Review Meta Analysis Comparative Study
Comparison of early and late norepinephrine administration in patients with septic shock: a systematic review and meta-analysis.
Vasopressor administration at an appropriate time is crucial, but the optimal timing remains controversial. ⋯ Overall mortality did not differ significantly between early and late norepinephrine administration for septic shock. However, early norepinephrine administration seemed to reduce pulmonary edema incidence, and mortality improvement was observed in studies without fluid restriction interventions, favoring early norepinephrine use.

Historical Article
The Public Health Leader Who Brought Antisepsis to William Halsted.
William Halsted wrote to aging surgeon, Stephen Smith, in 1919, that he remembered the lessons Smith had taught him, "when I walked with you through the wards of Bellevue Hospital." Smith was an early advocate of Joseph Lister's antiseptic method, and because of his public health work, he was also an early advocate of environmental hygiene and microbial control based on the unproved germ theory. Although Lister's work at the time emphasized germ killing around the operative site with carbolic acid (antisepsis), Smith adopted and encouraged surgical practices at Bellevue that would be hallmarks of the germ-preventing (asepsis) surgical approach that fully developed after German bacteriologic discoveries in the mid-1880s, and with which Halsted is historically identified. Some physicians and historians have emphasized temporal and conceptual differences between Lister's antisepsis and German asepsis, but Smith and Halsted's experiences argue that surgical asepsis was the evolutionary outcome of germ theory-based surgical changes that began well before scientific proof arrived.

Central venous saturation (ScvO 2 ) can guide resuscitation of children with septic shock. The normal range of ScvO 2 is typically considered as 0.70-0.80, but has not been established in children with cancer. Children with cancer are particularly prone to develop sepsis due to their immunosuppressive therapy, and usually have a permanent central venous catheter, making ScvO 2 readily available. We aimed to investigate normal values of ScvO 2 in clinically stable children with cancer, and the association between ScvO 2 , hemoglobin, and lactate. ⋯ The study revealed that a substantial portion of clinically stable childhood cancer patients exhibited ScvO 2 levels below the typical reference value of 0.70, suggesting that these children may have inherently lower baseline ScvO 2 levels. This should be kept in mind when evaluating children with cancer for septic shock, emphasizing the importance of tailored assessments in this population. Further understanding of baseline ScvO 2 abnormalities may be helpful if ScvO 2 is used to guide resuscitation.

This retrospective study investigated whether disturbances in circulating T-lymphocyte subsets could predict the incidence of acute kidney injury (AKI) and in-hospital mortality in patients with sepsis. ⋯ Patients with sepsis-induced AKI experienced T lymphopenia and increased in-hospital mortality. Higher maximum SOFA scores and reduced peripheral CD3 + and CD3 + CD8 + T-lymphocyte levels were associated with in-hospital mortality and the development of AKI in patients with sepsis.
