The 60MWh vanadium flow battery system was installed in Minami-Hayakita substation of Hokkaido Electric Power Co., Inc. (HEPCO), and started operation December 2015, to demonstrate application of the storage battery as a dispatchable power source like fire plants and hydro plants. In commissioning tests, initial characteristics of the flow battery system, such as energy capacity, system efficiency, and response time, are confirmed. These results satisfied the specification of the system. This system has been operated to demonstrate various types of control modes such as load frequency control, compensation for wind power and PV output fluctuation, control for countermeasure against over generation, and so on. In periodic evaluation, it is confirmed that there is no deterioration of energy capacity and system efficiency, which are main performance parameters, for these 2 years of operation.

Management of nausea is an important dimension of palliative care. The first choice for treating nausea is antiemetics, but their efficacy is inadequate. Acupressure intervention for nausea in cancer patients has been studied as a non-pharmacological therapy, and appears to have had some effect. However, such a therapy has not been well reviewed in patients with terminal cancer. The purpose of this study was to clarify the feasibility of acupressure intervention and examine its safety and preliminary efficacy. We recruited cancer patients that fulfilled the eligibility criteria and were admitted to the palliative care unit, from August 2018 to February 2019, in Tohoku University Hospital, Japan. We conducted a longitudinal assessment of acupressure intervention in a single arm. We identified the patient’s research accomplishments and evaluated possible fainting due to the vagal reflex and symptom severity. Descriptive statistics were used to calculate the completion rate for the feasibility and Wilcoxon signed-rank tests to compare the average of continuous variables for the safety and efficacy. Twelve patients participated in this study and completed the procedure. Their average age was 70 years (SD = 9.3), and the most common primary cancer sites were the rectum and pancreas. The blood pressure and pulse rate did not drop sharply. Four patients exhibited decreased nausea but there was no statistically significant difference (P = 0.5). We suggested that acupressure has high feasibility and safety, as an intervention for patients with terminal cancer. However, no significant differences were observed regarding its effect on nausea.

Providing spiritual care in light of a patient’s religious and/or spiritual background can help improve the quality of end-of-life care. Rinsho-shukyo-shi is a Japanese interfaith chaplain who provides religious and spiritual care to patients. In this study, we qualitatively explore the impressions of patients in a palliative care unit of the activities of an interfaith chaplain in a hospital in Japan. The authors used semi-structured interviews carried out by a male nurse experienced in qualitative and quantitative research in palliative care. The male nurse asked only a few predetermined questions in the interviews, which were conducted from January 19 to December 26, 2018. The interviewees were 15 patients diagnosed with advanced cancer (five men and 10 women; aged 53-81 years), and they were admitted to the palliative care unit of Tohoku University Hospital (the hospital has no religious affiliation). Patients who had spoken to the interfaith chaplain at the hospital at least twice were included in the study. The interviews were digitally audio-recorded, transcribed verbatim, and analyzed. Three main themes were identified through thematic analysis. Resistance varied across patients; no patient felt resistance to the intervention by, or to the presence of, the interfaith chaplain once he/she had spoken with him. Opinions about the interfaith chaplain also varied, with 10 patients claiming that his role was necessary for end-of-life care and beneficial for the chaplain himself. Finally, the patients’ religious beliefs varied widely. In conclusion, the interfaith chaplain is deemed helpful by the interviewed patients in relieving their anxieties.

Introduction The early integration of palliative care into standard cancer treatment has become a global standard. The Palliative care Emphasis program on symptom management and Assessment for Continuous medical Education (PEACE) has been conducted in Japan, and previous studies have reported that the PEACE workshop was able to improve various palliative care skills of participants. However, whether or not the effects of the program are long-lasting and if the program consequently changed physicians' practice with regard to lung cancer patients have been unclear. Methods Web-based surveys, including the palliative care knowledge test (PEACE-Q), the Palliative Care self-reported Practice Scale (PCPS), and the Palliative Care Difficulties Scale (PCDS), were conducted among lung cancer physicians in Japan. The differences in the survey results between participants and non-participants of the PEACE workshop were examined. Results Among 923 respondents (455 respiratory physicians, 345 pulmonary surgeons, and 123 others), 519 had participated in the PEACE workshop. The total PEACE-Q score was significantly higher in the PEACE workshop participants than in non-participants (28.0 versus 24.5, p<0.0001). The score was significantly higher in respiratory physicians than in pulmonary surgeons (27.4 versus 25.5). The total PCPS and PCDS scores were also significantly better in workshop participants than in non-participants (71.8 versus 67.1 and 34.3 versus 36.9, respectively), although some domains of PCDS were similar between the groups. Conclusion The PEACE program improved the knowledge and practices with regard to palliative care and resolved difficulties associated therewith among lung cancer physicians. In regions where palliative care specialists are insufficient, such educational programs may be effective. Mini Abstract The PEACE program improved the knowledge and practices with regard to palliative care and resolved difficulties associated therewith among lung cancer physicians in Japan.
