These results suggested that OPN is related to the proliferation and regeneration of tubular epithelial cells after tubular damage.

These data suggest that inducible expression of OPN in the tubular epithelium may have a pathogenic role in acute renal allograft rejection by mediating interstitial monocyte infiltration and possibly tubular regeneration.

IntroductionGiven the shortage of physicians, particularly in rural areas, the Japanese government has rapidly expanded the number of medical school students by adding chiikiwaku (regional quotas) since 2008. Quota entrants now account for 17% of all medical school entrants. Quota entrants are usually local high school graduates who receive a scholarship from the prefecture government. In exchange, they temporarily practise in that prefecture, including its rural areas, after graduation. Many prefectures also have scholarship programmes for non-quota students in exchange for postgraduate in-prefecture practice. The objective of this cohort study, conducted by the Japanese Council for Community-based Medical Education, is to evaluate the outcomes of the quota admission system and prefecture scholarship programmes nationwide.Methods and analysisThere are 3 groups of study participants: quota without scholarship, quota with scholarship and non-quota with scholarship. Under the support of government ministries and the Association of Japan Medical Colleges, and participation of all prefectures and medical schools, passing rate of the National Physician License Examination, scholarship buy-out rate, geographic distribution and specialties distribution of each group are analysed. Participants who voluntarily participated are followed by linking their baseline information to data in the government's biennial Physician Census. Results to date have shown that, despite medical schools' concerns about academic quality, the passing rate of the National Physician License Examination in each group was higher than that of all medical school graduates.Ethics and disseminationThe Ethics Committee for Epidemiological Research of Hiroshima University and the Research Ethics Committee of Nagasaki University Graduate School of Biomedical Sciences permitted this study. No individually identifiable results will be presented in conferences or published in journals. The aggregated results will be reported to concerned government ministries, associations, prefectures and medical schools as data for future policy planning.

Purpose To show the practice location of graduates from two Japanese programs recruiting physicians to rural areas: a regional quota program of medical schools and a prefecture scholarship program (a prefecture is an administrative geographic division). Graduates of each program must work in a designated rural prefecture for a fixed period. Method A nationwide cohort study was conducted for three groups of participants graduating between 2014 and 2016: quota graduates without scholarship (quota alone), nonquota graduates with scholarship (scholarship alone), and quota graduates with scholarship. A questionnaire was sent via medical school or prefecture office to each potential subject to collect baseline individual data, including home prefecture and graduation year. Data were connected through physician identification number to the Physician Census 2016 of the Ministry of Health, Labour and Welfare to identify the subjects’ practice location and compared with data for other physicians in the census. Comparisons were conducted with Mann-Whitney and chi-square tests. Results The proportion of physicians working in nonmetropolitan municipalities for quota alone (185/244; 75.8%), scholarship alone (305/363; 84.0%), and quota with scholarship (341/384; 88.8%) was significantly higher than for other physicians (13,299/22,906; 58.1%). Median population density of the municipalities where subjects worked for quota alone (1,042.4 persons per square kilometer), scholarship alone (613.5), and quota with scholarship (547.4) was significantly lower than that for other physicians (3,214.0). These disparities increased with number of years since graduation. Conclusions The regional quota and prefecture scholarship programs succeeded in producing physicians who practiced in rural areas of Japan.

ObjectivesResponding to the serious shortage of physicians in rural areas, the Japanese government has aggressively increased the number of entrants to medical schools since 2008, mostly as a chiikiwaku, entrants filling a regional quota. The quota has spread to most medical schools, and these entrants occupied 16% of all medical school seats in 2016. Most of these entrants were admitted to medical school with a scholarship with the understanding that after graduation they will practise in designated areas of their home prefectures for several years. The quota and scholarship programmes will be revised by the government starting in 2018. This study evaluates the intermediate outcomes of these programmes.DesignCross-sectional survey to all prefectural governments and medical schools every year from 2014 to 2017 to obtain data on medical graduates.SettingsNationwide.ParticipantsAll quota and non-quota graduates with prefecture scholarship in each prefecture, and all the quota graduates without scholarship in each medical school.Primary outcome measuresPassing rate of the National License Examination for Physicians and the percentage of graduates who have not bought out the scholarship contract after graduation.ResultsMost prefectures and medical schools in Japan participated in this study (97.8%–100%). Quota graduates with scholarship were significantly more likely to pass the National License Examination for Physicians than the other medical graduates in Japan at all the years (97.9%, 96.7%, 97.4% and 94.7% vs 93.9%, 94.5%, 94.3% and 91.8%, respectively). The percentage of quota graduates with scholarship who remained in the scholarship contract 3 years after graduation was 92.2% and 89.9% for non-quota graduates with scholarship.ConclusionsQuota entrants showed better academic performance than their peers. Most of the quota graduates remained in the contractual workforce. The imminent revision of the national policy regarding quota and scholarship programmes needs to be based on this evidence.

The incidence of beaking was high, and increased over 2 years, in patients with autoimmune diseases who were taking BPs and glucocorticoids. Regular femoral X-rays are strongly recommended to screen for beaking. Long-term BP/glucocorticoid use was a risk factor for beaking in patients with autoimmune diseases; BP drug holidays should be considered.
