Review Meta Analysis Comparative Study
A systematic review and meta-analysis of randomized trials and prospective studies comparing covered and bare self-expandable metal stents for the treatment of malignant obstruction in the digestive tract.
Self-expandable metal stents (SEMS) are widely used for the palliative treatment of malignant gastrointestinal obstruction. Our aim was to evaluate the evidence comparing covered and bare SEMS in the digestive tract using meta-analytical techniques. ⋯ Both covered and bare SEMS are comparable in efficacy for the palliative treatment of malignant obstruction in the digestive tract. Each type of the stents has its own merit and demerit relatively.

The US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS, formerly AERS) is a database that contains information on adverse event and medication error reports submitted to the FDA. Besides those from manufacturers, reports can be submitted from health care professionals and the public. The original system was started in 1969, but since the last major revision in 1997, reporting has markedly increased. ⋯ A survey of our previous reports suggested that the ROR provided the highest number of signals, and the EBGM the lowest. Additionally, an analysis of warfarin-, aspirin- and clopidogrel-associated adverse events suggested that all EBGM-based signals were included in the PRR-based signals, and also in the IC- or ROR-based ones, and that the PRR- and IC-based signals were in the ROR-based ones. In this article, the latest information on this area is summarized for future pharmacoepidemiological studies and/or pharmacovigilance analyses.

Randomized Controlled Trial
Procalcitonin-guided antibiotic use in acute exacerbations of idiopathic pulmonary fibrosis.
To assess the clinical value of procalcitonin to guide antibiotic therapy in acute exacerbations of idiopathic pulmonary fibrosis. ⋯ Procalcitonin-guided antibiotic therapy of patients with acute exacerbation of idiopathic pulmonary fibrosis may result in reduced exposure to antibiotics without adversely affecting patient outcomes.

Plasma fibrinogen is considered a biomarker of respiratory disease, owing to the relationship between plasma fibrinogen and pulmonary function established in Western populations. However, such a relationship has not yet been confirmed in an Asian population. We assessed this relationship in the general Japanese population. ⋯ Plasma fibrinogen was significantly associated with pulmonary function in Japanese men, and as such, plasma fibrinogen might be a potent biomarker for pulmonary dysfunction in men.

To investigate the relationship between hypoxia and in vitro "stemness" of cancer stem cells (CSCs). ⋯ Hypoxia may induce the "dedifferentiation" of differentiated glioma cells which then acquire the stemness.
