Assessing sepsis-induced immunosuppression to predict positive blood cultures.

Introduction: Bacteremia is a life-threatening condition that can progress to sepsis and septic shock, leading to significant mortality in the emergency department (ED). The standard diagnostic method, blood culture, is time-consuming and prone to false positives and false negatives. Although not widely accepted, several clinical and artificial intelligence-based algorithms have been recently developed to predict bacteremia.

Extracorporeal Blood Purification and Acute Kidney Injury in Cardiac Surgery: The SIRAKI02 Randomized Clinical Trial.

Importance: Cardiac surgery-associated acute kidney injury (CSA-AKI) remains a significant problem following cardiopulmonary bypass (CPB). Various strategies are proposed to attenuate CSA-AKI, including extracorporeal blood purification (EBP), but little is known about the effect of EBP through an acrylonitrile-sodium methallylsulfonate/polyethyleneimine membrane during CPB.

Objective: To determine whether the use of an EBP device in a nonemergent cardiac surgery population reduces CSA-AKI after CPB.

Oxiris Membrane in Sepsis and Multiple Organ Failure.

Sepsis and multiple organ failure (MOF) are characterized by multiple hemodynamic changes and imbalanced immune response of the patient. Oxiris is a highly adsorptive membrane with the ability to remove cytokines and endotoxins, as well as to perform renal replacement therapy. Here we describe the evolution from previous AN69 to the 3-in-1 Oxiris membrane, and review its characteristics and performance.

Regulation of Claspin by the p38 stress-activated protein kinase protects cells from DNA damage.

Stress-activated protein kinases (SAPKs) enhance survival in response to environmental changes. In yeast, the Hog1 SAPK and Mrc1, a protein required for DNA replication, define a safeguard mechanism that allows eukaryotic cells to prevent genomic instability upon stress during S-phase. Here we show that, in mammals, the p38 SAPK and Claspin-the functional homolog of Mrc1-protect cells from DNA damage upon osmostress during S-phase.

Temporal Incidence of Eriophyid Mites on Rose Rosette Disease-Symptomatic and -Asymptomatic Roses in Central Georgia, USA.

Keifer (Acari: Eriophyidae) is the vector of rose rosette virus (RRV), which causes rose rosette disease (RRD) in North America. The RRD symptoms, such as witches' broom, flower, and leaf deformation, disrupt the aesthetic appearance of plants and cause plant mortality. Because there is no cure for RRV, it is critical to manage the vector and reduce the spread of the virus.
