Efficacy of Zinc Acetate in the Treatment of Zinc Deficiency in Elderly Inpatients and Effect of Total Dose on Its Replacement Therapy.

We aimed to determine the efficacy of zinc acetate hydrate (ZAH) treatment for hypozincemia in elderly inpatients and to identify the factors affecting its therapeutic effect. We enrolled 79 patients with a mean age of 82 years. The mean serum zinc level before ZAH administration was 53.4 ± 11.5 µg/dL. More than half of the patients (67%) had zinc deficiency (<60 µg/dL), whereas 33% had subclinical zinc deficiency (60-80 µg/dL). The median increase in serum zinc level per ZAH tablet (25 mg) was 1.00 µg/dL. Based on the cutoff value, two groups were identified: slight increase (<1.00 µg/dL) and marked increase (≥1.00 µg/dL) groups; the difference between the two groups was significant (0.57 ± 0.22 µg/dL, n = 39 vs. 1.68 ± 0.70 µg /dL, n = 40; p < 0.0001, Wilcoxon rank sum test). Logistic regression analysis using total zinc dose, serum albumin level, impaired renal function, and diuretics as multivariate variables revealed a significant difference in total zinc dose (total number of tablets per 25 mg tablet: odds ratio 1.056, 95% confidence interval 1.019-1.095, p = 0.003). A significant increase in serum zinc levels was observed in the group with a total zinc dose of less than 1000 mg. The results suggest that an increasing trend in total zinc dose is associated with a low increase in serum zinc levels. Therefore, for the treatment of zinc deficiency in elderly inpatients, serum zinc levels need to be measured once, at a total dose of 1000 mg after initiation of ZAH.

[Supervision in Psychiatric Training].

Psychotherapy is an essential component of psychiatric treatment. Although appropriate training including supervision is essential to become able to conduct psychotherapy skillfully, supervision has not been performed in the training of Japanese psychiatrists. In this article, we explain how to utilize supervision in psychiatric training.

Reliability and validity of the Japanese version of the Cognitive Therapy Awareness Scale: a scale to measure competencies in cognitive therapy.

AIM: This study aimed to test reliability and validity of the Japanese-version Cognitive Therapy Awareness Scale, a self-rating scale that measures basic knowledge of cognitive behavioral therapy (CBT) concepts and methodology. Furthermore, we explored optimal cutoff score to demonstrate required standard of CBT competency. METHODS: The reliability and validity of the scale was tested among 252 mental health professionals. The participants' number of readings relevant to CBT, as well as their experience in training and practice in CBT were used as external standards of competency. RESULTS: The scale has good internal consistency (the Kuder-Richardson formula 20=0.76). The total score of the scale was significantly correlated with experience in training and practice in cognitive behavioral therapy, and the number of relevant readings (Spearman's rho =0.27, 0.28 and 0.44, respectively, P<0.001). No significant correlation was found between the total score of the scale and experience in general psychosocial care (Spearman's rho = -0.02, P=0.76). The receiver operating characteristics curve analysis produced the area under curve (AUC) of 0.77 (SD=0.05, P<0.001), and a cutoff score of 31/32 produced sensitivity of 0.81 and specificity of 0.64 to discriminate trainees who have experience of 40 h or more of CBT training and five or more of relevant readings, from those who do not meet this standard. CONCLUSION: The Japanese-version Cognitive Therapy Awareness Scale was successfully validated. It has been demonstrated that the scale specifically assess knowledge in cognitive behavioral therapy. This scale would serve as a rough guide to assess competencies among beginner cognitive behavior therapists.

Cost of depression among adults in Japan in 2005.

