In commercializing the superconducting Maglev system it is important to reduce the cost, especially that of ground coils constructed along the whole length of the guideway. For this purpose we have examined the combined propulsion, levitation and guidance system (PLG system) which can generate levitation, guidance and propulsion, forces by the same coil. This paper describes the test run of the PLG system, whose ground coils (PLG coil) are constructed in one part of the Miyazaki test track. In designing the PLG coil, we make clear the magnitudes of the force acting both under normal and unusual conditions because the electromagnetic force, which levitates, guides, and propels the vehicle, directly acts on the magnet winding of the PLG coil. In the experiment, we examine both the performance of the vehicle and the force of a PLG coil. The measurement of the force at the PLG coil gives not only propulsion force and levitation force directly, but also guidance stiffness by sifting the measured coil. Good correlation recognized between the calculation and the experiment in the propulsion force, levitation force, and guidance stiffness proves that the required characteristics can be expected from the PLG system even under combination of propulsion, levitation and guidance.

- Abstract
Background and Aim: Although previous studies compared the efficacy of infliximab (IFX) versus adalimumab (ADA) as the first-line biologics for Crohn's disease (CD), the difference in long-term prognosis based on which biologic was used first has scarcely been reported. In particular, the clinical courses after loss of response (LOR) of the first-line biologics are largely unknown., Methods: A multicenter, retrospective study was performed. Disease courses of biologic-naïve CD patients who were started on IFX or ADA treatment were evaluated, even after LOR of the initial biologics., Results: In total, 263 CD patients were eligible for analysis, 183 were treated with IFX first, and 80 were treated with ADA first. The median observation period was 64.2 months. The cumulative steroid-free remission rates and surgery-free rates did not differ significantly between the patients treated with IFX first and those treated with ADA first (log-rank test P = 0.42 and P = 0.74, respectively). In addition, no significant difference was observed in the rate of occurrence of events associated with ineffectiveness (modification of anti-tumor necrosis factor treatment including intensification, switch, discontinuation, or surgery) between the patient groups (log-rank test P = 0.62). The patients treated with IFX first were likely to discontinue the agent due to adverse events, whereas those treated with ADA first were likely to discontinue due to treatment failure or LOR., Conclusions: No significant difference was observed in the long-term prognosis between biologic-naïve patients with CD who were started treatment with IFX first and ADA first., (© 2019 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

- Abstract
A randomised, double-blind, phase II, dose escalation trial was conducted to assess the safety, tolerability and pharmacokinetics of the tyrosine kinase inhibitor nintedanib, alone and when added to ongoing pirfenidone therapy, in Japanese patients with idiopathic pulmonary fibrosis. 50 Japanese patients were randomised to receive nintedanib or placebo in one of three cohorts (nintedanib 50 mg twice daily or 100 mg twice daily for 14 days, or 150 mg twice daily for 28 days). Patients receiving pirfenidone at inclusion were stratified to every nintedanib dose group and placebo. Adverse events were reported in nine out of 17 patients receiving nintedanib alone and 10 out of 21 patients receiving nintedanib added to pirfenidone. All adverse events were mild or moderate in intensity. Gastrointestinal disorders were the most common adverse event. Maximum plasma concentration and area under the curve at steady state for nintedanib and its metabolites tended to be lower when nintedanib was added to pirfenidone. Nintedanib had no effect on the pharmacokinetics of pirfenidone. In conclusion, further study is needed to evaluate the safety and tolerability profile of nintedanib when added to pirfenidone in patients with idiopathic pulmonary fibrosis. There was a trend toward lower exposure of nintedanib when it was added to pirfenidone., (Copyright ©ERS 2015.)

- Abstract
Background: Although the number of ulcerative colitis patients has increased rapidly in Japan, few reports have been published regarding their clinical aspects. We investigated the clinical characteristics and chronological change of ulcerative colitis in Japanese patients., Methods: Patients diagnosed with ulcerative colitis during the period from 1981 to 2000 were registered and their clinical profiles were analyzed. The chronological changes in clinical aspects, such as onset age, sex distribution, severity, extent of disease, clinical course, and corticosteroid use, were also determined., Results: A total of 844 patients were registered, composed of 431 men and 413 women, with a median onset age of 34 years. The proportion of mild colitis and proctitis was significantly larger in patients with an onset at over 60 years of age, relative to those with an onset at less than 30 years (P<0.016). The proportion of ulcerative colitis patients with old age onset (P=0.09), male sex (P<0.01), mild colitis (P<0.01), proctitis (P<0.01), one-attack-only type (P<0.01), and not-treated-with-corticosteroid (P<0.01) demonstrated a chronological increase from 1981 to 2000., Conclusions: The distinctive clinical features and chronological change were seen in Japanese ulcerative colitis patients in recent years. Our data can help understand clinical aspects of ulcerative colitis patients in Asia, where the incidence of ulcerative colitis is still increasing.
