RESUMEN
Background: Insulin resistance contributes to the development of cardiovascular disease and type 2 diabetes mellitus. Smoking leads to an increase in triglyceride levels, which, in turn, increases insulin resistance. Although the number of e-cigarette users has increased in recent years, few studies have investigated the association between ecigarette use and insulin resistance. Therefore, this study aimed to determine the association between e-cigarette use and insulin resistance using the triglyceride-glucose (TyG) index in Korean adults. Methods: This study included 4,404 healthy adults aged ≥20 years who participated in the Korea National Health and Nutrition Examination Survey between 2019 and 2020. Participants were categorized as never-smokers or ecigarette users, and the TyG index was categorized into low- and high-TyG index groups according to the median value (9.22). A logistic regression analysis was performed to determine the association between e-cigarette smoking and insulin resistance. Results: E-cigarette users had a higher TyG index than never smokers (e-cigarette: mean=3.95; never: mean=9.18; P<0.001). The e-cigarette users had a higher risk of being in the high TyG index group than never-smokers (odds ratio [OR], 1.38; 95% confidence interval [CI], 1.03-1.84). In the subgroup analysis stratified by sex, age, and body mass index, a higher OR for a high TyG index was observed in men (OR, 1.46; 95% CI, 1.03-2.08) and individuals aged 60 years or older (OR, 3.74; 95% CI, 1.14-12.30). Conclusion: Our findings suggest that e-cigarette use is significantly associated with insulin resistance.
RESUMEN
Elevated uric acid levels are linked with obesity and diabetes. Existing research mainly examines the relationship between sugar-sweetened carbonated beverage (SSB) consumption and uric acid levels. This study explored the association between the quantity and frequency of SSB consumption and elevated uric acid levels in Korean adults. Data from 2881 participants aged 19-64 years (1066 men and 1815 women) in the 2016 Korea National Health and Nutrition Examination Survey were analyzed. Serum uric acid levels were categorized into quartiles, with the highest defined as high uric acid (men, ≥6.7 mg/dL; women, ≥4.8 mg/dL). SSB consumption was classified into quartiles (almost never, <1 cup (<200 mL), 1-3 cups (200-600 mL), ≥3 cups (≥600 mL)) and frequency into tertiles (almost never, ≤1/week, ≥2/week). Multivariate logistic regression assessed the association, with separate analyses for men and women. Increased daily SSB consumption and frequency were significantly associated with high uric acid levels in men but not in women. After adjusting for sociodemographic and health characteristics, consuming ≥3 cups (≥600 mL) of SSBs per day and SSBs ≥ 2/week were significantly associated with high serum uric acid levels in men, but this association was not observed in women. The study concludes that increased SSB intake is linked to elevated uric acid levels in Korean men, but not in women.

Background: Skipping breakfast is associated with an increased risk of chronic inflammatory diseases. This study aimed to examine the association between breakfast-eating habits and inflammation, using high-sensitivity C-reactive protein (hs-CRP) as a marker. Methods: A total of 4,000 Korean adult males with no history of myocardial infarction, angina, stroke, diabetes, rheumatoid arthritis, cancer, or current smoking were included. Data from the 2016-2018 Korea National Health and Nutrition Examination Survey were used for analysis. The frequency of breakfast consumption was assessed through a questionnaire item in the dietary survey section asking participants about their weekly breakfast consumption routines over the past year. Participants were categorized into two groups, namely "0-2 breakfasts per week" and "3-7 breakfasts per week"; hs-CRP concentrations were measured through blood tests. Results: Comparing between the "infrequent breakfast consumption (0-2 breakfasts per week)" and "frequent breakfast consumption (3-7 breakfasts per week)" groups, the mean hs-CRP was found to be significantly higher in the "infrequent breakfast consumption" group, even after adjusting for age, body mass index, physical activity, alcohol consumption, systolic blood pressure, blood pressure medication, fasting blood glucose, and triglycerides (mean hs-CRP: frequent breakfast consumption, 1.36±0.09 mg/L; infrequent breakfast consumption, 1.17±0.05 mg/L; P-value=0.036). Conclusion: Less frequent breakfast consumption was associated with elevated hs-CRP levels. Further large-scale studies incorporating adjusted measures of daily eating patterns as well as food quality and quantity are required for a deeper understanding of the role of breakfast in the primary prevention of chronic inflammatory diseases.

