Background/Aims:
To evaluate the associations between pediatric fatty liver severity, bioelectrical impedance analysis (BIA), and magnetic resonance imaging parameters, including total psoas muscle surface area (tPMSA) and paraspinal muscle fat (PMF).
Methods:
Children and adolescents who underwent BIA and liver magnetic resonance imaging between September 2022 and November 2023 were included. Linear regression analyses identified predictors of liver proton density fat fraction (PDFF) including BIA parameters, tPMSA, and PMF. Ordinal logistic regression analysis identified the association between these parameters and fatty liver grades. Pearson’s correlation coefficients were used to evaluate the relationships between tPMSA and muscle-related BIA parameters, and between PMF and fat-related BIA parameters.
Results:
Overall, 74 participants aged 8 to 16 years were included in the study. In the linear regression analyses, the percentage of body fat was positively associated with PDFF in all participants, whereas muscle-related BIA parameters were negatively associated with PDFF in participants with obesity. PMF and the PMF index were positively associated with PDFF in normalweight and overweight participants. In the ordinal logistic regression, percentage of body fat was positively associated with fatty liver grade in normal-weight and overweight participants and those with obesity, whereas muscle-related BIA parameters were negatively associated with fatty liver grade in participants with obesity. The PMF index was positively associated with fatty liver grade in normal/overweight participants. In the Pearson correlation analysis, muscle-related BIA parameters were correlated with tPMSA, and the fat-related BIA parameters were correlated with PMF.
Conclusions
BIA parameters and PMF are potential screening tools for assessing fatty liver in children.

Treatment for early colon cancer has progressed rapidly with endoscopic resection and minimally invasive surgery. Selection of patients without risk of lymph node metastasis is necessary before deciding on endoscopic resection for early colon cancer treatment. We aimed to review the optimal multidisciplinary treatment strategies for early colon cancer, including endoscopy and surgery.Current Concepts: Pathological risk factors include histologic grade of cancer cell differentiation, lymphovascular invasion, perineural invasion, tumor budding, and deep submucosal invasion. These risk factors for predicting lymph node metastasis are crucial for determining the treatment strategy of endoscopic excision and radical resection for early colon cancer. Prediction of the depth of invasion in early colon cancer using endoscopic optical assessments is vital to determine the appropriate treatment method for endoscopic or surgical resection. Furthermore, optical assessment of pit and vascular patterns is useful for estimating the depth of submucosal invasion using magnifying chromoendoscopy and narrow-band imaging endoscopy. Performing an endoscopic and pathologic evaluation of the risk factors for lymph node metastasis is imperative when selecting endoscopic or surgical resection. Endoscopic treatments include cold snare polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection. In addition, appropriate surgical treatment should be recommended for patients with early colon cancer with a high risk of lymph node metastasis.Discussion and Conclusion: A multidisciplinary approach should be recommended to establish an optimized treatment strategy, minimize the risk of complications, and obtain excellent oncologic outcomes via patienttailored treatment in patients with early colon cancer.
6.Association of Perfectionism with Job Search Behavior and Career Distress among Nursing Students in South Korea
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2022;31(1):27-35
Purpose:
Understanding the influence of perfectionism among senior nursing students is imperative for addressing strategies to reduce career distress and enhance job search behavior. The purpose of this study was to identify perfectionism types among senior nursing students in South Korea. Differences in career distress and enhanced job search behavior for each perfectionism type were compared.
Methods:
A cross-sectional, descriptive design was employed. A total of 211 nursing students completed surveys for Perfectionism, Job Search Behavior, and Career Distress. Cluster analysis and post-hoc tests were conducted.
Results:
A total of 80.1% were classified into the perfectionism group, including adaptive (49.8%) and maladaptive (30.3%). Maladaptive groups showed the highest discrepancy between standards and their perceived achievements as well as career distress. Job search behavior was the highest in the adaptive perfectionism group but the lowest in the non-perfectionism group.
Conclusion
Nursing educators should consider career coaching customized by each perfectionism type to improve job search behavior among nursing students.

