Efficacy and Safety of Escitalopram, Desvenlafaxine, and Vortioxetine in the Acute Treatment of Anxious Depression: A Randomized Rater-blinded 6-week Clinical Trial

Objective@#Anxious depression is associated with greater chronicity, higher severity of symptoms, more severe functional impairment, and poor response to drug treatment. However, evidence for first-choice antidepressants in patients with anxious depression is limited. This study aimed to compare the efficacy and safety of escitalopram, desvenlafaxine, and vortioxetine in the acute treatment of anxious depression. @*Methods@#Patients (n = 124) with major depressive disorder and high levels of anxiety were randomly assigned to an escitalopram treatment group (n = 42), desvenlafaxine treatment group (n = 40), or vortioxetine treatment group (n = 42) in a 6-week randomized rater-blinded head-to-head comparative trial. Changes in overall depressive and anxiety symptoms were assessed using the 17-item Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA), respectively. @*Results@#Patients demonstrated similar baseline-to-endpoint improvement in scores and similar response and remission rates for HAMD and HAMA. Analysis of the individual HAMD items revealed that desvenlafaxine significantly reduced anxiety somatic scores (p= 0.013) and hypochondriasis scores (p = 0.014) compared to escitalopram. With respect to the individual HAMA items, desvenlafaxine treatment showed significantly lower scores for respiratory symptoms (p = 0.013) than escitalopram treatment and cardiovascular symptoms (p = 0.005) than vortioxetine treatment. The treatments were well tolerated, with no significant differences. @*Conclusion@#Our results indicated no significant differences in the efficacy and tolerability of escitalopram, desvenlafaxine, and vortioxetine in this subtype of patients with anxious depression during the acute phase of treatment.

Characteristics of Korean Employees Without Depression but Having Suicidal Ideation

Objective@#The aim of this study was to identify the factors related to suicidal ideation targeting the risk group showing suicidal ideation despite the absence of depression in Korean workers. @*Methods@#The data of 14,425 participants who were employees aged of 18 to 75 years who attended a mental health checkup program at the Workplace Mental Health Institute, Kangbuk Samsung Hospital from June 2015 to October 2019 were analyzed. A self-report questionnaire consisting of sociodemographic factors, suicidal ideation, job stress, levels of depression and anxiety, and resilience was administered. A Hierarchical logistic regression model was used with suicidal ideation as dependent variable. Separate analyses were conducted according to depressive symptoms using the 20-item Center for Epidemiological Studies Depression (CES-D) scale. @*Results@#Being women, older, and having low resilience, more perceived stress, more severe anxiety and less sleeping hours were associated with suicidal ideation in no-depression group (CES-D <16). In the subcategories of job stress, lack of reward was significantly associated with suicidal ideation in no-depression group. @*Conclusion@#This study identified the characteristics of a group that has no depression but has suicidal ideation in Korean workers. Among job stress items, lack of reward is a clear characteristic to be considered with caution in this group.

Acute Efficacy and Safety of Escitalopram Versus Desvenlafaxine and Vortioxetine in the Treatment of Depression With Cognitive Complaint: A Rater-Blinded Randomized Comparative Study

Objective@#This study aimed to compare the efficacy and safety of escitalopram, vortioxetine, and desvenlafaxine for acute treatment of major depressive disorder (MDD) with cognitive complaint (CC). @*Methods@#A total of 129 patients with MDD who also complained of CC were randomized evenly to either escitalopram, vortioxetine, or desvenlafaxine group and underwent a multi-center, six-week, rater-blinded, and head-to-head comparative trial. Differences in depressive symptoms following treatment were measured using the Hamilton Depression Rating Scale (HAMD) and the Montgomery-Åsberg Depression Rating Scale (MADRS). Subjective cognitive function and the presence of adverse events were assessed. @*Results@#The three antidepressant treatment groups did not show significant differences in the improvement of depressive symptoms as measured by HAMD and MADRS. Desvenlafaxine treatment was associated with a superior treatment response rate in depressive symptoms compared to vortioxetine or escitalopram treatment. However, no significant differences were found in the remission rate of depressive symptoms. The three antidepressant treatment groups did not show significant differences in the improvement of CC. Adverse profiles of each treatment group were tolerable, with no significant differences. @*Conclusion@#In acute antidepressant treatment for MDD with CC, escitalopram, vortioxetine, and desvenlafaxine presented similar efficacy in relief of depressive symptoms; however, desvenlafaxine was associated with a superior treatment. Further studies are needed to confirm these results by investigating the therapeutic efficacy and safety profile of long-term antidepressant treatment of MDD with CC (Clinical Trial Registry, http://cris.nih.go.kr/cris/en/: KCT0002173).

