ABSTRACT

Objective@#This study aimed to explore the characteristics and factors related to changes in cognitive function in vulnerable individuals with cognitive impairment during the coronavirus disease 2019 (COVID-19) pandemic. @*Methods@#Among patients who visited a local university hospital with subjective cognitive complaints, those who had been tested for cognitive function at least once after the onset of COVID-19 and tested regularly at least three times within the last 5 years were included (1st, the initial screening; 2nd, the test immediately before the COVID-19 pandemic; 3rd, the most recent test after the pandemic). Finally, 108 patients were included in this study. They were divided into groups according to whether the Clinical Dementia Rating (CDR) was maintained/improved and deteriorated. We investigated the characteristics of the changes in cognitive function and related factors during COVID-19. @*Results@#When comparing CDR changes before and after COVID-19, there was no significant difference between the two groups (p=0.317). Alternatively, the main effect of the time when the test was conducted was significant (p<0.001). There was also a significant difference in the interaction between the groups and time. When the effect of the interaction was analyzed, the CDR score of the maintained/ improved group significantly decreased before COVID-19 (1st–2nd) (p=0.045). After COVID-19 (2nd–3rd), the CDR score of the deteriorated group was significantly higher than that of the maintained/improved group (p<0.001). Mini-Mental State Examination recall memory and changes in activity during COVID-19 were significantly associated with CDR deterioration. @*Conclusion@#Memory dysfunction and decreased activity during the COVID-19 pandemic are strongly related to the deterioration of cognitive impairment.

ABSTRACT

Objective@#: The aim of this study was to verify the equivalence and effectiveness of the tablet-administered Korean Repeatable Battery for the Assessment of Neuropsychological Status (K-RBANS) for the prevention and early detection of dementia. @*Methods@#: Data from 88 psychiatry and neurology patient samples were examined to evaluate the equivalence between tablet and paper administrations of the K-RBANS using a non-randomly equivalent group design. We calculated the prediction scores of the tablet-administered K-RBANS based on demographics and covariate-test scores for focal tests using norm samples and tested format effects. In addition, we compared the receiver operating characteristic curves to confirm the effectiveness of the K-RBANS for preventing and detecting dementia. @*Results@#: In the analysis of raw scores, line orientation showed a significant difference (t=-2.94, p<0.001), and subtests showed small to large effect sizes (0.04–0.86) between paper- and tablet-administered K-RBANS. To investigate the format effect, we compared the predicted scaled scores of the tablet sample to the scaled scores of the norm sample. Consequently, a small effect size (d≤0.20) was observed in most of the subtests, except word list and story recall, which showed a medium effect size (d=0.21), while picture naming and subtests of delayed memory showed significant differences in the one-sample t-test. In addition, the area under the curve of the total scale index (TSI) (0.827; 95% confidence interval, 0.738–0.916) was higher than that of the five indices, ranging from 0.688 to 0.820. The sensitivity and specificity of TSI were 80% and 76%, respectively. @*Conclusion@#: The overall results of this study suggest that the tablet-administered K-RBANS showed significant equivalence to the norm sample, although some subtests showed format effects, and it may be used as a valid tool for the brief screening of patients with neuropsychological disorders in Korea.

