Effects of low versus high inspired oxygen fraction on myocardial injury after transcatheter aortic valve implantation: A randomized clinical trial.

Background: Oxygen therapy is used in various clinical situation, but its clinical outcomes are inconsistent. The relationship between the fraction of inspired oxygen (FIO2) during transcatheter aortic valve implantation (TAVI) and clinical outcomes has not been well studied. We investigated the association of FIO2 (low vs.

Bibliometric analysis of research articles on post-herpetic neuralgia published from 1991 to 2020.

Post-herpetic neuralgia (PHN) is one of the most painful diseases, which has made it a major concern for pain physicians. We aimed to quantitatively analyze the research outputs of studies on PHN published over the past 30 years using bibliometric analysis. We also aimed to analyze the research outputs of studies on interventional treatments for PHN and evaluate the academic achievements of Korean pain physicians.

Ultrasound-assisted spinal anesthesia: A randomized comparison between midline and paramedian approaches.

Study Objective: Neuraxial ultrasonography can improve the technical performance of spinal anesthesia. However, there are no data regarding the optimal approach for ultrasound-assisted spinal anesthesia. This study aimed to compare the midline and paramedian approaches for ultrasound-assisted spinal anesthesia in adult orthopedic patients.

Performance of the ACEF and ACEF II risk scores in predicting mortality after off-pump coronary artery bypass grafting.

Study Objective: The age, creatinine, and ejection fraction (ACEF) I and II scores are known to predict operative mortality after cardiac surgery. However, data from few cases of off-pump coronary artery bypass grafting (OPCAB) were considered during the development of these scores. This study aimed to validate and update the ACEF I and II scores for the prediction of in-hospital mortality after OPCAB.

Cephalocaudal tumor diameter is a predictor of diabetes insipidus after endoscopic transsphenoidal surgery for non-functioning pituitary adenoma.

Purpose: Diabetes insipidus (DI) develops commonly after endoscopic transsphenoidal surgery (ETS). We retrospectively investigated the incidence, onset, duration and predictors of DI after ETS in patients with non-functioning pituitary adenoma (NFPA).

Methods: A total of 168 patients who underwent ETS to remove NFPAs were included.

Safety and efficacy of immune checkpoint inhibitors for end-stage renal disease patients undergoing dialysis: a retrospective case series and literature review.

Despite the lack of safety and efficacy data regarding immune checkpoint inhibitors (ICIs) for renal dysfunction, they have been approved to treat even in the patients with end-stage renal disease (ESRD). We report our experience with ICI administration to three ESRD patients undergoing hemodialysis. One of the patients had a partial response for several months; however, the other patients had a stable disease while undergoing dialysis.