AIM: Major depression is expected to become the leading contributor to disease burden worldwide by 2020. Previous studies have shown that the societal cost of depression is not less than that of other major illnesses, such as cardiovascular diseases or AIDS. Nevertheless, the cost of depression in Japan has never been examined. The goal of the present study was to estimate the total cost of depression in Japan and to clarify the characteristics of this burden. METHODS: A prevalence-based approach was adopted to measure the total cost of depression. The total cost of depression was regarded as being comprised of the direct cost, morbidity cost and mortality cost. Diagnoses included in this study were depressive episodes and recurrent depressive disorder according to the ICD-10 or major depressive disorder according to the DSM-IV. Data were collected from publicly available statistics and the World Mental Health Japan Survey database. RESULTS: The total cost of depression among adults in Japan in 2005 was estimated to be ¥2.0 trillion. The direct cost was ¥0.18 trillion. The morbidity cost was ¥0.92 trillion, while the mortality cost was ¥0.88 trillion. CONCLUSION: The societal costs caused by depression in Japan are enormous, as in other developed countries. Low morbidity costs and extremely high mortality costs are characteristic in Japan. Effective interventions for preventing suicide could reduce the societal costs of depression.

[Effect of Storage of Tulobuterol Tapes after Package Opening and Liner Peeling on Their Formulation Properties].

Although tulobuterol tape is provided to patients in an inner package, information regarding the stability of the tape after opening the packaging may be requested by patients. This study was performed to generate underlying data on the storage stability after package opening or liner peeling with package opening. Tulobuterol tapes were stored at 25℃, 60% relative humidity (RH); 40℃, 75%RH; or in a refrigerator (2-4℃, 10-30%RH) for 1 day or 3 days. In a peel adhesive strength test after package opening, storage at 25℃, 60%RH had a low effect on the adhesive strength of the tape. Storage after liner peeling with package opening resulted in variable adhesive strength of the tape. Regarding drug release properties, for storage after package opening, the f2 values of tapes stored in the three different conditions were over 50, except for tapes stored at 25℃, 60%RH for 3 days. For the tapes stored at 25℃, 60%RH or 40℃, 75%RH after liner peeling with package opening, the release rate and the ratio of drug released at 24 h may be decreased because the drug content decreased due to drug sublimation. This study suggested that tulobuterol tapes can be stored after package opening at 25℃, 60%RH for 1 d.

The effect of an educational leaflet on depressive patients' attitudes toward treatment.

Improving patient adherence to antidepressant treatment is an important issue. Patients' attitudes toward symptoms, results, causes, disease course, and effective treatment of depression can influence their adherence to therapy. We aimed to assess the efficacy of an educational leaflet designed to improve patients' attitudes toward depression and antidepressant treatment. Participants were one hundred twenty-two outpatients of three psychiatric clinics in Japan who met the DSM-IV criteria for depression. Patients in the intervention group received an educational leaflet at the start of the study. Participants filled in The Antidepressant Compliance Questionnaire (ADCQ) and Beck Depression Inventory (BDI) before and after the intervention. Intervention group showed greater improvements on the total score of ADCQ, the score on the "positive beliefs regarding antidepressants" subscale. They maintained the scores on the "perceived doctor-patient relationship" subscale, where the control group lowered those scores. No significant difference in improvement in BDI scores was observed between groups. The intervention using an educational leaflet had a significant positive impact on patients' attitudes toward depression and antidepressant treatment. Our results indicate that the educational leaflet is an effective tool for enhancement of face-to-face education by medical professionals.

A community intervention trial of multimodal suicide prevention program in Japan: a novel multimodal community intervention program to prevent suicide and suicide attempt in Japan, NOCOMIT-J.

BACKGROUND: To respond to the rapid surge in the incidence of suicide in Japan, which appears to be an ongoing trend, the Japanese Multimodal Intervention Trials for Suicide Prevention (J-MISP) have launched a multimodal community-based suicide prevention program, NOCOMIT-J. The primary aim of this study is to examine whether NOCOMIT-J is effective in reducing suicidal behavior in the community. METHODS/DESIGN: This study is a community intervention trial involving seven intervention regions with accompanying control regions, all with populations of statistically sufficient size. The program focuses on building social support networks in the public health system for suicide prevention and mental health promotion, intending to reinforce human relationships in the community. The intervention program components includes a primary prevention measures of awareness campaign for the public and key personnel, secondary prevention measures for screening of, and assisting, high-risk individuals, after-care for individuals bereaved by suicide, and other measures. The intervention started in July 2006, and will continue for 3.5 years. Participants are Japanese and foreign residents living in the intervention and control regions (a total of population of 2,120,000 individuals). DISCUSSION: The present study is designed to evaluate the effectiveness of the community-based suicide prevention program in the seven participating areas. TRIAL REGISTRATION: UMIN Clinical Trials Registry (UMIN-CTR) UMIN000000460.

