and is generally associated with airway inflammation and chronic bacterial infection. Medical management largely aims to reduce morbidity by controlling the symptoms, reduce exacerbation frequency, improve quality of life and prevent the progression of bronchiectasis...

Prenatal exposure to tobacco smoke is a significant risk-factor for airway disease development. Furthermore, the high prevalence of pregnant smoking women requires the establishment of strategies for offspring lung protection. Therefore, we here aimed to understand the molecular mechanism of how prenatal smoke exposure affects fetal lung development. We used a mouse model recapitulating clinical findings of prenatally exposed children, where pregnant mice were exposed to smoke until c-section or spontaneous delivery, and offspring weight development and lung function was monitored...

Phthalate exposure is related to the development of allergic diseases; however, studies regarding its effect on lung function are limited. Our study aims to identify an association between phthalate exposure at different ages and lung function in children at age 9 by conducting a cohort study. The Taiwan Birth Panel Study (TBPS) was established from April 2004 to January 2005. Urine samples were collected from children in the TBPS cohort at ages 2, 5, and 9years. Urinary phthalate metabolite concentrations were measured via ultrahigh-performance liquid chromatography coupled with tandem mass spectrometry...

Maternal smoking during pregnancy is associated with impaired lung function among young children, but less is known about long-term effects and the impact of adolescents' own smoking. We investigated the influence of maternal smoking during pregnancy, secondhand smoke exposure, and adolescent smoking on lung function at age 16 years.The BAMSE birth cohort collected information on participant's tobacco smoke exposure through repeated questionnaires, and measured saliva cotinine concentrations at age 16. Participants performed spirometry and impulse oscillometry (IOS) at age 16 (n=2295)...

Although aerosol black carbon (BC) exerts strong influences on human health, research on potential health risks of aerosol BC around the Qinghai-Tibet Plateau is very limited. This is the very first study to investigate the distribution of aerosol BC in a typical city of the Qinghai-Tibet Plateau and the resulting health risks. The results showed that the maximal real-time (5-min monitoring interval) concentration of aerosol BC was 22.34 μg/m3 , much higher than day- and week-averaged concentrations which were in the range of 1...

Recently, deficiency in the cytosolic DNA sensor RNA Polymerase III was described in children with severe primary varicella-zoster virus (VZV) infection in the CNS and lungs. In the present study we examined adult patients with VZV CNS infection caused by viral reactivation. By whole exome sequencing we identified mutations in POL III genes in two of eight patients. These mutations were located in the coding regions of the subunits POLR3A and POLR3E. In functional assays, we found impaired expression of antiviral and inflammatory cytokines in response to the POL III agonist Poly(dA:dT) as well as increased viral replication in patient cells compared to controls...

OBJECTIVE: Electrical impedance tomography (EIT) has been shown as a viable non-invasive, bedside imaging modality to monitor lung function.This paper introduces a method for identifying regions of air trapping from EIT data collected during tidal breathing and breath-holding maneuvers. APPROACH: Ventilation-perfusion index maps are computed from dynamic EIT images. These maps are then used to identify regions of air trapping in the area of the lung as regions that are poorly ventilated but well perfused throughout the breathing and cardiac cycles...

In cystic fibrosis, pulmonary function tests (PFTs) and computed tomography are used to assess lung function and structure, respectively. Although both techniques of assessment are congruent there are lingering doubts about which PFTs variables show the best congruence with computed tomography scoring. In this study we addressed the issue by reinvestigating the association between PFTs variables and the score of changes seen in computed tomography scans in patients with cystic fibrosis with and without pulmonary exacerbation...

Asthma - a prolonged respiratory disease related with hyper-responsiveness and increased inflammation of airways; affects millions peoples worldwide. Vitamin D possess anti-inflammatory and immunomodulatory activities. Its deficiency (the level less than 20 ng/mL in the serum) is found to be related to occurrence of pulmonary diseases including bacterial and viral infections and asthma. Some studies indicate that low levels of vitamin D in the serum are related to reduced lung function and increased airway inflammation as well as overall poor results in asthmatic patients...

BACKGROUND: Respiratory muscle weakness associated with scoliosis in type-2 spinal muscular atrophy (SMA) leads to respiratory impairment. Spinal brace, generally utilized to slow scoliosis progression and support sitting, could worsen lung function and hamper cough maneuvers. CASE SERIES: Six home-treated type-2 SMA children (aged 6 -15 years, subtype 2.1-2.5) were assessed to evaluate time-dependent influence of "static-balanced brace" on pulmonary function...