ABSTRACT

Objective@#: This study aimed to validate the Korean version of the Repeatable Battery for the Assessment of Neuropsychological Status Update (K-RBANS). @*Methods@#: We performed a retrospective analysis of 283 psychiatric and neurosurgery patients. To investigate the convergent validity of the K-RBANS, correlation analyses were performed for other intelligence and neuropsychological test results. Confirmatory factor analysis was used to test a series of alternative plausible models of the K-RBANS. To analyze the various capabilities of the K-RBANS, we compared the area under the receiver operating characteristic (ROC) curves (AUC). @*Results@#: Significant correlations were observed, confirming the convergent validity of the K-RBANS among the Total Scale Index (TSI) and indices of the K-RBANS and indices of intelligence (r=0.47–0.81; p<0.001) and other neuropsychological tests at moderate and above significance (r=0.41–0.63; p<0.001). Additionally, the results testing the construct validity of the K-RBANS showed that the second-order factor structure model (model 2, similar to an original factor structure of RBANS), which includes a first-order factor comprising five index scores (immediate memory, visuospatial capacity, language, attention, delayed memory) and one higher-order factor (TSI), was statistically acceptable. The comparative fit index (CFI) (CFI, 0.949) values and the goodness of fit index (GFI) (GFI, 0.942) values higher than 0.90 indicated an excellent fit. The root mean squared error of approximation (RMSEA) (RMSEA, 0.082) was considered an acceptable fit. Additionally, the factor structure of model 2 was found to be better and more valid than the other model in χ2 values (Δχ2=7.69, p<0.05). In the ROC analysis, the AUCs of the TSI and five indices were 0.716–0.837, and the AUC of TSI (AUC, 0.837; 95% confidence interval, 0.760–0.896) was higher than the AUCs of the other indices. The sensitivity and specificity of TSI were 77.66% and 78.12%, respectively. @*Conclusion@#: The overall results of this study suggest that the K-RBANS may be used as a valid tool for the brief screening of neuropsychological patients in Korea.

ABSTRACT

Objectives@#:Suicide attempt history is one of the major suicide risk factors and the suicide mortality rate increases with the number of suicide attempts. This study aimed to compare demographic and clinical factors between first and multiple suicide attempters and investigate risk factors for multiple suicide attempts. @*Methods@#:Participants were 537 patients who were admitted to an emergency room after attempting suicide and divided into two groups (393 first attempters and 144 multiple attempters). Demographic factors, clinical characteristics, and suicide-related characteristics were compared between the two groups. Variables with a p-value lower than 0.1 were included in a multivariate logistic regression analysis. Logistic regression models were considered to identify independent risk factors for multiple suicide attempts. The significance level was set to 0.05. @*Results@#:Among demographic factors, the two groups differed in age, sex, education, occupation, and marital and cohabitation status. Multiple attempters were more likely to have a mental disorder, current use of psychiatric medication, interpersonal and psychiatric motivation for suicide, current suicidal thoughts, help seeking behavior, awareness of suicide, and agreement with psychiatric follow up. In the regression analysis, unmarried status, mental disorder, interpersonal or psychiatric stress, help seeking behavior, and antidepressant use emerged as significant risk factors of multiple suicide attempts. @*Conclusion@#:The study’s findings suggested that there are differences in the demographic and clinical characteristics of first and multiple suicide attempters. Specific strategies that consider unmarried status, mental disorder, interpersonal or psychiatric stress, help seeking behavior, and antidepressant use may be valuable for future suicide prevention.

ABSTRACT

Objective@#There have been many biological studies on suicide behaviors of borderline personality disorder (BPD), however few studies have sought to psychoanalytic characteristics including defense mechanisms. Therefore, we investigated psychological, symptomatic, and personality characteristics including defense mechanisms in suicide attempters and non-suicide attempters among patients with BPD. @*Methods@#We enrolled 125 patients with BPD. Forty-two patients with a history of one or more suicide attempts formed the suicide attempters group and 83 patients with no such history formed the non-suicide attempters group. We collated the differences in clinical and psychological characteristics between the two groups by using the Symptom Checklist-90-Revised (SCL-90-R), the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the Personality Disorder Questionnaire-4+ (PDQ-4+), and the Defense Style Questionnaire (DSQ). @*Results@#The suicide attempters group scored higher on the hostility subscale of SCL-90-R. The suicide attempters group also scored higher on the Infrequency, Back Infrequency, Lie, Masculinity-femininity, Paranoia, Psychasthenia, and Schizophrenia scales of the MMPI-2. The incidence of paranoid and antisocial personality disorders, as assessed by the PDQ-4+, was significantly different in both groups. Maladaptive, self-sacrificing defense style, splitting and affiliation on the DSQ were also higher for the suicide attempters group. In the results of the logistic regression analysis, gender, the F(B) and L scales on the MMPI-2, and ‘splitting of other’s image’ defense mechanism on the DSQ were the factors that significantly influenced to suicide attempts. @*Conclusion@#These findings suggest that impulsive psychiatric features and maladaptive defense style may be related to suicidal risk in patients with BPD. Therefore, our findings may help clinicians in estimating the risk of suicide in patients with BPD.