RESUMEN
Background: Sarcopenia is defined as the loss of muscle mass and strength and low physical performance, and it is closely related to the risk of cardiovascular disease and mortality. Pulse pressure (PP) is a biomarker of arterial stiffness and compliance. Elevated PP levels increase the risk of cardiovascular diseases and all-cause mortality. Nevertheless, the association between PP and sarcopenia has not yet been clearly established. Methods: Participant data were extracted from the Korea National Health and Nutrition Examination Survey conducted from 2014 to 2020. The study population was classified into three groups (PP < 40 mmHg, 40 mmHg ≤ PP < 60 mmHg, and PP ≥ 60 mmHg). PP was calculated by deducting the diastolic blood pressure from the systolic blood pressure. For handgrip strength, the maximum value measured with a grip dynamometer was adopted (weak handgrip strength: <28 kg for men, <18 kg for woman; normal handgrip strength: ≥28 kg for men, ≥18 kg for women). To determine the relationship between PP and the prevalence of weak handgrip strength, multiple logistic regression analysis was performed after adjusting for possible confounding factors. Results: The higher PP group had a higher age, body mass index; systolic blood pressure, prevalence of hypertension, diabetes, hyperlipidemia, and metabolic syndrome, and maximum handgrip strength. In all models, the prevalence of weak handgrip strength was significantly higher in the group with PP ≥ 60 mmHg compared to the control group (PP < 40 mmHg). Conclusions: Elevated PP was significantly associated with a higher prevalence of weak muscle strength. Thus, PP monitoring may be used to identify individuals at risk of sarcopenia and is helpful in improving health outcomes.
RESUMEN
OBJECTIVE: Menarche and menopause are associated with muscle loss and strength in women. Handgrip strength (HGS) is a reliable measurement method of muscle strength. However, it is unclear whether the entire reproductive period, which encompasses both menarche and menopause, is associated with HGS in postmenopausal women. METHODS: A total of 2,354 postmenopausal women aged 45-75 years were included for statistical analysis. The reproductive period was divided into tertiles, and HGS was divided into four quartiles. HGS was measured to evaluate muscle strength. Binary logistic regression analysis was used to identify significant predictors with the first quartile HGS, derived from quartile data. Multiple logistic regression analysis was used to assess the relationship between the reproductive period (exposure) and low HGS (outcome). RESULTS: We found that the more extended the reproductive period, the lower the risk of low absolute HGS. This trend persisted even after controlling for other variables. Specifically, the odds ratio for low absolute HGS was 0.752 (95% confidence interval [CI], 0.563-1.000) for the second tertile reproductive period and 0.683 (95% CI, 0.513-0.900) for the third tertile reproductive period, with the first tertile reproductive period as the reference. The odds ratio for low relative HGS was 0.761 (95% CI, 0.551-1.052) for the second tertile reproductive period and 0.732 (95% CI, 0.533-0.972) for the third tertile reproductive period, using first tertile reproductive period as the reference, after covariate adjustment. CONCLUSIONS: A longer reproductive period is associated with a decreased risk of low HGS in postmenopausal women.

Background and Objectives: Lipid-lowering agents such as ezetimibe are recommended in uncontrolled hyperlipidemia for primary and secondary prevention of cardiovascular disease. Carotid intima-media thickness (CIMT) is a surrogate marker of atherosclerosis and a predictor of cardiovascular and cerebral events. The effects of ezetimibe on CIMT have been inconsistently reported. The aim of this meta-analysis is to compare the effects of ezetimibe/statin and statin alone therapies on CIMT reduction. Materials and Methods: The PubMed, Embase, and Cochrane library databases were searched for randomized controlled trials (RCTs) published prior to 26 January 2023 with the MeSH keywords 'Ezetimibe' and 'Carotid Intima-Media Thickness'. The results were presented as standard mean difference (SMD) with 95% confidence intervals using the random-effect model method, and heterogeneity was assessed. Subgroup, meta-regression, and sensitivity analyses were conducted. Results: Five RCTs with 642 participants were included. CIMT reduction was not significantly different between the ezetimibe/statin and statin alone groups. However, in subgroup analyses, CIMT in the ezetimibe/statin group was significantly reduced in patients with non-familial hypercholesterolemia (SMD: -0.34 mm and p = 0.002) and in patients with secondary prevention (SMD: -0.38 mm and p = 0.002). The low-density lipoprotein cholesterol level was significantly reduced in the ezetimibe/statin group (SMD: -0.58 mg/dL and p < 0.001). Conclusions: The effect of ezetimibe on CIMT reduction was shown in non-familial hypercholesterolemia and secondary prevention. These results suggest that the efficacy of ezetimibe may vary with potential CIMT reduction benefits in certain subpopulations.

