Acute kidney injury (AKI), at least in critically ill patients, seldom occurs as isolated organ failure. Much more often it emerges as a component of the multiple organ failure syndrome, within the framework of the severe and prolonged catabolic phase determined by critical illness, and intensified by specific derangements in substrate utilization due to the acute loss of kidney function. On these bases, patients with AKI often have protein-energy wasting (preexisting and/or hospital acquired), which represents a major negative prognostic factor. ⋯ The enteral route should be the preferred route for nutrient delivery; however, parenteral nutrition is often required to target nutritional requirements. Due to the loss of the kidney's homeostatic function, and the frequent need of RRT, patients with AKI are especially prone to complications of nutritional support, such as hyperglycemia, hypertriglyceridemia, fluid retention, electrolyte and acid-base derangements. Since AKI comprises a highly heterogeneous group of subjects with nutrient needs widely varying even along the clinical course in the same patient, nutritional requirements should be frequently reassessed, individualized and carefully integrated with RRT.

Case ReportsContinuous renal replacement therapy combined with extracorporeal membrane oxygenation in advanced cardiac failure patients.
Acute renal failure during extracorporeal membrane oxygenation (ECMO) support is associated with extremely high mortality. This report describes treatment of myocardial dysfunction in one 48-year-old and one 11-year-old patient. ⋯ Continuous venovenous hemodialysis was performed for acute renal failure with pulmonary edema and oliguria. Both patients survived following treatment with venoarterial ECMO combined with continuous venovenous hemodialysis.

The research to health policy cycle: a tool for better management of chronic noncommunicable diseases.
Effectively responding to the global epidemic of noncommunicable disease will require a new research paradigm that integrates decision-makers into every step of the work. We present a systematic, multidisciplinary, staged research framework that involves setting priorities, designing, pilot testing and implementing novel interventions, and translating the lessons learned for clinicians and other stakeholders. This framework could be used by health services researchers in other areas to increase the likelihood that their research will be incorporated into health policy. Used together with existing administrative data sets, this framework has the potential to create virtual "health policy laboratories" in which novel, cost-effective, equitable and efficacious approaches to improving health are identified and validated.
