BACKGROUND: The independent association of recent infection with venous thromboembolism is uncertain. The purpose of the study was to test both overall infection (site unspecified) and specific infection sites as potential risk factors for deep vein thrombosis and pulmonary embolism adjusting for other known venous thromboembolism factors. METHODS: Using Rochester Epidemiology Project (REP) resources, we identified all Olmsted County, MN residents with objectively-diagnosed incident deep vein thrombosis or pulmonary embolism over the 13-year period, 1988-2000 (cases; n=1303), and 1-2 residents without venous thromboembolism matched to each case on age, sex and incident venous thromboembolism date (controls; n=1494)...

REVIEW
Phillip W Clapp, Ilona Jaspers
PURPOSE OF REVIEW: Vaping is gaining popularity in the USA, particularly among teens and young adults. While e-cigs are commonly represented as safer alternatives to tobacco cigarettes, little is known regarding the health effects of their short- or long-term use, especially in individuals with pre-existing respiratory diseases such as asthma. Flavored e-cig liquids (e-liquids) and e-cig aerosols contain airway irritants and toxicants that have been implicated in the pathogenesis and worsening of lung diseases...

REVIEW
Ji-Wook Yoon, Jong-Heun Lee
Semiconductor gas sensors using metal oxides, carbon nanotubes, graphene-based materials, and metal chalcogenides have been reviewed from the viewpoint of the sensitive, selective, and reliable detection of exhaled biomarker gases, and perspectives/strategies to realize breath analysis on a chip for disease diagnosis are discussed based on the concurrent design of high-performance sensing materials and miniaturized pretreatment components. Carbon-based sensing materials that show relatively high responses to NO and NH3 at low or mildly raised temperatures can be applied to the diagnosis of asthma and renal disease...

A challenge in the Choosing Wisely campaign is to identify low-value clinical actions supported by high-quality evidence. We applied a method based on crowdsourcing the Daily POEM (patient-oriented evidence that matters) to identify low-value clinical actions from research studies consistent with the principles of Choosing Wisely. In 2016, we analyzed an average of 1,382 questionnaires on 265 unique POEMs delivered to physician members of the Canadian Medical Association. From these questionnaires, we identified the POEMs ranking highest on one questionnaire item directly linked to reducing overdiagnosis or overtreatment...

Reports of chronic eosinophilic pneumonia (CEP) after radiation therapy are limited to breast cancer. We herein describe a case of CEP after radiation therapy for lung cancer. The patient was a 65-year-old man who had asymptomatic peripheral blood eosinophilia but no history of asthma or allergy. One month after completion of radiation therapy, chest CT scan revealed infiltrates inside the irradiated area, leading to the diagnosis of radiation pneumonitis. His condition improved after receiving corticosteroids...

Prostaglandin (PG) D2 has been in the focus of research for quite a long time, but its biological effects and its roles in human disease are still not fully characterized. When in 2001 a second major PGD2 receptor termed chemoattractant receptor homologue expressed on Th2 cells (CRTH2; alternative name DP2) was discovered, diverse investigations started to shed more light on the complex and often controversial actions of the prostaglandin. With various immunomodulating effects, such as induction of migration, activation, and cytokine release of leukocytes observed both in vivo and in vitro, CRTH2 has emerged as a promising target for the treatment of allergic diseases...

BACKGROUND: Common diseases with potential to increase the risk of death from lung cancer have so far not been studied in large populations. METHODS: We did a population-based retrospective cohort study using nationwide health insurance claims data from 2005 to 2012 in Korea including 205 403 lung cancer patients. Multivariate-adjusted hazard ratios (aHRs) of lung cancer mortality by presence, time intervals with lung cancer diagnosis and combinations of pre-existing chronic obstructive pulmonary disease (COPD), pneumonia, asthma and tuberculosis were calculated using the Cox-proportional hazards model...

