Xiaochuan Xie, Xiaohan Shi, Peng Chen, Li Rao
PURPOSE: Recently, the roles of TIM-1 genetic polymorphisms in asthma have been extensively studied, with conflicting results. Therefore, we performed the present meta-analysis to better assess potential associations of TIM-1 genetic polymorphisms with asthma. METHODS: Eligible articles were searched in PubMed, Medline, EMBASE, Google Scholar, and CNKI up to December 2016. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to detect any potential associations between TIM-1 genetic polymorphisms and asthma...

BACKGROUND/INTRODUCTION: Indoleamine 2,3-dioxygenase (IDO) metabolizes tryptophan to kynurenine. An increase of its activity is associated with severity in patients with pneumonia. In chronic obstructive pulmonary disease (COPD) patients, an elevation of serotonin has been reported. Experimental models showed that cigarette smoke inhibits monoamine oxidase (MAO) leading to higher levels of serotonin. We investigated the prognostic ability of tryptophan, serotonin, kynurenine, IDO, and tryptophan hydroxylase (TPH) to predict short- and long-term outcomes in patients with a COPD exacerbation...

INTRODUCTION: During transplant surgeries, the lung experiences an ischaemia-reperfusion (I/R)-induced damage identified as a significant cause of morbidity and mortality. However, the mechanisms by which I/R induces leucocyte accumulation and subsequent tissue damage in lung surgeries remain unknown. Therefore, the present study aims to assess the role of monocyte chemotactic protein 1 (MCP-1) and macrophage inflammatory protein 2 (MIP-2) in leucocyte chemotaxis related to lung injury secondary to I/R...

BACKGROUND: Pleural biopsy is often obtained in patients with undiagnosed exudative pleural effusion during pleuroscopy. Standard forceps have been traditionally used for the biopsy. Cryoprobes are being increasingly used for transbronchial lung biopsy as they obtain larger specimens and have less crush artifact. However, the safety and feasibility of cryoprobe biopsy compared to standard forceps for pleural biopsy has not been fully assessed. OBJECTIVES: The objective of this study was to demonstrate the safety and feasibility of cryoprobe biopsy in the pleural space using semi-rigid pleuroscopy...

PURPOSE: Cough is common in chronic obstructive pulmonary disease (COPD) and is associated with frequent exacerbations and increased mortality. Cough increases during acute exacerbations (AE-COPD), representing a possible metric of clinical deterioration. Conventional cough monitors accurately report cough counts over short time periods. We describe a novel monitoring system which we used to record cough continuously for up to 45 days during AE-COPD convalescence. METHODS: This is a longitudinal, observational study of cough monitoring in AE-COPD patients discharged from a single teaching hospital...

PURPOSE: Idiopathic pulmonary fibrosis (IPF) is a progressive and lethal lung disease of unknown origin whose incidence has been increasing over the latest decade partly as a consequence of population ageing. New anti-fibrotic therapy including pirfenidone and nintedanib have now proven efficacy in slowing down the disease. Nevertheless, diagnosis and follow-up of IPF remain challenging. METHODS: This review examines the recent literature on potentially useful blood molecular and cellular biomarkers in IPF...

INTRODUCTION: Chronic obstructive pulmonary disease is a progressive lung disease characterized by abnormal cellular responses to cigarette smoke, resulting in tissue destruction and airflow limitation. Autophagy is a fundamental cellular process that eliminates long-lived proteins and damaged organelles through lysosomal degradation pathway, though its role in human diseases remains unclear. We hypothesized that an anti-aging protein, Klotho plays an important role in regulating autophagy in response to cigarette smoke (CS)...

PURPOSE: The acute respiratory distress syndrome (ARDS) represents a major challenge for clinicians as well as basic scientists. The mortality rate for ARDS has been maintained within the range of 40-52%. The authors have examined the involvement of the "cardiotonic steroids" in the pathogenesis and therapy of ARDS. We have studied the possible role of the bufadienolide, marinobufagenin (MBG), in the pathogenesis of ARDS in both a rat model of ARDS and in patients afflicted with that disorder...

REVIEW
Silvano Dragonieri, Giorgio Pennazza, Pierluigi Carratu, Onofrio Resta
Electronic noses (e-noses) are based on arrays of different sensor types that respond to specific features of an odorant molecule, mostly volatile organic compounds (VOCs). Differently from gas chromatography and mass spectrometry, e-noses can distinguish VOCs spectrum by pattern recognition. E-nose technology has successfully been used in commercial applications, including military, environmental, and food industry. Human-exhaled breath contains a mixture of over 3000 VOCs, which offers the postulate that e-nose technology can have medical applications...