The Association Between Alcohol Use and Suicidal Ideation Among Employees

Objective@#The risk of suicide is assessed by identifying the relationship between alcohol-use patterns and suicidal ideation in Korean employees. @*Methods@#The study involved 13,858 employees who underwent workplace mental health screening at the Workplace Mental Health Institute of Kangbuk Samsung Hospital over a 6-year period between 2014 and 2019. Analysis was performed separately for Alcohol Use Disorders Identification Test-Korea (AUDIT-K) items related to the frequency/volume of alcohol consumption (items 1 to 3, AUDIT-C) and those regarding alcohol dependence/related problems (items 4 to 10, AUDIT-D/P). Subjects were then classified into three groups on the basis of the presence or absence of clinical depression and suicidal ideation. The groups’ sociodemographic factors and clinical features of depression, anxiety, and alcohol-use patterns were analyzed with a chi-square test as well as one-way analysis of variance, followed by a post hoc test using the Bonferroni correction. @*Results@#AUDIT-K and AUDIT-D/P scores were significantly associated with the presence or absence of clinical depression as well as the presence or absence of suicidal ideation (p<0.05). However, no significant differences were found among the three groups with regard to the AUDIT-C score (p=0.054). @*Conclusion@#Identifying or treating alcohol dependence/related problems can help lower the occurrence of mental health problems, and suicidal ideation in particular, in employees and reduce social costs.

Additional Reduction of Residual Symptoms with Aripiprazole Augmentation in the Patients with Partially Remitted Major Depressive Disorder

Objective@#Many patients with major depressive disorder (MDD) suffer from residual symptoms without achieving remission. However, pharmacologic options for residual symptoms of MDD have been limited. This study aimed to investigate benefit of aripiprazole augmentation in the treatment of residual symptoms in the patients with partially remitted MDD. @*Methods@#We retrospectively analyzed the 8-week medical records of the patients. The enrolled patients did respond to treatment of antidepressant but were not remitted. The range of 17-item Hamilton Depression Rating Scale (HAMD) total score of the subjects were 8 to 15 points. All patients were currently taking antidepressants when they started aripiprazole. The primary endpoint was the mean change of Clinically Useful Depression Outcome Scale (CUDOS).Secondary endpoint measures were HAMD, Clinical Global Impression-severity (CGI-S) scores, Patient Health Questionnaire-15 (PHQ-15), Beck Anxiety Inventory (BAI), Perceived Deficit Questionnaire-depression (PDQ-D), Sheehan Disability Scale (SDS) and General Health Questionnaire/Quality of Life-12 (GHQ/QL-12). @*Results@#A total of 134 medical records were analyzed. The changes of CUDOS, HAMD, CGI-S, BAI, PHQ-15, PDQ-D, SDS and GHQ/QL-12 from baseline to the endpoint were −7.93, −3.29, −0.80, −4.02, −2.05, −4.35, −4.77 and −2.82, respectively (all p ＜ 0.001). At the endpoint, the newly remitted subjects rate by HAMD score criteria were approximately 46%. @*Conclusion@#Our preliminary findings have presented the effectiveness of aripiprazole augmentation for residual symptoms of partially remitted MDD patients in routine practice. This study assures subsequent well-controlled studies of the possibility of generalizing the above promising outcome in the future.

