Abstract
Background A major problem in providing mental health services is the lack of access to treatment, especially in remote areas. Thus far, no clinical studies have demonstrated the feasibility of internet-based cognitive behavioral therapy (ICBT) with real-time therapist support via videoconference for bulimia nervosa and binge-eating disorder in Japan. Objective The goal of the research was to evaluate the feasibility of ICBT via videoconference for patients with bulimia nervosa or binge-eating disorder. Methods Seven Japanese subjects (mean age 31.9 [SD 7.9] years) with bulimia nervosa and binge-eating disorder received 16 weekly sessions of individualized ICBT via videoconference with real-time therapist support. Treatment included CBT tailored specifically to the presenting diagnosis. The primary outcome was a reduction in the Eating Disorder Examination Edition 16.0D (EDE 16D) for bulimia nervosa and binge-eating disorder: the combined objective binge and purging episodes, objective binge episodes, and purging episodes. The secondary outcomes were the Eating Disorders Examination Questionnaire, Bulimic Investigatory Test, Edinburgh, body mass index for eating symptoms, Motivational Ruler for motivation to change, EuroQol-5 Dimension for quality of life, 9-item Patient Health Questionnaire for depression, 7-item Generalized Anxiety Disorder scale for anxiety, and Working Alliance Inventory–Short Form (WAI-SF). All outcomes were assessed at week 1 (baseline) and weeks 8 (midintervention) and 16 (postintervention) during therapy. Patients were asked about adverse events at each session. For the primary analysis, treatment-related changes were assessed by comparing participant scores and 95% confidence intervals using the paired t test. Results Although the mean combined objective binge and purging episodes improved from 47.60 to 13.60 (71% reduction) and showed a medium effect size (Cohen d=–0.76), there was no significant reduction in the combined episodes (EDE 16D –41; 95% CI –2.089 to 0.576; P=.17). There were no significant treatment-related changes in secondary outcomes. The WAI-SF scores remained consistently high (64.8 to 66.0) during treatment. Conclusions ICBT via videoconference is feasible in Japanese patients with bulimia nervosa and binge-eating disorder.

Abstract
Objective Guided self-help treatments based on cognitive behavioral therapy (CBT-GSH) are regarded as a first-line effective treatment for bulimia nervosa (BN). With limited application for CBT-GSH in Japanese clinical settings, we conducted a single arm pilot study in order to confirm the acceptability and availability of CBT-GSH in Japan. Results 25 women with BN received 16–20 sessions of face-to-face CBT-GSH. Primary outcomes were the completion rate of intervention and abstinence rates from objective bingeing and purging as assessed by the Eating Disorder Examination. Secondary outcomes were other self-report measurements of the frequency of bingeing and purging, and characteristic psychopathologies of eating disorders. Assessments were conducted before CBT as baseline as well as after CBT. 92% (23/25) of the participants completed the CBT sessions. After CBT-GSH, 40% (10/25) of the participants (intention-to-treat) achieved symptom abstinence. The mean binge and purge episodes during the previous 28 days improved from 21.88 to 10.96 (50% reduction) and from 22.44 to 10.88 (52% reduction), each (before CBT-GSH to after CBT-GSH), and the within-group effect sizes were medium (Cohen’s d = 0.67, 0.65, each). Our study provided a preliminary evidence about the feasibility of CBT-GSH in Japanese clinical settings for the future.

Abstract
Objective Mental defeat and cognitive flexibility have been studied as explanatory factors for depression and posttraumatic stress disorder. This study examined mental defeat and cognitive flexibility scores in patients with panic disorder (PD) before and after cognitive behavioral therapy (CBT), and compared them to those of a gender- and age-matched healthy control group. Results Patients with PD (n = 15) received 16 weekly individual CBT sessions, and the control group (n = 35) received no treatment. Patients completed the Mental Defeat Scale and the Cognitive Flexibility Scale before the intervention, following eight CBT sessions, and following 16 CBT sessions, while the control group did so only prior to receiving CBT (baseline). The patients’ pre-CBT Mental Defeat and Cognitive Flexibility Scale scores were significantly higher on the Mental Defeat Scale and lower on the Cognitive Flexibility Scale than those of the control group participants were. In addition, the average Mental Defeat Scale scores of the patients decreased significantly, from 22.2 to 12.4, while their average Cognitive Flexibility Scale scores increased significantly, from 42.8 to 49.5. These results suggest that CBT can reduce mental defeat and increase cognitive flexibility in patients with PD Trial registration The study was registered retrospectively in the national UMIN Clinical Trials Registry on June 10, 2016 (registration ID: UMIN000022693).

