RESUMO
As the home-meal replacement food industry grows, there is an increasing need for smoky flavorings that can satisfy the diverse tastes of consumers. In particular, the industry requires chargrilled flavorings that complement Korean foods. In this study, chargrilled flavoring was applied to bulgogi (Korean barbecued beef) and its effects on consumer liking, sensory perception, familiarity, and flavor congruency with the bulgogi were investigated. Eight formulations (one control and seven flavorings) were tested by 78 Korean subjects. A rate-all-that-apply test was conducted to profile the sensory attributes of the food from the consumers' perspectives. The samples with weaker woody and smoky flavors were preferred; the samples with strong woody and smoky flavors were perceived as being artificial and Western-styled, as well as less familiar and incongruent with bulgogi. This study shows that flavorings that are congruent with a food system can improve consumer liking and the perception of familiarity.
RESUMO
BACKGROUND: This study aimed to evaluate the association between intraoperative blood loss and myocardial injury after non-cardiac surgery (MINS), which is a severe and common postoperative complication. METHODS: We compared the incidence of MINS based on significant intraoperative bleeding, defined as an absolute hemoglobin level < 7 g/dL, a relative hemoglobin level less than 50% of the preoperative measurement, or need for packed red cell transfusion. We also estimated a threshold for intraoperative hemoglobin level associated with MINS. RESULTS: We stratified a total of 15,926 non-cardiac surgical patients with intraoperative hemoglobin and postoperative cardiac troponin (cTn) measurements according to the occurrence of significant intraoperative bleeding; 13,416 (84.2%) had no significant bleeding while 2,510 (15.8%) did have significant bleeding. After an adjustment with inverse probability weighting, the incidence of MINS was higher in the significant bleeding group (35.2% vs. 16.4%; odds ratio, 1.58; 95% confidence interval, 1.43-1.75; p < 0.001). The threshold of intraoperative hemoglobin associated with MINS was estimated to be 9.9 g/dL with an area under the curve of 0.643. CONCLUSION: Intraoperative blood loss appeared to be associated with MINS. Further studies are needed to confirm these findings. CLINICAL REGISTRATION: The cohort was registered before patient enrollment at https://cris.nih.go.kr (KCT0004244).

BACKGROUND: Pre-operative anaemia is associated with adverse outcomes of noncardiac surgery, but its association with myocardial injury after noncardiac surgery (MINS) has not been fully investigated. OBJECTIVE: The association between pre-operative anaemia and MINS. DESIGN: A single-centre retrospective cohort study. SETTING: Tertiary care referral centre. PATIENTS: Patients with measured cardiac troponin (cTn) I levels after noncardiac surgery. INTERVENTIONS: Patients were separated according to pre-operative anaemia (haemoglobin <13âgâdl-1 in men and <12âgâdl-1 in women). Anaemia was further stratified into mild and moderate-to-severe at a haemoglobin level threshold of 11âgâdl-1. MAIN OUTCOME MEASURES: The primary outcome was MINS, defined as a peak cTn I level more than 99th percentile of the upper reference limit within 30 postoperative days. RESULTS: Data from a total of 35 170 patients were collected, including 22â062 (62.7%) patients in the normal group and 13â108 (37.3%) in the anaemia group. After propensity score matching, 11919 sets of patients were generated, and the incidence of MINS was significantly associated with anaemia [14.5 vs. 21.0%, odds ratio (OR) 1.57, 95% confidence interval (CI) 1.47 to 1.68, Pâ<â0.001]. For the entire population, multivariable analysis showed a graded association between anaemia severity and MINS (OR 1.32, 95% CI 1.22 to 1.43, Pâ<â0.001 for mild anaemia and OR 1.80, 95% CI 1.66 to 1.94, Pâ<â0.001 for moderate-to-severe anaemia compared with the normal group) and a significantly higher incidence of MINS for moderate-to-severe anaemia than mild anaemia (18.6 vs. 28.6%, OR 1.37, 95% CI 1.25 to 1.50, Pâ<â0.001). The estimated threshold for pre-operative haemoglobin associated with MINS was 12.2âgâdl-1, with an area under the curve of 0.622. CONCLUSIONS: Pre-operative anaemia was independently associated with MINS, suggesting that MINS may be related to the association between anaemia and postoperative mortality.

Myocardial injury after noncardiac surgery (MINS) is recently accepted as a strong predictor of mortality, regardless of symptoms. However, anticoagulation is the only established treatment. This study aimed to evaluate the association between statin treatment and mortality after MINS. From January 2010 to June 2019, a total of 5,267 adult patients who were discharged after the occurrence of MINS were enrolled. The patients were divided into two groups according to statin prescription at discharge. The outcomes were 1-year and overall mortalities. Of the total 5,109 patients, 1,331 (26.1%) patients were in the statin group and 3,778 (73.9%) patients were in the no statin group. The 1-year and overall mortalities were significantly lower in the statin group compared with the no statin group (6.1% vs. 13.3%; hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.41-0.74; p < 0.001 for 1-year mortality and 15.0% vs. 25.0%; HR, 0.62; 95% CI, 0.51-0.76; p < 0.001 for overall mortality). Analyses after inverse probability treatment weighting showed similar results (HR, 0.61; 95% CI, 0.50-0.74; p < 0.001 for 1-year mortality and HR, 0.70; 95% CI, 0.54-0.90; p = 0.006 for overall mortality), and the mortalities did not differ according to the dose of statin. Our results suggest that statin treatment may be associated with improved survival after MINS. A trial is needed to confirm this finding and establish causality.