ABSTRACT

BACKGROUND: We evaluated the effects of neurofeedback as an augmentation treatment on depressive symptoms and functional recovery in patients with treatment-resistant depression (TRD). METHODS: We included 24 adult patients with TRD and 12 healthy adults. 24 TRD patients were assigned to the neurofeedback augmentation group (n = 12) and the medication-only (treatment as usual [TAU]) group (n = 12). The neurofeedback augmentation group underwent combined therapy comprising medication and 12–24 sessions of neurofeedback training for 12 weeks. To assess the serum levels of brain-derived neurotrophic factor (BDNF) in both groups, pre- and post-treatment blood samples were obtained. Patients were evaluated using the Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory (BDI), Clinical Global Impression-Severity (CGI-S), 5-level version of European Quality of Life Questionnaire 5-Dimensional Classification (EQ-5D-5L), and Sheehan Disability Scale (SDS) at baseline, and at the 1-, 4-, and 12-week. RESULTS: From baseline to week 12, neurofeedback training reduced mean scores on HAM-D, BDI-II, CGI-S, and SDS, and increased mean EQ-5D-5L tariff score. In the neurofeedback augmentation group, the response and remission rates were 58.3% and 50.0%, respectively, at week 12. Changes in HAM-D, EQ-5D-5L tariff score, and SDS were significantly larger in the neurofeedback group than in the medication-only (TAU) group. No significant difference in BDNF level was found pre- vs. post-treatment in any of the groups. CONCLUSION: Despite the small sample size, these results suggest that neurofeedback treatment may be effective as an augmentation treatment, not only for depressive symptoms, but also for functional recovery, in patients with TRD.

ABSTRACT

There is considerable overlap in the clinical presentations of apathy and depression. However, differential diagnosis between apathy and other psychiatric conditions, including depression and dementia, is important. In this report, we present the case of a 67-year-old woman with a history of receiving selective serotonin reuptake inhibitor (SSRI) treatment for depression. Differential diagnosis between treatment-resistant depression and SSRI-induced apathy syndrome was required. The symptoms of her apathy syndrome were relieved after the discontinuation of SSRIs and the addition of olanzapine, methylphenidate, and modafinil. Furthermore, we briefly review related literature in this article.

ABSTRACT

PURPOSE: This study investigated the effectiveness of meaning-centered psychotherapy (MCP), which is known to be a helpful psychotherapeutic intervention in distressing conditions, for patients with pancreatobiliary cancer. MATERIALS AND METHODS: We recruited 37 patients with pancreatobiliary cancer from three university general hospitals and assessed their psychological characteristics. Patients who reported clinically significant emotional distress were recommended to undergo MCP. Patients who consented to MCP were provided four sessions of the therapy. Patient psychological characteristics were assessed again 2 months after MCP. For statistical comparison, outcome variables included anxiety, depression, mental adjustment to cancer, and quality of life (QoL), as well as the degree of stress and physical symptoms. RESULTS: Sixteen patients completed the MCP and the final assessment 2 months later. In the initial assessment, the patients receiving MCP showed higher levels of anxiety and depression than those not receiving MCP, and QoL was also lower in terms of role function, emotional function, social function, and global QoL. At the 2-month follow-up, the MCP group showed a significant improvement in anxiety (p=0.007), depression (p=0.010), and anxious preoccupation (p < 0.001). In addition, QoL significantly improved in the MCP group, while there was no significant change in the non-MCP group. CONCLUSION: In this study, MCP showed potential therapeutic benefits against emotional distress in patients with pancreatobiliary cancer, improving their QoL.

