ABSTRACT
A reduced estimated glomerular filtration rate (eGFR) is a predictor for mortality in patients with acute myocardial infarction (AMI). This study aimed to compare mortality according to the GFR and eGFR calculation methods during long-term clinical follow-ups. Using the Korean Acute Myocardial Infarction Registry-National Institutes of Health Data, 13,021 patients with AMI were included in this study. Patients were divided into the surviving (n=11,503, 88.3%) and deceased (n=1,518, 11.7%) groups.Clinical characteristics, cardiovascular risk factors, and 3-year mortality-related factors were analyzed. eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) equations. The surviving group was younger than the deceased group (62.6±12.4 vs. 73.6±10.5 years, p＜0.001), whereas the deceased group had higher hypertension and diabetes prevalences than the surviving group. A high Killip class was more frequently observed in the deceased group. eGFR was significantly lower in the deceased group (82.2±24.1 vs. 55.2±28.6 ml/min/1.73 m 2 , p＜0.001). Multivariate analysis revealed that low eGFR was an independent risk factor for mortality during the 3-year follow-up. The CKD-EPI equation was more useful for predicting mortality than the MDRD equation (0.766; 95% confidence interval [CI], 0.753-0.779 vs. 0.738; 95% CI, 0.724-0.753; p=0.001). Decreased renal function was a significant predictor of mortality after 3 years in patients with AMI. The CKD-EPI equation was more useful for predicting mortality than the MDRD equation.
ABSTRACT
Objectives@#This study aimed to evaluate the potential interaction between kidney function and the non-linear association between serum calcium levels and cardiovascular disease (CVD) mortality. @*Methods@#This study included 8927 participants enrolled in the Dong-gu Study. Albumin-corrected calcium levels were used and categorized into 6 percentile categories: 97.5th. Restricted cubic spline analysis was used to examine the non-linear association between calcium levels and CVD mortality. Cox proportional hazard regression was used to estimate hazard ratios (HRs) for CVD mortality according to serum calcium categories. All survival analyses were stratified by the estimated glomerular filtration rate. @*Results@#Over a follow-up period of 11.9±2.8 years, 1757 participants died, of whom 219 died from CVD. A U-shaped association between serum calcium and CVD mortality was found, and the association was more evident in the low kidney function group. Compared to the 25.0-50.0th percentile group for serum calcium levels, both low and high serum calcium tended to be associated with CVD mortality (97.5th: HR, 2.56; 95% CI, 0.76 to 8.66) in the low kidney function group. In the normal kidney function group, a similar association was found between serum calcium levels and CVD mortality (97.5th: HR, 1.65; 95% CI, 0.70 to 3.93). @*Conclusions@#We found a non-linear association between serum calcium levels and CVD mortality, suggesting that calcium dyshomeostasis may contribute to CVD mortality, and kidney function may modify the association.
ABSTRACT
Background and Objectives@#In previous studies, high homocysteine levels were associated with high cardiovascular mortality. However, these results were inconsistent with those of randomized controlled trials. We aimed to evaluate the causal role of homocysteine on allcause and cardiovascular mortality using Mendelian randomization (MR) analysis. @*Methods@#This study included the 10,005 participants in the Namwon Study. In conventional observational analysis, age, sex, survey years, lifestyles, body mass index, comorbidities, and serum folate level were adjusted using multivariate Cox proportional regression. MR using 2-stage least squares regression was used to evaluate the association between genetically predicted plasma homocysteine levels and mortality. Age, sex, and survey years were adjusted for each stage. The methylenetetrahydrofolate reductase (MTHFR) polymorphism was used as an instrumental variable for predicting plasma homocysteine levels. @*Results@#Observed homocysteine levels were positively associated with all-cause (hazard ratio [HR], 1.40; 95% confidence interval [CI], 1.26–1.54) and cardiovascular (HR, 1.62; 95% CI, 1.28–2.06) mortality when plasma homocysteine levels doubled. However, these associations were not significant in MR analysis. The HRs of doubling genetically predicted plasma homocysteine levels for all-cause and cardiovascular mortality were 0.99 (95% CI, 0.62–1.57) and 1.76 (95% CI, 0.54–5.77), respectively. @*Conclusions@#This MR analysis did not support a causal role for elevated plasma homocysteine concentrations in premature deaths.
