タイトル: Effect of no cost sharing for paediatric care on healthcare usage by household income levels: regression discontinuity design著者: Fukuma, Shingo; Kato, Hirotaka; Takaku, Reo; Tsugawa, Yusuke抄録: OBJECTIVES: To investigate the impact of no cost sharing on paediatric care on usage and health outcomes, and whether the effect varies by household income levels. Design: Regression discontinuity design. SETTING: Nationwide medical claims database in Japan. PARTICIPANTS: Children aged younger than 20 years from April 2018 to March 2022. EXPOSURE: Co-insurance rate that increases sharply from 0% to 30% at a certain age threshold (the threshold age varies between 6 and 20 years depending on region). PRIMARY OUTCOME MEASURES: The outpatient care usage (outpatient visit days and healthcare spending for outpatient care) and inpatient care (experience of any hospitalisation and healthcare spending for inpatient care). RESULTS: Of 244 549 children, 49 556 participants were in ...

タイトル: Identification of complications requiring interventions after gastrointestinal cancer surgery from real-world data: An external validation study著者: Kinoshita, Hiromitsu; Nishigori, Tatsuto; Kunisawa, Susumu; Hida, Koya; Hosogi, Hisahiro; Inamoto, Susumu; Hata, Hiroaki; Matsusue, Ryo; Imanaka, Yuichi; Obama, Kazutaka; Matsumura, Yumi抄録: Background: Recently, real-world data have been recognized to have a significant role for research and quality improvement worldwide. The decision on the existence or nonexistence of postoperative complications is complex in clinical practice. This multicenter validation study aimed to evaluate the accuracy of identification of patients who underwent gastrointestinal (GI) cancer surgery and extraction of postoperative complications from Japanese administrative claims data.; Methods: We compared data extracted from both the Diagnosis Procedure Combination (DPC) and chart review of patients who underwent GI cancer surgery from April 2 ...

Title: Effect of an ultrathin Fe interlayer on the growth of MnGa and spin-orbit-torque induced magnetization switchingAuthors: Ogawa, Mineto; Hara, Takuya; Hasebe, Shun; Yamanouchi, Michihiko; Uemura, TetsuyaAbstract: We investigated the effect of an ultrathin Fe interlayer on the growth of MnGa and spin-orbit torque (SOT) induced magnetization switching. MnGa was epitaxially grown on Fe at room temperature without thermal annealing. The MnGa/Fe bilayer was perpendicularly magnetized, and clear magnetization switching of the MnGa/Fe bilayer using the spin current, mainly from the adjacent Ta, was observed. The insertion of the Fe layer reduced the switching current density and increased a SOT-originated effective magnetic field. These results indicate that the MnGa/Fe bilayer is a promising spin source, capable of both perpendicular spin injection into GaAs and electrical manipulation of its spin direction.
