rmediate-risk pulmonary embolism, fluid loading increased right ventricular preload and right ventricular stroke volume, whereas diuretics decreased right ventricular preload and right ventricular stroke volume without affecting mean arterial pressure.

In a porcine model of acute intermediate-risk pulmonary embolism, fluid loading increased right ventricular preload and right ventricular stroke volume, whereas diuretics decreased right ventricular preload and right ventricular stroke volume without affecting mean arterial pressure.

Acute kidney injury is frequent in polytrauma patients, and it is associated with increased mortality and extended hospital length of stay. However, the specific prevalence of acute kidney injury after traumatic brain injury is less recognized. The present study aims to describe the occurrence rate, risk factors, timing, and association with outcome of acute kidney injury in a large cohort of traumatic brain injury patients.

The Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury is a multicenter, prospective observational, longitudinal, cohort study.

Sixty-five ICUs across Europe.

For the present study, we selected 4,509 traumatic brain injury patients with an ICU length of stay greater than 72 hours and with at least two serum creatinine values during the first 7 days of ICU stay.

We classified acute kidney injury in three stages according to the Kidney Disease Improving Global Outcome criteria acute kidney injury stage 1 equals to serum creatinine × 1.5-1.9 times f= 2.52; 95% CI, 1.22-5.197; p = 0.012), hypernatremia (hazard ratio = 1.88; 95% CI, 1.31-2.71; p = 0.001), and osmotic therapy administration (hazard ratio = 2.08; 95% CI, 1.45-2.99; p < 0.001) were significantly associated with the risk of developing acute kidney injury. Acute kidney injury was also associated with an increased ICU length of stay and with a higher probability of 6 months unfavorable Extended Glasgow Outcome Scale and mortality.

Acute kidney injury after traumatic brain injury is an early phenomenon, affecting about one in 10 patients. Its occurrence negatively impacts mortality and neurologic outcome at 6 months. Osmotic therapy use during ICU stay could be a modifiable risk factor.

Because significantly higher mortality is observed in elderly patients undergoing venoarterial extracorporeal membrane oxygenation for refractory cardiogenic shock, decision-making in this setting is challenging. We aimed to elucidate predictors of unfavorable outcomes in these elderly (≥ 70 yr) patients.

Analysis of international worldwide extracorporeal life support organization registry.

Refractory cardiogenic shock due to various etiologies (cardiac arrest excluded).

Elderly patients (≥ 70 yr).

Venoarterial extracorporeal membrane oxygenation.

Three age groups (70-74, 75-79, ≥80 yr) were in-depth analyzed. Uni- and multivariable analysis were performed. From January 1997 to December 2018, 2,644 patients greater than or equal to 70 years (1,395 [52.8%] 70-74 yr old, 858 [32.5%] 75-79 yr, and 391 [14.8%] ≥ 80 yr old) were submitted to venoarterial extracorporeal membrane oxygenation for refractory cardiogenic shock with marked increase in the most recent years. Peripheral access was applied in mality followed in extracorporeal membrane oxygenation for sepsis.

This study confirmed the remarkable increase of venoarterial extracorporeal membrane oxygenation use in elderly affected by refractory cardiogenic shock. Despite in-hospital mortality remains high, venoarterial extracorporeal membrane oxygenation should still be considered in such setting even in elderly patients, since increasing age itself was not linked to increased mortality, whereas several predictors may guide indication and management.

To evaluate long-term uptake of an antimicrobial stewardship audit-and-feedback program along with potential predictors of stewardship suggestions and acceptance across a diverse ICU population.

A retrospective cohort study.

An urban, academic medical institution.

Patients admitted to an ICU who received an antimicrobial stewardship program suggestion between June 2010 and September 2019.

None.

The antimicrobial stewardship program provided 7,749 antibiotic assessments over the study period and made a suggestion to alter therapy in 2,826 (36%). Factors associated with a higher likelihood of receiving a suggestion to alter therapy included shorter hospital length of stay prior to antimicrobial stewardship program review (odds ratio 1.15 for ≤ 5 d; 95% CI 1.00-1.32), admission to cardiovascular (1.37; 1.06-1.76) or burn surgery (1.88; 1.50-2.36) versus general medicine, and preceding duration of antibiotic use greater than 5 days (1.33; 1.10-1.60). Assessment of aminoglycosides (2.91; 1.85-4.89), caggestions to alter potentially nephrotoxic agents, increased efforts toward specialized care units, and further work approaching infectious sources that are typically treated without pathogen confirmation and identification.

An antimicrobial stewardship program implemented over a decade resulted in sustained suggestion and acceptance rates.
