ReviewFluid removal in acute heart failure: diuretics versus devices.
Fluid removal and relief of congestion are central to treatment of acute heart failure. Diuretics have been the decongestive mainstay but their known limitations have led to the exploration of alternative strategies. This review compares diuretics with ultrafiltration and examines the recent evidence evaluating their use. ⋯ Decongestion remains a major challenge in acute heart failure. Although recent studies provide useful data to guide practice, the relatively poor outcomes point to the continued need to identify better strategies for safe and effective decongestion.

Because of heart-lung interactions, weaning from mechanical ventilation induces strong hemodynamic changes that can lead to weaning-induced cardiac failure. Cardiac patients are particularly at risk for this complication. In this review, we will summarize the most recent advances concerning the mechanisms, diagnosis and treatment of weaning-induced cardiac failure. ⋯ Nowadays, the diagnosis of weaning-induced pulmonary edema can be easily made. Identifying such an event is important as an appropriate treatment, guided by the suspected mechanisms leading to the cardiac failure, should hasten weaning from mechanical ventilation.

We aim to help clinicians to use and interpret high-sensitivity cardiac troponins (cTns) in different acute care settings. This guidance is timely and relevant as high-sensitivity cTns are currently replacing conventional cTn assays in most parts of the world. ⋯ In all of these, elevated levels of high-sensitivity cTn are associated with increased mortality risk. In some of these, concepts are evolving as to how the pathophysiological signal of cardiomyocyte injury could be used to alter patient management and potentially improve outcomes.

ReviewAntibiotic treatment of ventilator-associated tracheobronchitis: to treat or not to treat?
To evaluate the data on antimicrobial therapy for ventilator-associated tracheobronchitis (VAT) to prevent ventilator-associated pneumonia (VAP), and its impact on patient outcomes. ⋯ This review focuses on diagnostic criteria for VAT and VAP, etiologic agents, rationale and benefits of initiating pre-emptive, appropriate antibiotic treatment for VAT to prevent VAP, improve patient outcomes and associated acute and chronic healthcare costs.
