ABSTRACT
BACKGROUND: We conducted a one-year, retrospective, mirror-image study to investigate the clinical effectiveness and safety of aripiprazole once monthly (AOM) in patients with bipolar disorder (BD). We compared pre-treatment conditions with outcomes after 12 months of AOM treatment. METHODS: Seventy-five bipolar patients were recruited from 12 hospitals in Korea. We included 75 patients with BD who had received at least three AOM treatments from September 2019 to September 2022 and had accessible electronic medical record (EMRs) for the year before and after the baseline visit. RESULTS: The overall number of mood episodes significantly decreased from a mean of 1.5 ± 1.2 episodes pre-AOM to 0.5 ± 1.2 episodes post-AOM. Manic episodes significantly decreased from 0.8 ± 0.8 episodes pre-AOM to 0.2 ± 0.5 episodes post-AOM, and depressive episodes significantly decreased from 0.5 ± 0.8 episodes pre-AOM to 0.2 ± 0.6 episodes post-AOM (p = 0.017). Moreover, the number of psychiatric medications and pills and the proportion of patients treated with complex polypharmacy were significantly decreased post-AOM. LIMITATIONS: The small sample size was insufficient to fully represent the entire population of individuals with BD, and potential selection bias was introduced due to only including subjects who received AOM three or more times. CONCLUSION: The results of this study suggest that AOM can reduce mood episode relapse and may be clinically beneficial in the treatment of BD patients, potentially reducing issues associated with polypharmacy in some individuals.

This study examined factors related to high fear of coronavirus disease 2019 (COVID-19) infection in healthcare workers (HCWs) in COVID-19 dedicated teams. We assigned 371 HCWs to low, medium, and high COVID-19 infection fear groups, and investigated factors associated with COVID-19 infection fear. High COVID-19 infection fear was significantly associated with being a woman and poor professional quality of life. High COVID-19 infection fear group had higher burnout levels and secondary traumatic stress scores than the low and medium fear groups. These findings deepen our understanding of risk factors for and psychological outcomes of COVID-19 infection fear in HCWs.

This study aims to explore the impact of distributional changes in coronavirus disease 2019 (COVID-19) infection fear with sex differences. A quota sampling strategy was followed and 483 Korean adults were surveyed in a community sample. Self-report questionnaires were used to assess COVID-19 infection fear, depressive symptoms, and general characteristics. Quantile regression was used to explore the regression relationship of COVID-19 infection fear and an individual's sex. There was a significant difference in COVID-19 infection fear (P = 0.001) and depression (P = 0.008) between the sexes - male and female. The differences between sexes at the 20th and 30th percentiles were significant (ß = 2.04, P = 0.006; ß = 1.5, P = 0.004, respectively). The results demonstrate that sex significantly predicts COVID-19 infection fear and women had significantly greater fear than men in the mild-level of COVID-19 infection fear.

