EVERE SEPSIS REMAINS AN IMPORtant cause of death, accounting for 9.3% of all deaths in the United States in 1995. 1 If our understanding of the mechanisms of host response to stress has strongly progressed during the last 2 decades, 2 the various drugs developed for specific targets of the cytokine cascade have failed to improve patient survival. 3,4 Corticosteroids were the first antiinflammatory drugs tested in randomized trials. At high doses during short courses, they did not induce favorable effects. 5,6 However, the observation that severe sepsis may be associated with relative adrenal insufficiency 7,8 or systemic inflammation-induced glucocorticoid receptor resistance 9 prompted renewed interest of a replacement therapy

Limited training of noncardiologist ICU residents without previous knowledge in ultrasound appears feasible and efficient to address simple clinical questions using point-of-care echography. Influence of the learning curve on diagnostic accuracy and potential therapeutic impact remain to be determined.

Our findings suggest that ventilator-associated pneumonia remains a common ICU infection and that P. aeruginosa is one of the most common causative pathogens. The odds of developing P. aeruginosa ventilator-associated pneumonia were eight times higher in patients with prior P. aeruginosa colonization than in uncolonized patients, which in turn was associated with local resistance.

Bedside ultrasonography is well suited for the quantitative assessment of unloculated pleural effusions in intensive care unit patients.

BackgroundAcute kidney injury (AKI) is a common complication of critical illness and is associated with worse outcomes. However, the influence of deterioration or improvement in renal function on clinical outcomes is unclear. Using a large international database, we evaluated the prevalence and evolution of AKI over a 7-day period and its effects on clinical outcomes in septic and non-septic critically ill patients worldwide.MethodsFrom the 10,069 adult intensive care unit (ICU) patients in the Intensive Care Over Nations database, all those with creatinine and urine output data were included in this substudy. Patients who developed sepsis during the ICU stay (≥ 2 days after admission) were excluded. AKI was evaluated within 72 hours after admission and before discharge/death up to day 7 according to the Acute Kidney Injury Network (AKIN) criteria.ResultsA total of 7970 patients were included, 59% of whom met AKIN criteria for AKI within the first 72 hours of the ICU stay. Twenty-four per cent of patients had sepsis on admission, of whom 68% had AKI, compared to 57% of those without sepsis on admission (p < 0.001). AKIN stage 3 (40% vs 24%, p < 0.001) and use of renal replacement therapy (20% vs 5%, p < 0.0001) were more prevalent in patients with sepsis. Patients with sepsis and AKIN stage 3 were less likely to improve to a lower stage during the 7-day follow-up period than non-septic patients with AKIN stage 3 (21% vs 32%, p < 0.0001). In-hospital mortality was related to severity of AKI and was reduced in patients in whom AKI improved compared to those who remained stable or deteriorated, but remained higher than in patients without AKI, even if there was apparent full recovery at day 7.ConclusionThese findings illustrate the different kinetics of AKI in septic and non-septic ICU patients and emphasize the important impact of AKI on mortality rates even when there is apparent full renal recovery at day 7.Electronic supplementary materialThe online version of this article (10.1186/s13054-018-2112-z) contains supplementary material, which is available to authorized users.
