Purpose: The psychological distress of pediatricians is a major problem in bereavement care. In this study, the primary factor related to distress is clarified and the future directions of bereavement care provided by pediatricians are examined. Method: A questionnaire was mailed to Japanese pediatricians belonging to the High-risk Infant Follow-up Association and the Society of Child Neurology. Doctors who actually experienced bereavement care were divided into high and low distress groups. We conducted a comparison of the variables for the two groups using a logistic regression analysis, and the primary factor related to psychological distress was analyzed by the odds ratio (OR) and 95% confidence intervals. Results: The primary factors related to psychological distress were found to be the following 4 items: "gender," "years of experience," "acquisition of coping method," and "feelings of helplessness." In the high distress group, most pediatricians were women, lacked experience, had no coping methods, and felt helplessness. Conclusion: Countermeasures are required for people feeling strong psychological distress. It is necessary to let pediatricians know that their support is helping the bereaved families and to strive to improve their feelings of helplessness. Education for appropriate coping methods and self-care is required for pediatricians desiring to study bereavement care. Consideration is particularly required for doctors who are female and those who lack experience.

Under osteoconductive conditions, porous calcium phosphate ceramics are known to induce new bone formation within their pores. A critical aspect of the design of porous ceramics is the geometrical features of their pores, with regard to promoting bone formation and mass transfer management in pore networks. However, the pore geometries of common porous ceramics lack clear details. Further, the connections between pores are hard to characterize and thus have not been thoroughly researched. To address these issues, we have developed an original method for fabricating porous ceramics, which we have termed "mosaic-like ceramics fabrication (MLCF)." Using MLCF, pore geometries can be designed and fabricated by each unit, and a network covering all the pores can be fabricated. Furthermore, MLCF can be used to build porous ceramics with custom-made shapes. In this study, we assessed the osteogenic influences of MLCF products (MLPC) composed of hydroxyapatite units on the differentiation of rat bone-marrow-derived mesenchymal stem cells (MSCs) in vitro and in vivo. Two types of commercial porous artificial bone were used as positive controls. MLPC was superior in osteogenic potential, and proved to be a reliable scaffold for bone tissue engineering. Furthermore, this study succeeded in defining the important geometries for osteoconduction. © 2013 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 101A: 3571-3579, 2013.

A field study was conducted to investigate the reduction of plastic bag usage at supermarkets. Many behaviors leading to potential damage to the environment may be unintentional. This study applied a dual motivation model to plastic bag usage and examined the effects of an intervention aimed at promoting pro-environmental behavior. A voice prompt intervention was implemented in Japanese supermarkets. In the first (control) week, shoppers were given free plastic bags by the cashier. In the second (intervention) week, cashiers asked shoppers whether they wanted plastic bags. We collected observational and questionnaire measures of variables that predicted free plastic bag usage during the intervention. The results supported a dual motivation model of behavioral change. The voice prompt decreased the usage of plastic bags by both discouraging unintentional usage and encouraging an intentional reduction in usage. Possibilities for interventions designed both to attenuate unintentional motivation and to promote intentional motivation are considered. © 2014 Elsevier B.V.

Aim: Comparing sleep measures of infants derived from two data collection methods, acceleration sensors and sleep diaries, and identify the clinical application for each data collection method. Methods: The participants were 52 pairs of infants and mothers. Infant sleep measures were obtained through the actigraphs (Micro-mini RC, Ambulatory Monitoring Inc., Ardsley, NY, USA) and sleep diaries for over a period of 7 days. Results: The results showed that the concordance in sleep measures derived from two methods showed decreases in the following order: sleep offset time [r = 0.91 (p = 0.00)], sleep onset time r = 0.89 (p = 0.00), nocturnal sleep duration [r = 0.75 (p = 0.00)], the number of night wakings [r = 0.46 (p < 0.01)] and WASO [r = 0.34 (p < 0.05)]. It was revealed that the accuracy of sleep diary records was affected by the sleeping place and varied throughout the study period. Conclusion: It was confirmed that the sleep measures indicating sleep schedule reported from the sleep diaries had high concordances compared with the data from the actigraphs. Using the sleep diary was recommended to understand behaviours when focusing on infant's daily rhythms. In terms of accuracy and stability of recording throughout the study period, understanding sleep quality and independence of sleeping places, the choice of actigraph was recommended. © 2011 The Author(s)/Acta Pædiatrica.

Background and aims: Reducing health care costs through preventive geriatric care has become a high priority in Japan. We analyzed data from a randomized controlled trial to examine the effects of a preventive home visit program on health care costs among ambulatory frail elders. Methods: Structured preventive home visits by nurses or care managers were provided to the visit group every 6 months over 2 years. The enrolled participants (N = 323) were randomly assigned to either the visit group (N = 161) or the control group (N = 162). We analyzed the health care costs, including the costs for hospitalizations and outpatient clinic utilization for participants who had health care insurance from the local government (N = 307). The visit group included 154 individuals in the visit group and 153 people in the control group. Results: Total health care costs over the study period were not significantly different between groups, but at most monthly time points costs and those for outpatient clinic utilization in the visit group were lower than those in the control group. Hospitalizations, which accounted for more than ¥500,000 JPY per month, were less likely to occur more often among participants in the visit group (N = 71) than in the control group (N = 113) (OR = 0.63; p = 0.002). Conclusions: These results suggest that a preventive home visit program may reduce monthly health care costs, primarily by reducing hospitalization costs. © 2013 The Author(s).
