A Mixed-Methods Study Protocol for Soma Experiencing Motion Program (Soma e-motion Program): The Effectiveness of Contemplative Movement for Emotion Regulation.

Somatics refers to body work and movement study that emphasize internal perception and experience. Recently, a new perspective has emerged that views somatics-based techniques as a kind of mindful movement. Somatic techniques as contemplative movement can improve emotional regulation ability through improvement of body awareness or interoception. Based on this background, the present study attempts to develop a somatics based program suitable for a group of clinical patients suffering from emotional dysregulation. This study plans to collect quantitative and qualitative data in order to clarify how interoception and the related emotional regulation ability change after the program. These findings will help to explore whether the somatics technique has potential as an emotion regulation program in the future. In addition, the results are expected to contribute to finding an alternative treatment modality for patients who have not achieved a sufficient effect with conventional psychotherapy.

The Relationship between Adverse Childhood Experiences and Sleep Problems among Adolescent Students: Mediation by Depression or Anxiety.

Adverse childhood experiences (ACEs) are known to be closely related to depression, anxiety and sleep problems. However, it remains unclear whether adolescents with ACEs have sleep problems regardless of depression or anxiety or under a mediating effect from depression or anxiety. Therefore, our aim was to examine whether depression or anxiety mediates the relationship between ACEs and sleep problems in adolescents by using a community sample. The Early Trauma Inventory Self Report-Short Form (ETISR-SF) and List of Threatening Experiences Questionnaire (LTE-Q) were used to assess traumatic ACEs. Ultimately, data from 737 students (M = 448, F = 289, 15.1 ± 1.4 years old) were included in the statistical analysis. A total of 576 (78.1%) participants reported that they had experienced one or more ACEs. Adolescents with ACEs had higher levels of depression, anxiety and sleep problems than did adolescents without ACEs, and boys tended to experience more trauma than girls. Depression and anxiety partially mediated the relationship between ACEs and sleep problems. The results of this study suggest the need for depression and anxiety interventions for adolescents with ACEs to reduce the long-term consequences, including sleep problems and physical health problems.

Transgenerational Transmission of Trauma: Psychiatric Evaluation of Offspring of Former "Comfort Women," Survivors of the Japanese Military Sexual Slavery during World War II.

"Comfort women" are survivors of sexual slavery by the Imperial Japanese Army during World War II, who endured extensive trauma including massive rape and physical torture. While previous studies have been focused on the trauma of the survivors themselves, the effects of the trauma on the offspring has never been evaluated before. In this article, we reviewed the first study on the offspring of former "comfort women" and aimed to detect the evidence of transgenerational transmission of trauma. In-depth psychiatric interviews and the Structured Clinical Interview for DSM-5 Axis I Disorders were conducted with six offspring of former "comfort women." Among the six participants, five suffered from at least one psychiatric disorder including major depressive disorder, panic disorder, posttraumatic stress disorder, adjustment disorder, insomnia disorder, somatic symptom disorder, and alcohol use disorder. Participants showed similar shame and hyperarousal symptoms as their mothers regarding stimuli related to the "comfort woman" issue. Increased irritability, problems with aggression control, negative worldview, and low self-esteem were evident in the children of mothers with posttraumatic stress disorder. Finding evidence of transgenerational transmission of trauma in offspring of "comfort women" is important. Future studies should include more samples and adopt a more objective method.

The relation between immunologic variables and symptom factors in patients with major depressive disorder.

BACKGROUND: The associations between depression and immunity were investigated by measuring the scores of Hamilton Rating Scale for Depression (HRSD) and peripheral lymphocyte parameters in patients with major depressive disorder (MDD). METHODS: Forty-nine patients with MDD were recruited and their clinical symptoms are evaluated with 17-item HRSD which was factorized using the confirmatory factor analysis (i.e., depression factor, insomnia factor, and anxiety factor). Basic immunologic variables such as CD4, CD8, and CD56-positive cell numbers were measured by flow cytometry. Natural killer cell activity (NKCA) was also assessed by ELISA method using K-562 cells as target cells. All patients were treated for 4 weeks with selective serotonin reuptake inhibitors. Immunologic and clinical variables were measured both at baseline and after medication. RESULTS: CD8-positive cell number was increased (p < .05) and CD4/CD8 ratio was decreased (p < .01) after medication. NKCA showed a significant positive correlation with anxiety factor scores of HRSD (p < .05) at baseline. However, except NKCA, there was no correlation between other immunologic measures and symptom factors. CONCLUSION: These results suggest that immunologic measure such as NKCA may be an important variable for symptom of MDD such as anxiety during acute depressive state.