Abstract
BACKGROUND Although antidepressants are still a commonly used treatment for social anxiety disorder (SAD), a significant proportion of patients fail to remit following antidepressants. However, no standard approach has been established for managing such patients. This study aimed to examine the effectiveness of cognitive behavioral therapy (CBT) as an adjunct to usual care (UC) compared with UC alone in SAD patients who remain symptomatic following antidepressant treatment. METHODS This was a prospective randomized open-blinded end-point study with two parallel groups (CBT + UC, and UC alone, both for 16 weeks) conducted from June 2012 to March 2014. SAD patients who remain symptomatic following antidepressant treatment were recruited, and a total sample size of 42 was set based on pilot results. RESULTS Patients were randomly allocated to CBT + UC (n = 21) or UC alone (n = 21). After 16 weeks, adjusted mean reduction in the Liebowitz Social Anxiety Scale from baseline for CBT + UC and UC alone was -40.87 and 0.68, respectively; the between-group difference was -41.55 (-53.68 to -29.42, p < 0.0001). Response rates were 85.7 and 10.0% for CBT + UC and UC alone, respectively (p < 0.0001). The corresponding remission rates were 47.6 and 0.0%, respectively (p = 0.0005). Significant differences were also found in favor of CBT + UC for social anxiety symptoms, depressive symptoms, and functional impairment. CONCLUSIONS Our results suggest that in SAD patients who have been ineffectively treated with antidepressants, CBT is an effective treatment adjunct to UC over 16 weeks in reducing social anxiety and related symptoms.

Abstract
Background In Japan, cognitive behavioral therapy (CBT) for panic disorder (PD) is not well established. Therefore, a feasibility study of the clinical effectiveness and cost-effectiveness of CBT for PD in a Japanese clinical setting is urgently required. This was a pilot uncontrolled trial and the intervention consisted of a 16-week CBT program. The primary outcome was Panic Disorder Severity Scale (PDSS) scores. Quality of life was assessed using the EuroQol’s EQ-5D questionnaire. Assessments were conducted at baseline, 8 weeks, and at the end of the study. Fifteen subjects completed outcome measures at all assessment points. Results At post-CBT, the mean reduction in PDSS scores from baseline was −6.6 (95 % CI 3.80 to −9.40, p < 0.001) with a Cohen’s d = 1.77 (95 % CI 0.88–2.55). Ten (66.7 %) participants achieved a 40 % or greater reduction in PDSS. By calculating areas under the curve for EQ-5D index changes, we estimated that patients gained a minimum of 0.102 QALYs per 1 year due to the CBT. Conclusions This study demonstrated that individual CBT for PD may be useful in Japanese clinical settings but further randomized control trials are needed.

Abstract
BACKGROUND Cognitive behavior therapy (CBT) is regarded as an effective treatment for social anxiety disorder (SAD) in Europe and North America. Individual CBT might be acceptable and effective for patients with SAD even in non-Western cultures; therefore, we conducted a feasibility study of individual CBT for SAD in Japanese clinical settings. We also examined the baseline predictors of outcomes associated with receiving CBT. METHODS This single-arm trial employed a 14-week individual CBT intervention. The primary outcome was the self-rated Liebowitz Social Anxiety Scale, with secondary measurements of other social anxiety and depressive severity. Assessments were conducted at baseline, after a waiting period before CBT, during CBT, and after CBT. RESULTS Of the 19 subjects screened, 15 were eligible for the study and completed the outcome measures at all assessment points. Receiving CBT led to significant improvements in primary and secondary SAD severity (ps < .001). The mean total score on the Liebowitz Social Anxiety Scale improved from 91.8 to 51.7 (before CBT to after CBT), and the within-group effect size at the end-point assessment was large (Cohen's d = 1.71). After CBT, 73% of participants were judged to be treatment responders, and 40% met the criteria for remission. We found no significant baseline predictors of those outcomes. CONCLUSION Despite several limitations, our treatment-which comprises a 14-week, individual CBT program-seems feasible and may achieve favorable treatment outcomes for SAD in Japanese clinical settings. Further controlled trials are required in order to address the limitations of this study. TRIAL REGISTRATION UMIN-CTR UMIN000005897.

Abstract
In order to confirm the structure of three fecal metabolites, M-I, M-II and M-III, of a new calcium antagonist, (+)-3,4-dihydro-2-[5-methoxy-2-[3-[N-methyl-N-[2-[(3,4-methylenedioxy) phenoxy]ethyl]amino]propoxy]phenyl]-4-methyl-3-oxo-2H-1,4- benzothiazine (SD-3211), in rats, (+)-3,4-dihydro-2-[5-hydroxy-2-[3-[N-methyl-N-[2- [(3,4-methylenedioxy)-phenoxy]ethyl]amino]propoxy]phenyl]-4-methyl- 3-oxo-2H-1,4-benzothiazine((+)-I), (+)-3,4-dihydro-2-[5-hydroxy-2-[3-[N- [2-[(3,4-methylenedioxy) phenoxy]ethyl]amino] propoxy]-phenyl]-4-methyl-3-oxo-2H-1,4-benzothiazine((+)-II) and (+)-3,4-dihydro-2-[5-methoxy-2-[3-[N-[2-[(3,4-methylenedioxy) phenoxy]ethyl]amino]propoxy]phenyl]-4-methyl-3-oxo-2H-1,4- benzothiazine((+)-III) were synthesized. Compounds (+)-I, (+)-II and (+)-III were identified with the fecal metabolites M-I, M-II and M-III, respectively. The calcium antagonistic activities of (+)-I, (+)-II and (+)-III were examined.
