Objective: Neuroinflammation’s role is increasingly emphasized in the pathology of major depressive disorder (MDD), and its close association with the risk of suicide is being reported. The Forkhead Box O1 (FoxO1) gene is known to play a role in regulating mood and emotion and is associated with susceptibility to suicidality in relation to environmental stress. This research aims to explore the relationship between FoxO1 and the risk of suicide in individuals with MDD. Methods: We enrolled 127 healthy controls (HC) and 231 patients diagnosed with MDD, including 119 individuals with high suicide risk (HSR). All participants underwent the Hamilton Rating Scale for Depression Assessment and magnetic resonance imaging. Cortical thickness and white matter integrity were evaluated. Results: In the HSR group, cortical thinning was observed in the left triangular part of the inferior frontal gyrus and right transverse frontopolar gyrus compared to HC. Additionally, fractional anisotropy (FA) values were decreased in the left posterior thalamic radiation, sagittal stratum, and uncinate fasciculus. Although no differences were observed based on allele variations for the two FoxO1 single nucleotide polymorphisms (SNPs), those with the minor allele of FoxO1 rs34733279, especially in the HSR group, displayed increased cortical thinning and reduced FA values in the left cingulum. Conclusion Our study reveals close association between the minor allele of the FoxO1 gene rs34733279 and suicide risk in the left cingulum highlights the potential key role of the FoxO1 gene rs34733279 in the context of suicidal vulnerability. Further investigations are warranted to elucidate the underlying biological mechanisms.

Background: Melanoma arising from the scalp is rare and often diagnosed at advanced stages due to difficulty in detection. Objective: This is the first study that aimed to analyze the clinicopathological findings of scalp melanoma among Korean patients at a single institution. Methods: In this single-centered retrospective study, medical records were used to review data of patients with scalp melanoma between 2006 to 2021. Chronic sun damage (CSD) was evaluated by reviewing histopathological findings of scalp melanoma. Results: Fifteen patients were identified. Mean age at diagnosis was 53.93 years. In 14 cases, the tumors were located on hair-covered areas. Mean Breslow’s thickness was 6.06 mm. Nodular melanoma was the most common histologic type (n=9), followed by superficial spreading (n=5), and lentigo maligna (n=1). Ulceration was present in five cases. In nine cases, CSD was moderate. Elective neck node dissection was performed in 13 cases, with five revealing nodal involvement. At initial staging, three patients were in stage I, six were in stage II, four were in stage III, and two were in stage IV. Recurrence occurred in seven of the 15 cases. There were five confirmed mortalities during a mean follow-up period of 35 months. Conclusion In this study, the Breslow’s thickness of scalp melanoma was relatively deep, and the most frequent type was nodular melanoma. Since detection can be affected by black hair among Koreans, it may result in delayed diagnosis and poor prognosis. Therefore, more caution is needed when examining suspicious lesions on the scalp.

PURPOSE: ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is the standard imaging modality for response evaluation in FDG-avid lymphoma, but the prognostic value is not established in follicular lymphoma (FL). This study investigated the prognostic value of Deauville 5-point scale (D5PS) from paired interim PET/CT (PET(Interim)) and end-of-induction therapy PET/CT (PET(EOI)) in patients with FL.METHODS: FL staging and response assessment PET/CT images from 2013 to 2015 were retrospectively reviewed. PET(Interim) was performed 3 or 4 cycles after chemotherapy and PET(EOI) after 6 or 8 cycles. D5PS scores of 1, 2, and 3 were considered as negative (−), and scores 4 and 5 were considered as positive (+). Statistical analysis was done using Cox regression analysis, Kaplan-Meier survival analysis, and the log-rank test.RESULTS: Thirty-three patients with set of baseline, interim, and end-of-induction therapy PET/CTstudies were included. Ten patients (30.3%) had progression. The median progression-free survival (PFS) was 38.8 months (range 3.5–72.7 months). On PET(Interim), 23 patients were negative and 10 were positive. On PET(EOI) scans, 29 patients were negative, and 4 were positive. On multivariate analysis, PET(EOI)(−) was associated with longer PFS. PET(Interim)(+) and PET(EOI)(+) patients had a significantly shorter PFS than PET(Interim)(−) patients (39.9 months, 95%confidence interval [CI] 23.0–56.9, versus 55.5months, 95%CI 49.7–61.2, p=0.005) and PET(EOI)(−) patients (14.2 months, 95% CI 8.5–19.8, versus 60.5 months, 95% CI 52.1–69.0, p<0.001).CONCLUSION: For patients with FL, PET(Interim) and PET(EOI) response is predictive of PFS, and PET(EOI)(+) is an independent prognostic factor for progression of FL.