ABSTRACT
Background and Objectives@#The association between bilirubin and atrial fibrillation (AF) has been evaluated previously in observational studies but with contradictory results. This study evaluated the causal association between serum bilirubin level and AF using Mendelian randomization (MR) analysis. @*Methods@#This cross-sectional study includes 8,977 participants from the Dong-gu Study.In the observational analysis, multivariate logistic regression was performed to evaluate the association between bilirubin and prevalent AF. To evaluate the causal association between bilirubin and AF, MR analysis was conducted by using the UGT1A1 rs11891311 and rs4148323 polymorphisms as instrumental variables. @*Results@#Elevated serum bilirubin levels were associated with an increased risk for AF in observational analysis (total bilirubin: odds ratio [OR], 1.31; 95% confidence interval [95% CI], 1.15–1.48 per 1 standard deviation [SD]; direct bilirubin: OR, 1.31; 95% CI, 1.18–1.46 per 1 SD), whereas the genetically predicted serum bilirubin levels in MR analysis did not show this association (total bilirubin: OR, 1.02; 95% CI, 0.67–1.53 per 1 SD; direct bilirubin: OR, 1.03; 95% CI, 0.61–1.73 per 1 SD). @*Conclusions@#Genetically predicted bilirubin levels were not associated with prevalent AF.Thus, the observational association between serum bilirubin levels and AF may be noncausal and affected by reverse causality or unmeasured confounding.
ABSTRACT
Purpose@#This study evaluated changes in growth and nutritional status using the first basic and the second repeated surveys on children from North Korean refugee families who settled in South Korea. @*Methods@#A total of 337 children were included in the survey. Using a structured questionnaire, the data collected included sex, date of birth, country of birth, date of entry to South Korea, and birth parents’nationality. The prevalence of stunting, underweight, wasting, and obesity were evaluated using the 2017 Korean National Growth Chart for Children and Adolescents. @*Results@#The prevalence of stunting decreased from 7.9% in the first survey to 6.9% in the second survey; that of underweight decreased from 6.0% to 4.7%; and that of wasting decreased from 6.3% to 3.5%; however, these changes were not statistically significant. The prevalence of obesity significantly increased from 8.0% to 13.2% in the first and second surveys, respectively (p=0.037). There was no significant difference in the prevalence of malnutrition according to the length of stay in South Korea or the children’s country of birth. However, the prevalence of obesity was significantly higher in children with longer lengths of stay and in those born in South Korea. @*Conclusion@#Although children from North Korean refugee families have settled in South Korea for a long time, the rate of malnutrition is still high, and the prevalence of obesity continuously increases.
ABSTRACT
Objectives@# This study aimed to investigate the nutritional status and dietary behavior of adolescents from North Korean refugee (NKR) families residing in South Korea (SK), who are known to be at a higher risk of malnutrition due to their lower socioeconomic status and facing other psychological challenges. @*Methods@# A total of 178 adolescents (91 males and 87 females) from NKR families were included in the analysis, and their demographic details such as age, birthplace, parental nationality, and duration of their settlement in SK were collected through questionnaires. Anthropometric measurements were also taken to determine their growth and nutritional status according to the 2017 Korean National Growth Charts for children and adolescents. The study used the Nutrition Quotient for Korean Adolescents (NQ-A) questionnaire to assess the dietary behavior of the participants. @*Results@# Approximately 11.8% and 10.1% of participants were identified with malnutrition and obesity, respectively. The total mean score for the NQ-A was 50.1. The mean scores for the individual factors of balance, diversity, moderation, environment, and practice were 49.2, 44.7, 43.8, 51.2, and 61.5, respectively. Approximately 47.2% of participants had a low NQA grade. However, there was no significant difference in the NQ-A scores according to their nutritional status or duration of time in SK. @*Conclusions@# Adolescents from NKR families exhibited both malnutrition and obesity.However, their dietary behavior, as assessed using the NQ-A, did not vary with their nutritional status. The unique challenges and related dietary behavior of North Korean adolescent refugees should be taken into consideration, when developing targeted strategies for nutritional education and health management programs.
ABSTRACT
Purpose@#This study aims to compare the growth and nutritional status of the children in North Korean Refugee (NKR) families and South Korean (SK) children. @*Methods@#This study examined 101 children of NKR families and 294 SK children. Researchers interviewed subjects using a standardized questionnaire and measured their height and weight. The nutritional status of children was estimated using the 2017 Korean National Growth Charts for children and adolescents using their weight. @*Results@#The children of NKR families were significantly shorter than the SK children (140.8±10.1 vs. 146.9±9.3, p<0.001) and weighed less (38.1±9.4 vs. 42.0±9.5, p<0.001). The prevalence of stunting and being underweight among children of NKR families was significantly higher than that of the SK children (stunting: 6.9% vs. 1.4%, p<0.001; underweight: 10.9% vs. 1.0%, p<0.001). However, there was no statistically significant difference in the prevalence of wasting and obesity. @*Conclusion@#Although children of NKR families have been living in SK for 4.4 years, their nutritional problems are more severe than those of SK children.
