BACKGROUND: Acute kidney injury is common in critically ill patients, many of whom receive renal-replacement therapy. However, the most effective timing for the initiation of such therapy remains uncertain. METHODS: We conducted a multinational, randomized, controlled trial involving critically ill patients with severe acute kidney injury. Patients were randomly assigned to receive an accelerated strategy of renal-replacement therapy (in which therapy was initiated within 12 hours after the patient had met eligibility criteria) or a standard strategy (in which renal-replacement therapy was discouraged unless conventional indications developed or acute kidney injury persisted for >72 hours)...

Acute right ventricular failure remains the leading cause of mortality associated with acute pulmonary embolism (PE). This article reviews the pathophysiology behind acute right ventricular failure and strategies for managing right ventricular failure in acute PE. Immediate clot reduction via systemic thrombolytics, catheter based procedures, or surgery is always advocated for unstable patients. While waiting to mobilize these resources, it often becomes necessary to support the RV with vasoactive medications...
