Purpose: Several studies have been conducted on the relationship between green tea intake and metabolic syndrome. However, compared to the studies carried out internationally, there is inadequate research on the relationship between domestic green tea consumption and metabolic syndrome. Therefore, in this study, the general characteristics of Koreans according to their green tea intake and its association with metabolic syndrome were examined. Methods: A total of 44,611 subjects were included in the study, and analysis was carried out using data from the Korean Genome and Epidemiology Study (KoGES) for Korean adults aged 40 or older. Green tea consumption was estimated using 106 verified food frequency questionnaires (FFQ). Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) parameters. After adjusting for confounding variables by performing a Cox regression analysis, the association between green tea consumption and metabolic syndrome was confirmed through the hazard ratio (HR) and 95% confidence interval (CI). Results: The average incidence of metabolic syndrome was 18.7% (20.8% in men and 17.8% in women). Compared to those who drank almost no green tea, in subject groups consuming more than one cup of green tea a day, the metabolic syndrome incidence was significantly reduced by 15% (HR, 0.85; 95% CI, 0.74–0.96; p trend = 0.0200) among men and by 19% (HR, 0.81; 95% CI, 0.73–0.90; p trend < 0.0001) among women. In addition, the biomarkers related to metabolic syndrome also tended to decrease overall in these groups. Conclusion This study concluded that as the intake of green tea increased, the incidence of metabolic syndrome and related indicators decreased. Therefore, green tea intake is believed to have a positive effect on the prevention and management of the metabolic syndrome.

Purpose: The 2020 Dietary Reference Intakes for Koreans (KDRIs) serves as a foundation for daily nutrient and energy recommendations aiming to enhance public health and prevent chronic diseases. They act as guidelines for maintaining proper nutrition and overall health.Using KDRIs is crucial for promoting healthier lifestyles and making informed dietary choices. Thus, this study explores the influence of a nutrition education program, based on the 2020 KDRIs, on the nutrition knowledge and dietary habits of undergraduates in Gyeongsangnam-do and Gyeonggi-do. Methods: The nutrition education program, designed with diverse instructional materials, was executed across a wide range of universities. The education group (n = 75) engaged in the program for a 6-week instructional period, while the control group (n = 53) underwent the survey without participating in the education program. Nutrition Quotient (NQ) and knowledge assessments were administered to both groups immediately before and after the instructional period. Results: Within the education group, the nutrition education program positively impacted responses to NQ practice items, including knowledge of nutrition, daily intake, and portion sizes (p < 0.05). In contrast, there were no significant differences between the before and after responses of the control group for most survey items. Post-program evaluations showed significantly higher self-assessment scores and increased satisfaction levels (p < 0.05), with the satisfaction rate for the education program using the 2020 KDRIs reaching 99.2%. Conclusion This study has demonstrated the positive impact of an effective nutrition education program. However, there is a need for the continuous development and implementation of nutrition education programs to sustain these outcomes and further enhance the nutritional education experience.

Due to rapid westernization, Korean dietary habits have emerged as significant risk factors for chronic disease and cancer. Despite this transition, Korea’s cancer prevention guidelines have remained consistent since their establishment about 18 years ago. This study aimed to investigate the degree of awareness and practice to global dietary guidelines among Korean adults and identify demographic and lifestyle factors associated with low practice. A cross-sectional survey conducted in 2023 included 4,000 adults and assessed their awareness and practice of four global recommendations: “Eat a diet rich in whole grains,” “Limit consumption of processed meat,” “Limit consumption of sugar-sweetened beverages,” and “Limit consumption of fast and other processed foods.” While more than half of the participants recognized the guidelines’ importance for cancer prevention, implementation rates remained below 40%. Furthermore, over 80% of the respondents expressed a compelling requirement for updated and tailored dietary guidelines. Younger individuals, those who were physically inactive, individuals who had not received prior nutrition education, and participants with obesity were more likely to exhibit low practice, particularly to guidelines limiting processed foods and sugary beverages intake. These findings highlight the need to revise Korea’s cancer prevention recommendations by incorporating global dietary practices and addressing the westernized eating patterns prevalent within the population. Efforts should focus on promoting these updated guidelines through targeted education and public health interventions that improve practice, especially in high-risk groups, and effectively mitigate the burden of diet-related cancers in Korea.

OBJECTIVE: This study aimed to develop a nomogram that predicts ongoing pregnancy after in vitro fertilization and embryo transfer (IVF-ET) using patient age and serum hormonal markers. METHODS: A total of 284 IVF-ET cycles were retrospectively analyzed. At 14 days post-oocyte pick-up (OPU), the serum human chorionic gonadotropin (HCG) and progesterone levels were measured. The main predicted outcome was ongoing pregnancy. RESULTS: Patient age and serum of HCG and progesterone levels at 14 days post-OPU were good predictors of ongoing pregnancy. The cut-off value and area under the curve (AUC) (95% confidence interval) were 36.5 years and 0.666 (0.599–0.733), respectively, for patient age; 67.8 mIU/mL and 0.969 (0.951–0.987), respectively, for serum HCG level; and 29.8 ng/mL and 0.883 (0.840–0.925), respectively, for serum progesterone level. When the prediction model was constructed using these three parameters, the addition of serum progesterone level to the prediction model did not increase its overall predictability. Furthermore, a high linear co-relationship was found between serum HCG and progesterone levels. Therefore, we developed a new nomogram using patient age and HCG serum level only. The AUC of the newly developed nomogram for predicting ongoing pregnancy after IVF-ET cycles using patient age and serum HCG level was as high as 0.975. CONCLUSION: We showed that ongoing pregnancy may be predicted using only patient age and HCG serum level. Our nomogram could help clinicians and patients predict ongoing pregnancy after IVF-ET if the serum JCG level was ≥5 IU/L at 14 days post-OPU.

Background: Detection of anti-human leukocyte antigen (HLA) antibodies is important during the selection of an appropriate donor prior to organ transplantation and also for monitoring the patients after transplantation. In this study, we compared antibodies detected via C3d assays, which monitors C3d complement-binding activities of HLA antibodies with those detected via single antigen bead (SAB) assays. Methods: A total of 66 serum samples were tested in parallel by SAB assays (Immucor Transplant Diagnostics, USA) and C3d assays (Immucor) for the detection of HLA class II antibodies. The relationship between these two methods was analyzed based on the types, numbers, median fluorescent intensity (MFI) values, and positivity of the antibodies using MATCH IT! Antibody (Immucor) program. Results: The number of antibodies obtained based on SAB and C3d assays was the highest with 24 samples (36.4%) in the 11–20 range and 23 (34.8%) in the 2–5 range detected via each assay. Among the SAB-positive antibodies, only 28 (6.4%) of the 440 antibodies with MFI ≤3,000 were C3d-positive, and 341 (61.3%) of the 556 antibodies with MFI ≥3,001 were C3d-positive. Whereas, among the 442 C3d-positive antibodies, SAB assays were positive except for 32 (7.2%) and 41 (9.3%) antibodies in the sections of MFI ≤500 and 1,001 ≤MFI ≤10,000, respectively. C3d-positive samples had higher maximum MFI values based on SAB assays, compared with C3d-negative samples. Conclusions MFI values of HLA class II antibodies detected through SAB assays in C3d-positive samples were higher than those in C3d-negative samples.
