Association between BDNF Polymorphism and Depressive Symptoms in Patients Newly Diagnosed with Type 2 Diabetes Mellitus

Purpose@#Little is known about the relationship between brain-derived neurotrophic factor (BDNF) gene polymorphisms and psychiatric symptoms in diabetes patients. We investigated the effects of BDNF Val/66/Met polymorphism, glucose status, psychological susceptibility, and resilience on anxiety and depression symptoms in patients newly diagnosed with type 2 diabetes mellitus (T2DM). @*Materials and Methods@#We examined biochemical factors and BDNF polymorphism in 89 patients who were newly diagnosed with T2DM. Psychiatric symptoms were investigated with the Hospital Anxiety and Depression Scale (HADS), and the ConnorDavidson Resilience Scale (CD-RISC) and Impact of Event Scale (IES) were used to assess psychological resilience and susceptibility to psychological distress, respectively. Logistic regression analyses were conducted to investigate factors associated with psychiatric symptoms. @*Results@#We determined that 62 patients (70%) were Met-carriers. No significant differences were found between the Val/Val homozygous and Met-carrier groups regarding age, sex, body mass index, and clinical factors related to glycemic control and lipid profiles. HADS-anxiety and HADS-depression scores and IES factor scores were higher in the Met-carrier than the Val/Val homozygous group. Hemoglobin A1c (HbA1c) level was significantly inversely correlated with the severity of depressive symptoms. Resilience factors showed significant inverse correlations, and IES factors showed positive correlations with depressive symptom severity. In the logistic regression analysis model, depressive symptoms were significantly associated with HbA1c and BDNF polymorphism, whereas only the hyperarousal factor of the IES scale was associated with anxiety. @*Conclusion@#Depressive symptoms are associated with the presence of the Met-carriers and lower HbA1c in patients newly diagnosed with T2DM.

Development of the Battery Test for Screening of Depression and Mental Health: PROtective and Vulnerable factors battEry Test (PROVE) / 신경정신의학

Objectives@#This study developed a battery test that allows a comprehensive evaluation of depressive symptoms and related protective-vulnerable factors to screen for depression and mental health and examined the reliability and validity of the test. @*Methods@#PROtective and Vulnerable factors battEry test (PROVE) consisting of five sub-sections was developed: depressive symptomatology (PROVE-DS), suicide risk (PROVE-SR), and three protective-vulnerable factors, which were adult attachment type (PROVE-ATT), adverse childhood experience (PROVE-ACE), and mentalization capacity (PROVE-MC). Two hundred and thirteen subjects completed the PROVE test and other comparative scales, and the analysis was carried out based on the data. @*Results@#The PROVE test showed good convergent, discriminant, and concurrent validity as well as adequate internal consistency. In addition, five sub-sections of the PROVE test showed significant relevance to each other. @*Conclusion@#The results of this study indicate that the PROVE test is a reliable and valid test, which will be useful for the prevention, evaluation, and treatment of depression in various clinical settings.

Reclassification of BRCA1 and BRCA2variants found in ovarian epithelial, fallopian tube, and primary peritoneal cancers / 부인종양

Objective@#We investigated the proportions of and reclassified BRCA1/2 variants of unknown significance (VUS) in Korean patients with epithelial ovarian, tubal, and primary peritoneal cancers. @*Methods@#Data from 805 patients who underwent genetic testing for BRCA1/2 from January 1, 2006 to August 31, 2018 were included. The VUS in BRCA1/2 were reclassified using the 2015 American College of Medical Genetics and Genomics and the Association for Molecular Pathology standards and guidelines. @*Results@#A BRCA1 pathogenic variant was found in 17.0% (137/805) of the patients, and BRCA1 VUS were found in 15.9% (128/805) of the patients. Further, 8.7% (69/805) of the patients possessed a BRCA2 pathogenic variant and 18.4% (148/805) of the patients possessed BRCA2 VUS. Fifty-three specific BRCA1 VUS were found and 20 were further reclassified as benign (n=11), likely benign (n=5), likely pathogenic (n=3), and pathogenic (n=1). The remaining 33 remained classified as VUS. For BRCA2, 55 specific VUS were detected; among these, 14 were reclassified as benign or likely benign, and 2 were reclassified as likely pathogenic. Among the 805 patients, 195 were found to have only VUS and no pathogenic variants (PV), and 41.5% (81/195) were reclassified as benign or likely benign, and 10.3% (20/195) as pathogenic or likely pathogenic variants. @*Conclusions@#Approximately 33.3% (36/108) of the specific BRCA1/2 variants analyzed in this study that were initially classified as VUS over a 13-year period were reclassified. Among these, 5.6% (6/108) were reclassified as pathogenic or likely pathogenic variants.

Preliminary Findings on the Effectiveness of Meaning-Centered Psychotherapy in Patients with Pancreatobiliary Cancer

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