Antibiotic allergy de-labeling in the intensive care unit: The prospective ADE-ICU study.
Critically ill patients in the intensive care unit (ICU) are frequently prescribed antibiotics, with many reporting an antibiotic allergy label, predominantly to penicillin. Mislabeling contributes to suboptimal antibiotic use, increasing multidrug-resistant organisms and Clostridium difficile infections, and increased hospital length of stay. This prospective study implemented an antibiotic allergy assessment and testing program in the ICU, independently of clinical immunology/allergy services. ⋯ This study shows the feasibility of ICU led antibiotic allergy assessment and testing, highlighting a potential model for implementation in settings lacking immunology/allergy services.

Postoperative oliguria after intermediate and high-risk surgeries in critical care, A cohort analysis.
Oliguria is commonly used as a cutoff for acute kidney injury (AKI), however, a decrease in urine output is common during surgery and may represent an adaptative response in the perioperative setting rather than a reduction in glomerular filtration rate, leading to a possible overestimation of postoperative AKI incidence. Although this dilemma has been addressed in the intraoperative scenario, the incidence and impact of oliguria in the first postoperative day represents a gap in the current literature. Our main goal is to describe the incidence, risk factors and clinical outcomes related to postoperative oliguria. ⋯ Postoperative oliguria is common after intermediate and high-risk surgical procedures and increases the risk of AKI. However, oliguria was largely unrelated with kidney disfunction measured by serum creatinine (87,6 %), raising doubts on whether diuresis overestimates AKI incidence in the postoperative setting.

ReviewUnderstanding ventilator-induced lung injury: The role of mechanical power.
Mechanical ventilation stands as a life-saving intervention in the management of respiratory failure. However, it carries the risk of ventilator-induced lung injury. Despite the adoption of lung-protective ventilation strategies, including lower tidal volumes and pressure limitations, mortality rates remain high, leaving room for innovative approaches. ⋯ To overcome the constraints of measuring static respiratory parameters, dynamic mechanical power is proposed for all patients, regardless of their ventilation mode. However, establishing a causal relationship is crucial for its potential implementation, and requires further research. The objective of this review is to explore the role of mechanical power in ventilator-induced lung injury, its association with patient outcomes, and the challenges and potential benefits of implementing a ventilation strategy based on mechanical power.

The furosemide stress test predicts successful discontinuation of continuous renal replacement therapy in critically ill patients with acute kidney injury.
There is still no good method for predicting renal recovery and successful discontinuation of continuous renal replacement therapy (CRRT). This study assessed the ability of the furosemide stress test (FST) to predict successful discontinuation of CRRT. ⋯ A urine output >188 mL in the first 2 h after FST predicted successful discontinuation of CRRT.

Meta AnalysisProtective effect of intravenous amino acid on kidney function: A systematic review and meta-analysis of randomized controlled trials.
Acute kidney injury (AKI) is a common complication in critically ill and cardiac surgery patients. Intravenous amino acids can increase renal perfusion and replenish renal functional reserves. However, the exact therapeutic efficacy of intravenous amino acids in reducing the incidence of AKI remains uncertain. Therefore, this study aims to comprehensively review the existing evidence to assess the potential of intravenous amino acids in kidney protection. ⋯ Intravenous amino acids protect renal function in patients at high risk of AKI, particularly after cardiac surgery. It reduces the incidence of AKI and increases urine output, but has no significant effect on KRT and mortality.