Changes in Brain Electrical Activity According to Post-traumatic Stress Symptoms in Survivors of the Sewol Ferry Disaster: A 1-year Longitudinal Study

Objective@#The pathology of post-traumatic stress disorder (PTSD) is associated with changes in brain structure and function, especially in the amygdala, medial prefrontal cortex, hippocampus, and insula. Survivors of tragic accidents often experience psychological stress and develop post-traumatic stress symptoms (PTSS), regardless of the diagnosis of PTSD. This study aimed to evaluate electroencephalographic changes according to PTSS in victims of a single traumatic event. @*Methods@#This study enrolled 60 survivors of the Sewol ferry disaster that occurred in 2014 from Danwon High School and collected electroencephalographic data through 19 channels twice for each person in 2014 and 2015 (mean 451.88 [standard deviation 25.77] days of follow-up). PTSS was assessed using the PTSD Checklist-Civilian Version (PCL-C) and the participants were divided into two groups according to the differences in PCL-C scores between 2014 and 2015. Electroencephalographic data were converted to three-dimensional data to perform low-resolution electrical tomographic analysis. @*Results@#Significant electroencephalographic changes over time were observed. The group of participants with worsened PCL-C score showed an increased change of delta slow waves in Brodmann areas 13 and 44, with the largest difference in the insula region, compared to those with improved PCL-C scores. @*Conclusion@#Our findings suggests that the electrophysiological changes in the insula are associated with PTSS changes.

The Association between Physical Activity and Anxiety Symptoms for General Adult Populations: An Analysis of the Dose-Response Relationship

Objective@#The aim of this study is to determine the dose-response relationship between physical activity and anxiety symptoms. @*Methods@#We included data of 124,434 participants who had comprehensive health-screening examinations from January 1st, 2012, to December 31st, 2016, in Kangbuk Samsung Hospital, Seoul and Suwon, South Korea. We measured the level of physical activity using the International Physical Activity Questionnaire-short form (IPAQ-SF) and estimated anxiety symptoms using the Beck Anxiety Inventory (BAI). BAI scores of 19 and above were defined as cases. Logistic regression was used to analyze the association between physical activity and BAI-defined anxiety. Furthermore, we assessed whether sex differences might affect the relationship between physical activity and BAI-defined anxiety by stratifying our data. @*Results@#Compared with the sedentary group (0–600 METs-min/week), individuals achieving 600–6,000 METs-min/wk had a significantly lower risk of BAI-defined anxiety with a U-shaped relationship in general adults. After stratifying our data by sex, we found that optimal ranges of physical activity were 600–9,000 METs-min/wk for men, but 1,200–3,000 METs-min/wk for women. @*Conclusion@#We identified a U- or J-shaped association between physical activity and anxiety symptoms, suggesting an optimal dose and upper limit of physical activity for decreasing anxiety symptoms. Optimal levels and upper limits of physical activity for reducing anxiety symptoms were higher for men than for women.

Resilience as a Protective Factor for Suicidal Ideation among Korean Workers

Objective@#This study aimed to investigate resilience as a protective factor for suicidality among Korean workers. @*Methods@#Participants were workers from 26 organizations in Korea, aged 18 to 63 years, who completed a self-reported questionnaire comprising items on sociodemographic factors, job stress, resilience, and suicidality. Completed questionnaires were collected from 4,405 persons, with 4,389 valid responses. Hierarchical logistic regression analyses were performed using suicidality as the dependent variable. @*Results@#Results of the logistic regression analyses indicated that among the sociodemographic factors, older age, being female, and being single were statistically significantly associated with suicidal ideation. A high level of job stress, depressive mood, and anxiety, in addition to a short job duration, were also associated with suicidal ideation. Resilience was a significant protective factor for suicidal ideation after adjusting for all other variables. Older age and high anxiety levels were associated with having a suicide plan among participants with suicidal ideation. The association of resilience with suicide plans and suicide attempts was non-significant. @*Conclusion@#In this study, we found that a high level of resilience was associated with a low incidence of suicidal ideation in Korean workers. Based on these results, we suggest the need to develop and implement interventions to improve resilience in the workplace, thereby protecting workers, especially those with a high level of work stress, from suicidal ideation.