Psychiatric Sequelae of Former "Comfort Women," Survivors of the Japanese Military Sexual Slavery during World War II.

"Comfort women" refers to young women and girls who were forced into sexual slavery by the Imperial Japanese military during World War II. They were abducted from their homes in countries under Imperial Japanese rule, mostly from Korea, and the rest from China, Philippines, Malaysia, Taiwan, Indonesia, the Netherlands, etc. "Comfort women" endured extreme trauma involving rape, sexual torture, physical abuse, starvation, threats of death, and witnessed many others being tortured and killed. This article reviews all the studies that have investigated the psychiatric or psychosocial sequelae of the survivors of the Japanese military sexual slavery. Most importantly, a recent study which conducted a psychiatric evaluation on the former "comfort women" currently alive in South Korea is introduced. The participants' unmarried rate was relatively high and their total fertility rate was relatively low. Majority of the participants reported having no education and being the low economic status. They showed high current and lifetime prevalence of posttraumatic disorder, major depressive disorder, somatic symptom disorder, social anxiety disorder, panic disorder, and alcohol use disorder. Participants showed high suicidality and majority of the participants still reported being ashamed of being former "comfort women" after all these years. This article high-lights the fact that the trauma has affected the mental health and social functioning of former "comfort women" throughout their lives, and even to the present day.

Natural killer cell activity in patients with major depressive disorder treated with escitalopram.

BACKGROUND: An association between depression and altered immunity has been suggested by many studies, although the findings are not fully consistent. The present investigation examined the effects of escitalopram on cellular immunity in patients with major depressive disorder (MDD). METHODS: Fifty-one patients with MDD were evaluated with the Hamilton Rating Scale for Depression and Montgomery-Åsberg Depression Rating Scale. The patients were grouped into responders (n=32) and non-responders (n=19). Adrenocorticotropic hormone, cortisol, CD4, CD8, CD19, and natural killer cells were measured at baseline and after a 4 week treatment with escitalopram. Plasma hormones and immune parameters were compared between groups. RESULTS: Responders showed increased activity, but not number, of natural killer cells after a 4 week treatment with escitalopram. There were no differences in plasma hormones and other immune parameters between groups, even though cortisol was decreased and CD19 was increased across both groups compared to baseline. CONCLUSIONS: The results suggest that natural killer cells play an important role in improving the symptoms of depressive patients responding to selective serotonin inhibitors. To deepen our understanding of the pathogenesis of depression, interactions between serotonin and the immune system should be further explored.

The Difference in Comorbidities and Behavioral Aspects between Internet Abuse and Internet Dependence in Korean Male Adolescents.

