1. An exploratory study on spatiotemporal clustering of suicide in Korean adolescents

Author: Won-Seok Choi, Beop-Rae Roh, Duk-In Jon, Vin Ryu, Yunhye Oh, and Hyun Ju Hong
Subjects: Adolescent, Suicide, Suicide cluster, Space–time, Density-based clustering, Korea, Pediatrics, RJ1-570, Psychiatry, RC435-571
Abstract: Abstract Background Adolescent suicides are more likely to form clusters than those of other age groups. However, the definition of a cluster in the space–time dimension has not been established, neither are the factors contributing to it well known. Therefore, this study aimed to identify space–time clusters in adolescent suicides in Korea and to examine the differences between clustered and non-clustered cases using novel statistical methods. Methods From 2016 to 2020, the dates and locations, including specific addresses from which the latitude and longitude of all student suicides (aged 9–18 years) in Korea were obtained through student suicide reports. Sociodemographic characteristics of the adolescents who died by suicide were collected, and the individual characteristics of each student who died by suicide were reported by teachers using the Strengths and Difficulties Questionnaire (SDQ). Density-Based Spatial Clustering of Applications with Noise (DBSCAN) analysis was used to assess the clustering of suicides. Results We identified 23 clusters through the data analysis of 652 adolescent suicides using DBSCAN. By comparing the size of each cluster, we identified 63 (9.7%) spatiotemporally clustered suicides among adolescents, and the temporal range of these clusters was 7–59 days. The suicide cluster group had a lower economic status than the non-clustered group. There were no significant differences in other characteristics between the two groups. Conclusion This study has defined the space–time cluster of suicides using a novel statistical method. Our findings suggest that when an adolescent suicide occurs, close monitoring and intervention for approximately 2 months are needed to prevent subsequent suicides. Future research using DBSCAN needs to involve a larger sample of adolescents from various countries to further corroborate these findings.

2. Suicide warning signs that are challenging to recognize: a psychological autopsy study of Korean adolescents

Author: Yeon Jung Lee, Yong-Sil Kweon, Yun Hyong Kang, Kyung Hee Yoon, Mi-Sun Lee, Soo-Young Bhang, and Hyun Ju Hong
Subjects: Suicide, Adolescent, Autopsy, Pediatrics, RJ1-570, Psychiatry, RC435-571
Abstract: Abstract Background In South Korea, the leading cause of youth death has been suicide for about 20 years. In this study, we conducted a multi-method psychological autopsy to identify the psychiatric diagnosis, developmental history, personality traits, family history, school life, warning signs of suicide, and risk factors related to suicide for the first time in Korea. Methods This was a postmortem, retrospective, and descriptive study of 36 adolescents who died by suicide between August 2015 and July 2021 in South Korea. We obtained qualitative and quantitative data from the Korean Psychological Autopsy of Adolescent, conducted by the Suicide and School Mental Health Institute, the official student mental health policy-focused research institute of the Korean Ministry of Education. Results The adolescents comprised equal percentage of girls and boys. Approximately half of the deaths (55.6%) occurred at home and most (72.2%) involved jumping from a height. Most of the adolescents (97.2%) had one major psychiatric disorder before death, with depressive disorder being the most prevalent (75%). They were at a high risk for internet addiction before death. The most common personality trait was avoidance (28.6%), followed by submissiveness (27.3%). Half of the parents reported that the adolescents were satisfied with their school life and the teachers observed that they had no behavioral problems. One year before death, seven (19.4%) adolescents injured themselves and five (13.9%) had attempted suicide. Most of the deceased (80.6%) had expressed suicide warning signs to their families within one year before death. Adolescents had a long experience of family-related adverse events. Conclusions Most of the adolescents had mental health disorders and expressed suicidal intentions using verbal and nonverbal signs. However, it was challenging for families to recognize the risk signs because of adolescents’ personality traits or a good school life. To prevent adolescent suicide, adolescents, parents, and teachers need to be educated to recognize signs of suicide warning signs and equipped to guide adolescents to appropriate care.