Purpose: For the dignity of patients nearing the end of their lives, it is essential to provide end-of-life (EoL) care in a separate, dedicated space. This study investigated the utilization of specialized rooms for dying patients within a hospice unit. Methods: This retrospective study examined patients who died in a single hospice unit between January 1, 2017, and December 31, 2021. Utilizing medical records, we analyzed the circumstances surrounding death, the employment of specialized rooms for terminally ill patients, and the characteristics of those who received EoL care in a shared room. Results: During the 1,825-day survey period, deaths occurred on 632 days, and 799 patients died. Of these patients, 496 (62.1%) received EoL care in a dedicated room. The average duration of using this dedicated space was 1.08 days. Meanwhile, 188 patients (23.5%) died in a shared room. Logistic regression analysis revealed that a longer stay in the hospice unit was associated with a lower risk of receiving EoL care in a shared room (odds ratio [OR]=0.98, 95% confidence interval [CI] 0.97~0.99; P=0.002). Furthermore, a higher number of deaths on the day a patient died was associated with a greater risk of receiving EoL care in a shared room (OR=1.66, 95% CI 1.33~2.08; P<0.001). Conclusion: To ensure that more patients receive EoL care for an adequate duration in a private setting, additional research is necessary to increase the number of dedicated rooms and incorporate them into the hospice unit at an early stage.
RESUMEN
Metabolic and bariatric surgery (MBS) is an effective treatment for patients with morbid obesity and its comorbidities. However, many patients experience weight regain (WR) after achieving their nadir weight. Establishing the definition of WR is challenging as postoperative WR has various definitions. Risk factors for WR after MBS include anatomical, racial, hormonal, metabolic, behavioral, and psychological factors, and evaluating such factors preoperatively is necessary. Long-term regular follow-up and timely treatment by a multidisciplinary team are important because WR after surgery is multi-factorial. Although lifestyle interventions that focus on appropriate dietary education, physical activity education or interventions, and behavioral psychological interventions are suggested, more well-designed studies are needed because studies evaluating intervention methods and the effectiveness of WR prevention are lacking. Anti-obesity drugs can be used to prevent and manage patients with WR after MBS; however, more research is needed to determine the timing, duration, and type of anti-obesity drugs used to prevent WR.
RESUMEN
OBJECTIVE: Hyperuricemia is associated with metabolic and cardiovascular diseases and mortality. Efforts to lower the risk of hyperuricemia in various ways are needed as the prevalence of these diseases increases in postmenopausal women. Studies have shown that one of these methods is associated with adequate sleep duration, which is related to a low risk of hyperuricemia. Considering that it is difficult for people to get enough sleep in modern society, this study hypothesized that weekend catch-up sleep could be an alternative. To our knowledge, no past study has investigated the relation between weekend catch-up sleep and hyperuricemia in postmenopausal women. Hence, the aim of this research was to estimate the relation between weekend catch-up sleep and hyperuricemia with insufficient sleep in postmenopausal women during weekday or workday. METHODS: This study included 1,877 participants extracted from the Korea National Health and Nutrition Examination Survey VII. The study population was divided into weekend catch-up sleep and non-weekend catch-up sleep groups. Odds ratios with 95% confidence intervals were derived using multiple logistic regression analysis. RESULTS: Weekend catch-up sleep had a significantly lower prevalence of hyperuricemia after adjusting for confounders (odds ratio, 0.758 [95% confidence interval, 0.576-0.997]). In a subgroup analysis, weekend catch-up sleep of 1 to 2 hours was significantly correlated with a lower prevalence of hyperuricemia after adjusting for confounders (odds ratio: 0.522 [95% confidence interval, 0.323-0.845]). CONCLUSIONS: Weekend catch-up sleep had a decreased prevalence of hyperuricemia in postmenopausal women with sleep deprivation.