ABSTRACT

OBJECTIVES: The purpose of this study was to examine effects of adjunctive aripiprazole versus bupropion, on depressive symptoms of female depression.METHODS: Sixty six female patients with major depressive disorders were enrolled from a six-week, randomized prospective open-label multi-center study. Participants were randomized to receive aripiprazole (2.5–10 mg/day) or bupropion (150–300 mg/day). Montgomery Asberg Depression Rating Scale, 17-item Hamilton Depression Rating scale (HAM-D17), Iowa Fatigue Scale, Drug-Induced Extrapyramidal Symptoms Scale, Psychotropic-Related Sexual Dysfunction Questionnaire scores, and Clinical Global Impression-Severity (CGI-S) were obtained at baseline and after one, two, four, and six weeks. Changes on individual items of HAM-D17 were assessed as well as on composite scales (anxiety, insomnia and drive), and on four core subscales that capture core depression symptoms.RESULTS: Overall, both treatments improved depressive symptoms, without causing serious adverse events. There were significant differences in the HAM-D17 total score (p=0.046) and CGI-S (p=0.004), between aripiprazole and bupropion augmentation, favoring aripiprazole over bupropion. Aripiprazole revealed significantly greater effect size in depressed mood (p=0.006), retardation (p=0.005), anxiety psychic (p=0.032), and general somatic symptom (p=0.01).CONCLUSION: While both treatments were effective, results of this study suggested that aripiprazole may be preferable, in treating general and core symptoms of female depression.

ABSTRACT

OBJECTIVE: Physical or mental imbalance caused by harmful stimuli can induce stress to maintain homeostasis. During chronic stress, the sympathetic nervous system is hyperactivated, causing physical, psychological, and behavioral abnormalities. At present, there is no accepted standard for stress evaluation. This review aimed to survey studies providing a rationale for selecting heart rate variability (HRV) as a psychological stress indicator. METHODS: Term searches in the Web of Science®, National Library of Medicine (PubMed), and Google Scholar databases yielded 37 publications meeting our criteria. The inclusion criteria were involvement of human participants, HRV as an objective psychological stress measure, and measured HRV reactivity. RESULTS: In most studies, HRV variables changed in response to stress induced by various methods. The most frequently reported factor associated with variation in HRV variables was low parasympathetic activity, which is characterized by a decrease in the high-frequency band and an increase in the low-frequency band. Neuroimaging studies suggested that HRV may be linked to cortical regions (e.g., the ventromedial prefrontal cortex) that are involved in stressful situation appraisal. CONCLUSION: In conclusion, the current neurobiological evidence suggests that HRV is impacted by stress and supports its use for the objective assessment of psychological health and stress.

ABSTRACT

We aimed to examine the potential relationship between season of birth (SOB) and clinical characteristics in Korean patients with unipolar non-psychotic major depressive disorder (MDD). Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, 891 MDD patients were divided into two groups, those born in spring/summer (n=457) and those born in autumn/winter (n=434). Measurement tools comprising the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Scale for Suicidal Ideation, Clinical Global Impression of severity, Social and Occupation Functional Assessment Scale, WHO Quality of Life assessment instrument-abbreviated version, Alcohol Use Disorder Identification Test, and Temperament and Character Inventory were used to evaluate depression, anxiety, overall symptoms, suicidal ideation, global severity, social function, quality of life, drinking, and temperament and character, respectively. Using independent t-tests for continuous variables and χ2 tests for discrete variables, the clinical characteristics of the two groups were compared. MDD patients born in spring/summer were on average younger at onset of first depressive episode (t=2.084, p=0.038), had greater loss of concentration (χ2=4.589, p=0.032), and were more self-directed (t=2.256, p=0.025) than those born in autumn/winter. Clinically, there was a trend for the MDD patients born in spring/summer to display the contradictory characteristics of more severe clinical course and less illness burden; this may have been partly due to a paradoxical effect of the 5-HT system.

