Renal dysfunction is a risk marker in patients who candidate for coronary artery bypass graft (CABG). Renal disorder is associated with prolonged stays in intensive care unit and hospital, morbidity and mortality. Aim of this study is specific evaluation of association between preoperative creatinine (Cr) with atrial fibrillation (AF) after elective off-pump CABG in non-diabetic male patients w...

Ring fencing (RF) is defined as separating elective from emergency operations in parallel hospital production lines. This study examines the effects of RF of elective surgery on hospital efficiency. The analysis is performed on two levels. First, an intensive three-month study at the departmental level of three hospitals was performed. Second, a panel data analysis of the organizational populat...

OBJECTIVES To develop a multivariate predictive risk score of perioperative in-hospital stroke after coronary artery bypass grafting (CABG) surgery. METHOD A total of 26 347 patients were enrolled from 21 Spanish hospital databases. Logistic regression analysis was used to predict the risk of perioperative stroke (ictus or transient ischaemic attack). The predictive scale was developed from a...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...