The Relationship between Serum Vitamin D Levels,C-Reactive Protein, and Anxiety Symptoms

Objective@#The aim of study is to investigate the relationship between serum vitamin D, c-reactive protein (CRP) levels, and anxietysymptoms. @*Methods@#Serum vitamin D and CRP levels of 51,003 Korean adult participants were collected retrospectively. Anxiety symptoms wereassessed using the Korean version of Beck Anxiety Inventory. Logistic regression was used to estimate the odds ratio (ORs) of anxietysymptoms by serum vitamin D and CRP levels. The regression was adjusted for covariates, and each model was adjusted mutually for vitaminD and CRP levels. @*Results@#Compared with sufficient vitamin D levels (≥20 ng/mL), insufficient (10–19.99 ng/mL) and deficient (<10 ng/mL) vitamin Dlevels were significantly associated with risk of anxiety symptoms. Also, continuous vitamin D levels were negatively associated with therisk of anxiety symptoms. CRP levels did not affect the relationship between vitamin D levels and risk of anxiety symptoms. @*Conclusion@#Insufficient (10–19.99 ng/mL) and deficient (<10 ng/mL) vitamin D levels were significantly associated with risk of anxietysymptoms. After adjusting for CRP levels, the results were not changed, and no evidence of interaction between vitamin D and CRP levelswas found. CRP levels did not account for the association between vitamin D levels and risk of anxiety symptoms.Psychiatry Investig 2020;17(4):312-319

Anti-LGI1 Antibody Encephalitis

Leucine rich glioma inactivated (LGI1) encephalitis is an uncommon neurological disorder rarely encountered in clinical practice.However, it is a potentially fatal autoimmune syndrome that can decrease the level of consciousness, possibly progressing to coma.Additionally, unless diagnosed and promptly treated, it can cause permanent cognitive impairment. Since LGI1 encephalitis can initially present with psychiatric symptoms, there can be delays in reaching a proper diagnosis. This report describes a case of a 47-yearold woman with LGI1 antibodies-associated limbic encephalitis who initially presented with psychosis. Her blood tests were normal and no MRI and EEG abnormalities were found. Cerebrospinal fluid analysis was negative for other possible infectious causes. Three months after admission, she was found to be LGI1 antibody positive. LGI1 encephalitis should be suspected in patients with symptoms such as memory loss, confusion, seizures, and psychiatric symptoms. Prompt diagnosis and treatment of LGI1 encephalitis are warranted because prognosis becomes worse when such actions are delayed.

Resilience as a Protective Factor for Depressive Mood and Anxiety among Korean Employees

BACKGROUND: This study aimed to investigate resilience as a protective factor for depressive mood and anxiety among Korean employees. METHODS: Participants were employees of eight private and local government organizations in Korea, aged 19 to 65 years. A self-report questionnaire that included items on resilience, job stress, levels of depression and anxiety, and socio-demographic factors, was administered to 1,079 Korean employees, with 1,076 valid responses. We performed hierarchical linear regression analyses with the levels of depression and anxiety scores as dependent variables. RESULTS: Being women and having a high level of job stress were associated with greater depressive mood and anxiety. In contrast, resilience was negatively related to depressive mood and anxiety, after adjusting for demographic variables and the level of job stress. Among the five factors for resilience, “support” and “hardiness” were protective factors for depressive mood and anxiety after adjusting for demographic variables and the level of job stress. CONCLUSION: Based on the results of the current study, we suggest that focusing on the resilience of employees, especially on “support” and “hardiness,” factors as well as developing and engaging in interventions that increase resilience in the workplace, can protect against depressive mood and anxiety, especially for those with high levels of job stress.

The Development of Evidence-Based Guideline for Diagnosis and Management of Headache in Korea

