Species of the Maera-clade collected from Japan. Part 4: addenda to genera Maera Leach, 1814 and Quadrimaera Krapp-Schickel Ruffo, 2000, with revised keys to Japanese species of the clade (Crustacea: Amphipoda: Maeridae).

Two new species of Maera Leach, 1814 and Quadrimaera Krapp-Schickel Ruffo, 2000 included in the Maera-clade are described from Japan. Maera denticoxa sp. nov. was collected from Iwate and Hokkaido Prefectures and can be distinguished from its congeners by the small notches on the posteroventral margins of coxae 1-6. Quadrimaera angulata sp. nov. from north of Tanegashima Island in Kagoshima Prefecture is characterized by the distal tooth on the mandibular palp article 1, the rounded palm of the female gnathopod 2, and the angular posterodistal margin of the pereopod 7 basis. Keys to Japanese species of the Maera-clade are provided. In total, seventeen species included in the clade occur in Japan.

A randomised controlled trial of a case management approach to encourage participation in colorectal cancer screening for people with schizophrenia in psychiatric outpatient clinics: study protocol for the J-SUPPORT 1901 (ACCESS) study.

INTRODUCTION: One of the reasons for the high mortality rate from cancer in people with schizophrenia is delay in diagnosis. Many studies have shown lower cancer screening rates in people with schizophrenia; however, there are no interventions for people with schizophrenia to increase cancer screening. Therefore, we developed a case management (CM) intervention to encourage participation in cancer screening. The purpose of this study was to examine the efficacy of CM to encourage participation in cancer screening for people with schizophrenia, with particular focus on colorectal cancer screening by faecal occult blood testing, compared with usual intervention (UI), namely, municipal public education. METHODS AND ANALYSIS: This is an individually randomised, parallel group trial with blinded outcome assessments. The participants will be randomly allocated to either the CM plus UI group or UI alone group in a 1:1 ratio using a web-based program at a data management centre. The primary end point of the study is participation in colorectal cancer screening in the year of intervention, which will be assessed based on municipal records. ETHICS AND DISSEMINATION: This study is performed in accordance with Ethical Guidelines for Medical and Health Research Involving Human Subjects published by Japan's Ministry of Education, Science, and Technology and the Ministry of Health, Labour, and Welfare and the modified Act on the Protection of Personal Information as well as the Declaration of Helsinki. This study was approved by the institutional ethics committee at the Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital on 23 April 2019 (approval number: RIN1904-003). The findings of this trial will be submitted to an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: UMIN000036017.