BACKGROUND: Sleep duration is associated with hearing loss, especially presbycusis, which is the most common type of hearing loss; however, there is limited evidence regarding this association among the Korean population. We aimed to determine the relationship between sleep duration and high-frequency hearing loss in Korean adults aged ≥40 years. METHODS: We examined 5,547 Korean adults aged ≥40 years who completed audiometric tests and questionnaires regarding sleep duration during the 2010-2012 cycle of the Korea National Health and Nutrition Examination Survey. Mild presbycusis was defined as >25 decibels (dB) and <40 dB, whereas moderate-to-severe presbycusis was defined as >40 dB pure tone averages at high frequencies (3,000, 4,000, and 6,000 Hz) for both ears. Additionally, the sleep duration was divided into quartiles. Odds ratios and 95% confidence intervals were estimated using multivariable logistic regression after adjusting for covariates. RESULTS: The prevalence of presbycusis in South Korean adults was 62.1%, of which 61.4% showed moderate to severe presbycusis. The incidence of moderate-to-severe, but not mild, presbycusis showed a significant positive correlation with sleep duration. CONCLUSION: Our findings suggest that sleep duration is associated with the prevalence of presbycusis.
RESUMEN
Sarcopenia is characterized by a loss of muscle mass and strength and is associated with a high risk of cardiovascular events and increased mortality. Pulse pressure (PP) serves as a marker for changes in heart structure and function, as well as arterial stiffness. A high PP also increases the risk of cardiovascular disease and all-cause mortality. However, the relationship between PP and sarcopenia is poorly understood. We used the data of participants of the Korea National Health and Nutrition Examination Survey (KNHANES) of 2008 to 2011. Participants were divided into a control group (PPâ <â 40 mm Hg) and a high-PP group (PPâ ≥â 40 mm Hg). PP was calculated by subtracting the diastolic blood pressure (DBP) from the systolic blood pressure (SBP), and the low muscle index was assessed using appendicular skeletal muscle mass (ASM) normalized by body mass index (BMI). Multiple logistic regression analyses were performed to examine the association between PP and the prevalence of low muscle mass, adjusting for potential confounders. The high-PP group had a higher age, SBP, DBP, and prevalence of hypertension, diabetes and hyperlipidemia than the control group. The high-PP group had a higher prevalence of low muscle mass than the control group in all models. A high PP is significantly associated with a higher prevalence of low muscle mass. Therefore, PP monitoring may help identify individuals at risk of sarcopenia and guide interventions to improve health outcomes.

Metabolic syndrome (MetS) is a global health challenge characterized as a group of risk factors for developing atherosclerotic cardiovascular disease. Although visceral adipose tissue, adipocyte dysfunction, chronic low-grade inflammation, and insulin resistance are fundamental to MetS, the exact biochemical mechanisms underlying this disease state remain unclear. Numerous biomarkers, however, have been proposed to improve our understanding of its complex pathophysiology and facilitate diagnosis. This review examines these biomarkers and clarifies their potential roles in the pathogenesis, diagnosis, prediction, progression, and severity of MetS and MetS-related disorders.

BACKGROUND: Folic acid is involved in inflammatory reactions; however, the association between folic acid and allergic diseases, particularly asthma, remains unclear. Thus, this study aimed to evaluate the association between serum folic acid levels and asthma in Koreans. METHODS: This study analyzed the serum folic acid levels of 6,615 individuals included in the 2016-2018 Korea National Health and Nutrition Examination Survey. The prevalence of asthma was determined using a questionnaire that identified cases of physician-diagnosed asthma. The relationship between serum folic acid levels and asthma was analyzed using logistic regression analysis. RESULTS: Multiple logistic regression analysis showed that a 1 ng/mL increase in serum folic acid level significantly reduced the risk of asthma after adjusting for confounding factors including sex, age, household income, current smoking, current alcohol use, and body mass index (odds ratio [OR], 0.930; 95% confidence interval [CI], 0.876- 0.987; P=0.017). The relationship between the adjusted odds of asthma and serum folic acid levels were consistently inverse (OR, 2.266; 95% CI, 1.126-4.420; P for trend=0.038). CONCLUSION: Serum folic acid levels are inversely associated with physician-diagnosed asthma in the Korean population.