Exposure to particulate matter (PM) is recognized as a major health hazard, but molecular responses are still insufficiently described. We analyzed the epigenetic impact of ambient PM2.5 from biomass combustion on the methylome of primary human bronchial epithelial BEAS-2B cells using the Illumina HumanMethylation450 BeadChip. The transcriptome was determined by the Affymetrix HG-U133 Plus 2.0 Array. PM2.5 induced genome wide alterations of the DNA methylation pattern, including differentially methylated CpGs in the promoter region associated with CpG islands...

Fine Particulate Matter (PM(2.5)-particles with an aerodynamic diameter ≤2.5 μm) can penetrate deeply into the lung, deposit in the alveoli, and consequently impair lung function. Both short term and long term exposures to PM(2.5) are associated with the incidence of respiratory diseases (e.g. asthma, chronic obstructive pulmonary disease, lung cancer). This paper summarizes the effects of ambient air PM(2.5) exposure on human respiratory system revealed by epidemiological studies.

miR-20b is a member of the miR-106a-363 gene cluster, which has been shown to play an important role in a variety of diseases, including cancer, inflammation, and autoimmune diseases. Our previous study indicated that miR-20b has an inhibitory effect on airway inflammation in asthmatic mice, but the exact mechanism is unclear. In this study, we report that the ratio of CD11b+Ly6G+Ly6Clow cells, but not the amount of CD11b+Ly6C+Ly6G- cells, was increased in the lung tissue of asthmatic mice after intranasal instillation with miR-20b mimics, while Th2-type cytokines (interleukin (IL)-4 and IL-13) were significantly decreased in the bronchoalveolar lavage fluid...

The pulmonary extracellular matrix (ECM) determines the tissue architecture of the lung, and provides mechanical stability and elastic recoil, which are essential for physiological lung function. Biochemical and biomechanical signals initiated by the ECM direct cellular function and differentiation, and thus play a decisive role in lung development, tissue remodelling processes and maintenance of adult homeostasis. Recent proteomic studies have demonstrated that at least 150 different ECM proteins, glycosaminoglycans and modifying enzymes are expressed in the lung, and these assemble into intricate composite biomaterials...

BACKGROUND: Occupational exposure to cobalt is well established in hard metal manufacture. Cobalt is known to cause contact allergy, asthma, hard metal lung disease, and lung cancer. The relationship between skin exposure and uptake determined in blood has not been extensively investigated. OBJECTIVE: To examine whether skin and inhalable air exposure to cobalt contributes to uptake, determined as cobalt in blood, in a hard metal manufacturing factory. METHODS: The amount of cobalt on the skin found with an acid wash technique, the air concentrations of inhalable cobalt and cobalt blood concentrations were determined and correlated in exposed workers...

Developing novel chemo-prevention techniques and advancing treatment are key elements to beating lung cancer, the most common cause of cancer mortality worldwide. Our previous cohort study showed that cysteinyl leukotriene receptor antagonists, mainly montelukast, decreased the lung cancer risk in asthma patients. In the current study, we conducted in vivo and in vitro experiments to demonstrate the inhibiting effect of montelukast on lung cancer and to investigate the underlying mechanisms. Using Lewis lung carcinoma-bearing mice, we showed that feeding montelukast significantly delayed the tumor growth in mice (p < 0...

IGF1R (Insulin-like Growth Factor 1 Receptor) is a tyrosine kinase with pleiotropic cellular functions. IGF activity maintains human lung homeostasis and is implicated in pulmonary diseases such as cancer, ARDS, COPD, asthma and fibrosis. Here we report that lung transcriptome analysis in mice with a postnatally-induced Igf1r gene deletion showed differentially expressed genes with potentially protective roles related to epigenetics, redox and oxidative stress. After bleomycin-induced lung injury, IGF1R-deficient mice demonstrated improved survival within a week...

NOTCH is a fundamental signaling system that regulates normal embryonic development and tissue homeostasis in adult life. NOTCH receptor is a single-pass transmembrane protein normally triggered via direct cell-to-cell contact, in which NOTCH ligands bind the extracellular domain of the receptor, inducing γ-secretase cleavage and release of intracellular domain. The intracellular domain binds to the transcriptional effector RBPJκ to activate transcription of target genes that regulate cell differentiation, patterning, and morphogenesis during embryonic development and adult life...
