Factors related to the fatigue of relief workers in areas affected by the Great East Japan Earthquake : survey results 2.5 years after the disaster

Background: After the Great East Japan Earthquake (March 11, 2011), the fatigue of relief workers became a major problem in affected areas. In the present study, we conducted a questionnaire survey 2.5 years post-disaster identifying factors related to the fatigue of relief workers. Methods: This survey was cross-sectional and participants (N = 119) were relief workers living in affected areas. We used a self-administered questionnaire which included participants’ current problems, sources of strong feeling of loss, psychological distress and compassion fatigue. Based on answers (Yes/No) to the fatigue item, we created 2 groups; a Fatigue-group and a Non-fatigue group. We employed bivariate analysis on items with significant differences between the two groups and entered them into a multivariable logistic regression model. Results: Fifty-seven (48%) reported that they were “very tired” and were assigned to the Fatigue group. The total score of the 6-item Kessler Psychological Distress Scale (K6) and each subscale score (burnout, secondary trauma, and compassion satisfaction) of the Professional Quality of Life measure (Pro-QOL) in the Fatigue group were significantly higher than those in the Non-fatigue group. There were significant differences between the two groups for 11 items relating to current problems and sources of strong feelings of loss, and the following items were extracted as factors related to the fatigue of relief workers: loss of trust in others (adjusted OR, 10.03: 95%CI, 2.30–43.79), no confidence to continue work (adjusted OR, 6.27: 95%CI, 1.72–22.83), loss of important person(s) (adjusted OR, 5.58: 95%CI, 2.05–15.19), and sleep disturbance (adjusted OR, 5.14: 95%CI, 1.93–13.67). Conclusion: Many relief workers who reported fatigue had experienced various losses and current problems. Adequate consideration and care systems for local relief workers with fatigue should be given for a long-period after a disaster and it is important for the workers themselves to continue accepting support from others and maintaining self-care habits

The Psychosocial Consequences of the Fukushima Disaster: What Are We Suffering From?

The Fukushima Daiichi Nuclear Power Plant accident caused enormous damage in terms of not only the mental status of affected people, but also the cohesiveness of entire communities in Fukushima Prefecture. Regarding individual mental health, many psychiatric issues became apparent after the accident, including, but not limited to, posttraumatic stress disorder, depression, and alcohol or another type of substance abuse. Widespread rumors and damaged reputations caused anxiety among residents and evacuees, eliciting various disparities such as risk perception factors related to compensation or the effects of radiation exposure. As a result, a decrease in community resilience was observed. Additionally, evacuees were frequently exposed to public stigmas resulting from the negative stories regarding compensation issues or the possible genetic effects of radiation exposure. To address these multidimensional mental health problems, several new and unique care facilities were established after the disaster with the aim of providing active interventions for and improving the current well-being of affected people, including evacuees. While a certain level of effectiveness in the provision of outreach services has been seen, issues such as burnout and exhaustion among health care staff working for different care resources have also been observed. In contrast to natural disasters, nuclear disasters tend to have long-term psychosocial consequences on affected people. Therefore, support care resources that could play important roles, especially in the post-disaster phase in affected areas, should be supported by national and local governments on a long-term basis

Disruption of Child Environments and Its Psychological Consequences After the Fukushima Disaster: a Narrative Review Based on the Ecological Systems Model

Purpose of review: A high prevalence of clinically significant mental health problems was found in children affected by the Fukushima disaster in Japan. We reviewed the literature on child mental health to examine how disasters impacted children in Fukushima. Recent findings: Children's environments, such as family and peer systems, were disrupted by radiation concerns and evacuation. As children struggled with less resources at home and school, they also had to deal with discrimination. Various interventions were implemented, ranging from government financial assistance to several mental health services provided by local care resources to families and children. In addition to organizing such interventions discretely in each microsystem, a collaborative approach involving various intervening entities across multiple levels was deemed necessary for providing comprehensive support to the affected children and their families. To promote the healthy psychological development of children, it is necessary to provide multidimensional support for their families, particularly parents, through multidisciplinary collaboration between professionals involved in child and family care