The objective of this study was to compare recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2022 (KMAP-BP 2022) with other recently published guidelines for treating bipolar disorder. We reviewed a total of six recently published global treatment guidelines and compared treatment recommendation of the KMAP-BP 2022 with those of other guidelines. For initial treatment of mania, there were no significant differences across treatment guidelines. All guidelines recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or a combination of an MS with an AAP as a first-line treatment strategy in a same degree for mania. However, the KMAP-BP 2022 recommended MS + AAP combination therapy for psychotic mania, mixed mania and psychotic depression as treatment of choice. Aripiprazole, quetiapine and olanzapine were the first-line AAPs for nearly all phases of bipolar disorder across guidelines. Some guideline suggested olanzapine is a second-line options during maintenance treatment, related to concern about long-term tolerability. Most guidelines advocated newer AAPs (asenapine, cariprazine, long-acting injectable risperidone, and aripiprazole once monthly) as first-line treatment options for all phases while lamotrigine was recommended for depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. KMAP-BP 2022 guidelines were similar to other guidelines, reflecting current changes in prescription patterns for bipolar disorder based on accumulated research data. Strong preference for combination therapy was characteristic of KMAP-BP 2022, predominantly in the treatment of psychotic mania, mixed mania and psychotic depression.
ABSTRACT
Objective: The Functioning Assessment Short Test (FAST) is a relatively specific test for bipolar disorders designed to assess the main functioning problems experienced by patients. This brief instrument includes 24 items assessing impairment or disability in 6 domains of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time. It has already been translated into standardized versions in several languages. The aim of this study is to measure the validity and reliability of the Korean version of FAST (K-FAST). Methods: A total of 209 bipolar disorder patients were recruited from 14 centers in Korea. K-FAST, Young Mania Rating Scale (YMRS), Bipolar Depression Rating Scale (BDRS), Global Assessment of Functioning (GAF) and the World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF) were administered, and psychometric analysis of the K-FAST was conducted. Results: The internal consistency (Cronbach's alpha) of the K-FAST was 0.95. Test-retest reliability analysis showed a strong correlation between the two measures assessed at a 1-week interval (ICC = 0.97; p < 0.001). The K-FAST exhibited significant correlations with GAF (r = -0.771), WHOQOL-BREF (r = -0.326), YMRS (r = 0.509) and BDRS (r = 0.598). A strong negative correlation with GAF pointed to a reasonable degree of concurrent validity. Although the exploratory factor analysis showed four factors, the confirmatory factor analysis of questionnaires had a good fit for a six factors model (CFI = 0.925; TLI = 0.912; RMSEA = 0.078). Conclusion: The K-FAST has good psychometric properties, good internal consistency, and can be applicable and acceptable to the Korean context.
ABSTRACT
OBJECTIVE: We aimed to determine the effects of depression, COVID-19 infection fear, and resilience on COVID-19-related functional impairment. METHODS: We obtained data from 476 community-dwelling adults aged 20-69 years living in Jeju, South Korea, and evaluated the relationships between COVID-19-related functional impairment (work/school, social, and home life) and sociodemographic and healthrelated characteristics, COVID-19-related life changes (financial difficulties since the pandemic, employment change, interpersonal conflict), and clinical characteristics, including depression, COVID-19 infection fear, and resilience. RESULTS: Functional impairment in the home life domain was associated with marital status and monthly income. Greater work/school, social, and home life functional impairment was significantly associated with all COVID-19-related life changes. Regression analysis indicated that resilience modulated the positive associations of COVID-19-related functional impairment with symptoms of depression and COVID-19 infection fear when relevant factors were controlled for. CONCLUSION: Our results suggest the importance of clinical characteristics, including depression, COVID-19 infection fear, and resilience for understanding functional impairment related to COVID-19. These results have important implications for interventions aimed at reducing depression and COVID-19 infection fear, and enhancing resilience.
ABSTRACT
Objective: We revised the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP), first published in 2002 and revised in 2006, 2010, 2014, and 2018, to reflect recent progress in the treatment of bipolar disorder. Methods: The questionnaires consisted of 56 items for adult patients and 7 items for child/adolescent patients, and were used to obtain the consensus of experts regarding pharmacological treatment strategies for various phases of bipolar disorder. The review committee included 87 Korean psychiatrists and 40 child and adolescent psychiatry experts. Results: For treatment of manic episodes, a combination of a mood stabilizer (MS) and atypical antipsychotics (AAP), or monotherapy with MS or AAP were recommended as first-line treatments. Combinations of MS and AAP, or AAP and lamotrigine (LMT) were recommended as first-line treatments for depressive episodes regardless of the severity. Monotherapy with MS, AAP, or LMT were also first-line treatments for mild to moderate depressive episodes. For mixed features, a combination of MS and AAP, or monotherapy with AAP or MS were recommended as first-line treatments, and a combination of AAP and LMT, or MS and LMT were the first-line treatments for depressive mixed state. Conclusion: The recommendations of the KMAP-BP 2022 have changed from the previous version, to reflect the evolution of the social culture and healthcare system in Korea and recent evidence regarding pharmacotherapy of bipolar disorder. The KMAP-BP 2022 provides clinicians with a wealth of information regarding appropriate strategies to treat patients with bipolar disorder.
ABSTRACT
OBJECTIVE: The purpose of this study was to explore the accuracy of expectation of medical lethality and to identify characteristics related to high medical lethality in suicide attempters. METHODS: A total of 370 suicide attempters (173 men, 197 women) who visited the emergency department at one university hospital were interviewed. RESULTS: Using the Lethality Scale, 103 (27.8%), 114 (30.8%), and 153 (41.4%) suicide attempters were assigned to the low, medium, and high medical lethality groups, respectively. The medium and high medical lethality groups were older, and reported poorer socioenvironmental conditions, compared with the low lethality group. Higher levels of suicide intent were associated with more lethal attempts but only for those attempters who had accurate expectations of the medical lethality of their attempts. CONCLUSION: The accuracy of expectations about the likelihood of dying was found to moderate the relationships between suicide intent and medical lethality.
ABSTRACT
Maternal adverse childhood experiences (ACEs) may negatively affect the mental health and development of their offspring. The purpose of this study was to investigate the association of maternal ACE and offspring's psychiatric disorder and the mediating effect of maternal depression. The subjects included 463 mothers (42.78 ± 5.68 years) and their offspring aged 6-18 years (13.26 ± 3.90 years). Mothers reported their ACE before age 18 and completed the Beck Depression Inventory-II and Diagnostic Predictive Scales (DPS), a screening tool for offspring's psychiatric disorder. 35.42% of subjects had at least one ACE, and 11.0% reported three or more ACEs. Higher maternal ACE scores were associated with a significantly higher prevalence of offspring's psychiatric disorders (p < 0.001). Household dysfunction of maternal ACE (OR = 2.263, p < 0.001) is significantly associated with offspring's psychiatric disorder. In the mediation model in which the household dysfunction affects the number of offspring's psychiatric disorders, the partial mediation model through maternal depression was significant. The mother's experience of household dysfunction before the age of 18 has a significant impact on her offspring's psychiatric disorder and supported significant mediation through maternal depression. Further research is needed to determine the mechanisms of intergenerational transmission of ACE and offspring's psychopathology.