3. Korean adolescent suicide and search volume for 'self-injury' on internet search engines

Author: Jin Yeong Son, Jun Hee Han, Seung Chan Kim, Won-Seok Choi, and Hyun Ju Hong
Subjects: adolescent, suicide, internet search, self-injury, sex difference, suicidal attempt, Psychiatry, RC435-571
Abstract: IntroductionMany adolescents with suicidal ideation receive support through the Internet. However, they also find ways to attempt suicide or strengthen their suicidal ideation through this medium. This study analyzed the association between the search volume of suicide-related terms and the number of suicides among Korean adolescents. We also analyzed the correlations between the search volumes of suicide-related terms.MethodsWe selected seven words (suicide, self-injury, depression, academic score, school violence, outcasts, and family trouble) related to adolescent suicide. A dataset was constructed by combining data from the most commonly used search engine in Korea (Naver Datalab) and the daily number of adolescent suicides in school settings (n = 347) from January 1, 2016 to December 31, 2018, collected from the Ministry of Education. Poisson regression and Pearson correlation analyses were performed.ResultsSignificant associations were found between suicide attempts and search term volumes, which differed according to sex and time interval. Among the search terms, “self-injury” was most strongly associated with suicide, and this association was significant at all time intervals (daily, weekly, and monthly) in female adolescents and in the total population. Further, the association was strongest in the daily suicide data. More search term volumes were related to suicide in the daily and weekly data than in the monthly data. There were positive correlations between “suicide,” “self-injury,” and “depression” search volumes.ConclusionFurther studies with larger sample sizes, more search terms, and analysis of time intervals between suicide-related term search and suicide death are required. These studies can contribute to the establishment of an online suicide prevention system to detect suicide risk in adolescents and provide interventions.

4. Association Between Internet Searches Related to Suicide/Self-harm and Adolescent Suicide Death in South Korea in 2016-2020: Secondary Data Analysis

Author: Won-Seok Choi, Junhee Han, and Hyun Ju Hong
Subjects: Computer applications to medicine. Medical informatics, R858-859.7, Public aspects of medicine, RA1-1270
Abstract: BackgroundPrevious studies have investigated the association between suicide and internet search volumes of terms related to suicide or self-harm. However, the results varied by people’s age, period, and country, and no study has exclusively investigated suicide or self-harm rates among adolescents. ObjectiveThis study aims to determine the association between the internet search volumes of terms related to suicide/self-harm and the number of suicides among South Korean adolescents. We investigated gender differences in this association and the time lag between the internet search volumes of the terms and the connected suicide deaths. MethodsWe selected 26 search terms related to suicide and self-harm among South Korean adolescents, and the search volumes of these terms for adolescents aged 13-18 years were obtained from the leading internet search engine in South Korea (Naver Datalab). A data set was constructed by combining data from Naver Datalab and the number of suicide deaths of adolescents on a daily basis from January 1, 2016, to December 31, 2020. Spearman rank correlation and multivariate Poisson regression analyses were performed to identify the association between the search volumes of the terms and the suicide deaths during that period. The time lag between suicide death and the increasing trend in the search volumes of the related terms was estimated from the cross-correlation coefficients. ResultsSignificant correlations were observed within the search volumes of the 26 terms related to suicide/self-harm. The internet search volumes of several terms were associated with the number of suicide deaths among South Korean adolescents, and this association differed by gender. The search volume for “dropout” showed a statistically significant correlation with the number of suicides in all adolescent population groups. The correlation between the internet search volume for “dropout” and the connected suicide deaths was the strongest for a time lag of 0 days. In females, self-harm and academic score showed significant associations with suicide deaths, but academic score showed a negative correlation, and the time lags with the strongest correlations were 0 and –11 days, respectively. In the total population, self-harm and suicide method were associated with the number of suicides, and the time lags with the strongest correlations were +7 and 0 days, respectively. ConclusionsThis study identifies a correlation between suicides and internet search volumes related to suicide/self-harm among South Korean adolescents, but the relatively weak correlation (incidence rate ratio 0.990-1.068) should be interpreted with caution.

5. Characteristics of Korean students advised to seek psychiatric treatment before death by suicide

Author: Hee Jin Kim, Yong-Sil Kweon, and Hyun Ju Hong
Subjects: student, suicide, psychiatric treatment, school, teacher, Psychiatry, RC435-571
Abstract: IntroductionSuicide is the leading cause of death among adolescents in Korea. Psychiatric disorders are well-known risk factors for suicide, but the proportion of children and adolescents who died by suicide and who had received psychiatric treatment is low. This study aims to examine how many school students who died by suicide were advised by their school to seek psychiatric treatment before their death and to characterize their clinical characteristics.MethodsWe analyzed data collected by the Ministry of Education of Korea for all students who died by suicide between 2016 and 2020. Students were grouped according to whether or not they were advised to seek psychiatric treatment by their school-based on mental health screening and teachers’ judgments. Sociodemographic characteristics (sex, educational stage, family structure, and socioeconomic status), suicide-related characteristics (place of suicide, suicide method, suicide note, previous self-harm, and previous suicide attempt), emotional and behavioral status, school life and personal, and family problems were compared between the two groups.ResultsAnalysis was conducted for 544 students, 110 (20.2%) of whom were advised to seek psychiatric treatment by their school before their death. This group had a higher proportion of girls; poorer attendance; higher frequency of depression, anxiety, impulsivity, and social problems; personal problems (appearance, friend-related, and mental and physical health problems); family problems (mental health problems of family, bad relationship with parents, and conflict of parents); and higher incidence of self-harm or suicide attempts (P < 0.001) than the other group.ConclusionTeachers seem to advise psychiatric treatment when mental health problems are revealed at school. It showed distinctive clinical characteristics between the two groups. Preventing suicide among students requires the attention and effort not only of schools, but also of families, communities, and mental health professionals.

