RESUMEN
OBJECTIVES: This study evaluated the incidence of colorectal cancer (CRC) according to the number of metabolic syndrome (MetS) components. METHODS: Using health checkup and insurance claims data of 6,365,409 subjects, the occurrence of CRC according to stage of MetS by sex was determined from the date of the health checkup in 2009 until December 31, 2018. RESULTS: Cumulative incidence rates (CIR) of CRC in men and women was 3.9 and 2.8 per 1000 (p < 0.001), respectively. CIR of CRC for the normal, pre-MetS, and MetS groups in men was 2.6, 3.9, and 5.5 per 1000 (p < 0.001) and CIR in women was 2.1, 2.9, and 4.5 per 1000 (p < 0.001), respectively. Compared with the normal group, the hazard ratio (HR) of CRC for the pre-MetS group was 1.25 (95% CI 1.17-1.33) in men and 1.09 (95% CI 1.02-1.17) in women, and the HR of CRC for the MetS group was 1.54 (95% CI 1.43-1.65) in men and 1.39 (95% CI 1.26-1.53) in women after adjustment. CONCLUSIONS: We found that MetS is a risk factor for CRC in this study. Therefore, the prevention and active management of MetS would contribute to the prevention of CRC.

BACKGROUND: Patients undergoing liver transplantation (LT) are prone to dialysis-requiring acute kidney injury (AKI-D). However, long-term prognoses among them need further investigation, as overall survival after LT is improving. METHODS: A nationwide, population-based cohort study was conducted using the data of Korean National Health Insurance System between 2006 and 2015. The patients who received dialysis during the perioperative period of LT were in the AKI-D group, and the control group included those who did not undergo dialysis. RESULTS: Among the 6879 patients who underwent LT, 968 were in the AKI-D group. All-cause mortality [adjusted hazard ratio (HR): 1.52 (1.26-1.83), P < 0.001], end-stage renal disease (ESRD) progression [adjusted HR: 2.93 (2.34-3.66), P < 0.001], and ICU readmission [adjusted HR: 1.70 (1.44-2.01), P < 0.001] within and after 90 days from discharge were increased in the AKI-D group. When analyzed among those who recovered from dialysis at discharge, overall outcomes were similar to those of the AKI-D group, except the long-term mortality. CONCLUSIONS: AKI-D during the perioperative period of LT was associated with worse mortality, ESRD progression, and ICU readmission risk. The results of renal-recovered patients could indicate clinicians that achievement of dialysis independence is important to gain favorable long-term postdischarge survival.

OBJECTIVES: Long-term risk of a major adverse cardiovascular events in ICU survivors who underwent acute renal replacement therapy requires further investigation. DESIGN: Nationwide population-based study using the claims database of Korea. SETTING: Index admission cases of ICU survivors in government-designated tertiary hospitals PATIENTS:: The study group consisted of ICU survivors who underwent acute renal replacement therapy, and the control group consisted of those without acute renal replacement therapy. Patients were excluded if they 1) were under age 20, 2) expired within 30 days after discharge, 3) received ICU care for less than 24 hours, 4) had a previous ICU admission, 5) had a history of major adverse cardiovascular event, or 6) had a major adverse cardiovascular event-related cardio/cerebrovascular diseases. The outcomes of the patients who received continuous renal replacement therapy were compared with those of patients who received only intermittent renal replacement therapy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Information regarding patient characteristics and treatment modalities was collected and adjusted. The main outcome was major adverse cardiovascular event, including acute myocardial infarction, revascularization, and acute ischemic stroke. Patient mortality and progression to end-stage renal disease were also evaluated. We included 12,380 acute renal replacement therapy patients and 382,018 patients in the control group. Among the study group, 6,891 patients were included in the continuous renal replacement therapy group, and 5,034 in the intermittent renal replacement therapy group. The risks of major adverse cardiovascular event (adjusted hazard ratio, 1.463 [1.323-1.619]; p < 0.001), all-cause mortality (adjusted hazard ratio, 1.323 [1.256-1.393]; p < 0.001), and end-stage renal disease (adjusted hazard ratio, 18.110 [15.779-20.786]; p < 0.001) were higher in the acute renal replacement therapy patients than the control group. When we compared the continuous renal replacement therapy patients with the intermittent renal replacement therapy patients, the risk of major adverse cardiovascular event was comparable (adjusted hazard ratio, 1.049 [0.888-1.239]; p = 0.575). CONCLUSIONS: Clinicians should note the increased risk of a long-term major adverse cardiovascular event in acute renal replacement therapy patients and consider appropriate risk factor management. Significant difference in the risk of postdischarge major adverse cardiovascular event was not identified between continuous renal replacement therapy and intermittent renal replacement therapy.

