A new species of penaeid, Metapenaeus motohi sp. nov. is described based on material from the Philippines. This new species is most closely similar to M. ensis (De Haan, 1844) from Japan in the morphology of the thelycum, but differs in that the rostral teeth mostly number 8-9, the P2, P3, and P5 are elongate, and the distal portion of the petasma forms a narrow lobule with a small genital pore.

This paper explores how what I call 'administrative categories' have been adopted by the Japanese government and experts in autism support and what roles these categories have played in local settings. Since support practices for children and adults with autism began in the 1950s in Japan, the Japanese government and people engaging in autism support have used Japanese-specific administrative categories, instead of relying on a medical concept of autism, such as 'severe moving disabilities' (SMD), 'emotional disturbance', and 'extremely disruptive behavioural disorders' (EDBD). To understand the emergence of these three autism-related administrative categories in Japan, historical materials published from the 1950s to the 1990s by Japanese authors (doctors, psychologists, teachers, educationalists, welfare workers, government officials, and parents) and interview data with 19 leading experts of autism in Japan were collected and analysed thematically. The analysis revealed that the governmental ministries aimed to focus on establishing administrative support by avoiding engaging in aetiological debates among doctors, and to describe the political agenda more vividly. Administrative categories filled the gap between local interests and international medical concepts, enabling the concept of autism to be rooted in Japan's administrative systems. Three roles of administrative categories were identified: i) separation from medicine, ii) describing local problems, and iii) claimsmaking to wider actors and the public. I concluded that looking purely at medical and specifically diagnostic concepts limits our understanding of the formation of practices regarding disabilities, and thus more focus should be placed on categorisation practices outside of medicine. In addition, to the literature on the globalisation of Euro-American psychiatric concepts, this study contributes to our knowledge of a form of locality that has not been central in the exploration of the influence of globalisation on local settings and the relationships between the local and the global., Competing Interests: Declaration of competing interest The author declares that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author.

Background: In Japan, approximately half of all lung cancer patients are aged > 75 years, and the proportion of older patients is increasing. In older patients, it is necessary to consider comorbidities and concomitant drug use to ensure optimal cancer treatment; however, geriatric assessment (GA) is not widely performed. We plan to conduct a study (ENSURE-GA) of GA in older lung cancer patients to determine whether GA with intervention improves patient satisfaction with their treatment., Methods: The study will be a phase III comparative clinical trial with a cluster-randomized design, and it will be conducted at 81 sites distributed throughout Japan. Approximately 1000 lung cancer patients aged ≥ 75 years will be enrolled in the study. All participants will undergo a standardized GA before starting treatment (using an iPad). At the intervention sites, the GA results and intervention method recommended on the basis of the GA results will be returned as an instant report to guide the physician's choice of intervention. At the control sites, the physician will decide on interventions based on standard practice. All participants will complete a patient satisfaction survey before treatment initiation (after the GA) and 3 months later., Discussion: The purpose of the ENSURE-GA study is to evaluate whether GA with interventions improves patient satisfaction with treatment outcomes. The study may lead to the increased use of GA and improved treatment of cancer in older adults. The results will also be used to prepare guidelines for treating older cancer patients and will provide a foundation for the development of a standardized geriatric oncology system., Trial Registration: The study has been registered in the University Hospital Medical Information Network database (no. UMIN000037590). The registration date is August 4, 2019, and the protocol version is 2.0. ( https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000042853 .).

We, 4 authors, visited 4 surgical centers in the United States last year on a tour sponsored by the Japanese Association for Operative Medicine. The surgical center of each hospital we visited aimed to contribute to the hospital not only in terms of financial strength but also in the creation of a unique hospital brand value by increasing the number of surgeries compared with previous years as much as possible. The role of surgical centers in the United States was comparable with what we consider an ideal center in Japan. We also found that management of the surgical centers by directors who are specialized anesthesiologists is well organized to promote efficiency with respect to organization, utilities and human resources, and realized that these anesthesiologists must know how to manage the team members and the organization of the surgical centers to improve the quality of operative medicine.

We examined the relation of serum lipids and apolipoprotein E genotype to colorectal adenomas among 205 cases and 220 controls with normal colonoscopy in Japanese men. With adjustment for body mass index, cigarette smoking, alcohol use, and other covaiates, odds ratios of proximal and distal adenomas associated with the presence of an allele varepsilon4 were 0.59 (95% confidence interval 0.23-1.45) and 0.99 (0.50-1.98), respectively. While serum total and LDL cholesterol were unrelated to both proximal and distal adenomas, serum triglycerides were positively related to distal adenomas. The findings suggest that altered lipid metabolism may be differentially associated with tumorigenesis in the proximal and distal colorectum.

A homozygous mutation at bp 677 in the gene for the methylenetetrahydrofolate reductase (MTHFR) was previously shown to be associated with a decreased risk of colorectal cancer. We examined the relation between the MTHFR genetic polymorphism and risk of colorectal adenoma in Japanese men using 205 cases of colorectal adenomas and 220 controls of normal total colonoscopy. The homozygous mutation was not measurably associated with colorectal adenomas. The findings corroborate the lack of an association between the MTHFR genotype and colorectal adenomas, but do not deny the possibility that the genotype may be involved in the late stage of colorectal carcinogenesis.