Author: Song Jung, Dayoung Lee, Sungjun Park, Kangwoo Lee, Yong-Sil Kweon, Eun-Jin Lee, Kyung Hee Yoon, Hannah Cho, Hyeji Jung, Ah Reum Kim, Bo-Ram Shin, and Hyun Ju Hong
Subjects: Suicide, Adolescent, Gender, Pediatrics, RJ1-570, Psychiatry, RC435-571
Abstract: Abstract Background We investigated the characteristics of adolescents who committed suicide in South Korea, and how these characteristics differed by gender. Method Data from middle and high school students who committed suicide between 2014 and 2016 were analyzed. We evaluated differences in suicide method and place, personal characteristics, and school life characteristics by gender using the Chi square test and t test. Results Jumping from a high place was the most common suicide method for both male and female students. A significantly greater proportion of female adolescents had experienced depressive symptoms, previous self-injury, previous suicide attempts, and had problems with school attendance and peers. Additionally, they were more likely to be classified as high risk according to a school-based mental health screening test and to utilize professional mental health treatment services. Conclusion Our results demonstrate that adolescents who committed suicide exhibited gender differences in personal characteristics and school life. These characteristics might aid in the development of adolescent suicide policies and intervention programs.

Subjects: Childhood, Suicide, Death, Characteristics, Pediatrics, RJ1-570, Psychiatry, RC435-571
Abstract: Abstract Background The purpose of this study was to determine the characteristics of childhood suicidal deaths among elementary school students that occurred from 2011 to 2015 in Korea. Methods The report form of each suicide case by the teacher in charge to the Education Ministry was reviewed retrospectively. Results There were 19 suicidal deaths (12 boys, 7 girls) in elementary school students. The youngest case was a third grader (n = 1). Jumping from heights (n = 12) was the most frequently used method. Most suicides (n = 12) were committed in their homes. Conclusion These results highlight the alarming trend of early suicidal deaths and the importance of early suicide prevention strategies, especially in schools.

Subjects: Medicine, Science
Abstract: OBJECTIVE:This study had two main goals: to examine the structure of co-occurring peer bullying experiences among adolescents in South Korea from the perspective of victims and to determine the effects of bullying on suicidal behavior, including suicidal ideation and suicide attempts, among adolescents. METHOD:This study used data gathered from 4,410 treatment-seeking adolescents at their initial visits to 31 local mental health centers in Gyeonggi Province, South Korea. The structure of peer bullying was examined using latent class analysis (LCA) to classify participants' relevant experiences. Then, a binomial logistic regression adjusted by propensity scores was conducted to identify relationships between experiences of being bullied and suicidal behaviors. RESULTS:The LCA of experiences with bullying revealed two distinct classes of bullying: physical and non-physical. Adolescents who experienced physical bullying were 3.05 times more likely to attempt suicide than those who were not bullied. Victims of (non-physical) cyber bullying were 2.94 times more likely to attempt suicide than were those who were not bullied. CONCLUSIONS:Both physical and non-physical bullying were associated with suicide attempts, with similar effect sizes. Schools and mental health professionals should be more attentive than they currently are to non-physical bullying.

Subjects: RECRUITING & enlistment (Armed Forces), MENTAL health, MILITARY medicine, MINNESOTA Multiphasic Personality Inventory, PEOPLE with mental illness
Abstract: Objective: This study aimed (1) to identify distinct subgroups of psychiatric patients referred for a mental health certificate for military service suitability and (2) to determine whether there is a difference in clinical features such as treatment responsiveness and prognosis among certain subgroups. Methods: We conducted latent profile analysis (LPA) using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical profiles of the participants. Linear mixed model analysis was performed to examine changes in the severity of clinical symptoms and functional level according to the treatment period of the latent classes derived from the LPA. Results: The results indicated that the best-fitting model was a three-class model, comprising Class 1 (mild maladjustment), Class 2 (neurotic depression and anxiety), and Class 3 (highly vulnerable and hypervigilant). We demonstrated that the three subgroups displayed different characteristics in treatment responsiveness and clinical course based on their Clinical Global Impression-Severity and Global Assessment of Functioning scores over a treatment period of 6 months. While subjects in Classes 1 and 2 significantly improved over 6 months, those in Class 3 showed little or no improvement in our clinical parameters. Conclusion: This study has yielded data with clinical implications for treatment planning and interventions for each subgroup classified that were based on MMPI-2 clinical profiles of military recruits who might be maladjusted to serve.