Prevalence of and risk factors for suicide-related outcomes in the World Health Organization World Mental Health Surveys Japan.

AIM: Suicide is a major public health concern in Japan but little is known about the prevalence of and risk factors for suicidal ideation, plans, and attempts. The aim of the present study was to clarify the prevalence of and risk factors for important suicide-related outcomes. METHODS: Important suicide-related outcomes and risk factors were assessed in face-to-face interviews with 2436 adult respondents in seven areas as part of the World Health Organization (WHO) World Mental Health Survey Initiative. Mental disorders were assessed with the WHO Composite International Diagnostic Interview (CIDI). RESULTS: The lifetime prevalence estimates of suicidal ideation, plans, and attempts were 10.9%, 2.1%, and 1.9%, respectively. Risk of suicide plans and attempts was highest when suicidal ideation occurred at an early age and within the first year of ideation. In middle-aged individuals, the period after first employment and the presence of mental disorders were risk factors. CONCLUSIONS: Risk of suicide plans and attempts is highest when suicidal ideation occurred at an earlier age and within the first year of ideation. Mental disorders are as predictive of the suicide-related outcomes examined here, and comorbidity is an important predictor.

Effect of a brief training program based on cognitive behavioral therapy in improving work performance: A randomized controlled trial.

OBJECTIVES: Efforts to improve performance in the workplace with respect to positive mental health have increased, and cognitive behavioral therapy (CBT) has recently attracted attention as an intervention measure to this end. Here, we conducted a randomized controlled trial to evaluate the effectiveness of a brief training program on CBT for improving work performance of employees. METHODS: The participants were employees of an electric company in Japan. The intervention consisted of 1 group session of CBT (120 min) and web-based CBT homework for 1 month. We evaluated employees in both the intervention and control groups at baseline and follow-up after three months. The main outcome was work performance, which was evaluated by a subjective score from 1 to 10. The secondary outcome was self-evaluation of cognitive flexibility. Analyses were conducted based on ITT. RESULTS: In the intervention group, 84 participants attended the group session, with 79 subsequently completing at least 1 instance of online homework. ITT analysis showed that the subjective performance of the intervention group was significantly improved compared with that of the control group (1.47 vs. 0.69, mean difference 0.78 [95% confidence interval {CI}, 0.05 to 1.51], Cohen's d=0.31). The ability to recognize dysfunctional thinking patterns and change them to positive ones significantly improved in the intervention group compared to the control group (0.71 vs. 0.26, mean difference 0.45 [95% CI 0.06 to 0.83], d=0.33). However, after adjustment for baseline scores, no significant difference was observed. The ability to view a situation from multiple perspectives and expand one's repertoire of thought patterns in the intervention group also significantly improved (0.83 vs. 0.35, mean difference 0.48 [95% CI 0.35 to 0.95], d=0.29), but here again, significance was lost after adjusting for baseline scores. DISCUSSION: Our results suggest that a brief training program that combines a group CBT session with web-based CBT homework improved subjective work performance. In addition, this program might help improve employees' cognitive flexibility.

A web-based training program using cognitive behavioral therapy to alleviate psychological distress among employees: randomized controlled pilot trial.

