Randomized Controlled Trial
Evaluation of urea and creatinine change during continuous renal replacement therapy: effect of blood flow rate.
To determine if faster blood flow rate (BFR) has an effect on solute maintenance in continuous renal replacement therapy. ⋯ Faster BFR did not affect solute control in patients receiving CRRT; however, differences in urea and creatinine concentrations were influenced by serum haemoglobin and hours of treatment.

Observational Study
Predicting recovery from acute kidney injury in critically ill patients: development and validation of a prediction model.
Intensive care unit (ICU) patients with acute kidney injury (AKI) who recover kidney function within 28 days experience less severe chronic kidney impairment and have increased long term survival. The aims of this study were to develop and validate a risk prediction model to identify these patients. ⋯ We constructed and validated a simple model that can predict the chance of recovery from AKI in critically ill patients.

Observational Study
Smoking cessation therapy in Australian and New Zealand intensive care units: a multicentre point prevalence study.
To obtain an accurate estimate of smoking prevalence and smoking cessation support practices, including nicotine replacement therapy (NRT), in Australian and New Zealand intensive care units (ICUs). ⋯ The prevalence of smoking in Australian and New Zealand ICUs patients is high. Over half of participating ICUs reported the routine prescription of NRT despite uncertainty regarding the practice. Further research evaluating the safety and efficacy of NRT is required.

Albumin is used to resuscitate trauma patients but may increase intracranial pressure (ICP). Its effects on renal blood flow and function are unknown. Our aim was to examine the effects of hypertonic albumin on ICP and renal function, and if any effects are due to the hypotonicity of the solution containing albumin or to albumin itself. ⋯ Compared with saline or isotonic albumin solution, hypotonic albumin solution increased ICP and CVP, but did not alter arterial pressure, cardiac output renal blood flow or renal function. Our findings support the view that the tonicity of the albumin solution, rather than the albumin itself, is responsible for increasing ICP.