ABSTRACT

Our study aimed to establish the relationship between the number of depressive symptoms and the clinical characteristics of major depressive disorder (MDD). This would enable us to predict the clinical significance of the number of depressive symptoms in MDD patients. Using data from the Clinical Research Center for Depression (CRESCEND) study in Korea, 853 patients with DSM-IV MDD were recruited. The baseline and clinical characteristics of groups with different numbers of depressive symptoms were compared using the χ2 test for discrete variables and covariance (ANCOVA) for continuous variables. In addition, the scores of these groups on the measurement tools were compared by ANCOVA after adjusting the potential effects of confounding variables. After adjusting the effects of monthly income and history of depression, a larger number of depressive symptoms indicated higher overall severity of depression (F [4, 756] = 21.458, P < 0.001) and higher levels of depressive symptoms (F [4, 767] = 19.145, P < 0.001), anxiety symptoms (F [4, 765] = 12.890, P < 0.001) and suicidal ideation (F [4, 653] = 6.970, P < 0.001). It also indicated lower levels of social function (F [4, 760] = 13.343, P < 0.001), and quality of life (F [4, 656] = 11.975, P < 0.001). However, there were no significant differences in alcohol consumption (F [4, 656] = 11.975, P < 0.001). The number of depressive symptoms can be used as an index of greater illness burden in clinical psychiatry.

ABSTRACT

The purpose of this study was to explore the relationship between cerebral amyloid deposition and overall clinical factors including cognitive functions in geriatric depression by using 18F-florbetaben positron emission tomography. Thirteen subjects aged over 60 years who had a history of major depressive disorder and also had subjective memory complaint were included. Of all subjects, 3 subjects judged as amyloid positive, and the others judged as amyloid negative. Their memory, visuospatial functions and attention abilities were negatively correlated with amyloid deposition in specific brain regions, but their language and recognition abilities were not correlated with any region. The amyloid deposition of the whole brain region was significantly negatively correlated with immediate memory.

ABSTRACT

OBJECTIVE: We investigated the efficacy and tolerability of paliperidone extended-release (ER) tablets in patients with first-episode psychosis (n=75). METHODS: This was an 8-week, open-label, multicenter trial. The primary outcome variable was scores on the Positive and Negative Syndrome Scale (PANSS); secondary measures included the Scale for the Assessment of Negative Symptoms (SANS), the Cognitive Assessment Interview (CAI), and the Global Assessment of Functioning (GAF). To assess safety, we measured drug-related adverse events, weight, lipid-related variables, and prolactin and administered the Simpson–Angus Rating Scale (SARS), the Abnormal Involuntary Movement Scale (AIMS), the Barnes Akathisia Scale (BAS), the Arizona Sexual Experiences Scale (ASEX), and the Udvalg for Kliniske Undersogelser side effect rating scale (UKU). RESULTS: The administration of paliperidone ER resulted in significant improvement in the PANSS, SANS, CAI, and GAF scores (p<0.001) over time. This improvement was evident as early as 1 week. The most frequent adverse events were akathisia, somnolence, anxiety, and sedation, which were well tolerated. Modest increases in weight and lipid profiles were also noted. Prolactin levels were substantially increased at the endpoint in both male and female patients. CONCLUSION: These results indicate that paliperidone ER is effective and is characterized by good tolerability in the treatment of positive and negative symptoms and cognitive functioning in first-episode psychosis.