Abstract: Tourette syndrome (TS) is a neuropsychiatric disorder with involvement of genetic and environmental factors. We investigated genetic loci previously implicated in Tourette syndrome and associated disorders in interaction with pre- and perinatal adversity in relation to tic severity using a case-only (N = 518) design. We assessed 98 single-nucleotide polymorphisms (SNPs) selected from (I) top SNPs from genome-wide association studies (GWASs) of TS; (II) top SNPs from GWASs of obsessive–compulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD), and autism spectrum disorder (ASD); (III) SNPs previously implicated in candidate-gene studies of TS; (IV) SNPs previously implicated in OCD or ASD; and (V) tagging SNPs in neurotransmitter-related candidate genes. Linear regression models were used to examine the main effects of the SNPs on tic severity, and the interaction effect of these SNPs with a cumulative pre- and perinatal adversity score. Replication was sought for SNPs that met the threshold of significance (after correcting for multiple testing) in a replication sample (N = 678). One SNP (rs7123010), previously implicated in a TS meta-analysis, was significantly related to higher tic severity. We found a gene–environment interaction for rs6539267, another top TS GWAS SNP. These findings were not independently replicated. Our study highlights the future potential of TS GWAS top hits in gene–environment studies., This research was funded by National Institute of Mental Health (NIMH) grant R01MH092293 (to GAH and JAT) and NJCTS (New Jersey Center for Tourette Syndrome and Associated Disorders; to GAH and JAT).

Abstract: We analyzed the clinical characteristics and suicide-related factors of students who died by suicide in Korea in 2016–2020, based on teachers’ reports. Using data on total suicide deaths (N = 654, mean age = 16.0, 52.6% boys) collected by the Ministry of Education of Korea, we investigated the demographic and clinical characteristics and suicide-related factors of suicide deaths in students aged 9–18 years. Considering gender, more boys (52.6%, N = 344) died by suicide than girls (47.4%, N = 310). About 425 (65.0%) of the suicides were among high school students. The most common suicide method was jumping from a high place (70.6%, N = 454), followed by hanging (25.7%, N = 165). Additionally, 9.4% (N = 48) of the students who died by suicide had a history of attempted suicide, 13.4% (N = 73) had attempted self-harm, and 12.8% (N = 48) were acquainted with someone who had died by suicide. Teachers observed 20.6% (N = 120) of the suicide warning signs at school. Girls tended to have higher rates of attempted suicide, emotional problems, and psychiatric disorders than boys. This study was conducted with the largest sample of Korean suicide students observed at school. Effective suicide-related mental health training for teachers could contribute to suicide prevention in students.

Abstract: Objective Effective suicide prevention for at-risk adolescents requires increased access to medical treatment. Investigating the unique characteristics of suicide in this vulnerable at-risk non-referred sample can contribute to establishing effective suicide prevention policies. This study aimed to (a) examine at-risk non-referred adolescents' suicide attempt rate, (b) investigate influential multilevel factors in predicting these adolescents' suicide attempts, and (c) compare the results of (a) and (b) by gender. Methods A total of 401 samples (216 boys and 185 girls) were recruited through a school-based mental health project for at-risk adolescents. Multivariate hierarchical logistic regression analyses were performed at the individual-, contextual-, and protective levels to evaluate three multilevel models as well as to investigate predictabilities for the overall group and by gender. Results The suicide attempt rate of the overall sample was 29.4% (boys: 18.1%, girls: 42.7%), which was significantly higher than that of community samples. For boys, individual-level predictors (depression and conduct problems) had the most significant contribution in predicting suicide attempts. In contrast, for girls, protective-level predictors (family satisfaction) contributed the most to the prediction of suicide attempts, followed by contextual-level predictors (academic grades). Conclusion This study is an important step in understanding the unique characteristics of at-risk non-referred adolescents who have not yet been considered in mental health policies. Improving medical accessibility will be the first step in establishing effective suicide prevention policies for these vulnerable samples.

Abstract: OBJECTIVE We aimed to investigate the influence of area-level factors on adolescent suicide and to determine which variables differ according to age and sex. METHODS We selected variables that were available for collection through an online database from 2005 to 2015 in the Korean Statistical Information Service and the Korea Labor Institute. We used administrative districts of Korea in 2017 for geographical classification. We examined the relationships between regional suicide rates and area-level variables in male and female subjects aged 10-14 years and 15-19 years. In addition, we analyzed area-level variables in adolescents aged 15-19 years according to sex. RESULTS Our findings indicated that several area-level variables affected adolescent suicide rates, varying according to age and sex. Economic problems were shown to be more associated with suicide in male adolescents than in female adolescents. On the other hand, social fragmentation and health services were shown to be more associated with suicide in females. CONCLUSION Suicide in adolescents was attributable to area-level factors such as economic status, social fragmentation, and community health services. By identifying area-level variables affecting adolescent suicide rates, we will be able to contribute to implement mental health policies related to adolescent suicide.

