RESUMEN
Urinary angiotensinogen (AGT) is potentially a specific biomarker for the status of the intrarenal renin-angiotensin system (RAS) in patients with diabetes mellitus. We explored whether changes in urinary AGT excretion levels were associated with the deterioration of kidney function in type 2 diabetes patients with preserved kidney function. Urinary baseline AGT levels were measured in 118 type 2 diabetic patients who were not taking RAS blockers and who had estimated glomerular filtration rates (eGFRs) ≥ 60 mL/min/1.73 m². A total of 91 patients were followed-up for 52 months. Changes in urinary levels of AGT (ΔAGT) were calculated by subtracting urinary AGT/creatinine (Cr) at baseline from urinary AGT/Cr after 1 year. ΔAGT was significantly inversely correlated with annual eGFR change (ß = -0.29, P = 0.006; ß = -0.37, P = 0.001 after adjusting for clinical factors). RAS blockers were prescribed in 36.3% of patients (n = 33) during follow-up. The ΔAGT values were lower in the RAS blockers users than in the non-RAS blockers users, but the differences were not statistically significant (7.37 ± 75.88 vs. 22.55 ± 57.45 µg/g Cr, P = 0.081). The ΔAGT values remained significantly correlated with the annual rate of eGFR change (ß = -0.41, P = 0.001) in the patients who did not use RAS blockers, but no such correlation was evident in the patients who did. ΔAGT is inversely correlated with annual changes in eGFR in type 2 diabetes patients with preserved kidney function, particularly in RAS blocker-naïve patients.

OBJECTIVE: The aim of this study is to evaluate the relation between suicidal ideation, allergic diseases, and excessive Internet use in Korean youth using a national representative dataset. METHODS: Data from the Korean Youth Risk Behavior Web-Based Survey (KYRBWS), conducted by the Korean Centers for Disease Control and Prevention, were used in this study. Complex sample logistic regression and structural equation modeling were performed to define the relation between suicidal ideation, allergic disease and excessive Internet use. RESULTS: A total of 73,238 students participated in this survey. In Korea, 19.3% of adolescents had suicidal ideation in the previous year. Asthma (OR=1.23, 95% CI=1.15-1.32, p<0.01) and allergic rhinitis (OR=1.17, 95% CI=1.11-1.22, p<0.01) were identified as risk factors for suicidal ideation after adjusting for school and family factors. Structural equation modeling showed that excessive Internet use interacted with the association between allergic diseases and suicidal ideation. CONCLUSION: Allergy problems could positively affect suicidal ideation in Korean adolescents. Excessive Internet use could be a mediating factor between allergic disease and suicidal ideation.

OBJECTIVE: The suicide rate in Korea was the highest among countries in the Organisation for Economic Co-operation and Development in 2019. In a previous study, higher intake of vegetables and fruits was associated with a lower risk of suicidal ideation, and carotene-rich fruits and vegetables lowered the risk of depression. This study aimed to examine the direct relationship between carotene intake and suicidal ideation, adjusting for the effect on depression. METHODS: This study used data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2012, 2013, and 2015. Carotene intake was assessed through a food intake frequency survey with a 24-hour recall. Suicidal ideation and depression were assessed using the mental health section of the KNHANES. We applied logistic regression to assess the relationship between carotene intake and suicidal ideation, adjusting for potential confounders. RESULTS: A total of 5,480 females aged 19-64 years were included in this study. Carotene intake was significantly lower in the suicidal ideation group (3,034.5±1,756.4 µg/day) than in the nonsuicidal ideation group (3,225.4±1,795.1 µg/day) (p=0.015). We found a significant inverse association between carotene intake and the risk of suicidal ideation after adjusting for potential confounders (odds ratio=0.934, 95% confidence interval=0.873-0.999). CONCLUSION: These results suggest that carotene intake may be inversely associated with the risk of suicidal ideation. Our findings may inform the development of new nutritional interventions to prevent increases in the risk of suicide worldwide.
