Urinary Oxygenation as a Surrogate Measure of Medullary Oxygenation During Angiotensin II Therapy in Septic AKI
In septic acute kidney injury (AKI), renal medullary and urinary hypoxia developed several hours before increases in currently used biomarkers. Angiotensin II transiently improved renal function without worsening medullary... read more
High Morning Cortisol Tied to Long-term Anxiety in Family Members of ICU Patients
A new study published in the journal Critical Care Medicine finds that a biomarker may help identify which family members will be most emotionally impacted by their loved one's ICU stay. In particular, family members who... read more
Are Biomarkers Ready for Prime Time?
Kyle Enfield, MD, speaks with John A. Kellum, MD, MCCM, about his talk presented at the 46th Critical Care Congress in Honolulu, Hawaii entitled, "Are Biomarkers Ready for Prime Time?" Dr. Kellum works as an Intensivist in... read more
Updates on Sepsis from WSC
Fourth session from the World Sepsis Congress Spotlight: Maternal and Neonatal Sepsis - Updates on Sepsis.... read more
Platelets and Multi-Organ Failure in Sepsis
Platelets have received increasing attention for their role in the pathophysiology of infectious disease, inflammation, and immunity. In sepsis, a low platelet count is a well-known biomarker for disease severity and more... read more
Translational Evidence for Two Distinct Patterns of Neuroaxonal Injury in Sepsis
Ischemic and diffuse neuroaxonal injury to the brain in experimental sepsis, human postmortem brains, and in vivo MRI suggest these two distinct lesion types to be relevant. Future studies should be focused on body fluid... read more
Biomarkers in AKI: That’s All the Story?
We would like to add to the recent editorial by McMahon on biomarkers of acute kidney injury (AKI), with a specific focus on biomarkers in the clinical setting of cardiac surgery-associated AKI (CSA-AKI). We agree with McMahon... read more
External validation of a biomarker and clinical prediction model for hospital mortality in ARDS
Mortality prediction in ARDS is important for prognostication and risk stratification. However, no prediction models have been independently validated. We validated a mortality prediction model for ARDS that includes age,... read more
In Treating Sepsis, Questions About Timing and Mandates
The question of whether Rory's Regulations save lives isn’t asked or answered in the recent study. Sepsis deaths were already decreasing in the United States before the mandate, and determining its contribution to... read more
Heart Rate Variability in Critical Care Medicine
Heart rate variability (HRV) has been used to assess cardiac autonomic activity in critically ill patients, driven by translational and biomarker research agendas. Several clinical and technical factors can interfere with... read more
Sepsis Prediction in Critically Ill Patients by Platelet Activation Markers on ICU Admission
Platelets have been involved in both immune surveillance and host defense against severe infection. To date, whether platelet phenotype or other hemostasis components could be associated with predisposition to sepsis in critical... read more
Drink Coffee and Live Longer: Cohort Study
A multinational cohort study on coffee drinking and mortality in 10 European countries. Coffee drinking was associated with reduced risk for death from various causes. This relationship did not vary by country. 521, 330 people... read more
New Biomarker Improves Early Sepsis Detection in the Emergency Department
Sepsis most often presents to the emergency department (ED), and delayed detection is harmful. The white blood count (WBC) is often used to detect sepsis in the ED. New research shows that volume increases of circulating... read more
Generalizable Biomarkers in Critical Care
The sequencing of the human genome and the subsequent availability of inexpensive, robust methods for "omics" profiling (e.g., genome-wide association studies, gene expression microarrays, and metabolomics) have... read more