Abstract: Objective Whether long-acting injectable antipsychotics (LAI) are superior to oral antipsychotics remains a controversial question, and results vary depending on the study design. Our study was performed to compare outcomes of oral anti-psychotics and paliperidone palmitate (PP) in clinical practice by investigating the numbers of admissions and bed days. Methods We performed a retrospective observational mirror-image study at a single medical center, reviewing medical charts to obtain the clinical data. Forty-six patients with a diagnosis of schizophrenia or schizoaffective disorder who had received at least two doses of PP were included in the analysis. The Wilcoxon signed-rank test was used to compare the numbers of bed days and admissions 1 year before starting PP with those numbers at 1 year after. Results The mean number of admissions fell from 0.83 to 0.17 per patient (p < 0.0002), and the median fell from 1 to 0. The mean number of bed days decreased significantly, from 24.85 to 8.74 days (p < 0.006). The outcomes remained similar in sensitivity analyses set up with different mirror points. Conclusion Our results indicate that initiating PP reduced the mean numbers of hospital admissions and bed days compared with prior oral medication. LAIs may thus be cost effective in practice; its use bringing about cost reductions greater than its purchase cost.

Abstract: SUMMARY We previously established the contribution of de novo damaging sequence variants to Tourette disorder (TD) through whole-exome sequencing of 511 trios. Here, we sequence an additional 291 TD trios and analyze the combined set of 802 trios. We observe an overrepresentation of de novo damaging variants in simplex, but not multiplex, families; we identify a high-confidence TD risk gene, CELSR3 (cadherin EGF LAG seven-pass G-type receptor 3); we find that the genes mutated in TD patients are enriched for those related to cell polarity, suggesting a common pathway underlying pathobiology; and we confirm a statistically significant excess of de novo copy number variants in TD. Finally, we identify significant overlap of de novo sequence variants between TD and obsessive-compulsive disorder and de novo copy number variants between TD and autism spectrum disorder, consistent with shared genetic risk., In Brief Wang et al. expand their earlier exome-sequencing work in TD, adding 291 trios and conducting combined analyses suggesting de novo variants carry more risk in individuals with unaffected parents, establishing de novo structural variants as risk factors, identifying CELSR3 as a risk gene, and implicating cell polarity in pathogenesis., Graphical Abstract

Abstract: Genetic studies in Tourette syndrome (TS) are characterized by scattered and poorly replicated findings. We aimed to replicate findings from candidate gene and genome-wide association studies (GWAS). Our cohort included 465 probands with chronic tic disorder (93% TS) and both parents from 412 families (some probands were siblings). We assessed 75 single nucleotide polymorphisms (SNPs) in 465 parent–child trios; 117 additional SNPs in 211 trios; and 4 additional SNPs in 254 trios. We performed SNP and gene-based transmission disequilibrium tests and compared nominally significant SNP results with those from a large independent case–control cohort. After quality control 71 SNPs were available in 371 trios; 112 SNPs in 179 trios; and 3 SNPs in 192 trios. 17 were candidate SNPs implicated in TS and 2 were implicated in obsessive–compulsive disorder (OCD) or autism spectrum disorder (ASD); 142 were tagging SNPs from eight monoamine neurotransmitter-related genes (including dopamine and serotonin); 10 were top SNPs from TS GWAS; and 13 top SNPs from attention-deficit/hyperactivity disorder, OCD, or ASD GWAS. None of the SNPs or genes reached significance after adjustment for multiple testing. We observed nominal significance for the candidate SNPs rs3744161 (TBCD) and rs4565946 (TPH2) and for five tagging SNPs; none of these showed significance in the independent cohort. Also, SLC1A1 in our gene-based analysis and two TS GWAS SNPs showed nominal significance, rs11603305 (intergenic) and rs621942 (PICALM). We found no convincing support for previously implicated genetic polymorphisms. Targeted re-sequencing should fully appreciate the relevance of candidate genes.

Abstract: Background The purpose of this study was to determine the characteristics of childhood suicidal deaths among elementary school students that occurred from 2011 to 2015 in Korea. Methods The report form of each suicide case by the teacher in charge to the Education Ministry was reviewed retrospectively. Results There were 19 suicidal deaths (12 boys, 7 girls) in elementary school students. The youngest case was a third grader (n = 1). Jumping from heights (n = 12) was the most frequently used method. Most suicides (n = 12) were committed in their homes. Conclusion These results highlight the alarming trend of early suicidal deaths and the importance of early suicide prevention strategies, especially in schools.