OBJECTIVE: We aimed to develop the clinical guideline for headache by the systematic review and synthesis of existing evidence-based guidelines. The purpose of developing the guideline was to improve the appropriateness of diagnosis and treatment of headache disorder, and consequently, to improve patients’ pain control and quality of life. The guideline broadly covers the differential diagnosis and treatment of tension-type headache, migraine, cluster headache, and medication-overuse headache. METHODS: This is a methodological study based on the ADAPTE methodology, including a systematic review of the literature, quality assessment of the guidelines using the Appraisal of Clinical Guidelines for REsearch & Evaluation II (AGREE II) Instrument, as well as an external review using a Delphi technique. The inclusion criteria for systematic search were as follows: topic-relevant, up-to-date guidelines including evidence from within 5 years, evidence-based guidelines, guidelines written in English or Korean, and guidelines issued by academic institutions or government agencies. RESULTS: We selected five guidelines and conducted their quality assessment using the AGREE II Instrument. As a result, one guideline was found to be eligible for adaptation. For 13 key questions, a total of 39 recommendations were proposed with the grading system and revised using the nominal group technique. CONCLUSION: Recommendations should be applied to actual clinical sites to achieve the ultimate goal of this guideline; therefore, follow-up activities, such as monitoring of guideline usage and assessment of applicability of the recommendations, should be performed in the future. Further assessment of the effectiveness of the guideline in Korea is needed.

Characteristics of Residual Symptoms in Korean Patients with Major Depressive Disorder: A Validation Study for the Korean Version of Depression Residual Symptom Scale

OBJECTIVE: Residual symptoms of depression are related to more severe and chronic course of functional impairment with higher risk of relapse. The objective of this study was to validate, and determine psychometric properties of the Korean version of Depression Residual Symptom Scale (KDRSS). METHODS: A total of 203 outpatients with recent episode of major depression based on DSM-IV criteria were enrolled in this study. They had been treated with antidepressants and assessed by KDRSS, Hamilton Depression Rating Scale-24 (HDRS-24), and Montgomery-Åsberg Depression Rating Scale (MARDS). The validity and reliability of KDRSS were assessed, including internal consistency reliability, concurrent validity, temporal stability, factorial validity, and discriminative validity. RESULTS: Internal consistency (Cronbach’s alpha=0.961), concurrent validity (MADRS: r=0.731, p < 0.01, HDRS-24: r=0.663, p < 0.01), and temporal stability (r=0.726, p < 0.01) of KDRSS were all excellent. KDRSS showed good discriminative validity based on MARDS. KDRSS consisted of one-factor structure accounting for 63.8% of total variance. All subjects except two in full remission group had one or more residual symptoms. In 7 subscales of KDRSS consisting of similar items respectively, ‘lack of energy’ was the most commonly reported, followed by ‘increased emotionalism’ in this group. CONCLUSION: KDRSS is a useful and sensitive instrument for measuring residual depressive symptoms. Since some depressive symptoms including ‘lack of energy’ and ‘increased emotionalism’ in patients with full remission might be persistent during psychiatric intervention, these symptoms need to be focused on in clinical practice.

Application of Assessment Tools to Examine Mental Health in Workplaces: Job Stress and Depression

Despite the fact that the lifetime and yearly prevalence rates of mental illness continue rising, such diseases have only been acknowledged as involved in workplace health issue since the 2000s. Additionally, while the number of recognized cases of mental illnesses is rather low compared to their prevalence, they have a high likelihood of causing significant problems, including fatalities. Many workers are terrified of losing their jobs due to mental illness and therefore attempt to hide their mental health problems. For this reason, clinicians involved in occupational and environmental medicine should focus on interviews or screenings to identify such hidden mental health problems. More specifically, it would be helpful to evaluate job stress and depression in workplaces to ensure appropriate preventive actions and thereby reduce the prevalence of mental illness. Job stress not only causes mental illness and dissatisfaction with work, but also can increase the prevalence and morbidity of medical diseases, as well as other physical health problems. Depression is a major contributor to work loss and absence with effects surpassing almost all of the chronic medical disorder. These facts show why measure of job stress and depression should be highlighted in the occupational settings. This article introduces a variety of assessment tools to examine mental health, particularly stress and depression, in workplaces. These tools can be used by clinicians or professionals involved in the mental health, occupational safety, or health service fields for running diagnostics or screening tests.