OBJECTIVE: Adverse childhood experiences (ACEs) are associated with negative physical and mental health outcomes across the lifespan, but research on intergenerational transmission of maternal ACEs and its impact on the offspring's mental health problems are limited. The study examines the effects of maternal ACEs on the risk of internalizing or externalizing problems among offspring. METHODS: There were 450 mother-child dyads. Mothers completed the Adverse Childhood Experiences Questionnaire. The child outcomes included internalizing and externalizing problems assessed by the Korean Child Behavior Checklist (K-CBCL) and Korean Youth Self-Report (K-YSR), depression assessed by the Center for Epidemiological Studies Depression Scale for Children (CES-DC) and anxiety assessed by the Screen for Child Anxiety Related Emotional Disorders (SCARED). RESULTS: 36.1% of mothers experienced at least one ACE, and 11.1% experienced three or more ACEs. Cumulative maternal ACEs were associated with internalizing problems, externalizing problems, depression and anxiety in the offspring. Household dysfunction from maternal ACEs was significantly associated with delinquent behavior, anxiety/depression, and somatic complaints in the offspring. CONCLUSION: The findings support the hypothesis that maternal ACEs are related to mental health problems in the offspring. Further research is needed to determine the factors mediating intergenerational transmission as well as intervention strategies to prevent ACEs and mental health problems in the offspring.
ABSTRACT
OBJECTIVE: The relationship among physical functional decline, low-grade inflammation, and depression remains unclear. The aim of this study was to examine the association between hand grip strength (HGS) and high-sensitivity C-reactive protein (hs-CRP) in a large sample with depression. METHODS: This study used data obtained from a representative Korean sample of 9,402 people who participated in the seventh Korean National Health and Nutrition Examination Survey. Physical function was assessed using a digital grip strength dynamometer. Depression was identified using a cutoff of 5 on the Patient Health Questionnaire-9 (PHQ-9), and high hs-CPR level was defined as ≥ 3.0 mg/L. RESULTS: In older adults (≥ 60 years) with depression, 43.8% of those with high hs-CRP levels had low HGS, compared to 21.8% of those with hs-CRP levels < 3.0 mg/L (p = 0.002). Multivariate analysis revealed that, after adjustments for potentially confounding factors, high hs-CRP was independently associated with lower HGS (B = -2.25; 95% confidence interval = -4.49 to -0.02) in older adults with depression, but not in younger or middle-aged adults with depression. CONCLUSION: These findings suggest a significant correlation between physical functional decline and low-grade inflammation in older adults with depression.
ABSTRACT
OBJECTIVE: We explored factors associated with health-related quality of life (HRQOL), including socio-demographic and clinical characteristics, in among older people exposed to the Jeju 4·3 incident, and aimed to determine the effects of depression, posttraumatic stress disorder (PTSD) and perceived social support on HRQOL. METHODS: We obtained data from 110 survivors and 1,011 immediate family members of the victims of the Jeju April 3 incident (mean age, 75.1 years), and evaluated the relationships of HRQOL with sociodemographic and clinical characteristics including posttraumatic and depressive symptoms, and perceived social support. RESULTS: Poorer physical health, psychological health, social relationships, and environment HRQOL domain scores were strongly associated with older age, being a woman, poor socioeconomic status, and symptoms of depression and PTSD. The regression analyses indicated that, when relevant factors were controlled for, perceived social support moderated the negative association between HRQOL and psychiatric symptoms. CONCLUSION: Our results suggest the importance of sociodemographic characteristics, in addition to psychiatric symptoms, for understanding HRQOL in older people exposed to the Jeju 4·3 incident. These results have important implications for interventions aiming to improve the HRQOL of the victims of the Jeju 4·3 incident.
ABSTRACT
The purpose of this study was to identify characteristics related to high resilience among older people exposed to the Jeju 4·3 incident. A total of 1,121 aged adults were assigned to low, medium, and high resilience groups, and factors associated with low and high resilience were investigated. High resilience was significantly associated with a low prevalence of depression and high levels of life satisfaction and psychosocial support, as well as with younger age, being a man, higher education level, and current employment. The results deepen our understanding of resilience in the aged people who experienced the early life trauma.

