This study aimed to examine feasibility and to preliminary explore effectiveness of mindfulnessbased cognitive therapy (MBCT) in Japanese breast cancer patients, and to explore possible modification of the program so that it fits better with this population. Methods: Twelve participants with diagnosis of Stage I-III breast cancer received an eight session, weekly MBCT intervention in a group therapy format. The participants were followed up until 3 months after the completion of the program. Results: All the participants completed the program with high attendance rate (mean number of attended sessions = 7.7). Significant improvement in anxiety (Hospital Anxiety and Depression Scale (HADS) - anxiety subscale; effect size Cohen's d = 0.88, P < 0.05), trauma-related psychological symptoms (Impact of Event Scale-revised; d = 0.64, P < 0.01) and quality of life (Functional Assessment of Cancer Therapy-Breast Cancer: FACT-B; d = 0.72, P < 0.01), and trend-level improvement in depression (HADS - depression subscale; d = 0.53, P = 0.054) were observed. Qualitative analyses suggested the program may be beneficial for alleviating fear of cancer recurrence and for increasing spiritual well-being. Some recommended modification of the program was indicated from the post-intervention interviews. Conclusions: Mindfulness-based cognitive therapy was well accepted by Japanese breast cancer patients and yielded favorable effect on their psychological status and quality of life. Further effectiveness study in a randomized-control design is warranted.

Background: Caregivers of people with dementia are likely to have psychological distress that sometimes results in mental health problems, such as depression. The objective of this study was to examine some predictive factors that are thought to be associated with psychological distress of caregivers of people with dementia in Japan. Methods: Design: A cross-sectional study. Sample: As part of a study to estimate the cost of dementia in Japan, 1,437 people with dementia-caregiver dyads were enrolled in the current informal care time study. The measurements in the study included were the basic characteristics of the caregivers and the people with dementia, and the informal care time during a week.Analysis: Factors that predict caregivers' psychological distress, which was measured by Kessler's Psychological Distress scale (K6) score, were evaluated using univariate and multivariate regression analyses. Results: Approximately 69% of the caregivers recorded a K6 score higher than 4, while 18% scored higher than 12. According to the results of the logistic regression analysis (cut-off 4/5), the K6 score was associated with mental and comorbid diseases of people with dementia, informal care time, its lower number of caregivers, and the level of nursing care. According to the results of logistic regression analysis (cut-off 12/13), the K6 score was associated with mental symptoms and comorbid disease of people with dementia, sex of caregivers, informal care time, and its lower number of caregivers. Conclusion: Our findings indicated that the psychological distress of the caregivers is quite high and that informal care time and behavioral and psychological symptoms of dementia are associated with it. These results corroborate with previous findings.

Prescription of psychotropic drugs could be considered to be a proxy for manifestation of psychiatric symptoms. The aim of this study was to investigate the prescriptions of psychotropics in outpatients receiving synthetic glucocorticoids. Methods: We used the claims sampling data during January 2015 from the National Database of Health Insurance Claims and Specific Health Checkups of Japan made by the Ministry of Health, Labor, and Welfare in Japan. We compared the prescription rates of psychotropics between outpatients receiving oral synthetic glucocorticoids and age- and sex-matched controls and the prescription rates of psychotropics among the eight dosage groups of synthetic glucocorticoids by chi-squared test, and chlorpromazine/imipramine/diazepam equivalent doses (or daily defined doses) of respective psychotropics among these groups using Welch's t-test. Results: Synthetic glucocorticoids were prescribed to 3.1% (n = 18 122) of 581 990 patients. The prescription rates of psychotropics were significantly higher among the synthetic glucocorticoid recipients than among the non-recipients: antipsychotics, 1.8% (n = 321) vs. 1.1% (n = 201) (P = 1.4 × 10−7); antidepressants, 4.0% (n = 724) vs. 2.0% (n = 359) (P = 8.7 × 10−30); anxiolytics/hypnotics, 16.7% (n = 3029) vs. 10.2% (n = 1841) (P = 2.7 × 10−75); and mood stabilizers, 1.3% (n = 238) vs. 0.7% (n = 120) (P = 3.6 × 10−10) respectively. There was no significant difference in the prescription rates of any psychotropic drugs, other than anxiolytics/hypnotics, among the eight synthetic glucocorticoid dosage groups. Conclusion: Prescriptions of oral synthetic glucocorticoids were found to be associated with the use of any of the types of psychotropic drugs, other than anxiolytics/hypnotics, although a causal relationship could not be confirmed due to the retrospective and cross-sectional nature of this study.

Objective Dementia has become a global critical issue. It is estimated that the global cost of dementia was 818 billion USD in 2015. The situation in Japan, which is the most aged country in the world, should be critical. However, the societal cost of dementia in Japan has not yet been estimated. This study was designed to estimate cost of dementia from societal perspective. Design We estimated the cost from societal perspective with prevalence based approach. Setting, participants and measures Main data sources for the parameters to estimate the costs are the National Data Base, a nationwide representative individual-level database for healthcare utilization, the Survey of Long-Term Care Benefit Expenditures, a nationwide survey based on individual-level secondary data for formal long-term care utilization, and the results of an informal care time survey for informal care cost. We conducted the analyses with ‘probabilistic modeling’ using the parameters obtained to estimate the costs of dementia. We also projected future costs. Results The societal costs of dementia in Japan in 2014 were estimated at JPY 14.5 trillion (se 66.0 billion). Of these, the costs for healthcare, long-term care, and informal care are JPY 1.91 trillion (se 4.91 billion), JPY 6.44 trillion (se 63.2 billion), and JPY 6.16 trillion (se 12.5 billion) respectively. The cost per person with dementia appeared to be JPY5.95 million (se 27 thousand). The total costs would reach JPY 24.3 trillion by 2060, which is 1.6 times higher than that in 2014. Conclusions The societal cost of dementia in Japan appeared to be considerable. Interventions to mitigate this impact should be considered.