Natural Course of Posttraumatic Symptoms in Late-Adolescent Maritime Disaster Survivors: Results of A 12-Month Follow-Up Study

OBJECTIVE: This study is a prospective observational study on 75 late-adolescent survivors of a large passenger ship accident from immediately after the accident to one year later. METHODS: Assessments of student survivors were conducted on day 2 and at months 1, 6, and 12. The PTSD Checklist (PCL), Patient Health Questionnaire-9 (PHQ-9), State subscale of the State and Trait Anxiety Inventory (STAI-S), Athens Insomnia Scale (AIS), and Brief Resilience Scale (BRS) were administered. RESULTS: When the assessments for day 2 and month 12 were compared, all the scales, except the PCL-avoidance subscale, showed a significant improvement in symptoms among males. However, among females, all the scales, except the PCL-re-experience subscale and the STAI-S, failed to show a significant improvement. All the symptoms for both males and females showed a pattern that decreased to the lowest level at month 1 (camp-based controlled intervention period), then increased at months 6 and 12 (voluntary individual treatment after returning to school). CONCLUSION: The rapid deterioration of psychological symptoms was found during the chronic phase, when students returned to their daily routines and received voluntary individual therapy. There is a need to screen high-risk adolescents and be more attentive to them during this period.

Does Type D Personality Impact on the Prognosis of Patients Who Underwent Catheter Ablation for Atrial Fibrillation? A 1-Year Follow-Up Study

OBJECTIVE: Although Type D personality has been associated with the prognosis of various cardiac diseases, few studies have investigated the influence of Type D personality on the cardiac and psychiatric prognoses of patients with atrial fibrillation (AF). METHODS: Depression, anxiety, and quality of life were measured at baseline and 6 months. The recurrence of AF was measured during 1-year following radiofrequency catheter ablation (RFCA) for AF. The Kaplan-Meier method with log-rank tests were used to compare the cumulative recurrence of AF. ACox proportional hazard model was conducted to identify factors that contribute to the recurrence of AF. RESULTS: A total of 236 patients admitted for RFCA were recruited. Patients with a Type D personality had higher levels of depression and anxiety and a poorer quality of life compared to controls. Although depression, anxiety, and quality of life had improved 6 months after RFCA, significant differences in psychiatric symptoms remained between patients with and without Type D personality. In the Cox models, the type of AF was the only factor that influenced the recurrence of AF. CONCLUSION: Our results suggest that Type D personality predominately influences psychological distress in patients with AF, but not the recurrence of AF.

Eye Movement Desensitization and Reprocessing to Facilitate Posttraumatic Growth: A Prospective Clinical Pilot Study on Ferry Disaster Survivors

OBJECTIVE: The purpose of this study was to investigate the therapeutic effects of eye movement desensitization and reprocessing (EMDR) on post-traumatic growth (PTG). METHODS: This study was conducted using a sample of ten survivors of a large-scale maritime disaster that occurred in the Yellow Sea, South Korea, in April 2014. A total of eight EMDR sessions were administered by a psychiatrist at two-week intervals over a period of five months, starting two or three months after the accident. Post-Traumatic Growth Inventory (PTGI), Stress-Related Growth Scale (SRGS), Clinician-Administered PTSD Scale (CAPS), and Connor-Davidson Resilience Scale (CD-RISC) were measured before treatment, after sessions 4 and 8, and at three months after treatment completion. RESULTS: After three months from treatment completion, significant increases were observed in PTG (PTGI: Z(8)=−2.380, p=0.017; SRGS: Z(8)=−2.380, p=0.017) and resilience (CD-RISC: Z(8)=−2.386, p=0.017). A decrease in post-traumatic stress disorder (PTSD) level was also significant (CAPS: Z(8)=−2.176, p=0.030). The reduction of CAPS scores was correlated with increases of PTGI (rho=0.78, p=0.023) and SRGS (rho=0.79, p=0.020) scores. The changes in CAPS, PTGI, and SRGS scores between time point of end 8-session and three months follow-up was not significant (all p>0.05). Subjects with higher pre-treatment CD-RISC scores showed more significant improvements in PTGI (rho=0.88, p=0.004) and SRGS (rho=0.83, p=0.010) scores after treatment than did those with lower pre-treatment CD-RISC scores. CONCLUSION: EMDR therapy using standard protocol for trauma processing helped facilitating PTG in disaster survivors. To generalize these findings, further controlled studies comparing with other treatment modalities for PTSD are needed.
