Short sleep duration is a serious problem that not only enhances the risk of various mental and physical disorders, but also affects the productivity in the workplace. However, in terms of studies focused on workers, there are few reports that evaluated sleeping conditions in an objective way. The purpose of this study is to implement sleep health education in the workplace in terms of primary prevention of mental health disorder and then to investigate the subjective and objective effectiveness of the education using self-administered questionnaires (sleep duration, ESS, AIS, PHQ-9, SF-8) and an activity monitor (MTN-210). Study design is a quasi-randomized controlled trial. Sleep health education was provided through three 50-min lectures (total 150 min) as a single cycle for five months in the Intervention group. We obtained baseline data and then six months later. The study analyzed 70 subjects (36 Intervention group, 34 Control group). The weekday sleep duration for the Control group decreased by 12.9 min, whereas that of the Intervention group increased by 14.3 min (difference of 27.2 min), resulting in a significantly increase in score for the Intervention group. The present study suggests that sleep health education may be beneficial for good sleep habits in workers.

Infertility is a well-known late complication in patients receiving hematopoietic stem cell transplantation (HSCT). We previously reported that total body irradiation (TBI) with ovarian shielding reduces the radiation dose to the ovaries to 2.4 Gy – one-fifth of the dose compared to conventional TBI – and preserves fertility without increasing the risk of relapse. Exposure to the uterus and ovaries can reportedly affect pregnancy and childbirth. However, the dose constraint of the uterus that causes infertility remains unknown. Herein, we report the pregnancy and birth outcomes of 2 patients who gave birth following TBI with ovarian shielding and evaluated the dose to the uterus using a dose-volume histogram. Case 1 involved a 30-year-old woman with acute myeloid leukemia who underwent HSCT at 21 years of age with a uterus mean dose (<i>D</i>_mean) of 7.0 Gy. She had a natural pregnancy and elective cesarean section at 38 weeks of gestation due to hypertensive disorders of pregnancy. She gave birth to a normal-birthweight infant. Case 2 involved a 32-year-old woman with T-cell acute lymphoblastic leukemia who underwent HSCT at 30 years of age with a uterus <i>D</i>_mean of 7.6 Gy. Her baby was delivered at full term with normal birthweight. These results indicate that a uterus <i>D</i>_mean between 7.0 and 7.6 Gy does not have a significant impact on pregnancy and delivery with the ovarian function being preserved for patients who received TBI with ovarian shielding after puberty.

The purpose of this study was to describe and consider the process of changes that occurred in nurses' perceptions and practice of patient education through two sessions: a debriefing session on the recovery experience of patients with chronic kidney disease and a study session on the concept of concordance.Methods: This study was conducted based on action research between May 2018 and March 2020. After conducting a debriefing session and a study session for the ward nurses, we interviewed four nurses two times. The contents of the interviews were analyzed qualitatively.Results: The nurses said that the debriefing and study sessions clarified the current problems in patient education, and they were able to reconsider the perspectives of patient education. The nurses "realized that unilateral patient education was a problem," so they "tried to have the patients speak in their own words." Because nurses "tried to listen to the patients without preconceptions and with awareness of the patients' own situations," changes in practice such as "discussing alternatives that fit the patients' life" were observed. Conclusion:Our study suggested that learning about the patient's recuperation experience and being aware of the concordance concept are effective in conducting recuperation assistance for behavior change in patients. 要 旨 目的：2017 年に実施した入退院を繰り返す保存期慢性腎臓病患者 11 名の療養体験に関するインタ ビュー結果報告会とコンコーダンス概念の勉強会を通して，看護師の療養指導時の認識や実践にどのよ うな変化がおこるのかを記述し，そのプロセスを考察することである． 方法：2018 年 5 月～2020 年 3 月にアクションリサーチにより腎臓内科病棟看護師に報告会および勉強 受付日：2021 年 4 月 19 日 受理日：2021 年 7 月 10 日