OBJECTIVE: This study examined the differences in psychiatric comorbidities and behavioral aspects in accordance with the severity of Internet addiction in male adolescents. METHODS: One hundred and twenty-five adolescents from four middle and high schools in Seoul were enrolled in this study. The subjects were divided into non-addict, abuse, and dependence groups according to a diagnostic interview by psychiatrists. The psychiatric comorbidities and behavioral aspects of subjects were evaluated through psychiatric clinical interviews based on the Diagnostic and Statistical Manual of Mental Disorders (4th edition), the Children's Depression Inventory, the State-Trait Anxiety Inventory, the Internet Addiction Test, and a self-reported questionnaire about behavioral aspects. RESULTS: The psychiatric comorbidity distributions were significantly different in the abuse and dependence groups, particularly in terms of attention-deficit hyperactivity disorder and mood disorder items. The Children's Depression Inventory, the State-Trait Anxiety Inventory, and the Internet Addiction Test scores were also significantly different among the three groups. There were significant differences in 10 of the 20 items of the Internet Addiction Test between the non-addict, abuse, and dependence groups. There were significant differences in seven items between the non-addict and abuse groups, but no differences between subjects in the abuse and dependence groups. Significant differences were observed in three items between the abuse and dependence groups, but there were no significant differences between the non-addict and abuse groups. In terms of behavioral aspects, scores for abusive, sexual, and decreased social interest behaviors were highest in the dependence group, and lowest in the non-addict group. However, the behavioral aspects of decreased interpersonal relationships did not show this difference between groups. CONCLUSION: This study suggests that there are differences in psychiatric comorbidities and behavioral aspects between adolescent males with characteristics of Internet abuse and Internet dependence.

Aripiprazole augmentation for treatment of patients with chronic or recurrent major depressive disorder: a 12-week prospective open-label multicentre study.

Patients with chronic or recurrent major depressive disorder (MDD) have faced a dearth of treatment options. The present study evaluated the effectiveness and tolerability of aripiprazole augmentation for the treatment of chronic or recurrent MDD. This was the first 12-week prospective, multicentre, open-label study of the effectiveness and tolerability of flexibly dosed aripiprazole as an augmentation to ongoing antidepressant treatment in patients with chronic or recurrent MDD. The primary outcome measure for effectiveness was changes between baseline and endpoint (week 12) in total scores on the Montgomery-Asberg Depression Rating Scale. Adverse events (AEs) occurring throughout the trial are also reported. The Montgomery-Asberg Depression Rating Scale total scores decreased significantly between the baseline and the endpoint (magnitude of difference=-11.6, P<0.0001). At the endpoint, the response rate was 55.2% and the remission rate was 41.3%. Adjunctive aripiprazole treatment administered from week 1 through the endpoint was associated with remission and significant treatment responses. More than half (55.8%) of those taking adjunctive aripiprazole completed the study and relatively few patients discontinued participation because of AEs. None of the patients discontinued participation in the study because of an inadequate therapeutic response. Common AEs included headache, akathisia, insomnia and constipation. The mean dose of aripiprazole at the endpoint was 6.6 mg/day. Adjunctive aripiprazole may be effective and tolerable for patients with chronic or recurrent MDD. Adequately powered and controlled clinical trials should be conducted to confirm our open-label study findings.

Differences in Performance of ADHD Children on a Visual and Auditory Continuous Performance Test according to IQ.

OBJECTIVE: Continuous performance tests (CPTs) are frequently used in clinical practice to assess the attentiveness of ADHD children. Although most CPTs do not categorize T scores by intelligence, there is great diversity of opinion regarding the interrelation between intelligence and CPT performance. This study aimed to determine if ADHD children with superior IQs would perform better than ADHD children with average IQs. Additionally, we aimed to examine the need for CPTs' to categorize according to IQ. METHODS: Participants were 326 outpatients, aged 5-15 years, diagnosed with ADHD. All participants completed the Wechsler Intelligence Scale for Children-Revised and a CPT. After excluding those who meet exclusion criteria, we had 266 patients for our analysis. RESULTS: The "Highly Intelligent Group" (HIG), patients with IQs 120 and above, performed superiorly to the "Normally Intelligent Group" (NIG) patients, with IQs between 70 and 120, with regard to omission and commission errors on the visual-auditory CPT, even after controlling for age and gender. The HIG had higher ratios of subjects with T scores <65 on the visual and auditory CPT variables than the NIG did. CONCLUSION: The results of this study suggest this CPT is not sensitive for discerning ADHD in children with superior IQs; thus, there is a need to standardize the variables based on IQ, as well as on age and gender. Moreover, clinicians need to pay attention to the effect of IQ in interpreting CPT scores; that is, a "normal" score does not rule out a diagnosis of ADHD.

Preliminary study of Internet addiction and cognitive function in adolescents based on IQ tests.

