The association of mean glucose level and glucose variability with intensive care unit mortality in patients with severe acute pancreatitis.
The objective of this study was to retrospectively analyze the association of mean glucose level (MGL) and glycemic lability index (GLI; as a measure of glucose variability) with intensive care unit (ICU) mortality in patients with severe acute pancreatitis (SAP). ⋯ We observed that GLI was a better predictor of ICU and hospital mortality than was MGL. Together with the second 24-hour APACHE II score and the number of organ failures upon ICU admission, GLI is an independent predictor of mortality in patients with SAP.

Stress hyperglycemia may not be harmful in critically ill patients with sepsis.
Stress hyperglycemia (SH) is commonly seen in critically ill patients. It has been shown to be associated with adverse outcomes in some groups of patients. The effects of SH on critically ill patients with sepsis have not been well studied. We aimed to evaluate the effects of SH in critically ill patients with sepsis. ⋯ Stress hyperglycemia may not be harmful in critically ill patients with sepsis. Patients with SH had lower ICU mortality.

Prevalence and significance of lactic acidosis in diabetic ketoacidosis.
The prevalence and clinical significance of lactic acidosis in diabetic ketoacidosis (DKA) are understudied. The objective of this study was to determine the prevalence of lactic acidosis in DKA and its association with intensive care unit (ICU) length of stay (LOS) and mortality. ⋯ Lactic acidosis is more common in DKA than traditionally appreciated and is not associated with increased ICU LOS or mortality. The positive correlation of lactate with glucose raises the possibility that lactic acidosis in DKA may be due not only to hypoperfusion but also to altered glucose metabolism.

Incidence and risk factors for sepsis in surgical patients: a cohort study.
The aim of the study was to evaluate risk factors for infection and sepsis in surgical patients admitted to the intensive care unit (ICU). ⋯ This study showed that sepsis has high incidence and mortality in surgical patients admitted to the ICU. Urgent surgeries, mechanical ventilation, fluid resuscitation, and vasoactive drugs in the postoperative period and Sequential Organ Failure Assessment at ICU admission were risk factors for sepsis.

Randomized Controlled TrialUse of simulation-based education to improve resident learning and patient care in the medical intensive care unit: a randomized trial.
The purpose of this study is to determine the effect of simulation-based education on the knowledge and skills of internal medicine residents in the medical intensive care unit (MICU). ⋯ Simulation-based education significantly improved resident knowledge and skill in the MICU. Knowledge acquired in the simulated environment was transferred to improved bedside skills caring for MICU patients. Simulation-based education is a valuable adjunct to standard clinical training for residents in the MICU.
