Few studies have systematically evaluated high-resolution CT (HRCT) imaging of the thorax 5 years after severe ARDS to determine the association between radiologic fi ndings and functional disability. The primary aim of this study was to determine chest radiologic abnormalities at 5 years in survivors of severe ARDS from the University of Toronto ARDS cohort. The secondary aim was to determine the relationship between the observed radiologic abnormalities on HRCT scan and pulmonary symptoms, pulmonary function test abnormalities, and healthrelated quality of life at 5-year follow-up. ⋯ Exercise and functional limitations experienced by survivors of severe ARDS are unlikely to be related to structural lung disease and may be more consistent with extrapulmonary muscle weakness.

The prognostic significance of the tumor microenvironment, which is created by both cancer cells and cancer-associated fibroblasts (CAFs), has been increasingly recognized. The purpose of this study was to analyze the prognostic markers of stage I squamous cell carcinoma (SqCC), with special reference to the immunophenotypes of both cancer cells and CAFs. ⋯ The current study indicates that immunophenotypes of CAFs could have a prognostic value independent of those of the cancer cells in SqCC.

Cardiac sarcoidosis (CS) is known to be associated with congestive heart failure, conduction disorders, and tachyarrhythmias. Ventricular arrhythmias are the most feared cardiac manifestation because they often are unpredictable, may be the fi rst manifestation of the disease, and may be fatal. The propensity for the development of supraventricular arrhythmias (SVAs) in patients with CS has not been described. The aim of this study was to assess the prevalence as well as the predictors of SVA. ⋯ The study systematically evaluated the frequency of SVA in a large number of patients with CS. SVA in patients with CS is frequent and associated with symptoms. LAE was clearly associated with the development of SVA in this patient population. The extent to which LAE predicts the occurrence of SVA in larger, more diverse CS populations should be evaluated prospectively.

It is well known that oral corticosteroid and anti-tumor necrosis factor-α agents increase the risk of TB. However, little is known about whether inhaled corticosteroid (ICS) increases the risk of TB. We performed this study to assess the risk of pulmonary TB among ICS users, based on the presence of the radiologic sequelae of pulmonary TB. ⋯ ICS use increases the risk of pulmonary TB in patients with COPD and the risk is greater in patients who have radiologic sequelae of prior pulmonary TB.

The lack of mandatory clinical registries for idiopathic pulmonary fibrosis (IPF) has meant a reliance on routine clinical data to provide trends in disease incidence. Death certificate and primary care data suggest that the incidence of IPF has increased in the United Kingdom at a rate of approximately 5% per year, but due to possible concerns about the diagnostic validity of these clinical datasets, it is helpful also to analyze data from secondary care. We used national secondary care data to determine trends in hospital admissions for IPF clinical syndrome (IPF-CS) in England between 1998 and 2010. ⋯ Hospital admissions for IPF-CS in England follow a similar trend to other data sources in the United Kingdom . This has resulted in escalating costs of inpatient care, which is a significant financial burden on health-care resources.