Cytokine expression in human dermal fibroblasts stimulated with eosinophil cationic protein measured by protein array

[Background] : Eosinophil cationic protein (ECP) was reported previously to be involved in allergic inflammation with cytotoxic activity. On the other hand, recent studies showed that ECP did not induce cell death but inhibited the growth of cancer-derived cells. Our previous study indicated that human ECP enhanced differentiation of rat neonatal cardiomyocytes and stress fiber formation in Balb/c 3T3 mouse fibroblasts, while the effects of human ECP on human fibroblasts are unknown. [Objective] : The present study was performed to determine the effects of human ECP on cytokine expression in human fibroblasts by protein array. [Methods] : The effects of recombinant human ECP (rhECP) on normal human dermal fibroblasts (NHDF) were examined by assaying cell growth. Furthermore, cytokine expression of NHDF stimulated by ECP, which could influence cell growth, was evaluated by protein array. [Results] : ECP was not cytotoxic but enhanced the growth of NHDF. The peak rhECP concentration that enhanced the cell counts by 1.56-fold was 100 ng/mL, which was significantly different from cultures without ECP stimulation (ANOVA/Scheffe’s test, P < 0.05). Array analyses indicated that ciliary neurotrophic factor (CNTF), neutrophilactivating peptide (NAP)-2, and neurotrophin (NT)-3 were significantly upregulated in NHDF stimulated with 100 ng/mL ECP compared to those without stimulation. [Conclusion] : ECP is not cytotoxic but enhances the growth of NHDF. CNTF, NAP-2, and NT-3 were suggested to be involved in enhancing the growth of NHDF. These findings will contribute to determination of the role of ECP in allergic inflammation. (Asian Pac J Allergy Immunol 2013;31:271-6

Parental Recognition of Bullying and Associated Factors Among Children After the Fukushima Nuclear Disaster: A 3-Year Follow-Up Study From the Fukushima Health Management Survey

This study examined parental recognition of bullying victimization and associated factors among evacuated children after the 2011 Fukushima Daiichi Nuclear Power Plant accident, using a 3-year follow-up data (wave 1: January 2012; wave 2: January 2013; wave 3: February 2014). The sample included the caregivers of 2,616 children in the first–sixth grades of elementary school, who lived in one of the 13 municipalities that were the target areas of the Mental Health and Lifestyle Survey, conducted as part of the Fukushima Mental Health Management Survey. Across 3 years, around 80% of caregivers responded “not true,” 15% responded “somewhat true,” and 5% responded “certainly true” in response to a question about bullying victimization of their children. Being male was significantly associated with the parental recognition of bullying victimization at wave 1 and wave 3. At wave 1, experiencing the nuclear plant explosion was significantly associated with parental recognition of bullying victimization. Moreover, age at wave 3 was negatively associated with parental recognition of bullying victimization. Our findings will be helpful for establishing community- and school-based mental health care for children, parents, and teachers

Biohydrogen production from oil palm frond juice and sewage sludge by a metabolically engineered Escherichia coli strain

Biohydrogen is considered a promising and environmentally friendly energy source. Escherichia coli BW25113 hyaB hybC hycA fdoG frdc ldhA aceE has been previously engineered for elevated biohydrogen production from glucose. In this study, we show that this strain can also use biomass from oil palm frond (OPF) juice and sewage sludge as substrates. Substrate improvement was accomplished when hydrogen productivity increased 8-fold after enzymatic treatment of the sludge with a mixture of amylase and cellulase. The OPF juice with sewage sludge provided an optimum carbon/nitrogen ratio since the yield of biohydrogen increased to 1.5 from 1.3 mol H2/mol glucose compared to our previous study. In this study, we also reveal that our engineered strain improved 200-fold biohydrogen productivity from biomass sources compared to the unmodified host. In conclusion, we determined that our engineered strain can use biomass as an alternative substrate for enhanced biohydrogen production
