Cardiac troponins in serum have become the biomarkers of choice for the diagnosis of myocardial infarction. Yet, troponin can also be elevated by a multitude of causes in the absence of overt myocardial ischemia. Such nonspecific elevations are particularly common in the critically ill. This article aims to provide information on the significance of troponin elevations in unselected critically ill patients and in patients with sepsis or septic shock. ⋯ Troponin is frequently elevated in critically ill patients. More research is needed on the diagnostic and prognostic significance and possible clinical applications of troponin measurements in patients with sepsis and critical illness.

Unilateral pulmonary edema (UPE) is an unusual manifestation of pulmonary edema that is frequently confused with other causes of unilateral alveolar and interstitial infiltrates. Until now limited data existed regarding the prevalence, cause, and outcome of patients presenting with cardiogenic UPE. The purpose of this review is to give insights into this rare entity. ⋯ UPE is not that rare as considered to be and is mostly related to severe organic or functional mitral regurgitation. Probably because of initial misdiagnosis and delayed appropriate treatment, UPE is related to increased mortality. History, absence of signs of infection, and elevated serum cardiac markers such as B-natriuretic peptide may help to differentiate UPE from other diagnoses. The key examination remains bedside transthoracic echocardiography, although transesophageal echocardiography can also provide additional information regarding the severity and mechanism of mitral regurgitation and documentation of the differential pressure between the right and left pulmonary veins.

The scope of this review is to describe what is known about injury outcomes and the principles by which they can be improved by acute phase interventions. Assessing which outcomes matter to trauma patients is important both for the evaluation of existing and novel acute interventions and to assess the delivery of care within trauma systems' performance improvement frameworks. ⋯ Improving outcomes in the acute phase of trauma care requires the timely delivery of complex interventions with an organized trauma system. Research is needed both in developing novel interventions and in developing and validating patient-centred and surrogate outcome tools.

To discuss recent data relating to survival rates after cardiac arrest and interventions that can be used to optimize outcome. ⋯ In several centres, survival rates following OHCA are increasing. All links in the chain of survival must be optimized if a good-quality neurological outcome is to be achieved.

The incidence of cirrhosis is growing steadily and this cohort of patients will present in ever-greater numbers to critical care with acute decompensation, usually secondary to an inter-current event or following elective surgery. This review examines the evidence for treatment options and outcomes. ⋯ Critical care support should be offered to patients with cirrhosis and in high-risk variceal bleed patients transhepatic portosystemic shunt should be considered.
