Multicenter Study Observational StudyApplication of dynamic pulse pressure and vasopressor tools for predicting outcomes in patients with sepsis in intensive care units.
We aimed to determine whether the combination of dynamic pulse pressure and vasopressor (DPV) use is applicable for mortality risk stratification in patients with severe sepsis. We proposed the use of the DPV tool and compared it with traditional sepsis severity indices. ⋯ The DPV tool can be applied for 7-day and 28-day mortality risk prediction in patients with sepsis.

Comparative Study Observational StudyEarly target attainment of continuous infusion piperacillin/tazobactam and meropenem in critically ill patients: A prospective observational study.
To evaluate target attainment of empirically dosed continuous infusion piperacillin/tazobactam (TZP) and meropenem (MER) in critically ill patients. ⋯ Target attainment of empiric antibiotic therapy in critically ill patients was low (37%) for TZP and moderate (75%) for MER, despite the use of a loading dose and despite optimization of the mode of infusion.

Observational StudyInfluence of systemic hemodynamics on microcirculation during sepsis.
During sepsis, improvement of hemodynamic may not be related to improvement of microcirculation. The aim of this study was to investigate influence of systemic circulation on microcirculation in septic ICU patients. ⋯ DAP was the only independent determinant of resStO2 in septic patients. Fluid challenges may improve microcirculation. CVP did not influence resStO2.

Epidemiological risk factors for nosocomial bloodstream infections: A four-year retrospective study in China.
The objective of this study was to retrospectively research the clinical characteristics, pathogen distribution, prognosis of nosocomial bloodstream infection (nBSI), and the associated risk factors for nBSI. ⋯ Gram-negative bacteria predominantly developed in nBSI. Timely removal of venous catheters (catheter retention time ≥ 7 days) and implementation of appropriate empirical therapy improved the nBSI outcomes.

Goal of this study was to describe incidence and outcome of gastrointestinal failure (GIF) in ICU patients, evaluate its additive role to SOFA score in mortality prediction and describe GIF according to etiology. ⋯ Gastrointestinal failure, independent of origin, is associated with worse ICU outcome. Similar to other organ failures included in SOFA score, GIF independently predicts mortality.
