COPD is highly prevalent in the US and globally, requiring new treatment strategies due to the high disease burden and increase in the aging population. Here, we profile the newly FDA-approved LONHALA MAGNAIR (glycopyrrolate [GLY]/eFlow® Closed System [CS]; 25 mcg twice daily), a nebulized long-acting muscarinic antagonist (LAMA) for the long-term maintenance treatment of COPD, including chronic bronchitis and/or emphysema. Areas covered: An overview of COPD and the treatment landscape, focusing on GLY/eFlow CS, is reported by reviewing the published literature pertinent to the drug/device combination...

BACKGROUND: Cough and sputum production (symptoms of bronchitis) are common in chronic obstructive pulmonary disease (COPD). Extrapulmonary comorbidities, such as gastroesophageal reflux disease (GERD) and post-nasal drip, also cause bronchitis symptoms. The impact of extrapulmonary comorbidities on the severity of bronchitis symptoms in COPD is unknown. The aim of this study was to quantify bronchitis symptoms and assess the impact of GERD and nasal symptoms on the severity of bronchitis symptoms in COPD...

This paper aims to verify the association between chronic diseases and handgrip strength (HS) in the older adults of Florianópolis, SC. This is a cross-sectional analysis of a longitudinal population-based study. HS was measured by dynamometer. Independent variables included 10 chronic diseases and falls. Simple and multiple linear regression analyses were performed. In the final model, in women, arthritis/rheumatism/arthrosis (β: -1.27; 95%CI: -2.55; -0.20) was associated with lower HS and bronchitis/ asthma (β: 1...

RATIONALE: Roflumilast reduces exacerbations in patients with severe chronic obstructive pulmonary disease associated with chronic bronchitis and a history of exacerbations. Further characterization of patients most likely to benefit is warranted. OBJECTIVES: Define characteristics that most robustly identify patients who derive greatest exacerbation risk reduction with roflumilast. METHODS: Predefined, pooled analyses of REACT (NCT01329029) and RE2 SPOND (NCT01443845) multicenter, randomized, double-blind, placebo-controlled studies...

Chlamydia pneumoniae is an obligate intracellular pathogen responsible for respiratory diseases, including pneumonia and bronchitis, and is highly involved in chronic diseases, including atherosclerosis, asthma, and Alzheimer's disease. We previously showed that the host apoptotic factor caspase-9 played a crucial role for chlamydial multiplication and host apoptosis inhibition by chlamydial infection. To identify chlamydial genes interacting with human caspase-9, yeast two-hybrid screening was performed and 5 chlamydial genes, including Cpj0838 and pmpG were isolated from the C...

BACKGROUND: Dyspnea is a common and ambiguous complaint that results in 3.4 million emergency department visits annually. While learners may encounter lists of differential diagnoses to consider while in training, often these lists are not empirically based. We sought to establish an evidence-based differential diagnosis for dyspnea and to determine whether normal vital signs can rule out a life-threatening diagnosis. METHODS: We analyzed data from the National Hospital Ambulatory Medical Care Survey from 2005-2014 for emergency department visits with a chief complaint of dyspnea and tallied the principal discharge diagnosis...

Lung sounds, which include all sounds that are produced during the mechanism of respiration, may be classified into normal breath sounds and adventitious sounds. Normal breath sounds occur when no respiratory problems exist, whereas adventitious lung sounds (wheeze, rhonchi, crackle, etc.) are usually associated with certain pulmonary pathologies. Heart and lung sounds that are heard using a stethoscope are the result of mechanical interactions that indicate operation of cardiac and respiratory systems, respectively...

Hypersecretion of viscous mucus is one of the hallmark symptoms of acute and chronic bronchitis and typically develops secondary to an inflammation of the airway epithelium. Bronchipret® TP film-coated tablets (BRO), an herbal medicinal product containing a fixed combination of thyme herb and primula root extracts, has been successfully used clinically for the treatment of acute bronchitis for more than two decades. However, the underlying pharmacological mechanisms of action have not been fully understood so far...

The binary approach to the diagnosis of Chronic Bronchitis (CB) is a major barrier to the study of the disease. We investigated whether severity of productive cough can be graded using symptoms and presence of fixed airflow obstruction (FAO), and whether the severity correlates with health status, exposures injurious to the lung, biomarkers of inflammation, and measures of airway wall thickening. Findings from a cross-sectional sample of 1,422 participants from the Lovelace Smokers Cohort (LSC) were validated in 4,488 participants from the COPDGene cohort (COPDGene)...

While adenoid cystic carcinoma is a common malignancy to arise within the salivary glands (21.9%) (Kokemueller et al. in Int J Oral Maxillofac Surg 33:25-31, 2004), it is seldom encountered as a tracheal mass and represents < 1% of all lung cancers. Tracheal tumors are an uncommon cause of dyspnoea due to their relatively rare occurrence (Baydur and Gottlieb in JAMA 234:829-831, 1975). They pose considerable diagnostic challenge clinically as their symptoms mimics more commoner ailments like asthma and chronic bronchitis...

Inflammatory bowel disease (IBD) is associated with a number of immune-mediated extra-intestinal manifestations. Over half of all IBD patients have some form of respiratory pathology, most commonly neutrophil-mediated diseases such as bronchiectasis and chronic bronchitis. Using murine models of colitis, we aimed to identify the immune mechanisms driving pulmonary manifestations of IBD. We found increased neutrophil numbers in lung tissue associated with the pulmonary vasculature in both trinitrobenzenesulfonic acid- and dextran sulfate sodium-induced models of colitis...