ABSTRACT
Background and Objectives@#Previous observational studies presented a positive association between alcohol and atrial fibrillation (AF). However, previous studies using genetic polymorphisms on the causal relationship between alcohol consumption and AF have reported conflicting results. This study aimed to evaluate the causality between alcohol consumption and AF using the aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism, which is the genetic variant with the most potent effect on drinking behavior. @*Methods@#A total of 8,964 participants from the Dong-gu Study were included in the present study. The causal association between alcohol consumption and AF was evaluated through a Mendelian randomization (MR) analysis using the ALDH2 rs671 polymorphism as an instrumental variable. @*Results@#No significant relationship between alcohol consumption and AF was found in the observational analysis. However, the genetic analysis using the ALDH2 polymorphism showed a significant association in men. In the MR analysis, genetically predicted daily alcohol consumption was positively related to AF. @*Conclusions@#MR analysis revealed a significant association between the amount of alcohol consumption and AF, which suggests that the association may be causal.
ABSTRACT
Purpose@#In this prospective study, we evaluated the association between the serum levels of antioxidants uric acid (UA), albumin, and total bilirubin and the risk of cancer in a Korean population. @*Materials and Methods@#A total of 15882 subjects were followed up for cancer development and cancer-related death. During the follow-up period, 1619 cancer diagnoses and 617 cancer-related deaths were recorded. Cox proportional regression was performed to calculate the hazard ratio (HR) per standard deviation (SD) increment and 95% confidence interval (CI). The model was adjusted for covariates such as the age, sex, smoking, alcohol consumption, physical activity, education level, body mass index, and family history. Sensitivity analyses using the study subjects with physiological serum levels of each indicator were also performed. @*Results@#UA levels were positively correlated with cancer risk (HR per SD increment 1.04; 95% CI, 1.01–1.09), and albumin levels were inversely associated with the overall cancer risk (HR, 0.92; 95% CI, 0.88–0.96) and cancer-related death (HR, 0.86; 95% CI, 0.80–0.93). Total bilirubin levels were negatively correlated with the risk of cancer-related death (HR, 0.91; 95% CI, 0.83–0.99). By cancer type, UA was positively associated with prostate cancer, total bilirubin was positively associated with liver cancer, and albumin was inversely associated with lung cancer. @*Conclusion@#The findings of this study support the role of antioxidants in carcinogenesis. Future large-cohort studies are needed to confirm the predictive value of albumin, UA, and total bilirubin levels in each type of cancer.
ABSTRACT
Background@#Several studies have reported conflicting results regarding the relationship between alcohol consumption and cortisol levels. However, the causality between alcohol consumption and cortisol levels has not been evaluated. @*Methods@#This study examined 8,922 participants from the Dong-gu Study. The aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism was used as an instrumental variable for alcohol consumption. The association between the genetically predicted alcohol consumption and cortisol level was evaluated with Mendelian randomization (MR) using two-stage least squares regression. @*Results@#Alcohol consumption was positively associated with the serum cortisol level in both sexes in the observational analysis. In the MR analysis, the genetically predicted alcohol consumption was positively related to the cortisol level in men, with cortisol levels increasing by 0.18 µg/dL per drink per day. However, there was no relationship in women in the MR analysis. @*Conclusion@#The predicted alcohol consumption according to the ALDH2 rs671 polymorphism was positively related to the cortisol levels, suggesting a causal relationship between alcohol consumption and cortisol levels.

ABSTRACT
Cell labeling technologies are required to monitor the fate of transplanted cells in vivo and to select target cells for the observation of certain changes in vitro. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have been transplanted for the treatment of heart injuries or used in vitro for preclinical cardiac safety assessments. Cardiomyocyte (CM) labeling has been used in these processes to facilitate target cell monitoring. However, the functional effect of the labeling agent on hiPSC-CMs has not been studied. Therefore, we investigated the effects of labeling agents on CM cellular functions. 3’-Dioctadecyloxacarbocyanine perchlorate (DiO), quantum dots (QDs), and a DNA plasmid expressing EGFP using Lipo2K were used to label hiPSC-CMs. We conclude that the hiPSC-CM labeling with DiO and QDs does not induce arrhythmogenic effects but rather improves the mRNA expression of cardiac ion channels and Ca2＋ influx by L-type Ca2＋ channels. Thus, DiO and QD labeling agents may be useful tools to monitor transplanted CMs, and further in vivo influences of the labeling agents should be investigated in the future.
