RESUMO
OBJECTIVES: we investigated the prevalence and associated factors of depression and complicated grief (CG) among bereaved family members of malignant pleural mesothelioma (MPM) patients in Japan. METHODS: Bereaved family members of MPM patients (n = 72) were surveyed. The Japanese version of the Patient Health Questionnaire-9 (PHQ-9) and the Japanese version of the Brief Grief Questionnaire (BGQ) were used to assess depression and complicated grief (CG), respectively. Socio-economic factors, anger toward asbestos, care satisfaction, achievement of good death, and quality of end-of-life care were assessed in relation to depression and CG. RESULTS: In the family members of MPM patients, the frequencies of depression and CG were 19.4% and 15.3%, respectively. The bereaved family members who were not compensated by the asbestos-related health-damage relief system (p = 0.018) and who felt the financial impacts of the patient's MPM on the family (p = 0.006) had a higher likelihood of depression. The bereaved family members who were not satisfied with the care given when the patient became critical (p = 0.034), who were not compensated by the asbestos-related health-damage relief system (p = 0.020), who felt the financial impact of the patient's MPM on the family (p = 0.016), and whose deceased relative underwent surgery (p = 0.030) had a higher likelihood of CG. CONCLUSIONS: For bereaved family members of MPM patients, routine screening for depression and CG and the provision of grief care are suggested. In addition, for family members of MPM patients, financial support, including the promotion of the asbestos-related health-damage relief system, and improved care for patients who undergo surgery and when patients become critical, are recommended.
RESUMO
OBJECTIVE: This study investigated whether malignant pleural mesothelioma (MPM) patients achieved good deaths and good quality of end-of-life care compared with other cancer patients from the perspective of bereaved family members in Japan. METHODS: This cross-sectional study was part of a larger study on the achievement of good deaths of MPM patients and the bereavement of their family members. Bereaved family members of MPM patients in Japan (n = 72) were surveyed. The Good Death Inventory (GDI) was used to assess the achievement of good death. The short version of the Care Evaluation Scale (CES) version 2 was used to assess the quality of end-of-life care. The GDI and CES scores of MPM patients were compared with those of a Japanese cancer population from a previous study. RESULTS: MPM patients failed to achieve good deaths. Only 12.5% of the MPM patients were free from physical pain. The GDI scores of most of the MPM patients were significantly lower than those of the Japanese cancer population. The CES scores indicated a significantly poorer quality of end-of-life care for the MPM patients than the Japanese cancer population. The total GDI and CES scores were correlated (r = 0.55). CONCLUSIONS: The quality of end-of-life care for MPM patients remains poor. Moreover, MPM patients do not achieve good deaths from the perspective of their bereaved family members.
RESUMO
PURPOSE: To evaluate the long-term health effects of occupational asbestos exposure, an updated historical cohort mortality study of workers at a refitting shipyard was undertaken. METHODS: The cohort consisted of 249 male ship repair workers (90 laggers, 159 boiler repairers). To determine relative excess mortality, standardized mortality ratios (SMRs) were calculated using mortality rates among the Japanese male population. Mortality follow-up of study subjects was performed for the period from 1947 till the end of 2007. RESULTS: We identified the vital status of 87 (96.7%) laggers and 150 (94.3%) boiler repairers. Of these, 63 (72.4%) and 95 (63.3%), respectively, died. Laggers, who had handled asbestos materials directly, showed a significantly elevated SMR of 2.64 (95% confidence interval [CI]: 1.06-5.44) for lung cancer and 2.49 (95% CI: 1.36-4.18) for nonmalignant respiratory diseases. Boiler repairers, who had many opportunities for secondary exposure to asbestos and a few for direct exposure, showed no significant elevation in SMR for lung cancer but a significantly elevated SMR of 1.78 (95% CI: 1.06-2.81) for nonmalignant respiratory diseases. In an analysis according to duration of employment, there was a significantly elevated SMR of nonmalignant respiratory diseases in the longer working years group. Among workers from both jobs, no deaths caused by mesothelioma in addition to those in the original study were found and no subject died from larynx cancer. CONCLUSION: This updated study confirmed a significant excess of asbestos-related mortality from diseases such as lung cancer and nonmalignant respiratory diseases among workers in a refitting shipyard in Japan.

