INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is considered a disease of older patients, being rare in patients ≤ 50 years. Still, IPF can occur in younger patients, but this particular patient group is not well characterised so far. The aim of this study was to compare the diagnostic certainty, clinical features, comorbidities and survival in young versus older IPF patients. METHODS: We reviewed our medical records from February 2011 until February 2015, to identify IPF patients, who were then classified as young (≤ 50 years) or older IPF (> 50 years)...

REVIEW
Aleksandra Nikolic
Bronchiectasis is characterized by deregulated inflammatory response and recurrent bacterial infection resulting in progressive lung damage and an irreversible dilatation of bronchi and bronchioles. Generally accepted model of the development of bronchiectasis is the "vicious cycle hypothesis" that proposes compromising of the mucociliary clearance by an initial event, which leads to the infection of the respiratory tract followed by further impairment of mucociliary function, bacterial proliferation, and more inflammation...

INTRODUCTION: Obstructive sleep apnoea (OSA) is characterised by a low-grade systemic and airway inflammation; however, the regulatory mechanisms of inflammation are poorly explored. Survivin (Birc5) is an anti-apoptotic protein which inhibits Type 1 inflammation; however, this molecule has not been investigated in OSA. METHODS: Forty-five patients with OSA and 31 non-OSA control subjects were involved. Venous blood was collected for plasma survivin measurements before and after diagnostic overnight polysomnography...

INTRODUCTION: Geriatric assessment (GA) for older patients with lung cancer could provide insight into vulnerability, cognitive impairment, and risk of toxicity. Discontinuation and complications of intensive treatment could potentially be prevented in vulnerable and frail patients. This study aimed to evaluate current clinical practice of GA for older patients with lung cancer in the Netherlands and identify potential hurdles for implementation. METHODS: Pulmonologists and radiation oncologists participating in the NVALT25-ELDAPT trial completed an online questionnaire regarding current practice of GA, added value of GA for treatment decision-making and logistic barriers for patients with non-small cell lung cancer...

INTRODUCTION: microRNAs (miRNAs) are small non-coding 1RNAs that post-transcriptionally regulate gene expression. Recent evidence shows that adenosine deaminases that act on RNA (ADAR) can edit miRNAs. miRNAs are involved in the development of different diseases, such as idiopathic pulmonary fibrosis (IPF). In IPF, about 40% of the miRNAs are differentially expressed with respect to controls. Among these miRNAs, miRNA-21 has been found over-expressed in IPF and its targets are anti-fibrosing molecules such as PELI1 and SPRY2...

PURPOSE: The maintaining of asthma control is difficult due to high variability in response to therapy among patients. Since matrix metalloproteinase 9 (MMP9) is implicated in inflammation and remodeling of asthmatic airways, it could be associated with adequate response to asthma therapy. The aim of this study was to investigate whether variants in 3' end of the MMP9 gene are associated with clinical phenotype and responsiveness to treatment in children with asthma. METHODS: The study included 127 asthmatic children from Slovenia...

BACKGROUND: Plasma pro-BNP (brain natriuretic peptide) levels are often elevated in response to right ventricular (RV) volume and pressure overload, parameters potentially affected by exercise. Plasma pro-BNP levels change in association with long-term changes in pulmonary hemodynamics, thereby serving as a potential biomarker in pulmonary arterial hypertension (PAH). The 6-min Walk Test (6MWT) and pro-BNP level are often checked in a single office visit. There is no universal standard for measuring Pro-BNP levels relative to the timing of the 6MWT...

PURPOSE: Body composition is known to influence the development and progression of chronic respiratory diseases (CRDs). We sought to characterize the unique anthropometric phenotypes that present with asthma, chronic obstructive pulmonary disease (COPD), and chronic bronchitis across four distinct settings in Peru. METHODS: We collected sociodemographic, clinical history, and spirometry data from 2959 participants from Lima, Tumbes, and rural and urban Puno. We compared the prevalence of CRDs among different study sites and described disease phenotypes...

#14
Mikkel Brabrand, Daniel Pilsgaard Henriksen
IMPORTANCE: The CURB-65 score is widely implemented as a prediction tool for identifying patients with community-acquired pneumonia (cap) at increased risk of 30-day mortality. However, since most ingredients of CURB-65 are used as general prediction tools, it is likely that other prediction tools, e.g. the British National Early Warning Score (NEWS), could be as good as CURB-65 at predicting the fate of CAP patients. OBJECTIVE: To determine whether NEWS is better than CURB-65 at predicting 30-day mortality of CAP patients...

Although included in the serological domain of the 'interstitial pneumonia with auto-immune features' (IPAF) research statement, the search for myositis-specific antibodies (MSA) is not incorporated in routine clinical practice. The objective of the study was to evaluate MSA prevalence in an idiopathic interstitial pneumonia (IIP) cohort (n = 68) with suggestive morphological interstitial lung disease patterns. Twelve of 68 patients (17.6%) carried MSA, whereof only two were anti-nuclear antibody-positive...

Exercise training has been shown to reduce symptoms and exacerbations in COPD patients; however, the exercise effect on patients' immune response is poorly known. We thus verified if an exercise program (EP) impacted on proliferative T cell response of COPD patients. Fourteen non-O2 dependent COPD patients on standard treatment were studied. EP consisted in 24 sessions of aerobic and muscular training. Peripheral blood mononuclear cells were stimulated with the mitogen phytohemagglutinin and antigens from Haemophilus influenzae and cytomegalovirus, and the lymphocyte proliferative response (LPR) was assessed through the expression of Ki67 before and after the EP...

INTRODUCTION: Diaphragm excursion and contraction velocity measured using ultrasonography have been used to assess diaphragm function. We aimed to evaluate the performance of diaphragm ultrasonography during weaning from mechanical ventilation (MV). METHODS: Diaphragm ultrasonography was performed on 73 mechanically ventilated patients who were being considered for extubation on three separate occasions: (1) on assist control mode (A/C) during consistent patient triggered ventilation, (2) following 30 min during a spontaneous breathing trial (SBT), (3) 4-24 h following extubation...

INTRODUCTION: A number of studies indicate that endothelin-1 (ET-1) may act as an inflammatory cell "gatekeeper," by regulating the influx of neutrophils following pulmonary injury. To further examine the role of ET-1 in modulating lung inflammation, hamsters were treated with an endothelin receptor antagonist (ERA), HJP272, either 1 h prior to intratracheal instillation of amiodarone (AM) or 24 h afterwards. METHODS: In both cases, the extent of lung injury and repair was determined by (1) histopathological changes; (2) neutrophil content in bronchoalveolar lavage fluid (BALF); (3) lung collagen content; (4) tumor necrosis factor receptor 1 expression by BALF macrophages; (5) BALF levels of (a) transforming growth factor beta-1, (b) stromal cell-derived factor 1 (commonly referred to as CXCL12), and (c) platelet-derived growth factor BB; (6) alveolar septal cell apoptosis...

Adolescent idiopathic scoliosis may require surgical treatment for extreme curvature of the spine or loss of pulmonary function. We present a report of a 31-year-old woman with a history of scoliosis and anterolateral spinal fusion who developed chest pain and hemoptysis. Imaging revealed that a fixation rod had migrated cephalad, penetrating the diaphragm into the left lower lobe of the lung. The hardware was removed and lung repaired with good results. This is the first reported case of cranial spinal rod migration over a decade after initial implantation...
