Analysis of intake trends of kimchi, fruits and vegetables (1998–2020) and factors associated with the intake (2016–2020): based on the Korea National Health and Nutrition Examination Survey / 한국영양학회지

Purpose@#This study aimed to analyze the trends in kimchi, vegetable, and fruit consumption among the Korean population and identify the factors associated with this consumption.The goal was to provide fundamental data for developing appropriate guidelines to increase kimchi consumption by understanding its characteristics. @*Methods@#The analysis utilized data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 1998 and 2020. A total of 81,680 adults, aged 30 years or older, were included in the trend analysis. For the analysis of factors associated with kimchi, vegetable, and fruit intake, a subgroup of 22,122 adults aged 30 years or older from the KNHANES (2016-2020) was divided into two groups: 30–64 years old and 65 years old or older. Since the KNHANES data employed a complex sampling design, the statistical analysis was conducted using the appropriate complex sampling design method. @*Results@#The overall consumption of kimchi exhibited a declining trend among both men and women. Specifically, there was a significant decline in the intake of baechu kimchi among both genders. The decline in kimchi consumption above the standard was associated with a decrease in meal frequency and an increase in the frequency of eating alone. However, the patterns for unsalted vegetables and fruits differed compared to kimchi. @*Conclusion@#In this study, there was a decline in kimchi consumption among both men and women, and the potential factors associated with this trend included Westernized dietary habits, the presence of a spouse who influenced dietary habits, and an increased frequency of solitary dining due to the rise in single-person households. Therefore, it is necessary to develop dietary guidelines that consider these factors.

The prognostic usefulness of the lactate/albumin ratio for predicting multiple organ dysfunction syndrome in severe trauma

Objective@#Early prediction of the multiple organ dysfunction syndrome (MODS) and providing early innovative treatment may improve outcomes in patients with severe trauma. Lactate and serum albumin levels, which are widely used markers predicting the severity of critically ill patients, tend to diverge during clinical deterioration. This study aimed to evaluate the clinical utility of the lactate/albumin ratio (LAR) as a predictive factor for MODS and 30-day mortality in patients with severe trauma. @*Methods@#This retrospective, observational cohort study was performed with patients prospectively integrated into a critical pathway for trauma. We analyzed severe trauma patients (Injury Severity Score≥16) admitted to the emergency department (ED), between January 1, 2011, and May 31, 2017. The outcomes were the development of MODS and 30-day mortality. @*Results@#In total, 348 patients were enrolled, of which 18 (5.2%) died within 96 hours of ED admission, and the remaining 330 patients (94.8%) were evaluated for the development of MODS. An increase in the LAR at admission (odds ratio, 1.618; P=0.028) was an independent predictor of MODS development. The area under the receiver operating characteristic curve (0.755) and Harrell's C-index (0.783) showed that LAR could predict MODS and 30-day mortality. @*Conclusion@#Initial LAR is an independent predictor of MODS development in patients with severe trauma. Our study results suggest that an elevated LAR can be a useful prognostic marker in patients with severe trauma.

Effect of ulinastatin on perioperative organ function and systemic inflammatory reaction during cardiac surgery: a randomized double-blinded study / 대한마취과학회지

BACKGROUND: This study evaluated the efficacy of ulinastatin for attenuating organ injury and the release of proinflammatory cytokines due to cardiopulmonary bypass (CPB) during cardiac surgery. METHODS: Patients undergoing valvular heart surgery employing CPB were assigned to receive either ulinastatin (group U, n = 13) or a placebo (group C, n = 11) before the commencement of CPB. Hemodynamic data, parameters of major organ injury and function, and proinflammatory cytokines were measured after the induction of anesthesia (T1), after CPB (T2), at the end of anesthesia (T3), and at 24 hours after surgery (POD). RESULTS: The demographic data, CPB duration, and perioperative transfusions were not different between the groups. PaO2/FiO2 in group U was significantly higher than that in group C at T3 (3.8 +/- 0.8 vs. 2.8 +/- 0.7, P = 0.005) and at POD (4.0 +/- 0.7 vs. 2.8 +/- 0.7, P < 0.001). Creatine kinase-MB at POD in group U was significantly lower than that in group C (17.7 +/- 8.3 vs. 33.7 +/- 22.1, P = 0.03), whereas troponin I at POD was not different between the groups. Creatinine clearance and the extubation time were not different between the groups at POD. The dopamine infusion rate during the post-CPB period in group U was significantly lower than that in group C (1.6 +/- 1.6 vs. 5.5 +/- 3.3 microg/kg/min, P = 0.003). The interleukin-6 and tumor necrosis factor-alpha concentrations at T1, T2, and T3 as well as the incidences of postoperative cardiac, pulmonary and kidney injuries were not different between the groups. CONCLUSIONS: Ulinastatin pretreatment resulted in an improved oxygenation profile and reduced inotropic support, probably by attenuating the degree of cardiopulmonary injury; however, it did not reduce the levels of proinflammatory cytokines.
