OBJECTIVE: A considerable proportion of suicide attempts are the result of sudden desires. Understanding such impulsive suicide attempts is necessary for effective interventions. We evaluated the impulsivity of suicide attempters treated in emergency rooms. The aim of the study was to identify the characteristics of impulsive suicide attempts by comparing these individuals to those who attempted to commit suicide in a non-impulsive manner. METHODS: This study analyzed suicide attempters who visited the emergency departments of seven selected university hospitals. A total of 269 medical records in which impulsivity of suicide attempt were confirmed were subject to be analyzed. The impulsivity of the suicide attempt was examined using a summative score of items 6 and 15 on the Suicide Intent Scale. RESULTS: A total of 48.0% of the participants were impelled by sudden inclinations to attempt suicide. Impulsive attempters were younger, unmarried and less physical illness than non-impulsive attempters, whereas no significant differences were found on psychiatric history and previous suicide history. Impulsive suicide attempters had suicide ideations that were not as severe (χ2=55.33, p<0.001) or intense (t=-8.38, p<0.001) as their counterparts'. Furthermore, medical results of impulsive suicide attempts were better than non-impulsive suicide attempts (t=-3.77, p<0.001). CONCLUSION: The results suggested that a considerable proportion of suicide attempts were the result of sudden inclinations. Impulsive attempts were made in relatively earlier stages of suicide ideation; consequently, they have less intent than non-impulsive attempts.

OBJECTIVES: The purpose of this study was to develop and evaluate an application (app) that provides tailored recommendations based on lifestyle and clinical data entered by the user. METHODS: Knowledge and functions required for the gestational diabetes mellitus (GDM) management app were extracted from clinical practice guidelines and evaluated through an online survey. Common and tailored recommendations were developed and evaluated with a content validity index. Algorithms to link tailored recommendations with a patient's data were developed and evaluated by experts. An Android-based app was developed and evaluated by comparing the process of data entry and recommendation retrieval and the usability of the app. After the app was revised, the user acceptance of the app was evaluated. RESULTS: Six domains of knowledge and 14 functions were extracted. Seven common and 49 tailored recommendations were developed. Nine lifestyle and clinical data elements were modeled. Eight algorithms with 18 decision nodes presenting tailored recommendations based on patient's data and 12 user interface screens were developed. All recommendations obtained from the use of app concurred with recommendations derived by algorithms. The average usability score was 69.5 out of 100. The user acceptance score with behavioral intention to use was 5.5, intrinsic motivation 4.3, the perceived ease of use score was 4.6, and the perceived usefulness score was 5.0 out of 7, respectively. CONCLUSIONS: The GDM management knowledge and tailored recommendations obtained in this study could be of help in managing GDM.

PURPOSE: To report two cases of spontaneous suprachoroidal hemorrhage associated with wet type of age-related macular degeneration (ARMD) and systemic hypertension. CASE SUMMARY: Two women, aged 76 and 73 years, with a history of systemic hypertension for more than ten years had been treated in an eye clinic for wet type of ARMD. The 76-year-old woman was scheduled to receive an injection of intravitreal Lucentis(R) but experienced sudden onset loss of vision and ocular pain in her left eye. The 73-year-old woman had received no specific treatment for wet type of ARMD. She also complained of visual disturbance and ocular pain. In these two cases, slit lamp or B-scan examination disclosed suprachoroidal hemorrhage. Surgical intervention relieved the ocular pain and symptoms in both cases. CONCLUSIONS: Even if a patient has not received systemic anticoagulation/thrombolytic therapy, if wet-type ARMD patients are elderly and have systemic hypertension, they should receive regular follow-ups because old age and systemic hypertension are risk factors of spontaneous suprachoroidal hemorrhage.

