Background:
Low-density lipoprotein (LDL) cholesterol is a strong predictor of cardiovascular disease, resulting in the promotion of low-fat diets that emphasize the need to lower LDL cholesterol levels. We investigated the relationship between dietary carbohydrate intake and cardiovascular risk factors according to LDL cholesterol levels in Korean adults who typically consumed high-carbohydrate, low-fat diets.
Methods:
A total of 25,925 Korean adults were selected from the 2007-2015 Korea National Health and Nutrition Examination Surveys. Dietary carbohydrate intake was grouped into quintiles and cardiovascular risk factors included obesity, metabolic syndrome, type 2 diabetes, and dyslipidemia. Multiple logistic regression models were used to examine association between carbohydrate intake and cardiovascular risk factors by sex and LDL cholesterol levels.
Results:
Subjects with LDL cholesterol ≥130 mg/dL had significantly less energy and fat intake than those with LDL cholesterol <130 mg/dL both in men and women. In men, a higher carbohydrate intake was related to increased prevalence of atherogenic dyslipidemia and low high-density lipoprotein (HDL) cholesterol regardless of LDL cholesterol levels. Meanwhile, dietary carbohydrate intake was positively associated with low HDL cholesterol but inversely associated with hypercholesterolemia only in women with LDL cholesterol <130 mg/dL.
Conclusions
High carbohydrate intake in Korean adults is associated with low HDL cholesterol or atherogenic dyslipidemia regardless of LDL cholesterol levels. Carbohydrate intake should be carefully recommended according to the lipid profiles of individuals for the prevention and management of cardiovascular disease.

T cell receptor (TCR) signaling plays a critical role in T cell development, survival and differentiation. In the thymus, quantitative and/or qualitative differences in TCR signaling determine the fate of developing thymocytes and lead to positive and negative selection. Recently, it has been suggested that self-reactive T cells, escape from negative selection, should be suppressed in the periphery by regulatory T cells (Tregs) expressing Foxp3 transcription factor. Foxp3 is a master factor that is critical for not only development and survival but also suppressive activity of Treg. However, signals that determine Treg fate are not completely understood. The availability of mutant mice which harbor mutations in TCR signaling mediators will certainly allow to delineate signaling events that control intrathymic (natural) Treg (nTreg) development. Thus, we summarize the recent progress on the role of TCR signaling cascade components in nTreg development from the studies with murine model.

OBJECTIVE: Tributyltin (TBT), an endocrine disrupting chemical, has been reported to decrease ovarian function by causing apoptosis in the ovary, but the mechanism is not fully understood. Therefore, we examined whether TBT increases the expression of adipogenesis-related genes in the ovary and the increased expression of these genes is associated with apoptosis induction. METHODS: Three-week-old Sprague-Dawley rats were orally administered TBT (1 or 10 mg/kg body weight) or sesame oil as a control for 7 days. The ovaries were obtained and weighed on day 8, and then they were fixed for terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) or frozen for RNA extraction. Using the total RNA of the ovaries, adipogenesis- and apoptosis-related genes were analyzed by real-time polymerase chain reaction (PCR). RESULTS: The ovarian weight was significantly decreased in rats administered 10 mg/kg TBT compared to that in control rats. As determined by the TUNEL assay, the number of apoptotic follicles in ovary was significantly increased in rats administered 10 mg/kg TBT. The real-time PCR results showed that the expression of adipogenesis-related genes such as PPARgamma, aP2, CD36, and PEPCK was increased after TBT administration. In addition, apoptosis-related genes such as TNFalpha and TNFR1 were expressed more in the TBT-administered rats compared with the control rats. CONCLUSION: The present study demonstrates that TBT induces the expression of adipogenesis- and apoptosis-related genes in the ovary leading to apoptosis in the ovarian follicles. These results suggest that the increased expression of adipogenesis-related genes in the ovary by TBT exposure might induce apoptosis resulting in a loss of ovarian function.

Anti-myelin oligodendrocyte glycoprotein (anti-MOG) syndrome is an immunemediated inflammatory condition of the central nervous system, which usually involves spinal cord and optic nerves. Herein, we studied the case of a 57-yearold female patient who presented with acute/subacute symptoms of sphincter dysfunction, paraparesis, and ocular pain. The patient was diagnosed with anti-MOG syndrome with findings resembling snake-eye appearance (SEA), characterized by nearly symmetrical round high signal intensity lesions located at anterior horns (gray matter) on T2-weighted image.

PURPOSE: Although an Asian diet is typically high in carbohydrate and low in fat, there has been a steady increase in the rate of cardiometabolic disease in Asian countries over the past decade. We evaluated food patterns of a high-carbohydrate diet and examined their associations with metabolic disease. MATERIALS AND METHODS: Using data from the 2013–2015 Korean National Health and Nutrition Examination Survey, we included a total of 13106 subjects aged 20 years or older in this study. Diet was divided into seven groups according to the percentage of energy from carbohydrates. Food patterns were evaluated as individual servings per food group. Multivariate logistic regression was conducted to estimate odds ratios (OR) for metabolic disease. RESULTS: The proportions of men and women exceeding the recommended range of carbohydrate intake were 58.0% and 60.0%, respectively. A higher carbohydrate diet was associated with intake of low energy and saturated fats, with more grains and fruit, but less meat, fish, egg, bean (MFEB), and dairy consumption. Carbohydrate intake decreased by 3.0–3.4% per serving of MFEB and milk. In men, the highest carbohydrate group showed an OR of 1.35 [95% confidence interval (CI), 0.91 to 1.99] for metabolic syndrome, although this failed to show statistical significance. In women, the highest carbohydrate group had an OR of 1.38 (95% CI, 1.06 to 1.80) for a reduced level of high-density lipoprotein cholesterol. CONCLUSION: This study suggests that a very-high-carbohydrate diet for the Korean population is attributable to lower consumption of MFEB and dairy products and is associated with several metabolic risk factors. The appropriate distribution of macronutrients for the prevention and management of metabolic disease should be explored.

Purpose:
This systematic review and meta-analysis aimed to investigate the effectiveness of carbon ion radiotherapy (CIRT) compared to that of conventional radiotherapy in patients with various types of solid tumors.
Materials and Methods:
We systematically searched eight electronic databases from inception until August 2022 in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The comparative effectiveness of the different treatment options was assessed by a random-effects meta-analysis.
Results:
This review included 34 comparative studies and three treatment groups. Overall, the meta-analysis indicated comparable local control rates between the CIRT and control groups [pooled risk ratio (RR)=1.02, 95% confidence interval (CI) 0.90–1.15].The local control rate in the CIRT group was higher than that in the photon therapy group, but slightly lower than that in the proton radiation therpy (PRT) group. Additionally, the CIRT group had significantly higher overall survival (OS) (RR=1.19, 95% CI=1.01–1.42) and progression-free survival (PFS) (RR=1.50, 95% CI=1.01–2.21) rates compared to the control group. In the subgroup analysis, survival rates were similar between the CIRT and PRT groups.
Conclusion
CIRT was associated with improved toxicity, local tumor control, OS, and PFS compared to conventional treatments.Therefore, CIRT was found to be a safe and effective option for achieving local control in patients with solid tumors.
