Carbon Monoxide Improves Efficacy of Mesenchymal Stromal Cells During Sepsis by Production of Specialized Proresolving Lipid Mediators.
Mesenchymal stromal cells are being investigated as a cell-based therapy for a number of disease processes, with promising results in animal models of systemic inflammation and sepsis. Studies are ongoing to determine ways to further improve the therapeutic potential of mesenchymal stromal cells. A gas molecule that improves outcome in experimental sepsis is carbon monoxide. We hypothesized that preconditioning of mesenchymal stromal cells with carbon monoxide ex vivo would promote further therapeutic benefit when cells are administered in vivo after the onset of polymicrobial sepsis in mice. ⋯ Taken together, these data suggest that production of specialized proresolving lipid mediators contribute to improved mesenchymal stromal cell efficacy when exposed to carbon monoxide, resulting in an improved therapeutic response during sepsis.

The neural underpinnings of impaired consciousness and of the variable severity of behavioural deficits from one absence seizure to the next are not well understood. We aimed to measure functional MRI (fMRI) and electroencephalography (EEG) changes in absence seizures with impaired task performance compared with seizures in which performance was spared. ⋯ National Institutes of Health, National Institute of Neurological Disorders and Stroke, National Center for Advancing Translational Science, the Loughridge Williams Foundation, and the Betsy and Jonathan Blattmachr Family.

ReviewComplication of Community-Acquired Pneumonia (Including Cardiac Complications).
Community-acquired pneumonia (CAP) represents an important public health problem and carries significant morbidity, mortality, and costs. The incidence of CAP is highest among children and elderly patients, but the mortality is much higher in patients older than 65 years. Despite the advances in medicine, the administration of antimicrobials, and the overall better care, there are still patients with CAP dying due to systemic complications all over the world. ⋯ In this review, we present the characteristics of several CAP-related pulmonary and nonpulmonary organ dysfunction, such as those affecting the heart, kidneys, hematological, neurological, endocrine systems. Multiple severity of illness scores identified a series of systemic findings that indicate the organ dysfunctions and the associated related outcomes. However, further research is required to address the mechanisms, the management, and prevention of organ dysfunction in patients with CAP.
