1.A Study on the Characteristics of Nutrient Intake in Metabolic Syndrome Subjects.
The Korean Journal of Nutrition 2008;41(6):510-517
This study was conducted to investigate the prevalence of metabolic syndrome (MS) and characteristics of nutrient intake in MS subjects by gender and age. The subjects were 957 (447 men and 510 women) who visited medical center for regular medical check-up. The diagnosis of MS subjects was adapted from NCEP-ATPIII with blood glucose, cholesterol, triglycerides, and blood pressure and Aisa-Pacific definition with waist-circumference. Anthropometric and biochemical measurements were practiced, then the nutrient intake analysis was assessed through the 24-hour recall method. The MS prevalence of all subjects was 10.3% in average -17% in men and 4.5% in women, respectively. The energy intake in MS group was 2047.1 kcal and 1699.5 kcal for normal group, showing significantly higher in MS compared to normal subjects. For intakes of animal fat, cholesterol, and sodium, MS group were significantly higher than normal group. In respect of gender, men subjects of MS group showed significantly higher nutrient intakes than normal group for energy, fat, and cholesterol. Women subjects of MS group showed higher intakes for energy, carbohydrate, and protein. For 30s, MS group showed higher intakes of energy, animal fat, and cholesterol than normal group. Fat and cholesterol for 40s and energy, carbohydrate, vegetable fat for 50s, MS group showed significantly higher intakes than normal group. In summary, MS group showed higher intakes of energy, animal fat, cholesterol, and sodium than normal group.

One important purpose of premedical education is to help students attain core competencies during the two-year premedical program. Since premedical curriculum is the foundation of medical education, it is necessary to develop the premedical curriculum in accordance with the overarching curriculum of a medical school. Inje University's College of Medicine (IUCM) has attempted to integrate competency-based medical education into the premedical education curriculum. The revised premedical curriculum aims to develop students' intrinsic competencies during premedical years. In an effort to do so, IUCM defined competencies for premedical education, analyzed and designed premedical courses according to the defined competencies, and suggested learner-centered instructional methods. As a result of implementing the revised premedical curriculum, students have reported both positive experiences and difficulties. Based on the results, it will be necessary to continuously improve the premedical curriculum as well as develop appropriate methods for evaluating student achievement of the defined competencies.

Objective:
The purpose of this study was to assess whether a deep learning (DL) algorithm could enable simultaneous noise reduction and edge sharpening in low-dose lumbar spine CT.
Materials and Methods:
This retrospective study included 52 patients (26 male and 26 female; median age, 60.5 years) who had undergone CT-guided lumbar bone biopsy between October 2015 and April 2020. Initial 100-mAs survey images and 50-mAs intraprocedural images were reconstructed by filtered back projection. Denoising was performed using a vendor-agnostic DL model (ClariCT.AI TM , ClariPI) for the 50-mAS images, and the 50-mAs, denoised 50-mAs, and 100-mAs CT images were compared. Noise, signal-to-noise ratio (SNR), and edge rise distance (ERD) for image sharpness were measured. The data were summarized as the mean ± standard deviation for these parameters. Two musculoskeletal radiologists assessed the visibility of the normal anatomical structures.
Results:
Noise was lower in the denoised 50-mAs images (36.38 ± 7.03 Hounsfield unit [HU]) than the 50-mAs (93.33 ± 25.36 HU) and 100-mAs (63.33 ± 16.09 HU) images (p < 0.001). The SNRs for the images in descending order were as follows: denoised 50-mAs (1.46 ± 0.54), 100-mAs (0.99 ± 0.34), and 50-mAs (0.58 ± 0.18) images (p < 0.001). The denoised 50-mAs images had better edge sharpness than the 100-mAs images at the vertebral body (ERD; 0.94 ± 0.2 mm vs. 1.05 ± 0.24 mm, p = 0.036) and the psoas (ERD; 0.42 ± 0.09 mm vs. 0.50 ± 0.12 mm, p = 0.002). The denoised 50-mAs images significantly improved the visualization of the normal anatomical structures (p < 0.001).
Conclusion
DL-based reconstruction may enable simultaneous noise reduction and improvement in image quality with the preservation of edge sharpness on low-dose lumbar spine CT. Investigations on further radiation dose reduction and the clinical applicability of this technique are warranted.

OBJECTIVES: The survival rate of all childhood cancers has been increasing, and latent effects on childhood cancer survivors have been gaining researchers' attention. It has been shown that childhood cancer survivors experience social maladaptation and a decreased quality of life. Although neuroblastoma is one of the most common solid cancers in childhood, there are few reports on psychosocial status in neuroblastoma survivors. The purpose of this study was to investigate temporal changes in psychosocial status in neuroblastoma survivors. METHODS: This study was conducted by undertaking retrospective chart reviews of neuroblastoma survivors that were treated between January 1997 and February 2016 at Samsung Medical Center, Seoul, Korea. Among the 54 survivors identified, data for 28 patients who underwent psychological evaluation before and after treatment completion were selected for further analysis. We compared intelligence score, Korea-Child Behavior Checklist (K-CBCL), and Korean Personality Rating Scale for Children (K-PRC) scores before and after treatment completion. Time derivatives for each variable were calculated to identify temporal changes in scores. RESULTS: After treatment completion, K-CBCL scores for total competence (t=−2.34, p=0.044), somatic complaints (t=−2.43, p=0.022), and thought problems (t=−3.03, p=0.006) were higher than the scores prior to treatment. Familial relationship in K-PRC was significantly improved after treatment (t=2.11, p=0.045). Time derivatives of the significant K-CBCL subscales, except for the withdrawal and externalizing symptom scores, showed a tendency to increase with time. CONCLUSION: Although familial relationship and social competence improved after treatment, the levels of somatic complaints and thought problems increased following neuroblastoma treatment.

OBJECTIVES:
This study evaluated the incidence of colorectal cancer (CRC) according to the number of metabolic syndrome (MetS) components.
METHODS:
Using health checkup and insurance claims data of 6,365,409 subjects, the occurrence of CRC according to stage of MetS by sex was determined from the date of the health checkup in 2009 until December 31, 2018.
RESULTS:
Cumulative incidence rates (CIR) of CRC in men and women was 3.9 and 2.8 per 1000 (p < 0.001), respectively. CIR of CRC for the normal, pre-MetS, and MetS groups in men was 2.6, 3.9, and 5.5 per 1000 (p < 0.001) and CIR in women was 2.1, 2.9, and 4.5 per 1000 (p < 0.001), respectively. Compared with the normal group, the hazard ratio (HR) of CRC for the pre-MetS group was 1.25 (95% CI 1.17-1.33) in men and 1.09 (95% CI 1.02-1.17) in women, and the HR of CRC for the MetS group was 1.54 (95% CI 1.43-1.65) in men and 1.39 (95% CI 1.26-1.53) in women after adjustment.
CONCLUSIONS
We found that MetS is a risk factor for CRC in this study. Therefore, the prevention and active management of MetS would contribute to the prevention of CRC.