RESUMEN
AIM: This study aimed to investigate the distribution of foot conditions, the risk of foot ulceration and its associated factors in patients with diabetes. Few studies have focused on the risk of foot ulceration in patients with diabetes. METHODS: A total of 267 patients with diabetes who attended outpatient clinics in two tertiary referral hospitals were recruited from June to September 2016. The risk of foot ulceration was classified using the American Diabetes Association (ADA), International Working Group on the Diabetic Foot (IWGDF) and Scottish Intercollegiate Guidelines Network (SIGN) classification systems. The risk categories of each system were reclassified into high- (categories of 2 and 3 for the ADA and IWGDF systems and high for the SIGN system) and low-risk. RESULTS: Foot deformity was the most prevalent condition (38.2%). Among 261 patients without active ulcers, between 17.6% to 35.2% were classified in the high-risk group and overall agreement among systems ranged from .42 to .56 of the kappa statistic. Insulin treatment was consistently associated with a high-risk of foot ulceration. CONCLUSIONS: As the risk varies between systems, nurses should select a suitable classification system through validation studies and assess the risk in patients with diabetes, particularly, those receiving insulin treatment.

BACKGROUND: The aim of this study was to evaluate the association between near work time and depression. METHODS: Data of 1,551 workers aged 19-49 years from the sixth Korea National Health and Nutrition Examination Survey were examined. The Patient Health Questionaire-9 scores were used to screen for depression. Participants who scored a total of 10 or above, which is suggestive of the presence of depression, were classified as the depression group; the rest were classified as normal. The correlation between daily near work time and depression was analyzed using multivariate logistic analysis after adjusting for other sociodemographic and health behavior-related variables. RESULTS: Multivariate logistic analysis found that workers with 3 or more hours of near work were more likely to report depression compared to the reference group who had 2 or fewer hours per day of near work (adjusted odds ratio, 2.471; 95% confidence interval, 1.062-5.747). CONCLUSION: Longer near work time was associated with depression among South Korea's workers. Therefore, it is necessary to reduce near work time to prevent depression.
RESUMEN
BACKGROUND: Colorectal cancer (CRC) is a malignancy of the large intestine, whose development and prognosis have been demonstrated to be associated with altered lipid metabolism. High cholesterol intake is associated with an increased risk of CRC, and elevated serum cholesterol levels are known to be correlated with risk of developing CRC. Niemann-Pick C1-Like 1 (NPC1L1), a target of ezetimibe, plays an essential role in the absorption of intestinal cholesterol. However, whether the altered expression of NPC1L1 affects CRC development and prognosis is currently unknown. METHODS: Data corresponding to patients with CRC were obtained from The Cancer Genome Atlas (TCAG). Datasets from the Genome Data Analysis Center (GDAC) platform were analyzed to compare the expression of NPC1L1 in normal and CRC tissues using the Mann-Whitney U test and chi-square test. Further, the datasets from the Gene Expression Omnibus (GEO) database were analyzed. The log-rank test and multivariate Cox proportional hazard regression analysis were performed to determine whether NPC1L1 significantly affects the prognosis of CRC. RESULTS: The 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. Increased NPC1L1 expression in CRC was related to poor patient survival, as evidenced by the Kaplan-Meier and multivariate regression analyses. CONCLUSIONS: As high expression of NPC1L1 was associated with CRC development, pathological stage, and prognosis, NPC1L1 can serve as an independent prognostic marker for CRC.

