BACKGROUND: Most patients with restriction have a PFT pattern in which TLC, FVC and FEV1 are reduced to a similar degree. We call this pattern 'simple' restriction (SR). In contrast, we commonly observe a pattern in which FVC percent predicted (pp) is disproportionately reduced relative to TLCpp. We term this pattern 'complex restriction' (CR) and attempted to characterize its clinical, radiologic and physiologic features. METHODS: We reviewed PFTs of patients tested between November 2009 and June 2013 who had restriction (TLC<LLN)...

The finding of collections of macrophages/histiocytes in lung biopsy and bronchoalveolar lavage is relatively common in routine practice. This morphological feature in itself is pathological, but the exact clinical significance and underlying disease should be evaluated together with clinical data, functional respiratory and laboratory tests and imaging studies.Morphological characteristics of macrophages and their distribution along the different pulmonary structures should be examined carefully by pathologists...

BACKGROUND: Interstitial lung disease (ILD) can be a severe extra-articular disease manifestation in Rheumatoid Arthritis (RA). A potential role of fibrocytes in RA associated ILD (RA-ILD) has not previously been described. We present a modified faster method for measuring circulating fibrocytes, without intracellular staining. The results are compared to the traditional culture method, where the number of monocytes that differentiate into mature fibrocytes in vitro are counted. The results are following compared to disease activity in patients with severe asthma, ILD, RA (without diagnosed ILD) and RA with verified ILD (RA-ILD)...

The compliant thoracic artificial lung (cTAL) has been studied in acute in vivo and in vitro experiments. The cTAL's long-term function and potential use as a bridge to lung transplantation are assessed presently. The cTAL without anticoagulant coatings was attached to sheep (n = 5) via the pulmonary artery and left atrium for 14 days. Systemic heparin anticoagulation was used. Compliant thoracic artificial lung resistance, cTAL gas exchange, hematologic parameters, and organ function were recorded. Two sheep were euthanized for nondevice-related issues...

Lung surfactant proteins (SP) play critical roles in surfactant function and innate immunity. SP-A and SP-D, members of the collectin family of C-type lectins, exhibit distinct ligand specificities, effects on surfactant structure, and host defense functions despite extensive structural homology. SP-A binds to dipalmitoylphosphatidylcholine (DPPC), the major surfactant lipid component, but not phosphatidylinositol (PI), whereas SP-D shows the opposite preference. Additionally, SP-A and SP-D recognize widely divergent pathogen-associated molecular patterns...

One of the primary objectives in management of chronic obstructive pulmonary disease (COPD) is preventing decrease in lung function and reducing the annual number of acute exacerbations of COPD (AECOPD). An oral course of systemic corticosteroids is a commonly used treatment in AECOPD. We hypothesize that this treatment also increases exercise performance and decreases muscle fatigue. In a randomized double-blinded, parallel, placebo-controlled trial, we investigated 14 men (8 on prednisolone 37.5 mg vs. 6 on placebo) with severe and very severe COPD...

OBJECTIVE: To obtain evidence whether the online pulmonary rehabilitation(PR) programme 'my-PR' is non-inferior to a conventional face-to-face PR in improving physical performance and symptom scores in patients with COPD. DESIGN: A two-arm parallel single-blind, randomised controlled trial. SETTING: The online arm carried out pulmonary rehabilitation in their own homes and the face to face arm in a local rehabilitation facility. PARTICIPANTS: 90 patients with a diagnosis of chronic obstructive pulmonary disease (COPD), modified Medical Research Council score of 2 or greater referred for pulmonary rehabilitation (PR), randomised in a 2:1 ratio to online (n=64) or face-to-face PR (n=26)...

INTRODUCTION: Pulmonary congestion is a common finding of heart failure (HF), but it remains unclear how pulmonary and heart blood volumes (Vp and Vh) and extravascular lung water (EVLW) change in stable HF and impact lung function. METHODS: Fourteen patients with HF (age: 68±11 y; LVEF: 33±8%) and 12 controls (age: 65±9 y) were recruited. A pulmonary function test, thoracic CT scan, and contrast perfusion scan were performed. From the thoracic scan, a histogram of CT attenuation of lung tissue was generated and skew, kurtosis, and full-width half-max were calculated as surrogates of EVLW...

OBJECTIVES: Spirometry is known to be a gold standard for the diagnosis of chronic obstructive pulmonary disease (COPD). COPD Assessment Test (CAT) is an eight-item questionnaire currently in use to evaluate patients with COPD. In the present study, we aimed to evaluate if CAT is an adequate tool for screening COPD. METHODS: In total, 600 persons aging ⩾40 years old were randomly selected from three different family practice units located in the city center. CAT was asked to the participants and a spirometry was used to assess pulmonary obstruction...
