Knowledge about the neuroinflammatory state during months after sudden cardiac arrest is scarce. Neuroinflammation is mediated by cells that express the 18 kDa translocator protein (TSPO). We determined the time course of TSPO-expressing cells in a rat model of sudden cardiac arrest using longitudinal in vivo positron emission tomography (PET) imaging with the TSPO-specific tracer [18F]DAA1106 over a period of 6 months. ⋯ After sudden cardiac arrest, TSPO remains expressed over the long-term. Sustainable treatment options for neuroinflammation may be considered to improve cognitive functions after sudden cardiac arrest.

Observational Study
Evaluation of the Initiation Timing of Hydrocortisone in Adult Patients With Septic Shock.
Clinical studies evaluating the use of hydrocortisone in patients with septic shock are heterogeneous in design with conflicting results. The appropriate time in which to initiate hydrocortisone after shock onset is unknown. This study sought to compare clinical outcomes including vasopressor duration and mortality in patients with septic shock who received hydrocortisone based on timing of initiation after shock onset. ⋯ In patients in whom hydrocortisone is prescribed for vasopressor-dependent septic shock, timing is crucial and hydrocortisone should be started within the first 12 h after shock onset.

Sepsis remains a major cause of mortality in critically ill patients. This study aimed to determine whether presepsin is a predictor of septic acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC), and shock. ⋯ Presepsin is a predictor of septic AKI, ARDS, and DIC. Combining presepsin values with GPS improved the specificity for predicting septic ARDS relative to using baseline presepsin values alone.