OBJECTIVES: In the current study, we investigated the general characteristics of suicide attempters and attempted to determine factors contributing to suicide attempt by analyzing severe suicide ideation and intent. METHODS: This study analyzed medical records of suicide attempters who visited the emergency departments. Data were collected from 7 university hospitals nationwide. As an evaluation measure of suicide intent, we used Suicide Intent Scale (SIS). Colombia Suicide Severity Rating Scale (C-SSRS) was applied for assessment of severity and intensity of suicide idea and lethality of suicide behavior. RESULTS: Male gender, old age and living alone group showed higher SIS score. Male gender, low income, and having psychiatric diagnosis or suicide history group showed a high score on the severity subscale of suicide ideation of C-SSRS. Old age, low income, and having psychiatric diagnosis showed a high score on the intensity subscale of suicide ideation of C-SSRS. Actual lethality scale of C-SSRS was high in male gender and old age group. Severity and intensity of suicide ideation and suicide intent showed positive correlation with actual lethality of suicide behavior. CONCLUSION: Male gender, old age, living alone, psychiatric diagnosis, and suicide history were risk factors affecting severity and intensity of suicide ideation and intent of suicide. Severity and intensity of suicide ideation and intent are positively related to lethality of suicide behavior.

Purpose: This study investigated knowledge, attitudes, and nursing stress related to lifesustaining treatment among oncology nurses. Methods: A descriptive study design was used. Data were collected through a survey from April 1 to May 31, 2022. The participants were 132 nurses working in the oncology ward of a tertiary hospital in Seoul. Data were analyzed using the SPSS 25.0 program with descriptive statics, the independent t-test, analysis of variance, and Pearson correlation coefficients. Results: The average scores for knowledge, attitudes, and nursing stress related to life-sustaining treatment were 14.42, 3.29, and 3.96, respectively. Significant differences in knowledge about life-sustaining treatment were observed based on clinical experience (P=0.029) and education about life-sustaining treatment (P=0.044). Attitudes toward life-sustaining treatment varied significantly with education about life-sustaining treatment (P=0.014), while stress levels differed significantly across working units (P=0.004). A positive correlation was found between the dilemma of extending or stopping life-sustaining treatment (a subdomain of nursing stress) and attitudes toward life-sustaining treatment (r=0.260, P=0.003). Conclusion There was no significant correlation between the nursing stress experienced by oncology nurses and their knowledge and attitudes toward life-sustaining treatment. However, a more positive experience with life-sustaining treatment education was associated with higher stress levels related to the dilemma of extending or stopping life-sustaining treatment. Therefore, it is crucial to develop strategies to manage this dilemma and reduce stress in the field.

A colo-uterine fistula is a rare complication of diverticular disease, due to the resistance of the uterine tissue. Only 18 cases have been reported in the world literature. Here, a case of an 82-year-old woman, with a colo-uterine fistula secondary to diverticulitis, is described. She presented with a malodorous vaginal discharge. A barium enema revealed colonic diverticulosis with a fistula tract to the body of uterus. The clinical symptoms were not specific, with the exception of the purulent material and stools from the vagina. A Sigmoidectomy, with fistula tract removal, and simple closure of the uterus was performed curatively.

Maturity-onset diabetes of the young (MODY) is a rare, autosomal dominant disease characterized by non-ketogenic diabetes mellitus (DM). MODY type 4, caused by PDX1 mutation, is a very rare subtype of MODY, especially in Korea. We report a case of a 10-year-old, nonobese girl with a family history of type 2 DM. After diagnosis, the patient’s serum glucose level was well controlled using metformin monotherapy; however, the glycated hemoglobin level increased to 9.0% approximately 2 years after treatment. No obesity or lifestyle problems were observed, and serum fasting C-peptide level was within the normal range. Furthermore, no islet-related autoantibodies were detected. A genetic screening for MODY using a next-generation sequencing panel was performed, and a likely heterozygous pathogenic PDX1 mutation (p.Gly246ArgfsTer21) was identified. The PDX1 variant was not detected in her mother, implying that the mutation had arisen de novo in the proband. She was prescribed insulin degludec in addition to metformin therapy, which improved her hyperglycemia. This report presents a novel MODY type 4 phenotype and highlights the importance of genetic screening in patients with MODY characteristics.