ABSTRACT

OBJECTIVE: The purpose of this study was to compare duloxetine monotherapy to combination therapy with other antidepressants in patients with major depressive disorder in a clinical, real world setting. METHODS: An eight-week, retrospective, multi-center study of outpatients with major depressive disorder was undertaken. After screening 415 patients, enrolled in this study from July 2009 to June 2014 were 82 patients from among three centers who had been taking duloxetine with or without other antidepressant and not administered with atypical antipsychotics. We compared the mean changes of the Clinical Global Impression-Severity Scale (CGI-S) as a primary measure and the discontinuation rate as a secondary measure between the duloxetine monotherapy group (n=36, 43.9%) and the combination therapy with other antidepressants group (n=46, 56.1%) at baseline, one, two, four and eight weeks. RESULTS: There were no significant differences across the demographic characteristics between two groups. There was, however, a statistically greater improvement on the CGI-S at weeks 2, 4 and 8 in the combination group compared with the monotherapy group. There were no significant differences in discontinuation rate and adverse events between two groups. No serious adverse events were reported in both groups during the study period. CONCLUSION: This result suggests that the duloxetine combination therapy with other antidepressants could improve effectiveness and have comparable tolerability with the monotherapy in the treatment of outpatients with major depressive disorders in a naturalistic setting. Adequately powered, well-controlled clinical trials are strongly warranted to confirm our findings due to methodological shortcomings.

ABSTRACT

OBJECTIVES: The aim of this study is to develop guideline for use in diagnosis of depression. METHODS: Development of this guideline was processed according to the ADAPTE manual, which was developed for adaptation of good clinical practice guidelines. Important key questions were determined, and a systematic review of clinical practice guidelines was performed. The contents of guidelines selected by comparison of the methodological quality and currency were evaluated with regard to the applicability and acceptability. Answers to key questions and clinical recommendations were established by peer review. RESULTS: There has been no evidence on strategies to improve the accuracy and rate of diagnosis of depression. The screening tools for depression were useful in diagnosis of depression in clinical practice. CONCLUSION: The results of this study may suggest the necessity of strategies to improve the validity and reliability of diagnosis of depression. In contrast, scales for screening depression can be useful in diagnosis of depression. This guideline did not include systematic reviews regarding useful scales for diagnosis of depression. In the future, amendment of this guideline might be needed in order to supplement limitations.

Important key questions were determined, and a systematic review of clinical practice guidelines was performed. The contents of guidelines selected by comparison of the methodological quality and currency were evaluated with regard to the applicability and acceptability. Answers to key questions and clinical recommendations were established by peer review. RESULTS: Careful evaluations on the characteristics of depression, including subtype, severity, suicidality, and psychiatric and physical comorbidities were recommended because these factors can have an influence on course and prognosis in treatment of depression. CONCLUSION: The results of this study may contribute to the systematic evaluation of depression, based on clinical importance. However, this guideline did not include systematic reviews regarding useful scales for evaluation of depression. In the future, amendment of this guideline might be needed in order to supplement limitations.

ABSTRACT

OBJECTIVES: The aim of this study is to evaluate the association between rs6280 and rs905568 genetic polymorphism of DRD3 gene and the treatment response of amisulpride. METHODS: After six weeks treatment of amisulpride, 125 schizophrenia patients were interviewed based on the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression-Severity (CGI-S). The genotyping for rs6280 and rs905568 was performed using TaqMan single nucleotide polymorphism (SNP) genotyping assay. RESULTS: There was no significant difference in the frequency of genotype and allele of rs6280 between the responders and non-responders based on the total, positive, and general score of PANSS and CGI-S score. However, there was a significant association between this SNP and treatment response in the negative score of PANSS (chi2 = 5.23, p = 0.022). There was no significant association between rs905568 and the response in positive, negative, general, and total PANSS score and CGI-S score. CONCLUSIONS: This is the first positive association study between DRD3 gene and the treatment response of negative symptoms to amisulpride in Korean schizophrenia patients. A larger scale research on more SNP of the DRD3 gene will make a progress in the study of pharmacogenetics on the treatment response of the amisulpride.