Abstract: Genetic influences on psychiatric disorders transcend diagnostic boundaries, suggesting substantial pleiotropy of contributing loci. However, the nature and mechanisms of these pleiotropic effects remain unclear. We performed analyses of 232,964 cases and 494,162 controls from genome-wide studies of anorexia nervosa, attention-deficit/hyper-activity disorder, autism spectrum disorder, bipolar disorder, major depression, obsessive-compulsive disorder, schizophrenia, and Tourette syndrome. Genetic correlation analyses revealed a meaningful structure within the eight disorders, identifying three groups of inter-related disorders. Meta-analysis across these eight disorders detected 109 loci associated with at least two psychiatric disorders, including 23 loci with pleiotropic effects on four or more disorders and 11 loci with antagonistic effects on multiple disorders. The pleiotropic loci are located within genes that show heightened expression in the brain throughout the lifespan, beginning prenatally in the second trimester, and play prominent roles in neurodevelopmental processes. These findings have important implications for psychiatric nosology, drug development, and risk prediction.

Abstract: Whole-exome sequencing (WES) and de novo variant detection have proven a powerful approach to gene discovery in complex neurodevelopmental disorders. We have completed WES of 325 Tourette disorder trios from the Tourette International Collaborative Genetics cohort and a replication sample of 186 trios from the Tourette Syndrome Association International Consortium on Genetics (511 total). We observe strong and consistent evidence for the contribution of de novo likely gene-disrupting (LGD) variants (rate ratio [RR] 2.32, p = 0.002). Additionally, de novo damaging variants (LGD and probably damaging missense) are overrepresented in probands (RR 1.37, p = 0.003). We identify four likely risk genes with multiple de novo damaging variants in unrelated probands: WWC1 (WW and C2 domain containing 1), CELSR3 (Cadherin EGF LAG seven-pass G-type receptor 3), NIPBL (Nipped-B-like), and FN1 (fibronectin 1). Overall, we estimate that de novo damaging variants in approximately 400 genes contribute risk in 12% of clinical cases. Video Abstract [Figure presented]

20. Gender-based Multilevel Analysis of Influential Factors for Suicide Attempts among At-risk Non-referred Adolescents in Korea.

Author: Yumi Lee, Dayoung Lee, and Hyun Ju Hong
Subjects: SUICIDAL behavior, MULTILEVEL models, FACTOR analysis, TEENAGERS, GENDER mainstreaming, SUICIDE prevention
Abstract: Objective: Effective suicide prevention for at-risk adolescents requires increased access to medical treatment. Investigating the unique characteristics of suicide in this vulnerable at-risk non-referred sample can contribute to establishing effective suicide prevention policies. This study aimed to (a) examine at-risk non-referred adolescents' suicide attempt rate, (b) investigate influential multilevel factors in predicting these adolescents' suicide attempts, and (c) compare the results of (a) and (b) by gender. Methods: A total of 401 samples (216 boys and 185 girls) were recruited through a school-based mental health project for at-risk adolescents. Multivariate hierarchical logistic regression analyses were performed at the individual-, contextual-, and protective levels to evaluate three multilevel models as well as to investigate predictabilities for the overall group and by gender. Results: The suicide attempt rate of the overall sample was 29.4% (boys: 18.1%, girls: 42.7%), which was significantly higher than that of community samples. For boys, individual-level predictors (depression and conduct problems) had the most significant contribution in predicting suicide attempts. In contrast, for girls, protective-level predictors (family satisfaction) contributed the most to the prediction of suicide attempts, followed by contextual-level predictors (academic grades). Conclusion: This study is an important step in understanding the unique characteristics of at-risk non-referred adolescents who have not yet been considered in mental health policies. Improving medical accessibility will be the first step in establishing effective suicide prevention policies for these vulnerable samples. [ABSTRACT FROM AUTHOR]

21. Four-year trajectory of Korean youth mental health and impacts of school environment and school counselling: a observational study using national schools database.

Author: Seongjun Park, Dayoung Lee, Song Jung, and Hyun Ju Hong
Abstract: Objectives This study aimed to investigate changes in the mental health status of South Korean adolescents at a school level and identify school-related factors affecting these changes. Design A retrospective data analysis, population study. Setting South Korean high schools from 2013 to 2016. Participants Randomly sampled 827 schools (316 834 boys and 299 304 girls) Primary outcome measures Mean scores of the Adolescent Mental Health and Problem Behavior Questionnaire-II (AMPQ-II), a school-based mental health screening test, were used to explore changes in youth mental health. Data regarding the school environment and school counselling were gathered from the ‘School info’ website. A multilevel growth model was used to determine relationships between students’ mental health and school-related factors. Results Students’ mental health statuses in South Korea gradually improved over time (coefficient=−1.46 to −1.70, p<0.001). School mobility rates (coefficient=0.93 to 1.00, p<0.05), school dropout rates (coefficient=0.38 to 0.40, p<0.001), school budgets per student (coefficient=−0.05 to −0.06, p<0.01) and number of school counselling sessions (coefficient=0.14, p<0.01) were significantly associated with baseline AMPQ-II scores. The rate of change in AMPQ-II score increased when the number of school counselling sessions was higher (coefficient=−0.03, p<0.05) or the school budget was lower (coefficient=0.02, p<0.001). School environment explained 21.6% of the AMPQ-II baseline score variance and 9.3% of the rate of change variance. School counselling further explained 2.0% of the variance in baseline AMPQ-II scores and 2.3% of the rate of change variance. Conclusions This study suggests that school environment stability and active provision of school-based mental health services have a positive impact on youth mental health. [ABSTRACT FROM AUTHOR]