OBJECTIVES: Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study inves-tigated the impact of maternal ACEs on PTSD in the offspring. METHODS: A total of 156 mothers with children aged 13-18 years completed the Diagnostic Interview Schedule for Children (DISC) Predictive Scales to determine the presence of psychiatric disorders in their offspring. The subjects completed the ACE questionnaire and the Early Trauma Inventory Self-Report-Short Form. Multivariable logistic regression was used to analyze the relationship between ma-ternal ACEs and PTSD in the offspring. RESULTS: Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). CONCLUSION: Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.
ABSTRACT
BACKGROUND: In many high-income Western countries, the prevalence of dementia had been reduced over the past decades. OBJECTIVE: We investigated whether the prevalence of all-cause dementia, Alzheimer's disease, vascular dementia, and mild cognitive impairment (MCI) had changed in Korea from 2008 to 2017. METHODS: Nationwide Survey on Dementia Epidemiology of Korea (NaSDEK) in 2008 and 2017 was conducted on representative elderly populations that were randomly sampled across South Korea. Both surveys employed a two-stage design (screening and diagnostic phases) and diagnosed dementia and MCI according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders and the consensus criteria from the International Working Group, respectively. The numbers of participants aged 65 years or older in the screening and diagnostic phases were 6,141 and 1,673 in the NaSDEK 2008 and 2,972 and 474 in the NaSDEK 2017, respectively. RESULTS: The age- and sex-standardized prevalence of all-cause dementia and Alzheimer's disease showed nonsignificant decrease (12.3% to 9.8%, odds ratio [OR] = 0.89, 95% confidence interval [CI] = 0.54-1.48 for all-cause dementia; 7.6% to 6.8%, OR [95% CI] = 0.91 [0.58-1.42] for Alzheimer's disease). Vascular dementia decreased in the young-old population aged less than 75 years (2.7% to 0.001%, OR [95% CI] = 0.04 [0.01-0.15]) and in women (1.9% to 0.5%, OR [95% CI] = 0.27 [0.10-0.72]) while MCI remained stable (25.3% to 26.2%, OR [95% CI] = 1.08 [0.67-1.73]). CONCLUSION: We found that the prevalence of dementia in Korea showed a nonsignificant decrease between 2008 and 2017.

Visual disabilities in central nervous system autoimmune diseases such as multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), are important symptoms. Past studies have focused on neuro-inflammatory changes and demyelination in the white matter of the brain and spinal cord. In MS, neuro-inflammatory lesions have been diagnosed in the visual pathway; the lesions may perturb visual function. Similarly, neuropathological changes in the retina and optic nerves have been found in animals with chronic EAE. Although the retina and optic nerves are immunologically privileged sites via the blood-retina barrier and blood-brain barrier, respectively, inflammation can occur via other routes, such as the uvea (e.g., iris and choroid) and cerebrospinal fluid in the meninges. This review primarily addresses the direct involvement of the blood-retina barrier and the blood-brain barrier in the development of retinitis and optic neuritis in EAE models. Additional routes, including pro-inflammatory mediator-filled choroidal and subarachnoid spaces, are also discussed with respect to their roles in EAE-induced visual disability and as analogues of MS in humans.