ABSTRACT
BACKGROUND: Elevated blood pressure is a major preventable cause of cardiovascular diseases. Alcohol consumption is a well-known risk factor of elevated blood pressure. The aldehyde dehydrogenase 2 (ALDH2) polymorphism is common in Eastern Asians, and inactive ALDH2 genotypes are associated with both avoiding alcohol consumption and aldehyde accumulation. Therefore, this study assessed the associations between alcohol consumption and hypertension and blood pressure according to the ALDH2 genotypes.METHODS: This study consists of 8,526 participants in the Dong-gu Study. Multivariate logistic regression was used to calculate the odds ratio (OR) according to alcohol consumption after stratifying by gender and ALDH2 genotypes. Multivariate linear regression was performed to estimate the systolic blood pressure (SBP) and diastolic blood pressure (DBP) according to the amount of alcohol consumed.RESULTS: In men, alcohol consumption was positively associated with both SBP and DBP in active ALDH2 carriers, but not in inactive ALDH2 carriers. In active ALDH2 carriers, compared to non-drinkers, the OR of hypertension was 1.16 (95% confidence interval [CI], 0.91–1.49) for < 1 drink/day, and 1.44 (95% CI, 1.15–1.80) for ≥ 1 drink/day in men. With each 1 drink/day increase, SBP and DBP increased by 3 and 1 mmHg in men, respectively. There was no significant association between ALDH2 genotypes and hypertension and blood pressure in women.CONCLUSION: ALDH2 genotype modified the association between alcohol consumption and blood pressure in men. There was a positive relationship between alcohol consumption and blood pressure in active ALDH2 carriers, but no significant relationship in inactive ALDH2 carriers.

ABSTRACT
BACKGROUND: Apolipoprotein E (APOE) gene polymorphism is associated with neurodegenerative and cardiovascular diseases. Although the effects of the gene differ by ethnic group, few studies have examined Asians. Therefore, the association between APOE polymorphism and mortality in Koreans was evaluated in this study. METHODS: This study population included participants from the Dong-gu and Namwon Studies. APOE genotypes were categorized as E2 (E2/E2 and E2/E3), E3 (E3/E3), and E4 (E3/E4 and E4/E4). Multivariate Cox proportional hazard models were constructed using the E3 allele as a reference. RESULTS: In the model adjusting for study site, age, gender, and lifestyle, the hazard ratio (HR) of mortality for those with the E4 allele was 1.08 (95% confidence interval [CI], 0.97–1.20), while that for those with the E2 allele was 0.84 (95% CI, 0.74–0.96). After adjusting for blood lipids to evaluate their mediating effects, the HRs of mortality for those with E4 and E2 alleles were 1.08 (95% CI, 0.97–1.20) and 0.80 (95% CI, 0.70–0.92), respectively. These associations were more evident in younger groups, with HRs of 0.70 (95% CI, 0.52–0.92) for the E2 allele and 1.25 (95% CI, 1.03–1.53) for the E4 allele. CONCLUSION: In two large population-based cohort studies, the E2 allele was associated with a lower risk of mortality compared with the E3 allele, whereas the E4 genotype was not associated with mortality in Koreans.

BACKGROUND: As of July 2015, per diem payment was changed from fee for service Therefore, this study aims to analyse changes in medical charges and medical services before and after enforcement of the palliative care, targeting palliative care wards in a general hospital, and provide basic data needed for development of per diem payment. METHODS: The subjects of the study were a total of 610 cases consisting of 351 patients of service fee who left hospital (died) from July 2014 to June 2016 and 259 ones of per diem payment at Chosun University Hospital in Gwangju Metropolitan City. RESULTS: The results are summarized as follows. First, after the palliative care system was applied, benefit medical service charges and insurance increased significantly (p<0.001). As benefit medical service charges increased, benefit private insurance payment increased significantly (p<0.001). Second, after the per diem payment was applied, total private insurance payment to medical institutes decreased significantly (p=0.050) and non-benefit also decreased significantly (p=0.001). CONCLUSION: It is suggested that additional rewards in the obligatory palliative care items should be continuously remedied and monitored to provide good quality hospice palliative care.