Background: To evaluate the association between metabolic syndrome (MetS) and the incidence of dementia using big data from national health claims and health examinations. Methods: This study involved 3,619,388 subjects categorized with MetS of three status based on the results of health examinations conducted in 2009. This was a longitudinal study of the incidence of dementia based on the national health claims from the date of health examinations in 2009 until December 31, 2018. This study was conducted for men and women aged 50 to 69 years living in Korea. A Cox proportional hazard regression was performed to analyze the risk of dementia according to the status of MetS. Results: The cumulative incidence of Alzheimer dementia was 0.41% in the non-Mets group, 0.54% in the pre-MetS group, and 0.67% in the MetS group. The cumulative incidence of vascular dementia was 0.19% in the non-Mets group, 0.27% in the pre-MetS group, and 0.34% in the MetS group. The risk of Alzheimer dementia in the pre-MetS group compared to the non-Mets group was 1.20-fold greater (95% confidence interval, CI: 1.14-1.26) and was 1.39-fold (95% CI: 1.31-1.48) greater in the MetS group. The risk of vascular dementia in the pre-MetS group compared to the non-Mets group was 1.30-fold greater (95% CI: 1.21-1.40) and the risk of vascular dementia was 1.53-fold (95% CI: 1.44 1.71) greater. Conclusions: This study showed that pre-MetS and MetS were related to an increased incidence of Alzheimer dementia and vascular dementia. Also, these results support efforts to decrease the incidence of Alzheimer dementia and vascular dementia through managing the Mets.

PURPOSE: This study was conducted to investigate the trend in functional changes over time and factors associated with the number of areas showing functional decline in older adults who had been discharged from acute care hospitals. METHODS: This longitudinal study involved 156 patients aged ≥ 65 years who were admitted to one tertiary hospital in Seoul and discharged home. Authors investigated patient demographic and health-care characteristics and the number of areas showing functional decline at 1 and 3 months after discharge. The data were analyzed using univariate and multivariate Poisson regression models. RESULTS: The number of areas showing functional decline increased between admission and 1 month after discharge and had declined slightly at 3 months after discharge. The factors associated with the number of areas showing functional decline at 3 months after discharge were age, education level, and length of hospitalization (p < .05); the factors associated at 1 month after discharge were medical department and caregiver relationship (p < .05). CONCLUSION: The results indicate that older patients with no spouse or those with their elderly spouse as their caregiver are at risk of functional decline in a greater number of areas after discharge. Therefore, a comprehensive health-care policy to ensure care continuity is required for functional health maintenance for older adults after hospital discharge.

(1) Background: This study aimed to determine the relevance between stages of metabolic syndrome (MS) progression and the incidence of gastric cancer utilizing a big data cohort for the national health checkup. (2) Methods: There were 7,785,098 study subjects, and three stages of metabolic syndrome were categorized using the health checkup results from 2009. Incidence of gastric cancer was traced and observed from the date of the health insurance benefit claim in 2009 until 31 December, 2016, and Cox hazard-proportional regression was performed to determine the risk of gastric cancer incidence based on the stage of progression for metabolic syndrome. (3) Results: Hazard ratio (HR) incidence rate for the MS group was 2.31 times higher than the normal group (95% CI 2.22â»2.40) after adjustment (Model 4). The HR incidence rate of gastric cancer for the pre-MS group was 1.08 times higher (95% CI 1.04â»1.12) than the normal group, while the HR incidence rate of gastric cancer for the MS group was 1.26 times higher (95% CI 1.2â»1.32). (4) Conclusions: Causal relevance observed in this study between metabolic syndrome and incidence of gastric cancer was high. Promotion and education for active responses in the general population and establishment of appropriate metabolic syndrome management systems to prevent gastric cancer are needed.

PURPOSE: Dialysis-requiring acute kidney injury (AKI-D) after cardiac surgery is a major cause of in-hospital mortality. However, the long-term outcome has not been previously examined. MATERIALS AND METHODS: We performed a nationwide, population-based cohort study using the claims data in the Korean National Health Insurance System. Patients who underwent cardiac surgery between 2006 and 2015 were considered. RESULTS: Among 52,983 patients who underwent cardiac surgery, 1261 underwent dialysis postoperatively. During the median follow-up of 3.33â¯years, the AKI-D group had increased risk of all-cause mortality, end-stage renal disease (ESRD) progression, and risk of developing major adverse cardiovascular events (MACEs). These results remained consistent after multivariable analysis and propensity-score matching. Even after excluding patients who continued dialysis at discharge, the AKI-D group consistently exhibited worse mortality and an increased risk of MACEs compared to the control group. Patients who underwent continuous renal replacement therapy in the AKI-D group exhibited comparable mortality and risk of MACEs but reduced progression to ESRD compared to those who received intermittent renal replacement therapy. CONCLUSIONS: AKI-D following cardiac surgery was associated with worse long-term postdischarge mortality and elevated risks of dialysis dependency and MACE development. The outcomes were consistent even in the patients who recovered from the dialysis.