Background: Metabolic syndrome (MetS) is a major cause of increased cardiovascular disease mortality in middle-aged men. Previous studies examined the birth season and health status such as obesity and cardiovascular mortality in adulthood. However, the relationship between birth season and MetS has not yet been studied. In this study, we examined the prevalence of MetS in middle-aged men according to birth season. Materials and Methods: In this cross-sectional study, the data were collected from 4575 middle-aged men 30-50 years of age, who underwent a comprehensive health checkup examination. The subjects were separated into four seasons according to birth month. Results: There were no statistically significant differences in age according to birth season. However, there was a significant difference in the prevalence of MetS according to birth season: it was highest in spring (25.9%) and lowest in autumn (21.7%, odds ratio [OR] 0.787, 95% confidence interval [CI] 0.646-0.960, P = 0.001). Middle-aged men born in the spring had the highest body mass index (BMI) and prevalence of high waist circumference (WC), high fasting plasma glucose (FPG), and high blood pressure (BP), while those born in autumn had the lowest BMI (η2 = 0.007, P = 0.001) and prevalence of high WC (OR = 0.664, 95% CI 0.558-0.790, P = 0001), high FPG (OR = 0.761, 95% CI 0.624-0.928, P = 0.03), and high BP (OR = 0.633, 95% CI 0.531-0.755, P = 0.001). The prevalence of MetS according to birth months was highest in March (26.8%) and lowest in July (18.6%, OR 0.629, 95% CI 0.444-0.980, P = 0.001). Conclusion: Middle-aged men born in the spring had a higher prevalence of MetS than those born in the fall.

BACKGROUND: Predicting how long a patient with far advanced cancer has to live is a significant part of hospice and palliative care. Various prognostic models have been developed, but have not been fully compared in South Korea. OBJECTIVES: We aimed to compare the accuracy of the Prognosis in Palliative Care Study (PiPS), Palliative Prognostic Index (PPI), Palliative Prognostic Score (PaP) and Objective Prognostic Score (OPS) for patients with far advanced cancer in a palliative care unit in South Korea. METHODS: This prospective study included patients with far advanced cancer who were admitted to a single palliative care unit at the National University Hospital. Variables for calculating the prognostic models were recorded by a palliative care physician. The survival rate was estimated using the Kaplan-Meier method. The sensitivity, specificity, positive predictive value and negative predictive value of each model were calculated. RESULTS: A total of 160 patients participated. There was a significant difference in survival rates across all groups, each categorised through the five prognostic models. The overall accuracy (OA) of the prognostic models ranged between 54.5% and 77.6%. The OA of clinicians' predictions of survival ranged between 61.9% and 81.3%. CONCLUSION: The PiPS, PPI, PaP and OPS were successfully validated in a palliative care unit of South Korea. There was no difference in accuracy between the prognostic models, and OA tended to be lower than in previous studies.
RESUMEN
OBJECTIVE: The objective of this study is to evaluate irritable bowel syndrome (IBS) as a risk factor for osteoporosis and osteoporotic fracture in Korean women after controlling for basic confounding factors and considering detailed demographic and clinical information. SUBJECTS AND METHODS: We performed a nationwide population-based retrospective cohort analysis and matched every IBS case with a non-IBS case at a 1:4 frequency ratio based on age. The population consisted of female patients with data in the Health Insurance Review and Assessment (HIRA) database from 2002 to 2010. To determine the risk of osteoporosis and osteoporotic fracture in IBS and non-IBS patients, hazard ratios (HRs) with 95% confidence intervals (CI) were estimated using Cox proportional hazards regression models, adjusting for confounding variables, such as the area of residence, health insurance type, and economic status. RESULTS: We identified 1,017,468 patients in the HIRA database with data from 2002 to 2010 who could potentially be included in the cohort. Among these, we identified 1,545 (11.4%) women (age >19 years) with newly diagnosed IBS (IBS group). Additionally, 6,180 patients without IBS and age-matched to the IBS group were selected. Cox modeling revealed that the crude HRs for osteoporosis and osteoporotic fractures in patients with IBS were 1.476 (95% CI, 1.241-1.754) and 1.427 (95% CI, 1.086-1.876), respectively. CONCLUSION: Our data showed an increased incidence of osteoporosis and osteoporotic fractures in women with IBS compared with age-matched controls.