PURPOSE: Melanoma is a highly heterogeneous neoplasm, composed of subpopulations of tumor cells with distinct molecular and biological phenotypes and genotypes. In this study, to determine the genetic heterogeneity between primary and metastatic melanoma in Korean melanoma patients, we evaluated several well-known genetic alterations of melanoma. In addition, to elucidate the clinical relevance of each genetic alteration and heterogeneity between primary and metastatic lesions, clinical features and patient outcome were collected. MATERIALS AND METHODS: In addition to clinical data, BRAF, NRAS, GNAQ/11 mutation and KIT amplification data was acquired from an archived primary Korean melanoma cohort (KMC) of 188 patients. Among these patients, 43 patients were included for investigation of tumor heterogeneity between primary melanoma and its corresponding metastatic lesions. RESULTS: Overall incidence of genetic aberrations of the primary melanomas in KMC was 17.6% of BRAF V600, 12.6% of NRAS mutation, and 28.6% of KIT amplification. GNAQ/11 mutation was seen in 66.6% of the uveal melanoma patients. Patients with BRAF mutation were associated with advanced stage and correlated to poor prognosis (p < 0.01). Among 43 patients, 55.8% showed heterogeneity between primary and metastatic lesion. The frequency of BRAF mutation and KIT amplification significantly increased in the metastatic lesions compared to primary melanomas. GNAQ/11 mutation showed 100% homogeneity in uveal melanoma patients. CONCLUSION: Our data demonstrated heterogeneity between primary melanomas and corresponding metastatic lesions for BRAF, NRAS mutation and KIT amplification. However, GNAQ/11 mutation was genetically homogeneous between primary and metastatic melanoma lesions in uveal melanoma.

OBJECTIVE: To evaluate the effect of hospital-based cardiac rehabilitation (CR) on quality of life (QOL) and physical ability in patients with myocardial infarction (MI). METHODS: Patients with MI who were referred to the Cardiac Health and Rehabilitation Center 2 weeks after percutaneous coronary intervention were divided into CR and non-CR groups. The CR group performed supervised exercises 3 times a week for 2 months. QOL assessment, using the 36-item Short-Form Health Survey (SF-36) and physical ability evaluation were performed at the beginning and end of CR. RESULTS: The CR group demonstrated statistically significant improvements in physical functioning (PF), physical role functioning (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social role functioning (SF), emotional role functioning (RE), mental health (MH), physical component summary (PCS), and mental component summary (MCS). The non-CR group showed improvement in RP. Secondary outcomes, including resting heart rate (RHR), maximal oxygen consumption (VO(2max)), metabolic equivalent of task (MET), maximal exercise time (ET(max)), stage 3 Borg rating of perceived exertion (3RPE), maximal Borg rating of perceived exertion (RPEmax), and stage 3 rate pressure product (3RPP), improved in the CR group. The non-CR group showed improvements in VO(2max), MET, ET(max), and 3RPE. There were significant differences in improvements in PF, RP, BP, VT, SF, MH, MCS, RHR, VO(2max), MET, ET(max), 3RPE, and 3RPP between the two groups. CONCLUSION: Male patients with MI demonstrated improvements in QOL and physical ability following hospital-based CR; the impact on the mental component was greater than that on the physical component.