BACKGROUND: The psychological consequences of the Jeju April 3 incident, which occurred almost 70 years ago, may be long-lasting. Thus, the present study investigated the prevalence and impact of comorbid post-traumatic stress disorder (PTSD) and depression among older people exposed to this incident. METHODS: A total of 110 survivors and 1,011 immediate family members of the victims of the Jeju April 3 incident completed a questionnaire that collected demographic information, the Center for Epidemiologic Studies Depression Scale (CES-D), and the PTSD Checklist-Civilian Version (PCL-C). Comorbidity was defined as a combination of CES-D positivity and PCL-C positivity. To identify trends among clinical characteristics according to the severity of the comorbid PTSD and depression condition, linear-by-linear association tests were conducted. RESULTS: Of the 1,121 older people included in the present study, 10.8% met the criteria for comorbid PTSD and depression, 3.0% had PTSD only, and 24.3% had depression only. Additionally, as the severity of the comorbid condition increased, there were trends for lower levels of socioeconomic status and perceived family support and higher suicidality. Compared to either disorder alone, individuals with the comorbid condition were 2.04 times more likely to have a higher suicidal risk. LIMITATIONS: Standardized diagnostic tools for assessing the case findings were not employed in the present study. CONCLUSION: Comorbid PTSD and depression was prevalent among older people exposed to the Jeju April 3 incident. Additionally, this comorbid condition was related to a serious clinical phenomenology, including a higher suicidal risk.

BACKGROUND: Apolipoprotein E (APOE) É4 allele carriers have an increased risk of late-onset Alzheimer's disease (AD). However, in the "Choosing Wisely" campaign for avoiding unnecessary medical tests, treatments, and procedures, APOE genetic testing is not recommended as a predictive test for AD. OBJECTIVE: The aim of this study was to investigate the potential value of APOE genetic testing in a specific clinical context. METHODS: Subjects with poor performance in the Korean version of the Mini-Mental Status Examination for dementia screening (MMSE-DS) with a Z-score of less than -1.5 were recruited from the public health centers. All participants underwent APOE genetic testing. Family history of dementia (FHx) was confirmed if one or more first-degree relatives had dementia. RESULTS: Among 349 subjects, 162 (46.4%) were diagnosed with AD. APOEÉ4 allele carriers had a much higher risk of AD in the group with FHx than in the group without FHx (ORâ=â15.81, 95% CIâ=â2.74-91.21 versus ORâ=â1.82, 95% CIâ=â1.00-3.27, zâ=â2.293, pâ=â0.011). The sensitivity, specificity, positive predictive value, and negative predictive value for the APOEÉ4 allele were 47.7%, 90.9%, 91.3%, and 46.5% in the group with FHx. CONCLUSION: It would be a wise choice to perform the APOE genetic testing for the diagnosis of AD in subjects with poor performance in a screening test and a family history of dementia.

OBJECTIVE: In this study we investigated whether current mood states of patients with bipolar disorder have an influence on the screening accuracy of the Mood Disorder Questionnaire (MDQ). METHODS: A total of 452 patients with mood disorder (including 192 with major depressive disorder and 260 with bipolar disorder completed the Korean version of the MDQ. Patients with bipolar disorder were subdivided into three groups (bipolar depressed only, bipolar euthymic only, bipolar manic/hypomanic only) according to current mood states. The screening accuracy of the MDQ including sensitivity, specificity and area under the curve (AUC) of receiver operating characteristic (ROC) curves were evaluated according to current mood states. RESULTS: The optimal cutoff of MDQ was 5 in this study sample. Sensitivity and specificity were not significantly different according to current mood states. Significant differences in AUCs of four independent ROC curves were not found (ROC 1st curve included all bipolar patients; ROC 2nd curve included only bipolar depressed patients; ROC 3rd curve included only bipolar manic/hypomanic patients; ROC 4th curve included only bipolar euthymic patients). CONCLUSION: The study results showed that current mood states (either euthymic state, depressed or manic/hypomanic) did not significantly influence the screening accuracy of the MDQ suggesting that the MDQ could be a useful screening instrument for detecting bipolar disorder in clinical practice regardless of the current mood symptoms of subjects.
