Emerging topics on basic research in hypertension: interorgan communication and the need for interresearcher collaboration.

The pathogenesis of hypertension is multifactorial and highly complex. Basic research plays critical roles in elucidating the complex pathogenesis of hypertension and developing its treatment. This review covers recent topics in basic research related to hypertension in the following six parts: brain/autonomic nervous system, kidney, vascular system, potential treatments, extracellular vesicles, and gut microbiota. The brain receives afferent nerve inputs from peripheral organs, including the heart, kidneys, and adipose tissue, and humoral inputs from circulating factors such as proinflammatory cytokines and leptin, which are involved in the regulation of central sympathetic outflow. In the kidneys, changes in Wnt/ß-catenin signaling have been reported in several hypertensive models. New findings on the renin-angiotensin-aldosterone system in the kidneys have also been reported. Sirtuin 6, which participates in various cellular functions, including DNA repair, has been shown to have protective effects on the vascular system. Skin water conservation, mediated by skin vasoconstriction and the accumulation of osmolytes such as sodium, has been found to contribute to hypertension. Studies of rivaroxaban and sodium-glucose cotransporter-2 inhibitors as drug repositioning candidates have been performed. Extracellular vesicles have been shown to be involved in novel diagnostic approaches and treatments for hypertension as well as other diseases. In gut microbiota studies, interactions between microbiota and antihypertensive drugs and potential pathophysiology linking microbiota and COVID-19 have been reported. It can be seen that inter-organ communication has received particular attention from these recent research topics. To truly understand the pathogenesis of hypertension and to develop treatments for conquering hypertension, interresearcher communication and collaboration should be further facilitated. This mini-review focuses on recent topics on basic research in hypertension from the several points of view. The recent topics indicate that inter-organ communication has received particular attention. Interresearcher communication and collaboration should also be further facilitated to truly understand the complex pathogenesis of hypertension and to develop the treatments.

Evaluation of a Webinar for Pharmacists Learning Basic Clinical-Oncology during COVID-19 Pandemic in Japan.

It is essential for oncology pharmacists to update their knowledge, skills, and ethical attitudes. The Japanese Society of Pharmaceutical Oncology is an academic society for healthcare professionals involved in cancer treatment. It has conducted in-person seminars every year to cultivate the knowledge necessary for practicing advanced cancer medicine. Owing to the coronavirus disease (COVID-19) pandemic, the society was obligated to conduct a web-based seminar this year. A questionnaire survey was conducted before and after the webinar to explain how it works and to assess the learning attitudes of beginner and moderately skilled pharmacists in the field of oncology. Questionnaire surveys were conducted with the participants before and after watching the webinar. The questionnaires sought to determine participants' perspectives on the webinar and their knowledge of the seven modules. Of the 1756 webinar attendees, 1661 (94.6%) answered the pre-webinar survey and 1586 (90.3%) answered the post-webinar survey. Results indicate that the median post-webinar knowledge score was significantly higher than the median pre-webinar score (p < 0.001) in all modules. Principal component analysis of the degree of knowledge of seven modules revealed that the improved score group consisted of those from younger age groups, with less experience as pharmacists, non-society members, and those with less experience in past society seminars. Moreover, the web-based seminar provided a uniform learning effect throughout the country without distinguishing between urban and rural learners. The web-based educational program was an acceptable educational tool for Japanese oncology pharmacists.

Evaluation of a web-based educational programme for pharmacists during the COVID-19 pandemic in Japan.

WHAT IS KNOWN AND OBJECTIVE: Continuing education is essential for pharmacists to acquire and maintain the knowledge, skills, and ethical attitudes necessary for clinical practice. However, with the emergence of COVID-19, the social circumstances and face-to-face learning environments have changed. The objectives of this study were to determine Japanese pharmacists' perception of a web-based educational programme in oncology, and assess changes in their understanding of pharmaceutical care in oncology before and after their participation in the webinar. METHODS: Questionnaire-based surveys were conducted for the participants of the web-based educational programme to determine their perspectives on the webinar, and their degree of comprehension of the five cancer types covered before and after watching the webinar. RESULTS AND DISCUSSION: Of the 1936 pharmacists taking the programme, all participated in the pre-webinar survey, and 1861 (96.1%) in the post-webinar survey. Compared with previous seminars that were held in the offline mode before the COVID-19 pandemic, 76.8% of respondents were significantly satisfied with the web-based educational programme. The median post-webinar comprehension scores in all modules were significantly higher than the median pre-webinar scores (p < 0.0001). A majority of the participants agreed that a web-based educational programme was satisfactory in acquiring knowledge. WHAT IS NEW AND CONCLUSION: This web-based educational programme was effective for Japanese pharmacists for postgraduate education in pharmaceutical care in oncology. To the best of our knowledge, our study is the first to report the effectiveness of a web-based educational programme for oncology pharmacists using a large population.
