We, the delegates of the 2016 Japan-UK exchange, herein report our experiences and impressions of British primary care: "the difference between the career paths of general practitioners from Japan and UK", "medical interpreters and care in a multicultural society" and "framework for development of clinical research". We described our experiences in UK with a literature review. The authors wish for the article to support the advancement of Japanese primary care.

The aim of this study was to demonstrate a time-series relationship in drop jump (DJ) from a pre-set state with improved performance. Twelve male college athletes performed a DJ from a height of 0.60 m. DJ performance was assessed with a DJ-index (jump height/contact time). Short-interval intracortical inhibition (SICI) was assessed as intracortical inhibitory circuit excitability in a pre-set state, calculated by using paired-pulse transcranial magnetic stimulation for the medial gastrocnemius muscle (MG). The H-reflex of the left MG and the ankle joint torque were calculated in the early phase of take-off. A significant correlation was shown between ⊿SICI during the pre-set state and the DJ index. Thus, we examined the relationships between phases, focusing on time-series relationships throughout the jump period. The results showed a significant correlation between ⊿SICI during the pre-set state and %H-reflex during the early phase of take-off, and peak ankle joint torque during take-off was also significantly correlated with %H-reflex during the early phase of take-off. A significant correlation was also demonstrated between ankle joint torque during take-off and the DJ-index. In conclusion, we observed a time-series relationship between DJ from a pre-set state and improved performance. A decrease of intracortical inhibitory circuit excitability in the pre-set state affects stretch-reflex facilitation during the early phase of take-off; stretch-reflex facilitation results in the development of a large force in the ankle joint during take-off, and this force develops ankle joint torque. These findings may be used to improve jump performance.

Objective
  The authors were engaged in an adolescent peer leader project. While the main target of this peer education was adolescent students, evaluation of a ripple effect on local residents is a necessary step for the development of peer education activities. Accordingly, the object of this study was to assess whether adolescent peer education had improved the health consciousness and knowledge of the local residents of a rural area of Mexico.
Method
  The subjects were residents aged between 12 and 69 years living in the districts covered by 3 public health centers in the Poza Rica district, Veracruz State. A list of residents in this age group was prepared, and 50% of all the households in each area were randomly selected. From March to April 2010, before the start of the activities, an interview survey was conducted.
Results
  Regarding the question on self-esteem, the percentage of respondents who reported being as capable as most other people significantly increased (p < 0.001). On lifestyle, the percentage of people who reported consuming vegetables and fruits daily or once in 23 days significantly increased (p < 0.001). Regarding knowledge about STDs and contraception, the rate of correct answers about STDs decreased in the second measurement, while the percentage of correct answers about contraception significantly increased. On peer education, the percentage of people who had heard of the term “peer educator” significantly increased (p < 0.001).
Conclusion
  The current adolescent peer education activity undertaken in a rural area of Mexico improved self-esteem and health consciousness in other residents of the community. The ripple effect on the entire community was limited for knowledge of STDs and contraception. However it was suggested that the increase of motivation for attendance to health education in the community could be a stepping stone to the spread of knowledge.

In February 2017, general practitioners (GPs) from the Department of Community and Family Medicine of Fukushima Medical University in Japan visited Australia for a study tour where the tour participants met with local GPs, GP registrars and researchers. During this tour, we visited public hospitals and observed multiple GPs providing community-based health care. We also attended a new GP registrars' orientation where the two authors gave a presentation about the current status of primary care in Japan. We then visited an Aboriginal health research center, and learned about the cultural values of the Aboriginal people and the challenges of implementing large-scale cohort studies.

Background: and Purpose Differences in measurement of the extent of acute ischemic stroke using the Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) by non-contrast computed tomography (CT-ASPECTS stratum) and diffusion-weighted imaging (DWI-ASPECTS stratum) may impact the efficacy of endovascular therapy (EVT) in patients with a large ischemic core. Methods: The RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism Japan–Large IscheMIc core Trial) was a multicenter, open-label, randomized clinical trial that evaluated the efficacy and safety of EVT in patients with ASPECTS of 3–5. CT-ASPECTS was prioritized when both CT-ASPECTS and DWI-ASPECTS were measured. The effects of EVT on the modified Rankin Scale (mRS) score at 90 days were assessed separately for each stratum. Results: Among 183 patients, 112 (EVT group, 53; No-EVT group, 59) were in the CT-ASPECTS stratum and 71 (EVT group, 40; No-EVT group, 31) in the DWI-ASPECTS stratum. The common odds ratio (OR) (95% confidence interval) of the EVT group for one scale shift of the mRS score toward 0 was 1.29 (0.65–2.54) compared to the No-EVT group in CT-ASPECTS stratum, and 6.15 (2.46–16.3) in DWI-ASPECTS stratum with significant interaction between treatment assignment and mode of imaging study (P=0.002). There were significant interactions in the improvement of the National Institutes of Health Stroke Scale score at 48 hours (CT-ASPECTS stratum: OR, 1.95; DWIASPECTS stratum: OR, 14.5; interaction P=0.035) and mortality at 90 days (CT-ASPECTS stratum: OR, 2.07; DWI-ASPECTS stratum: OR, 0.23; interaction P=0.008). Conclusion Patients with ASPECTS of 3–5 on MRI benefitted more from EVT than those with ASPECTS of 3–5 on CT.

Abstract A large rubella epidemic is currently ongoing since 2018 in Osaka, Japan. The detected rubella viruses were classified into genotypes 1E lineage 2 and 2B lineage 1. These strains may have been imported from endemic countries, and these viruses spread within the susceptible population.