Subjects: PEOPLE with schizophrenia, WILCOXON signed-rank test, AMISULPRIDE, HOSPITAL beds, MEDICAL centers, SCHIZOAFFECTIVE disorders, COST control, PEBBLE bed reactors
Abstract: Objective: Whether long-acting injectable antipsychotics (LAI) are superior to oral antipsychotics remains a controversial question, and results vary depending on the study design. Our study was performed to compare outcomes of oral antipsychotics and paliperidone palmitate (PP) in clinical practice by investigating the numbers of admissions and bed days. Methods: We performed a retrospective observational mirror-image study at a single medical center, reviewing medical charts to obtain the clinical data. Forty-six patients with a diagnosis of schizophrenia or schizoaffective disorder who had received at least two doses of PP were included in the analysis. The Wilcoxon signed-rank test was used to compare the numbers of bed days and admissions 1 year before starting PP with those numbers at 1 year after. Results: The mean number of admissions fell from 0.83 to 0.17 per patient ( p < 0.0002), and the median fell from 1 to 0. The mean number of bed days decreased significantly, from 24.85 to 8.74 days ( p < 0.006). The outcomes remained similar in sensitivity analyses set up with different mirror points. Conclusion: Our results indicate that initiating PP reduced the mean numbers of hospital admissions and bed days compared with prior oral medication. LAIs may thus be cost effective in practice; its use bringing about cost reductions greater than its purchase cost. [ABSTRACT FROM AUTHOR]

Abstract: Objective: This study explored the clinical characteristics and risk factors of suicidal ideation in a sample of first graders from South Korea. Children's depression and aggression and maternal depression were examined as possible risk factors. Methods: This study is a school-based, cross-sectional study of 5 elementary schools in Gunpo City, South Korea. Participants were 707 first graders (mean age, 6.54 years) and their mothers. We assessed children's depressive and aggressive symptoms using the Behavior Assessment System for Children-2 (BASC-2) and maternal depression using the Beck Depression Inventory (BDI). Two items from BASC-2 and 1 item from BDI identified children's and maternal suicidal ideation. Results: Twenty-seven (3.8%) children evidenced suicidal ideation. Children with suicidal ideation had higher mean scores of depression domain (10.11 ± 5.34 vs 4.57 ± 3.44, P < .0001) and aggression domain (7.78 ± 3.84 vs 3.80 ± 2.85, P < .0001) on BASC-2 and maternal depression (9.78 ± 6.45 vs 7.28 ± 5.38, P = .02) on BDI. In regression analysis, children's depression (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.07-1.32; P = .001) and aggression (OR, 1.24; 95% CI, 1.08-1.41; P = .002) contributed significantly to children's suicidal ideation, whereas maternal depression was not significantly related to children's suicidal ideation (OR, 0.99; 95% CI, 0.92-1.06; P = .75). Conclusions: This study demonstrated that even first graders had a considerable prevalence of suicidal ideation and that depression and aggression were associated with suicidal ideation in young children.

24. Cross-Cultural Aspect of Behavior Assessment System for Children-2, Parent Rating Scale-Child: Standardization in Korean Children.

Author: Jungeun Song, Leventhal, Bennett L., Yun-Joo Koh, Keun-Ah Cheon, Hyun Ju Hong, Young-Key Kim, Kyungjin Cho, Eun-Chung Lim, Jee In Park, and Young-Shin Kim
Abstract: Purpose: Our study aimed to examine psychometric properties and cross-cultural utility of the Behavior Assessment System for Children-2, Parent Rating Scale-Child (BASC-2 PRS-C) in Korean children. Materials and Methods: Two study populations were recruited: a general population sample (n=2115) of 1st to 6th graders from 16 elementary schools and a clinical population (n=219) of 6-12 years old from 5 child psychiatric clinics and an epidemiological sample of autism spectrum disorder. We assessed the validity and reliability of the Korean version of BASC-2 PRS-C (K-BASC-2 PRS-C) and compared subscales with those used for US populations. Results: Our results indicate that the K-BASC-2 PRS-C is a valuable instrument with reliability and validity for measuring developmental psychopathology that is comparable to those in Western population. However, there were some differences noted in the mean scores of BASC-2 PRS-C between Korean and US populations. Conclusion: K-BASC-2 PRS-C is an effective and useful instrument with psychometric properties that permits measurement of general developmental psychopathology. Observed Korean-US differences in patterns of parental reports of children's behaviors indicate the importance of the validation, standardization and cultural adaptation for tools assessing psychopathology especially when used in populations different from those for which the instrument was originally created.