RESUMEN
Objective: When analyzing factors related to suicide, it is necessary to consider the regional characteristics of the areas where individuals live in addition to individual factors. This study aimed to investigate the spatiotemporal association between suicide rates and geographic features and the patterns of this association for all administrative areas in South Korea from 2009 to 2019. Methods: The data used in this study were obtained from the National Statistical Office of the Korean Statistical Information Service. For suicide rates, age-standardized mortality index data per 100 000 people were used. All administrative districts from 2009 to 2019 were divided into 229 regions. Emerging hotspot analysis was used for a 3-dimensional analysis to simultaneously evaluate temporal and spatial clusters. Results: In the 229 regions, there were 27 (11.8%) hotspots and 60 (26.2%) cold spots. Hotspot pattern analysis found 2 (0.9%) new spots, 1 (0.4%) persistent spot, 23 (10.0%) sporadic spots, and 1 (0.4%) oscillating spot. Conclusion: This study found geographic differences in the spatiotemporal patterns of suicide rates in South Korea. The utilization of national resources for suicide prevention should be selectively and intensively prioritized in 3 areas that exhibit unique spatiotemporal patterns.
RESUMEN
Puberty, at which point girls experience menarche, is a biologically and psychologically unstable period. This study investigated the association between early menarche and suicidal ideation in girls. This study analyzed data from approximately 35,000 girls from the Korea Youth Risk Behavior Web-Based Survey every year from 2011 to 2015. The odds ratios of suicidal ideation were compared between the early and average menarche groups. Generally, the odds ratios of suicidal ideation in girls with early menarche were significantly higher than those with average menarche.

This study investigated the effect of emotional stability (ES) on insomnia through anxiety in preoperative patients with cataracts. Fifty-four subjects completed a self-questionnaire that included the Insomnia Severity Index (ISI), the International Personality Item Pool (IPIP) for ES, and the Hospital Anxiety and Depression scale (HADS). Pathway analysis was performed to analyze the mediating effects of ES, the anxiety subscale scores of the HADS, and the ISI scores. The low-ES group exhibited an insomnia severity that was significantly higher than that of the high-ES group (p=0.048). According to the pathway analysis, the significant indirect effect of ES on the ISI scores was mediated by the scores on the anxiety subscale of the HADS. Cataract patients with low ES waiting to undergo surgery have a high risk of experiencing insomnia due to anxiety. Before surgery, it is essential to identify patients' personality characteristics and provide appropriate intervention.
RESUMEN
OBJECTIVE: Resilience and impulsivity have opposite effects on depression in stressful situations. This study aimed to investigate the association among resilience, impulsivity, and depression in young males. METHODS: The participants consisted of 429 conscripts who underwent military training over 5 weeks. The surveys included the Connors- Davidson Resilience Scale-Korean version, the Barratt Impulsiveness Scale-11-Revised, and the Center for Epidemiological Studies- Depression Scale. The surveys were administered both before and after training. RESULTS: When simultaneously considering impulsivity and resilience, resilience was not associated with depression. Impulsivity had a complete negative mediating effect on resilience and depressive symptoms. Impulsivity is a significant negative mediating factor for the protective effect of resilience on depression. CONCLUSION: This study recommends considering impulsivity when evaluating the protective role of resilience against depression.
RESUMEN
BACKGROUND: Few studies have examined the effects of resilience on quality of life (QOL) in patients with bipolar disorder (BD). Therefore, this study investigated the association between resilience and QOL in patients with BD and compared it to the relationship between resilience and QOL in healthy individuals. METHODS: Participants were 68 euthymic patients with BD and 68 age-, sex-, and length of education-matched controls. Sociodemographic characteristics and clinical variables of the two groups were obtained using face-to-face interviews, and all participants completed the Connor-Davidson Resilience Scale, the World Health Organization QOL-Brief Form. RESULTS: The QOL of the BD group was significantly impaired compared with that of the controls. Degree of resilience, number of depressive episodes, Clinical Global Impression scores, degree of impulsivity, and length of education were significantly correlated with QOL in the BD group. Resilience was significantly associated with overall QOL, physical subdomains of QOL, psychological subdomains of QOL, social subdomains of QOL, and environmental subdomains of QOL in the BD group, even after controlling for confounders. In the control group, resilience was significantly associated with overall QOL, the physical subdomains of QOL, psychological subdomains of QOL, and social subdomains of QOL. LIMITATIONS: The number of participants in each group was 68, which is a relatively small sample size. CONCLUSIONS: Resilience in patients with BD was independently and positively correlated with various areas of QOL. Various strategies to reinforce resilience in patients with BD are needed to improve the low QOL in this population.