BACKGROUND: Because mesothelioma initially progresses on the surface of the pleura and peritoneum without forming masses, it has been difficult to diagnose at an early stage. It would be very useful to identify a tumor marker that could be used for screening to enable more diagnoses to be made at an early, treatable stage. MATERIALS AND METHODS: We had previously identified N-ERC/mesothelin as a potential biomarker for mesothelioma. In the current work, we used a newly developed ELISA system to gain data on N-ERC/mesothelin levels in various clinical settings. A total of 102 healthy volunteers were recruited. In addition, 39 patients were diagnosed with mesothelioma, 53 patients were diagnosed with diseases that should be distinguished from mesothelioma, and 201 subjects were diagnosed with asbestos-related nonmalignant diseases (including simple exposure to asbestosis) who were treated at any of the cooperating hospitals were enrolled. RESULTS: Serum N-ERC/mesothelin levels measured by a new ELISA system showed that the median values from patients with mesothelioma were extremely high compared with levels obtained from other patients. Analysis in terms of histologic type showed that serum levels of N-ERC/mesothelin were elevated in epithelioid type mesothelioma, especially. In four important models of clinical settings, the sensitivity and specificity of N-ERC/mesothelin were about 71% to 90% and 88% to 93%, respectively. CONCLUSION: N-ERC/mesothelin is a very promising tumor marker for mesothelioma, especially epithelioid mesothelioma.

OBJECTIVE: Occupational Lung Disease is an oldest but still a biggest problem in occupational health. METHODS: Steering Committee members of the Japan Society for Occupational Health (JSOH) Occupational Lung Disease Study Group selected and summarized current topics on occupational lung diseases based on expert opinion, as informed by governmental regulation, public health concerns, and frequently discussed in related academic conferences. RESULTS: The topics included in this review are professional education in medical screening skills, 2014 update of Helsinki Criteria, respiratory diseases found in the earthquake and tsunami affected regions, newly recognized occupational lung diseases, and potential respiratory health hazards. DISCUSSIONS: Although occupational lung diseases seem to stay as one of the major concerns in occupational health, screening tools and control measures are standardized for the better prevention of the diseases. As this health problem usually occurs in where the most actively economically developing area is, the patients tend to increase in emerging economic powers with huge population.

Coexistence of pulmonary adenocarcinoma and pleural malignant mesothelioma is extremely rare, although both are asbestos-related. Herein is presented a rare case of coalescent lung tumor made up of a malignant mesothelioma and a pulmonary adenocarcinoma in a 62-year-old Japanese man, a high-school teacher with only minor asbestos exposure. Preoperative diagnosis of adenocarcinoma was made on transbronchial biopsy. At surgery, multiple small white nodules were observed on the parietal pleural surface, opposite to the lung tumor. They were confirmed to be malignant mesothelioma on histopathology of paraffin section. The pulmonary tumor mass itself consisted of two distinct portions. The major part contained papillary proliferation of hobnail and columnar cells. Peripherally, neoplastic cells grew in a lepidic fashion and micropapillary growth was also detected. The other component featured tubular structures. The former was positive for adenocarcinoma markers such as CEA, Ber-EP4, PE-10, thyroid transcription factor-1 and Napsin A, and negative for mesothelial markers including calretinin, D2-40, WT-1 and HBME, while the latter was the opposite, resulting in a diagnosis of coalescing malignant mesothelioma and adenocarcinoma. The panel of antibodies used for immunohistochemistry was useful to distinguish the two different components in the one tumor.