25. Predictors of Suicide Attempts in Clinically Depressed Korean Adolescents.

Author: Ahye Kwon, Jungeun Song, Ki-Hwan Yook, Duk-ln Jon, Myung Hun Jung, Narei Hong, and Hyun Ju Hong
Subjects: SUICIDAL behavior, TEENAGERS
Abstract: We examined predictors of suicide attempts in clinically depressed adolescents in Korea and gender differences in suicidal behavior. In total, 106 adolescents diagnosed with depressive disorder were recruited in South Korea. We assessed various variables that might affect suicide attempts, and used a structured interview for the diagnosis of depression and comorbidities and to evaluate suicidality. Demographic and clinical characteristics of the subjects were compared between suicide attempt and non-suicide attempt groups and we examined significant predictors of suicide attempts. Gender differences in suicidal ideation and suicidal behavior were also analyzed. Among 106 depressed participants, 50 (47.2%) adolescents were classified in the suicide attempt group. Generally, the suicide attempt and non-suicide attempt group shared similar clinical characteristics. The suicide attempt group had more females, more major depressive disorder diagnoses, more depressive episodes, and higher suicidal ideation than the non-suicide attempt group. Suicidal ideation was the only significant predictor of suicidal attempt, regardless of gender. Higher suicidal ideation frequency scores and more non-suicidal self-injurious behaviors were shown in the female suicide attempt group than the male suicide attempt group. It is recommended that suicidal ideation be assessed regularly and managed rigorously to decrease suicide risks in depressive adolescents. [ABSTRACT FROM AUTHOR]

26. Effects of resveratrol on the insulin signaling pathway of obese mice.

Author: Hyun Ju Hong, Wonyoung Kang, Dong Geon Kim, Dae Ho Lee, Youngjae Lee, and Chang-Hoon Han
Abstract: The present study was conducted to investigate the effects of resveratrol on the insulin signaling pathway in the liver of obese mice. To accomplish this, we administered resveratrol to high fat diet-induced obese mice and examined the levels of protein phosphorylation in the liver using an antibody array. The phosphorylation levels of 10 proteins were decreased in the high fat diet and resveratrol (HFR) fed group relative to the levels in the high fat diet (HF) fed group. In contrast, the phosphorylation levels of more than 20 proteins were increased in the HFR group when compared with the levels of proteins in the HF group. Specifically, the phosphorylation levels of Akt (The308, Tyr326, Ser473) were restored to normal by resveratrol when compared with the levels in the HF group. In addition, the phosphorylation levels of IRS-1 (Ser636/Ser639), PI-3K p85-subunit α /γ (Tyr467/Tyr199), PDK1 (Ser241), GSK-3α (S21) and GSK-3 (Ser9), which are involved in the insulin signaling pathway, were decreased in the HF group, whereas the levels were restored to normal in the HFR group. Overall, the results show that resveratrol restores the phosphorylation levels of proteins involved in the insulin signaling pathway, which were decreased by a high fat diet. [ABSTRACT FROM AUTHOR]

Subjects: *MENTAL depression, *MENTAL health services, *PERCEIVED Stress Scale, *MENTAL health, *PSYCHOLOGICAL stress
Abstract: Depressive symptoms of employees reduce their quality of life and cause loss of work competence. The importance of mental health is not only applied to private workers but also to municipal personnel. However, there was not enough study on the mental health characteristics of municipal personnel in Korea. Therefore, this study aims to investigate depressive symptoms and attitudes toward suicide among municipal personnel of one metropolitan city near Seoul, and to identify the characteristics of those with depressive symptoms. We send SMS to all 1,012 municipal personnel in this city for this survey. The survey consisted of sociodemographic characteristics, CES-D (The Centre for epidemiologic studies depression scale), PSS (Perceived Stress Scale), GAD-7 (The 7-item Generalized Anxiety Disorder Scale), and perceptions and attitudes toward suicide. : The survey was conducted on 367 municipal personnel in one city who voluntarily agreed to the survey. Forty percent of subjects suffered from depressive symptoms. Although the prevalence of depressive symptoms was not different by sex, there were more younger age subjects in the depressive symptom group (p=0.004) than control. Also, in the depressive symptom group, there were more subjects with psychological stress (p<0.001) and anxiety symptoms (p<0.001) than without depressive symptoms. Many of the study subjects showed a permissive attitude toward suicide. The ratio of agreeing to the rationality of suicide (p<0.001) and accepting attitude toward suicide (p<0.001) was higher in the depressive group than control. Many municipal personnel had depressive symptoms and a permissive attitude toward suicide. The results of this study can be used to develop more appropriate mental health services targeting people with depressive symptoms among municipal personnel in Korea. [ABSTRACT FROM AUTHOR]