OBJECTIVE: This study investigated whether the resilience of males with probable bipolar depression (PBD) can be strengthened and compared it to that of males with probable unipolar depression (PUD). METHODS: Prospective data for 198 participants (PBD: 66, PUD: 66, normal control: 66) were analyzed. The participants' resilience, bipolarity and severity of depressive symptoms were evaluated at baseline and after 5 weeks. Analysis of variance (ANOVA) and repeated measure ANOVA was performed for comparing resilience between three groups through a basic military training. RESULTS: The PBD group demonstrated more resilience than the PUD group at baseline. Participants with PBD became significantly more resilient than participants with PUD after 5 weeks (p<0.01, F=6.967, η2p=0.052). CONCLUSION: The study indicates that interventions that strengthen resilience need to be developed for males with PBD and that such interventions are more effective for males with PBD than PUD.
RESUMEN
OBJECTIVE: The aim of this study was to investigate whether depressive symptoms affect the relationship between adult attention deficit hyperactivity disorder (ADHD) and the quality of life (QOL) in Korean soldiers. METHODS: We evaluated past and present symptoms of adult ADHD (the Korean Adult Attention-Deficit/Hyperactivity Disorder Scale and the Wender Utah Rating Scale), depression (the Center for Epidemiological Studies Depression Scale) and QOL (the Korean version of the SmithKline Beecham 'Quality of Life' scale) in 131 soldiers during mental health screenings performed by a local mental health center. A structured equation model using AMOS 19.0 was used to evaluate the mediating effect of depression. RESULTS: In our first model (without depressive symptoms), adult ADHD significantly affected QOL (standardized regression weight=-0.51, p<0.01). After depressive symptoms were added to this model, the direct effect of adult ADHD on QOL was not significant (standardized regression weight=0.10, p=0.43). Regarding the indirect effect, adult ADHD significantly affected depression (standardized regression weight=0.78, p<0.01), and depression also affected QOL (standardized regression weight=-0.79, p<0.01). CONCLUSION: Through structural equation modeling, the complete mediation model for the influence of depressive symptoms on ADHD and QOL was confirmed. These findings indicated that it might be important to consider comorbidities, such as depression, when adult ADHD is being evaluated.
RESUMEN
The aim of this study was to investigate the relationship between metabolic syndrome and suicidal ideation in Korean. This study was based on the 2010 Korean National Health and Nutrition Examination Survey. A questionnaire was used to measure suicidal ideation and physical examination was performed to measure waist circumference, blood pressure, fasting glucose, cholesterol and triglyceride levels. Complex samples logistic regression was performed to estimate the relationship between metabolic syndrome and suicidal ideation among adults and adolescents. Subjects with metabolic syndrome were more likely to have suicidal ideation in adult. There would be essential needs to evaluate suicidal ideation in adult with metabolic syndrome and to follow up suicidal ideation in adolescents with metabolic syndrome.
RESUMEN
PURPOSE: The purpose of this study was to use meta-analysis to examine recent domestic articles related to attention deficit hyperactivity disorder (ADHD) in school-age children. METHODS: After reviewing 213 articles published between 1990 and 2009 from and cited in RISS, KISS, and DBpia, the researchers identified 24 studies with 440 research variables that had appropriate data for methodological study. SPSS 17.0 program was used. The outcome variables were divided into five types: Inattention, hyperactive impulsive, intrinsic, extrinsic, and academic ability variables. RESULTS: Effects size of overall core symptoms was 0.47 which is moderate level in terms of Cohen criteria and effects size of overall negative variables related ADHD was 0.27 which is small level. The most dominant variable related to ADHD was obtained from hyperactive-impulsive (0.70). Also academic ability (0.45), inattention (0.37), and intrinsic variables (0.29) had a small effect whereas extrinsic variables (0.13) had little effect on descriptive ADHD study. CONCLUSION: The results reveal that ADHD core symptoms have moderate effect size and peripheral negative variables related ADHD have small effect size. To improve the reliability of the meta-analysis results by minimizing publication bias, more intervention studies using appropriate study designs should be done.