Journal of Korean Geriatric Psychiatry 2022;26(2):59-69
Objective:
Mild cognitive impairment (MCI) is considered a pre-stage of dementia. This study aims to develop a cognitive intervention treatment program (CITP) as a non-pharmacological therapy, apply this program into MCI patients, and examine patients’ changes in cognitive function.
Methods:
Among 16 patients with MCI, 10 patients were randomly assigned to the experimental group and 6 patients were assigned into the control group. The patients assigned to the experimental group participated in the CITP once a week for a period of 15 weeks.The control group were suggested to live a normal daily life without CITP given. After 15 weeks (3 months), pre- and post-investigations, such as cognitive function test, emotional test, brain oxygen saturation test, were conducted and compared for each group.
Results:
The cognitive function scores and the brain oxygen saturation levels taken during the Verbal Fluency Test showed a sta-tistically significant difference between those of experimental and the control groups. To be specific, while the cognitive function score improved in the experimental group, there was a decline in the control group. There was no statistically significant difference in emo-tional changes between two groups. Looking at the changes within each group, the overall cognitive function score of the experimen-tal group was significantly increased, but no pre- and post-significantly changes were observed in brain oxygen saturation activation. On the other hand, the control group showed a statistically significant decline in the attention criteria of the cognitive functional ar-eas, and no statistically significant changed in brain activation.
Conclusion
The result from this study has given some promising views on maintaining and improving the deteriorating cognitive function in patients with MCI. Conducting CITP on patients is expected to strengthen the neural network. Eventually, there would be a less deterioration of cognitive function and less progression of MCI into dementia.

The variant terminal trunk of the superior mesenteric artery (SMA) could be confused with the ileocolic artery (ICA) as it runs on the right side of the superior mesenteric vein. If the variant ileal branch of SMA is mistaken for the ICA, unintentional ligation could cause long-segment ischemia in the ileum. We encountered a rare case of ileal ischemia caused by unintentional ligation of the variant ileal branch of the SMA during laparoscopic right hemicolectomy, which was confirmed by indocyanine green (ICG) angiography and hyperspectral imaging (HSI). Intraoperative real-time perfusion monitoring using ICG angiography and tissue oxygen saturation monitoring using HSI could help detect segments of hypoperfusion and prevent hypoperfusion-related anastomotic complications.

Kidney Research and Clinical Practice 2021;40(4):673-686
Background:
The clinical features of pediatric rhabdomyolysis differ from those of the adults with rhabdomyolysis; however, multicenter studies are lacking. This study aimed to investigate the characteristics of pediatric rhabdomyolysis and reveal the risk factors for acute kidney injury (AKI) in such cases.
Methods:
This retrospective study analyzed the medical records of children and adolescents diagnosed with rhabdomyolysis at 23 hospitals in South Korea between January 2007 and December 2016.
Results:
Among 880 patients, those aged 3 to 5 years old composed the largest subgroup (19.4%), and all age subgroups were predominantly male. The incidence of AKI was 11.3%. Neurological disorders (53%) and infection (44%) were the most common underlying disorder and cause of rhabdomyolysis, respectively. The median age at diagnosis in the AKI subgroup was older than that in the non-AKI subgroup (12.2 years vs. 8.0 years). There were no significant differences in body mass index, myalgia, dark-colored urine, or the number of causal factors between the two AKI-status subgroups. The multivariate logistic regression model indicated that the following factors were independently associated with AKI: multiorgan failure, presence of an underlying disorder, strong positive urine occult blood, increased aspartate aminotransferase and uric acid levels, and reduced calcium levels.
Conclusions
Our study revealed characteristic clinical and laboratory features of rhabdomyolysis in a Korean pediatric population and highlighted the risk factors for AKI in these cases. Our findings will contribute to a greater understanding of pediatric rhabdomyolysis and may enable early intervention against rhabdomyolysis-induced AKI.