The potential relationship between Internet addiction and certain cognitive function problems has been suggested by several studies. However, few or no studies have examined the differences in cognitive functioning between persons addicted to the Internet and persons not addicted using a standard neuropsychological test. This study screened 253 middle school students and 389 high school students for Internet addiction and compared 59 Internet-addicted students with 43 non-addicted students using an IQ test. The Internet-addicted group had comprehension sub-item scores that were significantly lower than those of the non-addicted group. As the comprehension item reflects ethical judgement and reality testing, there may be a relationship between Internet addiction and weak social intelligence. Earlier onset of Internet addiction and longer addiction duration were associated with lower participant performance in areas related to attention. As this study is a cross-sectional study, it is not clear whether the persons who display weak cognitive functioning are susceptible to Internet addiction or if Internet addiction causes cognitive problems. However, as brain development remains active during adolescence, the possibility that Internet addiction adversely affects the cognitive functioning of adolescents cannot be ruled out.

Auditory and visual P300 reflecting cognitive improvement in patients with schizophrenia with quetiapine: a pilot study.

We recorded event-related potentials (ERPs) in patients with schizophrenia before and after treatment with quetiapine, to investigate this drug's effects on cognitive function. Auditory and visual oddball stimulus discrimination paradigms were presented to patients with schizophrenia (N=20) before and after 3months' treatment with quetiapine. The 2-stimulus auditory oddball paradigm used a standard tone (1000Hz, 75dB, 80%) and a target tone (2000Hz, 75dB, 20%). The 2-stimulus visual oddball paradigm used a standard stimulus (small circle, 80%) and a target stimulus (large circle, 20%). Patients' severity of psychopathology was initially evaluated with the Positive and Negative Syndrome Scale (PANSS) and was likewise re-evaluated after treatment. After treatment with quetiapine, patients' P300 amplitudes increased over baseline for both tasks (auditory stimuli, P<0.01; visual stimuli, P<0.01) and their P300 latencies for both target stimuli decreased significantly (auditory stimuli, P<0.001; visual stimuli, P<0.01). Visual P300 amplitude was negatively correlated with the severity of positive symptoms at the Fz electrode before the treatment (r=-0.45, P<0.05). After treatment with quetiapine, there were no significant correlations between severity of positive or negative symptoms and visual P300 amplitudes for midline electrodes. These findings suggest that the reduced and delayed P300 may be a state marker for schizophrenia, which may in turn be modulated by positive symptoms, and also suggest that the amplitude and latency for both auditory and visual tasks may be decreased by quetiapine treatment. Based on these results, we suggest that the atypical antipsychotic quetiapine may improve some aspects of cognitive domains in patients with schizophrenia.

Effects of chromosomal variations on pharmacokinetic activity of zolpidem in healthy volunteers: an array-based comparative genomic hybridization study.

Zolpidem has been known as a very safe and effective hypnotic drug used to treat a variety of patients with insomnia. Even though the same dose of the medicine is administered to each patient, the blood level of zolpidem and the time required to obtain peak concentration are not consistent among different people. We evaluated the relationship between the peak concentrations of zolpidem and chromosomal imbalances using a high-resolution genome-wide array-based comparative genomic hybridization (CGH) in 16 healthy volunteers in order to detect the genetic factors underlying the variations. The present study showed that chromosomal losses were detected in the 4q35.2, 9p13.1 and 9p12 regions, and those gains were indicated in the 2p14, 11q13.4 and 15q11.2 regions. The abnormal regions were confirmed by fluorescence in situ hybridization (FISH) and real-time PCR. It is suggested that array-CGH analysis may be used as a measure for pharmacogenomic applications in the patients with insomnia and for further exploration of candidate genomic regions implicated in sleep disturbances.

Natural Killer T cells in patients with major depressive disorder.

CD56 (Natural Killer T) cells showed a significant negative correlation with depressive symptom scale scores in acute and unmedicated patients with major depressive disorder. Decreased CD56 cells may reflect the severity of depressive symptoms but not the severity of anxiety symptoms in major depression.