BACKGROUND: A number of psychoeducational programs based on cognitive behavioral therapy (CBT) to alleviate psychological distress have been developed for implementation in clinical settings. However, while these programs are considered critical components of stress management education in a workplace setting, they are required to be brief and simple to implement, which can hinder development. OBJECTIVE: The intent of the study was to examine the effects of a brief training program based on CBT in alleviating psychological distress among employees and facilitating self-evaluation of stress management skills, including improving the ability to recognize dysfunctional thinking patterns, transform dysfunctional thoughts to functional ones, cope with stress, and solve problems. METHODS: Of the 187 employees at an information technology company in Tokyo, Japan, 168 consented to participate in our non-blinded randomized controlled study. The training group received CBT group education by a qualified CBT expert and 1 month of follow-up Web-based CBT homework. The effects of this educational program on the psychological distress and stress management skills of employees were examined immediately after completion of training and then again after 6 months. RESULTS: Although the training group did exhibit lower mean scores on the Kessler-6 (K6) scale for psychological distress after 6 months, the difference from the control group was not significant. However, the ability of training group participants to recognize dysfunctional thinking was significantly improved both immediately after training completion and after 6 months. While the ability of participants to cope with stress was not significantly improved immediately after training, improvement was noted after 6 months in the training group. No notable improvements were observed in the ability of participants to transform thoughts from dysfunctional to functional or in problem-solving skills. A sub-analysis of participants who initially exhibited clinically significant psychological distress (K6 score ≥5) showed that the mean K6 score was significantly improved immediately after training completion for the training group compared to the control group (-2.50 vs -0.07; mean difference 2.43, 95% CI 0.55-4.31; d=0.61), with this effect remaining even after 6 months (-3.49 vs -0.50; mean difference 2.99, 95% CI 0.70-5.29; d=0.60). CONCLUSIONS: Our results suggest that a brief stress management program that combines group CBT education with Web-based CBT homework moderately alleviates the distress of employees with clinically significant psychological distress. In addition, the program might help improve employees' ability to evaluate their own stress management skills.

Effectiveness of a multimodal community intervention program to prevent suicide and suicide attempts: a quasi-experimental study.

BACKGROUND: Multilevel and multimodal interventions have been suggested for suicide prevention. However, few studies have reported the outcomes of such interventions for suicidal behaviours. METHODS: We examined the effectiveness of a community-based multimodal intervention for suicide prevention in rural areas with high suicide rates, compared with a parallel prevention-as-usual control group, covering a total of 631,133 persons. The effectiveness was also examined in highly populated areas near metropolitan cities (1,319,972 persons). The intervention started in July 2006, and continued for 3.5 years. The primary outcome was the incidence of composite outcome, consisting of completed suicides and suicide attempts requiring admission to an emergency ward for critical care. We compared the rate ratios (RRs) of the outcomes adjusted by sex, age group, region, period and interaction terms. Analyses were performed on an intention-to-treat basis and stratified by sex and age groups. FINDINGS: In the rural areas, the overall median adherence of the intervention was significantly higher. The RR of the composite outcome in the intervention group decreased 7% compared with that of the control group. Subgroup analyses demonstrated heterogeneous effects among subpopulations: the RR of the composite outcome in the intervention group was significantly lower in males (RR = 0.77, 95% CI 0.59-0.998, p = 0.0485) and the RR of suicide attempts was significantly lower in males (RR = 0.39, 95% CI 0.22-0.68, p = 0.001) and the elderly (RR = 0.35, 95% CI 0.17-0.71, p = 0.004). The intervention had no effect on the RR of the composite outcome in the highly populated areas. INTERPRETATION: Our findings suggest that this community-based multimodal intervention for suicide prevention could be implemented in rural areas, but not in highly populated areas. The effectiveness of the intervention was shown for males and for the elderly in rural areas. TRIAL REGISTRATION: ClinicalTrials.gov NCT00737165 UMIN Clinical Trials Registry UMIN000000460.

Cognitive behavioral therapy for depression among adults in Japanese clinical settings: a single-group study.