OBJECTIVES: Since 2003 South Korea's suicide rate has remained the highest among Organization for Economic Cooperation and Development countries. Gatekeeper training is a major strategy in the national suicide prevention plan in Korea. In this study, we evaluated the effect of the Korean standardized suicide prevention program on the gatekeeper's intervention, developed by the Korea Association for Suicide Prevention and implemented by the Korea Suicide Prevention Center. METHODS: A telephone survey was conducted in order to assess awareness and intervention for the high risk group. Out of the 35825 people who completed the educational course in 2013, 800 gatekeepers were selected by proportional quota sampling. RESULTS: Of the 800 subjects, 93% answered that people in the high risk group of suicide sent diverse signals implying suicide ; 19.9% of the gatekeepers found actual high risk suicidal people, 95% of whom listened to why they came to think about suicide and 71.5% of listeners gave information about suicide prevention and referred them to mental health professionals. CONCLUSION: The Korean standardized suicide prevention program may be helpful to the gatekeepers in playing an adequate role in intervention, but further study is needed in order to evaluate long-term educational effects.

BACKGROUND: Sorbus rufopilosa, a tsema rowan, is a species of the small ornamental trees in the genus Sorbus and the family Rosaceae found in East Asia. The bioactivities of S. rufopilosa have not yet been fully determined. The objective of this study is to evaluate the antioxidant and anticancer effects of ethanol extract of S. rufopilosa (EESR) and to determine the molecular mechanism of its anticancer activity in human colon carcinoma HT29 cells. METHODS: To examine the antioxidant activity of EESR, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity assay was performed. Inhibitory effect of EESR on cancer cell growth and proliferation was determined by water-soluble tetrazolium salt assay. To investigate the mechanism of EESR-mediated cytotoxicity, HT29 cells were treated with various concentrations of EESR and the induction of cell cycle arrest and apoptosis was analyzed by flow cytometry, 4,6-diamidino-2-phenylindole staining, and Western blot analysis. RESULTS: EESR showed significant antioxidant activity and inhibitory effect on HT29 cell growth in a dose-dependent manner. EESR induced cell cycle arrest at G2/M phase in a dose-dependent manner by modulating cyclin B, cyclin-dependent kinase 1 (CDK1), and CDK inhibitor p21 expression. EESR-induced apoptosis was associated with the upregulation of p53, a death receptor Fas, and a pro-apoptotic protein Bax and the activation of caspase 3, 8, and 9, resulting in the degradation of PARP. CONCLUSIONS: EESR possessing antioxidant activity efficiently inhibits proliferation of HT29 cells by inducing both cell cycle arrest and apoptosis. EESR may be a possible candidate for the anticancer drug development.

Background: To propose a deep learning architecture for automatically detecting the complex structure of the aortic annulus plane using cardiac computed tomography (CT) for transcatheter aortic valve replacement (TAVR). Methods: This study retrospectively reviewed consecutive patients who underwent TAVR between January 2017 and July 2020 at a tertiary medical center. Annulus Detection Permuted AdaIN network (ADPANet) based on a three-dimensional (3D) U-net architecture was developed to detect and localize the aortic annulus plane using cardiac CT. Patients (N = 72) who underwent TAVR between January 2017 and July 2020 at a tertiary medical center were enrolled. Ground truth using a limited dataset was delineated manually by three cardiac radiologists. Training, tuning, and testing sets (70:10:20) were used to build the deep learning model. The performance of ADPANet for detecting the aortic annulus plane was analyzed using the root mean square error (RMSE) and dice similarity coefficient (DSC). Results: In this study, the total dataset consisted of 72 selected scans from patients who underwent TAVR. The RMSE and DSC values for the aortic annulus plane using ADPANet were 55.078 ± 35.794 and 0.496 ± 0.217, respectively. Conclusion Our deep learning framework was feasible to detect the 3D complex structure of the aortic annulus plane using cardiac CT for TAVR. The performance of our algorithms was higher than other convolutional neural networks.
