The epidemiology of acute respiratory failure in hospitalized patients: a Brazilian prospective cohort study.
The purpose of this study was to assess risk factors associated with the development of acute respiratory failure (ARF) and death in a general intensive care unit (ICU). ⋯ Acute respiratory failure represents a large percentage of all ICU patients, and the high mortality is related to some preventable factors such as the time to ICU admission.

Multicenter StudyEarly changes of procalcitonin may advise about prognosis and appropriateness of antimicrobial therapy in sepsis.
The objective of this study is to define if early changes of procalcitonin (PCT) may inform about prognosis and appropriateness of administered therapy in sepsis. ⋯ Changes of serum PCT within the first 48 hours reflect the benefit or not of the administered antimicrobial therapy. Serial PCT measurements should be used in clinical practice to guide administration of appropriate antimicrobials.

Randomized Controlled TrialMild hypothermia therapy reduces blood glucose and lactate and improves neurologic outcomes in patients with severe traumatic brain injury.
The study aimed to investigate the association between blood glucose or lactate and the outcomes of severe traumatic brain injury (TBI), and to evaluate the effect of mild hypothermia therapy on glucose and lactate levels. ⋯ Hyperglycemia after TBI was associated with poor clinical outcomes, but the predictive value of blood lactate level requires further investigation. Hypothermia therapy improves neurologic outcomes in patients with severe TBI, and reduction in blood glucose may be partially responsible for the improved outcomes.

Intensive care unit admissions for community-acquired pneumonia are seasonal but are not associated with weather or reports of influenza-like illness in the community.
The aims of this study were to determine if there is seasonal variation in the number of intensive care unit (ICU) admissions for community-acquired pneumonia (CAP) and if there is a relationship between these admissions and weather or reports of influenza-like illness in the community. ⋯ Intensive care unit admissions for CAP are seasonal, but neither weather measurements nor weekly rate of reported influenza-like illness in the community is associated with these admissions.

Costs and cost-effectiveness of a telemedicine intensive care unit program in 6 intensive care units in a large health care system.
The purpose of this study is to estimate the costs and cost-effectiveness of a telemedicine intensive care unit (ICU) (tele-ICU) program. ⋯ Hospital administrators may conclude that a tele-ICU program aimed at the sickest patients is cost-effective.
