Nowadays, it is hard to take enough sleep, so weekend catch-up sleep (CUS) may be an alternative option in modern society. To our knowledge, no previous studies reported the association between weekend CUS and metabolic syndrome, especially in the Korean population.Objective: We investigated the association between weekend CUS and the prevalence of metabolic syndrome in Korean adults (≥ 20 years old) with less than 6 hours of average weekday sleep.Patients and Methods: A total of 1,453 individuals were selected from the Korean National Health and Nutrition Examination Survey. Weekend CUS was divided into four categories: ≤ 0 hour, 0– 1 hour, 1– 2 hours, and ≥ 2 hours. Odds ratios (ORs) with 95% confidence intervals (CIs) were derived by univariate and multivariate logistic regression analyses.Results: Participants with weekend CUS ≥ 1 hour had decreased risk of metabolic syndrome in univariate analysis (CUS 1– 2 hours: OR: 0.413, 95% CI: 0.301– 0.568; CUS ≥ 2 hours: OR: 0.382, 95% CI 0.296– 0.493). Weekend CUS 1– 2 hours reduced the risk of metabolic syndrome in multivariate logistic regression analysis (OR: 0.552, 95% CI: 0.369– 0.823). Based on the age group analysis, weekend CUS ≥ 1 hour reduced the metabolic syndrome among those aged 20– 39 and 40– 65 (20– 39: CUS 1– 2 hours OR: 0.248, 95% CI: 0.078– 0.783, CUS ≥ 2 hours OR: 0.374, 95% CI: 0.141– 0.991; 40– 65: CUS 1– 2 hours OR: 0.507, 95% CI 0.309– 0.832 CUS ≥ 2 hours OR: 0.638, 95% CI: 0.415– 0.981).Conclusion: Weekend CUS was associated with a low risk of metabolic syndrome among Korean adults with sleep restriction.Keywords: sleep recovery, sleep deprivation, metabolic syndrome, insulin sensitivity

Atherosclerosis can be considered an important signal of CVD. Primary physicians can reduce the risk of CVD by preventing and treating obesity. Therefore, finding a tool to diagnose the association of obesity with arteriosclerosis is important. The association between obesity parameters and arterial stiffness remains controversial. To our knowledge, no previous studies reported the relationships between multiple new anthropometric parameters (a body shape index [ABSI], body round index [BRI], and visceral adiposity index [VAI]) and brachial-ankle wave velocity (ba-PWV) as an indicator of CVD risk, especially in the Korean population.Objective: To investigate the relationships between arterial stiffness (assessed using ba-PWV) and anthropometric parameters estimated on the basis of body mass index (BMI), waist circumference (WC), ABSI, BRI, and VAI, and to identify the indicators of obesity that best represents CVD risk.Methods: A total of 2,647 adults (1,474 men and 1,173 women) were recruited for this cross-sectional study. The correlations between the anthropometric indexes (BMI, WC, ABSI, BRI, and VAI) and mean ba-PWV were analyzed. Amultivariate linear regression analysis was performed to evaluate the association between each anthropometric and the presence of arterial stiffness.Results: We investigated the relationships between the obesity parameters and ba-PWV by adjusting the covariates (age, diabetes mellitus [DM], hypertension [HTN], and smoking status) related to the mean ba-PWV. In the multivariate regression analysis, ABSI (men: β =0.066, p

Elevated IOP is more frequently seen in the presence of metabolic disturbances that are associated with the components of metabolic syndrome (MetS). The aim of this study was to investigate the association between ocular hypertension and MetS.Patients and methods: We examined the relationship between ocular hypertension and MetS in 17,160 Korean adults without glaucoma aged >19 years (7,368 men and 9,792 women) who participated in the 2008–2010 Korea National Health and Nutrition Examination Survey. Multivariate logistic regression analysis was used to assess the relationship between MetS and ocular hypertension, after adjusting for age, body mass index, smoking, alcohol consumption, and regular exercise.Results: The prevalence of MetS was 35.1% among males and 30.1% among females. The prevalence of ocular hypertension was 1.3% among males with MetS and 0.7% among females with MetS. Participants with MetS had a significantly higher IOP than those without MetS (P≤0.001), and each component of MetS had a different effect on the IOP. Hypertension was the strongest predictor of an elevated IOP. In multivariate regression analysis, ocular hypertension was significantly associated with MetS (P=0.027 for men; P=0.015 for women).Conclusion: There is a statistically significant relationship between MetS and ocular hypertension.

Background: Colorectal cancer (CRC) is a malignant tumor of the large intestine. Studies have shown that the development and prognosis of CRC are associated with altered lipid metabolism. Niemann-Pick C1-Like 1 (NPC1L1), the target of ezetimibe, plays an essential role in the absorption of intestinal cholesterol. However, the role of altered NPC1L1 expression in the development and prognosis of CRC has not yet been determined.Methods: Datasets of patients with CRC were obtained from The Cancer Genome Atlas (TCGA) database. To compare the expression of NPC1L1 in normal and CRC tissues, datasets obtained from the GDAC platform were used. To support these results, we also analyzed other datasets from the Gene Expression Omnibus (GEO) database. Student’s t-test and chi-square test were used for the analyses. The log-rank test and multivariate Cox proportional hazards regression analysis were performed to determine whether NPC1L1 is a significant factor affecting the prognosis of CRC.Results: The mRNA expression of NPC1L1 was found to be upregulated in CRC, and was significantly associated with the N- and pathological stages, but not with the histological type, age, and sex. Moreover, an increase in NPC1L1 expression in CRC was associated with poorer survival, based on the Kaplan–Meier and multivariate regression analyses.Conclusions: High expression of NPC1L1 is associated with CRC development, pathological stage, and prognosis. The present study suggests that NPC1L1 represents a potential independent prognostic marker for CRC.
