BACKGROUND: Gelsolin is an actin-scavenger controlling the tissue damage from actin in the blood. Gelsolin levels in circulation drops when tissue damage and corresponding actin release is pronounced due to catabolic conditions. The purpose of this study was to determine if low plasma gelsolin independently predicts a reduced chance of weaning from ventilator-demanding respiratory failure in critically ill patients within 28 days from admission. RESULTS: This cohort study included 746 critically ill patients with ventilator-demanding respiratory failure from the randomized clinical trial, "Procalcitonin And Survival Study"...

BACKGROUND: The incidence of lung abscess acquired in the community is unknown, but this is a common clinical problem encountered in developing countries. The incidence of lung abscess was high in the pre-antibiotic era but the advent of susceptible antibiotics it has reduced with an equal fall in mortality to 8.7%. With the emerging antibiotic resistance and change in the trends of bacteriological profile causing lung abscess, it is the need of time to reevaluate lung abscess. AIM: The study aimed to determine the clinical, radiological and bacteriological profile of lung abscess...

Oxidative stress is a common phenomenon and is linked to a wide range of diseases and pathological processes including aging. Tissue-specific variation in redox signaling and cellular responses to oxidative stress may be associated with vulnerability especially to age-related and chronic diseases. In order to provide a basis for tissue-specific difference, we examined the tissue-specific transcriptional features of 101 oxidative stress-associated genes in 10 different tissues and organs of healthy mice under physiological conditions...

Recipients of lung transplantation (LuTx) may experience impaired muscle function and bone metabolism even after rehabilitation. We investigated the potential use of musculoskeletal markers in identifying the impairment of muscle function and bone function in these patients. Biochemical parameters, bodily functions, and lung function of 37 LuTx recipients were evaluated at the time of their discharge from the hospital stay and about 6 months later. The biomarkers were also assessed in 30 healthy age and gender distribution-matched controls...

INTRODUCTION: CF pulmonary guidelines recommend alternate therapy (one month on, one month off) with inhaled tobramycin for chronic Pseudomonas aeruginosa colonization in cystic fibrosis (CF). Tobramycin-inhaled powder (TIP™) is increasingly replacing time-consuming nebulizer therapy. It is unclear whether laboratory parameters change during the month off period compared with the month on therapy. PURPOSE: Our aim was to assess whether spirometry, lung clearance index and circulating inflammatory markers differ between on/off treatment periods...

INTRODUCTION: Air pollution impacts health by increasing mortality and the incidence of acute events in unhealthy individuals. In contrast, the acute effects of pollution in healthy individuals are less obvious. The present study was designed to evaluate the associations between short-term exposure to air pollution on one hand and lung function, and inflammatory markers on the other in middle-aged, non-smoking adults with no respiratory disease, in two urban areas in northern France. METHODS: A sample of 1506 non-smoking adults (aged from 40 to 65) with no respiratory disease was selected from the participants in the 2011-2013 cross-sectional Enquête Littoral Souffle Air Biologie Environnement (ELISABET) survey in two urban areas in the northern France...

AIM: The lungs-and particularly the alveolar-capillary membrane-may be sensitive to continuous flow (CF) and pulmonary pressure alterations in heart failure (HF). We aimed to investigate long-term effects of CF pumps on respiratory function. METHODS AND RESULTS: We conducted a retrospective study of patients with end-stage HF at our institution. We analysed pulmonary function tests [e.g. forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1 )] and diffusing capacity of the lung for carbon monoxide (DLCO ) from before and after left ventricular assist device (LVAD) implantation and compared them with invasive haemodynamic studies...

High fat diet (HFD) decreases the lifespan of mice, and is a risk factor for several human diseases. Here, we investigated the effects of a HFD on lung epithelial and stem cells and its interaction with aging. Young and old mice were fed with either a standard diet (SD) or a HFD then their trachea and lung were examined for histological changes, inflammation, and mitochondrial function. Their stem cell function was examined using the in vitro organoid/colony forming efficiency (CFE) assay. Aging reduced the number of tracheal basal and alveolar type-2 (AT2) cells...

PURPOSE: To detect early, curable lung cancer, screening using low-dose CT (CT screening) was initiated in Japan and Western countries around the early 1990s. MATERIAL AND METHODS: In 2013, the National Lung Screening Trial (NLST) reported that annual CT screening for high-risk participants leads to a 16% reduction in lung cancer death. In Hitachi City, CT screening for citizens 50 years of age or older was started in 1998, and 30% of the citizens had received a CT examination at least once by 2006...

PURPOSE: Asthma is a heterogeneous disease that responds to medications to varying degrees. Cluster analyses have identified several phenotypes and variables related to fixed airway obstruction; however, few longitudinal studies of lung function have been performed on adult asthmatics. We investigated clinical, demographic, and inflammatory factors related to persistent airflow limitation based on lung function trajectories over 1 year. METHODS: Serial post-bronchodilator forced expiratory volume (FEV) 1% values were obtained from 1,679 asthmatics who were followed up every 3 months for 1 year...

Three cigarette smoking behaviors influence lung cancer rates: how many people start, the amount they smoke, and the age they quit. California has reduced smoking faster than the rest of the US and trends in these 3 smoking behaviors should inform lung cancer trends. We examined trends in smoking behavior (initiation, intensity, and quitting) in California and the rest of US by regression models using the 1974-2014 National Health Interview Surveys (n=962,174). Lung cancer mortality data for 1970-2013 was obtained from the national Surveillance, Epidemiology, and End Results (SEER) Program...
