Open AccessRisk of age older than 65 years for 30-day cardiac complication may be comparable to low-to-moderate risk according to revised cardiac risk index in non-cardiac surgery
Revised cardiac risk index (RCRI) is widely used for surgical patients without containing age as a risk factor. We investigated age older than 65 years with respect to low-to-moderate risk of RCRI. From Januar...

Open AccessSex differences in myocardial injury after non-cardiac surgery and postoperative mortality
Myocardial injury after non-cardiac surgery (MINS) has recently been accepted as a predictor of mortality. However, sex differences in the incidence of MINS and survival thereafter are not fully understood. Th...

Open AccessDays alive and out of hospital at 30 days and outcomes of off-pump coronary artery bypass grafting
Days alive and out of hospital (DAOH) is a simple estimator based on the number of days not in hospital within a defined period. In cases of mortality within the period, DAOH is regarded as zero. It has not be...

Open AccessPrediction model for myocardial injury after non-cardiac surgery using machine learning
Myocardial injury after non-cardiac surgery (MINS) is strongly associated with postoperative outcomes. We developed a prediction model for MINS and have provided it online. Between January 2010 and June 2019, ...

Open AccessAssociation between postoperative acute kidney injury and mortality after plastic and reconstructive surgery
Acute kidney injury (AKI) is a common postoperative disorder that is associated with considerable morbidity and mortality. Although the role of AKI as an independent risk factor for mortality has been well cha...

Open AccessVasoactive inotropic score as a predictor of long-term mortality in patients after off-pump coronary artery bypass grafting
Increased vasoactive-inotropic score (VIS) is a reliable predictor of mortality and morbidity after cardiac surgery. Here, we retrospectively evaluated the association between VIS and adverse outcomes in adult...

Open AccessThe use of renin angiotensin aldosterone system inhibitors may be associated with decreased mortality after cancer surgery
Renin–angiotensin–aldosterone system (RAAS) inhibitors are antihypertensive agents with conflicting results on protective effects against some types of cancer. In light of these controversies, we aimed to stud...

Open AccessAssociation between preoperative neutrophil–lymphocyte ratio and mortality after plastic and reconstructive surgery
Predictive factors associated with postoperative mortality have not been extensively studied in plastic and reconstructive surgery. Neutrophil–lymphocyte ratio (NLR), a systemic inflammation index, has been sh...

Open AccessThe Charlson Comorbidity Index is associated with risk of 30-day mortality in patients with myocardial injury after non-cardiac surgery
Myocardial injury after non-cardiac surgery (MINS) is a well-known and relevant indicator of early postoperative mortality, but factors related to increased mortality in MINS patients are as yet unknown. The C...

Open AccessAngiotensin converting enzyme inhibitors and incidence of lung cancer in a population based cohort of common data model in Korea
Contradictory findings exist about association of angiotensin-converting enzyme inhibitor (ACEi) and angiotensin receptor blocker (ARB) with lung cancer development. This was a retrospective observational coho...

Open AccessAssociation between neutrophil–lymphocyte ratio change during living donor liver transplantation and graft survival
Preoperative neutrophil–lymphocyte ratio (NLR), has shown a predictive value in living donor liver transplantation (LDLT). However, the change in the NLR during LDLT has not been fully investigated. We aimed t...
