The objective of this study was to determine the effect of early vs late vasopressin therapy on catecholamine dose and duration. ⋯ Early initiation of vasopressin therapy in adult critically ill patients with septic shock was associated with no difference in total catecholamine requirements but decreased incidence of new onset arrhythmias.

EditorialBiophilosophical basis for identifying the death of a person.
The capacity for consciousness and self-awareness is uniquely synonymous with human life and personhood, and its absence is necessary and sufficient to identify that death has occurred. The presence of these functions is uniquely synonymous with human life. Ongoing organ function, response to infection, growth, wound healing, or the ability to sustain an unborn fetus do not alone constitute the unique experience of life and personhood. ⋯ Progressive hypoxia that is seen in many patients after withdrawal of advanced physiologic support leads to apnea and then circulatory arrest. The outward sign of apnea that is then followed by circulatory arrest is the basis for inferring that irreversible loss of capacity for consciousness and self-awareness has occurred and that death can be identified has having occurred. The capacity for consciousness and self-awareness is the only irreplaceable emergent phenomenon—arising from physiologic function of the brain—that is necessary and sufficient to define the life of a person.

Procalcitonin, as an early biomarker of colorectal anastomotic leak, facilitates enhanced recovery after surgery.
Procalcitonin (PCT) is a biomarker used to help sepsis diagnosing and monitoring and guide antibiotic therapy. Anastomotic leak (AL) after colorectal surgery is a severe complication associated with relevant short- and long-term sequelae. The aim of our study is to assess the predictive value of PCT levels to early diagnose AL after colorectal surgery. ⋯ Compared with more established biochemical values such as CRP and WBC, PCT is an earlier, more sensitive, and reliable marker of AL. Increased PCT levels in early PODs after colorectal surgery may provide a more effective way to detect AL, before clinical symptoms appear. Moreover, normal PCT values might be also a useful marker to facilitate a safe and early discharge of selected patients after colorectal surgery.

Renal outcome after vancomycin treatment and renal replacement therapy in patients with severe sepsis and septic shock: A retrospective study.
Acute kidney injury during systemic infections is common; however, renal outcome is poorly investigated. The increase of multiresistant pathogens leads to the use of potential nephrotoxic antibiotics as vancomycin. We investigated the impact of vancomycin and renal replacement therapy (RRT) for renal recovery during sepsis. ⋯ Estimated GFR at ICU admission predicts renal outcome, whereas the use of vancomycin increases the probability of a prolonged need for RRT at discharge from ICU. The use of alternative antibiotics for certain patients, indicated by eGFR at admission, might be considered.

Influence of abdominal obesity on multiorgan dysfunction and mortality in acute respiratory distress syndrome patients treated with prone positioning.
Obesity is a worldwide pandemic, and obese patients face an increased risk of developing acute respiratory distress syndrome (ARDS). Prone positioning (PP) is a frequently used intervention in the treatment of ARDS. There are no data describing the impact of PP on morbidity and mortality in abdominally obese patients. We report our observations in abdominally obese ARDS patients treated with PP. ⋯ A cautious approach to PP should be considered in abdominally obese patients.
