<h3>Importance</h3> Histamine-2 receptor antagonists (H<sub>2</sub>RAs) and proton pump inhibitors (PPIs) are commonly used to prevent gastrointestinal tract (GI) hemorrhage in critically ill patients. The stronger acid suppression of PPIs may reduce the rate bleeding but enhance infectious complications, specifically pneumonia and<i>Clostridium difficile</i>infection (CDI). <h3>Objective</h3> To evaluate occurrence risk factors for GI hemorrhage, pneumonia, CDI <h3>Design, Setting,...

Extracorporeal treatments (ECTRs), such as hemodialysis and hemoperfusion, are used in poisoning despite a lack of controlled human trials demonstrating efficacy. To provide uniform recommendations, the EXTRIP group was formed an international collaboration among recognized experts from nephrology, clinical toxicology, critical care, or pharmacology supported by over 30 professional societies. For every poison, benefit ECTR is weighed against associated complications, alternative therapies,...

Abstract Introduction Intravenous (IV) voriconazole is not recommended in patients with creatinine clearance &lt;50 ml/min to avoid potentially toxic accumulation of sulfobutylether-β-cyclodextrin (SBECD). The purpose this study was evaluate the pharmacokinetics SBECD, voriconazole, and N-oxide critically ill undergoing continuous renal replacement therapy (CRRT) determine if CRRT removes SBECD sufficiently allow for use IV without significant risk accumulation. Methods This prospective,...
