Background and objectiveThe COPD Assessment Test (CAT) has been reported to have potential utility for measuring health status of idiopathic pulmonary fibrosis (IPF). Although the CAT has been developed for the assessment of COPD patients, it has not been fully evaluated exclusively in IPF. This study was designed to evaluate the validity of the CAT in IPF.
MethodsThe clinical data for 106 consecutive subjects with newly diagnosed IPF who completed pulmonary function tests, partial pressure of oxygen in arterial blood (PaO2 ) at rest, 6-min walk test (6MWT), CAT, St George's Respiratory Questionnaire (SGRQ), modified Medical Research Council (mMRC) dyspnoea grade and Hospital Anxiety and Depression Scale (HADS), were analysed. We assessed the validity of the CAT in comparison with the SGRQ.
ResultsThe present subjects showed mild to moderate restrictive impairment on spirometry. Mean CAT score and total SGRQ were 12.88.0 and 30.817.7, respectively. The concurrent validity of the CAT score in comparison with the SGRQ total score was significant (r=0.72, P<0.001). Internal consistency (Cronbach's =0.869) and repeatability over 3months (intraclass correlation coefficient=0.742) of the CAT were also significant. Single regression analysis showed that the CAT had significant construct validity. In multiple regression analysis, mMRC, PaO2 at rest, minimum SpO(2) during 6MWT and anxiety of HADS were independent predictors for the CAT.
ConclusionsThe CAT is a valid health status measurement in IPF patients. Multiple regression analysis showed that the CAT was significantly correlated with dyspnoea severity, oxygenation impairment and anxiety.
The validity of the COPD Assessment Test (CAT) was evaluated exclusively in idiopathic pulmonary fibrosis (IPF) patients in comparison with the St George's Respiratory Questionnaire (SGRQ). The CAT had a significant correlation with SGRQ and was independently predicted by dyspnoea severity, oxygenation impairment and anxiety.

Diazinon is an organophosphorus (OP) insecticide and is widely used not only in agriculture but also homes and garden in Japan. Diazinon has been reported to increase TNF-alpha production in rat serum and brain, suggesting that it can modify the proinflammatory response. In this study, we investigated the effects of diazinon on macrophage functions, such as cytokine production, reactive oxygen species (ROS) generation, cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) expressions, cell-surface molecule expressions, and phagocytosis in RAW264.7 cells. In RAW264.7 cells, diazinon induced the production of TNF-alpha and IL-6. Diazinon induced ROS generation and the expressions of COX-2, iNOS, and cell-surface molecules CD40, CD86, and MI-IC class II, but reduced phagocytic activity in RAW264.7 cells. ERIC and p38, but not JNK and p65 were involved in diazinon-induced IL-6 expression in RAW264.7 cells. We also examined these proinflammatory responses in bone marrow-derived macrophages (BMDM) and bronchoalveolar lavage fluid (BALF) cells. These results suggested that diazinon can activate macrophages and enhance inflammatory responses. (C) 2017 Elsevier B.V. All rights reserved.

The purpose of this retrospective study was to analyze data in patients with stage IB-IIB uterine cervical cancer who were treated with concurrent chemoradiotherapy (CCRT) with high dose cisplatin and fluorouracil as postoperative adjuvant therapy. Between February 2003 and November 2011, 76 patients with FIGO stage IB-IIB cervical cancer were analyzed. Seventy patients were treated with postoperative CCRT and 6 patients were treated with radiation therapy alone. Data related to overall survival (OS), disease-free survival (DFS), toxicity, and failure pattern were analyzed. The median patient age was 45 years (range, 20-80 years). The median follow-up duration was 63 months (range, 10-125 months). Fifty-eight patients (76.3%) had a squamous cell histologic type, 55 patients (72.4%) had lymphovascular invasion, 31 patients (40.8%) had parametrial invasion, and 28 patients (36.8%) had lymph node metastases. Five-year OS and DFS were 96% and 92%, respectively. Five-year DFS in stage IB1 patients was significantly higher than in stage IB2-IIB patients (p = 0.022). Nineteen patients (25%) had grade 3 or 4 neutropenia, 13 patients (17.1%) had grade 3 anemia, and 2 patients (2.6%) had grade 3 thrombocytopenia, but none of these patients died from the disease. Three patients experienced chronic toxicity: one had bladder perforation, one had hydronephrosis, and one experienced ileus. CCRT as postoperative adjuvant therapy resulted in good survival and outcome without severe toxicity.

Purpose: To evaluate the visualization of middle ear ossicles by ultra-short echo time magnetic resonance (MR) imaging at 3T in subjects over 50 years old.
Materials and Methods: Sixty ears from 30 elder patients that underwent surgical or interventional treatment for neurovascular diseases were included (ages: 50-82, median age: 65; 10 men, 20 women). Patients received follow-up MR imaging including routine T1-and T2-weighted images, time-of-flight MR angiography, and ultra-short echo time imaging (PETRA, pointwise encoding time reduction with radial acquisition). All patients underwent computed tomography (CT) angiography before treatment. Thin-section source CT images were correlated with PETRA images. Scan parameters for PETRA were: TR 3.13, TE 0.07, flip angle 6 degrees, 0.83 x 0.83 x 0.83 mm resolution, 3 min 43 s scan time. Two radiologists retrospectively evaluated the visibility of each ossicular structure as positive or negative using PETRA images. The structures evaluated included the head of the malleus, manubrium of the malleus, body of the incus, long process of the incus, and the stapes. Signal intensity of the ossicles was classified as: between labyrinthine fluid and air, similar to labyrinthine fluid, between labyrinthine fluid and cerebellar parenchyma, or higher than cerebellar parenchyma.
Results: In all ears, the body of the incus was visible. The head of the malleus was visualized in 36/60 ears. The manubrium of the malleus and long process of the incus was visualized in 1/60 and 4/60 ears, respectively. The stapes were not visualized in any ear. Signal intensity of the visible structures was between labyrinthine fluid and air in all ears.
Conclusion: The body of the incus was consistently visualized with intensity between air and labyrinthine fluid on PETRA images in aged subjects. Poor visualization of the manubrium of the malleus, long process of the incus, and the stapes limits clinical significance of middle ear imaging with current PETRA methods.