In 2002 a total ban on asbestos was announced in Japan, following many years of sporadic and variably effective measures intended to control its use in that country. A major factor in instigating the ban was public awareness raised by the publicizing of the experience of asbestos-exposed workers in the U.S. naval base and shipyards at Yokosuka, an inordinate number of whom died of asbestos-related disease. Statistics of asbestos-related disease mortality in Japan are presented. Groups prominent in the effort to establish the ban and make it effective include the Japan Occupational Safety and Health Resource Center (JOSHRC) and the Ban Asbestos Network Japan (BANJAN). Activities of these groups are described.

PURPOSE: In Japan nursing care lags behind the growing population of patients with malignant pleural mesothelioma. This study evaluated an educational program for nurses about caring for patients with malignant pleural mesothelioma in Japan. METHOD: In this randomized controlled study relative to care for malignant pleural mesothelioma, Knowledge, Difficulties and Attitude were measured at baseline, at post-test and at follow-up one month later. The two-day program with a half-day follow-up program included lectures, group work, role-playing and group discussion. 188 participants were randomly assigned to the intervention group (program, n=96) and control group (n=92; self-study by a similar content handbook). At baseline the groups showed no statistical differences in Knowledge (p=0.921), Difficulty (p=0.458) and Attitude (p=0.922). Completing the study were 177 participants yielding 88 in the intervention group and 89 in the control group. Human rights and privacy of participants were protected. RESULTS: The Knowledge score was significantly higher in the intervention post-test (t=14.03, p=0.000) and follow-up test (t=8.98, p=0.000). Difficulty score was significantly lower in the intervention at post-test (t=-3.41, p=0.001) and follow-up test (t=-3.70, p=0.000). The Attitude score was significantly higher in the intervention post-test (t=7.11, p=0.000) and follow-up test (t=4.54, p=0.000). The two-way analysis of variance with repeated measures on time showed an interaction between time and group; the subsequent simple main effect test found significant differences (p=0.000-0.001) between groups for after-program and at follow-up and a significant difference (p=0.000) in time only within the intervention group. CONCLUSION: The educational program was effective in improving the nurses' knowledge and attitude toward malignant pleural mesothelioma care and decreasing the difficulty in MPM care, therefore this program has potential for nurses' in-service education throughout Japan.

PURPOSE: This study evaluated the effect of an Educational PROGRAM on Palliative Care for MPM for Nurses in Japan. PROGRAM: The 5-h program consisted of lectures and care planning group work. MATERIALS AND METHODS: This study used a pretest-posttest design with a single cohort of nurses and included a Difficulties in Palliative Care for Patients with MPM (DPCMPM) Scale with 15 items. The pre- and posttest scores were compared using a t-test. RESULTS: We included 27 female nurses with a mean of 14.4 years of nursing experience. In 12 of 15 DPCMPM items, the posttest difficulty scores were lower than the pretest scores. Participants highly evaluated the program for validity, clarity, clinical usefulness, and the facilitators. The Palliative Care for MPM Handbook for Nurses was developed as an educational tool for clinical settings. CONCLUSIONS: The Educational PROGRAM on Palliative Care for MPM for Nurses was effective in reducing nursing difficulties.

BACKGROUND: Japanese consumption of asbestos increased rapidly after the 1950s and lingered at a high level while the world's consumption decreased substantially after the 1980s. Mesothelioma is due primarily to asbestos, and the number of deaths in Japan is expected to increase in the future. METHOD: We estimated the future number of pleural mesothelioma deaths among males in Japan using an age-cohort model. RESULTS: Analyses showed that there would be about 100,000 deaths in Japan due to pleural mesothelioma in the next 40 years. Compared with the statistics in European countries, the ratio of expected death numbers to the population size is remarkably close to linear. The data-point for Japan was slightly lower than that which could be expected from the linear relationship. CONCLUSIONS: The limited availability of data may result in underestimation. Taking into consideration the consumption pattern of asbestos in recent decades, the incorporation of later cohorts will improve the estimation.