BACKGROUND: Empirical support for cognitive behavioral therapy (CBT) for treating Japanese patients with major depression is lacking, therefore, a feasibility study of CBT for depression in Japanese clinical settings is urgently required. FINDINGS: A culturally adapted, 16-week manualized individual CBT program for Japanese patients with major depressive disorder was developed. A total of 27 patients with major depression were enrolled in a single-group study with the purpose of testing the feasibility of the program. Twenty six patients (96%) completed the study. The mean total score on the Beck Depression Inventory-II (BDI-II) for all patients (Intention-to-treat sample) improved from 32.6 to 11.7, with a mean change of 20.8 (95% confidence interval: 17.0 to 24.8). Within-group effect size at the endpoint assessment was 2.64 (Cohen's d). Twenty-one patients (77.7%) showed treatment response and 17 patients (63.0%) achieved remission at the end of the program. Significant improvement was observed in measurement of subjective and objective depression severity (assessed by BDI-II, Quick Inventory of Depressive Symptomatology-Self Rated, and Hamilton Depression Rating Scale), dysfunctional attitude (assessed by Dysfunctional Attitude Scale), global functioning (assessed by Global Assessment of Functioning of DSM-IV) and subjective well-being (assessed by WHO Subjective Well-being Inventory) (all p values < 0.001). CONCLUSIONS: Our manualized treatment comprised of a 16-week individual CBT program for major depression appears feasible and may achieve favorable treatment outcomes among Japanese patients with major depression. Further research involving a larger sample in a randomized, controlled trial design is warranted. TRIAL REGISTRATION: UMIN-CTR UMIN000002542.

Efficacy of cognitive behavioral therapy training using brief e-mail sessions in the workplace: a controlled clinical trial.

In the present study, we conducted a clinical controlled trial to evaluate the effects of cognitive behavioral therapy (CBT) training in improving depression and self-esteem in workers. A total of 261 workers were assigned to either an intervention group (n=137) or a waiting-list group (n=124). The intervention group was offered participation in a group session with CBT specialists and three e-mail sessions with occupational health care staff. Between-group differences in the change in Center for Epidemiologic Studies Depression Scale (CES-D) and Self-Esteem Scale from baseline to three months after the end of training were assessed by analysis of covariance. All subjects in the intervention group completed the group session and 114 (83%) completed the three e-mail sessions. CES-D score decreased by 2.21 points in the intervention group but increased by 0.12 points in the control group, a significant difference of -2.33 points (95% confidence interval: -3.89 to-0.77; p<0.001). The between-group difference in change of self-esteem scores was not significant. Results of the present study suggest that CBT training cooperatively provided by CBT specialists and occupational health care staff using brief e-mail is effective in improving feelings of depression in workers.

Reliability and validity of the Japanese version of the 24-item Dysfunctional Attitude Scale.

BACKGROUND: The 24-item Dysfunctional Attitude Scale (DAS-24) is a short version of the Dysfunctional Attitude Scale, which is a self-report inventory for depressogenic schemata. OBJECTIVE: The object of this study was to examine the reliability and validity of the Japanese version of the DAS-24 (DAS-24-J). METHODS: Subjects consisted of non-clinical sample 1 (248 university students), non-clinical sample 2 (872 Japanese company employees) and a clinical sample (59 depressed out-patients). RESULTS: Internal consistency was satisfactory in all three samples, Cronbach's α coefficient being higher than 0.85. Test-retest reliability was satisfactory in non-clinical sample 1. The interclass correlation coefficient was 0.79 and there was no significant difference in the average score of DAS-24-J between the two points. The DAS-24-J showed satisfactory concurrent validity with the Japanese Irrational Belief Test-20 (r= 0.76); Automatic Thoughts Questionnaire - Revised total (r= 0.46), negative (r= 0.53) and positive (r=-0.41); and the Beck Depression Inventory-II (r= 0.44 for non-clinical sample, r= 0.63 for clinical sample). The clinical sample showed a significantly higher DAS-24-J score than non-clinical sample 2. According to a factor analysis combining all three samples, three factors were extracted: factor 1 (11 items) corresponded with 'achievement' in the original version, factor 2 (6 items) with 'self-control' and factor 3 (5 items) with 'dependency'. CONCLUSION: The DAS-24-J is a reliable and valid instrument to measure depressogenic schemata in Japanese.
