Objectives: This study aimed to describe the experiences of bereaved family members of cancer patients in terms of regret in relation to ending terminal treatment for the patient. Methods: We conducted a semi-structured qualitative interview of 37 bereaved family members regarding their decision-making and their psychological adjustment from the time they made the decision to terminate treatment. Interviews were analyzed using qualitative content analysis. Results: Approximately 40% of bereaved family members reported that they had some regrets about their decision. Regret contents were classified into 8 categories and diversified from 4 categories at the time of decision-making to 7 categories after the death. The reasons for regret were classified into 43 categories. Common factors that minimized regret included situations at the time when they made the decision, such as patient- and family-specific factors and relationship with the medical staff. In comparison, the common reasons for regret centered on factors related to the approach for decision-making, such as the process, options, as well as psychological coping and relationships with medical staff. Conclusion: The results suggest that regret in the bereaved could be modified by understanding the relationship between regret characteristics and psychological coping.

Quercetin, a flavonoid, widely distributed in many fruits and vegetables, is well known to have an anti-tumor effect despite its mutagenicity. In this study, we examined the effect of dietary quercetin on duodenum-tumorigenicity of mice induced by a chemical carcinogen, N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG). Eight-week-old male C57BL/6 mice were divided into 4 groups; ENNG without quercetin (group A), ENNG with 0.2% quercetin (group B), ENNG with 2% quercetin (group C), and 2% quercetin without ENNG (group D). ENNG was given in drinking water for the first 4 weeks, and thereafter quercetin was given in a mixed diet. At week 20, the average number of duodenal tumors per mouse was significantly higher in group C (mean±SE, 7.26±1.75, p<0.05) than in group A (2.32±0.31). The size of the duodenal tumors increased significantly in group B (1.79±0.09 mm, p<0.001) compared with group A (1.43±0.09 mm). In contrast, no duodenal tumor was induced in group D. The present findings suggest that excessive intake of quercetin occasionally is a risk factor for carcinogenesis of some specific organs such as the upper intestine.

History of Mongolian medicine could be traced back to 2000 years ago. Mongolian traditional medicine has been built over many years. We traveled Mongolia to visit a hospital and a private clinic where traditional Mongolian medicine is in practice, and visited National University of Medical Sciences. In this paper, we report the current status of traditional medicine in Mongolia. We visited Mongolian National University of Medical Sciences and conversed with the president, vicepresident, and director of the traditional medical department. We visited a clinic where Mongolian traditional medicine is performed and a hospital where mainly traditional therapies and practical development are carried out. In the hospital, they mainly provide acupuncture and moxibustion treatment, cupping therapy, herbal therapy, and thermotherapy. It cannot be denied that moxibustion treatment came from Mongolia, because it is also said that ‘the north' in “Huangdi Neijing Suwen” chapter 12 means Mongolia. However, as there is a background once traditional medicine has been kept away from the national health care system, it is difficult to find a specific medical practice for Mongolian medicine as far as we have viewed the present status of medical practice in Mongolia. Considering that the cultural exchange with Japan is being carried out in many other fields, we expect that a number of new facts will come to light in the near future.

The purpose of this study was to clarify feasibility of a booklet for families of children dying with incurable cancer. Of 267 pediatric oncology specialists, 76 (28%) participated in this cross-sectional survey. Ninety-three percent of participants answered that they were “likely to use” the booklet, and 86% percent answered that they believed the booklet was “helpful” for families. Some participants described various advantages of its use as follows: “able to communicate something that is difficult to put into words,” “easy to understand for families,” “families can read whenever they choose to,” and “able to grasp the direction of dying.” In contrast, other participants described points of attention of use as follows: “optimal timing to bring out,” “acceptance of families,” “direction as interdisciplinary team,” “confidential relationship between families and interdisciplinary team,” “disinclination among health care providers,” and “information volume of the booklet.” Thus, our results validated feasibility of the booklet. In conclusion, pediatric oncology specialists should provide their support of utilizing the booklet for families and assessing each family condition and advantage/attention of using the booklet.
